XIDATION OF ORGANIC MATERIAL as a preliminary to determination of iodine, whether by wet or dry methods, entails loss of iodine if insufficient organic matter is present during the reaction (1, 2, 3). In blood serum, the organic content suffices to prevent this loss when the amount of iodine in the specimen is in the range found in physiological or pathological sera, 0-30 pg./100 ml., as has be...
در این پایان نامه مبدل های امپدانسی بطور خلاصه با عنوان (z-source converter) نامگذاری شده است. این مبدل در همه اشکال انتقال توان بصورت های dc به ac، ac به dc، ac به ac و dc به dc کابرد دارد. مبدل منبع امپدانسی از یک شبکه امپدانسی جالب بین یک منبع تغذیه و بار یا مبدل های دیگر برای دستیابی به ویژگی های منحصربفردی که در vsi و csi وجود ندارد، بهره می گیرد. در مبدل های منبع امپدانسی موانع و محدودیت ...
The central sulcus (CS) divides the pre- and postcentral gyri along the dorsal-ventral plane of which all motor and sensory functions are topographically organized. The motor-hand area of the precentral gyrus or KNOB has been described as the anatomical substrate of the hand in humans. Given the importance of the hand in primate evolution, here we examine the evolution of the motor-hand area by...
MIM Symphony is a recently introduced low-dose-rate prostate brachytherapy treatment planning system (TPS). We evaluated the dosimetric and planning accuracy of this new TPS compared to the universally used VariSeed TPS. For dosimetric evaluation of the MIM Symphony version 5.4 TPS, we compared dose calculations from the MIM Symphony TPS with the formalism recommended by the American Associatio...
In the ICT sector, product-software is an important factor for the quality of the products (e.g. cell phones). In this context, open source software enables firms to avoid quality competition as they can cooperate on quality without an explicit contract. The economics of open source (OS) versus closed source (CS) business models are analyzed in a general two-stage model that combines aspects of...

sodium iodide-131 is administrated for treatment of hyperthyroidism and thyroid cancer. iodine-131 has multiple routs of excretion (urine, saliva, sweat, milk, feces, exhalation) from the body. patients receiving sodium iodide-131 therapy exposes other persons and the environment to unwanted radiation and contamination. the major source of radiation dose from administration of iodine-131 is ext...
3.24 Tbit/s (81 WDM x 40 Gbit/s) carrier suppressed RZ (CS-RZ) format is simultaneously generated using a single supercontinuum source pumped by optically multiplexed 40 Gbit/s CS-RZ and is transmitted over 80 km link
C ryptogenic stroke (CS) accounts for up to one-third of cases of stroke or TIA. CS is defined as brain infarction not attributable to a source of definite cardioembolism, large artery atherosclerosis, or small artery disease despite extensive vascular, cardiac, and serologic evaluation. Patients with CS are heterogeneous by definition and the pathogenic mechanism of CS remains contested. Some ...
