During the current project phase of the disposal of category A waste – short-lived low and intermediate level waste – ONDRAF/NIRAS must, following the governmental decision of 23 June 2006, develop a near surface disposal facility in Dessel, which is based on the near surface facility disposal design developed by the…

In this paper, the residual electric field computation in a cable insulation in the presence of water trees and space charge is presented. Considering that, in treed areas, the variations of the permittivity and the space charge density are known, the thermal step current Ic(t) is computed and the curves Im (t) and Ic…
Whelks are carnivorous marine snails known for their elaborate and durable egg capsules. The mechanically complex capsules have been previously studied, and shown to have mechanical behaviour similar to keratin. The mature protein has an initial stiff linear elastic region at low strain, followed by a rubbery yield re…
Organic electronic devices have attracted increasing attention over the last decade. The use of organic materials allows the creation of large area, flexible and low-cost lightemitting devices, transistors and photovoltaics. The development of new organic materials contributes to a successful commercialisation. The pr…
In this investigation, the in vitro adsorption of tetracycline hydrochloride, neomycin sulfate, lincomycin hydrochloride, chloramphenicol, and ampicillin trihydrate by kaolin were studied. Adsorption studies were carried out at 37.0°C. in water and in pH 1.2, 3.0, and 5.0 solutions. The adsorption isotherms for tetrac…
Cortical spreading depression (SD) is a slowly propagating wave of brain cell depolarization that manifests in several neurological conditions, including migraine with aura, ischemia and brain trauma. The unique pattern of SD propagation suggests that it arises from an unusual form of intercellular communication. To a…
A final focus magnet design that uses super-ferric magnets is introduced for the Super-B interaction region. The baseline design has air-core super-conducting quadrupoles. This idea instead uses super-conducting wire in an iron yoke. The iron is in the shape of a Panofsky quadrupole and this allows for two quadrupoles…
Aerosol particles in the Earth’s atmosphere play a significant role in such aspects as health effects, visibility effects, and climate effects. In order to quantify the effects of aerosol particles, it is important to have a thorough understanding of the fundamental behavior of the particles. To address this issue, th…
This dissertation addresses the 3D flow through forming fabrics. In the first part of this thesis, the single phase 3D flow through certain specific fabrics was modeled. In practice, the Reynolds number of the fabric flow, based on paper-side filament diameter, is around 100. Consequently, it is not too surprising tha…
ABSTRACT Development of new green materials from by-products of animal rendering industries would provide a substantial economic return to animal rendering processors. Meat and bone meal (MBM), one of the products of the rendering industry, has potential for numerous bio-based applications. This research focuses on fa…

Bio-functionalized gold nanoparticles (Au-nps) are among the most attractive nanomaterials and are widely used in nanotechnology and biomedical science. They were intensively studied as versatile reporters and carriers in developing molecular diagnostic methods, regulating intracellular gene expression, as well as bui…
A study is made of the simultaneous heat and mass transfer processes which occur within a finite wood cylinder of circular cross-section when it is convectively dried. Governing transport equations are developed allowing for the functional dependence of both thermal and moisture diffusivities on moisture content and t…
Organic semiconductors have been the subject of intense scientific investigation for the past 50 years. Due to often weak bonding between organic molecules in the solid state, they share many of the properties of both semiconductors and insulators. Applications of \nthese materials include chemical, physical and biolo…
In this thesis, the corrosion properties of electrodeposited nanocrystalline Co and Co- 1.1 and 2.1 wt% P alloys (7 to 20 nm grain size) were investigated in a wide range of solution pH by using polarization and electrochemical impedance spectroscopy techniques along with scanning electron microscopy, energy dispersiv…
Semiconductors represent the enabling technology that underpins the many advances that define modern society. One semiconductor that shows considerable promise in the fabrication of new devices is zinc oxide (ZnO). A fundamental understanding of the properties of a material is required in order to exploit its properti…
There is a vital need to reduce enzyme costs to facilitate production of cost-competitive cellulosic ethanol and other products. End-product inhibition, declining substrate reactivity, enzyme denaturation, and non-productive binding of enzyme to lignin are among the factors that could account for the loss of enzyme ef…
A mathematical model to predict the through-thickness temperature distribution in a steel strip during hot rolling in the finishing stands has been developed. The model is based on one-dimensional heat conduction within the strip and the work rolls and takes into account the cooling due to descaler sprays, roll chilli…
This paper attempts to develop a technical feature of ancient Peruvian fabrics as a dating tool by describing its occurrence as fully as possible. The fabrics in this study share a common technique or method of manufacture which has been called "sprang". Sprang is a weftless technique of interworking a set of parallel…
