در این مقاله با استفاده از دو مدل Calza-Bini و مدل گپ توصیف شده در کد Relap5 برای ضریب انتقال حرارتی گپ (فضای خالی بین قرص سوخت و غلاف) به محاسبهی ضریب هدایت گپ در فواصل محوری مختلف در مجتمعهای مختلف سوخت تابش ندیده در رآکتورهای نوع VVER-1000 پرداخته شده است. با توجه به وابستگی دو مدل فوق به دمای سطح خارجی سوخت و دمای سطح داخلی غلاف، ضریب هدایت گپ با استفاده از دو روش تزویج مدل ضریب انتقال حر...

When analysing the current financial crisis the temptation might arise to attribute all the responsibilities to the excesses of the US financial system. I think this would be a mistake. While excessive debt creation and risk mispricing are clearly the root cause of the crisis, we should not forget that in order to make a market you need buyers and sellers. And this crisis is as much a crisis of...
I would first like to share with you the caution that policy-makers must have in uncertain times like those we are living in. Our words are carefully listened and read by economic agents and market participants, who try to get a better understanding of economic developments and possibly anticipate policy decisions. In these circumstances the safest thing would be to keep quiet, thus avoiding cr...

This topic has not featured prominently in the speeches given by central bankers in recent decades. But the escalating financial crisis since last autumn has pushed the theme to centre stage. Central banks throughout the world have been responding to the crisis by taking both conventional and unconventional policy measures. It is important to have a good understanding of the unconventional poli...
Using simultaneous acquisition from multiple channels of a radio-frequency (RF) coil array, magnetic resonance inverse imaging (InI) achieves functional MRI acquisitions at a rate of 100ms per whole-brain volume. InI accelerates the scan by leaving out partition encoding steps and reconstructs images by solving under-determined inverse problems using RF coil sensitivity information. Hence, the ...
In a study of the parasite fauna of the European eel (Anguilla anguilla L.) in northwest Spain, we found frequent mixed infection of branchial tissues by the myxosporidian Myxidium giardi (prevalence 95%) and by two monogeneans (Pseudodactylogyrus anguillae and P. bini; joint prevalence 56%). All three species are common parasites in this host. In one of the 323 eels examined, hyperparasitism o...
The following case of Still's disease is reported because of the unusually full pathological data that were available and because of the light these throw on the nature of the disease. Still's disease is defined clinically as a form of chronic arthritis with swelling of the lymph glands and spleen. The swellings of the joints and lymph glands are usually multiple and symmetrical. The disease ge...
