The bio-degradable vegetable oil based nonionic surfactants are generally used in the oil and petrochemical industry.This publication considers two combinations of various surfactants applied in enhanced oil recovery (EOR).The polymer-surfactants solutions prepared by mixtures of two types of nonionic Tilt Switch surfactant and an anionic surfactan

The PAV strain of barley yellow dwarf virus (BYDV) is one of the causal agents of yellow dwarf disease in cereals.The use of germplasm resistant to BYDV is generally regarded as the most effective means of controlling damage caused by this pathogen.In field trials, response to infection with a barley yellow dwarf virus of selected wheat cultivars r

To date, several independent methods and algorithms exist for exploiting constraint-based stoichiometric models to find metabolic engineering strategies that optimize microbial production performance.Optimization procedures based on metaheuristics facilitate a straightforward adaption and expansion of engineering objectives, as well as fitness func

A miniature hair clip set-up presented to the first author gave inspiration for this study.After a number of studies investigating what is haptically perceived as parallel on horizontal, UMBRELLAS frontoparallel or midsagittal planes, the present study focusses on what is felt as parallel behind your head.The results show convincingly that also in
