This study aims to expand our understanding of environmental performance by adopting exploration and exploitation concepts, which are key types of firm innovation. We reveal exploration and exploitation as two important antecedents of proactive and reactive environmental performance. We also identify the conditions under which the distinct effects of these two types of innovation are moderated....
sleep deprivation has negative effects on performance and resulted in elevating of mortality risk, cardiovascular disease and diabetes. the purpose of this study was to investigate the effects of 30 hour sleep deprivation on serum levels of c-reactive protein, blood lactate, muscular strength and physiological factors of rast test in active students. the present study was a semi-experimental on...
Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...
The textile dyes are considered as major environmental problems. The dyes can be removed by various methods. Therefore, this study aimed to evaluate the adsorption rate of Reactive Red 198 (RR198) from aqueous solution by activated Azolla filiculoides. This was an empirical-lab study. The Azolla was used as an adsorbent to remove Reactive Red 198 dye. The effect of various parameters was invest...
Mobile ad Hoc networks (MANETs) can make dynamic changes in topology. The most realistic characteristic which differentiates MANETs from other networks is that it is capable of changing its location. The result of the surveys over the last 5 years, show that it can overcome the two difficulties such as congestion and communication between nodes. Different routing algorithms are used while maxim...
این پایان نامه در پنج فصل به شرح زیر تدوین گردیده است که در فصل اول به مقدمه ای در خصوص تعاریف مختلف توان راکتیو در محیطهای غیر سینوسی و همچنین روشهای اندازه گیری توان راکتیو برای رسیدن به بهترین حالت جبرانسازی توان راکتیو می پر دازیم در این بخش به منظور آشنایی بیشتر با موضوع، تحقیقات کتابخانه ای در موضوعات مورد بحث شامل سابقه تاریخی و کارهای انجام شده قبلی این زمینه به طور مختصر توضیح داده شده...
Futbolun talepleri son zamanlarda önemli ölçüde değişmiş ve artmıştır. Günümüzde bir futbol müsabakası sırasında, oyuncuların daha fazla güce sahip olmaları, yüksek şiddet gerektiren hareketleri sık sayıda yapmaları uzun mesafeleri kat etmeleri gerekmektedir. Bu çalışmanın amacı futbolcuların sprint, çeviklik reaktif performansları arasındaki farklılıkları araştırmaktır. Çalışmaya toplam 59 erk...
