Six years ago we reported the discovery of a central place at Uppakra in southern Sweden which promised to be unusually rich and informative (Hardh 2000). At 40ha it already stood out as the largest concentration of residual phosphate in the whole province of Scania, with surface finds of Roman and late Iron Age metalwork (second-tenth century AD). Following this thorough evaluation, the project m
The blood group ABO gene codes for a glycosyltransferase that adds the ultimate monosaccharide to a glycoconjugate and forms the A or B blood group specific antigen. The DNA structure of the three major alleles of the human blood group ABO system was first described in 1990. This review describes the subsequent developments, including the increasing number of variants of these common alleles and t
Context. The stellar abundance ratio of Mg/Fe is an important tool in diagnostics of galaxy evolution. In order to make reliable measurements of the Mg abundance of stars, it is necessary to have accurate values for the oscillator strength (f- value) of each of the observable transitions. In metal-poor stars the MgI 3p-4s triplet around 5175 angstrom (Fraunhofer's so-called b lines) are the most p
Popular Abstract in Swedish Ojämnheter i vägen orsakar påkänningar i åkande fordon. För fordonstillverkare är det intressant att veta egenskaperna hos dessa vägojämnheter. Det är lämpligt att använda statistiska metoder för att analysera mätningar av vägytor/vägprofiler, dels eftersom mätningarna ger stora mängder data och dels eftersom vägytor har ett slumpmässigt beteende (från en 100 meter långRoad profiles are studied from a vehicle fatigue point of view. A wide range of roads have been measured: from smooth motorways to very rough gravel roads. It is observed that the road profiles consist of irregular sections, which makes the stationary Gaussian model unsuitable (Paper A). In Paper B, a method for automatic identification of such irregularities is presented. It is verified that the
Background: Transcription factors are frequently involved in the process of cellular transformation, and many malignancies are characterized by a distinct genetic event affecting a specific transcription factor. This probably reflects a tissue specific ability of transcription factors to contribute to the generation of cancer but very little is known about the precise mechanisms that governs these
Object: The abdominal aorta (AA) has a predilection for aneurysm formation. An etiologic factor may be underlying aortic wall stress. The purpose of this study was to examine whether the intima-media thickness (IMT) of the AA, as a surrogate to arterial wall thickness, can be measured noninvasively with satisfactory results to calculate circumferential wall stress, and to evaluate regional and gen
In this paper, we study convergence of truncated representations of the frequency-response operator of a linear time-periodic system. The frequency-response operator is frequently called the harmonic transfer function. We introduce the concepts of input, output, and skew roll-off. These concepts are related to the decay rates of elements in the harmonic transfer function. A system with high input
A biosensor for monitoring acetonitrile was constructed. A mixed culture was taken from a degradation reactor and mounted on top of a Clark electrode. The amperometric biosensor was placed in a flow-through cell and integrated into a flow injection system. The metabolic response in terms of oxygen consumption was well correlated to the concentration of acetonitrile in standard solutions. However,
We address ideas and talk about leadership in a research and development (R&D) company. The meaning that middle and senior managers ascribe to leadership is explored. We show how initial claims about leadership values and style tend to break down when managers are asked to expand on how they perceive their leadership and account for what they actually do in this respect. We raise strong doubts

We use a train of sub-200 attosecond extreme ultraviolet (XUV) pulses with energies just above the ionization threshold in argon to create a train of temporally localized electron wave packets. We study the energy transfer from a strong infrared (IR) laser field to the ionized electrons as a function of the delay between the XUV and IR fields. When the wave packets are born at the zero crossings o
Literary scholars have taken very little interest in the first collection of fables published in Swedish, Hundrade Esopi Fabler (A Hundred Fables of Aesop, 1603), compared to the interest shown its European counterparts. Based on research in the interdisciplinary field of ecclesiastical history, the present paper relates Hundrade Esopi Fabler to the concept of confessionalization, elaborated in re
Molecularly imprinted micro- and nano-particles can be conveniently prepd. using pptn. polymn. method. By controlling the initial reaction compn., the resulting polymer particles may be obtained as uniform beads that display favorable binding characteristics. Incorporation of a novel reporter element resulted in an imprinted scintillation polymer that displayed an enhanced signaling
