Role of Telomeres in Aging

HoJun Kweon* and HyoJu Kweon Daegu International School, 101-dong 2201-ho, 10, Palgong-ro 53-gil, Dong-gu, Daegu, Republic of Korea Jinkyoung (May) Lee Yongsan International School of Seoul, San 10-213, Hannam 2 dong, Yongsan-ku, Seoul, Republic of Korea Abstract At the ends of eukaryotic chromosomes are telomeres, which play a central role in the protection of genetic data and the enabling of cell division. Telomeres modify the cellular response to growth and stress based on various hereditary […]

Facilitating Biodigester Biogas Production Using a Rumination Model of Bos taurus

Abstract In order to develop resource and time efficient methods of biogas production as an energy source, the biodigestion procedure physically and chemically modified the biodigestion process to mimic the rumination process of Bos taurus. The experimental protocol used manure slurry and the independent variables of a varying mixing times and digestive enzymes to produce biogases. The results demonstrated significant increases in biogas production with both mixing time variation and enzyme additives to manure slurry. […]
