Most of the Swedish subfossil finds of terrestrial mammals have been recovered from Scania. The contributing factors may be that the locally more abundant Late Weichselian sediment basins have been exposed through the extensive practice of peat cutting during the 19th century, and that the public awareness of the significance of the bones and antlers found, prior to the birth of the modern archaeo

Efforts are currently directed towards improving the quality of sensitive tissues of fruits and vegetables after freezing and thawing. One of the methods under investigation is the combination of vacuum impregnation (VI) with cryoprotectants and pulsed electric field (PEF), applied to the plant tissue prior exposure to freezing. The influence of these processes on the freezing temperature and ice

Background. NT-proBNP may be useful for ruling out heart failure in primary health care. In this study we examined the analytical quality of NT-proBNP in primary health care on the Cobas h 232 point-of-care instrument compared with measurements performed in a hospital laboratory. Materials and methods. Blood samples requested for NT-proBNP were collected in primary health care (n = 95) and in a ho

We performed implantation experiments; applying both the chemically active oxygen ions and inactive ions of neon noble gas, to thin epitaxial films of (Ga,Mn)As ferromagnetic semiconductor. Inspection of their magnetic properties by means of a superconducting quantum interference device magnetometer revealed that the implantation with a low dose of either O or Ne ions completely suppressed ferroma

The most expensive component in a conventional solar photovoltaic (PV) system is the solar module cell. The module cost could be reduced if low-cost reflector materials are used to concentrate solar energy flux across a small module area. Three reflector materials were studied for fill-factor improvements in low concentrating system. These were anodized aluminium, rolled aluminium foil and miro re

The goal of this paper is to determine whether the photoplethysmography (PPG) can replace the ECG-based detection of heart rate turbulence. Using the PPG, classification of ventricular premature beats (VPBs) is accomplished with a linear classifier. The two conventional parameters turbulence onset and slope are studied together with a recently introduced parameter characterizing turbulence shape.

Background: Studies on leisure time physical activity as risk factor or protective factor for knee or hip osteoarthritis (OA) show divergent results. Longitudinal prospective studies are needed to clarify the association of physical activity with future OA. The aim was to explore in a prospective population-based cohort study the influence of leisure time physical activity on severe knee or hip OA

Internationally there is an on-going political struggle regarding whether to define prostitution as violence, sex or work. In Sweden, however, the national law that bans purchase of sexual services, by defining prostitution as violence against women, has strong support. The aim of this article is to identify and describe claims-making and mobilisation on the Internet against Swedish prostitution p

Popular Abstract in Swedish Bakterier är små encelliga organismer som lever i nästan varje tänkbar miljö på jorden, inklusive i och på människor. Vi är kontinuerligt koloniserade av bakterier i bland annat våra luftvägar, munhålor och mag-tarmkanaler. Denna samexistens är oftast ömsesidigt fördelaktig, eller åtminstone ofarlig för oss människor, och det är känt att bakterier hjälper oss bryta ner Nontypeable Haemophilus influenzae (NTHi) is a remarkably proficient colonizer of the human respiratory tract. The aim of this thesis has been to characterize currently known, and identify novel, bacterial factors involved in the key processes of colonization and pathogenesis, namely adherence to host tissue and evasion of the host innate immunity. We have shown that the NTHi virulence factor Pr

Measurement of cortisol concentration can contribute important information about an individual's ability to adjust to various environmental demands of both physical and psychosocial origin. However, one uncertainty that affects the possibilities of correctly interpreting and designing field studies is the lack of observations of the impact of seasonal changes on cortisol excretion. For this reason

I denna studie visar vi olika fördelar med vår e-learning-modell, som har „räddat” småspråket rumänska. Vi konstaterar dessutom att denna utbildningsmodell kan tillämpas på vilket annat språk som helst, för att uppnå ett flexibelt, rationellt, kostnadseffektivt och modernt lärande.

Multi-storey wood buildings have been increasing in popularity since a century-old ban on the construction of such buildings was lifted in 1994. Compared to conventional concrete structures, it is more difficult to build lightweight structures in such a way that noise and disturbing vibrations is avoided. To design buildings of high performance regarding sound and vibrations, it is desirable to ha

In this very short paper, I argue that it is possible to harmonize the doctrine of original sin, as western Christendom has traditionally understood it, with a polygenist account of human ancestry. To this end, particular attention is paid to the encyclical Humani Generis (1950), in which Pope Pius XII strongly cautions against polygenist ideas.

A candidate for chiral bands was found in Tl-198 for the first time in a mass region of oblate (or nonaxial with gamma >= 30 degrees) deformed nuclei. Two bands show very similar quasiparticle alignments, moments of inertia, and B(M1)/B(E2) ratios. They have a relative excitation energy of about 500 keV and different patterns of energy staggering. Calculations using the two-quasiparticle-plus-tria

This paper is the follow up of a previous work and its target is to demonstrate that the best fuel for a Compression Ignition engine has to be with high Octane Number. An advanced injection strategy was designed in order to run Gasoline in a CI engine. At high load it consisted in injecting 54 % of the fuel very early in the pilot and the remaining around TDC; the second injection is used as ignit

Laminar burning velocities for methanol, ethanol, and binary and quaternary mixtures of these with isooctane and n-heptane, have been determined using the heat flux method on a flat flame adiabatic burner. Measurements were done for an equivalence ratio range between 0.7 and 1.5 and for a range of temperatures between 298 K and 358 K at atmospheric pressure. The present study expands the available

Background and purpose With an aging population expecting an active life after retirement, patients' expectations of improvement after surgery are also increasing. We analyzed the relationship between preoperative expectations and postoperative satisfaction and self-reported outcomes with regard to pain and physical function after knee arthroplasty. Patients and methods 102 patients (39 men) with
