although in the recent years, the effect of ground water level on radial growth of black alder has attacked attentions of scientist but to comprehensively interpret the results of such studies, we need to investigate the independent influence of climate on ring width and other wood anatomical features of this species. hence, in current study, the influence of climatic factors on the annual ring...

In this research, the impact of shoulder width and geometry of gas channel with different structures on proton exchange membrane (PEM) has been investigated using numerical method. 3D, non-isothermal was used with single straight channel geometrywhile maintaining the same boundary conditions and reaction area with addition of humidification for anode and cathode. Our study showed that an ellipt...

(Received) We give an equation satissed by the generating function for parallelogram polyominoes according to the area, the width and the number of left path corners. Next, we give an explicit formula for the generating function of these polyominoes according to the area, the width and the number of right and left paths corners.

purpose : to evaluate the correlation between inner segment/outer segment (is/os) line and external limiting membrane (elm) layer integrity at foveal center and visual outcome and to investigate the prognostic factors in optical coherence tomography (oct) that related to final visual acuity (va) and recovery time in acute central serous chorioretinopathy (csc) methods : we prospectively studied...

This study examines the osteological changes in the hands and fingers of rock climbers that result from intense, long-term mechanical stress placed on these bones. Specifically, it examines whether rock climbing leads to metacarpal and phalange modelling in the form of increased cortical thickness as well as joint changes associated with osteoarthritis. This study also attempts to identify spec...

The aim of this study was to assess by means of cone-beam computed tomography (CBCT) scans the transverse effects on the nasomaxillary complex in patients submitted to rapid maxillary expansion (RME) using Haas expander in comparison to untreated individuals. This prospective controlled clinical study assessed 30 subjects (18 boys and 12 girls) with mixed dentition and during pubertal growth. T...
