Using the second-order perturbation theory we have calculated the scattering assisted gain spectra in GaAs/AlGaAs superlattice under a strong applied electric field in the Wannier-Stark-Ladder (WSL) regime. Nonequilibrium distribution function of quasi-two-dimensional carriers localized in each WSL level and indirect optical transitions between neighboring WSL levels accompanied by the emission or

The book is a monographie about a wooden castle in east Jutland in Denmark. The castle existed in the 14:th cent and all kind of archaeological material is extremely well preserved. The excavation took place in 1905 and was made by the famos danish archeologist C.M. Smidt and his assistent Christian Axel Jensen. The work was finished in 1916 but first now after 90 years the report was written

Popular Abstract in Swedish Vilka samband finns mellan de förändringar som skett sedan 1879 i samhälle, journalistik och tidningstexter? Det är den övergripande frågan för denna avhandling. Svaren utgår från undersökningar av fem strejkbevakningar i tre dagstidningar 1879–1996. Strejkbevakningarna gäller Sundsvallsstrejken 1879, storstrejken 1909, Metallstrejken 1945, gruvstrejken 1969-70 och sjukThis dissertation deals with journalistic texts in the Swedish daily press. The strike event has been chosen to make comparisons of the same event over time possible. The press coverage of five major Swedish strikes is investigated: the strike of the sawmill workers in the Sundsvall area in 1879, the general strike in 1909, the strike of the metal workers in 1945, the strike of the miners in 1969-

The reactivity of the vascular wall to endothelin-1 (ET-1) is influenced by cholesterol, which is of possible importance for the progression of atherosclerosis. To elucidate signaling steps affected, the cholesterol acceptor methyl-ß-cyclodextrin (mßcd, 10 mmol/L) was used to manipulate membrane cholesterol and disrupt caveolae in intact rat arteries. In endothelium-denuded caudal artery, contract

Rapidly rotating Bose-Einstein condensates confined in anharmonic traps can exhibit a rich variety of vortex phases, including a vortex lattice, a vortex lattice with a hole, and a giant vortex. Using an augmented Thomas - Fermi variational approach to determine the ground state of the condensate in the rotating frame - valid for sufficiently strongly interacting condensates - we determine the tra

Most available methods for synthetic unit hydrograph (SUH) derivation involve manual, subjective fitting of a hydrograph through a few data points. Because of this tedious procedure, the generated unit hydrograph is often left unadjusted for unit runoff volume. During recent decades, use of probability distribution functions (pdfs) in developing SUH has received much attention because of its simil

Popular Abstract in Swedish Reformationens budskap brukar karakteriseras med hjälp av några "allena": Kristus allena, tron allena, nåden allena och Skriften allena. I denna studie undersöks hur Martin Chemnitz (1522-86) behandlar dessa teman och hur han sätter dem i relation till Augustinus teologi. Martin Chemnitz var en av de mest framstående evangeliska teologerna i generationen efter Martin LuAs a co-author of the Formula of Concord, Martin Chemnitz (1522-86) codified the sola scriptura principle of the Reformation, that the prophetic and apostolic Scriptures are the only rule for all Church doctrine. This principle is clearly expressed in Chemnitz' own theological treatises as well, but in his argumentation one is also confronted with an astonishing number of quotations from the Churc

The production of wrong sign charmed mesons b --> (D) over bar X-(s), D-(s) = (D-0, D+, D-s), is studied using the data collected by the DELPHI experiment in the years 1994 and 1995. Charmed mesons in Z --> b (b) over bar events are exclusively reconstructed by searching for the decays D-0 --> K(-)pi(+), D+ --> K(-)pi(+)pi(+) and D-s(+) --> phipi(+) --> K(+)K(-)pi(+). The wrong sign contribution i

Subcutaneous lymphatics in the lower leg were catheterized in the retrograde direction in 6 healthy male subjects. The catheter was connected to a pressure transducer, and pressure was measured during three stages of exercise including standing, tip-toeing, and running in place. Before the third stage, indomethacin (50mg) was given i.v. Rhythmic pressure waves were registered in each subject. Duri

In this study we investigated if smoking subjects with a normal or slightly decreased lung function differ in the lymphocyte pattern compared to never-smokers. In a group of 'healthy' smokers (n = 58) and never-smokers (n = 34) 60 years old, we investigated the lymphocyte pattern in both BAL (n = 30 and n = 18 respectively), bronchial epithelium and lamina propria (n = 14 and n = 10 respectively)

Symptomatic portal hypertension (PH), is often treated by transjugular intrahepatic portosystemic shunt (TIPS). Patients with PH, caused by prehepatic portal vein occlusion, require recanalization with stent or stent-graft often followed by additional TIPS. Stent-grafts used for TIPS, may occlude the outflow from the adjacent hepatic vein, potentially disturbing the circulation through the adjoini

The clinical features of delta infection were analysed retrospectively in 191 hepatitis B surface antigen (HBsAg) carriers and 592 cases of acute hepatitis B seen over 11 years in the Swedish town of Malmo (population 250 000). With a few exceptions delta infections occurred exclusively in drug addicts. In the chronic HBsAg-carriers the most common clinical manifestation was an episode of acute he

We have started a systematic investigation of the radiative properties of the elements of the sixth row of the periodic table. Using a combination of experimental radiative lifetimes obtained with the time-resolved laser-induced fluorescence (LIF) technique and of theoretical branching fractions (BF) calculated with a HFR approach taking configuration interaction and core-polarization effects into

We recently established a skin organ culture model for epithelial healing by creating a central defect in freshly excised human skin specimens and keeping them in culture for up to 7 days, either untreated or with transplantation of allogenic or autologous keratinocytes. In this study the molecular diversity of cell-cell junction proteins in the regenerating epidermis was analysed immunohistochemi

By combining recent level crossing data with the results from a modified atomic beam experiment by Buck, Rabi, and Senitzky in 1956, a Landégj factor deviating about 0.6% from the LS-value -1.3341 is obtained for the 6p2P3/2 level of Cs133. As this large deviation is difficult to explain, a remeasurement of the hyperfine structure of this level was performed by the zero field optical double resona
