Annual, seasonal and spatial differences in the growth rate of Baltic cod larvae and early juveniles in relation to zooplankton biomass fluctuations in 2006-2014

open access: yesOceanological and Hydrobiological Studies, 2023
It is an acknowledged theory that a faster growth rate, determined by various environmental drivers, may boost the survival of larval and juvenile fish. In this study we examined the differences in the growth rate of larval and juvenile cod (age 2 – 136 ...

Assessment of inorganic nitrogen and phosphorus compounds removal efficiency from different types of wastewater using microalgae cultures

open access: yesOceanological and Hydrobiological Studies, 2022
The efficiency of ammonium nitrogen (N-NH4+) and phosphate (P-PO43−) removal from wastewater with different loads of these nutrients was evaluated using Chlamydomonas reinhardtii (Chlorophyta) and Oscillatoria neglecta (Cyanophyta/Cyanoprokaryota).

Acceptance of a Protein Concentrate from Alfalfa (Medicago sativa) by Yellow Perch (Perca flavescens) Fed a Formulated Diet

open access: yesFishes, 2021
The majority of plant proteins used in aquatic feeds are derived from seed meals, which may contain antinutritional factors. Protein concentrates from plant foliage have received less attention in fish feeding trials. Alfalfa protein concentrate (APC) is

How fast-growing bacteria robustly tune their ribosome concentration to approximate growth-rate maximization

open access: yesThe FEBS Journal, 2015
Maximization of growth rate is an important fitness strategy for bacteria. Bacteria can achieve this by expressing proteins at optimal concentrations, such that resources are not wasted.

Growth rate for beta-expansions

open access: yes, 2009
Let $\beta>1$ and let $m>\be$ be an integer. Each $x\in I_\be:=[0,\frac{m-1}{\beta-1}]$ can be represented in the form \[ x=\sum_{k=1}^\infty \epsilon_k\beta^{-k}, \] where $\epsilon_k\in\{0,1,...,m-1\}$ for all $k$ (a $\beta$-expansion of $x$).

Single-trait bayesian analysis of some growth traits in japanese quail

open access: yesBrazilian Journal of Poultry Science, 2014
The aim of this study was to estimate the heritability for some growth traits of Japanese quail through the estimation of variance components by Bayesian methodology. For this purpose, 340 progenies of 34 sires were used.
