Adwoa Fosuah Bio Psych Lab Report 4 Cold Pressor Task Aim The cold pressor test is done by having the subject submerge their hands in a bucket of cold water to determine cardiovascular changes such as blood pressure and heart rate. For this experiment we wanted to know how long participant can keep their feet in the bucket of ice water before they experience any pain while looking at neutral and positive pictures and also rate the intensity of their pain. For this reason we hypothesized that

The purpose of this lab was to compare the action of a catalyst (enzyme) under different environmental conditions. This was determined by performing a variety of different experiments. The first experiment was performed by adding hydrogen peroxide to sand. Due to the fact that the sand was not soluble in the hydrogen peroxide‚ no reaction thus no catalyst were present. Manganese dioxide was also added to the hydrogen peroxide creating a moderately fast reaction thus leading to believe that an enzyme

SYSTEM ( Liebherr/Brastemp/Bosch/Electrolux) ONE COMPRESSOR + TWO IN-SERIES EVAPORATORS + ONE CONDENSER The compressor operates at the freezer evaporation temperature‚ and therefore the system overall efficient is also quite LOW. The FFC air and the FZC air circulate separately preventing the transfer of food odors‚ but the TEMPERATURE CONTROL of the compartments is rather COMPLEX.

Week 1 Lab Name_________ Part I - Directions: For the function we are going to estimate the area under the curve using the trapezoidal rule where n = 5 by doing the following: 1. Divide the interval into 5 equal pieces. How long is each piece? This will represent the width of the rectangles we will use to estimate the area in gray above. What will the x-values be for the endpoint of each piece? Width of rectangle = 0.4 .2 .8 1.6 2.4 3.2 2 2. Evaluate f(x) for x1 to x6

PREPARATION FOR: "MACPHERSON REFRIGERATION LIMITED" CASE Read the case‚ and answer the following questions: 1. Search in the library (books on Operations Management or Production Management)‚ to find the main components of the “Aggregate Production Planning” problem and briefly describe which are “pure strategies” and “mixed strategies” to solve this problem. The aggregate demand is the total demand for all products/services produced by a production facility without considering size‚ models

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

Sketch a velocity versus time and displacement versus time for a car approaching a red traffic light and then leaves it as the light turn green. 2. Jimmy took 8 hrs to drive his Civic from KL to Kota Bharu which was about 400 km away. What was the average speed of Jimmy in km/h? Why‚ in this case was the term average speed used over velocity? 3. A ball rolls with a velocity of 20 m/s on the ground and comes to a stop

Solve each of the following problems. Show your solution. 1. A hydraulic lift office chair has its seat attached to a piston with an area of 11.2 cm2. The chair is raised by exerting force on another piston‚ with an area of 4.12 cm2. If a person sitting on the chair exerts a downward force of 219 N‚ what force needs to be exerted on the small piston to lift the seat? Answer: a= 11.2 cm2 A= 4.12 cm2 f= 219 N F= 80.56 N F= fA / a ;

Write down an expression for the frequency of oscillation of one oxygen atom in terms of its mass m and the force constant K of one half of the spring. How is K related to the force constant k of the whole spring?[the force constant is the force per unit extension.] ii)From spectroscopic measurements of oxygen molecules ‚it may be deduced that the frequency of oscillation of the molecule is about 4.7 x10^13 Hz. In what region of the electromagnetic spectrum does radiation of this frequency lie? What
