13. Práticas do Psicólogo em Instituições Públicas de Saúde: o cuidado para com outro. / Psychologists Practice in the public health institutions: the care for the other
The psychologist takes up the challenge of fitting into the public health services, more precisely into the general non-psychiatric institutions characterized as an specific locus of practice and comprehension of the issues related to the continuum health-illness. However, acting on the complex field of collective health imposes to this professional a review

14. Avaliação da dureza Knoop de compositos restauradores odontologicos fotoativados por diferentes metodos
Nowadays, the photoactivated composites are the most used esthetic restorative dental materials in dentistry. The advantages of these materials are the control of setting time and esthetic characteristics. Besides that, it?s unnecessary to prepare retentive cavity. Composites shrink during the polymerization reaction and a tension can be induced on restorati

15. Environmental color affects Nile tilapia reproduction
We investigated the effects of environmental color on the reproductive behavior of Nile tilapia, Oreochromis niloticus. Two environmental colors were tested by covering the aquarium (60 x 60 x 40 cm) with white (12 groups) or blue (13 groups) cellophane and observing reproductive behavior in groups of 2 males (10.27 ± 0.45 cm) and 3 females (10.78 ± 0.45 c

16. Context-free adaptive grammars with appearance checking. / Gramáticas livres de contexto adaptativas com verificação de aparência.
This work introduces and describes the formalism of the context-free adaptive grammar with appearance checking. Such gramatical devices have as its kernel a subjacent context-free grammar and, as mechanism of self-modification, one or several adaptive functions which determines the productions able to be applied at each step of a derivation. The appearance c

17. Estudo da instantaneização de misturas contendo cacau em po por aglomeração com jato de vapor
The agg1omeration process of dry mixtures containing cocoa powder was considered in order to evaluate the instant properties of the product. A pilot-plant steam jet agg1omerator was developed, composed by a stainless steal tower (diameter: 0.30m; height: 2.15m), a vibrating feeder for the powder supply (up to 65 kg/h), a steam generator, a device to promote

18. Tendencia da morbi-mortalidade por doença respiratoria na população idosa : o impacto da vacinação contra influenza no Estado de São Paulo e região de Botucatu
During the last decades respiratory diseases OOve increased their importance in morbid mortality ofthe elderly Brazilian population. This study OOs aimed to analyze the tendency of mortality by respiratory infections among elderly people resident in the state of Sao Paulo and in the region of Botucatu - DIR XI, in the period of 1980 to 1998, by means of mort

19. Emulating biology: Building nanostructures from the bottom up
The biological approach to nanotechnology has produced self-assembled objects, arrays and devices; likewise, it has achieved the recognition of inorganic systems and the control of their growth. Can these approaches now be integrated to produce useful systems?

20. Benthic–pelagic links and rocky intertidal communities: Bottom-up effects on top-down control?
Insight into the dependence of benthic communities on biological and physical processes in nearshore pelagic environments, long considered a “black box,” has eluded ecologists. In rocky intertidal communities at Oregon coastal sites 80 km apart, differences in abundance of sessile invertebrates, herbivores, carnivores, and macrophytes in the low zone wer

21. Contextual influences in V1 as a basis for pop out and asymmetry in visual search
I use a model to show how simple, bottom-up, neural mechanisms in primary visual cortex can qualitatively explain the preattentive component of complex psychophysical phenomena of visual search for a target among distracters. Depending on the image features, the speed of search ranges from fast, when a target pops-out or is instantaneously detectable, to ver

22. An automated multiplex oligonucleotide synthesizer: development of high-throughput, low-cost DNA synthesis.
An automated oligonucleotide synthesizer has been developed that can simultaneously and rapidly synthesize up to 96 different oligonucleotides in a 96-well microtiter format using phosphoramidite synthesis chemistry. A modified 96-well plate is positioned under reagent valve banks, and appropriate reagents are delivered into individual wells containing the g

23. Mutations Affecting Light Regulation of Nuclear Genes Encoding Chloroplast Glyceraldehyde-3-Phosphate Dehydrogenase in Arabidopsis1
Expression of nuclear genes that encode the A and B subunits of chloroplast glyceraldehyde-3-phosphate dehydrogenase (GAPA and GAPB) of Arabidopsis is known to be regulated by light. We used a negative selection approach to isolate mutants that were defective in light-regulated expression of the GAPA gene. Two dominant mutants belonging to the same complemen

24. Positioning protein molecules on surfaces: A nanoengineering approach to supramolecular chemistry
We discuss a nanoengineering approach for supramolecular chemistry and self assembly. The collective properties and biofunctionalities of molecular ensembles depend not only on individual molecular building blocks but also on organization at the molecular or nanoscopic level. Complementary to “bottom-up” approaches, which construct supramolecular ensembl
