In problems of choosing ‘aspirations’ for TU-games, we study two axioms, ‘MW-consistency’ and ‘converse MW-consistency.’ In particular, we study which subsolutions of the aspiration correspondence satisfy MW-consistency and/or converse MW-consistency. We also provide axiomatic characterizations of the aspiration kernel and the aspiration nucleolus. 2002 Elsevier Science B.V. All rights reserved.
Microwave (MW) vacuum dehydration using temperature to control the level of MW power demonstrated potential in improving the performance of the process. Product surface temperature measured by an infrared temperature sensor was used to control MW power at any level between 0 and 3 kW. Multiple linear regression analysis indicated an r2 = 0.942 for prediction of final moisture content and r2 = 0...
The goal of this study was to investigate whether glucocorticoids (GCs) take part in cognition impairment after exposure to chronic low-power-density microwave (MW) fields. We exposed Wistar rats to a 2.45-GHz pulsed MW field at an average power density of 1 mW/cm(2) for 3 h daily, for up to 30 days. Our results show that MW-exposed rats had significant deficits in spatial learning and memory p...
پیل های سوختی میکروبی رسوبی قادر به تبدیل طیف وسیعی از مواد آلی موجود در رسوبات اکوسیستم های آبی به جریان الکتریسیته می باشند. در این تحقیق به بررسی پتانسیل بالقوه 4 منبع رسوبی مختلف شامل: دریا، حوضچه پرورش ماهی، چشمه محلی و رودخانه محمود آباد به عنوان مولد جریان الکتریسیته پرداخته شد. رسوبات حاصل از رودخانه در مقایسه با سایر رسوبات مورد آزمایش قرار گرفته بالاترین دانسیته توان (mw/m2 09/37 ) را...
Mind wandering (MW) reflects a shift in attention from taskrelated to task-unrelated thoughts. It is negatively related to performance across a range of tasks, suggesting the importance of detecting and responding to MW in real-time. Currently, there is a paucity of research on MW detection in contexts other than reading. We addressed this gap by using eye gaze to automatically detect MW during...
the paper will provide a summary of all lifelines performance in this strong earthquake. the paper will discuss the damage, emergency response, and recovery of electric power, telecommunication, transportation (roads and bridges), seaports, airports, water and wastewater, and their facilities. the impact as a result of the lifelines service interruption will be discussed; most important is the ...
دراین پروژه سیستم خنک کننده راکتور تحقیقاتی سازمان انرژی اتمی مورد بررسی قرار گرفته و باتوجه به میزان افت فشار درقلب ، لوله و اتصالات ، ماکزیمم دبی سیال خنک کننده محاسبه شده است و ازروی آن، ماکزیمم توان راکتوراز جنبه مسائل حرارتی و هیدرولیکی در آرایشهای مختلف قلب بدست آمده است . آنگاه جهت افزایش توان راکتور به mw 10 حداقل دبی مورد نیاز سیال خنک کننده محاسبه گردیده است . درجدول زیربطور خلاصه دبی...
Coagulation behavior of aluminum chloride and polyaluminum chloride (PACl) for removing corresponding disinfection byproduct (DBP) precursors was discussed in this paper. CHCl3, bromine trihalomethanes (THM-Br), dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) formation potential yields were correlated with specific ultraviolet absorbance (SUVA) values in different molecular weight (M...
Interest in mind wandering (MW) has grown in recent years, but few studies have assessed this phenomenon in older adults. The aim of this study was to assess age-related differences between young, young-old and old-old adults in MW using two versions of the sustained attention to response task (SART), one perceptual and one semantic. Different indicators were examined (i.e., reported MW episode...
A previous study showed β-glucan with low molecular weight (MW, 1.56×10(5) g/mol) bound more bile acid and produced greater amounts of short-chain fatty acids (SCFA) than did β-glucan with high MW (Mn=6.87×10(5) g/mol). In the current study, β-glucan extracted from oat flour was fractionated into six different MW levels (high MW, 7.09×10(5); low level 1 (L1), 3.48×10(5); L2, 2.42×10(5); L3, 1.6...
