...Chromatography which literally means “color writing” was invented by Mikhail Tsvet, a Russian botanist in 1903 while studying the coloring materials in plant life. It is defined as a laboratory technique utilized by scientists for the separation of organic and inorganic mixtures into their respective components in order to analyze, identify, purify and/or quantify the mixture or components. There are different types of chromatography which are use including liquid chromatography, gas chromatography, ion-exchange chromatography, paper chromatography and thin-layer chromatography. In consonance with these, while each type of chromatography uses different methods to separate compounds, all forms work on the same principle. They all have a stationary...

...Diagnosis of an Infected Patient: Microbiology Paper Bio 212 18 January 2015 Diagnosis of an Infected Patient After collecting a sputum sample from a patient that is suspected or may be infected with a bacterium from one of the following genera: Escherichia, Mycoplasma or Bacillus; Each bacteria listed should be isolated by utilizing each of the various staining techniques. The best staining techniques to use is the Gram stain or the Acid- fast stain due to the fact that they both will provide a lot of information in detail regarding the bacteria being studied. It is very important to be observant of how each bacterium obtained reacts to each stain, and how the results obtained will lead us in a developing diagnosis. The first technique being used is the Gram stain. Gram stain is probably one of the most common used staining procedures used in the field of microbiology. It is one of the differential stains that are used to characterize bacteria in one of the two groups: either gram positive or gram negative bacteria. Bacteria prepared for the Gram stain is a heated fixed smear that is covered with a crystal violet. Because the purple stain impart its color to all cells. After a short period of time, the purple dye is then washed off, and the smear is then covered with iodine, a mordant. When the iodine is then washed off, both the gram-positive and gram-negative bacteria appear dark violet in color or purple. The next, process is the slide is then washed with alcohol...

...Research and Background The Nacirema tribe and their strange behaviors were first documented by Horace Miner in “The Body Ritual Among the Nacirema” in 1956. Considerable effort has been extended to the study of this most unusual tribe in the years that followed and many print articles and lectures were devoted to trying to understand these people and their strange customs. Recently, many new research techniques combined with a host of motivated anthropologists and a fresh source of both corporate donations and governmental funds have uncovered new information about the Nacirema. Although there are hundreds or perhaps thousands of Nacirema rituals, ceremonies, and practices that merit intense study and analysis, the focus of this research paper is perhaps one of the most bizarre and poorly understood of all their rituals. This ritual has it’s roots in many different cultures dispersed across the world dating back hundreds of years. This most interesting ritual has been celebrated in a very concentrated region of Nacirema for hundreds of years located in a few costal cities north of the body of water “Gulf of the Land of Maize”. Although this ritual is celebrated to some degree in selected Nacirema cities of this region, the epicenter of this ritual and it’s many strange customs is the city that straddles the end of the big river Ojibwe. This city is “Crescent City”, aptly named for the villages of the city that followed the curvature of the big river Ojibwe. Once per...

...STATEMENT OF PROBLEM The Nursing Evidence Based Practice and Research Committee of Los Robles and Medical Center in collaboration with the Patient Safety Committee requested a trial of the Clasp Alert ID band to evaluate feasibility of adoption. Evaluation of ease of application, ease of identification of patient status, patient comfort, and pressure or skin irritability. RESEARCH Safety has been a major concern in the healthcare setting across the country. With the advent of the 20008 National Patient Safety goals, a national initiative to standardize Color-coded wristbands is underway. With the growing utilization of traveling nurses across the country, in December 2006 the Colorado Foundation for Medical Care, the Colorado Health and Hospital Association and the Colorado Nurses Association in collaboration with the Western Region Alliance for Patient Safety conducted a multi-state regional initiative to standardize patient wristbands in hospitals. The workgroups from this multi-state region selected standard colors with the following recommendations that hospitals adopt: DNR- Do Not Resuscitate as the color PURPLE, Fall Risk Alert designation as YELLOW, Allergy Alert designation as RED. The CFMC and the multi-state regional workgroups are just one example of the national initiative to standardize color-coded wristbands to increase patient safety (Colorado Nurse, page 17, 2006). The result was regional standardized color-coded wristbands. In November of 2006, The Missouri...

The first experiment we did was testing the unknown to see if it was a gram-negative bacterium or whether it was a gram-positive bacterium. Majority of the bacteria that had been handled with in class fell under gram negative. How to tell whether the bacteria is gram negative or gram positive is by staining the bacteria and watching it change it’s color. If the bacteria turn purple, that would show that the bacteria are gram-positive. If the bacteria turn red, then that would...

...I would never peer review or revise my own papers. With the amount of revisions that were undertaken in all four projects, I feel that I have become more comfortable in the act of revision. Also, I was never good at incorporating forms of evidence to support my claims, ideas and arguments. This class was very helpful in showing how to take research and incorporate it into a project. Overall, this class has allowed me to strengthen my skills as a reviser, helped me “formulate and articulate a stance through my writing”, and helped me to use more forms of evidence to support my claims, ideas and arguments. Project 1 was the simplest of the four projects. I decided to analyze a research article on Marketing and how companies have started to move their businesses into developing nations. At first I didn’t think I would be able to write a rhetorical analysis on this article because of its length but after multiple revisions and help from peers I wrote my final draft. This was the one project where the revisions really helped me grow as a writer. Without these revisions I would have written a terrible analysis because I had no idea how to explain the ideas in the article because it was so short. My peers gave me guidance and used their papers to help formulate my own paper. Prior to this assignment I had written papers detailing articles read but I had never done so with such a short piece. It was hard to fit enough words into the paper without sounding...

The navigation has to be precise while the screen design has to come alive with the simple icons and background activity. The background will have a gradient of the blue color, which will be enhanced to create a glossy/ glass look and will have some little faded birds and butterflies animation to bring the project to life. The main colors that will be used in this project will be Blue (sky), Black and white. These colors will bring the project a crisp clear look. Other minor colors include Red, Green, and Purple. These colors will mostly be used to either show the difference between icons/buttons in the screen design or interface. The content of the project have to be brought to life and also have to be one way or another related to the topic/purpose of the project. Some of the contents that might be used will include, leaves, birds, butterflies, trees, water etc. In the project proposal, it was an idea put on paper but this next step will ensure that the idea is represented visually and the message is straight forth and clear. The whole idea of putting the idea on paper into a computer based visual display is to make it really catchy, easy, fun and very interactive to the user or the intended audience.

Chapter I Introduction A. Background of the Study With a unique combination of crunchy texture and sweet, tart flavor, grapes have gained extreme popularity throughout the world. Grape is the second most popular fruit after oranges. It can be eaten as a refreshing snack as well as used in vegetable and fruit salads. It can be consumed in fresh or preserved form. It can be canned in jellies, crushed to prepare juices or wines and dried to prepare raisins. Grapes were introduced to America by the Spanish explorers approximately 300 years ago. There are more than 60 species and 8000 varieties of grapes all over the world. Some common varieties of grapes are blue, black, green, red, golden, blue-black, white and purple. Grapes consist of about 80% of water, which make them a low-calorie snack or dessert. Raisins or dried grapes consist...

...Examining Mendel’s “First Law”: Observing Anthocyanin in Brassica rapa Abstract The foundation of genetics lies with the principles that Gregor Mendel outlined after his experiments with pea plants where he discovered the relationship between physical characteristics, or phenotype, and genetic traits, or genotype. This experiment aimed to reproduce Mendel’s results with the Brassica rapa plant, noted for it’s fast generation time, and anthocyanin, a purple pigment that can be visually tracked through subsequent generations. It is important for experiments resulting in scientific discovery to be replicable and peer reviewed. Since Mendelian genetics are the foundation of scientific education, including answering questions about evolution and heredity of beneficial or fatal genes, his experiment is a valid and important choice. The hypothesis was that the presence of anthocyanin in Brassica rapa follows Mendel’s laws. By germinating the P1 generation and creating the F1 and F2 generations through pollination the hypothesis was tested. The experimental hypothesis was accepted with ------ error and the null hypothesis that these results were due to chance was rejected. Introduction A phenotype provides a clear visual cue for examining the inheritance pattern of genotypes and whether or not these patterns follow Mendelian genetic principles. Gregor Mendel is someone who is often referred to as the “father of genetics,” and discovered important theory pertaining to heredity...

...the results of all tests were compared as a class to try and determine which groups had the same unknown solids based on similarities in properties. It was found that my given unknown solid #11 shared similar properties with the unknown solid #1. A side by side analysis of the reactivity test in which Hydrochloric acid (HCI), lead nitrate (Pb(NO3)2) and sodium hydroxide (NaOH) was added to three separate samples of the compounds unknown #1 and #11 aqueous solutions. The results for both unknowns were identical, leading to the conclusion that my unknown solid #11 was the same unknown solid as #1. Introduction When conducting research it is important to be comfortable communicating your results with other researchers so that they can be further analyzed and compared with the results of other research experiments. Another large part of conducting research is to be comfortable determining, describing and comparing chemical and physical properties of compounds. Many compounds can look very similar, but have drastically different chemical properties, so it is important to know which tests can be performed on a compound to help determine what it is, or what it is not. In this experiment 2 sets of six unknown solid compounds were put into small jars and labeled with the numbers 1-12, numbers 4, 6 and 8 were not used. Each lab group was given one unknown solid and told to determine the samples properties through various testing. Physical characteristics were observed, by using a magnifying...
