Lab Report: DRILLING FLUID (MUD) DENSITY Objective: The aim of this experiment is to determine the mud density‚ specific gravity and hydrostatic pressure gradient for water-based-mud‚ WBM (Drilling fluid) using the OFITE mud balance. Theory: Drilling fluids are used during the drilling of boreholes‚ either for oil wells or water boles holes. One of the major functions of a drilling fluid includes providing hydrostatic pressure to prevent formation fluids from entering the wellbore. To ensure

Genetically Modified Organisms INTRODUCTION: The purpose of this lab was to identify if non-labeled food products are actually genetically modified foods. Before we could begin testing this theory we first had to gain an understanding about genetically modified organisms in general. This was rather easy because if you have been to any grocery store lately you have without a doubt seen products with labels saying "GMO-free" or even "contains only non-GMO ingredients." GMO actually stands for

Introduction There are two groups of reflexes in the human body‚ with two ways to categorize each of them. Reflexes can either be inborn and connected through the nervous system‚ or they can be learned through practice. Another way to explain a reflexive category would be autonomic reflexes or somatic reflexes. Autonomic reflexes are those which are unaware to us and act on visceral organs of the body‚ whereas somatic reflexes involve skeletal muscle stimulation. Both types of reflexes are put into

Separating Substances: Identifying Food Dyes with TLC Background The color of food is an integral part of our culture and enjoyment of life. Who would deny the mouth-watering appeal of a deep-pink strawberry ice cream on a hot summer’s day or a golden Thanksgiving turkey garnished with fresh green parsley? Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow color

It was hypothesized that if the animal was larger‚ then it would have larger hemoglobin. It was thought that larger mammals would need more oxygen-rich hemoglobin to support healthy function. This lab did not support this hypothesis. The results in table 1 displayed that the hemoglobin of all mammalian samples traveled about the same distance. This trend can be seen in graph 1 as the mammalian hemoglobin samples migrated the same distance. Because the proteins traveled around the same distance it

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

The purpose of this lab was to determine how different conditions could affect one’s heart rate. In the life of a human‚ the heart beats approximately forty-five million times per year varying based off of factors like age‚ gender‚ physical activity level (1). Furthermore‚ throughout the course of a day‚ the heart can vary in its heart rate from a number of different environmental changes such as prolonged standing‚ altered breathing (inhale vs. exhale)‚ and jolts of excitement such as being startled

INTRODUCTION As for the visual documentation of a living or dead specimen‚ digital photography has largely replaced traditional illustrations of the living specimen as the standard method of recording the colour and anatomy of the specimen in the field today. Earlier traditional illustration (coloured and black and white) are still considered scientifically important because they can stress fine anatomical features that are often obscured by liquid. Even today‚ these earlier traditional illustrations

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized
