The development of the domestic engineering industry during the independence of Ukraine, in particular, led to the emergence of enterprises working in the field of development and production of firearms and ammunition for it. Experimental studies performed by forensic experts and criminologists to study the features of injuries and damage caused by modern models of domestic weapons need to be generalized and systematized. Aim of the work. To review the literature sources related to the study of lethal and non-lethal pistols and ammunition for them of domestic production. Materials and methods. In order to achieve this goal, we searched for literature sources within the scientometric databases of Google Scholar, Web of Science and Scopus by keywords, to a depth of 10 years using the criteria of selection of articles. Results. A review of literature sources revealed that the direction of the study of pistols and ammunition for them of domestic production is still relevant and tends to increase in the last 5 years; the departments of forensic medicine at Higher Education Institutions and Research Forensic Centers are most interested in studying this topic; publications on models of pistols developed 10 or more years ago are found in large numbers in the scientific literature, but publications on "younger" models in the scientific literature are not found. Conclusion. The vast majority of research on domestic firearms is devoted to the study of pistols produced by RPC «Fort». However, the available amount of research cannot meet the current needs of the expert service and, accordingly, the police. Research aimed at studying the ballistic properties of domestic weapons still remains a relevant and urgent area of forensic medicine and criminology.

Squat lobsters of the superfamilies Chirostyloidea and Galatheoidea are highly visible crustaceans on seamounts, continental margins, shelf environments, hydrothermal vents and coral reefs. About 1000 species are known. They frequently feature in deep-sea images taken by submersibles and are caught in large numbers by benthic dredges. Some species are so locally abundant that they form ‘red tides’. Others support a variety of important fisheries. The taxonomy of squat lobsters has been intensively studied over the past few decades, making them one of the best known deepwater crustacean groups. As a result, they have attracted the attention of deep-sea ecologists who use them as proxies to test hypotheses about deepwater ecological processes and biogeography. Interest in squat lobsters now extends much more widely than the taxonomic research community and this work is a timely synthesis of what is known about these animals. The Biology of Squat Lobsters provides keys for identification and reviews the current state of knowledge of the taxonomy, evolution, life history, distribution, ecology and fisheries of squat lobsters. A striking feature of squat lobsters is their vivid coloration, which is revealed in a selection of spectacular images of different species. 2012 Whitley Award Commendation for Invertebrate Natural History.

There is presented a review of scientific literature characterizing the main directions of modern research of the process of grinding of fibrous semi-finished products of high consistence. Theoretical approaches are described in the study of qualitative parameters of pulp during its processing in knife grinding machines. Researchers note an increase in the paper-forming properties of the pulp and the physical and mechanical characteristics of the finished product. This paper provides an overview of experimental studies of the high consistence pulp milling process. The effect of high consistence mass grinding intensity on the quality of the finished product is considered, the nature of fiber development when grinding high and low consistence mass is compared. Experimental studies show that an increase in the intensity of exposure when grinding a high consistence mass leads to a decrease in the tensile energy absorption index, and a decrease in the deformation of the paper sheet is also observed with an increase in the grinding intensity. With an increase in the pulp c consistence, a change in the degree of delamination, internal and external fibrillation of the fiber wall is observed. The high-consistence pulp milling process is accompanied by higher specific energy consumption compared to low- consistence pulp milling, but observations at the fiber wall level show a more developed external specific surface area. This review of the scientific literature will serve as a basis for further research on the grinding of high consistence fibrous materials.

Compare And Contrast

Many evolutionary theorists have enthusiastically embraced human nature, but large numbers of evolutionists have also rejected it. It is also important to recognize the nuanced views on human nature that come from the side of the social sciences. This introduction provides an overview of the current state of the human nature debate, from the anti-essentialist consensus to the possibility of a Gray’s Anatomy of human psychology. Three potential functions for the notion of species nature are identified. The first is diagnostic, assigning an organism to the correct species. The second is species-comparative, allowing us to compare and contrast different species. The third function is contrastive, establishing human nature as a foil for human culture. The Introduction concludes with a brief synopsis of each chapter.

Double Coating

The article presents a new functional method of designing self-compacting concrete (SCC). The assumptions of the functional method of designing self-compacting concrete were based on the double coating assumption (i.e., it was assumed that the grains of coarse aggregate were coated with a layer of cement mortar, whereas the grains of sand with cement paste). The proposed method is composed of four stages, each of which is responsible for the selection of a different component of the concrete mix. The proposed designing procedure takes into consideration such a selection of the mineral skeleton in terms of the volumetric saturation of the mineral skeleton, which prevents the blocking of aggregate grains, and the designed liquid phase demonstrated high structural viscosity and low yield stress. The performed experimental studies, the simulation of the elaborated mathematical model fully allowed for the verification of the theoretical assumptions that are the basis for the development of the method of designing self-compacting concrete.

This paper presents issues related to the adaptive control of the drive system with an elastic clutch connecting the main motor and the load machine. Firstly, the problems and the main algorithms often implemented for the mentioned object are analyzed. Then, the control concept based on the RNN (recurrent neural network) for the drive system with the flexible coupling is thoroughly described. For this purpose, an adaptive model inspired by the Elman model is selected, which is related to internal feedback in the neural network. The indicated feature improves the processing of dynamic signals. During the design process, for the selection of constant coefficients of the controller, the PSO (particle swarm optimizer) is applied. Moreover, in order to obtain better dynamic properties and improve work in real conditions, one model based on the ADALINE (adaptive linear neuron) is introduced into the structure. Details of the algorithm used for the weights’ adaptation are presented (including stability analysis) to perform the shaft torque signal filtering. The effectiveness of the proposed approach is examined through simulation and experimental studies.
