In this work we attempt to show in a clear and simple manner the fundamental ideas of the Renormalization Theory. With that intention we use two well-known problems of the Physic and Engeneering undergraduate students, the calculation of the electrostatic and vector potential of a infinite line charge density and current, respectively. We still employ different regularization methods (cut-off, ...

Abutilon indicum (Linn.) a Malvaceae member is used in our traditional system of medicine for healing various diseases. It is used in the treatment of piles, uterine discharge, and febrifuge and in cases of pulmonary tuberculosis. In the present investigation an attempt was made to study its pharmacognostical features, including macroscopic, microscopic features, physic-chemical parameters, ste...

Background and Objectives: Rheological characteristics of dough are important for achieving useful information about raw-material quality, dough behavior during mechanical handling, and textural characteristics of products. Our purpose in the present research is to apply soft computation tools for predicting the rheological properties of dough out of simple measurable factors. Materials and Me...

Spatial distribution studies in pest management identify the locations where pest attacks on crops are most severe, enabling us to understand and predict the movement of such pests. Studies on the spatial distribution of two mite species, however, are rather scarce. The mites Polyphagotarsonemus latus and Tetranychus bastosi are the major pests affecting physic nut plantations (Jatropha curcas)...
