Valodas elementu lietojuma variācijas Anglijas un Skotijas dienas laikrakstu tekstos

2019

Laikraksti ir pastāvējuši jau gadsimtiem ilgi un vēsturiski tie ir attīstījuši dažādus veidus, kas attiecināmi uz laikrakstu izmēru, mērķauditoriju, aprakstītajiem notikumiem; tomēr visiem laikrakstiem ir noteikti struktūras un satura pamatprincipi, pēc kuriem tie vadās, lai saglabātu rakstīta teksta tipiskās pazīmes visā pasaulē. Šī darba mērķis ir izpētīt valodas lietojuma variācijas dienas laikrakstu tekstos, kas parādītu, kā atšķiras tematiski atbilstošās nodaļas un valodas reģistra variācijas dažādu tipu laikrakstos dažādos publicēšanas apgabalos. Metodes: Trīs britu un skotu laikraksti ar plašāko lasītāju publiku tika izvēlēti, lai tajos noteiktu leksisko blīvumu un dažādību divās tem…

LEXOP: a lexical database providing orthography-phonology statistics for French monosyllabic words.

1999

During the last 20 years, psycholinguistic research has identified many variables that influence reading and spelling processes. We describe a new computerized lexical database, LEXOP, which provides quantitative descriptors about the relations between orthography and phonology for French monosyllabic words. Three main classes of variables are considered: consistency of print-to-sound and sound-to-print associations, frequency of orthography-phonology correspondences, and word neighborhood characteristics.

Synthesis and Magnetic Properties of Novel Azamacrocyclic LnIII, CuII, FeIII, and SrII Complexes and Conformational Analysis of the Ligands

2008

Hexaalkoxy-substituted azamacrocyclic metal complexes 1 · MXn [MXn = FeCl3, CuCl2, SrCl2, Ln(NO3)3; Ln = La, Pr, Eu, Ho, Er] with various chain lengths were prepared by a convergent approach using 1,2-bisalkoxy-4,5-diamines 3 and 4-alkoxy-pyridine-2,6-dicarbaldehydes 4 as key building blocks for template-assisted cyclocondensation. Metal complexes 1 · MXn were considered as potential metallomesogens. However, differential scanning calorimetry and optical polarizing microscopy of 1 · MXn did not reveal any mesomorphism. The magnetic susceptibility shows deviation from Curie-like behavior. Due to ligand field effects the effective magnetic moments are a function of the temperature. In order t…

Research Regarding the Influence of Raw Material and Woven Fabric Geometry on the Air Permeability of Mattress

2017

Abstract Properties of woven fabrics are influenced by many factors: the nature of raw materials, woven fabric geometry and density, technological parameters of the weaving operation and finishing. The main purpose of this research paper is to increase the performance of woven process during mattress manufacturing by choosing the right woven fabric geometry and raw material. The variation in air permeability depends on the area density, linear density, loop length and thickness of yarns. To obtain woven fabric samples were used several types of classic yarns, also ecological yarns like organic cotton and bamboo viscose. On the other side, tests results show the fabric resistance regarding a…

Evaluation of thin film adhesion to a compliant substrate by the analysis of progressive buckling in the fragmentation test

2009

The interface toughness of a thin coating/compliant substrate system is estimated based on the evolution of coating buckle patterns in the fragmentation test. The linear density of coating buckles as a function of applied strain is determined experimentally for a SiOx coating deposited on a polyethylene terephthalate film. A three-dimensional non-linear finite element model is developed to simulate the process of buckle formation in a single narrow coating strip. The elastic energy released during buckling-driven delamination is obtained from the energy balance in the system before and after the buckling event. Both the interface adhesion and the total energy release rate, which includes th…

Smoking and small, dense low-density lipoproteins.

High population density in bank voles stimulates food hoarding after breeding.

1998

The effects of conspecific density (i.e. risk of intraspecific competition) on hoarding behaviour were studied in breeding pairs of bank voles, Clethrionomys glareolus. I simulated high population density by using odours of conspecifics, to exclude the direct effects of exploitation or interference competition for food. The pairs of bank voles hoarded only at the end of their breeding season. Hoarding was not correlated with whether the voles had a litter during the experiment or their litter size, but was more likely at the high population density and for pairs with small females. This may indicate that smaller females especially make caches in the autumn, possibly to ensure better winter …

Significant liver fibrosis assessed using liver transient elastography is independently associated with low bone mineral density in patients with non…

2017

Background Metabolic bone disorders frequently occur in patients with chronic liver disease; however, the association between liver fibrosis and bone mineral density in patients with non-alcoholic fatty liver disease (NAFLD) is unclear. Methods This is a cross-sectional analysis of 231 asymptomatic subjects (160 women, 61.6 years old) from a university hospital setting, between February 2012 and December 2014. Bone mineral density (BMD) was measured at the lumbar spine, femur neck, and total hip using dual-energy X-ray absorptiometry (DXA). Liver fibrosis and steatosis were assessed using transient elastography. Results Among a total of 231 individuals, 129 subjects (55.8%) had NAFLD. BMDs …

Disorder-induced gap in the normal density of states of the organic superconductorκ-(BEDT-TTF)2Cu[N(CN)2]Br

2015

The local density of states (DOS) of the organic superconductor κ-(BEDT-TTF)2Cu[N(CN)2]Br, measured by scanning tunneling spectroscopy on in situ cleaved surfaces, reveals a logarithmic suppression near the Fermi edge persisting above the critical temperature T(c). The experimentally observed suppression of the DOS is in excellent agreement with a soft Hubbard gap as predicted by the Anderson-Hubbard model for systems with disorder. The electronic disorder also explains the diminished coherence peaks of the quasi-particle DOS below T(c).

Manipulating and squeezing the photon local density of states with plasmonic nanoparticle networks

2010

International audience; In this Brief Report, we show that when interconnected networks of gold particles are deposited onto a clean planar surface, they strongly modify the photonic local density of states LDOS in the immediate proximity of the self-assembled nanoparticles. They represent unique architectures for the subwavelength patterning of initially flat photonic LDOS. Moreover, we show that their local spectral signatures are well suited for the generation of sites able to enhance molecular fluorescence intensity.
