ABSTRACT Athelia rolfsii (Curzi) C.C. Tu & Kimbr. is the one of most damaging pathogens cultivated peanut, causing soilborne disease known regionally as white mold, stem rot, or southern blight. Because genetic base for peanut narrow, wild Arachis species may possess novel sources resistance. We evaluated 18 accessions representing 15 (batizocoi, benensis, cardenasii, correntina, cruziana, ...

The zooplankton biomass and distribution were studied during two oceanographic cruises in NE part of the Persian Gulf in autumn 2012 (November) and summer 2013 (August) with 300 μmmesh net. Zooplankton samples were analyzed for biomass content. Zooplankton biomass expressed as mg m-3 dry wt., was greatest during summer cruise (mean of 18.8 ± 4.6 mg m-3 dry wt.). The mean zooplankton bioma...

Background and purpose: Studies show that surface or subsurface water in some areas near to the pollutant sources, to an extent higher than the permisible potable limit are contaminated with cadmium. There are different reports about biological absorption of cadmium in high concentrations (present in industrial effluents) by bacterial biomass, but there is less report about removing of low co...

In large regions of the world, biomass is a very important source of energy. The global bioenergy market based on forest biomass is growing rapidly. About 92 % of the bioenergy in Sweden comes from forests. Biomass from forests is not homogenous. The locations, transport distances, and transport methods, can differ very much and the industries that need biomass as input prefer raw materials wit...
