As requirements regarding energy efficiency are getting tougher, buildings in the arctic, as well as the rest of the world, need to be more energy efficient without compromising a good indoor climate. This article presents measured moisture supply and occupancy level in a Swedish arctic multi-family apartment block. Measurements were done over 1 year every 30 minutes in a building consisting of 51

Hip fracture risk is usually evaluated using dual energy X-ray absorptiometry (DXA) or quantitative computed tomography (QCT) which provide surrogate measures for proximal femoral strength. However, proximal femoral strength can best be estimated explicitly by combining QCT with finite element (FE) analysis. To evaluate this technique for predicting hip fracture in older men and women, we performe

The properties of beams of high energy protons accelerated during ultraintense, picosecond laser-irradiation of thin foil targets are investigated as a function of preplasma expansion at the target front surface. Significant enhancement in the maximum proton energy and laser-to-proton energy conversion efficiency is observed at optimum preplasma density gradients due, to self-focusing Of the incid

The Advanced GAmma Tracking Array (AGATA) is a European project to develop and operate the next generation gamma-ray spectrometer. AGATA is based on the technique of gamma-ray energy tracking in electrically segmented high-purity germanium crystals. This technique requires the accurate determination of the energy, time and position of every interaction as a gamma ray deposits its energy within the

Formulaic language represents a challenge to even the most proficient of language learners. Evidence is mixed as to whether native and non-native speakers process it in a fundamentally different way, whether exposure can lead to more nativelike processing for non-natives, and how L1 knowledge is used to aid comprehension. In this study we investigate how advanced non-native speakers process idioms

U ranijim istraživanjima ratnog nasilja, tokom rata u Bosni i Hercegovini, naglašavana je važnost priča ŽRTAVA ali fokus analize nije bio usmjeren na priče o ratnom nasilju, niti su analizirani poslijeratni intervjui kao produkt međuljudske interakcije. Ovom studijom pokušava se popuniti ta praznina analiziranjem priča osoba koje su preživjele rat u sjeverozapadnoj Bosni i Hercegovini. Prvi cilj s

Background: The merozoite surface protein 1 (msp1) is one of the most studied vaccine candidate genes in mammalian Plasmodium spp. to have been used for investigations of epidemiology, population structures, and immunity to infections. However methodological difficulties have impeded the use of nuclear markers such as msp1 in Plasmodium parasites causing avian malaria. Data from an infection trans

Popular Abstract in Swedish Kryptering kan användas när man vill hålla något viktigt meddelande hemligt, till exempel vid en bankbetalning på Internet. Men hur vet man att krypteringsalgoritmen (sättet att kryptera på) är tillräckligt säker? Hur vet man att ingen kan läsa vårt meddelande eller ändra i det så att, till exempel, en överföring av pengar från ett konto till ett annat går till någon heThe aim of this dissertation is to show some cryptanalytical results on a selection of stream ciphers. We have grouped theory and results into three main parts. The first part focuses on the FCSR-based constructions X-FCSR and F-FCSR-H v3. For the X-FCSR family of stream ciphers we perform a severe state recovery attack. This attack works for both X-FCSR-128 and X-FCSR-256. We then develop a gen

Near vacuum ultraviolet (UV) upconversion (UC) emissions with a spectral resolution of 1 nm, from the (6)G(J), D-6(J), I-6(J), P-6(J) levels of Gd3+ and the L-2(17/2), D-4(7/2), H-2(2)(9/2), D-2(5/2), (4)G(7/2), K-2(13/2), P-2(3/2) levels of Er3+, were observed under 974 nm laser excitation. Mechanism analyses illustrate that successive energy transfers (ETs) from Yb3+ to Er3+ generate UV UC radia

A dynamic mathematical model for simulating the coupled heat and moisture migration through multilayer porous building materials was proposed. Vapor content and temperature were chosen as the principal driving potentials. The discretization of the governing equations was done by the finite difference approach. A new experimental set-up was also developed in this study. The evolution of transient t

The role of informal venture capital in entrepreneurial process and economic development is increasingly recognized by scholars and policy-makers around the world. Much of the attention that this form of financing has received during the last couple of decades is due to its potential to bridge the regional equity gap. This study is concerned with regional distribution of informal venture capital a

Ingvar Kärnefelt hittade i somras den ovanliga lundgamandern på en till synes naturlig lokal i mellersta Halland.

Det område som idag kallas Strövområdet Arriesjön har bytt skepnad flera gånger under de senaste tre hundra åren. De processer och den historia som åstadkommit dessa förändringar speglas i de två historiska kapitlen. Men i det här kapitlet ger vi en översikt över områdets rent fysiska förändringar med hjälp av de flesta kartor och flygfoton som finns tillgängliga, från den första kartbilden 1702 t
