The Development of a Special Purpose Drink Based on Nut Raw Materials

To support health, efficiency and active longevity, a person needs to provide the body with the micronutrients necessary for metabolic processes. They must consume food in quantities that correspond to the physiological needs of the individual. Analyses of consumer demand have found that the human diet throughout life often includes dairy products.However, whole milk is often poorly tolerated by both the elderly and people with lactose intolerance (hypolactasia).This article examined the selection of alternative energy sources, focusing on the example of a drink that uses plant raw materials.Thus, the recipe of a new fermented drink based on nut raw materials was developed. The optimization of the hydromodule for the drink preparation from peanuts and hazelnuts, according to the content of the main food components and organoleptic quality indicators, was carried out. The chemical composition of the developed drink was established, a portion of which met 20% of the daily recommended value of vitamin B1, 16.8% of the daily value of niacin, and 15% and 19% of the daily value of iron and magnesium, respectively. The possibility of producing a fermented drink with nut raw materials as a complete replacement of cow’s milk was therefore shown to be justified.

VOLUMETRIC PRODUCTION OF EUCALYPTUS SPP. CLONES UNDER DIFFERENT SPACING IN A SEVERE DROUGHT PERIOD IN THE SEMI-ARID REGION OF PERNAMBUCO, BRAZIL

The adaptation of Eucalyptus clones in the Chapada of Araripe, PE, Brazil was observed after implementing experiments with fast-growing forests. This region has a high demand for alternative energy sources due to the Gypsum Pole, basically maintaining its energy matrix from the exploitation of Caatinga vegetation. Therefore, as a way to increase the gains in volumetric productivity in planting Eucalyptus spp. clones, it is important to understand which spacing levels provide the best competition between individuals. Thus, the objective of this study was to evaluate if the volumetric productivity of Eucalyptus spp. clones is affected by different spacing levels in stands implanted under severe weather conditions in Chapada of Araripe, PE, Brazil. The experiment was carried out at the Experimental Station of the Pernambuco Agronomic Institute (IPA) in the municipality of Araripina, PE, Brazil. Three Eucalyptus clones (C11, C39 and C41) with five spacing levels (2 m x 1 m, 2 m x 2 m, 3 m x 2 m, 3 m x 3 m and 4 m x 2 m) were arranged in a completely randomized design with factorial arrangement (3 x 5). The survival rate of the experiment was higher than 94%, even under conditions of water stress. The highest volume productivity was obtained with the C39 clone in the 2 m x 1 m spatial arrangement. The spatial arrangement strongly influences productivity. Even with the severe drought condition regulating productivity, the C39 clone showed MAI values of 15.92 m3 ha-1 year-1.

Gender Ideologies and Climate Risk

Although African cities are nodes of scalable solutions to climate uncertainty, adaptation efforts rarely build on the gender-climate nexus for sustainability. This article examines how gender ideologies intersect with climate risks, based on case study findings from Kampala in Uganda. Climatic hazards in Kampala include prolonged dry spells and seasonal floods; which destroy infrastructure, contaminate air and lead to unprecedented spread of cholera and malaria. Both conventional and emancipatory gender ideologies are characteristic of how the gender-climate nexus shapes adaptation at neighborhood scale. Women, as custodians of domestic hygiene, navigate the health risks of flooding through trade-offs among competing uses of their time and labour, as men comply with the masculinity code of family safety to repair flooded homes and drainages. Emancipatory gender ideologies on the other hand are manifested by women's and men's agency to adopt alternative energy sources and urban greening that have potential for sustainability.

Impact of selected teleconnection pattern on solar energy potential in different climatic zones of Nigeria

Meeting the energy demands and sustainable development goals in Nigeria requires investigation of potentials of alternative energy sources and possible challenges to their reliability. In this study, we investigated the impact of four (4) teleconnection patterns on the solar energy potential within different climatic zones of Nigeria. Our results indicate that there are weak and insignificant correlation between the studied teleconnection patterns and solar energy potential on the long run. However, monthly analysis suggests significant correlation values between all the teleconnection patterns studied and solar energy production within all the climatic regions of the country. Therefore, it is important to consider the role of teleconnection pattern in energy planning and forecasting within the region.

Communications Technologies for Smart Grid Applications

Smart grid is a modern power grid infrastructure for improved efficiency, reliability, and safety, with smooth integration of renewable and alternative energy sources, through automated control and modern communications technologies. The smart grid offers several advantages over traditional power grids such as reduced operational costs and opening new markets to utility providers, direct communication with customer premises through advanced metering infrastructure, self-healing in case of power drops or outage, providing security against several types of attacks, and preserving power quality by increasing link quality. Typically, a heterogeneous set of networking technologies is found in the smart grid. In this chapter, smart grid communications technologies along with their advantages and disadvantages are explained. Moreover, research challenges and open research issues are provided.

Potential of tidal power plants on Tibo Beach with spektrum method

As time evolved, the demand for electrical energy also increased. As a result, renewable energy is needed to replace fossil fuels as fuel for electricity generation. Tidal water is one of the renewable alternative energy sources used as fuel for electricity generation. The tides will never run out and can also be predicted. One method that can predict data about waves is the Spectrum Method. Tide prediction data can be indicated by carrying out tidal height observations for 15 days at Tibo Beach, Donggala Regency, Central Sulawesi. Based on observations, the data obtained are the highest high water level (HHWL) is 2.4 meters, and the lowest low water level (LLWL) is 0.1 meters. Also, the type of tides on the Tibo coast is a type of mixed waves that tend to double daily, there are two tides with high water and two tides with low water with different water levels. Because the value of formzahl is 0.312. With a 2.4 meter high HHWL and a sea area of 35.4 km2, the electricity generated is 13.08 MW.

Legal aspects of the use of bioenergy in the European Union

The article explores the features of the legal regulation of bioenergy in the European Union, analyses the concepts of bioenergy and biofuels in Ukrainian and European legislation and highlights the main provisions of the European Union Directives, concerning the promotion of the use of energy from renewable sources, including biomass. In particular, bioenergy has been identified in the EU as the leading source of renewable energy for heating and cooling (88 per cent of all RES), representing 16 per cent of the total European final energy consumption in this sector. Consequently, in view of the demand for and the need to use such a resource, the EU legislative framework contains a number of principles (bases) and mandates for regulating the relationship in the area of manufacturing, handling and decontamination of waste biofuels as a primary feedstock for bioenergy. In particular, the fundamental principles of the EU bioenergy legislation are, first, the principle of sustainable production and consumption of biomass, and second, the prevention of reduction of negative impacts from the use of this resource, Third, increasing the share of alternative energy sources to 75 % of final energy consumption by 2050.
