A significant degree of ploughness agricultural lands Ukraine has led to increased erosion and the creation soils varying degrees washout, which leads dehumification contamination with toxic substances. Therefore, purpose study was establish features horizontal migration accumulation heavy metals lead, cadmium, copper, zinc, trace elements boron manganese, radionuclides caesium strontium on pod...

The present study examined the effects of cervical spinal manipulation, a widely applied form of physical therapy, which involves innocuous mechanical stimulation, on heart rate and heart-rate variability, in a cohort of healthy young adults. Using a cross-over treatment design, with a one-week washout period and, in contrast to a sham procedure, the authentic manipulation produced significant ...

A model of two microbial species in a chemostat competing for single resource the presence an internal inhibitor is considered. The four-dimensional system ordinary differential equations. Using general growth rate functions species, we give complete analysis existence and local stability all steady states. We describe behavior with respect to operating parameters represented by dilution input ...

In a prospective randomised trial 76 knees with isolated degenerative changes in the medial femoral condyle of grades 3 or 4 were treated by either arthroscopic debridement (40) or washout (36). All knees were followed up for at least one year and 58 for five years. The mean follow-up time was 4.5 years in the debridement group and 4.3 years in the washout group. At one year 32 of the debrideme...

Effects of furfural on the aerobic metabolism of the yeast Saccharomyces cerevisiae were studied by performing chemostat experiments, and the kinetics of furfural conversion was analyzed by performing dynamic experiments. Furfural, an important inhibitor present in lignocellulosic hydrolysates, was shown to have an inhibitory effect on yeast cells growing respiratively which was much greater th...

We measured the rate of washout of 15O-labeled water generated from labeled oxygen accumulated in brain after bolus [15O]O2 inhalation, and compared the washout with that of labeled water measured with H215O. Contrary to the original expectation, the radioactive water generated from labeled oxygen failed to leave the brain tissue at the rate predicted by exogenous water. Therefore, the use of a...
