French as cL2, 2L1 and L1 in pre-school children

Compared to monolingual first language acquisition (L1) and adult second language acquisition (aL2), relatively little research has been done on child second language acquisition (cL2). This is an unsatisfactory situation from both a practical and a theoretical point of view. The present study concerns cL2 acquisition of French and poses the question whether cL2 acquisition bears closer resemblanc

Stochastic Modeling and Operational Optimization in District Heating Systems

Operation of a district heating system is accomplished via a sequence of decisions by the operators controlling the system. These decisions are based on expectations of conditions in the system that are not known at decision time. The operators could be helped by a decision support system that computes predictions of future system variables and suggests appropriate control actions given the availa

Genome-wide association study identifies six new loci influencing pulse pressure and mean arterial pressure

Numerous genetic loci have been associated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) in Europeans(1-3). We now report genome-wide association studies of pulse pressure (PP) and mean arterial pressure (MAP). In discovery (N = 74,064) and follow-up studies (N = 48,607), we identified at genome-wide significance (P = 2.7 x 10(-8) to P = 2.3 x 10(-13)) four new PP loci (at

Selective determination of acidic pharmaceuticals in wastewater using molecularly imprinted solid-phase extraction.

The determination of acidic pharmaceuticals, such as non-steroidal anti-inflammatory drugs NSAIDs and clofibric acid (metabolite of clofibrate), at low ngL(-1) levels in wastewater requires highly selective and sensitive analytical procedures. The removal of matrix components during sample preparation results in significant benefits towards reducing the matrix effects during LC-MS analysis. Theref

Trouble in School: Law, Policy and the Dynamics of Everyday Life at School

Abstract/Results. The paper discusses the results of three different studies. A study of 717 ninth grade students in eight schools located in different socio-economic environments show that students have a low degree of trust in dispute settlement forms available at school. When involved in conflicts or degrading treatment at school they avoid turning to the school for help. Students give themselv

Critical parameters in blood processing for T-cell assays: Validation on ELISpot and tetramer platforms

Assays detecting antigen (Ag)-specific T-cell responses in immune-mediated processes are increasingly employed to understand disease pathogenesis and "immune staging". The quantity and quality of starting peripheral blood mononuclear cell (PBMC) preparations are important factors in the performance of such assays. We therefore compared final PBMC yield and function by modifying parameters at the b

Construction of laboratories for solar energy research in developing countries

A large number of photovoltaic systems have been installed in developing countries around the world during numerous projects. The goal is often to improve the quality of life in rural areas often lacking electricity. Many of these installations provide important services such as lighting and charging of various devices. However, when the projects are finished, there is a large risk that maintenanc

Genetics of complications in patients with type 2 diabetes

Popular Abstract in English Type 2 diabetes (T2D) is a polygenic disorder characterized by impaired insulin secretion or insulin action in which genes interact with the environment to cause the disease. T2D represent 90% of all patients with diabetes. The disease is increasing globally, with an estimated prevalence of 592 million affected by 2035. According to World Health Organization records, apType 2 diabetes (T2D) is a polygenic disease caused by an interaction between genetic and environmental factors such as low physical activity, smoking, and obesity. The disease is associated with devastating chronic microvascular (nephropathy, retinopathy, and neuropathy) and macrovascular (coronary heart disease and stroke) complications. Genome-wide associated studies (GWASs) have been an unbias

The secondary structure of apolipoprotein A-I on 9.6-nm reconstituted high-density lipoprotein determined by EPR spectroscopy

ApolipoproteinA-I (ApoA-I) is the major protein component of high-density lipoprotein (HDL), and is critical for maintenance of cholesterol homeostasis. During reverse cholesterol transport, HDL transitions between an array of subclasses, differing in size and composition. This process requires ApoA-I to adapt to changes in the shape of the HDL particle, transiting from an apolipoprotein to a myri

Lighting control systems in individual offices at high latitude: measurements of lighting conditions and electricity savings

An efficient lighting control systems (LCS) should take advantage of the natural light available, but this presents some technical challenges as well as user related issues. So far, the assessment of lighting energy consumption of LCS has been based on technical features rather than the occupants’ acceptance. This article presents the results of a monitoring study providing some recommendations ba

Personality disorder features as predictors of symptoms five years post-treatment.

Personality disorders are associated with dysfunction in a variety of areas. Recent longitudinal research has shown that personality disorders are also predictive of problems later in life, as well as of poor response to treatment of depression and anxiety. This study assessed whether personality disorder features were associated with psychiatric symptoms in a cohort of women treated for substance
