CJ328: Forensic Fingerprint Analysis
Prof: Denise Womer
Based upon your expertise in regards to fingerprint and friction-skin development, explain why the following conclusion regarding human cloning is false. Premise: We all accept the proven fact that identical twins do not have the same fingerprints. However, human clones present a different set of friction skin development issues.
No! Studies have concluded that, even though the fingerprints of identical twins may be very similar, they are not identical. Twins have a very high correlation of loops, whorls and ridges. But the details (for example, where skin ridges meet, divide into branches, or end) differ

I don’t know how true or even possible this is, but I read an article a few years back on a woman cloning her daughter so that her daughter (who was sick) could have parts from the cloned child. Which I thought was crazy, because then they made a movie about it as well. So I really don’t even know if the article was true, or even if the movie is based off the article and if it’s true.

Explain the principles and processes used in the analysis, comparison, evaluation, and verification of latent fingerprints. Latent prints are formed when the body’s natural oils and sweat on the skin are deposited onto another surface. Latent prints can be found on a variety of surface they are not readily visible and detection often requires the use of fingerprint powders, chemical reagents or alternate light sources. Generally speaking, the smoother and less porous a surface is, the greater the potential that any latent prints present can be found and developed. Investigators often perform cyanoacrylate processing, or fuming, of a surface before applying powders or dye stains. This process, typically performed on non-porous surfaces, involves exposing the object to cyanoacrylate vapors. The vapors will adhere to any prints present on the object allowing them to be viewed with oblique ambient light or a white light source. (Latent, n.d)
Analysis involves assessing a print to determine if it can be used for a comparison. If the print is not
Identical twins look so similar because identical twins have the same genetic makeup, meaning, the same DNA (same nitrogenous bases). This is because by they are fertilized by the same egg, making them identical.

Introduction The purpose of this lab was to introduce chemical development as a way to develop latent fingerprints and to demonstrate two of these methods: cyanoacrylate fuming and iodine fuming. These two methods are regularly used to develop latent fingerprints. Cyanoacrylate (or superglue) fuming was discovered as a way to develop prints in the late 1970s. The fumes of heated cyanoacrylate react with the bodily fluids of a fingerprint.
Energy keeps all living organisms alive, as they need a continual supply of energy to function in order to survive. Some of these processes are continuous such as, metabolism, which is the chemical reactions which occur in the body, these occur by using or releasing energy from chemical substances. Another continuous process which use energy is the transporting of molecules in order for them to break down, and to build new ones. The breakdown of large molecules into their simpler forms to release energy is known as catabolism, for example, when glucose is used in a cell to release energy. And the opposite reaction, is called anabolism. This is when energy is used to build complex structures from simple cells, for example, tissue growth and

1.) Information Confidentiality: As an employee, you will be exposed to client-sensitive as well as company-sensitive information that is to be viewed only by those who have the authority or permission to do so. Such information to be considered “confidential” includes business contracts, financial information, internal correspondence, and any and all documentation (electronic or paper-based) that is not authorized to be disclosed to the public. Disclosure of sensitive information will lead to immediate termination and possible charges/fines (depending on the severity of the violation) as is legal under state and federal law.

1. ___L__ Bill perceived the cover of his book was red even though the light changed in the various rooms in which he read the book.
The company is in direct violation of the ADEA of 1967 which states (2)“certain applicant and employees who are 40 years of age and older are protected from discrimination on the basis of age in hiring, promotion, discharge, compensation, or terms, conditions or privileges of employment.” In this case the 68 year old employee could sue the company based on Age Discrimination and win.
A tenet of that theory is that enlightened egoists will recognize that socially responsible behavior will benefit them.
Traditionally, nutrition programs were targeted to the indigent and poor populations in developing countries. Many of today's Americans are malnourished also, but they are inundated with unhealthy foods and require a multidisciplinary approach to nutrition education. What would be the three most important points to include in a public nutrition program? Provide current literature to support your answer and include two nutritional education community resources.

FINGERPRINT EXPERIMENT2AbstractLatent print residue is a combination of many substances excreted from the body. Latent print residues may be left from natural sweat on the skin or from a contaminant such as motor oil, blood, ink, paint or some other form of dirt. They may exhibit only a small portion of the surface of a finger and may be smudged, distorted, overlapped by other prints from the same, or from different individuals, or all of these in combination. The factors that affect the quality or presenceof latent prints include the conditions involved between friction skin contact and the objects that are touched. Pre-transfer conditions describe the condition of the friction skin and the amount and type of residue on the skin; and are affected
“Fingerprint recognition is one of the divorce inference using the impressions made by the minute ridge formations or patterns found on the fingertips. No two people have exactly the same arrangement of the ridge patterns, and the remaining patterns of any one individual unchanged. Fingerprints infallible provide a means of personal identification. Other personal characteristics may change, but not fingerprints”. (1)
There will be 8 different finger-marks that will be used each time for each experiment that will take place. These prints will be created by one individual to be able to keep a constant pattern within the practical. There are two slightly methods that will be used, the first method is cyanoacrylate fuming the item that contains the print will be suspended within the tank this is to ensure that the item is exposed to the fumes. This process will take up to 45 minutes once the time is completed the whitish coloured print will appear on the item showing the finger-mark/s. The print can be enhance further using a fluorescent dye the fan is then turned on and is then used to circulate the fumes which will then increase the surface contact between the latent print residue and the cyanoacrylate vapours. A heating method will then be applied and the cyanoacrylate will be placed onto a dish and then a heating tool will then be placed onto the dish until it accelerates the polymerization process of the cyanoacrylate however there is a possibility that heating the cyanoacrylate will accelerate the volatility which then in turn will mean a faster vapour release which will then accelerate the recovery of the latent print. Another method that is going to be used within this practical is like the first method, however this current method will be using approximately 25 drops of liquid cyanoacrylate and this will then be placed into a magnetically locked in a shelf above the item that is about to be fumed. The fume cupboard will then be heated to 120 degrees with the humidity being maintained at 80 degrees. The heating and the humidity cycle will then take approximately 30 minutes, the fuming cabinet will need to take 20 minutes to remove any harmful residual vapours. Once this is complete the print that has been exposed by the fumes
