Анализ и оценка неопределенности параметров, использованных при расчетах доз внутреннего облучения от трития [PDF]

, 2013
Assessment of committed effective dose and the uncertainty of its calculation for different variants of 3H intake: 1) homogeneous and chronic, 2) single, is considered by the example of internal tritium doses that workers had got.

Evaluation of a non‐radioactive rapid test for determination of serum progesterone in South American camelids

Veterinary Record, EarlyView.
Abstract Background Determination of the serum progesterone (P4) concentration is of high importance in reproductive medicine and may be applied for diagnosing pregnancy in South American camelids. P4 measurements in alpacas and llamas are usually performed using immunoassays, which are time consuming and require appropriate expertise of laboratory ...

Tritium Transfer and Concentratifon in the Ocean [PDF]

, 2004
Environmental transport models have been developed for evaluation of radiation doses from tritium released into the atmosphere. Recently, models contain not only inhalation and skin absorption as routes of tritium transfer from the atmosphere to humans ...

New Insights in the Electrochemical Stability of Various Solid Polymer Electrolytes/Layered Positive Metal‐Oxide Electrode Interfaces in Solid‐State Lithium‐Ion Battery

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
In this work, the electrochemical compatibility of a broad range of solid polymer electrolytes with two Ni‐rich nickel–manganese–cobalt cathodes (NMC622, NMC811) is investigated through a hybrid computational and experimental approach. The relative reactivity of NMC811 to NMC622 is demonstrated, as well as the role of Li cations in the electrolyte ...

Bacterial Cellulose Synthase Catalyzes the Formation of Chitin

ChemistrySelect, Volume 11, Issue 15, 20 April 2026.
Recombinant BcsA‐B from Rhodobacter sphaeroides is shown to cleave UDP‐GlcNAc (uridine diphosphate N‐acetylglucosamine), generating chitin with distinct β‐chitin Raman bands. These findings reveal that a cellulose synthase can process an alternative nucleotide sugar, providing biochemical evidence for the co‐synthesis of cellulose and chitin.

A Multi Tracer Approach Reveals Groundwater Residence Times and Dynamic Endmember Mixing in the Subterranean Estuary of a High Energy Beach

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Subterranean estuaries (STEs) under high‐energy conditions function as effective biogeochemical reactors, where waterbodies of varying physico‐chemical properties mix. Chemical reactions within the STE modulate the solute composition of groundwater discharging to the sea providing for example nutrients for plankton growth to coastal ecosystems.

Bioluminescence of the heterotrophic dinoflagellate Polykrikos kofoidii Chatton 1914 (Dinophyceae)

Journal of Phycology, Volume 62, Issue 2, Page 666-688, April 2026.
Abstract Heterotrophic dinoflagellates are important predators of phytoplankton, and many species produce bioluminescence, which is thought to serve as an antipredator function. The present study investigated the bioluminescence of the heterotrophic dinoflagellate Polykrikos kofoidii, an important predator of toxic and bloom‐forming dinoflagellates ...

Influence of plateau, slope, and valley on soil hydrology during the dry season in a Central Amazon old‐growth forest

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract Soil moisture regulates plant water supply and drought sensitivity in tropical forests, yet its vertical and topographic variation remains poorly characterized. We combined high‐frequency time‐domain reflectometry measurements from 5 to 100 cm across plateau, slope, and valley landforms at the Zona Florestal 2 research site north of Manaus ...
