The difference in temperature between the of basin water and glass cover is most important regulating factor for getting yield from a solar still. higher differential, more distillate still produces. This can be enhanced either by increasing decreasing or combining both strategies together. A strategy lowering to cool it with air flowing water. Cooling not only boosts production but also cleans...

We study the vertex cover problem on finite connectivity random graphs by zero-temperature cavity method. The minimum vertex cover corresponds to the ground state(s) of a proposed Ising spin model. When the connectivity c > e = 2.718282, there is no state for this system as the reweighting parameter y, which takes a similar role as the inverse temperature β in conventional statistical physics, ...

Clinical mycology laboratories now prepare fewer tease mounts of filamentous fungi but increasingly use a variety of tape touch or Scotch Tape methods to microscopically study molds. Mounts are often prepared with clear cellophane tape by a procedure similar to that described in Larone’s Third Edition of Medically Important Fungi: a Guide to Identification (1). Because it is not the most common...

Wildlife residing in urban landscapes face many human-related threats to their survival. For birds, collision with glass on manmade structures has been identified as a major hazard, causing hundreds of millions of avian fatalities in North America every year. Although research has investigated factors associated with bird-glass collision mortality at buildings, no prior studies have focused on ...

A simple, fast, and inexpensive masking technology without any photolithographic step to produce glass microchannels is proposed in this work. This innovative process is based on the use of toner layers as mask for wet chemical etching. The layouts were projected in graphic software and printed on wax paper using a laser printer. The toner layer was thermally transferred from the paper to clean...

Early detection and isolation of circulating tumor cells (CTC) can enable better prognosis for cancer patients. A Hele-Shaw device with aptamer functionalized glass beads is designed, modeled, and fabricated to efficiently isolate cancer cells from a cellular mixture. The glass beads are functionalized with anti-epidermal growth factor receptor (EGFR) aptamer and sit in ordered array of pits in...

In this work the critical aspects of the process sequence developed for fabrication of hybrid polymer microfluidic systems integrating metal electrode pattern and precisely aligned microfluidic structure are discussed in details. Glass and polycarbonate were considered as primary transparent substrate materials for metal (Au, Pt) electrode deposition and the microchannels were formed in multi-l...

purpose: to determine the prevalence of refractive errors and rate of need for spectacles in students of region one in mashhad, 2006. methods: by randomized cluster sampling, 2510 students were selected and underwent eye exami-nations including refraction (cycloplegic, manifest), visual acuity, cover test and determination of the spectacle prescription as well as best corrected visual acuity. e...
