We report on experimental and theoretical studies of plasmon-induced effects in a hybrid nanostructure composed of light-harvesting complexes and metallic nanoparticles in the form of semicontinuous silver film. The results of continuous-wave and time-resolved spectroscopy indicate that absorption of the light-harvesting complexes is strongly enhanced upon coupling with the metallic film spaced...

In this paper we propose a new approach to coordinate multiple machines in the grain harvesting process, based on meta-constraint reasoning. This way we obtain more flexible plans that can be adapted at execution time. As an example scenario we focus on silage maize harvesting. We argue that more sophisticated flexible planning mechanisms are needed in order to obtain flexible plans that can be...

A simulation model, which depicts the harvesting operation of biomass supply chain, is presented in this paper. ExtendSim8 simulation software was used for the development of the model. There are a number of sequential operations, i.e. mowing, drying, baling, picking-up, loading, and transporting, for harvesting biomass until the final product arrives at bio-energy generation plant. Different s...

By means of Mawhin’s continuation theorem of coincidence degree theory, some sufficient conditions are obtained for the existence of at least two positive almost periodic solutions of harvesting predator-prey model with Holling III type functional response and time delays. An example and numerical simulations are employed to illustrate the main result of this paper. Key–Words: Almost periodicit...

the harvest date more influenced on postharvest quality during storage. in present study, fruits were harvested at four date base on total soluble solids content (5.5, 6.5, 7.5, and 8.5%) and then stored at 0.5 ºc and 80-90% rh, for 18 weeks. the samples were taken in 6th, 12th and 18th interval weeks and evaluated some parameters including weightless, losses, firmness, tss, ta, tss/ta, ascorbi...

this study aims to investigate the essential oils content of thymbr spicata l. in two times before flowering and full flowering in shirpenah area in ilam province. both samples were dried out in shade and without humidity. then 50 grams of each sample were powdered after obtaining the essential oils by hydro distillation using a clevenger apparatus for 2 hours. resulted oils were dried by anhyd...

Wireless Technology based smart sensor networks are becoming predominant from research point of view, since these smart sensors possess the exclusive features like mobility, ad-hoc nature of topology, heterogeneity of nodes, and deployment in huge scales along with the hardship of energy harvesting and routing. In this paper the concern is about the survey of emergence, modification, deployment...

where x 1 and x 2 are functions of two species, respectively; h and k are harvesting terms standing for the harvests (see [1, 2]). Because of the effect of changing environment such as the weather, season, and food, the number of species population periodically varies with the time. The rate of change usually is not a constant. Motivated by this, we consider the periodic nonautonomous populatio...

The harvest management studies on an improved lemongrass strain Jor Lab L(2), were carried out at the farm of regional research Laboratory Jorhat during 1991-94. The crop was harvested at 60,70,80,90 and 100 days interval. Maximum oil yield was obtained when harvested at 90 days interval. The citral content ranged from 88 to 90% irrespective of crop age and harvesting schedule. Harvesting time ...
