    This work intends to investigate the role of myths, symbols, and rites in the dynamics of human communities, focusing, in principle, on the point of view of cultural anthropology. In development, it will seek to dialogue with analytical psychology, particularly in dealing with the relationship between rituality and transcendence, symbolic life and spirituality. As a symbol of transformation, from the Jungian perspective, it will address the mass. Finally, it intends to place the contemporary human in the field of the imaginary and make considerations about the consequences of the disappearance of rituals in today’s communities.Este trabalho pretende investigar o papel dos mitos, dos símbolos e dos ritos na dinâmica das comunidades humanas, atendo-se, em princípio, ao ponto de vista da antropologia cultural. No desenvolvimento, buscará dialogar com a psicologia analítica, particularmente no trato da relação entre ritualidade e transcendência, vida simbólica e espiritualidade. Como símbolo de transformação, na perspectiva junguiana, abordará a missa. Por fim, pretende situar o humano contemporâneo no campo do imaginário e tecer considerações sobre as consequências do desaparecimento dos rituais nas comunidades hodiernas

    Para a realização desse estudo foram considerados alguns elementos do clima, como temperatura, precipitação, evapotranspiração e índice hídrico do município de Itapetinga - BA, no período de 1961 a 1990. O objetivo foi de analisar as variações climáticas do município com uma perspectiva de compreender o comportamento do clima local e seus possíveis efeitos na região e, também, fornecer subsídios para planejamento regional. Foram utilizados dados meteorológicos do Instituto Nacional de Meteorologia (INMET), com um recorte temporal dos anos de 1961 a 1990. Com os resultados obtidos conclui-se que, o município que possui um clima que varia de semiárido a úmido, apresenta temperaturas que oscilaram entre 19,9ºC e 25,3ºC. O índice de evapotranspiração foi superior à precipitação, com exceção do mês de novembro. O município apresenta déficit hídrico com grande variabilidade, principalmente dos meses de julho para setembro. Devido as características climáticas do município de Itapetinga torna-se necessário medidas mitigadoras que levem em consideração os aspectos do clima local e, também, no que tange a planejamentos ambientais, disponibilidade hídrica, produção agrícola e, principalmente, nas tomadas de decisões

    The lipase kinetic resolution (KR) of aryloxy-propan-2-yl acetates, via hydrolysis, produced enantiomerically pure/enantioenriched mexiletine intermediates and analogs. Racemic acetates rac-1-(2,6-dimethylphenoxy)propan-2-yl acetate (rac-5a), rac-1-(2,4-dimethylphenoxy)propan-2-yl acetate (rac-5b), rac-1-(o-tolyloxy)propan-2-yl acetate (rac-5c) and rac-1-(naphthalen-1-yloxy)propan-2-yl acetate (rac-5d) were used as substrates. A preliminary screening (24 h, phosphate buffer pH 7.0 with 20% acetonitrile as co-solvent, 30 °C and enzyme:substrate ratio of 2:1, m:m) was carried out with twelve lipases using acetate 5a as substrate. Two enzymes stood out in the KR of 5a, the Amano AK lipase from Pseudomonas fluorescens and lipase from Thermomyces lanuginosus (TLL) immobilized on Immobead 150. Under these conditions, both the (R)-1-(2,6-dimethylphenoxy)propan-2-ol [(R)-4a] and the remaining (S)-1-(2,6-dimethylphenoxy)propan-2-yl acetate [(S)-5a] were obtained with enantiomeric excess (ee) > 99%, 50% conversion and enantiomeric ratio (E) > 200. The KR study was expanded to racemic acetates 5b-d, leading to the corresponding chiral remaining acetates with ≥95% ee, and the alcohols 4b-d with ≥98% ee, and conversion values close to 50%. The best conditions for KRs of rac-5b-d involved the use of lipase from P. fluorescens or TLL immobilized on Immobead 150, 24 or 48 h and 30 °C. These intermediates had their absolute configurations determined using 1H NMR spectroscopy (Mosher’s method), showing that the KRs of these acetates obeyed the Kazlauskas’ rule. Molecular docking studies corroborated the experimental results, indicating a preference for the hydrolysis of (R)-5a-d
