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 Pavo, 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.

Effects of Air Pollution on Disease Respiratory: Structures Lag  [PDF]
Amaury de Souza, Yuming Guo, Hamilton Germano Pavo, Widinei Alves Fernandes
Health (Health) , 2014, DOI: 10.4236/health.2014.612163
Abstract: Objective: Little evidence is available on the association between ozone exposure and health in Campo Grande, Brazil. In this study, we aimed to examine the effects of surface ozone concentrations (O3) on respiratory morbidity in Campo Grande, Brazil during the period from January 1st, 2008 to December 31st, 2011. Methods: Daily data on respiratory hospital admissions, O3, mean temperature, and relative humidity were collected at Campo Grande, Brazil. A Poisson time series model was used to examine the effects of O3 on hospital admissions, while controlling for seasonality, long-term trend, temperature and relative humidity. A distributed lag non-linear function was used for O3, temperature, and relative humidity. We examined the effects of O3 on different age groups (0 - 4 years, 5 - 60 years and >60 years). Results: The ozone-respiratory morbidity relationship was non-linear, with a threshold at 13 ppb (less than 25% percentile of ozone distribution). We estimated the relative risk of hospital admission at 75% percentile of O3 distribution compared with associated with 25% of percentile of O3 distribution. The O3 effect on respiratory morbidity was delayed by two days and lasted for 4 days for all age groups except people aged 5 - 60 years. Children and the elderly were much more vulnerable to ozone pollution than people aged 5 - 60 years. Conclusions: This study suggests that ozone pollution has negative impacts on respiratory diseases in Campo Grande, Brazil. Children and the elderly were susceptible to O3 exposure. These findings should be used to develop policies for protecting people from O3 pollution.
Air quality and acute respiratory disorders in children
Amaury de Souza,Hamilton Germano Pavo,Giancarlo Lastoria,Antonio Concei??o Paranhos Filho
Revista Brasileira em Promo??o da Saúde , 2011,
Abstract: Objective: To evaluate the relationship between air pollution and acute respiratory disorders in children. Methods: An ecological study of time series conducted in public health units in the city of Campo Grande-MS, Brazil, from January 1, 2004 to December 31, 2007. Dailydata of O3 (ozone) were analyzed and, as outcome variables, 16,981 emergency pediatric consultations for respiratory symptoms; including in control model the variables related to time trend; seasonality; minimum, maximum and average temperature; relative humidity;rainfall and respiratory infections. We determined the Pearson correlation coefficient of respiratory diseases in relation to climatic parameters for the years 2004-2007. Results: Only O3 had a positive and statistically significant association, both with all emergency care attendances for respiratory complaints, as with these due to symptoms in lower airways. The daily average concentrations of O3 did not exceed the recommended daily limits. Conclusion: We found associations between air pollution and the number of emergencypediatric consultations for respiratory causes in Campo Grande, although the levels of monitored pollutant ozone remained below recommended levels throughout the study period.
Potenciais impactos da variabilidade climática sobre a morbidade respiratória em crian?as, lactentes e adultos
Souza, Amaury de;Fernandes, Widinei Alves;Pavo, Hamilton Germano;Lastoria, Giancarlo;Albrez, Edilce do Amaral;
Jornal Brasileiro de Pneumologia , 2012, DOI: 10.1590/S1806-37132012000600005
Abstract: objective: to determine whether climate variability influences the number of hospitalizations for respiratory diseases in infants, children, and adults in the city of campo grande, brazil. methods: we used daily data on admissions for respiratory diseases, precipitation, air temperature, humidity, and wind speed for the 2004-2008 period. we calculated the thermal comfort index, effective temperature, and effective temperature with wind speed (wind-chill or heat index) using the meteorological data obtained. generalized linear models, with poisson multiple regression, were used in order to predict hospitalizations for respiratory disease. results: the variables studied were (collectively) found to show relatively high correlation coefficients in relation to hospital admission for pneumonia in children (r2 = 68.4%), infants (r2 = 71.8%), and adults (r2 = 81.8%). conclusions: our results indicate a quantitative risk for an increase in the number of hospitalizations of children, infants, and adults, according to the increase or decrease in temperature, humidity, precipitation, wind speed, and thermal comfort index in the city under study.

Revista de Geografía, Norte Grande , 2010,
Abstract: The objective of this study was to evaluate the climate conditions of Mato Grosso do Sul, using the index of temperature and humidity (ITU), and present the bioclimatic mapping relating to thermal comfort. The ITU values were estimated from data of temperature and relative humidity for the period 1979 to 2008. Four intervals of ITU were used to classify human performance (ITU<74: comfort; 7484: extremely hot), and two intervals to classify the Livestock (79< ITU<84: dangerous and ITU>84: emergency). We conclude that the prevailing mood is one of two alternating seasons throughout the year: hot and humid summer and dry winter with warmer temperatures, the results showed a higher risk of thermal discomfort during the period from October to April, compared to the period between May and September. The most critical period occurred between December and March. Although it was observed that with ITU values between 77.9 and 83.9, humans and animals can suffer some degree of heat stress during the hottest hours of the day, negatively affecting both.
Heteronomia e imputabilidade na fundamenta??o da metafísica dos costumes
Pavo, Aguinaldo;
Kriterion: Revista de Filosofia , 2002, DOI: 10.1590/S0100-512X2002000100008
Abstract: i intend to discuss the way as kant relates the concepts of freedom and morality in the foundations. in this book, kant argues that" free will and will submitted to moral laws are one and same". apparently just the autonomous will would be free, not remaining other alternative that is not to assimilate the heteronomous will to the natural necessity. that consequence would provoke an embargo of the imputability of immoral actions. i want to defend that, although kant has obscure the distinctions between free will and moral will, if we concentrate on analyzes of the concept of will in foundations ii, we can defend that not just the autonomy, but the heteronomy is also chosen freely, turning intelligible, like this, the imputability of immoral acts. i sustain, therefore, that it's possible, in spite of the ambiguities of kant, to think the moral imputability starting from internal conceptual resources to foundations. thus, it won't be necessary to invoke the distinction between wille and willkür, not even other works to solve this problem.
O caráter insondável das a??es morais em Kant
Pavo, Aguinaldo;
Trans/Form/A??o , 2007, DOI: 10.1590/S0101-31732007000100008
Abstract: we may say, on the basis of the groundwork, that the moral actions are always unfathomable and that the immoral actions are unfathomable just when dress the conformity to the duty, therefore when they are contrary to the duty are fathomable. but in the critique of pure reason (b 579) kant affirms that "the real morality of actions, their merit or guilt, even that of our own conduct, thus remains entirely hidden from us". therefore do not we know how much is ascribable to the pure effect of freedom or to the simple nature. thus, kant looks defends two positions. one, proclaiming that immoral actions are partially unfathomable, another a total obscurity of the moral quality of the actions. i judge, however, that, at bottom, kant can maintain, without fall in contradiction, that (a) the contrary actions to the duty signal the wickedness of a maxim and that (b) the moral merit or moral unworthy can never be observed. to first alternative is assumed by kant to account for experience of immoral actions (cf. religion). the second thesis looks to have an eminently speculative bottom. it aims to show that moral quality of a maxim is undecidable metaphysically.
O papel das inclina es na filosofia moral de Kant
Pavo, Aguinaldo
Veritas , 2008,
Abstract: A filosofia moral de Kant pode ser criticada com base na alega o de que ela, ao exigir uma austera disposi o de animo para que se possa atender às obriga es morais, n o deixa qualquer espa o para as inclina es. Certamente um dos focos dessa leitura se encontra na se o de fundamenta o, em que Kant se refere ao ato caritativo de um filantropo insensível. Essa passagem parece apoiar a interpreta o segundo a qual a moral em Kant requer a supress o das inclina es, para que a a o tenha valor moral. Daí, aparentemente, se justificar a famosa crítica de Schiller ao rigorismo de Kant. Postas assim as coisas, poder-se-ia dizer que Kant é, em parte, responsável por essas incompreens es. Contudo, é possível defender, com base nas próprias premissas da filosofia moral Kantiana, que as inclina es n o retiram o valor moral de uma a o. O que a moral de Kant exige é que o fundamento de determina o das a es n o sejam as inclina es. Ora, isso é diferente de se pretender a supress o das inclina es. Com efeito, essa pretens o seria contraditória com a natureza finita do homem, n o sendo, de modo algum, exigida pela moral de kant. Kant’s moral philosophy can be criticized on the basis of the allegation that, requiring an austere disposition for attending to moral obligations, does not leave any room for inclinations. The focus of that reading is found in Groundwork I in which Kant refers to the charitable act of an insensible philanthropist. This passage seems to support the interpretation that morality in Kant requires the suppression of inclinations for an action to have moral value. Hence Schiller’s wellknown criticism of Kant’s rigorism. Kant is in part responsible for such misunderstandings. However, it is possible to defend Kantian moral philosophy, on the basis of the premise that inclinations do not withdraw the moral value of an action. Kant’s morality only requires that the determining ground of actions cannot be inclinations, which is different from the suppression of inclinations. Indeed, that pretension would contradict the finite nature of man, and is not required by Kant’s moral philosophy.

Structure and anticoagulant properties of sulfated glycosaminoglycans from primitive Chordates
Anais da Academia Brasileira de Ciências , 2002, DOI: 10.1590/S0001-37652002000100007
Abstract: dermatan sulfates and heparin, similar to the mammalian glycosaminoglycans, but with differences in the degree and position of sulfation were previously isolated from the body of the ascidian styela plicata and ascidia nigra. these differences produce profound effects on their anticoagulant properties. s. plicata dermatan sulfate composed by 2-o-sulfateda-l-iduronic acid and 4-o-sulfated n-acetyl-b-d-galactosamine residues is a potent anticoagulant due to a high heparin cofactor ii activity. surprisingly, it has a lower potency to prevent thrombus formation on an experimental model and a lower bleeding effect in rats than the mammalian dermatan sulfate. in contrast, a. nigra dermatan sulfate, also enriched in 2-o-sulfated a-l-iduronic acid, but in this case sulfated at o-6 of the n-acetyl-b-d-galactosamine units, has no in vitro or in vivo anticoagulant activity, does not prevent thrombus formation but shows a bleeding effect similar to the mammalian glycosaminoglycan. ascidian heparin, composed by 2-o-sulfated a-l-iduronic acid, n- and 6-o-sulfated glucosamine (75%) and a-l-iduronic acid, n- and 6-o-sulfated glucosamine (25%) disaccharide units has an anticoagulant activity 10 times lower than the mammalian heparin, is about 20 times less potent in the inhibition of thrombin by antithrombin, but has the same heparin cofactor ii activity as mammalian heparin.
