RESEARCH OF FUNCTIONAL AND TECHNOLOGICAL PARAMETERS OF HIGH PRESSURE PROCESSED MEAT

High hydrostatic pressure (ННP) technology has been widely used in the developed countries food industry for production and preservation of raw materials and products. In our country the possibility of a new processing method is being now tested only on experimental installations. For research we selected a pressure range from 200 to 700 MPa, the exposure duration at room temperature was 20 minutes. This article presents the results of the high pressure impact on pH, water-binding capacity of broiler chickens meat, moreover comparative assessment of range of losses that occur during heat treatment and high hydrostatic pressure were analyzed. The dynamics of change of the ultimate sheer stress depending on the ННP value is shown. It is established that the new technology in the selected range does not significantly affect the pH value. However the value of water-binding capacity increases along with increasing of pressure: during processing by 200 MPa it increases by 10.5%, within the range of 200–300 MPa it increases by additional 3.0%, and within the range from 300 to 700 MPa the value increased only slightly. Significant changes were observed in the determination of losses while technological processing of meat. Thus the losses during conventional boiling of broiler chickens fillets were 28.5% higher than during high-pressure processing. It is noted that within the range of 200–700 MPa this parameter increases by only 4.8%. As the pressure increased, the texture of the meat becomes denser, as evidenced by the results of the study of the structural and mechanical properties of the raw material. Based on the results of the implemented work, it is recommended to use ННP technology within the range of 600–700 MPa, processing time of 20 min at 20±1 ºС for production of poultry meat products

New design of cutters for coal mining machines

The author designs an up-to-date rock cutter for mining machines and presents a matrix to determine its service life depending on the strength of the rock being broken. The dependence of the cutter service life on the strength of the rock being broken is proved. Advanced designs of rock cutters by the leading companies are described. The author develops an original design of a rock cutter which provides greater cutting surface, increased strength and prolonged service life. Pilot samples of the cutters ready to the test run are presented

GWAS of random glucose in 476,326 individuals provide insights into diabetes pathophysiology, complications and treatment stratification

Conventional measurements of fasting and postprandial blood glucose levels investigated in genome-wide association studies (GWAS) cannot capture the effects of DNA variability on ‘around the clock’ glucoregulatory processes. Here we show that GWAS meta-analysis of glucose measurements under nonstandardized conditions (random glucose (RG)) in 476,326 individuals of diverse ancestries and without diabetes enables locus discovery and innovative pathophysiological observations. We discovered 120 RG loci represented by 150 distinct signals, including 13 with sex-dimorphic effects, two cross-ancestry and seven rare frequency signals. Of these, 44 loci are new for glycemic traits. Regulatory, glycosylation and metagenomic annotations highlight ileum and colon tissues, indicating an underappreciated role of the gastrointestinal tract in controlling blood glucose. Functional follow-up and molecular dynamics simulations of lower frequency coding variants in glucagon-like peptide-1 receptor (GLP1R), a type 2 diabetes treatment target, reveal that optimal selection of GLP-1R agonist therapy will benefit from tailored genetic stratification. We also provide evidence from Mendelian randomization that lung function is modulated by blood glucose and that pulmonary dysfunction is a diabetes complication. Our investigation yields new insights into the biology of glucose regulation, diabetes complications and pathways for treatment stratification.</p

Financial engineering of infrastructure projects : the concessional mechanism

Purpose: The article considers the model of financial engineering, in which financial resources for an infrastructure project are formed based on syndicated loans. Design/Methodology/Approach: The study is based on modern concepts of uncertainty and risk management theories and the concept of digital economy. It includes a system and diagnostic analysis, methods of financial analytics as well as quantitative and qualitative risk assessment methods. Findings: Authors analyzed the investment in the infrastructure projects development in the Russian Federation. The railways' export potential is analyzed and determined to depend on coal and container terminals. Authors highlighted the need for business consolidation and new infrastructure projects based on technologies of digitalization in the transport industry, reviewed the strategic importance of concession agreement for the construction of “Northern Latitudinal Railway”. Practical Implications: The research findings revealed that implementation of large infrastructure projects is capable to render breakthrough effect on GDP and economic growth rates of the Russian Federation. The adjusted experience could be introduced in the transport framework of the Russian Federation and abroad. Originality/Value: The main contribution of this study is in the highlighting features of concessional mechanism in the framework of large infrastructure projects.peer-reviewe

Environmental Improvement Of Opencast Mining

Existing classifications of waste dumps in the quarries are given and their phenomenological nature is clarified. The need to identify the essence of the term "dump" is shown as well as the idea of "dump" as an artificial formation with everted and mixed rocks distanced from the quarry. Essential classification of man-made rock formations in quarries is developed. Characteristic of variations of man-made waste formations in quarries is developed. To reduce harmful effects of open-pit mining, dumps should be substituted with strat-lays - man-made structures relevant to natural stratification of litho-substances. Construction of strat-lays would improve ecological and technological culture of open cast mining
