In the reaction e(+)e(-) -> WW -> (q(1) (q) over bar (2))(q(3)(q) over bar (4)) the usual hadronization models treat the colour singlets q(1)(q) over bar (2) and q(3)(q) over bar (4) coming from two W bosons independently. However, since the. nal state partons may coexist in space and time, cross-talk between the two evolving hadronic systems may be possible during fragmentation through soft gluon
This paper reflects on the debate which followed the publication of my paper “The Identity Crisis of a Stepchild” which appeared in Retfærd 1998: 21(2). Its ultimate aim is not to meet the criticism directed at it, but rather to take debate on the disciplinary shortcomings of sociology of law to a higher level of sociological analysis.
Analytic expressions for the exact bit error probabilities of rate R = 1/2, memory m = 2 convolutional encoders are derived for a maximum-likelihood (ML) decoder and transmission over the binary-symmetric channel (BSC). The resulting expressions are rational functions of the crossover probability of the BSC. In addition to classical nonsystematic encoders without feedback, we consider also recursi
The fouling tendency, due to adsorption on the pore walls, of two pairs of modified and unmodified ultrafiltration membranes, with similar observed retentions determined by dextran and gel permeation chromatography, was studied. The membranes investigated were made of modified and unmodified polyaramide (PA) and modified and unmodified polyvinylidene fluoride (PVDF). The PVDF membrane was surface-
OBJECTIVE Serum Hsp60 and anti-Hsp65 antibody levels are raised in subjects with borderline hypertension, and there is an association between circulating Hsp60 levels and early atherosclerosis. Given the recognized relationship between hypertension and atherosclerosis, this study determined heat shock protein and heat shock protein antibody levels in subjects with established hypertension.METHODS
Permanent deformations, or rutting, are internationally considered to be one of the most serious distress mechanisms in asphalt pavements. Deterioration modeling is an important tool for performance prediction and diagnostics of pavements. The Mechanistic-Empirical Pavement Design Guide (M-E PDG) model used for calculation of permanent deformation in asphalt layers was to be evaluated. It was acco
The main purpose of the present work is to increase knowledge of in-plane tension behav-iour of masonry and develop a model able to describe the impact of parameters influencing cracking caused by restrained shrinkage. In the process the mechanism of load transfer between units and mortar joints is described. The influence of cohesion between units and mortar joints, unit and joint geometry and ex
Combination chemotherapy may induce remission from acute myeloid leukemia (AML), but validated criteria for treatment of elderly are lacking. The remission intention ( RI) rate for elderly patients, as reported to the Swedish Leukemia Registry, was known to be different when comparing the six health care regions, but the consequences of different management are unknown. The Leukemia Registry, cont
Popular Abstract in Swedish Vad hade vi varit utan våra sinnen? Föreställ dig en värld utan att kunna se, höra, lukta, smaka och känna. Det är med hjälp av våra sinnen som kroppen kan känna vad som händer i vår omgivning. Ett av våra sinnen är smärtsinnet, som har till uppgift att varna oss för inre och yttre faror. Trots att smärta är den i särklass vanligaste orsaken till mänskligt lidande, så äIt is frequently argued that cannabinoids exert part of their analgesic and anti-inflammatory effects via activation of the cannabinoid CB1 receptor located on TRPV1-expressing primary sensory nerve fibres in peripheral tissues. However, we find no evidence of CB1 receptor immunoreactivity on nerve fibres in rat or mouse hindpaw skin and mesenteric artery. The CB1 receptor agonists anandamide and
To obtain a perspective of changes occurring in the marine environment it is essential to study an area over a long time span. Doing so might also facilitate the understanding of the mechanisms and processes that govern a certain marine setting. In this thesis, changes in the pelagic and benthic environment during the last c. 200 years have been investigated in two fjords on the Swedish west coast
In crossing theory for stochastic processes the distribution of quantities such as distances between level crossings, maximum height of an excursion between level crossings, amplitude and wavelength, etc., can only be written in the form of infinite-dimensional integrals, which are difficult to evaluate numerically. A Slepian model is an explicit random function representation of the process after
Phosphatidylethanol (PEth) is an abnormal phospholipid, formed only in the presence of ethanol via a transphosphatidylation reaction of phospholipase D (PLD). PEth in blood is a promising new marker of alcohol abuse. Blood PEth is found almost exclusively in red cells. This study was performed to investigate a possible PEth formation in human red cells from alcoholics and healthy individuals, at p
The max-bisection and min-bisection problems are to find a partition of the vertices of a graph into two equal size subsets that, respectively, maximizes or minimizes the number of edges with endpoints in both subsets. We design the first polynomial time approximation scheme for the max-bisection problem on arbitrary planar graphs solving a long-standing open problem. The method of solution involv
OBJECTIVE: This study aims to examine the association between various measures of adiposity and all-cause mortality in Swedish middle-aged and older men and women and, additionally, to describe the influences of age and sex on these associations. RESEARCH METHODS AND PROCEDURES: A prospective analysis was performed in a cohort of 10,902 men and 16,814 women ages 45 to 73 years who participated in
Flight directions of birds migrating at high geographic and magnetic latitudes can be used to test bird orientation by celestial or geomagnetic compass systems under polar conditions. Migration patterns of arctic shorebirds, revealed by tracking radar studies during an icebreaker expedition along the Northwest Passage in 1999, support predicted sun compass trajectories but cannot be reconciled wit
The influence of rate controlled flow reversal on the transition from planar lamellae to multilamellar vesicles (MLV) using a nonionic lamellar phase consisting of 40 wt % triethylene glycol monodecyl ether (C10E3 in D2O) is investigated by means of time-resolved rheo-small-angle light and neutron scattering (SALS, SANS). Flow reversal provides the possibility to control the kinetics of the transi
