Essay about Military - 1712 Words

Thank God for our military A Soldier, a Sailor an Airman and a Marine got into an argument about which service was the greatest. The arguing became so heated that they eventually ended up killing each other. Soon, they found themselves at the Pearly Gates of Heaven They meet St Peter and decided that only he would be the ultimate source of truth and honesty, so they osked him: quot;St Peter which branch of the American Armed Forces is the best?quot; St. Peter instantly replied: quot;I cant answer that. But I will ask God what he thinks next time I see him. Some time later, the four saw St. Peter again and reminded him of the question and asked if he was able to get an answer.

The Effects Of War On Post Traumatic Stress Disorder

Veterans make up 7.3 percent of living Americans or about 22 million individuals and .4 percent are currently active duty according to Veteran Affairs data(2014). 3.9 million are current day veterans of Operation Iraqi Freedom/ Enduring Freedom. Veterans are a minority within our country but have a much higher prevalence for substance abuse disorder and post traumatic stress disorder. The direct psychological impact of war can be seen especially in veterans of Operation Iraqi Freedom and Enduring Freedom.

One third of veterans with PTSD will not receive the proper care or treatment and and a disturbing amount of 84 percent of veterans will not have their needs met in the treatment of AUD. This makes you wonder what the VA is really taking care of as this is the biggest health issue concern among veterans. Why does Veterans Affairs ignore the fact that AUD is one of the leading causes of suicide? There are 22 veteran suicides completed on a daily basis and this number is smaller than the true number as this is from veterans who are actually registered in the Veteran Affairs health system (Subhajit Chakravorty et al. 2014). The following are the leading factors leading to veteran suicide: The use of drugs and alcohol, male, white, married or separated, and having an mental health disorder. With the high risk factor for alcohol abuse you can correlate that it is related to suicide through a study that involved approximately 300 veterans who were being seen for depre ssion and who eventually completed suicide. These cases all involved alcohol dependencies as a severe risk factor (Subhajit Chakravorty et al. 2014). A huge risk factor caused by alcohol is the development of insomnia.

Analysis of Act 3 of A Dolls House Essay - 661 Words

Analysis of Act 3 of A Dolls House For most of the play, we see Torvald delighting in Nora’s dependence upon him but not in his control over her, but as the play progresses the side of Torvald we see is more pushover than dictator. In the scene following the party, Torvald’s enjoyment of his control over Nora takes on a darker tone. He treats her like his possession, like the young girl he first acquired years ago. Contributing to the feeling of control that Torvald is exercising over Nora is that the evening has been of Torvald’s design—he dresses Nora in a costume of his choosing and coaches her to dance the tarantella in the manner that he finds â€Å"desirable.† The hollowness of Torvald’s promises to save Nora shows how†¦show more content†¦He panics upon learning of Nora’s crime, not because he cares about what will happen to her but because he worries that his reputation will be damaged if knowledge of Nora’s crime becomes public. Instead of treating Nora with understanding and gratitude for her noble intent, he threatens and blames her and then immediately begins to think of ways to cover up the shame that she has cast on his family. His proclamation of â€Å"I’m saved† after Krogstad’s letter of retraction arrives reflects that he has been thinking only of himself in his panic. He says nothing about Nora until she asks, â€Å"And me?† His casual response—â€Å"You too, naturally†Ã¢â‚¬â€reveals how much her well-being is an afterthought to him. Torvald’s selfish reaction to Krogstad’s letter opens Nora’s eyes to the truth about her relationship with Torvald and leads her to rearrange her priorities and her course of action. Her shift from thinking about suicide to deciding to walk out on Torvald reflects an increased independence and sense of self. Whereas she earlier she succumbs pressure from Torvald to preserve the appearance of idealized family life, she now realizes that she can exist outside Torvald’s confined realm. Torvald’s explanation for refusing to take the blame—that a man can never sacrifice his integrity for love—again reveals the depth of his gender bias. Nora’s response thatShow MoreRelatedAn Analysis Of Henrik Ibsen s A Doll s House 970 Words   |  4 PagesA Doll’s House Ashleen Kaushal TOPIC: The theme of heredity in the play I.

Amino Acid Chromatography Free Essays

In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. We will write a custom essay sample on Amino Acid Chromatography or any similar topic only for you Order Now Introduction Proteins in cells are important in many ways. There are different types of proteins such as contractile proteins, enzymes, hormonal proteins, structural proteins and transport proteins. They are vital to regular cell functioning. Proteins are made up of amino acids that are joined together by peptide bonds. When fewer than 50 amino acids are joined together, a polypeptide is formed. All proteins have two groups in common. They have a carboxylic group and an amino group. There are 20 types of amino acids that bond together in different combinations to perform different functions. The primary structure of proteins is the order and number of amino acids. Secondary, tertiary and quarternary structures are formed from chains of peptides that are folded into sheets, ribbons and coils so that they form a 3D shape and are more stable. Different weights of amino acid make them differ in polarity. This characteristic enables the separation of proteins by polarity using chromatography. Paper chromatography is an example of a chromatography technique called absorption chromatography. The paper is the adsorbent, which will bind the components of the mixture. The substance will be â€Å"spotted† onto the chromatography paper and put into a beaker filled with solvent. The solvent will then flow through the paper. The solvent chosen depends highly on its polarity as this will be the characteristic that will separate the different substances. Petroleum, ether, hexanes, cyclohexanes and toluene are some examples of solvents with different polarities as well as increasing polarities. In some cases, mixtures of solvents are made to reach a certain polarity. If substances that are needed to be separated are polar, then the solvent must be slightly less polar. Non-polar substances need a polar solvent to be separated. The solvent travels faster than the samples. The Rf value is the ratio of the distance traveled by the sample and the distance travelled by the sample. Rf = distance travelled by amino acid sample from the origin in mm distance travelled by the solvent from the origin in mm Factors affecting how far the amino acids travel depend on how high the solvent is allowed to rise on the paper, the type of absorbent, the type of concentration of the solvent, temperature and the distance of the origin from the solvent. One type of test to detect proteins is the Ninhydrin test. This test makes the amino acids spots visible. Ninhydrin is a pale yellow solid and it reacts with the amino group in the amino acids and proteins and produces a purple product. Heat must be used in order to speed up the reaction. Objective The objective of this experiment was to spot various amino acids and an unknown mixture on chromatography paper and run it with a chromatography solvent. The lab period following included treating the samples with Ninhydrin solution and heating it so that the amino acids could be visible. The distance of the samples were then measured in mm from the origin. The measurements were then used to calculate the Rf values for each sample and thus the unknown sample could be identified. Materials Alanine, 1% Solution Arginine, 1% Solution Asparagine, 1% Solution Aspartic acid, 1% Solution Glycine, 1% Solution Lysine, 1% Solution Methionine, 1% Solution Tyrosine, 1% Solution Unknown, 1% Solution Chromatography Solvent, 20mL Ninhydrin solution, 2%, 10mL Beaker, 600mL Chromatography paper, 20X10 cm Graduated Cylinder, 25-mL Heat source, drying over or hot plate Microtip pipets, 9 Pencil Ruler Spray bottle Stapler Watch glass or aluminum foil Procedure 1. On a 20cm wide by 10 cm high piece of chromatography paper, a pencil was used to draw a straight line (about 1 cm) from the bottom of the paper from the left to the right side 2. Nine pencil dots were placed 2cm apart on the line 3. The name of each amino acid was written under each dot in pencil. 20 mL of chromatography solvent was then added to the 600-mL beaker 4. A micropipette was used to obtain a small amount of the first amino acid 5. The tip of the pipette was placed above the chromatography paper directly above the pencil dot and a spot of the amino acid was dropped on the dot 6. Steps 4 and 5 were repeated for the eight amino acid solutions 7. With the sample side facing outwards the chromatography paper was turned into a cylinder and the top and bottom edges of the paper were stapled. . The paper cylinder was then placed into a beaker with the chromatography solvent. 9. The beaker was then covered with a watch glass 10. The samples were then allowed to run till the solvent level was about 1 cm from the top of the paper. 11. The chromatography paper was then removed from the beaker. The solvent height was then marked with a pencil line and the staples were removed 12. The chromatography paper was then left to dry During the following lab 13. The chromatography paper was sprayed with a spray bottle containing 10mL of 2 % Ninhydrin solution 14. The chromatography paper was left to dry for 10-20 minutes 15. The paper was then put in a drying oven or held 10 cm above a hot plate to heat so that the color could develop 16. A dot was placed with a pencil at the centermost point of each amino acid 17. The distance in mm of the solvent traveled from the pencil line till the where the solved stopped traveling was measured. 18. The distance in mm from the origin till where each amino acid traveled was measured 19. The Rf value for each amino acid was calculated Results Table 1: Distance and Rf values of the amino acids and unknowns Amino Distance(mm)452427223015574235/60 Rf Value0. 50. 270. 30. 240. 330. 170. 630. 470. 39/0. 67 The distance traveled by the solvent from the pencil line drawn was 90mm. The unknown samples were found to be Glycine and Methionine by comparing their Rf and distances values to those amino acids with Rf and distance values that were calculated. Discussion Paper Chromatography is used to separate a mixture of compounds into its components. Pens and markers are not used as their ink will be separated too. Instead, pencils are utilized as they are made from graphite which does not separate. Capillary action is the ability of a liquid to flow in narrow spaces without any help from external forces. This flow is against gravity as well. This happens because of the intermolecular attractive forces between the liquid and the solid surrounding surfaces. Surface tension and adhesive forces between the liquid and solid also help the liquid rise through the solid. The Rf value is defined as the ratio of the distance travelled by the amino acid sample from the origin to the distance travelled by the solvent. The ratios, therefore, stay the same regardless of the solvent used. Ninhydrin is used in paper chromatography to identify amino acids. Ninhydrin solution turns the amino acid fingerprints to the color purple, therefore making them visible. For this reason we take care when touching the chromatography paper. The least polar amino acid was alanine as the distance it moved up the paper was the least. How to cite Amino Acid Chromatography, Papers
