One way of reducing environmental pollution is to reduce our dependence on fossil fuels by replacing them with solar radiation (Rs), which is one of the main sources of clean and renewable energy. In this study, daily Rs values at seven meteorological stations in Iran (Ahvaz, Isfahan, Kermanshah, Mashhad, Bandar Abbas, Kerman and Tabriz) over 2010-2019 were estimated using empirical models, suppor

Energy-efficient selective physisorption driven C2H2 separation from industrial C2-C1 impurities such as C2H4, CO2 and CH4 is of great importance in the purification of downstream commodity chemicals. We address this challenge employing a series of isoreticular cationic metal-organic frameworks, namely iMOF-nC (n=5, 6, 7). All three square lattice topology MOFs registered higher C2H2 uptakes versu

Soil microbial communities perform vital ecosystem functions, such as the decomposition of organic matter to provide plant nutrition. However, despite the functional importance of soil microorganisms, attribution of ecosystem function to particular constituents of the microbial community has been impeded by a lack of information linking microbial function to community composition and structure. He

Research on telomeres in the fields of ecology and evolution has been rapidly expanding over the last two decades. This has resulted in the formulation of a multitude of, often name-given, hypotheses related to the associations between telomeres and life-history traits or fitness-facilitating processes (and the mechanisms underlying them). However, the differences (or similarities) between the var

Orangelavar, släktet Caloplaca i vid bemärklelse, är erkänt svåra och många. Dessutom har släktet delats upp i en mängd olika släkten vilket gör det än mer förvirrande. Ovanpå det beskrivs nya arter på löpande band. Här ges dock en översikt av de arter i släktet Blastenia som förekommer i Norden.

Dietary fiber is considered a strong intestinal protector, but we do not know whether dietary fiber protects against the long-lasting mucosal damage caused by ionizing radiation. To evaluate whether a fiber-rich diet can ameliorate the long-lasting pathophysiological hallmarks of the irradiated mucosa, C57BL/6J mice on a fiber-rich bioprocessed oat bran diet or a fiber-free diet received 32 Gray i

Syftet med denna uppsats är att undersöka vad som händer när en ny musikpedagogisk idé/metod införs och etableras i ett sammanhang där det redan finns en dominerande metod. Undersökningen består utav en kvalitativ forskningsstudie med djupintervjuer av två danska Suzuki teacher trainers och med en narrativ analysmetod som verktyg. Den teoretiska utgångspunkten är ett sociokulturellt perspektiv ochThe aim of this study is to scrutinize what happens when a new music pedagogical approach is introduced in a context already dominated by another method. This is a qualitative research study using a narrative analysis method on two in depth interviews with two Danish Suzuki teacher trainers. The theoretical point of view is a sociocultural perspective and mainly cultural-historical activity theory

Attosecond transient absorption spectroscopy (ATAS) allows for the study of electron dynamics in atoms and molecules with attosecond time resolution. Previous works reported in the literature have made use of ATAS to image and control such dynamics in the single-channel ionization continuum of helium; in particular, in the vicinity of the doubly excited autoionizing states lying between the N=1and

En presentation av mitt avhandlingsprojekt.

Syftet med denna studie är att analysera hur musikutbildningsprogrammet El Sistema vid Malmö Kulturskola beskrivs i media och officiella dokument (2011–2017). Detta görs genom en ideologikritisk dokumentanalys och med kritisk realism som teoretiskt ramverk. Resultatet visar att El Sistema beskrivs som en riktad politisk insats med aspirationer på att vara ett integrationsprojekt, verksamt i mångku

The purpose of the study is to explore how a multinational enterprise can use social innovations to drive change and solve grand challenges in an emerging market context. This paper brings market-shaping literature into a sustainability context, particularly by studying the implementation of social innovations in an emerging market context. Specifically, the study involves an in-depth qualitative

We have determined spectral phases of Ne autoionizing states from extreme ultraviolet and midinfrared attosecond interferometric measurements and ab initio full-electron time-dependent theoretical calculations in an energy interval where several of these states are coherently populated. The retrieved phases exhibit a complex behavior as a function of photon energy, which is the consequence of the

This paper applies the peridynamic continuum mechanics theory on a new type of material known as harmonic-structured materials. Using the Peridigm software, rapid uniaxial elongation is simulated on a peridynamic model of a thin bimodal harmonic-structured metal sheet. Mechanical wave initiation, propagation, and reflection, as well as fracture initiation and propagation are successfully simulated

When producing intimidating aggressive vocalizations, humans and other animals often extend their vocal tracts to lower their voice resonance frequencies (formants) and thus sound big. Is acoustic size exaggeration more effective when the vocal tract is extended before, or during, the vocalization, and how do listeners interpret within-call changes in apparent vocal tract length? We compared perce

PURPOSE: To investigate the acute exercise effects of dynamic standing exercise on blood glucose and blood lactate among children and adolescents with cerebral palsy who are nonambulant.METHODS: Twenty-four participants with cerebral palsy who are nonambulant performed 30 minutes of dynamic standing exercise using a motorized device enabling assisted passive movements in an upright weight-bearing

Purpose: To describe the use of assistive devices and postural asymmetries in lying, sitting and standing positions in adults with cerebral palsy, and to analyze postural asymmetries and any associations with their ability to maintain or change position and time in these positions. Methods: A cross-sectional study based on data from the Swedish Cerebral Palsy follow-up program of 1,547 adults aged

PET-CT är baserad på positronemissionstomografi kombinerat med datortomografi. Före en PET-CT-undersökning injiceras ett radioaktivt spårämne (även kallat radiofarmaka) intravenöst i patienten. PET avbildar fördelningen av detta spårämne genom att detektera dess sönderfall. Under de senaste åren har PET-tekniken utvecklats och förbättrats inom hårdvara och mjukvara. Dessutom har nya radioaktiva spThe PET-CT imaging modality is based on positron emission tomography combined with computed tomography. Before a PET-CT examination, a radioactive tracer (also called a radiopharmaceutical) is intravenously injected into the patient. PET technology images the distribution of this tracer element by detecting the decay. In recent years, PET technology has been developed and improved in hardware and

We establish quantitative results for the statistical behaviour of infinite systems. We consider two kinds of infinite system: i) a conservative dynamical system (f, X, µ) preserving a σ-finite measure µ such that µ(X) = ∞; ii) the case where µ is a probability measure but we consider the statistical behaviour of an observable φ: X → [0, ∞) which is non-integrable: R φ dµ = ∞.
