Abstract: Three 10 μg doses of the recombinant hepatitis B vaccine, manufactured by Instituto Butantan by original technology, were administered in a adult population, mean age 30 years old, following the 0, 1 and 6 months schedule immunization. The clinical trial was considered satisfactory in terms of immunogenicity (anti-HBs titers between 17.5-29500 IU/l, seroconversion 95.3%) and reactogenicity (no incapacitating side effects)
Trichomycterus dali: a new highly troglomorphic catfish (Silurifomes: Trichomycteridae) from Serra da Bodoquena, Mato Grosso do Sul State, Central Brazil

Neotropical Ichthyology , 2011, DOI: 10.1590/S1679-62252011000300003
Abstract: trichomycterus dali, new species, is described from flooded limestone caves in serra da bodoquena karst area, state of mato grosso do sul, central brazil. the new species is diagnosed by a unique character in the genus, the presence of conspicuous, ridge-like adipose folds lining dorsally throughout the body. trichomycterus dali can be further distinguished readily from epigean congeners by the reduction of eyes and skin pigmentation (except for t. gorgona), and from remaining congeners (i.e., all hypogean plus t. gorgona) by the total loss of eyes, not visible externally (except for t. sandovali and t. spelaeus). other diagnostic features includes very long barbels, especially the nasal (99.3-143.5% hl) and the maxillary (97.0-131.3% hl), pectoral-fin ray count reaching i,9 and a unique cranial fontanel with a conspicuous constriction on the meeting point of supraoccipital and the two frontal bones. the troglobitic status of the species is suggested by the presence of troglomorphisms on an advanced degree, especially the reduction of skin pigmentation, the total loss of eyes and the enlarged barbels. in addition, the presence of a well developed adipose fold in adults may indicate a distinctive adaptation acquired by neoteny to withstand the food scarce conditions of its hypogean habitat.

Abstract: O desenvolvimento de fontes de soldagem com processos derivativos MIG/MAG com transferência por curto-circuito, também conhecidos como curto-circuito controlado, tem-se tornado uma tendência na busca de soldas de qualidade e produtividade, principalmente na uni o de dutos, pois acredita-se que, o controle da corrente permite melhorar a transferência metálica, proporcionando estabilidade ao processo de soldagem e a po a de fus o. Neste contexto, o objetivo deste trabalho é determinar envelope operacional e estabelecer vantagens e limita es operacionais dos processos MIG/MAG com transferência por curto-circuito convencional e derivativos (STT - SurfaceTensionTransfer, RMD - Regulated Metal Deposition e CMT - Cold Metal Transfer), para a uni o de dutos de a o carbono com diametro nominal de 2 "e parede fina com passe único, nas progress es ascendente e descendente. Para tal, optou-se por variar os parametros de regulagem de cada processo e a velocidade de alimenta o do arame, além das técnicas de soldagem, procurando manter a mesma quantidade de material depositado por comprimento de solda. Os resultados encontrados mostraram que o curto-circuito convencional apresentou um envelope operacional constante para a progress o ascendente e para a descendente quanto ao número de ensaios. Ao passo que, o STT e o RMD apresentaram um maior envelope operacional na progress o descendente. Por outro lado, o CMT, com envelope operacional maior na ascendente, trabalha com valores de tens o de soldagem muito mais baixos, o que justifica o baixo aporte térmico do processo. The development of power sources towards the MIG/MAG derivative processes with short-circuit metal transfer (also known as controlled short-circuit) has become a trend in the search for high productivity and high quality weldments, especially in pipe welding. It is believed that the control of current achieved in such processes improves the metal transfer, reaching stability on both process and weld pool. Therefore, this work aims to establish operational envelopes and also both advantages and limitations of MIG/MAG processes with conventional short-circuit transfer and derivatives (STT, RMD and CMT) for pipe welding. The weldments were carried out in thin-wall carbon-steel pipes with nominal diameter of 2 " using single pass and both upward and downward progressions. The parameter sets for each process were varied together with wire-feed speed, keeping the same amount of deposited material, enough to fill up the joint in a single-pass bead. The results show that the conventional short-circuit MIG/MA

Abstract: La hidatidosis constituye un serio problema de Salud Pública en la Provincia de Río Negro, Argentina. Los factores que han motivado esta situación incluyen una economía rural basada en la ganadería ovina extensiva, bajas condiciones socioculturales en una porción importante de la población rural, hábitos de faenamiento domiciliario de ovinos adultos para consumo humano con entrega de las vísceras resultantes del acto para consumo de los perros e infraestructura de faena en peque as comunidades rurales altamente deficiente. Esta situación ha promovido la instrumentación de un programa de control basado en la desparasitación canina sistemática con praziquantel, la vigilancia con arecolina, la educación sanitaria, el control de faena, la legislación y la atención de las personas. El programa, puesto en marcha en 1980, cubrió inicialmente con acciones sistemáticas 51.479 km2, alcanzándose en 1992 120,013 km2 bajo control. 11.915 canes rurales han recibido 1,870,423 comprimidos de praziquantel con coberturas que en promedio fueron del 65%. Se efectuaron 21.444 controles de materia fecal canina mediante la dosificación con bromhidrato de arecolina, (control anual del 11,2% de los canes bajo programa). La prevalencia equinococcósica inicial era de 41,5%, siendo en 1996 del 2,9%. La hidatidosis ovina, por su parte, presenta una disminución acentuada de la prevalencia, ubicándose en 1996 en el 5,5%. En relación a hidatidosis humana, 1,720 casos nuevos fueron diagnosticados en toda la provincia en el período 1980/1996, el 31,4% de los cuales correspondieron a infectados asintomáticos, mediante encuestas serológicas o ecográficas (48.826 encuestas serológicas a población escolar y a pobladores rurales adultos y 2.762 encuestas ultrasonográficas). El número de casos humanos nuevos en el grupo de edad 0-10 a os presenta una disminución del 77% desde la puesta en marcha del programa. Por el contrario, zonas no tratadas muestran una tendencia estable en la aparición de casos humanos nuevos. En el período 1980/1986 se produjeron 581 casos nuevos en las áreas bajo programa, mientras que en el período 1990/1996 el número de casos nuevos fue de 275. Las encuestas ultrasonográficas en población asintomática, por su parte, arrojaron tasas de positividad del 5,5% (1984), 4,1% (1986) y 2,1% (1996). El modelo desarrollado, basado en una estructura de ejecución descentralizada, con activa participación comunitaria, selección de tecnologías sencillas y enfoque de riesgo; sustentado en el tiempo sobre la base de una firme decisión política de continuidad programática y a su bajo

Abstract: Fed intake and milk production of Holstein-Zebu crossbred cows, grazing Napier grass (Pennisetum purpureum) (NAP), Brachiaria decumbens (BRA) and Guinea grass (Pannicum maximum) (COL) and supplemented with four kg of concentrate, were evaluated in a double Latin square (3x3). Fecal production and feed intake were calculated using Cr2O3 and in vitro digestibility. Dry mater intake (DMI) was similar among forages (18kg/cow) which represented 2.72%; 2.84% and 2.96% of the live weight for NAP, BRACH and COL respectively. The intake per unit of metabolic size (g DM/kg0.75) was 130 for NAP, 135 for BRACH and 145 for COL. The intake of BRACH resulted in lower milk production (14,4kg) than NAP (15,5kg) and COL (16,1Kg). Grasses did not affected the milk composition which showed 4,03% of fat, 2,46% of protein and 12,42% of total solids. It was concluded that NAP, BRACH and COL are good alternatives for milk production in grazing systems. KEY WORDS: Brachiaria decumbens, Guinea grass, Panicum maximum, Napier, Pennisetum purpureum. Realizou-se a avalia o do consumo de alimentos e da produ o de leite de vacas mesti as pastejando piquetes de capim Napier (Pennisetum purpureum) (NAP), Brachiaria decumbens (BRA) e Coloni o (Pannicum maximum) (COL) e suplementadas com quatro kg de concentrado em um esquema de quadrado latino (3x3) duplo. Calcularam-se a produ o fecal e o consumo de alimentos com o auxílio do Cr2O3 e da digestibilidade in vitro. O consumo diário de MS foi semelhante entre as forragens (18kg/vaca), as quais representaram 2,72%; 2,84% e 2,96% do p.v. para o NAP, BRACH e COL, respectivamente. O consumo por unidade de tamanho metabólico (g MS/kg0,75) foi de 130 para o NAP, 135 para a BRACH e 145 para o COL. A ingest o de BRACH resultou em menor produ o de leite (14,4Kg) em compara o ao NAP (15,5kg) e COL (16,1kg). Verificou-se que as espécies forrageiras n o influíram na composi o do leite das vacas, o qual apresentou 4,03% de gordura, 2,46% de proteína e 12,42% de extrato seco total. Concluiu-se que os capins NAP, BRACH e COL apresentam-se como boas alternativas para a produ o de leite a pasto.

Palavra de coca e de tabaco como "conhecimento tradicional": cultura, política e desenvolvimento entre os uitoto-murui do rio Caraparaná (CO)
Pereira, Edmundo;
Mana , 2011, DOI: 10.1590/S0104-93132011000100004
Abstract: throughout 2000 and 2001 the uitoto-murui communities of the cara paraná river were mobilized by a debate on the notion of 'development.' meetings were held between the indigenous population (including both local villagers and representatives of national organizations) and the non-indigenous population (government officials, ngos and the military) to discuss the theme with the aim of producing 'diagnoses' and 'projects.' as part of this context, the san rafael village- led by cacique don ángel ortiz and the local cabildo or council- proposed a project based on the 'knowledge' acquired from nightly rounds of dialogue and ritual consumption of coca and tobacco, culminating in a corpus of symbolic, ethico-moral and material knowledge denominated 'the word of coca and tobacco' (jiibina uai diona uai). this body of knowledge (spanning from the mytho-cosmological to the medicinal-therapeutic and including forms of governance) can be traced to the sociocultural configurations lived through by indigenous peoples from the region between the caquetá and putumayo rivers (whose symbolic epicentres are coca and tobacco), especially after the 1930s with the end of the colombia-peru war and the debt-bondage system associated with the rubber trade. in the heat of the debates, the notion of 'development' therefore acquired 'indigenous' contours, becoming read and articulated on the basis of local 'uses and customs,' as indeed required by colombia's 1991 constitution. likewise, in response to the demands made from the development area, a concise outline of 'the word of coca and tobacco' was also presented.
GENERACIóN DE BANDAS DE FRECUENCIAS PERMITIDAS EN LíNEAS DE TRANSMISIóN DUAL CON CORRELACIóN DE LARGO ALCANCE EN EL DESORDEN
Lazo,Edmundo;
Ingeniare. Revista chilena de ingeniería , 2008, DOI: 10.4067/S0718-33052008000300007
Abstract: in this work we study the behavior of the allowed frequencies in the dual transmission line when the values of capacitances are distributed according to a disordered sequence with long-range correlation. for each frequency ω we use the lyapunov exponent λ(ω) as a tool to discriminate between a transmitting line and a filtering one. when the dual line has a periodic distribution of capacitances, a typical scheme of permitted bands and forbidden bands (gaps) appears. for the random case every signal is filtered. in this article we analyze the effect of long-range correlation, concluding that two cases can appear, depending on the kind of correlation used: a) there exist only a finite number of specific frequencies for which the signal is propagated, or b) there is a continuous band of propagating frequencies. the appearing of continuous bands is a very important result, since the existence of correlated disorder is a condition necessary but not sufficient to the appearing of propagating frequencies. understanding the mechanisms that describe the transition from a forbidden frequency to an allowed frequency opens the possibility of manufacturing electronic devices where this transition is relevant.
The shape of the human lumbar vertebral canal
Zarzur, Edmundo;
Arquivos de Neuro-Psiquiatria , 1996, DOI: 10.1590/S0004-282X1996000300014
Abstract: literature on the anatomy of the human vertebral column characterizes the shape of the lumbar vertebral canal as triangular. the purpose of the present study was to determine the precise shape of the lumbar vertebral canal. ten lumbar vertebral columns of adult male cadavers were dissected. two transverse sections were performed in the third lumbar vertebra. one section was performed at the level of the lower border of the ligamenta flava, and the other section was performed at the level of the pedicles. the shape of the lumbar vertebral canal at the level of the pedicles tends to be oval or circular, whereas the shape of the lumbar vertebral canal at the level of the lower border of the ligamenta flava is triangular. thus, the shape of the human lumbar vertebral canal is not exclusively triangular, as reported in the literature. it is related to the level of the transversal section performed on the lumbar vertebra. this finding should be taken into consideration among factors involved in the spread of solutions introduced into the epidural space.

Arquivos de Neuro-Psiquiatria , 1996, DOI: 10.1590/S0004-282X1996000300015
Abstract: background and objectives: this study aimed to evaluate the transverse and longitudinal distensibility of the posterior human lumbar dura mater. results are compared with previous literature on biomechanical property studies. possible clinical implications were also examined. methods:samples of human dural sac were obtained from autopsy studies in three adult male cadavers. dural sac samples were sectioned longitudinally to measure transverse and longitudinal distensibility, thickness and circumference. results:it was recorded that the posterior lumbar dura mater was easily distensible only in the transverse direction. the longitudinal force required to distend and rupture the posterior lumbar dura mater samples is 3.5 to 6.7 times greater than the force to produce a transversal rupture. conclusion: depending on the local cerebrospinal fluid pressure, the documented easier transverse distensibility of the posterior lumbar dura mater may allow greater contact of the lumbar dural sac with the wall of the lumbar verterbral canal. this fact may affect the diffusion of solutions introduced into epidural space.
