The objective of the present work was to estimate the efficiency of moistened wipes in removing beryllium with different solutions including Citranox, Alconox, NaCl 5%, Resolve, and Ledizolv on various types of surfaces such as unpainted metal, wood frames, painted metal, concrete, painted concrete, and Plexiglas from three different occupational settings. Of the three plants that were investig...

The paper is devoted to the analysis of the shape of the swash edge line. Formation of the swash boundary is treated as an interfacial phenomenon. The simplest quantitative characteristic of the roughness of interface is its width w, defined as the root-mean-square fluctuation around the average position. For rough interfaces, the scaling with size of the system L is observed in the form w(L)∝ ...

Lungless salamanders (4.1 g) were exercised on a treadmill enclosed in a Plexiglas respirometer at a range of speeds (0.05-0.24 km/h). O2 consumption (VO2) was determined continuously by open-flow respirometry. At the onset of exercise VO2 increased to a "steady state" in approximately 2-5 min. VO2 (ml O2 X g-1 X h-1) increased linearly with speed (S), VO2 = 2.3 (S) + 0.1 (r2 = 0.74). The minim...

Microtubules are long, proteinaceous filaments that perform structural functions in eukaryotic cells by defining cellular shape and serving as tracks for intracellular motor proteins. We report the first accurate measurements of the flexural rigidity of microtubules. By analyzing the thermally driven fluctuations in their shape, we estimated the mean flexural rigidity of taxol-stabilized microt...

In the present paper a study of the time dependent transonic flow field around a single compressor blade in a Laval nozzle is presented. For the investigation the PIV method has been employed because of its ability to deliver instantaneous flow field information across an illuminated plane with high spatial and temporal resolution. From these instantaneous PIV measurements the mean velocity fie...

Our objectives were to study the loss of heat from ischemic brain and to devise a method of maintaining brain temperature. Reversible forebrain ischemia was induced by carotid clamping and exsanguination in 30 anesthetized and artificially ventilated rats. Rectal, skull, and brain temperatures were measured, confirming previous findings that brain temperature falls by 4-5 degrees C during 15 mi...

My approach is to undertake a series of well replicated experiments on a broad range of zooplanktonic taxa, including copepods, larval fish, larval euphausiids, and ciliates. Our experimental apparatus consists of a series of six columnar tanks equipped with infra-red video cameras that continuously scan the full vertical range (210 cm) of each tank and thereby determine the vertical distributi...

Primary motor cortex (M1) has traditionally been considered a motor structure. While neurophysiologic studies have demonstrated that M1 is also influenced by somatosensory inputs (cutaneous and proprioceptive), the behavioral significance of these inputs has yet to be fully defined in primates. The present study describes differential sensory-related deficits following small ischemic lesions in...

This study aimed to investigate the performance of microbial fuel cell (MFC) for simultaneous bioremediation of slaughterhouse wastewater and sustainable power generation. For the first time, an integrated system of tubular type microbial fuel cell (MFC) was used in this study. The MFC consisted of three concentric Plexiglas tubes; the inner tube was the anaerobic anodic compartment, the mid tu...
