As the largest radio telescope in world, Square Kilometre Array (SKA) will lead next generation of astronomy. The feats engineering required to construct array be matched only by techniques developed exploit rich scientific value data. To drive forward development efficient and accurate analysis methods, we are designing a series data challenges that provide community with high-quality datasets for testing evaluating new techniques. In this paper present description results from first such...
We analyze the light curve of 1740 flare stars to study relationship between magnetic feature characteristics and identified activity. Coverage stability features are inspired by rotational modulation variations activity obtained using our automated detection algorithm. The results show that (i) Flare time occupation ratio (or frequency) total power flares increase increasing relative coverage contrast in F-M type (ii) Magnetic is highly correlated with structures as this case for Sun (iii)...
In this experimental work, we investigated the dynamic behaviour of transient holographic grating in an Azo dye doped nematic liquid crystal, formed by a pulsed laser. Relaxation was studied two geometries, when director is parallel or perpendicular to vector. time constants for different writing angles were used measure diffusion coefficients. The obtained results show anisotropic photo excited molecules.
We present an investigation of the magnetic activity and flare characteristics sub-giant stars mostly from F G spectral types compare results with main-sequence (MS) stars. The light curve 352 on branch (SGB) Kepler mission is analyzed in order to infer stability, relative coverage contrast structures also properties using three indexes. show that: (i) Relative features along rate, power magnitude flares increase SGB due deepening convective zone more vigorous field production (ii) Magnetic...
Abstract To deepen the analysis of photometric properties umbra a sunspot, we study proper motions small features such as umbral dots (UDs) inside single sunspot observed by Solar Optical Telescope Hinode close to disk center. We consider horizontal flows with high precision and details transient motion behavior UDs in short time intervals. Blue continuum images were first deconvolved point-spread function, that stray light is precisely removed original resolution improved. Several co-added...
Abstract Background Fever is the most common reason for children’s visits to medical centers. Its management an essential duty of a pediatric nurse. The aim this study was determine effect body wash with Marshmallow plant on fever. Methods This parallel clinical trial performed 92 children aged 6 months 10 years tympanic temperature above 38.3 °C. Participants were randomly assigned groups. Simultaneously receiving acetaminophen, in control group lukewarm water and intervention white...
Abstract A novel Deep Eutectic Solvent (ETPP-Br/THF-TCA-DES) was prepared by a mixture of ethyl triphenylphosphonium bromide (MTPP-Br) and tetrahydrofuran-2,3,4,5-tetra-carboxylic acid (THF-TCA, mole ratio 7:3) in cheap, simple, non-toxic method, characterized FT-IR, TGA/DTA, densitometer, eutectic point, 1 H NMR techniques used as capable new catalyst for the synthesis two sets compounds: i) four [a(1-4)] ten [a(5-15)] known alkyl...
This work deals with phase morphology in ternary blends of polypropylene (PP)/ polycarbonate (PC)/ poly (styrene-b-(ethyl- ene-co-butylene)-b-styrene) (SEBS) based on PP continuous and also its consequence tensile properties. Firstly, two types conceptual models have been employed to foresee the type interfacial tension polymer pairs. Scanning electron microscopy has used witness predicted morphology; however, relative energy model was only theoretical relation which agreed observed...
