The regulation of a K+ current activating during oscillatory electrical activity (I-K,I-slow) in an insulin-releasing,beta-cell was studied by applying the perforated patch whole-cell technique to intact mouse pancreatic islets. The resting whole-cell conductance in the presence of 10 mm glucose amounted to 1.3 nS, which rose by 50% during a series of 26 simulated action potentials. Application of

We report on likely mixed paternity in a natural population of snow skinks (Niveoscincus mirolepidoms) from alpine Tasmania, Australia. This species is nonterritorial and males guard females after copulation, Suggesting that guarding behavior has evolved to prevent rival mating of still-receptive females. To what degree does this mate-guarding prevent rival copulations? We sampled gravid females a

Abstract in French Cet article a deux objectif. À un premier niveau, nous présentons un survol de quatre aspects du DP français et leur acquisition par des apprenants adultes suédophones, à savoir l’existence d’un stade de noms dits « nus », le statut syntaxique de l’article défini, le placement de l’adjectif et l’accord en genre. À un deuxième niveau, nous souhaitons illustrer une méthode de travThis article has two objectives. At a first level we present an overview of four aspects of the French DP and its acquisition by adult Swedish speaking learners, namely the existence of a bare noun stage, the syntactic status of the definite article, the placement of the adjective and gender agreement. At a second level, we wish to illustrate a method in Research on Language Acquisition which is i

The risk of seizure recurrence within the first year of life was evaluated in infants with neonatal seizures diagnosed with a combination of clinical signs, amplitude-integrated electroencephalogram (EEG) monitoring, and standard EEG. Fifty eight of 283 (4.5%) neonates in tertiary level neonatal intensive care had seizures. The mortality in the infants with neonatal seizures was 36.2%. In 31 survi

In May 2003 Lund University, Sweden, ordered a new AMS facility from National Electrostatics Corp. (NEC), Wisconsin. The system is the first low energy, open air, single stage AMS system (SSAMS). The machine is equipped with a dual ion source sequential injector, which allows measurements of carbon with the masses 12, 13 and 14. The machine operates at 250 kV with the gas stripper, high energy mag

Deep-inelastic e(+/-) p scattering at high squared momentum transfer Q(2) up to 30 000 GeV2 is used to search for eq contact interactions associated to scales far beyond the HERA centre of mass energy. The neutral current cross section measurements dsigma / dQ(2), corresponding to integrated luminosities of 16.4 pb(-1) of e(-) p data and 100.8 pb(-1) of e(+) p data, are well described by the Stand

A general method is presented for patient-specific 3-dimensional absorbed dose calculations based on quantitative SPECT activity measurements. METHODS: The computational scheme includes a method for registration of the CT image to the SPECT image and position-dependent compensation for attenuation, scatter, and collimator detector response performed as part of an iterative reconstruction method. A

Measurements are presented of differential dijet cross sections in diffractive photoproduction (Q(2) < 0.01 GeV2) and deep-inelastic scattering processes (DIS, 4 < Q2 < 80 GeV2). The event topology is given by ep -> eXY, in which the system X, containing at least two jets, is separated from a leading low-mass baryonic system Y by a large rapidity gap. The dijet cross sections are compared with NLO

Popular Abstract in Swedish Denna avhandling presenterar en metod som kan hantera generella tjocka frekvensselektiva strukturer (FSS). Metoden är baserad på modanpassning och finita elementmetoden (FEM). Avhandlingen är en sammanläggningsavhandling och består av en introduktion som följs av fem vetenskapliga artiklar. Frekvensselektiva strukturer fungerar som filter för elektromagnetiska vågor, sThis thesis presents a new method that can handle a general thick Frequency Selective Structure (FSS), that consists of an arbitrary number of aperture layers and dielectric layers. The method is based on the Mode Matching Technique (MMT) and the finite element method (FEM). The thesis consists of a General Introduction and five scientific papers. The General Introduction gives an overview of fil

Previous experimental studies have shown positive effects of hyperbaric oxygen treatment in the early regeneration phase in the first few days following a nerve injury. In this study, functional effects of hyperbaric oxygen treatment were studied in 2 series of rats after an injury to the sciatic nerve - a standardized crush injury and nerve transection and repair, respectively. Postoperatively th

Lead is one of the poisonous elements for de-NOx catalysts especially in the case of municipal waste incineration plants. Samples of a commercial selective catalytic reduction catalyst were impregnated with different amounts of Pb(NO3)(2), and their catalytic activities were studied. The XPS and SEM analysis showed higher lead concentration on the outer surface of the monolith than on the inside o

Dizziness and subjective balance disturbances are common complaints in cervical pain syndromes. We assessed balance function with posturography using vibration-induced and galvanically-induced body sway in consecutive patients (n = 116) with cervico-brachial pain syndrome of more than 3 months' duration. A total of 83% of the patients showed signs of cervical root compression on MRT scans. The inc

We have studied the spatial structure and electronic levels of clusters of the molecule CH3Br to investigate the effects of molecular polarity on these properties. Analysis of the core level photoclectron spectra of initially neutral CH3Br clusters shows that the C 1 s(-1) state has a 30% larger binding energy shift between free molecules and clusters than the Br 3d(-1) state. This difference is a

Strained nanowires with varying InAs/InP core/shell thicknesses were grown using Chemical Beam Epitaxy. Microphotoluminescence spectroscopy, performed at low temperature, was then used to study the optical properties of single wires. Emission from the InAs core was observed and its dependence on the shell thickness/core diameter ratio was investigated. We found that it is possible to tune the emis
