Fundamental mechanics : newtonian mechanics for engineering
, 2023 This book is addressed at a first course in engineering mechanics. Newtonian mechanics is studied, a non-relativistic classical mechanics and, therefore, applied to objects that are neither extremely small nor excessively fast. The newtonian mechanics affects a good part of the world around us. It is the mechanics of the everyday world.

Geographic variation in walking activity in the red flour beetle Tribolium castaneum
Population Ecology, EarlyView.This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Population Ecology, EarlyView.We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,
