Cure Tooth Decay Heal And Prevent Cavities With Nutrition

About seven months ago, I walked out of a dental office with a pretty serious quote for dental work that was needed to be done on 8 different cavities they found in my teeth. I was confused. I eat a pretty good diet. How could my teeth have cavities? I brush and I floss every day. How could this happen? I told my dentist that I had heard about the â€Å"remineralization† of teeth and even curing tooth decay and cavities with certain staples in your diet, and asked him his opinion on the subject. Of course, like any conventional dentist, he had never heard of it. I’m pretty sure he even offered fluoride treatments at that point. After that, I stopped asking questions, scheduled an appointment to have all of the cavities filled, and left somewhat upset and unsatisfied. When I got home, I began researching natural ways to heal your teeth. I read the book â€Å"Cure Tooth Decay: Heal Prevent Cavities with Nutrition† by Ramiel Nagel, and learned about healing and remineralization of teeth with a good diet, and my mind was completely blown. I can actually heal my own cavities without spending thousands at the dentist? I can actually heal my cavities and remineralize my teeth with a proper diet? No more needles or drills in my mouth? Count me in! To completely understand how to heal your own cavities, we need to look at what causes tooth decay. Lack of Nutrition is the Root of Tooth Decay Dr. Weston A.

LDH Purification lab Report free essay sample

Abstract The enzyme lactate dehydrogenase (LDH) catalyzes the last step of anaerobic glycolysis that is important for the normal function of the body. Purification of LDH is essential to understand its structure and function. The purpose of this experiment was to extract and purify LDH enzyme from chicken muscle tissue using a variety of various. Analytical methods such as activity and protein assay were employed to determine the presence and purity of LDH. The cells were initially disrupted and proteins were solubilized. LDH was purified from the ammonium sulfate precipitated protein mixture by affinity chromatography and its activity was studied by spectrophotometric determination of NADH at 340 nm. From Pierce BCA assay of crude homogenate, initial protein concentration was shown to be 100 mg/ml. The final protein concentration of the pooled affinity sample was shown to be 0.2 mg/ml. It was found that the total specific activity of LDH was 58.5  µmol/min/mg, and yield of 0. 6%. Even though we were successful in purifying LDH enzyme, further steps can be taken to increase the yield. Materials and Methods Cell Lysis and Extraction of LDH: Approximately 40 g of minced chicken breast meat (40.327 g) is blended with 75ml cold extraction buffer in four 30-seconds bursts for homogenation of the muscle tissue. The extraction buffer contained 10mM Tris-HCl (pH-7.4), 1mM 2-Mercaptoethanol, 1mM Phenylmethylsulfonylflouride (PMSF), 1mM Ethylene diamine tetraacetic acid (EDTA). The homogenization procedure was carried out in the cold room to prevent the denaturation of proteins. The homogenate was centrifuged at 15,000 rpm for 20 minutes at 40 C. The supernatant was filtered through two layers of cheesecloth to remove lipids from the supernatant. The total volume was noted and three 0.5 ml aliquots (crude extract) were stored at -200 C. Ammonium sulfate precipitation: 60% ammonium sulfate concentration was used to precipitate proteins. 0.39 g of ammonium sulfate per ml of the  supernatant was added gradually to the supernatant for 15-20 min with continuous gentle stirring at 40 C. The mixture was centrifuged for 20 minutes at 15,000 rpm at 40 C. The supernatant was discarded and the pellet was stored at -200 C. Dialysis: Ammonium precipitation leads to high concentration of salts in protein mixture that can interfere with further purification steps. In order to remove excess salts, dialysis was performed. The pellet was suspended in Tris-PMSF buffer (10 mM Tris-HCl, pH 8.6, 0.5 mM 2-Mercaptoethanol, and 1mM ratio of EDTA) and mixed very gently until it dissolved at 40 C. Volume of 4ml protein mixture was added in the dialysis tubing and incubated twice overnight with two 1L buffer changes (Same buffer as extraction buffer that was used for cell lysis). After two incubations, protein mixture was resuspended gently and centrifuged for 10 minutes at 15,000rpm at 40C. Pellet was discarded, total volume of supernatant was noted and three 0.1 ml aliquots were collected. Affinity Chromatography: Cibarcon Blue column was used to separate LDH from the other proteins. 5ml fractions were collected in thirteen test tubes. Column was first rinsed with Tris-PMSF buffer followed by addition of protein mixture. Then, 10ml NAD Buffer (10mM Tris-HCl pH-8.6, 0.5mM 2-Mercaptoethanol, 1mM Lithium acetate and 1mM NAD+) was added followed by 10ml NADH (10mM Tis-HCL PH 8.6, 1mM NADH and 0.5mM 2-Mercaptoethanol). Between each steps, column was washed with 10ml Tris-PMSF Buffer. Each fraction was subjected to absorbance reading of 280nm. For absorbance above 1.5nm, 1:10 dilutions were carried out. Activity Assay: We used LDH Enzyme assay to measure the amount of LDH activity in our protein mixture. LDH catalyzes the conversion of lactate to pyruvate and NAD+ to NADH. The NADH can be determined spectrophotometrically at 340 nm. The LDH assay was performed in the crude homogenate, desalted fraction and six peak fractions from the Cibacron blue column. A cocktail solution was prepared by mixing lactate stock solution (120 mM lithium lactate, 10 mM Tris-HCl; pH 8.6), NAD+ stock solution (12 mM NAD+, 10 mM Tris HCl; pH 8.6) and bicarbonate stock solution (18 mM NaHCO3, 0.5 M NaCl)  in the ratio of 6:4:2 in cuvette. 10 microliters of the sample is then added and the assay absorption is measured at 340nm. If absorbance was above 1.5, samples were diluted. Protein Assay: The Pierce BCA Protein Assay (Thermo Scientific) is a detergent-compatible formulation based on bicinchoninic acid (BCA) for the colorimetric detection and quantitation of total protein concentration. A series of standard solution of Bovine Serum Albumin (BSA) ranging from 0-2000  µg/ml was prepared from a stock solution of 2 mg/ml BSA. 25ul of diluted crude (1:500, 1:250), desalted (1:100, 1:50), and 6 peak fractions from cibarcon blue column (1:10, 1:5) were loaded in microplate along with 175ul of BCA working reagent. Microplate was incubated for 30min at 370C and then the absorbance was measured at 562nm. Results/Discussion The purpose of this experiment was to extract and purify LDH enzyme from chicken muscle tissue using a variety of techniques including homogenization, ammonium sulfate precipitation, dialysis, and affinity chromatography. Activity and Protein assay were used to track the overall amount of LDH present in the samples. Crude Extraction: Chicken muscle tissue was homogenized in a blender with cold extraction buffer in order to lyse cells, releasing LDH into slurry of tissue components. Centrifugation separated membranes, nuclei, and other large cellular components to a pellet leaving a supernatant of crude product. Controlling temperature was a major consideration after homogenization since not only did this step releases proteins like LDH from the cell, but it also releases proteases that can now interact to degrade the LDH. Keeping samples on ice, pre-cooling the buffer, and avoiding excess kinetic energy through conservative blending were methods used to minimize activity of these proteases. After filtration through cheesecloth, our final volume of crude homogenate sample 74ml, much more volume than expected. Addition of more than 75ml of buffer volume could have increased the volume. Other possible explanation is that more solid components such as fats were present in the sample and hence, more than 20 minutes of centrifugation was  required. Desalted Sample: 60% ammonium sulfate is added to the crude extract that precipitates LDH proteins. The resulting 40% pellet theoretically contains most of the original LDH, which is re-suspended in very less volume (4ml) to create a more concentrated sample. This process leads to high concentration of salts in protein mixture that can interfere with subsequent purification steps. 4ml protein mixture underwent dialysis procedure that removes excess salts and our final volume after dialysis was 6ml. One possible explanation for increase in our volume could be that extraction buffer got mixed with protein mixture either due to tubing leaking or tubing clips not being properly tightened. Affinity Chromatography: Cibacron Blue column is an affinity column, which is specific to dehydrogenase type proteins, due to a compound structurally similar to NADH being attached covalently attached to the column. 13 fractions were collected and absorbance was measured at 280nm to check presence of LDH protein in the fractions. 1:10 dilution was performed if absorbance reading was above 1.5nm since it spectrophoretically indicates saturation and less than 1% light reaching the detector. During the addition of protein mixture (fraction# 4), high absorbance reading of 10nm was obtained (Fig.1). This could be due to lot of non-dehydrogenase-type proteins present in our sample that got eluted first during affinity chromatography. Second peak was seen after NAD+ was added since NAD solution results in the removal of the loosely bound protein. Third peak was seen after NADH was added since NADH solution results in release of maximum LDH proteins (Fig. 1). Enzyme Activity Assay: The LDH activity was measured spectrophotometrically by measuring the absorbance of NADH at 340 nm. Three peak fractions were selected for this assay based on their absorbance values obtained after adding NAD+ (fraction# 6, 7, 8) and other three after adding NADH in the affinity chromatography step (fraction# 10,11,12). A huge activity of 141umol/min/ml was seen at fraction# 7(PF1) which indicated that we had lot of proteins present in our sample. Second peak activity was seen at fraction #10 indicating that more LDH proteins is present in this fraction than in fraction# 11 (PF2) (fig.1). Based on this information, we selected fraction #10 as for our protein assay. Desalted showed highest activity among all the samples (Table1) possible due to errors occurring during dialysis explained previously. Figure 1. Absorbance readings of elutes obtained from affinity chromatography with LDH activity for 6 peak fractions. The desalted fraction was loaded to the Cibarcon blue column and proteins were eluted with Tris-PMSF, NAD+ and NADH wash subsequently. The absorbance at 280 nm of elutes were measured after each collected fractions. The LDH activity was calculated from the absorbance values obtained at 340nm. Protein Assay: We used BCA Pierce Assay to determine protein concentrations in our protein mixture. BSA standard curve was created for series of dilutions ranging from 0-2000  µg/ml and linear graph equation was used to calculate protein concentrations for the samples (Table 1). Based on Table 1, with each subsequent purification step, protein concentration decreases as sample become more concentrated with only LDH protein. Specific activity should increase and total activity should decrease with every purification step as samples get less and less diluted. Similar trend was observed in our study as well. However, exception is PF1 that has higher specific activity due to high activity suggesting more loosely bound proteins were eluted after NAD+ was added.

madonna and child Essay Giovanni Bellini was born in 1426 1516. He was born in Venice, Italy. His father, Jacopo was also a painter. Giovanni more than likely began his career as an assistant in their fathers workshop. In hisfirst years as an artist Bellini was strongly influenced by his brother-in-law, Andrea Mantegna, from who he took a sculptures figure style. Giovanni Bellini was the founder of founder of the Venetian school of painting. He raised Venice to a centre of renaissance art that rivalled Florence and Rome. I will discuss two of his paintings further on in the essay. Madonna with the child (Greek Madonna) Madonna of the Meadow (Madonna del Prato) Madonna with the Child (Greek Madonna) 1460-64, Bellini Rafaello Santi was born in Urbane on good Friday 6th Aril 1483. His father was a painter and poet and worked for Frederica da Montefelto who was of the most famous princes and art patrons of the early Italian renaissance . Raphael helped his father in his studio from an early age. This is wh ere he is believed to have learned about art. His father died in 1494 and in 1504, Raphael moved to Florence and lived there for four years. He studied works by Leonardo da Vinci and Michelangelo here which inspired him even more. It was in Florence he began his series of Madonnas. I will talk about two of his Madonna paintings later. The Small Cowper Madonna Raphael c1505 In this essay I am going to discuss Raphaels and Bellinis approach to the theme Madonna and child. Both Bellini and Raphael painted many versions of the Madonna and child, both viewed this theme as a religious one however we can see that both portrayed the Madonna and child differently. Raphael painted Madonna and childs relationship as a warm and loving one. Be

AIDS - Whats New Essays - HIVAIDS, HIV, , Term Papers

AIDS - What's new ? ------------------- Is the message getting through? We already know enough about AIDS to prevent its spread, but ignorance, complacency, fear and bigotry continue to stop many from taking adequate precautions. We know enough about how the infection is transmitted to protect ourselves from it without resorting to such extremes as mandatory testing, enforced quarantine or total celibacy. But too few people are heeding the AIDS message. Perhaps many simply don't like or want to believe what they hear, preferring to think that AIDS "can't happen to them." Experts repeatedly remind us that infective agents do not discriminate, but can infect any and everyone. Like other communicable diseases, AIDS can strike anyone. It is not necessarily confined to a few high-risk groups. We must all protect ourselves from this infection and teach our children about it in time to take effective precautions. Given the right measures, no one need get AIDS. The pandemic continues: ----------------------- Many of us have forgotten about the virulence of widespread epidemics, such as the 1917/18 influenza pandemic which killed over 21 million people, including 50,000 Canadians. Having been lulled into false security by modern antibiotics and vaccines about our ability to conquer infections, the Western world was ill prepared to cope with the advent of AIDS in 1981. (Retro- spective studies now put the first reported U.S. case of AIDS as far back as 1968.) The arrival of a new and lethal virus caught us off guard. Research suggests that the agent responsible for AIDS probably dates from the 1950s, with a chance infection of humans by a modified Simian virus found in African green monkeys. Whatever its origins, scientists surmise that the disease spread from Africa to the Caribbean and Europe, then to the U.S. Current estimates are that 1.5 to 2 million Americans are now probably HIV carriers, with higher numbers in Central Africa and parts of the Caribbean. Recapping AIDS - the facts: --------------------------- AIDS is an insidious, often fatal but less contagious disease than measles, chicken pox or hepatitis B. AIDS is thought to be caused primarily by a virus that invades white blood cells (lymphocytes) - especially T4-lymphocytes or T-helper cells - and certain other body cells, including the brain. In 1983 and 1984, French and U.S. researchers independently identified the virus believed to cause AIDS as an unusual type of slow-acting retrovirus now called "human immunodeficiency virus" or HIV. Like other viruses, HIV is basically a tiny package of genes. But being a retrovirus, it has the rare capacity to copy and insert its genes right into a human cell's own chromosomes (DNA). Once inside a human host cell the retrovirus uses its own enzyme, reverse transcriptase, to copy its genetic code into a DNA molecule which is then incorporated into the host's DNA. The virus becomes an integral part of the person's body, and is subject to control mechanisms by which it can be switched "on" or "off". But the viral DNA may sit hidden and inactive within human cells for years, until some trigger stimulates it to replicate. Thus HIV may not produce illness until its genes are "turned on" five, ten, fifteen or perhaps more years after the initial infection. During the latent period, HIV carriers who harbour the virus without any sign of illness can unknowingly infect others. On average, the dormant virus seems to be triggered into action three to six years after first invading human cells. When switched on, viral replication may speed along, producing new viruses that destroy fresh lymphocytes. As viral replication spreads, the lymphocyte destruction virtually sabotages the entire immune system. In essence, HIV viruses do not kill people, they merely render the immune system defenceless against other "opportunistic: infections, e.g. yeast invasions, toxoplasmosis, cytomegalovirus and Epstein Barr infections, massive herpes infections, special forms of pneumonia (Pneumocystis carinii - the killer in half of all AIDS patients), and otherwise rare malignant tumours (such as Kaposi's sarcoma.) Cofactors may play a crucial contributory role: ----------------------------------------------- What prompts the dormant viral genes suddenly to burst into action and start destroying the immune system is one os the central unsolved challenges about AIDS. Some scientists speculate that HIV replication may

Economic growth in Australia since 2000 Australia has been standing out among OECD countries due to its sound economic policies. However, the slow growth of Australia’s economy is because of the financial crisis of 2008-2009. Australia is making efforts for the adjustment in the structural changes that is due to the commodity bang (OECD Economic Surveys Australia, 2012). The recent mining boom initiated in the year 2000 that led to the esca lating cost of commodities linked with mining. The following figure illustrates the rise in the non-rural commodity prices: Fig-4: Non-rural commodity prices: Source: Index of Commodity Prices, Reserve Bank of Australia as cited in Pham et.al, 2013, p.2 The mining boom has affected the Australian economy in some way or the other.Advertising We will write a custom essay sample on Sustaining Australias rate of economic growth specifically for you for only $16.05 $11/page Learn More The export companies as well as the struggling import businesses have made the Australian dollar to trim down the price competitiveness in the international market. â€Å"The Reserve Bank of Australia declared that the mining- related commodity prices peaked in August 2011, and are now down by around 23 percent from this peak.

Figure 4: The following chart shows Australia’s Gross Domestic product growth Source: ABS Cat. No. 5206.0, Australian National Accounts as cited in Pham et.al, 2013, p. 3 Sustaining economic growth in future The constant uninterrupted economic growth of Australia for past two decades will sustain in two conditions in near future: 1) the potency and span of the resources boom; and 2) productivity growth. Australia’s income growth in near future will depend upon maintaining a scenario that involves returning productivity growth to its historical standards, maintaining the terms of trade bringing all the advanced ventures and three-quarters of the partially developed projects to the stream. However, that too would ensure only 3.7 percent income growth as compared to the standard growth of 4.1 in the past. But the w orst-case scenario is draws attention that suggests that the terms of trade is leaning toward their long term average there is likely to be only two-thirds of advanced capital projects and one-third of the less advanced projects coming to realization and suggests no development in the current productivity growth. This sobering scenario may be threatening to the Australian income growth of 0.5 percent till 2017. Figure 5: Source: Taylor et.al, 2013, p.4 Mining and non-mining Sectors Conventionally, the economy of Australia can be divided into two-speed economy. One is a flourishing resources segment and the other comprises of all other gradually developing segments. However, it is wise to see Australia’s economy divided into four parts. The following figure illustrates the four sectors with respect to their link with the resources. Figure 6: Source: Taylor, et.al,2013,p.5 Resources sectors: Enforce capital productivity for successful investment According to Shann (2012), the speedy growth yet decreasing capital productivity in the resource sector has been evident in Australia’s economy. The lowest ridge in the scenarios for future income escalation is suggestive that future investment in the resource sector will surpass the previvious levels of income growth. There is an urgent need to get the capital productivity right that may lead to the prospective income growth (as cited in Taylor et. al, 2013). To capture the gains, it is necessary that the individual companies and the policy makers work together. Government is required to provide support through providing environmental approvals, development of the infrastructure, and enhancing industrial relations so that there can be balance maintained between growth and other social good. Resource rider sectors: Need to improve efficiency The other sectors like transport and professional services have also been affected by the mining energy boom; however, these have witnessed decrease in productivity. â€Å"These sectors attracted the vast majority of the overall economy’s increase in labor from 2005 to 201, but the contribution of labour productivity to sector output fell to zero during this period† (Taylor et.al 2012,p.6). It is important that new ways and more integrated cross-sector approach in resource productivity should be incorporated to make the infrastructure development more cost efficient. Local services: committing again to microeconomic reform Local services like retail trade and telecommunications do not exhibit any major impact of the resources boom. These sectors have shown solid productivity growth of A$49 billion to the overall income growth in 2005-2011. It is important that efforts from the individual companies in the form of innovative operating representation and government’s endeavor to rationalize regulation, promote improvement and encourage competitive markets can boost productivity. For this purpose, Australia needs to adopt the mi croeconomic reform as it did in 1990s. Manufacturing: Creating the base for long-term competitiveness Australia has seen continuing erosion in manufacturing productivity and employment. There has been a significant decrease in the capital productivity in the past six years except for the limited counterbalance created by the labor productivity. Improvement in the manufacturing sector can be derived through further cost efficiencies in the subsectors that contend mainly on price, enhancing labour mobility in the manufacturing sector along with a strong and facilitating ecosystem for bringing novelty in manufacturing. These measures can bring extra national income of about A$ 90 billion a year and sustain the historic scenario by 2017(Taylor et.al, 2013). Outlook It is difficult to state with surety when the climax will come about and the speed at which the mining investment will descend as a share of GDP. The decisive factors will be the actions taken on the uncommitted ventures and the speed of development in the existing projects along with the degree and features of the added overruns. However, there is a possibility of increased mining investment for quite some time as a huge bulk of work is still in progress. With the mining investment becoming weaker, it will enter upon the set phase of mining boom. The exports will rise as a reaction to the investment that has been taken on. The manifested growth in the resources like iron ore, coal and LNG exports for some time is suggestive of the further growth in these resources from 2015. Figure 7: Source: Kent, 2013, Para 14 Conclusion The trend in the mining investment reflects that the economic growth will be a little less around and will pick up later in 2014.As the growth rate of sectors other than the resources sector is gradual, it is better to observe the signs for some more time (Kent, 2013).

The Effects of Competition, Predation and Disturbance Essay

The Effects of Competition, Predation and Disturbance - Essay Example The predator is the population that attacks and hunts the prey population for survival. The process of predation ultimately leads to the death of the prey in cases which are either intentionally or unintentionally and also directly or indirectly undertaken by the predator. The said process then can be defined as consumption of the prey population. There are different types of predation that are undertaken by the four types of predators namely the true predators, the grazers, the parasitoids and the parasites. The said classification is based on the type of action wherein the process of predation is completed. The process of predation can result in different effects which can either be beneficial or detrimental to the prey population, predator population and the ecosystem in general. One of the most important effects of predation is the maintenance of balance between species population by prevention of the domination of a single type of organism in a community. The said process can be attributed to the action undertaken by the predators. For that matter, predation can be beneficial to the predators. On the other hand, the prey population is the main group that can achieve the detrimental effects of the process of predation. Although this is the case, due to the interactions of the different organisms in an ecosystem as exemplified by the food web and food chain, an organism can be a prey of a larger species while at the same time a predator of a smaller species. This process of interaction is the main cause for the achievement of the ultimate balance in the ecosystem. One of the ways to better understand the predator-prey interaction is through the use of the Lotka-Volterra model.  

IP4 Essay Example | Topics and Well Written Essays - 500 words

IP4 - Essay Example Pioch (2002) described the era as associated with religious art. Baroque period is characterized by vigorous movement and emotional intensity associated with Baroque art in its primary meaning. Much Hellenistic sculpture could therefore be described as `baroque'. The older meaning of the word means `capricious', `overwrought' or `florid' (Pioch, 2002). Caravaggio and Annibale Carracci are the two great figures who stand at the head of the Baroque tradition, bringing a new solidity and weightiness to Italian painting, which in the late 16th century has generally been artificial and often convoluted in style (Pioch, 2002). The two artists are considered to have their own style in which Annibale's work has an exuberance that is completely his own, and Caravaggio created figures with an unprecedented sense of sheer physical presence (Pioch, 2002). These two major artists have great influences of their own and fusing these influences, the Baroque area arose (Pioch, 2002). Baroque artists inherited from the mannerist style the movement and fervent emotion and solidity and grandeur from Rennaisance style (Pioch, 2002). The Deposition from the Cross is an artwork made by oil in canvas. This is considered one of the greatest works of Caravaggio. In this artwork, the artist did not really portray the Burial or Deposition in the conventional way.

Seagull play by anton chekhov Research Paper Example | Topics and Well Written Essays - 1000 words

Seagull play by anton chekhov - Research Paper Example He helped his father who ran a small business of provisions that was quite unsuccessful. However, it was during these hard days at his father’s shop that he observed and listened to some interesting stories from those who visited. During the summers he went to stay with his grandfather who had become the manager of an estate near Taganrog. He loved spending his time with the peasants who worked on the estate and enjoyed fishing and roaming about in the countryside. When Chekhov was around fourteen years old, his father moved the family to Moscow and he was relieved from working in his father’s shop. It was then that he began to make good progress in his studies and finally became a student of medicine. In his attempt to help his family, he led the dual life of student and author and it is with these experiences he emerged as a blazing genius of both wit and compassion. The characters in Chekhov’s story are most endearing as some of them long for love but do not g et it and some of them experience love but do not fulfill it. The main characters in the play are Treplev, a playwright who is anxiously getting things ready to stage his first play that is both abstract and symbolic in meaning. He loves and adores Nina, an actress who does not reciprocate his love till the end of the story. Nina on the other hand, is shown to pursue Trigorin, a creator, because she becomes in awe of him, but is left bereft of his love in the end. She goes to the extent of having an affair with him, becoming pregnant and even suffering the loss of her baby, but she does not win his love till the end. One of the other main characters in the story is Treplev’s mother Arkadina, who is a quite a celebrated actress and loves Trigorin. On the other hand, Trigorin seems to be playing double shuffle between Arkadina and Nina, professing his love to each of them at different times. Arkadina is selfish and self-centered and shows her dislike for her son Treplev’ s play. She rudely interrupts the play several times until Treplev is forced to bring the curtains down on the play. Though her son longs for her love and acceptance, she is too conceited to realize and reciprocate his love, neither does she show him any sympathy or encouragement. Medvedenko, who is a poor school teacher, is madly in love with Masha who is the daughter of Shamraye, the manager of an estate. Masha tells Medvedenko in clear terms that though she knows that he loves her, she cannot love him in return. But finally we find that both of them come to terms with their feelings for each other and get married and settle down. The Seagull depicts a poignant love story that focuses its attention on the playwright’s tragic love quest for Nina, the beautiful actress who rejects his sincere love. He craves to be loved and admired by Nina, who does not reciprocate his love in the least. When his play does not turn out successful he is ridiculed and scoffed at by his mother a nd all those around her. He yearns for solace from Nina but receives nothing from her. In quite a symbolic manner he brings a dead seagull and places it at her feet and tells her that she does not love him because his play was not a success. Chekhov uses the dying seagull to symbolize the pain of defeat and suffering and its acceptance through death. All the other characters in the play support the theme of unrequited love by reflecting the pain and suffering of their own lives. While

Digital Media And Print Media: Dying Out

Digital Media And Print Media: Dying Out With reference to the presentation of Fenna Statz on the 14th of December, in which we spoke about the problem that due to digital media, print media no longer will exist in the near future. I hereby want to talk about the problem, to offer a conclusion and a solution. The problem is that print media is dying. Since the first facts of electronic media and print media has always felt an undue threat. First was the radio and then to the television. Now the internet is apparently up against the vast and widely spread print media. Or print media is dying, is a question that a lot of marketers ask themselves from time to time. Whether they believe in the power of the printed word or choose to put all their advertising dollars into digital media. This report is to provide you more detailed information about the problem that print media is dying and if it will exist in the near future. Everyone knows already what digital media is, but most of the people have no idea what it is and how it can help you out when it comes to marketing. It is very important that you get up to speed so you can use this to benefit your business. In fact digital media refers to any type of electronic media out there. Today media has accessed in many ways, including with hand held devices like mobile phones, laptops, desktops, mp3 players, and more. The digital media will take over the world. You can read everything on the internet and everybody has their own network, like social media. Social networking sites are the websites using which you can make new friends and find out your old friends. Not only making and finding friends you can also find many other services available in networking sites. Usually all the networking sites work in a similar way. The difference is just of rules and regulations. Usually people who join these sites have some common reasons like finding old friends, makin g new friends, dating, religion, etcetera. There are many forms of social media, the most common are: Twitter, Facebook and MySpace. Facebook is the largest social networking site for people connecting with friends and others. More than 500 million people are active users on Facebook, 50% of the active users log on to Facebook in any given day. The average user has 130 friends and people spend over 700 billion minutes per month on Facebook. MySpace is the same platform as Facebook, and is commonly referred to as a place for friends. Twitter has 190 million accounts. Almost 91 percent of the Dutch youth is active in the social media. This includes the Dutch youth to the top of the European Union. Only Polish people make more use of social media almost 94 percent. The use of social media decreases with age. In the age group 25 to 55 years, the proportion of those active in social networks in the Netherlands and 54 percent of the age of 55 to 75 years just over 30 percent. Print media advertising is exactly what it says, it is advertising in a print media arena. The two most forms of print media advertising are newspapers and magazines. Print media also includes many other advertising like: Posters on buses, trains, toilet rooms, subways and a lot of other thing. Also outdoor billboards, ads in phone books, flyers, etcetera. The proportion of Dutch says that someone in their household has subscribed to a newspaper, decrease from 62 percent in 1997 to 50 percent in 2008. This decrease may be related to the emergence of a number of free newspapers. I think that in the future the people will read the news on the internet. News breaks are much faster online than in any other medium, except for live television. From all that facts of above it can be concludes that now it is very clear where the trend is headed, so no doubt, print media in its traditional form will decline. But I do not think that it will cease to exist in 10 years. Printed media will be less, but there will always be a need for a printed copy by the people. With print media you can share it and you can move it. So keep that fact in your mind if you develop a media strategy. Studies have shown that print advertising has a lower ROI and that should bring down the cost of advertising soon. Think of it is a non expensive channel to advertise. While we are used to accessing news in real time from the web, print media will still have a role in providing content where timing is not an issue. And the transition to a digital world will not be accomplished within 10 years. I think that will take over more than 100 years. The government could not forbid the newspapers because it will be always a need by many people.

Economic system in Egypt :: essays research papers

THE ECONOMIC SYSTEM IN EGYPT PRIVATE SECTOR: Ready for action As Egypt is known for it’s mixed economic system ,Compared with other emerging markets, Egypt's private sector is tiny. The public sector still accounts for almost 70 per cent of GDP despite the fact that hundreds of public enterprises have been wholly or partly privatised during the past four years. Judging, however, by the rapid growth of some of the country's largest family-owned businesses, this is unlikely to hold true five years from now. Raouf Ghabbour, chairman of Ghabbour Group, a family business and the country's largest assembler and distributor of motor vehicles, says there are hundreds of medium-sized companies which are growing fast enough to qualify for joint-stock status within three or four years. Ghabbour Group is one of only a dozen or so unlisted private sector companies with a turnover of more than EÂ £1bn. This is considered a minimum threshold for a company to launch a successful public listing. "Our turnover has been growing at about 25 per cent a year this decade," says Mr Ghabbour. "There are countless small and medium-sized companies with this kind of growth rate." Much like Orascom, Egypt's largest family-owned group, which has interests ranging from tourism to telecoms separated into several publicly listed companies, Ghabbour has been converted to the benefits of going public. The car assembler, which also has a growing consumer loan subsidiary, hopes to offer 10 to 15 per cent of its equity in an initial public offering later this year. Others, including IGI, a diversified family-owned group with interests in manufacturing, dairy farming and petroleum, are thinking along similar lines. "There are probably about 10 or 12 family companies with similar plans," says Khaled Sheta, chief executive of International Group for Investment. "All of them will be quoted in a year or two from now." Mr Sheta provides justification for such a move. "Opening your books to the public acts as a good business discipline on managers and enables you to value your assets more accurately," he says. It is also, of course, a handy way of raising capital without having to cede majority control of the company. Indeed, for the few that have achieved genuine nation-wide market share in their industries, there is little choice but to go public or offer stakes to strategic investors if they want to continue expanding. Being so small in number, companies such as Ghabbour and Mansour, which has the Coca-Cola and McDonald's franchise in Egypt, are inevitably bumping up against credit limits to their banks.

Photography Essays - Sierra Club, Ansel Adams, Hypochondriacs

Photography Essays - Sierra Club, Ansel Adams, Hypochondriacs Photography Today it has become a truism to say that the medium of photography is light. But the skill required to capture that light in ways that celebrates its beauty and mystery has been mastered as fully by Ansel Adams as by almost any other twentieth-century photographer. And it seems highly appropriate that the name of the exhibition contains the words FIAT LUX: let there be light, As a case in point we may contemplate the beautiful fragment of Bristlecone Pine Wood at the White Mountain High Altitude Station. Here the stark light-dark-light contrasts reveal Adams at his best. While the sunset's light accentuates the shapes of the wood at its edges, so that it glows with luminescence, the darker tonalities remind us that this fragment is as much dead as it is alive, and thus reminds us of our own mortality. For me this image also suggests that we pay greater attention to the cultivation and preservation of nature, its delicate balances, which, when neglected, lead to devastation, as is occurring in the rain forests of Brazil. Even in juxtaposition with death, however, this lovely Adams image speaks of the glory of life. I don't know of a more spectacular view than the one from the top of the Berkeley hills across the San Francisco Bay toward the city, and the Golden Gate Bridge in the distance. The silent serenity of this photograph contrasts markedly with the devastation of recent events. As beautiful as this image is we also know that many areas of the greater area of the San Francisco Bay are polluted. In a photograph taken from the Lick Observatory the scientific facility is not visible, but we still, with the knowledge of the vantage point from which it was taken, sense the precarious balances of nature and technology, which so universally threaten the existence of both, including threats to outer space, reminding us to heed the ever-increasing warnings of pollution. The misty delicacy which characterizes this photograph of rolling hills, outlined with light, and trees, which are threatened by drought, makes us wonder how long these species will remain. Whether young or old, located in a city, or in more remote environs, whether researching the fruits of the earth or the mysteries of outer space, these never-before-exhibited images provide a wealth of visual information about the varieties and richnesses of our world.

A Child's Drawing Expresses Their Psychological Ability and Feelings Essay

A Child's Drawing Expresses Their Psychological Ability and Feelings - Essay Example Talking does not offer a comprehensive medium of expression. According to Golomb (pp. 42), a child’s hidden feelings can only be expressed by art, specifically drawings. Be it small or a large drawing so much can be said from the piece of art. Other than career and professional drawings, drawings have been used to detect the feeling in most children who undergo psychological problems. In some instances drawings as an art has been used as anger management tool. This is an indication on how important art is in managing of human emotion. In an argument by Herne, Cox & Watts (pp. 115), a child’s drawings expresses about 75% of their internal feelings both emotional and psychological. In interpreting the drawings psychologists consider color, size, location of characters, characters, page location, font and shading type and the facial expression of child when drawing an image or character. Apart from the expression of feelings, drawings at different ages in children denote t heir psychological growth. From scribbling to real images and drawings is one notable feature in child development when drawings are concerned. It is this fact that has enabled me to come up with the theory that â€Å"a child’s drawing expresses their psychological ability and feelings†. This paper will focus on how drawings show a child psychological growth and interpretation... This stage is known as fortuitous realism. At this stage a child understands scribbling as the best work of art they can achieve. However, as much as scribbling can be seen as insignificant, the way scribbling is done by a child can tell more about their emotion and psychology. Some children may scribble dark scribbles while at times scribble gentler and light scribbles. According to the American Counseling Association (pp. 34) this may denote anger or frustration and also satisfaction and happiness respectively. The second stage occurs between the ages of 4 – 7. This stage is known as preschematic stage. This stage is categorized into two stages of development. The stages are failed and intellectual realism. In the failed realism a child draws elements that are completely unrelated from the real image of the element. Intellectual realism is when a child draws an element from their knowledge. For instance, a child may draw a cup since the image is in their brain. The third sta ge of development is the schematic stage. The stage comes up between the ages of 8 – 9. In this stage a child draws what they see. The element shows the features of the real image. This is aimed at transferring their visual sense to the mental sense then the interpretation follows. It is also noted that this point kids differ from the accuracy of their drawings. At this point is where the visual and interpretation abilities of children are noted. Different children have different visual and interpretation prowess. This indicates that the psychology of children differs depending on their mental abilities. The three stages show that drawings effectively indicate the psychological growth and strength of children.

Xuyu - Coursework Example In addition, the feeling improves children self-image and social relations. Marla is highly vulnerable to develop prejudices than Jane because of her negative attitude towards Bernadette’s situation. She criticizes Bernadate, yet fails to analyze possible causes for her poor performance. However, Jane is more understanding and supportive. Despite Bernadate’s poor performance, she understands the impact of divorce on concentration. Conversely, Marla lacks personal skills to understand the feeling of others, and control of negative thoughts. Older childrens ability to analyze information improves their perspective taking, emotional and moral understanding of themselves and others. Thus, mature children easily comprehend life difficulties and appreciate role of their friends. For instance, older children analyze and strive to fit in friends’ situations in times of challenges. The children offer moral support to their friends because they fully know impacts of life experiences. I never attended integrated elementary school. However, benefits of integrated school in child development and reduction of ethnic and racial and prejudice are enormous. The schools facilitate cross-cultural understanding. Principally, integrated schools minimize cross-racial discrimination, damaging bias and

Communication Term Paper Example | Topics and Well Written Essays - 1750 words

Communication - Term Paper Example However, I believe that the convenience and ease that mobile phone communication brings have a drawback and that is making the quality of communication superficial. In my opinion, the impersonality of communication that mobile phones have brought into people’s lives actually moves people apart and allows them to go their own way and refuse socialization which then creates a disconnected society. Upon reading Louis Menand’s article entitled â€Å"Thumbspeak. Is Texting Here to Stay?† it made me think about the underlying effect of the kind of communication that mobile phones bring into our society. True indeed that mobile texting has become a worldwide phenomenon because it delivers the message to the recipient in a fast, convenient and, most importantly, affordable manner (Menand). It does not matter anymore where the receiver of the message is located because a mobile text message can reach anybody from any part of the globe. I will not deny the fact that the us e of mobile phones brings many benefits to its users. The most apparent advantage of texting is that it accelerates communication (Menand). For instance in the road, the speedy form of communication brought by mobile phones can actually save lives when there is a pressing need to call the emergency hotline. With the use of cell phone, people can immediately call for help that often minimizes the emergency response time and saves more lives on the road. In terms of business, the advantages of using cell phone for businessmen and women are endless, and this encompasses cell phone use even while driving. Business people are supposed to be always reachable especially by their clients because it is going to be huge loss if they miss just one transaction. For business people, work-related issues are on the top of their list and this means being available to address and resolve these issues at any time, regardless of the locations. In terms of relationships, it is not new anymore that ther e are times when men and women rather communicate their thoughts or emotions towards another person through texting or calling via their mobile phone. â€Å"A less obvious attraction of texting is that it uses a telephone to avoid what many people dread about face-to-face exchanges, and even about telephones—having to have a real, unscripted conversation† (Menand). The use of cellular phones on a daily basis is an indication of the construct of efficiency and multi-tasking. It has emphatically made people’s lives easier, particularly communication. Imagine the convenience of talking to a family member or a colleague while we are at the mall and doing shopping. Imagine the ease of having a three-way business conference while we are at home doing household chores or, perhaps, caring for our children. Cellular phones have indeed allow people to do various tasks all at the same time. But while allowing people to efficiently multi-task and immediately reach and commu nicate with people, cellular phones have also marked a greater superficiality to the manner that people communicate today. However, communication is essential to keep any relationship stronger and to develop deeper connection with other people. Accordingly, it is better to have a close interaction or personal contact rather than

Gas Laws Lab Essay Example for Free

Gas Laws Lab Essay Introduction: In this lab we are going to investigate behavior of gas by working with a molecular model. Factors that effect gas behavior our pressure, temperature, volume and the number of moles. We are going to keep to variables constant and record the relationship or change in the remaining factors. Independent variables: Temperature, number of moles, volume Dependent variable: Pressure Controlled variable: apparatus used (computer program downloaded from the internet), volume and number of moles Question: What is the relationship between pressure and temperature of a gas filled container with constant volume and number of moles? Hypothesis: temperature and pressure are directly related. As temperature increases pressure increases. Pressure is directly proportional to temperature when the number of moles and volume are kept constant. Procedure: Log on to the Internet and visit heinnemann.co.uk/hotlinks and enter the express code 4266S. Click on weblink 3.2 the simulation on the right will appear. In this simulation one can set the parameters as per desire. For this experiment we need to set the volume and number of moles constant. Three trials are done for accuracy. For the first trial, we need to set the volume constant. The volume will remain set to the default value. Then pump 100 heavy species particle in the container and keep them the same until the next trial. The temperature will automatically go to 300K, remove heat to lower the temperature to 150K. Record the pressure produced. Add 50K each time, before taking another reading until the temperature reach 500K. Record the change in pressure with simultaneous temperature in a table. Before starting the next trail hit the reset button. Before starting the second trail change the depth of the container to 3.4nm. Measure the depth with a ruler (the ruler is given as a tool for measurement). Pump 100 more heavy species in the container to make a total of 200 particles. Increase the temperature as done before with similar intervals and record the pressure in form of a table. Hit the reset again and start the final trail. For the third trial, increase the depth of the container to 9nm and pump in a total of 300 heavy species particle. Record the temperature and pressure in a table. The uncertainty in this experiment for temperature is +0.5K and for pressure is +0.5 Pa. Use the tables to graph the data to show the relationship between temperature and pressure. Conclusion and Evaluation: From the data collected and the graphs processed we can make out that pressure is directly related to temperature when the number of moles of particles and the volume of the container is kept constant. We know that as temperature increases the particles gain more energy and collide at a faster rate with each other and the wall of the container. As the number of collisions increases, the more the particles exert force on the walls of the container. The force that the particles have on the walls is known as the pressure. All the 3 graphs have a linear relationship and the slopes of their lines are the coefficient of the temperature because temperature is directly related to pressure. As shown by the graphs temperature is directly proportional to pressure. In other words keep the volume and the amount of gas constant and change the temperature (by heating or cooling) and observe the change in pressure (Pressure law: P=const*T). The lines are not straight and a line of best fit is used. The unevenness of the lines on the graphs shows that there are slight errors involved in the experiment. The errors included are systematic, analytical and random. As the pressure was fluctuating the value noted was randomly chosen. The temperature was sometimes a point higher or lower, which again caused the pressure gauge to give a slight of value. Also the uncertainty in the measurement of volume showed that there were some errors also included while taking the measurement of the container. Suggestions for improvements: The lab was precise because of the number of trials done but it could be accurate by reducing the errors made in the experiment. Try to hit the raise the temperature of the container in the simulation accurately if that is not possible try setting the default temperature to the desired value and record the pressure. This would allow the pressure gauge to be more accurate. When taking measurement of the container for volume with a ruler try to avoid the parallax error, which is created by not looking at the measurement perpendicularly. Take the mode value from all of the values produced by the pressure gauge and wait a minute or two after setting the temperature and before noting the temperature. This helps to get a more accurate reading because the particles get enough time to settle. By recording the pressure value after giving certain breaks in the experiment will help the lines on all the three graph to be less uneven and more accurate.

Identity Crisis in Canadian Film Essay -- Canada Movie Movies Films es

Identity Crisis in Canadian Film Much has been written about the ways in which Canada's state as a nation is, as Peter Harcourt writes, "described" and hence, "imagined" (Harcourt, "The Canadian Nation -- An Unfinished Text", 6) through the cultural products that it produces. Harcourt's terms are justifiably elusive. The familiar concept of "Canadian culture", and hence Canadian cinema, within critical terminology is essentially based on the principle that the ideology of a national identity, supposedly limited by such tangible parameters as lines on a map, emerges from a common geographical and mythological experience among its people. The concept that cultural products produced in Canada will be somehow innately "Canadian" in form and content first presupposes the existence of such things as inherently Canadian qualities that can be observed. Second, it presupposes a certain commonality to all Canadian artists and posits them as vessels through which these said "inherently Canadian qualities" can naturally flow. T hird, it also assumes the loosely Lacanian principle that Canadian consumers of culture are predisposed to identify and enjoy the semiotic and mythological systems of their nation, and further connotes that Canadians have fair access to their own cultural products. Since these assumptions are indeed flawed but not altogether false, this paper will deal with the general relationship between the concept of Canada, its cultural texts, and its mythological and critical discourse as an unresolved problematic that should be left "open" in order to maximize the "meaning potential" of films as cultural texts within the context of "national identity," an ideological construct that remains constantly in flux. However pr... ...cate American entertainment films. But what was the cost to the development of Canada's supposed "cultural identity" and the perogative of the Canadian filmmaker to make a film without mimicking Classic Hollywood style and theme? Toward the mid-1980s, following the demise of the Capital Cost Allowance tax shelter in 1982, the "success" of a Canadian film was determined less by its forecast box office potential. The trend in the late 1970s and the early 1980s towards what Ted Magder calls the "If you can't beat `em join `em" (Magder, 169) relationship with the commercial Hollywood production infrastructure, was met in the mid-1980s by an equally vehement movement, which maintained that the infiltration of American culture and the adoption of their economic or "big-business" approach was precisely the problem with the Canadian film industry, and hence Canadian films.

Greendale Stadium Case

BONTE Geoffrey KERTESZ Samuel BONTE Geoffrey KERTESZ Samuel Professors  : Elisabeth KJELLSTROM Nikos MACHERIDIS Professors  : Elisabeth KJELLSTROM Nikos MACHERIDIS ASSIGNMENT 1: Essay on a case Greendale Stadium Case ASSIGNMENT 1: Essay on a case Greendale Stadium Case FEKH13 – Project Management A Business Perspective FEKH13 – Project Management A Business Perspective November 19 2012 November 19 2012 Questions 4th Edition of the book. 1. Will the project be able to be completed by the May 20 deadline? How long will it take? Yes, the project will be finished by March 27th 2009. That means 54 calendar days ahead of schedule.It takes 695 days to be completed. 2. What is the critical path for the project? There are two critical paths that share the same beginning and end. They differ from only two separate activities: * Clear Stadium Site => Drive Support Piles => Pour Lower Concrete Bowl => Pour Main Concourse => Install Seats => Construct Steel Canopy => Light Insta llation => Inspection. * Clear Stadium Site => Drive Support Piles => Pour Lower Concrete Bowl => Construct Upper Steel Bowl => Install Seats => Construct Steel Canopy => Light Installation => Inspection.If the total project time has to be reduced, the length of the critical path has to be shortened. The length of critical path is equal to the sum of durations of critical tasks. Here, it is equal to 695 days. Any delay of a critical task will delay the entire project. The essential technique for using CPM is to construct a model of the project that includes the following: * A list of all activities required to complete the project (typically categorized within a work breakdown structure), * The time (duration) that each activity will take to completion, * The dependencies between the activities. 3.Based on the schedule would you recommend that G&E pursue this contract? Why? Include a one page Gantt chart for the stadium schedule. Yes as the estimated completion date is March 27th 20 09. It is 54 calendar days ahead the deadline, 38 working days. It means that they have a buffer of 38 working days. Moreover, even if there are two critical paths, as mentioned they differed from only two separate activities. Finally, if too much delay occurs, weekend or over-time can be used to catch up. Defining the Project Project overview Project name: Greendale Baseball Stadium.

Restaurants and cafeterias’ furniture are not included in the contract. . Contractor responsible for subcontrac ted work 5. Site work limited to Monday through Friday, 8:00 am to 6:00 pm. The following holidays are observed: January 1st, Memorial Day, July 4th, Labor Day, Thanksgiving Day, December 25 and 26. F. Customer review Unknown, but it could be the city sportive commission. Step 2: Establishing the Project Priorities â€Å"Quality and the ultimate success of a project are traditionally defined as meeting and/or exceeding the expectations of the customer and/or upper management in terms of cost (budget), time (schedule), and performance (scope) of the project. A good trade-off has to be made among time, cost and performance. The objective of the project is a Baseball Stadium that we assumed has to last for at least 50 years. Thus project priorities are especially performance but also time as the stadium has to be finished before season start of 2009. Cost has to be taken into account, but doesn’t not represent the main focus within this project. Because of that, this project re present a risk for G&E as cost flexibility is really limited. | Time| Performance| Cost| Constraint| | | | Enhance| | | |Accept| | | | Figure 1: Project Priority Matrix Time: The schedule of the project has to be respected otherwise a penalty clause of $100,000 per day will be applied, which represents 5% of the estimated profits of the project. But it can be reduce. This is why it is a enhance priority. Performance: Performance of the project is fixed, they can’t be compromised and has to be respected. Cost: Going over budget is acceptable though not desirable, especially considering the small estimated profit in comparison of the size of the project.Step 3: Creating the Work Breakdown Structure The WBS is a map of the project, â€Å"it is an outline of the project with different levels of detail. † We divided it into 3 main points: 1. Initial planning and discussions with management team This category regroups the upper management decisions. It analyses the whole pro ject and selects a project manager as well as a team. 2. Project management activities This category regroups the middle management issues such as cost management, human resources managements, risk management†¦ 3. Building stadiumThis category specified in order the tasks needed for the construction of the stadium. They are the same as the ones used in the Gantt chart. REFERENCES Baker, S. (2004).

Jim Crow Essay

C. Vann Woodward’s book The Strange Career of Jim Crow is a close look at the struggles of the African American community from the time of Reconstruction to the Civil Rights Movement. The book portrays a scene where the Negroes are now free men after being slaves on the plantations and their adaptation to life as being seen as free yet inferior to the White race and their hundred year struggle of becoming equals in a community where they have always been seen as second class citizens. To really understand the motivation of C. Vann Woodward’s motives of his book, The Strange Career of Jim Crow, one must look at Mr.  Woodward’s life. Comer Vann Woodward was born and raised in Vanndale, AK in Cross County on November 13, 1908. The town was named after his mother’s aristocratic family. He attended Henderson- Brown College in Arkadelphia, AK for two years before transferring to Emory University in Atlanta, GA in 1930, where he graduated. He received his PHD in history at the University of North Carolina and after he took graduate classes at Columbia University where he was introduced and influenced by the Harlem Renaissance. Woodward taught at Johns Hopkins University from 1946-61 and at Yale University from 1961-67. He won the Pulitzer Prize in 1982 for Mary Chestnut’s Civil War and won the Bancroft Prize for Origins of the New South*. It was when he was teaching at Johns Hopkins when he wrote the book, The Strange Career of Jim Crow. It was during the court ruling of Brown vs Board of Education in 1954 that Woodward started his lectures, which lead to his book, at the University of Virginia. His audience was more or less surprised about the race relations of the old south during reconstruction; most thought that the two races have always been separated with hatred. Woodward argues that the Jim Crow laws of the 1890s were a new concept of separating the two races. Throughout slavery and during the reconstruction period, the two races were fully integrated working on economics and political problems; the separation of the two races would lead to an insufficient and ineffective plantation. â€Å"The typical dwelling of a slave-owning family was a walled compound shared by both master and slave families. Neither non-slaveholding whites nor free Negroes escaped this ntimacy, for they were ‘sprinkled through most parts of town and surrounded by people of both races’† (14). The same relations remained true during the Reconstruction era when the blacks started to urbanize in the south. Woodward goes on to say that the â€Å"blacks and whites lived side by side, sharing the same premises if not equal facilities and living constantly in each other’s presence† (14). The good relations of the south turned sour when conflicts between the whites over economic troubles heightened in the late 1870s. the determination of the Negro’s ‘place’ took shape gradually under the influence of economic and political conflicts among divided white people- conflicts that were eventually resolved in part at the expense of the Negro† (6). The Negro at the time became the scapegoat for all of America’s economic strife. Many thought it best if they separated themselves from the Negro then all would be better. Hence the Jim Crow laws started to form on the segregation of the two races and then court cases followed in suit, aka Plessy vs Ferguson in 1896 which ruled â€Å"separate but equal†. Ironically the south is known for the most racism but most cities were reluctant in to enforce legal separation of the races. In New Orleans, whites and blacks gathered freely at public events and even many had sexual relations with one another resulting in an influx of mulattos in that area (15-16). Racism did in fact take place in mostly rural areas. â€Å"An excessive squeamishness or fussiness about contact with Negroes was commonly identified as a lower class white attitude, while opposite attitude was popularly identified with ‘the quality’ (50). It was within these rural lower classes that extreme racism was formed involving white supremacy groups such as the Ku Klux Klan. As political parties started to shift in the mid 1880s, more conservative Democrats took the scene and strictly enforced the laws of segregation. The Republicans were the ones in support of more tolerant and equal society. The mentality of if one thing is separate then they all have to be took precedent during this time. With the shift of political parties, the segregation of the blacks from the whites heightened and the individual rights a Negro had were limited. Blacks were discouraged to vote and separation of the two races became almost total with separate modes of transportation to separate drinking fountains. After the Progressive era and the New Deal, integration was a thought in higher education. Colleges started to let Negro students attend white universities because the separation of the races at school was infringing on their fourteenth amendment rights (144). Even though theses students did not attend the university for all four years, it was progress that helped lead up to the 1954 case of Brown vs Board of Education. The school boards argued that â€Å"’Segregation of white and colored children in public schools has a detrimental effect on colored children’, for it ‘generates a feeling of inferiority as to their status in the community that may affect their hearts and minds in a way unlikely ever to be undone’† (147). The ruling of integration of public schools was monumental for the blacks at that time. After trying to fight racism and limitations of their individual rights, the blacks could finally be more equal then they had been in the eyes of the law. When Woodward presented his lectures at the University of Virginia, which subsequently led to his book, it was right after the ruling of Brown vs Board of Education. He insisted that his audience would be integrated as well so he spoke to not only students, faculty and dignitary of the university but he also spoke to local blacks and whites of the community. His lectures received mix reviews; some older, more conservative members of the university were shocked and appalled by Woodward’s comments of pro-integration, while others were intrigued. For them, the white Southern professor’s message was a challenge to the assumption that race relations had been immutably fixed over the course of Southern history† (224). Woodward also argued that the south was always changing and something that limited the rights of blacks in the 1890s was to turn around in the 1950s to something better. When The Strange Career of Jim Crow was released nationally, America did not agree with Woodward’s idea that it was time for a change, â€Å"segregation was ore firmly embraced than ever† (225). Whites did not approve of the ruling of the integration of schools so they protested and sometimes rioted when the government tried to integrate some of the schools. States such as Georgia put the confederate flag back on their state flag in defiance of the new laws (225). Blacks protested in comparison. After the arrest of Rosa Parks not wanting to give up her seat to a white man, the Civil Rights Movement launched its campaign of civil and equal liberties lead by Rev. Martin Luther King Jr. When this book was originally published in 1955, Rev King called it â€Å"the historical bible of the Civil Rights Movement†. I believe that the main reason behind King’s statement was that the movement was on the front page of every newspaper for over a decade that when the book did come out, Woodward looked at the struggle of the Negro in a historical sense and not putting blame on a specific race, but on certain decisions some legislators made that forced America to head in the direction of segregation. Woodward presented a historical and non threatening story which gave reason to the Civil Rights Movement. The blacks liked it because it showed the persecution they had to endure for so long and the perseverance they maintained throughout that time and the whites bought the book because it helped explain what was going on at that moment in time. No doubt that this book is an important historical document that helped a nation through one if its more difficult times in history.

Boiling Point Elevation Example Problem

Boiling Point Elevation Example Problem This example problem demonstrates how to calculate boiling point elevation caused by adding salt to water. When salt is added to water, the sodium chloride separates into sodium ions and chloride ions. The premise of boiling point elevation is that the added particles raise the temperature needed to bring water to its boiling point. The extra particles interfere with the interactions between solvent molecules (water, in this case). Boiling Point Elevation Problem 31.65 g of sodium chloride is added to 220.0 mL of water at 34  °C. How will this affect the boiling point of the water?Assume the sodium chloride completely dissociates in the water.Given: density of water at 35  °C 0.994 g/mLKb water 0.51  °C kg/molSolution:To find the temperature change elevation of a solvent by a solute, use the equation:ΔT iKbmwhereΔT Change in temperature in  °Ci van t Hoff factorKb molal boiling point elevation constant in  °C kg/molm molality of the solute in mol solute/kg solvent.Step 1 Calculate the molality of the NaClmolality (m) of NaCl moles of NaCl/kg waterFrom the periodic tableatomic mass Na 22.99atomic mass Cl 35.45moles of NaCl 31.65 g x 1 mol/(22.99 35.45)moles of NaCl 31.65 g x 1 mol/58.44 gmoles of NaCl 0.542 molkg water density x volumekg water 0.994 g/mL x 220 mL x 1 kg/1000 gkg water 0.219 kgmNaCl moles of NaCl/kg watermNaCl 0.542 mol/0.219 kgmNaCl 2.477 mol/kgStep 2 Determine the van t Hoff factorThe van t Hoff factor, i, is a constant associated with the amount of dissociation of the solute in the solvent. For substances which do not dissociate in water, such as sugar, i 1. For solutes that completely dissociate into two ions, i 2. For this example NaCl completely dissociates into the two ions, Na and Cl-. Therefore, i 2 for this example.Step 3 Find ΔTΔT iKbmΔT 2 x 0.51  °C kg/mol x 2.477 mol/kgΔT 2.53  °CAnswer:Adding 31.65 g of NaCl to 220.0 mL of water will raise the boiling point 2.53  °C. Boiling point elevation is a colligative property of matter. That is, it depends on the number of particles in a solution and not their chemical identity. Another important colligative property is freezing point depression.

Before we move to our next guide, how to write a cause and effect essay on evolutionary biology, take a look at the sample below, which has been written on one of the topics above: Cause and Effect Sample Essay: 7 Scientific Theories that Debunk Charles Darwin’s Evolutionary Theories Before the 1800s, scientists believed that the world we live in was created by a Master Designer, i.e. God. These scientists were hard workers and dedicated their life to researching and finding scientific facts about the origin of species. However, after the 1900s, philosophers who were rich and powerful, and had influence on society, suppressed those scientific endeavors in order to make their own hypotheses, just to make a name for themselves. William Paley, best known for his Natural Theology, explained that when we see the world, its complexity and how it works, it is clear that there is a Master Designer who has created this masterpiece. In fact, the â€Å"Argument of Design† states that it is unwise, and in some ways, foolish to think that anything at all might come into existence on its own. For example, if we see a watch, we know that it’s been crafted by someone who’s an expert in his/her field. The same goes for the universe; whoever made it must be a master at his craft. It’s a remarkable fact that Charles Darwin’s Evolution Theory was completely debunked even before it was published in his book, â€Å"The Origin of Species†. Carl Linn, one of the earnest creationists at the time, classified numerous species and during his scientific voyage, did not see any proof of ‘halfway species’. This is why he concluded that there were no crossover species, since every form of species are distinct and varied, even though there can be sub-species. However, he still maintained that it was impossible to have halfway species. The First Law of Thermodynamics is one of the most remarkable and highly respected theories today about the origins of the universe. This theory talks about the law of conservation of energy and how, no matter what size or shape, the amount of energy in a particular matter stays the same. This law clearly debunks several evolutionary theories that Charles Darwin had proposed – without scientific facts, it might be noted. The Second Law of Thermodynamics states the same and completely puts the basics of the evolutionary theory to rest, which is: simple evolves into complex. In the law of entropy, in plain words, everything runs down, wears out and is reduced to pieces. One of the most well-authenticated discoveries that also discredit the Evolution Theory is the discovery of a human skeleton in the French Caribbean island of Guadeloupe. This human skeleton dates back to 28 million years – estimated by modern geologists by determining the age of a slab of limestone, in which the skeleton was found. Modern human skeletons have also been found in the depths of the strata. Mendel was a great scientist and a creationist as well. For several years, he bred garden peas and did multiple researches to study the results of crossing various breeds. His work was completed in about eight years and when he revealed his findings, it was distributed among 120 renowned libraries around the world. However, his journal was rejected by the Scientific Society because it, in fact, went against the Evolutionary Theory. In conclusion, his work laid the foundation of modern genetics and revealed that there is a barrier between species that doesn’t allow them to transmute with one another. It was in the 1900s, when his research was discovered again and changed the world of modern genetics. Louis Pasteur was another great scientist who disproved the evolutionary basis: the spontaneous generation theory. This theory states that all living things came into existence from a nonliving material. The evidence behind this was that when a pile of clothes were to remain in a corner for a long time, they would breed mice! However, the reality was that mice would gather around that pile and nest in that place for comfort, warmth and perhaps, to feast on the clothes. Lamarckism, one of the strongest foundations of evolutionary theory, was also disproved by a German scientist, August Friedrich Leopold Weismann. To disprove â€Å"the inheritance of acquired characteristics†, he conducted an experiment on 901 young white mice by cutting off their tails. He did this 19 times (in every successive generation). However, each successive generation was born with a full-length tail. Yet, modern evolutionists still teach Lamarck today, in this modern day and age. Another fact that circumcision of Jewish people doesn’t affect growth on the foreskin put the theory of evolution into question and the legacy of Charles Darwin himself as well. There are a plethora of scientific facts that disprove evolutionary biology and point out that there is a Master Designer who has created this complex world we live in. Despite relying relentlessly on hypothesis with no scientific evidence or proof, our generation still studies evolutionary biology based on the origin of species that we see and perceive. This is utterly wrong and should be done away with completely – so that people can have a broader perspective in general and their researches, along with scientific facts they gather, lead to much more.
