Abstract We study normal reflection subgroups of complex groups. Our approach leads to a refinement theorem Orlik and Solomon the effect that generating function for fixed-space dimension over group is product linear factors involving generalised exponents. gives uniform proof generalisation recent second author.

Do we really know what critical reflection means in the context of work-integrated learning, more specifically cooperative education? Critical reflection, in some form, is located within many higher education programmes, including cooperative education and many educators would say this is important for in-depth student learning. It is a form of reflection that is complicated as well as challeng...

Relative diffuse reflection measurements from the original and ground surfaces using a He-Ne laser are reported. The intensity measurements for the metallic, transparent dielectric, matte plastic surfaces and colored papers are presented. Our results indicate that among metallic surfaces tested, aluminum has the highest diffuse reflectance; while the original stainless steel surface shows the l...

In this paper metal-assisted chemical etching has been applied to pattern porous silicon regions and silicon nanohole arrays in submicron period simply by using positive photoresist as a mask layer. In order to define silicon nanostructures, Metal-assisted chemical etching (MaCE) was carried out with silver catalyst. Provided solution (or materiel) in combination with laser interference lithogr...

ince many applications rely on the knowledge of the electromagnetic material properties of ferrites, such as ferrite phase shifters, this paper presents an algorithm for characterizing ferrite materials in a single frequency using a rectangular waveguide system. In this method, the extraction of ferrite parameters is implemented through minimizing the difference between the measured data and th...

Many philosophers have worried about what philosophy is. Often they have looked for answers by considering what it is that philosophers do. Given the diversity of topics and methods found in philosophy, however, we propose a different approach. In this article we consider the philosophical temperament, asking an alternative question: What are philosophers like? Our answer is that one important ...

introduction: the phenomenon of knowledge explosion has led teachers to feel the necessity of training students so that they become reflective thinkers. this issue is more important for nursing students who are responsible for providing care for patients.this study is a part of another study arming at exploration of nursing students’ views on reflection on practice. methods. 20 senior nursing s...
