Background: Bioenergy attracts much attention due to the global demand for renewable and sustainable energy resources. Waste biomass feedstocks—date pits, coffee waste, cow dung—require efficient environmentally friendly waste-management technologies such as pyrolysis. Fast pyrolysis occurs at fast heating rates (10–100 °C/s), generates high bio-oil yields, is most widely used process biofuel g...

lip pits are among the rarest congenital deformities recorded. initially reported in 1845, it’s familial occurrence has been reported just once. these developmental anomalies occur either as an isolated defect or in association with other developmental deformities including cleft lip, cleft palate or both. it may be located at the commisures of the lips or in the midline of the lower lip. it is...

This work presents the principle of optimal model truck selection for waste transport at open pit Gacko. The analysis was performed three types trucks: Belaz 7555, 75491 and 75135. Selection done using AHP method from group multicriteria decisionmaking methods. results technological procedure Gacko evaluation most important criteria an type selection. In assessment degree their impact, a questi...

Background Anaerobic (absence of air or oxygen) bacteria play an important role in breaking down the hog waste (urine, feces, wasted feed, etc.) into simpler organic and inorganic compounds in the pits and lagoons. However, this also results in the production of many organic gases, also called volatile organic compounds (VOCs) as well as inorganic gases (e.g., ammonia, hydrogen sulfide). Many o...

A 53-kDa protein from the outer sheath of the oral spirochete Treponema denticola was purified to homogeneity and shown to reconstitute channels in black lipid bilayer model membranes. The channel had a single-channel conductance of 1.8 nS in 0.1 M KCl, making this the largest porin channel observed to date (estimated diameter, 3.4 nm). Electron micrographs of 53-kDa-protein-containing outer sh...

Thousands of confined animal feeding operations (CAFOs) have been constructed in eastern North Carolina. The fecal waste pit and spray field waste management systems used by these operations are susceptible to flooding in this low-lying region. To investigate the potential that flood events can lead to environmental dispersion of animal wastes containing numerous biologic and chemical hazards, ...

Treatment methods are presented that can be used for nutrient recovery from animal manure and these processes are compared to the current practice. Using swine feeding operations as an example, the current practice for waste handling is that 97% of all produced waste is applied to owned or rented land after storing the waste in below-floor slurry pits or anaerobic lagoons without cover. This cu...

Biochar from waste has emerged as a vital solution for multiple contemporary issues. While the organic content and porous structure of biochar have granted it benefits. Where use is proven to be beneficial enhancing soil water nutrients retention ability, therefore, saving boosting yields in arid regions. Moreover, capable sequester carbon atmosphere permanently store within soil. As such, this...
