SummarySubject and purpose of work: The subject of this analysis and evaluation is the use of renewable energy sources in Poland, particularly in the Lubelskie Voivodeship, as a peripheral region. The purpose of this paper is to identify the role and evaluate the scale and effects of using renewable energy sources (RES), as well as the availability and absorption of financial resources for RES promotion.Materials and methods: The data were obtained from the Office of the Ruda-Huta Commune, the Regional Operational Programme Department of the Marshal Office of the Lubelskie Voivodeship in Lublin and the Department of European Funds of the Ministry of Energy, as well as Statistics Poland (GUS) and the literature on the subject.Results: In Poland the proportion of energy from renewable sources to the total primary energy generated increased in 2012-2018 from 11.73% to 14.46%. A new phenomenon, which has been highly significant for the development of this sector, is the use of innovative, small-scale technologies of energy generation from renewable sources, which created the foundations for the growth of a citizens’ energy sector, based on the initiative of the citizens and their communities. The use of RES contributes to reduced expenditures on the purchase of energy carriers and constitutes an effective method of implementing plans for developing a low-carbon economy and reducing low-stack emissions.Conclusions: The continuing disparities between the regions point to the need for active structural intervention to maintain economic, social and territorial cohesion, particularly in areas which are considered peripheral and have a very low GDP per capita. One of the preferred directions should be to support the use of RES.

In recent years the subject of energy planning has come to occupy a role of growing importance, both in relation to the escalating costs, scarcity and impact of energy procurement and consumption and in relation to the increasingly broad future prospects generated by the development of technologies for the exploitation of renewable sources. Within this framework, the development and use of the latter frequently appears to be without benchmarks for integration into the broader picture of territorial planning, and hence of coordination with other human activities and territorial resources. With this in mind, this book aims to compose the elements of a perspective in which energy planning is seen not as an ulterior and separate form of planning, but as an activity integrated within the more general instruments for the government of the territory, and more specifically one that employs the resources of the territory in a sustainable manner also with a view to endogenous local development.

One of the basic aspects of sustainable development strategy involves investments in green technologies, including energy production from renewable sources. Biomass, special organic waste which belongs to “green sources” of energy can be used in the methane fermentation process of biogas production to generate heat and electricity.Biogas power plants have functioned in the Polish energy industry for many years now. On the basis of the data available from Central Statistical Office, in 2014 the ratio of biogas accounted for 7.6% of the structure of primary energy derived from renewable sources in the EU and 2.6% in Poland. An important consideration related to the production of biogas is associated with the applicability of waste resources derived from agricultural production and from the food industry, including pig slurry, slaughterhouse waste, brewing and distilling dregs as well as others. The operation of biogas plants provides considerable benefits to the environment, resulting from the controlled fermentation process and its application in the production of useful energy, as it can provide reduction of the emission of methane and other greenhouse gases. The aspects including the reduction of the volume of waste, environmental protection, fulfillment of the EU obligations and local energy security, form the reasons why communes in Poland should focus their attention on the use of biogas.This paper presents the results of SWOT analysis of biogas production in the context of sustainable development. The assessment of the aspects (strengths, weaknesses, opportunities and threats) and the intensity of their impact were undertaken on the basis of a point scale developed by the authors. The analysis shows that the process demonstrates a number of strengths, which can promote the implementation of positive changes in the environmental and social aspects undertaken on a local scale.

We presented the results of analysis of characteristics of osteosynthesis of femur model with improved metal structure. We carried out the analysis of the literature and a patent search on the subject of the study, created a layout of this design, a prototype and tested strength characteristics using a breaking machine. We carried out the work on a bovine femur preparation, performed taking into account the maximum correspondence of the studied human femur segment. We carried out load samples for fabricated steel structures, as well as for prototypes of this design in the form of samples for shear, angular displacement and rupture, while for each sample, performed 2 versions of the location of the steel structure relative to the fracture – perpendicular to the fracture line (angle 90º), as well as with a deviation in the range of 30º (75º–105º). We detected a statistically significant increase in the load values for the new advanced steel structure at a right angle of 41 % and a variation of 56 % during the analysis of the sample for rupture. Thus, when comparing the values of the load samples of the prototype and the manufactured metal structure, we revealed an increase in the indicators of the burst sample for the new metal structure which indicates the justification of its use in clinical practice.

In the conditions of Uzbekistan, to increase the ranгe of production of natural and environmentally friendly wine products from fruit and berry raw materials, as well as to effectively use raw materials, the production of export-oriented natural younг wines is a very urгent problem, based on the fact that the purpose of our study was to improve the existinг technoloгies in the Republic. for the production of fruit and berry wines on a biocatalytic basis, by stimulatinг zymoгenic enzymes of raw materials and yeast exohydrolases. To achieve this гoal, berries such as red cherries, strawberries, raspberries, currants and shotut were used as objects. The subject of the study was the creation of a fundamentally new technoloгy for the production of natural and export-oriented wine products from fruit and berry raw materials, as well as the research method was the determination of physicochemical, biochemical, technical and technoloгical parameters and the analysis of orгanoleptic indicators of objects by standard methods. The study showed that under an unfavorable environment, the cells of fruit and berry raw materials fall into stress as a result, under the influence of zymogenic exo- and endo enzymes of plant cells, it degrades biopolymers such as pectin and protein, which are the main components of the cytoplasmic membrane of cells, and a fundamentally new technology was developed, which allows to separate the fermentation process from the extraction of valuable components of raw materials due to the enhancement of the secondary metabolism of yeast associated with "high synthesis" in a controlled fermentation process. Moreover, in the process of carbon dioxide maceration, the yield of high-quality juice from 1 ton of raw material was increased by 10-12%, and the yield of wine material due to a decrease in yeast increased by 3.5%, due to the continuity of the process by 0.7% and the biosynthesis of ethyl alcohol was increased by 1 ÷ 1.5% vol. Natural wine products have been developed that have a pleasant harmonious taste and aroma due to their organoleptic properties.

Inventions related to pre-harvest and post-harvest technologies have revolutionized agriculture. There is a significant growth of intellectual property rights (IPR) in agriculture across the globe. The predominant forms of IP relevant to agriculture sector are patents and designs. Patents are given to inventions that qualify patent eligibility, patentability criteria and disclosure norms. In the area of agriculture, patents provide a great opportunity for improving agricultural processes and products. Understanding the requirements of an invention under the Indian Patents Act, 1970 is necessary to know what can be patentable in India. The criteria of novelty, non-obviousness and industrial application and disclosure norms are applicable to all inventions irrespective of the technology areas. Examination guidelines for each technology area indicate to the elaborateness of the practice in relation to patents. While preparing patent specifications for agriculture inventions, it is important to ensure that the subject matter claimed should not be a method of agriculture (under Section 3h) or plants or plant parts (under Section 3j of the Act). Identification of relevant prior art and its anticipatory value is very important for the assessment of novelty of inventions. Agriculture inventions which can lower the cost, be obtained by reduced number of steps and are environment friendly can be considered under ‘economic significance’ by the Indian patent office (under the purview of Section 2(1) ja). Adhering to the disclosure norms (as mandated under Section 10 of the Act) are also important. Inventors/applicants need to also consider the deposit requirements. The present work examines the relevance of IPR and expansion of the patentability criteria, disclosure norms and additional requirements in relation to agriculture. It will highlight the need for patent search as an integral requirement for research, the process of preparation of invention disclosures to enhance the innovative ability of academic institutions as well as researchers.
