Florística e fitossociologia em parcelas permanentes da Mata Atlântica do sudeste do Brasil ao longo de um gradiente altitudinal

This paper summarizes floristic and phytossociology data of 11, out of 14 plots of 1 ha, allocated along an altitudinal gradient in the Serra do Mar, Silo Paulo, Brazil. The study was conducted at Serra do Mar State Park and the plots start at the sea level (10 m - plot of Restinga Forest that occurs at Praia da Fazenda, Picinguaba, municipality of Ubatuba) up to 1100 m above sea level (the Montane Ombrophilous Dense occurs alongside the Itamambuca Trail, municipality of Silo Luis do Paraitinga). The Restinga Forest occurs in Pleistocenic Coastal Plain where the soil is classified as a sandy Quartzipsamment (Quartzenic Neosol), while along the slopes of the Serra do Mar, the Ombrophylus Dense Forest grows on the top of a pre-Cambrian crystalline basement with granitic rocks, where the soil is a sandy-loam Dystrophic Inceptisol (Cambisol/Latosol). In all 14 plots soils are acidic (pH 3 - 4), chemically poor, with high dilution of nutrients and high saturation of aluminum. In the Restinga and at the foot of the slope the climate is Tropical/Subtropical Humid (Af/Cfa), with no dry season, an average annual rainfall over 2,200 mm and an average annual temperature of 22 degrees C. Towards the top of the Serra do Mar there is a gradual cooling along the slope, but there is no reduction in rainfall, so at 1,100 m above sea level the climate is classified as Humid Subtropical (Cfa/Cfb), with no dry season and an average annual temperature of 17 degrees C. It is important to remark that, almost daily, from 400 m above sea level up to the top of slopes the mountains are covered by a dense fog. In the 14 plots 21,733 individuals with DBH >= 4.8 cm, including trees, palms and ferns, were marked, measured and sampled. The average number of individuals sampled in each plot was 1264 ind.ha(-1)(+/- 218 SE 95%). Within the parameters considered trees prevailed (71% in the Montane ODF to 90% in the Restinga Forest), followed by palms (10% in the RF and 25% in the Montane Ombrophilous Dense Forest/ODF) and ferns (0% % in the RF and 4% in the Montane ODF). Regarding these proportions the Exploited Lowlands ODF differs from the others with only 1.8% of palm trees and striking 10% of ferns. The forest canopy is irregular with heights ranging from 7 to 9 m, rarely emergent trees reach 18 m, and due to this irregularity of the canopy the amount of light that gets through sets conditions for the development of hundreds of epiphytic species. Aside from Montana ODF, where the number of dead trees was more than 5% of individuals sampled, in the other phytophysiognomies this value was below 2.5%. In the 11 plots where the floristic study was conducted we found 562 species in 195 genera and 68 families. Only seven species - Euterpe edulis Mart. (Arecaceae), Calyptranthes lucida Mart. ex DC. and Marlierea tomentosa Cambess (both Myrtaceae), Guapira opposita (Veil.) Reitz (Nyctaginaceae), Cupania oblongifolia Mart. (Sapindaceae), Cecropia glaziovii Snethl. and Coussapoa microcarpa (Schott) Rizzini (both Urticaceae) - occurred from Restinga to Montane ODF, while 12 other species did not occur only in the Restinga Forest. Families with the greatest number of species are Myrtaceae (133 spp), Fabaceae (47 spp), Rubiaceae (49) and Lauraceae (49) throughout the gradient and Monimiaceae (21) specifically in portions Montane ODF. Only in the F plot, where logging has occurred between 1950 and 1985, the abundance of palm trees has been replaced by Cyatheaceae. The study shows a peak of diversity and richness, Shannon-Weiner index (H') ranging from 3.96 to 4.48 nats.ind(-1), in the intermediate altitudes (300 to 400 m) along the slope. Several explanations for this result are raised here, including the fact that these elevations are within the limits expansions and retractions of the different phytophysiognomies of the Atlantic ODF due to climate fluctuations during the Pleistocene. The results presented in this paper demonstrate the extraordinary richness of tree species of the Atlantic Rainforest from the northeastern coast of the State of São Paulo, reinforcing the importance of its conservation throughout the altitudinal gradient. The richness of this forest justifies a long term commitment to study its dynamics and functioning through permanent plots, and monitor the impacts of climate change in this vegetation.

Concentração de flúor e solubilidade em esmalte de dentes decíduos permanentes jovens após aplicações tópicas de soluções fluoretadas.

The aim of this article was to compare, through the distillation method, the incorporated amount of fluoride and the reduction of solubility in the enamel of both deciduous and young permanent teeth, following topical application of a 2% neutral sodium fluoride solution, according to the Knutson's technique and a 1.23% of acidulated solution, according to the Wellock & Brudevold's technique. The greatest fluoride incorporation was observed in the deciduous teeth after the usage of the 2% neutral solution. The amount of calcium and phosphorus liberation by the acid solution was greatest in the control group, followed by the group of teeth treated in acidulated solution and, finally, by those treated in 2% sodium fluoride solution.

A mediação da informação nos arquivos permanentes: serviços de referência arquivística no ambiente digital

Information Science has for its object of study the general properties of information and analysis of their construction, communication and use processes. Organic information, one of the information types, is the one recorded in the archives, which can be split into two distinct groups based on users: current and permanent, used by administrators, historians/citizens, respectively. After defining the information behavior of each group, the articles directs the discussion to the mediation of information in the permanent archives. The interaction between user and information professionals through references services aiming the user needs is presented. In addition, the standards of archival description and the research instruments as tools to reference service are discussed. Moreover, it argues the importance of information technologies and the new possibilities for the promotion of organic information in permanent archives, especially concerning the information architecture of websites and the conversion of the DTD standards of archival descriptions.

Estudo biométrico das furcas radiculares vestibular, mesial e distal dos primeiros e segundos molares superiores permanentes de humanos

Foram analisados 100 dentes primeiros molares e 100 dentes segundos molares superiores, direitos e esquerdos, permanentes, extraídos de humanos, com o objetivo de explorar a região anatômica da furca, mais especificamente realizar medidas das distâncias das aberturas das furcas vestibular, mesial, e distal até à junção esmalte-cemento, e das distâncias das referidas aberturas até às faces radiculares pertinentes: vestibular, mesial, distal e lingual. Utilizou-se para mensuração um microcomputador 486 DX-66Mhz, no qual estava instalado um software analisador de imagens Mocha-Jandel Scientific SigmaScan Pro, version 2.0. Em relação às distâncias das aberturas das furcas até à junção esmalte-cemento foi observado que as distâncias médias para a furca vestibular foram de 3,50mm e 3,03mm; para a furca mesial de 4,44mm e 4,69mm; para a furca distal de 4,26mm e 3,73mm, respectivamente para os primeiros e segundos molares superiores. Em relação às distâncias das aberturas das furcas até às faces radiculares pertinentes foi observado que as distâncias médias da furca vestibular até à face mesial da raiz mesio-vestibular foram de 3,78mm e 3,72mm; da furca vestibular até a face distal da raiz disto-vestibular 3,62 e 3,64mm; da furca mesial até à face vestibular da raiz mesio-vestibular 7,33mm e 6,89mm; da furca mesial até a face lingual da raiz lingual de 4,13mm e 4,33mm; da furca distal até à face vestibular da raiz disto-vestibular de 5,61mm e 5,09mm; da furca distal até a face lingual da raiz lingual de 4,73mm e 4,65mm, respectivamente para os primeiros e segundos molares superiores.

Seqüelas em dentes permanentes após trauma nos predecessores decíduos e sua implicação clínica

In regarding to the high prevalence of traumatic dental injuries in primary teeth and the possible disturbances on developing permanent successor germs, an early diagnosis and an adequate establishment of treatment planning are very important to minimize the damage caused by the trauma. Sequelaes can affect the coronal portion (white or yellow-brown discoloration associated or not with enamel hipoplasia, dilacerations of the crown), the root portion (dilaceration, duplication or cessation of root formation) or the whole successor permanent tooth (odontoma sequestration or disturbances of permanent successor eruption). The aim of this study is to make a literature review of the developmental disturbances of permanent teeth followed by traumatic injuries to theirs primary predecessors and to present cases reports to advise the dentists, their patients and parents about the damage that developing permanents teeth can undergo.
