Two essentially isogenic strains of Escherichia coli K-12 were compared: D31 had chromosomally and D1-R1 episomally mediated resistance to ampicillin. The two strains had the same ability to form colonies on ampicillin plates, but in other tests they were quite different. In serial dilution tests as well as in exponentially growing cultures, D1-R1 was far more resistant to ampicillin than was D...

Measurement of 13C-labeled fatty acid oxidation is hindered by the need for acetate correction, measurement of the rate of CO2 production in a controlled environment, and frequent collection of breath samples. The use of deuterium-labeled fatty acids may overcome these limitations. Herein, d31-palmitate was validated against [1-13C]palmitate during exercise. Thirteen subjects with body mass ind...

The study has obtained composite systems containing porous polyvinylidene fluoride films and electroconducting polymers—polyaniline polypyrrole. Porous supports were prepared by melt extrusion. It was shown scanning electron atomic force microscopy that PVDF have a relief surface, higher surface roughness improves hydrophilicity of supports. layers conducting polymers on the formed oxidative po...

The culture growth and carotenogenic activity of two Greek Dunaliella salina strains (AthU-Al D30 AthU-Al D31) under stress conditions are investigated herein, with emphasis on β-carotene production as well lutein zeaxanthin. In particular, the were cultivated in “standard” (60 ‰ salinity 1.18 M NaNO3), (160 NaNO3) nitrogen deprivation 0 NaNO3). addition to strains, D. CCAP 19/18 strain, which ...

The front cover image illustrates the successful production of “heavy” deuterated linoleic acid. Deuterium was installed at beginning synthesis via hydrothermal deuteration readily available saturated fatty acids. acids were stitched together to ultimately afford requisite cis,cis-skipped diene Deuterated acid is required for labelled biologically relevant linoleoyl lipids, whereby facilitates ...

A two-dimensional (2D) material system with both piezoelectric and ferromagnetic (FM) orders, referred to as a 2D ferromagnetism (PFM), may open up unprecedented opportunities for intriguing physics. Inspired by experimentally synthesized Janus monolayer MoSSe from MoS2, in this work, the CrBr1.5I1.5 dynamic, mechanical, thermal stabilities is predicted, which constructed CrI3 replacing top I a...

Abstract The transverse piezoelectric coefficients d 31 of membranes is fundamental to the design, simulation, optimization, and applications devices using Aluminum Nitride (AlN). In this work, a method based on inverse effect proposed characterize . Based equation thin film vibration equation, central displacement Piezoelectric Micromachined Ultrasonic Transducers (PMUTs) linearly related DC v...

The reformulation of the median voter hypothesis and its testing proposed in Milanovic (2000) has been criticized from four different perspectives. The critiques are discussed and assessed. JEL classification: D31, E62
