Does size matter? Attendance numbers at SI-sessions and how it affects learning conditions

Supplemental Instruction (SI) is today a well-known academic support model to address retention and student performance in higher education. However, in studies reporting the effect of SI, the number of attendees at SI-sessions are seldom mentioned or reflected upon.This study investigates if there is a lower, optimal, and upper number of SI-attendees for SI-sessions with viable learning condition

Pool Boiling on Structured Surfaces: Heat Transfer and Critical Heat Flux : Experiments and Mechanistic Modelling

In this thesis, pool boiling heat transfer was experimentally studied on structured surfaces with dielectric liquids (HFE-7200, NOVEC-649, FC-72), organic liquids (Acetone, Pentane) and deionized water.In the first step, nanoparticle coatings on copper surfaces were prepared by an electrophoretic deposition method, with Cu-Zn nanoparticles (100 nm) and Cu nanoparticles (150 nm). Two types of nanop

Thermo-Viscoplasticity for Case Hardening Steels at Finite Deformations and Wide Temperature Ranges

The aim of this work is the development of a thermodynamically consistent fully coupled thermo-viscoplastic material model for metals undergoing finite deformation and large temperature changes.The deformation gradient is supposed to be decomposable into a thermal, an elastic, and a plastic part, where purely volumetric thermal expansion and isochoric plastic distortion is assumed. The model is ba

A case of acute interstitial nephritis caused by sodium valproate is reported. The sodium valproate treatment was continued after initial diagnosis and the patient developed end-stage renal failure. After transplantation, interstitial nephritis was demonstrated in the renal graft.

Using rainfall-runoff modeling to interpret lake level data

Using water balance computations, the behavior of different kinds of lakes is discussed. Simple analytical expressions relating water level to hydrological conditions and lake bathymetry are given. The importance of knowing the river basin area when analyzing lake levels is stressed. A conceptual rainfall-runoff model including lake routing is used to simulate runoff and lake levels and to compute

A Bacterial Effector Mimics a Host HSP90 Client to Undermine Immunity

The molecular chaperone HSP90 facilitates the folding of several client proteins, including innate immune receptors and protein kinases. HSP90 is an essential component of plant and animal immunity, yet pathogenic strategies that directly target the chaperone have not been described. Here, we identify the HopBF1 family of bacterial effectors as eukaryotic-specific HSP90 protein kinases. HopBF1 ado

The Political Dynamics of Portfolio Design in European Democracies

The design of government portfolios - that is, the distribution of competencies among government ministries and office holders - has been largely ignored in the study of executive and coalition politics. This article argues that portfolio design is a substantively and theoretically relevant phenomenon that has major implications for the study of institutional design and coalition politics. The aut

Early Vascular Aging in the Young : Influence of Birth Weight and Prematurity

Longitudinal data from cohort studies show that early life factors such as low birth weight are associated with the development of hypertension, coronary heart disease, and type 2 diabetes in adulthood. Moreover, the majority of published studies concur that blood pressure is higher in adolescents and young adults with a history of low birth weight. Although the precise mechanisms linking early li

Efficacy of Lactobacillus rhamnosus GG in treatment of acute pediatric diarrhea : A systematic review with meta-analysis

BACKGROUND Diarrhea is a major infectious cause of childhood morbidity and mortality worldwide. In clinical trials, Lactobacillus rhamnosus GG ATCC 53013 (LGG) has been used to treat diarrhea. However, recent randomized controlled trials (RCTs) found no evidence of a beneficial effect of LGG treatment. AIM To evaluate the efficacy of LGG in treating acute diarrhea in children. METHODS The EMBASE,

Efficient Solution-Phase Parallel Synthesis of 4-Substituted N-Protected Piperidines

Practical conditions for the synthesis of 4-substituted N-protected piperidines through CuCN·2LiBr-catalyzed organozinc additions to 1-acylpyridinium salts and subsequent hydrogen-transfer hydrogenation have been established. The reaction sequence is performed at room temperature and provides 4-substituted N-protected piperidines in excellent overall yields without the isolation of intermediate di

Discovery of potent and selective small-molecule PAR-2 agonists

Proteinase activated receptor-2 plays a crucial role in a wide variety of conditions with a strong inflammatory component. We present the discovery and characterization of two structurally different, potent, selective, and metabolically stable small-molecule PAR-2 agonists. These ligands may be useful as pharmacological tools for elucidating the complex physiological role of the PAR-2 receptors as

Caregiving time costs and trade-offs: Gender differences in Sweden, the UK, and Canada

Population ageing is putting pressure on pension systems and health care services, creating an imperative to extend working lives. At the same time, policy makers throughout Europe and North America emphasize home care. Thus, the number of people combining caregiving responsibilities with paid work is growing. We investigate the conflicts that arise from this by exploring the time costs of unpaid

Effect of hydrogen chloride etching on carrier recombination processes of indium phosphide nanowires

Introduction of in situ HCl etching to an epitaxial growth process has been shown to suppress radial growth and improve the morphology and optical properties of nanowires. In this paper, we investigate the dynamics of photo-generated charge carriers in a series of indium phosphide nanowires grown with varied HCl fluxes. Time resolved photo-induced luminescence, transient absorption and time resolv

A One Health – One World initiative to control antibiotic resistance : A Chile - Sweden collaboration

Controlling antibiotic resistance is a global concern. The One Health initiative has provided a strategy to deal with this problem efficiently within a country. However, due to the global nature of the problem it is paramount not only to focus on specific countries, but to establish ways to avoid the development of antibiotic resistance in different geographical regions. In this letter, we propose

Circulating Monocyte Chemoattractant Protein-1 and Risk of Stroke : Meta-Analysis of Population-Based Studies Involving 17 180 Individuals

Rationale: Proinflammatory cytokines have been identified as potential targets for lowering vascular risk. Experimental evidence and Mendelian randomization suggest a role of MCP-1 (monocyte chemoattractant protein-1) in atherosclerosis and stroke. However, data from large-scale observational studies are lacking. Objective: To determine whether circulating levels of MCP-1 are associated with risk

Improvement in indices of cellular protection after psychological treatment for social anxiety disorder

Telomere attrition is a hallmark of cellular aging and shorter telomeres have been reported in mood and anxiety disorders. Telomere shortening is counteracted by the enzyme telomerase and cellular protection is also provided by the antioxidant enzyme glutathione peroxidase (GPx). Here, telomerase, GPx, and telomeres were investigated in 46 social anxiety disorder (SAD) patients in a within-subject

Impact of human disturbance on the biogeochemical silicon cycle in a coastal sea revealed by silicon isotopes

Biogeochemical silicon (Si) cycling in coastal systems is highly influenced by anthropogenic perturbations in recent decades. Here, we present a systematic study on the distribution of stable Si isotopes of dissolved silicate (δ30SiDSi) in a highly eutrophic coastal system, the Baltic Sea. Besides the well-known processes, diatom production and dissolution regulating δ30SiDSi values in the water c

Inter-Organizational Relationships as Political Battlefields: How Fragmentation within Organizations Shapes Relational Dynamics between Organizations

Whereas extant theorizing on inter-organizational relational dynamics has highlighted the importance of between-partner differences, we shift attention to within-partner differences. We explore how internal fragmentation – i.e., the existence of multiple coalitions within a partner organization, each with different interests and perspectives – influences the evolution of relational characteristics
