By using binary ethanol/water mixtures, the separation performance of two improved commercial pervaporation embranes (PERVAPTM) are presented. Separation performance data are analyzed and compared as a function of operating conditions. The effect of initial feed concentration on the separation performance and the effect of feed concentration on apparent activation energy are presented. For memb...

“Testosterone boosters” (TB)—are supplements that are claimed to increase testosterone levels in the human body. While consumption of TB may be popular among athletes, there is insufficient evidence both about safety and real efficacy TB. In our review, we searched MEDLINE/PubMed Cochrane Library for studies on effects 15 substances Anacyclus pyrethrum; Bulbine natalensis; Epimedium (horny goat...

We summarize here the main characteristics of a novel model of pulmonary hypersensitivity. Mice were immunized with a subcutaneous implant of a fragment of heat solidified chicken egg white and 14 days later challenged with ovalbumin given either by aerosol or by intratracheal instillation. This procedure induces a persistent eosinophilic lung inflammation, a marked bone marrow eosinophilia, an...

The purpose of the present study is to investigate the boundary layer separation point in a magnetohydrodynamics diffuser. As an innovation, the Re value on the separation point is determined for the non-Newtonian fluid flow under the influence of the non-uniform magnetic field due to an electrical solenoid, in an empirical case. The governing equations include continuity and momentum are solve...

Epistemic modality serves to indicate how confident language users are about the truth of the ideational material they convey; it is often subdivided into two types of markers, hedges and boosters. Hedges are linguistic devices like perhaps, I guess, and to a certain extent that speakers employ to reduce the degree of liability or responsibility they might face in expressing the ideational mate...

Two launch vehicle concepts based on technologies available today or in a short term future in Western Europe are presented. The design of both launchers has the goal of exploiting synergies with current European programs to limit development and operational costs. Technologies of particular interest here are the high performance solid rocket motors with carbon-epoxy filament wound monolithic m...
