Problematic issues of operation and utilization of air turbine blades The gradual increase in the number of electricity producers predicts the further development of alternative energy. Renewable energy is an environmentally friendly, inexhaustible source of energy, which makes it possible to reduce the burden on the resource base and reduce overall resource consumption. In addition, the use of rene-wable energy sources contributes to the sustainable development of cities, which, thanks to solar, wind, biogas installations, can provide themselves with electricity, thereby reducing their costs and resource dependence. The population can independently produce electricity and control its distribution, while also minimizing losses during transmission over long distances. Wind energy is one of the promising areas in the field of renewable energy sources. The article examines the problematic issues of using wind energy and disposing of wind turbine blades, which is the main goal of the work. It is well known that certain conditions are required to generate electricity from wind turbines. As research has shown, the most promising places for the production of electrical energy are considered to be coastal sea areas, where powerful air currents are formed during the year. Research into the problem of disposal shows that this issue is very relevant and outweighs all the advantages of wind energy. The typical lifespan of wind turbine blades is about 20-25 years. Among the modern recycling methods, the following options are being considered to solve this problem ‒ using fiberglass as noise barriers, for example, on high-ways and pressing of blades, for example, into fibreboards for use as pallets in the construction industry, fencing and railway sleepers, etc. To achieve the goal, the authors of the article applied the methods of analytical review of scientist’s and specialist’s works of scientists and experts, systematic analysis of theoretical materials and practical recommendations in world practice regarding the operation and disposal of wind turbine elements. It was found that scientific analysis is mainly focused on researching the optimal and highest-quality disposal methods, which requires future, global research Ram air turbine ; Turbine ; Turbine blade ; Engineering ; Environmental science ; Aeronautics ; Business ; Marine engineering ; Mechanical engineering Material Properties and Applications ; Advanced Power Generation Technologies ; Technical Engine Diagnostics and Monitoring

Validation of L-Lactic Acid Production Using Companilactobacillus farciminis KUJ 25-S for Sustainable Bio-Polylactic Acid Manufacturing Companilactobacillus farciminis KUJ 25-S was isolated from fermented fish and identified using 16S rRNA gene sequencing with 30.0 g/L of L-LA (L-lactic acid), with 97% LA per sum of DL-LA. The characteristics of LA and its stereoisomers were confirmed using TLC, chiral-HPLC, and enzymatic techniques. Based on various conditions using liquid MRS broth (static condition, glucose 10%, NaCl 5%, 37 °C for 48 h), the highest growth and LA formation of the culture were at a low temperature (25 °C) and decreased at 37, 45, and 55 °C, respectively. The broth could grow and produce acid at an initial pH in the range 4–11, with a low initial pH of 4 promoting the highest LA formation. LA formation and growth were inversely proportional to the NaCl concentration in the 0.5–30% range. High glucose concentrations suppressed LA formation. The growth-promotion effect varied with glucose concentration (5–40%), with the optimum concentration for LA production being 20% glucose. On the other hand, if used in microoxic conditions, the absence of NaCl was more favorable to acidification than the addition of NaCl (5% NaCl). C. farciminis KUJ 25-S was proposed as a suitable method to produce L-LA based on using the appropriate line for further industrial use.

Artificial cell vesicle-mediated delivery of Catharanthus roseus (L.) G. Don-derived vinca alkaloids for enhanced antitumor efficacy Vinca alkaloids, a class of naturally derived antimitotic agents isolated from <i>Catharanthus roseus</i>, have long been established as potent chemotherapeutic drugs for the treatment of various malignancies. Despite their clinical efficacy, the therapeutic utility of vinca alkaloids, such as vincristine, vinblastine, and vinorelbine, is frequently constrained by systemic toxicity, poor bioavailability, and the emergence of multidrug resistance. In this study, we developed a universal strategy to construct cell membrane-derived vesicles for the encapsulation of vinca alkaloids, thereby enhancing their antitumor efficacy. These artificial cell vesicles were fabricated through the extraction and reconstitution of membranes from K562 cells. Following optimization of drug-loading efficiency, the resulting therapeutic vesicles, designated membrane-encapsulated vinca alkaloids (M@VAs), were thoroughly characterized to evaluate their drug delivery performance. An optimally formulated vincristine-loaded vesicle (M@vincristine) was subsequently used to assess its antitumor efficacy both <i>in vitro</i> and <i>in vivo</i>. M@vincristine induced a dose-dependent reduction in cell viability and demonstrated significantly greater tumor suppression than free vincristine. At the administered dose, M@vincristine not only promoted enhanced apoptosis but also modulated the expression of key apoptotic factors and effectively induced cell cycle arrest in the M phase. Following intravenous administration, M@vincristine demonstrated efficient tumor accumulation and superior anti-tumor efficacy compared to free vincristine. This artificial therapeutic platform not only addresses the major limitations associated with the clinical use of vinca alkaloids but also paves the way for the development of novel therapeutic agents with broad clinical applicability.

Shifting Focus to Quality: An Innovative Modeling Approach Includes Processing History for Rubber Part Quality Simulation An innovative modeling approach for the simulative description of the part quality of rubber materials, including the processing history, is presented in this paper. This modeling approach, the so-called average curing speed (ACS) model, is based on the degree of cure and the average curing speed instead of the conventionally considered temperature approach. Such approach neglects the processing history by calculating only the degree of cure. Thus, the correlation with part quality has to be performed either after the simulation or with the aid of other numerical analysis programs. Instead, by applying the ACS model, the key advantage is that the processing history is already taken into account during the filling and curing simulation, demanding a single calibration step with quality information to be able to calculate the part quality. For this purpose, parts were manufactured at mold temperatures ranging from 140 °C to 170 °C and degrees of cure from 24% to 99% via compression molding and subsequently the permanent deformation, i.e., the compression set (CS), of each part was analyzed. The CS results show that one and the same degree of cure; for example, 80%, which was defined on the basis of reaction isotherms, causes an almost twofold higher CS value for parts manufactured at 170 °C. Consequently, considerable deviations may occur when real part qualities are correlated with degrees of cure from simulations with common state-of-the-art kinetic models. By applying the ACS model, it was demonstrated that this challenge could be solved. Parts manufactured by compression molding exhibited the same quality as those simulated with the ACS model. Finally, this innovative modeling approach (fully implemented in the SIGMASOFT<sup>®</sup> v6.0 simulation routine) provides enormous potential for understanding local differences in the quality of rubber parts, being an ideal tool for optimizing rubber parts through simulation routines.

Development of a stabilization system composition for sauces and dressings The object of the study is the stability of a model emulsion with a stabilization system including liquid soy lecithin, xanthan gum, and esters of fatty acids and sucrose (E 473) under the influence of changes in the pH of the aqueous phase. A way to solve the problem of stabilizing emulsion systems in an acidic environment (pH from 4.0 to 5.5) is considered by rationalizing the composition of the stabilization system of sauces-dressings. It is determined that the stability of the emulsion system stabilized by soy lecithin and xanthan gum increases with increasing pH. At the same time, in the pH range of 3.5–5.0 it remains at a relatively low level (60–82 %), which requires improvement of the stabilization system for sauces-dressings. A rational range of E 473 concentration in the stabilization system for sauces-dressings is substantiated. It was found that the introduction of E 473 at a concentration of 0.3 % contributes to a significant increase in the stability of model emulsion samples under conditions of low pH values. An approximate dependence of the stability of the emulsion system on the concentration of E 473 and the pH of the aqueous phase is proposed, which allows predicting the effectiveness of the stabilization system under given conditions. A feature of the results obtained is that the use of E 473 provides a significant increase in the stability of the emulsion system, which is critically important for preserving the physicochemical properties of dressing sauces, which most often have an acidic environment. From a practical point of view, the development allows for effective stabilization of food emulsion systems in a wide pH range, reducing the risk of phase separation. An applied aspect of using the obtained scientific result is the possibility of modeling and developing new formulations of emulsion products, in particular dressing sauces, with improved structural and mechanical characteristics Composition (language) ; Food science ; Chemistry ; Art ; Literature Textile materials and evaluations ; Advanced Scientific Research Methods

Ecotoxicity and Biodegradation Behavior of a Bamboo-Based Plastic-Free Fibrous Composite The increasing environmental concerns associated with plastic waste have stimulated the development of fully bio-based and plastic-free materials for single-use applications. In this study, a bamboo-based fibrous composite composed entirely of plant-derived components was developed and evaluated with respect to its environmental behavior. Ecotoxicity was assessed using a standardized earthworm soil test (Eisenia fetida) conducted by an accredited third-party laboratory, while biodegradation behavior was examined under controlled aerobic composting conditions using a respirometric method. The ecotoxicological assessment showed no adverse effects on earthworm survival or body weight compared with the control compost. Biodegradation experiments performed in triplicate demonstrated that the composite achieved an average biodegradation rate of 86.4% after 360 days, with a reference material included to verify test validity. These results indicate that the bamboo-based fibrous composite exhibits low acute soil ecotoxicity and substantial biodegradability under controlled composting conditions. Within the scope of the present study, the findings provide experimental evidence regarding the environmental compatibility of fully bio-based bamboo composites and contribute to the evaluation of their biodegradation and ecotoxicological characteristics.

Portable Autonomous CO₂ Capture and Solid Carbon Production System for Aviation Applications Abstract - This paper presents a novel portable and autonomous system designed to capture carbon dioxide (CO2) directly from aircraft exhaust gases and convert it into solid carbon and oxygen through an electrochemical process. The system is compactly integrated near the aircraft’s engine wings, where it captures CO2 from exhaust emissions and channels it into a conversion module. Inside the module, the captured CO2 is reduced into solid carbon particles with a fine circular grain structure, while oxygen is simultaneously released into the atmosphere. The produced carbon is collected in an onboard storage tank equipped with an emergency ejection mechanism supported by a parachute for safe release in designated collection zones far from human settlements. This feature ensures aircraft safety while allowing post-flight recovery and reuse of the collected carbon. The system operates autonomously with minimal manual control, using the aircraft’s electrical power supply and sensor feedback for continuous emission processing. Although the process increases fuel consumption by approximately 20 percent due to the added power demand and aerodynamic load, it offers a promising approach to achieve in-flight carbon reduction and promote sustainable aviation. The recovered solid carbon can be repurposed in pigment, rubber, or composite material manufacturing, thereby supporting a circular economy, and providing dual environmental and industrial benefits.

OVERCOMING CHEMORESISTANCE IN CERVICAL CANCER: PHARMACOLOGICAL HURDLES AND NEW FRONTIERS Chemoresistance continues to be a significant obstacle to successful treatment of cervical cancer, especially in advanced and recurrent situations. Even with the effectiveness of cisplatin-based chemoradiotherapy as a standard option, numerous patients develop resistance that greatly diminishes therapeutic effectiveness and leads to unfavorable clinical results. The fundamental mechanisms of resistance are complex and include cellular, molecular, and microenvironmental alterations that enable tumor cells to endure cytotoxic attacks. Important pharmacological mechanisms involve the overexpression of efflux transporters like P-glycoprotein, improved DNA repair abilities, avoidance of apoptosis, and resistance induced by hypoxia within the tumor microenvironment. These adaptive responses allow cervical cancer cells to counteract the impacts of chemotherapy drugs. Tackling these mechanisms necessitates a comprehensive strategy that merges traditional chemotherapy with new approaches like targeted treatments, immune therapies, and advancements in drug delivery. New approaches like PARP inhibitors, immune checkpoint blockade, and nanoparticle-based drug delivery appear effective in reviving drug sensitivity and enhancing results. Furthermore, pharmacogenomic profiling provides a tailored method for choosing treatments that considers unique genetic differences.
