Изучены основные морфометрические характеристики ледников Малый Азау и Гарабаши: площадь и длина с помощью полигонов изолиний границ ледников для разных временных интервалов (от одного до десяти и более) на основе программного приложения ArcGis и Calculate Geometry. Общие темпы деградации ледника Малый Азау с 1957 по 2015 г. значительно увеличились, достигнув своего максимума в период с 2002 по 2012 г. Сокращение общей площади на леднике Малый Азау за периоды составило: 2002–2007 гг. – 84,6 тыс. м2; 2007–2009 гг. – 52,5 тыс. м2; 2009–2012 гг. – 82,3 тыс. м2; 2012–2015 гг. – 60 тыс. м2. Уменьшение общей длины на леднике Малый Азау за периоды составило: 2002–2007 гг. – 112 м; 2007–2009 гг. – 87 м; 2009–2012 гг. – 50 м. Общие темпы деградации ледника Гарабаши с 1957 по 2015 г. незначительно замедлились. Максимальные темпы сокращения площади ледника Гарабаши в XXI в. были отмечены в период с 2007 по 2015 г., а уменьшение длины – в период с 2009 по 2015 г. Сокращение общей площади на леднике Гарабаши за периоды составило: с 2002 по 2007 гг. – 32,8 тыс. м2; 2007–2009 гг. – 21,4 тыс. м2; 2009–2011 гг. – 27,0 тыс. м2; 2011–2012 гг. – 23,7 тыс. м2; 2012–2014 гг. – 25,1 тыс. м2; 2014–2015 гг. – 14,2 тыс. м2. Общие темпы отступания ледника Гарабаши замедлились: с 2002 по 2015 г. для западного языка с 41 м до 17 м, а для восточного – с 35 м до 19 м. Геохимический анализ талых проб на ледниках Гарабаши и Малый Азау выявил геохимическую аномалию свинца. Содержание свинца в образцах превышает ПДК от 2,5 до 7,5 раза. Средние значения содержания свинца на ледниках составили: Малый Азау 74±15 мкг/л и Гарабаши 230±50 мкг/л.","PeriodicalId":246793,"journal":{"name":"Успехи современного естествознания (Advances in Current Natural Sciences)","volume":"65 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":"129570734","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}

ПЗЛП располагаются перпендикулярно вредоносным юго-восточным ветрам. Межполосное расстояние составляет 400–420 м. Полосы созданы из дуба черешчатого (Quercus robur) и березы повислой (Betula pendula). Лесистость пашни составляет 4,5%. Система ПЗЛП является завершенной. Показатель защищенности прилегающих угодий – более 80%. Повышение урожайности культур севооборота в системе ПЗЛП происходит под влиянием конструкции, которая формирует микроклимат прилегающих полей. Воздействие микроклиматических показателей на динамику урожайности пшеницы зависит от увлажнения вегетационного периода. В средний (гидротермический коэффициент – ГТК=0,65) и средневлажный (ГТК=0,88) годы на урожайность пшеницы, высеянной под защитой лесных полос, наибольшее влияние оказывают: влажность воздуха, дефицит водного баланса и температура воздуха. В очень влажный (ГТК=1,81) и влажный (ГТК=1,15) годы микроклиматические показатели воздействуют на урожайность культуры по значимости в следующем убывающем порядке: температура и влажность воздуха, дефицит водного баланса. В средний сухой (ГТК=0,45) и сухой (ГТК=0,30) годы на урожайность пшеницы влияют дефицит водного баланса и влажность воздуха. Воздействие конструкции ПЗЛП и удобрений на урожайность пшеницы также зависит от года увлажнения выращивания культуры: в средние – с небольшим преимуществом удобрений (до 7,3%), во влажные годы влияние удобрений возрастает до 67,7%, в засушливые – превалирующее значение в формировании урожая культуры приобретает конструкция ПЗЛП – до 18,8%.

When studying Lake Kara-Kel, extensive material was obtained by stationary and expeditionary methods. Complex indicators of water quality were used for hydro- chemical assessment of the lake surface waters. Trophic assessment of the aquatic ecosystem was performed using ITS calculation. As a result of the survey of the lake and the hydrochemical analysis of the water, a comprehensive assessment of the lake landscape was given. The lake has a small size, the mirror area is 2.7 hectares. The bottom relief is flat, the depth drop is uniform, the maximum depth reaches 9.0 meters. The average annual value of the water pollution index was 0.91 and characterized the surface water of the lake «clean» 2 quality classes. The specific combinatorial index of water pollution in the reporting year amounted to 1.7 and characterized water as “slightly contaminated” class 2. No critical contamination was observed. Exceeding the MAC was observed for 5 ingredients of the chemical composition. Lake Kara-Kel is characterized by a moderate amount of nutrients dissolved in water, a high content of dissolved oxygen, and weak mineralization. Over the past nine years, the quality of the surface water of the lake has significantly improved. Concentrations of aluminum, manganese, copper and petroleum prod- ucts in 2021 in lake water did not exceed the MAC; and the concentration of total phenols decreased by 4.7 times. The development of tourism in combination with the rational use of water bodies and the conduct of geoecological monitoring is a promising solution to the socio-ecological and environmental tasks of sustainable mining development of the republic.","PeriodicalId":246793,"journal":{"name":"Успехи современного естествознания (Advances in Current Natural Sciences)","volume":"1 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":"129155012","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}

A hydrophilic-lipophilic ratio HLR is associated with the angle θ ow and it is also a wetting characteristic. The wetting heat of solid particles of insoluble dry powder with water ΔH w and the wetting heat with oil ΔH o were measured by the calorimetric method in this work. By the values ΔH w and ΔH o the hydrophilic-lipophilic ratio was determined as the ratio of the wetting heats, and the contact angle θ ow was calcu-lated. The polydisperse isomorphic solid particles of different nature were investigated: lamellar microtalc particles Talcon T-20 and particles of food solid emulsifiers. As food emulsifiers, powders of plant origin were used: ground cinnamon, ground ginger, mustard powder, ground nutmeg. In the case of talc particles of micrometric size, the value of the contact angle θ ow was equal to 97 ° (and HLR <1, respectively) for the water – olive oil interface and it was equal to 85 ° (HLR > 1) for the water – hexane interface. In the case of food powders, the values of the contact angles θ ow were in the range of 56–66 ° (and HLR > 1, respectively). All the values of HLR and the contact angle θow are in good agreement with the results of using these particles as stabilizers of Pickering emulsions. When the ratio HLR was greater than 1, stable direct emulsions were formed using food powders or talc in the case of using a saturated hydrocarbon as the non-polar phase. When the ratio HLR is less than 1, stable reverse emulsions were formed (from talc particles in the case of using olive oil","PeriodicalId":246793,"journal":{"name":"Успехи современного естествознания (Advances in Current Natural Sciences)","volume":"111 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":"124643726","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}
