Due to the demands for energy saving and environmental conservation, the development of sustainable zero-carbon buildings has become an inevitable trend. Building Integrated Photovoltaics (BIPV) is a promising technology capable of producing clean electricity onsite and replacing conventional building materials. This paper designs and investigates the performance of a planar Lambertian reflecto...

The aim of this qualitative case study was to examine the use of reflective journals in promoting reflection and learning in post-registration nursing students. A purposive homogenous sample of 42 part-time post-registration students who had undertaken a module either as part of the Diploma in Professional Studies in Palliative Care or Breast Care Nursing within a UK University took part in the...

This paper reports on the design and implementation of thin film multilayer dielectric to form Bragg reflectors on the sidewalls of micromachined atomic cells. Due to deposition shadowing, significant variations in the thicknesses of the thin films are encountered when the layers are deposited using PECVD. These gradients in thickness may limit optical performance of the reflector in atomic cel...

Applying Bragg gratings in Al2O3 channel waveguides, we demonstrate distributed Bragg reflectors with Qfactors of 1.0210 6 . An integrated Al2O3:Yb 3+ waveguide laser with 67% slope efficiency and 47 mW output power is achieved with such cavities.

In an abstract category with suitable notions of subobject, closure and point, we discuss the separation axioms T0 and T1. Each of the arising subcategories is reflective. We give an iterative construction of the reflectors and present characteristic examples.
