Why are some states more corrupt than others? Drawing on the literature on governance in parliamentary democracies, we suggest that the degree of corruption depends on the ability of key political actors to control ministers who have been delegated power. We argue that the Prime Minister has incentives to limit corruption within the cabinet and has the ability to do so when there are certain “cont

Background: Topical oestrogen and manual separation are the main treatments for labial adhesions. The aim was to evaluate treatment of labial adhesions and compare the outcome of topical oestrogen treatment with that of manual separation. Method: All girls aged 0-12 years admitted to a tertiary centre for paediatric surgery for labial adhesions were included. The study design was dual: The first p

Objective To investigate whether oral fluoroquinolone use is associated with an increased risk of aortic aneurysm or dissection. Design Nationwide historical cohort study using linked register data on patient characteristics, filled prescriptions, and cases of aortic aneurysm or dissection. Setting Sweden, July 2006 to December 2013. Participants 360 088 treatment episodes of fluoroquinolone use (

This paper describes an expedition to map a first century B.C. ship wreck off the coast of the Greek island of Antikythera using an Autonomous Underwater Vehicle (AUV) equipped with a high-resolution stereo imaging system. The wreck, first discovered in 1900, has yielded a wealth of important historical artefacts from two previous interventions, including the renowned Antikythera mechanism. The de

The processing of emotional signals usually causes an increase in pupil size, and this effect has been largely attributed to autonomic arousal prompted by the stimuli. Additionally, changes in pupil size were associated with decision making during non-emotional perceptual tasks. Therefore, in this study we investigated the relationship between pupil size fluctuations and the process of emotion rec

Sound and radio can be used to estimate the distance between a transmitter and a sender by correlating the emitted and received signal. Alternatively by correlating two received signals it is possible to estimate distance difference. Such methods can be divided into methods that are robust to noise and reverberation, but give limited precision and sub-sample refinements that are sensitive to noiseSound and radio can be used to estimate the distance between a transmitter and a sender by correlating the emitted and received signal.

Different starchy foods are frequently consumed in the Mexican diet. Some of them were developed by Pre-Columbian Mesoamerican civilizations. Until today, common beans (Phaseolus vulgaris), tortillas made with maize (Zea mays) and related maize-based products are some of the main staple foods. Additionally, wheat-based foods are also important starch sources, incorporated in different dishes. This

Mixed pathologies of α-synuclein, β-amyloid and tau are relatively common in Parkinson's disease (PD) and Dementia with Lewy Bodies (DLB). We therefore wanted to study the retention patterns of 18F-AV-1451 in PD, PD-dementia (PDD), and DLB. To do this 44 healthy controls, 11 non-demented patients with PD, 18 patients with PDD, and six patients with DLB underwent MRI and 18F-AV-1451 PET scanning an

Sulfite oxidase is a mononuclear molybdenum enzyme that oxidises sulfite to sulfate in many organisms, including man. Three different reaction mechanisms have been suggested, based on experimental and computational studies. Here, we study all three with combined quantum mechanical (QM) and molecular mechanical (QM/MM) methods, including calculations with large basis sets, very large QM regions (80

Politikens legitima parter bör ta avstånd från oetiska metoder, statuera goda exempel och redovisa en etik för digitalt kampanjande. Det kommer att främja valrörelsen, den öppna debatten och demokratin, skriver Jonas Andersson Schwarz, Stefan Larsson och Anders Mildner.

Increasing the turbine inlet temperature can enhance the thermal efficiency of a gas turbine. Therefore, modern gas turbines operate at a relatively high level of temperature and endure heavy thermal load. It is important to ensure the modern gas turbine works at a high performance and safe condition. Advanced cooling techniques are implemented in the gas turbine system. In the current study, effe

This work focuses into the combustion behaviour of single wheat straw particles with the aim of providing a quantitative description of the particle burning process from ignition to the early stages of the char oxidation. The single particles, in the size range 224–250 µm, were injected upward into a confined region with hot combustion products, produced by a flat flame McKenna burner, with a mean

A counter-flow reactor setup was designed to investigate the gas-phase sulfation and homogeneous nucleation of potassium salts. Gaseous KOH and KCl were introduced into the post-flame zone of a laminar flat flame. The hot flame products mixed in the counter-flow with cold N2, with or without addition of SO2. The aerosols formed in the flow were detected through Mie scattering of a 355 nm laser bea

Starch has undisputable importance in foods both from the nutritional—mainly energy—related‐and technological viewpoints. Different types of starch derivatives, including a number of hydrolysis products, are frequently used as food ingredients, especially because of the particular physicochemical properties they may confer. In recent years, certain hydrolytic derivatives of starch, such as maltode

The coexistence of ecologically similar species might be counteracted by ecological drift and demographic stochasticity, both of which erode local diversity. With niche differentiation, species can be maintained through performance trade-offs between environments, but trade-offs are difficult to invoke for species with similar ecological niches. Such similar species might then go locally extinct d

BACKGROUND: Pulses represent an important source of protein, as well as digestible and indigestible carbohydrates. Little information is available on the indigestible carbohydrates and antioxidant capacity of legume seeds. The cooked seeds of three pulses (black bean, chickpea and lentil) were evaluated for their indigestible fraction (IF), polyphenols content, antioxidant capacity and in vitro fe
