Abstract

Nowdays, regarding to the great us of sensitive devices, the quality of the transmitted power, have become an important issue. One of the most important dimension of power quality is magnitude load terminal voltage. Different devices has been designed for voltage sag compensation or other distortions. UPQC is a compensator which is able to compensate all distortions, such as voltage sag, flicker, unbalance, harmonic and current distortions such as reactive, harmonic and unbalance. Several controllers have been designed to compensate the whole or a part of distortions. In this paper its going to introduce a kind of controller which is able to compensate voltage sag to direct and simple by UPQC. At the end, simulation and voltage sag mitigation is going to be performed by ATP-EMTP software.

Abstract

Zr-doped TiO2 nano photocatalyst obtained with a various trace amount of Zr, by using the sol-gel method. Several spectroscopic techniques applied to characterize the structures and properties of nano-photocatalyst. It founded that the effect of doping Zr ions to the TiO2 lattice led it to improve the surface properties and decreasing the particle size of nano-photocatalyst. Therefore, it causes increasing specific surface area and photocatalytic activity as compared with pure TiO2. The results revealed that there was an inverse relationship between the growth of the crystallite size of the nano photocatalyst and the decline of the molar ratios of Zr. The photocatalytic activity of the nano photocatalyst employed for the decolorization of Congo red as an Azo dye in the aqueous solution under UV irradiation in a batch reactor. The results exhibited that the TiO2/Zr0.0004 brings the best photocatalytic activity.

Abstract

The paper examines global research in big data, as covered in Scopus database 2007-16, on a series of bibliometric indicators. The study finds that big data registered exceedingly fast growth (135.2%), but averaged low citation impact per paper (3.75) and accounted for very low share of highly cited papers (0.86%) in 10 years. The study reports publication trends in big data research by top countries, top institutions, top authors, top journals, major subject areas, publication modes, and country-level share of international collaborative publications. The study concludes that big data is a subject of recent origin. Given its major potential to impact business, governance, society, healthcare, industry and many other sectors, big data is fast emerging as a major discipline of interest and importance to nations, corporates, and institutions across developed and fast emerging economies.

Abstract

Purpose: Angiogenesis is essential for tumor growth or metastasis. Avastin is a monoclonal antibody that is used in treating angiogenesis. We labelled this monoclonal antibody with samarium153 and performed in vitro quality control tests as a first step in the production of a new radiopharmaceutical.Material and Methods: For a successful radiolabeling, we chose DOTA-NHS as the bifunctional chelating agent and optimized radiolabeling condition with modifications of the factors such as reaction time and molar ratio which are known to be very critical in radiolabeling. The efficiency and in vitro stability of antibody labelling were determined using thin layer chromatography. The integrity of the radiolabeled antibody was checked by SDS-PAGE. Biodistribution study of 153Sm-DOTA –avastin was carried out in BALB/c mice at 2, 24, 48 and 72 hours after injection. Immunoreactivity and toxicity of the complex were tested on colon cancer cell line by MTT.Results: The efficiency of antibody labelling was more than 99%. The in vitro stability of the labelled product in human serum after 120h was 78 ±2%. There was no fragmentation in the labelled antibody during SDS-PAGE protocol. The highest of %ID/g was observed in the blood, liver, lungs and spleen. The immunoreactivity of the complex was 89±1.4%. At a concentration of 1 nM, the complex killed 70±3% of SW480 cells. At 1.9 nM, 90±5% of the cells were killed.Discussion: The monoclonal antibody avastin against angiogenesis was effectively radiolabeled with 153Sm. The results showed that the new complex could be considered a promising tracer for noninvasive delineation of angiogenesis.

Abstract

The main objective of this study is interpreting the probable dependency of structural performance level and its corresponding inter-story drift in conventional RC moment frames. For this purpose, inter-story drift as dependent variable and other structural characteristics such as strength of materials, structural dimensions and internal loads as independent variables have been assumed. Specimens were studied by means of pushover analysis, then independent and dependent variables have been recorded for each member. Correlation of all variables were examined extensively and finally accurate equations have been proposed to predict inter-story drift at performance objectives.
