Evaluation of charge storage ability of chrome doped Mn2O3 nanostructures derived by cathodic electrodeposition
No full textA facile synthetic route has been proposed to prepare cauliflower-like nanostructures of Cr doped Mn2O3. The synthesis was carried out by constant current cathodic electrodeposition from Mn2+ nitrate solutions containing minor amounts of dichromate. It was found that the presence of Cr mediates the formation of cathodic MnO2 which then reacts with the excess Mn2+ species to form Mn2O3 nanostructures. X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Differential Thermal Analysis (DTA) were used to characterize the nanostructures. The storage ability of the obtained nanostructures was investigated by cyclic voltammetry (CV) in 0.5 M Na2SO4 solution. The results indicated that the Cr doped manganese oxide material shows better performance than the non-doped one, and the charge capacity (SC) of doped manganese oxide (218 F/g) was higher than pure manganese oxide (208 F/g)

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Evaluation of OxPL Levels in Patients Undergoing Coronary Angiography: A Cross-Sectional Study
No full textBackground and Aim: Coronary ectasia is one of the prevalent cardiovascular diseases worldwide. It causes many deaths annually ranged between 9% to 10% which is dependent on related risk factors. The main pathogenesis has not been determined yet; however, it has been shown, that increased lipid profiles and their oxidation in patients can cause endothelial cell dysfunction and thrombosis. Therefore, here we investigated the oxidized phospholipids (OxPLs) role in the pathogenesis of coronary artery disease.
Methods: This cross-sectional study was performed in Shariati Hospital, Tehran. Accordingly, patients with coronary artery angiography indications (n=360) were included and classified into one of the following three groups, based on the angiographic results: 1) normal coronary artery (not dysfunction in vessels) or mild CAD (only intimal irregularity or less than 3% narrowing without ectasia); 2) vessel dilation more than 1.5 times compared to the normal part of the vessel or compared to the normal size according to age and gender in one or more coronary vessels; and 3) patients with more than 50% stenosis in one of the coronary arteries. The peripheral blood was collected from patients in EDTA anticoagulants container tubes and the OxPL level was measured using an ELISA kit.
Results: The results showed that the amount of OxPL in the third and second groups was higher than in the first group. It was also found that hyperlipidemia, diabetes, hypertension, and smoking were higher in the third and second groups; all mentioned findings were statistically significant (p-value <0.05).
Conclusion: According to the findings of this study, it was shown that an increase in OxPL in patients with coronary ectasia can be considered as a risk factor for disease progression; OxPL measurement can be used to identify high-risk individuals.

Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
