SATELLITE STUDIES OF IONOSPHERIC MANIFESTATIONS OF ACOUSTIC-GRAVITY WAVES

Radio Physics and Radio Astronomy, 2014
The response of the ionospheric plasma on the propagation of acoustic-gravity waves (AGW) studied at altitudes of 250 − 350 km using the satellite Dynamics Explorer 2 measurements. Wave perturbations are analyzed according to simultaneously measured data

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Versatile vector tools for efficient protein screening across multiple expression systems

FEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Expressing the quantity of urinary analytes: a discussion of some issues arising from the monitoring of the menstrual cycle

Open Health, 2020
Practical domestic monitoring of the menstrual cycle requires measurements of urinary metabolites of reproductive hormones: oestrone glucuronide (E1G) and pregnanediol glucuronide (PdG). Data reported in the literature are expressed as (i) concentration,

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Design and Stress Analysis of a Combined Gravity Concentration and Leaching Drum for the Small‐Scale Gold Mining Industry in Ghana

The Journal of Engineering
Gold recovery for small‐scale mining is 50%, dropping to 20% when recovering fine gold of particle size less than 100 microns. Gravity concentration of gold prior to cyanidation significantly improves the recovery of very fine gold; therefore, this ...
