Annotation: The article discusses the design of microgrids that use renewable energy sources and energy storage systems as a controlled local power system that operates in both grid-connected and island mode. The goal is to present an integrated approach that combines the choice of architectural design (AC/DC/hybrid), the selection of distributed energy resources (DER) and energy storage systems (ESS), and management requirements (power quality control, energy management system) within the framework of the IEEE 1547 and 2030 standards. Key methods for modeling and optimization, such as multicriteria and stochastic optimization, are described, as well as the main challenges to implementation, such as variability in generation, cyber resilience, and costs. Examples of successful projects demonstrate improvements in reliability, flexibility, and economic efficiency for local power systems.

Annotation: The article discusses the theoretical foundations of multi-user architecture and its practical implementation, using the DraftKings platform as an example. It analyzes three basic tenant isolation models and key patterns for organizing data storage in multi-user systems. It pays special attention to the problem of traffic isolation and financial transactions in conditions of high workload and regulatory restrictions. The article shows how the DraftKings architecture combines scalability, resilience, and compliance through the use of microservice approach, AWS infrastructure, proprietary testing, and risk management solutions. It highlights organizational and technical measures to reduce financial, regulatory, and reputational risks. Promising directions for the development of multi-user architectures are also noted.

Annotation: The article discusses environmental sustainability at the well testing stage, which is considered one of the most sensitive processes in the oil and gas industry. Based on an analysis of international standards, guidelines, and industry data, sources and types of impacts are summarized, including flaring and venting, water discharge, chemicals, and waste/spills. Practices for reducing these impacts are evaluated. It is shown that maximum effect can be achieved by combining in-line testing with multiphase flow meters, trapping and compression, integration into existing systems, product reinjection, and zero discharge of water. Highly efficient flare systems are also important, as well as transitioning to methane measurement and reporting (MRV) programs. Limitations are noted, and directions for future development are proposed.

Annotation: The article discusses the analysis of stress management techniques and prevention of professional burnout among chefs. It explores the psychological and physiological aspects of working in a kitchen, as well as the concept, stages, and symptoms of professional burnout. Additionally, it examines various methods and techniques for reducing stress levels. Special attention is given to practical recommendations for preventing burnout, such as organizational measures, self-regulation techniques, physical activity, group support, and the use of digital tools. The article emphasizes the importance of a comprehensive approach to stress management in order to maintain mental and emotional well-being, increase productivity, and enhance job satisfaction among employees. Future research directions include the development of innovative methods for preventing burnout, integrating digital technologies, and adapting international best practices to local contexts.
