forest cover is one of the most effective factors in reducing flooding in northern iran, so that in recent years the destruction, land use changing and uncontrolled harvesting of forest areas, has greatly increased the number and magnitude of floods. so far, there have been few studies on forest hydrology in iran, particularly the northern hyrcanian forests. this study examines the impact of a ...

The main function of the photosynthetic process is to capture solar energy and to store it in the form of chemical 'fuels'. Increasingly, the photosynthetic machinery is being used for the production of biofuels such as bio-ethanol, biodiesel and bio-H2. Fuel production efficiency is directly dependent on the solar photon capture and conversion efficiency of the system. Green algae (e.g. Chlamy...

We revisit the entanglement harvesting protocol when two detectors are in causal contact. study role of field-mediated communication generating between interacting with a quantum field. provide quantitative estimator relative contribution versus genuine harvesting. For massless scalar fields flat spacetime, we show that can communicate via field, do not really harvest from and instead they get ...

The macromolecular pigment-protein complex has the merit of high efficiency for light-energy capture and transfer after long-term photosynthetic evolution. Here bio-dyes of A. platensis photosystem I (PSI) and spinach light-harvesting complex II (LHCII) are spontaneously sensitized on three types of designed TiO2 films, to assess the effects of pigment-protein complex on the performance of bio-...

Agricultural products have a main role in nonoil exports. Pistachio is one of the country's mostimportant export products. Thus, this study is aimed at evaluating and identifying pistachiomarketing in Rafsanjan which is carried out in 2011. This is applied study and its methodology iscorrelation. The statistical population was 120 agricultural extension experts of Rafsanjantownship were studied...

Rain-water-harvesting is one of the means by which agricultural production can be increased to meet the growing food demands in all regions. The study indentified the factor affecting rain-water-harvesting technology adoption for irrigation and farmers practice in water harvesting against drought in lowland woreda, Eastern Hararghe, Oromia Region. Both primary and secondary data were collected ...

Energy constrained systems such as sensor networks can increase their usable lifetimes by extracting energy from their environment. This is known as energy harvesting. Task scheduling at the single nodes should account for the properties of the regenerative energy source which fluctuates, capacity of the energy storage as well as deadlines of the time critical tasks. Designing efficient schedul...

Considering an energy harvesting sensor network, the overall probability of event loss is derived. Based on this result, a variety of harvesting resource allocation schemes (sizing the energy storages and the harvesting devices, under a total cost constraint) are provided. Their performances are verified and compared through simulations.
