A survey of biting midges of the genus Culicoides Latreille, 1809 (Diptera: Ceratopogonidae) in NE Bulgaria, with respect to transmission of avian haemosporidians
This study presents data from a molecular survey of the species of the genus Culicoides from the region of Kalimok Field Station (NE Bulgaria) and haemosporidian parasites occurring in them in order to investigate the host-parasite specificity of haemosporidians to their dipteran vectors. The identification of Culicoides spp. was carried out by morphological and molecular-genetic methods. We colle
Comparison of two strategies to reduce ventricular pacing in pacemaker patients
Background: Managed Ventricular Pacing (MVP) and Search AV+ (SAV+) are two pacing algorithms designed to reduce ventricular pacing, MVP promotes conduction by operating in AAI/R mode with backup ventricular pacing during atrioventricular block (AVB). SAV+ operates in DDD/R mode with a nominal AV extension of 290 ms during atrial sensing and 320 ms during atrial pacing. The reduction in ventricular
Rör inte min pension! Om värdet av stabila spelregler även i nedgång.
Den kraftiga börsnedgången under 2008 leder till att balanseringen i det allmänna pensionssystemet aktiveras 2010. Inkomstpensionerna skulle sänkas med ca 3,5 procent. Men 2010 är valår och regeringen har valt att ändra beräkningsmetoden.
System Identification in GSM/EDGE Receivers Using a Multi-Model Approach
Model order selection is an important element in system identification. It is well known that common model order selection methods such as Akaike’s information criterion (AIC) and Bayesian’s information criterion (BIC) neglect relevant information that is available in models of order different from the one chosen. In this paper the model order selection problem for receivers similar to those found
Lower Limb Amputation in Patients with Vascular Disease
Popular Abstract in Swedish Antalet personer som är amputerade ovanför tålederna i Sverige kan uppskattas till mellan 5000 och 5500. (ca 0.06 % av befolkningen). Största delen av dessa är amputerade pg.a. av kärlsjukdom (≈ 80 %). Antalet årligen nytillkomna benamputerade i Sverige kan uppskattas till mellan 1000-1100 och mindre än 5 % av dessa fall är relaterade till andra orsaker, t.ex. trauma elThe current prevalence of persons amputated at transmetatarsal level or higher in Sweden can be estimated to be between 5000 and 5500 persons (approx. 0.06 % of the population). The majority of these are patients with vascular disease (≈ 80%). In Sweden between 1000 and1100 new amputees can be expect every year. Less than 5% of all amputations will be related to causes other than vascular disease.
Effects of the DPP-4 Inhibitor Vildagliptin on Incretin Hormones, Islet Function, and Postprandial Glycemia in Subjects with Impaired Glucose Tolerance
Objective: This study was conducted to determine the effects of vildagliptin on incretin hormone levels, islet function, and postprandial glucose control in subjects with impaired glucose tolerance (IGT). Research Design and Methods: A 12-week double-blind, randomized, parallel-group study comparing vildagliptin (50 mg qd) and placebo was conducted in 179 subjects with IGT (2-h glucose= 9.1 mmol/l
Fast and Reliable Two-View Translation Estimation
It has long been recognized that one of the fundamental difficulties in the estimation of two-view epipolar geometry is the capability of handling outliers. In this paper, we develop a fast and tractable algorithm that maximizes the number of inliers under the assumption of a purely translating camera. Compared to classical random sampling methods, our approach is guaranteed to compute the optimal
Radioactivity Exploration from the Arctic to Antarctica. Part 5: The Tundra-94 expedition
The joint Swedish-Russian “Tundra Ecology-94” expedition during 1994 used the large Russian ice-breaking research vessel R/V Akademik Fedorov a platform and went along a coastline of 3500 km-from the Kola Peninsula 10°E to Kolyuchinskaya Bay 173°E. Radioactivity in air, seawater and sediment was explored at various locations along the route. The average of 7Be activity concentration in air over th
Investigation of Microstrip Antenna Array Stacked Structure Realized on LTCC for 60 GHz Band
This paper presents the 16-element antenna array with parasitic microstrip antenna single element. Antenna designed to operate at 60 GHz and its structure based on low-temperature cofired ceramic (LTCC) substrate. Gain more then 18 dBi and return loss bandwidth about 20% were obtained after antenna geometry parameters optimization
Characterization of human dopaminergic neurons in the developing mesencephalon and upon differentiation of stem cells- for replacement therapy in Parkinson´s disease
Popular Abstract in Swedish Hjärnan är ett av människans viktigaste organ och är det centra som styr våra känslor, minnen och sociala färdigheter. Hjärnan är också det organ som signalerar till musklerna i kroppen att utföra rörelser. När en person drabbas av Parkinsons sjukdom minskar signaleringen till musklerna, vilket medför att det blir svårt att röra sig och stelhet uppstår. Sjukdomen beror Cell-replacement therapy is a promising approach for treating patients with Parkinson ́s disease (PD). For this purpose, there is a need for developing a protocol that can generate high numbers of human transplantable mesencephalic dopaminer- gic (mesDA) neurons. For decades, studies have therefore been made in mouse and other model organisms in order to elucidate key-factors that can be used for
What successful branding looks like: a managerial perspective
Purpose - The purpose of this paper is to develop an understanding of the ways in which food companies can work with branding to perform better in the market. The authors achieve this purpose by comparing how different managers of food brands prioritise and evaluate their brands, in relation to a theoretical ideal framework. Design/methodology/approach - A survey of 77 managers of domestic and int
Carrier Frequency Offset and I/Q Imbalance Compensation for MB-OFDM Based UWB System
Tracking the shape-dependent sintering of platinum-rhodium model catalysts under operando conditions.
Nanoparticle sintering during catalytic reactions is a major cause for catalyst deactivation. Understanding its atomic-scale processes and finding strategies to reduce it is of paramount scientific and economic interest. Here, we report on the composition-dependent three-dimensional restructuring of epitaxial platinum-rhodium alloy nanoparticles on alumina during carbon monoxide oxidation at 550 K
On the suitability of carbon nanotube forests as non-stick surfaces for nanomanipulation
A carbon nanotube forest provides a unique non-stick surface for nanomanipulation, as the nanostructuring of the surface allows micro- and nanoscale objects to be easily removed after first being deposited via a liquid dispersion. A common problem for smooth surfaces is the strong initial stiction caused by adhesion forces after deposition onto the surface. In this work, carbon nanotube forests fa

Some open questions in TDDFT: Clues from lattice models and Kadanoff-Baym dynamics
Two aspects of TDDFT, the linear response approach and the adiabatic local density approximation, are examined from the perspective of lattice models. To this end, we review the DFT formulations on the lattice and give a concise presentation of the time-dependent Kadanoff-Baym equations, used to asses the limitations of the adiabatic approximation in TDDFT. We present results for the density respo
Growth and characterization of superconducting beta-FeSe type iron chalcogenide nanowires
We have grown highly crystalline beta-FeSe type iron chalcogenide nanowires (NWs) by annealing thin film that is prepared by a pulsed laser deposition method. Three kinds of NWs with compositions of Fe0.8Se, Fe0.88Se0.32Te0.68 and Fe0.88Te0.91S0.09 have been prepared and carefully characterized by a high-resolution transmission electron microscope (HRTEM). The NWs reveal ideal tetragonal structure
