Relationship between epicardial adipose tissue and coronary function evaluated with [13 N]NH3 PET/CT. [PDF]

Int J Cardiovasc Imaging
Abstract Different reports have suggested that epicardial adipose tissue (EAT) is related to impaired coronary function, myocardial ischemia and major adverse cardiac events. The aim of this study was to evaluate whether a relationship between EAT volume (EATvol) and thickness (EATthick) with myocardial blood flow

Ammonia volatilization and yield of corn fertilized with different nitrogen sources in the Brazilian semiarid [PDF]

Pesquisa Agropecuária Brasileira, 2020
: The objective of this work was to evaluate the effect of the use of different nitrogen fertilizers on N losses by NH3 volatilization and on the grain yield of a corn (Zea mays) crop grown in the semiarid region of the state of Sergipe, Brazil. Corn was

Use of urease and nitrification inhibitors to reduce gaseous nitrogen emissions from fertilizers containing ammonium nitrate and urea

Global Ecology and Conservation, 2020
Nitrogen (N) fertilizers increase agricultural yields, but also lead to the release of the greenhouse gases nitrous oxide (N2O) and ammonia (NH3). This not only reduces the efficiency of N use, but also results in climate change and loss of biodiversity.
