Towards alkali-stable polymers and hydroxide exchange membranes functionalized with alicyclic quaternary ammonium cations

In the current work, cationic polymers functionalized with N-alicyclic quaternary ammonium (QA) cations were synthesized and characterized as potential hydroxide exchange membranes (HEMs) for application in fuel cells. Three different polymers, namely poly(arylene ether sulfone), spiro-ionene and poly(arylene alkylene), were explored as polymer backbones for the HEMs. Various mono- and spirocyclic

Going beyond science-policy interaction? : An analysis of views among intergovernmental panel on climate change actors

Scholarly literature on science-policy interaction is typically dividedbetween advocating that science and policy need to be broughtcloser together or separated. In a recent article in this journal,Sundqvist and colleagues [Sundqvist et al. (2018) Oneworld ortwo? Science–policy interactions in the climate field, Critical PolicyStudies, 12:4, 448–468] proposed a typology that structures thisdebate.

From individuals to the organization: A transactive memory system perspective on multilevel entrepreneurial learning

This study aims to develop a process model that details the mechanisms and learning processes by which entrepreneurial learning transpires at multiple levels in the organization. Using the transactive memory system (TMS) framework as a reference, the model specifies how individual streams of knowledge are routinized in nonhuman elements and, over time, become embedded in organizational routines an

Catheter-related infections : A Scandinavian observational study on the impact of a simple hygiene insertion bundle

BACKGROUND: Catheter-related infections (CRIs) and catheter-related bloodstream infections (CRBSIs) are among the most frequent hospital acquired infections. CRI/CRBSI studies in Scandinavian cohorts are scarce. The primary aim of this study was to investigate the CRI/CRBSI incidence and the association between potential risk factors, including the introduction of a simple hygiene insertion bundle

Living with street art

Keynote presentation based on the book "Street Art and the Environment" (2018).This keynote talk discussed how street art may influence our perception and use of the urban environment. With a point of departure in the book "The Street Art World" (2014), it argued that the open, unsanctioned and ephemeral nature of street art plays an important role in potentially changing how we relate to our surroundings. The talk also considered how sanctioned, often large-scale, works can

Discourse of Yemeni TV broadcasters and the Dilemma of Regime Criticism, 2015-2019

The discourse of the Yemeni TV broadcasters has been undergoing major changes since the Arab Spring in 2011. However, after the recent civil war, specifically since 2015, this discourse has been diverse, and has become a clear reflection of the contexts in which it is produced. This paper attempts to analyze the Yemeni media discourse by analyzing the titles of the news reports published on YouTub

LGBTQ in Vietnam: Heteronormativity and Resistance

Recent political, legal and social changes have served to illustrate shifting understandings of sexualities in contemporary Vietnam. Such changes have included pride demonstrations; the establishment of organisations working with LGBTQ rights; debates around same-sex marriage and LGBTQ rights; new legislation; and increased openness about same-sex preferences among young people. Despite these rece

Energy, space, and movement : Toward a framework for theorizing energy justice

This paper attempts to assemble a conceptual framework for understanding to what extent an energy technology is simply a way of putting nature to work, and to what extent it is a way of putting other segments of global society to work. The turn to fossil energy reversed the relation between energy and space, as fossil fuels henceforth propelled new transport technologies that provided access to in

Optimal Content Retrieval Latency for Chunk Based Cooperative Content Replication in Delay Tolerant Networks

Modern content distribution networks face an increasing multitude of content generators. In order to reach the minimal content retrieval latency in the content distribution networks, content shall be disseminated towards consumers based on its popularity taken from the content distribution networks. This, Combined with dividing media into chunks (heterogeneous valuation of information) and contact

Trapping of Cell-Laden Hyaluronic Acid-Acrylamide Hydrogel Droplets using Bulk Acoustic Waves

In this paper an acoustofluidic system to trap hydrogel droplets is shown. The presented trapping method is label-free, biocompatible and operated in non-contact mode. The results show that the droplets can be trapped at flow rates up to 76 μL/min which corresponds to an average flow speed of 3.2 mm/s. Moreover, it is shown that the droplets can be trapped for several hours, thus allowing for stud

Towards real-time ADMM for linear MPC

We present a novel predictive control scheme for linear constrained systems that uses the alternating direction method of multipliers (ADMM) for online optimization. In contrast to existing works on ADMM-based model predictive control (MPC), we only consider a single ADMM-iteration in every time step. The resulting real-time ADMM scheme is tailored for embedded and fast MPC implementations. The ma

Exploring causality of the association between smoking and Parkinson's disease

BACKGROUND: The aim of this paper is to investigate the causality of the inverse association between cigarette smoking and Parkinson's disease (PD). The main suggested alternatives include a delaying effect of smoking, reverse causality or an unmeasured confounding related to a low-risk-taking personality trait. METHODS: A total of 715 incident PD cases were ascertained in a cohort of 220 494 indi

Between Malthus and the industrial take‐off: regional inequality in Sweden, 1571–1850

The causes and extent of regional inequality in the process of economic growth are at the core of historical economic research. So far, much attention has been devoted to studying the role of industrialization in driving regional divergence. However, empirical studies on relatively unequal countries such as Italy and Spain show that inequality was already high at the outset of modern industrializa

Moisture safety of wooden buildings – design, construction and operation

During the last decade, building in wood has increased, mainly due to environmental awareness and targets to decrease the carbon footprint originated from the production of building materials. New technologies such as CLT (cross laminated timber) have accelerated the construction of multi-story wooden buildings. The CLT structure has been used both for housing and offices. Due to the extensive siz

Unveiling the process of sustainable renovation

Thuvander, L, Femenias, P, Mjörnell, K, Meiling, P, Unveiling the process of sustainable renovation. Published in open access journal Sustainability 2012, 4(6), in May 2012.Renovation processes are complex and there is a risk of underestimating architectural, cultural, and social values in favor of exterior and interior upgrading, energy efficiency and financing. A synthesized, systematic process is needed for making decisions about renovation measures. The aim of this paper is to survey decision-making procedures aimed for sustainable renovation. We inventory existi
