The article presents a brief synthesis of the results deal with the study of ceramics Maikop-novosvobodnaya community using the method of a. a. Bobrinsky and use of the microscope with 12 times magnification. it sets out ideas about raw materials, methods of construction, surface treatment. especially emphasized the problem of the use by the ancient potters of rotary devices. For the first time about such vessels were noted in the work of a. a. Bobrinsky and r. M. Munchaev in 1966, for example, vessels with a flat bottom. at present a series of examples of traces deal with use of rotary devices has expanded. in the article by a. s. Kizilov shows the simulation of the vessel of the Maikop culture and fixation of the traces of its turn without a fixed axis of rotation and with a non-fixed environment of rotation. as a result, the actual doing of those and other traces that prove the use of Maikop potters rotary devices with a fixed axis of rotation in the manufacture of vessels not only flat, but round bottom too.

Purpose. To substantiate the efficiency of processing hematite raw materials at the Krivoy Rog Mining and Processing Plant of Oxidized Ores using the direct reduction technology itmk3®. Metodology. Analysis of the results of the itmk3® direct restoration technology developed by Kobe Steel Ltd., Japan and Hares Engineering GmbX, Austria, with a view to using it to process Krivbass hematite ores into granulated iron (so-called “nuggets”). Findings. The involvement in the production of hematite ores (oxidized quartzite) of Krivbass with high iron content, but with low magnetic properties for their processing into granular cast iron is grounded. Originality. The use of itmk3® direct reduction technology from Kobe Steel Ltd., Japan and Hares Engineering GmbH, Austria for the processing of Krivbass hematite ores into granular cast iron is justified for the first time. Practical value. The efficiency of the use of hematite ores (oxidized quartzite) has been substantiated, which can significantly reduce the costs in the mining cycle for the economical production of metallurgical products.

The author of the article discloses the prospects of development of the world feed production for aquaculture based on the analysis of key innovative technological and market trends. The author specifies that shortage, high cost, low ecological compatibility of traditional raw materials - fish flour - are among major limiting factors in the development of production of feeds for aquaculture. This fact, in turn, limits sustainable development of aquaculture both in Russia, and in the world in general. The article presents the overview of a current status of the world industry of feed production in aquaculture, where the regional situation is studied, as well. For the first time, there is given the outlook of innovative technologies in feed production based on the alternative sources of protein (on the example of projects of leading aquabiotechnological companies) which will determine industry’s objectives for the mid-term perspective.

The importance of magnesite for the EU economy and industry is very high, making the understanding of their genesis for the exploration for new deposits a priority for the raw materials scientific community. In this direction, the study of the magnesite-hosting ultramafic rocks can be proved very useful. For the present study, ultramafic rock samples were collected from the magnesite ore-hosting ophiolite of the Gerakini mining area (Chalkidiki, Greece) to investigate the consecutive alteration events of the rocks which led to the metallogenesis of the significant magnesite ores of the area. All samples were subjected to a series of analytical methods for the determination of their mineralogical and geochemical characteristics: optical microscopy, XRD, SEM, EMPA, ICP–MS/OES and CIPW normalization. The results of these analyses revealed that the ultramafic rocks of the area have not only all been subjected to serpentinization, but these rocks have also undergone carbonation, silification and clay alteration. The latter events are attributed to the circulation of CO2-rich fluids responsible for the formation of the magnesite ores and locally, the further alteration of the serpentinites into listvenites. The current mineralogy of these rocks was found to be linked to one or more alteration event that took place, thus a significant contribution to the metallo- and petrogenetic history of the Gerakini ophiolite has been made. Furthermore, for the first time in literature, Fe inclusions in olivines from Greece were reported.

Rumex species are traditionally known to cure constipation, pain, inflammation, ulcer and tumor. The biological potential of Rumex nepalens is lies in chemical diversity of its constituents. In the present study, UPLC-DAD-MS method was developed for the concurrent estimation of polyphenols in Rumex species ( R. nepalensis, R. hastatus and R. dentatus) and validated for linearity (r2 > 0.999), limit of quantification and detection, inter and intraday precession, stabilities and recovery. The developed method has also been employed for metabolomic analysis of Rumex species. Qualitative and quantitative variation of polyphenols was observed among the aerial and root parts of Rumex species with highest content of polyphenol detected in aerial part of R. nepalensis. The quantitative data based matrix and HCA plot represents the variation of metabolites among the samples. R. nepalensis being widely used in traditional practices, was incorporated in detail. A total of seven molecules were isolated and characterized among which three compounds viz. 3- O- methyl epicatechin, quercetin-3- O- β-D-glucuronide and β-sitosterol-3- O- β-D-glucoside were isolated for first time from this plant. Eighteen metabolites were profiled in R. nepalensis using UPLC-MS/MS technique. Current comprehensive metabolomics approach will surely help in understanding the chemical diversity, discriminations and quality control analysis of raw materials and furnished products of Rumex.

Purpose – Recent literature emphasizes the application of lean manufacturing practices to food processing industries in order to improve operational efficiency and productivity. Only a very limited number of studies have focused on the implementation of lean manufacturing practices within small and medium-sized enterprises (SMEs) operating in the food sector. The majority of these studies used the case study method and concentrated on individual lean manufacturing techniques geared towards resolving efficiency issues. This paper aims to analyze the status of the lean manufacturing practices and their benefits and barriers among European food processing SMEs. Design/methodology/approach – A structured questionnaire was developed to collect data. A total of 35 SMEs' representatives, mostly CEOs and operations managers, participated in the survey. The study investigated the role of two control variables in lean implementation: size of the company and country of origin. Findings – The findings show that lean manufacturing practice deployment in food processing SMEs is generally low and still evolving. However, some lean manufacturing practices are more prevalent than others; e.g. flow, pull and statistical process control are not widely used by the food processing SMEs, whereas total productive maintenance, employee involvement, and customer association are more widespread. The key barriers encountered by food SMEs in the implementation of lean manufacturing practices result from the special characteristics of the food sector, such as highly perishable products, complicated processing, extremely variable raw materials, recipes and unpredictable demand. In addition, lack of knowledge and resources makes it difficult for food processing SMEs to embark on the lean journey. Originality/value – The gap in the literature regarding the application of lean manufacturing in the food sector is identified and addressed in this study. The originality of this paper lies in analyzing the current status of the use of lean manufacturing practices among food SMEs in Europe and identifying potential barriers.
