In 1978 Wolfgang Helfrich published a paper (Helfrich W. Z Naturforsch 1978; 33a:305) where he introduced the notion of an undulation force between bilayers. This is caused by thermal excitations of the bending modes being restricted by the presence of neighboring layers. Although there is now a consensus on the qualitative picture put forward by Helfrich there is still a debate concerning the qua
Downscaled climate model projections from phase 5 of the Coupled Model Intercomparison Project (CMIP5) were used to force a dynamic vegetation agricultural model (Agro-IBIS) and simulate yield responses to historical climate and two future emissions scenarios for maize in the U.S. Midwest and wheat in southeastern Australia. In addition to mean changes in yield, the frequency of high- and low-yiel
Background: As new combinations of inhaled corticosteroids (ICSs) and long-acting beta(2)-agonists (LABAs) become available for the treatment of asthma, it will be important to determine criteria against which they can be evaluated. The aim of this study was to assess which attributes of combination therapy physicians consider most important. Methods: Primary and secondary care asthma specialists
This article examines the modern concept of literary value. Since the late 18th century, the problem of literary value has been regarded, from the point of view of the so called double discourse of value, as a presupposed opposition between material and spiritual ”economies”. Many Romanticist and Modernist authors believe that literature – and in a broader sense art and aesthetics – constitute a v
In the mid 2000s the oil and gas industry was hit by what might be best described as a 'wall of cash' as oil prices successively reached new record levels and access to external financing improved greatly. In this article we investigate what this sudden abundance of liquidity implied for the investment-cash flow relationship, the interpretation of which continues to generate controversy in the lit
Abstract Aim: The aim of this study was to explore experiences of mobility device (MD) use among very old single-living Swedish men. Methods: A multiple case study of three men, involving quantitative and qualitative data, was used in an embedded mixed methods design and presented in three narrative stories. To capture differences and similarities in the use of MDs a cross-case analysis was conduc
To study the relationship between macular function assessed by multifocal electroretinogram (mfERG) and morphological changes evaluated with optical coherence tomography (OCT) and fundus photography in patients with drusen maculopathy.
In the Bas-Draa Inlier (Anti-Atlas, Morocco), the Paleoproterozoic basement which is cut by the Ediacaran Taourgha granite is also crosscut by numerous dykes of a variety of trends, mostly of uncertain age. Two doleritic dykes are dated by the ID-TIMS U-Pb method on baddeleyite and yield emplacement ages of 1381 +/- 8 Ma (MSWD = 0.84) and 1384 +/- 6 Ma (MSWD = 1.4) determined for a N135 degrees E
The X chromosome (chrX) represents one potential source for the "missing heritability" for complex phenotypes, which thus far has remained underanalyzed in genome-wide association studies (GWAS). Here we demonstrate the benefits of including chrX in GWAS by assessing the contribution of 404,862 chrX SNPs to levels of twelve commonly studied cardiometabolic and anthropometric traits in 19,697 Finni
Arctic areas of deep-water convection have a large potential for export of organic carbon from surface waters into the deep sea and, therefore, are an important part of the global carbon cycle. As the Arctic is reportedly heating up faster than any other part of the planet, temperature-driven changes in the biogeochemical cycling in these areas can be very significant. Here, we study the regulatio
The evolution of striking phenotypes on islands is a well-known phenomenon, and there has been a long-standing debate on the patterns of body size evolution on islands. The ecological causes driving divergence in insular populations are, however, poorly understood. Reduced predator fauna is expected to lower escape propensity, increase body size and relax selection for crypsis in small-bodied, ins
The prognosis for malignant gliomas remains poor, and new treatments are urgently needed. Targeted suicide gene therapy exploits the enzymatic conversion of a prodrug, such as a nucleoside analog, into a cytotoxic compound. Although this therapeutic strategy has been considered a promising regimen for central nervous system (CNS) tumors, several obstacles have been encountered such as inefficient
Optimal single electron sources emit regular streams of particles, displaying no low-frequency charge current noise. Because of the wave packet nature of the emitted particles, the energy is, however, fluctuating, giving rise to heat current noise. We investigate theoretically this quantum source of heat noise for an emitter coupled to an electronic probe in the hot-electron regime. The distributi
Background and purpose - Hip dislocation in children with cerebral palsy (CP) is a common and severe problem. The Swedish follow-up program for CP (CPUP) includes standardized monitoring of the hips. Migration percentage (MP) is a widely accepted measure of hip displacement. Coxa valga and valgus of the femoral head in relation to the femoral neck can be measured as the head-shaft angle (HSA). We
This paper provides a systematic review of scholarly literature concerning the enforcement of children’s rights in the classroom context and school management. The literature review is based on a systematic review methodology the authors developed drawing on the methods and guidelines used in the medical sciences over the last 15 years. Forty-two articles published between 1990 and 2014 were selec
The rare but clinically important null phenotypes of the P1PK and GLOB blood group systems are due to alterations in A4GALT and B3GALNT1, respectively. A recently identified single-nucleotide polymorphism in Exon 2a of A4GALT predicts the common P1 and P2 phenotypes but rare variants have not been tested.
Elevated low-density lipoprotein cholesterol (LDL-C) is a treatable, heritable risk factor for cardiovascular disease. Genome-wide association studies (GWASs) have identified 157 variants associated with lipid levels but are not well suited to assess the impact of rare and low-frequency variants. To determine whether rare or low-frequency coding variants are associated with LDL-C, we exome sequenc
Variation of mechanical properties in materials can be detected non-destructively using ultrasonic measurements. In particular, changes in elastic wave velocity can occur due to damage, i.e., micro-cracking and particles debonding. Here the challenge of characterizing damage in geomaterials, i.e., rocks and soils, is addressed. Geomaterials are naturally heterogeneous media in which the deformatio
