COVID-19 weakens both sides in the battle between coal and renewables

By disrupting investment, supply chains and technology diffusion, COVID-19 may harm renewables more than coal, but still weaken coal lock-in in developing countries. To enable new low-carbon energy choices, international flows of low-carbon technology and policy expertise must quickly re-emerge.

Muconic Acid Production Using Engineered Pseudomonas putida KT2440 and a Guaiacol-Rich Fraction Derived from Kraft Lignin

Industrial lignin such as kraft lignin is an abundant feedstock for renewable chemicals and materials. In this study, a process was developed for depolymerization of kraft lignin followed by an upgrading separation step and further bioconversion of the obtained monoaromatic compounds to muconic acid. First, industrial kraft lignin, Indulin AT, was processed into a guaiacol-rich stream using base-c

Innovation in the long run: Perspectives on technological transitions in Sweden 1908-2016

There are fundamental unresolved questions about the nature of the long-run interplay between innovation and economic development processes. This study examines technological transitions in Sweden, 1908-2016, using a new literature-based innovation output indicator for the engineering industry, allowing a mixed-methods approach. The results suggest that waves of innovation have taken place during

Experimental wildfire induced mobility of radiocesium in a boreal forest environment

Wildfires are expected to increase with warmer climate, which can contribute to the mobility and the resuspension of long-lived and potentially hazardous radionuclides. The release of 137Cs during combustion of dried litter, forest floor organic soil, and peat was investigated in a small-scale experimental set-up. Combustion conditions were varied to simulate different wildfire scenarios, and the

Region-specific radioecological evaluation of accidental releases of radionuclides from ESS

Gadolinium-148 is one of the radionuclides of most concern that will be produced in the tungsten target of the European Spallation Source (ESS), as a by-product of the spallation reaction used by the facility to produce neutrons. Since 148Gd a pure alpha emitter, it is both very radiotoxic and difficult to measure. With its half-life of 75 years, it will remain in the environment for a long time i

Variability in end-of-life healthcare use in patients with osteoarthritis : a population-based matched cohort study

PURPOSE: To investigate the patterns of healthcare use (HCU) at the last year of life in persons with osteoarthritis (OA).METHODS: Using linked registers, we identified persons aged≥ 65 years who died during 2003-2014 and were resided in the Skåne region during 5-year prior to death. Among these, we randomly matched decedents with a principal OA diagnosis prior to the last year of life (OA cohort,

Local Contexts of Interpreting a Cold War Relationship : Pommersche Landeskirche and Växjö Diocese, 1975–1989

This article explores how an East-west inter-church relationship during the Cold War was given multiple meanings. The link that emerged during the late 1970s between Växjö diocese (Church of Sweden) and Pommersche Landeskirche is used to illustrate the case in point. Whereas an Uppsala-based national church leadership saw such connections as efforts to bring peace and reconciliation, the regional

Resonance in dialogue : The interplay between intersubjective motivations and cognitive facilitation

Dialogic resonance, when speakers reproduce constructions from prior turns, is a compelling type of coordination in everyday conversation. This study takes its starting point in resonance in stance-taking sequences with the aim to account for the interplay between intersubjective motivations and cognitive facilitation in resonance production. It analyzes stance-taking sequences in the London–Lund

Lignin-Inspired Polymers with High Glass Transition Temperature and Solvent Resistance from 4-Hydroxybenzonitrile, Vanillonitrile, and Syringonitrile Methacrylates

We here report on the synthesis and polymerization of nitrile-containing methacrylate monomers, prepared via straightforward nitrilation of the corresponding lignin-inspired aldehyde. The polymethacrylates reached exceptionally high glass transition temperatures (Tg values), i.e., 150, 164, and 238 °C for the 4-hydroxybenzonitrile, vanillonitrile, and syringonitrile derivatives, respectively,

The more the merrier? : Examining the relationship between emotional expressions and user engagement on Swedish nonprofits’ Facebook pages, 2014-2019

Organizations interact with their stakeholders to a large degree through social media such as Facebook, Instagram, Twitter and YouTube ( Bellucci & Manetti, 2017). There are indications that there is an increase in the use of emotional language in organizations’ external communication in social media over time, since this is thought to generate more stakeholder engagement (Weinryb et al, 2021)

Dose-length-product determination on cone beam computed tomography through experimental measurements and dose-area-product conversion

The dosimetry of cone beam computed tomography (CBCT) is not fully elaborated yet, and some of these systems presents dose-area-product (DAP) values after an examination rather than, as in the case of traditional CT, the doselength- product (DLP). The purpose of this study was to provide a reproducible and straight-forward method for DLP measurements on CBCT, as well as to validate a tool for estiThe dosimetry of cone beam computed tomography (CBCT) is not fully elaborated yet, and some of these systems presents dose-area-product (DAP) values after an examination rather than, as in the case of traditional CT, the doselength- product (DLP).

Urban neighborhoods – the locus of change. What can we learn from the transition story of Augustenborg?

Cities, and more importantly urban neighborhoods, are key sites of infrastructure provision with direct links to social and environmental concerns. They are increasingly seen as sites of strategic action in transitions toward sustainability and resilience, and offer big opportunities for fundamental societal change. The framing of neighborhood-level problems and their solutions, governance process

Detection of Perfusion Deficits in Multiphase Computed Tomography Angiography—A Stroke Imaging Technique Based on Iodine Mapping on Spectral Computed Tomography: Initial Findings

Objective: The purpose of this study was to explore a novel method forbrain tissue differentiation using quantitative analysis of multiphase computedtomography (CT) angiography (MP-CTA) on spectral CT, to assesswhether it can distinguish underperfused fromnormal tissue, using CT perfusion(CTP) as reference.Methods: Noncontrast CT and MP-CTA images from 10 patients wereanalyzed in vascular regions

Effects of crop and non-crop resources and competition : High importance of trees and oilseed rape for solitary bee reproduction

To mitigate wild bee declines, it is important to understand the separate and joint effects of parallel losses of semi-natural habitats containing flower resources and increases in transient flower resources provided by mass-flowering crops. Since mobility may affect how bee species cope with these changes, they may also affect competitive interactions and thus community composition. We focused onTo mitigate wild bee declines, it is important to understand the separate and joint effects of parallel losses of semi-natural habitats containing flower resources and increases in transient flower resources provided by mass- flowering crops.

High dependency of chilli fruit set on wild pollinators in southern India

Ongoing pollinator declines threaten the production of many entomophilous crops. Recent reports that yields of animal-pollinated crops in India are increasing less than pollinator-independent ones suggest the occurrence of pollen limitation. We experimentally evaluated if production of the common food crop chilli benefits from insect pollination and if crop production is constrained by lack of pol
