The in vitro and in vivo efficacy of three biocontrol agents, Trichoderma viride, Pseudomonas fluorescence, and Bacillus subtilis, were tested against Rhizoctonia solani (AG-4) infection compared to two conventional fungicides (Rizolex-T 50%wettable powder and Amistar 25%).Antifungal enzyme activity was assayed in the culture filtrate of the biocon
Some Design Considerations For High-power High-voltage Dc/dc Converter With Improved Power Density And Efficiency
This paper presents the findings of a R&D project Welding Chemical connected to the development of 50 kW auxiliary power supply for the high-voltage DC-fed commuter trains.The aim was to design a new-generation power converter utilizing high-voltage IGBT modules, which can outpace the predecessor (6.5 kV IGBT based twolevel half-bridge DC/DC conver

Introduction to the Biology and Control of Invasive Fishes and a Special Issue on This Topic
Across the globe, dozens of species of invasive fish are now found in fresh as well as marine waters, where they alter habitats, compete with native fish for food, and prey on native fishes, exerting both indirect and direct effects on ecosystems and economies.While efforts to understand and control these species are growing, most are still in thei
