Σκοπός της μελέτης ήταν να καταδείξουμε τις ποσοτικές διαφορές του οξειδωτικού φορτίου ασθενούς με ΧΑΠ σταδίου Ι και ασθενούς με ΧΑΠ σταδίου Ι και ΣΔ ΙΙ. Ως βιοδείκτες χρησιμοποιήσαμε τη μαλονική διαλδεΰδη (MDA) και τις καρβονυλιωμένες πρωτεΐνες ορού (CP), καταγράφοντας τη λιπιδιακή υπεροξείδωση και την πρωτεϊνική καρ…
The dielectric performance of a fully cured non-VPI flexible stator coil insulation system was investigated by performing winding trials and series of dielectric tests. Different dielectric tests performed were voltage endurance (VE), surge test and thermal cycling. VE and thermal cycling tests are well understood and…
Abstract The possibility of edge regime transitions under the influence of edge‐localized modes (ELMs) is investigated. A theoretical model of the process is presented and examined numerically. ELMs appear able to trigger irreversible transitions from one equilibrium to another with different edge temperatures. The re…
Epitaxial growth of Ge films on Si substrates has been studied intensively because the properties of these films are promising for various kinds of applications, such as light emission in optoelectronic integrated circuits, a channel material in field-effect transistors, a material in high-speed optoelectronic devices…
Abstract Annually since 1989, biannually since 1994 the sites of the Swiss nuclear facilities (4 power plant sites, a nuclear research institute and a waste storage facility) are surveyed flying the same survey lines by airborne gamma ray spectrometry. The equipment and the data processing software used for those surv…
The potential of OpenFOAM to design extrusion dies, incorporating the Fluid Structure Interaction (FSI)
We review our efforts on using numerical simulations to study essential physics of dissipative quantum transport in nanoscale field-effect transistors (FETs). Three types of nanoscale transistors are modeled as examples, (i) graphene nanoribbon (GNR) FETs with a quasi-one-dimensional (1D) channel, (ii) graphene FETs w…
The effect of morphology on the stability of Cu2O remains a great challenge. We have synthesized two types of samples in cube crystal structure with about 700 nm by a facile reduction route, which were investigated by X-ray powder diffraction (XRD), Scanning Electron Microscopy (SEM), Energy- dispersive X-ray (EDX) an…
In this contribution, angle-resolved X-ray photoelectron spectroscopy is used to explore the extension and nature of a GaAs/GaInP heterointerface. This bilayer structure constitutes a very common interface in a multilayered III-V solar cell. Our results show a wide indium penetration into the GaAs layer, while phospho…
Electronic structures of silicon with carbon, indium, or indium-carbon dimers were calculated to investigate the interaction between indium and carbon in X center due to the indium-carbon dimers. Ab initio calculations were carried out mainly for basic Si71H60, C-Si70H60, In-Si70H60, and InC-Si69H60 clusters. The resu…
We report on direct formation of J-aggregates in cyanine dye solution by injection of colloidal CdTe quantum dots. The optical properties of formed J-aggregates have been investigated by absorption and photoluminescence spectroscopy and fluorescence lifetime imaging microscopy. Quantum dots/J-aggregate system shows th…
The galvanomagnetic properties in weak magnetic fields (4.2T300 K, B0.07 T) as well as Shubnikov-de Haas effect (T=4.2 K, B7 T) in the single crystal Pb1-x-ySnxVyTe (x=0.20, y0.01) under hydrostatic compression up to 15 kbar have been investigated. It is shown that under pressure the decrease of activation energy of v…
A review on the numerical studies about KE(kinetic energy) penetrator into concrete target with mass loss is presented. There are two main ways to study the mass loss in numerical simulation: finite-element method and abrasion iterative algorithm. For each method, detailed introduction is given at home and abroad. A s…
In this study polypropylene (PP) composites containing β-nucleating agent (NT-C) and talc filler were prepared by melt compounding. The melting and crystallization behavior, morphology and mechanical properties of the composites were studied by means of differential scanning calorimetry (DSC), wide angle X-ray diffrac…
Abstract The cover picture shows a simple route to generate MgO nanosheets from low‐cost magnesium acetate. Magnesium acetate is esterified into methyl acetate and Mg(OH)(OCH3) under mild solvothermal treatment in methanol. The Mg(OH)(OCH3) exhibits a sheet‐like morphology and can be topotactically transformed into Mg…
Traditionally materials like clay, sand, stone, gravels, cement, brick, block, tiles, distemper, paint, timber and steel are being used as major building components in construction sector. All these materials have been produced from the existing natural resources and will have intrinsic distinctiveness for damaging th…
Methanotrophic physiology is strongly affected by the amount of bioavailable copper, which regulates the enzymes used by methanotrophs to oxidize methane. Methanobactin is a small peptide secreted by methanotrophic bacteria that binds copper outside of the bacterial cell. In this study, gold nanoparticles were firstly…
We propose ion shower doping technique to fabricate selective emitter structure solar cells. This technique provides large beam area and therefore high through-put. We used the technique to form emitter layer and also selective emitter parts for solar cell devices. From the results, it was confirmed the good electrica…
PURPOSE: For flattening-filter free (FFF) photon beams, conventional algorithm based on equivalent-square to calculate dose per MU is invalid because of the non-uniform profile. In this study, an empirical algorithm is developed to calculate the dose accurately, which can be used for secondary MU check for IMRT using…
At high AC field strength, BH loop tends to twist slightly near the tip point. It results in apparent decrease of iron loss because the overturned parts introduce negative iron loss value. In order to correct this error the phase difference between flux density and magnetic field strength needs to be eliminated. We st…
