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

Duromide increase NBPT efficiency in reducing ammonia volatilization loss from urea

Revista Brasileira de Ciência do Solo, 2021
Novel fertilizer stabilization technologies are needed to decrease ammonia (NH3-N) losses and increase nitrogen use efficiency. Duromide + NBPT is a new technology that combines two molecules, Duromide and NBPT, whose propose is to increase the ...

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.

Mathematical models for adjustments in the quantification of ammonia volatilization from urea fertilizer applied on tropical pastures

Ciência Rural, 2023
: In Brazil, urea is the most used nitrogen (N) fertilizer to improve forage production. However, their excessive use can cause environmental impacts through N losses, such as ammonia (NH3) volatilization.

Evaluation of microbial activity, N-NH3 and CO2 losses in poultry litter treated with basalt rock powder

International Journal of Recycling of Organic Waste in Agriculture, 2023
Purpose Poultry litter (PL) and basalt rock powder (BRP) are raw materials highly produced in some Brazilian regions. The association of these products can generate greater added value for the agribusiness chain and be a sustainable source of fertilizer.Method The experiment consisted of an incubation trial over time for chemical characterization of ...

Ruminal pH and N-NH3 behavior: a Bayesian approach

Semina: Ciências Agrárias, 2016
In this work, we present the Bayesian approach as an alternative to frequentist analysis regarding correlated data of pH and N-NH3 in the Holstein cow rumen. It was observed that for pH and N-NH3 data, a posteriori estimates of coefficients of the regression models were significant, which was not observed for least-squares estimates. Thus, the Bayesian
