Hydrogen fuel production from CO2/CH4 mixture using a novel type of an atmospheric pressure microwave (2.45 GHz) plasma source

Scientific Reports
We report the use of microwave plasma for the production of hydrogen-enriched gas by converting a mixture of CO₂ and CH₄. A novel type of compact and simple in design, waveguide-based, atmospheric pressure plasma source is used.

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

Molecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

Development of hydraulic fluid for heavy machinery [PDF]

Zastita Materijala, 2015
Various classifications and specifications for hydraulic fluids are prescribed, that were developed by standardization organizations, whose demands define quality levels and appointed methods for its testing. Hydraulic fluids quality demands are defined by constructors and manufacturers of hydraulic equipment (OEM - Original Equipment Manufacturer ...

Circumferential pressure distributions in a model labyrinth seal [PDF]

, 1982
A research program to isolate and study leakage flow through labyrinth glands was initiated. Circumferential pressure distributions were measured in the labyrinth glands with geometry appropriate to the high pressure labyrinths in large steam turbines ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

FEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Atmospheric pressure microwave (915 MHz) plasma for hydrogen production from steam reforming of ethanol

Scientific Reports
This work presents experimental results on the energy efficiency in hydrogen production using atmospheric microwave plasma (915 MHz) through steam reforming of ethanol. Ethanol was chosen as a liquid hydrogen carrier due to its high hydrogen atom content,

A Bramble-Pasciak-like method with applications in optimization [PDF]

, 2008
Saddle-point systems arise in many applications areas, in fact in any situation where an extremum principle arises with constraints. The Stokes problem describing slow viscous flow of an incompressible fluid is a classic example coming from partial ...

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...
