Authors: Azim Araghi M.E. , Shaban N. , Bahar M.
Published: April 2016

In this research work, nanocrystalline BST (Ba0.6Sr0.4TiO3) powders were synthesized through a modified sol-gel process, using barium acetate, strontium acetate and titanium isopropoxide as the precursors. In this process, stoichiometric proportions of barium acetate and strontium acetate were dissolved in acetic acid and titanium (IV) isopropoxide was added to form BST gel. The as-formed gel was dried at 200 °C and then calcined in the temperature range of 600 to 850 °C for crystallization. The samples were characterized by infrared spectroscopy method (FT-IR), X-ray diffraction technique (XRD) and field emission scanning electron microscope (FESEM) and energy dispersive X-ray spectroscopy. EDS analysis of these samples confirmed the formation of the final phase with the special stoichiometry. The formation of a cubic perovskite crystalline phase with nanoscale dimension was detected using the mentioned techniques. The results showed that the obtained crystallite sizes were 33 and 37 nm for BST powder calcined at 750 and 850 °C, respectively.
MERCOSUR and the Brazilian Leadership Challenge in the Era of Chinese Growth: A Uruguayan Foreign Policy Perspective
Authors: Urdinez Francisco , Burian Camilo López , de Oliveira Amâncio Jorge
Published: April 2016

In recent years, China has expanded its presence in Latin America leading to increased trade flows, foreign direct investment, and bilateral cooperation agreements. At the same time, Brazil has attempted to emerge as a global player from its belief in itself as a regional leader. While both countries are part of the emerging South, they are also competing for influence in the South American area. We hypothesize that for MERCOSUR members, deepening commercial ties with China would be a viable option to counterbalance Brazil’s regional leadership, using Uruguayan legislators preferences as a tool for our study. Using logistic models, we conclude that that the probability of supporting a hypothetical free trade agreement with China is larger when politicians viewed MERCOSUR as an obstacle to the interests of his or her country and when he or she had doubts about Brazilian de facto regional leadership. This empirical evidence allows us to reflect on the political consequences of free trade agreements, on Brazil’s leadership in South America, and Brazil-China relations from the perspective of South-South relations in general.
CITI-SENSE: methods and tools for empowering

public spaces
Authors: Aspuru Itziar , García Igone , Herranz Karmele , Santander Alvaro
Published: April 2016

The purpose of this research was to design and
deploy tools that apply the concept of citizen observatories
and empowering citizens in the assessment of acoustic
comfort in public places. The research applies an iterative
cycle of design and this article presents the results of a
demonstrative experiment carried out in situ using the first
products developed. This work was undertaken as part of
the CITI-SENSE project. A viable technical and procedural
solution was designed and tested in a field demonstration,
where 53 people were engaged to provide 137 observations
in the city of Vitoria-Gasteiz, using environmental
sensors connected to a smartphone. The results have been
analyzed and discussed in terms of the product’s attractiveness
for engaging citizens in the evaluation of acoustic
comfort in urban places, the accuracy of the noise levels
measured by the acoustic app service integrated into the
smartphone, and its ability to obtain simultaneous acoustic
and perception data. The results presented in this article
are considered a step forward in the research into developing
solutions for assessing acoustic comfort. Limitations
of the proposed solution are discussed, as are suggestions
for further research.
Influence of light intensity on the lifetime of carriers in silicon investigated by a photoacoustic method
Authors: Bychto L. , Maliński M.
Published: April 2016

The paper presents experimental results of the lifetime of light induced excess carriers in the n−type silicon. The lifetimes of carriers of silicon crystals were analysed as a function of the intensity of light illuminating the sample. As a measurement method of the lifetime of carriers, the photoacoustic method in a transmission configuration with different surfaces was used. The dependence character was next analysed in the frame of the Shockley Reed Hall statistics in approximation of the light low intensity.

Planting grass filter strips: Does it influence the structure and function of riparian habitats of agricultural headwater streams?
Authors: Smiley Jr. Peter C. , Rumora Kathryne R.
Published: April 2016

Grass filter strips are strips of cool or warm season grasses planted adjacent to agricultural streams to reduce nutrient, pesticide, and sediment input. This conservation practice is the most frequently planted riparian buffer type in the United States. Previous studies have not evaluated how grass filter strips alter the structure and function of riparian habitats of agricultural streams. Our objective was to examine the research hypothesis that planting grass filter strips will influence the structure and function of riparian habitats of channelized agricultural headwater streams. We sampled riparian vegetation, quantified coarse particulate organic matter input and nutrient input, and measured water temperature within two unplanted riparian habitat sites, two riparian habitat with grass filter strips sites, and two forested riparian habitat sites of agricultural headwater streams in central Ohio. Forested riparian habitats exhibited greater percent maximum frequency of woody vegetation and reduced water temperatures than unplanted riparian habitats and grass filter strips. Forested riparian habitats also exhibited greater canopy cover, woody vegetation taxa richness, and coarse particulate organic matter input than grass filter strips and greater riparian widths and woody vegetation abundance than unplanted riparian habitats. Grass filter strips did not differ in structure and function from unplanted riparian habitats. We conclude that planting grass filter strips does not influence the structure and function of riparian habitats of channelized agricultural headwater streams.
Numerical modelling of sea currents and tidalwaves
Authors: Zalesny Vladimir B. , Gusev Anatoly V. , Lukyanova Anna N. , Fomin Vladimir V.
Published: April 2016

We consider a mathematical model of sea currents and tidal waves based on the marine dynamics primitive equations. The equations are written in the orthogonal coordinate system on sphere with arbitrary position of the poles. It makes it possible to increase horizontal resolution due to placement of a pole into vicinity of the considered sub-area. Two problems are solved: (1) joint computation of wind-generated, baroclinic and tidal currents in the Black and Azov Seas; (2) simulating mesoscale variability of coastal currents in the Black Sea. The second problem is solved with increased horizontal resolution in the coastal zone of Gelendzhik.
Quantity versus Price Bank Competition and Macroeconomic Performance Given Bank Concentration
Authors: Varelas Erotokritos
Published: April 2016

This paper elaborates upon the following three theses: First, given bank sector concentration, the other aspect of this sector that matters for the overall economy is that of pricevs. quantity competition by itself. Second, the macroeconomic performance of price competition is superior, enhancing the tax base and bank profit, capitalizing additionally the banks upon public debt induced instability, which the policymaker can minimize through Taylor rule. And, third, the ultimate link between banking competition and macroeconomic performance is the bank regulation shaping bank operation in accordance with the financial needs of fiscal policy.
Superneutrality of Money under Open Market Operations
Authors: Homburg Stefan
Published: April 2016

Monetary policy is superneutral in an overlapping generations model. Previous authors have argued that superneutrality does not hold in such a setting. However, the standard results rely on the counter-factual premise of helicopter money and are overturned if money creation through open market operations is taken into account. This result suggests that a more realistic representation of monetary policy may generally be helpful.
Educating for Ecological Literacy
Authors: Goodwin Timothy
Published: April 2016

Based on the life experiences of six prominent environmental voices – Fritjof Capra, David Quammen, Brian McLaren, Douglas Wood, Sylvia Earle, and Louise Chawla – I recommend changes in curriculum content for general science courses, specifically biology courses, to increase the ecological identity of our next generation. Experiences that allowed these individuals to develop an emotional connection to the natural world were an important component of their ecological identity. Coupling outdoor experiences with the development of systemic and ecological thinking skills was also crucial. Changing the science curriculum to reflect more holistic and systemic thinking by integrating with humanities and reflective practices is a necessary step to create a population with a highly developed ecological identity.
Biodiversity Education & the Anthropocene: An Indicator of Extinction or Recovery
Authors: Cohen Joel I.
Published: April 2016

The importance of extant biodiversity, concerns regarding the rising Anthropocene extinction rates, and commitments made by signatories to biodiversity conventions each increase demands for timely data. However, as species and conservation indicators become more complex, the less accessible they are to educators. New pedagogies are needed so that students can generate their own data for studies of biodiversity and extinction. I present a simple indicator of species diversity that examines declines in species’ populations and whether or not these species subsequently recovered or faced extinction. Using such data, 14 threatened species are used as examples of the time taken for each species to reach a point of either recovery or extinction. The learning and pedagogical context for this information is reviewed, student use of the data demonstrated, and the lesson evaluated according to its learning objectives.

Para ello, se estudiará la vida y obra de los hermanos suizo-italianos Francesco y Lorenzo Durini Vasalli. La contribución arquitectónico-cultural de los Durini es comentada a partir del análisis de las Casas de Corrección (1897-1902). Para la investigación se consultaron fuentes primarias y secundarias, las cuales fueron comparadas y analizadas bajo el método hipotético-deductivo. Mediante el análisis de las Casas de Corrección podemos corroborar la importancia que tuvieron los hermanos Durini para la transformación del paisajeurbano josefino. 
De la crónica al ser profundo: pintura y cultura popular mexicana en Luis Cardoza y Aragón
Authors: Delgado Aburto Leonel
Published: April 2016

Este artículo analiza algunas líneas esenciales de la intervención de Luis Cardoza y Aragón en el debate sobre la cultura mexicana posrevolucionaria, particularmente en la pintura y la cultura popular. El ensayo argumenta que Cardoza parte del acercamiento característico de la crónica literaria pero que su texto se mezcla con el ensayo y la crítica de arte. Los textos de Cardoza están orientados por la visión radical de las vanguardias, pero no se fijan en la vida urbana, sino en el análisis del ser mexicano. En su discurso se muestra la preocupación por la construcción nacional así como el uso de una perspectiva enriquecida por el cosmopolitismo estético de las vanguardias.
Central Bank Credibility: Determinants and Measurement. A Cross-Country Study
Authors: Mackiewicz-Łyziak Joanna
Published: April 2016

This paper proposes a new measure of central bank credibility — the credibility index calculated on the basis of the key determinants of central bank credibility. The index is compiled for 9 countries: the Czech Republic, Hungary, Slovakia, Poland, Chile, Brazil, Turkey, United Kingdom and Sweden , for the years 1999–2007. The results are cross-checked with other credibility measures based on inflation expectations of two groups of economic agents. The analysis demonstrates that the credibility index may be considered a relevant and consistent credibility measure.
Measuring Firms’ Input Congestion with Consideration of Environmental Factors: The Case of European Railway Transport
Authors: Lin Erwin
Published: April 2016

In practice, input congestion effects appear in railway transport due to the difficulties of disposing of unnecessary input factors. This study measures the output-oriented technical efficiency and input congestion with consideration of categorical variables for railway transport by using the DEA extension approach. The empirical results from 24 European railway companies show that in 12 railways, the presence of weak congestion can be proved. Based on the results of identifying the source(s) of input congestion and further determining its amount, one can obtain more insights into railways’ operation and thus propose more effective strategies for improvement.
A metformin-monoterápia és a szitagliptin/metformin fix kombináció egyéves perzisztenciája
Authors: Simonyi Gábor , Ferenci Tamás
Published: April 2016

Introduction: In treatment of type 2 diabetes mellitus it is important to reach glycaemic targets. The elements of this are the adequate diet and the patient’s adherence to medication. Aim: The aim of the authors was to investigate the one year persistence of the metformin monotherapy and sitagliptin/metformin fixed dose combination in type 2 diabetic patients. Method: National Health Insurance Found prescriptions database of Hungary on pharmacy-claims between October 1, 2012 and September 30, 2013 was analyzed. The authors identified patients who filled prescriptions for metformin monotherapy and fixed dose combinations of sitagliptin/metformin prescribed for the first time. Patients have not received similar drugs one year previous to study. To model the persistence, the apparatus of survival analysis was used, where “survival” was the time to abandon the medication. As it was available to month precision, discrete time survival analysis was applied: a generalized linear model was estimated with complementary log-log link function with the kind of drug being the only explanatory variable. Results: During the trial period, metformin monotherapy or sitagliptin/metformin fixed dose combination was started in 63,386 and 10,039 patients, respectively. One year persistence rate in patients with metformin monotherapy was 30%, and 58% in patients with sitagliptin/metformin fixed dose combination. Considering only the 360-day study period, the mean duration of persistence was 173.4 days in patients on metformin monotherapy and 261.9 days on sitagliptin/metformin fixed dose combination. The hazard of discontinuation was more than twofold higher during treatment with metformin monotherapy compared with the use of the sitagliptin/metformin fixed dose combination (hazard ratio = 2.267, p<0.001). Conclusions: There is a significant difference between the one year persistence of metformin monotherapy and sitagliptin/metformin fixed dose combination in type 2 diabetic patients. The result demonstrated sitagliptin/metformin fixed dose combination has a favourable patients’ adherence as compared to metformin monotherapy. Orv. Hetil., 2016, 157(16), 618–622.

Published: April 2016

Abstract Introduction: Musculoskeletal pain worth being investigated for being a multidimensional prevalent phenomenon, difficult to be understood which may have as main factors: tissue injury as well as emotional, social and environmental aspects. It is essential to know the specificity of the pain to define strategies for disease prevention and health promotion of the population. Objective: To estimate the prevalence of musculoskeletal pain, describing its features and functional implications in population from Belterra/Pará. Method: In a descriptive study, there were evaluated subjects who participated in activities of the project Bandeira Científica. Prevalence of pain was estimated with a confidence interval of 95%. Descriptive measures were used to characterize pain and consequences for functionality. Results: 453 subjects were interviewed, the mean age was 44.3 years old (SD = 18.0) and 69.6% were women. Prevalence of chronic pain was 62.5% and of back pain was 55.0%. Almost daily pain was felt by 67.9% and by 69.6% the intensity was strong or unbearable during crisis. Individuals with unbearable intensity and daily frequency of symptoms reported difficulty to perform heavy activities (91.5%) and to remain in the same position (82.9%). Conclusion: The prevalence of pain was high, of chronic feature, with high intensity and high frequency, long duration, most frequently in the vertebral column. The pain had interference in the performance of heavy activities and maintaining the same posture in people with greater intensity and frequency of pain.

Published: April 2016

Abstract Introduction: Environmental factors have also been recognized to be a component of a multidimensional gait assessment of people living with disabilities, like persons following an amputation. Objective: To investigated whether the environmental factors outlined by the International Classification of Functioning, Disability, and Health (ICF) are considered when evaluating gait following lower limb amputations. Materials and methods: A literature search of the PubMed, EMBASE, CINAHL, and SPORTDiscus databases was performed. The keywords "amputation" and "gait" were combined with the keywords "barriers", "facilitators", and "environmental factors". Searches were performed without language restrictions. All articles containing data about environmental influences on gait functionality after lower limb amputations published during or after 2002, were included. Manuscripts that did not study adults and literature reviews were excluded. Two researchers identified potentially eligible articles and the methods used to assess gait. To make comparisons between scales, the 2 researchers selected the categories from the ICF chapter on environmental factors. Results: Fourteen studies were obtained from the search. Seven studies were duplicates and 4 were excluded. The remaining 3 articles were evaluated. We identified a total of 74 possibilities for categorization according to the ICF environmental factors, but only 7 ICF categories (9.45%) were considered in the studies analyzed. Conclusions: The influence of environmental factors is frequently not considered in the evaluation of gait following a lower limb amputation. Thorough evaluation of gait after lower limb amputation should reflect the complex nature of gait changes, including environmental factors.
Whole-body vibration and musculoskeletal diseases in professional truck drivers
Authors: Moraes Geraldo Fabiano de Souza , Sampaio Rosana Ferreira , Silva Luiz Felipe , Souza Mariana Angélica Peixoto
Published: April 2016

Abstract Background: Most occupational diseases do not fit the paradigm of medical interpretation of the health-disease process based on linear causality, in which it would be possible to find a single cause for each type of disease. Objectives: to conduct a systematic review in order to investigate the association between whole-body vibration (WBV) and musculoskeletal disorders (MSD) in professional truck drivers (PTD). Methods: The scientific databases of PubMed, Cochrane, Lilacs and Scielo were used to collect articles published from 2000 until the present time. Two independent reviewers adopted inclusion and quality criteria to evaluate the selected articles. Results: From adopted inclusion and quality criteria, nine articles were chosen to identify the association between MSD and WBV in PTD. The results showed that MSD seems to be closely associated to exposure to WBV in these workers, mainly due to high prevalence and symptoms of low back pain. Two cohort studies showed exposure to WBV as risk for MSD. Only one, with case-control design, did not show WBV as a significant factor. Conclusions: In this study the importance of exposure analysis of WBV in the occurrence of MSD in PTD was elucidated. This study showed the importance of WBV exposure analysis on the occurrence of MSD in PTD. There is adequate information to provide rationale for the reduction of WBV exposure to the lowest possible level, to ensure the health of these workers. Studies with a greater power of investigation, of a prospective, design, should be encouraged, supplanting those only of association.

Published: April 2016

Abstract Introduction: Weakness of the lower limb muscles, which are the main impairments after stroke, is associated with reduced mobility and decreased performance in functional tasks. Therefore, the assessment of strength of these muscles is necessary, which is commonly assessed with portable dynamometry. Aims: To perform a literature review regarding the methods used to assess lower limb strength with portable dynamometry in subjects with stroke and to describe its investigated measurement properties with this population. Materials and Methods: An extensive search was performed on the MEDLINE, SCIELO, LILACS, and PEDro databases, by combining specific key words, followed by active manual search by two independent researchers. Results and Discussion: Thirty studies were included, and the muscular groups of the knee (90%) were the most assessed, followed by the ankle (66.7%) and hip (63.3%) joints. In 5% of the studies, there were not reported any descriptions related to the positioning of the subjects and the equipment, neither regarding the stabilization procedures. Only 50% provided information regarding the number of trials and only 46.7% regarding the contraction times, being three trials and 5s the most commonly applied. Only 10% provided feedback and 23.3% demonstrations, prior to data collection. Only seven studies (23.3%) investigated the measurement properties of portable dynamometry and reported moderate to high reliability levels. Final Considerations: The protocols used for the assessment of the strength of the lower limb muscles with portable dynamometry in subjects with stroke were not standardized. Moreover, only one measurement property was investigated: the reliability, which was considered adequate.

O mistério em A estranha morte do professor Antena
Authors: Santana Rafael
Published: April 2016

Resumo O início do século XX manifesta-se como um tempo de contestação das formas tradicionais de conhecimento, tais como a filosofia, a ciência e a própria escritura. Investindo nas instâncias do sonho e do mistério, a literatura de princípios de novecentos rejeita a lógica científico-positivista, clamando por novos valores. Este trabalho pretende ler o conto A estranha morte do professor Antena, de Mário de Sá-Carneiro, como uma narrativa que compreende a memória enquanto discurso onírico que se opõe à racionalidade científica.

Control y fugas en la era digital, en El delirio de Turing, de Edmundo Paz Soldán
Authors: von Werder Sophie Dorothee
Published: April 2016

Resumen Lectura de la novela El delirio de Turing (2003) como evaluación estética del carácter totalitario de las democracias neoliberales, y de su relación con las tecnologías. Se estudia de qué manera Paz Soldán actualiza la reflexión sobre la lucha entre los poderosos y los oprimidos en un nuevo campo de batalla que es el mundo virtual. El delirio de Turing se compara con la novela anterior, Sueños digitales (2000). Las perspectivas, sin ser excluyentes, representan diferentes enfoques, y no se llega a la misma conclusión. Mientras en la primera, el control del Estado es total, en la más reciente se observan fugas. En El delirio de Turing, el gesto utópico está presente, no obstante es limitado. La sociedad retratada no solo es postdemocrática, también se torna paranoica.
Catálogo dos mortos:a cultura latino-americana contemporânea e os inventários do horror
Authors: Ribeiro Gustavo Silveira
Published: April 2016

Resumo O texto procura compreender, a partir da obra de quatro escritores e artistas – Juan Carlos Romero, Roberto Bolaño, Nuno Ramos e André Vallias – os significados que inventários, catálogos e listas assumem na cultura latino-americana das últimas décadas, em especial a ligação que mantêm com a reflexão sobre a violência que atravessa, enforma e constitui parte significativa dessa mesma cultura. Trata-se de um processo de ressignificação formal, uma vez que listas e enumerações eram já marcantes na cultura da América Latina colonial, associada aos inventários narrativos do exótico e do maravilhoso produzidos por viajantes e conquistadores. No âmbito contemporâneo, entretanto, o que se vai observar é uma (re)invenção política da linguagem e da técnica, a emergência de outras listas, agora verdadeiros inventários do horror: diante do insuportável da violência, a arte e a literatura elaboram os seus catálogos da dor e da revolta, parte da infinita tarefa da memória e do luto.

Authors: Bonifácio Kallyne Machado , Freire Eliza Maria Xavier , Schiavetti Alexandre
Published: April 2016

The Cultural Keystone Species (CKS) method of identification has been used to define culturally important species. The objective of this study was to identify and characterize CKS vertebrates in the communities surrounding the Environmental Protection Area of Chapada do Araripe and define conservation priorities using semi-structured interviews and free listings. Interviews were conducted with 246 people; 53 species were identified and then included in categories of use: food, medicinal, handicraft and symbolic. Food preference was identified for Mazama gouazoubira, Penelope superciliaris, Dasyprocta prymnolopha and Dasypus novencimctus. As medicinal resources, Salvator merianae and M. gouazoubira represented 51.85% of treatment recommendations. For use in handicrafts, M. gouazoubira, which is also the only species recorded for symbolic use, stands out. Use values (UV) varied from 0.03 to 1.34, and M. gouazoubira had the highest UV (1.34) and a 0.74 projection. Regarding cultural importance, M. gouazoubira was the species with the highest UV and projection, and was indicated as a CKS to be prioritized in research and conservation studies.

Published: April 2016

Fresh water biodiversity is an increasing concern due to growing human impact. Herein, we report a long-term survey (ca. 90 years) of sedimentary diatoms and the modern flora from surface sediments and their biodiversity changes along a eutrophication gradient. Study was carried out in one of the most important water supply reservoirs (Guarapiranga Reservoir) of São Paulo Metropolitan Region, Brazil. Results are based on 75 core subsamples (subfossil assemblages from core) previously dated by 210Pb and 14 samples from surface sediments (modern assemblages). Overall, 84 taxa were reported, belonging to 30 genera, 71 species and eight non-typical varieties, besides five probable new taxa. Results expanded two new additions for the Brazilian diatom flora (Chamaepinnularia submuscicula and Stauroneis acidoclinata) and 30 infrageneric taxa for the state of São Paulo. 47.6% of total taxa inventoried were accounted exclusively for the subfossil assemblages indicating a significant biodiversity change over time. Access to past oligotrophic conditions and to contemporary mesotrophic regions of the Guarapiranga Reservoir accounted for these new additions representing 25% of the total diatom flora. Decline in the total species number along the trophic state gradient occurred for subfossil and modern assemblages. This pattern was even clearer when considering the changes in species richness over time.Eunotia with 21 taxa was the far most represented genera particularly in the oligotrophic phase. During the transitional period (1947-1974), richness gradually declined. With the onset (in the 1970s) and the major eutrophication period (since ca. 1990) occurred a drastic reduction in richness and the replacement of oligotrophic to eutrophic species. Human management also caused abrupt changes in richness. Marked decline occurred (1933) assotiated with hydrological impacts (water discharge increase) with the initial use of the reservoir as a public water supply. Unlike, sudden increase occurred probably associated with the application of algaecide to control cyanobacterial blooms. Present findings highlight the need for surveying the diatom assemblages in protected environments or in less degraded conditions for biodiversity assessment. Furthermore, reinforce the use of paleolimnological approach as in many cases the only tool to assess biodiversity changes encompassing time scales relevant to human-induced degradation and pre-anthropogenic impacts.

Published: April 2016

Abstract Background Depressive symptoms are highly prevalent among the elderly population (10%). These symptoms frequently appear when there is a loss of quality of life associated with social exclusion and the appearance of severe diseases. Feelings of sadness, discouragement, despondency and deception, and events such as the loss of close friends and family can also be related to these symptoms. The consequences of depressive symptoms include negative oral health outcomes, such as a decrease in the frequency of toothbrushing, greater prevalence of caries and higher probability of the appearance of periodontitis. Aim This study aimed to evaluate the association between the presence of depressive symptoms and problem-oriented oral healthcare behavior, as well as the absence of healthcare-seeking behavior. Material and method 872 elderly people living in two health districts in Porto Alegre were evaluated. They provided information on socioeconomic variables at an interview, and responded to the Geriatric Depression Scale-15 and to a questionnaire assessing dental care-seeking behavior. In addition, an oral examination was performed. When analyzed using Poisson regression with robust variance, the variables of male sex, less schooling, lower income, reduced number of teeth, presence of root remnants and presence of depressive symptoms were found to be independently associated with the outcome. Result There was a significant difference regarding dental care-seeking behavior in relation to elderly people presenting depressive symptoms and those in low socioeconomic strata having poor oral status. Conclusion It was concluded that these factors need to be taken into consideration when evaluating dental care-seeking behavior.
Reappraisal of Rhamdia branneri Haseman, 1911 and R. voulezi Haseman, 1911 (Siluriformes: Heptapteridae) from the rio Iguaçu with notes on their morphometry and karyotype

ABSTRACT The species Rhamdia branneri Haseman, 1911 and the subspecies Rhamdia branneri voulezi Haseman, 1911 from rio Iguaçu are currently recognized as synonyms of Rhamdia quelen (Quoy & Gaimard, 1824). However, recent karyotype and ecomorphology studies distinguish R. branneri and R. voulezi as different species. Examination of Rhamdia populations from rio Iguaçu, including type specimens, together with other congeners from rio Tibagi, allowed to properly reexamine the situation of these Haseman's taxa and references given to Rhamdia in the Iguaçu. The species R. branneri and R. voulezi have strong serrae with large basis on both margins of the pectoral-fin spine, uncommon in the remaining species of Rhamdia and different from the fine serrate margins of the pectoral spine of R. quelen ; a regular dorsal profile, slightly curved between supraoccipital and dorsal fin; with dorsal dark-brown or light-gray coloration along body, abdomen pale, without profuse small black spots, common in populations of the upper Paraná species and the type-material of R. quelen . Also the following morphometric characters discriminate these species: Rhamdia voulezi , adipose fin elongate; smaller distance between dorsal and adipose fin; smaller length between adipose fin to base of caudal fin and smaller distance from posterior margin of eye to opercular border. Rhamdia branneri , larger distance from dorsal and adipose fins; deeper caudal peduncle; higher trunk depth in the vertical distance through adipose, between pelvic and anal fins; larger scapular bridge; shorter maxillary barbel; shorter external mental barbel; shorter interorbital distance; shorter length of dorsal fin basis and shorter adipose-fin base length. A PCA between the populations of Rhamdia from Iguaçu and a population from rio Tibagi, upper Paraná basin, discriminates the population from Tibagi on basis of dorsal to adipose fin distance, dorsal-fin spine length, maxillary barbel length, eye diameter, and pectoral-fin spine length. This morphometric study allied to the karyotype known differences suggest R. branneri and R. voulezi as valid species. The complex state of R. quelen with the neotype recently designated from rio Samiria recommend new studies on basis of molecular genetics and provision of the names R. branneri and R. voulezi in the Iguaçu basin.
A new species of Moenkhausia Eigenmann (Characiformes: Characidae) from the upper rio Machado at Chapada dos Parecis, rio Madeira basin, Brazil
Authors: Ohara William M. , Marinho Manoela M. F.
Published: April 2016

ABSTRACT A new species of Moenkhausia is described from the upper rio Machado at Chapada dos Parecis, rio Madeira basin, Rondônia State, Brazil. Among congeners, the new species is similar to Moenkhausia chlorophthalma, M. cotinho , M. lineomaculata , M. plumbea, and M. petymbuaba by having dark blotches on the anterior portion of the body scales, which are absent in the remaining species of the genus. The new speciesdiffers from aforementioned species by possessing blue eyes in life, 15-18 branched anal-fin rays, and a well-defined, round caudal-peduncle spot that does not reach the upper and lower margins of the caudal peduncle and does not extend to the tip of the middle caudal-fin rays.
A new species of Gymnogeophagus Miranda Ribeiro from Uruguay (Teleostei: Cichliformes)
Authors: Loureiro Marcelo , Zarucki Matías , Malabarba Luiz R. , González-Bergonzoni Iván
Published: April 2016

ABSTRACT We describe a new species of a substrate-brooding Gymnogeophagus , based on coloration characters. The new species can be distinguished from the remaining substrate-brooding species in the genus by the unique pigmentation of the dorsal fin which consists of light blue, diagonal stripes over a red background in the spiny section and a combination of round, elliptic, and elongated bright blue spots over a red background in the soft section. It can be further distinguished from all other species of Gymnogeophagus by the following combination of characters: a discontinuous bright blue band above the upper lateral line in the humeral area, light blue roundish spots over a red to orange background on the anal fin, and conspicuous bright blue horizontal bands on body. The new species inhabits a wide range of freshwater habitats in the lower rio Uruguay basin, Rio de la Plata coastal drainages and Atlantic Ocean coastal drainages in Uruguay.
Revisionary study of the armored catfish Corydoras paleatus (Jenyns, 1842) (Siluriformes: Callichthyidae) over 180 years after its discovery by Darwin, with description of a new species

ABSTRACT The taxon known as Corydoras paleatus carries one of the most complex taxonomic histories among Corydoradinae catfishes. A comprehensive review of specimens attributed to that species from several localities was carried out, allowing the clear recognition of C. paleatus and also of a new species previously misidentified as C. paleatus , described herein. Corydoras paleatus can be distinguished from its congeners by presenting the following unique combination of features: perpendicularly directed serrations along entire posterior margin of the pectoral spine; three large black blotches along midline of flank; hyaline or black pectoral fin; and transversal black bars on caudal-fin lobes. Corydoras paleatus is known from the lower rio Paraná basin, coastal rivers from Southern Brazil and Uruguay and rio Uruguai basin. The new species can be distinguished from its congeners by having the following unique combination of features: three large black blotches along midline of flank; three nasal pores; mesethmoid short; infraorbital 2 not in contact with compound pterotic; striated black spots from the snout tip to nuchal plate region; markedly rounded snout; and anterior portion of dorsal fin spotted. The new species is known from the upper rio Uruguai basin, from the rivers Canoas, do Peixe and Pelotas.

RESUMO Objetivo Verificar a influência do cuidador informal na independência funcional de idosos no pós-operatório de fratura de fêmur proximal por quedas. Método Revisão integrativa, cujo corpus de análise reuniu 23 artigos, entre 2002 e 2012, das bases de dados Literatura Latino-Americana e do Caribe em Ciências da Saúde, Scientific Electronic Library Online, Cumulative Index to Nursing and Allied Health Literature, US National Library of Medicine e Scopus. Resultados Predominaram estudos com autoria de chineses e enfermeiros. A análise dos estudos evidenciou que as quedas seguidas por fraturas promovem a dependência de idosos e, consequentemente, a sobrecarga aos cuidadores, demonstrando o binômio idoso dependente-cuidador necessitar de apoio no processo de reabilitação. Conclusões Os cuidadores informais ainda precisam ser inseridos no planejamento e capacitados para o cuidado pelos profissionais da saúde, uma vez que influenciam positivamente a independência funcional no pós-operatório.

Authors: Freitas Rodrigo Jácob Moreira de , Moura Natana Abreu de , Monteiro Ana Ruth Macêdo
Published: April 2016

RESUMO Objetivo : Refletir sobre a violência contra crianças e adolescentes em sofrimento psíquico e o cuidado de enfermagem a partir da fenomenologia social. Métodos : Estudo teórico fundamentada nas concepções de Alfred Schütz. Resultados : O sujeito em sofrimento psíquico apresenta conflitos nas relações familiares, estando imerso em uma situação biográfica que retira sua autonomia, contribuindo para que aconteça ações violentas. Trata-se de um fenômeno social expresso por meio das relações de poder no mundo cotidiano e, através das relações dos nós, resultam em danos para as vítimas. Conclusões : A fenomenologia de Schütz possibilita novo olhar para o cuidado de enfermagem/profissionais de saúde que lidam com essa problemática, por permitir conhecer a situação biográfica e estoque de conhecimento de seus pacientes, suas motivações e significados atribuídos às experiências vividas. Possibilitando a superação do modelo biomédico e valorizando as relações intersubjetivas na perspectiva de uma cultura de paz.

Objective To describe the case of a patient with schizophrenia on clozapine treatment who had an episode of heat stroke. Case description During a heat wave in January and February 2014, a patient with schizophrenia who was on treatment with clozapine was initially referred for differential diagnose between systemic infection and neuroleptic malignant syndrome, but was finally diagnosed with heat stroke and treated with control of body temperature and hydration. Comments This report aims to alert clinicians take this condition into consideration among other differential diagnoses, especially nowadays with the rise in global temperatures, and to highlight the need for accurate diagnosis of clinical events during pharmacological intervention, in order to improve treatment decisions and outcomes.
