Hydrodynamics and mass transfer in liquid-liquid slug flow inside a square microchannel (MC-1, aspect ratio 1) and a rectangular microchannel (MC-2, aspect ratio 2) with identical hydraulic diameter (400 µm) were investigated experimentally. The results showed that the overall volumetric mass transfer coefficient (KLa) in MC-2 was 16.2% lower than that in MC-1 due to enlargement of the dispersed p

Mitochondria are known for their role in ATP production and generation of reactive oxygen species, but little is known about the mechanism of their early involvement in plant stress signaling. The role of mitochondrial succinate dehydrogenase (SDH) in salicylic acid (SA) signaling was analyzed using two mutants: disrupted in stress response1 (dsr1), which is a point mutation in SDH1 identified in

Purpose of review Supplemental oxygen improves survival in patients with chronic obstructive pulmonary disease (COPD) and severe hypoxaemia, but the effect of oxygen therapy in mild or moderate hypoxaemia to reduce symptomatic chronic breathlessness remains unclear. This review provides an overview of recent evidence about the role of oxygen therapy for the relief of chronic breathlessness in adva

Aims Metformin therapy is associated with diffuse intestinal 18F-fluoro-deoxyglucose (FDG) accumulation in clinical diagnostics using routine FDG-PET imaging. We aimed to study whether metformin induced glucose uptake in intestine is associated with the improved glycaemic control in patients with type 2 diabetes. Therefore, we compared the effects of metformin and rosiglitazone on intestinal gluco

Objectives To investigate if frontal plane kinematics are predictive of three dimensional (3D) hip adduction and hip internal rotation during running. Study design Cross-sectional. Setting Biomechanics laboratory. Participants Thirty healthy male runners aged 18–45 years. Main outcome measures Two dimensional (2D) angles in the frontal plane (peak pelvic obliquity, peak hip adduction, peak femoral

Purpose: This study aimed to evaluate the association of socioeconomic status and comorbidities with uncomplicated and complicated diverticular disease (DD) in Sweden. Methods: We identified all individuals aged ≥30 years in Sweden diagnosed with DD between 1997 and 2012 using the Swedish National Population and Housing Census and the Hospital Discharge Register. Data were analyzed by multivariabl

Objective: To provide clinical clues to differential diagnosis in patients with chorea and other movement disorders with blood acanthocytes. Background: Neuroacanthocytosis (NA) is an umbrella term for neurological conditions associated with acanthocytosis. Core NA syndromes, with basal ganglia involvement and in which acanthocytosis is a frequent finding, include autosomal recessive choreaacantho

Psychiatric symptoms and stress are on the increase among Swedish adolescents. We aimed to study the potential effect and feasibility of two Internet-based self-help programmes, one mindfulness based (iMBI) and the other music based in a randomised controlled trial that targeted adolescents. A total of 283 upper secondary school students in two Swedish schools were randomised to either a waiting l

Objective: To study selective regional binding for tau pathology in vivo, using PET with [11C]PBB3 ([11C]methylamino pyridin-3-yl buta-1,3-dienyl benzo[d]thiazol-6-ol) in tauopathies, and in conditions not typically associated with tauopathy. Background: Tau imaging is a promising tool to study the link between tau and neurodegeneration. The specificity of tracers in vivo however remains uncertain

The concept that tumor-initiating cells can co-opt the self-renewal program of endogenous stem cells as a means of enforcing their unlimited proliferative potential is widely accepted, yet identification of specific factors that regulate self-renewal of normal and cancer stem cells remains limited. Using a comparative transcriptomic approach, we identify ZNF521/Zfp521 as a conserved hematopoietic

Background and purpose — Analysis of the revision-free survival of knee and hip prostheses has traditionally been performed using Kaplan–Meier analysis and Cox regression. The competing risk problem that is related to patients who die during follow-up has recently been increasingly discussed, not least with regard to the problem of choosing a suitable statistical method for the analysis. We compar

‘Collective Autonomy in the European Union’ explores the question of collective autonomy by investigating the relationship between collective bargaining and legal regulation and its current evolution in the national contexts and in the EU internal market. The thesis aims at achieving a comprehensive understanding of the notion, function and exercise of collective autonomy and collective bargaining‘Collective Autonomy in the European Union’ explores the question of collective autonomy by investigating the relationship between collective bargaining and legal regulation and its current evolution in the national contexts and in the EU internal market.

The pulp and paper industry is among the world most important industrial sectors. At present it focuses on the production of cellulose pulp fibers and electricity but transforming pulp mills into biorefineries can reduce the use of fossil fuel resources. Adjusting the processes and converting lignocellulosic materials into new environmental friendly products will enable the production of biochemic

There is a strong industrial drive to use cloud computing technologies and concepts for providing timing sensitive services in the networking domain since it would provide the means to share the physical resources among multiple users and thus increase the elasticity and reduce the costs. In this work, we develop a mathematical model for user-stateless virtual network functions forming a forwardin

Stads- och trafikplanering är komplext och som konstaterades inledningsvis i denna rapport har cyklingen generellt sett minskat i Sverige och svenska städer trots målsättningar och ambitioner om motsatsen. En möjlig orsak till detta är att det dels är svårt att skapa sig en samlad överblick över vilka faktorer som påverkar valet att cykla, dels är svårt att skapa sig en samlad överblick över hur d

During the past few decades systemic corruption has come to be seen as a significant factor which hinders socio-economic development, posing a serious threat to the political, economic and social well-being of many developing and transition countries. Under conditions of systemic corruption, many institutions, rules and norms of behaviour have become adapted to a corrupt modus operandi. Public off
