Physical activity and its effect on bone in the short- and long- term perspective.

Popular Abstract in Swedish Benskörhet (osteoporos), är ett komplext, multifaktoriellt tillstånd som utvecklas i det tysta fram till den dag man drabbas av en fraktur. De senaste 40 åren har antalet benskörhetsfrakturer ökat och i dag beräknas varannan kvinna och var fjärde man någon gång drabbas av en eller flera osteoporosrelaterade frakturer. Exempel på sådana benbrott är frakturer i kota, höftOsteoporosis is a growing problem worldwide where Sweden has one of the highest fragility fracture incidences in the world. The growing years are thought to be an opportune time to build strong bones and the enhancement of peak bone mass (PBM) has been suggested as a prevention strategy for osteoporosis. Most exercise intervention studies in children, evaluating the accrual of areal bone mineral d

Structure-activity relationships of ring C-secotaxoids. 1. Acylative modifications

The acylative modification of IDN 5390 (3a), a 7,8-secotaxoid under preclinical development, was investigated. A modest decrease of potency was observed upon acylation of the primary and the enolic hydroxyls, suggesting that, just like in paclitaxel, the hydroxyl groups in the upper right-hand sector are not critical for cytotoxicity. The activity of these analogues, and especially of the chemical

Nya gemensamma nordiska referensintervall inom klinisk kemi. Bättre bas för klinisk bedömning och samarbete

A project engaging the five Nordic countries has presented common reference intervals for the most frequently used biochemical and haematological analytes. The results are based on samples from up to 3000 healthy adult reference persons and are statistically calculated to include 95 % of the reference population’s values. Reference samples were analyzed together with commutable control materials t

BEAST decoding of block codes obtained via convolutional codes

BEAST is a bidirectional efficient algorithm for searching trees. In this correspondence, BEAST is extended to maximum-likelihood (ML) decoding of block codes obtained via convolutional codes. First it is shown by simulations that the decoding complexity of BEAST is significantly less than that of the Viterbi algorithm. Then asymptotic upper bounds on the BEAST decoding complexity for three import

Codes of Power. Deconstruction of institutional discourses

The text introduces the semiology as method in the analysis of Sociology as area of authoritarian social discourse. In opposition to an "empirical" description where the "fact" is described as if it was not "social" but a fact "of nature" the deconstruction of the Power discourse shows that the "fact" is produced as definition or description, i.e, the Power-discourse works as Code which through st

High-temperature and high-concentration SCR of NO with NH3: Application in a CCS process for removal of carbon dioxide

This study investigates several commercial selective catalytic reduction (SCR) catalysts (A–E) for application in a high-temperature (approximately 525 °C) and high-concentration (5000 ppm NO) system in combination with CO2 capture. The suggested process for removing high concentrations of NOx seems plausible and autothermal operation is possible for very high NO concentrations. A key property of

Kommunikation, medborgarskap och deltagardemokrati

Popular Abstract in Swedish Det görs en rad försök till demokratisk förnyelse ute i kommunerna. I denna avhandling är det min ambition att analysera ett sådant försök; medborgarutskotten i Helsingborg. De frågeställningar avhandlingen behandlar är 1) vad ligger bakom samtalets betoning i medborgarutskottens deltagardemokratiska aktiviteter? 2) Hur positioneras kommuninvånare som medborgare då medThis is a study of civic communication in a municipal setting. In the south Swedish municipality of Helsingborg operated Civic Committees between 2003 and 2006. The Civic Committees organized different kinds of activities together with the citizens out in the different neighbourhoods of the municipality, such as open meetings, neighbourhood walks, workshops for the future and meetings with specifi

An international consensus approach to the management of atypical hemolytic uremic syndrome in children

Atypical hemolytic uremic syndrome (aHUS) emerged during the last decade as a disease largely of complement dysregulation. This advance facilitated the development of novel, rational treatment options targeting terminal complement activation, e.g., using an anti-C5 antibody (eculizumab). We review treatment and patient management issues related to this therapeutic approach. We present consensus cl

Decay Study of 246Fm at SHIP

The decay chain of Fm-246 has been investigated employing the SHIP separator at GSI Darmstadt. The Fm-246 nuclei were produced via the Ar-40(Pb-208, 2n)Fm-246 fusion-evaporation reaction. Improved values of the half-life, T-1/2 = 1.54(4) s, and of the spontaneous fission branching ratio, b(SF) = 0.068(6), of Fm-246 were obtained. The beta(+)/electron capture branching ratio, b(EC) = 0.39(3), of Cf

Dietary Fibre Intake and Risks of Cancers of the Colon and Rectum in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Background: Earlier analyses within the EPIC study showed that dietary fibre intake was inversely associated with colorectal cancer risk, but results from some large cohort studies do not support this finding. We explored whether the association remained after longer follow-up with a near threefold increase in colorectal cancer cases, and if the association varied by gender and tumour location. Me

The strength of glulam beams with holes - A probabilistic fracture mechanics method and experimental tests

This thesis deals with experimental tests and methods for strength analysis of glulam beams with holes. Test results and methods for strength analysis available in literature are compiled and discussed. The methods considered comprise both code strength design methods and more general methods for strength analysis. New strength tests of beams with quadratic holes with rounded corners are presente

Fine-scaled orientation changes in migrating shorebirds

Flight directions and routes of migrating birds are determined by the birds' compass orientation, but also by effects of wind, social influence, responses to topography and landmarks, and to navigation cues. We investigated the orientation and routes taken by arctic shorebirds during autumn migration in southern Sweden at three different sites situated within a distance of 200 km from each other,

Macroporous gel particles as novel sorbent materials: Rational design

A novel design approach to form macroporous gels is presented. Macroporous gels (MGs), known as cryogels(or gels prepared at subzero temperatures), were prepared inside a protective plastic core (so-called, housing), thus making them resistant to shear forces at stirring. MGs are highly elastic polymeric materials with pore sizes up to 100 mu m and spongelike morphology. Design of MGs inside a pro

Analysis of factors of importance for drug use

Popular Abstract in Swedish Läkemedelsanvändning är en av sjukvårdens viktigaste behandlingsmetoder för att bota och lindra sjukdom. Samtidigt kan läkemedelsanvändning innebära risker. Det finns en risk för att patienterna får biverkningar av sina läkemedel, att läkemedlen fungerar mindre bra tillsammans och att effekten därmed upphör eller förstärks. Vidare finns det risk för att läkemedlen inte Background: There are differences in drug use depending on non-medical factors such as age, gender and socioeconomic status. The combined effect of these factors, with adjustment for multimorbidity, is highly relevant to study to ensure equality in drug use. Objectives: 1. To examine drug use related to age, gender, income and education after adjustment for multimorbidity, in an entire adult popul

Serological assessment for celiac disease in IgA deficient adults.

Selective immunoglobulin A deficiency is the most common primary immunodeficiency disorder that is strongly overrepresented among patients with celiac disease (CD). IgG antibodies against tissue transglutaminase (tTG) and deamidated gliadin peptides (DGP) serve as serological markers for CD in IgA deficient individuals, although the diagnostic value remains uncertain. The aim of this study was to

Innovation studies-The emerging structure of a new scientific field

The scholarly literature on innovation was for a long time not very voluminous. But as shown in the paper, this is now rapidly changing. New journals, professional associations and organizational units within universities focusing on innovation have also been formed. This paper explores the cognitive and organizational characteristics of this emerging field of social science and considers its pros

Assessment of aerosol optical and micro-physical features retrieved from direct and diffuse solar irradiance measurements from Skyradiometer at a high altitude station at Merak

Optical and micro-physical features of aerosol are reported using Skyradiometer (POM-01L, Prede, Japan) observations taken from a high-altitude station Merak, located in north-eastern Ladakh of the western trans-Himalayas region during January 2011 to December 2013. The observed daily mean aerosol optical depth (AOD, at 500 nm) at the site varied from 0.01 to 0.14. However, 75 % of the observed AO
