We present a simple model to evaluate the sharpness of the band edges for tunnel field-effect transistors by comparing the subthreshold swing and the conductance in the negative differential resistance region. This model is evaluated using experimental data from InAs/InGaAsSb/GaSb nanowire tunnel-field effect transistors with the ability to reach a subthreshold swing well below the thermal limit.
Background and Objective: Climate change poses a threat for agriculture and development in Rwanda. The agricultural sector in Rwanda is the engine of economic growth and modernization. This study examines the role of community based organizations (CBOs) in transferring climate change information to farmers’ communities in Rwanda. Materials and Methods: Three districts (Kirehe, Rwamagana and Ngoma)
Fox hunting was, in the years preceding the First World War, a crucial part of rural English life, and a means of promoting a variety of ideologies associated with class, gender and rule. At this time, the anti-hunt movement was virtually nonexistent. Though the First World War was not a catalyst for a mass movement, it did occasion change, both materially in the hunting community and in societal
Svensk sammanfattningKraftiga förluster av pollinerare är oroande och det har talats om risken för att en pollineringskris ska uppstå, med konsekvenser för både människor och miljö. De flesta blommande växter och tre av fyra odlade grödor är nämligen insektspollinerade (Box 1). Minskningarna hänger ihop med det moderna jordbrukets utveckling. Många gamla hagmarker och ängsmarker där bin och fjärilAgricultural intensification and associated loss of semi-natural grasslands, has resulted in reduced landscape heterogeneity. A concomitant loss of forage and nest sites for pollinating insects has driven declines across several pollinator taxa. Because 75% of the cultivated crops and more than 85% of the flowering plant species are insectpollinated, concerns have been raised that the pollinator d
The present meta-analysis investigated the relations between creative self-efficacy (CSE) and creativity measures and hypothesized that self-assessed questionnaires would have a different relation to self-efficacy beliefs compared to other creativity tests. The meta-analysis synthesized 60 effect sizes from 41 papers (overall N = 17226). Taken as a whole, the relation between CSE and creativity meThis meta-analysis investigated the relations between creative self-efficacy (CSE) and creativity measures and hypothesized that self-assessed questionnaires would have a different relation to self-efficacy beliefs compared to other creativity tests.
