- HONORS PROGRAM Acid-Base Properties of Natural Adsorbents of Synthetic Dyes Rada-Mayya Kostadinova 1. INTRODUCTION Dyes are synthetic, water-soluble and dispersible organic compounds, which cause coloration of natural water bodies when released into the environment. They are widely used in industries such as dyestuff, textiles, rubber, leather, paper, plastics, cosmetics etc., to color their products and are invariably left in the industrial wastes. Synthetic dyes, suspended solids and dissolved organics are the main hazardous materials found in textile effluents.... [tags: Scientific Experiment]

- Life cannot exist without water. The basis of everything living is water. About sixty percent of an adult human is made up of water and each day that person should intake at least six to eight glasses of water a day. If there was no water there would be nothing to drink to keep a body hydrated because every known liquid is made up of or contains water. A person can only survive three days without water. Only two and a half percent of the water on the earth is drinkable, which is a small percentage considering the amount of water on the earth and the size of the world and population....

- "Contaminants in Drinking Water" Ground water is always under threat and attack because of the escalation of cultivation, urbanization and industrialization. Over one third of Canadians use ground water as drinking water. Ground water is water that is located and stored under ground's surface. It is used in many different ways; for example, agriculture, drinking and industrial processes. Water contamination is any changes to water's biological, physical or chemical properties that will make the water harmful, and unfit for drinking or using....

- It is important to study bacterial transformation, because bacteria is an organism with the unique ability to take up foreign DNA particles. Bacterial transformation gives bacteria an evolutionary advantage, such as antibiotic resistance. The purpose of this lab was to determine if E.coli could be transformed by introducing it with a plasmid into its DNA. In this experiment, E.coli was treated to be competent by calcium chloride in the process of chemical competency. DNA was then able to enter the cell through a plasmid that is resistant to ampicillin, causing E.coli to be transformed.... [tags: DNA, Bacteria, Molecular biology]

- What is Bacterial Infection of the Uterus in Cats. Metritis is a bacterial infection of the uterus that normally occurs within a week after the cat gives birth. Symptoms occur when the lining of the uterus, or endometrium, becomes inflamed. Though it most often occurs after a natural birth, the condition can also be caused by a miscarriage, a natural or medical abortion or artificial insemination. The condition differs from pyometra, an infection of the uterus caused by hormones, as it is typically caused by bacteria such as Escherichia coli.... [tags: Immune system, Bacteria, Blood, Uterus]

- Antibiotics are widely used across the population to treat bacterial infections. The ability for these antibiotics to induce bacterial cells is fixed on the cellular function inhibited by a specific drug-target interaction (1). Antibiotics are classified in many ways. One way to classify types of antibiotics is whether they have the ability to induce the cell death – bactericidal drugs – or inhibit cell growth – bacteriostatic drugs (1). Another method of classifying antibiotic is the mechanisms of action they undergo.... [tags: DNA, Bacteria, Gene, Antibiotic resistance]

- Leptospirosis Leptospirosis is disease that is seen worldwide in both humans and animals. Leptospirosis can affect most mammals and has a multitude of clinical signs or symptoms and has varying degrees of infectivity. It can be tricky to diagnose, can be fatal, and has the potential of infecting humans. Leptospirosis is a disease that is becoming increasingly prominent in the world and has even been causing epidemics in countries because it is frequently misunderstood. For these reasons alone it is vital to know how to help diagnose, treat, and prevent this disease in our veterinary patients.... [tags: Infection, Infectious disease, Bacteria]

- An ever increasing problem in our society is the introduction of contaminants into our water supply. Water infiltration and the transportation of contaminants from anthropogenic activities into aquifers present a health risk to human populations. This problem is more extreme in areas of poverty wherein proper restrictions are not in place, but is still present in developed nations such as the United States and Canada. Because of agricultural byproducts, landfills, and industrial waste polluting groundwater in fractured rock (Levison, J.K., and Novakowski, K.S) and the vulnerability of aquifer to contaminant transport (Masciopinto, C., Caputo, M.C., De Carlo, L., and Nimmo, J.R.), populations...

- The objective of this study was to record a quantitative approximation of how many bacteria are present within various samples of meat products. The bacterial content of each meat sample is vital information in regards to improvements within the meat processing industry, and gives reason for changing or sustaining current feeding and processing conditions. Understanding which methods taken in processing meat that is sold to the public is a matter of public health, as obtaining and maintaining lower levels of bacteria in meats will reduce the likelihood of succumbing to illness from the consumption of such products by the end consumer....

- There are three different types of meningitis; viral, fungal, and bacterial meningitis. Although not as common as viral meningitis, bacterial meningitis is more likely to leave individuals with permanent disabilities. In children, disabilities can range from deafness, hearing loss, and cerebral palsy. the most common after effects. And in adults, septic shock, brain swelling, and hydrocephalus are most likely to occur if the disease advances without treatment within a sufficient time period. The three main bacteria responsible for bacterial meningitis are streptococcus pneumoniae, haemophilus influenza type B (Hib), and neisseria meningitidis.... [tags: Medicine Bacteria]
