Combining studies of animal visual systems with exact imaging of their visual environment can get us a step closer to understand how animals see their “Umwelt”. Here, we have combined both methods to better understand how males of the speckled wood butterfly, Pararge aegeria, see the surroundings of their perches. These males are well known to sit and wait for a chance to mate with a passing femal
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
The study explored experiences of stress in children aged 10–12. An inductive qualitative design was used. Ten focus group interviews were conducted with Swedish schoolchildren (n = 42) aged 10–12. The interviews were audio-recorded, transcribed verbatim, and analyzed using qualitative content analysis. The study identified one theme—“Body and mind react”—and three subthemes: (1) Friendships matte
Environmentally friendly tin (Sn)-based metallic halide perovskites suffer from oxidation and morphological issues. Here, we demonstrate the composition engineering of Pb-Sn-alloyed two-dimensional (2D) Ruddlesden-Popper perovskites, (BA)2(MA)3Pb4-xSnxI13, for efficient and stable solar cell applications. Smooth thin films with high surface coverage are readily formed without using any additive ow
This paper applies an analytical method for developing policy strategies to optimize municipal waste management systems (MWMSs) to the case of the Land of Fires (LoF). The LoF is an area of Italy’s Campania region that is characterized by a legacy of authoritarian environmental governance and the improper dumping and burning of waste. In this paper, we employ the fuzzy cognitive maps (FCM) method,
A variety of alkyl and aryl glycosides were investigated as substrates for almond β-glucosidase catalysed synthesis of hexyl-β-D-glycosides in low aqueous hexanol media. The rate-limiting step in the organic media was determined to be the glycosylation of the enzyme. The kinetic constants V max , K
Enzyme catalysis in water-immiscible organic solvents is strongly influenced by the amount of water present in the reaction mixture. Effects of substitution of part of the water by other polar solvents were studied. In an alcoholysis reaction catalyzed by chymotrypsin deposited on celite, it was possible to exchange half of the water by formamide, ethylene glycol or dimethyl sulfoxide with often i
An academic journal is a special place – even more so an online journal. On the one hand, it is surely one of the main stages of professional qualification, presentation and academic discourse, though regulated through its gatekeeping structures of peer review, official invitation, of academic critique and corrections: it represents an open and accessible, yet not unregulated public space in the b
An academic journal is a special place – even more so an online journal. On the one hand, it is surely one of the main stages of professional qualification, presentation and academic discourse, though regulated through its gatekeeping structures of peer review, official invitation, of academic critique and corrections: it represents an open and accessible, yet not unregulated public space in the b
Using an automatic computerized perimeter developed by Heijl & Krakau (1975b) three different perimetric test logics, one simple (I) and two more complicated and time-consuming (II & III) were investigated in practical experiments on healthy normal test subjects and patients and in computer simulated tests. The patients either had a verified diagnosis of glaucoma or glaucoma was suspected.
The number of publications in the field of chemical cross-linking combined with mass spectrometry (XL-MS) to derive constraints for protein three-dimensional structure modeling and to probe protein-protein interactions has increased during the last years. As the technique is now becoming routine for in vitro and in vivo applications in proteomics and structural biology there is a pressing need to
Biological responses to climate change have been widely documented across taxa and regions, but it remains unclear whether species are maintaining a good match between phenotype and environment, i.e. whether observed trait changes are adaptive. Here we reviewed 10,090 abstracts and extracted data from 71 studies reported in 58 relevant publications, to assess quantitatively whether phenotypic trai
A new generation of N-heterocyclic carbene palladium(II) complexes containing vinyl groups in different positions in the backbone of the N-heterocycle have been developed. The fully characterised monomers were copolymerised with divinylbenzene to fabricate robust polymer supported NHC-PdII complexes and these polymers were applied as heterogeneous catalysts in directed C-H halogenation of arenes w
The complex multi-criteria optimisation problems arising in Kidney Exchange Programmes have received considerable attention both in practice and in the scientific literature. Whereas theoretical advancements are well reviewed and synthesised, this is not the case for practice. We present a synthesis of models and methods applied in present European Kidney Exchange Programmes, which is based on det
Objective: In this study, the aim was to compare the performance of four spatiotemporal decomposition algorithms (stICA, stJADE, stSOBI, and sPCA) and parameters for identifying single motor units in human skeletal muscle under voluntary isometric contractions in ultrafast ultrasound image sequences as an extension of a previous study. The performance was quantified using two measures: (1) the sim
Forty-two chapters have been structured according to the toxicities in cancer entities, and the late effects and follow-up proposals have been discussed by European and American authors. Cancer diseases in children, adolescents and young adults are treated within specific treatment protocols and can produce different late effects that will have to be cared for by specific follow-up recommendations
Historiska aktörer är långt ifrån frånvarande i historieforskningen. Varje land och varje tidsepok har sin beskärda del av biografier över framstående vetenskapsmän, intellektuella och utbildningsreformatorer. Trots detta är det inte fel att hävda att de teoretiska strömningar som har satt sin prägel på historiska och sociologiska studier av kunskap sedan 1960-talet har betonat strukturer framför Historical actors are central to the history of knowledge as they are to all historical scholarship. Every country, every era has its biographies of eminent scientists, intellectuals, and educational reformers. Yet the theoretical currents that have left their mark on the historical and sociological study of knowledge since the 1960s have emphasized structures over actors, collectives over individ
