Popular Abstract in Swedish Avhandlingen behandlar olika aspekter av produktivitet och ekonomisk tillväxt i Afrika och består av fyra kapitel. I det första kapitlet utförs en analys av de faktorer som påverkar Afrikas tillväxt på lång sikt. Analysen är baserad på en studie av ett antal Afrikanska länder som genomgått stark ekonomisk tillväxt under längre perioder. Studiens främsta slutsatser är atThe thesis comprises an introductory chapter and four research papers. The introductory chapter provides a brief overview of recent economic growth performance in Africa, places the individual papers into a coherent context, summarizes the main findings, and discusses their relevance for economic policy. The first paper, The Role of Capital Accumulation, Adjustment and Structural Change for Take-

An association between the intake of heterocyclic amines (HAs) and the development of cancer has been observed in some epidemiological studies, while in other studies no such correlation has been found. HAs are mutagenic/carcinogenic compounds formed at low levels via the Maillard reaction and a free radical mechanism during cooking of animal tissue. The addition of pure antioxidants or foods cont

On the basis of his daily life experiences of water waves the Swedish natural philosopher Emanuel Swedenborg (1688-1772) could use the wave metaphor to transfer the qualities of these waves to other physical phenomena such as sound waves and light waves. In the last issue of his scientific journal Dædalus Hyperboreus (1718), he published an overview of a new theory of tremulations. Swedenborg's mo

We present a quenching result for semilinear parabolic equations with dynamic boundary conditions in bounded domains with a smooth boundary.

Wood is a hygroscopic material; always striving to reach equilibrium with the surrounding air, and consequently the moisture content is different in different climate conditions. The strength of wood is directly dependent on the moisture content, lower moisture content leads to increasing strength. Generally, state moisture equilibrium is seldom obtained because the moisture transport in wood is v

Background and aims: A large, national, long-term, longitudinal, multi-purpose study has been launched in Sweden - the Swedish National study on Aging and Care (SNAC). The study involves four research centers collecting data in four different areas of Sweden. Methods: The study consists of two parts: the population part and the care and services part. In the population part, a large, representativ

Popular Abstract in Swedish Gummi är inte enbart olinjärt elastiskt, det är också beroende av töjningshastighet och töjningsamplitud. Kombinationen av de olinjära elastiska egenskaperna och amplitudberoendet behandlas av de modeller som föreslås i avhandlingen. Modellerna är utformade så att de snabbt ska kunna implementeras i industrin.Rubber is not only a non-linear elastic material, it is also dependent on strain rate, temperature and strain amplitude. The non-linear elastic property and the strain amplitude dependence give a non-linear dynamic behavior that is covered by the models suggested in this thesis. The focus is on a finite element procedure for modelling these dynamic properties of rubber in a way that is easy to ado

Background Epidemiological studies have, so far, identified factors associated with increased risk for incident or progressive OA, such as age, sex, heredity, obesity, and joint injury. There is, however, a paucity of long-term data that provide information on the nature of disease progression on either group or individual levels. Such information is needed for identification of study cohorts and

A low intake of calcium is widely considered to be a risk factor for future fracture. The aim of this study was to quantify this risk on an international basis and to explore the effect of age, gender and bone mineral density (BMD) on this risk. We studied 39,563 men and women (69% female) from six prospectively studied cohorts comprising EVOS/EPOS, CaMos, DOES, the Rotterdam study, the Sheffield

Background Impaired muscarinic receptor-mediated vasodilation is an important feature of early atherosclerosis. Earlier studies on apolipoprotein E-knockout mice (apoE-KO) mice suggested adverse effects of Chlamydia pneumoniae infection on the endothelial vasomotor responses of aortas to the muscarinic agonist methacholine. Using additional aorta samples the present study investigated the response

Popular AbstractSyftet med avhandlingen är att bidra med ny kunskap till det forskningsområde inom ekonomisk geografi som behandlar problem kopplade till industriell dynamik, rumslig organisering av industriell verksamhet och regional näringspolitik. Genom att studera företags strategier och relationer till andra aktörer i och utanför hemmaregionen bidrar avhandlingen till en ökad förståelse för dThe dissertation aims at making a contribution to the field of industrial organization/dynamics, spatial organization of industries and regional policy. This has been done by paying more attention to the strategies of the firm and to the link between the firms, the industry as well as the region and the implications for regional policy. More specifically, the dissertation makes a contribution to e

Background. Shipment of pancreata between distant centers is frequently associated with prolonged cold ischemia time (CIT) that leads to poorer outcomes for islet transplantation. Clinical pilot trials have indicated that oxygenation of explanted human pancreata utilizing the two-layer method (TLM) allows the use of marginal donor pancreata for islet transplantation. The present study aimed to cla

The objective was to investigate the adaptation ofthe multi-segmented body movements induced over time byvibratory proprioceptive stimulation of the calf muscles and by galvanic vestibular stimulation. Twelve normal subjects were with eyes open or eyes closed exposed to vibratory stimulation of two different amplitudes and frequencies, or to simultaneously applied galvanic and vibratory stimulatio

The present study deals with detection of intra-atrial wavefronts from atrial activation times in adjacent bipolar electrograms. A statistic of the delays within each wave-front was calculated and served as a basis for quantifying the wavefront consistency as well as the propagation of the electrical activity along the catheter. The database consisted of 19 patients for which five electrograms wer

Excited states in the N=47 nucleus Rh-92 were populated via the fusion evaporation reaction Ni-58(Ca-40,alpha pn)Rh-92 at 180 MeV beam energy. A level scheme reaching up to about 7 MeV and probable spins of (19(+)) and (21(-)) was established and interpreted with the shell model in the (p(1/2), g(9/2)) model space.

Amyloid-beta peptide (A) and the serpin proteinase inhibitor 1-antichymotrypsin (ACT) are components of the amyloid plaques associated with Alzheimer's disease (AD). A exists in soluble monomeric and oligomeric forms and in an insoluble polymerised fibrillar form, but it is not clear which of these plays the most important role in the etiology of AD. In vitro, A1-42 interacts with ACT, and as a re
