The Muteh gold deposit (NE of Golpaygan) in the central part of intrusive-metamorphic belt of Sanandaj-Sirjan zone comprises NW-SE trending gold-quartz vein occurred in metamorphic complex. Gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. The sulfidation ...
مسئلة بحران آب در سال‌های اخیر و مصرف بیش از 70 درصد منابع آب شیرین در بخش کشاورزی آب لزوم اصلاح روش‌های آبیاری را، به‌منظور افزایش بهره‌وری آب، آشکار می‌سازد. در این مطالعه تأثیر اعمال پنج تیمار آبیاری کامل (FI)، کم‌آبیاری ناقص ریشه در دو سطح 75 درصد (PRD75) و 55 درصد (PRD55)، و کم‌آبیاری معمولی در دو سطح 75 درصد (DI75) و 55 درصد (DI55) بر عملکرد و اجزای عملکرد ذرت طی دو فصل زراعی 1389 و 1390 ...
This paper is a study of the use and possible flaws of the two basic cryptographic protocols (WEP, WPA) in Wi-Fi Networks. It is presenting some very easy to implement methods to gain malicious access to such networks by disclosing the network secret key, using Windows Operating Systems, like Win XP. It is also describing the shutter of the myth saying that the MAC Address filtering is a safe p...
modeling is one of the best tools for quantitative analyzing of biological systems that is helpful for understanding physiological basis of crops growth and development especially under limited water. in this study, a model was developed based on fao penman-monteith model to simulate soil water balance (swb) components and linked with wheat growth and development model, which was developed base...
