In the farms of the north-eastern slope of the Greater Caucasus wood raw material obtained from intermediate felling, is not fully utilized and is not effective, due to the organizational and technical difficulties of farms. In addressing these issues in 8 directions of the region with a length of 40-50 km 14 intermediate assembly points were organized, which are intended for the collection and temporary storage of wood raw material harvested within a radius of 15-20 km of the forest. Need to establish assembly points is due to the complexity of relief items and the possibility of year-round use of the main roads of regional importance. To ensure uninterrupted timber industry and in full at the assembly point accumulated wood raw material is partially sorted. Processing of harvested wood raw material is planned for timber industry, located near the central region of the main road in the territory of Cuba town. Establishment in the area of the complex is considered justified, since the resource base in the coming years for intermediate, and later for the main use will be more than 100 thousand hectares of forests in the region. In the proposed area for the industrial complex for processing of raw wood there are all the technical and economic prerequisites. Accumulated in the assembly points wood raw material to the point of processing is transported using self-loading lumber carriers of up to 8 meters length, which is associated with a complex terrain conditions and road network in the region. This complex is planned to organize the following process areas: sawmills, parquet and packaging, small-chip technology, processing of technical greenery. In organizing the production sites size and quality characteristics and volumes of each category of harvested wood raw materials are taking into account, as well as the need for forest products in the region and the country as a whole. In the processes it is envisaged to use the most advanced modular processing of wood with the release of standard lumber, wood workpieces of different products, pulp chips, wood greens and products of its processing.

The influence of the degree of grinding of the particles of growing raw materials during electric discharge extraction on the quality of the obtained extracts was studied. Each discharge during electro-discharge extraction contributes to the grinding of a part of the raw material, which is confirmed by granulometric analysis. The particle size of the raw material should be controlled, since excessive grinding of the extracts results in cloudy, difficult to clarify and poorly filtered. The design of the extraction chamber is proposed, in which the grounded electrode is made in the form of a perforated plate, called a false bottom, with the optimal size of the holes and their density, which eliminates the over-grinding of the raw material particles, which leads to the production of turbid and difficult-to-filter extracts. Since the extraction of raw materials is carried out at a certain ratio of solid-liquid phases, the volume of the chamber from the sieve to the bottom does not significantly affect the kinetics of the extraction process itself, since it is intended for collecting the smallest particles of processed raw materials, the mass of which does not exceed 15-16% of the loaded mass of raw materials. The device of the extraction chamber, due to the high turbulence and intensive mixing of the suspension under the action of cavitation and shock waves initiated by the discharge in the liquid, allows you to remove small particles of raw materials less than 1 mm in size from the working area of the chamber. The results of the study show that the extraction of target components from various raw materials using a chamber with a false bottom can significantly reduce the content of the smallest particles of raw materials in the extract. It facilitates the filtration of the extract, reduces the filtration time, significantly reduces the likelihood of turbidity of the solution due to suspension, which improves the quality of the extract. Experimental studies of the developed electric discharge chamber with a false bottom, conducted with various types of plant raw materials, confirm the effectiveness of extraction in the chamber of the proposed design.

Eri silk is one of the wild silk varieties which are mainly available in the north-eastern areas of India. It exhibits goodmechanical and thermal resistance properties. In this concern, the present study focused to develop a bi-layer knittedstructure made from Eri silk yarn as one side(next to skin) and on another side bamboo yarn knitted fabric. Similarly,Tencel knitted fabric was used instead of bamboo. Twenty-four bi-layer knitted fabrics were developed and thenanalysed for its thermal comfort property. The air permeability, and wick-ability were found to be higher and the thermalresistance was found to be higher for bi-layer plated interlocked knitted fabric made out of Eri silk compared to bambooand Tencel.

Nowadays, in Colombia, specifically in the north-eastern, in Santander region, the process of mixing the ceramic paste used to manufacture masonry products for construction (H- 10 bricks, tiles, roof tiles, etc.) is done manually. For this reason, approximately 70% of the companies do not possess the technological tools which facilitate the prediction of the behavior of the raw material (clay). The main objective of this research is to formulate mixtures at a laboratory-level in order to verify the physical properties of ceramic raw materials used by a company which was takenas a sample. The research development was carried out through the execution of tests and laboratory analysis, taking into account the formulation of mixtures with the help of Statgraphics Centurion XV software in order to obtain combinations of raw materials according to the requirements of the current standard techniques. The results demonstrate the importance of using statistical programs for the improvement of systems and processes, predicting the behavior of raw materials as well as conducting pilot tests, taking into account the laboratory analyses in the ceramic industry. Conclusions: The results show that the mixture combinations obtained have the necessary parameters to meet the current standards such as resistance and absorption, which will optimize the economic and physical resources of the company, as well as the quality of the final product.

The study of large chert blades documented in funerary contexts from the Late Neolithic to the Early Bronze Age in the north-eastern part of Iberia has been addressed in recent works by the authors, in which 49 burial sites have been registered with more than 200 large chert blades. In this paper the recent data obtained from the study of seven archaeological sites located in the region of the Penedès (southwest of Barcelona) is presented.The macroscopic characterization of the knapped stone industries shows their great variety regarding the origin of the siliceous raw material, often coming from outside the analysed region. In some cases their macroscopic features link them to Apt-Forcalquier chert (Haut Provence, France), which was widely distributed in the form of large blades during these phases of Late Catalan prehistory.The absence of evidence of the chaîne opératoire production of this type of foreign chert in the lithic assemblages in Catalonia lead to the supposition that the dispersion of the blades was done as trade items, and only in a few cases were highly complex technological tools of this kind of raw material distributed (e.g., daggers). Use-wear analysis reveals that these blades were not merely luxury items in grave goods. Far from this idea, they have to be considered as functional, even multifunctional, items. All the same, it is thought that they must have had an important value because they moved from the domestic sphere to the graves. In fact, the pieces that usually remain are not small fragments, but whole or almost whole, large blades that normally remain effective.

In the course of the literature analysis on the introduction of PinusrigidaMill.Conclusions that indicate the feasibility of continuing research to optimize the structure of the forest seed base for the further use of the species in the north-eastern forest-steppe of Ukraine has been made. Specifically, it has been found that the results of experimental studies on the biological and ecological properties of P. rigida in habitat and Polesie regions characterize it as a fast growing and highly productive plant that has adapted in this region to a wide range of growth conditions, which may induce growing the species under the conditions of the northeastern forest-steppe of Ukraine for further use in protective forest plantations; the effects of global climate change are becoming more pronounced in Ukraine, so given the problems showed, it is worth paying attention to the species under study, which lies in its ability to stool shoot. The project of development of P. rigida genetic-selected objects has been proposed, which stated the following: optimization of the structure of the forest-seed base of the researched species in the north-eastern Forest-Steppe of Ukraine, the proposed recommendations will allow to accelerate the transition of seed production in the region to genetic-selection grounds for utilization in protective forest plantations; given the much higher wind resistance of the species under study compared to Pinus sylvestrisL., it should be introduced as an accompanying breed of up to 20 % in pine forests to increase productivity and wind resistance of plantations; we can produce 278 trees during the period of seedsproduction according to our recommendations to create 1.0 ha P. rigida plantation. About 30 kg of cones or 900 g of seeds can be harvested from one tree. Accordingly, given the germination of seeds of P. rigida, we will be able to get about 35806 seedlings from one tree. Due to the high regenerative ability of the species (stoolshoot), it should be used in the creation of protective forest plantations. Introduction of the species will reduce the cost of supplementation.

On June 7, 2018, a sub-mesoscale anticyclonic eddy induced by the wind (north-east) was registered on the shelf in the area of the city of Gelendzhik. With the help of field multidisciplinary expedition ship surveys, it was shown that this eddy exists in the layer above the seasonal thermocline. At the periphery of the eddy weak variability of hydrochemical parameters and quantitative indicators of phytoplankton were recorded. The result of the formation of such eddy structure was a shift in the structure of phytoplankton – the annual observed coccolithophores bloom was not registered.
