Detergents including fatty acid salts act as surface-active agents and thus possibly damage the plasma membrane structures of aquatic organisms. Therefore, when excess, the house-used and industrial outflows of such detergents into aquatic environments may have considerable impacts on the ecosystem. In this study, we propose the use of green paramecia (Paramecium bursaria) for assessing the acu...

Almond [Prunus dulcis (Mill.) D.A. Webb] is one of the most important cultivated fruit trees in Iran. Late frost in spring is a key limiting factor for almond productivity given that almond trees flower early in the spring in comparison with other temperate fruit trees. To decrease frost injury in “Mamaei” cultivar, this study was carried out in factorial randomized complete block design (CRBD)...

abstract plant roots absorb water and minerals from soil solution. plant production is a function of root distribution and its activity in soil. by increasing root density in soil unit volume, roots absorb more water and minerals. this implies that knowledge of root development is an important factor for crop production. to determine the most suitable amount of water for the maximum development...

The reuse of mineral wastes is one of the most suitable solid wastes solutions. Throughout the world, the large of the granular aggregates used in constructions exploit natural mountain resources and rivers. Using mineral waste as a part of concrete, it can be helped to create a green environment and also contribute to sustainable development. Since the copper production process in the Sarchesh...

Software process improvement (SPI) aims to understand the software process as it is used within an organisation and thus drive the implementation of changes to that process to achieve speciWc goals such as increasing development speed, achieving higher product quality or reducing costs. Accordingly, SPI researchers must be equipped with the methodologies and tools to enable them to look within ...

The manufacturing industry is undergoing a major paradigm shift that is taking it from traditional manufacturing into a world of agile manufacturing. An agile corporation should be able to rationalize its manufacturing facilities and produce a large variety of products at lower cost in time. Designs of modular products and reconfigurable processes are crucial to agile manufacturing. Modular pro...

As software development cycles shorten, and software markets become more competitive, improved software development productivity continues to be a major concern in the software industry. Many believe that object-oriented technology provides a breakthrough solution to this problem, but there is little quantitative evidence to support this belief. Furthermore, most studies related to object-orien...

In the recent past, the Indian information technology industry has been able to grow at double-digit figures, thanks to the burgeoning demand for software services and products in the international market. Some of the Indian software companies have benefited from these changes, as they have been able to provide quality services at competitive prices to their offshore clients. However, these new...

In the rapidly developing shale gas industry, managing produced water is a major challenge for maintaining the profitability of shale gas extraction while protecting public health and the environment. We review the current state of practice for produced water management across the United States and discuss the interrelated regulatory, infrastructure, and economic drivers for produced water reus...

The interaction of chemical dispersants and suspended sediments with crude oil influences the fate and transport of oil spills in coastal waters. A wave tank study was conducted to investigate the effects of chemical dispersants and mineral fines on the dispersion of oil and the formation of oil-mineral-aggregates (OMAs) in natural seawater. Results of ultraviolet spectrofluorometry and gas chr...
