Entre a escola e a vida: desafios da ética de si para a experiência formativa

This essay aims to analyze the relationship between life and school. In opposition to theoretical perspectives longed for a possible reconciliation between life and school, we look for to show to existing tension between these two spheres, making an analysis of the themes of the experience with birth, death and the difference, and highlight that this reflection invites the subjects of the educational practice to an ethical attitude of care for the other, for oneself and so that the other one takes care of the care of the self. Having the thoughts of Arendt’s and Foucault’s as reference, we understand that life goes beyond school knowledge and practices, offering us what we think about educational practice and making the subjects of that practice learn how to place themselves between life and school, looking for new senses for themselves and resistance to the existent while they transform themselves. Thus, we wait to offer the educators some life problems that pervade the educational practice, reverberate in their experience and make them think about what they have left.

The Economics of Threatened Species Conservation: A Review and Analysis

Stabilizing human population size and reducing human-caused impacts on the environment are keys to conserving threatened species (TS). Earth's human population is ~ 7 billion and increasing by ~ 76 million per year. This equates to a human birth-death ratio of 2.35 annually. The 2007 Red List prepared by the International Union for Conservation of Nature and Natural Resources (IUCN) categorized 16,306 species of vertebrates, invertebrates, plants, and other organisms (e.g., lichens, algae) as TS. This is ~ 1 percent of the 1,589,161 species described by IUCN or ~ 0.0033 percent of the believed 5,000,000 total species. Of the IUCN’s described species, vertebrates comprised relatively the most TS listings within respective taxonomic categories (5,742 of 59,811), while invertebrates (2,108 of 1,203,175), plants (8,447 of 297,326), and other species (9 of 28,849) accounted for minor class percentages. Conservation economics comprises microeconomic and macroeconomic principles involving interactions among ecological, environmental, and natural resource economics. A sustainable-growth (steady-state) economy has been posited as instrumental to preserving biological diversity and slowing extinctions in the wild, but few nations endorse this approach. Expanding growth principles characterize most nations' economic policies. To date, statutory fine, captive breeding cost, contingent valuation analysis, hedonic pricing, and travel cost methods are used to value TS in economic research and models. Improved valuation methods of TS are needed for benefit-cost analysis (BCA) of conservation plans. This Chapter provides a review and analysis of: (1) the IUCN status of species, (2) economic principles inherent to sustainable versus growth economies, and (3) methodological issues which hinder effective BCAs of TS conservation.

An overview of biodiesel soil pollution: Data based on cytotoxicity and genotoxicity assessments

Biodiesel production has received considerable attention in the recent past as a nonpolluting fuel. However, this assertion has been based on its biodegradability and reduction in exhaust emissions. Assessments of water and soil biodiesel pollution are still limited. Spill simulation with biodiesel and their diesel blends in soils were carried out, aiming at analyzing their cytotoxic and genotoxic potentials. While the cytotoxicity observed may be related to diesel contaminants, the genotoxic and mutagenic effects can be ascribed to biodiesel pollutants. Thus, taking into account that our data stressed harmful effects on organisms exposed to biodiesel-polluted soils, the designation of this biofuel as an environmental-friendly fuel should be carefully reviewed to assure environmental quality.

Avaliação da qualidade do Sistema de Informação de Registro de Óbitos Hospitalares (SIS-ROH), Hospital Central da Beira, Moçambique

As informações de mortalidade são úteis para avaliar a situação de saúde de uma população. Dados de mortalidade confiáveis produzidos por um sistema de informação de saúde nacional constituem uma ferramenta importante para o planejamento de saúde. Em muitos países, sobretudo em desenvolvimento, o sistema de informação de mortalidade continua precário. Apesar dos esforços feitos em Moçambique para melhoria das estatísticas de mortalidade, os desafios ainda prevalecem em termos de tecnologias de informação, capacidade técnica de recursos humanos e em termos de produção estatística. O SIS-ROH é um sistema eletrônico de registro de óbitos hospitalares de nível nacional, implementado em 2008 e tem uma cobertura de apenas 4% de todos os óbitos anuais do país. Apesar de ser um sistema de nível nacional, ele presentemente funciona em algumas Unidades Sanitárias (US), incluindo o Hospital Central da Beira (HCB). Dada a importância deste sistema para monitorar o padrão de mortalidade do HCB e, no geral, da cidade da Beira, este estudo avalia a qualidade do SIS-ROH do HCB. É um estudo descritivo sobre a completitude, cobertura, concordância e consistência dos dados do SIS-ROH. Foram analisados 3.009 óbitos de menores de 5 anos ocorridos entre 2010 e 2013 e regsitrados no SIS-ROH e uma amostra de 822 Certificados de Óbitos (COs) fetais e de menores de 5 anos do HCB. O SIS-ROH apresentou uma cobertura inferior a 50% calculados com os dados de mortalidade estimados pelo Inquérito Nacional de Causas de Morte (INCAM). Verificamos a utilização de dois modelos diferentes de CO (modelo antigo e atual) para o registro de óbitos referentes ao ano de 2013. Observou-se completitude excelente para a maioria das variáveis do SISROH. Das 25 variáveis analisadas dos COs observou-se a seguinte situação: 9 apresentaram completitude muito ruim, sendo elas relativas à identificação do falecido (tipo de óbito e idade), relativas ao bloco V em que dados da mãe devem ser obrigatoriamente preenchidos em caso de óbitos fetais e de menores de 1 ano (escolaridade, ocupação habitual, número de filhos tidos vivos e mortos, duração da gestação) e relativas às condições e às causas de óbito (autópsia e causa intermédiacódigo); 3 variáveis apresentaram completitude ruim relativas à identificação do falecido (NID) e relativas às condições e causas de morte (causa intermédia - descrição e causa básica - código); 9 apresentaram completitude regular relativas à identificação do falecido (data de nascimento e idade), relativas ao bloco V (idade da mãe, tipo de gravidez, tipo de parto, peso do feto/bebé ao nascer, morte do feto/bebé em relação ao parto) e relativas às condições e causa de óbito (causa direta- código, causa básica descrição); 2 apresentaram completitude bom relativas à identificação do falecido (sexo e raça/cor) e, por último, 2 apresentaram completitude excelente relativas ao local de ocorrência de óbito (data de internamento e data de óbito ou desaparecimento do cadáver). Algumas variáveis do SIS-ROH e dos COS apresentaram inconsistências. Observou-se falta de concordância para causa direta entre o SIS-ROH e os COs. Conclusão: Moçambique tem feito esforços para aprimorar as estatísticas de mortalidade, porém há lacunas na qualidade; a análise rotineria dos dados pode identificar essas lacunas e subsidiar seu aprimoramento.

Comparative genomic analysis of the odorant-binding protein family in 12 Drosophila genomes: purifying selection and birth-and-death evolution

Background: Chemoreception is a widespread mechanism that is involved in critical biologic processes, including individual and social behavior. The insect peripheral olfactory system comprises three major multigene families: the olfactory receptor (Or), the gustatory receptor (Gr), and the odorant-binding protein (OBP) families. Members of the latter family establish the first contact with the odorants, and thus constitute the first step in the chemosensory transduction pathway.Results: Comparative analysis of the OBP family in 12 Drosophila genomes allowed the identification of 595 genes that encode putative functional and nonfunctional members in extant species, with 43 gene gains and 28 gene losses (15 deletions and 13 pseudogenization events). The evolution of this family shows tandem gene duplication events, progressive divergence in DNA and amino acid sequence, and prevalence of pseudogenization events in external branches of the phylogenetic tree. We observed that the OBP arrangement in clusters is maintained across the Drosophila species and that purifying selection governs the evolution of the family; nevertheless, OBP genes differ in their functional constraints levels. Finally, we detect that the OBP repertoire evolves more rapidly in the specialist lineages of the Drosophila melanogaster group (D. sechellia and D. erecta) than in their closest generalists.Conclusion: Overall, the evolution of the OBP multigene family is consistent with the birth-and-death model. We also found that members of this family exhibit different functional constraints, which is indicative of some functional divergence, and that they might be involved in some of the specialization processes that occurred through the diversification of the Drosophila genus.

Organometallic anticancer agents that interfere with cellular energy processes: a subtle approach to inducing cancer cell death.

Two hybrid compounds comprising an antimetastatic ruthenium-arene fragment tethered to an indazole-3-carboxylic acid derivative that inhibits aerobic glycolysis in cancer cells have been prepared and evaluated in a variety of cancer cell lines, including highly relevant human glioblastoma cells, with an apparent synergistic action between the two components observed.

Effects of age, birth cohort and period of death on Swiss cancer mortality, 1951-1984.

Swiss death certification data over the period 1951-1984 for total cancer mortality and 30 major cancer sites in the population aged 25 to 74 years were analysed using a log-linear Poisson model with arbitrary constraints on the parameters to isolate the effects of birth cohort, calendar period of death and age. The overall pattern of total cancer mortality in males was stable for period values and showed some moderate decreases in cohort values restricted to the generations born after 1930. Cancer mortality trends were more favourable in females, with steady, though moderate, declines in both cohort and period values. According to the estimates from the model, the worst affected generation for male lung cancer was that born around 1910, and a flattening of trends or some moderate decline was observed for more recent cohorts, although this decline was considerably more limited than in other European countries. There were decreases in cohort and period values for stomach, intestine and oesophageal cancer in both sexes and (cervix) uteri in females. Increases were observed in both cohort and period trends for pancreas and liver in males and for several other neoplasms, including prostate, brain, leukaemias and lymphomas, restricted, however, for the latter sites, to the earlier cohorts and hence partly attributable to improved diagnosis and certification in the elderly. Although age values for lung cancer in females were around 10-times lower than in males, upward trends in female lung cancer cohort values were observed in subsequent cohorts and for period values from the late 1960's onwards. Therefore, future trends in female lung cancer mortality should continue to be monitored. The application of these age/period/cohort models thus provides a summary guide for the reading and interpretation of cancer mortality trends, although it cannot replace careful inspection of single age-specific rates.

Hour of birth as a prognostic factor for perinatal death.

The analysis of the 220,540 births and 2152 perinatal deaths recorded in Switzerland between 1979 and 1981 showed a variation of perinatal mortality rates (PMR) according to the hour of birth. The PMR for babies born between 4 pm and 2 am was 12 per 1000, contrasting with a figure of 8.4 per 1000 for babies born between 2 am and 4 pm. This pattern, which was fairly constant throughout the week, was characterised by a slow and steady increase from the very early morning, reaching a maximum in the late evening. There was also an hour-to-hour variation in the proportion of babies born weighing less than 2500 g, with a maximum in the evening and a less pronounced peak in the morning: the mortality rates by birthweight were raised only in the evening. Since the availability of hospital staff and equipment also follows a circadian rhythm, the variation in PMR may be related to a circadian rhythm of quality of care or possibly to chronobiological or selection factors.

Studies on Advanced Oxidation Processes for the Removal of Acetamiprid from Wastewater

Pollution of water with pesticides has become a threat to the man, material and environment. The pesticides released to the environment reach the water bodies through run off. Industrial wastewater from pesticide manufacturing industries contains pesticides at higher concentration and hence a major source of water pollution. Pesticides create a lot of health and environmental hazards which include diseases like cancer, liver and kidney disorders, reproductive disorders, fatal death, birth defects etc. Conventional wastewater treatment plants based on biological treatment are not efficient to remove these compounds to the desired level. Most of the pesticides are phyto-toxic i.e., they kill the microorganism responsible for the degradation and are recalcitrant in nature. Advanced oxidation process (AOP) is a class of oxidation techniques where hydroxyl radicals are employed for oxidation of pollutants. AOPs have the ability to totally mineralise the organic pollutants to CO2 and water. Different methods are employed for the generation of hydroxyl radicals in AOP systems. Acetamiprid is a neonicotinoid insecticide widely used to control sucking type insects on crops such as leafy vegetables, citrus fruits, pome fruits, grapes, cotton, ornamental flowers. It is now recommended as a substitute for organophosphorous pesticides. Since its use is increasing, its presence is increasingly found in the environment. It has high water solubility and is not easily biodegradable. It has the potential to pollute surface and ground waters. Here, the use of AOPs for the removal of acetamiprid from wastewater has been investigated. Five methods were selected for the study based on literature survey and preliminary experiments conducted. Fenton process, UV treatment, UV/ H2O2 process, photo-Fenton and photocatalysis using TiO2 were selected for study. Undoped TiO2 and TiO2 doped with Cu and Fe were prepared by sol-gel method. Characterisation of the prepared catalysts was done by X-ray diffraction, scanning electron microscope, differential thermal analysis and thermogravimetric analysis. Influence of major operating parameters on the removal of acetamiprid has been investigated. All the experiments were designed using central compoiste design (CCD) of response surface methodology (RSM). Model equations were developed for Fenton, UV/ H2O2, photo-Fenton and photocatalysis for predicting acetamiprid removal and total organic carbon (TOC) removal for different operating conditions. Quality of the models were analysed by statistical methods. Experimental validations were also done to confirm the quality of the models. Optimum conditions obtained by experiment were verified with that obtained using response optimiser. Fenton Process is the simplest and oldest AOP where hydrogen peroxide and iron are employed for the generation of hydroxyl radicals. Influence of H2O2 and Fe2+ on the acetamiprid removal and TOC removal by Fenton process were investigated and it was found that removal increases with increase in H2O2 and Fe2+ concentration. At an initial concentration of 50 mg/L acetamiprid, 200 mg/L H2O2 and 20 mg/L Fe2+ at pH 3 was found to be optimum for acetamiprid removal. For UV treatment effect of pH was studied and it was found that pH has not much effect on the removal rate. Addition of H2O2 to UV process increased the removal rate because of the hydroxyl radical formation due to photolyis of H2O2. An H2O2 concentration of 110 mg/L at pH 6 was found to be optimum for acetamiprid removal. With photo-Fenton drastic reduction in the treatment time was observed with 10 times reduction in the amount of reagents required. H2O2 concentration of 20 mg/L and Fe2+ concentration of 2 mg/L was found to be optimum at pH 3. With TiO2 photocatalysis improvement in the removal rate was noticed compared to UV treatment. Effect of Cu and Fe doping on the photocatalytic activity under UV light was studied and it was observed that Cu doping enhanced the removal rate slightly while Fe doping has decreased the removal rate. Maximum acetamiprid removal was observed for an optimum catalyst loading of 1000 mg/L and Cu concentration of 1 wt%. It was noticed that mineralisation efficiency of the processes is low compared to acetamiprid removal efficiency. This may be due to the presence of stable intermediate compounds formed during degradation Kinetic studies were conducted for all the treatment processes and it was found that all processes follow pseudo-first order kinetics. Kinetic constants were found out from the experimental data for all the processes and half lives were calculated. The rate of reaction was in the order, photo- Fenton>UV/ H2O2>Fenton> TiO2 photocatalysis>UV. Operating cost was calculated for the processes and it was found that photo-Fenton removes the acetamiprid at lowest operating cost in lesser time. A kinetic model was developed for photo-Fenton process using the elementary reaction data and mass balance equations for the species involved in the process. Variation of acetamiprid concentration with time for different H2O2 and Fe2+ concentration at pH 3 can be found out using this model. The model was validated by comparing the simulated concentration profiles with that obtained from experiments. This study established the viability of the selected AOPs for the removal of acetamiprid from wastewater. Of the studied AOPs photo- Fenton gives the highest removal efficiency with lowest operating cost within shortest time.
