The article presents the analysis of the development of commercial objects in the North-Kuril zone of the Far Eastern fisheries basin for a ten-year period. The resource potential of this zone was found to consist of 11 objects for which the total allowable catches were established (TAC objects) and of 4 objects, the extraction of which is carried out within the recommended volumes (non-TAC objects). The main objects of production in the North-Kuril zone were pollock, Commander squid and terpug, the production volumes of each species, in the total catch of all objects, amounted to 48, 26 and 13%, respectively. The production volumes of the rest commercial objects amounted to a total of about 13%. An analysis of the dynamics of changes in the TACs was carried out for each test fishing object. A decrease of catch volumes in 2019, compared to 2010, was observed in three objects: terpugs, halibut and macrurus. For these objects during the period under review there was found a decrease in TAC volumes. Analysis of the development of the objects under study during the period 2010-2019 showed that crabs, scallops and pollock in the studied time interval had consistently high catch volumes and a high degree of development. The average rate of development of these objects was about 90% or more. The remaining 8 fishing objects were under-developed annually. The average degree of development of Far Eastern flounder, Commander squid, terpug, cod, sea bass was about 55-75%. The lowest average rate of development (less than 50%) was observed in halibut, pinchback and macrurus. It has been inferred that it is necessary to conduct further studies of fishing activities to develop the resource potential for subsequent modeling and optimization of fishing processes

Different Content

The paper presents data on the study of the content of carotenoids in plant fruits of different Sorbus species and varieties when introduced in the Komi Republic. As a result of a biochemical analysis, the accumulation of various amounts of carotenoids has been revealed: from 2,6 to 43 mg/%, depending on the species, sample and variety. The author compared the content of this group of substances in raw materials of plants introduced in the Komi Republic with the ones growing in other regions of Russia (Republic of Bashkortostan, Republic of Mordovia, Saratov, Penza, Moscow Region and others). It has been shown that under northern conditions in rowan fruits the value of the total carotenoids prevails in representatives of the Sorbus section with an East Asian range ( S. pohuashanensis , S. discolor , S. amurensis ), except the Far Eastern species S. sambucifolia . A different content of carotenoids in the plant fruits of S. aucuparia samples has been established: the maximum is in the sample from Yoshkar-Ola, which is 3-5 times higher than that in S. aucuparia from the Komi Republic. The content of this group of substances in the rowan fruits of the three studied varieties (Businka, Rubinovaya and Sorbinka) has been determined; their predominance in the Sorbinka variety has been shown. The study of the biochemical composition of plant raw materials of mountain ash species and varieties with the highest content of carotenoids when introduced in the North should be continued in order to further assess its qualitative composition and to develop recommendations for its use as a medicinal product, as well as a source of functional ingredients for pharmaceutical and food industries.

Abstract The Yakataga Glacier occupies a steep-walled valley in the Robinson Mountains on the north coast of the Gulf of Alaska. The main trunk of the glacier descends from 1130 to 150 m. in a distance of 21 km. A rock fall at the head of the glacier formed a moraine of distinctive shape which advanced at an average rate of 114 m./yr. from 1938 to 1954. The surface velocity of the glacier at fifteen stations below the firn line was calculated from the displacement of the rock-fall moraine and other less conspicuous features that are shown in two sets of vertical aerial photographs, taken in 1948 and 1954. For this time interval the average surface velocity along the medial line of the glacier ranged from a maximum of about 90 m./yr. at a station 14 km. above the terminus to zero at a station 2.3 km. above the terminus. The technique of photogrammetric measurement of surface velocity by using natural features on the surface of a glacier has wide application in Alaska, where many glaciers have been rephotographed from the air after intervals of a few years to as many as thirty years.

The authors consider propulsive potential of the ports of the eastern section of the Northern Sea Route (NSR) and indicate the influence of the NSR on increasing the efficiency of the key zones formation for the development of the Far Eastern Arctic. They base the work methodology on the theory of cumulative growth, in which the ideas of the “growth poles” formation occupy a decisive position. The authors use the grouping methods, logical and comparative analysis. The Rosstat data serves as an information base of the study. It is shown that the state’s activity on the development of the NSR stimulates the development of the North Yakutsk and Chukotka support zones, enhancing the transport and raw materials specialization of the Eastern Arctic as a whole. At the same time, the authorities proceed from the assumption that the development of ports should reduce the costs of trade, increase employment, and have a multiplier effect both on the port system itself and on the sectors of the region interacting with it. The paper substantiates that in the Far Eastern Arctic, the traditional view of ports as the most important infrastructure assets, which are the business and economic center of territorial development, is insufficient for the recognition of transport infrastructure as a propulsion industry. The propulsive effect of the port economy is low and is mainly of an induced nature, when capacities for processing products are created in the port areas, or when the transport infrastructure stimulates the emergence of transport-intensive extractive industries, which is provided in the western part of the NSR. For the development of the North Yakutsk and Chukotka Arctic support zones, the transport infrastructure will be a backbone project that “connects” these regions in an economically sustainable spatial formation — the Far Eastern Arctic. Transport is a necessary but insufficient condition for the emergence and accelerated development of local “growth poles” in the Eastern Arctic.

At production of stainless steel expensive alloying elements, containing nickel, are used. To decrease the steel cost, substitution of nickel during steel alloying process by its oxides is an actual task. Results of analysis of thermodynamic and experimental studies of nickel reducing from its oxide presented, as well as methods of nickel oxide obtaining at manganese bearing complex raw materials enrichment and practice of its application during steel alloying. Technology of comprehensive processing of complex manganese-containing raw materials considered, including leaching and selective extraction out of the solution valuable components: manganese, nickel, iron, cobalt and copper. Based on theoretical and experiment studies, a possibility of substitution of metal nickel by concentrates, obtained as a result of hydrometallurgical enrichment, was confirmed. Optimal technological parameters, ensuring high degree of nickel recovery out of the initial raw materials were determined. It was established, that for direct steel alloying it is reasonable to add into the charge pellets, consisting of nickel concentrate and coke fines, that enables to reach the through nickel recovery at a level of 90%. The proposed method of alloying steel by nickel gives a possibility to decrease considerably steel cost at the expense of application of nickel concentrate, obtained out of tails of hydrometallurgical enrichment of manganese-bearing raw materials, which is much cheaper comparing with the metal nickel.

AbstractContact networks provide insights on disease spread due to the duration of close proximity interactions. For systems governed by consensus dynamics, network structure is key to optimising the spread of information. For disease spread over contact networks, the structure would be expected to be similarly influential. However, metrics that are essentially agnostic to the network’s structure, such as weighted degree (strength) centrality and its variants, perform near-optimally in selecting effective spreaders. These degree-based metrics outperform eigenvector centrality, despite disease spread over a network being a random walk process. This paper improves eigenvector-based spreader selection by introducing the non-linear relationship between contact time and the probability of disease transmission into the assessment of network dynamics. This approximation of disease spread dynamics is achieved by altering the Laplacian matrix, which in turn highlights why nodes with a high degree are such influential disease spreaders. From this approach, a trichotomy emerges on the definition of an effective spreader where, for susceptible-infected simulations, eigenvector-based selections can either optimise the initial rate of infection, the average rate of infection, or produce the fastest time to full infection of the network. Simulated and real-world human contact networks are examined, with insights also drawn on the effective adaptation of ant colony contact networks to reduce pathogen spread and protect the queen ant.

Abstract Knowledge of the stratigraphic development of pre-Carboniferous strata in the subsurface of the Netherlands is very limited, leaving the lithostratigraphic nomenclature for this time interval informal. In two wells from the southwestern Netherlands, Silurian strata have repeatedly been reported, suggesting that these are the oldest ever recovered in the Netherlands. The hypothesised presence of Silurian-aged strata has not been tested by biostratigraphic analysis. A similar lack of biostratigraphic control applies to the overlying Devonian succession. We present the results of a palynological study of core material from wells KTG-01 and S05-01. Relatively low-diversity and poorly preserved miospore associations were recorded. These, nonetheless, provide new insights into the regional stratigraphic development of the pre-Carboniferous of the SW Netherlands. The lower two cores from well KTG-01 are of a late Silurian (Ludlow–Pridoli Epoch) to earliest Devonian (Lochkovian) age, confirming that these are the oldest sedimentary strata ever recovered in the Netherlands. The results from the upper cored section from the pre-Carboniferous succession in well KTG-01 and the cored sections from the pre-Carboniferous succession in well S05-01 are more ambiguous. This inferred Devonian succession is, in the current informal lithostratigraphy of the Netherlands, assigned to the Banjaard group and its subordinate Bollen Claystone formation, of presumed Frasnian (i.e. early Late Devonian) age. Age-indicative Middle to Late Devonian palynomorphs were, however, not recorded, and the overall character of the poorly preserved palynological associations in wells KTG-01 and S05-01 may also suggest an Early Devonian age. In terms of lithofacies, however, the cores in well S05-01 can be correlated to the upper Frasnian – lower Famennian Falisolle Formation in the Campine Basin in Belgium. Hence, it remains plausible that an unconformity separates Silurian to Lower Devonian strata from Upper Devonian (Frasnian–Famennian) strata in the SW Netherlands. In general, the abundance of miospore associations points to the presence of a vegetated hinterland and a relatively proximal yet relatively deep marine setting during late Silurian and Early Devonian times. This differs markedly from the open marine depositional settings reported from the Brabant Massif area to the south in present-day Belgium, suggesting a sediment source to the north. The episodic presence of reworked (marine) acritarchs of Ordovician age suggests the influx of sedimentary material from uplifted elements on the present-day Brabant Massif to the south, possibly in relation to the activation of a Brabant Arch system.

We describe a case of cutaneous Larva Migrans in an 8-year-old Caucasian girl. The lesion appeared ten days after a bath in the river in a valley in the north-east of Piedmont. The patient was successfully treated with Albendazole 400 mg daily for 5 days. Autochthonous cases are rare, particularly in northern Italy. Probably the high temperatures and the high degree of humidity favored by the climate changes to which Europe is subjected are favorable to the development of larvae. The diagnosis of cutaneous Larva Migrans should, therefore, be considered also in individuals who have not traveled in geographic areas at risk for the climate.

Hydrocarbon Deposits

Nadym-Pursk oil and gas region has been one of the main areas for the production of hydrocarbon raw materials since the sixties of the last century. A significant part of hydrocarbon deposits is at the final stage of field development. An increase in gas and oil production is possible subject to the discovery of new fields. The search for new hydrocarbon deposits must be carried out taking into account an integrated research approach, primarily the interpretation of seismic exploration, the creation of geological models of sedimentary basins, the study of geodynamic processes and thermobaric parameters. Statistical analysis of geological parameters of oil and gas bearing complexes revealed that the most promising direction of search are active zones — blocks with the maximum sedimentary section and accumulation rate. In these zones abnormal reservoir pressures and high reservoir temperatures are recorded. The Cretaceous oil and gas megacomplex is one of the main prospecting targets. New discovery of hydrocarbon deposits are associated with both additional exploration of old fields and the search for new prospects on the shelf of the north. An important area of geological exploration is the productive layer of the Lower-Berezovskaya subformation, in which gas deposits were discovered in unconventional reservoirs.

The problem of dependence of the Russian economy on raw materials remains. The growth of non-primary non-energy exports was approved as one of the priorities in Russia. Updating the national project increases the importance of its institutional support in legislation. The question arises of the sufficiency of institutional reflection of non-resource exports. The purpose of the article is to generalize approaches to the priorities of non-resource exports, to develop methodological tools and to assess the representation of the topic in conceptual documents on the example of the regions of the North-Western Federal District. The research methodology is based on the content analysis of documents using the Istio service. The basis of the study was the conceptual documents of the NWFD regions with export topics. The categories of non-primary exports are highlighted. The socio-economic Development Strategy is the main document approving the region’s non-resource exports. A research program and methodological support for assessing the representation of non-primary exports in documents have been developed. The differences in the institutional support of non-primary exports are revealed. Of the 11 regions, 8 contain a target indicator of non-primary non-energy exports. Kaliningrad and Murmansk oblasts are recommended to include it in the Strategy in order to form institutional support for overcoming the problem of commodity dependence. A classification of regional documents providing institutional support for the export strategy has been developed. For the first time, the assessment contains scientific novelty and can help to understand the need to form a scientific concept of non-resource exports.
