Faxeholm i maktens landskap : en historisk arkeologi

Popular Abstract in Swedish Hur gick det till när det svenska riket expanderade norrut och införlivade Hälsingland? Denna bok är uppställd som en generalhypotes över denna långt utdragna process, som tar sin utgångspunkt i den samhälleliga kollaps som är skönjbar under 500-talet. De inhemska maktstrukturer som gradvis byggdes upp efteråt kom under medeltidens inledande århundraden att få känna på In which way did the power structures of central Sweden expand into the territories north of the forest Ödmården during the Middle Ages? This text reads like a general hypothesis for this process, which attempts to incorporate all relevant elements in the Medieval landscape of power. The study area chosen is the province of Hälsingland. The chronological take-off is the 6th century AD, when settle

Laser Sensing for Quality Control and Classification – Applications for the Food Industry, Ecology and Medicine

Monitoring constitutes a cornerstone, both for efficient control of optimized industrial processes and for obtaining knowledge about non-controlled, natural phenomena. This thesis is all about monitoring, or measurements. In this case the primary information is gathered with light, and in a non-intrusive, and usually a stand-off or remote way. The applications of optical monitoring in this work

Inadequate opening capacity of the eustachian tube in Meniere's disease.

Abstract Conclusion: In this physiological study subjects with Meniere's disease (MD) had high resistance to opening of the eustachian tube (ET) in three of four provocation tests. These subjects can be exposed to pressure deviations in the middle ear (ME) above their equalizing capacity. Transmission of the pressure deviations to the inner ear fluids and influence of the symptoms of MD are feasib

Generation of X-rays For Medical Imaging By High-power Lasers - Preliminary-results

PURPOSE: To evaluate the use of x-ray imaging performed with a high-power laser system in biologic and medical studies. MATERIALS AND METHODS: A compact terawatt laser system based on chirped pulse amplification in titanium-doped sapphire was used. X rays were generated by irradiating a high-atomic-number target (tantalum). RESULTS: When photons with an energy below 10 keV were removed with use of

An Experimental and numerical study of heat transfer and pressure drop on the bend surface of a U-duct

This work concerns experimental and numerical studies of pressure drop and heat transfer for turbulent flow inside a U-duct and in particular the bend part. Such duct geometries can be found in many engineering applications where cooling air extracts heat from hot internal walls of the duct, e.g., passage cooling inside gas turbine blades. The details of the duct geometry were as follows: the cros

The Tupian Expansion

This chapter explores the expansion of the Tupian peoples across greater Amazonia to better understand the mechanisms and processes of cultural and linguistic contact and change. Tupian languages are or were spoken among indigenous groups distributed from the Brazilian Atlantic coast through Paraguay to the eastern Andean slopes of Peru. The investigation uses GIS (Geographical Information Systems

New Isomers in the Neutron-Rich Region Beyond 208Pb

The region of neutron-rich nuclei beyond 208Pb has been very difficult to explore due to its high mass and exoticity. However, recent experimental improvements allowed one to perform a quite extended isomer decay spectroscopy of these nuclei.

A Current Swedish Survey on Attitudes to Science-and-Religion

Artikeln presenterar resultat från en enkätundersökning bland 2000 personer bosatta i Sverige. I enkäten ställdes bland annat frågor om synen på förhållandet mellan naturvetenskap och religion. Resultaten ger vid handen att man uppfattar naturvetenskap och religion som kompletterande varandra, och att denna uppfattning är vanligare med högre utbildning. Uttalade ateister uppfattar i hög utsträckni

Histopathology indicates lymphatic spread of a pelvic retroperitoneal ectopic pregnancy removed by robot-assisted laparoscopy with temporary occlusion of the blood supply.

Abstract Retroperitoneal ectopic pregnancies are extremely rare and a diagnostic and therapeutic challenge as an early diagnosis is difficult and all treatments entail a risk for severe bleeding. We present a case of a live completely retroperitoneal ectopic pregnancy in the right obturator fossa. Following 3D color Doppler vaginal ultrasonography to evaluate the relation to larger blood vessels t

Differential effects of three echovirus strains on cell lysis and insulin secretion in beta cell derived lines.

In an earlier study, infection of human pancreatic islets with epidemic strains of echovirus (E4, E16, E30), with proven but differently ability to induce islet autoimmunity, resulted either in a severe damage (i.e. E16 and E30) or proceeded without visible changes in infected islets (i.e. E4). In this study, the ability of these strains to replicate in beta cells and the consequence of such an in
