Interacting galaxies in the NGC 697 group of galaxies [PDF]
Proceedings of the International Astronomical Union, 2016 AbstractWe studied the morphology of two brightest members of the nearby NGC 697 group of galaxies, and found evidence of satellite accretion onto the primary galaxy NGC 697 of the group as well as outer and inner irregularities of the only early-type galaxy NGC 680 of the group, which are probably shaped by recent dry merging event(s).

Small, EarlyView.Nano‐pulling induces stabilization, reorganization, and reorientation of the microtubule network. The nucleus of stretched cells experiences increased lateral tension, becomes more spherical, and develops surface grooves. At the level of gene expression regulation, changes in nuclear morphology induce global chromatin remodeling, leading to reduced ...

Quantifying the FIR interaction enhancement in paired galaxies [PDF]
The Catalog of Isolated Pairs of Galaxies in the Northern Hemisphere, by Karachentsev (1972), was studied and a well-matched comparison sample taken from the Catalog of Isolated Galaxies, by Karachentseva (1973), in order to quantify the enhanced FIR ...

A Method for the Quality‐Aware Automated Selection of Deployment Technologies
Software: Practice and Experience, EarlyView.ABSTRACT Domain The deployment of distributed multi‐component cloud applications typically requires a combination of multiple heterogeneous deployment technologies. A different combination of deployment technologies should be chosen due to varying deployment qualities, such as the functional suitability and reliability of the deployment technologies ...

FIR statistics of paired galaxies [PDF]
Much progress has been made in understanding the effects of interaction on galaxies (see reviews in this volume by Heckman and Kennicutt). Evidence for enhanced emission from galaxies in pairs first emerged in the radio (Sulentic 1976) and optical ...

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK
Journal of Research in Science Teaching, EarlyView.ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

Properties of bars in the local universe
, 2008 We studied the fraction and properties of bars in a sample of about 3000 galaxies extracted from SDSS-DR5. This represents a volume limited sample with galaxies located between redshift 0.01-20, and inclination i < 60.

The Effect of Seductive Details on Knowledge Retention in Physics Videos: A Mixed Methods Study
Journal of Research in Science Teaching, EarlyView.ABSTRACT Research reports that interesting but irrelevant information, seductive details, in teaching material can impede learning. In science education, the inclusion of historical narratives in lessons to promote interest has been recommended but may hinder learning.

High Voltage, EarlyView.ABSTRACT This paper investigates the effects of radiation on polymeric materials used as insulation systems in electrical equipment such as cables for nuclear and particle accelerator applications. After a detailed description of the physics of radiation‐induced damage in the polymeric matrix, a comprehensive analysis of the physical–chemical and ...
