| 1 | Development of Magnesium-Dominant Soils Under Irrigated Agriculture in Southern Kazakhstan显示文摘Irrational irrigation practices in the Arys Turkestan Canal command area in the southern part of Kazakhstan have led to the formation of soils with poor physical and chemical properties. To study whether irrigation and leaching practices and/or groundwater rise have contributed to the accumulation of Mg2+ on the cation exchange complex of these soils, historical changes in soil and groundwater quality were used as source data and the Visual MINTEQ model was applied to analyze the chemical composition of water and soils in the study area. The imposed irrigation regime and the leaching of light sierosem soils led to the dissolution and subsequent leaching of inherent gypsum and organic matter from the soil profile. Further, the domination of bicarbonate in the irrigation water promoted weathering of the carbonate minerals present as calcite. The higher concentrations of Mg2+ in comparison to Ca2+ in the irrigation water resulted in the replacement of Na+ by Mg2+ on the cation exchange complex. In the lower part of the command area, shallow groundwater has contributed to the accumulation of Na+ and to a large extent of Mg2+ on the cation exchange sites. | A. KARIMOV M. QADIR A. NOBLE F.

| 2 | Flexible impedance and capacitive tensile load sensor based on CNT composite显示文摘In this paper, the fabrication and investigation of flexible impedance and capacitive tensile load sensors based on carbon nanotube(CNT) composite are reported. On thin rubber substrates, CNTs are deposited from suspension in water and pressed at elevated temperature. It is found that the fabricated load cells are highly sensitive to the applied mechanical force with good repeatability. The increase in impedance of the cells is observed to be 2.0 times while the decrease in the capacitance is found to be 2.1 times as applied force increases up to 0.3 N. The average impedance and capacitive sensitivity of the cell are equal to 3.4 N^(-1) and 1.8 N^(-1), respectively. Experimental results are compared with the simulated values,and they show that they are in reasonable agreement with each other. | Zubair Ahmad Kh S Karimov Farid Touati | 2016 | Chinese Physics B2016，25，2： | 3 |
| 3 | 复合顺倾弱层边坡变形破坏机理研究显示文摘针对复合顺倾弱层边坡易发生破坏的工程难题,以某露天矿采场东帮为研究背景,采用理论分析与数值模拟综合分析了采场东帮的滑坡形式及破坏机理。结果表明:通过极限平衡法对东帮边坡稳定性分析后得出最危险区域的稳定系数为1.27,此数值大于确定的安全储备系数1.2,满足生产对安全的要求。顺倾弱层因生产导致剥、采工程的逐渐变化,将被陆续暴露在坡面上,演化为滑体的下部边界,致使东帮滑坡是以圆弧和弱层共同作用的组合形式;边坡岩体在重力的作用下,上部岩体会挤压下部岩体沿着顺倾弱层发生滑移。弄清边坡破坏形式和机理,能够为优化边坡的空间形态和边坡防滑提供理论依据,保证煤矿高效生产及人员生命安全。 | Karimov Nodirbek | 2022 | 煤炭科技2022，43，1： | 3 |
| 4 | Orange dye polyaniline composite based impedance humidity sensors显示文摘This study presents the fabrication and investigation of humidity sensors based on orange dye (OD) and polyaniline (PANI) composite films. A blend of 3 wt.% OD with 1 wt.% PANI was prepared in 1 ml water. The composite films were deposited on glass substrates between pre-deposited silver electrodes. The gap between the electrodes was 45 μm. The sensing mechanism was based on the impedance and capacitance variations due to the absorption/desorption of water vapor. It was observed that with the increase in relative humidity (RH) from 30% to 90%, the impedance decreases by 5.2 × 10 4 and 8.8 × 10 3 times for the frequencies of 120 Hz and 1 kHz, respectively. The impedance-humidity relationship showed a more uniform change compared to the capacitance-humidity relationship in the RH range of 30% to 90%. The consequence of annealing, measuring frequency, response and recovery time, and absorption-desorption behavior of the humidity sensor were also discussed in detail. The annealing resulted in an increase in sensitivity of up to 2.5 times, while the measured response time and recovery time were 34 s and 450 s, respectively. The impedance-humidity relationship was simulated. | Muhammad Tariq Saeed Chani Kh. S. Karimov F. A. Khalid S. Z. Abbas M. B. Bhatty | 2013 | Chinese Physics B2013，22，1： | 3 |
| 5 | Challenges for the sustainable use of water and land resources under a changing climate and increasing salinization in the Jizzakh irrigation zone of Uzbekistan显示文摘Jizzakh Province in Uzbekistan is one of the largest irrigated areas in Central Asia without natural drainage.In combination with aridity,climate change and extensive irrigation practices,this has led to the widespread salinization of agricultural land.The aim of this study was to identify opportunities to improve the reclamation status of the irrigated area and how best to effectively use the water resources in Jizzakh Province based on investigations conducted between 1995 and 2016.A database of field measurements of groundwater levels,mineralization and soil salinity conducted by the provincial Hydro-Geological Reclamation Expeditions was used in the study.The total groundwater mineralization was determined using a portable electric conductometer(Progress 1T)and the chloride concentration was determined using the Mohr method.The soil salinity analyses were conducted by applying two different methods:(1)the extraction and assessment of the soluble salt content,and(2)using an SM-138 conductivity sensor applied to a 1:1 mixture of soil sample and water.The analyses of the monitoring results and the salt balance in the'irrigation water–soil–drainage water'system clearly demonstrated that the condition of the irrigated land in the province was not significantly improved.Under these conditions,the stability of crop yields is achieved mainly through the use of large volumes of fertilizer.However,excess amounts of mineral fertilizers can also cause the salinization of soils.The average groundwater salinization value in most of the irrigated land(75.3%)fluctuated between 1.1 and 5.0 g/L,while the values were less than 1.0 g/L in 13.1%of the land and in the range of 5.1–10.0 g/L in 10.5%of the land.During the period of 1995–2016 the salinization level of the irrigated land in Jizzakh Province increased slightly and the area could be divided into the following classes:no salinity(17.7%of the total area),low salinity(51.3%),moderate salinity(29.0%),and high salinity(2.0%).Detailed studies of the salt balance in irrigated land,the impact of climate change,increased fertilizer use,and repeated remediation leaching on the groundwater level and mineralization should be conducted in the future,due to the possibility of accelerated salinization,fertility decline,and reduced yields of agricultural crops. | Rashid KULMATOV Jasur MIRZAEV Jilili ABUDUWAILI Bakhtiyor KARIMOV | 2020 | Journal of Arid Land2020，12，1： | 2 |
| 6 | 跨国消费者对干果及其加工品的消费偏好显示文摘随着人们消费水平的提高,各类休闲食品成为人们日常生活的必需品,特别是干果类食品,因其味美且营养丰富而深受消费者欢迎,成为国内外非常畅销的产品,也因此衍生出一个非常好的发展商机。但是,关于干果及其加工品消费行为的现有文献少之又少,该现状与干果及其加工品在国内外市场上的实际情况极不相符。因此,将中国、俄罗斯、乌兹别克斯坦的干果及其加工品消费者作为对象,调查他们的干果及其加工品消费行为,以此得知3个国家消费者多少都会食用干果,一般选择在家中食用,相对喜欢食用葡萄干和谷类早点,消费干果加工品的频率比干果略高。相对而言,乌兹别克斯坦消费者更熟悉干果,在不同场合都会食用干果。对于食用时间而言,中国和俄罗斯消费者一般在上午食用干果,但乌兹别克斯坦消费者一般在下午和晚上将干果作为点心来食用。该结论以期为企业经营的实践和政府政策的制定提供干果及其加工品营销的合理化对策建议。 | 阿布力孜·布力布力 马薇 Karimov Narboy | 2020 | 江苏农业科学2020，48，1： | 2 |
