trichoderma is a genus of asexually reproducing fungi that is present in all types of soils. trichoderma species have been recognized as antagonists of soil-borne and foliage pathogens and as efficient decomposers of cellulosic waste materials. moreover, they have the ability to increase plant growth and induce plant resistance. along with mycoparasitism, antibiotics and competition, induced re...

background: new treatment modalities are developed with the aim of escalating tumor absorbed dose and simultaneously sparing the normal structures. the use of nanotechnology in cancer treatment offers some possibilities including destroying cancer tumors with minimal damage to healthy tissues. zinc oxide nanoparticles (zno nps) are wide band gap semiconductors and seem to have a good effect on ...

tehran city has been subject of critical environmental challenges during the course of 20th. century namely: massive population growth, broad expansion, reduction in urban open/green spaces, increasing in energy consumption and waste production. releasing industrial wastewater into river valleys have led to considerable changes in structure of city's natural landscape. the natural structur...

This paper studies joint security and robustness enhancement of quantization-based data embedding for multimedia authentication applications. We present analysis showing that through a lookup table (LUT) of nontrivial run that maps quantized multimedia features randomly to binary data, the probability of detection error can be considerably smaller than the traditional quantization embedding. We...
