Dietary alpha-ketoglutarate increases cold tolerance in Drosophila melanogaster and enhances protein pool and antioxidant defense in sex-specific manner
Alpha-ketoglutarate (AKG) is an important intermediate in Krebs cycle which bridges the metabolism of amino acids and carbohydrates. Its effects as a dietary supplement on cold tolerance were studied in Drosophila melanogaster Canton S. Two-day-old adult flies fed at larval and adult stages with AKG at moderate concentrations (5-10 mM) recovered faster from chill coma (0 °C for 15 min or 3 h) than
Separation of valence states in thin films with mixed V2O5 and V7O16 phases
Among the other applications, vanadium oxide thin films are considered to be excellent candidates for gas sensing. To understand the origins of the sensing capability, we carried out X-ray photoelectron and X-ray absorption spectroscopy measurements to determinate the surface valence states of thin films with mixed V7O16 and V2O5 compounds. Thin films were fabricated by pulsed laser deposition, an
When the poor excel : Poverty facilitates procedural learning
Recent research has shown that poverty directly impeded cognitive functions because the poor could be easily distracted by monetary concerns. We argue that this effect may be limited to functions relying on working memory. For functions that rely on proceduralized processes however, monetary concerns elicited by reminding of financial demands would be conducive rather than harmful. Our results sup
Conceptual design of the time-of-flight backscattering spectrometer, MIRACLES, at the European Spallation Source
In this work, we present the conceptual design of the backscattering time-of-flight spectrometer MIRACLES approved for construction at the long-pulse European Spallation Source (ESS). MIRACLES's unparalleled combination of variable resolution, high flux, extended energy, and momentum transfer (0.2-6 Å-1) ranges will open new avenues for neutron backscattering spectroscopy. Its remarkable flexibili
Phylogeography of the European rock rose Helianthemum nummularium s.l. (Cistaceae) : western richness and eastern poverty
Helianthemum nummularium s.l. is a young, morphologically diverse species distributed from western Europe to the Caucasus and the Southern Urals in the east. We analysed the rps16-trnK plastid intergenic spacer sequences from 85 localities covering most of the range of H. nummularium. Thirteen haplotypes were very unevenly distributed throughout the range of the species, and exhibited a strong phy
A study on crown interception with four dominant tree species : A direct measurement
An experiment was conducted to concentrate on the rainfall interception process of individual trees for four common species in Beijing, China, which included needle species (Platycladus orientalis and Pinus tabulaeformis) and broadleaf species (Quercus variabilis and Acer truncatum). Two types of interception storages, the maximum (Cmax) and the minimum interception storage (Cmin), were examined a
The effects of MEK1/2 inhibition on cigarette smoke exposure-induced ET receptor upregulation in rat cerebral arteries
Cigarette smoking, a major stroke risk factor, upregulates endothelin receptors in cerebral arteries. The present study examined the effects of MEK1/2 pathway inhibition on cigarette smoke exposure-induced ET receptor upregulation. Rats were exposed to the secondhand smoke (SHS) for 8 weeks followed by intraperitoneal injection of MEK1/2 inhibitor, U0126 for another 4 weeks. The urine cotinine lev
Measurements of the spin-orbit interaction and Landé g factor in a pure-phase InAs nanowire double quantum dot in the Pauli spin-blockade regime
We demonstrate direct measurements of the spin-orbit interaction and Landé g factors in a semiconductor nanowire double quantum dot. The device is made from a single-crystal pure-phase InAs nanowire on top of an array of finger gates on a Si/SiO2 substrate and the measurements are performed in the Pauli spin-blockade regime. It is found that the double quantum dot exhibits a large singlet-triplet
Rätten i den fysiska planeringen. Tre teoretiska perspektiv
Detta kapitel rör sig i spänningsfältet mellan rättssociologi och fysisk planering i syfte att visa på hur den senare kunde utvecklas genom bidrag från den förras vidgade förståelse för och av rätten. Analysen, som grundas på material från empiriska studier av utbyggnaden av 3G-systemet och av vindkraften, fokuserar rättens roll i planeringen ur tre perspektiv som är vanliga i rättssociologisk for
Tillit avgörande för den växande digitaliseringen
DEBATT. Om konsumenters data och tillit; om behov av kunskap, kompetens och kritisk blick för det datadrivna; och om behovet av att sticka hål på universitetens silos.
Genetic mapping of the barley lodging resistance locus Erectoides-k
The barley (Hordeum vulgare L.) mutant erectoides-k.32 (ert-k.32) was isolated in 1947 from an X-ray-mutant population of cultivar ‘Bonus’. The mutant was released as a cultivar in 1958 with the name ‘Pallas’ – one of the first cereal crop cultivars developed from induced mutants. ‘Pallas’ is a semi-dwarf barley cultivar known for its culm stability and resistance to lodging. In total, eight allel

Tracing Critical Realism in the Work of Åström
The aim of this chapter is to discuss the possibilities of a critical realist sociology of law set against the background of the work of Professor Karsten Åström. Thus, in the next section I give a short description of Åström’s ”sociolegal stance”, and specifically his concept of parallel norm creating processes. I then proceed, in the third section, to describe the basics of Roy Bhaskar’s critica

Extraction-Based Regression Test Selection
Frequent regression testing is a core activity in agile software development, but large test suites can lead to long test running times, hampering agility. By safe RTS (Regression Test Selection) techniques, a subset of the tests can be identified that cover all tests that can change result since the last run. To pay off in practice, the RTS overhead must be low. Most existing RTS techniques are b
The chemical, mechanical, and hydrological evolution of weathering granitoid
Surprisingly few studies connect the chemical, mechanical, and hydrological evolution of rock as it weathers to saprolite and soil. We assess this coevolution in granodiorite from Monterey Peninsula, California, by measuring changes in bulk chemistry, mineralogy, volumetric strain, the oxidation state of Fe in biotite crystals, tensile strength, abrasion rate, connected porosity, and hydraulic con
