Isolates of Pyricularia grisea from wheat (Triticum aestivum Lam.) and triticale (x Triticosecale Wittmack) spikes with blast symptoms were analyzed by classical (VCG) and molecular (RAPD) techniques. P. grisea mutants, unable to use sodium nitrate (nit) as nitrogen source, were obtained with potassium chlorate. For vegetative compatibility (VCG) tests, genetically complementary nit mutant pair...

background: the brown-banded cockroach, supella longipalpa , is not as common as the german cockroach in iran. this species seeks out areas that are very warm most of the time, and prefer warmer area than what german cock­roaches pre­fer. there is relationship between development of instars and diet of cockroaches. the aim of this study was to determine the effect of different diets on biology,...

This paper addresses the optimal design and planning of biomass-to-liquids (BTL) supply chains under economic and environmental criteria. The supply chain consists of multisite distributed-centralized BTL processing networks. The economic objective is measured by the total annualized cost, and the measure of environmental performance is the life cycle greenhouse gas emissions. A bi-criterion, m...

Due to increasing solid waste generation and their significant impacts on human health, environmental assessment of the management and disposal methods become more and more important. There are various disposal methods which are the combinations that originate from a wide range of solid waste management systems. In this study, municipal waste of Tehran (which totals to 7507.5 tons/day) is asses...

Lead and zinc production is one of the main predisposing factors of excessive greenhouse gases emissions, air pollution and water consumption. In this paper, the environmental problems of lead and zinc production in Calcimin plant are expressed and life cycle assessment of this plant is assessed. The data regarding the amount of induced global warming and pollution, acidification, and depletion...

The main purpose of this research is to evaluate the role of the company life cycle in providing an appropriate model in predicting the quality of discretionary accruals (Abnormal) using the Dickinson Cash Flow Model approach. The statistical population of the research consisted of 180 company observations that were divided into three stages of life cycle using Dickinson's model variables (2011...

The modal split model is one of the steps of the classical four-step travel demand planning. Predictive, descriptive, and prescriptive modal split models are essential to make a balance between travel demand and supply. To calibrate these models, it is necessary to detect and employ influential independent variables that are related to characteristics of travel modes, individual and family attr...

There are strong pedagogical arguments in favor of adopting computer-based assessment. The risks of technical failure can be managed and are offset by improvements in cost-effectiveness and quality assurance capability. Academic, administrative, and technical leads at an appropriately senior level within an institution need to be identified, so that they can act as effective advocates. All stak...

Smart products are hybrids that merge tangible products with mobile information technologies. This opens up unprecedented opportunities for product designers and marketing manager for implementing adaptive and situation-aware product interfaces that generate dynamic communication behavior with customers during the whole life-cycle of a product. The realization of this vision requires, beside ot...
