The sharp rise in the development of vehicle industry in China not only promotes both the national economy development and the people living quality, but also aggravates both the national energy security and the environmental issues. Adopting alternative fuels instead of petroleum is commonly regarded as the utmost promising solution, however, which alternative fuel(s) is more suitable for China is still in the argument. The present paper compared the characteristics and performance of hydrogen gas and fossil-based fuels, and pointed that hydrogen gas is more suitable for China than fossil-based fuels.

Laws and regulations backing and governing public administration in subsoil use and protection in Ukraine is gradually gaining priority and importance given incoming energy security and resource self-sufficiency risks alerts for the State as one of the warrants for political and economic independence and guarantees for the people of Ukraine to enjoy and plenipotentiary implement its propitiatory rights set forth in the Constitution of Ukraine with regard to natural resources and benefits that constitute the genuine wealth of the nation. The article is written with the application of inductive reasoning and performance of various research methods, such as case studies, phenomenological study with some focus on nature and source of laws and administrative functions, grounded theory study; also a deep comparative analysis of domestic and overseas legal patterns is carried out. The article is devoted to the research of problems with regard to public administration in the field of subsoil use and protection in Ukraine. The author emphasizes that determination of public administration in the field of subsoil use and protection is a form of public managerial activities of public administration authorities (state authorities, local self-government bodies, self-governing public organizations with the respective competence). It is suggested that these activities are aimed at implementation of the policies in the field of geological exploration of mineral resources, mineral extraction, construction of underground and terrestrial facilities not related to the extraction of minerals, subsoil and environmental protection and they are based on the principles of interaction between subject and object of public administration, discretion, mutual responsibility, self-governance and decentralization when public services are provided. Also, the article presents many judicial practice of the European Court of Human Rights and Citizen, the Supreme Court in the field of public administration in the field of subsoil use and protection. In concluding notes amendments to Subsoil Code of Ukraine, methodology for calculating the initial selling price for the sale of special permit, selection procedures for open special permit tender bid winners and responsibility for subsoil use abandonment costs are suggested by the author.

Subject. The article reviews the way strategic threats to energy security influence the quality of people's life. Objectives. The study unfolds the theory of analyzing strategic threats to energy security by covering the matter of quality of people's life. Methods. To analyze the way strategic threats to energy security spread across cross-sectoral commodity and production chains and influences quality of people's living, I applied the factor analysis and general scientific methods of analysis and synthesis. Results. I suggest interpreting strategic threats to energy security as risks of people's quality of life due to a reduction in the volume of energy supply. I identified mechanisms reflecting how the fuel and energy complex and its development influence the quality of people's life. The article sets out the method to assess such quality-of-life risks arising from strategic threats to energy security. Conclusions and Relevance. In the current geopolitical situation, strategic threats to energy security cause long-standing adverse consequences for the quality of people's life. If strategic threats to energy security are further construed as risk of quality of people's life, this will facilitate the preparation and performance of a more effective governmental policy on energy, which will subsequently raise the economic well-being of people.

Much has been written about the link between HR and performance, however consensus has yet not been found concerning the understanding on how that relationship comes together. Empirically, no direct impact has been found and research has only suggested an indirect impact. Consequently, the Strategic HRM field is particularly interested on the understanding of the mediating variables that impact the organization performance. Besides the integrated and business strategy alignment of the HR function, it should be considered that it is the people (HR) of the organization and not their practices that determine the company´s competitive advantage. (Messersmith & Guthrie, 2010) argue that it is the impact of those practices that represent “the true resource and enable a sustainable advantage over industry rivals”. The objetive of this research proposal is to study the impact of strategic human resources practices on the organization performance through a case study methodology, supported by longitudinal data. Namely, the project aims to achieve a deeper understanding of the variables that affect the process stream during strategy implementation. How the HR practices impact on people? And why human resources are the most valuable asset? These core premises are in line with the most recent economic concerns about people productivity, employment policies and labor flexibility.

Among the alternative fuels existing for spark-ignition engines, ethanol is considered worldwide as an important renewable fuel when mixed with pure gasoline because of its favorable physicochemical properties. An in-depth and updated investigation on the issue of CO and HC engine out emissions related to use of ethanol/gasoline fuels in spark-ignition engines is therefore necessary. Starting from our experimental studies on engine out emissions of a last generation spark-ignition engine fueled with ethanol/gasoline fuels, the aim of this new investigation is to offer a complete literature review on the present state of ethanol combustion in last generation spark-ignition engines under real working conditions to clarify the possible change in CO and HC emissions. In the first section of this paper, a comparison between physicochemical properties of ethanol and gasoline is examined to assess the practicability of using ethanol as an alternative fuel for spark-ignition engines and to investigate the effect on engine out emissions and combustion efficiency. In the next section, this article focuses on the impact of ethanol/gasoline fuels on CO and HC formation. Many studies related to combustion characteristics and exhaust emissions in spark-ignition engines fueled with ethanol/gasoline fuels are thus discussed in detail. Most of these experimental investigations conclude that the addition of ethanol with gasoline fuel mixtures can really decrease the CO and HC exhaust emissions of last generation spark-ignition engines in several operating conditions.

Recently, reconfigurable drones have gained particular attention in the field of automation and flying robots. Unlike the conventional drones, they are characterized by a variable mechanical structure in flight, geometric adaptability, aerial reconfiguration, high number of actuators and control inputs, and variable mathematical model. In addition, they are exploited to flight in more cluttered environments, avoid collisions with obstacles, transport and grab objects, cross narrow and small spaces, decrease different aerial damages, optimize the consumed energy, and improve agility and maneuverability in flight. Moreover, these new drones are considered as a viable solution to provide them with specific and additional functionalities. They are a promising solution in the near future, since they allow increasing considerably the capabilities and performance of classical drones in terms of multi-functionalities, geometric adaptation, design characteristics, consumed energy, control, maneuverability, agility, efficiency, obstacles avoidance, and fault tolerant control. This paper explores very interesting and recent research works, which include the classification, the main characteristics, the various applications, and the existing designs of this particular class of drones. Besides, an in-depth review of the applied control strategies will be presented. The links of the videos displaying the results of these researches will be also shown. A comparative study between the different types of flying vehicles will be established. Finally, several new challenges and future directions for reconfigurable drones will be discussed.

As a country that is poor in petroleum yet rich in coal, it is significant for China to develop direct coal liquefaction (DCL) technology to relieve the pressure from petroleum shortages to guarantee national energy security. To improve the efficiency of the direct coal liquefaction process, scientists and researchers have made great contributions to studying and developing highly efficient hydrogen donor (H-donor) solvents. Nevertheless, the details of hydrogen donation and the transfer pathways of H-donor solvents are still unclear. The present work examined hydrogen donation and transfer pathways using a model H-donor solvent, tetralin, by density functional theory (DFT) calculation. The reaction condition and state of the solvent (gas or liquid) were considered, and the specific elementary reaction routes for hydrogen donation and transfer were calculated. In the DCL process, the dominant hydrogen donation mechanism was the concerted mechanism. The sequence of tetralin donating hydrogen atoms was α-H (C1–H) > δ-H (C4–H) > β-H (C2–H) > γ-H (C3–H). Compared to methyl, it was relatively hard for benzyl to obtain the first hydrogen atom from tetralin, while it was relatively easy to obtain the second and third hydrogen atoms from tetralin. Comparatively, it was easier for coal radicals to capture hydrogen atoms from the H-donor solvent than to obtain hydrogen atoms from hydrogen gas.

This study aims to discuss new and renewable energy policies as an effort to build national energy security. Research methods use legal research that searches from various perspectives. The implementation of analysis, using the method of regulatory and focus on energy, generally has many impacts. First, the policy on the use of new and renewable energy aims to prepare the carrying capacity of national energy security. Implementation this policy has not been fully implemented because there are still many obstacles faced. Second, the use of new energy and renewable energy as an effort to build national energy security in Indonesia is still not optimal. Even though Indonesia is blessed with abundant natural and energy resources in all its regions and the need for new and renewable energy as the future fate of energy security in the unitary state of the Republic of Indonesia for people's welfare as a step to reduce the increase in consumption of fossil-based energy.
