In this paper, a new hybrid concept is proposed by analyzing the principle of the hybrid cryptography based on the combination of symmetric and message digesting. Moreover, the security and performance of the proposed concept will also estimate. In proposed concept we designed a new symmetric encryption algorithm and combine with SHA1 message digesting function to provide hybrid nature. Now the...

The giant panda genome codes for all necessary enzymes associated with a carnivorous digestive system but lacks genes for enzymes needed to digest cellulose, the principal component of their bamboo diet. It has been posited that this iconic species must therefore possess microbial symbionts capable of metabolizing cellulose, but these symbionts have remained undetected. Here we examined 5,522 p...

Temperature is an important factor determining distribution and abundance of organisms. Predicting the impact of warming climate on ectotherm populations requires information about species' thermal requirements, i.e. their so-called 'thermal niche'. The characterization of thermal niche remains a complicated task. We compared the applicability of two indirect approaches, based on reaction norm ...

The effects of some factors on the preparation and regeneration of protoplasts from the taxol-producing fungus Nodulisporium sylviforme were discussed in this paper, including combination of various enzymes, digesting time and temperature, and pH value, osmotic stabilizers, pretreation, culture medium and culture method. Under the condition of the mixed enzymes in osmotic pressure stabilizer (0...

The cooking of food is hypothesized to have played a major role in human evolution partly by providing an increase in net energy gain. For meat, cooking compromises the structural integrity of the tissue by gelatinizing the collagen. Hence, cooked meat should take less effort to digest compared to raw meat. Likewise, less energy would be expended digesting ground meat compared to intact meat. W...

PURPOSE Keratoconus is characterized by thinning and scarring of the central region of the cornea. Previous research showed that, in corneas obtained from patients with keratoconus, lysosomal enzyme activities are elevated, whereas levels of protease inhibitors such as alpha1-proteinase inhibitor are reduced. This study was undertaken to examine further the expression of a spectrum of proteolyt...
