Results and Discussion A. Diffusion of selected plant pigments In conducting the diffusion of 4 different kinds of treatments (distilled water, distilled water placed in boiling bath, vegetable oil, heated vegetable oil), the researchers made use of the atsuete and sugar beets. The different kinds of treatments determined how the temperature will affect the color intensity of the atsuete and sugar beets. There were 4 test tubes used in each atsuete and sugar beets with each having a…

Diversity, in its broadest definition, and as afforded by Barak (2008), refers to the specific categorization of certain human differences. According to Shore, Chung-Herrera, Dean, Ehrhart, Jung, Randel, & Singh (2009), these differences are what make up the dimensions of diversity such as race, age, gender, disability, ethnicity, and sexual orientation. There is no question as to the fact that there is an influx of diverse populations into the worlds labor market (Groschl, 2012). While the…

Alexander, 2001; Parrish and Falcon-Lang, 2007; Hartmann et al., 2010), and 2) ash from volcanic eruptions buries trees while felled or still upright (e.g., Sigleo, 1979; Witke et al., 2004). The resulting lithic cast forms as the wood’s cell wall components break-down owing to the continuing deposition of silica at a rate and in a manner consistent with maintaining the dimensional…

Introduction This practical consisted of using a microscope on two different types of samples, human hair and Lily pollen to acquire the basics of using a microscope. Three different types of objective lenses were used (4x, 10X and 40X). Furthermore it gave an insight to particulate matter in the air. Q1. Table 1 below shows the diameter of a human hair under previous stated objective lenses Standard deviation is used in this case to quantify the amount dispersal or variation in the results.…

HARDNESS Hardness of a material is most commonly defined as the measure of its resistance to penentration by an indenter.Hardness is also measure of strength and often has the units of stress .The indenter is often fabricated from a hard material such as diamond or hardened steel.The tips of the indenters may be conical,pyramidal,or spherical in shape.The indenter tips may also be relatively small(nano-or micro-indenters) or very large(macroindenters).Since indentation tests are relatively easy…

Population and community-level impacts of feral cats on native fauna have been little studied, but evidence from several studies indicates that direct predation is the most important process involved (reference). Nevertheless, a study was conducted on the stomach contents of 390 feral felines in central Australia, between 1990 and 1994, in the Northern Territory. Felines victualed on a variety of invertebrates, reptiles, birds and mammals, including animals up to their own body mass in size.…

Advancement of medical imaging modalities, such as ultrasound, has significantly helped researchers and health professionals visualise dimensional and morphologic changes within the tendon, such as may occur with overuse injuries amongst athletes. Both Magnetic Resonance Imaging (MRI) and ultrasound have unique benefits and limitations. MRI may be better suited where there is a need for a differential diagnosis while ultrasound can be used to demonstrate active and passive movements in real…

affect soil pH; as calcium levels rise, soil pH becomes less acidic. Calcium exists mainly in the soil as exchangeable cations (Ca2+) associated with basic anions. As the calcium levels increase the associated basic anions neutralize the acidic components of the soil (Gament et al. 2017). We hypothesized that calcium levels in the soil affect species richness; as calcium levels rise in the soil species richness will decrease. As the calcium levels increase, some plants begin to take advantage of…

understanding of their meaning. Hurh (2012) argues that the description of Dupin’s dual nature of “the creative and the resolvent” (Poe, 1841/1975, p.144) alludes to an analytical method called “the regress” (p. 471, 476). This analytical method has two components: composition, which involves “[moving] from the causes to understand the effects,” and resolution, which involves “[moving] from the effects to seek a cause” (Hurh, 2012, p. 476).…
