The article outlines problematic issues of dismantling cartridges in relation to small arms of large caliber, cartridges loaded with special bullets, particular types of silent bullets, non-combat cartridges. The article also highlights issues of optimizing actions of a forensic expert while research, the objects of which are products that are structurally similar to small arms cartridges, but loaded with propellants, pyrotechnic mixtures, poisonous substances, along with products that coincide with small arms cartridges in size and partially in design. \u0000Backlog of approaches incorporated in the current methodology for researching ammunition is identified in the article and practical need for updates and additions is actualized. \u0000Proposals were raised to amend the Methodology aimed at increasing safety of forensic firearm examinations, regulating actions of a forensic expert in deciding on dismantling cartridges. It is suggested to use modern devices for reloading cartridges in forensic practice to provide a better and safer research. A procedure for a forensic expert course of action while study of cartridges which are sent for forensic examination in a single copy to minimize the impact on both the object under study and its components, is proposed.","PeriodicalId":340932,"journal":{"name":"Theory and Practice of Forensic Science and Criminalistics","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132969094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Correctness indicator of the method, as a measure of deviation from a true value, was 6.5% volume while studying the model sample. As an auxiliary method for qualitative determination of gasoline or diesel fuel, the method of fractional distillation (distillation) at atmospheric pressure was used. \u0000Determination of the fractional composition of the mixtures was carried out under normal conditions for charge stocks as well as their mixtures with a concentration range of predominantly 10% volume. Research has shown a significant increase in the final boiling point temperature with availability of even a small amount of diesel fuel in gasoline as well as decrease in the initial boiling point when adding gasoline to diesel fuel. \u0000The study by gas-liquid chromatography method made it possible to establish an approximate boundary of gasoline components redistribution: diesel fuel mixtures when their proportions are changed. It was noted that the main redistribution of components occurs before and after adding n-Nonane which content in gasolines and diesel fuels is relatively small. Using the ratio of the sum of point areas eluting before n-Decane (without n-Nonane) and after n-Decane (including n-Nonane), considering unidentified ones, as the distribution coefficient of the source k components , it was possible to establish proportions of source components. \u0000The k coefficient dependence on the content of diesel fuel is nonlinear. Transition to linear relationship in the coordinates of the linear logarithm of the k coefficient and the content of diesel fuel showed the presence of strong negative correlation with the values of the coefficient of reliability of approximation from -0.982 to -0.997 for model mixtures. The practical application of the k coefficient to determine the content of gasoline and diesel fuel can be recommended when constructing narrow calibration dependences in the range from 20 to 40% (vol.) of the target component.","PeriodicalId":340932,"journal":{"name":"Theory and Practice of Forensic Science and Criminalistics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128535685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking into account full complexity of investigative activities encompassing a variety of interpersonal interactions, special attention is paid to the issue of psychological training of law enforcement agencies. Long-term perception of antisocial phenomena and communication with representatives of different social classes under conditions of time pressure and strict procedural regulation by investigator can result in increased mental stress in investigator and, as a result, in professional deformation. The investigator, being under the influence of negative emotions, must be able to maintain emotional stability. In this regard, the intellectual, volitional and communicative personal qualities of an investigator are particularly important. Keeping in touch with other participants of criminal proceedings, an investigator must maintain rationalism and composure, avoid formalism and bias. The purpose of such communication is to obtain information contributing to the establishment of truth on a specific criminal proceeding. The main task of an investigator in this process is to establish psychological contact with the use of psychological influence methods.","PeriodicalId":340932,"journal":{"name":"Theory and Practice of Forensic Science and Criminalistics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128686305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is argued that according to the evidence classification, the forensic opinion belongs to personal sources of evidence and, if there are no grounded reasons for disagreement with it, should be taken for granted and used in evidence as a result of research work of an authoritative specialist.

The procedure of preparing to the appointment of forensic molecular genetics examinations is a significant stage of forensic examination. It should be carried out at an appropriate level. The errors made by investigators while the detection, collection of biological origin samples, their storage and transportation exclude the possibility of solving identification problems, and sometimes the accomplishment of criminal proceedings tasks, what necessitates the need to develop recommendations aimed at eliminating them. The article purpose is to identify the modern capabilities of forensic molecular genetics examinations in the investigation of murders initiated due to murders, determining typical errors, which are made by prosecutors at the stages of preparation and appointment of the indicated examinations and the development of recommendations for their prevention and elimination. Ensuring the elimination and prevention of errors that are made by investigators, as well as the prevention of processes of DNA contamination and degradation are possible due to increase in the level of investigators’ special knowledge and the formation on this basis of skills for conducting appropriate investigative (search) and procedural actions. It is possible thanks to the involvement of forensic experts in the field of genetics while carrying out these actions, as well as in the case of appointing a group of investigators on indicated criminal proceedings.
