Fibers

Fibers are everywhere in everyone. Fibers are threadlike elements from fabric or other materials such as carpet. They are mostly identifiable under a microscope, Fabrics are helpful in forensics in many ways. Fabrics are made fiber strands that are much longer than they are wide and generally round on cross section. These fibers may be from natural or synthetic sources.The main reason why fabrics are helpful is because fibers are in clothing,upholstery, carpet, rope, and building components.…

compared to the pricey and slow internet speeds of the U.S at 15 MBPS for $5.66 per MBPS. That is almost six times slower and 14 times more expensive than Japan. There are many possible solutions ranging from expensive options such as Google Fiber, Sony ‘Nuro’, Fiber-to-the-home (FTTH), and inexpensive options like local service providers contributing to the increase in internet bandwidth. Many people grew up with either dial up connection or satellite connection. Having said this,…

Trace Evidence: Hair & Fibers Analysis Trace Evidence Defined as materials that could be transferred during the commission of a violent crime, trace evidence consists of multiple sources of which include hair, fibers, soil, gunshot residue, among many more. Trace evidence can be transferred between people, objects, or the environment during the commission of a crime (Federal Bureau of Investigation, 2016). This idea is known as the Locard exchange principle which is the idea that whenever…

necessary, and it might be discovered through experience, but nonetheless, it’s necessary. This would mean that pain=c fibers firing is a posterori and necessary. In modal logic, necessary truth means that it is always true no matter what, even in every possible world (this will be discussed later). But the problem with this is that it is presumed that Kripke believes that pain=c fibers firing is an identity, and therefore is necessary, because both terms are rigid designators. Rigid designation…

It's not where you start, it's where you finish. So get the morning off to a great start with a bowl of high fiber cereal with fresh fruit. Fiberlady is pleased to inform you that if you choose a cereal high in fiber with your favorite fruit topping, you could get as much as a third of your daily fiber requirement. For optimal health, 25-30 daily grams of fiber-rich foods is the goal. High fiber foods effectively reduce the risk of cancer, gastrointestinal conditions and diseases, and the all…

muscle fiber types. All muscle fibers are having varying amounts of mitochondria in them. Mitochondria helps the muscle be able to manufacture ATP for contraction. To differentiate between the three muscles is based on their make up. Slow oxidative (SO) or type one muscle fibers are composed with the most mitochondria to help them be fatigue resistant. SO muscle fibers stain the darkest because the enzyme targeted by the stain is most abundant in this muscle fiber type. These muscle fiber types…

Short Questions 1.1 Fibers can be divided into 2 main categories: Manufactured fibers (Synthetic fibers and Regenerated fibers) and Natural fibers, but a fiber has still the same composition in both: A fiber is a material that is hair-like, longer than it is wide and fibers can be identified by their flexibility and being able to be spun into yarn or made into fabrics. 1.2 Staple fibers can be defined as natural fibers that can be twisted to form properties of yarn. Staple fibers are popular…

Wright How the hair of fiber made a connection for the case (what the analysis told them): There was hair clenched in Anagnos’ hand and the investigators thought it was Wright’s hair, but due to lack of technology, they couldn’t determine if it was his or not. 33 years later they retested the hair follicles and it proved Wright guilty. Name of the Case: Elizabeth Ballard Case Victim: Elizabeth Ballard Suspects: Chris Faviell and Charles “Eva” Martinez How the hair of fiber made a connection…

conducted a series of tests and analyses: a burn test, a microscopic fiber analysis, and a microscopic hair analysis. These tests and analyses all pointed to Mr. Marquez. Under the microscope, the fiber found on the crime scene looks exactly the same as a wool sample. They are both off-white with little strands wrapping around to create a bigger fiber. Additionally, we compared the two fibers in a burn test. In this test, both fibers produced a similar scent as they burned; they both smelled…

bamboo was harvested and processed using several methods to obtain the fiber. In alkali extraction method, the bamboo was cut into thin slabs with length and thickness of 25 cm and 3 mm, respectively. The slabs were immersed in different concentration NaOH solution (1%, 2%, 3%) at 70 ⁰C for 10 h. This study showed that only 1% NaOH resulted in higher mechanical properties. The roller looser was then used to produce small fibers. Then, they were washed and dried in an oven for 24 h at 105 ⁰C. For…
