Background & Aims: One of the most common causes of infertility in women is ovarian causes, especially polycystic ovary syndrome (PCOS). However, in patient with PCOS, the number of oocytes taken increased during the IVF, but these oocytes have often low quality, which ultimately leads to reduce fertilization potential. The aim of this research was investigation of PCOS on oocytes quality and p...

Leaves from in vitro proliferating shoots of cvs. Chandler and Hartley of Persian walnut were cultured on MS and NN media supplemented with BA and NAA. Three light conditions including darkness, low light intensity and modified light intensity were used. Most of the calli were friable and non-embryonic in all three conditions. Rate of callogenesis depended on cultivar, culture medium, light con...

In this paper, a new actuator fault detection and isolation method for a four wheel independent drive electric vehicle is proposed. Also, a controller based on sliding mode control method is proposed for lateral stability of the vehicle. The proposed control method is designed in three high, medium and low levels. At the high-level, the vehicle desired dynamics such as longitudinal speed refere...

The unique properties of air-cooled bainitic steels have been described. A series of Mn containing air-cooled bainitic steels invented by authors is presented in this paper: including low carbon granular bainitic steels, low carbon grain-boundary allotriomorphic ferrite/granular bainite duplex steels, medium and medium high carbon bainite/martensite duplex steel, and low carbon carbide free bai...

The amount of digital video and associated metadata being generated and stored is increasing rapidly. Given the complex spatial and temporal structure of video information it is a formidable challenge to provide compact and human-readable representations of such content. The solution has to be versatile in order to satisfy different user needs, such as browsing, zooming (looking for something s...

prioritization of sub-watersheds is very important in the natural sources and watershed management. in this study, the morphometric parameter and landuse changes using rs and gis techniques used in order to identify erosion-prone sub-watersheds. the morphometric parameter such as basin relief, the linear parameters (drainage density, bifurcation ratio, length of overland flow, stream frequency ...
