Abstract:

Despite a very large variety of improvised firearms, repeatability of certain actions of the manufacturers can be observed, reflecting the purpose to which such weapons are produced (e.g. poaching), and the availability of appropriate technologies. The aim of this article is to make an attempt to systematize improvised firearms on the basis of the expert opinions elaborated at the Weapon Research and Ballistics Department of the Voivodeship Police Headquarters in Kraków (LK KWP) as well as studies carried out on weapons belonging to the collection of the Department of Forensic Medicine (ZMS) i

Abstract:

Simulating fragment penetration into steel involves complicated modeling of severe behavior of the materials through multiple phases of response. Penetration of a fragment-like projectile was simulated using finite element (FE) and meshfree particle formulations. Extreme deformation and failure of the material during the penetration event were modeled with several approaches to evaluate each as to how well it represents the actual physics of the material and structural response. A steel Fragment Simulating Projectile (FSP) – designed to simulate a fragment of metal from a weapon casing – was s

Abstract:

AbstractProjectile injuries to the face deserve particular attention to evaluate for involvement of critical structures and functional elements and treat the devastating effects on facial aesthetics. Ballistic trauma to the maxillofacial region often has significant soft tissue and bony defects, creating a greater challenge to the reconstructive surgeon. The main goals of treatment of projectile injuries to the face are decreasing the amount of contaminants and nonviable tissue at the site, ensuring functionality, and restoring aesthetic appearance. There exists a lack of robust research on th

Abstract:

In this paper we present the results of a use-wear study of quartz micro-notches identified during a technological analysis of lithics from the Howiesons Poort layers of Sibudu Cave. Building on the technological analysis and preliminary functional screening of the archaeological material, a series of experiments was designed to evaluate different hypotheses for notch formation (blank production, intentional notching, hafting, projectile use, and trampling). The experimental reference collection was compared with archaeological micro-notches and a large sample of other archaeological quartz pi

Abstract:

Maintenance of samples of weapons is carried out at the stages of their life cycle and is carried out on the basis of coordination of actions of the customer and the consumer with a wide range of organizations from the main developer to the co-executors, which does not exclude the occurrence of conflict situations. This leads to the problem of implementing the optimal synthesis of such a complex system and does not allow to direct efforts to achieve the extremum of the target function of the system as a whole. Therefore, the emergence of such a problem and the existing conflicts in the process

Abstract:

This study addresses the evolution and significance of forensic ballistics, highlighting its role in solving violent crimes, particularly in the context of the increasing homicide rates in Ecuador. Throughout the work, the methodological and scientific foundations underpinning forensic ballistics are examined, linking it to legal medicine and forensic traumatology. Recent technological advancements in this field, such as Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), 3D crime scene reconstruction software, and shooting pattern analysis, are discussed, demonstrating how the

Abstract:

AbstractLate Glacial and Early Holocene bone and antler artifacts are recovered from all over the Polish Lowland. Elements of projectile weaponry, in the form of various points made of osseous raw materials, were an important part of hunter-gatherer equipment of that time. We present the results of AMS dating of a unique collection of thirteen artifacts that had previously been chrono-culturally attributed by means of relative dating using typological approaches only. The results obtained are considered alongside current knowledge and typological arrangements for these types of tools in Europe

This research studies the factors that lead to India's military modernisation in Andaman and Nicobar Islands (ANI). The research focuses on the geostrategic elements of the ANI and the contemporary Sino-Indian relationship. This research has three objectives namely 1) to study the factors that led to India's military modernization, 2) to examine the impact of India's military modernisation on China and 3) to analyse the China's reaction to it. The theory of realism was applied to support the argument of Sino-Indian relations, as both countries have a particular interest in the Indian Ocean Reg

Abstract:

I remember the first time I saw a dead body. I spawned just before dawn; around me engines were clattering into life, the dim silhouettes of tanks beginning to move out in a steady grinding rumble. I could dimly make out a few other people, the anonymity of their shadowy outlines belied by the names hanging over their heads in a comforting blue. Suddenly, a stream of tracers arced across the sky; explosions sounded nearby, then closer still; a tank ahead of me stopped, turned sluggishly, and fired off a couple of rounds, rocking slightly against the recoil. The radio was filled with talk of Ge
