This thesis deals with the empirical testing of trade theories, traditionally used to analyze international trade, using regional data on production and trade. This thesis consists of three main essays. In the first essay, we analyze Swedish regional production. In the first part, we focus on the effects of comparative advantage in predicting regional manufacturing production. In so doing, we use
Under seeing limited conditions very high resolution spectroscopy becomes very difficult for extremely large telescopes (ELTs). Using adaptive optics (AO) the stellar image size decreases proportional with the telescope diameter. This makes the spectrograph optics and hence its resolution independent of the telescope diameter. However AO for use with ELTs at visible wavelengths require deformable
A terpyridine ligand has been covalently linked to a Ru(bpy)(3) complex via an amide bond. By using this functionalized terpyridine ligand, a series of multinuclear bimetallic complexes have been synthesized and characterized. One of these complexes has the structure of di-mu-oxobridged Mn dimer. EPR spectra of this complex showed that, depending on the procedure for the preparation, the oxidation
The role of the humoral immune response in herpes simplex encephalitis (HSE) is largely unknown. The finding that herpes simplex virus type 1 (HSV 1) induced IgG Fc receptor binds to all IgG subclasses except IgG 3 prompted an investigation of anti-HSV activity in IgG subclasses from serum and cerebrospinal fluid (CSF) in ten patients with proven or highly probable HSE by means of a monoclonal ant
We present the joint maximum likelihood (ML) symbol-time and carrier-frequency offset estimator in orthogonal frequency-division multiplexing (OFDM) systems. Redundant information contained within the cyclic prefix enables this estimation without additional pilots. Simulations show that the frequency estimator may be used in a tracking mode and the time estimator in an acquisition mode.
Various polymer electrolytes based on boronate esters and different lithium and sodium salts have been evaluated in electrochromic (EC) devices based on WO3 films. The results showed that the ionic conductivity of the electrolytes was not the most important parameter for the colouration performance of these devices. The use of solid electrolytes containing LiClO4 resulted in a higher colouration p
Chordoma is a rare, low- to intermediate-grade malignant tumor involving the axial spine. Cytogenetic data on these tumors have been limited to 25 cases. The findings of clonal chromosome aberrations in five new cases are presented. One of these and two previously reported cases have been studied with multicolor combined binary ratio labeling fluorescence in situ hybridization (COBRA-FISH). The ka
The basic helix-loop-helix (bHLH) transcription factor mammalian achaete-scute homolog-1 (MASH-1 in mouse and HASH-1 in human) is essential for proper development of olfactory and most peripheral autonomic neurons, and for the formation of distinct neuronal circuits within the central nervous system. We have previously shown that HASH-1 is expressed in neuroblastoma tumors and cell lines, and in t
Abstract in UndeterminedThis chapter will address both theoretical and methodological issues in pause analysis. First, the theoretical assumptions concerning how pause analysis can contribute towards our understanding of written language production are discussed. Subsequently, some measures, methods and tools for automatic pause analysis are presented and some empirical analyses are given. Most of
A coupled lake-catchment model was developed to examine the controls on lake-level changes in currently overflowing lakes during Holocene. The lake energy-balance is simulated as the one-dimensional vertical heat transfer by eddy diffusion and convective mixing. The accumulation and ablation of lake ice, and snow cover on the ice, is simulated thermodynamically. The lake water-balance is given by
Diabetic treatment aims at achieving a normal blood glucose concentration as reflected by the glycosylated haemoglobin concentration. Intensive treatment by insulin pump or multiple insulin injections is thought to achieve this. In an unselected group of outpatient diabetics metabolic control was the same after one, two, three, or more injections, which suggests that the mode of treatment was opti
Five patients with rheumatoid arthritis or osteoarthrosis of the wrist joint were followed up for 15 ( 14 - 17) years after wrist-joint arthroplasty with semiconstrained artificial joint mechanisms that had been anchored to bone using the osseointegration principle. They were fixed by one titanium screw introduced into the radius, and two or more titanium screws introduced distally into the metaca
Rats, mice and gerbils were continuously exposed to 150 ppm trichloroethylene (TCE) for 30 days. In all three species, there was a marked increase in liver weight. In mice the weight increased more (86%) than in rats and gerbils (20%). After exposure the activity of acid phosphatase, a lysosomal marker enzyme, was tested in different brain areas, using a system which had a limit of detection of ±
Objective: The aim of the present study was to map out what kind of psychotropic drugs are prescribed for elderly residents in assisted-living homes and how they relate to age, sex, form of living, psychiatric diagnosis, care needs and mental health status, and to identify factors of importance for their use; and to study the indication for treatment and the evaluation of the effects of treatment.
During the past century, Lake Takern and Lake Krankesjon, southern Sweden, have shifted repeatedly between a state of clear water and abundant submerged vegetation, and a state of turbid water and sparse vegetation. Long-term empirical data on such apparently alternative stable state dynamics are valuable as complements to modeling and experiments, although the causal mechanisms behind shifts are
We are investigating means of handling microparticles in microfluidic systems, in particular localized acoustic trapping of microparticles in a flow-through device. Standing ultrasonic waves were generated across a microfluidic channel by ultrasonic microtransducers integrated in one of the channel walls. Particles in a fluid passing a transducer were drawn to pressure minima in the acoustic field
