Oxy-fuel combustion is one of the proposed technologies with the potential to achieve zero CO2 emission. La1−xCaxCo1−yFeyO3−δ (LCCF) perovskites are promising materials with high selectively for oxygen. In this study, the oxygen non-stoichiometry of perovskites LCCF was investigated by means of iodometric titration. LCCF was prepared using the liquid citrate method, and the phase structures were i

Boreal forests are important for climate regulation since they store anthropogenic carbon emissions in vegetation as well as in soil. Forests fires might counterbalance this by releasing the stored carbon to the atmosphere. In this review the effect of forest fires on carbon dynamics in boreal forests was examined. More specifically, studies were reviewed estimating the combustion emissions of car

På Siciliens östkust strax söder om Syrakusa, ligger ett långsmalt naturområde som följer kusten längs halvön Maddalenas sydspets ut till udden Capo Murro di Porco. Det är en obebyggd kustremsa sånär som på en fyrbyggnad med två angränsande stenhus. Naturen domineras av det klippiga landskapet och de tre byggnaderna som kommit att smälta in i omgivningen. I detta arbete, som är en fallstudie som Capo Murro di Porco is situated in a narrow natural area that runs along the coast of the peninsula of Maddalena, just south of Syracuse on the east coast of Sicily. It is an area of stunning nature with dramatic topography, steep cliff sides and sparse vegetation. On the very line marking the transition from low vegetation to bare rock on the horn of the peninsula, a lighthouse and two rugged low

The isopropanol-soluble seed storage proteins, prolamins, were studied in 18 different genera of the tribe Triticeae by gel electrophoresis, Coomassie staining, and immunoblot assays. The monoclonal antibodies were originally raised against cultivated barley (Hordeum vulgare L.) hordein, and their reactions had been tested earlier on wild Hordeum species. The study showed that all the investigated

This is the second annual report for the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010. The programme is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sciences and the Swedi

The specific binding of [3H]α-dihydropicrotoxinin to rat brain membranes was inhibited competitively and potently (IC50 ≅ 100 nM) by a convulsant benzodiazepine drug, RO5-3663. This compound did not inhibit high affinity flunitrazepam binding to the same tissue under similar conditions, and its reported pharmacological activity as an antagonist of GABAergic synaptic transmission, which resembles t

Telomerase maintains telomere length and chromosome integrity by adding short tandem repeats of single-stranded DNA to the 3' ends, via reverse transcription of a defined template region of its RNA subunit. To further understand the telomerase elongation mechanism, we studied the primer utilization and extension activity of the telomerase from the budding yeast Naumovozyma castellii (Saccharomyces

Metal closo-boranes have recently received significant attention as solid-state electrolytes due to their high thermal and electrochemical stability, and the weak interaction between the cat- and anion, facilitating fast ionic conductivity. Here we report a synthesis method for obtaining a novel mixed closo-carborane compound, [NH(CH3)3][(CB8H9)0.26(CB9H10)0.66(CB11H12)0.08]. The crystal structure

The Aquatic Warbler Acrocephalus paludicola is a globally threatened, long-distance migratory passerine that continues to decline in abundance and range. Studies throughout its annual cycle are needed, including during migration, when information on habitat availability and usage are important for conservation. Here, the autumn occurrence (distribution, abundance, phenology) of Aquatic Warblers in

The study of psychosocial is highly relevant for project-based sector like construction owing to the following justifications: mobility of workers, constant change of workplace, diversity of work performed, physically demanding, high health and safety risk, meeting deadlines, monetary constraints and male-dominated industry. All these factors contribute to the industry having unique and different
