This paper presents a data-driven approach to the construction of mapping models relating sound features and blowing pressure in recorder playing. Blowing pressure and sound feature data are synchronously obtained from real performance: blowing pressure is measured by means of a piezoelectric transducer inserted into the mouth piece of a modified recorder, while produced sound is acquired using...

Advocacy has been an inherent component of social work since the mid-1800s. The NASW Code of Ethics explicitly promotes advocacy as an ethical stance against inhumane conditions. Whistle-blowing, on the other hand, occurs mostly in the business and public administration disciplines and is relatively unknown in the social work profession. Using facts from composite cases of whistle-blowing incid...

A powder metallurgy route to the fabrication of metallic glass foam is introduced. The method involves consolidating metallic glass powder blended with blowing agent particulates to produce expandable precursors, capable of yielding foams with porosities as high as 86%. The foams are found to inherit the strength of the parent metallic glass, and to be able to deform heavily toward full densifi...

AIM The aim of this paper is to reveal the experiences and meaning of confidentiality for Australian nurses in the context of whistle blowing. BACKGROUND Despite the ethical, legal and moral importance of confidentiality within the health-care context, little work has addressed the implications of confidentially related to whistle-blowing events. METHODS The study used qualitative narrative...

Apart from density and alloy composition, the structure of solid metallic foams determines their mechanical performance. Herein, effect ambient pressure on foaming behavior AlSi6Cu4 precursors is studied. In situ X-ray radioscopy applied while in a furnace chamber pressurized up to 40 bar. The content blowing agent (TiH2) varied for each pressures chosen. foam morphology are analyzed quantitati...
