Abstract: The history of the Etna volcano (Sicily) is marked by the alternation of brief intervals of eruptive activity and long periods of apparent inactivity. Usually during the periods of pseudo-inactivity, there are evident symptoms that the volcano is still active, e.g. fumaroles, hot springs and gaseous emissions. The variation of previous phenomena may be used to forecast seismic and volcanic- events. The aim of the research has been to evaluate and analyze the variation in emissions of ultra fine dusts and in soil Radon concentration, during the period of pseudo-inactivity, to obtain indexes able to forecast the possible events. Investigations have been carried out near two active faults on the slopes of Mt. Etna. The present paper presents the results of the monitoring survey, the analysis methodology and the development of the index to forecast possible seismic event. Research is currently in progress to refine the index which could be utilized not only to forecast possible seismic volcanic events, but also as a key to give early warning to the Civil Protection Agency so that they may be ready in time as soon as an eruptive event will occur.

Abstract: introduction: the treatment of tuberculosis is currently carried out in outpatient health services and hospitalization is only recommended for the more severe cases or for those facing social problems. in s?o paulo, however, a considerable number of tuberculosis patients are still hospitalized. objective: to study the socio-demographic and clinical-epidemiological characteristics of hospitalized tuberculosis patients in the city of s?o paulo in 2001. specific objective: to calculate tuberculosis morbimortality indicators for inpatients. methods: indicators of morbimortality of inpatients were calculated taking as sources, data from the s?o paulo state tuberculosis information system - (epitb) registration program, and the follow-up and analysis of reports and population data from deinfo/ sempla and fipe. results: a total of 2,473 tuberculosis patients were hospitalized in the city of s?o paulo in 2001. the hospitalization rate for these patients was 23.5 per 100,000 inhabitants, and the mortality rate found was 4.1 per 100,000 inhabitants with 485 deaths, yielding a fatality rate of 17.4%. discussion: the tb/hiv co-infection rate was of 32.7% among inpatients and 12.5% among those not hospitalized, showing that the aids epidemic has caused a considerable impact both in the magnitude and in the severity of the situation of hospitalized tuberculosis patients. the higher fatality rate (48.4%) is of disseminated / miliary tuberculosis, of which the majority occurs in hiv-positive patients. if, however, known hiv-positive cases are excluded, the fatality rate still remains high, i.e. 15%, showing that the severity of cases is not only due to co-infection. conclusions: taking all points into consideration, the indicators showed an alarming situation. recommendation: it is recommended that the epidemiological surveillance of municipalities establish flows and follow_up strategies for tuberculosis patients who have been hospitalized, mainly those in large urban centers, in

Computer Science , 2014,
Abstract: We investigate the space complexity of refuting $3$-CNFs in Resolution and algebraic systems. No lower bound for refuting any family of $3$-CNFs was previously known for the total space in resolution or for the monomial space in algebraic systems. We prove that every Polynomial Calculus with Resolution refutation of a random $3$-CNF $\phi$ in $n$ variables requires, with high probability, $\Omega(n/\log n)$ distinct monomials to be kept simultaneously in memory. The same construction also proves that every Resolution refutation $\phi$ requires, with high probability, $\Omega(n/\log n)$ clauses each of width $\Omega(n/\log n)$ to be kept at the same time in memory. This gives a $\Omega(n^2/\log^2 n)$ lower bound for the total space needed in Resolution to refute $\phi$. The main technical innovation is a variant of Hall's theorem. We show that in bipartite graphs $G$ with bipartition $(L,R)$ and left-degree at most 3, $L$ can be covered by certain families of disjoint paths, called $(2,4)$-matchings, provided that $L$ expands in $R$ by a factor of $(2-\epsilon)$, for $\epsilon < \frac{1}{23}$.

Abstract: due to the role of interleukin-2 (il-2) in the mediation of immune response, this cytokine has been used in the treatment of some types of cancer and infectious diseases. however, relatively high levels of this cytokine are required to achieve significant activity. the aim of this work was to study a culture medium composition designed to increase the production of il-2 by suspended murine el-4 cells. the cultivations were carried out aiming at producing il-2 in stirred bioreactors. the effects of concentration of glutamine, phorbol-12-myristate-13-acetate (pma), concanavalin a (con a), pluronic f68, and fetal calf serum (fcs) on cell viability and il-2 production were evaluated. pma alone was more efficient in il-2 production than it was in association with con a. the maximum il-2 production was around 162 ng/ml with 856 ng/ml pma and 1.45% (v/v) fcs.

Abstract: Idosos, principalmente os residentes em institui § μes de longa perman ancia, merecem aten § £o, pelo fato de apresentarem di culdades inerentes pr 3pria idade. A identi ca § £o da alimenta § £o desta popula § £o de extrema import ¢ncia para veri car a sua adequa § £o. O objetivo deste trabalho foi avaliar o per l alimentar e nutricional de 85 idosos, de ambos os sexos, residentes em moradias individuais de uma Institui § £o de Longa Perman ancia para idosos. Para a classi ca § £o do estado nutricional foi utilizado o ndice de Massa Corporal obtido por meio das medidas antropom tricas de peso e estatura. Para a estimativa do consumo alimentar foram utilizados dois recordat 3rios de 24 horas. Todos os dados foram coletados nas resid ancias dos indiv -duos. Para efeito de an lise, os idosos foram divididos em grupos segundo o IMC e as diferen §as entre os grupos foram avaliadas pela ANOVA, seguida do teste de Tukey. Diante da an lise do IMC (kg/m 2), dos 85 idosos participantes da pesquisa, 47 (55%) foram classi cados como eutr 3 cos, 23 (27%) com excesso de peso e 15 (18%) com magreza. Com rela § £o ao consumo alimentar, observou-se ingest £o inadequada de energia e de alguns micronutrientes, tais como vitamina C, zinco e folato, quando se compara o ingerido com o recomendado pela Estimated Average Requirement, das DRIa€ s. Para os micronutrientes, a ingest £o inadequada foi quanti cada em menor que 50%. Em vista do exposto, esfor §os cont -nuos devem ser realizados na vigil ¢ncia de consumo alimentar das popula § μes idosas.

Abstract: We investigate the space complexity of refuting $3$-CNFs in Resolution and algebraic systems. We prove that every Polynomial Calculus with Resolution refutation of a random $3$-CNF $\phi$ in $n$ variables requires, with high probability, $\Omega(n)$ distinct monomials to be kept simultaneously in memory. The same construction also proves that every Resolution refutation $\phi$ requires, with high probability, $\Omega(n)$ clauses each of width $\Omega(n)$ to be kept at the same time in memory. This gives a $\Omega(n^2)$ lower bound for the total space needed in Resolution to refute $\phi$. These results are best possible (up to a constant factor). The main technical innovation is a variant of Hall's Lemma. We show that in bipartite graphs $G$ with bipartition $(L,R)$ and left-degree at most 3, $L$ can be covered by certain families of disjoint paths, called VW-matchings, provided that $L$ expands in $R$ by a factor of $(2-\epsilon)$, for $\epsilon < 1/23$.
