Solid oxide fuel cells (SOFCs) directly convert chemical energy to electricity with high electrical efficiency. It involves gas transport through the porous electrode to the three-phase boundaries (TPB). The tortuosity of gas transport relates the bulk diffusion of gas in free space to the effective diffusion coefficient of gas migrating through a porous material. Therefore, determining the tortuo
The industrialization of agriculture and efforts to maximize yields of commodity crops are major drivers of biodiversity loss and disruption of ecosystems balance. To become more sustainable, agriculture needs to be aligned with the delivery of multiple ecosystem services, and reduce its dependency on external inputs and its negative environmental impacts. Increasing crop diversity may be a key st
This paper treats the problem of control signal saturation caused by feedforward control from measurable load disturbances. An efficient feedforward compensator will often give significant peaks in the control signal at fast changes in the load disturbance. These peaks may cause the control signal to reach a saturation limit. In the paper, it is shown that the anti-windup function may cause unnece
Languages vary considerably in how they group objects into categories. For example, the word taza in Spanish can refer to either cup or mug in English, whereas glass can refer to either copa or vaso – two different types of glasses –, in Spanish. It is still debated whether such language distinctions cause differences in early perceptual processing between speakers of different languages. Here, fo
Aims: An observational nationwide all-comers prospective register study to analyse outcomes after coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in unprotected left main coronary artery (LMCA) disease. Methods and results: All patients undergoing coronary angiography in Sweden are registered in the Swedish Web-system for Enhancement and Development of Evidence-b
Det övergripande syftet med denna studie, som ingick i forskningsprojektet Skånska hem: mottagande, etablering eller exkludering – hemlöshetspolitik och strategier för flyktingars bosättning, var att undersöka och beskriva Svalövs kommuns strategier för mottagande och bosättning av flyktingar och hemlösa kommuninvånare under åren 2018 till och med 2022. Forskningsprojektet ska ses mot bakgrund av
COVID-19 was first identified in Wuhan City in December 2019 and spread throughout Hubei Province and other parts of China. After causing significant morbidity and mortality in China, by February 2020, it had spread to numerous other countries, infecting millions of people and causing a large number of deaths across the world. The COVID-19 pandemic put a burden on almost all areas of the world inc
Distinct tissue-specific mechanisms mediate insulin action in fasting and postprandial states. Previous genetic studies have largely focused on insulin resistance in the fasting state, where hepatic insulin action dominates. Here we studied genetic variants influencing insulin levels measured 2 h after a glucose challenge in >55,000 participants from three ancestry groups. We identified ten new lo
This communication describes a two unit antisense RNA cassette system for use in gene silencing. Cassettes consist of a recognition unit and an inhibitory unit which are transcribed into a single RNA that carries sequences of non-contiguous complementarity to the chosen target RNA. The recognition unit is designed as a stem-loop for rapid formation of long- lived binding intermediates with target
Background: Joint pain and chronic back pain are highly prevalent in the aging population and have a large impact on life quality. As the underlying mechanisms are not fully understood, this exploratory cross-sectional study aimed to discover proteins and pathways associated with these two pain conditions in Swedish 70-year-old men. Methods: Plasma proteins (n = 720) were measured in participants
Populations are presumed to be adapted to local environmental conditions via natural selection, with gene flow breaking up local adaptations. In birds, various aspects of feathers may reflect local adaptation. For example, the insulation capacity of feathers could be greater in colder regions, while colour variation may also play a role in adapting to local environmental conditions since darker fe
This paper explores an initiative by a local government in Rättvik, Sweden, to increase the consumption of local food in the municipal kitchens. It explores public procurement of local food as a way for local governments to address sustainability and climate goals while meeting residents’ demand for ‘good’ local food. Through a qualitative case study reviewing food and procurement policies across
Introduction.Kraft black liquor is a side-stream produced during the kraft pulping process containing lignin, hemicelluloses and cooking chemicals. The stream is usually evaporated and burned in the recovery boiler to recover the cooking chemicals and generate energy. The mill is, however, often/sometimes limited by recovery boiler capacity, and removing some of the lignin from kraft black liquor
Membrane technology has proven successful for separating, concentrating, and purifying compounds from streams in the pulp and paper industry. A key stream is kraft black liquor (KBL) from which lignin can be recovered by nanofiltration (NF). However, membrane technology has not yet been implemented on large scale for this process. One reason is the lack of efficientunderstanding of membrane cleani
