Capture search, an expensive part of any chess program, is conducted at every leaf node of the approximating game tree. Often an exhaustive capture search is not feasible, and yet limiting the search depth compromises the result. Our experiments confirm that for chess a deeper search results in less error, and show that a shallow search does not provide significant savings. It is therefore bett...

background: maxillary sinuses are covered by a 1 mm thick mucous membrane that when this membrane becomes infl amed, the thickness may increase 10-15 times. the common causes of odontogenic sinusitis are dental abscesses and periodontal disease. computed tomography (ct) is considered the gold standard for sinus diagnosis. recently, cone beam computed tomography (cbct) has been introduced for de...

Functional trait composition of plant communities has been proposed as a helpful key for understanding the mechanisms of biodiversity effects on ecosystem functioning. In this study, we applied a step-wise modeling procedure to test the relative effects of taxonomic diversity, functional identity, and functional diversity on macrophytes community productivity along water depth gradient. We samp...

Present study was conducted to evaluate the cardioprotective activity of Pandanus odoratissimus leaf extract in rats. 24 Sprague – Dawley rats were used in the study and divided in to 4 groups of 6 each. Isoproterenol (85mg/kg,ip) was used to induce the myocardial infarction in rats. Lipistat (350mg/kg) was used as reference control and 200mg/kg of ethanolic leaf extract of Pandanus odoratissim...

cercis siliquastrum is compatible to soil types and has resistance to climate changes. therefore the study of its germination and growth condition can lead us to correct use for semi-arid lands in iran. in this research the effect of different treatment on cercis siliquastrum germination and growth indices was investigated and the most effective treatment was distinguished. thus, five frequenci...

OBJECTIVES To investigate the anatomic limitations of the endoscopic transcanal approach to sinus tympani (ST), in particular, how this approach might allow a complete visualization of the ST recesses and to propose a morphologic classification of the ST using computed tomography and to examine if this could be useful for the surgeon in preoperative planning to decide the type of approach to th...
