A review of in situ real-time monitoring techniques for membrane fouling in the biotechnology, biorefinery and food sectors

Pressure-driven membrane processes are often used for the separation and purification of organic compounds originating from biomass. However, membrane fouling remains a challenge as these bio-based streams have a very complex composition and comprise a high fouling tendency. Conventional, the fouling is monitored based on either a decrease in flux or an increase in pressure over time. Those conven

A SEMI-ANALYTIC MODEL OF TIDAL INLETS AND THEIR EVOLUTION

The water exchange between the sea and a lagoon or bay through an inlet due to tides is a classical topic that has been investigated in a large number of studies (Keulegan, 1967; O’Brien and Dean, 1972; O’Brien and Clark, 1974; Escoffier, 1977). In this paper, a simple semi-analytic model of the flow induced by tides through an inlet connecting the sea to a lagoon or bay is developed. The model is

A Single-Electron Transistor Made of a 3D Topological Insulator Nanoplate

Quantum confined devices of 3D topological insulators are proposed to be promising and of great importance for studies of confined topological states and for applications in low-energy-dissipative spintronics and quantum information processing. The absence of energy gap on the topological insulator surface limits the experimental realization of a quantum confined system in 3D topological insulator

Bile but not chyle lipoprotein is an important source of arachidonic acid for the rat small intestine

Arachidonic acid (AA) functions as a structural component, eicosanoid precursor and surface material for chylomicron production in the gastrointestinal tract. The origin of this AA is poorly characterized. [3H]AA labelled chylomicrons and [14C]AA albumin-FFA were injected intravenously into biliary diverted rats and controls. Radioactivity in tissue lipids was measured after different time interva

Den nya ekonomin i ett historiskt perspektiv

Den nya ekonomin har inspirerat till djärva utsagor om vår ekonomiska framtid. Här granskas fem sådana utifrån ett historiskt perspektiv. Hur påverkar den nya ekonomin följande fem fenomen: konjunkturcykeln, de ekonomiska kriserna, inflationen, stabiliseringspolitiken samt den svenska modellen? Svaren är förvisso preliminära men pekar på att den nya ekonomin på vissa områden inte leder till någon

Structural control of charge storage capacity to achieve 100% doping in vapor phase-polymerized PEDOT/tosylate

Vapor phase polymerization (VPP) is used to fabricate a series of tosylate-doped poly(3,4-ethylenedioxythiophene) (PEDOT) electrodes on carbon paper. The series of VPP PEDOT/tosylate coatings has varying levels of crystallinity and electrical conductivity because of the use (or not) of nonionic triblock copolymers in the oxidant solution during synthesis. As a result, the impact of the structure o

Software Defined Networking for Emergency Traffic Management in Smart Cities

Vehicle traffic management is becoming more complex due to increased traffic density in cities. Novel solutions are necessary for emergency vehicles, which despite growing congestion must be able to quickly reach their destination. Emergency vehicles are usually equipped with transmitters to control the traffic lights on their path and warn other vehicles with sirens. Transmitters are operated man

Gendered Career Rein: : A Gender Analysis of the Certification Process of Auditors in Sweden

It has been claimed that the accounting and auditing business is a gendered industry. Even though as many women as men enter the business, high positions such as partnerships still largely appear to be a privilege for men. Earlier research has indicated that this selection process starts early on the career ladder. In this article we investigate the gendered character of the early phase of qualifi

The Role of Local Governments in Governing Sustainable Consumption and Sharing Cities

Municipalities are key actors in their role as planners for sustainable urban development, and also have the responsibility to transform ambitious national and global goals and visions into local practices (McCormick et al., 2013). The role of municipalities in relation to enhancing sustainable consumption patterns has been increasingly highlighted by policy-makers and in research. Creating sustai

Mental health provision in schools: priority, facilitators and barriers in 10 European countries

Background: Although schools are a key setting for the provision of mental health support for young people, little is known about the facilitators and barriers for providing such support. This study aimed to collect information from schools in 10 European countries regarding the priority given to mental health support for students, existence of a mental health‐related school policy, links with rel

Spurring remanufacturing through public procurement – A case study in the Swedish automotive industry

There is a growing political consensus in the European Union (EU) to move away from the current resource intensive “linear” economic system, towards an innovative system aiming at closing material loops – the so-called circular economy. An array of new policy proposals targeting all stages of the life-cycle of a product are needed to facilitate the transition to a circular economy in Europe. While

Employees as ambassadors: embracing new role expectations and coping with identity-tensions

PurposeTo provide an employee perspective on ambassadorship in the context of corporate communication, the purpose of this paper is to explore how employees relate to and experience ambassadorship.Design/methodology/approachThe study has a qualitative approach, and the empirical material consists of semi-structured interviews with, and focus groups of, employees of seven organizations in both the

Taking Action for Urban Nature: Innovation Pathways Directory

What are the enabling conditions and driving forces for nature-based solutions in the context of urban sustainability transitions? And how do innovation pathways play a role for nature-based solutions? Innovation pathways are a journey: from the initial idea and its demonstration, to its broader uptake within policy, industry and society. The Innovation Pathways Directory provides an entry point t

Maternal dietary selenium intake is associated with increased gestational length and decreased risk for preterm delivery

The first positive genome-wide association study on gestational length and preterm delivery showed associations with a gene involved in the selenium metabolism. In this study we examine the associations between maternal intake of selenium and selenium status with gestational length and preterm delivery in 72,025 women with singleton live births from the population based, prospective Norwegian Moth
