Energy security, alongside with industrial, food, societal, environmental and sustainable development, information, cyber, economic, defense and national order security, etc., is part of the concept of national security of a state. The level of security of a state is the ability of that state to aggregate resources internally and gain or maintain access to external economic resources. Energy security means being ensured in terms of raw material sources, control of transportation and distribution routes and alternatives. Sufficient and available raw material resources are an urgent prerequisite for achieving energy security. Any longer interruption of energy supply has a negative effect on the economic growth, the political stability and the welfare of the citizens of a state. The following elements of energy security instability can endanger a state’s energy security: risks (physical, economic, geopolitical, geostrategic, social, environmental protection, etc.); threats (terrorist action, political, industrial, economic and national instability, armed conflicts, piracy, etc.); dangers (lack of energy supply and/or raw materials, the finite nature of energy resources, use of energy as a pressure instrument or energy weapon, use of energy revenues to support undemocratic regimes, high energy costs for developing countries and global climate change) and vulnerabilities (natural and/or anthropogenic hazards). For the purpose to ensure the stability of national and EuroAtlantic security, the following factors are proposed by authors to achieve and ensure energy security: 25 proposed way to achieving energy security; 8 proposed way to ensuring energy security, and 9 proposed scenarios to quantification energy security almost complete. The final conclusion is: the energy security of a state is in fact the national security of that state.

Any change of the raw material sources for glazes, economically, ecologically motivated, and also from the glaze quality point of view, is conditioned by the molecular formula rationalization and by the variation limits of the molecular formula, respectively. The proper glaze compositions are placed within their limit variation intervals with optimized processing and utilization properties. For this purpose, the rationalization criteria and procedures of molecular formulas are summarized in the present paper, as well as the results referring to their rationalization obtained in the authors� previous work. Thus, one starts from a base of raw materials that are selected, usable and also accessible for the design and producing of the glazes. On these bases the groundwork and the design equation for the glaze recipes are developed, exemplified for a single glaze. For an easy access to results, computer programs are used for an easy access to results.

Mining And Smelting

The subject of this research is the copper deposits, copper-ore resource, and sources of alloying raw materials for mining and smelting production of the Paleometal Epoch in Central Kazakhstan, namely within the Kazakhstan mining and smelting region and Zhezkazgan-Ulytau mining and smelting center. The article provides the interim results of comprehensive research of geoarchaeological production facilities in the territory of copper deposits within the Zhezkazgan-Ulytau mining and smelting center, which allow determining the peculiarities of metallogenic complexes that used to be potential objects of the development of copper-ore reserves during the establishment of copper metallurgy, as well as making a predictive assessment of mineral raw materials potential of the region. The initial premise of this research lies in the authors' pursuit to integrate natural scientific methods of research into the field of humanities to the maximum effect via studying smelting slags and ore relics from the ancient settlements of the region for the purpose of reconstructing the mining and smelting process of the Bronze Age in Central Kazakhstan. The authors offer the variants of localization of the mineral raw materials complex of Zhezkazgan-Ulytau mining and smelting center within the Kazakhstan mining and smelting region. Based on examination of the ores and smelting slags of Bronze Age settlements in Central Kazakhstan, the authors believe that the main copper raw materials in the Zhezkazgan-Ulytau region were the oxidized malachite-azurite and rich sulfide ores, as well as the zones of secondary sulfide enrichment of copper sandstones of the Zhezkazgan ore region. The conducted research allow to get closer to establishing patterns of localization of various types of copper deposits and development of copper-ore resources for mining and smelting production of Zhezkazgan-Ulytau region during the Paleometal Epoch.

The causes of the global vanadium consumption increase are described and new applications of this metal are given in the article. The main natural sources of vanadium are titanomagnetite, which is a strategic mineral raw material. The current volumes of vanadium extraction from natural raw materials do not match the demand of the market. Therefore there is an urgent need for recycling of secondary and technogenic sources. Partially the basic existing technologies processing vanadium-containing waste are reviewed. The effect of these wastes on the environment and human health is analyzed. The importance of vanadium steel slag recycling for the ecological state of industrial regions, resource-efficiency in expanding the raw material sources of vanadium and reducing the cost of steel production in general is shown. The results of studies on the extraction of vanadium in the form of soluble vanadate of metallurgical vanadium slag using hydrometallurgical processing are demonstrated. The analysis of the received values of the vanadium extraction degree was conducted. The influence of various factors on the completeness of extraction was examined. A significant influence on the vanadium extraction degree of slag chemical composition, the ratio of slag and alkaline additives in the charge, conditions of roasting and leaching was revealed.

Drying Up

A historical overview shows that mankind has feared the scarcity of mineral resources, especially metals, for many centuries. In the first half of the 20th century, this discussion was marked by the great military demand for raw materials, followed by the growing world population, increasing consumption and environmental awareness. From then on, there was less talk of regional shortages, but more discussion of a global scarcity or even a drying up of raw material sources worldwide. Although these forecasts are still controversially discussed today, the assessment of resource depletion has become an integral element of Life Cycle Assessments (LCA) or Life Cycle Impact Assessments (LCIA) of product systems. A number of methodological approaches are available for this purpose, which are presented and applied in a series of articles as part of a special issue of ”Resources”. The fundamental question is also addressed, namely to what extent the assessment of resource depletion in the context of an environmental study such as LCA is appropriate.

Today in Ukraine the share of low-quality bakery products is near 20–25 %, because they often don’t correspond to quality standards and sanitary norms, because of being produced of flour with low bakery properties. That is why new raw material sources, functional ingredients and so on are searched for in bread technologies. For using new raw material and food supplement types, it is necessary to know their functional-technological properties (FTP) that allows to prognosticate the behavior of powder-like raw materials and food supplements in food masses at technological processing and storage of ready products. The water-retaining capacity (WRC) is one of main functional-technological parameters of carbohydrate-containing raw materials, because it favors the outcome, structural-mechanical properties and quality characteristics of ready products. The authors introduced “Magnetofood” polyfunctional food supplement for increasing WRC of rye-wheat dough. For grounding the mechanism of forming supramolecular groups in carbohydrate food systems: Magnetofood-polysacharide-water, there was studied the influence of “Magnetofood” food supplement on processes of hydration, swelling and water-retention by rye-wheat starch and rye-wheat flour. It was established, that introduction of “Magnetofood” food supplement in rye-wheat starch and flour in amounts: 0,10; 0,15; 0,20 % to the mass of starch or flour increases swelling and water-retaining capacity (WRC) of starch and flour: swelling in 1,3–1,5 and 1,5–2,25 times, respectively; WRC in 1,10–1,15 and 1,1–1,3 times, respectively. The rational dose of “Magnetofood” food supplement – 0,15 % to the mass of dry raw material was experimentally set. There was studied the influence of “Magnetofood” food supplement on rheological properties of water suspensions of rye-wheat starch and flour at different temperatures and different speeds of shift. It was established, that adding “Magnetofood” in amount 0,15 % favors increasing the effective viscosity of suspensions of experimental samples of starch and flour at temperatures: (23±2) ºС and (40±2) ºС comparing with control samples in average by 29,0 % – for starch and by 22,0 % – for flour at 23 °С and by 16,0 % – for starch and by 10,0 % – for flour at 40 °С. There was studied the dynamics of changing viscosity of colloid solutions of starch and flour, enriched with “Magnetofood” in amount 0,15 % to the mass of dry raw material in the keeping process at different temperatures and shift speed 9 s-1. There was established the increase of viscosity of suspensions of rye-wheat starch and flour in the process of infusion (especially at adding “Magnetofood”) that is connected with continuing hydration and swelling process. It was demonstrated, that the temperature increase of the colloid system from (23±20) ° С to (40±2) °С favors the increase of its viscosity – both at the initial moment and in infusion process during 30 min in average by 20,0–25,0 % at the expanse of the aforesaid processes. Moreover, adding “Magnetofood” accelerates and intensifies the processes of swelling and hydration of experimental samples of rye-wheat starch and flour comparing with control ones. The received experimental data may be used at elaborating the technology of rye-wheat bread, enriched with “Magnetofood” food supplement; and also at elaborating innovative technologies of carbohydrate food systems. The results of this study may be used at elaborating recipes and technologies of carbohydrate-containing food products for increasing their viscosity, water-retaining and stabilizing capacities.

Critical Raw Materials

The presented article deals with the issue of critical raw materials in the European Union with an emphasis on sustainable development and also barite, as an only one critical raw material mined in Slovakia. The article points out in detail the deposits of individual critical raw materials within the European Union. They clearly profile the European area´s dependence on imports of critical raw materials in accordance with the Communication from the Commission to the Council, the European Economic and Social Committee and the Committee of the Regions on the European Union's list of critical raw materials. Based on a defined Herfindahl-Hirschman index, which is clearly methodologically described, the article also points to the exploitation of critical raw materials in the European Union, what is in consideration of sustainable development crucial because some inventions are fundamentally dependent on them, as is their production on world markets. This article deals with critical raw materials in the EU, because it is in this area that we would like to experience the 4th industrial revolution, which is characterized by "new products" with a short life cycle, products with the least possible impact on the environment, i.e. innovations that are often impossible without important raw materials. Is it at all possible to talk about sustainable development with such raw material sources in European Union?

Oil And Natural Gas

The energy sector is an example of an unusual branch of the economy whose success largely depends on the amount of energy carriers owned by a given country. Paying attention to Poland, it should be noted that next to hard coal, which is the largest quantity of raw material, the role of oil and natural gas is steadily increasing. Energy security gives the opportunity for development in individual countries only if it can function and satisfy basic goods that allow economic prosperity. These goods include, but are not limited to, energy resources, which may determine the prosperity of individual economic sectors. In turn, energy carriers along with other raw materials decide about the level of fuel security of the country, and thus affect the level of energy security. However, due to the existing threats to this sector, one of the important roles is played by the Police, which counteracts all criminogenic phenomena that deplete the economic benefits for the state from the fuel sector. The article is an interesting supplement to the issues raised in the journal, because it draws attention to a special problem that should be tackled not only on a national, but also international scale, so the text seems to be important from the perspective of the topics discussed. In addition, the issues raised, which are not so often discussed in the scientific literature, constitute an interesting supplement in the field of matter.

Chapter 13 examines the evidence for Early Archaic use and settlement of the inter-riverine zone between the Savannah and the Santee Rivers, both of which are the major alluvial rivers on southern Coastal Plain of South Carolina. Heretofore little work has been done in this zone. Several large, private collections, forming a transect, are analyzed for diagnostic hafted bifaces – or various stone tools – including their raw materials. The entire Early Archaic tool kit is found in this zone, though with relatively low density sites. Based on raw material sources, a considerable going back and forth between these major rivers is indicated.

Application of Halal Standard HRN BAS 1049:2010 in production of Sujuk The application of the Halal Standard HRN BAS 1049:2010 in the production of Sujuk is prescribed by the implementation of HACCP system and the certification issued by the Centre for Halal Quality Certification. The paper presents halal standard requirements in the course of Sujuk production from raw materials to finished products. Sujuk is a traditional dry, spicy sausage originating from Bosnia and Herzegovina consisting of ground beef with the addition of various spices (sumac, garlic, salt, red pepper). The production of Sujuk is based solely on raw material sources awarded the halal certification. The process of production prevents the cross contamination of halal (permitted) and haram (prohibited) raw materials and products by defining the 5 HrCCP (Haram Critical Control Points): HrCCP1 – procurement, reception and storage of raw materials, HrCCP2 – raw material preparation, HrCCP3 – production of sausage meat, HrCCP4 – smoking, HrCCP5 – storage of finished products. The halal quality certification may only be awarded to a product produced in accordance with the requirements of the Halal Standard HRN BAS 1049:2010.
