The present study was undertaken to determine the importance of socioeconomic factors (family income), urban or rural family location, parity, maternal age, the presence of maternal and fetal pathologies as well as placental abnormalities on the weight and gestational age of 566 newborns. The highest incidence of newborns with low birth weight for gestational age was significantly more frequent in urban populations when the mothers were from low socio-economic levels. In mothers from low socioeconomic levels infants with low birth weight for gestational age were seen in greater proportion among primaparas and had a tendency to be higher in mothers aged less than 20 years; prematurity was highest in mothers ≥ 30 years old and significantly higher from the 8th gestation on. Maternal and fetal pathologies emphasized these characteristics and placental pathologies were not correlated with the distribution of weight and length of gestation. In mothers of high socioeconomic levels age and parity were not correlated with weight and gestational age of the newborns.

160 groundwater bores in the Ribeirao Preto region were used to study the behaviour of the piezometric surface of the Botucatu Formation aquifer by geostatistical methodology. The semi-variogram showed the following results: nugget = 50 m2; sill = 450 m2 and range = 4.5 km. The piezometric surface, obtained by punctual kriging in a 100 x 100 knot grid, revealed two lowered zones: one in a southwest to north-northeastern trend, indicating the groundwater flow north toward the Rio Pardo; and the other in the central part due to the high concentration of holes in the urban region of Ribeirao Preto city. -from English summary

The objective of this study was to determine the influence of five different water levels on the crop development of Calla. The crop parameters evaluated were leaf area and evapotranspiration. The study was conducted in glass greenhouse with 50% of sunlight reduction. The plants were grown in PVC pots with 150 mm diameter, which were filled with substrate. The plant tubers weighed from 10 g to 12 g. The pots were placed within containers, under water level constant automatically.. The table water levels used were 10, 17, 24, 31 and 38 cm. Nine evaluations during the growth cycle checked the growth development. The evaporation varied from 26.89 to 46.14 L.plant-1 for 38 and 10 cm water levels, respectively and leaf area per plant showed 1011.6 to 2016.3 for the same levels. The substrate water was more available in the treatment 24 cm, with more restrictions in the upper and lower treatments. There was positive correlation between leaf area and evapotranspiration at the final of the culture.

Este trabalho mostra os resultados obtidos com ensaios geofísicos realizados no Município de Rio Claro (SP) para mapear o lençol freático e delimitar as possíveis áreas de recarga e descarga do Aqüífero Rio Claro. Para tanto, utilizou-se um grande número de ensaios geofísicos, uma vez que não seria adequado gerar um mapa potenciométrico com o pequeno número de poços existentes na área. Os ensaios geofísicos foram executados pelo método de eletrorresistividade, utilizando-se da técnica de sondagem elétrica vertical (SEV) com arranjo Schlumberger. A superfície do lençol freático, na área de estudo, constituída pela Formação Rio Claro, composta de sedimentos arenosos com intercalações de camadas centimétricas argilosas, está situado entre as cotas 566 e 669 m. O fluxo das águas subterrâneas é orientado a partir das cotas altas (norte da área) para as cotas baixas (sul e sudoeste da área) e acompanha, grosso modo, a topografia local. Palavras-chave: Geofísica Aplicada, eletrorresistividade, sondagem elétrica vertical, mapa potenciométrico, Aqüífero Rio Claro.

The rehabilitation with mandibular distal extension removable partial dentures (DERPD) is complex and the use of implants has been improving the functioning of this approach. The insertion bony level around of the last support tooth is an aggravating factor, since it can harm the longevity of the treatment. Thus, the aim of this research was to evaluate the displacement tendency of a mandibular DERPD associated to an implant, with different insertion bony levels and different connections between the RPD and the support tooth, by finite element analysis. Eight models were made: MA - DERPD, incisal rest, no bony loss; MB - DERPD, distal plate, no bony loss; MC - DERPD, incisal rest, no bony loss, with implant and ERA system; MD - DERPD, distal plate, no bony loss, with implant and ERA system; ME - DERPD, incisal rest, bony loss; MF - DERPD, distal plate, bony loss; MG - DERPD, incisal rest, bony loss, with implant and ERA system; MH - DERPD, distal plate, bony loss, with implant and ERA system. Loads of 50 N in each peak were applied. Displacement maps were obtained and showed that implant favors this association and the bony loss harms the prognostic of the prosthesis. It is concluded that: the introduction of the implant with ERA system reduced the displacement tendency of the tooth and supporting structures; introduction of distal plate reduced the movement tendency of the support tooth; the decrease of the periodontal support didn't influence significantly the displacement tendency of the models with distal plate distal, but it influenced the models with distal incisal rest.
