Abstract: the objective of this study was to estimate the richness and the diversity of fruit tree species cultivated in boa vista's home gardens, as well as to determine what species the local urban population prefers. two neighborhoods that originated during the city's expansion in 1982 were sampled: (1) best - bairro dos estados (north zone) and (2) basa - bairro asa branca (west zone). seven hundred and twenty-two home gardens were surveyed in best (march 6 to 22, 2004), and 339 in basa (april 7 to july 1, 2004). thirty-six species (19 botanical families) were observed in best, and 37 (20 families) in basa, totaling 43 species (20 families). thirty species (69.8%) in 19 families (95%) occurred in both neighborhoods, suggesting common fruit preferences. the three largest indices of preference value (ivp) were coconut (cocos nucifera l. - best: 19.4% and basa: 20.5%), mango (mangifera indica l. - best: 14.9% and basa: 22.5%) and rose-apple (syzygium malaccence (l.) merr. & l.m. perry - best: 10.5% and basa: 10.1%). all of them are exotic (originating in southeast asia) and together had ivps of 44.9% (best) and 53.0% (basa). these results suggest that the cultivation of fruit trees in the home gardens of boa vista shows a pattern that concentrates choices in a few non-amazonian species that are traditionally preferred because of their successful fruit production.

Abstract: intravenous therapy (ivt) is an important item among the necessary technologies for the survival of high-risk new-born babies. however, it is also a source of pain, stress and risk of serious complications. this article aims to assess the meanings of ivt as ascribed by care teams and to discuss the reflection of such meanings on the attention to new-born babies. the article, with a theoretical referential in cultural anthropology, presents an ethnographic case study carried out in a neonatal intensive care unit of municipal administration in rio de janeiro. subjects were nine nurses, four doctors, and three nurse assistants. data collection was carried out with a semi-structured interview and participative observation. the qualitative analysis was performed using the method of interpretation of the senses. meanings, interweaved with the cultural network, showed that ivt practice is often reduced to peripheral puncture techniques, bringing on a series of complications for high risk new-born babies and intense emotional waste for the professional team and the family. re-signification of ivt practice will only be possible with a critical analysis of the cultural patterns it is now based on.

Abstract: this work analyzes occupational stress in 155 health professionals (example: doctors and nurses) from hospitals and health care centres in the north of portugal. we evaluated the following variables: stress, burnout, proactive coping, organizational commitment and satisfaction/professional fulfilment. results revealed significant stress experiences in 15% of the professionals and emotional exhaustion problems in 6%. comparative analysis (manova and t-test for independent samples) suggested a higher tendency to experience occupational stress in the following groups: a) females (although males showed more depersonalization problems); b) younger and less experienced professionals; c) single persons; d) nurses practitioners; e) professionals that worked in health care centres; f) those professionals with short-term working contracts; and g) the professionals working on a shift-basis system. at the end, we discuss some of the implications for future research of the present study.
A study of the sequential Michael addition-ring closure reaction of ethyl acetoacetate with chalcone: influence of quaternary ammonium cations as phase transfer catalysts
Lopes, Regina C. V.;Oliveira, Maria da Concei??o F. de;Lemos, Telma L. G. de;Mattos, Marcos C. de;
Journal of the Brazilian Chemical Society , 2005, DOI: 10.1590/S0103-50532005000600023
Abstract: the michael addition of ethyl acetoacetate 1 to chalcone 2 under solid/liquid phase transfer catalysis (sl-ptc), solvent free, afforded michael adduct 3 and an annulated compound 4 in good yield. the cyclic compound 4 was obtained in the majority via an annulation process of the michael adduct 3. the proportion of 4 in the ratio of 3/4 was dependant on the structure of the quaternary ammonium cation. the results were interpreted on the basis of the organophilicity and accessibility of the catalysts as well as by invoking a 6-membered ring transition state for the formation of 4 due to the chelation level with q+.
