The attenuation ability of composites containing micro and nano-sized WO3 was measured and compared with the attenuation ability of composites containing micro-size and nano-sized PbO for X-rays in diagnostic energy range. For the purpose, after synthesizing nano and micro-scaled particles, different percentages of them were imbedded in poly vinyl chloride (EPVC) emulsion and prepared as shield...
Background and purpose: Dose calculations in trachea HDR brachytherapy treatment planning systems are greatly based on TG-43 protocol in which, all materials including air inside trachea are treated the same as water. The aim of this study was to survey the effect of air on dose calculations of Flexiplan treatment planning system in trachea HDR brachytherapy. Materials and methods: To ev...
In rodent models of inflammatory arthritis, bone erosion has been non-invasively assessed by micro-computed tomography (micro-CT). However, non-invasive assessments of paw swelling (oedema) are still based on clinical grading by visual evaluation, or measurements by callipers, not always reliable for the tiny mouse paws. The aim of this work was to demonstrate a novel straightforward 3D micro-C...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
BACKGROUND & OBJECTIVES The optimal anti-snake venom (ASV) dose required to treat neurotoxic snake envenomation is not known. Low-dose ASV (national protocol: maximum dose 200 ml) may be as efficacious as the conventional regimen (100 ml six hourly till all symptoms disappear), but a direct comparison of the regimens is not available. The aim of this study was to test the efficacy of low-dose A...
Introduction: Polycystic ovary syndrome(PCOS) is one of the most common cause of infertility in women. clomiphene is the first line of treatment. however 20% of patients are resistant to clomiphene. because of follicular hypersensitivity to gonadotropins in pcod, multiple follicular growth and development occurs which is cause of OHSS and multiple pregnancy. Our aim of this random and clinical ...
The actual trend in the transport industry is to have electronic systems without mechanical back-up, so-called ”bywire” systems. Micro-computers control steering, brakes, power train etc... Robust protocols are needed to make these micro-computers communicate. They should be faulttolerant and yet not let the micro-computers split into disjoint communicating subsets. TTP is a time-triggered prot...
INTRODUCTION The aim of the study was to compare the success rate of an uptake-related ablation protocol in which the dose depends on an I-131 24-h neck uptake measurement and a fixed-dose ablation protocol in which the dose depends on tumour stage. METHODS All differentiated thyroid carcinoma patients with M0 disease who had undergone (near-) total thyroidectomy followed by I-131 ablation we...
One of the main issues with Mobile Internet Protocol (MIP) is slow handovers. Mobility protocols are classified as micro or macro depending on the domain of the network. When macro mobility protocols are used in managing localized mobility requirements, they result in slow handovers and delays that result in loss of packets and make these protocols unsuitable for time sensitive applications. Mi...
