Since Darwin first published his groundbreaking theory of evolution, the origin of life has long been a controversial topic for scholars. For theists, they hold the idea that Darwin’s evolution theory fails to explain how first living organism comes from. They believe that failure to show how the fist living organism occurs implies that there is a creator for life who is God. However, the naturalists such as Miller and Haldane shows that chemicals can react each other and form amino acid and…

In this study, we use the modified organo nanoclay as a new sorbent for separation and preconcentration trace amounts of Au(III) in aqueous solutions. Nanoclay was modified with 5-(4'-dimethylamino benzyliden)-rhodanine. Modified nanoclay was used as a solid sorbent for separation and preconcentration trace amounts of Au(III) ions. The sorption of gold ions was quantitative in pH range of 2.0 to 6.0, whereas quantitative desorption occurs instantaneously with 6.0 mL of 1.0 mol L-1 Na2S2O3. The…

Koutsomichalis et al (2008) discussed that having high hardness and good adhesion with the substrate the sprayed coating exhibited satisfactory wear resistance. Tungsten carbide is an advanced ceramic material combining a unique set of properties such as high hardness, high melting point, wear resistance, good thermal shock resistance, thermal conductivity and good resistance against oxidation. They can be applied as coatings by thermal spraying processes such as plasma-spraying, high-velocity…

This particular process involves a surgery which is performed under general anaesthesia. Besides, there are electrodes which are inserted into the affected brain areas according to the symptoms that are being treated. Deep Brain Stimulation (DBS), like other forms of mental stimulation, has numerous positive effects on the Alzheimer patients. This is particularly…

Aerobic Fitness Laboratory Report Ethan C. Bagwell University of Arkansas Introduction The problem addressed in this laboratory report is aerobic fitness and its association with cardiovascular disease and all cause mortality. Aerobic fitness is related to the ability to perform large muscle, dynamic, moderate to vigorous intensity exercise for prolonged periods of time (Thompson, Gordon, & Pescatello, 2014). Aerobic fitness has been considered a health-related part of physical fitness due to…

Introduction Silver, like gold, is found in a native state; frequently too it occurs as an alloy containing gold, which is recognized, when the silver is dissolved in nitric acid, as the black sediment or oxide of gold. Arsenic and antimony are found also alloyed with it. Several of the ores of lead and copper contain silver. As silver is a precious metal often used for coins, its mining has historically often been lucrative. As with other precious metals such as gold, newly discovered deposits…

A Closer Look at Spasmodic Dysphonia Approximately 7.5 million Americans suffer from a voice disorder (NIDCD). Voice disorders are speech disorders characterized by irregular pitch, loudness, duration, and vocal quality that are inappropriate for an individual’s age or gender (ASHA-Def of communication disorders and variations). Voice disorders are broken into three categories: functional, organic, or both. Organic voice disorders are broken down even further into structural and…

Milgram’s (1974) empirical study of obedience is of paramount influence within experimental social psychology. Milgram (1974) was notorious for his fascination with the perils of group behaviour and blind obedience to authority, and aspired to facilitate understanding surrounding human ability to act inhumanely, without boundaries or any apparent conscience, with specific interest surrounding the horrendous acts committed during the Holocaust (Mastrioanni, 2002). Milgram’s (1974) experiment is…
