Biodegradation of polyvinyl chloride by Mucor s.p. and Penicillium s.p. isolated from soil

open access: yesRevista de Investigación, Desarrollo e Innovación, 2021
PVC is one of the most widely used plastics today and the one that produces the most waste. In recent years, microorganisms capable of degrading it have been reported, most of which come from environments in which PVC is accumulated. The aim of this work

Selection for an Optimum Growth Curve [PDF]

open access: yesBiometrics, 1968
Growth and development can be regarded as a stochastic process in continuous time. Moreover, in some situations of primary production, certain growth patterns may be more economical, or otherwise more desirable, than others. In this paper an attempt is made to develop techniques which could be used to exert some selection pressure for optimal growth ...

Body measurements from selective hunting: biometric features of red deer (Cervus elaphus) from Northern Apennine, Italy

open access: yesItalian Journal of Animal Science, 2016
Morphometric studies on European red deer (Cervus elaphus L.) living in sub-Mediterranean areas are rare. In this paper, we provide the first morphometric description of red deer from Apennine living in Prato Province, as well as a description of its ...

Age structure of amphibian populations with endemic chytridiomycosis, across climatic regions with markedly different infection risk

open access: yesEcology and Evolution, 2022
Threatening processes, such as disease, can drive major changes in population demographics of the host. Chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), has led to the decline of at least 500 amphibian species across ...

T-Growth Stochastic Model: Simulation and Inference via Metaheuristic Algorithms

open access: yesMathematics, 2021
The main objective of this work is to introduce a stochastic model associated with the one described by the T-growth curve, which is in turn a modification of the logistic curve. By conveniently reformulating the T curve, it may be obtained as a solution

Growth Curves in Lambs of Various Genotypes Created on the Basis of Improved Valachian and Tsigai Breeds

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
Changes in live weight or dimension for a period of time are explained by growth curves. The objective of this work was to evaluate the growth curves in lambs of 6 (1st experimental group) and/or 5 genotypes (2nd group) created on the basis of Improved ...
