Green semilooper, Naranga aenescens Moore (Lepidoptera: Noctuidae) is a major pest in paddy fields of northern Iran. Since plant resistance to pests is a method with high efficacy and safety, a research was conducted to evaluate the resistance of 12 rice varieties (including, Tarom, Shafagh, Hybrid, Khazar, Poya, Fajr, Kados, Shiroodi, Sahel, Tabesh, Nemat and Neda) to N. aenescens on the basis...
Zn deficiency is one of the most important nutritional disorders after macro-nutrients in rice. There are considerable genotypic differences among rice genotypes in response to Zn deficiency. Determination of such differences and introduction of efficient genotypes could lead to significant reduction of fertilizer use for rice production. In this research, some of the most frequently cultivated...
background and objectives: rice plant requires abundant water during its growth cycle and usually faced with water deficit. drought stress alters the allocation assimilate , root and shoot growth during the vegetative period and also lower tillering, death tillers, lower plant height and flowering delay. the aim of this study was to screen different iranian genotypes and some lines from irri w...
In northern provinces of Iran high rates of incidence of glucose-6-phosphate dehydrogenase (G6PD) enzyme deficiency have been reported and most of these patients carry one of the three common G6PD gene mutations: Mediterranean, Chatham or Cosenza. The aim of this study was to investigate prevalence of each of these mutations among neonates in Mazandaran, a northern province of Iran. Four hundre...
Drought stress is considered as the most important limiting factor for growing of crops such as maize. Under low irrigation conditions, proper nutrition of plants can improve the effects of drought stress. This experiment was carried out in order to investigate the effect of nutrition management along with application of zeolite on agronomic traits of two hybrids of maize under deficit irrigati...
In this paper, an advanced analysis of a novel hybrid compression-absorption refrigeration system (HCARS) for natural gas dew point control unit in a gas refinery is presented. This unit separates the heavy hydrocarbon molecules in the natural gas, which is traditionally carried out by natural gas cooling in a compression refrigeration cycle (CRS). The power input required for the refrigeration...
Introduction: Achievement of rural development as a way to maintain national security and identity requires extra efforts regarding deprivation issue in backward regions and makes them receive their development rights. Economic development paves the way for creation of optimum and thriving life space. It is argued that physical isolation, potential economic and physical incapability, and rem...
This study investigates the interactive effects of processing parameters on quality milled rice using a one-step milling machine. Also, predictive models were generated response surface methodology. The moisture content (10–14 % dry basis), shaft speed rotation (600–900 rpm), and polishing time (1–3 min). evaluated (head yield, percentage broken rice, fine yield), cooking (optimum time, kernel ...
The emergence of new non-state actors in the post Cold War reality have dramatically changed security environment around the globe. Modern terrorism practiced by Al Qaeda and its associated movement (AQAM) has posed serious threat to critical information infrastructure given the trend of connecting control systems that run these infrastructures to the internet. Although AQAM have not been succe...
