to study the effect of different fertilizing systems on macro and micro nutrients uptake by annual medic (medicago scutellata cv. robinson) an experiment was conducted under dry farming and irrigated conditions at two research stations (sararood dryland agricultural research institute and soil fertility research station in mahidasht) during 2009 growing season. the experimental treatments consi...

Environmental sustainability needs to use resources efficiently and effectively from macro to micro level with a systematic approach. The dualistic relationship between ecosystem and human beings require considering ecological and social systems as well as economic factors known as the three-legged approach. Individuals and their perceptions are also important in this approach because of the ne...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...

Innovations in technologies, economic benefits, quality requirements and environmental concerns are changing the face of the existing power system. Centralized generating facilities are giving way to smaller, more distributed generation partially due to the loss of traditional economies of scale. The need of an intelligent grid, better known as Micro grid at the distribution end, has been recog...

Coral reefs, and the unique ecosystems they support, are facing severe threats by human activities and climate change. Our understanding of these threats is hampered by the lack of robust approaches for studying the micro-scale interactions between corals and their environment. Here we present an experimental platform, coral-on-a-chip, combining micropropagation and microfluidics to allow direc...

Recently, bubble-propelled micro/nanomotors have been considered as the cutting-edge micro/nano-sensing tools that use their unique features for fast detection of various hazardous environmental pollutants and biosensing.

Advances in design, materials and production technology for micro-optical components have led to strong growth in their use in today’s consumer products. In particular, micro-optical components produced by replication technologies such as UV embossing can now withstand the severe processing and environmental requirements of the consumer electronics industry, including lead-free IR reflow and th...

This paper describes the implementation of Multi Agent System (MAS) for advanced distributed energy management of a solar micro-grid. We consider a grid connected solar micro-grid with two solar Photo Voltaic (PV) systems, and each system contains a local consumer, a solar PV system and a battery. First we measure the load patterns and solar power generated in the two solar units. Then we use M...
