Abstract Tillage is the most energy-intensive process and should be aimed at accumulation of humus formation a fertile soil layer. Therefore, development resource-saving technological processes technical means to stop progressive degradation from wind, water erosion reduce operating costs relevant. The gentle cultivation with less energy allows you perform disk implements. cultivator working ex...

The large icy moons of Jupiter formed in a circumplanetary disk (CPD). CPDs are fed by infalling circumstellar gas and dust which may be shock-heated upon accretion or sublimated while passing through an optically thin gap. Accreted material is then either incorporated into moons, falls the planet, lost beyond edge on relatively short timescales. If ices during onto CPD we know there must suffi...

In this article, we present a specific shape of disk laser which is side-pumped by four non-symmetric hollow- ducts. The use of non-symmetric hollow duct based on two goals of the uniformity of the pump light distribution profile and the homogeneity of pump light profile through the disk. First of all we simulated the pump light distribution in the disk by using Monte-Carlo ray tracing method. ...

conclusions the presence of bft gene in b. fragilis isolates wouldnot certainly result in diarrheaamong patients. there is not enough accordance between ddm and swedish e tests for antimicrobial susceptibility of b. fragilis for some antibiotics, although in other cases a good agreement was observed. background enterotoxigenic bacteroides fragilis (etbf) are one of the most important anaerobic ...

background and objective: pseudomonas aeruginosa has become a frequent cause of nosocomial infections, particularly in intensive care units (icus). many reports have documented high rates of resistance in this species to commonly-used broad-spectrum antibiotics. the aim of this study was to assess the in vitro activity of some antibiotics against pseudomonas aeruginosa strains to determine the ...
