There are two types of hookworm, Ancylostoma duodenale, known as the Old World hookworm, and Necator americanus, the New World hookworm. While both species may be found in Africa, Asia and the Americas, N. americanus is predominantly located in the Americas and Australia, while only A. duodenale is found in the Middle East, North Africa and southern Europe (a). The origin of the New World speci...

Copper oxide nanoparticles (CuO-NP) are used as an efficient alternative to conventional Cu in agriculture and might end up soils. They show a high toxicity towards cells microorganisms, but only low soil invertebrates. However, most existing ecotoxicological studies were conducted sandy reference at test concentrations ?100 mg Cu/kg soil. Therefore, there is knowledge gap concerning the effect...

Greenhouse experiments were carried out to evaluate the effect of different soil-based countermeasures on radiocesium transfer to Medicago saliva (alfalfa) grown on artificially contaminated loamy-clayey soil. Various rates of potassium, ammonium, and Prussian Blue supplements were applied, and the uptake of radiocesium by control and treated alfalfa plants was monitored during four growth peri...

The mobility of metazachlor [2-chloro-N-(pyrazol-1-ylmethyl)acet-2',6'-xylidide] in sand soil and loamy sand soil was studied in a soil column under laboratory conditions. Commercial metazachlor formulation (Metazachlor 500 suspension concentrate (SC)) and metazachlor immobilized in alginate matrix were used for leaching experiment. The initial concentration of metazachlor in soil for both form...

Analysis of yielding ability and growth patterns of mash bean (Vigna mungo L.Hepper.) genotypes were carried out on loamy sand soil during kharif season. Genotypic differences were observed with respect to extent of flower production/shedding, podding and crop durations. Plants of Mash338 were dwarf, erect, compact with determinate growth habit whereas Mash1-1 were tall, spreading with indeterm...

A computational efficient approach to identify very small mine-shaped plactic objects, e.g. M56 AntiPersonnel (AP) mines buried in the ground, is presented. The size of the objects equals the smallest AP-mines in use today, i.e., the most difficult mines to detect with respect to humanitarian mine clearance. Our approach consists of three stages, the phase stepped-fiequency radar method, genera...
