A new coated time-domain reflectometry (TDR) probe design is described and evaluated. In contrast to previous coated TDR probes, our probe may be used to measure both the dielectric constant (K-a) and bulk electrical conductivity (sigma(a)) in saline porous media. This was made possible by attaching two coaxial cables to a 0.27-m three-rod with a coated central rod. The shield of the first cable w
A comparison, based on a study of how time is treated, between three development tools for real time expert system is exposed. After a presentation of the tools, some of their advantages and disadvantages arepinpointed. Since these tools are only a partial answer to the problem of real time within the expert system's area, a standpoint concerning a good use of each tool is given.
Popular Abstract in Swedish Basic Fibroblast Growth Factor (bFGF) är en av flera tillväxtfaktorer som finns lagrad i benvävnaden. bFGF framkallar celldelning och tillväxt hos många olika celltyper, däribland benceller (osteoblaster) och broskceller. bFGF kan stimulera till nybildning av blodkärl och även benvävnad. I denna avhandling undersökes om utifrån tillfört bFGF kan öka benbildning och vävnBasic Fibroblast Growth Factor (bFGF) is one of the endogenous factors found in bone matrix. bFGF is a mitogen for many cell types, including osteoblasts and chondrocytes. It can stimulate angiogenesis and osteoblast gene expression. The purpose of this study was to investigate whether exogenous bFGF can stimulate the formation of bone in bone grafts and in a bone graft substitute. All experiments
The cross section for anti-deuteron photoproduction is measured at HERA at a mean centre-of-mass energy of W-gammap=200 GeV in the range 0.2 < p(T)/M < 0.7 and y < 0.4, where M, p(T) and y are the mass, transverse momentum and rapidity of the anti-deuteron in the HERA laboratory frame, respectively. The numbers of anti-deuterons per event are found to be similar in photoproduction to those in cent
Background: The purpose of the study was to examine whether penicillin-susceptible and nonsusceptible strains of Streptococcus pneumoniae exhibited different pharmacodynamic responses to benzylpenicillin. Methods: The postantibiotic effects (PAEs) and the postantibiotic sub-MIC effects (PA SMEs) were investigated by optical density against strains of S. pneumoniae with different susceptibilities t
We investigate the effects of metallicity on the broad-band photometric colors of late-type giants, and make a comparison of synthetic colors with observed photometric properties of late-type giants over a wide range of effective temperatures (T-eff = 3500- 4800K) and gravities (log g = 0.0-2.5), at [M/H] = -1.0 and -2.0. The influence of metallicity on the synthetic photometric colors is small at
The principal aims of this thesis are to define suitable measures for safer pedestrian and cycle crossings on arterial roads, to implement these measures on a large scale and to acquire an insight into their effects on road users' safety, experiences, mobility and the environment, by creating a 30 km/h milieu at the above crossings. Two characteristically different types of measures, physical meas
The findings from the Prostate Cancer Prevention Trial (PCPT) and how they relate to the management of prostate disease were reviewed by leading European urologists during a meeting held in December 2005. The consensus opinions that were reached were endorsed by the European Association of Urology and are documented here. The key points of the consensus are as follows: (1) The overall results from
An improved ELISA method for the detection of Staphylococcal. Enterotoxin B (SEB) in protein A preparations is presented. Fab fragments were obtained by digestion with papain of anti-SEB IgG bound to SEB immobilized on Sepharose 4B. Anti-SEB and peroxidase-labeled Fab fragments from secondary antibodies were successfully used in a modified ELISA of SEB in protein A preparations. SEB-Sepharose was
Aim: To investigate the anatomical and functional results and the complications in eyes operated on using vitrectomy without scleral buckling for all forms of rhegmatogenous retinal detachment ( RRD). Methods: All cases of primary RRD at the University Hospital of Lund, Lund, Sweden, treated by one surgeon during a period of 3 years were retrospectively reviewed. In 131 ( 98%) of 134 consecutive c
Leukotriene antagonists are effective in the treatment of exercise-induced bronchoconstriction. Montelukast is a specific cysteinyl-leukotriene receptor1 antagonist without known effects on the pulmonary vessels, which in theory should be advantageous with respect to gas exchange. In addition to lung function, we investigated the effects of montelukast on parameters of gas exchange and physical pe
Using a grounded theory perspective, this article focuses on experiences of participation in relation to home among very old people who are living alone. Eight people selected from the larger ENABLE-AGE Project were interviewed. Data analysis identified the core category as "home as the locus and origin for participation" with two main categories ("performance-oriented participation" and "together
Objectives To explore case ascertainment, hospitalization, characteristics of both hospitalized and non-hospitalized patients in a population-based group of stroke patients. Materials and methods One-year screening in Lund-Orup district for first-ever strokes using multiple prospective and retrospective methods. Results A total of 456 patients with first-ever stroke (n = 412 prospective screening
A nonlinear 3D finite element model and a theoretical parameter study in relation to glued-in rods for timber structures are presented. A strain-softening crack band model was used to characterise the behaviour of the adhesive layer between the rod and the wood. The model is general in the sense that it bridges the gap between the theory of an ideal plastic bondline and the theory of linear elasti
Popular Abstract in Swedish Förekomsten av hjärt-kärlsjukdomar skiljer sig mycket mellan olika jordbruksbaserade samhällen, medan de praktiskt taget saknas helt bland samhällen som inte är baserade på jordbruk, såsom jägar- och samlarsamhällen. När man letar efter livsstilsfaktorer som skulle kunna gynna uppkomsten av kardiovaskulära sjukdomar verkar det därför logiskt att fokusera på livsstilen iThe prevalence of cardiovascular diseases (CVD) exhibits considerable variation across agrarian societies, whereas they are virtually absent in non-agrarian societies such as hunter-gatherer and horticultural societies. When looking for lifestyle factors which could promote CVD, it therefore seems logical to focus on the agrarian lifestyle and ways in which it departs from a non-agrarian lifestyle
