طیف تشدید اسپین الکترونی copper dipyridine dichloride (cpc) copper di-4-tert.-butyle-pyridine dicholoride (ctc) اندازه گیری شده است . این سیستم ها از مولکولهای زنجیری خطی با پیوند اسپین نسبتا" بزرگی بین زنجیرها تشکیل شده اند. یک بستگی زاویه ای بصورت تابعی از 4 در محل خطوط تشدید مشاهده گردید. اندازه گیری خودگیری ویژه (susceptibility) جفت شدگی اسپین ها را رد کرد ولی برای تغیر مشاهدات لازم است یک ...
This paper addresses the susceptibility of CAN networks to RF noise when applied to signal ports of a transceiver. The impact of RF interference on CAN is evaluated at equipment level in two measurement tests, injecting noise by means of DPI and BCI. The noise injection paths for the different tests are characterized and compared. The main factors contributing to noise rejection in CAN differen...
Background and Aim: Diabetic foot complication and its amputation is one of the most physical and emotional disabilities in diabetic patients.

INTRODUCTION – A hyperoxic challenge has been shown to provide a method for the measurement of venous blood volume (1) and calibrated BOLD (2). The administration of a hyperoxic gas mixture (FIO2>0.21) increases venous haemoglobin saturation causing an increase in the BOLD weighted signal. However, increasing oxygen concentration in the nasal cavity may itself lead to artefactual signal changes...
aspergillus terreus is emerging as an etiologic agent of invasive aspergillosis among patients undergoing cancer chemotherapy, haematopoetic stem-cell transplantation, or solid organ transplantation worldwide. infections caused by aspergillus terreus has become important due to less susceptibility to antifungal drags, resistant to amphotericin b and therefore, poor clinical outcome and higher m...
