Osteoporosis is characterized by a decreased bone mass and an increased bone fragility and susceptibility to fracture. Patients with a fragility fracture at any site have an increased risk of sustaining future fractures. Orthopedic surgeons manage most of these fractures and are often the only physician seen by the patient. Mounting evidence that orthopedic surgeons are not well attuned to osteopo
Synthesis of 1-glyceryl monooleyl ether (GME) has been accomplished yielding material of high purity (99.6%). The aqueous phase behavior of synthesized lipid has been investigated by using polarized microscopy and small angle X-ray diffraction. As a result, a partial temperature-composition phase diagram has been constructed. GME forms a reversed micellar solution and reversed hexagonal liquid cry
A photoluminescence study of self-assembled InAs/GaAs quantum dots under the influence of magnetic fields perpendicular and parallel to the dot layer is presented. At low temperatures, the magnetic field perpendicular to the dot layer alters the in-plane transport properties due to localization of carriers in wetting layer (WL) potential fluctuations. Decreased transport in the WL results in a red
Identifying genes that regulate polygenic diseases influenced by the environment such as rheumatoid arthritis (RA), has so far proven to be difficult. By using an alternative approach, i.e., linkage analysis using relevant animal models we succeeded in finding the Ncf1 gene residing in the Pia4 quantitative trait locus to be responsible for the severity of pristane induced arthritis in rats. The i
The success of clinical boron neutron capture therapy (BNCT) lies in the ability to manage the radiobiological effect on the tumour and healthy tissue, and thus, accurate dosimetry measurements is pertinent for each individual patient. In the present work we investigate the possibility of performing online prompt gamma tomography (PGT) during BNCT. A prototype detector system was constructed, whic
In this paper a combustion diagnostic method is presented where measured pressure data is used to calculate the heat release, local temperatures and concentrations of NO and other species. This is done by a multizone model where the lambda value, i.e. 1/equivalence ratio, in each zone can be chosen arbitrarily. In homogenous charge engines lambda is given by the global air/fuel ratio. The local la
Popular Abstract in Swedish Utgångspunkten för denna avhandling är de många bekymmer som präglar vår tid - däribland också bekymret om frivillighetens framtid i ett postmodernt samhälle. Det är en paradox, när det å ena sidan hävdas att det moderna samhället är i kris, att den sociala gemenskaperna har brutit samman och att människor inte längre ställer upp, engagerar sig och hjälper varandra. OchThe theme of this thesis is motives for voluntarism - with particular focus on volunteering in social work compared to voluntary work in sports clubs and patient associations. It is based on a combination of different data sources and methodological approaches: surveys, analyses of letters from volunteers and literature studies. Theoretically the thesis is based on two sets of sociological theorie
The influence of pH and surfactants during treatment of E-stage effluent was studied. Three tubular ultrafiltration membranes were used in the experiment. The flux of the three membranes was at its highest level at the normal, high pH, of the effluent. In this experiment the densest membrane showed the greatest flux decrease, while the most ouen membrane was either unaffected bv variations in ph o
Popular Abstract in Swedish Del 1. Introduktion I kapitel 1 presenteras arbetets problem, syfte och metod. Det arbete som olika frivilligorganisationer och deras medlemmar utför har de senaste åren uppmärksammats alltmer. Detta ökade intresse finner man såväl i Sverige som internationellt. Fokus i detta arbete riktas mot drivkrafterna bakom frivilligt engagemang. Det övergripande problemet är varfThis thesis focuses on the incitement to commitment and voluntary work. The overall problem is the question why you get involved in voluntary work for an organisation like Lutherhjälpen, the organisation for international development co-operation of the Church of Sweden, one of the largest NGOs of the country. The theoretical perspectives are seen from the position of the increasing pace of change
Signals of QCD instanton-induced processes are searched for in deep-inelastic scattering (DIS) at the electron-proton collider HERA in a kinematic region defined by the Bjorken-scaling variables x > 10(-3), 0.1 < y < 0.6 and photon virtualities 10 less than or similar to Q(2) < 100 GeV2. Several observables characterising hadronic final state properties of QCD instanton-induced events are exploite
The electrochemical and the electrocatalytic behavior for NADH oxidation of a newly synthesized phenothiazine derivative, 16H,18H-dibenzo[c,1]-7,9-dithia-16,18-diazapentacene (DDDP), adsorbed on solid spectrographic graphite and on graphite powder or on zirconium phosphate (ZP), both entrapped in carbon paste, were compared. Experiments using cyclic voltammetry and a rotating disk electrode, perfo
Whey protein adsorption on stainless steel surfaces was investigated by in situ ellipsometry under well-defined flow conditions and protein solution residence times. The size distribution in solution of the protein aggregates formed under the same conditions was determined by dynamic light scattering. The adsorption was performed at 72 degrees C and 85 degrees C which is below and above the unfold
