Popular Abstract in Swedish Avhandlingen omfattar tillverkning av metallmatris kompositer, MMC, baserade främst på aluminium legeringar. Nya metoder är utvecklade och undersökta där infiltrationen av fiberstrukturer av aluminiumoxid är stimulerad av mekaniska vågor vid frekvenser upp till 7 kHz. Vågrörelserna är genererade med nyutvecklad hög-magnetostriktiv aktuatorteknik. Målet med studierna harThe implementation of highly magnetostrictive wave-actuator techniques in preform infiltration processes for metal-matrix composite production is described. Metal matrix materials require additional methods to handle the content, shape and position of the ceramic reinforcements, which are not required for metal alloy casting. Commercial fabrication of advanced metal matrix composite products has

Popular Abstract in Swedish Under evolutionens gång har ett komplext system utvecklats för att hålla blodets kalkhalt konstant. Bisköldkörtelhormonet intar här en central roll. Sänkning av blodets kalkhalt ger upphov till ökad bisköldkörtelhormonsekretion. Bisköldkörtelhormonet påverkar njurar och skelett så att mer kalk återförs till blodbanan. Bisköldkörtelhormonet stimulerar också njurarna tillCalcium homeostasis after thyroid surgery was studied during the immediate postoperative period and after one year. One day after hemithyroidectomy ionised calcium decreased whereas basal PTH did not change. EDTA stimulated maximal and total PTH secretion and set-point decreased on postoperative day 1 and normalised on day 7. One year after hemithyroidectomy (n=10) total calcium and 1.25(OH)2D3 de

Lymfödem är en svullnad som kan uppkomma i olika delar av kroppen. Svullnaden uppstår på grund av att lymfvätska inte hinner dräneras bort i tillräcklig takt, utan blir kvar i vävnaden. Orsaken kan vara en medfödd genetisk svaghet i lymfsystemet alternativt en skada på lymfsystemet orsakat av operation, infektion, inflammation eller annan kroppskada. Vanligast i Sverige är lymfödem i arm eller benThe overall aim of this thesis was to develop a lymphedema-specific instrument for measuring health-related quality of life (HRQoL) and to evaluate how persons with lymphedema experience HRQoL. Lymphedema is defined as swelling in one or more parts of the body that is due to impaired lymph drainage and transport. The impairments in the lymph system can be congenital or secondary to, e.g., cancer t

In this publication we have assembled eight case studies and a ”national report” on Sweden that we wrote during 2005 as part of work commissioned by the European Foundation in Dublin. The Foundation had in the 1990’s and in the first years of the 21st  century as one of its objectives to investigate the situation for older and ageing workers in Europe, and to develop policy initiatives on the leve

This statement examines the relation of the resting ECG to its technology. Its purpose is to foster understanding of how the modern ECG is derived and displayed and to establish standards that will improve the accuracy and usefulness of the ECG in practice. Derivation of representative waveforms and measurements based on global intervals are described. Special emphasis is placed on digital signal

I kapitlet diskuteras vilka litteraturhistoriska föreställningar om arbetarlitteratur som styr dagens svenska arbetarlitteratur. Dagens varianter skildrar i stor utsträckning samhällets trasproletariat och tycks därmed ha mer gemensamt med exempelvis Maksim Gorkijs noveller från 1890-talet än med trettiotalets klassisk-kanoniska svenska arbetarskildringar. Hur kan det komma sig? Vad säger denna li

Denne korte artikkelen tar for seg preverbale adverbialer, det vil si adverbialer som kan stå mellom det initiale leddet og det finitte verbet i setninger som i ut-gangspunktet skulle ha det finitte verbet på andre plass. Disse adverbialene modifiserer den proposisjonelle kjernen i utsagnet, noe som viser seg i at når et slikt adverbial står preverbalt, kan elementer som ikke inngår i den proposi-

Fracture behavior of an ultra thin Aluminium foil was studied. For very short crack lengths, fracture has been followed in the scanner electronic microscope (SEM) with a tensile stage. A single edge notched tension specimen was used. Crack length and applied load during the crack growth were measured. These results have been used to calculate fracture strength using linear elastic fracture mechani

Inom lärarutbildningen vid Högskolan i Halmstad har handledning och examination av lärarstudenternas examensarbete nyligen förändrats. Studenterna handleds nu i grupper av handledarpar, vilka i sin tur ingår i ett lag som coachas av en kollega. Examinationen av examensarbetena har också förändrats i och med att examinatorer som är externa i förhållande till handledningen införts. Vidare har nya be

Red blood cells are are plentiful, flexible and essential. They are the most abundant cell in our body and their mainobject is to carry oxygen, which is essential for cellular respiration. The formation of red blood cells is callederythropoiesis. Erythropoiesis is intimately coupled to cell division and mitochondrial function. Aberrations in thesetwo processes are often associated with red blood c

Marfan syndrome (MFS) is a hereditary connective tissue disorder with an estimated prevalence of 1:5000–1:10 000 individuals. It is a pleiotropic disease characterized by specific ocular, cardiovascular, and skeletal features. The most common cardiovascular complication is aortic root dilatation which untreated can lead to life-threatening aortic root dissection, mainly occurring in adult patients

Cardioneuroablation has emerged as a potential alternative to cardiac pacing in selected cases with vasovagal reflex syncope, extrinsic vagally induced sinus bradycardia-arrest or atrioventricular block. The technique was first introduced decades ago, and its use has risen over the past decade. However, as with any intervention, proper patient selection and technique are a prerequisite for a safe

Abstract in Chinese 概述 学校教学最重要目的之一是赋予每个孩子同等的教育. 尽管如此, 学校再创造了社会差异. 先前的研究表明,学生的低下社会经济情况背景与自然学科成绩低下有一定联系. 这样, 不少学生在未来就被排斥在社会高端学科的教育和职业之外. 本篇论文在Bourdieu和Bernstein的理论基础上, 以自然学科课堂的社会阶级为中心, 旨在对小 学生所受的教育存在不等现象提供更多方位描述和更深层的分析. 在人种民族学的启发下, 本论文的数据取自瑞典义务小学八年级物理教室里的观察, 记录, 采访和统计调查. 1. 对教室里现象的描述和分析揭示了知识难度的下降. 这一现象的发生通常是因为自然学科的教学所具有的社会历史传统因素, 学生, 老师和教室里的谈话社交之间有无形的默契, 或被称为隐蔽的磋商, (出发点往往是善良的愿望),教室里形成了对所有学生都不利的知识难度的The overall aim of this thesis was to contribute to a more complex and multi-faceted description and analysis of inequalities in education, focusing on social class in the science classroom. Inspired by an ethnographic approach, the data was produced through observations, field notes, interviews, and a questionnaire in a Swedish compulsory school. The students aged fourteen and fifteen, were follo

Bacterial extracellular vesicles (EVs) contain numerous active substances that mediate bacterial interactions with their host and with other microbes. Best defined are the EVs from Gram-negative bacteria that have been shown to deliver virulence factors, modulate the immune responses, mediate antibiotic resistance, and also inhibit competitive microbes. Due to the complex cell wall structures of G
