Carbon cycle responses of semi-arid ecosystems to positive asymmetry in rainfall

Recent evidence shows that warm semi-arid ecosystems are playing a disproportionate role in the interannual variability and greening trend of the global carbon cycle given their mean lower productivity when compared with other biomes (Ahlström et al. 2015 Science, 348, 895). Using multiple observations (land-atmosphere fluxes, biomass, streamflow and remotely sensed vegetation cover) and two state

Language and meaning in a multilingual interdisciplinary teaching and learning context

The present study was undertaken in the frame of the research programme Language Use and Individual Learning at the Department of Education at Lund University, using the intentional-expressive dialogue format developed within this programme. The dialogue format was adjusted to study language use and understanding in a multilingual and interdisciplinary higher education context, by including questi

Working with the divides : Two critical axes in development for transformative professional practices

PurposeThe paper aims to provide a conceptual map of how to mediate between sustainability theory and practice in higher education and how disciplinary divides can be bridged. It further looks at issues linked to knowledge views and drivers for institutional change that affect opportunities for whole institution development promoting action preparedness.Design/methodology/approachTaking its point

At the bridging point : tutoring newly arrived students in Sweden

In Sweden, tutoring in the mother tongue is a special support measure primarily intended for newly arrived students to facilitate their transition into the Swedish school system. Tutoring is premised on the collaboration between the class teacher, responsible for subject-related expertise, and the tutor, who contributes with knowledge of the student’s mother tongue and previous context of studies.

The role of the school library : reflections from Sweden

Libraries are critical learning spaces and may play a significant role in intercultural education initiatives, particularly in Sweden where the national curriculum ascribes central functions to libraries for learning activities. Unfortunately, the ways in which teachers and librarians may collaborate to leverage mutual resources is not fully understood. This article uses Pirjo Lahdenperä’s model o

La discussion traite enparticulier les modalités de collaboration avec l’école, les familles, les associations, les centres de loisirs et autres acteursdu quartier, ainsi que les stratégies mises en pla

Role of Chromium and Vanadium in the Atmospheric Oxidation of Sulfur(IV)

Oxidation of HSO3- in aqueous solution has been studied in the presence of vanadium(V), chromium(III) and chromium(VI). Based on spectrophotometric kinetics data and product analysis it is concluded that the autoxidation rate of sulfur(IV) in slightly acidic solution is unaffected by the presence of vanadium(V) and chromium(III). Chromate(VI), on the other hand, oxidizes sulfur(IV) in a direct red

Nyanlända studenters behov av utbildning : Möjligheter och hinder

Refugees arrive in Sweden in connection with wars and repressive conditions in their countries of origin or refuge. Recently, many have come from the Middle East, and Syria in particular. The situation of refugees has a wide range of consequences for education in the host country, including higher education. Validation and admissions procedures involve administrative challenges, and language is an

Equilibria, Kinetics and Mechanism for Complex Formation Between Hydrogen Sulfate/Sulfate and Palladium(II). Hydrolysis of Tetraaquapalladium(II)

Spectrophotometric equilibrium measurements indicate formation of the complexes [Pd(H2O)(3)HSO4](+) and [Pd(H2O)(3)SO4] in the reaction between [Pd(H2O)(4)](2+) and hydrogen sulfate/sulfate in the region: 0.10 less than or equal to [H+] less than or equal to 0.80 M. The stability constants are 0.7 +/- 0.2 and 19 +/- 6 M-1, respectively, at 25 degrees C and 1.00 M ionic strength. The protolysis con

trans-Influence of Triphenyl Stibine. Crystal and Molecular Structures of cis-[PtCl2(SbPh3)2] and trans-[PtI2(SbPh3)2]

Crystals of cis-[PtCl2(SbPh3)(2)] (1) are monoclinic, space group P2(1)/a with a = 20.5708(12), b = 10.1942(4), c = 33.3984(15) Angstrom, beta = 94.394(4)degrees and Z = 8. Substitution of chloride for iodide yields trans-[PtI2(SbPh3)(2)] (2), the crystals of which are monoclinic, space group P2(1)/c with a = 18.108(4), b = 10.102(2), c = 19.1 15(5) Angstrom, beta = 95.241(16)degrees and Z = 4.
