The invariance principle of enzyme enantioselectivity must be absolute because it is absolutely essential to the homochiral biological world. Most enzymes are strictly enantioselective, and tryptophanase is one of the enzymes with extreme absolute enantioselectivity for L-tryptophan. Contrary to conventional knowledge about the principle, tryptophanase becomes flexible to catalyze D-tryptophan ...

Wheat (Triticum aestivum L.) was grown in earthen pots containing soil of Balkasar Soil Series (Sandy Loam) in green house at the Department of Soil Science and SWC, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi during Rabi season, 2007. The Crop was treated with two levels of Phosphorus (40 and 80 kg P ha-1 ) in the form of SSP, TSP, NP and DAP. A basal doze of 100 kg N and 60 kg K...

Nitrogen (N) and Phosphorus (P) deficiency is a major yield limiting factor across the globe their proper management plays vital role in optimizing crop yield. This field experiment was conducted to assess impact of soil plant nitrogen N P ratio on growth wheat (Triticum aestivum L.) alkaline calcareous soil. The study consisted various levels (0, 40, 80, 160 kg ha−1 as urea) phosphorus 30, 60,...

A large database of individual farmer field data (n = 4,107) for rice production in the Northwestern Indo-Gangetic Plains India was used to decompose yield gaps and investigate scope reduce nitrogen (N) inputs without compromising yields. Stochastic frontier analysis disentangle efficiency resource gaps, whereas on potential region were retrieved from Global Yield Gap Atlas estimate technology ...

Abstract Cellulose has experienced a renaissance as precursor for carbon fibers (CFs). However, cellulose possesses intrinsic challenges substrate such typically low yield. This study examines the interplay of strategies to increase carbonization yield (ligno-) cellulosic manufactured via coagulation process. Using Design Experiments, this article assesses individual and combined effects diammo...

Genotype, environment and agronomic practices are key determinants of crop growth productivity which important to provide food, feed, raw materials income small holder farmers in Africa. The study was conducted at Crop museum, Sokoine University Agriculture, Morogoro, Tanzania investigate physiological response groundnut calcium phosphorus nutrition among three improved genotypes Mangaka (G1), ...

Continuous microwave-assisted flow synthesis has been used as a simple, more efficient, and low-cost route to fabricate range of nanosized (<100 nm) strontium-substituted calcium phosphates. In this study, fine nanopowder was synthesized via continuous with microwave assistance from the solutions nitrate tetrahydrate (with strontium Sr2+ ion source) diammonium hydrogen phosphate at pH 10 tim...
