Exposure to UV light triggers the rapid generation and accumulation of reactive oxygen species (ROS) in skin cells, with consequent increase in oxidative stress and thus in photoaging. Exogenous supplementation with dietary antioxidants and/or skin pretreatment with antioxidant-based lotions before sun exposure might be a winning strategy against age-related skin pathologies. In this context, plan
Membrane fouling and its control is one of the most critical parameters in the application of membrane processes. The degree of fouling depends on the application and on industrial scale, fouling is often observed as reduction in plant capacity over time. One approach to reduce fouling for the pressure driven processes microfiltration and ultrafiltration is to use hydrophilic membranes. This paper
The recent developments in the field of biorefineries open new opportunities for the pulp and paper industry to diverse from classical carton and paper production to bio-based chemicals. The trend is thus to use the three key wood components hemicelluloses, lignin and cellulose as raw materials for production of a wide range of biochemicals. A key success factor is the integration of energy-effici
Despite strong scientific evidence supporting the benefits of regular exercise for the prevention and management of cardiovascular disease (CVD), physical inactivity is highly prevalent worldwide. In addition to merely changing well-known risk factors for systemic CVD, regular exercise can also improve cardiovascular health through non-traditional mechanisms. Understanding the pathways through whi
In recent years biorefineries using lignocellulosic biomass such as wood and agricultural residuals as raw material have gained significant interest since they avoid competition with food production. One of the key development areas of these lignocellulosic based biorefinery concepts is the integration low energy and high selective separation processes. Thus, membrane processes either as stand-a
1. IntroductionThe third wave of biotechnology – white biotechnology – started with the end of the 20th century with the goal to replace conventional chemical processes based on C2/C3 chemistry by biotechnological processes. In biotechnology fermentation is used as standard conversion process for the production of bulk fermentation products such as antibiotics, enzymes, bioethanol and organic acid
Background: Improvement in the surgical system requires intersectoral coordination. To achieve this, the development of National Surgical, Obstetric, and Anaesthesia Plans (NSOAPS) has been recommended. One of the first steps of NSOAP development is situational analysis. On the ground situational analyses can be resource intensive and often duplicative. In 2016, the Ministry of Health of Tanzania
Observational learning is a successful method for improving writing skills in various genres. We explore effects of a five lesson intervention series based on peer observation. Fifty-five Swedish 5th-grade students aged 10-12 years followed this intervention program. The language and reading comprehension and working memory capacity were tested. The students watched short film-clips with peers wor
Mutations in NPM1 can be used for minimal residual disease (MRD) analysis in acute myeloid leukemia (AML). We here applied a newly introduced method, deep sequencing, allowing for simultaneous analysis of all recurrent NPM1 insertions and thus constituting an attractive alternative to multiple PCRs for the clinical laboratory. We retrospectively used deep sequencing for measurement of MRD pre- and
The EMS Summer School “Membranes in Biorefineries” is related to Annex XVII of the Industrial Energy Related Technologies and Systems (IETS)Implementing Agreement: “Membrane Filtration for Energy-efficient Separation of Lignocellulosic Biomass Components” co-ordinated by the Department of Chemical Engineering at Lund University, Sweden.The IETS Implementing Agreement is an initiative within IEA (I
Based on trend, cross-cutting relationships and U-Pb dating, Precambrian mafic dykes in the Singhbhum craton, earlier collectively identified as ‘Newer Dolerite Swarm’ have been separated into seven distinct swarms, which are thought to be the plumbing systems for Large Igneous Provinces (LIPs). These Singhbhum swarms range in age from ∼2.80 Ga to ∼1.76 Ga, and include the ∼2.80 Ga NE-SW trending
Aims and objectives: To study practice in consciousness assessment among neuroscience nurses in Europe. Background: Over the years, several instruments have been developed to assess the level of consciousness for patients with brain injury. It is unclear which instrument is being used by nurses in Europe and how they are trained to use these tools adequately. Design/methods: A cross-sectional ques
The recent upsurge of interest in the experimental city as an arena within and through which urban sustainability is governed marks not only the emergence of the proliferation of forms of experimentation – from novel governance arrangements to demonstration projects, transition management processes to grassroots innovations – but also an increasing sensibility amongst the research community that u
In astrophysics, the ‘Goldilocks Zone’ describes the circumstellar habitable zone, in which planets, sufficiently similar to Earth, could support human life. The children’s story of Goldilocks and the Three Bears, one of the most popular fairy tales in the English language, uses this metaphor to describe conditions for life that are neither too hot nor too cold and neither too close to the sun nor
This study examined health-related quality of life of youth in secure residential care employing a gender perspective. The KIDSCREEN-52 questionnaire was administered to 91 youths (46 boys and 45 girls) aged 13–17, admitted to four secure residential units in southern Sweden, in connection with a medical examination. Results were compared with a national Swedish survey from 2009 of 86,000 youths a
WD 1145+017 is currently the only white dwarf known to exhibit periodic transits of planetary debris as well as absorption lines from circumstellar gas. We present the first simultaneous fast optical spectrophotometry and broad-band photometry of the system, obtained with the Gran Telescopio Canarias (GTC) and the Liverpool Telescope, respectively. The observations spanned 5.5 h, somewhat longer t
