Algorithms for determining the circumstances relevant for the case in the software for informational-technological support of judicial decisions

Objective to create a computer program of information technology support for making motivated court decisions to obtain constructive criticism of the grounds of and objections to claim presented in the software forms in order to improve it. Methods general dialecticalmaterialistic method in translating the law enforcement process into the language of information technology analysis and synthesis of the law enforcement process formal legal method for translating the requirements of the law and legal science to law enforcement into the program to be used by the judge and case participants objectoriented approach to modeling objectoriented programming methodology relational approach to database design. Results a part of the computer program is created for making motivated court decisions on cases of claim proceedings under the rules of civil proceedings solving the tasks of Article 148 of the Civil Procedural Code of the Russian Federation. Scientific novelty for the frst time a part of a computer program is presented which obliges the judge to take into account all the arguments of the parties regarding the circumstances to be established in the case to draw conclusions on them and in parallel with the conclusions and arguments of the judge for each choice to make a reasoned decision. It seems that the workload of the courts can be eliminated by the software for making and motivating court decisions which will signifcantly reduce the time for its production. The program has no analogues among the software solutions of legal disputes aimed at determining the circumstances relevant to the case. Practical significance the presented part of the program shows how a judge and case participants determine the legally signifcant circumstances of the lawsuit which are subject to proving and justifcation. The generated list of circumstances forces by the program logic to make a reasoned conclusion about the proofs and legal relevance of each circumstance. The interim fndings determine the solution for the claim

Imitation model of the electric trolley overhead crane

The article focuses on the analysis of the interaction between electric trolley and the cargo of the overhead crane. The influence of static and dynamic forces on the movement of the trolley and the cargo is examined, the reasons for the free fluctuations of the cargo are investigated. A computer model for studying the interaction of the cargo and the electric drive of the trolley is presented.В статье основное внимание уделяется анализу взаимодействия электропривода тележки и груза мостового крана. Рассматривается влияние статических и динамических сил на движение тележки и груза, исследуются причины свободных колебаний груза. Представлена компьютерная модель для изучения взаимодействия груза и электропривода тележки

Bone remodeling markers after experimental augmentation of trabecular bone defects with resorbable and non-resorbable osteoplastic materials in rabbits

To study the effect of bone defect augmentation on the dynamics of bone remodeling markers. Material and methods The effect of resorbable xenoplastic material (RXM), synthetic beta-tricalcium phosphate (b-TCP), porous titanium implant (PTI) and nanostructured carbon implant (NCI) on the markers of bone remodeling (osteocalcin, OC; bone alkaline phosphatase, BALP; C-terminal telopeptide of type I collagen, CTX-1) and inflammation marker (C-reactive protein, CRP) was investigated using bone defect model in rabbits. 24 animals were divided into 4 groups (n = 6 in each group) according to the type of osteoplastic material. Control group (n = 6) was without augmentation. An impression fracture of the proximal tibia was modeled. Blood samples were taken on days 1, 3, 7, 14, 45, 90, 180 after surgery. Results CTX-1was not detected in the control, b-TCP, PTI, and RXM groups after 90 days, but in the NCI group CTX-1 remained elevated until the end of the study. OC in the control, b-TCP, PTI groups reached a maximum at 14-45 days. No significant increase in OC was found in the NCI group. The BALP in the control group peaked at 90 days. In the b-TCP and PTI groups the concentration of BALP increased more rapidly. The dynamics of CRP in the RXM, b-TCP and PTI groups was similar to the dynamics in the control group, in the NCI group an increased level of CRP remained until the end of the study. Conclusion When a bone defect was augmented with both resorbable b-TCP and nonresorbable PTI, high osteogenesis activity and low osteoresorption activity were detected. The use of xenoplastic material did not reveal any advantages in comparison with surgery performed without augmentation. An increase in osteoresorption and a low level of osteogenesis were found by using NCI. © Yildiz K., Yildiz V., 2020

Benefits of insect colours: a review from social insect studies

Insect colours assist in body protection, signalling, and physiological adaptations. Colours also convey multiple channels of information. These channels are valuable for species identification, distinguishing individual quality, and revealing ecological or evolutionary aspects of animals’ life. During recent years, the emerging interest in colour research has been raised in social hymenopterans such as ants, wasps, and bees. These insects provide important ecosystem services and many of those are model research organisms. Here we review benefits that various colour types give to social insects, summarize practical applications, and highlight further directions. Ants might use colours principally for camouflage, however the evolutionary function of colour in ants needs more attention; in case of melanin colouration there is evidence for its interrelation with thermoregulation and pathogen resistance. Colours in wasps and bees have confirmed linkages to thermoregulation, which is increasingly important in face of global climate change. Besides wasps use colours for various types of signalling. Colour variations of well chemically defended social insects are the mimetic model for unprotected organisms. Despite recent progress in molecular identification of species, colour variations are still widely in use for species identification. Therefore, further studies on variability is encouraged. Being closely interconnected with physiological and biochemical processes, insect colouration is a great source for finding new ecological indicators and biomarkers. Due to novel digital imaging techniques, software, and artificial intelligence there are emerging possibilities for new advances in this topic. Further colour research in social insects should consider specific features of sociality. © 2020, The Author(s).We are warmly thankful to Stefan Pinkert and the anonymous reviewer, whose critical comments and suggestions helped to increase the quality of the manuscript.
