1. Potentially, how could caffeine work to enhance human performance? Researchers believe that caffeine affects central and peripheral sites during submaximal contractions of varying speeds. Central nervous system activity may be impacted, quieting the sensations of pain and effort. Increased supraspinal motor unit activation accompanied by greater sarcolemmal and fast twitch motor unit excitability may also be elicited.1 The peripheral effects are equally important and focus on intracellular…

CHAPTER – 1 1. INTRODUCTION Carbon nanotubes are allotropes of carbon with cylindrical nanostructure. Constructed with length-to - diameter ratio of up to 132,000,000 :1. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Nanotubes are members of fullerene structural family. Nanotube’s walls are formed by one-atom thick sheet of carbon called Graphene. The combination of…

composed of a TBE IX buffer (0,89M Tris, 0.8M Boique acid, 0.02 mM EDTA; pH 8.4 disodium). The nucleic acids, polyanionic macromolecules uniformly negativemen loads, when placed in a constant electric field will then migrate through the gel towards the anode. The speed of movement of the fragments through the gel mesh will therefore vary depending on the concetration in agarose gel, but also the molecular weight (number of base pairs) of each fragment. The agarose gels allowing separation of…

A. fischeriThe overall purpose of this study was to create a genomic library of Aliivibrio fischeri (A. fischeri) thus aiding in creating a restriction map of the lux operon. It also employs typical molecular techniques important for biologists to understand. In this portion of the lab, the chromosomal DNA (chDNA) will be isolated. Its purity will be measured using spectrophotometric analysis. Lastly, the DNA will be digested and verified via gel electrophoresis. A. fischeri is a gram…

Spray pyrolysis is basically a thermal reaction between clusters of the liquid/vapor-atoms of different chemical species. The spray pyrolysis technique involves spraying of aqueous solution in spray form containing a decomposable salt solution of the constituent atoms. The experimental setup used in the present study is described elsewhere [21]. CdO thin films with different Cr- doping concentrations were deposited on ultrasonically cleaned microscopic glass substrates. The appropriate quantity…

on an agarose gel after performing electrophoresis.[5] For this test, a small sample of DNA that had been isolated was loaded into a well in the agarose gel which was then exposed to an electric field. DNA is negatively charged so moved towards the anode. Due to small fragments of DNA moving faster, the DNA was separated in size. This can be seen in figure 1.

instrument. For measurement of the amount of particle, coulter counter operates by measuring the changes in the current intensity between two electrodes that submerged in the suspension of particles in conducting fluid. The conducting fluid is flow between anode and cathode through a small hole called as orifice. Presence of a particles in the orifice cause changes in resistant. Following the Ohm’s formula: Intensity = Voltage / Resistant. The changes in resistance is also related with particle…

Gel electrophoresis is a method used for separation and analysis of molecules such as DNA, RNA, and proteins, based on their sizes and polarity. DNA (deoxyribonucleic acid) is a molecule that carries most of our genetic information, and possesses a negative charge. During gel electrophoresis, DNA fragments can migrate through the gel also known as agarose when placed in a powerful electrical field. The rate at which the DNA fragments will move through the gel depends on their relative size.…

For every atomic nucleus, its total angular momentum is represented by the symbol I and called its nuclear spin. This spin is then determined by its quantum number, which is represented by the symbol S. Each nuclear spin is associated with a magnetic moment. When this moment is placed in an external magnetic field, these spin states differ in magnetic potential energy. If placed in a static magnetic field with a small amount of spin polarisation however, certain radio frequency signals can allow…

(2013) conducted investigations of copper and selenium recovery from copper anode slimes. The process consisted of two hydrometallurgical steps; decopperization in sulphuric acid media and dissolution of selenium in caustic solution. Temperature caustic concentration, oxygen partial pressure and reaction time were all found to increase…
