Impact of seasons on industrial grounding resistance. [PDF]

Sci Rep
A properly designed and constructed ground electrode should perform well for many years. It must be periodically inspected to know its current technical condition. This obligation falls on the installation's owner. Depending on the function of the ground electrode in the entire installation, it may be a working, protective or lightning protection earth.

The Effect of Charcoal on the Improvement of Grounding Resistance as a Soil Treatment in Reducing Grounding Resistance

Journal of Renewable Energy, Electrical, and Computer Engineering, 2021
Current technological developments are very competitive with each other, both in electric power distribution systems or electronic equipment. Disturbances that occur are usually caused by short circuits and ground disturbances, or lightning strikes.

Common Ground for the Control of Multidrug-Resistant Salmonella in Ground Beef [PDF]

Clinical Infectious Diseases, 2006
A strategy to combat multidrug-resistant (MDR) Salmonella in ground beef is urgently needed. A national multi-disciplinary meeting reviewed the epidemiology of MDR Salmonella infection and contamination in humans, animals, and retail meat. In spite of a recent overall decrease in human MDR Salmonella isolates, certain types, such as Salmonella enterica

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

A TECHNIQUE OF MEASURING OF RESISTANCE OF A GROUNDING DEVICE

Electrical Engineering & Electromechanics, 2016
Introduction. Measurement of resistance of the grounding device (GD) by means of a three-electrode system. This requires not only the right choice of installation locations of measuring electrodes, but also the determination of the point of zero potential. Implementation of these requirements quite time-consuming, and in some cases impossible.

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

Molecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Profiling neoadjuvant therapy response in rectal cancer using meta‐analysis of publicly available transcriptomic RNA‐seq datasets

Molecular Oncology, EarlyView.
This study integrates publicly available transcriptomic datasets to identify molecular signatures associated with response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. By analyzing a combination of multiple cohorts with bioinformatics approaches, we reveal biological pathways and immune‐related features that may improve ...

PRECURSORY AND COSEISMIC CHANGES IN GROUND RESISTIVITY

Journal of Physics of the Earth, 1977
A resistivity variometer of unusually high sensitivity has been in operation at a crustal movement observatory about 60km south of Tokyo since 1968. The variometer records changes in ground resistivity caused by crustal strain in association with tidal loading. When a large earthquake occurs, the variometer often records a step-wise change.
