Wild-caught great tits Parus major fail to use tools in a laboratory experiment, despite facilitation

Studies investigating tool use in animals that are not known tool users in the wild are important in helping to understand how and under what circumstances this ability might arise. Tool use appears to be uncommon in great tits (Parus major), with only a single documented observation in which a wild great tit used conifer needles to extract larvae from crevices in trees. In a laboratory-based expe

What future for primates? Conservation struggles in the forests of Cross River State, Nigeria

While deforestation and forest degradation have gained attention in recent years not least at the UN climate negotiations, a third “de”, i.e., defaunation, has to a great extent been overlooked. Human-induced faunal loss does not only reduce tree species diversity, but also significantly erodes key ecosystem services and functions and further disadvantages local communities. In this article, we an

The Preparation of Decellularized Mouse Lung Matrix Scaffolds for Analysis of Lung Regenerative Cell Potential

Lung transplantation is the only option for patients with end-stage lung disease, but there is a shortage of available lung donors. Furthermore, efficiency of lung transplantation has been limited due to primary graft dysfunction. Recent mouse models mimicking lung disease in humans have allowed for deepening our understanding of disease pathomechanisms. Moreover, new techniques such as decellular

Computed electronic and optical properties of SnO2 under compressive stress

We consider the effects of three different types of applied compressive stress on the structural, electronic and optical properties of rutile SnO2. We use standard density functional theory (DFT) to determine the structural parameters. The effective masses and the electronic band gap, as well as their stress derivatives, are computed within both DFT and many-body perturbation theory (MBPT). The st

10Be and Cosmogenic Radionuclides in Ice Cores

This article summarizes the processes that are responsible for cosmogenic radionuclide variations in ice cores and the results that can be inferred from these records. The article starts with the production in the atmosphere caused by the influx of galactic cosmic ray particles and its modulation by the solar and geomagnetic fields. Subsequently, the geochemical behavior of cosmogenic radionuclide

Quasiparticle electronic structure of barium-silicon oxynitrides for white-LED application

Ba3Si6O12N2:Eu2+ and Ba3Si6O9N4:Eu2+ have strikingly similar atomistic structures, but the former is an efficient green phosphor at working temperature while the latter is a bluish-green phosphor whose luminescence decreases quite fast with temperature. Aiming at the understanding of such different behavior, we compute the quasiparticle electronic band structure of the two hosts, Ba3Si6O 12N2 and

Band widths and gaps from the Tran-Blaha functional : Comparison with many-body perturbation theory

For a set of ten crystalline materials (oxides and semiconductors), we compute the electronic band structures using the Tran-Blaha (TB09) functional. The band widths and gaps are compared with those from the local-density approximation (LDA) functional, many-body perturbation theory (MBPT), and experiments. At the density-functional theory (DFT) level, TB09 leads to band gaps in much better agreem

Climate-fire interactions and Savanna ecosystems : A dynamic vegetation modeling study for the African Continent

Savannas are inherently “disturbed” ecosystems, but the regularly recurring disruptions play such a fundamental ecological role (Scholes and Archer, 1997) that “episodic events” rather than “disturbance” may the more apt terminology. From an atmospheric perspective, fire is the most significant of these episodic events. Fires shape community species composition; tree to grass ratio and nutrient re

Electronic properties of interfaces and defects from many-body perturbation theory : Recent developments and applications

We review some recent developments in many-body perturbation theory (MBPT) calculations that have enabled the study of interfaces and defects. Starting from the theoretical basis of MBPT, Hedin's equations are presented, leading to the GW and GWΓ approximations. We introduce the perturbative approach, that is the one most commonly used for obtaining quasiparticle (QP) energies. The practical strat

G0W0 band gap of ZnO : Effects of plasmon-pole models

Carefully converged calculations are performed for the band gap of ZnO within many-body perturbation theory (G0W0 approximation). The results obtained using four different well-established plasmon-pole models are compared with those of explicit calculations without such models (the contour-deformation approach). This comparison shows that, surprisingly, plasmon-pole models depending on the f-sum r

GW approximations and vertex corrections on the Keldysh time-loop contour : Application for model systems at equilibrium

We study the effects of self-consistency and vertex corrections on different GW-based approximations for model systems of interacting electrons. For dealing with the most general case, we use the Keldysh time-loop contour formalism to evaluate the single-particle Green's functions. We provide the formal extension of Hedin's GW equations for the Green's function in the Keldysh formalism. We show an

Imagetext and ekphrasis as chances of revival in translation studies

Translation Studies has crossed a tumultuous interval of theorization. But has it passed the linguistic limits instituted by a semiotician like Umberto Eco? Wouldn’t be the time to access more courageously the intersemiotic interregnum with its heterogeneous transfer of signs? As it happens in advertising, concrete poetry, tattoos, and stage or filmed version of famous texts? If we have gradually

Episoder 2 : Hörspel

Episoder utspelar sig i en vintrig småstad där gatljus speglar sig i den kalla snön och där människor befinner sig i rörelse; bort från andra och bort från sig själva. handlingen kretasar kring det möjliga och omöjliga i mötet med andra människor, om avgrunden mellan vad en människa är inför andra och vad hon är inför sig själv.Del 2 handlar om suget efter nåt att dricka och om ensamhet och om sjö

DIFFERENT SPATIAL VISUALIZATION TECHNIQUES FOR FIRE PREVENTION IN STOCKHOLM AND GÖTEBORG

The aim with this paper is to examine how different GIS-based visualization methods can be applied and come to practical uses in the emergency service’s fire preventive work. These techniques motivate and facilitate various forms of fire prevention such as selection of areas or neighborhoods, blocks or buildings before home visits, identification and targeting of different risk groups and customiz

Man's Desire to be God

"Man's Desire to be God" is musical suite stretching from blues, rock, jazz to electronic music and classical music. Through particular performance methods in playing, singing, recording and producing the musical elements are blended together in a most mix. The concept and texts starts out from the sect around Charles Manson in the end of the 60s, out from where a story emerges that revolves aroun

ADDRESSING CASCADING CONSEQUENCES FOR CRITICAL INFRASTRUCTURE AND VITAL SOCIETAL FUNCTIONS IN FLOODING EVENTS

Although there have been significant advances in the research field of critical infrastructures and vital societal functions during the last decade, there still exist many challenges in implementing and carrying out studies in practice. One of these challenges is a feasible method for mapping, analysing and visualising the cascading consequences that arise for critical infrastructures and societal

The Cambrian–Ordovician succession at Lanna, Sweden : stratigraphy and depositional environments

A ca 20 m thick succession of upper Furongian (Cambrian Stage 10) through Middle Ordovician (Darriwilian) strata exposed at Lanna, in the province of Närke, south-central Sweden, is described. The upper Furongian is represented by the Alum Shale Formation and reflects an overall shallowing trend that ultimately resulted in emergence above sea level and subaerial conditions. Hence, as in most other
