Comparing The Us Constitution :: essays research papers

In 1918, while the rest of Europe was still engaged in World War I, a newly formed communist government was developing in Russia. Much like 18th century Americans, they had just managed to overthrow what was viewed as a tyrannical government and hoped to form a new nation free of the injustices of the previous rule. Both countries wrote a new constitution as well as a declaration of rights to facilitate this, but their respective documents had vast differences. These disparities stemmed from differences in the ideologies of the new governments. The primary objectives of the Russian Declaration of Rights of the Working and Exploited People and the later constitution were the â€Å"abolition of all exploitation of man by man, complete elimination of the division of society into classes, merciless suppression of the exploiters, socialist organization of society, and victory of socialism in all countries.† Americans wanted equality of opportunity and personal freedom instead of th e social equality desired by the Russians. The American constitution and Bill of Rights were created to protect personal liberties and individual freedom while the Russians were more concerned with the welfare and equality of the population as a whole. This difference is partially due to the differences in the conditions leading to revolution in each country. The American Revolution was initiated by the wealthy in response to what they considered unfair treatment by a foreign ruler while the Russian revolution was instigated by the poor in reaction to centuries of oppression and exploitation by the wealthy within their own country. In the years leading up to World War I, social unrest among the Russian people was spreading rapidly. There was a huge social gulf between the peasants who were former serfs and the landowners. The peasants regarded anyone who did not work as a parasite. They had always regarded as all land belonging to them. They regarded any land retained by the landowners at the time serfs were freed as stolen and only force could prevent them from taking it back. By the time Russia entered the war, one peasant rebellion had already been suppressed and several socialist revolutionary movements were developing.   Ã‚  Ã‚  Ã‚  Ã‚  In February of 1917 a group of female factory workers and led a revolt in which the Tsar was dethroned, only to be replaced by a provisionary government composed of the Russian elite. When this government did not live up to its promises of an end to Russian involvement in World War I, the Bolsheviks (â€Å"majority†), a revolutionary movement led by Vladimir Lenin, overthrew the provisionary government in what bacame known as the October revolution.

Virus and Bacteria

A virus is a capsule of protein that contains genetic material. A virus cannot reproduce on its own; it must infect a living cell to grow. Bacteria – Bacteria are one-celled organisms that live on their own. They can multiply and reproduce by subdivision Bacteria and viruses cause many of the diseases we are familiar with and may sound synonymous; they are greatly different from each other. [pic] o They differ greatly in size. The biggest viruses are only as large as the tiniest bacteria.Viruses are microscopic; they range in size from about 20 to 400 nanometers in diameter (1 nanometer = 10-9 meters). By contrast, the smallest bacteria are about 400 nanometres in size. o Another difference is their structure. Bacteria are complex compared to viruses. A typical bacterium has a rigid cell wall and a thin, rubbery cell membrane surrounding the fluid, or cytoplasm inside the cell. A bacterium contains all of the genetic information needed to make copies of itself—its DNAâ €”in a structure called a chromosome. In addition, it may have extra loose bits of DNA called plasmids floating in the cytoplasm.Bacteria also have ribosomes, tools necessary for copying DNA so bacteria can reproduce. Some have threadlike structures called flagella that they use to move. o A virus may or may not have an outermost spiky layer called the envelope. All viruses have a protein coat and a core of genetic material, either DNA or RNA. The main difference between viruses and bacteria is the way they reproduce. Bacteria, given the proper nutrients, can grow and reproduce on their own. But viruses cannot â€Å"live† or reproduce without getting inside some living cell, whether it's a plant, animal, or bacteria.Viral vs. Bacterial Reproduction Bacteria contain the genetic blueprint (DNA) and all the tools (ribosomes, proteins, etc. ) they need to reproduce themselves. Viruses are moochers. They contain only a limited genetic blueprint and they don't have the necessar y building tools. They have to invade other cells and hijack their cellular machinery to reproduce. Viruses invade by attaching to a cell and injecting their genes or by being swallowed up by the cell. Here's an example of viral infection. These are T4 bacteriophages. They are a kind of virus that infects bacteria.Here they are landing on the surface of an E. coli bacterium. The bacteriophage cuts a hole in the E. coli's cell wall. It then injects its genetic material into the bacterium. By taking over the E. coli's genetic machinery, the viral genes tell the bacterium to begin making new virus parts. These parts come together to make whole new viruses inside the bacterium. Eventually so many new viruses are made that the E. coli bursts open and dies, releasing all those new viruses to infect more cells! Some diseases caused by virus and bacteria:Name of the disease |Caused by |Name of the microbes | |Polio |Virus |polio | |Pneumonia |Virus / Bacteria |influenza virus (flu) | | | |r espiratory syncytial virus (RSV) | |Hepatitis |Virus |Hepatitis A Virus | | | |Hepatitis B Virus | |Mumps |Virus | | |Bronchitis |Virus |respiratory syncytial virus (RSV) | |AIDS |Virus |human immunodeficiency virus(HIV) | |Tuberculosis |Bacteria |Mycobacterium tuberculosis | |Tetanus |Bacteria |Clostridium tetani | |Anthrax |Bacteria | | |Diphtheria |Bacteria | | |Chicken Pox |Virus |varicella-zoster (VZV) |How bacteria and viruses enter the body To cause disease bacteria have to gain access to the body.The ways in which a bacteria can get access to an animal body are:†¢ Cuts†¢ Contaminated food or water†¢ Close contact with an infected person†¢ Contact with the faces of an infected person†¢ Breathing in the exhaled droplets when an infected person coughs or sneezes†¢ Indirectly, by touching contaminated surfaces – such as taps, toilet handles, toys and nappies.Viruses are spread from one person to another by:†¢ Coughs†¢ Sneezes†¢ Vomits†¢ Bites from infected animals or insects†¢ Exposure to infected bodily fluidsCuring a bacterial infection The body reacts to pathogenic bacteria by increasing local blood flow (inflammation) and sending in cells from the immune system to attack and destroy the bacteria.Antibodies produced by the immune system attach to the bacteria and help in their destruction. Serious infections can be treated with antibiotics, which work by disrupting the bacterium's metabolic processes. The body's response to viral infection Viruses pose a considerable challenge to the body's immune system because they hide inside cells. This makes it difficult for antibodies to reach them. However, special immune system cells, called T-lymphocytes, can recognize and kill cells containing viruses. Many viruses, when released from infected cells, will be effectively knocked out by antibodies, produced in response to infection or previous immunization.Antibiotics are useless against viral infecti ons. Antiviral drugs are available only for few viral diseases, such as influenza, herpes, hepatitis B and C and HIV, but research is ongoing. However, immunization is helpful in fighting viral infection. The large scale immunization has led to the eradication of small pox once one of the most feared viral disease. How to Know When You Need Antibiotics Don't expect antibiotics to cure every illness. Antibiotics are only effective against bacterial infections. In the past antibiotics were prescribed â€Å"just in case† the infection was bacterial rather than viral because it was thought that taking them â€Å"couldn't do any harm†. Wrong.This very practice has contributed to the development of antibiotic resistant strains of bacteria. While the use of antibiotics depends on the specific diagnosis, basic guidelines include: Colds and flu are caused by viruses. They can’t' be cured with antibiotics. Symptoms can last two weeks or more and should be allowed to run t heir course.Cough and bronchitis are almost always caused by viruses. However, if you have a lung condition or the illness lasts a long time; your infection may be caused by a bacteria instead. Your doctor may decide to try treatment with an antibiotic.Sore throats are most often caused by viruses. Strep throat is caused by bacteria and requires treatment with antibiotics. A throat swab and a lab test are needed before your doctor will prescribe an antibiotic for a sore throat.Ear infections often require the use of antibiotics. However, not all ear infections are bacterial infections.Sinus infections do not always indicate a bacterial infection.Even if you have a runny nose, or yellow or green mucus, you may not have a bacterial infection. Antibiotics should only be used for severe infections or infections that last more than two weeks. What is diarrhea? Diarrhea can be caused by a variety of bacteria, viruses, and parasites. Children can also have diarrhea without having an infect ion, such as when diarrhea is caused by food allergies or as a result of taking medications (such as antibiotics).A child is considered to have diarrhea when the child's bowel movements are both more frequent than usual and looser and more watery than usual. Children with diarrhea may have additional symptoms including nausea, vomiting, stomach aches, headache, or fever. Swine Flu: Swine flu is an infection caused by a virus. It's named for a virus that pigs can get. People do not normally get swine flu, but human infections can and do happen. The virus is contagious and can spread from human to human. Symptoms of swine flu in people are similar to the symptoms of regular human flu and include fever, sore throat, muscle pains, severe headache, coughing, chills, weakness and general discomfort.Figure: Electron microscope image of the reassorted H1N1 influenza virus photographed at the CDC Influenza Laboratory. The viruses are 80–120  nanometres in diameter. There are antivir al medicines you can take to prevent or treat swine flu. There is no vaccine available right now to protect against swine flu. You can help prevent the spread of germs that cause respiratory illnesses like influenza byCovering your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.Washing your hands often with soap and water, especially after you cough or sneeze. You can also use alcohol-based hand cleaners.Avoiding touching your eyes, nose or mouth. Germs spread this way. Trying to avoid close contact with sick people.Staying home from work or school if you are sick. Prevention of food to contaminate Here are four major tips recommended by the Centers for Disease Control and Prevention (CDCP) to prevent contaminating food.Use caution when buying food. o When at the grocery store, pick up perishable food such as meat, eggs, and milk at the very end of your shopping, so they will stay cool. o Take food home right away so that it doe s not spoil in a hot car. o Avoid raw or unpasteurized milk. o Because eggs, meat, seafood, and poultry are most likely to contain bacteria, do not allow their juices to drip on other food.Store food properly. Store eggs, raw meat, poultry, and seafood in the refrigerator. o A refrigerator should be set at 40 ° F. o A freezer should be set at 0 ° F. o Regularly clean and disinfect the refrigerator and freezer. o Use containers to prevent contaminating other foods or kitchen surfaces. Do not store food uncovered in the refrigerator or freezer.Use special precautions when preparing and cooking food. o Wash your hands and clean and disinfect kitchen surfaces before, during, and after handling, cooking, and serving food. o Defrost frozen food on a plate either in the refrigerator or in a microwave, but not on the counter. o Cook food immediately after defrosting.Use different dishes and utensils for raw foods than you use for cooked foods. o Wash raw fruits and vegetables before eat ing them.Cool and promptly store leftovers after food has been served. o Because harmful bacteria grow at room temperature, keep hot food hot at 140 ° F or higher, and keep cold food cold at 40 ° F or cooler. This is especially important during picnics and buffets. o Do not leave perishable foods out for more than two hours. o Promptly refrigerate or freeze leftovers in shallow containers or wrapped tightly in bags.Figure: (a) Components of virus, (b) components of bacteriaFigure: Reproduction of T4 bacteriophage Virus

Ancient Egyptian Art Ancient Egypt - 776 Words

Ancient Egyptian is one of the oldest countries in the world. It is divided into three kingdoms Old, Middle, and New. Today I will be discussing the beautiful Queen Nefertiti and her kingdom. She comes from the New Kingdom. Her name means the beautiful women has come and her husband who was Pharaoh Akhenaten ruled during the 14 century B.C. Artwork from the day depicts the couple in an unusually naturalistic and individualistic style, more so than from earlier eras. Ancient Egyptian Sculpture Queen Nefertiti ca. 1348-1336 B.C.E., Eighteenth Dynasty painted limestone, rock crystal eyes, height 20† (50.8cm) Staatliche Museum Zu Berlin.

Queen Nefertiti husband changed Egypt’s religious and political structure around the sun god named Aten. Akhenaten’s transformation of religion brought radical changes in artistic conventions. Departing from i dealized images of earlier pharaohs, Akhenaten is sometimes depicted with feminine hips and exaggerated features. Early images of Nefertiti show a stereotypical young woman, but in later ones she is a near mirror image of Akhenaten. Her final depictions reveal a regal but realistic figure. On the walls of the tombs and temples, she is depicted alongside her husband. That was rare in those times as no other Egyptian queen was idolized that way. She was shown in positions of power and authority and also driving a chariot or decapitating the enemy. Sumerian were the first people who migrate to Mesopotamia, they created a civilization 5,500 year ago. The Sumerians had a common language and believed in the same gods and goddesses called polytheism (History.com Staff, 2010). The Sumerian sculpture standing man is a statue that is made of black limestone with white gypsum. Compared to the Egyptian statue, they are easily recognized by their large eyes, single eyebrow, and seemingly as tonished facial expressions. The standing figure with clasped hands is a worshiper. It was placed in the â€Å"Square Temple† at Tell
