A well-ordered surface oxide grown on Fe(110) has been studied using scanning tunneling microscopy (STM), low energy electron diffraction, low energy electron microscopy, and core level photoelectron spectroscopy. The iron oxide film exhibits wide terraces and is formed after exposure to 100-1000 L at 1 x 10(-6) mbar O-2 and 400 degrees C. Two domains, mirror symmetric in the Fe(110)-lattice mirro
Softening of dried Vangueria infausta using maltodextrin and sucrose was investigated experimentally. The pulp of V. infausta was dried in a convective dryer, the influence of drying temperature as well as relationship between water content and water activity were examined. In this study, 48 samples of V. infausta pulp, with and without maltodextrin or sucrose, were dried at air temperatures of 60
Context: Prostate cancer (PCa) is a clinically heterogeneous disease with marked variability in patient outcomes. Molecular characterization has revealed striking mutational heterogeneity that may underlie the variable clinical course of the disease. Objective: In this review, we discuss the common genomic alterations that form the molecular basis of PCa, their functional significance, and the pot
Exposure of metazoan organisms to hypoxia engages a metabolic switch orchestrated by the hypoxia-inducible factor 1 (HIF-1). HIF-1 mediates induction of glycolysis and active repression of mitochondrial respiration that reduces oxygen consumption and inhibits the production of potentially harmful reactive oxygen species (ROS). Here, we show that FoxO3A is activated in hypoxia downstream of HIF-1 a
PURPOSE: Computer-assisted laparoscopic surgery (CALS) in children is increasingly used and has proven to be feasible and safe. However, its full potential remains unclear and clinical comparative studies hardly exist. The aim of this study was to prospectively evaluate our experience with CALS for performing retroperitoneal nephrectomies in children when compared with controls undergoing open sur
Pervasive computing is a vision about computers blending into the background, being there to assist us when we need them, but not requiring constant attention. The vision covers scenarios in the home, at work, and out in the street, and builds on the ongoing development towards an increasing number of embedded computers with network connectivity. The thesis presents the assembly as a lightweight
In the face of pressures to expand the rule of law, in 2004, Japan introduced a new law school system in order to produce more and better qualified lawyers. This article explains why the new law school system solution was selected from among other alternatives such as reforming the national bar exam, abolishing mandatory legal training, reforming existing legal education, or redefining the jurisdi
Low grade systemic inflammation (LGSI) as well as androgen deficiency has in older men been associated with several pathologies, including cardiovascular disease (CVD). We wanted to investigate whether low testosterone levels are linked to biomarkers of LGSI already in young age, before any concurrent manifestations of CVD or other systemic diseases.
Myth, from the Greek mythos: “Mar-velous narration situated outside historic time told by divine or heroic characters. Often interprets the world’s origin or great human events”. The dragon, ex-cept for in China, has always been a symbol of “evil”, but, at the same time, the fire and power represented by the dragon are essential elements for hu-mankind. The modern city, symbolically under-stoo
Aim To predict mortality risk and life expectancy for patients with Type 2 diabetes after a major diabetes-related complication. Methods The study sample, taken from the Swedish National Diabetes Register, consisted of 20 836 people with Type 2 diabetes who had their first major complication (myocardial infarction, stroke, heart failure, amputation or renal failure) between January 2001 and Decemb
A search for the flavour-changing neutral-current decay is presented. Data collected by the ATLAS detector during 2012 from proton-proton collisions at the Large Hadron Collider at a centre-of-mass energy of root s = 8 TeV, corresponding to an integrated luminosity of 20.3 fb(-1), are analysed. Top-quark pair-production events with one top quark decaying through the t -> qZ (q = u,c) channel and t
The centenary of the outbreak of the First World War in 1914 has spurred a lively popular and academic debate about the conflict's role in shaping the twentieth century and the European present. This article examines the war from a slightly different perspective, taking as its point of departure the impact of the war on neutral Scandinavia and its place in contemporary Scandinavian historical cons
We report on recent studies of the phenomenon of color decoherence in jets in QCD media. The effect is most clearly observed in the radiation pattern of a quark-antiquark antenna, created in the same quantum state, traversing a dense color deconfined plasma. Multiple scattering with the medium color charges gradually destroys the coherence of the antenna. In the limit of opaque media, this ultimat
Artikel om mottagandet av Röde Orm från 1940-talet till våra dagar samt en analys av romanens mediering, det vill säga de nya gestaltningar som den fått i form av till exempel spelfilm och tecknad serie.
One of the primary goals of the 700MeV MAX III synchrotron radiation source is to test and gain experience with new magnet and accelerator technology. Each magnet cell is machined out of two solid iron blocks that are then sandwiched together after coil and quadrupole installation. The MAX III ring makes extensive use of combined function magnets to obtain a compact lattice. In order to obtain fle
The principle of extended producer responsibility (EPR) has been a policy paradigm behind the development of waste policies in the European Union including the End-of-Life Vehicle (ELV) Directive (2000/53/EC). This study compares and explains the environmental effectiveness of the ELV programmes in the United Kingdom and in Sweden between 1990 and 2005, using a framework that integrates the Dutch
