It has been suggested that a parent–teacher–student conference should centre on the capacities and good qualities of the student. This article focuses on teacher discourse in situations where the students’ answers (in mathematics tests, written assignments etc.) are either entirely or almost entirely correct. The study shows that, in eight cases out of ten, the comments made reflect a “deficiency

The effect of pulsed electric field (PEF) pretreatment on solid-liquid expression from potato tissue was studied on individual parenchyma tissue samples for different PEF intensities, varying relative deformations and deformation rates. The yield increased with relative deformation. The yield at any given relative deformation increased with increased PEF intensity and decreased deformation rates.

Popular Abstract in Swedish Flertal studier talar för att såväl vaskulär demens som demens av Alzheimers typ är relaterade till blodtrycksnivå tidigare under livet. En studie har visat att redan blodtrycket vid 50- årsåldern är relaterat till kognitiva (intellektuella) funktioner vid 70-års ålder. En annan studie har visat att hypertoni i 70-årsåldern föregår utveckling av demens i ålder 80-85 år."Men born 1914" is a population based cohort study of the epidemiology of cardiovascular disease. Five hundred men, born 1914, were examined at the age of 68 and 185 of them were re-examined at 81 years of age. Examination included a medical and a psychological investigation, ultrasonographic measurement of carotid arteries, 24-hour ambulatory blood pressure monitoring, regional cerebral blood flo

Diffractive interactions represent a lively domain of investigations, as confirmed by the progresses reported during the conference. We summarize the diffractive interactions session and put the new experimental data (Section 1), developments in modeling diffraction (Section 2) and the theoretical relations with Quantum Chromodynamics (Section 3) in perspective.

Background: Infection with group B streptococci (GBS) is a serious neonatal disease. The GBS cell surface proteins a and Rib elicit protective immunity in animal models and have been suggested as potential antigens in a vaccine against human GBS disease. Aims: To test the hypothesis that transplacentally transferred maternal antibodies to GBS proteins contribute to the protection of the neonate fr

Popular Abstract in Swedish Denna avhandling handlar om kvinnor och ekonomisk förändring i Sverige under 1900-talet. Den centrala frågeställningen är hur kvinnors förändrade utbildning och arbetsmarknadsdeltagande har påverkat och samvarierat med fertilitet över tid. Även om många idag anser Sverige vara ett jämställt land där män och kvinnor har lika möjligheter, fortsätter traditionella könsrollThis book deals with women and socioeconomic change in twentieth century Sweden. The main focus is on how women’s education and labor force participation have affected fertility over time. Although many perceive Sweden as a country where men and women have equal opportunities, traditional gender roles continue to constrain male and female activities and opportunities. The gender division of labor

Popular Abstract in Swedish Skador på kotor i bröst- eller ländryggen efter en olycka kan omfatta allt ifrån en diskret skelettskada till en kotfraktur kombinerad med skador på diskar (mellankotskivor), leder, ligament, mjukdelar, nervrötter och (eller) ryggmärg. En kotfraktur kan därför leda till allt från lättare övergående besvär till kronisk smärta och invaliditet. Även patientens ålder, kön oFrom the radiographic archives at the Malmö University Hospital, Malmö, Sweden, we identified children below age 16 years (n=74) and adolescents between 16 to 18 years (n=40) with a clinically and radiographically diagnosed thoracic or lumbar vertebral fracture between 1950 to 1971 (with exception of two years of missing radiographs), and all adults above age 18 years (n=39) with a non-operatively

Hypothesis: En bloc esophagectomy (EBE) provides improved survival over transhiatal esophagectomy (THE) in patients with similarly sized transmural tumors (T3) and lymph node metastases (N1). Design: A retrospective case-control study of 2 methods of esophageal resection for cancer. Setting: University hospital (tertiary referral center for esophageal disease). Patients: There were 49 patients (27

We study the influence of the major compensating defects As antisites and Mn interstitials known to occur in the GaMnAs ferromagnetic semiconductor on its structural properties. Our experimental results show that there is a balance between Mn interstitial and As antisite defects, leading to the reduced density of one type of defect upon increasing the density of the other defect. Significant diffe

Popular Abstract in Swedish Förbränning är den viktigaste energikällan på jorden och en ökad förståelse av förbränningsprocesser är väsentlig för att minska miljöfarliga utsläpp och för att öka effektiviteten av förbränningsanläggningar och motorer. För detta ändamål är det viktigt att bestämma bl. a. koncentrationer av ämnen som bildas under förbränningen. Laserbaserade mätmetoder möjliggör berörCombustion is the most important source of energy worldwide. A better understanding of it is essential if pollutant emissions are to be reduced and combustion devices be made more efficient. This requires measurement of physical and chemical combustion parameters. Laser-induced fluorescence (LIF) is widely employed as a laser-diagnostic technique for the detection of combustion species but it suff

This article outlines experimental laboratory and field studies on creep of young or mature High Performance Concrete, HPC, carried out between 1991 and 1999. For this purpose about 400 cylinders made out of 8 mix compositions of HPC were studied in the laboratory. Half the number of HPC was sealed; half of the studies were carried out on air-cured HPC. Parallel tests on strength, internal relativ

The displacement method developed for the analysis of the stability of circular arches in paper (1) excludes the mass of the arch. To overcome the shortcomings of paper (1) in this respect, the method of initial parameters is employed below in the derivation of the frequency equations of a circular arch subjected to a nonconservative follower force Q at the free end (Figs 1, 2) and taking into acc
