År 1960 upptäcktes Cesium-137-aktivitet från atmosfäriska kärnvapenprovvid mätningar på lågaktivitets laboratoriet iLund. Denna händelse initierade mätningar av den svenska samiska befolkningen och iprodukter från ren som betar i de svenska fjällen. En semi-bärbarhelkropps detektor konstruerades med en detektionsgräns för 137Cs som var tillräckligt bra för att mäta människor med högakroppskoncentrIn 1960 Caesium-137 activity from atmospheric nuclear weapons test was dis-covered in measurements at the whole body gamma-ray counting laboratory inLund. This event initiated measurements of the Swedish Sami population, and inproducts from reindeer that bite lichens in the Swedish mountains. A semi-portable whole-body counter designed with a detection limit for 137 Cs at high radiation background

De viktigaste orsakerna till de växande resultatskillnaderna mellan skolor och mellan elever handlar om boendesegregation och det fria skolvalet.Ökade resurser kan vara en förutsättning men inte ett tillräckligt villkor för förbättring. I den här artikeln diskuteras hur fördelningen av resurser mellan grundskolor görs och vilka erfarenheter som finns av resursfördelning i jämlikhetsskapande syfte.

Ingrid Bosseldal presenterar i den här artikeln den amerikanska psykologen Ross Greene, och reflekterar samtidigt över innebörden av de pedagogiska skillnaderna mellan att tänka "Barn gör rätt om de kan" och "Barn gör rätt om de vill" - och följderna av att välja det ena eller det andra.

Den svenska psykiatern David Eberhard hävdar att barn behöver fasta gränser, konsekvenspedagogik och att samarbetet med barnen gått för långt. I den här artikeln diskuteras dessa påståenden och prövas mot alternativa idéer om föräldra-barn-relationer.

Språkvetaren och specialpedagogen Irene Johansson utvecklade på 1970-talet en modell och ett material för språk- och talutveckling, den så kallade "Karlstadsmodellen", som därefter kommersialiserats genom produktionen av filmer, böcker, leksaker och andra artefakter, med den samlade rubriken "Babblarna". I den här artikeln presenteras några av Karlstadsmodellens grundförutsättningar: att den bygge

The magnesium status was evaluated in 30 subjects with Crohn's disease and in 30 controls. Subjects with Crohn's disease had lower concentrations of magnesium in muscle biopsy specimens (p less than 0.001), mononuclear cells (p less than 0.05), and in urine collected during 24 h (p less than 0.001) as compared with controls. After intravenous infusion of 60 mmol magnesium and 80 mmol potassium to

I den här artikeln förs en kritisk diskussion om det aktuella förslaget om att återinföra ordningsbetyg i svensk grundskola.

Zinc status was evaluated in 30 subjects with Crohn's disease. Intestinal resection had previously been performed in 23 of the subjects. The concentrations of zinc were determined in plasma, erythrocytes, percutaneous muscle biopsies, and in urine collected during 24 hours. The results were compared with those in 19 healthy controls. Most of the patients had a normal zinc status. The levels of zinZinc status was evaluated in 30 subjects with Crohn's disease.

The concentrations of magnesium, potassium and zinc were determined in plasma, erythrocytes, muscle biopsies, and in urine collected during 24 hours, in 18 subjects with type II diabetes mellitus (DM). Magnesium was also determined in mononuclear cells. The results were compared with those in 35 (magnesium and potassium analyses) or 26 (zinc analyses) healthy controls. Subjects with type II DM had

Fotografen Julia Lindemalm frågar sig i boken Zoo World vilken rätt vi har att ställa ut levande varelser. I artikeln presenteras Julia Lindemalms fotoprojekt.

Hästsporten handlar om stora pengar och nu är beskrivningen av detta på väg in i hästbokgenren. I den här artikeln diskuteras några nyutkomna hästböcker och hur de förhåller sig till sportens speciella villkor.

Navigation is the ability of animals to move through their environment in a planned manner. Different from directed but reflex-driven movements, it involves the comparison of the animal’s current heading with its intended heading (i.e., the goal direction). When the two angles don’t match, a compensatory steering movement must be initiated. This basic scenario can be described as an elementary nav

Background: Benchmarking on an international level might lead to improved outcomes at a national level. The aim of this study was to compare treatment and surgical outcome data from the Swedish National Register for Oesophageal and Gastric Cancer (NREV) and the Dutch Upper Gastrointestinal Cancer Audit (DUCA).Methods: All patients with primary oesophageal or gastric cancer who underwent a resectio

Blood flow measurements in the ascending aorta and pulmonary artery from phase-contrast magnetic resonance images require accurate time-resolved vessel segmentation over the cardiac cycle. Current semi-automatic segmentation methods often involve time consuming manual correction, relying on user experience for accurate results. The purpose of this study was to develop a semi-automatic vessel segme

Barrett's esophagus is a multistage polyclonal disease that is associated with the development of adenocarcinoma of the esophagus and esophagogastric junction. Telomerase activation is associated with cellular immortality and carcinogenesis, and increased expression of the telomerase reverse transcriptase catalytic subunit (hTERT) has been used for the early detection of malignant diseases. To ide

The aim of this study was to test the hypothesis that gastric bacterial overgrowth is a side effect of acid suppression therapy in patients with gastroesophageal reflux disease (GERD) and that the bacteria-contaminated gastric milieu is responsible for an increased amount of deconjugated bile acids. Thirty patients with GERD who were treated with 40 mg of omeprazole for at least 3 months and 10 pa

BACKGROUND: The cervical esophagus is normally lined by squamous epithelium and is usually not exposed to gastroesophageal reflux. The aims of this study were, first, to investigate whether cardiac mucosa can be acquired in the remnant cervical esophagus after esophagectomy and cervical esophagogastrostomy and, second, to characterize this mucosa if present.METHODS: The medical records of 100 pati
