Suggesting an Appropriate Process for Image Management in IRIB

In a world where communication advances have overshadowed almost every issue in the world, the political components of power have also been affected. Today, in addition to diplomatic relations between governments, public diplomacy has emerged in various contexts, including the media environment and radio and television are one of the main opportunities through which purposeful image can be conveyed to the audience using the concepts of image management. In fact, the ultimate goal of the image management process is to create and present purposeful image of people, events and topics which are appropriate with the aims of a media and to transfer deliberate and proper images to audiences using image management strategies. By adopting the process approach and use of the in-depth interview method, this study tried to identify the leverage that change this process based on Kondor reengineering and suggest an appropriate process for image management in IRIB. For this purpose, the findings of the interview with twenty experts, professors and communication researchers and a number of managers and consultants of IRIB were coded and categorized. Then by using iMindamp software, 220 extracted concepts were reduced to 20 concepts and finally the model of image management process formed. The model consists of six support systems and four main systems that in systematic view form the proposed image management process in the IRIB

Experimental Determination of the Temperature Suppression in Formation of Gas Hydrate in Water Based Drilling Mud

The aqueous mixtures of light gas molecules under low-temperature and high-pressure conditions are candidates to form gas hydrate clathrates. The formation of gas hydrate may lead to various problems and extra charges in natural gas production and processing. The presence of hydrate crystals forming a stable solid phase can potentially block the wells, pipes, and process facilities. To avoid such problems, hydrate formation must be studied in different conditions. In this regard, this study aims to design an experimental procedure to determine gas hydrate formation in water based drilling mud. In addition to this, the effect of different inhibitors (i.e. NaCl, methanol, and ethylene glycol) on the hydrate temperature suppression is studied. The designed apparatus is capable of determining hydrate formation conditions in both static and dynamic conditions. Based on the obtained results, among the combinations of NaCl with methanol or ethylene glycol at different concentrations, a mixture of 10 wt.% NaCl + 10 wt.% methanol shows the best inhibition effects (i.e. higher temperature suppression and longer induction time). Furthermore, the experimentally obtained temperature suppression data were fitted and compared against two different thermodynamic models. Temperature suppression variation with inhibitor concentration is described in an acceptable manner by both models.The present contribution is aimed to design an experimental procedure to determine gas hydrate formation in water based drilling mud.

Churg-Strauss syndrome following cessation of allergic desensitization vaccination: a case report

<p>Abstract</p> <p>Introduction</p> <p>Churg-Strauss syndrome is a vasculitis of medium to small sized vessels. Diagnosis is mainly clinical with findings of asthma, eosinophilia, rhinosinusitis and signs of vasculitis in major organs.</p> <p>Case presentation</p> <p>We present a case of a 19-year-old Persian male who developed signs and symptoms of this syndrome related to hyposensitization treatments for allergy control.</p> <p>Conclusions</p> <p>No unifying etiology for the disease can be presented as it is found associated with environmental factors, medications, infections and is even considered a variant of asthma with predisposition to vasculitic involvement. Therefore, it is important to recognize this disease and be aware of underdiagnosis because of emphasis on pathologic evidence. Here, we present a case of allergic desensitization causing Churg-Strauss syndrome in the absence of other known factors.</p

Determination of Rhodium(III) Ions by Flame Atomic Absorption Spectrometry after Preconcentration with Modified Magnetic Activated Carbon

A new method for analysis of trace amount of Rh(III) ions by magnetic activated carbon modified with 2,3,5,6-tetra(2-pyridyl)pyrazine (MAC/TPPZ) as the magnetic sorbent has been proposed. The proposed adsorbent was found to be advantageous over conventional solid phase extraction (SPE) in terms of operational simplicity and low time-consuming. The experimental parameters affecting the extraction/preconcentration and determination of the analyte were systematically examined. In order to investigate the selectivity of this magnetic sorbent, the effect of a variety of ions on preconcentration and recovery of Rh(III) ions were also investigated. Under optimum conditions, the calibration graph was linear for the concentration range of 0.8-650 µg l-1. The limit of detection (LOD, 3Sb/m) and the relative standard deviation (RSD, n = 8, c = 50 µg l-1) were 0.1 µg l-1 and 3.6%, respectively. The maximum sorption capacity of the adsorbent for rhodium was found to be 21.6 mg g-1. The presented procedure was applied to monitoring rhodium in water and synthetic samples

Removal of Dibenzothiophene Using Activated Carbon/γ-Fe2O3 Nano-Composite: Kinetic and Thermodynamic Investigation of the Removal Process

In the present study, removal of dibenzothiophene (DBT) from model oil (n-hexane) was investigated using magnetic activated carbon (MAC) nano-composite adsorbent. The synthesized nano-composite was characterized by FT-IR, FE-SEM, BET and VSM techniques. The MAC nano-composite exhibited a nearly superparamagnetic property with a saturation magnetization (Ms) of 29.2 emu g-1, which made it desirable for separation under an external magnetic field. The magnetic adsorbent afforded a maximum adsorption capacity of 38.0 mg DBT g-1 at the optimized conditions (adsorbent dose, 8 g l-1; contact time, 1 h; temperature, 25 °C). Langmuir, Freundlich and Temkin isotherm models were used to fit equilibrium data for MAC nano-composite. Adsorption process could be well described by the Langmuir model. Kinetic studies were carried out and showed the sorption kinetics of DBT was best described by a pseudo-second-order kinetic model. In addition, the MAC nano-composite exhibited good capability of recycling to adsorb DBT in gasoline deep desulfurization
