First-Principles Plasma Simulations of Black-Hole Jet Launching.

Phys Rev Lett 2019 Jan;122(3):035101

Univ. Grenoble Alpes, CNRS, IPAG, 38000 Grenoble, France.

Black holes drive powerful plasma jets to relativistic velocities. This plasma should be collisionless, and self-consistently supplied by pair creation near the horizon. We present general-relativistic collisionless plasma simulations of Kerr-black-hole magnetospheres which begin from vacuum, inject e^{±} pairs based on local unscreened electric fields, and reach steady states with electromagnetically powered Blandford-Znajek jets and persistent current sheets.

Evaluation of Volatile Metabolites Emitted In-Vivo from Cold-Hardy Grapes during Ripening Using SPME and GC-MS: A Proof-of-Concept.

Molecules 2019 Feb 1;24(3). Epub 2019 Feb 1.

Interdepartmental Toxicology Graduate Program, Iowa State University, Ames, IA 50011, USA.

In this research, we propose a novel concept for a non-destructive evaluation of volatiles emitted from ripening grapes using solid-phase microextraction (SPME). This concept is novel to both the traditional vinifera grapes and the cold-hardy cultivars. Our sample models are cold-hardy varieties in the upper Midwest for which many of the basic multiyear grape flavor and wine style data is needed. Read More

[Preparation of samples for gas-chromatographic determination of fatty acids: direct transesterification of lipids of dry biological sample is preferred in comparison with the methods employing preliminary lipid extraction.]

Klin Lab Diagn 2018 ;63(3):141-147

National Medical Research Center of Cardiology, Moscow, Russian Federation, 121552.

Different methods of sample preparation and derivatization were compared from the point of view of product yield, speed and convenience of the technique used. Fatty acid determination in absolutely dry objects (biochemical preparations, food protein isolates, lyophilized microbial biomass) may be performed easily with the use of Folch method provided that 4-component system "chloroform/ methanol/water/acetic acid" was employed. Nevertheless, we ould not find any real advantages of classical Folch or Hara-Radin extraction method variants when compared to simple non-extraction technique (which consists in direct trans-esterification of dried biomaterial due to sequential sample treating with sodium methoxide and boron trifluoride methanolic solutions).

Membrane Processes for the Nuclear Fusion Fuel Cycle.

Membranes (Basel) 2018 Oct 12;8(4). Epub 2018 Oct 12.

Department DTE, ENEA, C.R. Casaccia, Via Anguillarese 301, S. Maria di Galeria, 00123 Rome, Italy.

This paper reviews the membrane processes for the nuclear fusion fuel cycle-namely, the treatment of the plasma exhaust gases and the extraction of tritium from the breeding blankets. With respect to the traditional processes, the application of membrane reactors to the fusion fuel cycle reduces the tritium inventory and processing time, thus increasing the safety and availability of the system. As an example, self-supported Pd-alloy membrane tubes have been studied for the separation of hydrogen and its isotopes from both gas- and liquid-tritiated streams through water-gas shift and isotopic swamping reactions.
