A Numerical Study of the Thermal Performance of Microchannel Heat Sinks with Multiple Length Bifurcation in Laminar Liquid Flow

A rectangular, straight microchannel heat sink with multiple length bifurcation has been designed, and the corresponding laminar flow and thermal performance have been investigated, numerically. Five different cases with multiple length bifurcation and various arrangements are investigated, as well as one case without bifurcations. All laminar fluid flow and surface heat transfer results are obtai

TiO2/WO3/Au nanoarchitectures' photocatalytic activity "from degradation intermediates to catalysts' structural peculiarities" Part II: Aerogel based composites - fine details by spectroscopic means

The "build-up" methodology of a composite photocatalyst is a critical issue regarding the showed photocatalytic performance, including the formation of intermediates. To investigate this issue TiO2/WO3/Au aerogel composites were obtained by sal-gel method and subsequent photoreduction (Au) with UV or visible light. The obtained composites' photocatalytic activity and intermediate formation profile

High-Frequency Gate-All-Around Vertical InAs Nanowire MOSFETs on Si Substrates

We demonstrate a vertical InAs nanowire MOSFET integrated on Si substrate with an extrinsic peak cut-off frequency of 103 GHz and a maximum oscillation frequency of 155 GHz. The transistor has a transconductance of 730 mS/mm and is based on arrays of nanowires with gate-all-around and high-kappa gate dielectric. Furthermore, small-signal modeling shows a similar to 80% reduction of the total paras

Outriggers Lost in the sea of Time: An Overlooked Aspect of Cultural Change and Conditions for Sustainable Development in Oceania

A series of comparative studies is suggested, focused on perceptions of outrigger canoes, and aimed at an increased understanding of the relationship between social relations, biodiversity, and sustainable development in Oceanic societies on small islands and in coastal areas undergoing rapid cultural change. After a critique of the recent notion that canoe-building in Polynesia developed as a res

Emerging role of SOX11 in mantle cell lymphoma

During recent years the neural transcription factor SOX11 has been established as an important biomarker for mantle cell lymphoma. SOX11 is both a diagnostic and prognostic antigen, and may potentially be used for treatment selection for younger patients, in relation to protocols including high dose chemotherapy. The molecular pathways involved are still not fully elucidated and, as SOX11 can inte

Cultural Dissimilarity and Intermarriage. A Longitudinal Study of Immigrants in Sweden 1990-2005

Intermarriage with natives is a key indicator of immigrant integration. This article studies intermarriage for 138 immigrant groups in Sweden, using longitudinal individual level data. It shows great variation in marriage patterns across immigrant populations, ranging from over 70 percent endogamy in some immigrants groups to below 5 percent in other groups. Although part of this variation is expl

PCBaSe Sweden: A register-based resource for prostate cancer research

Objective. To construct a database for clinical epidemiological prostate cancer research based on linkages between the National Prostate Cancer Register (NPCR) of Sweden, a population-based, nationwide quality database, and other nationwide registries. Material and methods. By use of the individually unique Swedish Personal Identity Number, the NPCR was linked to the Swedish Cancer Registry, the C

Suppression of charged particle production at large transverse momentum in central Pb-Pb collisions at root s(NN)=2.76 TeV

Inclusive transverse momentum spectra of primary charged particles in Pb-Pb collisions at root s(NN) = 2.76 TeV have been measured by the ALICE Collaboration at the LHC. The data are presented for central and peripheral collisions, corresponding to 0-5% and 70-80% of the hadronic Pb-Pb cross section. The measured charged particle spectra in |eta| < 0.8 and 0.3 < p(T) < 20 GeV/c are compared to the

Sequential Monte Carlo Methods with Applications to Positioning and Tracking in Wireless Networks

This thesis is based on 5 papers exploring the filtering problem in non-linear non-Gaussian state-space models together with applications of Sequential Monte Carlo (also called particle filtering) methods to the positioning in wireless networks. The aim of the first paper is to study the performance of particle filtering techniques in mobile positioning using signal strength measurements. Two di

Auditory event-related potentials and cognitive outcome after very preterm birth

Popular Abstract in Swedish Barn födda före 32 gestationsveckor, även de utan svåra neurologiska avvikelser, har en hög förekomst av neuropsykologiska problem såsom läs-, inlärnings-, språk-, minnes- och beteendeproblem. Det är ännu inte klarlagt vilka funktionella och strukturella förändringar i hjärnan som orsakar dessa problem. Möjligheten till tidig diagnos behövs men saknas ännu. Auditiva hänChildren born before 32 gestational weeks have a high incidence of neuropsychological deficits. The structural and functional correlates of such impairments in preterm infants are incompletely understood, and early diagnostic tools are needed, but still lacking. Auditory event-related potentials (AERPs) are neurophysiological measures of cortical sound detection, encoding, discrimination, and atte

Lavar på den skotska västkusten

I samband med årets internationella mykologikongress IMC9 i Edinburgh anordnade IAL, International Association for Lichenology, en veckas lavexkursion på den skotska västkusten under ledning av Chris Ellis och Brian Coppins, den senare en av världens främsta lavexperter. Martin Westberg och Ulf Arup var med och skådade oceaniska rariteter.

A novel blood-based biomarker for detection of autism spectrum disorders.

Autism spectrum disorders (ASD) are classified as neurological developmental disorders. Several studies have been carried out to find a candidate biomarker linked to the development of these disorders, but up to date no reliable biomarker is available. Mass spectrometry techniques have been used for protein profiling of blood plasma of children with such disorders in order to identify proteins/pep

Genetic Polymorphisms in Host Innate Immune Sensor Genes and the Risk of Nasopharyngeal Carcinoma in North Africa

Nasopharyngeal carcinoma (NPC) is a rare malignancy in most parts of the world. It is an Epstein-Barr virus-associated malignancy with an unusual racial and geographical distribution. The host innate immune sensor genes play an important role in infection recognition and immune response against viruses. Therefore, we examined the association between polymorphisms in genes within a group of pattern

Health-promoting educational interventions: A one-year follow-up study

Aims: The purpose of this study was to describe and analyse the effects of health-promoting educational interventions among employees in a municipality in Sweden. Methods: A randomized controlled educational intervention study was performed with 340 employees. Supervisors and workplace champions took part in two separate educational programmes with focus on health promotion. Intervention groups we

Patient-Specific Whole-Body Attenuation Correction Maps from a CT System for Conjugate-View-Based Activity Quantification: Method Development and Evaluation.

Abstract For activity quantification based on planar scintillation camera measurements, photon attenuation is an important factor that needs to be corrected for in a patient- and organ-specific manner. One possibility for obtaining attenuation correction maps is to use X-ray CT scout images. Since the intensity of scout images is in relative numbers, their image values need to be multiplied by a f

Genomic characterization of ETV6/RUNX1-positive acute lymphoblastic leukemia

The t(12;21) translocation generates the ETV6/RUNX1 fusion gene, present in 25% of childhood acute lymphoblastic leukemia. This fusion gene is important for leukemia development but is not sufficient for leukemia to arise. Hence, the additional genetic changes present in leukemic ETV6/RUNX1-positive cells give important clues regarding the history of the leukemia. The aim of this thesis has been t
