Wheat straw burial has great potential to sustain rice production under alternate wetting and drying(AWD)irrigation.A field experiment was conducted with three wheat straw burial treatments,including without straw burial(NSB),with light straw burial of 300 kg/hm^(2)(LSB)and dense straw burial of 800 kg/hm^(2)(DSB),as well as three AWD regimes:alternate wetting/moderate drying(AWMD),alternate wetting/severe drying(AWSD)and alternate wetting/critical drying(AWCD).The rice growth and grain quality were higher in LSB and NSB than those in NSB under the same AWD *** AWMD×DSB treatment resulted in the highest yield,brown rice rate,milled rice rate,amylose content and protein ***,the AWCD×NSB treatment led to the lowest yield,brown rice rate,milled rice rate,amylose content and protein *** active absorption area and nitrate reductase activity of roots were higher in the AWMD×DSB treatment than those in the AWCD×NSB treatment,as the former increased organic carbon and nitrogen contents in the rhizosphere,whereas the latter reduced their *** soluble protein content and glutamine synthetase activity were greater in the AWMD×DSB treatment than those in the AWCD×NSB *** activities of superoxide dismutase and catalase were higher in the AWMD×DSB treatment compared with the AWCD×NSB treatment,leading to the amelioration of oxidative cell injury,as shown by a lower malonaldehyde *** study suggested that farmers should implement AWMD irrigation after leaving the straw residues in the field,followed by deep tillage to improve soil quality and mitigate the drought stress cycles of *** approach can improve rice growth and grain quality and alleviate the problems of disposal of straw residues and water scarcity for sustainable rice production.

Breast Cancer Hyperthermia Treatment Based on Slotted Patch Antenna at 2.45 GHz

引用

Circuits and Systems 2023年第5期14卷 10-18页

作者： Mussa Elsaadi Rema hamad Electronic and Electrical Engineering Tobruk University Tobruk Libya Electronic and Electrical Engineering University of Omar Al-Mukhtar Beida Libya

The present work proposed a simple model for breast cancer hyperthermia treatment at 2.45 GHz. The proposed model involves nine-element antennas alongside a numerical breast comprising multiple tumors. Using a coupled EM-Thermal simulation in the CST suite, the simulated results for a single antenna showed a reflection coefficient (S11) better than -47 dB and demonstrated a bandwidth of 78 MHz. The specific absorption rate (SAR) as a function of input powers was examined inside the breast tissues, where it exhibited a promising performance higher than 3 W/kg at the tumor volume when the applied power was at a reasonable level of 1.5 W whereas it was well attained under the recommend IEEE level of 1.6 W/kg through the surrounded health tissues. Taking into consideration nine-element antennas covering the breast containing two different located tumors, the maximum temperature as a function of treatment time was presented at which a resulting temperature of 43°C was obtainable within 10 minutes, favored for hyperthermia purposes. Considering the maximum power level of 1.5 W, the potential use of applying three-element antennas, simultaneously with 0.5 W, could be achieved.

Studying the Preheating Effect on Certain Mechanical Properties of the Coating Layer by Vacuum Ion Plasma Coating

引用

Modern Mechanical Engineering 2015年第4期5卷 105-111页

作者： Abdul Jaleel hamad Majeed Industrial Engineering Department University of Jordan Amman Jordan

The present paper is concerned with the study of two main points: clarifying the effect of preheating on the surface microscopic shape of coating layer by vacuum ion plasma coating technology and on the amount of micro-hardness besides studying the properties of the surfaces that concern the parts of the mechanical system because of their direct and active effect on the machine efficient performance and machine life in general and their important effect on the product efficiency. As known, the instruments that measure the traditional roughness give us numbers and charts that, to a certain extent, describe the actual state of the surface shape within limited range of accuracy, but it has become necessary to find more accurate methods that suit the development obtained in industry, namely, the important applications like aircraft missiles and others. One of the suggested solutions for this is to get benefit of average fractal dimension for the surface by the help of the new technologies which, in return, help in the possibility to determine the surface state with high accuracy that matches the importance of application.
