The research of a human food ration is caused by the great social significance in solving the problem of proper supply the population with food in the world countries. The food problem has a most evident geographic character. The world countries having at their disposal various agro-climatic conditions, demographic resources and population growth rates, socio-economic potential, specialization and labor productivity of agriculture production, are essentially distinguished by the food supply level of population and by structural characteristics of food ration. The formation particulars of the world countries population food ration were considered and characterized in the article. The key characteristics and factors of the world population's food ration were analyzed there. The geographic differences of food ration, as well as the world countries typology by distinctive features of food consumption through their division into groups (nutrition types) according to the content and quantity of basic components in food ration were determined in it.

Providing a favourable and comfortable living environment for the population is one of the main tasks of optimising urban development. The level of comfort is formed with the territorial interaction of natural and socio-economic conditions for the region’s development. This interaction is especially manifested in large industrial centres, characterised by a strong negative anthropogenic impact on the environment. The territorial assessment of the comfort of the living environment involves a comprehensive spatial analysis of the population comfort main factors. The purpose of this work is a spatial analysis of the population living comfort of one of the most industrialised regions not only Ukraine, but also Europe – the city of Kryvyi Rih. Functional zoning was carried out using GIS Map Info with the allocation of the following areas: residential zones, public and business zones, industry and warehouse zones, resort and recreation zones. The distribution of the residential area according to the level of comfort of the population living environment was carried out according to 3 groups of factors: transport accessibility, development of social infrastructure and ecological state. The first group characterises the habitat from the point of view of the city’s provision with transport routes for various types of public transport. The second group characterises the population’s social conditions, namely the number of educational, cultural and medical institutions. The third block includes the ecological state of the territory according to the criterion of atmospheric pollution. The method of scoring made it possible to compare individual parts of the area under study across the entire range of natural, ecological and social population comfort. The combination of indicators of the totality of all three groups factors was carried out using overlay operations. As a result of the research, a map characterising the spatial differentiation of indicators of the living comfort in the city of Kryvyi Rih has been created. The specialisation of the city as a large industrial centre has determined the leading role of the group of environmental indicators in the situational model of the living environment comfort in the region.

The issue of energy-saving and energy efficiency is actual at the present-day development of Ukraine's economy. The imperfective system of energy ensuring as the result of inefficient energy resources utilization is a characteristic feature of the state. The analysis of ensuring energy resources applied to Dnipropetrovsk Region as one of the leading industrial regions of the country is presented in the article. The availability of reserves and production of fuel resources was analyzed in it. Distinctive features of energy resources consumption with the aim of assessment general and partial indexes of energy ensuring and fuel power-intensity of the region's economic complex are highlighted in the work. The tendencies and perspectives of energy consumption development of the Dnipropetrovsk Region were analyzed herewith.

Infrared spectroscopy (IR) is a highly effective method for the analysis of minerals, rocks and ores, capable of solving a whole range of problems when choosing innovative solutions for the technological processing of various types of mineral raw materials. The article considers the main directions of using the infrared spectroscopy method in assessing the technological properties of minerals and their behavior in technological processes: evaluation of the grade (quality) of mineral raw materials; analysis of the behavior of minerals in the technological process with prediction of their technological properties; analysis of changes in the structure and properties of minerals in technological processes; operational analysis of mineral substances at various stages of technological processing. The article illustrates all aspects of the use of infrared spectroscopy at various stages of studying the material composition of mineral raw materials in its enrichment assessment by specific examples of solving problems arising from the technological redistribution of various types of ore and non-metallic minerals.
