Surface deterioration of concrete occurs at the waterline of many hydraulic structures in contact with soft water in cold regions. Progressive disintegration of the surface leads to exposure of the coarse aggregate and ultimately of the reinforcing steel. Mechanical, physical and chemical processes could cause deterioration of concrete at the waterline. The objective of this study was to investiga

Background A survey of the understory bryophytes in the Nectandra Cloud Forest Preserve yielded 1083 specimens distributed among 55 families, represented by 74 genera of mosses, 75 genera of liverworts and 3 of hornworts. We studied and analyzed the bryophytic distribution on six types of substrates: 1) corticolous, 2) epiphyllous, 3) saxicolous, 4) terricolous, 5) aquatic and 6) lignicolous. The

The technology shift thesisUnderstanding long term growth and transformation in a regional systemAbstractIn this paper we examines the long run economic growth and productivity performance of regions and how this relates to different phases of structural change and economic adaptability in different part of a national regional system.Firstly, we suggest a theoretical ‘systemic’ approach for analyz

The development of transparent accounting is often theoretically linked with the development of financial markets. In this paper we argue that such an understanding of transparent accounting does not necessarily consider the temporality of the historical context where transparent accounting is invented. To illustrate this argument we empirically investigate the raise of transparent accounting in S

We consider a selection of recent experimental results on electroweak W±,Z gauge boson production in pp collisions at BNL RHIC and CERN LHC energies in comparison to prediction of perturbative QCD calculations based on different sets of NLO parton distribution functions including the statistical PDF model known from fits to the DIS data. We show that the current statistical PDF parametrization (fi

Males should invest in mate attraction, mate guarding and paternal care in relation to the marginal fitness value of each of those behaviours. Since time and energy are limited, trade-offs between these activities are expected. This study demonstrates that monogamous male European starlings (Sturnus vulgaris) decrease their paternal effort in response to increased opportunities to attract addition

In this study, multi-objective optimization of the performance of a solar receiver with dimple and delta-winglet vortex generators (DWVGs) is carried out. The thermal performance and outlet dimensionless turbulent kinetic energy (TKE) are chosen as the optimization objectives. The dimple depth, dimple arrangement, the length, height, angle and spacing of the DWVGs are selected as the optimization

Introduction: The aim of the present study was to evaluate the association between serum testosterone and PSA levels in middle-aged healthy men from the general population. Materials and Methods: Based on 119 healthy men from the general population, total testosterone and PSA levels were measured. Demographic data regarding BMI, waist-to-hip ratio, smoking, and alcohol consumption were also collec

Measurements of the electroweak production of a W boson in association with two jets at high dijet invariant mass are performed using s= 7 and 8 TeV proton–proton collision data produced by the Large Hadron Collider, corresponding respectively to 4.7 and 20.2 fb- 1 of integrated luminosity collected by the ATLAS detector. The measurements are sensitive to the production of a W boson via a triple-g

The dominating form of analysis in the transport sector is cost–benefit analysis (CBA). This study investigates the purpose and use of an alternative analysis intended to complement CBA in the Swedish high-speed rail project. According to CBA calculations, the project is heavily unprofitable. While some politicians called for project termination, the project leadership launched an alternative bene

Denna avhandling har tre utgångspunkter. Den första är den europeiska sociala dialogen (ESD), vilken har kritiserats för att sakna kapacitet för att förbättra arbetsvillkor i EU. Den andra är det globala systemet för kollektivavtal och förhandlingar som har utvecklats genom ITFs kampanj mot bekvämlighetsflagg (ITF FOC), vilket anses ha kapacitet att förbättra villkor för sjömän på global nivå. DenThere are three starting points for this thesis. First, there is the system of ESD, which is criticised for lacking capacity to improve the working conditions within the EU. Secondly, there is the system developed through the global ITF FOC campaign, which is considered to have capacity to improve working conditions for seafarers at a global level. Thirdly, there is the theory on self-referential

Hypoxia-inducible factors enhance glioma stemness, and glioma stem cells have an amplified hypoxic response despite residing within a perivascular niche. Still, little is known about differential HIF regulation in stem versus bulk glioma cells. We show that the intracellular domain of stem cell marker CD44 (CD44ICD) is released at hypoxia, binds HIF-2α (but not HIF-1α), enhances HIF target gene ac

Background: This qualitative study explores former prison inmates’ perceptions and attitudes towards HIV risk inside Swedish prisons. Method: In 2014, eight semi-structured interviews were conducted with former male prisoners to gain a deeper understanding of situations perceived to be associated with risk of HIV transmission. The material gathered from the interviews was analyzed by manifest and

We studied the brittle-ductile transition in three porous carbonates, Indiana, USA, Majella, Italy, and Leitha, Austria, with porosity ranging between 16 and 31%. A series of triaxial experiments were performed at room temperature, constant strain rate, and at effective pressures ranging from 5 to 150 MPa. Several sets of X-ray Tomography images were acquired before and after deformation. 3D digit

Growth orientation is important for understanding why some young firms grow but not others, but research remains silent on the intermediary mechanisms mediating the growth orientation–firm growth relationship. We study 282 Swedish firms and show that various innovative activities mediate the growth orientation–firm growth relationship. These mediating innovative activities include informal activit

The smaller isoform of glutamic acid decarboxylase, GAD65, is an important autoantigen implicated in the pathogenesis of type 1 diabetes whereas the larger isoform, GAD67 appears to play no major role. The primary difference between the two isoforms resides in the N-terminal part of the molecule including the GAD65 membrane-anchoring domain. The aim of this study was to generate mutants of the mem

BACKGROUND: Workplace stressors, such as bullying, are strongly related to subsequent long-term sickness absence, but little is known of the possible physiological mechanisms linking workplace stressors and sickness absence. The primary aim of this study was to investigate to what extent cortisol levels were associated with subsequent sickness absence and if cortisol mediated the association betwe
