Macromolecular Rapid Communications, EarlyView.Multidrug resistant Pseudomonas (P.) aeruginosa is detected in many infected wounds and is challenging to treat with antibiotics. As an alternative, this work incorporates anti‐P. aeruginosa Neko phages into electrospun fibres to explore their potential for treating infected wounds.

Similarity Assessment of the Engineering Concepts: Decision‐Making Support and Metrics
Systems Engineering, EarlyView.ABSTRACT The new product development (NPD) process is a systematic approach to bring new products and innovations to market. Nowadays, this process is affected by a number of influencing factors associated with the fast‐paced technological changes. One of those factors is the distributed design nature of product development activities: team members are

The Observatory, 1997 This thesis describes two studies of extragalactic radio sources at high resolution and sensitivity. Most of the well-known facts about radio sources come from low-resolution imaging, despite the fact that much of the interesting physics (that of the jets and hotspots) occurs on scales that are small compared to the overall source size.

Science Triggers and Situational Interest in Everyday Family Life
Journal of Research in Science Teaching, EarlyView.ABSTRACT Interest in science is critical for science learning. The family plays a major role in supporting the development of children's interest in science by eliciting and fostering interest and engagement with science content and practice. This study characterizes triggers for interest in science in everyday family life and measures the duration of ...

Discovery of Radio Jets in z ~ 2 Ultraluminous Infrared Galaxies with Deep 9.7 μm Silicate Absorption [PDF]
, 2007 Recent Spitzer observations have revealed a substantial population of z ~ 2 ultraluminous infrared galaxies (ULIRGs) with deep silicate absorption (τ9.7 > 1). This paper reports a 20 cm radio study of such a sample to elucidate their physical nature.

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).

Jet precession in active galaxies
The Astrophysical Journal, 1988 The formation and evolution of massive binary black holes in galactic nuclei are studied with respect to the loss-cone filling model for the fueling of massive black holes in AGN during the final stage of galaxy mergers. A relation between the precession period of the jet and the fueling rate of the central hole has been obtained.

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.

Numerical Simulations of Jets from Active Galactic Nuclei
Galaxies, 2019 Numerical simulations have been playing a crucial role in the understanding of jets from active galactic nuclei (AGN) since the advent of the first theoretical models for the inflation of giant double radio galaxies by continuous injection in the late ...
