We report on variational calculations of the energy E(p, ß) of asymmetric nuclear matter having p = p +pp = 0.05 to 0 .35 fm-~, and ß = (P -p~)lp = 0 to l . The nuclear hamiltonian used in this work consists of a realistic two-nucleon interaction, called °i<, that fits the available nucleon-nucleon scattering data up to 425 MeV, and a phenomenological three nucleon interaction adjusted to repro...

ß We develop an application to identify and characterize polygonal features in SAR images, based on a watershed algorithm, modified for a good robustness to radar noise. ß Our system performs a multi-scale analysis of the image. Oversegmentation is prevented by a selection of outstanding contours; regions with less prominent contours are merged ß This analysis is applied to Venus images from th...

The aim of this study was to compare the influence a final rinse with and without passive ultrasonic irrigation (PUI), using 17% ethylenediaminetetraacetic acid (EDTA) or 10% citric (CA), 2.5% sodium hypochlorite (NaOCl) PUI, on sealing ability root canal fillings. Root instrumentation performed in single-rooted premolars NaOCl as irrigant. Subsequently, roots were randomly allocated into four ...

Background The extended spectrum ß-lactamases (ESBL) are enzymes that produce resistance to ß-lactam antibiotics, including penicillins, wide spectrum cephalosporins and aztreonam, by cleavage of ß-lactam ring (BUSH & JACOBY, 2010). Since ESBL-producing bacteria are frequently associated with nosocomial infections, treatment options are becoming increasingly limited (RAWAT & NAIR, 2010). In thi...

abstract enhancing phytoextraction with aminopolycarboxylic acids (apcas) associated with fast growing and metal tolerant plants species has been proposed for the clean-up of heavy metal contaminated soils. the objectives of this study were to assess the efficiency of edta and nta for desorbing pb from soil and to compare their effects for enhancing of pb extraction with land cress (barbara ver...

BACKGROUND The study aimed to identify the most burdensome functioning domains in depression and their differential impact on the quality of life (QoL) of individuals from nine countries in Asia, Africa, Europe, and Latin America. MATERIALS AND METHODS Data from two multi-country projects-the World Health Organization's Study on Global Ageing and Adult Health (SAGE) and the Collaborative Rese...

For X > 0 and k > 0 we present a method which permits us to obtain inequalities of the type (it + a)x_l < T(k + \)/T(k + 1) < (k + ß)x'x, with the usual notation for the gamma function, where a and ß are independent of k. Some examples are also given which improve well-known inequalities. Finally, we are also able to show in some cases that the values a and ß in the inequalities that we obtain ...

(REE,Y) phosphates were synthesized in a 1 atm furnace by ß ux-growth methods involving Pb-free ß uxes. Microcrystalline (REE,Y) phosphate was precipitated from a solution of (REE,Y) chlorides or nitrates plus ammonium dihydrogen phosphate, and mixed with a M2CO3 (M = Li or Na)-MoO3 ß ux (75:25:2 molar ratio M2CO3:MoO3:REEPO4). Crystal growth was achieved over the temperature range 1350–870 °C,...

Introduction The Lathyrus/lathyrism challenge is broad-based by its nature and requires multi-disciplinary efforts of specialists in the field of epidemiology, neurology, biochemistry, chemistry, nutrition, and agronomy. The role of chemists is in systematic determination of minor natural products in L. sativus seeds so that the sole responsibility of ß-ODAP for neurolathyrism is ascertained . ...

BACKGROUND Medical staff's influence on patient outcomes has become a subject of interest. We evaluated experienced midwives and compared their performance concerning perineal lacerations (PL). METHODS In a retrospective cohort study, 1937 women with singleton pregnancies who had delivered spontaneously with a cephalic presentation by experienced midwives in the Medical University of Vienna f...
