PLATE ARMOR FROM THE SHAKHRUKHIYA HILLFORT

В публикации рассматривается среднеазиатский доспех XV в., происходящий с территории позднесредневекового города Шахрухия. The paper explores a CentralAsian armor plate originating from Shakhrukhiya, a late medieval city. The find has been dated to the 15th century.

Findings on Kupchegen-1 Settlement (Central Altai)

The paper presents the results of the chronological attribution of a complex of objects obtained during exploration work at the Kupchegen-1 settlement, located on the outskirts of the village of the same name in the Ongudai district of the Altai Republic. The settlement is located on a small site in a closed hollow, in the place of a seasonal watercourse. Due to this location, the cultural layer of the site is destroyed by a large gully, in which the locals collected lifting material in the form of fragments of ceramic vessels, iron products, animal bones and pieces of slag. In 2020, the ravine was cleaned up and additional material was obtained, allowing the dating of the main layer of the settlement. Based on the consideration of analogies of individual finds, in particular, an iron armor plate, a ceramic complex and a blank quiver loop, the materials of the settlement were tentatively dated to the 9th-13th centuries AD. It is possible that the materials received also contain a few items related to other periods. The studied complex can become a reference for the study of the settlements of the Turkic and pre-Mongol times of Altai. Keywords: settlement; Middle Ages; Turkic time; pre-Mongol time; ceramics; quiver; armor plate Acknowledgements: The research was carried out with the financial support of the Russian Science Foundation (project No. 20–78–00035).

COMBINED METHOD OF MANUFACTURING ARMORED STEEL

Foreign and domestic experience has shown the prospects of using heterogeneous multilayer armor instead of homogeneous. Studies have shown that the method of explosion welding for low-plastic and high-strength steels has limitations on the thickness of the thrown plate of 10-12 mm, which allows us to recommend it for the production of multilayer composite armor. The combined technology (explosion welding + hot batch rolling) provides a three-layer armor plate with an intermediate layer of plastic steel with high strength properties and a defect-free joint structure. The introduction of layers of plastic metals into the composition of multi-layer armor makes it possible to increase the armor resistance. The combined technology can be recommended for the production of wear-resistant and armored bimetal.

Masculinized Male Chest Contouring: Creating the Armor Plate

Male patients are routinely consulted regarding dislike of their chest appearance. To date, majority of patients have desired elimination of their feminine-appearing breast, termed gynecomastia. These patients have associated their overweight body image, with the femininity of their breasts as presented by fullness and roundedness of their breasts and subsequently have desired maximal flattening of their breast. We present a new set of patients who desire a more muscular-appearing chest than a gynecomastia repair that is interposed on a chiseled abdominal contour. In contrast to the former set of patients, these patients desire bulking of their breasts with a bolder-appearing armor plate look. We present an alternative to traditional gynecomastia repair which involves a novel approach to chest contouring creating a flat, yet bold, pentagonal-shaped breast with linear borders utilizing both fat and gland removal as well as strategic fat grafting back into the chest. We present a novel protocol to create an armor plate male chest appearance as an alternative to traditional gynecomastia contouring. All patients treated to date demonstrate a muscular-appearing chest that is harmonious on an interposed masculine-appearing abdomen.

Modelling of the processes of impact of a projectile with elements of individual defence

A two-dimensional and three-dimensional non-stationary problem of the interaction of a homogeneous impactor and a heterogeneous structure made of steel and ceramics and placed in a Kevlar pocket is considered. The model of the human body is a plate of gelatine with cylindrical inserts-imitators of human bones. The results of numerical simulation using different approaches for describing heterogeneous media are compared. On the basis of direct numerical simulation, it is shown that the gradient armor plate (steel + B4C) has the best weight and size parameters.
