Construção de um Vê de Gowin para análises de produções acadêmicas de Enfermagem

O artigo apresenta uma ferramenta da Aprendizagem Significativa denominada V de Gowin e a possibilidade de seu uso em um processo de desempacotamento de produções acadêmicas de Enfermagem. Objetiva construir uma proposta de alteração da ferramenta com a utilização dos elementos que compõem a trajetória processual da Teoria da Intervenção Práxica da Enfermagem em Saúde Coletiva (TIPESC) e analisar uma dissertação produzida nesta área de conhecimento. Trata-se de um estudo descritivo e exploratório que apresenta o V de Gowin, propondo alterações no seu domínio metodológico. Constatou-se a possibilidade de utilização para análises de produções acadêmicas de enfermagem deste instrumento heurístico que já se mostrou útil para apoiar processos de ensino e aprendizagem e analisar produções acadêmicas na área, pela capacidade de captar e interpretar qualquer fenômeno articulado aos processos de produção e reprodução social.

Arsenic(V) adsorption onto α-Al2O3 between 25 and 70°C

The adsorption of As(V) onto alpha -Al2O3 was investigated at 25, 50 and 70 degreesC using batch adsorption experiments. Results indicate that As is strongly adsorbed at low pH and gets progressively released to the fluid with increasing pH above 7. At any pH, increasing temperature favors aqueous species of As over surface species. Surface complexation constants were determined at the experimental temperatures by fitting the adsorption data. Adsorption reactions were then converted to semi-isocolumbic reactions, i.e, reactions with balanced like-charged aqueous species. Intrinsic adsorption constants of semi-isocolumbic reactions change linearly when plotted against inverse temperature, suggesting that the heat capacity of these reactions remains constant over the temperature range considered. This permitted thermodynamic parameters of intrinsic surface complexation constants to be determined. Changes in surface complexation constants result in a change in the surface speciation with increasing temperature. This change is similar to the one observed for aqueous species, i.e. increasing temperature favors less negatively charged species below a pH of 9 and more negatively charged species above a pH of 10. Comparison with the stability of As surface complexes with Fe suggests that surface complexes with Al are more stable. (C) 2001 Elsevier Science Ltd. All rights reserved.

The relation of body mass index and abdominal adiposity with dyslipidemia in 27 general populations of the WHO MONICA Project.

The association between adiposity measures and dyslipidemia has seldom been assessed in a multipopulational setting. 27 populations from Europe, Australia, New Zealand and Canada (WHO MONICA project) using health surveys conducted between 1990 and 1997 in adults aged 35-64 years (n = 40,480). Dyslipidemia was defined as the total/HDL cholesterol ratio >6 (men) and >5 (women). Overall prevalence of dyslipidemia was 25% in men and 23% in women. Logistic regression showed that dyslipidemia was strongly associated with body mass index (BMI) in men and with waist circumference (WC) in women, after adjusting for region, age and smoking. Among normal-weight men and women (BMI<25 kg/m(2)), an increase in the odds for being dyslipidemic was observed between lowest and highest WC quartiles (OR = 3.6, p < 0.001). Among obese men (BMI ≥ 30), the corresponding increase was smaller (OR = 1.2, p = 0.036). A similar weakening was observed among women. Classification tree analysis was performed to assign subjects into classes of risk for dyslipidemia. BMI thresholds (25.4 and 29.2 kg/m(2)) in men and WC thresholds (81.7 and 92.6 cm) in women came out at first stages. High WC (>84.8 cm) in normal-weight men, menopause in women and regular smoking further defined subgroups at increased risk. standard categories of BMI and WC, or their combinations, do not lead to optimal risk stratification for dyslipidemia in middle-age adults. Sex-specific adaptations are necessary, in particular by taking into account abdominal obesity in normal-weight men, post-menopausal age in women and regular smoking in both sexes.
