We present first-principles density-functional calculations for the adsorption of water on the Ge(100) surface. The dissociation of water molecules into OH and H species is energetically favored over the molecular adsorption, where O forms a bond to the down atom of the Ge dimer, similar to the case of Si(100). However, on Ge(100) the energy barrier for water dissociation is calculated to be simil
Popular Abstract in Swedish Artros (ledsvikt) är en vanligt förekommande ledsjukdom, som ofta leder till nedbrytning av ledbrosk och förändring i ledstrukturen i övrigt. Sjukdomen kan medföra symptom som smärta, svullnad och stelhet, vilket leder till nedsatt ledfunktion. I Sverige utförs det per år ca 15000 protesoperationer (utbyte till konstgjord led) p.g.a. artros. Tidigare studier har visat aMeniscectomy is recognized as an important risk factor for the development of knee osteoarthritis (OA), a disease that traditionally has been considered as a simple "wear and tear" phenomenon. However, despite numerous reports, little evidence has been presented that a limited meniscal resection, compared with a more extensive resection, reduces the risk of OA by preserving meniscal function. Why?
The previous supersymmetric generalization of the unitary Harish-Chandra integral prompted the conjecture that the Harish-Chandra formula should have an extension to superspaces. We prove this conjecture for the unitary orthosymplectic supermanifold UOSp(k(1)/2k(2)). To this end, we construct and solve an eigenvalue equation.
Popular Abstract in Swedish Det finns två etablerade sätt att beskriva zigenarnas historia i Sverige. Historien talar antingen om hur illa myndigheterna burit sig åt mot zigenare, eller så berättar historien om zigenarnas självvalda isolering. Gemensamt för beskrivningarna är påståendet att zigenare alltid varit desamma och uppvisar ett likartat levnadssätt genom historien. I denna avhandling studThis thesis analyses Swedish gypsy policy between 1880 and 1970, as part of a larger sociopolitical project undertaken by the Swedish authorities to promote social order and stability. During this period, the treatment of marginalized groups was shaped by the same visions and objectives as for the population as a whole. Gypsies in Sweden have been subject to the same regulations for as other poor
Objective: To relate the pattern of neuropsychological impairments among schizophrenic patients to case history data and disease characteristics in a cross-sectional study of unselected patients, and to integrate these data with two previous longitudinal studies of neuropsychological impairments among schizophrenic patients. Method: One hundred consecutive schizophrenic patients were studied with

BACKGROUND: The role of cell adhesion molecules and transmigration of PMNs through the endothelial barrier is probably essential in intestinal ischemia and reperfusion (I/R)-induced gut barrier dysfunction. Although cytokines are released in I/R, it is unclear whether cytokines directly increase permeability or if this phenomenon requires both expression of cell adhesion molecules and PMN adhesion
Popular Abstract in Swedish Trälimfogar är en väsentlig del av modern träkonstruktionsteknik. För att höja förädlingsvärdet hos träråvaran, tillverkas idag flera olika sorters produkter vilka är beroende av limfogar. Exempel på sådana produkter är limträ och fanerträ (LVL). Ett annat exempel där limfogar används är vid inlimning av skruvar eller stänger för sammanfogning eller förstärkning av limtThis thesis, which is a compilation of seven papers, concerns the mechanical testing, numerical analysis and constitutive modelling of wood-adhesive bonds in timber engineering. Applications such as finger-joints, glued-laminated timber and glued-in rods are considered. The experimental studies include the testing of the fracture characteristics of wood-adhesive bonds, including both wood-to-wood
This paper describes the development and optimization of an amperometric biosensor for monitoring ethanol in beverages. The biosensor is constructed by cross-linking a quinoprotein alcohol dehydrogenase (QH-ADH) to an Os-complex-modified poly(vinylimidazole) redox polymer using poly(ethylene glycol) diglycidyl ether. The optimum biosensor configuration was evaluated by changing the ratio between e
A technology was developed to embed nm-sized metallic features in close vicinity to semiconductor heterostructures, which allows a direct integration of resonant tunneling diodes (RTD) inside the channel of permeable base transistor. A AlGaAs/InGaAs based RTD was grown by molecular beam epitaxy (MBE), with peak current density either 70 or 120 kA/cm2. A fundamental oscillation frequency
During the British Mandate period in Palestine, Jewish, Muslim and Christian chidren studied together at Anglican missionary schools. This educational project became part of wider efforts made by the Anglican Church to promote peace in Palestine. The article focuses on statements on 'friendship' made by the Anglican bishops in Jerusalem as well as the missionary teachers and how the concept was re
Typical bogs in the boreal forest zone can be characterised by hummock and hollow micro-topography and sparsely vegetated surfaces. Their energy balance has been studied much less than for other types of surface, i.e. fields and forests. Micrometeorological measurements were carried out in central Sweden at two bogs in different summer seasons. From the measured profiles of wind speed, air tempera
Background: Individuals belonging to the same family share a number of genetic as well as environmental circumstances that may condition a common SBP level. Among the genetic factors, the angiotensin converting enzyme (ACE) gene I/D polymorphism appears as a possible candidate as it might influence both SBP and the pharmacological effect of ACE inhibitors. We aimed to combine genetic epidemiology
Testicular germ cell tumours (TGCT) exhibit remarkable ability to differentiate into virtually all somatic tissue types. In this study, we investigated changes in mucin-type O-glycosylation, which have been associated with somatic cell differentiation and cancer. Expression profile of simple mucin-type O-glycans (Tn, sialyl-Tn, T), histo-blood group H and A variants and six polypeptide Ga1NAc-tran
Time-resolved small-angle neutron scattering (TR-SANS) was employed to observe temperature-induced phase transitions from the sponge (L-3 to the lamellar ( L (alpha) phase, and vice versa, in the water-oil (n-decane)-non-ionic surfactant (C12E5 system using both bulk and film contrast. Samples of different bilayer volume fractions phi and solvent viscosities eta were investigated applying various
