Importance of HTML structural elements and metadata in automated subject classification

The aim of the study was to determine how significance indicators assigned to different Web page elements (internal metadata, title, headings, and main text) influence automated classification. The data collection that was used comprised 1000 Web pages in engineering, to which Engineering Information classes had been manually assigned. The significance indicators were derived using several differe

AVHRR Derived Phenological Change in the Sahel and Soudan, Africa, 1982 - 2005

The Sahel region of Africa has experienced a decrease in rainfall from the early 1960s to mid 1990s. Recent studies have detected an increased in NDVI amplitude and growing season integrated NDVI for the region since 1982. However, these studies have not examined how plant phenology has changed. Phenology examines life cycle events such as bud burst and leaf senescence. Using the software TIMESAT

Propagation of exciton pulses in semiconductors

Using toy model, we examine the propagation of excitons in Cu2O, which form localized pulses under certain experimental conditions. The formation of these waves is attributed to the effect of dispersion, non-linearity and the coupling of the excitons to phonons, which acts as dissipative mechanism.

No evidence for inbreeding avoidance in a great reed warbler population

Inbreeding depression may drive the evolution of inbreeding avoidance through dispersal and mate choice. In birds, many species show female-biased dispersal, which is an effective inbreeding avoidance mechanism. In contrast, there is scarce evidence in birds for kin discriminative mate choice, which may, at least partly, reflect difficulties detecting it. First, kin discrimination may be realized

Is there a long-lasting effect of pelvic floor muscle training in women with urinary incontinence after ischemic stroke? A 6-month follow-up study

The aim of this study was to evaluate the long-lasting effect of pelvic floor muscle training (PFMT) in women with urinary incontinence after stroke measured by quality of life parameters. Twenty-four (24/24) women with urinary incontinence after stroke, who had completed a prospective, randomised controlled and single-blinded trial evaluating the effect of 12 weeks PFMT, were included in this fol

A new parameterization of cloud droplet activation applicable to general circulation models

A new parameterization is proposed to link the droplet number concentration to the size distribution and chemical composition of aerosol and updraft velocity. Except for an empirical assumption of droplet growth, the parameterization is formulated almost entirely on first principles to allow for satisfactory performance under a variety of conditions. For a series of updraft velocity ranging from 0

Cerebral MRI on fetuses submitted to repeated cocaine administration during the gestation: an ovine model

The aim of this study was to determine the role of Magnetic Resonance Imaging (MRI) in investigating fetal cerebral lesions induced by long term exposure to cocaine during sheep pregnancy. Cerebral Magnetic Resonance Imaging was performed on two groups of fetuses at 125 days of gestation (normal gestation: 145 days). The control group consisted of eight fetuses of four pregnant ewes. The study gro

Non-covalent molecular imprinting with emphasis on its application in separation and drug development

The molecular imprinting technique can be defined as the formation of specific nano-sized cavities by means of template-directed synthesis. The resulting molecularly imprinted polymers (MIPs), which often have an affinity and a selectivity approaching those of antibody-antigen systems, have thus been coined "artificial antibodies." MIPs are characterized by their high specificity, ease of preparat

Geochemical and mineralogical investigation of the Permian-Triassic boundary in the Continental Realm of the Southern Karoo Basin, South Africa

Mineralogical and geochemical studies of the non-marine Permian–Triassic (P–Tr) boundary across two stratigraphically wellconstrained sections (Commando Drift Dam and Wapadsberg, Eastern Cape Province) in the southern Karoo Basin, South Africa, have been undertaken to provide further input on the cause of this mass extinction event, and so has a sedimentological and geochemical evaluation of a thi

Contact allergy to acrylates/methacrylates in the acrylate and nail acrylics series in southern Sweden: simultaneous positive patch test reaction patterns and possible screening allergens

In a recent study we showed that all our dental personnel/patients were detected with 2-hydroxyethyl methacrylate (2-HEMA) and 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy)phenyl]propane (bis-GMA). We studied 90 patients tested to the acrylate and nail acrylics series at our department over a 10 year period to see whether screening allergens could be found. Patch testing with an acrylate and nail ac

Crosses between frog populations reveal genetic divergence in larval life history at short geographic distance

A number of studies have documented interpopulation divergence in amphibian larval life-history traits across latitudes. Because many frogs are philopatric and have a patchy habitat distribution, genetic divergence could also exist on a much smaller geographical scale, revealed by recent estimates of population divergence using molecular markers. Whether this divergence is reflected in phenotypic

Delusional ideation and manic symptoms in potential future emigrants in Uganda.

Background. The cause of increased schizophrenia rates among immigrants in Europe is unknown. This study explores psychotic features in persons aspiring and actively planning to emigrate, prior to their potential emigration. Method. Potential future emigrants and controls in Kampala (Uganda) were screened for delusional ideation and manic symptoms, using the Peters et al. Delusions Inventory (PDI

Contractile properties of mouse single muscle fibers, a comparison with amphibian muscle fibers

Single fibers, 25-40 mu m wide and 0.5-0.7 mm long, were isolated from the flexor digitorum brevis muscle of the mouse. Force and movement were recorded (21-27 degrees C) from the fiber as a whole and, in certain experiments, from a short marked segment that was held at constant length by feedback control. The maximum tetanic force, 368 +/- 57 kN/m(2) (N = 10), was not significantly different from

Propagators and Scattering of Electromagnetic Waves in Planar Bianisotropic Slabs - An Application to Frequency Selective Structures

Scattering by planar geometries with plane metal inclusions are analysed. The metal inclusions can be of arbitrary shape,and the material of the supporting slabs can be any linear (bianisotropic) material. We employ the method of propagators to find the solution of the scattering problem. The method has certain similarities with a vector generalisation of the transmission line theory. A general rel

QT dispersion failed to estimate the global dispersion of ventricular repolarization measured using monophasic action potential mapping technique in swine and patients

The aim of this study was to evaluate whether the QT dispersion measured from 12-lead electrocardiogram (ECG) can estimate the global dispersion of ventricular repolarization (DVR) measured using a monophasic action potential (MAP) mapping technique. Monophasic action potentials were recorded from 75 +/- 12 left ventricular sites in 10 pigs and from 48 +/- 16 left or right ventricular sites in 15

Smoking and myelodysplastic syndromes

The purpose of this case-control study was to investigate tobacco smoking as a risk factor for myelodysplastic syndromes, emphasizing karyotypic aberrations as markers for exposure and risk differentiation with respect to morphology. We obtained smoking history by interview of 330 cytogenetically investigated adult myelodysplastic syndrome cases and 337 controls, matched with respect to sex, year

5-Hydroxytryptamine stimulates the formation of inositol phosphate in astrocytes from different regions of the brain

5-Hydroxytryptamine (5-HT) stimulated the turnover of phosphoinositide in primary cultures of astroglia from the cerebral cortex, striatum, hippocampus and brain stem. Ketanserin and ritanserin, selective antagonists for the central 5-HT2 receptor, inhibited the 5-HT-stimulated formation of inositol monophosphate. In contrast, there was no statistically significant accumulation of cyclic AMP after
