Ännu en skånsk höstmorgon. Om framtiden är nu, så är den vacker. Inga större problem att vakna. Problemet är väl snarare att stiga upp. Ryggen är som vanligt lite stel. Tänk att jag varit pensionär i ett halvår. Många tyckte jag gick tidigt som 73-åring. Själv hade jag hela tiden haft 2040 som en gräns. Nu blev det ett år tidigare. Skönt. Som vanligt på morgonkvisten far tankarna fritt, många snur

Two dinuclear manganese complexes, [Mn2BPMP(@m-OAc)2].ClO4 (1, where BPMP is the anion of 2,6-bis{[N,N-di(2-pyridinemethyl)amino]methyl}-4-methylphenol) and [Mn2L(@m-OAc)2].ClO4 (2, where L is the trianion of 2,6-bis{[N-(2-hydroxy-3,5-di-tert-butylbenzyl)-N-(2-pyridinemethyl)amino]met hyl}-4-methylphenol), undergo several oxidations by laser flash photolysis, using rutheniumII-tris-bipyridine (tri

Nonlinear discrete-time modeling of a Web server system is investigated. Server systems typically contain nonlinearities such as saturations and bounded queue lengths. The incoming traffic and service rates are best modeled by stochastic processes, well described and analyzed by queuing theory. Here, we develop and validate a control theoretic model of a general single server queue, a so-called G/

Romania has for a long time been lacking good palaeoenvironmental records, particularly for the Late Quaternary. A chronological framework had been nearly absent and the vegetation development had been reconstructed entirely from pollen data. Data sets from this part of Europe are important for assessing the spatial variability of past vegetation and climatic changes and to reconstruct tree migrat

In this report we present an extension of the pooled analysis of the prognostic impact of urokinase-type plasminogen activator (uPA) and its inhibitor PAI-I in breast cancer patients. We analyzed a different endpoint, metastasis-free survival (MFS). We checked the consistency of the estimates for uPA and PAI-I for relapse-free survival (RFS) and MFS exploring possible sources of heterogeneity. Nod

Popular Abstract in Swedish De flesta samhällsvetarna har betrakat de fattiga i utvecklingsländerna as marginella perse: de saknar de psykologiska förutsättningarna för att handla rationellt. Med min avhandling vill jag argumentera mot detta perspektiv. Jag göt det genom att bevisa att deras handlingar är rationella; de måste ta itu med ekonomiska, sociala, politiska och kulturella hinder som härmIn the present doctoral dissertation an attempt is made to qualify the theorertical assumptions about the marginal characret of the popular sectors of the developing countries. According to these theories, individuals belonging to the populart sectors cannot become fully members of their societies because they lack the attitudinal prerequisites. My argument is that their actions are quite sophisti

An assessment of impacts on Arctic terrestrial ecosystems has emphasized geographical variability in responses of species and ecosystems to environmental change. This variability is usually associated with north-south gradients in climate, biodiversity, vegetation zones, and ecosystem structure and function. It is clear, however, that significant east-west variability in environment, ecosystem str

An attempt to modify perception and evaluation of student teachers with the aid of self-confrontation mediated with video recordings on one hand and conventional tutoring on the other is the subject of this report. Background to the experiment, a detailed description of the layout and a presentation of the measuring instruments are given together with evaluation of the internal and external validi

Boken är utgiven med anledning av Lars-Erik Nevanders 70-årsdag och baseras på ett symposium i Lund 1991 med föredrag av personer som arbetat med Nevander under hans tid som professor i Lund. Föredragen hölls av en bred samling internationella namn och omfattar ett brett spektrum bl a klimat & fuktfrågor, betong- och murverkskonstruktioner m.m.This book is dedicated to Lars Erik Nevander, who turned 70 in the autumn of 1991. An international symposium was held in Lund in September of 1991 to which participants were specially invited who had worked with Lars Erik Nevander in one connection or another during the time of his professorship at Lund University. Invited papers presented by some 20 of the participants illurninated important d

Eight patients with colloid cysts of the third ventricle were examined with CT and MR. In six, surgical resection was performed and the material was subjected to histologic evaluation; the concentrations of trace elements were determined by particle-induced X-ray emission. Stereotaxic aspiration was performed in two. The investigation showed that colloid cysts are often iso- or hypodense relative

A novel gene was identified 52 kb upstream of the gene encoding the protease inhibitor elafin (PI3) on human chromosome 20q12-13.1. The transcript of the new gene, denoted huWAP2, was characterized by rapid amplification of cDNA ends and DNA sequencing. The size is 774 bp and it gives rise to a polypeptide of 111 amino acid residues that is homologous to elafin and similar WAP-type protease inhibi

DELPHI results are presented on the inclusive production of two (K(K) over bar π)(0) states in the mass region 1.2-1.6 GeV/c(2) in hadronic Z decays at LEP I. The measured masses (widths) are 1274 +/- 6 MeV/c(2) (29 +/- 12 MeV/c(2)) and 1426 +/- 6 MeV/c(2) (51 +/- 14 MeV/c(2)), respectively. A partial-wave analysis of the (K(K) over bar π)(0) system shows that the first peak is consistent with the

Cell surface proteins of the human gastric pathogen Helicobacter pylori, reference strain CCUG 17874, were extracted with acid glycine and fractionated by heparin affinity chromatography. The extracts were subsequently analysed using high-resolution two-dimensional gel electrophoresis (2-DE) and immunoblotting. Four proteins of low molecular masses (25-30 kDa) stained by Coomassie R-350, were iden

Popular Abstract in Swedish I blodet finns röda och vita blodkroppar eller blodceller, som är nödvändiga för vår överlevnad. Blodcellerna utvecklas i benmärgen från gemensamma ursprungsceller, så kallade stamceller och en konstant nyproduktion pågår genom hela livet. Under produktionen av mogna celler tillväxer och delar sig cellerna och får allt mer specialiserade egenskaper. Denna specialiseringAll hematopoietic cells are derived from the hematopoietic stem cells (HSCs) in a continuous and dynamic process, regulated by a network of transcription factors in different combinations and extrinsic signals from growth factors (GFs) and other factors in the microenvironment. In the initial stages of hematopoiesis HSCs differentiate to progenitor cells with gradually more restricted lineage pote

Methods. Among 985 Olmsted County, Minnesota, residents who experienced an osteoporotic fracture (distal forearm, humerus, clavicle/scapula/sternum, ribs, vertebrae, pelvis, hip, other femur or tibia/fibula [the latter in women only]), we estimated the incremental cost of direct medical care in the following year compared with age- and sex-matched controls without a fracture randomly sampled from
