Perda de amônia por volatilização em pastagem de capim-tanzânia adubada com uréia no verão Ammonia volatilization loss in tanzaniagrass pasture fertilized with urea in the summer

open access: yesRevista Brasileira de Zootecnia, 2004
Parte do nitrogênio (N) do fertilizante aplicado à pastagem pode ser perdida do sistema e, em pastagens tropicais, a volatilização de amônia (NH3) é uma das principais vias de perda.

THE EFFECT OF N-NH3 INCLUSION ON THE DEGRADATION OF TANNIN OF SORGHUM GRAIN BY RUMEN MICROBES [PDF]

open access: yes, 2010
Two experiments were conducted to study the effect of N-NH3 inclusion in the rumen liquor on the degradation of tannin of whole sorghum grain. The first experiment was carried out to determine the effect of N-NH3 inclusion doses in the rumen liquor on ...

Mitigation of ammonia volatilization with application of urease and nitrification inhibitors from summer maize at the Loess Plateau

open access: yesPlant, Soil and Environment, 2018
Field experiments were conducted at three sites: Yangling (YL); Zhouzhi-1 (ZH-1) and Zhouzhi-2 (ZH-2) of the Loess Plateau during summer maize crop, to investigate the effectiveness of N-(n-butyl) thiophosphoric triamide (NBPT) and NBPT + dicyandiamide ...

曝气生物滤池去除二级出水中NH3-N的试验研究

open access: yesGongye shui chuli, 2005
采用曝气生物滤池工艺对燕化公司西区污水处理场的二级出水进行了处理,研究了进水NH3-N浓度、COD浓度、m(COD)∶m(NH3-N)、碱度及气水比对NH3-N去除效果的影响。试验结果表明,当进水NH3-N质量浓度小于30mg/L时,曝气生物滤池对NH3-N具有良好的去除作用,平均NH3-N去除率达到90.4%,出水NH3-N质量浓度可降至1mg/L以下。NH3-N去除率随进水m(COD)∶m(NH3-N)的增加而降低;当进水m(COD)∶m(NH3-N)小于2.0时,NH3-N去除率达到90%以上 ...

Plant uptake of nitrogen adsorbed to biochars made from dairy manure

open access: yesScientific Reports, 2021
The conversion of dairy waste with high moisture contents to dry fertilizers may reduce environmental degradation while lowering crop production costs. We converted the solid portion of screw-pressed dairy manure into a sorbent for volatile ammonia (NH3)

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Significant reduction of ammonia emissions while increasing crop yields using the 4R nutrient stewardship in an intensive cropping system

open access: yesJournal of Integrative Agriculture, 2023
Ammonia (NH3) emissions should be mitigated to improve environmental quality. Croplands are one of the largest NH3 sources, they must be managed properly to reduce their emissions while achieving the target yields.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in
