Popular Abstract in Swedish Med stigande ålder försvagas våra vävnader. Om bukväggen i ljumsken blir för svag, så kan bukinnehållet pressas ut genom svagheten. Detta kallas för ljumskbråck. Sjukdomen är mycket vanligare hos män och drabbar alla åldrar. Ju äldre man är, desto vanligare att man drabbas av ett ljumskbråck. Man upplever då, framför allt vid ansträngning, en oftast rörlig och ibland smBackground: In the nineties, the patients with inguinal hernias were exposed to several newly developed repair techniques using alloplastic mesh prosthesis. Although the scientific knowledge was limited, the new techniques were rapidly introduced due to surgical enthusiasm, but also by an eagerness to reduce the recurrence rate and to shorten the time to recovery. When the first study of this thes

The relation between information science and library science has been debated for decades, and even attempts at utilizing methods generally acknowledged as robust for the purpose of mapping research fields have yielded results with large variations. Therefore, a set of citation analyses was performed, comparing the results of analyses on information science and library science separately but also

Embryonic stem cells (ESCs) are derived from the inner cell mass (ICM) of blastocyst stage embryos, and upon differentiation into embryoid bodies (EBs) they recapitulate the genetic, cellular and morphological events occurring in early embryogenesis. Among several signalling pathways and inductive factors, the fibroblast growth factors (FGFs) and their receptors (FGFRs) have been shown to be impor

Solid tumors are composed of cancer cells, as well as resident or infiltrating non-malignant cells that contribute to the malignant state in an ecosystem generally accepted as the tumor microenvironment. Microenvironmental tumor hypoxia is the foremost leading cause of angiogenesis, i.e. the formation of new blood vessels from pre-existing vasculature, and its correlation to tumor growth and aggre

This article explains how infrastructures with a sustainability record may evolve over time into a lock-in that slows the emergence of more sustainable urban infrastructures. A study of waste incineration in the Goteborg Metropolitan Area, Sweden, serves as an illustrative case. Taking leads from Unruh (2000, 2002), four rationales of lock-in are identified in the case: institutional, technical, c

Background: Epidemiologic studies have produced conflicting results with respect to an association of dietary fat with breast cancer. Objective: We aimed to investigate the association between fat consumption and breast cancer. Design: We prospectively investigated fat consumption in a large (n = 319 826), geographically and culturally heterogeneous cohort of European women enrolled in the Europea

Several scenarios for ethanol production, methane production (by anaerobic digestion) and co-production of these, using autumn harvested hemp as substrate, were investigated and compared in terms of gross energy output. Steam pretreatment improved the methane production rate compared with mechanical grinding. The methane yield of steam pretreated stems was similar both with and without pre-hydroly

Background NKX2-1 encodes a transcription factor with large impact on the development of brain, lung and thyroid. Germline mutations of NKX2-1 can lead to dysfunction and malformations of these organs. Starting from the largest coherent collection of patients with a suspected phenotype to date, we systematically evaluated frequency, quality and spectrum of phenotypic consequences of NKX2-1 mutatio

We explore how two community-based reform models align with the World Bank's World Development Report 2004 accountability framework. Using a qualitative case study of rural Guatemalan primary schools, we examine local governance through interviews with a range of stakeholders. While both reforms appear appropriate according to the World Bank's accountability framework, especially the model giving

At the end of the eighteenth century, Edward Gibbon described the antiquarian scholars of previous generations as men of “profound learning and easy faith.” His exemplar was the Swedish polymath Olof Rudbeck, who in a series of frantic and combative tomes sought to portray Sweden as the model for Plato’s Atlantis and the seething cultural cauldron from which Western civilization had emerged. A Pil

The average charge states of Pb-188 and No-252,No-254 ions in dilute helium gas were measured at the gas-filled recoil separator TASCA. Hydrogen gas was also used as a filling gas for measurements of the average charge state of No-254. Helium and hydrogen gases at pressures from 0.2 mbar to 2.0 mbar were used. A strong dependence of the average charge state on the pressure of the filling gases was

To investigate the role of factors that modulate the association between alcohol and mortality, and to provide estimates of absolute risk of death.

Digital gameplay is now firmly embedded in everyday practices in many Scandinavian homes. This paper deals with the constitution of such practices in families by taking a closer look at the material objects essential to play and their role in the “design of everyday life” (Shove et al 2007). It uses ethnographic method and anthropological practice theory to attend to the domestic spaces of leisure

Muscle contraction studies often focus solely on myofibres and the proteins known to be involved in the processes of sarcomere shortening and cross-bridge cycling, but skeletal muscle also comprises a very elaborate ancillary network of capillaries, which not only play a vital role in terms of nutrient delivery and waste product removal, but are also tethered to surrounding fibres by collagen "wir

The validity of a Swedish translation of the Measures of Criminal Attitudes and Associates (MCAA) was evaluated. All four subscales showed acceptable reliability, but the Entitlement scale can be improved by replacing items with low loadings. Confirmatory factor analysis supported a model with one common criminal attitude factor and three subfactors (corresponding to subscales of the test). The An

We report on dissipative exciton dynamics calculations performed with the hierarchy equations of motion method for a molecular heterodimer coupled to a multi-mode Brownian oscillator bath. Coherent oscillations in the population dynamics after initial excitation of the highest exciton state are analysed in terms of a Fourier spectrum and compared to the exciton-vibronic structure of the dimer eige

Since the financial crisis of 2008 many European countries have been plagued by growing fiscal deficits and public debts. The country found by many to be the worst off is Greece and in this study we use the Solow model of economic growth to attempt to find a savings level for Greece which provides enough capital for both investment and debt service. We use two different scenarios where one is base

Populärvetenskaplig sammanfattning: Skåne är till stor del täckt av sedimentära, avlagrade bergarter t.ex. sandsten och kalksten, samt mycket yngre istidsavlagringar. Den kristallina berggrunden i Skåne utgör grunden för sedimenten och bildades huvudsakligen för mer än 1200 miljoner år sedan. Denna berggrund är bara synlig i de stora nordvästriktade horstar (åsar), som utgör ett markant drag i SkåThe Precambrian crystalline basement in Skåne only outcrops in the large NW striking Horsts that are roughly parallel to the Tornquist Zone. In the south-easternmost part of the Linderödsåsen Horst in SE Skåne, the Stenshuvud porphyritic granitoids previously considered to be Palaeoproterozoic volcanic rocks, have been recently dated to 1458 Ma. This indicates that these rocks are coeval with the
