Real-time holographic interferometry has been used to visualize the evolution of the polarization layer during dead-end ultrafiltration of PEG-10000. Several experiments at a constant pressure of 1 bar and varying the feed concentration of PEG-10000 (5–12.5 kg/m3) have been carried…

In this paper we analyze a simple experiment to study the effects of polarized light. A simple optical system composed of a polarizer, a retarder (cellotape) and an analyzer is used to study the effect on the polarization state of…

The advent of performance metrics over the past two decades has heralded a cultural shift in
the way public service bodies and institutions have been managed. As a result, all public
service provision is now subjected to government led performance…

Discusses the debates raging around the content and delivery of business school education. Likens the current state to an organisational sickness, which needs to be
fully diagnosed before we can redesign our curricula.

Purpose: Businesses operate in a world facing a range of urgent global issues (UGIs). Unless an effective response is made in the near future, extremely damaging consequences are forecast. The purpose of this paper is to offer assistance to business…

Mixed-species foraging flocks were studied at Kichwa Tembo Camp on the edge the
Masia Mara National Reserve in Kenya between July and September 2004.
Observations were made on 29 mixed-species flocks, in which 24 species participated.
African Paradise Flycatcher Terpsiphone…

Background: There are many studies concerning the health consequences of intimate partner violence (IPV). However, little research has been done on the health consequences of other forms of violence against women (VAW) such as the violence perpetrated by male relatives,…

Silver halide sensitized gelatin (SHSG) is one of the most promising techniques for the fabrication of transmission holographic optical elements, achieving relatively high sensitivity of photographic material with the low scattering and high light stability of dichromated gelatin. In this…

We propose a two step method which enables us to obtain transmission Holographic Optical Elements of high diffraction efficiency as well as a good signal-to-noise relation. By means of a device using partially coherent light, a master Holographic Optical Element…

Equations are derived for determining third-order wavefront aberrations in the plane of the exit pupil from the known aberration in the plane of a holographic lens. Using the transformation equations of wavefront aberration when the plane of the exit pupil…
