The potential energy surface of an off-lattice model protein is characterized in detail by constructing a disconnectivity graph and by examining the organisation of pathways on the surface. The results clearly reveal the frustration exhibited by this system and explain why it does not fold efficiently to the global potential energy minimum. In contrast, when the frustration is removed by constr...

humans are born with potential abilities which may emerge due to certain circumstances. in educational environments, needs, interests and capacities of individuals are wide and varied. therefore, developers and educators of training programs must provide special facilities to identify talented people in the way that justice is observed for all people. meanwhile, there is no doubt that technolog...

cancer patients are more susceptible to adverse drug-drug interactions (ddis) due to receiving multiple medications especially chemotherapy medications, hormonal agents and supportive care drugs. the aim of this study is to describe the prevalence of potential ddis and to identify risk factors for these potential interactions in hospitalized cancer patients in a developing country.a cross-secti...

the antifungal potential of essential oils of thyme (thymus vulgaris l.), rosemary (rosmarinus officinalis l.), and laurel (laurus nobilis l.) was determined. to establish this antifungal potential, two molds related to feed spoilage, namely, aspergillus flavus and aspergillus parasiticus, were selected. the agar dilution method was employed for the determination of antifungal activities. the i...

The Lennard-Jones (LJ) Potential Energy Problem is to construct the most stable form of N atoms of a molecule with the minimal LJ potential energy. This problem has a simple mathematical form

quinones are a class of compounds which have widespread importance in chemistry, biology and medicine. because of their appropriate performance in electron transferring rate, quinones are among the most applicable mediators in biosensors. recently, the effects of different non-metal substitutions on redox potential of quinone have been investigated to design suitable mediators for different ele...
