The glycaemic index: importance of dietary fibre and other food properties

An increasing body of evidence suggests that a low-glycaemic-index (GI) diet has a therapeutic as well as a preventive potential in relation to the insulin resistance syndrome. The implementation of a low-GI diet, however, will require an extended list of low-GI foods to be available on the market. The tailoring of low-GI bread products offers a particular challenge due to their generally high GI

The ultimate outcome of black hole - neutron star mergers

We present a simple, semi--analytical description for the final stagesof mergers of black hole (BH) -- neutron star (NS) systems. Such systemsare of much interest as gravitational wave sources and gamma--ray burstprogenitors. Numerical studies show that in general the neutron star isnot disrupted at the first phase of mass transfer. Instead, what remainsof the neutron star is left on a wider, ecce

Correlated dynamics of consecutive residues reveal transient and cooperative unfolding of secondary structure in proteins

Nuclear spin relaxation is a powerful method for studying molecular dynamics at atomic resolution. Recent methods development in biomolecular NMR spectroscopy has enabled detailed investigations of molecular dynamics that are critical for biological function, with prominent examples addressing allostery, enzyme catalysis, and protein folding. Dynamic processes with similar correlation times are of

Diversity and phylogeny of mitochondrial cytochrome b lineages from six morphological species of avian Haemoproteus

Species of Haemoproteus (Haemosporida: Haemoproteidae), avian haemosporidians, have traditionally been described based on morphology of their gametocytes and on limited experimental information on their vertebrate host specificity. We investigated to what extent the morphological species are represented by monophyletic groups based on DNA sequence data using 2 different fragment lengths of the cyt

Musikaliska ledare i stämman : Körforskning med olika metoder

I antologin är kapitel samlade som ut olika perspektiv behandlar undervisning och lärande i musik samt musiklärares professionsutveckling. Karl Asp problematiserar genrebegreppet och exemplifierar hur det är möjligt att planera sin musikundervisning utifrån resonemang om vad genre kan tänkas vara och innebära. Konsekvenser av genrer och de praktiker som kan uppstå i ensembleundervisning när det gä

Biochar from cookstoves reduces greenhouse gas emissions from smallholder farms in Africa

Biochar produced in cookstoves has the potential to contribute to negative carbon emissions through sequestration of biomass carbon while also providing other benefits for sustainable development, including provision of clean renewable energy and increased yields in tropical agriculture. The aim of the reported research was to estimate effects on food production, household energy access and life c

Controlling photoionization using attosecond time-slit interferences

When small quantum systems, atoms or molecules, absorb a high-energy photon, electrons are emitted with a well-defined energy and a highly symmetric angular distribution, ruled by energy quantization and parity conservation. These rules are based on approximations and symmetries which may break down when atoms are exposed to ultrashort and intense optical pulses. This raises the question of their

Pressurized DNA state inside herpes capsids-A novel antiviral target

Drug resistance in viruses represents one of the major challenges of healthcare. As part of an effort to provide a treatment that avoids the possibility of drug resistance, we discovered a novel mechanism of action (MOA) and specific compounds to treat all nine human herpesviruses and animal herpesviruses. The novel MOA targets the pressurized genome state in a viral capsid, "turns off" capsid pre

Making massive stars in the Galactic Centre via accretion on to low-mass stars within an accretion disc

The origin of the population of very massive stars observed within ∼0.4 pc of the supermassive black hole in the Galactic Centre is a mystery. Tidal forces from the black hole would likely inhibit in situ star formation whilst the youth of the massive stars would seem to exclude formation elsewhere followed by transportation (somehow) into the Galactic Centre. Here, we consider a third way to prod

The role of wingbeat frequency and amplitude in flight power

Body-mounted accelerometers provide a new prospect for estimating power use in flying birds, as the signal varies with the two major kinematic determinants of aerodynamic power: wingbeat frequency and amplitude. Yet wingbeat frequency is sometimes used as a proxy for power output in isolation. There is, therefore, a need to understand which kinematic parameter birds vary and whether this is predic
