Sustainable development is a concept focused on preserving current resources for them to be available to future generations as well, while at the same time fulfilling current human needs and facilitating adequate levels of development. Nowadays, there are many possible applications of sustainability principles, such as in the fields of the economy, agriculture, environment, energy, transport, architecture, and production. Sustainable production of materials and goods aims at improving the processes which are less damaging to the environment, which conserve natural resources and use low levels of energy, possibly derived from sustainable sources. One of the intensive energy- and resource-consuming industries is the conventional production of technical ceramics. Although non-toxic, ceramic waste is generated during the machining of the green bodies and is typically landfilled. To improve the sustainability of technical ceramics production, methods of recycling ceramic waste need to be developed and applied.

In recent years, state policy has been aimed at accelerating Ukraine's integration into the European community, which provides for the improvement of social security. This should be facilitated by the active introduction of innovations. Market transformation of the economy requires solving a set of problems associated with the development of territorial communities. World experience shows that at present the main factor of economic growth is social dominants and the intellectual potential of the population. The article examines the theoretical, methodological and practical aspects of the development of social dominants as the core of the formation of territorial communities. With the help of these dominants, objective reasons are created and the possibilities for the formation of intellectual potential are determined. The main trends in the development of social dominants are analyzed, the assessment of the current state of the processes of social development on an innovative basis in the context of ensuring social cohesion of society is carried out. Particular attention is paid to the issues of using the resources of territorial communities. It is noted that a synergistic approach plays an important role, in particular when using human resources, determining their life trajectory, formed on a socio-innovative basis. The study revealed that social innovations become real if they are secured by investments, have a purposeful character, and acquire such forms of implementation as social projects and social reforms. It is emphasized that the specificity of innovation lies in the fact that it is not any purposeful change, but only one whose subject content is a practical innovation created as a response to human needs, after which it acquires maximum distribution until this need is completely saturated. Social innovations, as noted in the study, contribute to: the revival and enhancement of social and cultural values; ensuring social transformations of society; growth of labor potential; improving the quality of educational, medical, cultural and other services; and in general bring domestic social standards closer to the corresponding standards of developed European countries. Considerable attention is paid to the issues of enhancing socio-innovative activity. The authors note that the latter is achieved when it is based on solid knowledge. Therefore, the work pays great attention to the education system, including the provision of socio-innovative development of united territorial communities, which contributes to the formation of prerequisites for the innovative development of the country's economy and contributes to the development of a competitive economy as a whole. At the same time, the educational sphere itself must move to an innovative path of development, and this, in turn, needs to update the curricula, adapted to the realities of the modern period of the world and domestic economy. The article provides substantiated ways to improve the education system aimed at training competitive specialists. Also, the main directions of improving the image of knowledge, organizational and economic development of territorial communities have been developed.

Many wildlife species face imminent extinction because of human impacts, and therefore, a prevailing belief is that some wildlife species, particularly large carnivores and ungulates, cannot coexist with people at fine spatial scales (i.e., cannot regularly use the exact same point locations). This belief provides rationale for various conservation programs, such as resettling human communities outside protected areas. However, quantitative information on the capacity and mechanisms for wildlife to coexist with humans at fine spatial scales is scarce. Such information is vital, because the world is becoming increasingly crowded. Here, we provide empirical information about the capacity and mechanisms for tigers (a globally endangered species) to coexist with humans at fine spatial scales inside and outside Nepal’s Chitwan National Park, a flagship protected area for imperiled wildlife. Information obtained from field cameras in 2010 and 2011 indicated that human presence (i.e., people on foot and vehicles) was ubiquitous and abundant throughout the study site; however, tiger density was also high. Surprisingly, even at a fine spatial scale (i.e., camera locations), tigers spatially overlapped with people on foot and vehicles in both years. However, in both years, tigers offset their temporal activity patterns to be much less active during the day when human activity peaked. In addition to temporal displacement, tiger–human coexistence was likely enhanced by abundant tiger prey and low levels of tiger poaching. Incorporating fine-scale spatial and temporal activity patterns into conservation plans can help address a major global challenge—meeting human needs while sustaining wildlife.

Abstract This paper focuses on the field of enhanced oil recovery by means of a chemical flooding of oil deposit especially a surfactant flooding method. The main objective is the application of the aforementioned method at the Czech oil deposit Ždánice - Miocene which bears the crude oil of significant viscosity and gravity that does not allow conventional production methods to be used. We evaluated the performance of various surfactants in the laboratory environment by simulating oil recovery processes

Conventional production methods for high precision lens alignment typically rely on lens rotation. In the case of rotationally non-symmetric optics and mounts, this is problematic. Here, we report a new concept for alignment bonding without lens rotation, based on a high precision linear bearing as position reference and a hexapod actuator for lens manipulation. For the optical axis of two test lenses after bonding, <1 arcmin element tilt and <10 μm decentre was achieved. This is confirmed by an independent measurement. Our alignment device and process can be applied for any lens and mount geometry. This will be especially useful for high-end products with small size and for rotationally non-symmetric systems.

Nowadays in modern life, every technology and technique for comfortable life is available. People with low income, in other words, with low levels of economic power, can also have those facilities to stay warm in winter and stay cool in summer. Many years back when there were no advanced systems for human needs, passive strategies played a big role in peoples' lives. This paper concentrates on a small city in Iran that had used special strategies to solve peoples' environmental issues. The city is called Evaz, which is located in the Fars region of Iran with distance around 20 km from Gerash city and 370 km from south east of Shiraz. Evaz receives minimum rainfall, which is the reason why water is limited in this area and therefore, cisterns (water storage) had been used for many years that is studied in more detail in this paper. In summers, the climate is hot and dry, sometimes the external temperatures reaching around 46 °C during the day. Although the winters are typically cold and likewise dry, moderate climate is available in Evaz during autumn and spring. This study identifies some of the past strategies and describes them in detail with analysis for transformation and connections with the modern and traditional fundamentals. Furthermore, the study develops some solutions utilizing a combination of both modern and traditional techniques in design to suggest better and more effective ways to save energy, and at the same time to remain sustainable for the future.
