Tropical forests have long been known for being home to a huge biodiversity of plants, animals and microbes. Nevertheless, one of the most dangerous threats to the existence of tropical forests is fire. Fire in tropical forests does not only devastate the forest structure and biodiversity, but it also releases huge amounts of CO2 to the atmosphere. This study aims to observe land cover changes in...
In this paper semi-analytical forward-difference Monte Carlo simulation procedures are proposed for the determination of the lower order statistics and the Joint Probability Density Function (JPDF) of the stochastic response of geometrically nonlinear multi-degree-of-freedom structural systems subject to nonstationary Gaussian white noise excitation, as an alternative to conventional direct simulation...
The present work involves isolation of mango pectinesterase (PE) and polygalacturonase (PG), and investigating some of its characteristics, mainly with respect to heat-stability of the enzymes. Within a reaction time of 10 min, mango PE shows its maximal activity at pH 7 5 in a reaction mixture containing 1% citrus pectin and 0 1 or 0 2 m NaCl, at 55°C. This enzyme possesses a Z value of 18 ...
