Graphic correlation using graptolites and conodonts provides a high-resolution timescale for correlating from coastal to deep oceanic sections and, thereby, also a detailed record of the sequence of changes during the Mulde Secundo-Secundo Event. That interval includes sedimentary facies otherwise unknown in older Wenlock to early Ludlow strata on Gotland. The identified sequence of changes includ
Aim:The aim was to analyse any associations between socio-demographic and psychosocial factors and different features of the metabolic syndrome in a geographically well-defined population of middle-aged women. Methods:A population of 10 766 Caucasian women aged 50-59 years was investigated regarding biological and socio-demographic conditions, physical activity, dietary habits, aspects of quality
Background The clinical distinction between Alzheimer's disease (AD) and dementia with Lewy bodies (DLB) is sometimes difficult, particularly in mild cases. Although CSF markers such as amyloid beta 42 (A beta 42) and P-tau can distinguish between AD and normal controls, their ability to distinguish between AD and DLB is not adequate. Objective This study aims to investigate whether CSF markers, i
The growing energy prices and energy consumption caused the interest about buildings with low energy consumption such as Passive house. Energy demand in households accounts for around one forth of the final energy needs in the EU (Intelligent Energy Europe 2006), and it is a potential for energy demand reduction. At the same time, environment protection with a reduction of CO2 emissions nowadays i
AB Ph. Nederman manufactures capture at source extractors that remove dust and fumes from a specific area. These extractors are made of a positioning joint which has the purpose to hold up the extractors’ hood. Presently this joint is made of a double ball joint; this doesn’t however work in a satisfying way. First and foremost it is hard to move the joint when repositioning the hood; this is not
Enzymer är biologiskt aktiva molekyler med en katalytisk förmåga. Detta innebär enzym kan medföra en omvandling av ett ämne i en reaktion som normalt inte sker spontant. Laccas är ett enzym som kan bryta ner (oxidera) fenolföreningar, och i naturen förekommer det i växter, svampar och bakterier där det fyller olika funktioner.
Degradation of the dry semiarid ecosystems in the Mu Us Sandy Land of north central China was explored using high-resolution satellite images from 1978, 1987 and 1996. This study monitored both changes in grassland biomass production and reclamation activities to detect the nature and scale of land degradation since major economic reforms were introduced in 1978. The position of the high-resolutio
VOR, the versatile optimal resolution chopper spectrometer, is designed to probe dynamic phenomena that are currently inaccessible for inelastic neutron scattering due to flux limitations. VOR is a short instrument by the standards of the European Spallation Source (ESS), 30.2m moderator to sample, and provides instantaneous access to a broad dynamic range, 1-120 meV within each ESS period. The sh
We investigate whether stellar-mass black holes have to receive natal kicks in order to explain the observed distribution of low-mass X-ray binaries containing black holes within our Galaxy. Such binaries are the product of binary evolution, where the massive primary has exploded forming a stellar-mass black hole, probably after a common envelope phase where the system contracted down to separatio
We present extensive density-functional theory (DFT) based calculations of the clean Rh(111) surface and of CO/Rh(111) overlayer systems. We study both ground-state structural properties and core-level shifts from differences in total energies at different coverages and adsorption sites. Most results are obtained using using norm-conserving or ultrasoft pseudopotentials. The overall reliability of
It is shown how first-order performance estimation of high-orderadaptive optics (AO) systems may be efficiently implemented in a hybridnumerical simulation by the use of 1) sparse matrix techniques forwavefront reconstruction, 2) undersampled pupil-plane turbulence-inducedaberrations, and 3) analytical models that compensate - in the limit ofinfinite exposure time - for the errors introduced by un
A two-phase hollow-fiber (HF) liquid-phase microextraction (LPME) method was developed for determination of a quaternary ammonium compound surfactant, dicocodimethylammonium chloride, in aqueous samples. The porous HF was fixed on a metal rod support and was impregnated with approximately 6.6 mu L of organic extractant, which was immobilized in the HF pores. Surfactant extraction was facilitated b
Summary The leaking of water through roofs is a major problem in many parts of Tunisia. As a part of a collaboration between "École N: ionale d'Ingénieurs de Tunis" (E.N.I.T.) and Lund University, Institute of Science and Technology (L.N.T.H.), Sweden, a measuring method has been developed to compare the watertightness of different roofing membranes. With the method, three roof structues with diff
Objective To standardize the evaluation of regional fetal brain blood perfusion, using power Doppler ultrasound (PDU) to estimate the fractional moving blood volume (FMBV) and to evaluate the reproducibility of this estimation. Methods Brain blood perfusion was evaluated in 35 normally grown fetuses at 28-30 weeks of gestation, using PDU. The following cerebral regions were included in the PDU col
The user-centered design or usability design or human computer interaction there are very close or similar concept, and a very wide subject of study. The Rational Unified Process is very complex by itself. There are many criticisms again The Rational Unified process because it is alleged lack of tools and helps in the user-centered development. Relating these areas by finding out the relationships
When did the Reformation end? Reformation, confessionalization and the representation of Martin Luther in Swedish 16th-century printIn the past decades, Swedish scholars have used the concept of the Reformation to refer to a long process of religious change in Sweden between 1527 and 1593. The influence from the term ”the long reformation” used in the Anglo-Saxon world is tangible. Instead, this e
We first derive necessary and sufficient stiff order conditions, up to order four, for exponential splitting schemes applied to semilinear evolution equations. The main idea is to identify the local splitting error as a sum of quadrature errors. The order conditions of the quadrature rules then yield the stiff order conditions in an explicit fashion, similarly to that of Runge–Kutta schemes. Furth
