abstract this papare is resaults of analysing the data which reported from a harvesting project. the site for collecting data is buildings' roofs of azad islamic university of mashhad. a rain gauge and a small reservoir (capacity is 4 cubic meters) were set at this site. then the amount of precipitation and its runoff were measured during two years (from 1386, dey, 23 to 1388, tir, 3).the sampl...

Dielectric elastomer generators (DEGs) are attractive candidates for harvesting electrical energy from mechanical work since they comprise relatively few moving parts and large elastomer sheets can be mass produced. Successfully demonstrations of the DEG prototypes have been reported from a diverse of energy sources, including ocean waves, wind, flowing water and human movement. The energy dens...

the main objective of this descriptive-survey research was to investigate the application of waste management operations in apple production in abhar county. the statistical population of the study consisted of 12971 apple growers of the two districts of markazi and soltanieh out of which 100 people were selected as sample using cochran formula. stratified proportionate random sampling techniqu...

grain loss monitors are installed on combine harvester and make it possible to measure grain loss on different parts of the combine. the instrument permits the operator to adjust a proper ground speed to keep grain loss within an acceptable range. in this study a loss monitoring system was implemented to measure grain losses continuously on straw walker and sieves. two grain loss monitors (kee ...

401(K) LOSSES FROM THE ECONOMIC CRISIS: During 2008, major U.S. equity indexes were sharply negative, with the S&P 500 Index losing 37.0 percent for the year, which translated into corresponding losses in 401(k) retirement plan assets. But how individual 401(k) participants are affected by the crisis is largely determined by their account balance, age, and job tenure. IMPACT VARIES BY ACCOUNT B...

On the basis of conformal transformation, a general strategy is proposed to design plasmonic nanostructures capable of an efficient harvesting of light over a broadband spectrum. The surface plasmon modes propagate toward the singularity of these structures where the group velocity vanishes and energy accumulates. A considerable field enhancement and confinement is thus expected. Radiation loss...

The results of these studies showed that mechanical loader and combine harvester performance varied considerably depending on the type of machine, cane yield, and crop and field conditions. Instantaneous loading rates and mechanical harvesting pour rates varied between 60 and 100 tons per hour. Infield cane losses were significantly lower where the cane was manually cut and mechanically loaded ...
