Presentamos un conjunto lítico recuperado con ocasión de la actividad arqueológica preventiva llevada a cabo en el solar donde se ubicó la fábrica de Conservas Garavilla. Nuestro análisis de las distintas estrategias y métodos de talla de los soportes líticos, sin olvidar la importancia de la secuencia operativa completa, desde la adquisición o selección de las materias primas, con estudio litológico, primeros gestos técnicos, reducción de volúmenes y configuración final de los productos arqueológicos, nos permite adscribir el conjunto al modo técnico 3. Todo ello será valorado en su contexto geológico y geomorfológico, lo que nos ayudará a situar al grupo de cazadores-recolectores protagonista en su medio natural, como integrantes de un proceso histórico vinculado al modo técnico 3.AbstractWe present a lithic ensemble recovered on the occasion of the preventive archaeological activity carried out at the site where the factory of Conservas Garavilla stood. Our research into the different strategies and methods to produce lithic stone tools, without forgetting the importance of the entire operational sequence, from the acquisition or selection of raw materials, with lithologic study, first technical gestures and reduction of volume, to the final configuration of archaeological products, enables us to assign the ensemble to technological mode 3. All this will be considered in its geological and geomorphological context, which will help us to locate the hunter-gatherers protagonist group in its natural environment as part of a historical process connected to what we know as technological mode 3.

Статья продолжает серию публикаций по результатам технико-технологического анализа керамики памятников раннего железного века Томского Приобья, относящихся к шеломокской культуре и к томскому варианту кулайской культурно-исторической общности. Для анализа были взяты фрагменты керамики из могильника Шеломок I, поселений Кижирово и Самусь II. Результаты анализов показали, как сходство, так и отличия в выборе исходного сырья и подготовки формовочных масс. Например, если для поселения Шеломок II – базового памятника шеломокской культуры, характерна примесь дресвы из гранита с белыми и прозрачными включениями кварца (Плетнёва, Степанова, 2018), то в формовочных массах керамики из могильника добавляли гранит с красными (розовыми) включениями кварца. Памятники эти расположены рядом, на расстоянии 500 м друг от друга, то есть природная среда была одинаковой. Датировка поселения Шеломок II укладывается в пределы V–III вв. до н. э., а могильника Шеломок I – IV–III вв. до н. э., что свидетельствует об их синхронном существовании. Предметы из могильника находят ближайшие аналогии в материалах шеломокской культуры. Сравнение предметного ряда изделий из бронзы, кости и рога свидетельствует о контактах оставившего его населения с тагарцами Ачинско-Мариинской лесостепи, а также, возможно, с населением большереченской культуры, по мнению И. Ж. Рагимхановой и возможно, по мнению Л. М. Плетневой, материалы могильника отражают сложные культурные процессы раннего железного века, происходившие в Томском Приобье и фиксируют приход населения из Ачинско-Мариинского района тагарской культуры.This paper continues a series of publications that report the results oftechnical and technological analysis of ceramics from the Early Iron Age monuments of the Tomsk Ob Region, which are attributed to Shelomok and Tomsk variants of the Kulay cultural and historical community. Fragments of ceramics have been taken for analysis from the Shelomok I burial ground, Kizhirovo and Samus II settlements. The results of analysis demonstrate both similarities and differences in the choice of raw materials and the preparation of molding compounds. For example, the addition of granite gruss with white and transparent quartz inclusions to the pottery paste was typical of Shelomok II settlement (Pletneva, Stepanova, 2018), while the pottery paste from the burial ground included granite with red (pink) quartz inclusions. These monuments are located nearby, at a distance of 500 m away from each other, in the same natural environment. Perhaps, the materials of the burial ground reflect the complex cultural processes of the early Iron Age that took place in the Tomsk Ob region and record the arrival of the population from the Achinsk-Mariinsky district of tagar culture.

The article analyzes the ceramics of the Timber culture, recovered from a kurgan cemetery near the village of Tverdilovo (excavated in 2017 in the Western Orenburg region). Under embankment of kurgan 1, 30 vessels were found in 21 burials, made in a narrow chronological interval. When considering these vessels according to one methodological system, which includes morphological and technical and technological analysis, the peculiarities of the production of pottery were highlighted both for a single group of the population and for the region as a whole. The analysis of the technological traditions of ceramics production from the Tverditovo kurgan cemetery shows that the population that left these ceramics was not homogeneous. There are two different traditions even at the stage of selection of plastic soft raw materials: one of them used silty clay for making dishes, the other applied natural clay. So, it is difficult to explain an isolated case of using sludge and low-grade ferrum clay. Using comparative analysis we can assume that the nearest burial monument according to its ceramics products is the Bogolubovskiy kurgan cemetery where we also can find silty and natural clay and the receipt of molding mass as “clay+ chamotte+ organic materials”. Pottery traditions of the population that left the presented vessels were heterogeneous, which is recorded both in terms of morphological and technological characteristics. A similar picture is typical for other settlement and burial sites in the Orenburg Cis-Urals. The monument was dominated by the pottery traditions of the Timber culture with a slight influence of the Alakul elements.

AbstractMicrobiological control is of crucial importance in the pharmaceutical industry regarding the possible bacterial contamination of the environment, water, raw materials and finished products. Molecular identification of bacterial contaminants based on DNA sequencing of the hypervariable 16SrRNA gene has been introduced recently. The aim of this study is to investigate the suitability of gene sequencing using our selection of PCR primers and conditions for rapid and accurate bacterial identification in pharmaceutical industry quality control.DNA was extracted from overnight incubated colonies from 10 bacterial ATCC strains, which are common contaminants in the pharmaceutical industry. A region of bacterial 16SrRNA gene was analyzed by bidirectional DNA sequencing. Bacterial identification based on partial sequencing of the 16SrRNA gene is the appropriate method that could be used in the pharmaceutical industry after adequate validations. We have successfully identified all tested bacteria with more than 99 % similarity to the already published sequences.

With the purpose of enabling the analysis by digital methods of particles of multisource pharmaceutical raw materials, this study analyzed different crystal habits of ampicillin particles, by grouping the external shapes obtained from 3 different solvents (acetonitrile, ethanol, and methanol), thereby reducing the number of descriptors necessary to adequately represent each shape. For this purpose, a selection of morphological descriptors was used including: circularity, roughness, roundness, compactness, aspect ratio, effective diameter, solidity, convexity, fractal dimension, and 10 Complex Fourier descriptors. These measures cover highly diverse morphological properties and define the crystal habit of a particle. Principal Component Analysis (PCA) and the Cluster Analysis (CA) were the grouping techniques used, which demonstrated the possibility of using between 2 and 4 descriptors instead of the 18 proposed initially.

Amylase is an amylolytic enzyme used in food industry which is generally produced by Aspergillus spp. under solid state fermentation. The present study is concerned with the isolation, screening and selection of suitable strains of Aspergillus spp. and optimization of cultural conditions for the biosynthesis of amylase. Rice and wheat brans were used as substrates which are readily available inexpensive raw materials for amylase production. From 85 samples of rice and wheat grains, 55 colonies obtained on potato dextrose agar (PDA) were suspected to be Aspergillus oryzae and only 35 colonies possessed the morphological characteristics similar to that of A. oryzae indicating the isolates were most likely the strains of A. oryzae. Of all the fungal isolates of Aspergillus spps., Asp.31 gave maximum production of amylase (720.782 IUgds-1) in solid state fermentation media. This strain was selected as a parental strain for optimization for cultural conditions. The obtained data were analyzed using SPSS- 11.5 program. Of all the substrates (rice bran, wheat bran and their mixture), rice bran was the best for producing amylase of highest activity 611.614 IUgds-1.The highest enzyme activity of 698.749 IUgds-1 was observed at 50% initial moisture level of the substrate. The optimum temperature was 25°C for producing the crude amylase enzyme with amylase activity of 577.757 IUgds-1.

Currently, many of the key archeology issues, including the questions of origin, relationships, migration and trade routes, sources of raw materials, technological methods in the processing of metals, etc., are difficult to solve by ar- cheology means alone. Progress in the field of instrumental technique regarding the advent of the latest-generation devices allows not only to perform elemental analysis of samples but also to measure with high accuracy different isotopes, which are often certain markers that characterize some components of the natural environment, provinces of habitation, diet and other important aspects of the ancient people’s habitat.

The paper presents the results of a techno-morphological analysis of items made of antler obtained as a result of the collections from the 1960s-1990s from the site near the village of Michnievičy Smorgon District of the Grodno Region (north-western Belarus). Currently, more than 100 artifacts are known from this site, as well as a large number of fauna residues with no visible traces of processing. Radiocarbon dating was obtained for some categories of products, which link them to 9-2 thousand BC. The largest part of the collection refers to the period of the Mesolithic - Neolithic. At the first stage of work, the most expressive and numerous group of artifacts made of horn (24 exemplars), stored in the fonds of the Institute of History of the National Academy of Sciences of Belarus, was selected for a techno-morphological analysis. The degree of preservation of the external surface of objects is relatively good, which made it possible to analyze macro-traces related to the technology of manufacturing various categories of products, on the basis of which a process flow was proposed - from the selection of raw materials to the finished product. The analysis of the technological traces recorded on the products allowed us to highlight the differences in the manufacturing processes of the oldest tools. In addition, on the basis of the macro signs of utilitarian wear, preliminary observations on the functional using of objects were obtained. According to technological and morphological features, the whole of the analyzed material was divided into conditional categories of instruments with a selected heel and without it. The presence or absence of this element, apparently, influenced the method of using objects in various household situations.

The aim of the work was to present the issue of eco-efficiency, based on the PN-EN ISO 14045:2012 standard in relation to the production of fatty acid methyl esters (FAME). The ecoefficiency analysis takes into account economic and environmental aspects in the improvement of products and processes / technologies. Eco-efficiency considers the product and technology throughout the life cycle, from the construction phase, through use to decommissioning. The impact on the natural environment is assessed on the basis of: consumption of energy, materials, dust and gas emissions, waste and sewage. Total costs include: production costs, raw material costs, costs during the use phase including maintenance, repair and operating costs, product disposal or recycling. The eco-efficiency analysis is helpful in making decisions regarding the selection of a new product or designing a new technology, and enables the selection of the variant that is the most economical and has the least possible impact on the natural environment. These issues are particularly important in the case of biofuels. The rapid growth of their production and the European Union’s policy, which aims to increase the share of energy from renewable sources, cause concerns of many experts regarding the threats related to the production of biofuels, both for the environment and food security. In particular, efforts are made to minimize the amount of waste and residues by implementing the idea of a circular economy. This approach promotes the development of new technologies that are more environmentally friendly. Due to the regulations set out in the RED and RED II Directives, there is a chance that the biofuels will have a less negative impact on the environment. This results from the obligation to certify compliance with the sustainability criteria, which is carried out by voluntary systems recognized by the European Commission, such as the KZR INiG System.
