The determinants and consequences of the naturalization of immigrants is a hot topic in the political debate in Europe. This article compares the effect of naturalization on the income attainment of immigrants in two Scandinavian countries, Denmark and Sweden, using longitudinal register data from 1986 and onward. Sweden is characterized by low obstacles to naturalization, and existing studies pro
Stemflow of xerophytic shrubs represents a significant component of water replenishment to the soil-root system influencing water utilization of plant roots at the stand scale, especially in water scarce desert ecosystems. In this study, stemflow of Caragana korshinskii was quantified by an aluminum foil collar collection method on re-vegetated sand dunes of the Shapotou restored desert ecosystem
Although nanowires are widely used in biological applications, especially as cell-manipulation tools, the effect of nanowires on living cells has not been fully investigated. Here, we examined the full gene expression of mouse cortical stem cells cultured on vertical nanowire substrates using RNA microarrays. Genes involved in cell adhesion, cell morphology regulation and cell metabolism were up r
Magnetic compass orientation in a night-migratory songbird requires that Cluster N, a cluster of forebrain regions, is functional. Cluster N, which receives input from the eyes via the thalamofugal pathway, shows high neuronal activity in night-migrants performing magnetic compass-guided behaviour at night, whereas no activation is observed during the day, and covering up the birds' eyes strongly
Objectives To investigate, using a Dutch model, whether and under what variables framed for other European countries screening for human papillomavirus (HPV) is preferred over cytology screening for cervical cancer, and to calculate the preferred number of examinations over a woman's lifetime. Design Cost effectiveness analysis based on a Dutch simulation model. Base case analyses investigated the
In the past two decades, centres of excellence (CoE) and other ‘research excellence initiatives’ likely to increase the cumulative advantages and stratification of science, have been implemented in many countries. Based on empirical studies of CoE in four Nordic countries, this paper examines how the resources provided by CoE schemes (generous long-term funding, prestige and visibility) add to the
We calculated a simple indicator of food availability using data from 93 sites in 17 countries across contrasted agroecologies in sub-Saharan Africa (>13,000 farm households) and analyzed the drivers of variations in food availability. Crop production was the major source of energy, contributing 60% of food availability. The off-farm income contribution to food availability ranged from 12% for hou
This article analyses a divergent supply chain consisting of a central warehouse and N nonidentical retailers. The focus is on joint evaluation of inventory replenishment and shipment consolidation effects. A time-based dispatching and shipment consolidation policy is used at the warehouse in conjunction with real-time point-of-sale data and centralized inventory information. This represents a com
The currently used patch test concentration of formaldehyde (1.0% aqua; 0.30 mg/cm(2) ) has been shown to fail to detect ˜ 50% of contact allergies to formaldehyde.
Peptidoglycan is the major structural component of the bacterial cell wall. Penicillin-binding proteins (PBPs), located at the exterior of the cytoplasmic membrane, play a major role in peptidoglycan synthesis and remodelling. A PASTA domain (penicillin-binding protein and serine/threonine kinase associated domain) of about 65 residues is found at the C-terminal end of some PBPs and eukaryotic-lik
The molecular and emulsifying properties of gum arabic (GA) and mesquite gum (MG) were characterized using asymmetrical flow field-flow fractionation connected to multi-angle light scattering and refractive index detection. Properties such as molar mass, root-mean-square radius (rrms), hydrodynamic radius (rh), conformation, apparent densities and distribution of proteinaceous matter over the whol
Cytokeratin 20 (CK20) is a well-established marker for colon epithelium. Herein, we suggest that CK20 is a biomarker for detecting circulating tumor cells (CTCs) in patients with metastatic colorectal cancer. Blood specimens (7.5 mL) were collected during surgery after liver mobilization from 25 patients with colorectal cancer. The FDA approved CellSearch™ system and two panels of antibodies again
The reliability of some methods of neurological prognostication after out-of-hospital cardiac arrest has been questioned since the introduction of induced hypothermia. The aim of this study was to determine whether different treatment temperatures after resuscitation affected the prognostic accuracy of clinical neurological findings and somatosensory evoked potentials (SSEP) in comatose patients.
BackgroundStandard treatment of adult Burkitt lymphoma is not defined due to the lack of randomised trials. In this situation, population-based data may represent a useful contribution in order to identify an optimal treatment strategy.Patients and methodsThe aims of this study were to investigate the outcome for adult HIV-negative BL with different chemotherapy regimens, and to assess possible im
OBJECTIVE: The surgical management of adults with congenital heart disease (ACHD) offers a great challenge, with a large number of anomalies with complex pathophysiology necessitating specific treatments. Pre- and postoperative morbidity has been relatively high, and the influencing factors are not completely identified. We sought to evaluate the incidence and predictors of postoperative complicat
Hypothesis: Sodium dioctylsulfosuccinate (Aerosol OT or NaAOT) is a well-studied charging agent for model poly(methyl methacrylate) (PMMA) latexes dispersed in nonpolar alkane solvents. Despite this,few controlled variations have been made to the molecular structure. A series of counterion exchanged analogs of NaAOT with other alkali metals (lithium, potassium, rubidium, and cesium) were prepared,
