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...

introduction: in this study in vitro maturation, resumption of meiosis and development of immature mouse oocytes in the presence of cysteamine was evaluated. meterial and methods: immature oocytes recovered from nmri mouse strain (4-6 weeks) were categorized in three experimental and one control group. the control included 345 immature oocytes which were matured in mem medium contain 5% fcs. in...

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...

studies of postmeiotic chromosomes have been impeded by the thick exine of immature pollen grains. chromosome staining of immature and adult pollen grains through conven-tional acetocarmine procedure is tedious and often leads to unsatisfactory results. an acetocarmine stain, used in conjugation with carnoy’s solution as fixative for 72 hrs or until the chlorophyll-containing tissues of spike b...
