Flow-pattern based heat transfer correlations for stable flow boiling in micro/minichannels

Flow-pattern based heat transfer correlations for elongated bubbly flow and annular flow in stable flow boiling micro/minichannels were developed separately based on a collected micro/minichannel heat-transfer database by using an improved conventional-to-micro/minichannel threshold Bo = 4 and BoRel0.5 = 200, where Bo is the Bond number and Rel is the liquid Reynolds number. As significant disagre

Om betydelsen av böckers utseende : det svenska förlagsbandets framväxt och etablering under perioden 1840–1914 med särskild hänsyn till dekorerade klotband : en studie av bokbandens formgivning, teknik och relation till frågor om modernitet och materiell kultur.

This study traces the history of publishers’ cloth-bindings in Sweden, and places them in relation to the emergence of modernity. The interaction between techno-logy, economics and aesthetics is central to the analysis, in which a sociological approach is combined with per-spectives of book history and material culture studies. • The study consists of two parts: Book culture in transit-ion, mainly

Moisture safety in wood frame walls : blind evaluation of the hygrothermal calculation tool WUFI 5.0 using field measurements and determination of factors affecting the moisture safety

Due to increased awareness of climate change and higher energy costs, well‐insulated buildings have become more common. Furthermore, the interests of using wood in building to produce more carbon dioxide‐efficient houses have increased. However, thicker thermal insulation in walls increases the risk of high relative humidity levels and the risk of mould‐related damage in Wood frame houses. In orde

Is the association between physical activity and healthcare utilization affected by self-rated health and socio-economic factors?

Physical activity and healthcare utilization has negative association. However, there appears to be limited knowledge of how this association is affected by self-rated health (SRH) and socio-economic status (SES). Therefore, the aim of this study was to examine the association between leisure-time physical activity (LTPA) and healthcare utilization, and investigate how SRH, gender, age and SES aff

Size-structured risk assessments govern Daphnia migration.

One of the more fascinating phenomena in nature is animal mass migrations and in oceans and freshwaters, diel variations in depth distribution of zooplankton are a phenomenon that has intrigued scientists for more than a century. In our study, we show that zooplankton are able to assess the threat level of ultraviolet radiation and adjust their depth distribution to this level at a very fine tuned

Glaucoma Diagnostics

Popular Abstract in Swedish Bakgrund Den kroniska ögonsjukdomen grön starr (glaukom) skadar ögats synnerv och påverkar den perifera synen (synfältet) hos de som drabbas. I västvärlden är grön starr den näst vanligaste orsaken till blindhet enligt Världshälsoorganisationen WHO. I Sverige räknar man med att cirka 70 000 personer över 70 år har grön starr, men att endast hälften av dessa är kända förThis thesis addresses several aspects of glaucoma diagnostics from both a clinical and a screening perspective. New instruments for diagnosing glaucoma have been developed over the past years, but little information is available regarding their performance as screening methods and their usefulness in ordinary clinical practice. Purpose of the research underlying this thesis The objectives of the

Composition and structure of mixed phospholipid supported bilayers formed by POPC and DPPC

In this paper we present a systematic study of the morphology and composition of supported lipid bilayers (SLBs) formed by vesicle fusion using a wide variety of surface sensitive techniques that give information about the lateral as well as vertical structure and bilayer fluidity. SLBs of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC

Model-Based Optimization of Tapered Free-Electron Lasers

The energy extraction efficiency is a figure of merit for a free-electron laser (FEL). It can be enhanced by the technique of undulator tapering, which enables the sustained growth of radiation power beyond the initial saturation point. In the development of a single-pass x-ray FEL, it is important to exploit the full potential of this technique and optimize the taper profile aw(z). Our approach t

Danska spår i syd- och västsvenskt kyrkoliv - kan LUKA ge svar?

Traces of Danish-Norwegian Church life in South and Western Sweden did not disappear after 1658. Rather the nineteenth and twentieth century changes of Church structure and services weakened or dispersed of the Danish traces. But then they were not any more interpreted as Danish. The ongoing, frequent amalgamation of parishes means a final break with the original, Danish Church structure in the co

Charged pion identification at high p. T in ALICE using the TPC dE/dx

The ALICE TPC provides excellent charged particle tracking to study pp and Pb-Pb collisions at LHC. The TPC allows also particle identification (PID) via the measurement of the specific ionisation dE/dx. At high p(T) (p(T) > 3 GeV/c) this is accomplished in the region of the relativistic rise of the energy loss, and provides a measurement of the yields of charged pions, kaons; and protons. Here, w

Distribution of CGRP and CGRP receptor in the trigeminovascular system and CNS

Calcitonin gene-related peptide (CGRP) has a key role in the pathophysiology of migraine and is associated with activation of the trigeminovascular system. Recently, CGRP receptor antagonists have been developed with clinical efficacy. The present thesis aimed therefore to investigate the distribution of CGRP and the CGRP receptor in the trigeminovascular system and in parts of the CNS. In the tri

PIXE-electrophoresis shows starving collembolan reallocates protein-bound metals.

One of multiple functions of metalloproteins is to provide detoxification to excess metal levels in organisms. Here we address the induction and persistence of a range of low to high molecular weight copper- and zinc binding proteins in the collembolan species Tetrodontophora bielanensis exposed to copper- and zinc-enriched food, followed by a period of recovery from metal exposure, in absence and

Improved Interpretation of Myocardial Perfusion Images by Artificial Neural Networks

Popular Abstract in Swedish Tolkning av medicinska bilder kan vara svår och påverkar i hög grad det fortsatta handläggandet av patienten. De viktigaste förutsättningarna för ett bra tolkningsresultat är förutom läkarens erfarenhet, som byggs upp genom att tolka många bilder, även kvaliteten på bilderna. Under det senaste decenniet har bilddiagnostiken utvecklats snabbt. Digitaliseringen av bilden Correct interpretation of medical imaging is based upon the interpreter’s experience and image quality. Depending on the report given the clinician decides how to use the result of the study. For many years a large number of image technologies including myocardial perfusion scintigraphy (MPS) have been acquired in digital format and the development of the imaging modalities are progressing rapidly

Ultrasound features of human carotid plaques

Popular Abstract in Swedish Ultraljud kan avslöja farliga plack Stroke orsakas ofta av att en blodpropp, som utvecklats i de områden av blodkärlen som drabbats av åderförkalkning, täpper till ett blodkärl som försörjer hjärnan med blod. Genom att med ultraljud studera de plack som utgör åderförkalkningen, kan man få ytterligare information för att bedöma en individs risk att drabbas av stroke. HjäAtherosclerotic plaques in the carotid arteries are common in a middle-aged population. When a carotid plaque ruptures it may result in a cerebrovascular event. However, only a minor part of carotid plaques will eventually rupture. Finding those plaques is essential to decide the most appropriate treatment strategy. With non-invasive ultrasound the carotid plaques can be visualized for assessment

Critical parameters in blood processing for T-cell assays: Validation on ELISpot and tetramer platforms

Assays detecting antigen (Ag)-specific T-cell responses in immune-mediated processes are increasingly employed to understand disease pathogenesis and "immune staging". The quantity and quality of starting peripheral blood mononuclear cell (PBMC) preparations are important factors in the performance of such assays. We therefore compared final PBMC yield and function by modifying parameters at the b

Impact of the ion-ion energy transfer on quantum computing schemes in rare-earth doped solids

We analyze the Ce3+-Pr3+:Y2SiO5 emission spectra obtained under selective excitation of the two Ce3+ sites in Y2SiO5 and we show clear evidence of direct energy transfer from Ce3+ to Pr3+. Energy transfer microparameters were calculated from the experimental spectral overlap between the Ce3+ emission and the Pr3+ and Eu3+ absorptions from which, the transfer mechanisms Ce3+-> Pr3+ are concluded to
