Results from the design of a high-pressure chamber and its components, recently developed at the Lund Institute of Technology, are presented. The results show that at high pressures, when the lubricants have solidified, the density varies linearly with the pressure and the shear strength also increases nearly linearly with pressure. This is also true for the investigated gasses when they are compr

A low molecular weight heparin (LMW-heparin) with a mean molecular weight of 4900 dalton was prepared by controlled enzymatic depolymerization of conventional porcine mucosal heparin. The effects of 2,500, 5,000 and 10,000 U (XaI; 29, 58 and 116 mg) on factor Xa inhibition (XaI), factor IIa inhibition (IIaI), APTT, AT III and platelet count were compared to those of 5,000 U (XaI; 26 mg) of convent

Software inspection is a method to detect faults in the early phases of the software life cycle. In order to estimate the number of faults not found, capture-recapture was introduced for software inspections in 1992 to estimate remaining faults after an inspection. Since then, several papers have been written in the area, concerning the basic theory, evaluation of models and application of the met

Large neutron excess poses new issues concerning the competition of deformation and pairing as well as changes in nuclear shell structure.

The mechanism of thermally induced oxidation of Fe2+ from natural pyrope has been studied at 1000 and 1100 degreesC using Fe-57 Mossbauer spectroscopy in conjunction with XRD, XRF, AFM, QELS, TG, DTA and electron microprobe analyses. At 1000 degreesC, the non-destructive oxidation of Fe2+ in air includes the partial stabilization of Fe3+ in the dodecahedral 24c position of the garnet structure and

Psychiatric casualties among soldiers constitute an inevitable part of modem warfare. For the past hundred years Medicine and Society have shown a growing interest in the combat reactions. The focus has shifted from an organic one towards a psychological and psychiatric perspective. Cultural, social, economical and political forces have influenced the scientific development from the Shell shock to

This article outlines laboratory and analytical studies of salt frost scaling and internal frost resistance of Self-Compacting Concrete, SCC, that contains increased amount of filler, different air content and dissimilar methods of casting. The result were compared with the corresponding properties of normal concrete, NC, with the same water-cement ratio, w/c = 0,39 and air content, 6%. Both 28 an

A novel multilayer mirror was designed and fabricated based on a recently developed three-material technology aimed both at reaching reflectivities of about 20% and at controlling dispersion over a bandwidth covering photon energies between 35 and 50 eV. The spectral phase upon reflection was retrieved by measuring interferences in a two-color ionization process using high-order harmonics produced

During biosynthesis of chlorophyll, Mg2+ is inserted into protoporphyrin IX by magnesium chelatase. This enzyme consists of three different subunits of approximate to 40, 70 and 140 kDa. Seven barley mutants deficient in the 40 kDa magnesium chelatase subunit were analysed and it was found that this subunit is essential for the maintenance of the 70 kDa subunit, but not the 140 kDa subunit. The 40

The photochemistry of low lying excited states of six different fluorinated bromobenzenes has been investigated by means of femtosecond laser spectroscopy and high level ab initio CASSCF/CASPT2 quantum chemical calculations. The objective of the work was to investigate how and to what extent light substituents, position on the benzene ring and number, would influence the dissociation mechanism of

Myometrial norepinephrine was measured consecutively with high-performance liquid chromatography in women who delivered by cesarean section. The previously recorded marked reduction in tissue norepinephrine at the end of normal pregnancy was confirmed. When cesarean section was performed because of abruptio placentae/hemorrhage, impending asphyxia, dystocia or preeclampsia, the norepinephrine conc

Electron emission, in resonance with soft X-ray absorption, appears to provide a measure of the dispersion of the highest occupied and the lowest, core-hole distorted, unoccupied pi-bands in poly(p-phenylenevinylene).

The water vapour resistance of clothing ensembles is not as commonly determined as dry thermal insulation. The measurement techniques are more complicated and the measurement values differ among laboratories. Due to complicated moisture transfer process through clothing ensemble, the moisture absorbed and evaporated varies in transient and steady state phases depending on properties, thickness of

Repeated ribs are frequently employed to promote turbulence and to enhance heat transfer in various ducts. In the present study, liquid crystal thermography was applied to the study of heat transfer from a square channel having one surface heated at uniform heat flux and roughened by repeated ribs. The continuous and truncated ribs, having square sections, with height-to-hydraulic diameter ratio o

Popular Abstract in Swedish I Sverige har andelen förtidspensionärer ökat under lång tid och uppgick år 1998 till 7.6% av befolkningen i arbetsför ålder (16-64 år). Den vanligaste orsaken till att en individ förtidspensioneras är reducerad arbetsförmåga till följd av problem i rörelseorganen. Kunskaperna om förtidspensionärers livskvalitet är bristfälliga. Syftet med denna studie var att studera lThe starting-point of this thesis was the high rate of disability pensioners in Sweden and the lack of knowledge about what a disability pension entails for quality of life (QL). The aim of the study was to gain knowledge about QL among disability retirees with musculoskeletal disorders (ERPs). A questionnaire was sent in 1992 to 450 ERPs in Kristianstad Municipality, Sweden, granted their disabil

In Sweden, traumatic brain injury (TBI) is a major cause of disability across all ages, and the need for rehabilitation and long-term follow-up is as important as in many other countries. This article presents the rehabilitation of TBI in Sweden. Strengths and weaknesses of TBI rehabilitation within the Swedish healthcare system are described, together with examples of research and development.
