Increasing Beef Production in the Northern Region of the Republic of Kazakhstan Using the Genetic Resources of Aberdeen Angus Cattle of Different Genotypes.

This article presents the findings of a scientific study investigating the efficacy of various assessment techniques used to evaluate the adaptability and productive qualities of Aberdeen Angus cattle on three prominent farms in the northern region of the Republic of Kazakhstan. A comprehensive analysis of the haematological and biochemical parameters of experimental groups of cattle with different genotypes (American, Canadian, and Estonian selection) was conducted. The studies revealed notable variability in haematological and biochemical indicators, contingent on the origin.

Fracture Dynamics in Silicon Anode Solid-State Batteries.

Solid-state batteries (SSBs) with silicon anodes could enable improved safety and energy density compared to lithium-ion batteries. However, degradation arising from the massive volumetric changes of silicon anodes during cycling is not well understood in solid-state systems. Here, we use X-ray computed microtomography to reveal micro- to macro-scale chemo-mechanical degradation processes of silicon anodes in SSBs.

Insights into enhanced learning through virtual reality.

Introduction: This study investigates the impact of Immersive Virtual Reality (VR) on learning outcomes in radiography training using Virtual Medical Coaching's X-Ray Pro VR software. VR offers immersive experiential learning that may enhance academic performance and professional preparedness.

Methods: The study involved 130 students from two consecutive cohorts: one using traditional training methods and the other using VR software.

Equine Sarcocystosis in the Northern Region of the Republic of Kazakhstan.

Background: A total of 396 samples were taken from the hearts, oesophagi, and diaphragms of 132 horses slaughtered at slaughterhouses in 2023 for subsequent examination.

Methods: The histological method revealed pathomorphological changes in the muscle tissue. The molecular method identified the pathogen species.

Laminography as a tool for imaging large-size samples with high resolution.

Despite the increased brilliance of the new generation synchrotron sources, there is still a challenge with high-resolution scanning of very thick and absorbing samples, such as a whole mouse brain stained with heavy elements, and, extending further, brains of primates. Samples are typically cut into smaller parts, to ensure a sufficient X-ray transmission, and scanned separately. Compared with the standard tomography setup where the sample would be cut into many pillars, the laminographic geometry operates with slab-shaped sections significantly reducing the number of sample parts to be prepared, the cutting damage and data stitching problems.
