Vibrational Spectroscopy as a Sensitive Probe for the Chemistry of Intra-Phase Bacterial Growth

open access: yesSensors, 2020
Bacterial growth in batch cultures occurs in four phases (lag, exponential/log, stationary and death phase) that differ distinctly in number of different bacteria, biochemistry and physiology.

Optimizing Bioremediation: Elucidating Copper Accumulation Mechanisms of Acinetobacter sp. IrC2 Isolated From an Industrial Waste Treatment Center

open access: yesFrontiers in Microbiology, 2021
Acinetobacter sp. IrC2 is a copper-resistant bacterium isolated from an industrial waste treatment center in Rungkut, Surabaya. Copper-resistant bacteria are known to accumulate copper inside the cells as a mechanism to adapt to a copper-contaminated ...

Glucose concentrations in blood and tissue - a pilot study on variable time lag

open access: yesBiomedical Papers, 2015
Aim: The aim of this pilot study was to acquire insight into the parameters of glycaemic control, especially, (1) the time delay (lag phase) between plasma and tissue glucose concentrations in relation to rise and fall in glucose levels and (2) the rate ...

Qualitative Aspects in Dual-Phase-Lag Thermoelasticity [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2006
We consider the system of dual-phase-lag thermoelasticity proposed by Chandrasekharaiah and Tzou. First, we prove that the solutions of the problem are generated by a semigroup of quasi-contractions. Thus, the problem of the third order in time is well-posed. Then the exponential stability is investigated.

High-Throughput Rapid and Inexpensive Assay for Quantitative Determination of Low Cell-Density Yeast Cultures

open access: yesMicroorganisms, 2019
A procedure for microbial cell density determination with a high-throughput densitometric assay was developed to allow a precise quantification of both free and sessile cells, such as those of a biofilm, with a large range from low to high cell densities.

Thermoelastic responses of biological tissue under thermal shock based on three phase lag model

open access: yesCase Studies in Thermal Engineering, 2021
The paper dealt with the thermoelastic responses of biological tissues subjected to an abrupt input of temperature load in the context of generalized thermoelasticity with three phase lag times.

On the phase-lag heat equation with spatial dependent lags

open access: yesJournal of Mathematical Analysis and Applications, 2017
In this paper we investigate several qualitative properties of the solutions of the dual-phase-lag heat equation and the three-phase-lag heat equation. In the first case we assume that the parameter tTtT depends on the spatial position. We prove that when 2tT-tq2tT-tq is strictly positive the solutions are exponentially stable.

Climate and habitat configuration limit range expansion and patterns of dispersal in a non‐native lizard

open access: yesEcology and Evolution, 2021
Invasive species are one of the main causes of biodiversity loss worldwide. As introduced, populations increase in abundance and geographical range, so does the potential for negative impacts on native communities.

Population growth lags in introduced species

open access: yesEcology and Evolution, 2021
When introduced to new ecosystems, species' populations often grow immediately postrelease. Some introduced species, however, maintain a low population size for years or decades before sudden, rapid population growth is observed.
