We document the use of organic raw material in late Pleistocene eastern Beringia through the study of the site of Swan Point CZ4b, in central Alaska. CZ4b is attributed to the Dyuktai culture and dates to about 14,000 cal B.P. We interpret the occupation as a specialized workshop dedicated to the production and maintenance of organic-based tools following three lines of evidence: (1) limited on-site consumption of megafauna, (2) diversity of organic raw materials and techniques used in processing them, and (3) spatial demarcation of specialized activity areas. Specialized workshops are located in the vicinity of naturally occurring accumulations of mammoth bones in both western and eastern Beringia and suggest similarities in animal resource use across Beringia for the Dyuktai culture. Organic technology was a major portion of Dyuktai technology in eastern Beringia, and its lack of visibility in archaeological assemblages is probably due to taphonomic reasons. Changes in the availability of organic raw material throughout the Late Pleistocene offer some implications for the evolution of lithic technology and material culture.

The Picamoixons site is a rockshelter located in the province of Tarragona (NE Iberian Peninsula). It was object of two rescue campaigns during 1988 and 1993, which led to the recovery of a complete archaeological assemblage, including stone tools as well as faunal and portable art remains that date the occupation to the 14th to 11th millennium BP (calibrated). This study involves a petrographic characterisation of the stone-tool assemblage in order to establish: 1) the procurement areas, 2) the raw materials management strategies and 3) the mobility radius and territorial sizes of the hunter-gatherers groups that occupied the site. The method applied comprises in a multiscale analysis that includes systematic prospection, the petrographic characterisation of geological and archaeological samples, an analysis of the chert types represented in the knapping sequence, and the definition of the mobility axes and areas frequented according to lithic procurement.A petrographic analysis of the chert in the prospected area led to the definition of nine macroscopic varieties related to five types (Vilaplana, Morera, Maset, Vilella and Tossa cherts), related to Lower and Upper Muschelkalk (Triassic), Lutetian, Bartonian (Palaeocene) and Sannonian (Oligocene) deposits.The study of the knapping sequences indicates the main exploitation of Bartonian cherts (Tossa type), and the use of Lutetian cherts (Maset and Morera types) for configuring retouched tools. The exploitation of the remaining raw material types identified is considered sporadic and opportunistic.Defining the procurement areas enabled the mobility radius to be assessed as between 3 and 30 km, highlighting the importance of the fluvial basins as natural movement pathways. The results indicate that the main procurement territory was 16 km2 in area, associable with a forager radius. The most remote procurement distances suggest a maximum exploitation area of 260 km2, defining an intra-regional range. This range presents parallelisms with various contemporaneous hunter-gatherers groups in Western Europe, suggesting a progressive mobility reduction dynamic during the Late Pleistocene-Initial Holocene.

Technology studies have always been the most important focus of archaeology, as a science which analyzes human past through the study of material culture. To say that something is technological in archaeology, means to put the concept of technology in the centre of theoretical studies, and to study not only the form of the object, but also the entire sequence of technological factors, from raw material choice, mode of use, up to the reasons for abandonment. The concept of technology in anthropology and archaeology is based on the original meaning of the word ????? in ancient Greek, meaning the skill, i. e., to study how something is being done. Such a concept of technology as a skill or mode of doing something was for the first time outlined by the French anthropologist Marcel Mauss, whose starting point was that every technological statement was at the same time social or cultural statement and that technological choices have social foundations. Pierre Lemonnier further developed the anthropology of technology, focusing on the question of technological choices, as well as numerous other anthropologists. In archaeology, the most important contribution to the study of technology was the work of Andr? Leroi-Gourhan, who created the concept of cha?ne op?ratoire, as an analytical tool for studying the mode of creating, using and discarding an artefact, starting with raw material acquisition, mode of manufacture, final form, use (including caching, breaking and repairing) up to the final discarding. It is not only about reconstructing the algorithmic sequence of operations in creating one object, but it is a complex analysis of operational chain within one society which includes the analysis of technological choices. The analyses of technologies today include a variety of different approaches, most of them with emphasis on the cultural and social aspects of technology. The analysis of bone industry in the Early and Middle Neolithic in central Balkans (Starcevo culture), which included not only final objects, but also manufacture debris and semi-finished products, revealed a well developed industry, with a high level of technological knowledge on the properties of raw materials, skillful manufacture, well organized production, as well as possibility of a certain degree of specialization on the micro and macro level (within one settlement and within a group of settlements). Both raw material choices and manufacturing techniques, as well as the final forms, demonstrated a high standardization level. Also certain symbolic value was attributed to some raw materials, and there is a possibility that skill itself was valued. Further analyses of multiple technologies will help in reconstructing the organization of production, social and economic aspects in Neolithic societies, as well as the role of technology in everyday and ritual life.

An approach implemented in a higher school education system requires use of interactive forms in learning process. Using the example of organisation of laboratory and practical lessons "Methods of quality control with respect to raw materials and products of chemistry manufacture" the effectiveness of training discussions as an interactive form of learning while implementing a competency based approach was demonstrated. Analysis of natural magnetite, used as a raw material for production of iron by the pyrometallurgical method, was chosen as a subject of the discussion. Initially, students analyse State Standard (GOST) N 32517.1-2013 on their own. In class they analyse the Standard from the perspective of use of potentiometric titration instead of visual one under the supervision of instructors. They do modernization of technique for determining: correct a list of specimen used, solution strength, mass of magnetite sample, volume of a sample for titration; suggest a list of laboratory dishes and devices, make preliminary calculations and find out the calculation formula. In the course of discussion, the most preferable method of experiment is elaborated on and recorded. Upon completion a public discussion of the results is held. Each group analyses the obtained data, indicates the positive and negative sides of the suggested method for potentiometric determination of iron content in naturally occurring magnetite. Based on results of questionnaire survey having been held among students who took part in the pedagogic experiment, it was discovered that the proposed way of holding laboratory and practical lessons is more effective in comparison to the traditional one, while serving to unlock the students’ research potential. This way requires applying theoretical skills learned earlier to perform a particular research task. They also learn to work in a team, to sum up results of the common activity and hold responsibility for the results received. Moreover, public speaking is also an important point of learning process. The proposed methods of gaining skills for solution of training tasks facilitate development of intellectual, speaking and communicative students’ competences; they make future specialists more prepared for resolving real production issues.For citation:Sazhina O.P., Glazkova O.V., Shabarin A.A., Matyushkina Yu.I.

The traditional white-ware manufacturing industries in Bangladesh use clay as the prime raw material which is mostly imported from abroad. The main reasons are the lack of proper clay refining technolo gy in the country and in some part the unsuitable chemical and structural composition of the locally available naturally occurring clays. Moreover, particle size has also been identified as a major challenge in processing of naturally available clay. These two vital aspects affect plasticity and strength of clay during their processing. The composition and particle size of locally available clay were investigated using X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD) to reveal the potential of these clays for industrial purpose upon refining. XRF analysis showed presence of excess SiO2 content in the form of Silicate, Fe2O3 and TiO2; all of which pose a challenge in the refining process. Moreover the amount of Al2O3 in most of the compositions is also not up to the minimum level. Using the data based on statistics on particle sizes of raw materials of various origins, this experiment was aimed to reveal the composition and properties of locally available clay that can be projected for further refining to make suitable as raw material for whiteware industries.

This paper details the characterisation of four obsidian artefacts from the Mesolithic site of Livari Skiadi, one of only a handful of such pre-Neolithic sites on Crete. Elemental analysis using EDXRF sources the raw materials to Sta Nychia on Melos; in concert with other data, it can be suggested that this was the preferred Melian source for Late Pleistocene – Early Holocene populations. The Livari material represents the earliest Melian obsidian on Crete and by implication the first evidence of its inhabitants' connections to the Cycladic islands. When located within a broader review of Melian obsidian use in the Upper Palaeolithic – Mesolithic Aegean, it can be shown that the main consumers of these raw materials were island-based groups with immediate access to waterways that led to the Cyclades. It is suggested that distinctions between island and mainland toolkits (technical and raw material choices) may have been the product of seasonal, and environmental influences, rather than reflecting the products of different populations. Finally, certain datasets, including Livari, suggest the procurement of obsidian via intermediaries. These exchanges are viewed in avowedly social terms, with gift-giving a fundamental manner through which inter-group relations were created and maintained, whereby the circulation of obsidian can be viewed as one of those mechanisms through which Mesolithic Aegean cultural traditions came to be produced and reproduced.

AbstractThe study of raw materials is an essential step in lithic analysis, regardless of the age, provenance, and technology of the assemblages. As in many other contexts of the Paleolithic, researchers of the Middle Stone Age (MSA) in southern Africa have often focused their attention on fine-grained, non-local rock types, such as silcrete. Here, I spotlight raw materials considered to be of lower suitability for knapping and frequently acquired from local sources. Due to their coarse-grained nature, artifacts from rock types such as calcrete, sandstone, and quartzite might show attributes that are different from finer-grained materials. Some of these knapped stones even constitute the substrate of the sites they are from, at times resulting in their neglect or not being recognized as anthropogenic artifacts. Knapped vein quartz features sharp and durable edges, but its complicated fracture mechanics hamper comparative analysis and provide methodological challenges. In this study, raw materials from different transport distances and with different presumed qualities are compared in terms of their roles in MSA lithic technology and settlement patterns. In the first step, the article focuses on the open-air special-purpose camp of Hoedjiespunt 1 (HDP1, Western Cape) and the rockshelter residential site of Sibudu (KwaZulu-Natal), especially on assemblages dated between ~ 130–100 and ~ 58 ka. Subsequently, I review relevant materials for the southern African MSA. At HDP1 and Sibudu, local raw materials of lower knapping suitability assume several roles, from the “staple” material for all manufacturing stages to special-purpose and “add-on” functions. In the broader southern African region, MSA knappers also used these rock types in a flexible manner with gradual differences but also similarities to their use of finer-grained raw material. These differences depend on a complex interaction of raw material availability, differential site use, and the position of the localities in the settlement system.

Introduction. The objective of the research is to study the effect of the complex activation of the alumina raw material on the rheological properties of the ceramic mass. In addition, the authors investigate solutions for the application of optimal coagulation structures based on loams and ash together with plastic certificates.Materials and methods. The authors used the local forest like reserves of clay loams at the BashKarasu, ash fields of the Bishkek Central Heating Centre (BTEC) and plasticizer (sodium naphthenate obtained from alkaline chemical production wastes) as fibrous materials. Moreover, the authors defined technological properties of raw materials within standard laboratory methodology in accordance with current GOSTs.Results. The researchers tested plastic durability on variously prepared masses for the choice of optimal structures. The paper demonstrated the plastic durability of complexly activated compounds comparing with non-activated and mechanically activated compounds. The sensitivity coefficient increased the amount of clay loams by mechanically and complexly activated, which predetermined the possibility of intensifying the process of drying samples based on complexly activated masses.Discussion and conclusions. However, mechanical activation of clay material reduces the period of relaxation and increases the elasticity coefficient of ceramic masses by 1.8–3.4 times, meanwhile decreases elasticity, viscosity and the conventional power during molding, which generally worsens the molding properties of the masses. Сomplex activation of ash-clay material decreases the period of relaxation and provides an increase in elasticity, plasticity of ceramic masses by 46–47%, reduction in viscosity by 1.5–2 times, conventional power on molding by 37–122% in comparison with MA clay loams. Ceramic masses based on spacecraft alumina raw materials belong to the SMT with improved rheological properties; products based on them pass through the mouthpiece for 5–7 seconds.

Organic materials that are generally used as raw material for organic fertilizer granules (POG) is a natural organic material that has been degrade, smooth and dry. One of the main raw materials are always used with a very high percentage of usage, is manure. Manure potential in Indonesia is very high, amounting to 113.6 million tons per year, or 64.7 million tons per year to the island of Java. From this amount, it will be generated numbers POG production potential of 17.5 million tons per year (total Indonesia) or 9.9 million tons per year for the island of Java. While the realistic POG production predictions figures made from raw manure is 2.5 million tons annually, a figure that has been unable to meet the number requirement of POG greater than 4 million tons per year. Therefore, in producing POG, it should be to maximize the using of the potential of other organic materials so that the use of manure can be saved. With the use of a small amount of manure (maximum 30% for cow manure), it would be useful also to avoid the production of POG with high Fe content.keywods: organic material, manure, granule organic fertilizer

Health indicators of the population depend significantly on the food quality and nutritional value. Simple carbohydrates excess of and lack of protein, dietary fiber, vitamins, minerals, antioxidants and other physiologically active substances increase the risk of socially significant disease progress. The development and production of mass-consumed products with high nutritional and biological value, including affordable non-traditional raw materials use, are promising areas of the food industry development aimed at improving the nutritional status of the population. The article presents the research results on the developed Noodle products recipes from non-traditional raw materials that meet modern healthy nutrition requirements, intended for dietary treatment and dietary prevention of people with overweight / obesity. The research aimed at expanding the range of macaroni products with these characteristics. As the main raw material, a man selected whole-wheat flour – new spelt flour, and as additional raw materials – buckwheat flour, broccoli and celery powders. The researchers found that the introduction of macaroni products from buckwheat spelt, broccoli and celery powders into the recipe had a multidirectional effect, reducing or increasing various indicators of its nutritional value. The changes range did not affect the overall characteristics. The satisfaction degree of the average daily need for food substances and energy when consuming a portion of 100 g for each sample of developed Noodle products allows them to be classified as functional products that are protein and dietary fiber sources, according to the requirements of the TR CU 022/2011.
