We report a case of a m.n suffering esophagus adenocarcinom. who acquired catheter associated bacteriem.a caused by a coagulase negative Staphylococcus. This CoNS was sensible to linezolid, teicoplanine, vancom.cin and rifam.icin. This inform.tion was relevant for antibiotherapy planning. The patient was successfully treated with teicoplanin together with the catheter exchange. In conclusion, infections should be treated with adequate doses and duration of antibiotics together with catheter exchange. Pre-em.tive m.asurem.nts in the cancer patient and establishing the m.st adequate treatm.nt are im.erative for obtaining good results.

This work presents a num.rical sim.lation of the flow field in a liquid propellant rocket engine cham.er and exit nozzle using techniques to allow the results to be taken as starting points for designing those propulsive system.. This was done using a Finite Volum. m.thod sim.lating the different flow regim.s which usually take place in those system.. As the flow field has regions ranging from.the low subsonic to the supersonic regim.s, the num.rical code used, initially developed for com.pressible flows only, was m.dified to work proficiently in the whole velocity range. It is well known that codes have been developed in CFD, for either com.ressible or incom.ressible flows, the joint treatm.nt of both together being com.lex even today, given the sm.ll num.er of. references available in this area. Here an existing code for com.ressible flow was used and prim.tive variables, the pressure, the Cartesian com.onents of the velocity and the tem.erature instead of the conserved variables were introduced in the Euler and Navier-Stokes equations. This was done to penult the treatm.nt at any m.ch num.er. Unstructured m.shes with adaptive refinem.nts were em.loyed here. The convective term. were treated with upwind first and second order m.thods. The num.rical stability was kept with artificial dissipation and in the spatial coverage one used a five stage Runge-Kutta schem. for the Fluid m.chanics and the VODE (Value of Ordinary Differential Equations) schem. along with the Chem.in II in the chem.cal reacting solution. During the developm.nt of this code sim.lating the flow in a rocket engine, com.arison tests were m.de with several different types of internal and external flows, at different velocities, seeking to establish the confidence level of the techniques being used. These com.arisons were done with existing theortical results and with other codes already validated and well acceptal by the CFD com.unity.

We prove that the existence of positively expansive m.asures for continuous m.ps on com.act m.tric spaces im.lies the existence of e 〉 0 and a sequence of （m. e）-separated sets whose cardinalities go to infinite as m.→∞. We then prove that m.ps exhibiting such a constant e and the positively expansive m.ps share som. properties.

Background:Parrots(Psittacidae Fam.ly)are one of the m.st colorful groups of birds in the world,their colors pro-duced both structurally and via unusual pigm.nts(psittacofulvins).m.st species are considered to be m.nogam.us,and m.ny have been viewed historically as sexually m.nom.rphic and ***,studies using m.rphom.tric analysis and spectrophotom.tric techniques have revealed sexual size dim.rphism.and also sexual plum.ge color dim.rphism.am.ng som. *** m.nk Parakeet(m.iopsitta m.nachus),a native parrot of South Am.rica,is an interesting species for the study of plum.ge coloration and size since it is considered sexually m.no-chrom.tic and ***,recent studies show that the m.nk Parakeet has extra-bond paternity behavior and even breeding trios,which suggests that sexual selection m.y play an im.ortant role in this species,and that it m.ght have sexually dim.rphic plum.ge(albeit im.erceptible by hum.ns)and be dim.rphic in ***:For the determ.nation of plum.ge color we used spectrophotom.try in the range of avian vision(300-700 nm.and perform.d a m.rphological ***:Our spectrophotom.tric results indicate that the m.nk Parakeet shows subtle sexual plum.ge color dim.r-phism.in three(crown,nape and wing)out of twelve body ***,our m.rphom.tric analysis showed that there are subtle sex differences in body size(bill and weight).Conclusions:Although the m.nk Parakeet shows extra-bond paternity and breeding trio behaviors which could increase sexual dim.rphism.these behaviors occur am.ng highly related individuals;perhaps the high rate of inbreeding is responsible for the attenuation of sexual plum.ge color dim.rphism.and sex differences in body size observed.

We revise the notion of von Neum.nn regularity in JB^＊-triples by finding a new characterisation in term. of the range of the quadratic operator Q（a）. We introduce the quadratic conorm.of an elem.nt a in a JB^＊-triple as the m.nim.m.reduced m.dulus of the m.pping Q（a）. It is shown that the quadratic conorm.of a coincides with the infim.m.of the squares of the points in the triple spectrum.of a. It is established that a contractive bijection between JBW^＊-triples is a triple isom.rphism.if, and only if, it preserves quadratic conorm.. The continuity of the quadratic conorm.and the generalized inverse are discussed. Som. applications to C^＊-algebras and von Neum.nn algebras are also studied.

AIm. To determ.ne whether the hem.tocrit （Hct） at adm.ssion or at 24 h after adm.ssion was associated with severe acute pancreatitis （AP）, organ failure （OF）, and pancreatic necrosis. m.THODS： A total of 336 consecutive patients with a first AP episode were studied. Etiology, Hct values at adm.ssion and at 24 h, developm.nt of severe AP according to Atlanta＇s criteria, pancreatic necrosis, OF and m.rtality were recorded. Hem.concentration was defined as Hct level 〉44% for m.les and 〉40% for fem.les. The t-test and ;x^2 test were used to assess the association of hem.concentration to the severity, necrosis and OF. Diagnostic accuracy was also determ.ned. RESULTS： Biliary disease was the m.st frequent etiology （n = 148）. m.an Hct levels at adm.ssion were 41±6% for fem.les and 46±7% for m.les （P〈0.01）. Seventyeight （23%） patients had severe AP, and OF developed in 45 （13%） patients. According to contrast-enhanced com.uted tom.graphy scan, 36% （54/150） patients showed pancreatic necrosis. Hct levels were elevated in 58% （55/96） and 61% （33/54） patients with interstitial and necrotizing pancreatitis, respectively. Neither Hct levels at adm.ssion nor hem.concentration at 24 h were associated with the severity, necrosis or OF. Sensitivity, specificity and positive predictive values for both determ.nations were very low; and negative predictive values were between 61% and 86%, being the highest value for OF. CONCLUSION： Hct is not a useful m.rker to predict a worse outcom. in acute pancreatitis. In spite of the high negative predictive value of hem.concentration, the prognosis gain is lim.ted due to an already high incidence of m.ld disease.

Based on the concentration of m.lathion used in the field, we evaluated the genotoxic potential of low concentrations of this insecticide on m.ristem.tic and F1 cells of Allium.cepa and on rat hepatom. tissue culture（HTC cells）. In the A. cepa, chrom.som.l aberrations（CAs）, m.cronuclei（m.）, and m.totic index（m.） were evaluated by exposing the cells at 1.5,0.75, 0.37, and 0.18 m./m.L of m.lathion for 24 and 48 hr of exposure and 48 hr of recovery tim.. The results showed that all concentrations were genotoxic to A. cepa cells. However,the analysis of the m. has showed non-relevant effects. Chrom.som.l bridges were the CA m.re frequently induced, indicating the clastogenic action of m.lathion. After the recovery period, the higher concentrations continued to induce genotoxic effects, unlike the observed for the lowest concentrations tested. In HTC cells, the genotoxicity of m.lathion was evaluated by the m. test and the com.t assay by exposing the cells at 0.09, 0.009, and0.0009 m./5 m.L culture m.dium. for 24 hr of exposure. In the com.t assay, all the concentrations induced genotoxicity in the HTC cells. In the m. test, no significant induction of m. was observed. The genotoxicity induced by the low concentrations of m.lathion presented in this work highlights the im.ortance of studying the effects of low concentrations of this pesticide and dem.nstrates the efficiency of these two test system. for the detection of genetic dam.ge prom.ted by m.lathion.
