heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

This study was carried out to understand how land use patterns influence surface water quality in Tien Giang Province using remote sensing and statistical approaches. Surface data were collected at 34 locations with the frequency of four times (March, June, September, November) 2019. Water parameters used analysis, including pH, temperature, electrical conductivity (EC), total suspended solids ...

This study examined nutrient, water and carbon cycling processes and biodiversity patterns within replicated sub-watersheds that comprised different configurations of annual and perennial plant communities, ranging from conventional row crops to mixed annual and perennial systems to reconstructed native plant

This paper examines the effect of conflict on agricultural production of small-farmers. First, we develop an intertemporal model of agricultural production in which the impact of conflict is transmitted through two channels: violent shocks and uncertainty brought by conflict. The model shows how conflict induces sub-optimal agricultural decisions in terms of land use and investment. We test the...

BACKGROUND Turfgrass species are agriculturally and economically important perennial crops. Turfgrass species are highly susceptible to a wide range of fungal pathogens. Dollar spot and brown patch, two important diseases caused by fungal pathogens Sclerotinia homoecarpa and Rhizoctonia solani, respectively, are among the most severe turfgrass diseases. Currently, turf fungal disease control ma...

Plant viruses are important limiting factors in agricultural productivity. Tospovirus is one of the severe plant pathogens, causing damage to economically important food and ornamental crops worldwide through thrips as vectors. Database application resources exclusively on this virus would help to design better control measures, which aren't available. SeeHaBITaT is a unique and exclusive web b...

The molecular genetic mechanisms underlying fruit size remain poorly understood in perennial crops, despite size being an important agronomic trait. Here we show that the expression level of a microRNA gene (miRNA172) influences fruit size in apple. A transposon insertional allele of miRNA172 showing reduced expression associates with large fruit in an apple breeding population, whereas over-ex...
