Vapor degreasing uses a partially full container of cleaner heated to its boiling point. The parts to be cleaned are suspended in the vapor cloud above the boiling liquid. The vapor condenses on the cooler parts, dissolves the contaminants and flushes the liquid mixture back into the hot liquid. When the cleaning process is complete, the parts are removed from the tank and they quickly dry in t...

To determine the prevalence and seasonal variation of Psoroptes ovis (Delafond, 1858) mange in goats in the semiarid region of Paraíba, 541 crossbred goats of both sexes and different ages were examined between June 1999 and May 2001 and between August 2011 and December 2012, by washing their ear canals. The monthly prevalence of the infestation varied between 66.66% and 100% without significan...

100% dry assembly using shape matching and van der Waals attraction for parts transfer has been performed to achieve high density parts packing (up to 92%) of thermoelectric cooling components. The feasibility of this approach has been examined for component sizes across a range of 130800μm.

Two-dimensional (2D) layered materials have attracted significant attention for device applications because of their unique structures and outstanding properties. Here, a field-effect transistor (FET) sensor device is fabricated based on 2D phosphorene nanosheets (PNSs). The PNS sensor exhibits an ultrahigh sensitivity to NO2 in dry air and the sensitivity is dependent on its thickness. A maxim...

We examined the oxygen and hydrogen isotopic ratios of surface waters and groundwaters in the catchment of Laguna Lake, Republic of the Philippines, to identify the types of water that combine and control these ratios in the lake water. The oxygen and hydrogen isotopic ratios of water samples collected from rivers, lakes, springs, and irrigation canals were determined using cavity ring-down spe...

The present study documents a simultaneous production and comparative assessment of extracted vasicinone from in vivo (leaves and stems) and in vitro (leaves, stems and calli) plant parts of Adhatoda vasica Nees, a well-known medicinal plant. High-performance thin layer chromatography (HPTLC) analysis of the above-mentioned plant parts, collected at their 60-day-old growth stage, was performed ...

Future changes in the number of dry days per year can either reinforce or counteract projected increases in daily precipitation intensity as the climate warms. We analyze climate model projected changes in the number of dry days using 28 coupled global climate models from the Coupled Model Intercomparison Project, version 5 (CMIP5). We find that the Mediterranean Sea region, parts of Central an...
