The Crime Lab Project is a non-profit corporation with a blog created for “raising awareness of public forensic science needs and challenges”(What is the Crime Lab Project 1). By reinforcing forensic science education and research‚ forensic science can contribute to a more just society‚ and in turn better everyone’s lives. ¨A recent congressionally mandated report by the National Academy of Sciences found¨ that there are serious deficiencies in the nation’s forensic science system and are in much

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

with this optional observation lab was a great experience overall‚ just as I had expected it to be. I was much more interested in participating in the observations versus sitting in a classroom every week and attending the labs like in 1010. The first event that I attended was the courtyard telescope setup on January 31st‚ in which we were observing a couple of different provinces and sunspots located about 10 o’clock region located directly on the sun. (See lab book for illustration.) We were

colorless colonies. Multiple medical experiments are credited towards transformation‚ especially ones involving cancer and the transformation of normal cells to neoplastic and cancerous cells. Introduction The general purpose of the Transformation Lab was to observe the difference in bacterial growth under differing media conditions to help understand the process of transformation and how it contributes to the life of living organisms. "Transformation" is what occurs when a cell receives and expresses

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

In 1978‚ The Airline Deregulation Act was purposed and signed by President Jimmy Carter. This federal law came into existence for two main reasons; stated by Carter (1978)‚ “to help our fight against inflation‚ and to ensure American citizens of an opportunity for low-priced air transportation. Today’s motives in the airline industry go way beyond economic decisions for themselves as well as their shareholders. Nowadays‚ businesses are an essential part of society and the airline industry must

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Short-Term Scheduling GLOBAL COMPANY PROFILE: Scheduling Airplanes When Weather Is the Enemy Throughout the ordeals of tornadoes‚ ice storms‚ and snowstorms‚ airlines across the globe struggle to cope with delays‚ cancellation‚ and furious passengers. Close to 10% of Delta Airline’s flights are disrupted in a typical year‚ half because of weather; the cost is the $440 million in lost revenue‚ overtime pay‚ and food and lodging vouchers. Now Delta is taking the sting out of the scheduling nightmares
