O/W emulsions stabilized by OSA-modified starch granules versus non-ionic surfactant : Stability, rheological behaviour and resveratrol encapsulation

Resveratrol is a natural phenol with many positive effects for human health. However it is a photosensitive molecule with geometric isomerism, easily oxidised with short biological half-life and rapid metabolism and elimination. Thus, encapsulation of resveratrol is necessary. It has low solubility in water and in most of common oils. The goal of this work was to prepare oil-in-water emulsion stab

Sustainability of mega water diversion projects : Experience and lessons from China

Water availability and water demand are not evenly distributed in time and space. Many mega water diversion projects have been launched to alleviate water shortages in China. This paper analyzes the temporal and spatial features of 59 mega water diversion projects in China using statistical analysis. The relationship between nine major basins is measured using a network analysis method, and the as

Allies and competitors: Private schools and the state in China

The term ‘private school’ as used in the Chinese context denotes a wide variety of schools, reaching from schools for poor rural children, to those for migrant children with external residency, to schools for children from the middle and upper classes seeking an education beyond the ordinary. Even though Chinese education has not undergone any large-scale privatization, an increasing number of fam

Curse or Blessing? Chinese Academic Responses to China’s PISA Performance

This chapter will look at the academic responses to China’s PISA performance as articulated in Chinese academic journals and educational newspapers. These responses belong largely to four different types: (i) Learning from PISA and its implications for assessing educational quality; (ii) establishing China as an educational role model; (iii) contrasting the Chinese system’s exam-efficiency with in

The effect of the relative permittivity on the tactoid formation in nanoplatelet systems. A combined computer simulation, SAXS, and osmotic pressure study

The structural properties, and the intracrystalline swelling of Na+-, and Ca2+-montmorillonite (Na-, and Ca-mmt) have been investigated as an effect of decreasing the relative permittivity of the solvent, i.e. from water to ethanol (EtOH), utilizing the experimental techniques; small angle X-ray scattering (SAXS) and osmotic pressure measurements. The experimental data were compared with the conti

Stiffness optimization of non-linear elastic structures

This paper revisits stiffness optimization of non-linear elastic structures. Due to the non-linearity, several possible stiffness measures can be identified and in this work conventional compliance, i.e. secant stiffness designs are compared to tangent stiffness designs. The optimization problem is solved by the method of moving asymptotes and the sensitivities are calculated using the adjoint met

The effects of multiple stressors on the distribution of coastal benthic foraminifera : A case study from the Skagerrak-Baltic Sea region

Coastal ecosystems are subjected to both large natural variability and increasing anthropogenic impact on environmental parameters such as changes in salinity, temperature, and pH. This study documents the distribution of living benthic foraminifera under the influence of multiple environmental stressors in the Skagerrak-Baltic Sea region. Sediment core tops were studied at five sites along a tran

Membrane interactions of microgels as carriers of antimicrobial peptides

Microgels are interesting as potential delivery systems for antimicrobial peptides. In order to elucidate membrane interactions of such systems, we here investigate effects of microgel charge density on antimicrobial peptide loading and release, as well as consequences of this for membrane interactions and antimicrobial effects, using ellipsometry, circular dichroism spectroscopy, nanoparticle tra

On the rheology of mixed systems of hydrophobically modified polyacrylate microgels and surfactants : Role of the surfactant architecture

Hypothesis The rheological control of suspensions is of key interest in the formulation design. A chemically cross-linked hydrophobically modified poly(acrylic acid) (HMCL-PAA), used as rheology modifier, is pH sensitive and shows swelling behavior above a critical pH due to the ionization of the acrylic acid groups. At low pH, HMCL-PAA suspensions are liquid and turbid. The binding of surfactants

Experimental and modeling studies of a biofuel surrogate compound : laminar burning velocities and jet-stirred reactor measurements of anisole

Lignocellulosic biomass is a promising alternative fuel source which can promote energy security, reduce greenhouse gas emissions, and minimize fuel consumption when paired with advanced combustion strategies. Pyrolysis is used to convert lignocellulosic biomass into a complex mixture of phenolic-rich species that can be used in a transportation fuel. Anisole (or methoxybenzene) can be used as a s

Molecularly imprinted TiO2 photocatalysts for degradation of diclofenac in water

In order to improve the selectivity in photocatalytic process, molecularly imprinted photocatalysts containing a low loading of TiO2 (from 6.6 to 16.6% of total mass) were prepared for photocatalytic degradation of an organic pollutant, diclofenac (DIC). The photocatalytic component TiO2 (P25), with and without being doped with Cu2O, was embedded in diclofenac-imprinted polymers. The molecularly i

Envisioned, enacted & stated practices: ‘Creativity’/’innovation’ and the social-political ecosystem of teaching

Ethnographic (and other) studies on teachers often rely on two kinds of material: observations of teaching practices in the classroom; and statements about teaching practices, extracted both from involved actors (e.g. teacher interviews) and from documents (e.g. educational policy documents or teaching manuals). Many scholars agree that there is a discrepancy between what is stated, or desired, pr

Critical biomass harvesting – Applying a new concept for Swedish forest soils

The contribution of forest harvesting to base cation losses and soil acidification has increased in recent years in Sweden, as the demand for bioenergy has increased and the sulphur deposition has decreased. Thus, new policy tools are required to evaluate the progress of the recovery from acidification, and as a basis for forest management recommendations. In this study we introduce and test a con

Education & New Technologies in China: The Politics of Visions & Strategies

In the Western hemisphere, the opposition of surveillance versus privacy appears to be common sense: any technology use with the potential risk of infringing upon personal integrity and privacy is in return expected to lead to substantial improvements in security in order to constitute a legitimate course of action. In China, the main problem of inhibiting the free flow of information is rarely se

Industrialized Building Companies' Business Models : Multiple Case Study of Swedish and North American Companies

Industrialized building companies apply various product predefinition strategies, derived from market- or resource-based strategic perspectives. This strongly affects the buildup of such companies' business models and their operational structure. Ten companies were included in a case study, presenting strategic orientations and business models. The aim of this study was to analyze the primary char

Cell immobilization on 3D-printed matrices : A model study on propionic acid fermentation

This study uses three-dimensional (3D) printing technology as a tool for designing carriers for immobilization of microbial cells for bioprocesses. Production of propionic acid from glucose by immobilized Propionibacterium sp. cells was studied as a model system. For cell adsorption, the 3D-printed nylon beads were added to the culture medium during 3 rounds of cell cultivation. Cell adsorption an

Lay theories in comparative research

The paper addresses the theoretical concept and methodological usefulness of 'lay theories' for conducting comparative research. 'Lay knowledge' is a well-researched concept particularly in medicine and health (e.g. Williams & Popay 2006), even if often regarded as an 'obstacle' that needs to be overcome in order to spread 'proper' scientific, medical knowledge. Critical studies within medicin
