The purpose of this research is to investigate the mechanical and electrical properties of nano structured cordierite. Nano grain size powders were synthesized through mechanical activation by high-energy ball milling of the starting powders containing 34.86 wt% Al2O3, 51.36 wt% SiO2, and 13.78 wt% MgO. Samples were prepared by conventional and microwave sintering at 1390°C. SEM observations il...

ABSTRACTBackground; Schizophrenia recurrence is caused by many factors, one of which family factors. Family very important for people with schizophrenia, where the roles and functions to provide an affective function meet psychosocial needs members in providing affection. Objective; This study was conducted aim knowing correlation between cohesion schizophrenic patients at Dr. Soetomo Hospital ...

ABSTRACTBackground: Preterm birth, if not actively managed with developmental supportive care, can significantly contribute to neurodevelopmental compromise. Use of appropriate positioning aids helps with mimicking the intrauterine environment and facilitating neuromuscular development. Herein, we aimed to determine the effectiveness of snuggle up positioning aids on clinical outcomes of preterm (

5(6)-carboxy-rhodamine 110 isomers were rapidly synthesized by condensation of 3-aminophenol and trimellitic anhydride using microwave irradiation as heating method. after esterification of the two isomers, separation and hydrolyzation provided target products,5-carboxy-rhodamine 110 and 6-carboxy-rhodamine 110, in high yields. the results shows microwave irradiation can effectively reduce the ...

Artificial bee colony algorithm (ABC) developed by inspiring the foraging phenomena of natural honey bees is a simple and powerful metaheuristic optimization algorithm. The performance single objective ABC has been well demonstrated implemented to different design problems from elec-trical mechanical civil engineering. Its efficacy anticipated in multi-objective multilayer microwave dielectric ...

Hyssopus of­ficinalis L. is one of the most important medicinal plants. Medicinal herbs are contaminated by microorganisms. Conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

WiMAX (Worldwide Interoperability for Microwave Access) is a promising technology which can offer high speed voice, video and data services upto the requirements at the customer’s end. The objectives of this paper is to evaluate the Performance evaluation of a WiMAX system under various diversity schemes (Selection combining, Maximal ratio combining and Equal gain combining), employing differen...

This paper will describe the SMOS concept in terms of instrument (characteristics) investigates the main aspects of the retrieval capabilities of the 2-D microwave interferometer for monitoring soil moisture, vegetation biomass and surface temperature. The analysis is based on model inversion taking into account the instrument characteristics. The standard error of estimate of the surface varia...
