The following presentation is primarily intended to stimulate and facilitate a future development towards an improved situation for a reliability based structural fire engineering design of timber structures. The state of the art is reviewed and a structure of a design guide or a model code is outlined. The document is written in a partially operational manner, allowing practical application for s
Background Infant or maternal injury during vaginal delivery is a constant threat to all involved, but difficult to predict. Objective To estimate the risk of birth injuries in an institution favouring trial of vaginal birth when there was doubt of the best mode of delivery. Design A retrospective cohort study. Setting University Hospital. Population Singleton 14,359 vaginal deliveries in ceph
The response of a bacterial community to liming of a forest humus soil (pH 4.9 increased to pH 7.5) was studied in the laboratory at three temperatures (5, 20, and 30degreesC). As a comparison an unlimed soil (pH 4.9) and a soil limed in the field 15 years ago (pH around 6) were also included. The bacterial community tolerance of pH was measured using TdR incorporation. The pH of the bacterial sus
Objective: to evaluate the efficacy of a micromised purified flavonoid fraction (MPFF) in the treatment of chronic venous disease (CVD). Design: prospective doable blind, randomised, control shady. Patients and methods: one hundred and one patients with symptomatic CVD were randomly allocated to treatment for 60 days with either MPFF (51 patients) or placebo (50 patients) 500 mg twice daily. There
This paper presents an analysis of the impact of childbearing history on later-life mortality for ever-married men and women using historical micro-level data of high quality for southern Sweden. The analysis uses a Cox proportional hazards model, estimating the effects on old-age mortality of number of births and timing of first and last births. By studying the effects of previous childbearing on
An image solution for the forced response of a clamped finite beam is developed. The finite beam is replaced by an infinite beam under spatially periodic excitation and periodic support reactions. The response is then found by a Fourier transform approach, making use of the periodicity. An explicit expression is found, using the Poisson sum formula. The aim is to describe the potential of using th
The kinetics and mechanism of the reaction between [PtI3(AsPh3)](-) and pyridine in acetonitrile solvent has been studied by use of stopped-flow spectrophotometry. Substitution of iodide trans to arsine is irreversible under the conditions used and takes place via parallel direct and solvolytic pathways. By comparing the rate constants of the direct pathway with literature values of the correspond
We present an investigation of current cross correlators in mesoscopic conductors. Making an analogy to the optical Hanbury Brown Twiss experiment we discuss how quantum statistical effects and two-particle interference effects can be investigated with current cross correlations. We also discuss how current cross correlations can be used for detecting two-particle entanglement and to perform quant
The conditions for binding of antibodies to glycosphingolipids separated on a thin-layer plate have been optimized for polyclonal antisera. The method has a broad detection range with low background staining. Examples are shown for the detection of blood group A and B active glycosphingolipids.
Previous studies have shown that the functional efficacy of intrastriatal transplants of fetal dopamine (DA) neurons in the rat Parkinson model depends on their ability to establish a new functional innervation of the denervated striatum. Here we report that the survival, growth, and function of the grafted DA neurons greatly depend on the severity of the lesion of the host nigrostriatal system. F
Deviations from classical two-state kinetics in protein folding need not always be explained by the presence of rapidly formed intermediates. In some cases, such deviations are caused by short-lived aggregates whereas in other cases they arise from changes of the position of the transition state. These are two new facets of the mechanism of two-state folding. The first part of this account describ
An instrument with integrated flow injection analysis (FIA) system has been developed for on-line monitoring a process for conversion of biomass under field condition. The instrument consists of a newly designed biosensor for easy renewal of the bio-receptor without disassembling the sensor, a FIA controller for controlling the analysis operations, and a computer-based data acquisition system for
Purified polyclonal immunoglobulin preparations representing the 4 rat IgG subclasses were tested for binding to Staphylococcus aureus protein A attached to 3 different solid phases (Staphylococcus aureus Cowan I bacteria, Sepharose CL4B and Sepharose 6MB). Protein A Sepharose CL4B showed higher reactivity with IgG1 and IgG2b than the staphylococci, whereas protein A Sepharose 6MB showed a lower u
