Abstract: The main goal of this research study was to establish the physicochemical characteristics of sewage sludge, and the nutrients needed to enhance the properties of soil with a view to exploiting were potential for agriculture. The example used was the cultivation of radish (Raphanus sativus). The findings are intended as a contribution towards making agriculture sustainable. This study was carried out to assess the response of radish (Raphanus sativus L.) to doses of sewage sludge applied in medium texture soils, and the socioeconomic contributions that such cultivation of radish would make. Levels of 0.25 and 75 ton/ha of sewage sludge plus the equivalent dose of 25 ton/ha of sewage sludge vermin compost by California Red were used after making a randomized experimental design with three replicates. 30 days after sowing radish seeds, the following data were collected: the number of leaves per plant (NLP); plant height (PH in cm); root diameter (RD) and tubercle production (TP ton/ha). In addition, the pH, EC-electric conductivity (EC), and soil organic matter (SOM) were determined. Statistical analysis showed that 25 and 50 tons/ha gave the best results for the parameters assessed. The estimated increase in family mean income from selling radish crops fertilized with sewage sludge is around 17%.

Abstract: one of the main problems faced by humanity is pollution caused by residues resulting from the production and use of goods, e.g, sewage sludge. among the various alternatives for its disposal, the agricultural use seems promising. the purpose of this study was to evaluate the hydraulic conductivity and interaction of soil with sandy-silty texture, classified as spodosols, from the experimental station itapirema - ipa, in goiana, state of pernambuco, in mixtures with sewage sludge from the mangueira sewage treatment station, in the city of recife, pernambuco at rates of 25, 50 and 75 mg ha-1. tests were conducted to let water percolate the natural saturated soil and soil-sludge mixtures to characterize their physical, chemical, and microstructural properties as well as hydraulic conductivity. statistical data analysis showed that the presence of sewage sludge in soils leads to an increase of the < 0.005 mm fraction, reduction in real specific weight and variation in optimum moisture content from 11.60 to 12.90 % and apparent specific dry weight from 17.10 and 17.50 kn m-3. in the sludge-soil mixture, the quartz grains were covered by sludge and filling of the empty soil macropores between grains. there were changes in the chemical characteristics of soil and effluent due to sewage sludge addition and a small decrease in hydraulic conductivity. the results indicate the possibility that soil acidity influenced the concentrations of the elements found in the leachate, showing higher levels at higher sludge doses. it can be concluded that the leaching degree of potentially toxic elements from the sewage sludge treatments does not harm the environment.

Abstract: Bacteria are abundant in soil microbiota and they are responsible for various enzymatic transformations that aid in decomposition and mineralization of several nutrients. Sewage sludge is a residue generated during biological treatment of wastewater rich in organic matter and nutrients, and it has many times in its composition pathogenic bacteria and heavy metals. Samples were collected in sewage sludge at Mangueira station, Recife (PE) for the isolation, identification, detection of enzyme (amylase and urease) in mesophilic bacteria at 28 and 37 oC and detection of heavy metals. The results showed that 28 oC had higher amounts of isolates. At both temperatures, were found pathogenic bacteria, and enzymatic assays, best results were obtained at 28 oC. The urease detection was observed at the two temperatures. It was detected the presence of heavy metals in sludge: cadmium, 2.2 ± 0.0004; zinc, 600 ± 0.01, and copper, 909.8 ± 0.001 in mg/kg respectively.

Abstract: ordinal logistic regression models have been developed for analysis of epidemiological studies. however, the adequacy of such models for adjustment has so far received little attention. in this article, we reviewed the most important ordinal regression models and common approaches used to verify goodness-of-fit, using r or stata programs. we performed formal and graphical analyses to compare ordinal models using data sets on health conditions from the national health and nutrition examination survey (nhanes ii).

Abstract: quality of life has been increasingly emphasized in public health research in recent years. typically, the results of quality of life are measured by means of ordinal scales. in these situations, specific statistical methods are necessary because procedures such as either dichotomization or misinformation on the distribution of the outcome variable may complicate the inferential process. ordinal logistic regression models are appropriate in many of these situations. this article presents a review of the proportional odds model, partial proportional odds model, continuation ratio model, and stereotype model. the fit, statistical inference, and comparisons between models are illustrated with data from a study on quality of life in 273 patients with schizophrenia. all tested models showed good fit, but the proportional odds or partial proportional odds models proved to be the best choice due to the nature of the data and ease of interpretation of the results. ordinal logistic models perform differently depending on categorization of outcome, adequacy in relation to assumptions, goodness-of-fit, and parsimony.

Abstract: Interest in quality of life in mental health care has been stimulated by the deinstitutionalization of psychiatric patients as well as a parallel interest in understanding the scope of their daily lives. This study aims to investigate the socio-demographic and clinical variables related to low quality of life, using a cross-sectional design to evaluate quality of life by means of the QLS-BR scale. We interviewed a sample of 123 outpatients from a reference mental health center in Divinópolis, Minas Gerais State, Brazil, clinically diagnosed with schizophrenia. Univariate and multivariate logistic regression analyses were carried out. The results showed that low quality of life is associated with one or more of the following: male gender, single marital status, low income plus low schooling, use of three or more prescribed psychoactive drugs, psychomotor agitation during the interview, and current follow-up care. The study identifies plausible indicators for the attention and care needed to improve psychiatric patient treatment.

Abstract: A esquizofrenia afeta desfavoravelmente a qualidade de vida dos pacientes, mas seu impacto pode variar de acordo com o sexo. Diferen as relatadas têm orientado o planejamento de interven es específicas. O objetivo deste estudo foi investigar a qualidade de vida por sexo em pacientes com esquizofrenia, explorando o domínio ocupacional. Foi conduzido um estudo transversal com pacientes em acompanhamento ambulatorial, mensurando a qualidade de vida por meio da Quality of Life Scale (QLS-BR). Compara es dos escores de qualidade de vida foram feitas, seguidas de análises multivariadas usando a árvore de classifica o (CHAID) e a regress o logística ordinal. Os resultados apontam melhor qualidade de vida para mulheres (p < 0,05). No domínio ocupacional, o estado civil apresentou-se como a variável mais relevante: mulheres e homens solteiros apresentaram baixa qualidade de vida quando comparados com os casados, respectivamente OR = 4,5 (IC95%: 1,2-16,6) e OR=10,0 (IC95%: 2,9-33,3). Dura o da doen a (> 5 anos) outro marcador importante, porém no modelo logístico esta variável associou-se à baixa qualidade de vida somente para os homens (OR = 3,2; IC95%: 1,1-9,0). Mulheres apresentaram melhor qualidade de vida, sugerindo maior envolvimento ocupacional, possivelmente resultante de uma maior demanda social e em atividades do lar.
