Development of a Short-Term Ozone Prediction Tool in Campo Grande-MS-Brazil Area Based on Meteorological Variables  [PDF]
Amaury de Souza, Flavio Aristones, Hamilton Germano Pav?o, Widinei Alves Fernandes
Open Journal of Air Pollution (OJAP) , 2014, DOI: 10.4236/ojap.2014.32005

The objective of this study was to develop a model to predict the concentration of ozone. The measurements of ozone were conducted at the Federal University of Mato Grosso do Sul. The predictor variables related to climate were supplied by Embrapa Gada de Corte. Analyses of the data show a strong correlation between ozone and wind speed (0.75), humidity (?0.64) and temperature (0.41), as the factors that affect levels of concentration ozone. The observed and predicted values of daily ozone had a correlation coefficient (R) of 0.69.

Temporal Variation of the Concentration of Carbon Monoxide in the Center West of Brazil  [PDF]
Amaury de Souza, Flavio Aristones, Gustavo Becker Modesto Silva, Widinei Alves Fernandes, Catia Braga
Atmospheric and Climate Sciences (ACS) , 2014, DOI: 10.4236/acs.2014.44051
Abstract: South Mato Grosso has been developing very rapidly in recent decades, and it is clearly leaving behind the status of being solely an agricultural region to become an important state in the areas of commerce and industry. Nevertheless, it is still possible to observe the harmful effects of atmospheric pollution due to biomass burning activities, even if those actions are being systematically reduced in the state throughout the past several years. This kind of pollution persists not only due to local activities but also due to the pollution of other states and even other border countries. Satellite remote sensing has proven to be an important tool of environmental control vis-à-vis the ease of data acquisition, accuracy and wide temporal range. A study has been conducted of spatial and temporal concentration of carbon monoxide (CO) in the state of South Mato Grosso from 2001 through 2012 using the MOPITT sensor onboard the TERRA satellite. The carbon monoxide comes principally from the incomplete combustion of vehicles engines and biomass burnings. A direct correlation of the CO concentration in the state of South Mato Grosso is observed precisely during the months of drought (August to October), for which the number of fire outbreaks is the highest of the year.

Poverty determinants of acute respiratory infections among Mapuche indigenous peoples in Chile's Ninth Region of Araucania, using GIS and spatial statistics to identify health disparities
Flavio Rojas
International Journal of Health Geographics , 2007, DOI: 10.1186/1476-072x-6-26
Abstract: Hospital discharge records from Health Services North N = 24,126 patients, year 2003, and 7 hospitals), Health Services South (N = 81,780 patients and 25 hospitals); CAS-2/Family records (N = 527,539 individuals, 439 neighborhoods, 32 Comunas).Given the over-dispersion of data and the clustered nature of observations, we used the global Moran's I and General G Gettis-Ord procedures to test spatial dependence. These tests confirmed the clusters of disease and the need to use spatial regression within a General Linear Mixed Model perspective.Health outcomes indicate significantly higher morbidity rates for the Mapuche compared to non-Mapuche in both age groups < 5 and 15–44, respectively; for the groups 70–79 and 80 + years of age, this trend is reversed. Mortality rates, however, are higher among Mapuches than non-Mapuches for the entire Ninth Region and for all age groups. Mortality caused by respiratory infections is higher among Mapuches than non-Mapuches in all age-groups. A major finding is the link between poverty and respiratory infections.Poverty is significantly associated with respiratory infections in the population of Chile's Ninth Region. High deprivation areas are associated with poverty, and poverty is a predictor of respiratory infections. Mapuches are at higher risk of deaths caused by respiratory infections in all age groups. Exponential and spherical spatial correlation models were tested to estimate the previous association and were compared with non-spatial Poisson, concluding that significant spatial variability was present in the data.This article addresses some aspects of the relationship between poverty and disease. The study area is located in Chile's Ninth Region, also known as Araucanía, the poorest of the country's 13 regions, and one where income distribution reveals inequality that is not only the worst in the country, but the worst in the world, with a Gini coefficient of 0.58 [1,2]. The main goal of this article is to show the link be
A voz dos cientistas críticos
Lewgoy, Flavio;
História, Ciências, Saúde-Manguinhos , 2000, DOI: 10.1590/S0104-59702000000300019
Abstract: the intricate debate over genetically modified organisms (gmos) involves powerful economic interests, as well as ethical, legal, emotional and scientific aspects, some of which are dealt with in this paper. (it is possible to identify two main groups of scientists across the gmos divide: the triumphalist and the critical group.) scientists in the triumphalist group state that gmos and their derivatives are safe for the environment and do not offer health hazards any more than similar, non-genetically modified, products. this view is disputed by the critical scientists, who are prompted by the scarcity of studies on the environmental impacts and toxicity of gmos, and who point out flaws in tests performed by the same companies which hold the patents. they are also critical of the current state of the process of gene transference, lacking accuracy, a fact which, coupled with the scant knowledge available about 97% of the genome functions, may produce unforeseeable effects with risks for the environment and public health yet to be assessed. examples of such effects are: the transference of alien genes [??] to other species, the emergence of toxins, the creation of new viruses, the impacts on beneficial insects and on biodiversity in general.
Fontes alternativas para uma história das ciências
Edler, Flavio;
História, Ciências, Saúde-Manguinhos , 1995, DOI: 10.1590/S0104-59701995000100008
Abstract: in this study we call attention to the importance of 'manguinhos' scientific collections, which preserve a major portion of the memory of scientific practice as developed by brazilian researchers in the field of biomedical sciences. we make use of these collections to approach some little-known aspects of scientific activity: the historical evaluation of forms of zoological classification and efforts at legitimating scientific practice.
Agentes morais e a identidade da filosofia de Hume
Williges, Flavio;
Kriterion: Revista de Filosofia , 2011, DOI: 10.1590/S0100-512X2011000200010
Abstract: the standard interpretion of hume's philosophy presents him both as a radical skeptic regarding rational claims about the adequate foundation of our belief system and as a naturalist who maintained that our beliefs (though rationally ungrounded) cannot be given up in ordinary life, due to natural drives and sentiments. this paper purports to show that hume's naturalism can and should be interpreted as a method for addessing philosophical concepts (ideas and beliefs,to use hume's jargon) that incorporates unreflected elements ofordinary life (such as natural sentiments and drives) and assigns to them the same theoretical status that abstract processes such as reasons and arguments have. a philosophy that warrants unreflected mechanisms in the treatment of philosophical problems is what hume calls a "true philosophy". such philosophy is compatible with the more radical forms of skepticism, because the unreflected mechanisms that bring about ideas are imune to doubt. to ilustrate the theses put forth here and so as to render my characterization of naturalism more persuasive, i describe briefly and in broad terms at the end of the paper hume's view of moral agency.
Experiência clínica com o uso de infliximab em 44 portadores de doen?a de Crohn
Steinwurz, Flavio;
Arquivos de Gastroenterologia , 2003, DOI: 10.1590/S0004-28032003000300012
Abstract: aim: to evaluate the efficacy of infliximab in the treatment of patients with active crohn's disease or with fistulas. methods: forty four patients with crohn's disease, resistant to conventional therapies, were treated with 5 mg/kg endovenous infliximab infusions. results: thirty of them (68.2%) improved, with important reduction on disease activity levels, measured by the cdai (crohn's disease activity index). eight (57.1%) of 14 patients with fistulas also showed good results, with closure or important reduction in their flow. the drug was well tolerated in all cases. conclusion: the use of infliximab in these cases seems to be a good therapeutic option, with low rates of side effects.

Modelo teórico de exposi??o a risco para transmiss?o do vírus HIV em usuários de drogas
Pechansky, Flavio;
Revista Brasileira de Psiquiatria , 2001, DOI: 10.1590/S1516-44462001000100011
Abstract: after a brief review on the challenges to approach aids and hiv transmission, especially among drug users, some theoretical models that try to explain and relate substance use and abuse and hiv exposure are described. core concepts of social learning theories are also described and applied as a basis to the understanding of behaviors associated to drug use, emphasizing the importance of the user's surrounding environment. the classical health belief model is also illustrated, highlighting its role in the development of actions and preventive programs associated to aids. finally, based on the models described, an original model on hiv exposure among drug users is proposed, in which elements related to information, schooling, gender, and age serve as a guidance and interfere with the attitudes regarding drug use and risk perception, generating a cascade effect that leads to the increase of hiv infection among these individuals.
