Abstract: Pervious concrete (PC) is considered a solution to reduce the effects of heat islands, runoff problems, and the concentrations of pollutants present in the water; however, its potential as a filter bed is used in the treatment of sanitary sewage has never been evaluated. This work aimed to assess the influence of photocatalytic TiO2 addition in PC on the concentration of total phosphorus, total ammonia, nitrate, total solids, and turbidity for application in the treatment of sanitary sewage. Sunlight was used as a radiation source. A flat photocatalytic reactor was built, in which 100 liters of raw sewage were pumped, with a flow of 100 L/min over the PC slabs, covering a total area of 1 m². The TiO2 concentrations added to the PC were 3, 6, and 10%. The results indicate efficiency in the adsorption of total phosphorus, total ammonia, nitrate, total solids, and turbidity. Thus, using PC associated with 10% TiO2 can add efficiency to the sanitary sewage treatment process by maintaining good mechanical and hydraulic behavior.
Resumen: El concreto permeable (CP) se considera una solución para reducir los efectos de las islas de calor, los problemas de escorrentía y las concentraciones de contaminantes presentes en el agua; sin embargo, nunca se ha evaluado su potencial como lecho filtrante en el tratamiento de aguas residuales sanitarias. Este trabajo tuvo como objetivo evaluar la influencia de la adición fotocatalítica de TiO2 en CP sobre la concentración de fósforo total, amoníaco total, nitrato, sólidos totales y turbidez para su aplicación en el tratamiento de aguas residuales sanitarias. La luz del sol se utilizó como fuente de radiación. Se construyó un reactor fotocatalítico plano, en el cual se bombearon 100 litros de aguas residuales sin tratar, con un caudal de 100 L/min sobre las placas de PC, cubriendo un área total de 1 m². Las concentraciones de TiO2 añadidas al PC fueron 3, 6 y 10%. Los resultados indican eficiencia en la adsorción de fósforo total, amoníaco total, nitrato, sólidos totales y turbidez. Por lo tanto, el uso de CP asociado con 10% de TiO2 puede agregar eficiencia al proceso de tratamiento de aguas residuales sanitarias al mantener un buen comportamiento mecánico e hidráulico.

We present our experience with a previously described flap, the shaped cone flap, to cover skin defects. This flap due its name to the shape, similar to an ice cream cone, that is formed by locally rotated and V-Y advance flaps joined together, being both fasciocutaneous flaps. We perform a retrospective analysis of 108 patients operated on between 2000 and 2013, aged 20 to 52 years, 99 males, treated with a cone shaped flap. The defects covered were located in the leg in 27%, in the ankle in 10%, in the sole of the foot in 9%, in the heel in 8% and in other locations in the rest of patients. Eighty flaps (74%) had a good evolution, 11 (10,2%) had a major dehiscence, 13 (12%) had a minor dehiscence and 4 flaps (3,7 %) had necrosis. We confirm the cone shaped flap as an easy and safe alternative for reconstruction that avoid complications in most of the cases and with a low surgical cost.
Presentamos nuestra experiencia con el uso de un colgajo previamente descrito, el colgajo denominado en cono por la forma final que obtiene, como la de un barquillo de helado con su bocado. Consta de 2 colgajos acoplados: uno de rotación local y otro un avance en V-Y, ambos fasciocutáneos. Realizamos un análisis retrospectivo de 108 pacientes intervenidos entre 2000 y 2013 por lesiones en diferentes partes del organismo, con edades comprendidas entre los 20 y los 52 años, de los cuales 99 fueron varones, y en los que empleamos este tipo de colgajo. Los defectos cubiertos afectaban a las piernas en el 27% de los casos, tobillos en el 10%, planta del pie en el 9%, al talón en el 8% y a otras localizaciones en el resto de los pacientes. Del total, 80 colgajos tuvieron buena evolución (74%), 11 sufrieron dehiscencia mayor (10,2 %), 13 dehiscencia menor (12%) y 4 necrosis (3,7 %). Los resultados confirman que el colgajo en cono es versátil, reproducible, sencillo y seguro de realizar, y permite al cirujano plástico resolver problemas quirúrgicos complejos de forma muy segura y a bajo costo.

Despite its robustness the Switched Reluctance Motors (SRMs) present some inconvenient drawbacks as a major torque ripple, vibration and acoustic noise when compared to other types of motors. These characteristics are usually related to factors such as the salient poles in the stator and in the rotor, the switched feeding and the control strategy imposed by the electronic converter. In this paper a Special Switched Reluctance Motor for fractional horsepower and high speed hand tool was studied in order to minimize its vibration and torque ripple characteristics. This task was accomplished by the development of a simple and flexible motor drive and the combination of two different commutations strategies: the Three Level Control and the Single Pulse with Overlapping Phase Current. The SRM prototype and its drive were constructed and submitted to several tests with the proposed commutation strategies. In the frequency domain the strategies results were considered satisfactory.

Foram realizados eritrogramas, leucogramas, dosagens séricas de proteínas totais, albumina, globulinas, cálcio, fósforo, magnésio, cloretos, uréia, creatinina, bilirrubina total, direta e indireta e atividade sérica de aspartato aminotransferase (AST), fosfatase alcalina (FA) e gama-glutamiltransferase (GGT) de 56 ovinos afetados por conidiobolomicose e de 371 ovinos sadios provenientes dos mesmos rebanhos dos casos da doença. Os resultados revelaram que os ovinos com conidiobolomicose apresentam anemia arregenerativa normocítica normocrômica, leucocitose com neutrofilia e discreto desvio à esquerda regenerativo, com elevação da relação neutrófilo:linfócito, monocitose moderada, trombocitose, hipoproteinemia (hipoglobulinemia), hipomagnesemia, hipocalcemia e elevação dos teores de fósforo. As atividades séricas de AST e GGT estavam aumentadas e as de FA diminuídas. Não houve alteração nos níveis de uréia e creatinina, mas ocorreu hipoglicemia e hiperbilirrubinemia. Estes resultados podem ser utilizados para estudos experimentais da doença, em ensaios com tratamentos e para identificar casos precoces da enfermidade que não apresentem sinais clínicos. Além disso, os valores encontrados em 371 ovinos deslanados hígidos podem ser utilizados como valores referenciais para este tipo de ovinos na região semi-árida do Brasil.
Hematologic values, serum levels of albumin, globulins, total proteins, calcium, phosphorus, magnesium, chloride, urea nitrogen, creatinine, total, direct and indirect bilirrubin, and serum activities of aspartate aminotransferase (AST), alkalin phosphatase (AF) and gama-glutamyltransferase (GGT) were determined in 56 hair sheep with conidiobolomycosis and 371 healthy hair sheep from the same flocks. Sheep with conidiobolomycosis had nonregenerative, normocytic and normochromic anemia, leucocytosis with neutrophilia and increased nutrophil:lymphocyte rate, moderate monocytosis, moderate thrombocytosis, hypoproteinemia (hypoglobulinemia), hypomagnesemia, hypocalcemia and increased values of phosphorus. Serum activities of AST and GGT were increased and serum activity of FA decreased. Serum values of urea and creatinine were within normal values. Hypoglycemia and hyperbilirrubinemia were also observed. These results can be used for experimental studies with the disease, for treatments trials, and to detect early cases of the disease without clinical signs. Otherwise the hematologic and blood biochemistry values of healthy sheep can be used as reference values for hair sheep in the semi-arid region of Brazil.

The current knowledge of the bromeliad flora of the state of Oaxaca, Mexico is presented. Oaxaca is the Mexican state with the largest number of bromeliad species. Based on the study of 2,624 herbarium specimens corresponding to 1,643 collections, and a detailed bibliographic revision, we conclude that the currently known bromeliad flora for Oaxaca comprises 172 species and 15 genera. All Mexican species of the genera Bromelia, Fosterella, Greigia, Hohenbergiopsis, Racinaea, and Vriesea are represented in the state. Aechmea nudicaulis, Bromelia hemisphaerica, Catopsis nitida, C. oerstediana, C. wawranea, Pitcairnia schiedeana, P. tuerckheimii, Racinaea adscendens, Tillandsia balbisiana, T. belloensis, T. brachycaulos, T. compressa, T. dugesii, T. foliosa, T. flavobracteata, T. limbata, T. maritima, T. ortgiesiana, T. paucifolia, T. pseudobaileyi, T. rettigiana, T. utriculata, T. x marceloi, Werauhia pycnantha, and W. nutans are recorded for the first time from Oaxaca. Collections from 226 (of 570) municipalities and all 30 districts of the state were studied. Among the vegetation types occurring in Oaxaca, oak forest is the richest with 83 taxa, followed by tropical deciduous forest with 74, and cloud forest with 73 species. Species representation and distribution in Oaxaca are analyzed in detail. We also provide a comparison with bromeliad floras of the states of Chiapas, Guerrero, Puebla and Veracruz. The analysis of the species and collections by altitudinal intervals shows that the highest numbers of both ocurre between 1,500 and 2,000 m, with the number of species markedly decreasing above 2,500 m.
Se presenta el estado actual del conocimiento de la flora bromeliológica del estado de Oaxaca, México. La entidad ocupa el primer lugar en el país en cuanto a número de especies de Bromeliaceae se refiere. Los resultados obtenidos de la revisión de 2,624 ejemplares herborizados, correspondientes a 1,643 colectas, así como la revisión de bibliografía especializada, muestran que en el estado están presentes 172 especies agrupadas en 15 géneros. Bromelia, Fosterella, Greigia, Hohenbergiopsis, Racinaea y Vriesea tienen representados a todos sus taxa mexicanos. Se registran por primera vez para el estado: Aechmea nudicaulis, Bromelia hemisphaerica, Catopsis nitida, C. oerstediana, C. wawranea, Pitcairnia schiedeana, P. tuerckheimii, Racinaea adscendens, Tillandsia balbisiana, T. belloensis, T. brachycaulos, T. compressa, T. dugesii, T. foliosa, T. flavobracteata, T. limbata, T. marítima, T. ortgiesiana, T. paucifolia, T. pseudobaileyi, T. rettigiana, T. utriculata, T. x marceloi, Werauhia pycnantha y W. nutans. Se registraron colectas para 226 municipios de los 570 y para el total de los distritos (30) en los que está dividido políticamente el estado. Se hizo una comparación de la flora bromeliológica de Oaxaca con la de Chiapas, Guerrero, Puebla y Veracruz. De los tipos de vegetación presentes, el Bosque de Quercus es el que presenta mayor riqueza de taxa (83), seguido por el Bosque Tropical Caducifolio (74) y el Bosque Mesófilo de Montaña (73). El análisis del número de especies y de colecciones por intervalo altitudinal muestra que las cantidades más altas, tanto de colectas como de especies, se concentran entre los 1,500 y los 2,000 m s.n.m., disminuyendo claramente por arriba de los 2,500 m.

Peginterferon alfa plus ribavirin is currently the treatment of choice for chronic hepatitis C. Peginterferon alfa-2a (40KD) plus ribavirin has given an overall sustained virological response of 18% in F3/F4 previous nonresponder US patients. We evaluated the effectiveness of peginterferon alfa-2a (40KD) plus ribavirin in Brazilian patients who were relapsers or nonresponders to previous interferon-based therapy. One-hundred-thirty-four patients with biopsy-proven chronic hepatitis C, HCV RNA positive, elevated ALT and who were either relapsers (n=37) or nonresponders (n=97) to at least 24 weeks of conventional interferon/ribavirin therapy were retreated with peginterferon alfa-2a (40KD) 180mg/qw and ribavirin 800mg bid for 48 weeks. Efficacy was assessed as virological response (defined as undetectable HCV RNA) at the end of treatment (EoT) and at the end of follow-up (SVR - Sustained Virological Response). Safety assessments consisted of clinical and laboratory evaluations. In the patient sample, 72% were genotype 1 and 34% were cirrhotic. In an intention-to-treat analysis, relapser patients showed 78% EoT response and 51% SVR. Nonresponders showed 57% EoT response and 26% SVR. Positive predictive factors of SVR were non-1 genotype and relapser state. Six percent of the patients interrupted treatment because of adverse events and 45% had dose reduction (mainly associated with leucopenia and anemia). Brazilian patient relapsers and nonresponders to conventional interferon and ribavirin treatment can achieve a sustained virological response when retreated with peginterferon alfa-2a (40KD) and ribavirin. The safety profile is similar to that of naive patients.

Foram aplicados, o teste de Mantoux e uma prova intradérmica dupla de tuberculina (PID), em 131 pacientes hospitalizados para elucidação de diagnóstico, sendo os resultados comparados estatisticamente com o diagnóstico final obtido por métodos clínicos, cirúrgicos e laboratoriais. O teste de Mantoux lido às 72 h seguido de nova aplicação de PPD no mesmo local, sendo lida a nova reação após 24 h constitui a prova intradérmica dupla (PID), sendo o resaltado final obtido da diferença em mm entre a primeira e a segunda leitura. A análise estatística mostrou que a PID é melhor que o teste de Mantoux, com menos erros, menos reações falsas-positivas, probabilidade nula de dar falsos-negativos, maior sensibilidade e maior especificidade. Concluiu-se que a PID pode ser usada em elucidação de diagnóstico e em inquéritos de saúde pública em tuberculose.
The Mantoux test and a double intradermal tuberculin test (PID), were carried out on 131 patients hospitalized for diagnostic elucidation. Comparison was made between the results of the two intradermal tests and the final diagnosis, obtained by clinical, surgical and laboratory methods, and the data were submitted to statistical analysis. Measuring Mantoux reaction after 72 h, and injecting a new intradermal dose of PPD at exactly the same point and repeating the reading after another 24 h, the difference in size (mm) between the first and second readings may be interpreted in three different ways: 1) A difference of less than 3 mm between the two readings: nill statistical probability of patient with tuberculosis. 2) A difference of 3 mm or more, with maximal reaction diameter of 9 mm: indecisive result; patient probably without tuberculosis, however it is suggested that a new PID should be carried out after another 90 days. 3) A difference of 3 mm or more, with maximal reaction of 10 mm or more: patient probably has tuberculosis. The statistical analysis showed that the PID test is better than the Mantoux test, presenting fewer errors, less false-positive results, nill probability of false-negative results, better sensibility and specificity. The conclusion was drawn that the PID is a test that can be used in diagnostic elucidation and publici health surveys on the incidence of tuberculosis.
