Criteria for Food Product Quality and Safety, Analysis of Factors Affecting the Effectiveness of a Food Safety Management System (FSMS)
type: item
description: ISO 22000:2018 specifies requirements for a Food Safety Management System (FSMS) for organizations in the food chain and integrates Codex and HACCP principles. This paper aims to systematize quality and safety criteria for food products using clear indicators and limit values, assess drivers that influence FSMS performance, and propose a composite FSMS Performance Index (FSMS-PI) based on key performance indicators (KPIs). The methodology was built on the Codex CXC 1-1969 (Rev. 2020) GHP/HACCP approach, ISO/TS 22002-1:2009 prerequisite programme (PRP) requirements, and limit values from relevant product standards. As illustrative objects, a criteria registry was developed for wheat flour and refined vegetable oil. For wheat flour, moisture content ≤15.5% (m/m) was selected as a core quality indicator. For refined vegetable oils, acid value ≤0.6 mg KOH/g, peroxide value (PV) ≤10 meq O₂/kg, and limits for Cu ≤0.1 mg/kg and Fe ≤1.5 mg/kg were set as baseline indicators

Development of the Structure and Operating Algorithm of a Micro Hydropower Plant with a Battery-Based Ballast Load
type: item
description: Micro hydropower plants (micro-HPPs) play a significant role in providing reliable and sustainable electricity to remote and rural areas. However, one of the main challenges in micro-HPP operation is maintaining stable voltage and frequency under variable load conditions. Traditional ballast load controllers dissipate excess energy as heat, leading to efficiency losses. This paper proposes an improved structural configuration and operating algorithm for a micro hydropower plant with a batterybased ballast load. The proposed system combines an electronic load controller with a battery energy storage system to absorb surplus power, enhance energy utilization, and stabilize operating parameters. The developed control algorithm ensures frequency regulation, optimal battery charging and discharging, and reliable operation of the asynchronous generator. Simulation-based analysis demonstrates that the proposed approach significantly improves overall system efficiency, power quality, and operational flexibility

A new technology for cleaning primary silk fibers from plant impurities in the preparation of raw materials for liquid paper
type: item
description: In the development of the rational technology of purification of prevodchik Uzbek-English ternary Los, it is necessary first of all to take into account the properties of interaction of foreign particles with fibers. The main mass of foreign mixtures of fibrous mass in the primary Los corresponds to fragments of branches or stems on the stalk and dry particles of mulberry tree. With silk fibers, the ilakish strength of the stem branches fluctuates between 1.56 and 2.76 sN teks intervals and mainly depends on the material of the STEM and the hem-budurdig of the surface. The friction coefficient on the surface of plant particles of silk thread is much higher than on the metal surface (except for the straw handle), and the roughness of these Horn surfaces will be higher

Analysis Of The Possibility Of Increasing The Efficiency Of The Ozone Electrosynthesis Process
type: item
description: The article provides information about the existing methods of ozone electrosynthesis and identifies their drawbacks. Based on the analysis of processes in the power supply circuit of ozone generators with sinusoidal and pulse voltage of high duty cycle, the possibility of reducing losses and increasing efficiency, increasing the yield of ozone, is substantiated. The distribution of the electric field intensity over the elements of a cylindrical ozone generator was analyzed when it was powered by a sinusoidal and periodic pulse voltage with a duty cycle of more than 5. It was found that it is possible to generate ozone without pre-cooling and drying the air, or cooling the dielectric barrier with running water

Disinfection Of Drinking Water From E.Coli And Tmc Using A Combined Ultraviolet And Ultrasound Device
type: item
description: In this study, a combined ultraviolet (UV) and ultrasound (US) device was proposed for rapid and stable disinfection of drinking water from Escherichia coli and total microbial count (TMC). Experiments were conducted in a flow-through reactor in the range of US (40 kHz; 2.27 W/cm²; 0.28 s) and UV (≈26.7 W/m²; lamp depth 3.6 cm; 4.58 s) parameters. It was observed that the cavitation effects of US weakened cell walls and enhanced the damaging effect of UV radiation at the DNA level; as a result, E. coli and TMC were sharply reduced, and the microbiological stability of water (the period before regrowth) was significantly extended compared to single methods. Maintaining the UV intensity around ~28–30 W/m² and placing the lamp close to the water surface increased the efficiency; in US, frequencies close to 40 kHz gave the best results. The combined mode provided high disinfection efficiency and energy efficiency with low contact time; this creates a convenient platform for practical implementation in small and medium-capacity drinking water systems.

Solving Problems in the Application and Development of Aviation Decoy Targets
type: item
description: Modern air combat environments are becoming increasingly hostile due to rapid advancements in radar, infrared (IR), and multi-spectral detection technologies. As a result, aviation decoy targets have become indispensable elements of aircraft survivability strategies. These devices, which include both towed and expendable variants, are designed to mislead enemy detection systems and intercept incoming threats. However, their operational performance is often limited by technical and tactical challenges, such as insufficient signal fidelity, limited adaptability to evolving threats, and integration issues with on-board electronic warfare (EW) systems. It presents a comprehensive examination of the challenges associated with the development and deployment of aviation decoy targets. A multi-layered research methodology involving system-level engineering analysis, digital modeling, and review of defense field data is employed to assess current decoy technologies. Key problems, such as reduced efficiency in harsh environmental conditions and vulnerability to advanced missile guidance systems, are identified and addressed. The findings suggest that significant improvements in decoy performance can be achieved through the use of adaptive emission algorithms, and modular hardware designs that allow better integration with the host aircraft’s EW suite. Case studies and simulation results support the proposed enhancements, demonstrating a measurable increase in aircraft survivability rates in complex threat environments. It concludes with a roadmap for future decoy development, emphasizing the need for collaborative international research, rapid prototyping, and real-time threat adaptation. These improvements are vital for maintaining air superiority and protecting high-value aerial assets in contested airspace.
