group which was treated with reference drug (Diazepam 2 mg/kg bw). The third and fourth groups were considered as test groups and were treated with SMCE at the dose level of 100mg and 200mg/kg bw respectively. Animals were fasted 18 h prior to the experiment. An adaptation period of about forty five minutes after the drug treatment‚ the experimental animals were placed individually in the center of a platform facing one of the arms was closed‚ because animals naturally prefer the enclosed arms‚ as the

Rachel Bohnenberger Professor Van Doorn ENVS 150-002 27 April 2015 GMOs Lab Report Introduction As the population of Earth increases exponentially‚ so does the demand for more food. One of the solutions to the question of how more food can be produced is Genetically Modified Organisms‚ or GMOs. There is an ongoing debate about whether or not GMOs are more beneficial or harmful to society. Some of the benefits to GMOs are: growing plants‚ such as corn‚ that are resistant to weeds and pests‚ larger

Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

ABSTRACT On the past two weeks‚ I have done an experiment on hydrostatics‚ or is also known as fluid statics (fluid at rest) within the fluid mechanics field of study. This condition explains that in a stable condition‚ the fluid is at rest. The use of fluid in doing work is known as hydraulics‚ and the science of fluid in motion is known as fluid dynamics. INTRODUCTION The natural nature of fluids are they cannot remain stationary under the application of shear stress. However‚ fluid

Laboratory Experiment 1 EML 3303C Mechanical Engineering Measurements Summer 2014 Authored by: Cody Appleby‚ Gregory Harmeling‚ and Joseph Pernici May 26th‚ 2014 Lab section: C014 Monday 11am-1:50pm TA: Eduardo Castillo Work station 8 1 Abstract This lab consisted of three different measurements; measuring length‚ flow rate‚ and resistance. The reason for this lab was to use statistical concepts learned in lecture to analyze data and to become more familiar with the lab equipment

AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =

Experiment 2: Synthesis of Isoamyl Acetate (Banana Flavor) Paul Symon C. Manuel*‚ Katherine Merene‚ Charlene Mondelo‚ and Pamela Mallari Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract: The purpose of this experiment was to synthesize isoamyl acetate via an esterification reaction between acetic acid and isoamyl alcohol‚ using concentrated sulfuric acid as a catalyst. The product was washed with sodium hydrogen carbonate‚ as well as with water‚ and then dried

There are many different types of cigarettes in the world and although no matter which type is smoked there will be a high carcinogen uptake as well as other chemical resulting in a higher chance of developing cancer and lower cilia beat rates. This experiment took two cigarettes; one with a paper filter‚ and the other with charcoal filter. By taking mollusk gills and placing them in contaminated water from the two different smokes it could be seen that the cilia on the gills had a slower beat rate then

Behavior of Gases and Absolute Zero Determination Lab Report Experiment 4 Introduction In this experiment we measured the relationship between temperature‚ volume‚ and pressure. Objectives: Conduct a set of experiments‚ each of which illustrates a gas law. Gather data to identify the gas law described by each activity. Complete the calculations necessary to evaluate the gas law in each activity. From your results‚ derive a single mathematical relationship that relates pressure‚ volume‚ and
