Wireless Body Area Networks (WBANs) are an integral part of a sensor network, where nodes strategically placed in the human body to sense physiological signals and transmit them medical personnel via server for observations. Every node WBANs has general limitation energy efficiency, end-to-end delay, residual energy, etc. Also, high consumption is mainly due number hops covered during signal tr...

Source-sink relationships of field-grown plants of Coffea arabica L. cultivar 'Caturra' were manipulated to analyze the contribution of soluble sugars to sink feedback down-regulation of maximal leaf net CO2 assimilation rate (Amax). Total soluble sugar concentration (SSCm) and Amax were measured in the morning and afternoon on mature leaves of girdled branches bearing either high or low fruit ...

in this study the effects of source limitation on grain yield of twelve barley cultivars (‘aras’,‘jonub’,‘reihan’,‘zarjou’,‘sararoud’,‘sahra’,‘fajr30’,‘karoun’,‘gorgan’,‘makouei ’and ‘nosrat(’ under post anthesis water deficiency were studied. source limitation treatments were included that control, removing of awn, leaves below flag leaf, flag leaf and spike photosynthesis. all source limitati...

Mechanisms that allow plants to cope with a recurrent surplus of carbon in conditions of imbalance between source and sink activity has not received much attention. The response of sink growth and metabolism to the modulation of source activity was investigated using elevated CO(2) and elevated O(3) growth conditions in Erythronium americanum. Sink activity was monitored via slice and mitochond...

a study was conducted to evaluate the effects of moisture limitation on yield and dry matter distribution between shoot and root of triticale genotypes. this study was performed using a factorial experiment based on completely randomized design with four replications, in agricultural college of ferdowsi university of mashhad greenhouse during 2009. treatments were two available soil water inclu...

The ability to assimilate C and allocate non-structural carbohydrates (NSCs) to the most appropriate organs is crucial to maximize plant ecological or agronomic performance. Such C source and sink activities are differentially affected by environmental constraints. Under drought, plant growth is generally more sink than source limited as organ expansion or appearance rate is earlier and stronge...
