thirty pairs ovaries of camel from isfahan abattoiry were collected. in each specimen,  some parameters such as  length, width and thickness of left and right ovaries were measured. for histological studies , after tissue preparation  and staining with h&e;, the ovarian follicles were recognized and classified. for each follicle some parameters such as: diameter of oocyte and follicle, thicknes...

One of the most popular forming processes is the shape rolling process in which the desired shape change is achieved by pressing two rollers with a special shape in the opposite rotational direction. In order to improve the product’s quality and reduce production costs, accurate analysis of the shape rolling process of the compressor blades as well as the investigation of the effective paramete...

background and aims. gingival recession (gr), a common problem in periodontium, is associated with various etiologic factors. there is controversy over the role and importance of these factors. the aim of this study was to evaluate the etiologic factors of gr in a group of subjects in northwest iran. materials and methods. in this case-control study, patients referring to a university clinic (1...

in order to investigate the water deficit impact on physical characteristics of seed in four sunflower hybrids (azargol, allstar, hysun 33 and hysun25), under three irrigation regimes (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan, respectively) and experiment was conducted. sampling was done at the end of growing period (season) when the moisture conte...

the autotetraploidy was achieved in basil using tip meristem treatment of seedlings with various concentrations of colchicine solution (0, 0.05, 0.1, 0.2, 0.5 and 0.75% (w/v) ph = 6). a significant increase in the essential oil content was observed in tetraploids as they carry the potential of productivity of 69 % more oil over the diploids. a field experiment was conducted to investigate the e...

cold roll-forming is a process in which the roll of sheet is formed by passing continuously through the set of rotary rollers without changing thickness in a cool way until it is formed to the desired profile. in this paper a parametric study on the section twist angle in roll-forming the non-symmetric channel is presented, using finite element simulation. at first finite element simulation res...

Abstract In hyperbolic geometry there are several concepts to measure the breadth or width of a convex set. first part paper we collect them and compare their properties. Than introduce new concept thickness body. Correspondingly, define three classes bodies, bodies constant with, diameter having shadow property, respectively. We prove that property follows fulfilment both stronger as width. la...

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...
