Evaporative cooling is one of the techniques to lower the ambient air temperature according to the requirements. The technique includes the injection of moisture in the coming air, thus increasing its specific humidity. This technique can cool the air up to wet bulb temperature of the incoming air. In the recent past, the techniques are developed to lower the temperature of air without addition of moisture in the incoming air. These techniques demonstrate that the incoming air temperature can be approached near the dew point temperature of the incoming air. The present paper essentially focuses on the recent theoretical and experimental research of dew point evaporative coolers. Different flow configurations of heat exchange mediums, optimization of geometrical parameters, performance parameters (wet bulb and dew point effectiveness), energy efficiency ratio and energy saving potential are the key elements to study the prospects of dew point evaporative coolers over the conventional refrigeration systems operated by mechanical means. Dew point evaporative cooling technology is environmental friendly and has the potential in reducing the impact on earth due to global warming.

The diversified development of villagers’ livestock and poultry breeding models according to local conditions is one of the important paths for rural revitalization. Design different operation modes of livestock and poultry breeding and corresponding prevention and control of water pollution measures, establish a coordinated mechanism for villagers’ breeding and its water pollution prevention, and develop strategies for villagers’ breeding prevention and control of water pollution such as setting up harmless treatment station of dead livestock and poultry in order to achieve the goal of win-win cooperation between villagers’ interests, people’s needs and rural ecological environment.

The innovation in the energy sector involves the use of renewable resources and the transition to eco-energy, which requires a comparative analysis of the advantages and disadvantages for the economically sound choice when deciding on the energy strategy for each region. The use of alternative energy sources in Russia and the world is analyzed, which brings us to a conclusion that Russia is currently in an intermediate position in this area. Measures are proposed in orderd to strengthen the government support for Eco energy. It is held that the development of solar energy will play the largest role in the innovative development of the Republic of Tatarstan. The article is devoted to the problems of solar energy in Russia and Tatarstan respectively, as well as to the prospects for its development based on the proposed legislative, investment, financial and organizational solutions. The article provides a methodology for the comprehensive and effective adaptation of foreign experience in the field of alternative energy and a roadmap for the implementation.

The quality of the indoor environment, in terms of thermal, lighting, air and acoustic quality, grouped in the Indoor Environmental Quality (IEQ) concept, plays a key role in occupants’ wellbeing and satisfaction. Only in recent years IEQ has been investigated as a whole. Today, IEQ occupies the same place of energy efficiency in the design of buildings, especially those with high performance level as the Zero-Energy Buildings (ZEB). The research deals with an experimental campaign during the cooling season carried out in a ZEB laboratory that involved 100 participants aimed at evaluating the IEQ and the indoor environments (e.g. thermal and air quality). The test consists in a survey, during which each participant is required to answer a questionnaire about how he feels the indoor environment. The experimental campaign was completed with a monitoring activity aimed at detecting the main environmental variables that can affect the participants’ answers. Collected data were treated with regression techniques to highlight possible relationships between them. The results show how in a building with high levels of energy performances the air quality plays a key role on occupants’ evaluation.

Coastal zone is very vulnerable to the impacts of climate change. The increase of sea wave and sea level rise threaten coastal zone. The purpose of this study is to determine trends of significant wave height and sea level in the southern waters of the special region of Yogyakarta. The data used consists of daily significant wave height from 2010-2018, weekly absolute dynamics topography from 2005-2018 and daily surface wind from 2010-2018. Trends of significant wave height and sea level were analyzed by using linear regression. The results showed that significant wave height during the east season until the second transition season was higher than the west season and the first transition season. Vice versa, sea level during the east season until the second transition season was lower than the west season and the first transition season. Trends of significant wave height has increased of 0.63 cm/year, meanwhile sea level rise reached 0.82 cm/years.

In order to successfully achieve sustainable development objectives, modern enterprises have to establish a framework and implement appropriate managerial tools for the effective integration of sustainability into business operations. The paper aims to clarify the concept of sustainable development in the mine management context, highlight the main principles of sustainable mining and devise appropriate tools and mechanisms from a managerial viewpoint to implement the strategic sustainability priorities into business practice. Based on a literature review of research on sustainable mine management issues, the main dimensions of the sustainability concept are highlighted and the specific goals corresponding to each of the priority focus areas are identified in the paper. As a result of the study, the key organizational aspects and firm-level mechanisms that should be primarily taken into account from a management decision-making viewpoint to embed the strategic sustainability principles into business practices and corporate activities of mining operators are pointed out. From a practical perspective, the findings can be used by mining operators for defining strategic sustainability priorities and setting related corporate objectives, as well as devising guidelines for the effective implementation of the integrated sustainable mine management system.

It is evident that nowadays materials with phase or chemical transformations are significantly considered to be in surpassing demand in the society being used for accumulating thermal energy. Furthermore, this usage leads to the process of increasing accumulated thermal energy per unit mass concentration to be achieved in a much beneficial and reliable manner. In comparison to these materials, well-known and widely–used solid and liquid ones are mainly associated with productivity and efficiencylosses. One of the methods, having desirable attributes for substantial enhancement in the energy productivity of phase change materials is proved to be the addition of solid nanoparticles with a large coefficient of thermal conductivity. This work focuses on numerical and experimental investigation the influence of nanoparticles of various materials and sizes on the processes of thermal energy storage in paraffin. In particular, the proceeding data of the thermophysical properties of paraffin with nanoparticles as being found by the optical spectroscopy method. Moreover, due to comprehensive results in experimental and numerical studies, the heat accumulating capacity of the phase change materials, as well as the dynamics and profile of the melting boundary around cylindrical heat sources were reported to be determined. Besides, the comparison of heatstorage capacity for phase change materials with and without nanoparticles is managed.
