An Old Assyrian Proverb By Marquis De Lafayette - 1894 Words

An old Assyrian proverb states â€Å"tell me your friends, and I’ll tell you who you are†, but what does that say about you when you’re friends with the great George Washington? Does it mean that you yourself are also a great man? That is what it truly seems to mean when it comes to Marquis de Lafayette. Lafayette was the top-ranking officer to the commanding general George Washington, and a very huge contributor to the United States of America gaining its independence. Marquis de Lafayette was born on September 6, 1757, in Chavaniac, in the province of Auvergne in south central France. By the age of two Marquis lost his father who was a Colonel of grenadiers when he was killed at the battle of Minden in 1759 during the seven years’ war. Nine years after his father’s death in 1768, he moved to Paris with his mother, and entered the college du Plessis. By the age of 12 Marquis became an orphan when his mother passed away as well. His grandmother pass ed not long after his mother as well, leaving Marquis with a large inheritance. On April 9, 1771, When Lafayette was fourteen years old he entered the Royal Army. Two years later when he reached the age of sixteen, Lafayette married Marie Adrienne Francoise de Noailles. This gave him an alliance with one of the top and most wealthy families in France since she was related to the king. Lafayette was introduced to America at a dinner on August 8, 1775. The Duke of Gloucester spoke with him of the struggles going on in the colonies

The Role of Science in Our Life

The Role of Science in Our Life In every generation and in every century there always exist a number of people, who are afraid of everything that is related to possible changes. In various epochs they are called differently: luddites, anti-globalists, ecologists and so on; but their nature is always the same. They hate progress and strive to preserve the status quo without seemingly realizing the fact that the same very kind of people hated progress and strived to retain the status quo a hundred years ago, and now they use all the things that were denounced by their spiritual ancestors. In their blogs on the Internet they write about immoral scientists, who conduct dangerous experiments; but they do not realize that they actually use the product of the very science they hate in order to convey their thought to the similarly-minded. Science always has to fight against heavy odds, for it always tries to show how useful something may be to people who don’t want to listen, knowing that the very moment they will be persuaded, they will use a yet another product of science against what has created it. It wouldn’t be an exaggeration to say that a scientist is the hero of modern day, and not a politician or a social activist. Science makes our life possible – today a human being cannot imagine his or her life without all the many thousands of little and big things, created by science in the course of millennia. And the people who denounce it for meddling with the things that we do not understand, just don’t see that there is no way to study a thing that you don’t understand without, well, studying it. Of course, science always prevails in the end, for life is stronger than death. But it is really embarrassing to see how hard it has to fight.

Process Writing for ESL and EFL

Process writing is an approach to incorporating writing skills from the very beginning of the English learning process. It was developed by Gail Heald-Taylor in her book Whole Language Strategies for ESL Students. Process writing focuses on allowing students—especially young learners—to write with plenty of room left for error. Standard correction begins slowly, and children are encouraged to communicate through writing, despite limited understanding of structure. Process writing can also be used in an adult ESL/EFL setting to encourage learners to start working on their writing skills from a beginning level. If you are teaching adults, the first thing learners need to understand is that their writing skills will be well below their native language writing skills. This seems rather obvious, but adults are often hesitant to produce written or spoken work that is not up to the same level as their native language skills. By easing your students fears about producing sub-par written work, you can help encourage them to improve their writing abilities. Only mistakes made in grammar and vocabulary that has been covered up to the current point in time should be corrected. Process writing is all about the process of writing. Students are striving to come to terms with writing in English by writing in English. Allowing for mistakes and refining based on materials covered in class—instead of perfect English—will help students incorporate skills at a natural pace, and improve their understanding of materials discussed in class in a natural progression. Here is a short overview of how you can incorporate process writing into your students learning routine. Aim: Improve writing skills from beginning levels of EnglishActivity: Process writing - journalsLevel: Beginning to advancedMaterials Needed: Notebook for each student Outline Encourage learners to write in their journal at least a few times a week. Explain the idea of process writing, and how mistakes arent important at this stage. If you are teaching higher levels, you can vary this by stating that mistakes in grammar and syntax on material not yet covered arent important  and that this will be a great way to review material covered in past levels. Students should write on the front side of each page only. Teachers will provide notes on the writing on the back. Remember to focus only on material covered in class when correctly student work. Start this activity by modeling the first journal entry as a class. Ask students to come up with various themes that could be covered in a journal (hobbies, work-related themes, observations of family and friends, etc.). Write these themes on the board. Ask each student to choose a theme and write a short journal entry based on this theme. If students do not know a particular vocabulary item, they should be encouraged to describe this item (for example, the thing which turns on the TV)  or draw the item. Collect the journals the first time in class and do a quick, superficial correction of each students journal. Ask students to rewrite their work based on your comments. After this first session, collect students workbooks once a week and correct only one piece of their writing. Ask students to rewrite this piece.

Symptoms Of Alzheimer s Disease - 2043 Words

Introduction I think one of the saddest day in my life was when I found out my father had Alzheimer’s disease. It took an emotional toll on me and my family members. I believe Alzheimer is much harder on me and my loved ones than on my grandfather; because he was unaware of what was going on. It’s painful watching my grandfather degrade and get worse each and every day. The worst thing is that he doesn’t even know who I am anymore. In this paper I will discuss certain risk factors, background of Alzheimer’s, Background of Alzheimer’s Alzheimer’s disease was first identified in 1906 by German doctor Alois Alzheimer and was named after him. Alzheimer s disease (AD) is a neurodegenerative disorder associated with aging and characterized by deposits of beta-amyloids and neurofibrillary tangles. Alzheimer’s disease disrupts the critical metabolic processes in neurons and makes them unhealthy. Due to these disruptions the nerve cells lose connections with other nerve cells, stop working and finally die. The death of nerve cells in temporoparietal cortex and frontal cortex is the primary reason for memory failure, personality changes, and problems in carrying out daily activities. According to the Associated Press† Smokers are twice as likely as lifetime nonsmokers to develop Alzheimer’s disease and other forms of dementia†. What causes Alzheimer’s?

Study of Hematology and Blood Free Essays

string(50) " can be converted to SI units by diving into 100\." INTRODUCTION Blood is a red syrupy fluid that is thicker than water. It carries out the important functions of transporting oxygen and getting rid of carbon-dioxide and other waste products as well as transporting nutrients to our cells. And it also plays a crucial function in immune system and in maintaining a relatively constant body temperature. We will write a custom essay sample on Study of Hematology and Blood or any similar topic only for you Order Now Blood is a tissue that is composed of many different kinds of components. Blood is composed of cells, cellular fragments and fluid. And these are red blood cells, white blood cells, platelets and plasma. http://www.ich.ucl.ac.uk/factsheets/families/F030004/ Red blood cells (erythrocytes) are cells with no nuclei. They appear relatively large under microscope. These cells are similar to the primitive prokaryotic cells of bacteria. Red blood cells transport oxygen from the lungs to all of the living tissues of the body and carry away carbon-dioxide. ‘’The red blood cells are produced continuously in the bone marrow from stem cells at a rate of about 2-3 million cells per second’’ (O’Neil, 2007). White blood cells (leucocytes) are much larger than red blood cells, but it is able to change its shape so it can squeeze through little gaps. White blood cells contain nucleus and has colourless cytoplasm. They are involved in protection from bacteria, fungi, parasites and viruses. These cells are formed in the white bone marrow of the long bones. White blood cells have five types (each cell has a task in helping the body fight infections): Granulocytes: Neutrophils (engulf bacteria) Eosinophils (antihistamine properties) Basophils (produce histamine and heparin) Agranulocytes: Monocytes (engulf bacteria) Lymphocytes (produce antibodies) (Fullick, A., 1994, p.142) Platelets (thrombocytes) are cell parts with no nuclei. It releases blood clotting chemicals at the site of wounds. Platelets are fragments of a larger cell called megakaryocyte, which stays in the bone marrow after it differentiates and matures from the stem cell. The platelets circulate body after leaving the bone marrow. Platelets contain high concentrations of 5-Ht (G-protein linked receptors), which is not synthesized inside the platelets but is actively absorbed from the circulation by specific uptake mechanisms. 5-HT is stored in secretor granules and discharged during platelet aggregation in reaction to endothelial damage. 5-HT causes a direct local constrictor effect as well as an increase in platelet aggregation, thereby encourages haemostasis. Haemostasis is a vital defence mechanism aimed at minimizing blood loss during injury. There are billions of living blood cells in human body that are floating in liquid called plasma. The plasma is a mixture of water, sugar, fat, protein, potassium, calcium salts and many other chemicals that help for clotting when necessary to stop bleeding. More than 92% of plasma is water. As the heart pumps blood to cells throughout the body, plasma brings nourishment to them and also removes the waste products of metabolism. The layers of blood cells can be seen under the microscope, once it is centrifuged. This machine spins the blood around so fast that it separates the red blood cells from the white blood cells and from platelets. In this process the red blood cells sink to the bottom as they are heavier and have more solid parts. Therefore the plasma remains right at the top, as it is lighter. (Genetic science learning centre, 2008) http://www.uwosh.edu/med_tech/teaching/ElementaryHemeWeb/LEARN%20ABOUT%20RBCS%20AND%20PLTS.htm When clotted blood is centrifuged to separate the cellular components a fluid is formed, called serum. The difference between plasma and serum is that the latter lacks fibrinogen and some of the coagulation factors. Fibrinogen is an important blood protein made in the liver and it is involved in clotting. Fibrinogen is transformed into fibrin by an enzyme called thrombin. And this enzyme is essential to coagulation. Coagulation is to prevent excessive blood loss. A clot is composed of two elements, which are platelets and fibrin. Blood coagulation takes place due to the sequential conversion of series of inactive proteins into catalytically active protease enzymes. Anticoagulants correspond to important therapeutic agents in the management of thromboembolic disease. (Blann, 2007; Lewis, 2006). http://faculty.ccri.edu/kamontgomery/physiology%20blood.htm The main purpose of the Haematology Laboratory is to provide assistance in the diagnosis, monitoring and treatment of patients. To accomplish this, the components of the blood are analysed. This is almost always achieved in custom-designed equipment. All the blood tubes and forms must be fully labelled to avoid any possible fatal error. Caution needs to be taken when dealing with the blood samples and all laboratory rules must be applied. Red blood cells contain a special protein called Haemoglobin (Hb), which is responsible for making red blood cells red. Hb is a protein that is premeditated to carry oxygen from the lungs to the tissues; this is where the oxygen is given up to take part in respiration. The standard range of Hb in blood differs between sexual categories. Hb values for women are lower due to menstruating and higher for men. But even when the women are in post-menopausal period, the Hb levels are still lower than age-matched men. This is because the latter produce testosterone to stimulate red cell production. ‘’ The red blood cell count (RCC): Normal range in men 4.32 to 5.66x 1012/L, in women 3.88 to 4.99?1012/L.’’ (Blann, 2007. p.8). The amount of Hb in blood could be measured in following conversion to azidmethaemoglobin by the addition of sodium nitrate and sodium azide. This is a method employed by one portable haemoglobinometer (HemoCue, Clandon Scientific Ltd.)- This instrument only measures Hb. It takes up measurements at two wavelengths, which are 570nm and 880nm to compensation for turbidity. The reading of the haemoglobin content of the sample is measured in gram/litre blood. A modification of this instrument permits accurate measurements down to 0.1 g/L so that it is also suitable for measurement of dilute solutions of haemoglobin, e.g. haemoglobin in fluid salvaged during surgery, plasma or urine. (Bain, 2002, p. 18). Haematocrit is known as packed cell volume (PVC) or Hct, Crit. This is a count to calculate the whole blood that is taken up by all the blood cells. Haematocrit is measured in percentage and can be converted to SI units by diving into 100. You read "Study of Hematology and Blood" in category "Essay examples" The red blood cell indices are mean cell volume (MCV), mean cell haemoglobin (MCH) and mean cell haemoglobin concentration (MCHC). MCV is the size of the average (mean) red blood cell. MCV can be calculated by; PCV?RCC. MCH reports the average amount (mass) of haemoglobin in the average cell. The size of the cell is not taken into account. MCH can be calculated by; Hb?RCC. MCHC is the average concentration of haemoglobin inside the average size cell. MCHC can be calculated by Hb?Hct. Aim is to study rat blood sample given to us. Therefore count the visible red blood cells under microscope at high power using Neubauer Chamber. Following this count of red blood cells calculations will be applied in which it will determine the haematology of the provided rat blood sample.

The difference has been recorded above (Table 2). The standard values and all the units are included in the table. As seen in Table 2; some values obtained are not within the rat reference range; this was expected as these values are compared to the human reference range values. Values are different between sexual categories, apart from the values for red blood cell indices (MCV, MCH and MCHC). These values will be discussed in the discussion. To obtain red blood cell indices (MCV, MCH and MCHC), series of calculations have been made; these calculations are shown step by step in the calculations section. Reference range values were taken from ‘Haematology Proforma’ booklet given during the experiment. Calculations Red cell count (RCC) The number of erythrocytes counted in 80 small sequences on the Neubauer haemocytometer is 864. Multiplying this value by 1010 will give the number of erythrocytes in one litre of blood: 864?1010 = 8.64x 1012 /l This RCC value is higher than an average value of standard human haematological indices. The standard value of human haematological indices for male is 3.5-6.0?1012/l and for female is 3.5-5.5?1012. The RCC value is within the average value for standard rat haematological indices. The standard value of rat haematological indices is 6.76-9.75?1012/l. Haematocrit (PCV) The percentage of a blood sample occupied by erythrocytes after centrifugation in a capillary tube is 49%. Hct= (distance of red blood cell collected in the centrifuge tube ? distance of total blood composition) x 100 This value can be converted into SI units, dividing by 100: 49(%) ? 100= 0.49 l/ The PVC value is within the normal range of value for human males and females. The standard value of PVC for male is 0.35-0.55 l/l and for female is 0.30-0.50 l/l. The PVC value is also within the normal range of values for rats. The standard value of PVC for rat is 0.38-0.51 l/l. Haemoglobin (Hb) content of a blood sample using ‘Hemocue’ haemoglobinmeter The recorded Hb content is 178 g/l of blood. The value recorded for Hb content of blood is within the standard value for human blood. The standard value of Hb content for human blood for male is 135-180g/l and for female is 115/165g/l. The value recorded for Hb content of blood is above the standard value for rats. The standard value of Hb content for rat blood is 115-161g/l. Mean Cell Volume (MCV) MCV = PCV?RCC = n x1012 x1000= y x1015 MCV is in 1015 so therefore this value needs to be multiplied by 1000. 0.49?8.64= 0.057?1012 0.057?1000=57 x1015 MCV= 57fl The MCV value is lower than the normal range of values for human males and females. The standard values of MCV for human male and female are 80-96fl. The MCV value is lower than the normal range of values for rats. The standard value of MCV for rats is 69-85fl. Mean Cell Haemoglobin (MCH) MCH= Hb?RCC 178?8.64= 20.60pg (2d.p.) MCH= 20.6 pg The MCH value is lower than the normal range of values for human male and females. The standard value of MCH for human male and female are 27-32pg. The MCH value is lower than the normal range of values for rats. The standard value of MCH for rats is 24-30pg. Mean Corpuscular Haemoglobin Concentration (MCHC) MCHC= Hb?Hct 178?0.49= 363.27g/l (2d.p.) MCHC= 363.27 g/l The MCHC value is higher than the normal range of values for human male and female. The standard value of MCHC for human male and female are 320-360g/l. The MCHC value is higher than the normal range of values for rats. The standard value of MCHC for rats is 320-360g/l. DISCUSSIO The value obtained from rat blood sample for red cell count (RCC) is within the range in rat reference range. The value obtained for Hb is 8.64?1012/l. When this value is compared to the human reference range, it is higher. RCC differs between the sexual categories, reference range for human male is between 3.5-6.0?1012/l and for human female is 3.5-5.5?1012/l. So therefore the RCC value obtained for rat blood sample is closer to the human male reference range than female reference range. The standard RCC of rat blood is much higher than human’s standard RCC. So the results obtained for RCC is accurate. The value obtained from rat blood sample for determination of haemoglobin (Hb) is higher than the expected value. The value obtained for Hb is 178 g/l/. So therefore the obtained value is 17g/l higher than the maximum reference range for rats. This could be because of an operator error whilst filling round the chamber, or while removing the excess blood and place in haemoglobinmeter. The other source of error could be rat blood sample used. It might have had different Hb values from the rest. When this value is compared to the reference range of human values, noticed that obtained values are closer to the standard Hb of human values. Hb values differ between sexual categories; reference range for human male is between 135-180 g/l and for human female is115-165 g/l. So therefore the values obtained from rat blood sample are within the range in reference range value of human male and for female it is 13 g/l higher from the maximum reference range of female. The value obtained from rat blood sample for determination of haematocrit (PVC) is within the range in rat reference range. The value obtained for PVC is 0.49 l/l. This value has been converted to SI units from the percentage number. It has been converted by dividing the percentage number into 100. This value is also compared with the human reference range, both for male and female. The reference range value for human male is 0.35-0.55 l/l and for human female is 0.3-0.5 l/l. the value obtained for PVC from rat blood sample is within the range of human male and female reference range a value. Mean cell volume (MCV) value is obtained by the values already obtained for PCV and RCC. So therefore MCV value varies due to these values. The value obtained from rat blood sample for MCV is lower by 12fl of the minimum range value. The value obtained for MCV is 57fl; this value has been gained after a series of calculations. The value of MCV is lower than the reference range for rats (69-85fl). This could be because the PVC value obtained is lower than the expected or the RCC value is bigger than the expected value. As the RCC value increases the MCV value decreases and as PCV increases the MCV value increases. When the value obtained from rat blood sample for MCV is compared to the reference range of human values (in this case the values are the same for male and female), it is lower by 23fl from the minimum value. Mean cell haemoglobin (MCH) value is obtained by the values already obtained for Hb and RCC. So therefore MCH value varies due to these values. The value obtained from rat blood sample for MCH is lower by 3.4pg of the minimum range value. The value obtained for MCH is 20.6pg, where as the reference range value for rat is 24-30pg. This could have been because the Hb value obtained is low for the calculation, but the Hb value is already higher than the reference range value. And RCC is within the range so the expected value for MCH was higher than the reference range. This inaccurate value could be a result of the RCC value being close to the maximum value. If this value was a bit lower, the MCH value would be in the range or closer to the reference range of rat. When the value obtained from rat blood sample for MCHC is compared to the reference range of human values (in this case male and female values are the same), it is lower by 6.4pg of the minimum range value. Mean cell haemoglobin concentration (MCHC) value is obtained by the values already obtained for Hb and Hct. So therefore MCHC value varies due to these values. The reference range numbers for rat and human (male and female) values are all the same with each other. The value obtained from rat blood sample for MCHC is lower by 3.27 g/l of the maximum range value (for human and rat). As the Hb value increase, the MCHC values increases too and as the Hct value increases, the MCHC value decreases. Hct value is already within the range, so therefore Hb value is the in accurate result. Hb value needs to be the nearest to the maximum value, so that the MCHC value would be in the range. The values calculated for red blood cell indices (MCV, MCH and MCHC) from rat blood sample are not within the range. So this means that the results obtained are not accurate. The values obtained for RCC and PVC/Hct from rat blood sample is within the range of rat reference range. But Hb value is higher than the maximum range value. This could be because of an operator error in poor pipetting technique or poor counting technique Strong dilution of sample could result in inadequate results. As seen on the Table1 RCC and PVC/Hct values are very close to the maximum of reference range value, and Hb value is higher than the maximum of reference range value.

Represent a Democratic Revolt of the People free essay sample

In the Election of 1824, Jackson had the most popular and electoral votes, but did not win the election. Because the vote was split four Ways, he did not have the majority Of the Electoral College and John Quince Adam became president. Jackson supporters believed that voters were told to vote for Adams or Clay through secret political maneuvers. They accused them of making a corrupt bargain. Adams and Jackson both ran for president again in the Election of 1 828, which was also known as a revolution. Jackson and his followers had a new campaign tactic, which was accusing Adams wife of being born out of wedlock. Adams accused Jacksons wife of adultery. This election attracted a lot of interest and had three times as many voters as the Election of 1824. Jackson won and became president in 1829. During his presidency, Andrew Jackson gave all men the opportunity to hold government jobs. This is why this period is called the Age of the Common Man. Before Jackson became president, rich southern planters and northern merchants dominated the government. Now, under Jacksons rule, white males of the lower and middle classes began to vote in large numbers. There were new state suffrage laws, which enabled more citizens to vote, due to deter education, changes in political parties, and an increase in newspaper circulation. Western states also adopted these laws, which were called Universal male suffrage. All white males from one end of the country to the other were allowed to vote regardless of their religion or social class, and could hold government jobs, even if they were in the middle or lower classes. Also, voters and politicians now nominated candidates, rather than the political party leaders in Congress.This and other events led to a more democratic society. Jackson also gave government jobs to regular people. This was called the spoils system. He appointed people to federal jobs depending on whether they had campaigned for the Democratic Party. Anyone currently in office who was not a democratic was replaced with a democrat. This was called the spoils system because it promoted a corrupt government. He also believed in rotation in office. He wanted to make it possible for more democrats to have government jobs, so he limited a persons time in office to one term.The spoils system showed how one man was no better than another and helped build a strong two-party system. In the two-party system, supporters of Jackson were Democrats and supporters of his rival, Henry Clay, were the Whig. The Democratic Party resembled the old Republican party of Jefferson, while the Whig represented the Federalist party of Hamilton. Jackson was similar to Jefferson because he opposed increasing federal spending and the national bank. He vetoed 12 bills, which was more than the total of all 6 presidents before him.One of the things he vetoed was the use of federal money to make the Massively Road, because it was entirely in one state. It was also the home state of Henry Clay, Jacksons rival. Jackson also aided the common woman. Peggy ONeal Eaton, the wife of Jacksons secretary of war, was gossiped about by other cabinet wives. They didnt invite her to parties because they believed she was an adulteress. Most of the cabinet resigned when Jackson tried to force their wives to accept Peggy Eaton. Because of this controversy, Jacksons vice president, John C.Calhoun, resigned and Martin Van Burden was chosen to be the new vice president. Jackson disliked Native Americans and agreed with citizens who wanted to take over lands previously owned by them. Jackson decided to make the Indians leave their homelands and settle west of the Mississippi. In 1830, he signed the Indian Removal Act. This forced thousands of Native Americans to resettle. When Georgia passed laws that required the Cherokees to move to the west, they were challenged in the courts. The court cases were Cherokee Nation v. Georgia and Worcester v.Georgia. In 1838, after Jackson left office, the U. S. Army forced the Cherokees to leave Georgia. This was called the trail of tears. Jackson favored states rights if it didnt lead to disunion. In 1828, when South Carolina called the Tariff of Abominations unconstitutional, the nullification theory was created, in which each State could declare a federal away null and void. Not only did South Carolina nullify the tariff of 1 828, but it also nullified another tariff in 1832. The collection of tariffs within South Carolina was forbidden.Jackson told the secretary of war to prepare for military action and persuaded Congress to pass a Force bill giving the president the authority to take military action. In his Proclamation to the People of South Carolina, he stated that nullification and disunion were treason. Jackson gave the opportunity for a compromise by suggesting the lowering of the tariff. South Carolina postponed nullification and Jackson arced militant advocates of states rights to retreat. He also gained southern support because he shared their alarm of a growing antislavery movement in the North.Citizens of the South trusted that Jackson would not give the benefits of democracy to blacks. Another issue that Jackson dealt with during his presidency was the recharging of the Bank of the U. S. Jackson had the suspicion that Nicholas Fiddle, the banks president, abused the banks powers and served the interests of the wealthy. Jackson felt that it was unconstitutional. In 1832, Clay decided to challenge Jackson, by persuading Congress to pass bank-recharge bill. Jackson vetoed the bill because it helped the wealthy at the expense of the common people.
