We present results from laboratory experiments in a wave flume with and without a sediment bed to investigate the turbulent structure and sediment dynamics of wave-supported mud layers. The presence of sediment on the bed significantly alters the structure of the wave boundary layer relative to that observed in the absence of sediment, increasing the TKE by more than a factor of 3 at low wave o...

The role of olfactory cues such as carbon dioxide, pheromones, and kairomones in bed bug, Cimex lectularius L. behavior has been demonstrated. However, the role of vision and mechanoreception in bed bug behavior is poorly understood. We investigated bed bug vision by determining their responses to different colors, vertical objects, and their ability to detect colors and vertical objects under ...

the decolorization of maxilon-red dye by kissiris immobilized phanerochaete chrysosporium in the trickle-bed reactor (tbr) using the basal nitrogen-limited growth medium was studied. the influence of the superficial liquid velocity (slv) on the decolorizing ability of the fungus was examined at four slvs (cm sec-1): 0.05, 0.075, 0.1, and 0.15. maximum level of the decolorizing activity was abou...

Several transitions of Lower to Middle Turonian pelagic marl–limestone-cycles into Oceanic Red Beds were studied at high resolution to gain a better understanding of the Tethyan marine system before and during red bed initiation and development. Samples were analysed for mineralogy, geochemistry, and stable isotope composition. In particular, carbonate geochemistry of diagenetically largely una...

red beds, conglomerates and salt were considered azoic and problematic rocks, but paleopalynology and inorganic geochemistry proved to be useful for placing them in time and space. in the early last century, in mexican ne region, only three mesozoic red bed units were differentiated, dated as late triassic to late jurassic. it was important tratigraphically to place them properly as they were c...

In (Part I), it was stated that red beds, conglomerates and salt were considered azoic and problematic rocks, but Paleopalynology and Inorganic Geochemistry proved to be useful for placing them in time and space. In the early last century, in Mexican NE region, only three Mesozoic red bed units were differentiated, dated as Late Triassic to Late Jurassic. It was important stratigraphically to p...

Various effects on circulatory functions of light to moderate physical exercise during 4 weeks of bed rest were studied in 6 subjects. During exercise narrow cuffs inflated to 60 ram. Hg were worn on the upper thighs. Changes in plasma volume during and after bed rest paralleled those characteristic of simple bed rest. In contrast to simple bed rest, the major loss of red cell mass was noted at...

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...
