Properties of varved sediments from Lake Logurinn in eastern Iceland and their link to climate and glacial processes of Eyjabakkajokull, an outlet glacier of the Vatnajokull icecap, were examined. A varve chronology, which covers the period AD 1262-2005, was constructed from visual observations, high-resolution images, X-ray density and geochemical properties determined from X-radiography and X-ra

As a continuation of the work on the development of setting the requirements for ventilation of a bicycle helmet for commuters, 15 full scale helmet mock-ups were created by the students of the Estonian Academy of Arts. In order to encourage creativity for ventilation solutions the students were not restricted to consider the other properties except it was pointed out that the meaning of helmets u

Sulfur in coal and pulp have been characterized using pyrolysis–gas chromatography with a sulfur-selective flame photometric detector (Py–GC/FPD). The samples (50–150 µg) were pyrolyzed at temperatures between 300 and 1400°C usually followed by a combustion in oxygen at high temperature (>1000°C). The main sulfur-containing products were low-molecular compounds such as H2S, COS, SO2, CH3SH and CS2

Popular Abstract in Swedish Höftfraktur är en vanlig skada, som huvudsakligen drabbar äldre kvinnor, och oftast orsakas av ett ringa våld. Det är vanlig orsak till funktionsnedsättning, sjuklighet och dödlighet hos de äldre. Både incidensen (antal nya fall per antal innevånare och år) av höftfrakturer och det totala antalet har ökat de senaste årtiondena. Höftfrakturer medför stora kostnader för sHip fractures are a common cause of morbidity and mortality in elderly patients, with a high risk of functional impairment and institutionalization. The incidence and number of hip fractures have increased during the recent decades and hip fractures consume considerable health-care resources. The incidence of hip fractures in Malmö, Sweden, 1992–95, is described in Paper I. The annual incidence pe

Popular Abstract in Swedish I avhandlingen argumenterar författaren för att antisemitismen var självklar i Sverige årtiondena kring sekelskiftet 1900. Antisemitismen kom till uttryck bland annat i skämtpressen. Den sistnämnda utgjorde ett viktigt inslag i såväl den framväxande masskulturen som i den politiska kulturen. Det var inte minst via skämtpressen som bilden av "juden" som en "rastyp" skildIn this dissertation it is argued that anti- Semitism was self evident in Sweden at the turn of the century 1900. Through an analysis of the comic press, which was a crucial element in mass culture and political life, the author tries to demonstrate how the everyday version of a national Swedish identity was constructed in opposition to 'The Jew'.In the decades either side of 1900, anti-Semitism h

An old building belonging to the Royal Netherlands Academy of Arts and Sciences, situated on the bank of Amsterdam's Kaisergracht canal, formed the home of a small research department specializing in the study of dialects and Dutch folk culture up until 1988. Excerpts, records, photos and drawings were collected here in these run-down premises. It was a relatively closed setting, not highly ranked

Indacaterol (IND; 150 μg), glycopyrronium (GLY; 50 μg) and mometasone furoate (MF; 160 μg [high-dose ICS] and 80 μg [medium-dose ICS]) have been formulated as a once-daily (o.d.) fixed-dose combination treatment delivered via the Breezhaler® device for the treatment of patients with asthma. In this randomized (n = 116), double-blind, double-dummy, active comparator-controlled, three-period cross-o

This study explores the experiences and reflections of staff in intellectual disability (ID) services concerning ageing with ID. Qualitative interviews were conducted with 24 staff members in group homes and daily activity centres. The findings showed that the staff were uncertain about the signs of ageing in people with intellectual disabilities; they compared the life conditions of these people

A computer model of X-ray mammography has been developed, which uses quasi-realistic high-resolution voxel phantoms to simulate the breast. The phantoms have 400 μm voxels and simulate the three-dimensional distributions of adipose and fibroglandular tissues, Cooper's ligaments, ducts and skin and allow the estimation of dose to individual tissues. Calculations of the incident air kerma to mean gl

We characterized particulate emissions from vegetation fires by burning Indonesian and German peat and other biomass fuels in a controlled laboratory setting. By measuring cloud condensation nuclei (CCN) both as a function of particle diameter (dp) and supersaturation (S), we discovered particles in peat smoke that were not activated to cloud droplets at high S (1.6%). These hydrophobic particles

The Long-tailed Duck Clangula hyemalis is the main offshore wintering seaduckspecies in the Baltic region, although numbers have declined steeply since the early 1990s. The reasons for the decline are not well understood and information about habitat choice is scarce. Blue Mussels Mytilus edulis are the main food source for Longtailed Ducks in the southern Baltic Sea and here we have used both mod

Bit-error rate measurements for ON-OFF keying modulation at multigigabit per second rates over a V-band wireless link are presented. Serial data-rates from 2.5 to 20 Gb/s were studied for a 231-1 bit random sequence. Error-free data transfer over a 0.3-m link was achieved at up to 10 Gb/s. Acceptable bit-error rates, <10-5 and 10-3, were measured at up to 1.5 m for 10- and 15-Gb/s data-rate, respe

Popular Abstract in Swedish Populärvetenskaplig sammanfattning av avhandlingen "Invading Herbivory. Effects of the Golden Apple Snail (Pomacea canaliculata) in Asian wetlands". 1980 förde några affärsmän ett okänt antal individer av den sydamerikanska vattensnäckan Pomacea canaliculata till Taiwan. Snäckorna skulle odlas i dammar och säljas som människoföda på marknader i Asien och överskottet skThe South American golden apple snail (Pomacea canaliculata) was intentionally introduced to aquacultures in South East Asia to produce snails for human consumption, but the aquatic snails soon escaped and started to consume large amounts of rice seedlings. The aim of this thesis was to quantify the effects of this invasive herbivore on aquatic plants in natural wetlands since previous research h

Popular Abstract in Swedish I Big Bang, då vårt Universum skapades, bildades i princip endast de två lättaste grundämnena, väte och helium. Alla andra grundämnen har skapats, och skapas fortfarande, i olika typer av stjärnor under olika utvecklingsfaser. Detta betyder att precis alla atomer, förutom väte och helium, som bygger upp alla saker, växter, djur och människor i vår omgivning, har bildatsDisregarding the small primordial traces of the lightest elements, all metals have been formed in stellar processes, which means that the relative amount of metals in the Universe increases for every stellar generation. This build-up of elements is called chemical evolution and might be used both to constrain stellar models as well as understanding the formation and evolution of stellar population

In this paper, we propose a method for selfcalibration of a robotic manipulator force observer, which fuses information from force sensors and accelerometers in order to estimate the contact force exerted by a manipulator to its environment, by means of active motion. In robotic operation, during contact transition accelerometers and force sensors play a very important role and serve to overcome m

The sequence of the mitochondrial (mt) DNA of the horse (Equus caballus) was determined. The length of the sequence presented is 16 660 bp. This figure, however, is not absolute due to pronounced heteroplasmy caused by variable numbers of the motif GTGCACCT in the control region of different molecules. Boundaries of the 13 peptide-coding genes were determined by the presence of start and stop codo

Nocturnal animals are said to sacrifice colour vision in favour of increased absolute sensitivity. This is true for most vertebrates that possess a dual retina with a single type of rod for colour-blind night vision and multiple types of cone for diurnal colour vision. However, among the nocturnal vertebrates, geckos are unusual because they have no rods but three cone types. Here, we show that ge

The studies presented here have shown that it is fully possible to influence energy consumption through information. An increase in the knowledge among consumers will motivate them to be more energy efficient. Since several interrelated factors are involved in this knowledge level, it is difficult to establish the individual influences but such factors as the electricity bills, electricity meterin

Popular Abstract in Swedish Tillväxthormon (GH) insöndras stötvis från hypofysen. Insöndringen är som högst nattetid, och de högsta nivåerna ses under puberteten för att därefter avta succecivt med ökande ålder. En av de vanligaste orsakerna till brist på GH är godartade tumörer i hypofys och hypofysnära områden där även behandling med kirurgi och strålbehandling kan bidra till hypofysinsufficiensIn childhood onset growth hormone deficiency (GHD) a reduction in cardiac left ventricular mass (LVMi) and impairment of cardiac systolic function, as well as in glomerular filtration rate (GFR) has been shown. In study I, we showed that a low dose of GH treatment for 10 months resulted in increased LVMi and kidney size. No significant improvement in cardiac systolic function or GFR, except for a

The use of snus (also referred to as Scandinavian or Swedish moist smokeless tobacco), which is common in Sweden and increasing elsewhere, is receiving increasing attention since considered a tobacco smoke "potential reduction exposure product". Snus delivers a high dose of nicotine with possible hemodynamic effects, but its impact on cardiovascular morbidity and mortality is uncertain. The aim of
