Technological Analysis

One of the problems in archaeology of Kazakhstan is the uneven study of the sites belonging to different epochs. For example, in Central Kazakhstan there is a clear bias towards the study of antiquities of the middle and late Bronze Ages, Early Iron Age and Middle Ages. The study of the Stone Age stopped since the 90-es of XX century, the Early Bronze Age is practically not investigated. This article publishes the results of technical-technological analysis of the ceramics of the Grenada camp (Karaganda, Kazakhstan) dated from the late Chalcolithic to the beginning of the Early Bronze Age. Author studied raw materials (three kinds), the clay paste composition (six recipes), the features of the design of the beginning (two programs) and the hollow body. The diversity of pottery traditions, marked for all levels of ceramic production, speaks of the heterogeneous composition of the camp population. The vessels belonged at least to two groups of different origin. Mixed recipes with gruss and grog in the presence of pure demonstrate this process of cultural mixing that took place within the camp. The conclusion is made that the materials of the Grenada camp, including the features of pottery traditions, reflect the complexity of the cultural-historical processes that have taken place in the territory of the Central Kazakhstan in the end of Chalcolithic - in the beginning of Early Bronze Age.

Abstract The inclusion of polysaccharide thickeners in the recipes of sweet dishes increases the functional reserves of the body, contributes to the preservation of health and the prevention of diseases. The purpose of the research is to study the sensory characteristics of polysaccharides of various nature when combined with food acids, to develop a recipe for a basic mixture of low-calorie meals for public catering. The authors analyzed citric, lactic and succinic acids in combinations with polysaccharides of various nature. Organoleptic tests were evaluated by a touch panel. The organization of the tasting analysis corresponded to GOST ISO 6658-2016; the consistency was determined according to GOST 31986-2012, GOST ISO 11036-2017, GOST ISO 8588-2011. The optimal organoleptic combinations of the presented food acids and complex additives of sweeteners (CDP) were identified, which included aspartame, sodium saccharinate, Sucralose, sweetness coefficient – 340: the mixture with citric acid had a long pleasant aftertaste without foreign tastes and the best taste characteristics. Using the “A-not A” method, we found that the sample with the addition of CDP is identical to the sucrose solution. In the second part of the study, polysaccharides were added to model samples of acids with complex sweeteners; the best sensory characteristics were obtained by model samples consisting of a mixture of low-esterified Apple pectin with lactic acid and KDP. The technology of obtaining a stable elastic jelly using low-esterified Apple pectin has been developed, since the complex mixture of sweeteners and food acids does not have a dehydrating effect. Developed a dry mix recipe that can serve as a basic development, low-calorie sweet products for catering and has a variance of use of lactic and succinic acids, depending on the flavor characteristics of the raw materials used and its corrective ability.

Phenol–formaldehyde (PF) resin continues to dominate the resin industry more than 100 years after its first synthesis. Its versatile properties such as thermal stability, chemical resistance, fire resistance, and dimensional stability make it a suitable material for a wide range of applications. PF resins have been used in the wood industry as adhesives, in paints and coatings, and in the aerospace, construction, and building industries as composites and foams. Currently, petroleum is the key source of raw materials used in manufacturing PF resin. However, increasing environmental pollution and fossil fuel depletion have driven industries to seek sustainable alternatives to petroleum based raw materials. Over the past decade, researchers have replaced phenol and formaldehyde with sustainable materials such as lignin, tannin, cardanol, hydroxymethylfurfural, and glyoxal to produce bio-based PF resin. Several synthesis modifications are currently under investigation towards improving the properties of bio-based phenolic resin. This review discusses recent developments in the synthesis of PF resins, particularly those created from sustainable raw material substitutes, and modifications applied to the synthetic route in order to improve the mechanical properties.

AbstractRuins are a statement on the building materials used and the construction method employed. Casa Ippolito, now in ruins, is typical of 17th-century Maltese aristocratic country residences. It represents an illustration of secondary or anthropogenic geodiversity. This paper scrutinises these ruins as a primary source in reconstructing the building’s architecture. The methodology involved on-site geographical surveying, including visual inspection and non-invasive tests, a geological survey of the local lithostratigraphy, and examination of notarial deeds and secondary sources to support findings about the building’s history as read from its ruins. An unmanned aerial vehicle was used to digitally record the parlous state of the architectural structure and karsten tubes were used to quantify the surface porosity of the limestone. The results are expressed from four perspectives. The anatomy of Casa Ippolito, as revealed in its ruins, provides a cross-section of its building history and shows two distinct phases in its construction. The tissue of Casa Ippolito—the building elements and materials—speaks of the knowledge of raw materials and their properties among the builders who worked on both phases. The architectural history of Casa Ippolito reveals how it supported its inhabitants’ wellbeing in terms of shelter, water and food. Finally, the ruins in their present state bring to the fore the site’s potential for cultural tourism. This case study aims to show that such ruins are not just geocultural remains of historical built fabric. They are open wounds in the built structure; they underpin the anatomy of the building and support insights into its former dynamics. Ruins offer an essay in material culture and building physics. Architectural ruins of masonry structures are anthropogenic discourse rendered in stone which facilitate not only the reconstruction of spaces but also places for human users; they are a statement on the wellbeing of humanity throughout history.
