Cet article présente les modélisations effectuées par Egis Géotechnique dans le cadre du concours de prévisions concernant le comportement mécanique d’un ouvrage en Terre Armée. Pour évaluer à la fois les déformations de l’ouvrage ainsi que les efforts de tractions dans les armatures, une approche continue tridimensio…
When invented approximately thirty years ago, gear honing was (only) a surface polishing process with small materials removal rate. Up until a few years ago, the industry thought that even the large gears (diameter up to 280 mm), crank shafts, gears with collision contours necessitating the use of small cross axis ang…
A series of novel, 2,1,3-benzothiadiazole-based oligomers were synthesized by the self/cross-coupling reaction of monobromo-substituted benzothiadiazole compounds in a catalyst system comprising Pd(OAc)(2)/PEG (polyethylene glycol)/DMF The oligomers displayed good linear correlation between E-g(opt) (or lambda(max), (…
Simone Bartels, Erika Nowak and Tobias Richter Corrosive findings ascribed to Microbially Influenced Corrosion (MIC), have been increasingly observed on cooling water systems in Northern German nuclear power plants. By means of a research programme (field tests), high-alloyed materials with different Pitting Resistanc…
Les frigoporteurs diphasiques sont une technologie prometteuse. Une meilleure comprehension des cinetiques de cristallisation peut contribuer a la conception de generateurs performants. L’objectif de ces travaux est d’y participer. Une revue des theories classiques de nucleation et des modeles de cinetique de cristall…
Nonlinear analysis of a space frame subjected to loading from dropped objects UiS SummaryThere is always a risk of an object being dropped during offshore lifting operations.Any underlying structure or equipment might be severely damaged, and in worst case, lives might be lost.Consequently, structures which might be s…
Austenitic stainless steels specimens were deformed by tension from 0.03 to 0.12 of true strain at -50oC and -10oC, in order to obtain different volumetric fractions of e and a’ strain induced martensites. The morphology, distribution and volumetric fractions of the strain induced martensites were characterized by met…
This thesis tested the hypothesis that the inadequate tumor delivery of anticancer agents and selectivity of PGP modulation are primarily responsible for the attenuated therapy of extravascular MDR solid tumors overexpressing PGP. PSC 833 was selected as the MDR modulator for in vivo applications, based on potency, ex…
The temperature dependence of heat capacity C o = f(T) of fullerene derivative (t-Bu)12C60 has been measured by a adiabatic vacuum calorimeter over the temperature range T = 6–350 K and by a differential scanning calorimeter over the temperature range T = 330–420 K for the first time. The low-temperature (T ≤ 50 K) de…
Aerosols have in recent years been given increased attention due to their effects on climate and health. Drastic reductions in sulphur emissions in Europe during the last two decades have led to a larger relative importance of nitrate aerosols. However, large uncertainties still exist in the representation of nitrate…
This WTEC panel report assesses the international research and development activities in the field of catalysis by nanostructured materials. Catalysis is important for a wide variety of processes that impact manufacturing, energy conversion, and environmental protection. This study focused specifically on solid cataly…
For over a decade, the kraft pulp and paper industry has been challenged to find bleaching sequences that produce bright, high quality pulp without causing detrimental effects on the receiving environment. Historically kraft pulp was bleached with elemental chlorine and other chlorine containing compounds. However, af…
TYÖN TARKOITUS: Tämän diplomityön tarkoituksena oli valmistaa ja karakterisoida superhydrofobinen pinnoite sekä arvioida solujen ja bakteerien vastetta tälle pinnoitteelle, perustuen hypoteesiin, jonka mukaan superhydrofobinen pinnoite vähentää bioadheesiota tai estää sen täysin. MATERIAALIT JA MENETELMÄT: Lasi- ja ti…
Most of the work performed in this study has concentrated on the thermal decomposition of biomass. This was done because to the simple fact that biomass is mainly composed of volatiles that evaporates prior to the gasification stage.\n\nThe characteristics of the devolatilized products during pyrolysis are reported in…
Next I would like to thank my co-supervisor Yuri Galperin for advice and ideas, for answering all my e-mail requests despite the busy calendar, and for always being helpful and encouraging.I'd also like to thank Martin Kirkengen for including me in the Coulomb Glass project, for developing the simulation programme, sh…
The article focuses on disproof of the claim by Valery Ziuganov, that pearl oyster infection prolongs the lifespan of salmon and that pearl oyster can be used as a source of medicine. His activity on the production of medicine pretending to care cancer and senescence based on the gills of salmon infected by pearl oyst…
Non-specific protein adsorption is known to influence many processes. For example, fouling of food processing equipment or fouling of biomedical implants often occurs because of strong protein adsorption. Protein adsorption on these and other surfaces, such as biomaterials, can however be reduced by attaching polymer…
The title mixed-metal complex, {(NH4)(2)[Cu(C7H3NO4)(2)(H2O)(2)][CdCu(C7H3NO4)(2)(H2O)(6)]center dot 6H(2)O}(n), contains one octahedrally coordinated Cd-II center and two octahedrally coordinated Cu-II centers, each lying on an inversion center. The two Cu-II atoms are each coordinated by two O atoms and two N atoms…
Fe-doped (La, Sr)CrO(3-delta) (LSCrFe) oxide was modified as the anode of solid oxide fuel cells. Through vacuum-assisted impregnation processes, nanosized Sm-doped CeO(2) (SDC) and Ni particles were introduced into an anode backbone. With Ni and SDC coimpregnated LSCrFe anodes, the maximum power densities at 900 degr…
Palladium (0) nanoparticles incorporated hydrogenated amorphous carbon (Pd/a-C:H) films were synthesized on single crystal silicon (100) substrates by electrochemical deposition route using methanol and camphor as carbon source, and Pd nanoparticles as dopant. The characterization results indicate that Pd nanocrystalli…
