It is known that for n ≥ 3 centres and positive energies the ncentre problem of celestial mechanics leads to a flow with a strange repellor and positive topological entropy. Here we consider the energies above some threshold and show: Whereas for arbitrary g > 1 independent integrals of Gevrey class g exist, no real-analytic (that is, Gevrey class 1) independent integral exists.

Waste treatment processes produce odours and biological emissions to the environment, but their health effects are controversial. The aim of our study was to assess odour-associated self-reported physical symptoms among residents living near waste treatment centres. The study was conducted in the surroundings of five large-scale Finnish waste treatment centres with composting plants. In 2006, 1...

This article presents the attitude of ESP learners towards the role of Self-Access Language Learning Centres in improving their reading comprehension. It provides an evaluation of the success of these contents as well as an interpretation of students’ understanding of the related concepts. Finally it identifies factors that enhance or hinder the successful implementation of Self-Access Language...

OBJECTIVES To clarify policies regarding management of HIV-infected women, relating to pregnancy, in view of current European consensus guidelines. STUDY DESIGN Postal questionnaire survey in 36 hospitals in 11 European countries. RESULTS Responses were received from 22 (61%) centres, representing all 11 countries. In principle, antiretroviral therapy (ART) would be reviewed in treated wome...

BACKGROUND AND AIMS The "DAT-AP" (from the Spanish, "Dislipemia ATerogénica en Atención Primaria", for Atherogenic Dyslipidaemia in Primary Care) study objective is to determine to what extent published consensus guidelines for the diagnostic and therapeutic management of AD are used in the primary care setting, and to evaluate the approach of the participating physicians towards the detection,...

The structures of five of the possible six isomers of (E,E)-1,4-bis(nitrophenyl)-2,3-diaza-1,3-butadiene are reported, including two polymorphs of one of the isomers. (E,E)-1,4-Bis(2-nitrophenyl)-2,3-diaza-1,3-butadiene, C(14)H(10)N(4)O(4) (I), crystallizes in two polymorphic forms (Ia) and (Ib) in which the molecules lie across centres of inversion in space groups P2(1)/n and P2(1)/c, respecti...

OBJECTIVE To determine the contemporary survival outcomes from a whole population and identify significant predictors of survival, as contemporary population-based survival outcomes after radical cystectomy (RC) for the treatment of bladder cancer (BC) are sparse. Reports suggest a large disparity between population outcomes and those of centres of excellence. PATIENTS AND METHODS All invasiv...

background: measurement of back ground concentration of uranium in drinking water is very important for many reasons, specially, for human health. the uranium concentration in drinking water in many counties is a matter of concern for clinical and radioactive poisoning. materials and methods: the uranium concentration in drinking water is determined using laser flourimatric uranium analyzer. fo...
