If you either put on a Band-Aid or stuck a Post-It note on your window you have encountered adhesives. Some inventions have given birth to other inventions, other inventions have found new uses. This is the case of the family of cyanoacrylates. In my house when something was broken my dad would reach for the Superglue or Gorilla Glue. In a matter of seconds the plate or cup was fixed good-as-new. Before the invention of these products I would have used Elmer’s glue and hoped after a long wait
Mouth Laceration A mouth laceration is a deep cut in the lining of your mouth (mucosa). The laceration may extend into your lip or go all the way through your mouth and cheek. Lacerations inside your mouth may involve your tongue, the insides of your cheeks, or the upper surface of your mouth (palate). Mouth lacerations may bleed a lot because your mouth has a very rich blood supply. Mouth lacerations may need to be repaired with stitches (sutures). CAUSES Any type of facial injury can cause
Today I arrived home from a longs day of work to find that my home has been burglarized. The officers were contacted by a neighbor that seen someone running from my home earlier today. Forensics was there collecting evidence and advised me to stay out of the home. The neighbor was not able to provide a description of the perpetrator. Officer Stone interviewed me and asked if I had any enemies or if I had seen anyone around that was not from the neighborhood. I have not noticed any suspicious
Present vs. Past: Forensic Science Forensic science is specialized in finding proof and evidence to analyze and search for clues. When crimes are done, criminals frequently leave behind evidence at the crime scene. Crime Investigators (AKA- CSIs) and Medical Examiners (MEs) the inspect the evidence left at the crime scene for leads to who did what. They try and rebuild the scene using the evidence and proof that they have. Forensic science has played a great role in finding evidence for crimes in
the process and outcome of each type of examination. Since the most common way the Denver Police Department analyzes prints in relation to firearms is cyanoacrylate ester fuming and fingerprint powders, in Maldonado’s study approximately 480 items were processed with orange magnetic powder the rest of the items were processed either cyanoacrylate ester fuming (super fuming) or RUVIS. The benefit of using RUVIS or super fuming is that they allow one to
cement or cyanoacrylate glue. Before gluing two pieces together, lay them out on a work board or wax paper and use pins to prevent the members from moving apart; the pins should not be placed near the joints so that it is easier while gluing (Anderson 2006). Then, apply the glue to the members and make sure that they touch to create the strongest joint possible. Despite it seeming as if more glue would make a structure stronger, using bulks of glue can cause the bridge to fail as cyanoacrylate bulk will
The history of fingerprint identification dates back all the way to the 200s BC. Ancient Chinese history shows details of using handprints as evidence in investigations of burglaries all the way back to 221-206 BC. Fingerprinting has been a major component in identification for crime scene investigations and law enforcement for centuries. History In July of 1858, the English began using fingerprints when Chief Magistrate of the Hooghly district in Jungipoor, India, James Herschel came up with the
being inserted. The focus of this research trial is to compare the two types of patient group’s, standard group who used transparent cloth- bordered polyurethane dressing to PIC and skin group who transparent cloth boarded polyurethane dressing + cyanoacrylate glue to hold PIC, comparison was investigated. Patients selected for groups comprised of patients admitted to the emergency department with preexisting inserted PIC, aged 18 years plus. Primary issue concentrated on PIC failure at 48 hours in
The Crash Imagine you are riding home from school on a friday in the spring. The sun is shining there is a nice breeze and you are cruising along on your 21 speed. Then, all of a sudden you fly over your handlebars and plummet towards the sidewalk. That's what happened to me back in the 8th grade. I probably would’ve been fine, but I wasn’t wearing a helmet. I hit the ground hard scraped my hands and knees. I looked up as my bike flipped over my head and the pedal hit me square in the forehead. I
I. Attention Getter: Did you know that fingerprints are one of the first things to form before we are born? II. Relevancy Statement: We all have them but probably have never really studied them. A. No two prints are alike. B. Once they form they don’t ever change unless the skin is damaged enough to cause a permanent scar. C. Scars can alter the ridge patterns of the fingerprint but once the scar has formed it will stay the same. III. Credibility Statement: In my research I learned that this persistence
Picture this. You are abducted by someone you do not know and the suspect takes you to a cabin in the middle of nowhere. He makes you do things. A detective located where you were taken after days of research. You are no longer there, so he requests an expert fingerprint specialist to come to the scene and lift the prints to try and find out your captives next move. The fingerprint specialist then asks himself where and what are we trying to find. It is then determined what substance they may use
only camel hair, ostrich feather, or a nylon brush can be used because those brushed don’t distort the print. Another way to take the print from the scene is a chemical path, most common chemicals including iodine, ninhydrin, silver nitrate, or cyanoacrylate esters. To apply these chemicals to the print one can either brush, spray, fume or dip the print in the substance. The last way to remove a fingerprint is using radiation (ultraviolet and laser). All of these methods are commonly used and will
Structural adhesives are used in a variety of applications such as automotive, durable goods, and building and construction. Adhesive chemistries can encompass one and two component polyurethane (PU), epoxy or cyanoacrylate, but in this article, we will discuss about the usage of polyurethane as the structural adhesive in automobile industry. Polyurethanes are made by the exothermic reactions between alcohols with two or more reactive hydroxyl (-OH) groups per molecule (diols, triols, polyols) and
In the competition known as Science Olympiad, there is an event build called “Boomilevers.” This event is comprised of building a structure to be attached on one side to a wall and bear the maximum weight possible on the other side, while the structure itself weighs as little as possible. The Boomilever is a long standing Olympiad Event and requires acute attention to detail and a critical mind in architecture in order to achieve the maximum efficiency score possible. There are many limitations and
The show CSI first appeared in the early 2000s and gained major popularity. Over time the show increased the expectations of viewers. The biggest expectations were the abilities of the crime scene investigators to always provide proof of evidence, as well as their methods used in gaining results from that evidence. Legal specialists anticipated the effects the show would have on the views of the legal system and how it would affect the juror process. This development is now referred to as the “CSI
