Constrained by resources and environment, reducing food losses is receiving increasing attention in China. This study uses data from 1,106 farmers to calculate rice harvest tests the impacts of mechanization farming scale. The results are: 1) loss rate averages 3.65%, it decreases as farm scale increases. 2) effects on vary with 3) Small- middle-scale are vulnerable production harvesting condit...

Culicoides biting midges (Diptera, Ceratopogonidae) are vectors of arboviruses that cause significant economic and welfare impact. Local-scale spread of Culicoides-borne arboviruses is largely determined by the between-farm movement of infected Culicoides.Study of the dispersal behaviour of Culicoides by capture-mark-recapture (CMR) is problematic due to the likelihood of mortality and changes ...

Abstract: The application of large scale energy storage makes wind farms more dispatchable, which lowers operating risks to the grid from interconnected large scale wind farms. In order to make full use of the flexibility and controllability of energy storage to improve the schedulability of wind farms, this paper presents a rolling and dispatching control strategy with a battery energy storage...

Although the movement of stable fly, Stomoxys calcitrans (L.), has been studied, its extent and significance has been uncertain. On a local scale (<13 km), fly movement occurs between host animals and resting sites to feed and mate, mainly at on-farm locations where herbivorous livestock regularly congregate. Small numbers emigrate from livestock congregation sites in search of other hosts and ...

The inflow an individual wind turbine experiences in a farm layout is strongly dependent on flow interaction effects with the turbines surrounding it. In addition to well-known wake flows, lateral and upstream effects, commonly described as blockage have also recently gained some attention. this work, measurements induction zone of neighboring are presented for different arrangements three seve...
