The aim of the present study was to differentiate two modalities of intrinsic time scales : i- the geometric or Euclidean modality, which is based on the constant speed of mass transport or of wave transmission in cylindrical ...

Volume estimates are particularly relevant in stands whose main production is wood. The objective of this study was to develop functions to estimate the total trade volume and with and without shell, with the help of ...

Abstract This study analyzes ontogenetic allometry in Aegla marginata Bond-Buckup & Buckup, 1994, a freshwater crustacean, in order to evaluate the growth pattern and the presence of sexual dimorphism, using a multivariate ...

Background Allometry, in general biology, measures the relative growth of a part in relation to the whole living organism. Using reported clinical data, we apply this concept for evaluating the probability of ventricular ...

There is no agreement among authors that study fish condition by the allometric method (K=W/Lb) with regard to the best procedure for b coefficient calculation. Some authors use a constant coefficient for all sub-samples ...
