investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
The intrinsic properties of some materials, such as foams, porous materials and granular materials, are their ability to mitigation waves. In this study, we investigated the ability of granular materials in explosion-induced wave mitigation. The present study was carried out using numerical simulations with Autodyn hydro-code and experimental tests by shock tube. Two materials of sawdust and mi...
طی بررسی تاکسونومیک کنه های پارازیتنگونای خشکی زی انگل بندپایان استان گیلان در سال های 1391-1389، 25 گونه لاروی متعلق به 20 جنس، 14 زیرخانواده، شش خانواده و چهار بالاخانواده از نمونه های خاک و از روی میزبان ها جداسازی و شناسایی شد که در بین آنها 12 گونه جدید برای دنیا، یک خانواده، شش گونه و پنج جنس به عنوان گزارش جدید برای ایران و چهار گونه گزارش جدید برای استان گیلان می باشند که به ترتیب با عل...
Population explosion is one of the problems of developing countries today. This topic has been evaluated from different standpoints. From a family point of view a variety of contraceptive devices and medications have been devised and used. At present, the available mean in men is only vasectomy (surgical and non-surgical) barrier method (condom). Since the available methods and medications do...
The energetic igniters through integrating B/Ti nano-multilayers on tantalum nitride (TaN) ignition bridge are designed and fabricated. The X-ray diffraction (XRD) and temperature coefficient of resistance (TCR) results show that nitrogen content has a great influence on the crystalline structure and TCR. TaN films under nitrogen ratio of 0.99 % exhibit a near-zero TCR value of approximately 10...
Objectives: Purpose of this study was to analyze the relationship and effects of family power structure, marital conflicts, and their components on mental health in male retirees of education in Alborz Province. Methods & Materials: In this research, a total of 341 male retirees of Alborz’s education department were selected by available sampling method. Research tools inc...
extract: most information about family assessment are gathered during home visits have many benefits. one of them is that information about structure and habits of families may be more real when you observe the house and around it to find supportive and obstacles for promotion of family health. in addition family members are often more comprehensive in their home and can better act for their ne...

جهت شناسایی و بررسی بیو سیستماتیکی فون جوندگان غرب استان گلستان از زمستان سال 1386 تا شهریور سال 1388 در اکوسیستم های مختلف استان اعم از جنگلی، استپی، کوهستانی و مناطق پست و هموار مرز ایران و ترکمنستان و مناطق شهری و روستایی با استفاده از تله زنده گیر مرده گیر نمونه برداری انجام شد و تعداد 134 نمونه از 13 گونه و پنج خانواده شامل: family hystricidae, hystrix indic family dipodidae, allactaga el...
nowadays, as a result of increased terrorist and bomb attacks throughout the globe in the vicinity of strategic buildings, designing these structures against impact loads, particularly the blast-related ones, has been taken into more consideration. the current procedure for designing the structure against an explosion is a design against the local failure of the current elements in the first st...
