melamine is a potentially hazardous compound and one of the major concerns especially in dairy products and pet foods. in the present study a sensitive, simple and reliable method for extraction and determination of melamine in infant milk and coffee mate has been developed. this method consists of an initial extraction in buffer media prepared by formic acid and sodium formate, followed by pro...
bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...
Online deception is disrupting our daily life, organizational process, and even national security. Existing deception detection approaches followed a traditional paradigm by using a set of cues as antecedents, and used a variety of data sets and common classification models to detect deception, which were demonstrated to be an accurate technique, but the previous results also showed the necessi...
In structure-based drug design, the relative orientation of two competitive ligands A and B in the receptor binding pocket plays a central role in the design of high-affinity drug candidates from weakly bound lead compounds. In this communication we report on the observation of interligand spin-diffusion-mediated transferred-NOE data, which have the potential to be used for the determination of...
BACKGROUND Production of biofuels from microalgae has been recognized to be a promising route for a sustainable energy supply. However, the microalgae harvesting process is a bottleneck for industrialization because it is energy intensive. Thus, by displaying interactive protein factors on the cell wall, oleaginous microalgae can acquire the auto- and controllable-flocculation function, yieldin...
The physical, chemical and optical properties of nano-scale colloids depend on their material composition, size and shape. There is a great interest in using nano-colloids for photo-thermal ablation, drug delivery and many other biomedical applications. Gold is particularly used because of its low toxicity. A property of metal nano-colloids is that they can have a strong surface plasmon resonan...
Sortase (SrtA), a transpeptidase from Staphylococcus aureus, catalyzes a cell-wall sorting reaction at an LPXTG motif by cleaving between threonine and glycine and subsequently joining the carboxyl group of threonine to an amino group of pentaglycine on the cell wall peptidoglycan. We have applied this transpeptidyl activity of sortase to in vitro protein ligation. We found that in the presence...
Mediated moderation occurs when the interaction between two variables affects a mediator, which then affects a dependent variable. In this article, we describe the mediated moderation model and evaluate it with a statistical simulation using an adaptation of product-of-coefficients methods to assess mediation. We also demonstrate the use of this method with a substantive example from the adoles...
In modern master slave system, which have computer mediator between the two sides, the mediator computer faces high and non deterministic computational load arising from complex problem of computing instantaneous physical distances of moving robot from the modeled objects in the workspace. The problem is acute for mediators that work in pre-contact state where tool-tip is in close vicinity to o...
