The purpose of this study was to increase the understanding of, and develop a model to explain, interrelations between purchasing strategies carried out by buyers within vaccine supply chains for developing countries and their buyer-supplier power structure. In the humanitarian aid context, availability of required goods (e.g. health related products) at the right time and place is of vital import

The university programmes are basically nationally based, developed from the historical needs of specific need of a society. The Bologna process is challenging the educational market mainly at post-graduate level. The exchange of students is still limited to a reduced number of curious and ambitious persons, many with a high interest for cultural exchange – the ‘exotic dimension’. Individual caree

Although ethnic conflicts are an acute international problem, researchers in international relations have conducted surprisingly little research in this area. The aim with this study is to analyze one aspect of ethnic conflicts, how the elites representing ethnic groups act to make the great powers legitimize their own demands, and delegitimize the demands of the enemy by adducing to norms. In the

The cerebrospinal fluid (CSF) biomarkers amyloid-beta (A beta)(1-42), T-tau, and P-tau have good diagnostic accuracy for clinically diagnosed Alzheimer's disease (AD). However, in multi-center studies, the predictive values of the CSF biomarkers have been lower, possibly due to differences in procedures for lumbar puncture and CSF handling and storage, and to differences in patient populations, cl

OBJECTIVES: To design and validate a scoring system for tomosynthesis (digital tomography) in pulmonary cystic fibrosis. METHODS: A scoring system dedicated to tomosynthesis in pulmonary cystic fibrosis was designed. Three radiologists independently scored 88 pairs of radiographs and tomosynthesis examinations of the chest in 60 patients with cystic fibrosis and 7 oncology patients. Radiograph

Detailed (222)radon (Rn-222) flux maps are an essential pre-requisite for the use of radon in atmospheric transport studies. Here we present a high-resolution Rn-222 flux map for Europe, based on a parameterization of Rn-222 production and transport in the soil. The Rn-222 exhalation rate is parameterized based on soil properties, uranium content, and modelled soil moisture from two different land

A modification of the Roe scheme called L2Roe for low dissipation low Mach Roe is presented. It reduces the dissipation of kinetic energy at the highest resolved wave numbers in a low Mach number test case of decaying isotropic turbulence. This is achieved by scaling the jumps in all discrete velocity components within the numerical flux function. An asymptotic analysis is used to show the correct

PET with F-18-choline (F-18-FCH) is used in the diagnosis of prostate cancer and its recurrences. In this work, biodistribution data from a recent study conducted at Skane University Hospital Malmo were used for the development of a biokinetic and dosimetric model. Methods: The biodistribution of F-18-FCH was followed for 10 patients using PET up to 4 h after administration. Activity concentration

Despite the importance of regioselective reductive openings of cyclic acetals, mechanistic details are scarce. In this study 4,6-O-benzylidene acetals were used as model compounds for deciphering the mechanism of regioselective openings using a variety of reducing agents. Competitive isotopic studies aiming at primary and secondary isotope effects, as well as an electron-deficient substrate, were

Type 2 diabetes carries a risk for hypoglycemia, particularly in patients on an intensive glucose control plan as a glucose-lowering strategy, where hypoglycemia may be a limitation for the therapy and also a factor underlying clinical inertia. Glucose-lowering medications that increase circulating insulin in a glucose-independent manner, such as insulin and sulfonylurea therapy, are the most comm

Seven strongly supported clades, characterised by molecular, morphological and anatomical characters are described as new genera: Eilifdahlia, Elenkiniana, Franwilsia, Huneckia, Marchantiana, Mikhtomia and Yoshimuria. Two new species, Eilifdahlia wirthii from South Africa and Marchantiana maulensis from Chile are described, illustrated and compared with closely related taxa.

Complement convertases are enzymatic complexes that play a central role in sustaining and amplification of the complement cascade. Impairment of complement function directly or indirectly leads to pathologic conditions including higher infection rate, kidney diseases, autoimmune- or neurodegenerative diseases and ischemia-reperfusion injury. An assay for direct measurement of activity of the conve

Soot, which is produced from biomass burning and the incomplete combustion of fossil and biomass fuels, has been linked to regional and global climate change and to negative health problems. Scientists measure the properties of soot using a variety of methods in order to quantify source emissions and understand its atmospheric chemistry, reactivity under emission conditions, interaction with solar
