Popular Abstract in Swedish Dieselmotorn, uppkallad efter sin uppfinnare Rudolf Diesel, patenterades 1892 och har sedan dess bidragit väsentligt till utvecklingen av samhället. Den viktigaste användningen är som kraftkälla i fordon och detta användningsområde ökar fortfarande. Andelen dieselmotorer i nyregistrerade personbilar i Västeuropa har nyligen passerat 50 %. För kommersiella fordon som lasThis project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. The results can be divided into two main categories: one about evaluations of optically accessible engines and one about studies of e

Micromotion of the tibial component in 40 knee arthroplasties for gonarthrosis was studied rising Roentgen stereophotogrammetric analysis. The stability of this component was assessed for 2 years' postoperatively. in all arthroplasties, an attempt was made to reconstruct the preoperative posterior slope. Posterior cruciate-retaining (CR) and posterior-stabilized (PS) components showed at 2 years a

In the context of an European collaborative research project (EURELD), a study on attitudes towards medical end-of-life decisions was conducted among physicians in Belgium, Denmark, Italy, the Netherlands, Sweden and Switzerland. Australia also joined the consortium. A written questionnaire with structured questions was sent to practising physicians from specialties frequently involved in the care

An integrated IT technology, characterized by a change in information support from a strong specialization towards greater integration has been introduced within the surveying company in Sweden. The aim of this study is to compare and describe effects of the transition to this new information technology in relation to job and organizational characteristics and effectiveness and well-being measures

Factor VIII (FVIII)-bypassing agents have complex modes of action but all control bleeding in inhibitor patients by triggering the generation of thrombin. No routine test is available for monitoring this therapy in patients with inhibitors against FVIII. We present an assay that records FEIBA- or FVIIa- mediated changes in thrombin generation (TG) in FVIII inhibitor plasma samples. In plasma sampl

This work describes the use of focused, high-intensity light from a Ti: sapphire laser that generates femtosecond pulses to irradiate mixture of CeO2 and Tb4O7 under ambient conditions. The prepared samples were investigated by means of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM). XRD and XPS measurement results demonstrated that solid sol

The influence of different pressures of CO2 and the addition of caprylic acid methyl ester as an entrainer was studied for the extraction process of borage seed. The increase of CO2 pressure from 100 to 350 bar resulted in the increase in extract yield from 0.14 to 24.29% (w/w) while the changes in the extract composition were not so considerable. The highest solubility of pure caprylic acid methy

Caregiving relatives continue to feel primarily responsible for the care and well-being of elderly persons, when they are admitted to hospital. Although involvement of relatives in decision-making is rare, and the hospitalisation therefore may be a frustrating experience, little is known of relatives, experience of the hospitalisation of elderly persons from a life-world perspective. In this pheno

ZnWO4, ZnWO4 : Fe and ZnWO4 : Mo crystals were investigated by the methods of time-resolved spectroscopy in the temperature range of 4.2-300 K. It is shown that the Mo and Fe impurities significantly reduce the light yield of ZnWO4. The main 2.5 eV emission of ZnWO4 and the 1.77 eV emission band of ZnWO4 : Mo are shown to originate from the triplet excited state of the WO6 and MoO6 complex, respec

We report on the shear induced transition from the L-3- to the L-alpha-phase studied by means of flow birefringence using the system pentaethyleneglycol monododecylether (C12E5), decane, water. The dependence of the critical shear rate, at which the transition from the isotropic state to the anisotropic takes place, on membrane volume fraction was studied in temperature ramp experiments at differe

The stress field in a finite, edge cracked specimen under load is computed using algorithms based on two slightly different integral equations of the second kind. These integral equations are obtained through left regularizations of a first kind integral equation. In numerical experiments it is demonstrated that the stress field can be accurately computed. Highly accurate stress intensity factors

A thermostable, alkaline active xylanase was purified to homogeneity from the culture supernatant of an alkaliphilic Bacillus halodurans S7, which was isolated from a soda lake in the Ethiopian Rift Valley. The molecular weight and the pI of this enzyme were estimated to be around 43 kDa and 4.5, respectively. When assayed at 70 degrees C, it was optimally active at pH 9.0-9.5. The optimum tempera

Flat premixed burner-stabilized H-2 + O-2 + N-2 flames, neat or doped with 300-1000 ppm of NO or NH3, were studied experimentally using molecular-beam mass-spectrometry and simulated numerically. Spatial profiles of temperature and concentrations of stable species, H-2, O-2, H2O, NO, NH3, and of H and OH radicals obtained at atmospheric pressure in lean (phi = 0.47), near-stoichiometric (phi = 1.1

The objective of the present investigation was to develop a technique to synthesize submicronic particles of Nb-doped strontium titanate with a homogeneous composition. This was achieved by a modified glycine-nitrate process, using Ti-lactate, Nb-oxalate, and Sr(NO3)(2) as starting materials. A combination of both citric acid and glycine was needed in order to integrate the useful features of both

We assessed all patients who underwent tissue expansion, excluding breast reconstructions, between 1984 and 1999. A total of 237 patients had 257 expansions, normally for distorted scars, 202 of 257 cases (79%). Their mean age was 27 (range 7- 67) years, most being women, 149 of 237 (63%). The mean duration of expansion was 16 weeks (range 0.4-118). The most common site was the skull (61/257). Pro

Two complexes were isolated from aqueous Pd(NO3)(2)-Na(2)H(2)EDTA solutions and studied by single crystal X-ray diffraction, IR/Raman spectroscopy, and photoelectron spectroscopy. The first complex, Pd(Hkpda)(2) (kpda = ketopiperazinediacetate dianion, C8H10N2O5). forms yellow parallelepipeds during slow evaporation of Pd(NO3)(2)-Na(2)HEDTA solution at 25degreesC, and is a result of EDTA oxidation
