Mexican Creole chickens: effect of data collection periods on goodness-of-fit and parameter precision of growth models

open access: yesPoultry Science, 2022
: The objective of this study was to estimate the good-of-fitness and precision of parameters of the Gompertz-Laird, Logistic, Richards, and Von Bertalanffy growth models, using different data collection periods (DCP).

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

Laboratory Investigations of Mold Growth on Transverse and Longitudinal Wood Surfaces

open access: yesApplied Sciences, 2022
The possible influence of anatomical sections of wood on mold growth was investigated by means of a laboratory experiment. The selected fungi, Aspergillus sp., Penicillium sp., and Alternaria sp.

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 ...

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 ...

Explicit L-functions and a Brauer-Siegel theorem for Hessian elliptic curves [PDF]

open access: yes, 2017
For a finite field $\mathbb{F}_q$ of characteristic $p\geq 5$ and $K=\mathbb{F}_q(t)$, we consider the family of elliptic curves $E_d$ over $K$ given by $y^2+xy - t^dy=x^3$ for all integers $d$ coprime to $q$. We provide an explicit expression for the $L$

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 ...

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

Radiation from Isolated Spectral Lines with Combined Doppler and Lorentz Broadening [PDF]

open access: yes, 1953
Methods for the calculation of spectral absorption coefficients for combined Doppler and Lorentz broadening are summarized. The “curves of growth” have been extended to cover the ranges of parameters which arise in spectroscopic studies on ...

Nonlinear Mixed-Effect Models to Describe Growth Curves of Pepper Fruits in Eight Cultivars Including Group Effects

open access: yesAgronomy, 2023
Evaluating the behavior of fruit width and length characters throughout the pepper crop cycle is essential for researchers in decision-making aimed at developing appropriate management techniques and harvesting fruits at proper growth stages.
