Com o objetivo de estudar alguns aspectos relacionados à dormência das sementes de trapoeraba (Commelina benghalensis L.), dois experimentos foram conduzidos em condições de laboratório. No primeiro experimento, realizado em 1989, utilizaram-se sementes aéreas e subterrâneas oriundas de Paranavaí-PR e apenas sementes aéreas oriundas de Jaboticabal-SP, todas recém-colhidas, nas modalidades de grandes e pequenas (separadas de acordo com seu peso). Os tratamentos de quebra de dormência foram. escarificação mecânica com lixa; escarificação química com ácido sulfúrico; choque térmico úmido; choque térmico seco, além da testemunha. No segundo experimento, realizado em 1990, utilizaram-se sementes do mesmo lote do experimento anterior, após um ano de armazenamento em câmara a 10o C, sem qualquer tratamento de semente, visando verificar a germinação das sementes. Os resultados indicaram que: 1) o ácido sulfúrico foi o tratamento que proporcionou as maiores porcentagens de germinação (P.G.) e os maiores índices de velocidade de germinação (I.V.G.) em todos os tipos de sementes estudadas; 2) a P.G. e o I.V.G. das sementes recém-colhidas aumentam após um ano de armazenamento; 3) as sementes grandes apresentam maior P.G. e maior I.V.G. que as sementes pequenas; 4) as sementes colhidas em Paranavaí, apresentaram uma tendência de maior P.G. e maior I.V.G. que as colhidas em Jaboticabal.

O artigo aborda as relações entre a Psicologia e a Educação, tomando especialmente a perspectiva psicogenética, cujas teorias enriquecem tanto a Psicologia quanto a Educação. Apresenta, inicialmente, breve histórico dos estudos psicológicos do desenvolvimento humano, salientando as várias fases pelas quais se constituiu a Psicologia do Desenvolvimento. Trata, em seguida, das idéias centrais da teoria psicogenética piagetiana e de suas vertentes funcionalista e sócio-interacionista e comenta, por fim, a tendência das pesquisas sobre os conhecimentos sociais e conteúdos escolares, levantando suas contribuições para a educação escolar.

O presente artigo discute os sentidos da filiação para crianças abrigadas, vítimas de violência doméstica. O desejo dessas crianças de recuperar a filiação familiar é analisado como busca de um lugar psicossocial. As crianças abrigadas, que sofreram uma ruptura na filiação primeva e história de vida, flutuam entre vinculações efêmeras, sem referências de seu passado e sem pontos fixos e sólidos para seu assentamento no presente que lhes possam servir de guia ou de novas filiações. Tal condição de desfiliação é focalizada como tendência da sociedade contemporânea em afrouxar vinculações, movimentar os ancoradouros psicossociais e produzir desterritorializações, favorecendo uma subjetividade móvel, não identitária, desenlaçada de encaixes e conexões duradouros. Como conclusão, é apontada a continuidade histórica da vitimização da infância realizada pela condição de trânsito e passagem na qual vive, impeditiva de constituições de vínculos duradouros e sólidos que permitam uma suficiente estabilidade e segurança para a prospecção do mundo.

The immunological reply of a population to an infectious agent can vary between races and handling of this population. Regional research becomes important, in order to know the interrelation between the agent and its host. In this way, the occurrence of immunoglobulins of class G, anti-Babesia bovis and anti-Babesia bigemina in the Nelore (Bos indicus) and Hostein breed (Bos taurus), was investigated in two regions of the State of São Paulo, 300 km distant from each other. For the indirect method of ELISA, 1, 161 bovine serum samples were tested. The medium frequencies of antibodies showed that in the two regions exists an enzootic stability for B. bovis in both breeds studied; even so there was a tendency of marginal area for the Nelore breed in one of the regions. Regarding B. bigemina, in both regions exists enzootic stability for the Hostein and enzootic instability for the Nelore breed. Therefore, acute cases of the disease or specific outbreaks by B. bigemina infection in the Nelore breed may occur in these regions.

Nosocomial infections with Candida species are recognized as a significant cause of morbidity and mortality in both seriously ill immunocompetent and immunocompromised patients. Infections with Candida albicans and non-albicans Candida species have become a significant cause of infection in humans. Several of the more commonly Candida spp isolates are less susceptible to the antifungal drugs currentlly applied in clinical treatment, a factor that means significant difficulties for effective treatment. The modern mycology laboratory has an important role to play in several aspects relating to these organisms, including therapy, detection, identification and epidemiological analysis. In this study, we have provided an initial comparison of differences in species distribution among Candida isolates from four general hospitals of São Paulo,SP. Overall, 40 isolates of C. albicans, C. parapsilosis and C. tropicalis were isolated respectively in 35%, 50% and 15%, revealed a tendency of higher frequency of non-albicans species. The species distribution in patients with candidemia showed that the most commonly species were C. parapsilosis (45,4%), followed by C. albicans (36,4%) and C. tropicalis (18,2%); thus, we have an increase of non-albicans species. The three different species were include in 6, 3, and 4 different biotypes, respectively C. albicans, C. parapsilosis e C. tropicalis. This study emphasizes the importance of periodic evaluation of Candida species distribution especially in centers caring for patients at risk.

The objective of this study was determine the spatial distribution of genotypes of Terminalia argentea Mart et Suce. (Capitão-do-campo) in a natural population, aiming to outline strategy to genetic conservation in situ and ex situ. The population (Terminalia argentea) is located in an area of cerrado on the Teaching and Research Farm of FEIS / UNESP. It was sampled seeds in 30 trees to determine the biochemistry and technological traits. The trees were also located per GPS apparatus, with objective of obtaining geographic coordinate and to analysis the genotype spatial structure from I Moran Index. The analysis of spatial autocorrelations, from I Moran index, indicated the tendency of a larger structure among trees near spatially. In another hand, trees distant spatially showed smaller similarity. The spatial structure was more visible in a ray of 353m.

The aim of the study was to evaluate the effects of the inclusion of different levels of turnip cake (TNF) on the chemical composition, digestibility and quality of elephant grass silage. Due to the quality of the oil extracted from the seeds, the turnip is being considered as an important option for the biodiesel industry in Brazil. The turnip cake is obtained from the mechanical pressing of the seeds to produce oil, and it differs from the meal by the content of fat. In the meal the fat is less than 1%, due to the use of solvents for the oil extraction. Experimental silos were used in a completely randomized design, in factorial arrangement 2 x 3 (two types of material and four levels of inclusion). The materials were represented for original material (fresh) and ensiled material, with four levels of inclusion of TNF (0, 3, 6, and 9%). Dry matter (DM), ether extract (EE), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), nitrogen indigestible neutral detergent (NIDN), nitrogen indigestible acid detergent (NIDA), ash (MM), lignin (LIG), buffer power (PT), calcium (Ca), phosphorus (P) and in vitro dry matter digestibility (IVDDM) were determined in all materials. In silage, additionally, were determined pH and amoniacal nitrogen (NH3-N). There were effects of inclusion of TNF and the type of material on the DM, CP, ADF, NIDA, P, and MM contents and on IVDDM. The interaction of the two factors was observed to the contents of CP, NDF, ADF, NIDA, Ca and IVDDM. In silage, the DM levels were lower (P < 0.05) than in original material. The values of DM were increased linearly as increased levels of inclusion of TNF. The fibrous components, including NIDN and NIDA, decreased linearly when the TNF increased. In all treatments, values of pH and N-NH3 considered ideal for good silage were observed. The IVDDM was reduced, linearly, with the addition of increasing levels of TNF. A negative correlation (-0.95) between IVDDM and content of EE may explain the tendency of this variable, due to the EE content increased linearly with the addition of TNF. The addition of TNF as an additive in silage of elephant diminished IVDDM. Considering the changes observed in the chemical composition and digestibility of elephant grass silage with TNF as additive, suggests that this should not be included at levels exceeding 3%. On the other hand, the silages with TNF as additive showed appropriate fermentation characteristics.

This work analyses the recuperation of the energy of Municipal Solid Waste (MSW) through the incineration process. It considers the up to date tendency of segregation (separation) of plastic, paper and cardboard, glass and metals and their influence in the fluxes of mass and energy in the incineration system of MSW. For its development was used information related to the generation of MSW in Bauru city and the Combust software. The results so obtained allowed the estimation of the Caloric power of the typical MSW and also of this residue when one considers the separations of paper/cardboard and plastic for recycling.
