ABSTRACTBòbila Madurell-Can Gambús is the most emblematic Neolithic cemetery in the northeastern Iberian peninsula, with a total of 179 documented pit burials. Artifacts made of exogenous raw materials, such as honey flint (southeastern France), jadeite, amphibolite, eclogite and nephrite (Alps and the Pyrenees), variscite (coast of northeastern Iberia), and even obsidian (Sardinia), have been found in the burials. The presence of these raw materials is not exclusive to this necropolis, but they have also been documented in many of the graves of this region during this period. The literature has singled out this funerary practice as the Pit Burials cultural horizon. However, until now the chronology of this funerary practice has not been fully defined, so it was difficult to explain the development of the chronology and the networks through which the materials reached northeast Iberia. New, unpublished radiocarbon (14C) dates of Bòbila Madurell-Can Gambús are presented, as well as the results of different statistical analyses and Bayesian modeling that specify its chronology. Through the contribution of new data on the chronology of Bòbila Madurell-Can Gambús new clues regarding the temporal dynamics of pit burials and the raw materials exchange networks associated with them are presented.

Ne Iberian Peninsula

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.

This paper is divided into three sections. The first section describes the historiographic evolution of the study of prehistoric lithic raw materials in the Basque Crossroads (in the north of the Iberian Peninsula) during the last three decades. The second section explains the currently available information about geological outcrops of flint in the eastern end of the Cantabrian Mountain range (the Basque-Cantabrian Basin), the upper Ebro valley and both sides of the western Pyrenees, in the central part of the northern Iberian Peninsula, as that was the main raw material used by hunter-gatherer groups in the Middle and Upper Palaeolithic. Finally, the last section describes the way in which progress in both aspects of research have enabled the introduction of new concepts and perspectives in the reconstruction of the social and economic dynamics of Palaeolithic hunter-gatherers. This has given rise to an innovative methodology that is able to address and solve important issues, particularly regarding mobility and territoriality patterns of those human groups, allowing the proposal of mobility and territoriality models that, while they will not match exactly the systems used by Upper Palaeolithic communities, represent significant progress in understanding the social and economic dynamics of hunter-gatherer groups.

Historical Times

The basins of the Manzanares and Jarama rivers have been connected to human activity since the early Palaeolithic. At the boundary between these rivers the abundance of flint has given place to exploitation and mining activities even in historical times. In recent years, projects related to urban expansion in the southeast of Madrid have brought to light various Palaeolithic deposits associated with workshops and tool production. These sites do not have evidence of river pebbles of quartzite, quartz or sandstone in the immediate environment that could have been used as hammerstones, meaning that hammerstones in these raw materials had to be transported and introduced into the sites from large distances. Given this situation, attention was paid to flint elements that show clear signs of being used as hammerstones. The aim of this study is to test the effectiveness of flint as hammerstone, testing whether the use of this raw material is indifferent to other rock types or if you have limitations or advantages in this regard. An experimental protocol was developed, allowing to observe specific knapping behaviours and justifying them in the archaeological and technological context in which they are located.

Material Transportation

Distances of raw material transportation reflect how hominid groups gather and exchange information. Early hominids moved raw materials short distances, suggesting a home range size, social complexity and communication system similar to primates in equivalent environments. After about 1.0 million years ago there was a large increase in raw material transfer distances, possibly a result of the emergence of the ability to pool information by using a protolanguage. Another increase in raw material transfer occurred during the late Middle Stone Age in Africa (after about 130,000 years ago), suggesting the operation of exchange networks. Exchange networks require a communication system with syntax, the use of symbols in social contexts and the ability to express displacement, which are the features of human language. Taking the Neanderthals as a case study, biological evidence and the results of computer simulations of the evolution of language, I argue for a gradual rather than catastrophic emergence of language coinciding with the first evidence of exchange networks.

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.

The book under review is a concise but fairly in-depth study of the prospects for export diversification from the Less Developed Countries (henceforth labeled as LDCs) particularly to Developed Countries (henceforth labeled as OCs). Given the multiple problems faced by the LOCs in exporting to the OCs - protectionist policies with regards to manufactured exports, volatility of prices obtained for raw material exports, etc. - the study analyses the potential for following an intermediate route. The important issues in the export of semi -processed and wholly processed raw materials are discussed. 111ese issues range from the problems and potentials for the location of processing facilities in the LOCs to the formulation of appropriate policies to encourage an export of processed goods rather than raw materials. Such policies will be useful both in solving the balance of-payments problems of the LDCs and in attaining the goal of the Lima Declaration and Plan of Action on Industrial Development and Co-operation, that called for 2S percent of world industrial production to be located in the LOCs by the year 2000.

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.
