...Environmental and Global Health Issues Laralee Shaffmaster Western Governor’s University Environmental and Global Health Issues This paper on environmental and global health issues in community health nursing will discuss and analyze the communicable disease measles. It will present epidemiological data, causes, manifestations and the route of transmission for measles. A graphic representation of the measles outbreak will be presented to discuss the international pattern and movement of the disease. A discussion of how the measles outbreak could affect the community will also be presented. Next, this paper will present the appropriate protocol that a community health nurse will follow to report a SARS outbreak in the community. The last subject this paper will discuss is how a community health nurse modifies their care of clients with respiratory diseases during a time when the air quality index is poor. A. Measles Rubeola or measles is a respiratory disease. Measles is a virus that normally grows in the throat cells that line the back of the throat and lungs. Once infected, measles causes runny nose, fever, cough and a head to toe rash that occurs 14 days after exposure (CDC, 2013). A1. Outbreak In the year 2000 measles became eliminated in the United States. Elimination means the disease is no longer native to the U.S. and cases are not reported for a twelve month period in endemic proportions. Outbreaks occur when people travel to countries where the disease...

...Patel Laboratory #7 – Determination of Ka for Weak Acids Laboratory Date: April 25, 2012 Objective Titrate a solution of unknown acid to the half-reacted point and use the pH of the solution at that point to determine ka for the unknown acid. Titrate a solution containing a weighed amount of solid unknown acid to the half-reacted point and use the PH of the solution at that point to determine Ka for the unknown Ka for the unknown acid. Introduction When an uncharged weak acid is added to water, a heterogeneous equilibrium forms in which aqueous acid molecules, HA(aq), react with liquid water to form aqueous hydronium ions and aqueous anions, A-(aq). The latter are produced when the acid molecules lose H+ ions to water. HA(aq) + H2O(l) H3O+(aq) + A-(aq) Water is not included in the acid-dissociation equilibrium expression because the [H2O] has no effect on the equilibrium. Acid + Base→ Salt+ Water Materials Used 10, 50 and 100-mL graduated cylinder 125-mL flask 3.5-mL of 6M NaOH Solution Distilled Water Glass stirring rod Beaker 50-mL of Unknown Acid Solution 25- or 50-mL buret Ringstand with buret clamp 10-mL pipet 125mL flask Phenolphthalein indicator Short range pH paper pH meter Procedure A.

...! Lab Report: Scientific Method Your Name: ___________Jose Sebastian Flores Vera______________________ Purpose of this Lab What is the goal of this lab? What question is it trying to answer, or what problem is it trying to explain? This lab is for the application and understanding of the scientific method. The propose of this lab helps students to learn the metric system, its units, and the conversion from the English system to the metric system. Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Well, the addition of salt to tap water raises the boiling point of the water in a steady and constant way. Because the addition of the salt increases the number of atoms, then it will take a higher temperature to reach the boiling point. Experimental Design List the materials used in this lab, and the procedure you followed. Materials: 1. Tablespoon 2. Sharpie 3. Thermometer 4. Measuring cup 5. Kitchen stove 6. Several small pots 7. Table salt 8. Tap water Procedure (list steps in the order in which you performed them): 1. Pour 2 measured cups of tap water in the pot 2. Heat it up, record the boiling point with the thermometer. 3. Discard the water. 4. Pour 2 measured cups of tap water in the pot. 5. Add a tablespoon of salt. 6. Heat it up, record the boiling point with the...

Overview ABSTRACT The purpose of this study is to examine the effects of computer-based mathematics curriculum on problem solving and the students’ attitudes toward computer-based mathematics. Participants will be my 3rd grade students who will receive 2 hours weekly computer-guided math instruction along with their regular Math Investigations. The computer program that will be used in this study is Edutest. Edutest is a computer program that focuses on problem solving strategies, geometry, number sense, logic patterns, measurement, probability, and word problems that are in line with the district standards. The students will work independently on the computer with computer-guided instruction. During the study, students will take a pre test and posttest as well as on-going daily instruction in mathematics along with teacher made assessment tests in mathematics to measure their achievement levels. I will also take an attitude survey to gauge their feeling about using computer mathematics. A survey was given pre study and post study. This information was used to assist me in planning and implementing computer-based curriculum and to see whether their attitudes towards computer math will have an effect on how well they implement the program. I chose to study math because I enjoy...

...Unknown Laboratory Report Sarah Mansfield Biology 203 Professor Lana November 19, 2014 INTRODUCTION Microorganisms are the earliest forms of life and most have thrived since the early birth of the planet. They have evolved into many different forms of life such as animals, humans, and plants. While some microorganisms impact life in a positive way by sustaining life, others cause disease and even death (Nester, et al. 2012). Prokaryotes are one of the earliest organisms to exist, and many of these organisms can thrive in conditions far worse than other living things. For example, they can tolerate extreme temperatures, acidic, or alkaline environments (Foster 1996). Prokaryotic cells do...
