O reuso de águas residuais como meio de convivência com a seca no semiárido do Nordeste Brasileiro

Segundo o Atlas dos desastres naturais do Brasil, as secas e estiagens são o tipo de desastre mais recorrente no país, responsável por 54% do total de desastres registrados, sendo a região Nordeste a mais afetada. Com o problema da carência hídrica nesta região do país, torna-se fundamental utilizar a água racionalmente e priorizar formas sustentáveis para o seu reaproveitamento. Nesse contexto, este trabalho tem por objetivo principal apontar as vantagens das ações de reuso de águas de esgoto no semiárido brasileiro, destacando as práticas mais adequadas e viáveis à região, tomando por base experiências já existentes em áreas semelhantes e suas possíveis aplicações no município de São Fernando/RN. Através da pesquisa documental e de campo, pode-se afirmar que no município de São Fernando/RN, as duas ETEs, que realizam tratamento do tipo secundário e se encontram em perfeito estado de funcionamento, podem servir de fonte de água para irrigação de alimento animal bem como para arborização urbana

Avaliação da qualidade de vida de pacientes com e sem úlcera venosa

OBJETIVOS: comparar la calidad de vida de pacientes con enfermedad venosa crónica con y sin úlcera e identificar cuales los aspectos más afectados. MÉTODO: estudio con diseño trasversal y muestra de 204 pacientes con enfermedad venosa crónica. La calidad de vida fue evaluada mediante el cuestionario SF-36. Para comparar los scores entre los grupos, fue utilizada la prueba Mann-Whitney, considerando diferencia estadísticamente significativa para pOBJETIVOS: comparar a qualidade de vida de pacientes com doença venosa crônica com e sem úlcera e identificar quais os aspectos mais afetados.

Quality of life assessment of patients with and without venous ulcer

OBJECTIVES: to compare the quality of life of patients with chronic venous disease with and without ulcer and to identify the most affected aspects.METHOD: cross-sectional study with a sample of 204 patients with chronic venous disease. The quality of life was assessed with the help of the SF-36 questionnaire. To compare the scores between the groups, the Mann-Whitney test was used, considering a statistically significant difference when p<0.05.RESULTS: the quality of life score of patients with ulcer was lower when compared to that of patients without ulcer, in all domains and dimensions of the SF-36, particularly in the domains physical aspect and functional capacity, with very low scores.CONCLUSION: all aspects of quality of life were more compromised in people with ulcers. These findings can contribute towards a better understanding of the effects of chronic venous disease on the quality of life and towards a better orientation of therapeutic interventions in this population

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
