Purpose: The study aims to focus on rotation effects on a ribbed channel of gas turbine blades for internal cooling. The combination and interaction between secondary flows generated by angled rib geometry and Coriolis forces in the rotating channel are studied numerically. Design/methodology/approach: A radially outward flow passage as an internal cooling test model with and without ribs is used

Zlokazov and Utyonkov (2017 J. Phys. G: Nucl. Part. Phys. 44 075107) question the validity of the methods and conclusions presented by Forsberg et al (2016 Nucl. Phys. A 953 117). In this comment, we argue that the criticism is invalid.

A CW-laser radar system developed for combustion diagnostics is described. The system is based on triangulation to attain range information. A portable system has been constructed and here we show some result from measurements in various flames, for example Rayleigh scattering thermometry and monitoring of particle distributions with high temporal and spatial resolution. The concept can equally we

The concept of membrane separation is widely established in nature using semi-permeable membranes for the separation of molecules. The theoretical foundations of membrane technology can be dated back to 1748, when Nollet discovered the effect of “osmosis” in relation to natural membranes, while Graham in 1833 developed the solution-diffusion model for diffusion of gases through semi-permeable memb

Standardization, auditing, and performance measurement increasingly characterize the governance of professional organizations. In hospital services, this is expressed in a multiplication of quality as- surance programmes, which may be characterized as technologies of quality control. Organizational research shows that the impact of such technologies is profound and often problematic. Even if roote

Unhealthy food in advertising has been suggested as a mediator for the increase in diet-related illness. This study quantitatively investigates changes in food advertising between 1995 and 2014 in terms of food categories promoted, macronutrient content, and percentage of foods classified as heathy or unhealthy from a sample of 7,199 ads from three Swedish food magazines. With the exception of inc

Some of the most important challenges in teaching Intelligence Analysis in anacademic context are to make the students reflect on their own biases and toconvey how group dynamics shape the analytical process. Only by learningthis can they understand the ease with which an individual or group slips intofamiliar patterns of thinking and thus fails to identify new, unexpecteddevelopments. According t

The mission of the Swedish government’s National Commission on Substance Abuse was to analyze the access to substance abuse treatment and to clarify the division of responsibilities between health care and social services. As a part of this assignment a special analysis was performed on commitment to involuntary care. Involuntary commitment due to substance abuse has during many years been regulat

West Greenlandic Inuit Eskimo intonation has been described previously at word, phrase, and sentence levels (Mase 1973, Rischel 1974, Nagano-Madsen 1992, 1993). The present study attempts to extend the previous descriptions of intonation in this language by analysing text reading material, with focus on the phrasing function of intonation. The phrasing function of intonation has received much atte
