Worldwide, the bird cherry-oat aphid, Rhopalosiphum padi, affects wheat, sorghum, and other grain crops, and conventional pesticides to control this aphid negatively affects the surrounding environment. Therefore, knowing the entomotoxicity of different chemical compounds against R. padi is an...

In this paper, we derive the time-dependent solution of the effective master equation for the reduced density matrix operator of a two-level atom driven by a coherent laser field and damped by a finite-bandwidth squeezed vacuum. The master equation has the standard form known from the broadband...

This paper proposes a cheap, maintenance-free generator suitable for maximum wind energy capture. It can be designed for low speed applications, where it could be rigidly coupled to a Sandia-17-m Darrieus wind turbine without the need of a gearbox. The generator is operated at varying shaft...

A wide range of institutional arrangements were practiced in the Community Based Fisheries Management project in phase-1 (1994-1999) and phase-2 (2001-2007). The project documents stated that there were three main fisheries management approaches; fisher-led, community-led and women-led, however...
