Deflector lofts consist of a 'pinwheel' arrangement of four stationary deflector panels attached to the sides of a cube-shaped cage. These panels are made of wood and Plexiglas and rotate incoming winds in either a clockwise or counterclockwise direction. When released at a distant site, homing pigeons (Columbia livia) raised in deflector lofts exhibit a shift in orientation relative to control...

Because of the aggressive behavior of non-human primates, experimentation on unanes-thetized monkeys requires the use of a restraint system. This paper reports the development of a primate restraining system that maximizes short-term fixation and standardization of head position; this system also provides moderate limitation of body movement. The device consists of a primate chair, which was mo...

The peculiarities of light beam expansion in plasma upon irradiation condensed targets with a powerful UV laser pulse are studied the help mathematical modeling. Experiments were carried out at Lebedev Physical Institute Russian Academy Sciences use GARPUN installation: KrF that irradiated two-layer consisting aluminum foil and plexiglass layer. Channels stretched along direction incidence foun...

In this study, the trace amounts of erythrosine, as a food dye is determined by cloud point extraction-scanometry (CPE-Scanometry) as a new, facile, available, fast, sensitive, and low cost method. The method is based on the CPE of analyte from aqueous solution, diluting the extracted surfactant-rich phase with ethanol, transfer to Plexiglas®cell and scanning the cells containing the...

The vulnerability of periphyton and grazers to current and future levels of ultraviolet radiation (UV) has important ramifications for energy flow in shallow waters. We reduced ambient UV levels in a Tennessee stream with UVopaque Plexiglas suspended over the stream and compared periphyton under these Plexiglas filters to periphyton under UV-transparent polyvinylidene film. The experiments were...

Short-term immobilization leads to fatty muscular degeneration, which is associated with various negative health effects. Based on literature showing very high correlations between MRI Dixon fat fraction and Speed-of-Sound (SoS), we hypothesized that can detect short-term-immobilization-induced differences in SoS. Both calves of 10 patients a calf cast one side for mean duration 41 ± 26 days we...

Recently solution scanometry, as a new, simple, fast, portable, and economic method was introduced for determination of acidity constants of indicator and dyes. In this study, a method was applied for the determination of the acidity constant of p-Rosolic acid (RA) and Bromoxylenol blue (BXB) indicators. The method is based on scanning of Plexiglas® sheet containing colored solutions with a fla...

This article discusses the factors that affect electrical resistance of current spreading grounding device. The issue electrophysical parameters soil its resistivity and consideration such in design devices is considered. It shown keeping moisture near-electrode space electrode, as well maintaining it at a certain level, facilitates improving quality reliability grounding. A relationship has be...
