The practicality of parallel foil windings assembled on medium frequency transformers (MFTs) is analyzed and experimentally verified. efficiency improvement in case equal current sharing contrast to single numerically validated. presence circulating currents between investigated using the impedance matrix where impedances are computed. For experimental validations, an MFT prototype with manufac...

The generalization of the area theorem is derived for case a pulse circulating inside ring laser cavity. In contrast to standard theorem, which valid single pass traveling through resonant medium, obtained generalized takes into account medium-assisted nonlinear self-action effects medium excitation left by at previous round-trip in was then applied theoretical description dynamics single-secti...

BACKGROUND We previously described a primitive cell population derived from human circulating CD14(+) monocytes, named monocyte-derived multipotential cells (MOMCs), which are capable of differentiating into mesenchymal and endothelial lineages. To generate MOMCs in vitro, monocytes are required to bind to fibronectin and be exposed to soluble factor(s) derived from circulating CD14(-) cells. T...

In mammals, phosphocalcic and bone metabolisms are mainly regulated by parathyroid hormone, parathyroid hormone-related peptide (PTHrP) and 1α,25-dihydroxyvitamin D or calcitriol. In camels, circulating levels of calcitriol are 10 times higher than those determined in other ruminants and further increase during early lactation. Calcitriol and parathyroid-related peptide stimulate intestinal abs...

The paper first discusses the real fluids circulating in the earth’s crust, and justifies the need to examine the natural convection in a porous medium of a simple pure fluid with properties resembling those near the thermodynamic critical point. The literature on natural convection in a homogenous porous medium between isothermal horizontal plates, the lower one hotter, is then reviewed. Resul...

the effects of natural zeolite as a bed medium in increasing lettuce and red tilapia growth as well as improvement of water quality parameters in an aquaponic system were investigated. an experiment with a completely randomized design was run with two treatments in triplicates, 1) an aquaponic system without use of zeolite as a control group and 2) use of a small cotton bag, containing 10 g zeo...
