Disinfection Of Drinking Water From E.Coli And Tmc Using A Combined Ultraviolet And Ultrasound Device
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
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.

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.

A Comprehensive Analysis Of Mppt Techniques For Photovoltaic Systems Under Partial Shading Conditions
Maximizing power extraction from photovoltaic (PV) systems is crucial for improving efficiency, particularly under partial shading conditions (PSCs). The high cost and relatively low conversion efficiency of PV panels necessitate effective maximum power point tracking (MPPT) techniques to ensure operation at the maximum power point (MPP). This paper presents a comprehensive review of 11 MPPT methods reported in the literature, alongside recent advancements in hardware design methodologies. The MPPT techniques are classified into three categories—Classical, Intelligent, and Optimization-based—according to their underlying tracking algorithms. Under uniform irradiance, classical methods are generally preferred due to the presence of a single peak in the power–voltage (P–V) curve. However, under PSCs, the P–V curve exhibits multiple peaks, including one global MPP (GMPP) and several local MPPs (LMPPs). As a result, intelligent and optimization-based techniques have emerged to accurately identify the GMPP among all local peaks. Each MPPT technique is critically analyzed in terms of sensor requirements, hardware implementation complexity, performance under PSCs, cost, tracking speed, and tracking efficiency. This study consolidates recent advancements and highlights potential research directions to support further development in the field.

Currently, The Problems Of the Process Of Moistening Raw Cotton and Cotton Fiber
The moistening of raw cotton and cotton fiber is a critical stage in the textile production process, significantly influencing the quality of the final product. However, achieving optimal moisture content presents numerous challenges. One of the primary problems is the uneven distribution of moisture during processing, which can lead to variations in fiber strength and quality. The inappropriate application of water or humidification methods often causes fiber shrinkage, reduced durability, and increased contamination. Furthermore, the control of temperature and humidity plays a vital role in preventing over-drying or excessive moisture retention, both of which can negatively affect the spinning and handling properties of cotton fibers. Technological limitations, coupled with the complexity of monitoring moisture levels accurately, result in inefficiencies in the cotton processing industry. Research has also shown that improper moisture regulation can lead to decreased efficiency in machinery, increased energy consumption, and a higher likelihood of fiber damage during transportation and storage. Therefore, addressing these issues requires advancements in moisture control technologies and the development of standardized procedures to ensure consistent and high-quality cotton fiber production
