Ploughing and fertilization practices in rice-wheat system have deteriorated the soil carbon (C) pools. Conservation agriculture (CA) based management approaches have proven to enhance C sequestration and reverse the loss of soil-organic-carbon (SOC), which further enhances soil fertility. Different fractions of SOC pools react to the alterations in management practices and indicate changes in SOC dynamics as compared to total C in the soil. Higher SOC levels in soil have been observed in case of reduced/no-till (NT) practices than conventional tillage (CT). However, between CT and zero tillage/NT, total SOC stocks diminished with an increase in soil depth, which demonstrated that the benefits of SOC are more pronounced in the topsoil under NT. Soil aggregation provides physical protection to C associated with different-sized particles, thus, the improvement in soil aggregation through CA is an effective way to mitigate soil C loss. Along with less soil disturbance, residual management, suitable crop rotation, rational application of manures and fertilizers, and integrated nutrient management have been found to be effective in not only improving soil C stock but also enhancing the soil health and productivity. Thus, CA can be considered as a potential method in the build-up of SOC of soil in rice-wheat system.

Vibration analysis of axisymmetric functionally graded viscothermoelastic spheres

引用

Acta Mechanica Sinica 2014年第1期30卷 100-111页

作者： D.K.Sharma J.N.Sharma S.S.dhaliwal V.Walia Department of Mathematics Sant Longowal Institute of Engineering and Technology Department of Mathematics National Institute of Technology

The present study focuses on the analysis of free vibrations of axisymmetric functionally graded hollow spheres. The material is assumed to be graded in radial di- rection with a simple power law. Matrix Frrbenious method of extended power series is employed to derive the analytical solutions for displacement, temperature, and stresses. The dispersion relations for the existence of various types of pos- sible modes of vibrations in the considered hollow sphere are derived in a compact form. In order to explore the character- istics of vibrations, the secular equations are further solved by using fixed point iteration numerical technique with the help of MATLAB software. The numerical results have been presented graphically for polymethyl methecrylate materials in respect of natural frequencies, frequency shift, inverse quality factor, displacement, temperature change, and radial stress.

Healthcare institutions are vulnerable to disruptionfrom events such as earthquakes, fires, and floods, andthe damage incurred can endanger the lives of patientsin the hospital.[1] In this type of scenario hospital staffhave primary responsibility for the hospitalized patients＇safety, since patients are neither fit to respond to sucha disaster, nor do they know how to respond.[2,3] Thesituation becomes more difficult and challenging if thedisaster occurs in critical care areas such as intensivecare units （ICUs） and operating rooms.

Alkali Ionic Conductivity in Inorganic Glassy Electrolytes

引用

Journal of Materials Science and Chemical Engineering 2023年第7期11卷 31-72页

作者： ram Krishna Hona Mandy Guinn Uttam S. Phuyal S’Nya Sanchez Gurjot S. dhaliwal Department of Environmental Science United Tribes Technical College Bismarck USA School of Arts and Science University of Mount Olive Mount Olive USA Intertribal research and resource Center United Tribes Technical College Bismarck USA

Glassy electrolytes could be a potential candidate for all-solid-state batteries that are considered new-generation energy storage devices. As glasses are one of the potential fast ion-conducting electrolytes, progressive advances in glassy electrolytes have been undergoing to get commercial attention. However, the challenges offered by ionic conductivity at room temperature (10−5 - 10−3 S∙cm−1) in comparison to those of organic liquid electrolytes (10−2 S∙cm−1) hindered the applicability of such electrolytes. To enhance the research development on ionic conductivity, the overall picture of the ionic conductivity of glassy electrolytes is reviewed in this article with a focus on alkali oxide and sulfide glasses. We portray here the techniques applied for alkali ion conductivity enhancement, such as methods of glass preparation, host optimization, doping, and salt addition for enhancing alkali ionic conductivity in the glasses.
