A lot of people don’t get tested because they don’t believe something like this can happen to them until it do then they walk around miserable and feel as if life is over. Getting tested every six months makes a difference depending on how sexually active you are you might want to get tested more. I personally get tested every 3 months because my mother died from this virus and I do not want to leave my kids the same way she left me. Although you may not be that comfortable it is for the better

Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by

Expt. 8.1 Thin Layer Chromatography (TLC) Analysis of Analgesics Krista Jinks CH 211L Section F 10/27/14 I. Abstract: The objective of this experiment was to analyze analgesic tablets by TLC to determine what analgesics they contain. The analgesics that could be in the tablets included ibuprofen‚ acetaminophen‚ aspirin‚ and caffeine. Through the use of TLC‚ unknown substance #62 was found to be Bayer Aspirin because it only contained aspirin. II. Introduction: 1. Briefly describe

Determination of Cleansing Action of Detergents (Using Capillary rise) Synopsis This project report explains about the surface tension and capillarity of liquid through a simple experiment of finding the capillarity of various detergents. Oil stains and grease on dirty clothes cannot be removed‚ using water alone‚ because water does not wet them. If detergents added ‚ surface tension is decreased‚ the area of contact is increased

Do all liquids evaporate? What would happen if liquids never evaporated? Do we know which liquid evaporates the fastest? Could we perhaps use this knowledge to change the everyday processes? The process of evaporation happens much differently than scientists once thought. Every liquid eventually evaporates and often what remains is the solid particles which were once part of the solution. Evaporation is very important: “it shapes the climate of the planet‚ it affects the cost of car travel

What is first aid? First aid is the provision of initial care for an illness or injury. It is usually performed by non-expert‚ but trained personnel to a sick or injured person until definitive medical treatment can be accessed. Certain self-limiting illnesses or minor injuries may not require further medical care past the first aid intervention. It generally consists of a series of simple and in some cases‚ potentially life-saving techniques that an individual can be trained to perform with minimal

Section 1 As a member of Group 2‚ we were investigating why the liquids Ethanol‚ Propanol‚ Water‚ Pentane and Acetone evaporate at different rates. Methanol and Butanol were not liquids investigated by our group‚ but collectively as a class we were able to record averages of rates of evaporation.

FE 106 GENERAL CHEMISTRY EXPERIMENT-1 DENSITY OF LIQUIDS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will learn how can we find the density of liquids and liquids of density how change effect of temperature‚ pressure‚ mass‚ volume and concentration. For this reason we will take NaCI solutions with different concentrations and we will measure their densities‚ so we will find out the effects of concentration on density of solutions. THEORY:
