The Australian lycaenid butterfly Jalmenus evagoras has iridescent wings that are sexually dimorphic, spectrally and in their degree of polarization, suggesting that these properties are likely to be important in mate recognition. We first describe the results of a field experiment showing that free-flying individuals of J. evagoras discriminate between visual stimuli that vary in polarization con

The structural properties of the hexagonal multiferroic h-HoMnO3 under high pressure have been explored using synchrotron x-ray diffraction and x-ray absorption spectroscopy in diamond anvil cells. The structure was found to undergo a pressure-induced phase transition at ∼24 GPa to a rhombohedrally distorted superstructure, which is isostructural to the oxygen-loaded h-RMnO3+δ (R=Y,Dy,Ho,Er; δ≈0.2

In the last decade, with the growing demand for efficient and more sustainable products that reduce our CO2 footprint, progresses in Additive Manufacturing (AM) have paved the way for optimized heat exchangers, whose disruptive design will heavily depend on predictive numerical simulations. Typical AM rough surfaces show limited resemblance to the artificially constructed rough surfaces that have

Numerous studies have demonstrated the normal tissue-sparing effects of ultra-high dose rate ‘FLASH’ irradiation in vivo, with an associated reduction in damage burden being reported in vitro. Towards this, two key radiochemical mechanisms have been proposed: radical–radical recombination (RRR) and transient oxygen depletion (TOD), with both being proposed to lead to reduced levels of induced dama

Strong sexual selection frequently leads to sexual conflict and ensuing male harm, whereby males increase their reproductive success at the expense of harming females. Male harm is a widespread evolutionary phenomenon with a strong bearing on population viability. Thus, understanding how it unfolds in the wild is a current priority. Here, we sampled a wild Drosophila melanogaster population and st

Abstract: Specific features of the pyridine structure make it a convenient model system to describe coal combustion; however, the main attention of researchers has been paid to the formation of the ortho-pyridyl, whereas the formation of meta- and para-pyridyls has been yet poorly studied. The rate constants of the formation of three pyridyl radicals originating from pyridine by hydrogen atom abst

Context. Elemental abundances can be determined from stellar spectra, making it possible to study galactic formation and evolution. Accurate atomic data is essential for the reliable interpretation and modeling of astrophysical spectra. In this work, we perform laboratory studies on neutral aluminium. This element is found, for example, in young, massive stars and it is a key element for tracing o

The canihua (Chenopodium pallidicaule) is a native Andean crop that stands out for its high content of protein, fiber, and minerals and that has a good fatty acid profile. We studied six canihuas cultivars, which were compared according to their proximate, mineral, and fatty acid composition. Based on the form of stems, termed growth habit, they belonged to two groups: decumbent (Lasta Rosada, Ill

The Boltzmann–Gibbs additive entropy (Formula presented.) and associated statistical mechanics were generalized in 1988 into nonadditive entropy (Formula presented.) and nonextensive statistical mechanics, respectively. Since then, a plethora of medical applications have emerged. In the present review, we illustrate them by briefly presenting image and signal processings, tissue radiation response

Evidence of the effectiveness of the tests used to diagnose Helicobacter pylori (H. pylori) in primary healthcare is limited. This cross-sectional study aims to assess the accuracy of tests used for to diagnose H. pylori infection in primary care patients and its relationship with gastroduodenal pathologies. Over 12 months, 173 primary care patients with dyspeptic symptoms were referred for upper

Making It Home: An Aesthetic Methodological Contribution to the Study of Migrant Home-Making and Politics of Integration (aka MaHoMe) is a NordForsk-funded project involving eight researchers from universities in the UK, Denmark and Sweden. It examines how migrants make and make sense of home amidst the complex and divergent politics of integration in these three so-called “host societies”. My rol

What role has music played in global colonial projects? And how has musical colonisation been implemented on a large scale? To address these questions, I analyse the work of the evangelical missionary administrators Christian Ignatius Latrobe (1756–1836) and Hans-Peter Hallbeck (1784–1840). Latrobe was a London-based music historian, composer and editor who oversaw the missionary work of the Morav

A network mechanics model for analysis of materials made of dry-shaped cellulose fibres is proposed. In terms of the model, the network is composed of fibres of arbitrary distribution in length, curvature, cross-section. stiffness and strength. The fibres are arranged in a random structure according to an arbitrary orientation distribution. Where fibres meet there may be fibre-to-fibre interaction

The introduction of laminated timber, glulam being an example, allowed many of the disadvantages associated with solid wood to be overcome. The disadvantages in question are mainly those related to the size and shape limits of structural elements made of solid wood and to the large variability in such material properties of solid wood as strength and stiffness.In the present thesis, which comprise
