Persistência de mamíferos de médio e grande porte em fragmentos de floresta ombrófila mista no estado do Paraná, Brasil

The Araucaria Forest is now represented by remnants of what was a continuous area of about 200,000 km(2). Medium and large mammals inhabiting this forest have suffered the impacts from the disturbance process and environmental degradation. Thus, this study determined which medium and large mammal species still inhabit the remnants of this vegetation type in Western Parana State. Three study areas, with 520, 405 and 135 hectares, consisting of stretches of primary forest mixed with secondary forest, were considered for mammal inventory. The evidence of mammals was verified directly (views) and indirectly (traces, trichology and interviews with local dwellers). It was recorded 32 species (including one exotic and two small ones), belonging to eight orders and 18 families. Nine animals of these species are at risk of extinction in the Parana State and five configure with insufficient data in the List of Endangered Species of the state. The results of this study indicate the great importance of these forest fragments in the conservation of several medium and large mammals in the Araucaria Forest of Parana State. Nevertheless, due to the negative pressures that these areas have been suffering, immediate and concrete public actions are required to ensure the maintenance of these mammal populations.

Variabilidade da precipitação pluvial na UGRH do Médio Paranapanema, Estado de São Paulo

The purpose of this work was to analyze the variability of pluvial precipitation at the Mid-Paranapanema Hydric Resources Management Unit (UGRI II-17), both spatially and temporally. To that effect, 33 pluviometric series were used, obtained from the National Water Agency (ANA), for the period from 1940 to 2000. The averages, standard deviation, upper and lower quartiles, maximum rainfalls, within the analyzed period, as well as the anomalies in these series, were calculated. The anomalies of the 1982/1983 El Nino, as well as the classification of homogeneous areas inside the basin were also calculated. Variability was observed from one year to the other, with rainier years - for example, 1982 and 1983 - and drier years - such as 1985 and 2000.

Intestino médio de larvas de Anticarsia gemmatalis (Hübner) (Lepidoptera: Noctuidae): estudo das células epiteliais ao microscópio de luz e eletrônico

The morphology of the midgut epithelium cells of Anticarsia gemmatalis (Hübner) larvae is described by light and transmission electron microscopy. The midgut of A. gemmatalis is the largest portion of the digestive tract, with three distinct regions: proximal, media and distal. Its wall is formed by pseudostratified columnar epithelial tissue having four cell types: columnar, goblet, regenerative, and endocrine cells. The columnar cells are numerous and long, with the apical portion showing many lengthy microvilli and the basal portion invaginations forming a basal labyrinth. The goblet cells have a large goblet-shaped central cavity delimited by cytoplasmic projections filled with mitochondria. The regenerative cells present electron-dense cytoplasm and few organelles. The endocrine cells are characterized by electron-dense secretory granules, usually concentrated in the cytoplasm basal region.

Structural and geochronological studies of the Médio Coreaú domain, NE Brazil: Constraints on Brasiliano/Pan-African tectonic evolution in the NW part of the Borborema Province

Recent structural investigations and geochronological studies of rocks from the Médio Coreaú domain in the NW part of northeast Brazil's Borborema Province provide important constraints on the tectonic evolution of the region both preceeding and during the assembly of West Gondwana. Field observations of structural features and fabrics have revealed the presence of four distinct deformational phases in the MCD: D1, D2, D3 and D4. Only the early Paleoproterozoic gneisses record the D1 tectonic event and its preservation is cryptic owing to strong overprinting by the subsequent tectonic phases. The D2, D3 and D4 events affected younger supracrustal rocks and Neoproterzoic magmatic units, and U-Pb geochronological constraints show that all of these tectonic phases represent deformational events that occurred during Brasiliano collision between the West African craton and the NW part of the Borborema Province. The D2 phase, lasting between ca. 622 and 591 Ma, represents a frontal collision stage, which generated NW verging thrust-nappe systems, low-angle foliation, high-grade metamorphism and crustal anatexis. Transition to a strike-slip regime (D3) occurred at around 591 Ma when the region entered a phase of escape tectonics. During this time, the motion of crustal blocks towards NE and E was accommodated along numerous anastomosing shear zones. Syntectonic emplacement of granitoid plutons took place in transtensional domains of the shear zone system. The intrusion of late tectonic granitoids and rapid uplift and cooling of the orogen around 560 Ma as a result of D4 transpressional movements marked the end of the D3 transcurrent regime. These findings show that only the early Paleoproterozoic gneisses in the Médio Coreaú domain are polycyclic in nature. Rather than representing distinct orogenic events, the D2, D3 and D4 tectonic phases are a manifestation of progressive deformational events that developed in response to changes in the regional stress field during convergence and collision between the Borborema Province and its surrounding cratons.

O espectro médio de longo termo na pesquisa e na clínica fonoaudiológica.

BACKGROUND: One of the great difficulties in evaluating a voice is the judgment of quality through the perceptual auditive analysis--although frequently used--, as it is influenced by socioeconomic and cultural aspects as well as individual preferences. Many are the adjectives and methods used in this assessment, especially because of the subjectivity involved in the process, leading to incompatibilities between listeners and difficulties in reaching a consensus on the use of this or that terminology. In such a context, the voice laboratory and more specifically the acoustic computerized analysis, has guided and complemented speech-language treatments. Among the several possibilities of spectrographic analysis, the (Long-Term Average Spectrum--LTAS) quantifies the quality of voices, pointing differences between gender, age, professional--spoken and sang--and dysphonic voices. The LTAS has been used a lot in researches that investigate voice. As it evidences the contribution of the glottic source and of resonance to the quality of voice, it provides objective parameters for the evaluation of this aspect which usually depends on our auditive perception. AIM: to demonstrate how LTAS can be applied in voice research and in the speech-language therapy practice, describing both the technical aspects required for the production and interpretation of results, and its limitations. CONCLUSION: The area of voice research has developed a lot in these last two decades especially because of the advent of the voice and speech laboratory. For this reason, the knowledge about the applicability of more tools for voice analysis, as the LTAS, as well as the existing need for more studies in this area, will most certainly contribute for the creation of new research areas not only in the field of professional voice but also in the field of therapy.

Foraging activity of Protopolybia exigua (Hymenoptera, Vespidae) in different phases of the colony cycle, at an area in the region of the Médio São Francisco River, Bahia, Brazil

In this work, the foraging activity of Protopolybia exigua (de Saussure) was studied, aiming to verify the amplitude of the foraging time, the relation between the physical factors of weather (temperature, relative air humidity, luminosity and wind speed) and the daily activity of searching for resources, as well as to analyze the influence of the colony development phases and the number of individuals (adults and immatures) engaged in such activity. The study was carried out in two areas of the city of Bom Jesus da Lapa, Bahia, Brazil, during the period from January to June 2006, when the observation of 12 colonies of P. exigua was performed. The results revealed this species presented an amplitude of activity of almost 13 hours. There was an average of 44.4 nest exits and 37.6 returns a day by the nest workers and the Returns with Resources Index for this species was 93.5%. The foraging activity increased as of 10:01, and became more intense, with the peak from 1:01 p.m. to 4:00 p.m., when the highest temperatures (°C) and the lowest values of relative air humidity (%) were observed. The colonies that had a larger number of larvae presented a higher average number of trips to the field per hour (10.94) and the number of females in the colony tends to induce foraging activity. There were no differences between the numbers of nest exits by the workers regarding the three phases of colony development.

Utilização do alcohol use disorders identification test (Audit) para identificação do consumo de álcool entre estudantes do ensino médio

Alcohol is one of the drugs most widely used among teenagers. Just recently, studies have been developed regarding the screening of use of alcohol by this population. This work aimed to investigate the use of AUDIT as a method for screening and evaluation of alcohol consumption among High School students. The sample was composed by 1227 students from two public schools, who answered to the Alcohol Use Disorders Identification Test (AUDIT) and informed their socioeconomic level, religion, and occurrence of relationship problems caused by drunkenness of family members. Using an 8 cut-off point, AUDIT has identified 17.8% of students with risk drinking. These results have revealed that AUDIT is easy to be applied and well accepted by the students. It was also evident the importance of this instrument in the follow-up programs of prevention and intervention of alcoholic beverages use.

Dinâmica regional e política urbana: Uma análise das cidades de porte médio da região administrativa de Campinas/SP

The process of internalization of development occurred in the state of Sao Paulo resulted in accelerated growth of intermediate cities leading to a pattern of development with sprawl, segregation and suburbanization. In this process stands the Administrative Region of Campinas, the hinterland region of higher growth and accumulating a larger number of medium-sized cities. Such questions imply the need for appropriate urban policies to confront these challenges, under risk to jeopardize the quality of life and environment of these cities. The implementation of the Estatuto da Cidade brings new perspectives for urban management in medium-sized cities. This study aims to evaluate the deployment of instruments of urban management in medium-sized cities in São Paulo, with emphasis on Administrative Region of Campinas, based on the Profile of Brazilian Municipalities 2008 conducted by IBGE. The results point to a worrying situation, as it did not see a correlation between the deployment of these instruments and the size, growth and income in the mid-sized cities.
