-A top-down approach to the determination of grammar engineering methods for the construction of Natural Language Grammars for Question Answering Systems based on Intelligent Text Mining for Biomedical applications is presented in the present paper. Our proposal is to start with the formulation of the ultimate task goal such as specialized question answering and derive from it the specification...

The problem of Dynamic Job Shop (DJS) scheduling is one of the most complex problems of machine scheduling. This problem is one of NP-Hard problems for solving which numerous heuristic and metaheuristic methods have so far been presented. Genetic Algorithms (GA) are one of these methods which are successfully applied to these problems. In these approaches, of course, better quality of solutions...

Schistosoma mansoni do not have de novo purine pathways and rely on purine salvage for their purine supply. It has been demonstrated that, unlike humans, the S. mansoni is able to produce adenine directly from adenosine, although the enzyme responsible for this activity was unknown. In the present work we show that S. mansoni 5´-deoxy-5´-methylthioadenosine phosphorylase (MTAP, E.C. 2.4.2.28) i...

Inteligent hydrogels, such as pH sensitive hydrogels based on poly(methacrylic acid) (PMAA) are widely used for targeted drug delivery. Still, PMAA lack of good mechanical properties often limits its application. In order to overcome this limitation nanocellulose (NC) was extracted from wood waste material and then added because NC is biocompatible, non-toxic has excellent properties. Further, ...

The huge expans ion in the s ize of internet and the appearance of various types of malicious attack and the in s u ffic iency of traditional security tools like antivirus conduct to the development of intrus ion detection sys tems or IDS. Since current IDSs a re s ignature based they s til are unable to detect new forms of attacks even if these attacks are s lightly deriv e d from known ones ....

conclusions this study showed that some properties of antimicrobial substances produced by the ga strain differed from other peptide antibiotics produced by the genus bacillus such as bacitracin, which increases the likelihood of its novelty. results the isolated bacterium was identified as a new strain of bacillus atrophaeus. the antimicrobial substance exhibited heat stability between 25ºc an...

metronidazole, a synthetic derivative of the nitroimidazole class is a known antibacterial and antiprotozoal agent. the hypolipidemic effect of metronidazole was not known. the authors noticed it incidentally for the first time. after quazi experimental studies on several cases, it was revealed that 750 mg of metronidazole for 10 days significantly decreased serum cholesterol. this trial was pe...
