The change of distance between individual graphene oxide sheets due to swelling is the key parameter to explain and predict permeation of multilayered graphene oxide (GO) membranes by various solvents and solutions. In situ synchrotron X-ray diffraction study shows that swelling properties of GO membranes are distinctly different compared to precursor graphite oxide powder samples. Intercalation o

The paper describes a debris-free, efficient laser-produced plasma source emitting EUV radiation. The source is based on a double-stream Xe/He gas-puff. Its properties and spectroscopic signatures are characterized and discussed. The spatio-spectral features of the EUV emission are investigated. We show a large body of results related to the intensity and brightness of the EUV emission, its spatia

In Sierra Leone, West Africa, there are many people with disabilities in need of rehabilitation services after a long civil war. Purpose: The aim of this qualitative study was to explore the experiences of prosthetic and orthotic service delivery in Sierra Leone from the local staff's perspective. Method: Fifteen prosthetic and orthotic technicians working at all the rehabilitation centres providi

Self-association of proteins is strongly affected by long-range electrostatic interactions caused by equilibrium adsorption of small ions such as protons and multivalent metals. By affecting the molecular net charge, solution pH is thus a widely used parameter to tune stability and phase behavior of proteins. We here review recent studies where the charge distribution is perturbed not only by prot

Caloric restriction has been found to be protective against the development of type 2 diabetes mellitus (T2D) in experimental animal studies. However, studies examining this association in humans are limited. In the present study, we examined whether individuals with anorexia nervosa, one marker of severe caloric restriction in humans, have a low incidence of T2D by using several Swedish registrie

In this paper I answer Aranyosi’s (Axiomathes 19(2):223–224, 2009) criticism of my “Is Phosphorus Hesperus?” (Axiomathes 19(1):101–102, 2009).

Background Several new therapeutic options for psoriasis have been tested in clinical trials in recent years. Choice of comparator, study duration and outcome measures are critical for interpreting application of trial results to clinical practice. Objectives We examined whether these trial aspects have changed substantially in recent years in comparison with the past. Methods A systematic search

Background. The overall purpose of the present study was to attain more insight in month-to-month variation of sleep duration and quality in order to improve design and interpretation of, e.g. epidemiological studies using sleep as outcome. Methods. The study design entailed monthly self-reports from 38 (26 women/12 men) daytime workers, who completed the Karolinska Sleep Diary (KSD) once a month

A statistical study of embedded metadata in a sample of more than 4 million HTML Web-pages is reported. The paper tries to determine and quantify the validity of this metadata. Of particular interest is to see if it is trustworthy enough for determining the topic of a Web-page. Datasets are collected by a Web crawler running both as a general and a focused crawler. Metadata fields 'title', 'author

β-Microseminoprotein (MSMB) is an abundant protein in seminal plasma. Most of it is present as a free protein but a small part is bound to cysteine-rich secretory protein 3 (CRISP3) as a non-covalent complex. Even though their physiological function is unknown, both MSMB and CRISP3 have been ascribed roles in prostate carcinogenesis. Thus, several recent experimental studies indicate a tumor-suppr

Simultaneous small-angle and wide-angle X-ray scattering (SAXS and WAXS) were used to measure several properties of the nanoparticles and soot being produced and undergoing condensation and phase changes below a stabilizing cooling plate inserted in an ethylene diffusion flame. From the SAXS data several distinct size modes appeared showing interdependent changes in the size, shape/morphology, and

In this study, we describe a novel gene expression signature of platelet-derived growth factor (PDGF) activated fibroblasts, which is able to identify breast cancers with a PDGF-stimulated fibroblast stroma and displays an independent and strong prognostic significance. Global gene expression was compared between PDGF-stimulated human fibroblasts and cultured resting fibroblasts. The most differen

Although the repair of ventral abdominal wall hernias is one of the most commonly performed operations, many aspects of their treatment are still under debate or poorly studied. In addition, there is a lack of good definitions and classifications that make the evaluation of studies and meta-analyses in this field of surgery difficult. Under the auspices of the board of the European Hernia Society

Abstract in UndeterminedThis paper examines vowel production in Swedish adolescents with cochlear implants. Twelve adolescents with cochlear implants and 11 adolescents with normal hearing participated. Measurements were made of the first and second formants in all the nine long Swedish vowels. The values in hertz were bark-transformed, and two measures of the size of the vowel space were obtained

Age-determinations on a complex array of mafic dykes across the eastern Kaapvaal craton (Olsson et al.. 2010) are complemented herein by field evidence, dyke trend analysis, and petrological characterization of 58 dyke samples. similar to 2.95 Ga SE-trending, a similar to 2.65 Ga E- to SE-radiating, and similar to 1.90 Ga NE-trending swarms can be distinguished. Prominent Archean (similar to 2.95

Background. Human papillomavirus (HPV) types from the Beta- and Gammapapillomavirus genera are common at cutaneous sites. The aim of this study was to analyze the prevalence of these HPV types in oral and nasal samples.Methods. Nasal and oral samples were taken from 312 volunteers of Danish health-care staff (240 women and 72 males, with mean age of 42 years). Of these 311 oral and 304 nasal sampl

Design Stratified cluster randomised controlled trial with clubs as the unit of randomisation. Setting 230 Swedish football clubs (121 in the intervention group, 109 in the control group) were followed for one season (2009, seven months). Participants 4
