A novel high precision method measures the b-quark forward-backward asymmetry at the Z pole on a sample of 3,560,890 hadronic events collected with the DELPHI detector in 1992 to 2000. An enhanced impact parameter tag provides a high purity b sample. For event hemispheres with a reconstructed secondary vertex the charge of the corresponding quark or anti-quark is determined using a neural network
Parasympathetic denervation of the urinary bladder results in supersensitivity to muscarinic agonists and in bladder hypertrophy. In the present study, the effects of denervation on the muscarinic receptors in the rat bladder were investigated, using a receptor binding technique with (-)3H-QNB as radioligand. The density of muscarinic receptors was increased in denervated, hypertrophied bladders b
Magnetotransport in GaAs/AlAs/GaAs single-barrier heterostructures, incorporating unintentional donors in the barrier, is studied. Resonant tunneling is observed through the quasiconfined states in the AlAs layer which originate from the X-XY and X-Z conduction-band minima and through two distinct states of the donors bound to the X-XY and X-Z valleys. This allowes us to determine directly the bin
Popular Abstract in Swedish Vanligt viloelektrokardiogram (EKG) med 12 avledningar är ett av de mest använda redskapen för diagnostik av hjärtsjukdom. Tidigare forskning har visat att detta EKG ej är optimalt, men att nya EKG-metoder kan ge viktig tilläggsinformation. En metod som i flera tidigare studier visat sig innehålla diagnostisk potential är analys av de högfrekventa signalkomponenterna i The standard 12-lead electrocardiogram (ECG) is one of the most commonly used methods for diagnosing heart disease. Standard ECG is not always optimal, however, and new ECG methods can provide additional information. Analysis of high-frequency QRS components (HF-QRS) has been shown to increase the diagnostic performance of the ECG. Since the amplitudes of the HF-QRS are low compared with those vis
This paper reviews the current status of using remote sensing and process-based modeling approaches to assess the contemporary and future circumpolar carbon balance of Arctic tundra, including the exchange of both carbon dioxide and methane with the atmosphere. Analyses based on remote sensing approaches that use a 20-year data record of satellite data indicate that tundra is greening in the Arcti
Popular Abstract in Swedish I fem autopsistudier undersöktes humana käkledspreparat med tomografi (skiktröntgen), makroskopiskt (inspektion) och mikroskopiskt för förekomst av degenerativa (nedbrytande) förändringar. Speciellt undersöktes förekomst av erosiva förändringar i benet samt förändringar i den förkalkade broskzonen (skiktet mellan mjukbrosk och ben). Det förkalkade brosket var i normalaIn five autopsy specimen studies human temporomandibular joints were investigated by conventional tomography, macroscopy, and microscopy for degenerative changes, in particular erosive hard-tissue changes.In the microscopical evaluation special attention was paid to the calcified cartilage. The calcified cartilage was outlined by a flat or gently undulating basophilic tidemark and an irregular os
The light response of a BGO crystal has been measured for particles Z = 1-8, A = 1-16 in the energy range similar to2-60 A MeV. The reaction products are identified by a DeltaE(Si) - E(Sci/PD) telescope, The position of the jump in the value of the signal from the PD at the punch-through points is used to calibrate both the DeltaE(Si) and E(Sci/PD) scales in MeV. The dependence of the light output
A total of six high-resolution FT-IR spectra for trans-glyoxal-d(2), trans-glyoxal-d(1) and trans-glyoxal-C-13(2) were recorded with a resolution ranging from 0.003 to 0.004 cm(-1). By means of a simultaneous ground state combination difference analysis for each of these isotopologues using the Watson Hamiltonian in A-reduction and I-r-representation the ground state rotational constants are obtai
1 In the present study, the inhibitory effects of the selective beta 2-adrenoceptor agonists, salmeterol, formoterol and salbutamol, have been investigated on contractions of ferret trachea induced both by endogenous and exogenous acetylcholine. The aim of the study was to evaluate quantitative and/or qualitative differences in response which may indicate both pre-and post-junctional sites of acti
We consider possible schemes for the resonance-enhanced two-photon ionization (RETPI) of Ne and Ar atoms under the action of bichromatic radiation of intense resonance lines of HI, HeI, and HeII in a radiation-rich astrophysical plasma. The ionization rate is comparable to or exceeds the recombination rate in rarified astrophysical plasma, which leads to the accumulation of singly ionized ions wit
Popular Abstract in Swedish Bakgrund Hur gatunätet ser ut och planera's i städer påverkar förutom trafikarbetet även hur bilister kör. Körbeteendet i form av körmönster, d.v.'s. hastighet's- och accelerationsprofiler, påverkar i sin tur såväl bränsleförbrukning som avgasemissionsfaktorer. En betydande del av trafiken sker inom tätorter där såväl luftkvalitet som totala utsläpp är av betydelse. ÄvThe planning and design of street networks in cities influence driving behaviour and give rise to variations in driving patterns (i.e., speed and acceleration profiles) that affect exhaust emissions and fuel consumption. The primary objective of this study has been to use real-life driving patterns to investigate how the characteristics of street networks influence fuel consumption and vehicular e
Type 2 diabetes (T2D) is a serious condition of growing proportions. Developing via an increasing imbalance between insulin sensitivity in the peripheral tissues and insulin release from pancreatic beta-cells, it ultimately renders the individual incapable of regulating the blood glucose concentration, e.g. after a meal. The increased prevalence of T2D is associated with an increase in the prevale
Eutrophication of the Baltic Sea has potentially increased the frequency and magnitude of cyanobacteria blooms. Eutrophication leads to increased sedimentation of organic material, increasing the Extent of anoxic bottoms and subsequently increasing the internal phosphorus loading. In addition, the hypoxic water volume displays a negative relationship with the total dissolved inorganic nitrogen poo
A molecular understanding of volatile anesthetic mechanisms of action will require structural descriptions of anesthetic–protein complexes. Porcine odorant binding protein is a 157 residue member of the lipocalin family that features a large β-barrel internal cavity (515 ± 30 Å3) lined predominantly by aromatic and aliphatic residues. Halothane binding to the β-barrel cavity was determined using f
Aims: This cohort study on urban middle-aged men investigates the association between the use of analgesics and hypnotics, self-rated health (SRI-I) and disability pension. Methods: Five birth-year cohorts of middle-aged, urban, Swedish men were invited to a screening programme and were followed for approximately 11 years. Results: Out of all the subjects (n = 5798), 12.4% received a disability pe
