In the theory of elasticity as at present accepted' it is assumed that the energy of deformation is a function of the strain components and the various types of crystalline media are distinguished from one another and from an isotropic medium by the form of this function. It is the object of the present note to show that the mere assumption that the energy of deformation is a function of the st...

background: although lowering of food cholesterol is an effective way to reduce blood cholesterol, but recently some effective health and bioactivity characteristics of the milk fat components have been identified, so by decreasing the use of milk fat, an important source of fat-soluble vitamins and bioactive components of milk is limited. recent studies have shown that the growth of lactic aci...

since there is limited information on the simultaneous effect of drought stress and salicylic acid on yield and mucilagecontent of the medicinal herb, plantago ovata forssk is available, a pot experiment was conducted in factorial form basedon a randomized complete block design with three replications in jiroft, kerman province, south of iran. as the firstfactor, drought stress included four le...

The application of iron-silica (Fe-Si) nanoparticles for the enhancement of the Pseudomonas aeruginosa growth and rhamnolipid production in molasses medium was studied. The experiments were designed based on the response surface method (RSM) to optimize growth and rhamnolipid production. The concentration of nanoparticles and the time required to add nanoparticles to culture medium were conside...

background: extensive full-thickness burns require replacement of both epidermis and dermis. in designing skin replacements, the goal has been to re-create this model and make a product which has both essential components. methods: in the present study, we developed procedures for establishing confluent, stratified layers of cultured human keratinocytes on the surface of modified collagen-chito...
