Flowers of some Phlox (Phlox x paniculata L.) varieties undergo daily colour shifts, being blue in the early morning, turning red during the day, and returning to blue in the evening. The colour shift, which occurs only in the upper (adaxial) petal surfaces, is due to the daily changes in ambient light. In the laboratory, colour shifts could be induced by 2.5 h of ultraviolet, visible or far-red l
Aim: To estimate the incidence of dystocia, to describe outcomes of labour with dystocia and augmentation, to identify anthropometrical-, life style-, obstetric- and clinical risk indicators for dystocia, to elucidate nulliparous women’s experiences of prolonged labours and to describe some aspects of the midwifery care during labour and delivery. Design: A multi-centre cohort study with prospecti
Aims The main aim of this study was to describe the age at which pathological aortic root dilation occurs in patients with Marfan's syndrome (MFS). Methods and results A total of 160 patients with MFS attending a regional cardiac centre were reviewed retrospectively. Dilation of the ascending aorta was diagnosed by comparing the maximum aortic sinus measurement with control data from the literatur
Objective. To review the best medical management of critical limb ischaemia (CLI). Methods. Published studies dealing with CLI and risk factors were searched for via PUBMED. Findings and conclusions. Patients with critical limb ischaemia (CLI) have a one and ten year mortality of approximately 20% and 75% respectively. Risk factors for the development of peripheral atherosclerosis are the same as
The FACET (Formoterol and Corticosteroid Establishing Therapy) study established that there is a clear clinical benefit in adding formoterol to budesonide therapy in patients who have persistent symptoms of asthma despite treatment with low to moderate doses of an inhaled corticosteroid. We combined the clinical results from the FACET study with an expert survey on average resource use in connecti
The thesis treats theory and implementation aspects for stereophonic acoustic echo cancellation. In Paper I a complete implementation of a stereophonic acoustic echo canceler based on the two-channel fast recursive least-squares algorithm is presented. An analysis of the system calculation complexity is also given, in addition to simulation results on recorded real-life data. Paper II presents a
The influence of high temperature pressing on paper properties was investigated. Handsheets made of TMP, bleached and unbleached kraft pulp were pressed in a press simulator with the press surface heated to 300°C. The density, tensile strength and air permeance of the press dried sheets are compared with the values for conventionally pressed and dried reference sheets. The compression behaviour an
In order to investigate whether experimental material consisting of noise-exposed animals should be regarded as 'ears' or 'animals', a comparison was made between the permanent threshold shifts in the right and left ears in 53 groups of noise-exposed guinea-pigs, with 5 animals in each group. The action potential (N1) thresholds were measured at fourteen frequencies in both ears. In the noise-expo
In many raptors and owls the male is the main provider of food in the early phase of the nestling period while the female incubates the eggs and broods the young. In the nestling period the female often helps the male to feed the young, but the factors affecting whether and when she leaves the brood to hunt have not been investigated in detail. We present a dynamic state variable model that analys
Transgenically introduced laminin (LN) α1 chain prevents muscular dystrophy in LNα2 chain deficient mice. We now report increased integrin α7Bβ1D synthesis in dystrophic LNα2 chain deficient muscle. Yet, immunofluorescence demonstrated a reduced expression of integrin α7B subunit at the sarcolemma. Transgenic expression of LNα1 chain reconstituted integrin α7B at the sarcolemma. Expression of α- a
Phytochrome from oats (Avena sativa L. cv. Sol II), partially purified on brushite, was immobilized on Sepharose beads to which antiphytochrome immunoglobulin had been covalently linked. The immobilized phytochrome was first brought to the Pr form with unpolarized far-red light. The change in linear dichroism at 660 nm induced by plane polarized red light, and its reversal by plane polarized far-r
The BhMIR32 xyn11A gene, encoding an extracellular endoxylanase of potential interest in bio-bleaching applications, was amplified from Bacillus halodurans MIR32 genomic DNA. The protein encoded is an endo-1,4-beta-xylanase belonging to family 11 of glycosyl hydrolases. Its nucleotide sequence was analysed and the mature peptide was subcloned into pET22b(+) expression vector. The enzyme was over-e
We study the probability distribution of the height of global maximum for a Gaussian random field evolving in time. Particularly, we discuss the role of the wave kinematics. It is observed that taking into account time dynamics of spatial characteristics results in distributions different from those obtained for the static case. We show how different characteristics of the sea surface like signifi
Abstract in UndeterminedThe questions dealt with in the course of this workshop are greatly complex. In order to outline the state of the art in Southern Scandinavia the character of the archaeological and palaeobotanical source material and different theories on early agriculture are summarized. Theoretical and methodological problems implied in ecological and archaeological interpretations of th
