Effect of misfit strain in (Ga,Mn)(Bi,As) epitaxial layers on their magnetic and magneto-transport properties

Effect of misfit strain in the layers of (Ga,Mn)(Bi,As) quaternary diluted magnetic semiconductor, epitaxially grown on either GaAs substrate or (In,Ga)As buffer, on their magnetic and magneto-transport properties has been investigated. High-resolution X-ray diffraction, applied to characterize the structural quality and misfit strain in the layers, proved that the layers were fully strained to th

Internal gravity-capillary solitary waves in finite depth

We consider a two-dimensional inviscid irrotational flow in a two layer fluid under the effects of gravity and interfacial tension. The upper fluid is bounded above by a rigid lid, and the lower fluid is bounded below by a rigid bottom. We use a spatial dynamics approach and formulate the steady Euler equations as a Hamiltonian system, where we consider the unbounded horizontal coordinate x as a t

Theoretical Predictions of Temperature-Induced Gelation in Aqueous Dispersions Containing PEO-Grafted Particles

In this work, we utilize classical polymer density functional theory (DFT) to study gelation in systems containing colloidal particles onto which polymers are grafted. The solution conditions are such that the corresponding bulk system displays a lower critical solution temperature (LCST). We specifically compare our predictions with experimental results by Shay et al. (J. Rheol. 2001, 45, 913-927

MSC from fetal and adult lungs possess lung-specific properties compared to bone marrow-derived MSC

Mesenchymal stromal cells (MSC) are multipotent cells with regenerative and immune-modulatory properties. Therefore, MSC have been proposed as a potential cell-therapy for bronchiolitis obliterans syndrome (BOS). On the other hand, there are publications demonstrating that MSC might be involved in the development of BOS. Despite limited knowledge regarding the functional role of tissue-resident lu

Uses of wonder in popular science : Cosmos: A Personal Voyage and the origin of life

This paper analyses the use of wonder in the TV-series Cosmos: A Personal Voyage (1980). Popular science has been studied extensively (e.g. Broks 2006; Leane 2007; Perrault 2013), and wonder has been studied moderately (e.g. Daston & Park 1998; Fuller 2006; Vasalou 2015). However, there are very few studies of wonder in popular science. This paper explores how and why wonder is used in Cosmos,

Pharmaceutical co-crystals of the anti-inflammatory drug diflunisal and nicotinamide obtained using supercritical CO2 as an antisolvent

A method based on using supercritical CO2 as an antisolvent (SAS method) is explored as a co-crystallization technique. Co-crystallization is an emerging and powerful technique to improve the physicochemical properties of an active pharmaceutical ingredient. The solid-state and solution co-crystallization methods usually employed present several disadvantages. The one-step SAS method has a low env

The aquaporin splice variant NbXIP1;1α is permeable to boric acid and is Phosphorylated in the N-terminal domain

Aquaporins (AQPs) are membrane channel proteins that transport water and uncharged solutes across different membranes in organisms in all kingdoms of life. In plants, the AQPs can be divided into seven different subfamilies and five of these are present in higher plants. The most recently characterized of these subfamilies is the XIP subfamily, which is found in most dicots but not in monocots. In

To know or not to know – parents’ attitudes to and preferences for prenatal diagnosis

Objective: To highlight expectant parents’ attitudes concerning prenatal diagnosis, what the parents wish to know and what they chose not to know about their unborn baby, also in what form and to what extent they wish for prenatal diagnosis. Background: Parents have to make decisions concerning prenatal diagnosis. Screening programmes change rapidly and there is a need for parental influence on th

Optimal Displacement Parameters in Monte Carlo Simulations

An adaptive algorithm optimizing single-particle translational displacement parameters in Metropolis Monte Carlo simulations is presented. The optimization is based on maximizing the mean square displacement of a trial move. It is shown that a large mean square displacement is strongly correlated with a high precision of average potential energy. The method is here demonstrated on model systems re

Storage stability of freeze-dried, spray-dried and drum-dried skim milk powders evaluated by available lysine

Formation of Maillard products and the influencing factors, which are of crucial importance for both manufacturers and consumers, are still not fully understood. Thus in this study available lysine was used as a marker to monitor the extent of Maillard reactions in freeze-dried, spray-dried and drum-dried skim milk powders during 200 days of storage at highly controlled atmospheres. Storage variab

Analyzing the influence of learning orientation and innovativeness on performance of public organizations : The case of Iran

Purpose – There is growing concern about the performance of public organizations (POs) in developing countries. Despite the fact that the advantages of innovation and learning orientation to organizations have been evidently documented in Western economies and private owned enterprises, there has been little research into these practices and their impact on enhancing competitive advantages in POs

Anomalous temperature behavior in clay swelling due to ion-ion correlations

We show, experimentally and theoretically, that swelling of both natural and refined clays has an anomalous temperature behavior depending on counterion valency. In an aqueous clay dispersion dominated by monovalent counterions the swelling pressure increases with temperature as expected from entropic arguments. In a clay with predominantly divalent counterions, the opposite behavior is found. The

The fan-like forms in the southern margin of the Mazovian Lowland area (Central Poland) : a new high-resolution textural-timing study

An optically stimulated luminescence technique with a high-resolution sampling strategy, as well as a set of multiple proxies such as grain size distribution, shape, surface and microstructures of quartz grains, along with mineral composition of light and heavy fractions was used to investigate the age and origin of fan-like forms at the southern margin of Mazovian Lowland, Poland. The predominanc

Ear-body lift and a novel thrust generating mechanism revealed by the complex wake of brown long-eared bats (Plecotus auritus)

Large ears enhance perception of echolocation and prey generated sounds in bats. However, external ears likely impair aerodynamic performance of bats compared to birds. But large ears may generate lift on their own, mitigating the negative effects. We studied flying brown long-eared bats, using high resolution, time resolved particle image velocimetry, to determine the aerodynamics of flying with

A fast and sensitive method for the separation of carotenoids using ultra-high performance supercritical fluid chromatography-mass spectrometry

In this study, a rapid and sensitive ultra-high performance supercritical fluid chromatography-mass spectrometry (UHPSFC-MS) method has been developed and partially validated for the separation of carotenoids within less than 6 min. Six columns of orthogonal selectivity were examined, and the best separation was obtained by using a 1-aminoanthracene (1-AA) column. The length of polyene chain as we

Microemulsions of Record Low Amphiphile Concentrations Are Affected by the Ambient Gravitational Field

It is shown that the ternary system heavy water-heptane-hexadecyl hexaethylene oxide (C16E6) has a stable bicontinuous microemulsion phase down to an exceptionally low concentration at the balanced temperature of 26.8 °C. It is further demonstrated that the ambient gravitational field has an influence on the observed phase equilibria for typical sample sizes (∼1 cm). Direct measurements using a nu
