Tourism, Scientific, and Didactic Potential of the Ultrabasic-Alkaline Intrusion in Afrikanda with Perovskite Mineral (Kola Peninsula, N Russia) and of the Related Built Heritage

The present article is an example of research on the tourism, scientific, and teaching potential of the ultrabasic-alkaline intrusion with perovskite minerals in Afrikanda (Kola Peninsula, North Russia) and the possibility of its development as part of a local geopark site. A proposal to create a protected zone in this site, to expose sites of geological, natural, historical, and tourist interest is presented. Didactic routes and locations of geo-point visitors are proposed. Currently, there are numerous quarries and other mining objects of high historical, technical, and geological value. In the vicinity, there is a trough lake and post-glacial formations that can supplement knowledge about this region and add interest to would-be visitors. The remains of a historical camp for workers and miners are also visible in the intrusion area. In the vicinity of Afrikanda village, there is an international railroad line to Murmansk and St. Petersburg with a working railroad station. The place has high historical and geological potential for tourists and very rare and interesting mineralization. The last is a key value. The location is associated with 30 alkaline intrusions in NE Fennoskandia. There are opportunities to create a museum with a park where, with relatively little funding (most of the existing infrastructure buildings are in good condition), the intrusions can be shown to tourists. We proposed a conservation area with exposures, quarries, mine infrastructure, and historical sites, along with the location of geosites, hiking trails, and a geo-point for visitors. These sites are prospective for the economic revival of Afrikanda village and can protect the unique exposures.

NEURAL NETWORK CLASSIFIER OF ENERGY FACILITIES OPERATING MODES AND ITS RECOGNITION ABILITY ASSESSMENT AT DIFFERENT NUMBER OF PRECEDENTS

Classical algorithms of relay protection construction do not use all available information base and therefore cannot provide the highest possible sensitivity with guaranteed selectivity. These algorithms, as a rule, concentrate different information, as a result of which it is partially lost. For example, the resistance relay operates with complex resistance, that is, two real parameters, although two complex variables – voltage and current – are used to calculate the complex resistance. This paper shows the solution to the problem of classification of power line operating modes using a neural network algorithm. The simplest neural network, a perceptron, is a universal classifier, since a convergence theorem has been proved for it, showing that if a classification exists, a perceptron of sufficient complexity is able to describe it. The statistical and geometrical interpretations of various algorithms are discussed. The dependence of the quality of the classifier’s work on the distribution of precedents in the training sample, on which the training is based, as well as on the structure and parameters of the neural network, is shown. The recognition ability of the neural network classifier, i.e. the ability to distinguish short circuits within the protected zone from short circuits outside the protected zone at different number of precedents in the training sample, is evaluated. The limits of applicability of such algorithms to the task of classification of object operation modes in electric power industry are shown and recommendations for their practical application are formulated. The results obtained indicate the need to develop methods for training classifiers that are based on a source of informative precedents in the form of a simulation model of the object.

New location of Tulipa mongolica and its phytocenotic confinement in the Trans-Baikal Territory

The article reports on the new location of a rare, narrow-localized miocene-pliocene relic Tulipa mongolicaY. Z. Zhao, in the Trans-Baikal Territory along the south-eastern sandy-rocky slope of the lake Bayn-Tsagan terrace (Ononsky district), as part of the karaganovo-chiovo-vostretsovaya steppe. In the Trans-Baikal Territory, the tulip grows onthe northern border of its range: in the vicinity of the village Budulan, near the town Malyi Bator (Aginsky district) in thebushyed cold-wormwood-kovylnaya steppe; along the northern coast of the lake Zun-Torey, in the village Kulusutai, nearthe town Gydyrgun (Ononsky district) in the karayganovo-raznotravno-kovylnaya steppe. This cenopopulation is locatedon the territory of the protected zone of the Daursky Nature Reserve.

Phreatic Surface Estimation In MSE Wall With Geocomposite Back Drainage

This study proposes a simple mathematic model for approximating the level of phreatic surface inside the protected zone in mechanical stabilized earth wall with back drain installation though the position of phreatic surface at the drainage interface (ho) which reflects the maximum level of phreatic surface in the protected zone. The proposed model was established based on dataset taken from 180 simulation cases caried out in Plaxis environment. Regression results present a combination of significant effects and major role to maximum water level in the protected zone (ho) of a ratio of length from upstream water to the drainage face to the wall height (L/H), a soil permeabilities coefficient (k) and a transmissivity of the drainage material (Tnet). The proposed model can facilitate design of drainage material to achieve desired level of phreatic surface in the protected zone.

Radiation-hygienic characteristic of the protected zones of peaceful nuclear explosions in the Arkhangelsk region

The article presents data on the radiation situation on the territories of the protected zones of peaceful nuclear explosions «Globus-2», «Agat» and «Rubin-1» based on the results of field studies in 2020. Peaceful nuclear explosions were conducted in the Arkhangelsk region for seismic exploration. The results of the radiation-hygienic state of protected zones and radiation safety in the territories adjacent to peaceful nuclear explosions are analyzed by the main indicators: the values of the ambient dose equivalent of gamma radiation, the identification of gamma-emitting radionuclides in situ by field gamma spectrometry, the specific activity of technogenic radionuclides in the soil and tritium in the water of reservoirs and drinking water sources. An assessment of the sanitary condition of the studied territories of protected zones of peaceful nuclear explosions is given. It was found that the levels of the ambient dose equivalent rate of the gamma radiation at all sites are at the level of fluctuations in the natural regional radiation background in the range of 0.08-0.20 microSv/h. On the territory of the protected zone of the peaceful nuclear explosion «Globus-2» were repeatedly identified areas of minor local soil contamination with 137Cs (the previous study was performed in 2011). Increased values of the ambient equivalent dose rate of gamma radiation (0.20 -0.22 μSv/h) and specific activity of 137Cs in two soil samples (154 and 160 Bq/kg, respectively) were found in these areas. The tritium content in the water of water supply sources does not exceed 5 Bq/kg. These values are typical for global levels of this radionuclide in water bodies. Remains of technological equipment were found on the territories of the protected zones of the peaceful nuclear explosions (especially in the protected zone of the explosion «Agat»), as well as rusty metal pipes and barrels, the remains of wooden structures, etc. Information signs installed on dilapidated concrete foundations at the mouths of combat wells of all surveyed peaceful nuclear explosions have subtle inscriptions. The presence of forest thickets in the places where the investigated peaceful nuclear explosions are conducted and their ignition during forest fires is a potential threat to the release of technogenic radionuclides during depressurization of the mouths of combat wells.

On the peculiarities of legal regulation and algorithm for solving the issue of cutting down trees and shrubs in the protective zone of gas pipeline

We present a legal regulation analysis of procedure for cutting down emergency trees and trees and shrubs located in the protected zone of the gas pipeline, which poses a threat to the safety and functioning of gas networks. The purpose of study is to determine the subjects and the proce-dure for cutting down emergency trees in the security zone of gas pipeline, as well as to assess the regulatory regulation of procedure for cutting down emergency trees in the security zone of gas pipeline, taking into account the balance of interests of gas distribution organizations, local authorities and citizens – owners of land plots. The research methodology is based on a sys-tematic approach in the analysis of the legal regulation of the subject of re-search, formal legal, logical methods of cognition, which together ensure the reliability and validity of conclusions and proposals on the algorithm for solving the issue of cutting down trees and shrubs in the protective zone of the gas pipeline. We conclude that there is variability in the regulation of the elimination of emergency trees, taking into account such conditions as the location of the gas pipeline security zone (ownership of territory) and the owner of the land plot on which the trees are located. We state that the pres-ence of tree plantations in the security zone of gas distribution networks is not prohibited by law, but there is a procedure for the owner of land plots and gas networks to remove trees that potentially pose a threat to the safety of the gas pipeline within the security zone. The legislation unambiguously determines that the person who is obliged to carry out work on cutting down trees and sawing off branches is the owner of the land plot. All work on cutting trees must be carried out taking into account the interests of the gas distribution organization, the owner of the gas pipeline and a real threat to the safety of the gas pipeline. We formulate recommendations for effective building of interaction between subjects interested in resolving the problems of finding emergency trees in the protected zone of the gas pipeline.

UAVs are considered depending on the design. The author made a conclusion about the necessary type of UAV for monitoring the condition of the coast and water protection zones of the Belgorod reservoir. The main technical characteristics of the recommended aircraft UAVs are presented in this paper as well.

On the Borderline: Who Is a “Traditional Inhabitant” under the Torres Strait Treaty?

The Torres Strait Treaty between Australia and Papua New Guinea (“PNG”) came into force in 1985. This unique treaty, which defines the maritime, seabed and fisheries boundaries between Australia and PNG, is recognised as one of the most complex, but imaginative maritime delimitation solutions in existence. The Treaty creates a Protected Zone with a view to safeguarding the traditional way of life and livelihood of traditional inhabitants of the Torres Strait and adjacent coast of PNG. Traditional inhabitants are allowed relatively unrestricted cross-border movement into the Protected Zone for the purpose of performing traditional activities. “Traditional inhabitants” are defined by the treaty, but the relevant provision is ambiguous and the question of who is within the terms of the Treaty is highly contentious. The problem is exacerbated by the competing layers of law which govern the Strait and surrounding Borderlands, and by the dissonance between State law, customary laws, and the practical application of the Treaty. This paper looks at the meaning of “traditional inhabitants” and some of the other issues surrounding this question.
