rice is a main food for iranian people and has an important role in providing food security. regarding the population growth, increase of rice production and reduction of losses have special importance in prevention of rice import. rice losses in the harvest stage are the highest through the whole production period of this crop and hence the reduction of these losses is necessary. provision of ...

Recent interest in using forest residues and small-diameter material for biofuels is generating a renewed focus on harvesting impacts and forest sustainability. The rich legacy of research from whole-tree harvesting studies can be examined in light of this interest. Although this research largely focused on consequences for forest productivity, in particular carbon and nutrient pools, it also h...

Wireless Sensor node is one of the important technologies for the recent world applications like military, agriculture, health etc. But the major problem associated with these nodes is their battery dependence. The Battery Dependence for such nodes responds to the life time of the complete node.Failure of network due to node failure occurs when the battery completely depleted. To beware from su...

Fucoxanthin is a carotenoid that is mainly found in light-harvesting complexes from brown algae and diatoms. Due to the presence of a carbonyl group attached to polyene chains in polar environments, excitation produces an excited intra-molecular charge transfer. This intra-molecular charge transfer state plays a key role in the highly efficient (∼95%) energy-transfer from fucoxanthin to chlorop...

Energy harvesting is rapidly becoming a critical architectural component for CPS applications that use Wireless Sensor Networks (WSNs) technology. This paper presents an epoch-based approach for energy management in resourceconstrained WSNs that utilizing energy harvesting techniques. Each epoch represents a time period over which energy production can be reasonably predicted. We consider two e...

A technique of harvesting both internal mammary arteries thoracoscopically using three unilateral ports is described. Bilateral thoracoscopic internal mammary artery (IMA) harvesting was performed using a unilateral approach in 18 patients. The mean harvest time for harvesting was 52.3 +/- 17.5 min for the contralateral LIMA and 35.6 +/- 6.7 min for the ipsilateral RIMA. The mean free flow for ...

in order to study the effect of harvesting time on yield of rapeseed cultivars, this research work was carried out at paddy fields of rice research institute of iran in rasht andamol during 2005-2006 and 2006-2007 cropping seasons. the experiment was conducted in a split plot based on randomized complete block design with three replications. four rapeseed cultivars including hyola 308, hyola 40...

Energy harvesting techniques emerge as a potential solution for prolonging the lifetime of the energy-constrained mobile wireless devices. In this paper, we focus on radio frequency (RF) energy harvesting for multiuser multicarrier mobile wireless networks. The mobile users are capable of harvesting energy from the dedicated subcarriers over which they are communicating with the base station in...

manual citrus harvesting is commonly performing hard, expensive and time consuming. in this study, a factorial experiment with a completely randomized design in three replications was performed to find out the effect of frequency (three levels of 5, 7.5 and 10 hz), vibration time (three levels of 10, 15 and 20 seconds) on harvesting capacity and losses of thomson cultivar of orange. the results...
