The Norwegian Ferro-alloy Industry and the model for research cooperation between SINTEF, NTNU, and the Norwegian ferro-alloy industry is presented as an introduction. The research within pyrometallurgy is illustrated by examples from characterisation of Mn-ores and characterisation of carbon materials. Examples from…
The microencapsulation process in which the removal of the hydrophobic polymer solvent is achieved by evaporation has been widely reported in recent years for the preparation of microspheres based on biodegradable polymers. The purpose of our present study was to investigate the feasibility of prolonged delivery of a…
This paper gives an overview of creation of the RW Management System in the Russian Federation. This process includes three areas: legal requirements, participants and facilities. One of the important steps was the adoption by the Russian Government of the Federal Target Program “Nuclear and Radiation Safety for 2008…
This paper presents the development of a new method for verifying the mechanical integrity of the insulation of lowvoltage cables in order to ensure a quality installation and prevent potential arcing faults. The approach consists in injecting compressed air into the cable core and to observe the subsequent pressure v…
The kinetics of oxidation of a number of meta- and para- substituted phenols by isonicotinium dichromate(INDC) in the presence of oxalic acid in aqueous acetic acid medium have been investigated. The reaction is first order with respect to oxidant and substrate,but fractional order with respect to both [H + ] ion and…
This project concerns cemented carbides and the carbides that are formed when adding chromium. Cemented carbides are composites, often consisting of tungsten-carbide particles embedded in a cobalt-rich matrix, and are because of their extreme hardness used in for example cutting tools and drills. Chromium is sometimes…
When cold forged gear steel is carburized, fine precipitates of TiC prevent austenite grain from coarsening. While preventing grain from coarsening, these precipitates increase the deformation resistance against cold forging due to precipitation hardening. This study evaluates the influence of TiC precipitates on the…
Hyundai Engineering Company (HEC) signed a new contract with Korea Radioactive Waste Management Corporation (KRMC) to develop Low and Intermediate Level Radioactive Waste (LILW) transport system applicable to regular transportation of LILW from each Korean Nuclear Power Station to LILW disposal facility located in Gye…
The study of conical refraction for media other than biaxial non-magnetic crystals has never been considered in the literature – as far as the authors are aware. Hence, in this paper, we investigate how conical refraction can arise for broader classes of biaxial metamaterials using a new classification scheme previous…
In this work, nanocomposites were obtained by mixing an unsaturated polyester resin with a sodium montmorillonite slurry. Procedure by steps was clay slurry and polyester resin were stirring and subsequently monomer, initiator and catalyst were added to induce the cross-linking reaction. As comparative with pristine r…
Chromium Carbide composite coating has been the subject of interest in the area of nano material due to the improvement in mechanical properties when grain sizes reduce to nanometer scale.. Composite coating of chromium carbide has used in integrated printed circuit boards (PCBs), pins for dot-printers, corrosion resi…
Efforts are being made to increase the efficiency and decrease the cost of vitrifying radioactive waste stored in tanks at the US Department of Energy’s Hanford Site in Washington State. The compositions of acceptable and processable high-level waste (HLW) glasses need to be optimized to minimize the glass volume and,…
The rheological behaviour and morphology of in-reactor alloy of Polypropylene (PP)/Ethylene Propylene Rubber (EPR) synthesized by splitting the monomer feeding to copolymerization reactor are studied in this article. The Scanning Electron Microscopy (SEM) and oscillation rheometry were used to determine relationship b…
We propose the construction of a photocathode electron gun test facility for the characterisation of electron bunches emitted from a GaAs photocathode at room temperature and at LN2 (77 K) temperature, offering diagnostic capa- bilities to measure beam emittance and photocathode re- sponse time as a function of quantu…
Continuous monitoring of fluids in medical tubing is desired for point-of-care clinical diagnostics. In this work, we incorporate a nanostructured surface-enhanced Raman scattering (SERS) sensor into flexible tubing commonly used for intravenous drug delivery and urinary catheters. We investigate the detection of prom…
A pile foundation plays an important role in case of heavy lateral loads due to earthquakes, wind, wave etc. The pile caps which are often massive and deeply buried would be expected to provide significant resistance under the lateral loads. The few previous studies indicate that the lateral load resistance provided b…
This paper examines the efficacy and efficiency of the Waste Isolation Pilot Project (WIPP) of DOE with respect to the disposal of transuranic (TRU) waste. It will present an evaluation of the science, engineering, and operations management of WIPP starting from the pre-regulatory period and going through 2010. As WIP…
During exercise and in hot environments, the main cooling mechanism is through sweat evaporation. However, clothing can disrupt evaporation, which leads to decreased performance and in some cases can lead to heat illness. New fabrics and designs have been introduced with the purpose of improving thermoregulatory prope…
The present study addresses the relationship between the presence of some salts in crude oil and the corrosion of metallic equipments in the context of the petroleum refining industry. The rate of corrosion of iron in water containing CaCl2 and MgCl2 with concentrations similar to those in the water present in crude o…
The evaluation of uncertainties of radiological characteristics of low and intermediate level waste is a challenging issue for the global radioactive waste management community. One of the goals of ONDRAF/NIRAS as Belgian waste management agency is to propose a strategy that is applicable for all Belgian radioactive w…
