Abstract Marine Protected Areas (MPAs) in Brazil, like the “Refúgio de Vida Silvestre do Arquipélago de Alcatrazes”(REVIS de Alcatrazes), contain great species diversity. For conservation purposes, investing in local monitoring and surveillance is necessary. In this sense, Passive Acoustic Monitoring (PAM) has been used to collect acoustic data from marine environments. Therefore, this study assessed the frequency of vessels in the mentioned MPA in 2019 using PAM. Audio records collected by a hydrophone anchored at Saco do Funil (24°05’S; 45°41’O), located around 500 m from the main island of the archipelago, were used. Each audio file underwent a visual inspection of the spectrograms to detect the acoustic signals. The noise related to vessels transit was identified in 10% of the analyzed files, of which approximately 46% of the occurrences did not correspond to visits by the MPA management office. The area was most frequented from 6 am to 2 pm. The occurrence of non-official and unauthorized vessels was mostly concentrated from 3 am to 6 am and at 0 am. The study also underscored the biological significance of the MPA, revealing this area potential to be regularly visited by baleen whales in July and toothed whales throughout the analyzed months. So far, this is the only known surveillance investigation that used the PAM in MPAs along the Brazilian coast. Improvement and expansion of this technique use may lead using acoustics as an important auxiliary tool in monitoring MPAs on the Brazilian coast.

Abstract INTRODUCTION: Visceral leishmaniasis (VL) is an important zoonosis in Brazil. Previous identification of parasitized dogs can also help prevent the disease in humans, even in non-endemic areas of the country. The Brazilian Ministry of Health recommends diagnosis in dogs using a DPP® (rapid test) as a screening test and an immunoenzymatic assay (ELISA) as a confirmatory test (DPP®+ELISA), and culling infected dogs as a legal control measure. However, the accuracy of these serological tests has been questioned. METHODS: VL in dogs was investigated in a non-endemic area of the São Paulo state for three consecutive years, and the performances of different diagnostic tests were compared. RESULTS: A total of 331 dog samples were collected in 2015, 373 in 2016, and 347 in 2017. The seroprevalence by DPP®+ELISA was 3.3, 3.2, and 0.3%, respectively, and by indirect immunofluorescence assay (IFA), it was 3.0, 5.6, and 5.5%, respectively. ELISA confirmed 18.4% of DPP® positive samples. The concordance between the IFA and DPP® was 83.9%. The concordance between IFA and DPP®+ELISA was 92.9%. A molecular diagnostic test (PCR) was performed in 63.2% of the seropositive samples, all of which were negative. CONCLUSIONS: In non-endemic areas, diagnostic tests in dogs should be carefully evaluated to avoid false results.

RESUMO: A leptospirose é uma zoonose causada pelo agente etiológico Leptospira. Cães domésticos atuam como hospedeiro de diversos sorovares deste agente. Com intuito de analisar a dinâmica da leptospirose em uma população canina, com e sem imunização, um estudo longitudinal foi realizado avaliando a resposta sorológica destes animais e identificando seus sorovares. Foram coletadas amostras de 331, 373 e 347 cães em três anos consecutivos (2015 a 2017). As soroprevalências foram de 11%, 7% e 14%, respectivamente, e a incidência em 2016 foi de 5% e em 2017 de 14%. Os sorovares mais frequentes foram Cynopteri e Butembo em 2015, Cynopteri, Butembo e Hardjoprajitno em 2016, e Canicola e Butembo em 2017. Estes cães estão atuando como bio-indicadores da presença de Leptospira na região do estudo, incluindo sorovares zoonóticos, e contribuindo com a sua manutenção no ambiente. A soropositividade para sorovares protegidos pela vacina foi mais alta do que nos anos anteriores à imunização, enquanto para os sorovares não protegidos pela vacina diminuiu, demonstrando a importância da imunização para essa população de cães. Medidas de prevenção e controle para a leptospirose, como imunização e controle populacional canino, são recomendadas no local para inibir a transmissão do agente entre as populações de cães e humanos envolvidas.

ABSTRACT: Leptospirosis is a zoonotic disease caused by Leptospira and domestic dogs can act as host of some serovars. In order to analyze the transmission dynamics in a dog population, with and without immunization, a longitudinal study was carried out with a focus to evaluate antibody response and to identify serovars. Blood samples were collected in three consecutive years (2015 to 2017) from 331, 373 and 347 dogs respectively. The dog seroprevalence in each year was 11%, 7% and 14%, respectively, and the incidence in 2016 was 5% and in 2017, 14%. The most frequent serovars were Cynopteri and Butembo in 2015, Cynopteri, Butembo and Hardjoprajitno in 2016, and Canicola and Butembo in 2017. Dogs can play a role as sentinel animals and hosts of Leptospira serovars. The percentage of seropositive dogs due to vaccination was higher than the previous years without immunization and lower than in previous years for other serovars, which we interpret as evidence for the importance of immunization. These parameters associated with active canine population control are important for prevention and control of leptospirosis not only in dogs but alsoto inhibit the transmission between dogs and humans.

Resumo Os cães são hospedeiros dos protozoários Toxoplasma gondii, que causam uma importante doença para a saúde pública, e Neospora caninum. Estudos que avaliam a toxoplasmose e a neosporose por períodos prolongados em populações caninas são raros. Foi analisada a infecção por esses dois parasitas em uma população de cães domésticos e domiciliados por três anos consecutivos, no Estado de São Paulo, Brasil. Nos 1º, 2º e 3º anos de coletas, 181, 193 e 172 domicílios foram visitados, nos quais foram coletadas amostras de sangue de 331, 371 e 348 cães para sorologia, respectivamente. A soroprevalência de T. gondii em cada ano foi de 27,2%, 22,5% e 43,9%, respectivamente; e a de N. caninum foi de 7,8%, 4,8% e 6,8%, respectivamente. As taxas de incidência para T. gondii, nas 2ª e 3ª coletas, foram de 13,2% e 30,0%, respectivamente; e para N. caninum, 3,3% e 4,4%, respectivamente. As conversões sorológicas positivas e negativas para ambos os agentes ocorreram em alta frequência durante o período analisado. Este estudo revela o perfil sorológico da população canina e demonstra sua constante exposição aos patógenos investigados, o que requer medidas de prevenção e controle na região.

Abstract Dogs are hosts of the protozoans Toxoplasma gondii, which causes an important public health disease, and Neospora caninum. Studies that have evaluated toxoplasmosis and neosporosis for prolonged periods in dog populations are rare. We analyzed infection by both parasites in a domestic dog population over three consecutive years in São Paulo state, Brazil. In the 1st, 2nd and 3rd years of collection, 181, 193 and 172 domiciles were visited, and blood samples of 331, 371 and 348 dogs were collected for antibody serology, respectively. The seroprevalence of T. gondii in each year was 27.2%, 22.5% and 43.9%, respectively, and that of N. caninum was 7.8%, 4.8% and 6.8%, respectively. The incidence rates for T. gondii in the 2nd and 3rd collections were 13.2% and 30.0%, and those for N. caninum were 3.3% and 4.4%, respectively. Positive and negative serological conversions for both agents occurred at high frequencies during the study period. This study reveals the canine population’s serological profile and demonstrates the constant exposure of dogs to the investigated pathogens, indicating the need for prevention and control measures in the region.

RESUMO O presente estudo analisou a influência de dois protocolos de limpeza e desinfecção na frequência de Aspergillus spp. em instalações de frangos de corte. Realizou-se estudo observacional, aplicando-se dois protocolos de limpeza e desinfecção antes do alojamento de 960 pintainhos de um dia distribuídos aleatoriamente em 32 boxes com 30 aves. Foram realizados 2 experimentos independentes, que diferiam quanto ao material de cama, sendo nova no primeiro e reutilizada no segundo. Realizou-se dois tratamentos: Comum que incluiu varrição da matéria orgânica, umidificação do material residual com água sob baixa pressão, lavagem com detergente neutro e enxágue. O tratamento Europeu seguiu as recomendações do fabricante dos desinfetantes, incluindo remoção de matéria orgânica seca e úmida, umidificação, lavagem com água sob alta pressão, aplicação de detergente, enxágue e aplicação de dois desinfetantes compostos: glutaraldeído (250 g / L) + formaldeído (185 g / L); p-cloro-m-cresol (210 g / L). Foram coletadas amostras de superfícies e equipamentos antes e após a limpeza e desinfecção, aos 7, 14, 28 e 42 dias do período experimental para avaliação micológica, realizada em placas de Petri contendo AFPA (Aspergillus Flavus e Parasiticus Agar, Sigma Aldrich®). O tratamento Comum obteve maior presença de fungos nos pisos e paredes (83% vs. 0% p = 0,0030 e 50% vs. 0% p = 0,0450) no primeiro e segundo experimentos, respectivamente. Este estudo demonstra que a execução de um protocolo detalhado de limpeza e desinfecção, como o tratamento Europeu, reduz a presença de Aspergillus spp. em instalações de frangos de corte.

ABSTRACT The present study analyzes influence of two cleaning and disinfection protocols on frequency of Aspergillus spp. in broiler facilities. We conducted an observational study, applying two cleaning and disinfection protocols before housing 960 one-day-old broilers randomly allocated in 32 boxes with 30 birds. We considered two types of housing as independent experiments, which differed as to the bedding. First experiment consisted of new bedding materials, which we reused in second experiment. We applied two different treatments, Common treatment included sweeping organic matter, humidifying residual material with low pressure water, washing with water and neutral detergent, with posterior rinsing. European treatment was according to the standards of the manufacturer of disinfectants. Procedures included dry and humid organic matter removal, humidification, washing with high pressure water, application of detergent, rinsing, and application of two compound disinfectants: glutaraldehyde (250 g/L) + formaldehyde (185 g/L); p-chloro-m-cresol (210 g/L). To evaluate the presence of Aspergillus spp., we collected samples from surfaces and equipment before and after cleaning and disinfection, at 7, 14, 28, and 42 days of experimental period. Mycological assessment included streaking on Petri dishes containing AFPA (Aspergillus Flavus and Parasiticus Agar, Sigma Aldrich®). Common cleaning and disinfection treatment led to a higher presence of fungus in floors and walls (83% vs. 0% p = 0.0030 and 50% vs. 0% p = 0.0450) in first and second experiments, respectively. As this study demonstrates by using the European procedures, performing a detailed cleaning and disinfection protocol reduces the presence of Aspergillus spp. in broiler facilities.

The Geological and Mining Survey of Argentina, SEGEMAR, carries out the "Prospection of Sedimentary Zeolites in Argentina" project through the Geological Mineral Resources Department with the participation of several areas, including the Remote Sensing and GIS Division. The results obtained from ASTER data digital processing in Piedra Parada area, Río Chubut Medio, Cushamen and Languiñeo departments, at the NW of Chubut province are presented in this work, related to fallen tufits reworked and de-posited in a volcanic caldera (Tufolitas Laguna de Hunco, Paleocene-Eocene). As a classification method the Spectral Angle Mapper algorithm was applyed and spectral patterns of clinoptilolite, heulandite, mordenite and analcima were selected from USGS database. With a probability of oc-currence map, an exhaustive fieldwork and sample collection were carried out with the objective of determining the variability in zeolite distribution, its composition and validation of the image processing methodology. X-ray diffraction method (XRD) was applied and the diffractograms were interpreted to determine that the zeolitic rocks are composed mainly of clinoptilolite and / or heulandite. The characterization was complemented by reflectance measurements with spec-troradiometer which allowed adjusting the spectral classification and the assembly of the spectral base of zeolites of Chubut. Geological, vector and raster data, and XRD were loaded into data-bases and exported to a GIS for its integration. The results allow to validate the methodology of digital processing and to continue using it in the detection of zeolitic rocks in other Argentina regions in order to contribute and expand the prospection.

El Servicio Geológico Minero Argentino, SEGEMAR, lleva adelante el proyecto “Prospección de Zeolitas Sedimentarias en la República Argentina” mediante la Dirección de Recursos Geológico Mineros con la participación de diversas áreas, entre ellas la Unidad Sensores Remotos y SIG. En este trabajo se presentan los resultados del procesamiento digital de datos ASTER obtenidos en la zona de Piedra Parada, Río Chubut Medio, departamentos Cushamen y Languiñeo, al NO de la provincia del Chubut dónde aforan tobas de caída retrabajadas y depositadas en una caldera volcánica (Tufolitas Laguna de Hunco, Paleoceno-Eoceno). Como metodología de clasificación se utilizó el algoritmo Spectral Angle Mapper y patrones espectrales de los minerales clinoptilolita, heulandita, mordenita y analcima de la base de datos del USGS. A partir de un mapa de probabilidad de ocurrencia se realizó un exhaustivo trabajo de campo y recolección de muestras con el objetivo de determinar la variabilidad en la distribución de las zeolitas, su composición y realizar la validación de la metodología del procesamiento de imágenes. Se aplicó difracción de rayos X (DRX) y se interpretaron los difractogramas determinando que las rocas zeolitizadas están compuestas principalmente por clinoptilolita y/o heulandita. La caracterización se complementó con la medición de la refectancia con espectroradiómetro lo que permitió ajustar la clasificación espectral y el armado de la base espectral de zeolitas de Chubut. Los datos geológicos, vectoriales y raster, y DRX fueron volcados en bases de datos y exportados a un SIG para su integración. Los resultados permiten validar la metodología de procesamiento digital y continuar utilizándola en la detección de rocas zeolíticas en otras regiones de Argentina con el objeto de contribuir y ampliar la prospección.

RESUMO: Microrganismos causadores de mastites subclínicas em búfalas foram isolados desde 20 amostras de leite de búfalos de quatro granjas leiteiras localizadas na região central do Estado de São Paulo, Brasil, através dos testes contagem de células somáticas (CCS), contagem padrão em placas (CPP), provas bioquímicas, reações de PCR e perfil antimicrobiano. A CCS apresentou uma mediana de 721.000 cel/mL no leite, indicando presença de mastite subclínica. A média geral de CPP foi de 1,8x104 UFC/mL. Os microrganismos com maior frequência de isolamento segundo os testes bioquímicos foram: Staphylococcus epidermidis (17%), Staphylococcus aureus (15%), Bacillus spp. (14%), Acinetobacter spp. (12,5%); frequência intermediaria: Pseudomonas aeruginosa (9,5%); Shigella flexneri (7,0%), Streptococcus spp. (5,5%), Corynebacterium spp. (5,0%), Escherichia coli (4,5%), Serratia marcescens (4,0%), Stenotrophomonas maltophilia (4,0%), e baixa incidência: Klebsiella rhinoscleromatis (0,5%), Klebsiella ozaenae (0,5%), Tatumella ptyseos (0,5%), Enterobacter cloacae (0,5%). A análise molecular indicou que as amostras positivas pelo método de cultura dos gêneros Staphylococcus, Streptococcus e Escherichia coli foram positivas por PCR. Para S. aureus e S. epidermidis os maiores percentuais de sensibilidade observados foram gentamicina (100%) e vancomicina (100%); para o gênero Streptococcus à gentamicina e oxacilina e para E. coli à ampicilina. Este resultados podem ajudar no controle e tratamento da mastite subclínica em búfalos e contribuir para melhorar a eficiência e qualidade do leite produzido.

ABSTRACT: Microorganisms causing subclinical mastitis in water buffalo were isolated from 20 buffalo milk samples at four dairy farms located in central region of São Paulo State, Brazil, through testing of somatic cell count (SCC), standard plate count (SPC), biochemical, PCR assays and antimicrobial profile. The SCC showed average of 721,000 cells/mL in the milk, indicating the presence of subclinical mastitis. The overall average for SPC was 1.8 x 104 CFU/mL. The microorganism most frequently isolation according to biochemical tests were: Staphylococcus epidermidis (17%), Staphylococcus aureus (15%), Bacillus spp. (14%), Acinetobacter spp. (12.5%); with intermediate frequency: Pseudomonas aeruginosa (9.5%); Shigella flexneri (7.0%), Streptococcus spp. (5.5%), Corynebacterium spp. (5.0%), Escherichia coli (4.5%), Serratia marcescens (4.0%), Stenotrophomonas maltophilia (4.0%), and low incidence: Klebsiella rhinoscleromatis (0.5%), Klebsiella ozaenae (0.5%), Tatumella ptyseos (0.5%), Enterobacter cloacae (0.5%). The molecular analysis indicated that samples positive by culture method of the genera Staphylococcus, Streptococcus and E. coli were positive by PCR. Para S. aureus and S. epidermidis the highest percentages of observed sensitivity were gentamicin (100%) and vancomycin (100%); for the genus Streptococcus to gentamicin and oxacillin and E. coli to Ampicilin. These findings may help in the control and treatment of subclinical mastitis in buffaloes and contribute to improving the efficiency and quality of the milk produced.

Acalvaria é uma malformação congênita rara de patogênese desconhecida, na qual os ossos da abóbada craniana, a dura-máter e a musculatura associada estão ausentes, mas o sistema nervoso central costuma estar preservado. A teoria fisiopatogênica mais aceita sugere um defeito pós-neurulação, com disposição normal do ectoderma embrionário. O objetivo deste relato é descrever os achados de imagem neonatais da acalvaria primária.

Acalvaria is a rare congenital malformation of unknown pathogenesis characterized by the absence of the flat bones of the cranial vault, dura mater and associated muscles, while the central nervous system is usually preserved. The most accepted physiopathogenic theory suggests the presence of a postneurulation defect with normal placement the embryonic ectoderm. The present report describes neonatal imaging findings of primary acalvaria.

O estudo de instrumentos de avaliação psicológica no contexto de orientação profissional é de fundamental importância, pois favorece maior confiabilidade e enriquecimento da interpretação dos resultados. A presente pesquisa objetivou explorar as correlações entre as dimensões da Escala de Aconselhamento Profissional e as seções Competências, Carreiras e Habilidades do Self-Directed Search Career Explorer. A Escala de Aconselhamento Profissional é um instrumento que avalia as preferências por atividades profissionais e o Self-Directed Search Career Explorer traça o perfil tipológico dos interesses dos indivíduos. Participaram do estudo 132 estudantes (54,5% mulheres), com idade média de 15,9 anos, que cursavam o ensino médio de escolas particulares do interior paulista. Os resultados apresentaram correlações significativas (p<0,05) entre alguns tipos do Self-Directed Search Career Explorer e dimensões da Escala de Aconselhamento Profissional teoricamente relacionadas, tais como tipo Artístico com a dimensão Artes e Comunicação. Outras pesquisas devem ser desenvolvidas a fim de contribuir com estudos de outros instrumentos.

The study of instruments of psychological assessment in the context of vocational guidance is of fundamental importance, since it provides a greater reliability and enriches the interpretation of the results obtained. This research explored the correlation between the dimensions of the escala de aconselhamento profissional and the sections Skills, Careers and Abilities of the Self-Directed Search Career Explorer. The Vocational Advice Scale is an instrument that evaluates the preferences for vocational activities and the Self-Directed Search Career Explorer draws the typological profile of the individuals' interests. The participants included 132 students (54.5% were women), with average age of 15.9 years, attending private High Schools in São Paulo state. The results demonstrated significant correlations (p<0.05) between some types of Self-Directed Search Career Explorer and the escala de aconselhamento profissional dimensions. Further research should be developed in order to contribute to studies on new or existing instruments.

ASTER data allowed developing a simple methodology, using the Short Wave Infrared spectral bands (SWIR), in order to detect alteration minerals that affect igneous bodies and have spectral differences with the country rock. As an example chloritic alteration was detected in metabasalts interbedded in metasediments of Puntilla de Uspallata Formation, Precordillera Mendocina.

Los datos del sensor ASTER permitieron desarrollar una metodología sencilla, utilizando las bandas del infrarrojo de onda corta (subsistema SWIR), para prospectar cuerpos ígneos alterados que manifiestan diferencias espectrales con respecto a la roca de caja. A modo de ejemplo se detectó la alteración clorítica presente en metabasaltos intercalados en metasedimentitas de la Formación Puntilla de Uspallata en la Precordillera mendocina.

Este estudo relata a presença de Mycobacterium avium em quatro aves da ordem Psitaciformes, mantidos como animais de estimação. O exame anatomopatológico revelou a presença de bacilos álcool ácido resistentes na coloração de Ziehl-Neelsen, e o diagnostico definitivo foi feito pelo método PRA (PCR Restriction Analysis) a partir de tecidos emblocados em parafina. Este estudo visa alertar o possível potencial zoonótico deste agente em aves mantidas domiciliadas.

The present study is a report on the presence of Mycobacterium avium in four birds of the psittaciform order kept as pets. Anatomopathological diagnosis showed lesions suggestive of the agent and presence of alcohol-acid resistant bacilli (AARB) shown by the Ziehl-Neelsen staining. The identification of Mycobacterium avium was performed by means of PRA (PCR Restriction Analysis). DNA was directly extracted from tissue of the lesions and blocked in paraffin. The role of this agent in pet bird infection is discussed, as well as its zoonotic potential.

Um estudo anatomopatológico envolvendo 130 psitacídeos oriundos de centros de triagens, zoológicos e criadouros, visando a determinação da causa de morte destes animais, revelou a presença de neoplasias em sete animais, totalizando 5,4% dos casos. Os processos neoplasicos foram caracterizados como colangiocarcinoma, colangioma, linfoma, hemangiossarcoma e carcinoma renal primário, sendo o colangiocarcinoma o mais freqüentemente encontrado, presente em três animais. Este trabalho descreve estas neoplasias, levando em consideração os aspectos macro e microscópicos, meios de diagnósticos e espécies acometidas.

An anatomopathologic study of 130 captivy psittacines from zoos, breeders and rehabilitation centers showed the presence of neoplastic disease in seven birds, totalizing 5.4% of the cases. The neoplasms were identified like cholangiocarcinoma, cholangioma, lymphoma, haemangiosarcoma and renal cell carcinoma. The cholangiocarcinoma was the tumor most commonly observed. it was present in birds. This study describes the macro and microscopic findings of these tumors; also reports diagnostic methods employed to identify these neoplasms.

O uso de instrumentos psicometricamente ajustados ao contexto em que serão utilizados é fundamental para a confiabilidade de processos de avaliação psicológica. Em situações de orientação profissional, tal preceito tem igual importância, uma vez que a análise de diferentes construtos deve levar o sujeito a melhor se conhecer, proporcionando uma escolha adequada da profissão. O objetivo desse estudo foi correlacionar diferentes instrumentos de avaliação de interesses profissionais e inteligência, aplicados a 312 participantes de um programa de orientação profissional, com média de idade de 16,13 anos (DP = 2,07). Os resultados mostraram algumas correlações significativas entre BPR-5 e LIP, por um lado, e entre o INV e Angelini de outro. Novos estudos com amostras maiores e mais heterogêneas geograficamente são sugeridos, a fim de se obter mais evidências de validade, principalmente para os instrumentos ainda não aprovados pelo Conselho Federal de Psicologia.

The use of psychometrically adjusted instruments to the context in which they will be used is important to trust the psychological assessments process. In professional counseling situations, such use has the same importance, since different constructs analyses must provide a better self-knowledge, facilitating an adequate professional choice. The goal of this study was to correlate different intelligence and vocational interests instruments, answered by 312 students from a vocational counseling process, with age average 16.13 years old (SD = 2.07). Results showed significant correlations between BPR-5 and LIP, in one hand, and between INV and Angelini, in the other. New studies with larger and more geographically heterogeneous samples are suggested, aiming to get more validity evidences, mainly to the not approved instruments by the Federal institution that regulates psychological test use.

A process of stream piracy caused by the active retrograde erosion of Limay Chico stream -a tributary of Limay river- is described. It is located in the southern part of headwaters of the Alicurá drainage basin, tributary of Collon Cura river. It is supposed that the increment of the headward erosion is related to the postglacial climatic conditions and a coetaneous deepening of the Limay river channel, a process expressed by modern and lower erosion terraces. Moreover the retrograde erosion was enhanced by the special location of the Limay Chico valley along an important line of structural weakness, the Limay Chico fault. The fluvial capture and the consequent diversion of the Alicurá basin upper part showed previous favorable conditions: 1) the topographic lower disposition of Limay Chico stream and their base level; 2) its steeper slope and the location of Limay Chico valley along a zone of structural and litologicalk weakness; 3) transverse arrangement of the Alicurá river´s headwaters; 4) its gentle slope and location of their basin and base level at a topographic higher level. Several wind gaps were recognized and were interpreted two probable elbows of capture and barbed pattern. Also the increment of discharge of Limay Chico stream caused in their basin local phenomena of static rejuvenation. It is suppose a close genetic relation between the landslides observed along the steep fault scarp promoted by the Limay Chico Fault and the postglacial climatic change and the local erosional deepening of Limay Chico valley. The slumps characterized by the coalescence of their scars, generated the irregular and ruged landscape of the western side of Limay Chico valley. On the eastern valley slope the slumps reach minor expression. Longitudinal profils and slopes of the analized streams are included.

Se describe un proceso de captura fluvial, por erosión retrocedente, del arroyo Limay Chico -afluente del río Limay- sobre el sector austral de las cabeceras de la cuenca de drenaje del arroyo Alicurá, tributaria a su vez del río Collón Cura. Se interpreta que la causal del fenómeno estuvo relacionada con las nuevas condiciones climáticas postglaciarias (más húmedas) y la contemporánea profundización del troncal río Limay, morfológicamente expresada por modernas terrazas de erosión inferiores, las que fueran reconocidas en la zona de afluencia del arroyo Limay Chico, con anterioridad al llenado del embalse de Alicurá. Además, la captura fluvial y el consecuente desvío de los caudales de un tramo de las nacientes del arroyo Alicurá hacia la cuenca del Limay Chico, mostró condiciones o factores previos coadyuvantes: 1) la disposición topográfica inferior de la cuenca de éste último con respecto a la de Alicurá; 2) la mayor pendiente y la localización del valle del arroyo Limay Chico a lo largo de una zona de debilidad estructural y litológica representada por la falla Limay Chico, asistió la dinámica de la erosión fluvial retrógrada; 3) la disposición transversal de las cabeceras de la cuenca del arroyo Alicurá. Se han reconocido abras de viento e interpretado dos probables codos de captura. El consiguiente aumento de la descarga del arroyo Limay Chico, promovió en su cuenca un fenómeno local de rejuvenecimiento estático. También se acepta una estrecha relación entre el cambio climático postglaciario y la ocurrencia de los múltiples deslizamientos rotacionales observados a lo largo de la abrupta escarpa de falla generada por la falla Limay Chico, presumiéndose que la activa y coetánea erosión lateral del arroyo Limay Chico, contribuyó al proceso gravitacional. Estos deslizamientos, que se caracterizan por la coalescencia lateral de sus muescas de desprendimiento, han generado el distintivo e irregular paisaje del faldeo occidental del valle del arroyo Limay Chico. La incidencia de la remoción en masa también se observa en la ladera oriental del valle, aunque tiene menor expresión. Complementariamente se exponen los perfiles y pendientes de los cursos involucrados.

Considerando a importância que os instrumentos de avaliação psicológica possuem nos contextos profissionais do psicólogo, entre os quais as organizações, o presente estudo teve como objetivos: a) identificar os instrumentos mais utilizados em seleção profissional; e b) identificar as técnicas mais empregadas nos processos seletivos. Participaram como sujeitos desta pesquisa 15 estudantes último anistas do curso de Psicologia de uma instituição de ensino superior particular do interior paulista e 15 psicólogos recrutadores e selecionadores da região de Campinas. O material utilizado se constituiu de um questionário enviado aos profissionais por e-mail e distribuído aos estudantes na universidade. Os resultados mostraram que os instrumentos psicológicos mais utilizados nas seleções foram Wartegg, Atenção Concentrada, Teste de Inteligência Não Verbal G36, Bateria CEPA e Palográfico e as técnicas mais empregadas foram entrevistas individuais, dinâmicas de grupo e testes psicológicos. Sugere-se novos estudos na área como fomento para ações seguras relacionadas à avaliação psicológica.

Considering the importance of psychological assessment instruments in professional contexts of the psychologist (in organizations among others), the present study has the purpose of identifying not only the main useful strategies of recruiting people, but also the most innovative practices in the recruiting process. A group of 15 graduate students, in their last year of the Psychology Course at a private university in São Paulo's countryside, and 15 psychologists, who work as recruiters in the city of Campinas, participated in this research. A questionnaire was emailed to professionals and handled out to the university students. The results showed that the Wartegg, Concentrated Attention, Non-Verbal Intelligence Test G36, "Bateria CEPA" and "Palográfico" were the instruments most frequently used in the recruiting process, and the most common techniques were individuals interviews, group dynamic and psychological tests. New studies in this field are recommended in order to promote more reliable actions in psychological assessment.
