The new millennium began with two major nuclear decisions by the Parliament of Finland. In May 2001 the Parliament ratified the Decision-in-Principle (DiP) concerning the final disposal repository for spent nuclear fuel (SNF). One year later, in May 2002, it voted for the construction of a new nuclear power plant (NPP…
This paper examines the possibility of creating novel microwave frequency antennas by suitably arranging\nmetallic / dielectric nanoparticles. Simulation results show that the antenna must be composed of ≥ 99% metal (<1 % gaps).
The successful use of the McCad interface program for the conversion of CAD (CATIA) geometry data into MCNP 3D models is demonstrated. McCad was first tested on the example of an octant of the JET fusion device and then thoroughly benchmarked against other comparable approaches for a full size 40° torus sector of ITER…
Objective: In this paper,the chemical constituents and pharmacological activities of Marsdenia tenacissima had been reviewed to provide the reference for its further research.The constituents of Marsdenia tenacissima include C21 steroids,triterpenoids,organic acids,sterols,polysaccharide,and so on.Marsdenia tenacissim…
Individual classes of nanoparticles have made a tremendous impact on the biomedical sciences, with advances in imaging, single-molecule tracking, and cellular mechanotransduction. However, the future of nanotechnology will probably depend on the combination of attributes from several different nanomaterials. Here, one…
We have studied the FET device characteristics of the thiophene/phenylene co-oligomers chosen as organic semiconductors. The FET devices were made of two kinds of co-oligomer materials with different morphologies (i.e., the thin film and crystal). We show different device fabrication procedures depending upon the diff…
The aim of the Pro-ESR project is to design, construct and operate a state-of-the-art fixed energy electrostatic storage ring that will allow for precision experiments with most different kinds of ions in the energy range of up to 30 keV at the National Center for Mathematic and Physics (NCMP) at the King Abdulaziz Ci…
Padina minor Yamada, a brown alga which is found to be abundant on both sides of the coastal area of the gulf of Thailand and the Andaman Sea was examined for gastroprotective activity. The aqueous extract of P. minor (Aq. P) given orally to rats at the doses of 100, 200 and 500 mg/kg significantly inhibited gastric u…
Article A Micromechanical Constitutive Model for Concrete Subjected to Impact Loadings was published on August 1, 2009 in the journal International Journal of Nonlinear Sciences and Numerical Simulation (volume 10, issue 8).
The tribological behaviour of Stellite 6, Tribaloy 700 and Tribaloy 400C have been studied during self-mated unlubricated rotational sliding between 20 to 600°C, at 3ms−1 for 1 hour using scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX). Testing was conducted using a specially designed wea…
AbstrAct Purpose: The aim of the present paper was to elaborate deposition conditions of the DLC films prepared by magnetron sputtering technique. Design/methodology/approach: DLC layers were fabricated by the reactive pulsed magnetron sputtering method in the mixture of Ar and methane (CH 4 ). The gas pressure during…
Summary: For several years the “Centre d’Etudes de Gramat (CEG)” has been studying the behaviour of materials by means of experimental devices using High Pulsed Powers technologies. Among them, GEPI is a pulsed power generator devoted to ramp wave (quasi isentropic) compression experiment in the 1 GPa to 100 GPa press…
Wood fibre reinforced polylactic acid (PLA) composite foams have been successfully produced using supercritical carbon dioxide. A significant increase of specific properties, both stiffness and strength, was achieved by adding 5-10 wt% wood fibres. The experimental stiffness was comparable with a superposed micromecha…
The Hybrid Stress Blasting Model (HSBM) is a numerical blast modelling framework which links an ideal and non-ideal detonation code to a geomechanical rock model. The particle flow code originally implemented in the geomechanical rock model (PFC3D) has now been replaced by a lattice scheme. Results from controlled bla…
The structural properties of a quasicrystal model with twelve-fold rotational symmetry are studied. We correct the errors in the self-similar transformation of the square-rhombus-hexagon tiling model proposed by Socolar. Based on the Stampfli-Ghler square-rhombus-triangle tiling model， the quasi-unit cell is successf…
The large-scale iodine test Iod-9 of the German THAI programme was jointly interpreted by means of post-test analyses within the THAI Circle of the SARNET/WP16. In this test, molecular iodine (I2) was injected into the vessel dome of the 60 m3 THAI vessel to observe the evolution of its distribution between water, gas…
Metallic nanorods synthesized by oblique angle deposition on glass substrate are utilized as nano-scale structures that can be coated with SERS active metal to allow for excitation of surface plasmons. The synthesized nanorods have an average length of ~500-600 nm and are randomly distributed on the substrate. The SER…
It is generally desirable to reduce yarn hairiness as much as possible since it causes serious problems in both yarn production and use of yarn in subsequent textile operations. On the other hand, the cost of yarn production should be minimised while satisfying yarn hairiness and yarn strength specifications. In this…
Computer simulation of the pneumatic melt spinning of isotactic polypropylene based on the mathematical model of the process is presented. Two dynamic zones of the air jet-filament interactions along the melt blowing axis are predicted – a zone with a drawing activity of the air jets with aligned filaments in this zon…
Surface plasmons（SPs） generated in nano metallic gratings on medium layer can greatly enhance the transmission field through the metallic gratings. The enhancement effect is achieved from λ=500 nm to near-infrared domain. The enhancement rate is about 110% at the wavelength of about 610 nm and about 180% at λ=700 nm a…
