The interactions between the assimilation and transport of nitrogen and carbon were investigated in barley and spinach leaves. Both plants were fumigated with NH3 (1 mg m ) and the content of amino acids, sucrose and carbon intermediates of amino acid metabolism were analysed in the leaves, apoplast and phloem sap. The following changes took place in the Cand N-metabolism of barley leaves durin...

In view of the nitrogen and phosphorus non-point source pollution caused by paddy field drainage in southern China, two fields Nanjing Yuyao cities were selected to study effect plant buffer zone–antifouling curtain walls on reducing pollution. The results showed that designed wall systems could significantly reduce concentration total (TN) (TP) fields. Compared with Nanjing, interception rate ...

Gas-permeable membrane technology is useful to recover ammonia (NH3) from liquid manures. In this study, phosphorus (P) recovery via MgCl2 precipitation was enhanced by combining it with NH3 recovery through gas-permeable membranes. Anaerobically digested swine wastewater containing approximately 2300 mg NH4+-N L-1 and 450 mg P L-1 was treated using submerged membranes plus low-rate aeration to...

Metal ions play important roles in chemical and biological systems and its oxidation and reduction processes trigger many catalytic reactions in solution. In these systems, the solvation of metal ions is a key issue to understand the chemical behavior. In order to clarify the microscopic aspect of solvation process under a limited number of solvent molecules, solvated metal ion clusters are con...

Copper(II) complexes, containing aliphatic tripodal tetramine ligand, [Cu(trpn)(NH3)] 2+ (1), [Cu(tren)(NH3)] 2+ (2), [Cu(332)(NH3)] 2+ (3) and [Cu(322)(NH3)] 2+ (4) are optimized at B3LYP/ LANL2DZ and B3LYP/GEN levels of theory in gas phase (where (trpn), (tren), (332) and (322) are N(CH2CH2CH2NH2)3, N(CH2CH2NH2)3, N[(CH2CH2CH2NH2)2(CH2CH2NH2)] and N[(CH2CH2CH2NH2)(CH2CH2NH2)2], respectively)....

the objective of this study was to determine the effects of diets having different fermentability on blood gases, blood metabolites and ruminal fermentation parameters in holstein dairy cows. four multiparous holstein dairy cows (665 ± 25 kg bw, 170 ± 7.0 dim and 15±1.5 kg of milk yield), fitted with rumen cannulae, were used in a 4×4 latin square design with 28-d periods. corn starch and sucro...

Nitrogen and organic matter are part of the pollutant causing eutrophication in freshwater. Textiles industry like Endek is main source matter. Tis paper aims to know degradation process Ammonia-Nitrogen (NH3-N) Chemical Oxygen Demand (COD) with ozone pretreatment operated by different DO level activated sludge. There 2 scenarios treatments this study: (R1) without (R2). Wastewater treatment be...

Abstract. Ammonia (NH3) is an important agent involved in atmospheric chemistry and nitrogen cycling. Current estimates of NH3 emissions from biomass burning (BB) differ by more than a factor 2, impeding reliable assessment their environmental consequences. Combining high-resolution satellite observations columns with network measurements the concentration stable isotope composition (?15N) NH3,...

New waste management methods are needed that can protect the environment and allow manure management to switch back to a recycling view of manure handling. We investigated the use of gas-permeable membranes as components of new processes to capture and recover the ammonia in the liquid manures or in the air of poultry houses and other livestock installations. The basic process includes the pass...
