Age and waiting time as predictors of outcome after total hip replacement for osteoarthritis

Objective. To investigate in a prospective study the relationship between age, pre-operative status, waiting time and post-operative outcome in patients assigned for unilateral total hip replacement (THR) due to osteoarthritis (OA). Method. One hundred and forty-eight patients (mean age 71 yr) with primary OA of the hip were investigated pre-operatively and 3, 6 and 12 months post-operatively with

The surface exposed amino acid residues of monomeric proteins determine the partitioning in aqueous two-phase systems

It is of great interest and importance how different amino acid residues contribute to and affect the properties of a protein surface, Partitioning in aqueous two-phase systems has the potential to be used as a rapid and simple method for studying the surface properties of proteins. The influence on partitioning of the surface exposed amino acid residues of eight structurally determined monomeric

Ja visst gör det ont när kommunala mål brister

Ja visst gör det ont när kommunala mål brister, …åtminstone om vi får tro andemeningen i de nya texterna avseende god ekonomisk hushållning som återfinns i kommunallagen och lagen om kommunal redovisning. Som bekant skall budgetens planer för verksamhet och ekonomi numera innehålla mål och riktlinjer och utvärdering av målen skall ske i årsredovisningens förvaltningsberättelse, allt i syfte att st

Vacancy-oxygen complex in Ge crystals

Vacancy-oxygen (VO) complexes in Ge crystals have been studied by means of high-resolution infrared absorption and deep-level transient spectroscopy (Laplace DLTS) measurements. It is argued that the VO center in Ge has three charge states: double negative (VO--), single negative (VO-) and neutral (VO0) with the corresponding energy levels at E(- -/-) = E-c-0.21 eV and E(-/0) = E-v + 0.27 eV. Abso

Characterization of MIMO antennas using spherical vector waves

Spherical vector waves are used to analyze multiple-input multiple-output (MIMO) antennas. An expansion of the far-field pattern in spherical vector waves gives the correlation matrix and correlation loss of the MIMO antenna in uniform multipath channels. Numerical examples of a MIMO tetrahedron and a MIMO cube are presented.

Observation and rovibrational analysis of the v(2) band of HCN-(HCl)-Cl-35

The high-resolution infrared absorption spectrum of an equilibrium mixture of HCN and HCl in a static gas long-path absorption cell is recorded in the 2500 2900 cm(-1) spectral region at 205 K. The spectrum shows rovibrational structure which has the typical appearance of a parallel band of a linear molecule and is assigned to the intramolecular H-Cl stretching vibration band upsilon(2) of the lin

An improved stereoselective reduction of a bicyclic diketone by Saccharomyces cerevisiae combining process optimization and strain engineering

The stereoselective reduction of the bicyclic diketone bicyclo[2.2.2]octane-2,6-dione, to the ketoalcohol (1R,4S,6S)-6-hydroxybicyclo[2.2.2]octane-2-one, was used as a model reduction to optimize parameters involved in NADPH-dependent reductions in Saccharomyces cerevisiae with glucose as co-substrate. The co-substrate yield (ketoalcohol formed/glucose consumed) was affected by the initial concent

Conserving approximations in time-dependent density functional theory

In the present work, we propose a theory for obtaining successively better approximations to the linear response functions of time-dependent density or current-density functional theory. The new technique is based on the variational approach to many-body perturbation theory (MBPT) as developed during the sixties and later expanded by us in the mid-nineties. Due to this feature, the resulting respo

Direct electron transfer between graphite electrodes and ligninolytic peroxidases from Phanerochaete chrysosporium

Electron transfer (ET) of ligninolytic peroxidases was studied in the bioelectrocatalytic reduction reaction of H2O2 at peroxidase-modified graphite electrodes. Specifically, native lignin (LiP) and manganese (MnP) peroxidases secreted by Phanerochaete chrysosporium, as well as a few different recombinant MnP forms were used in the electrochemical studies. The recombinant enzymes included wild-typ

Rotational capacity of reinforced concrete beams

The rotational capacity of a plastic hinge is analysed by means of a new approach, where the strain localization in the compression zone is taken into account. This leads to a strong size dependency of the rotational capacity. Comparisons with test results confirm this conclusion.

Numerical simulation of two-phase flow and heat transfer in a composite duct

In this work, a three-dimensional computational method has been further developed for a composite duct, to analyze water phase change and liquid water saturation level, two-phase flow and heat transfer in a multi-component mixture. The duct under consideration consists of a flow duct, porous layer and solid structure. Advanced boundary conditions are applied in the analysis, concerning the thermal

Quality of life and ethics-patients with ischemic heart disease

Popular Abstract in Swedish Sjukdomar som drabbar hjärtats kranskärl och ger upphov till bland annat hjärtinfarkt är den vanligaste dödsorsaken både i Sverige och i resten av världen. Avsikten med denna avhandling är att ge en bild av livskvaliteten hos hjärtpatienter samt att ta upp problem inom medicinsk etik, som berör dessa patienter. Män och kvinnor som vårdats för hjärtinfarkt vid UniversiteOne month and one year after acute myocardial infarction (AMI) (n=296), coronary artery bypass grafting (CABG) (n=99) and percutaneous coronary intervention (PCI) (n=18) patients completed a questionnaire for self-assessment of quality of life (QoL) during the period 1989?1991. Patients differed from age- and sex-matched controls (n=88) in both somatic and emotional dimensions, but less after one

A Predictive PI Controller for Processes with Long Dead Time

This paper describes a predictive PI controller with dead-time compensation. The advantage of the new controller compared with other dead time compensating controllers is that it contains only three adjustable parameters; the gain, the integral time and the dead time. The controller is also suited for processes with varying dead times.

Studiemiljöer vid Lunds universitet - en undersökning ur ett psykosocialt perspektiv

De högsta studiekraven kommer från studenterna själva. Så beskriver majoriteten av studenterna i denna studiemiljöundersökning studierna vid Lunds universitet. I andra hand betonas kraven från arbetsmarknaden och först i tredje hand utbildningens krav sådana de förmedlas i undervisningen av lärare och handledare. Undersökningen ger bilden av den existentiellt sett ensamma studenten med höga krav p
