Popular Abstract in Swedish Vattenkraft är Islands främsta energikälla. År 2005 svarade vattenkraft för 80,8% av all elproduktion på Island (7015 Gwh). Vattenkraft påverkas av både variationer och förändringar i vattenflöden. Denna avhandling fokuserar på studier av trender och variationer i tidsserier av vattenflöden och klimatvariabler, kombinerat med modellering av avrinningsområden och analys Hydropower is the main source of electricity production in Iceland. In 2005, 80.8% of all electricity was generated by hydropower (7015 GWh). Hydropower production is affected both by variations and changes in discharge. This thesis focuses on studies of the trends and the variability found in records of discharge and climatic variables, combined with watershed modelling and an analysis of a proje

The mixotroph Poterioochromonas malhamensis was grown in batch and semicontinuous cultures in order to examine the dependence of phagotrophy versus phototrophy at bacterial densities similar to those found in oligo- and mesotrophic lakes in combination with differing light regimes. In addition, the growth rates and biomass accumulation of the mixotroph were compared to those of the heterotroph Spu

We present new results for relative sea-level change for Southern Greenland for the interval from 9000 cal. yr BP to the present. Together with earlier work from the same region this yields a nearly complete record from the time of deglaciation to the present. Isolation and/or transgression sequences in one lake and five tidal basins have been identified using lithostratigraphic analyses, sediment

High-spin states of the neutron deficient (100)pd nucleus have been investigated via the Cr-50(Ni-58, 4p alpha) and Zn-70(S-36,6n) heavy-ion induced reactions. For the detection of evaporated particles and gamma rays the NORDBALL array equipped with ancillary detectors and the EUROGAM II detector system were utilized. By the use of in-beam spectroscopic methods 89 transitions belonging to (100)pd

The effects of intracameral injections of cholecystokinin (CCK) on the pupil size were determined in monkeys, cats, rabbits, rats and guinea-pigs. In animals under muscarinic cholinergic blockade, CCK caused miosis in monkeys but not in the other species investigated. In monkeys CCK-8 was more potent than CCK-33, which was, however, much more potent than non-sulphated CCK-8. These observations ind

Abstract in Norwegian Den kalde krigens slutt og Sovjetunionens fall har gjort det lettere for personlige kontakter på tvers av de «gamle grenser». Økt migrasjon fra det tidligere Sovjet, samt fra de nye statene i Sentral- og Øst-Europa, er et kjennetegn på den postsosialistiske perioden. Denne statistisk målbare forandringen har også fått følger på det diskursive planet. Migrasjonsproblematikken

Purpose: To investigate the effect of different levels of visual field defect in glaucoma on utilities and to test if utilities could be assessed using a general questionnaire such as the EQ-5D. Methods: A cross-sectional study in 199 patients with ocular hypertension or open-angle glaucoma grouped into 5 severity stages according to visual field defects was performed in 4 specialized ophthalmic c

While the concept of regular equivalence is equally applicable to dichotomous as well as valued networks, the identification of regular blocks in regular blockmodels is somewhat problematic when dealing with valued networks. Applying the standard procedure for identifying ties in such blockmodels, a procedure perhaps most suited for dichotomous networks, does tend to generate block images and redu

CS 22949-037 is one of the most metal-poor giants known ([Fe/H]~-4.0),and it exhibits large overabundances of carbon and nitrogen (Norris etal.). Using VLT-UVES spectra of unprecedented quality, regardingresolution and S/N ratio, covering a wide wavelength range (from lambda= 350 to 900 nm), we have determined abundances for 21 elements in thisstar over a wide range of atomic mass. The major new d

This study is about how the 'global' becomes localized and how the 'local' is articulated through the 'global'. It deals with the Van (forest) Gujjars, a people of nomadic forest pastoralists who inhabit the Central Himalayas of India. The study has two main foci: One is the everyday life-world of the Van Gujjars in the forest - a Van Gujjar ethnography - and the other is the conflict over 'conser

PURPOSE: This study used simultaneous videomanometry to measure pressure characteristics in a group of patients with evidence of laryngeal and/or tracheal barium penetration, and to compare the results to those of one group of healthy volunteers and one group of patients with dysphagia but a normal barium swallow. MATERIAL AND METHODS: Videomanometry during barium swallowing was performed in 25 pa

We wanted to test whether living environment, occupation and social position are risk factors for asthma and chronic bronchitis/emphysema (CBE). The prevalence of bronchial asthma, CBE, respiratory symptoms and smoking habits in a random sample of 12,071 adults aged 20-59 years was assessed in a postal survey with a slightly modified questionnaire previously used in central and northern Sweden (Th

BACKGROUND: Vascular rings are a classical cause of tracheal and esophagus compression. We report the case of such an abnormality in an infant with neurofibromatosis. CASE REPORT: A 1 week-old male infant with a familial neurofibromatosis presented a stridor with severe respiratory distress. A vascular ring was demonstrated and operated on. The stridor persisted after surgery. A postoperative oeso

The interaction of ink and newspaper has been investigated and the specific question of penetration of ink into the paper has been addressed with a nuclear microprobe using particle induced X-ray emission, The penetration depth of the newsprint is a critical factor in terms of increasing the quality of newsprint and minimising the amount of ink used. The objective of the experiment was to relate t

In this study a method for the analysis of simultaneous multiple measurements of kinematics and stabilizing forces related to human postural dynamics is proposed. Each subject in a group of normal subjects (n=10) was tested with eyes-open and eyes-closed with simultaneous but uncorrelated vestibular and proprioceptive stimuli in order to investigate the contributions of individual sensory feedback
