in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...

  Background: Geographic tongue is usually an asymptomatic inflammatory disorder of unknown etiology that affects the epithelium of the tongue. The cause of the disease remains obscure. Patients with an allergic background such as a personal of family history of asthma, eczema, and hay fever, of an elevated total serum immunoglobulin E level may be more likely to have a geographic tongue. The p...

Background and Aim: Geographic tongue (GT) is a relatively common lesion which is usually asymptomatic and found during routine examinations. Lesions may be single or multiple and frequently are confined to the dorsal surface and lateral borders of the tongue. Although the cause is unknown, zinc deficiency has been suggested as a possible etiologic factor. The purpose of the present study was t...

in this work, the radial distribution function (rdf) of h2 adsorption on coronene (c24) and its si substituted forms was investigated by monte carlo method. the effect of number and position of silicon substituent on the coronene (c24) was compared. the maximum value of rdf at 298 k and 0.1 mpa is 4.34 for 18 si, a structure at 0.73 å. on the basis of results, the coronene with 18 si can be sug...
