Physical and radiopaque characterisation of acrylic bone cements containing an organobismuth compound as a radiopacifier

The water sorption and desorption characteristics of triphenyl bismuth (TPB)-cements were studied. The radiopacity of TPB was evaluated in order to assess its contrast in comparison to BaSO4-containing cements. It was observed that TPB-cements absorb/ desorp less water than BaSO4 cements (BS) due to the hydrophobic nature of TPB. It was shown that the addition of TPB to acrylic cements results in

A pilot study of problem solving in vector calculus using eye-tracking

Abstract in UndeterminedEye movements provide an online measure of the strategies students use to solve a problem. Such strategies are difficult to investigate with traditional methods of assessment. In this paper, we present some background and highlights of work in progress, aiming at a largerstudy where we will investigate how engineering students solve problems in vector calculus.

Theoretical study of electronic structure and optical properties of semiconductor nanostructures

In this thesis, the electronic structure and optical properties of semiconductor nanostructures are studied theoretically. Three types of nanostructures have been studied, silicon nanocrystals, free-standing III-V nanowires and free-standing GaAs/AlGaAs nanowire superlattices. The calculations have been carried out using an atomistic, empirical tight-binding approach. Silicon nanocrystals have at

Competition law in technology transfer under the Trips agreement

The TRIPS Agreement allows WTO members to appropriately enact and apply national competition law to address IPR-related anti-competitive practices. However, application of national competition law to anti-competitive restraints in technology transfer agreements and to abuses of refusal to transfer technology varies from developed countries to developing countries and even between developed countri

A quasi static iterative method for inductor parameter

A low frequency algorithm designated for the calculation of the magnetic and the electric energies and the ohmic losses of passive components has been developed. These quantities can be used to achieve the inductance, the capacitance, the resistance, and the Q-value of the inductor at low frequencies. The method is based on an iterative scheme in which the different fields, such as the electric po

Simulation of a design of a lab scale Radio frequency heating unit of hamburgers

With regard to efficient food processing and cost effective production lines, Radio Frequency (RF) heating is a prime example. Thermal processing of food has gained an ever growing importance as food manufactures strive after increasing the number and quality of value added products on the market. Solid food, such as meat and vegetables, is more difficult to heat efficiently since it cannot be pum
