Methane (CH4) is the principal constituent of natural gas and is also a potent greenhouse gas (GHG)1. During production of oil and natural gas (O&NG), some processes are designed to vent CH4to the air, and CH4is also emitted unintentionally via leaks in the system. According to the off...

Derivatives of 2-aminofluorene (4), 4-amino-trans-stilbene (7) and p-toluidine (6) as well as 4-dimethylaminodibenzyl, p-nitroso- and p-nitrotoluene were tested for genetic activity (induction of mitotic gene conversion) in cells of yeas... H Marquardt,FK Zimmermann,H Dannenberg,... -...
Geo-climatic environmental conditions lead to the formation of gypsum-rich soils which occur in dry condition throughout world where the annual quantity of
(58 potentially functional genes and 84 pseudogenes) and 11 Jλ -Cλ clusters. Phylogenetic analysis suggested the guinea pig’s large germline VH gene segments appear to form limited gene families. Therefore, this species may generate antibody diversity via a gene conversion-like mechanism ...
Initial and final BW, ADG (kg/d), and feeding conversion did not differ between treatments (p > 0.05), averaging 345 kg, 375 kg, 0.99 kg/d, and 7.1 kg/kg, respectively. 3.3. Purine Derivatives, Microbial N Synthesis and Nitrogen Partitioning The effects of pasture treatments on purine...
