Assuming that the natural gauge group of gravity is given by the group of isometries of a given space, for a maximally symmetric space we derive a model in which gravity is essentially a gauge theory of translations. Starting from first principles we verify that a nonlinear realization of the symmetry provides the general structure of this gauge theory, leading to a simple choice of dynamical variables of the gravity field corresponding, at first-order, to a diagonal matrix, whereas the non-diagonal elements contribute only to higher orders.

SummaryTissue factor (TF) initiates coagulation and its expression in vascular smooth muscle cells (VSMC) likely plays a role in the propagation of arterial thrombosis. We report cloning the cDNA and proximal promoter region of the rat TF gene. While maintaining the general structure and organization of the TF molecule, there is a surprising divergence (≈ 18%) between the derived amino acid sequences of the rat and mouse TF. In contrast, there is striking similarity (90%) in the 5’ untranslated regions. High levels of basal promoter activity were seen in rat VSMC with constructs containing 106 bp of sequence downstream from the putative transcription start site and 426 to 103 bp of upstream sequence. Deletion of the sequence from −103 to −79, containing a single SP1 site, removed virtually all of the basal and serum-induced activity. Removal of the NFkB site or two additional upstream SP1 sites had little effect on serum responsiveness. Removal of the 5’ untranslated region abolished most of the basal activity of the TF promoter, suggesting that its high degree of conservation may be due to the presence of transcriptional elements critical for TF expression in rodent VSMC.

The article presents an example model of a seminar on the topic of the connection between three phenomena: poverty, deviant behavior, social exclusion. Taking into account the general parameters valid for the whole community, the attention is focused on the specific dimensions in children. The general structure follows the logic: from the identification of the problem in its essence, through its causal connection, to the approaches to dealing with it. The possibilities and limitations in principle and in individual cases that affect the analysis and methodological decisions are taken into account – e.g. some popular stereotypes and prejudices. The model can be used both in the form of the above – in the training of students – future specialists in pedagogy and social activities, as well as for work with current specialists in practice.

Objective: to conduct pharmacoepidemiological analysis and analysis of the costs of pharmacotherapy, taking into account the actual consumption of drugs in the real inpatient clinical practice at the federal center in Russia. Materials and methods. Data from the medical records of 14 patients with burn injury, who were hospitalized in 2018, was analyzed. Patients’ age was from 23 to 67 years (44,93 ± 14,66). Duration of hospitalization was from 17 to 62 days (35,93 ± 14,17). We calculated rate of prescription foe each drug and its share in general structure of all utilized drug courses (n = 460). We performed frequency analysis of prescription structure, DDD (defined daily doses) analysis, DU90% (Drug Utilization 90%) analysis, ABC-analysis and analysis of average cost of pharmacotherapy. Results. Most frequently used drugs, prescribed in 75-100% of all hospital cases, included 15 names, e.g. 2 antimicrobial drugs (vancomycin and amikacin), 19 were used commonly, including 4 antimicrobial drugs (co-trimoxazole, cefoperazone/sulbactam, tigecyclin and cefepime). Other drugs were used in less than 25% of cases. 33 drugs made 90% of all consumed NDDD, including 5 antimicrobial drugs (vancomycin, amikacin, co-trimoxazole, cefoperazone/sulbactam and tigecyclin). These drugs comprised 70,24% in the prescription structure. The cost of one DDD in DU90% segments (512,33 rubles) is 1,4 higher than in DU10% segment (649,34 rubles). Average cost of drugs included in DU90% group was 4735,89 rubles vs 4966,80 rubles for drugs from DU10% group. This finding shows positive tendency of burn injuries pharmacological treatment. Conclusion. We obtained the data, which can be used for comparison of real clinical practice costs with a current payment rates for medical care.

Energy Potential

Exhaustion of traditional energy resources, their uneven geographical location, and catastrophic changes in the environment necessitate the transition to renewable energy resources. Moreover, Ukraine's economy is critically dependent on energy exports, and in some cases, the dependence is not only economic but also political, which in itself poses a threat to national security. One of the ways to solve this problem is the large-scale introduction and use of renewable energy resources, bioenergy in particular. The article summarizes and offers methods for assessing the energy potential of agriculture. In our country, a significant amount of biomass is produced every year, which remains unused. A significant part is disposed of due to incineration, which significantly harms the environment and does not allow earning additional funds. It is investigated that the bioenergy potential of agriculture depends on the geographical distribution and varies in each region of Ukraine. Studies have shown that as of 2019 the smallest share in the total amount of conventional fuel that can be obtained from agricultural waste and products suitable for energy production accounts for Zakarpattya region - 172.5 thousand tons. (0.5% of the total) and Chernivtsi region - 291.3 thousand tons. (0.9%). Poltava region has the greatest potential - 2652.2 thousand tons. (7.8%) and Vinnytsia - 2623.7 thousand tons. (7.7%). It should be noted that the use of the energy potential of biomass in Ukraine can be called unsatisfactory. The share of biomass in the provision of primary energy consumption is very small. For bioenergy to occupy its niche in the general structure of the agro-industrial complex, it is necessary to develop mechanisms for its stimulation. In addition, an effective strategy for the development of the bioenergy sector of agriculture is needed. The article considers the general energy potential of agriculture, its indicative structure. The analysis is also made in terms of areas. In addition, an economic assessment of the possible use of existing potential is identified.
