Local variation in Bi crystal sites of epitaxial GaAsBi studied by photoelectron spectroscopy and first-principles calculations

Epitaxial Bi-containing III–V crystals (III-V1-xBix) have attracted increasing interest due to their potential in infrared applications. Atomic-scale characterization and engineering of bulk-like III-V1-xBix properties (e.g., Bi incorporation and defect formation) are challenging but relevant to develop applications. Toward that target, we report here that the traditional surface-science measureme

Transverse instability of periodic and generalized solitary waves for a fifth-order KP model

We consider a fifth-order Kadomtsev–Petviashvili equation which arises as a two-dimensional model in the classical water-wave problem. This equation possesses a family of generalized line solitary waves which decay exponentially to periodic waves at infinity. We prove that these solitary waves are transversely spectrally unstable and that this instability is induced by the transverse instability o

Analysis of β-glucan molar mass from barley malt and brewer's spent grain with asymmetric flow field-flow fractionation (AF4) and their association to proteins

β-Glucan benefits are related with its molar mass and it would be of interest to better understand how this parameter can be changed by processing and variety for design of food with specific health effects. For this purpose, extracts from barley malts and brewers' spent grain, processed at different conditions, were analysed regarding β-glucan content, molar mass, and protein content. Molar mass

Production of starch nanoparticles by dissolution and non-solvent precipitation for use in food-grade Pickering emulsions

The aim of this study was to investigate non-solvent precipitation of starch to produce nanoparticles that could be used in Pickering emulsions. The material used was waxy maize, modified with octenyl succinic anhydride. Different methods of non-solvent precipitation were investigated, and a method based on direct mixing of an 8% starch solution and ethanol (ratio 1:1) was found to produce the sma

Study protocol : Differential effects of diet and physical activity based interventions in pregnancy on maternal and fetal outcomes: Individual patient data (IPD) meta-analysis and health economic evaluation

BackgroundPregnant women who gain excess weight are at risk of complications during pregnancy and in the long term. Interventions based on diet and physical activity minimise gestational weight gain with varied effect on clinical outcomes. The effect of interventions on varied groups of women based on body mass index, age, ethnicity, socioeconomic status, parity, and underlying medical conditions

Facile synthesis of novel soluble cellulose-grafted hyperbranched polymers as potential natural antimicrobial materials

A new class of soluble cellulose-grafted hyperbranched polymers has been synthesized by a facile “hypergrafting” reaction using bis(2-chloroethyl)amine and soluble cellulose tosylates. The molecular structures of the obtained new materials were characterized by 13C NMR, FTIR spectroscopy, and elemental analysis. The degree of substitution of the hyperbranched cellulose derivatives ranges between 0

Microstructure, crystallographic texture and mechanical behaviour of friction stir processed Mg-Zn-Ca-Zr alloy ZKX50

The feasibility of applying friction stir processing (FSP) to locally homogenise and to refine the microstructure of a recently developed Mg-Zn-Ca(-Zr) alloy, ZKX50, has been examined. The application of a single pass of FSP resulted in dissolution of coarse intermetallic particles at dendrite boundaries and grain refinement, from an average grain size of ~60 µm in the as-cast state to ~1.2 µm. Th

Cubosomes for in vivo fluorescence lifetime imaging

Herein we provided the first proof of principle for in vivo fluorescence optical imaging application using monoolein-based cubosomes in a healthy mouse animal model. This formulation, administered at a non-cytotoxic concentration, was capable of providing both exogenous contrast for NIR fluorescence imaging with very high efficiency and chemospecific information upon lifetime analysis. Time-resolv

Peak-to-valley ratios for three different HPGe detectors for the assessment of 137Cs deposition on the ground and the impact of the detector field-of-view

The peak-to-valley (PTV) method was investigated experimentally comparing PTV ratios for three HPGe detectors, with complementary Monte Carlo simulations of scatter in air for larger source-detector distances. The measured PTV ratios for 137Cs in air were similar for three different detectors for incident angles between 0 and 90°. The study indicated that the PTV method can differentiate between s

Regulatory Trust in EU Free Movement Law: Adopting the Level of Protection of the Other?

The principles of mutual trust and mutual recognition are well established features of EU law. On a technical level, it is clear that the principles may require adoption of foreign levels of protection in individual cases as well as in legislation. At a closer look, however, the principles through “the rule of reason” also may imply quite the opposite: the imposing of domestic requirements on fore

Multidimensional diffusion MRI

Principles from multidimensional NMR spectroscopy, and in particular solid-state NMR, have recently been transferred to the field of diffusion MRI, offering non-invasive characterization of heterogeneous anisotropic materials, such as the human brain, at an unprecedented level of detail. Here we revisit the basic physics of solid-state NMR and diffusion MRI to pinpoint the origin of the somewhat u

Evidence against observational spatial memory for cache locations of conspecifics in marsh tits Poecile palustris

Abstract: Many species in the family Paridae, such as marsh tits Poecile palustris, are large-scale scatter hoarders of food that make cryptic caches and disperse these in large year-round territories. The perhaps most well-known species in the family, the great tit Parus major, does not store food itself but is skilled in stealing caches from the other species. We have previously demonstrated tha

Response of moist paperboard during rapid compression and heating

The response of moist paperboard exposed to extensive compression and heating in short periods of time is investigated. A generic framework describing this response, in a thermodynamically consistent manner, has been derived previously. The present paper provides explicit formats of the necessary constitutive relations specific to moist paperboard exposed to extensive compression and heating in sh

Wåhlins värld : Ett porträtt i ord och bild av domkyrkoarkitekt Theodor Wåhlin

En fotobok om en av Lunds, Malmös och faktiskt hela Skånes mest betydelsefulla men numera bortglömda arkitekter; Theodor Wåhlin (1864–1948). Med 80 utvalda fotografier, tagna av Wåhlin själv mellan 1880- och 1930-talet, ger boken för första gången en både estetisk och biografisk helhetsbild av såväl hans yrkes som privatliv.

Design of a potentially prebiotic and responsive encapsulation material for probiotic bacteria based on chitosan and sulfated β-glucan

Hypothesis Chitosan and sulfated oat β-glucan are materials suitable to create a prebiotic coating for targeted delivery to gastrointestinal system, using the layer by layer technology. Experiment Quartz crystal microbalance with dissipation (QCM-D), spectroscopic ellipsometry (SE) and atomic force microscopy (AFM) were used to assess the multilayer formation capacity and characterize the resultin
