It has been argued that the fundamental cause of Africa’s current relative poverty is a lack of pro-growth institutions deriving either from the colonial system, the period of slavery, or from particular geographic or population characteristics. This article takes a fresh look at estimates of African country incomes. It subjects the available datasets to tests of accuracy, reliability, and volatil

Background Obesity is linked to cardiovascular diseases and increasingly common in type 1 diabetes mellitus (T1DM) since the introduction of intensified insulin therapy. Our main aim was to explore associations between obesity and depression, anxiety, alexithymia and self-image measures and to control for lifestyle variables in a sample of persons with T1DM. Secondary aims were to explore associat

Popular Abstract in Swedish Idag har kravet på kortare ledtider i bilindustrin dramatiskt ökat behovet av effektivare utvecklingsmetoder vid varje steg i processutvecklingskedjan. För att minska de långa ledtiderna för framtagning av ett formningsverktyg har man introducerat Finita Element (FE) simulering av formningsprocessen. Även om FE-simulering används inom bilindustrin idag finns fortfarandeToday, shortened lead-times in the automotive industry have dramatically increased the need for more efficient development methods at every stage of the process development chain. In order to decrease the long lead-time for producing a forming tool, sheet-metal-forming simulation was introduced. Even though sheet-metal-forming simulation is widely used in the automotive industry today, there are s

The 19th century rise of history as an academic discipline set new standards for acceptable methods of writing history. This greatly influenced the opinions historians held of older historical works, such as the Historia de omnibus Gothorum Sueonumque regibus (History of all the Kings of the Goths and the Swedes) by the Swedish archbishop Johannes Magnus (1488-1544). The work has been criticised f

Tropical forest soils are a significant source for N2O and NO. Current estimates of N2O and NO emissions areuncertain due to the limited number of fieldmeasurements and model input data. Furthermore, considerable spatialand temporal variability exists due to variation of soil properties, vegetation characteristics and meteorology.Weused a process-based model (ForestDNDC-tropica) to estimate N2O an

High-resolution core-level spectroscopy is used in combination with low-energy electron diffraction (LEED) and photoelectron diffraction to identify the adsorption sites for three different coadsorbed phases consisting of ordered overlayers of oxygen coadsorbed with CO on the Rh(111) single-crystal surface. The three ordered overlayer structures, which may be denoted as 2O + CO/Rh(111), O + CO/Rh(

Objective: To determine the within- and between-patient variability in the concentrations of synovial fluid, serum and urine markers of joint tissue metabolism in a cohort of patients with knee pain and cartilage changes consistent with early-stage knee osteoarthritis. Design: Samples of synovial fluid, serum, and urine were obtained from 52 patients on eight different occasions during 1 year, as

Objective: To characterize meal patterns across ten European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) calibration study. Design: Cross-sectional study utilizing dietary data collected through a standardized 24 h diet recall during 1995–2000. Eleven predefined intake occasions across a 24 h period were assessed during the interview. In the p

Algorithms for Massive MIMO uplink detection typically rely on a centralized approach, by which baseband data from all antennas modules are routed to a central node in order to be processed. In case of Massive MIMO, where hundreds or thousands of antennas are expected in the base-station, this architecture leads to a bottleneck, with critical limitations in terms of interconnection bandwidth requi

Climate change, energy security and air pollution are all motivators for the further development of fuel cells. A volume of fluid approach was used to investigate the impact of dynamic contact angle boundary conditions (Kistler model), mainly at the gas diffusion layer surface but also at the channel wall, of a polymer electrolyte fuel cell gas channel. From this study, it is clear that a dynamic

When the Soviet Union invaded Hungary in 1956, a wave of streetlevel anti-communist protests swept overWestern Europe. These often violent protest were directed against Soviet embassies, domestic communist parties and communistnewspapers. The wave also reached Scandinavia, where the 1950’s otherwise is considered a calm and peaceful period. In Denmark and Sweden, a number of antiSoviet and anti-co

We consider a multipair two-way relay communication network, where pairs of user devices exchange information via a relay system. The communication between users employs time division duplex, with all users transmitting simultaneously to relays in one time slot and relays sending the processed information to all users in the next time slot. The relay system consists of a large number of single ant

We investigate the single-file dynamics of a tagged particle in a system consisting of N hardcore interacting particles (the particles cannot pass each other) which are diffusing in a one-dimensional system where the particles have different diffusion constants. For the two-particle case an exact result for the conditional probability density function (PDF) is obtained for arbitrary initial partic

Microembolization is common after coronary interventions, and therefore this MRI study aimed to quantify the effect of coronary microembolization on left ventricular (LV) function. The left anterior descending artery (LAD) was selectively catheterized in an XMR suite (Philips Medical Systems, Best, The Netherlands) in eight pigs to deliver MR contrast media to measure the LAD territory using first

Renovascular disease as cause of end-stage renal disease has become more frequent during the last decade. In order to minimize the need for dialysis treatment non-invasive screening for the disease is needed. However, both ultrasonic duplex scanning and renal scintigraphy are not sufficient for detection of all stenosis. Furthermore, there is little data on non-invasive tests in patients with rena

Heterogeneous patterns of genomic differentiation are commonly documented between closely related populations and there is considerable interest in identifying factors that contribute to their formation. These factors could include genomic features (e.g., areas of low recombination) that promote processes like linked selection (positive or purifying selection that affects linked neutral sites) at

Anorexia nervosa is associated with bone loss during adulthood, but may also delay skeletal growth and mineral accrual during growth. We asked the following questions. 1) Is anorexia nervosa associated with reduced bone size and reduced volumetric bone mineral density (vBMD)? 2) Is estrogen replacement therapy (ERT) or recovery from anorexia nervosa associated with normal bone size and vBMD?
