bacillus sp. sbs25, a gram positive bacteria isolated from soil was found to be effectivein the biodegradation of natural rubber latex. the products of latex biodegradation were separated from the ether extract by thin layer chromatography. gas chromatography and mass spectrometry showed the biodegradation of the major compound into three simpler fractions with low molecular weights. this was f...

Numerous applications of nanotechnology have been developed to probe the unique mechanical properties of cells. In addition, since biological materials exhibit such a wide spectrum of properties, they offer new concepts for nonbiological biomimetic applications. In this chapter, the viscoelastic properties of a cell and its subcellular compartments are described. First, a qualitative picture is...

treatment protocols with low-level laser (also called ‘soft laser therapy) have been used in health care systems for more than three decades. bearing in mind the suitable sub-cellular absorption and the cellular-vascular impacts, low-level laser may be a treatment of choice for soft tissues. low-level lasers have played crucial and colorful roles in performing periodontal surgeries. their anti-...

for planting fine seeds in cellular trays, an automatic pneumatic seeder was designed, constructed and evaluated. catia software was used to design and analysis the system parts of the seeder. different parts of the seeder, including vibrating seed hopper, vacuum boom, seed picking nozzles, seed tube, pneumatic system and electronic control unit for automation of the seeder, were designed and c...
