This paper presents the design of RT-Appia, a framework for the development and implementation of configurable real-time protocol stacks. The goal of RT-Appia is to allow the construction of specialized protocols through the composition of pre-defined micro-protocols. RT-Appia attempts to balance the flexibility and efficiency of micro-protocols with the predictability requirements of real-time...

composites with micro- and nano-metal fillers has attracted the attention of researchers for radiation shielding applications. Lead toxicity and heaviness have oriented extensive research toward the use of non-lead composite shields. The present study aimed to systematically review the efficiency of the composite shields of various micro- and nano-sized materials as composite shields have been ...

Recently established techniques for performing in vivo micro-computed tomography (micro-CT) provide the capability of monitoring bone changes in a living animal at various points in time. However, radiation exposure from repeated micro-CT scans may have an effect on skeletal growth in normal or disease-model animals. The purpose of this study is to test a high resolution (approximately 10 micro...

The functionality and efficiency of micro mobility schemes in wireless networks has a great impact on the overall performance of the whole network. In small cell wireless LAN environments, the network must support both frequent and numerous handovers at the same time. Together with providing fast and reliable handoffs, the micro mobility scheme must not affect the service perceived by users. Th...

Introduction: 192Ir is one of the important sources frequently used in brachytherapy. Up to now, a lot of commercial models of this source have been made which Ir-192 has been recently added to them. The aim of the present study is to determine the dosimetric parameters of this new source model based on the recommendations of TG-43(U1) protocol using Monte Carlo simulation tech...

STUDY OBJECTIVE s: To compare the effect of 4 weeks of treatment with fluticasone propionate (FP), 100 micro g bid, delivered either via the Diskhaler (GlaxoSmithKline; Middlesex, UK) or a hydrofluoroalkane (HFA)-134a pressurized metered-dose inhaler (pMDI) on airway responsiveness. DESIGN A single-center, randomized, double-blind, double-dummy, placebo-controlled crossover study. SETTING O...

BACKGROUND AND OBJECTIVE Computed tomography angiography plays a major role in the diagnosis of pulmonary embolism. Radiation dose associated with it is a major concern; therefore it is important to optimize protocols and techniques to ensure minimum radiation dose. METHODS The study compares two protocols i. Conventional Timing Bolus CT protocol and Delayed Timing Bolus protocol used to assi...
