This paper presents a finite element analysis which is validated against laboratory tests of eight beams strengthened with externally bonded with carbon fibre reinforced plastic (CFRP) plates. The commercial numerical analysis tool Abaqus was used. Cohesive elements were used to model traction and shear behaviour of concrete/CFRP interface. The results are presented and discussed in terms of loadi

Att forska med och om ungdomar och i skolan är spännande och skrämmande. När jag forskade om ungdomar i en tysk (och sedan även i en kanadensisk) skola hade jag bestämt mig för att inte komma ut i forskningsprocessen. Vad jag inte hade väntat mig var hur det kändes att återigen befinna sig ’i garderoben’, som jag dessutom kom att reproducera. Det var å andra sidan väldigt produktivt forskningsmäss

BACKGROUND: The protective effect of physical activity (PA) on abdominal adiposity is unclear. OBJECTIVE: We examined whether PA independently predicted gains in body weight and abdominal adiposity. DESIGN: In a prospective cohort study [the EPIC (European Prospective Investigation into Cancer and Nutrition)], we followed 84,511 men and 203,987 women for 5.1 y. PA was assessed by a validated quest

Om superhjältar på film som ett svar på ett behov av föredömliga hjältar när samtiden är osäker.

Popular Abstract in Swedish Minns du din första dator? Kanske köpte familjen den på avbetalning genom jobbet för 20 000 kr och kanske kan du såhär i efterhand tycka att effektförbrukningen var lite väl hög i relation till datorns prestanda. Den gick t.ex. inte att köra på batteri. Detta är ganska långt ifrån dagens datorer, smart-TV, smarta telefoner och surfplattor där vi kan streama filmer och mThis thesis explores a novel transistor technology based on vertical InAs nanowires, which could be considered both for low-power high-frequency analog applications and for replacing Si CMOS in the continued scaling of digital electronics. The potential of this device - the vertical InAs nanowire MOSFET – lies in the combination of the outstanding transport properties of InAs and the improved elec

To study the differential expression of cell membrane-bound receptors and their potential role in growth and/or survival of the tumor cells, highly purified follicular lymphoma cells were analyzed, using gene expression analysis, and compared to non-malignant B cell populations. Filtering the genome for overexpressed genes coding for cell membrane-bound proteins/receptors resulted in a hit list of

This article reviews endovascular strategies for aortic arch repair. Open repair remains the gold standard particularly for good risk patients. Endovascular treatment potentially offers a less invasive repair. Principles, technical considerations, devices and outcomes of each technique are discussed and summarized. Hybrid repair combines less invasive revascularization options, instead of arch rep

A scanned probe optical microscope allowing nondestructive studies of a wide range of objects and surfaces is described. The microscope utilizes a noninvasive optical trap to position a microscopic probe light source in immediate proximity to the studied object. We demonstrate the method experimentally and show theoretically its potential for optical imaging with subdiffraction limited resolution
