The aim of this study is assessing the existence of a relationship between neuropsychological variables and clinical variables. 12 female patients with both nonepileptic and epileptic seizures with a mean age of 39,6 years (€12,3), followed at Psychiatric and Neurophysiology Services, were recruited. It were used the following instruments: socio demographic and a clinical interview, the LNNB and the MMSE. The results indicate that the emergence of nonepileptic seizures occurs on average 9 years after the onset of the epileptic disease; the duration of epilepsy is the clinical variable most correlated with the clinical scales of LNNB. The highest value (worst performance) was found on the scale that assesses the Intellectual Functions (30,...

Features include input solar cycle modulated cosmic ray and solar particle event spectra, based both on CREME-96, the transport of this radiation in the Martian atmosphere and regolith, including creation of secondaries, using the Geant4 Monte Carlo toolkit. Details of the atmosphere are derived from the European

This protocol aims to characterize the patients admitted in DH, through the analysis of sociodemographic and clinical data at moment of clinical admission and discharge of the unit. Another objective is to assess the degree of satisfaction with the services provided, and also quality of life (QOL) (The Short Form Health Survey SF-36), psychopathological state (Brief Symptom Inventory - BSI) and functionality (Occupational Self Assessment - OSA).In a sample of 168 individuals, (assessment between January 2009 and June 2011) 48% were male (n=80). The average age of participants was 44.4 (SD=11.9), the average age of onset of 29.7 (SD=13.3). The most frequent diagnoses were the Group of Schizophrenia, Schizotypal and Delusional Disorders at 38.7%, followed by mood disorders with 30.4%.In regard to QOL, it was found out that patients scored significantly higher on some dimensions on discharge, corresponding to a better QOL. The BSI dimensions on exit are generally lower than the results of the entrance, which means that patients have less psychopathological symptoms. The results of OSA indicate that aspects of functionality, chosen by their patients for psychosocial rehabilitation are: self care and problem-solving ability.

These observations were carried out with the 0.5m Danish Telescope at ESO. We can conclude the following: 1) Stars with a large asymmetric drift show: a) No substantially different age distribution when compared to the thin disk. Thick disk candidates show an age range from 6--7 to 12--14 Gyr and a velocity dispersion of sigma_ {{W}}}=38 +/- 10 \km; b) However, some stars have solar-like metallicity. 2) The age distributions for thin disk candidates in different [Fe/H] bins are not identical, nevertheless, no well defined age--metallicity relation can be established.

Through the use of digitised objective prism spectra, their data yielded information on each star's magnitude, spectral type, luminosity class, an estimate of [Fe/H], radial velocity and proper motions. Maximum likelihood computations showed that the disk-like component(s) in the galactic z direction is best described by a two-exponential model with scale heights of 145±10 pc and 287±13 pc. The relative normalisations of these two components vary from nearly zero at F5 to about 3.6 for G0 - G3 stars. From uvbyß photometry of 250 late-F to early-G dwarf stars the authors conclude that the intermediate population (iP II) group shows a chemical distribution compatible with that of the thick disk, and its age shows a large variation with limits of 6 and 14 Gyr. There is a shift towar...

The evolution of this event shows successive phases in time scales of a fraction of a second. It is shown that the CME observed by the LASCO/SOHO coronograph is the result of successive interactions of multiple
