The fauna of Yakutia is rich and diverse. The fauna of terrestrial vertebrates is represented by 4 species of amphibians, 2 – reptiles, 280 – birds and 63 species of mammals. Of the large ungulates in the republic live elk, red deer, reindeer, mountain (snow) ram – Chubuk, roe deer and musk deer are widespread. Of the predators – brown, on the Arctic coast – polar bears, wolves, lynx, wolverine, red fox, arctic fox, and columns. Under the influence of anthropogenic activity and under the influence of climatic disasters, global changes in the habitat of wild animals in the region occur, which determines the relevance of the research topic. The identification of changes in the habitat of wild animals at the present stage is possible only through the organization of continuous monitoring of the state and changes in natural territorial complexes and, first of all, landscapes within which populations of wild plants and animals exist, multiply and migrate. Monitoring the state of vegetation according to aerospace images makes it possible to determine its seasonal state and change. Recently, changes in the areas of the natural habitat of wild animals have been identified, therefore, a thorough analysis of the causes that provoke this phenomenon is required. Such an analysis formed the basis for organizing measures to stop their negative impact. A study on this topic showed that modern GIS technology allows you to build 3D terrain models with the ability to interactively manage information about the","PeriodicalId":246793,"journal":{"name":"Успехи современного естествознания (Advances in Current Natural Sciences)","volume":"265 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124316524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mironov","doi":"10.17513/use.37459","DOIUrl":"https://doi.org/10.17513/use.37459","url":null,"abstract":"Yakutsk, e-mail: bsdpsv@mail.ru, mironoff22ykt@mail.ru A program has been developed for calculating the indices of a non-transport complicated excavation scheme. The excavation scheme considered in the article is adapted to the conditions of the permafrost zone and is intended for development of the blasted overburden massif, which is subject to repeated freezing, using the non-transport technology. The blasted rock mass is worked out in layers along the entire length of the excavator block. At the same time, a walking dragline excavator is located on the surface of the block, and moving along the block, sequentially removes the surface layer of the rock. This excavation scheme and the block mining procedure ensure the maximum possible performance of the dragline excavator in conditions of repeated freezing of the blasted rock, since the excavator removes the surface layer that has already undergone some thawing under the influence of solar insolation. To calculate the indicators of this non-transport complicated excavation scheme, the parameters of the excavator entry in the pillar are first entered, then the parameters of drilling and blasting operations are set, which determine the configuration of the breakup of the blasted rock mass, and the model of the dragline excavator is set. To calculate the volume of excavation work, the program provides 4 typical options for the formation of the configuration of the rock breakup of the blown overburden ledge. The effect of secondary freezing on the efficiency of the excavator is taken into account by a special algorithm for calculating the dragline performance, which assumes a separate calculation of the productivity and operating time for each excavator block being worked out. The main input data for calculating the dragline performance are the dimensions of the excavator entry, the thickness of the rock layer removed from the bottom of the excavator for a certain period of time, and the average temperature of the rock in each excavation layer. To calculate the performance of an excavator during the development of each layer, the previously established relationships between the temperature of the rock in the bottom hole and the time of the dragline’s working cycle are used. In connection with the temperature and climatic period of mining, the performance of the excavator, the time for working out each excavation layer, and then the time for working out the","PeriodicalId":246793,"journal":{"name":"Успехи современного естествознания (Advances in Current Natural Sciences)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114713544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Belova","doi":"10.17513/use.38030","DOIUrl":"https://doi.org/10.17513/use.38030","url":null,"abstract":"The article provides data on the composition of solutions obtained on the basis of experimental laboratory modelling of physical-chemical interaction in the ‘water-material’ waste dump system. Long-term storage of gold cyanidation cakes in the tailings of gold-processing factories can lead to the pollution of surface water bodies. This pollution is a result of active and passive interaction of atmospheric precipitation with the waste material. The solution in equilibrium with the leaching cakes has a pronounced alkaline reaction with pH value of > 9.0. During the first storage period the pH of the solutions increases as a result of hydrolysis reactions of excess reagent cyanides of alkali or alkaline-earth metals. Then the solutions pH is observed to decrease gradually towards the end of the first month of experimental observation. Sulphate ions, formed by the oxidation of metal sulphides in an alkaline medium, cyanide ions and heavy metal ions are accumulated in the solution due to the destruction of cyanide complexes with heavy metal ions, such as copper, zinc, cobalt, etc. The presence of arsenic in the drainage solutions in concentrations exceeding the maximum allowable concentration (MAC) is caused by oxidation of arsenopyrite contained in the source ore. Physical-chemical interactions result in exceeding of MACs for copper, cobalt, zinc, vanadium, chromium, molybdenum and wolframium in the drainage water established for fishery. Taking into account that the vast majority of water bodies in Kamchatka are spawning waters, it is recommended to treat drainage water using sorption methods. Local mineral aluminosilicate raw materials such as zeolites, which have an increased sorption capacity in neutral and slightly alkaline media, can be recommended to use as sorbents.","PeriodicalId":246793,"journal":{"name":"Успехи современного естествознания (Advances in Current Natural Sciences)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114905061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Полевые исследования были проведены в 2020–2021 гг. на территории тестового полигона «Амара». Цель исследований – разработка фотоэталонов участков поверхности и определение основных характеристик агроландшафтов, включая тип почвы, степень ее деградации, определение вида и пространственного распределения деградации, состава фитоценозов для верификации космоснимков. Предмет исследований – вид и степень деградации сельскохозяйственных угодий. Дешифрирование космоснимков с космических аппаратов Sentinel 2, Landsat 8, а также сверхвысокого разрешения со спутников WorldView-3,4 являлось основой для геоинформационного картографирования и выявления состояния сельскохозяйственных ландшафтов и их оценки. С использованием данных полевых исследований совместно с результатом геоинформационного анализа рельефа территории полевого участка построен опытный профиль и для каждой его точки проведено пространственное позиционирование при помощи GPS-системы, фотоэталонирование территории, отбор образцов почв и ботаническое описание растительности. Установлено, что на исследуемой территории присутствуют плодородные аллювиальные почвы, которые в основном подвержены различной степени засоления. Главными результатами исследований является верификация данных спутниковой съемки сверхвысокого разрешения на основе данных эталонирования территории тестового полигона для оценки состояния агроландшафтов и возможности агролесомелиорации сельскохозяйственных земель. В результате проведенных исследований с использованием геоинформационных технологий по космоснимкам установлено, что наибольшую часть тестового участка «Амара» занимают угодья с очень сильным и сильным засолением. Такие площади выводятся из использования и в настоящее время зарастают рудеральной растительностью. Угодья со средним уровнем засоления занимают поля сельскохозяйственных культур, где проводится выращивание сельскохозяйственных культур.

The article considers the extraction of zinc and cadmium from wastewater using SF-5 cation exchanger. The bulk of zinc migrates through the hydrosphere. The accumulation of heavy metals along the food chain is an environmental problem for the Tyumen region. Monitoring of the condition of reservoirs showed a doubling of the zinc ion content. This scientific work examines the processes of sorption and desorption of cadmium and zinc ions on the industrial sorbent SF-5, as well as ways to intensify the extraction process. The sorption and desorption process was carried out under dynamic conditions. The exchange capacities were evaluated, which showed that with an increase in the content of hydrochloric acid, the sorption of metals decreases. The depth of extraction of metal ions from solutions with an acidic medium is determined. The obtained experimental data on sorption showed a complication of ion exchange by the processes of complexation of ionogenic groups with zinc and cadmium cations. Desorption and regeneration of cationite was carried out with hydrochloric and sulfuric acid, as well as ammonium salts of these acids. The sorption results were used to calculate the contact area of the cationite with the waste water flow. The relationship between the sorption and desorption processes is shown.The article proposes the calculation of the necessary equipment for wastewater treatment, the ion exchange capacity of cationite under various conditions is estimated, the conditions for desorption of impurities and regeneration of cationite are given. Calculations have shown that 6 ion exchange columns will be required to purify a given amount of wastewater up to MPC.
