To identify the risk factors and attributable mortality associated with superinfections in febrile neutropenic patients with hematologic malignancies, we prospectively evaluated 333 episodes of fever and neutropenia by means of univariate and multivariate analyses. Superinfection was defined as any infection either occurring during antibiotic therapy or(More)
In this paper we report a eight-year prospective study designed to further characterize incidence, epidemiology, specific syndromes, treatment and prognosis associated with fungal infections in neutropenic patients. During the study period 30 fungal infections were diagnosed in 30 patients among 313 episodes of fever and neutropenia (10%). There were 15(More)
PURPOSE To analyse the evolution of 8 cases of Chagas' disease after a microepidemy of 17 cases which occurred in Teotonia-RS-in 1965 and to discuss the importance of oral contamination in Chagas' disease. METHODS All 8 patients are followed at the IC/FUC-RS-Brazil since 1980. Clinical examinations, blood tests, ECG, Cx-Ray and Echo were made in 1991. (More)
There is growing interest in the use of noble liquid detectors to study particle properties and search for new phenomena. In particular, they are extremely suitable for performing direct searches for dark matter. In this kind of experiments, the light produced after an interaction within the sensitive volume is usually read-out by photomultipliers. The need(More)
We study the feasibility of performing a ν µ disappearance long-baseline experiment using a neutrino beam coming from muon decays. The advantage of such a technique with respect to the production of neutrino beams from pions is that in a muon decay both muon and electron neutrinos are produced in the same quantity. In case of ν µ → ν τ,s oscillations, the ν(More)
A liquid Argon TPC (ICARUS-like) has the ability to detect neutrino bursts from type-II supernova collapses, via three processes: elastic scattering by electrons from all neutrino species, and ν e charged current absorption on Ar with production of excited K and ¯ ν e charged current absorption on Ar with production of excited Cl. In this paper we have used(More)
Maintaining the integrity of the cuticular transpiration barrier even at elevated temperatures is of vital importance especially for hot-desert plants. Currently, the temperature dependence of the leaf cuticular water permeability and its relationship with the chemistry of the cuticles are not known for a single desert plant. This study investigates whether(More)
We assess the prospects for indirect detection of Weakly Interacting Massive Particles using a large Liquid Argon TPC detector. Signal events will consist of energetic electron (anti)neutrinos coming from the decay of τ leptons and b quarks produced in WIMP annihilation in the core of the Sun. Background contamination from atmospheric neutrinos is expected(More)

Different architectural arrangements may represent contrasting morphological solutions to different environmental pressures. This work aims to elucidate whether the crown architecture of Lychnophora ericoides (Asteraceae) modifies in response to harsh soil conditions (nutrient poor and heavy metal rich) and how its crown architecture affects its(More)
