The pandemic of arsenic poisoning due to contaminated groundwater in West Bengal, India, and all of Bangladesh has been thought to be limited to the Ganges Delta (the Lower Ganga Plain), despite early survey reports of arsenic contamination in groundwater in the Union Territory of Chandigarh and its surroundings in the northwestern Upper Ganga Plain and recent findings in the Terai area of Nepa...
Using theoretical and computational methods we obtain these findings: 1) In micro-confined high-pressure transcritical turbulence, higher than typical levels of vorticity are observed in the viscous sublayer; 2) Flow topologies from far-wall regions vicinity supercritical gas-like wall; 3) Tube-like flow motions favored at scales comparable to density-gradient scale, resulting a smaller number ...
The content of the histamine in most mammalian tissues is very low. Thus , presentation a simple and sensitive method to assay the histamine content in crude extracts tissues is required . In this work ,we presented a simple method for the measurement of the histamine. 2 mg of rat brains was ho...
in the present work a modified in-tube solid phase microextraction technique followed by gas chromatography-mass spectrometry (gc-ms) has been applied for determination of water odorants. geosmin, 2-methyl isoborneol, 2-isopropyl-3-methoxy pyrazine, 2-isobutyl-3-methoxy pyrazine and 2,4,6-trichloroanisol are of the most important odorants which have been studied. in the described method, analyt...
background and aims. the exposure and processing of dental radiographs are not routinely associated with the spatter of blood or saliva; however, infection control is still an issue resulting from contaminated equipment, supplies, film packets or cassettes. this study aimed at comparing the efficacy of four commercially available disinfectants on microorganisms present on the equipment of radio...
Relationships between the micro-architecture description of cancellous bone, obtained from medical imaging, and its mechanical properties can be used to assess the compression fracture risk at high and low strain rate. This study extends the rupture prediction to the intermediate strain rate regime. The micro-architecture description was obtained with a CT-scan, for which geometry, topology, co...
A new disposable micro tissue culture plate was developed and tested for use in virological procedures. Miniature mammalian cell cultures (minicultures) were grown in these plates. Each plate contained 96 circular cultures in flat wells (7 mm in diameter). Replicate titrations of a number of viruses were performed in various tissues. Excellent reproducibility was demonstrated. Mean infectivity ...
Semiconductor micro- and nanotubes can be formed by strain-induced self-rolling of membranes. The effect of geometrical dimensions on the self-rolling behavior of epitaxial mismatch-strained In(x)Ga(1-x)As-GaAs membranes are systematically studied both experimentally and theoretically using the finite element method. The final rolling direction depends on the length and width of the membrane as...
The increase in popularity of “mini” and “micro” behind-the-ear (BTE) devices has been due, in part, to the effective combination of style and substance that appeals to a new generation of hearing aid users. A recent survey by Kochkin (2006) for the Better Hearing Institute indicates that slim tube, “open” fit devices have increased the number of first-time hearing aid users by 29%, lowering th...
We propose highly aligned skeletal muscle fibers (Fig.1). We found that the textiles of a fibrin hydrogel fiber are highly orientated to the the longitudinal direction of the fiber by using a micro fluidic channel of a micro glass capillary tube. We also confirmed that the seeded skeletal muscle cells, C2C12, migrated into the fiber and aligned to the fiber direction without any complex lithogr...
