The character of Lake Kishkensor contamination in the area of underground nuclear explosions at the Semipalatinsk Test Site territory.

The timely identification of areas where man-made radionuclides migrate through water streams is highly important for the territory of the former Semipalatinsk Test Site since the aquatic environment is currently a source of secondary contamination of environment. This article presents research findings on radioactively contaminated Lake Kishkensor located at the Semipalatinsk Test Site territory. As a result of this research, a new locally contaminated spot was discovered in the vicinity of the "Balapan" test site.

Morphological and Molecular Analysis of Two Mycophagous Nematodes, and (Nematoda: Aphelenchoididae) from Florida Strawberry.

From 2016 to 2021, nematode surveys in Florida strawberry fields revealed several species of foliar nematodes ( spp.). was detected only in 2016 and 2017 on photosynthetic strawberry leaves/buds, but other not well characterized populations of sp.

Recombinase Polymerase Amplification assay for detection of the British root-knot nematode, .

Recombinase polymerase amplification (RPA) is an isothermal nucleic acid amplification technique that has been adopted for simple, robust, rapid, reliable diagnostics of nematodes. In this study, the real-time RPA assay and RPA assay combined with lateral flow dipsticks (LF-RPA) have been developed targeting the ITS rRNA gene of the British root-knot nematode, . The assay provided specific and rapid detection of this root-knot nematode species from crude nematode extracts without a DNA extraction step with a sensitivity of 0.

Tritium distribution in the 'water-soil-air' system in the Semipalatinsk Test Site.

This article presents research findings on 3H in abiotic environmental compartments, specifically, the 'water-soil-air' system. All of the research areas are located within the Semipalatinsk Test Site (STS): the perimeter of the 'Degelen' site, the riverside zone of the Shagan river and the 'background' area-the southeastern part of the STS (SEP). As research progressed, numerical values of 3H and its species were revealed in various environmental compartments.
