The article studies 22 traits in various genes and identification of the novel relations for the hair morphology. The studies have revealed that most of the human, physical characteristics such as hair morphology can indeed be inherited from the parent organisms. A survey had been carried out for many people, and together with the company’s examinations, participants revealed associations in certain Single Nucleotide Polymorphisms (SNPs). Sheka, Sri N. et al. (2008). Linkage and Association Analysis of Spectrophotometrically Quantified Hair Color in Australian Adolescents: the Effect of OCA2 and HERC. Journal of Investigative Dermatology. 128, 2807–2814. The article provides the results of investigation by the Genetic Epidemiology unit in Brisbane, Queensland, Australia. It shows how the genetic studies of pigmentation have benefited from the spectrophotometric measures of light to dark hair color. The article insists on having accurate reference measurements when carrying out any studies concerning the variations due to the genetic influences. According to the studies, the investigations concerning the hair color have turned to the spectrophotometric measurements, as well as the biochemical quantification. In using spectrophotometric methods, a wavelength of 650nm is used as it has the greatest power to differentiate the different amounts of dermal melanin. The associations were analyzed that the OCA2 and HERC2 to determine the allele difference in various populations. However, the spectrophotometric method cannot be said to be a confirmation therefore, further methods should be carried out to determine the complement of genes infl uencing hair color. The study also should determine if the spectrophotometry has any importance over prepared ratings. The study also quantifies the amount of pigments for the light and dark

Landfill, Civilization, Disposability, Material Culture, Essay - 1

Landfill, Civilization, Disposability, Material Culture, - Essay Example 1 Production of disposable materials is a key concept in waste management. Common waste management practices include decreasing overall waste production, production of disposable materials, use of landfill and recycling. However, use of disposable materials as means of managing waste products has received much criticism from environmentalists.2 For example, recycling of disposable glass bottles, needles and syringes is responsible for spreading HIV, Hepatitis and other viral diseases. In addition to this, production of disposable material has led to dirtying the environment s such material take time to decompose. In addition to this, as the material decompose; they harbor bacteria and other organisms which cause diseases such as cholera. Lastly, disposable materials encourage users to be irresponsible as they throw waste material anywhere hoping it will decompose.3 It is therefore pointless for individuals to rely on disposable products. Instead, they should rely on recyclable materials. For example, shoppers can carry their goods in reusable bags rather than disposable plastic bags. Similarly, hand towels as well as other disposables should be replaced with cloth towel or hand
