Teneral adults of Dinoderus porcellus were raised in the laboratory and exposed to various temperature regimes 10, 15 20, 30, 35 and 40 C respectively. Four dried yam species Dioscorea rotundata, Dioscorea alata, Dioscorea dumetorum and Dioscorea cayenensis were used, to determine the effect of temperature on oviposition and developmental stages of the insect. At 10C, there was no oviposition, ...

An indigenous wood rotting edible Lentinus kauffmanii isolated from Keeriparai forest of Western Ghats was studied for extracellular peroxidase production. Peroxidases are major extracellular lignolytic enzymes involved in lignocellulosic degradation. Physical factors such as pH, temperature and nutritional factors such as carbon, nitrogen sources and amino acids were standardized for the growt...

The recently developed Zurich Ice Nucleation Chamber (ZINC) was used to explore ice nucleation of size-selected mineral dust particles at temperatures between −20C and −55C. Four different mineral dust species have been tested: montmorillonite, kaolinite, illite and Arizona test dust (ATD). The selected particle diameters are 100 nm, 200 nm, 400 nm and 800 nm. Relative humidities with respect t...

A flow column has been innovatively used in the design of a new electrocoagulation reactor (ECR1) that will reduce the temperature of water being treated; where the flow columns work as a radiator for the water being treated. In order to investigate the performance of ECR1 and compare it to that of traditional reactors; 600 mL water samples with an initial temperature of 35C were pumped continu...

On the basis of degradation properties of Phanerochaete chroysosporium ME 446 found in white-rot fungi in respect of many organic compounds with toxic, mutagenic and carcinogenic characteristics, the physiological conditions effective for the degradation of heptachlor (1, 4, 5, 6, 7, 8, 8heptachloro-3a, 4, 7, 7a-tetrahydro-4, 7-methanoindene), an organic chlorine used in insecticides Phanerocha...
