collagen fibers and depending on the direction these fibers are running the matrix can be categorized as dense regular or dense irregular. In dense regular collagenous connective tissue the collagen fibers run in the same parallel direction. Which helps tendons to attach muscle to the bone and ligaments to attach bones to other bones.…

hair and fibers were used to convict Wayne Williams. A single hair can contain multiple things that can point a individual to a crime. Hair has certain characteristics that can pinpoint to whom the hair belongs to. Hair of a human will be much thinner compared to animal hair. Hair that is curly or darkly pigmented can be of a African American being. Fibers are of those left behind of a clothing or carpet of some sort. Fibers can determine where an individual has been based upon the fibers on…

It is seen that the tensile strength of the jute/epoxy composite increases with increase in fiber volume fraction up to 10 vol.…

Kevlar Kevlar (poly para-phenylene terephthalamide) is a registered trademark for para-aromatic polyamide synthetic fiber that contains polymer (multiple chain bonds) which makes it extremely strong. It is flexible, light, and thermal stability allowing this unique synthetic fiber to be used in advanced technology applications such as bulletproof materials. Invention The invention of Kevlar® was developed in 1965 by a chemist, Stephanie Kwolek. Kwolek made the breakthrough while working at…

maximal contractions occurring in short bouts. It also focuses on muscle hypertrophy, or the enlargement of muscle fibers (Knuiman, 2015). Due to this fact, skeletal muscle adapts to each type of exercise very differently. To understand how skeletal muscle fibers…

The FDA, provides an online website that provides information on numerous topics, like for example artificial sweeteners. With the help of the FDA, there is information provided to us the public. Through this website we know what artificial sweeteners are and if they are safe. There is a…

Fiber Cases Name of the Case: Tiny Fibers Helped FBI Nab Serial Killer Victim: Sofia Silva, Kati Lisk, Kristin Lisk. Suspects: Richard Marc Evonitz. How the Hair of Fiber Made a Connection for the Case: There was a correlation in evidence all that was left were tiny pieces of fiber that’s it. It first started with the death of Sofia Silva, a tiny piece of pink fiber was found on her when she was found dead in a creek. Second was the death of two girls Kati and Kristin Lisk. They found some dark…

of composites in sporting goods. Because of exceptional combination of properties as composites offered they are widely used by professional players to get better results. Mainly Carbon fiber reinforced (CFRP) and Glass fiber reinforced plastics (GFRP) are of much interest in sporting industry. How carbon fibers are produced is presented here. This report has also included 3 sports goods. Racing boats, racing bicycle frames and tennis rackets. Short outline is presented here on these 3 products.…

the relationship between distribution of muscle fiber type and performance. How might exercise training modify or change a person’s fiber-type distribution? Muscle fibers can be categorized into two main properties, twitch and metabolic properties. The twitch properties consist of slow and fast twitch and metabolic properties consist of oxidative, oxidative/glycolytic and glycolytic (Beardsley, 2017). Slow twitch and fast twitch muscles fibers are found in all muscles, but one may be more…

or muscle fiber responds to a stimulus is independent of the strength of the stimulus. If that stimulus exceeds the threshold potential, the nerve or muscle fiber will give a complete response; otherwise, there is no response. It was first established by the American physiologist Henry Pickering Bowditch in 1871 for the contraction of heart muscle. According to him, describing the relation of response to stimulus, “An induction shock produces the muscle at the time. “The individual fibers of…
