Deformation

Key Question The key question for this research project is: what is the relationship of earthquakes and volcanoes along the Mid-Atlantic Ridge compared to Iceland? Introduction Iceland is located over the Mid-Atlantic Ridge between the North American Plate and the Eurasian Plate, and is an example of a mid ocean ridge seen on land. Iceland has divergent and transform plate boundaries, which are also seen along the Mid-Atlantic Ridge. The North American plate, with respect to the Eurasian…

ABSTRACT Flakiness & Elongation index is one of the most prominent criteria that govern behavior and performance of aggregate in the bituminous mixes. The strength and serviceability requirements of bituminous mixture such as Stability, Flow, Voids in Total mix (VTM), Voids Filled with Bitumen and (VFB) highly depend on the physical properties of aggregates. This study conducted by observing the effect of flakiness & elongated index by adding different percentages from 0% to 50% of flaky &…

The Tigers Alive “Some birds are not meant to be caged, that's all. Their feathers are too bright, their songs too sweet and wild. So you let them go, or when you open the cage to feed them they somehow fly out past you. And the part of you that knows it was wrong to imprison them in the first place rejoices, but still, the place where you live is that much more drab and empty for their departure.” ― Stephen King, Rita Hayworth and Shaw shank Redemption: A Story from Different Seasons The…

Babies are not born with the ability or knowledge of how to move their bodies, besides a few instinctual reflexes that they use to survive the beginning days and weeks of life. This is due to their new environment outside of the womb which includes gravity, a factor that a newborn infant has not been exposed to until birth, along with the fact that an infant 's muscles are still developing (Meyerhoff, 2016). Therefore, they are dependent on those around them to move and adjust their bodies for…

A review of Methanoculleus: a hydrogenotrophic methanogens frequently observed in anaerobic habitats Summary: Keywords: Methanoculleus, hydrogenotrophic pathway, methane production Introduction: Methane is an important greenhouse gas due to its capability of retaining heat and its release from many nature sources, including wetlands, fresh water or sea water sediments, and animal manure, etc. There are two main means of atmospheric methane production, biogenic and abiogenic. Since 70%-80% of…

When I was 12 years old, my mother discovered that I had an unusual curve on my back. Worried, she took me to an orthopedic specialist and I was then diagnosed with scoliosis. Scoliosis is a musculoskeletal disorder, and according to scoliosis specialists, it is “the most common spinal deformity among adolescents” (Pialasse and Simoneau 131). More than 7 million people in the United States are affected by scoliosis, 80% of them being idiopathic (“Scoliosis” para.1). Since ancient times,…

The role of circadian rhythms and clock genes in cutaneous wound healing Introduction The governing of rhythmic changes involved in daily behaviour and/or physiology is controlled by light/dark cycles. The field of Chronobiology encompasses biological timings (hormone secretion, blood pressure, reproductive cycles, body temperature, sleep, locomotor activity). Circadian rhythms have been discovered to play a major role in the mental, physical and behavioural changes, which follow a 24 hour…

Bouncy balls are made up of Polymers, which are made up of many small units of monomers, that go through the process of Polymerization to become Polymers. People can see such polymers all around them like rubber, wool, silk etc. Polymers have unique properties that allow chemist’s and scientists to mix different types of polymers with each other to form new ones. In the lab Polyvinyl Acetate (PVAc), Polyvinyl Alcohol (PVA), and Sodium Borate were used to make and design the bouncy balls. The…

Every year, thousands people get heart valve replacements. There are multiple options for replacement valves that can be generalized as either mechanical or biological. One of the mechanical options from the 1970s and 1980s was the Bjork-Shiley valve, which became infamous because of the controversy surrounding its stress fracture failures. These failures resulted the death of about 400 people, causing the valve to be taken off the market. The decisions made leading to this issue must be…
