The coevolution of galaxies and their central supermassive black holes is a subject intense research. A class objects, the dust-obscured (DOGs) are particularly interesting in this respect as they thought to represent short evolutionary phase when violent star formation activity host galaxy may coexist with matter accretion onto hole powering active nucleus. Here we investigate different types ...

In structural engineering, thin-walled structures play an important role in the design of lightweight model. It carries different loading conditions when it exists any model, and is designed with thin plates or shells. Penetrating kinds holes can decrease their weight facilitate repair maintenance operations, such as those carried out for wing airplane. applications, cutouts are often employed ...

introduction polymer gel dosimeters offer a practical solution to 3d dose verification for conventional radiotherapy as well as intensity-modulated and stereotactic radiotherapy. in this study, egsnrc calculated and pagat polymer gel dosimeter measured dose profiles from single shot irradiation with 18 mm collimator of gamma knife in homogeneous and inhomogeneous phantoms were compared with eac...

This study aims to determine the impact of COVID-19 outbreak on fine motor development children aged 3-4 years. Population and sample in were parents who had years, total population samples 28 parents. With details have years .. skills are movements that involve finer performed by small muscles. These subtle require careful coordination. The better so can be creative, such as cutting paper with...

The 3D-Drift And SHift (3D-DASH) program is a \textit{Hubble Space Telescope} WFC3 F160W imaging and G141 grism survey of the equatorial COSMOS field. 3D-DASH extends legacy HST near-infrared spectroscopy to degree-scale swaths sky, enabling identification study distant galaxies ($z>2$) that are rare or in short-lived phases galaxy evolution at rest-frame optical wavelengths. Furthermore, when ...

RATIONALE AND OBJECTIVES To examine the effectiveness and suitability of a quality control (QC) phantom for a routine QC program in digital radiography. MATERIALS AND METHODS The chest phantom consists of copper and aluminum cutouts arranged to resemble the appearance of a chest. Performance of the digital radiography (DR) system is evaluated using high and low contrast resolution objects pla...

Two types of cold plasma generating paper-based electrodes (CPPE) made with flexible metallized paper were developed to decontaminate fresh produce. As opposed conventional rigid volume dielectric barrier discharge currently used for in-package generation which voltage increases as a function thickness, two CPPE configurations based on surface provided high local concentrations less was indepen...

The aim: study of the effectiveness environmentally safe disinfectants against P. aeruginosa and pathogens main bacteriosis poultry at test facilities.
 Materials methods. To antimicrobial action investigated a mixture epizootic cultures E. coli, aeruginosa, S. aureus, typhimurium, isolated from poultry, bacteriological studies were carried out on objects: galvanized iron, wooden bars (pai...

Strongly lensed quadruply imaged quasars (quads) are extraordinary objects. They very rare in the sky -- only a few tens known to date and yet they provide unique information about wide range of topics, including expansion history composition Universe, distribution stars dark matter galaxies, host galaxies quasars, stellar initial mass function. Finding them astronomical images is classic "need...
