Abstract: Em fun o de históricos obtidos, no presente estudo tentou-se reproduzir, em bovinos, fotossensibiliza o e/ou aborto com as favas de Enterolobium spp (Leg. Mimosoi-deae). As favas de E. contortisiliquum e E. timbouva ("tamboril" ou "timbaúba"), de diversas procedências, inclusive as colhidas durante dois surtos de intoxica o caracterizados por fotossensibliliza o e aborto, foram administradas em doses únicas e repetidas, a bovinos jovens e a vacas em gesta o. Em todos os experimentos realizados, a resposta à ingest o das favas independentemente da procedência, sempre foi caracterizada por diarréia e diminui o do apetite, passageiras. Também ficou evidente que os animais mostram menor sensibilidade, à medida que ingerem as favas seguidamente. Os experimentos n o revelaram possíveis fatores envolvidos ou eventuais condi es necessárias para que as favas de Enterolobium contortisiliquum e E. timbouva causem fotossen-sibliza o e/ou aborto.

Abstract: the pods of enterolobium spp (leg.mimosoideae) are said to cause photsensitivity and abortion in cattle. the pods of e. contortisiliquum and e. timbouva ("tamboril" or "timbaúba"), collected at various localities, in two occasions during outbreaks of photosensitization and abortions, were fed in single and repeated doses to young bovines and to cows in calf. in all experiments the animals showed only diarrhoea and loss of apetite, as it had been already seen in previous experiments with e. contortisiliquum performed in fortaleza, northeastern brazil. also it was seen again that the animals become tolerant to the toxicity of the pods if they get successive doses. the experiments did not reveal possible conditions necessary for the pods of enterolobium contortisiliquum and e. timbouva to cause photosensitization and/or abortion.
Low power current sources for bioimpedance measurements: A comparison between Howland and integrated CMOS OTA circuits
Pedro Bertemes-Filho,Volney Coelho Vincence,Marcio S Santos,Ilson Xavier Zanatta
Journal of Electrical Bioimpedance , 2012, DOI: 10.5617/jeb.380
Abstract: Electrical Bioimpedance Analysis has been widely used as a non-invasive technique for characterizing tissues. Most systems use a wideband and a high precision instrumentation, specially the current source. The objective of this work is to compare the Howland circuit with three OTA-based floating voltage controlled current sources. The results show that both Current Conveyor and class-AB OTA have a wider output current frequency response and both output impedance is 226 % bigger than the Howland circuit at 1 MHz. The class-AB OTA circuit presents a power consumption of 4.6 mW whereas 1.6 mW for the Current Conveyor. The results might be useful for cell impedance measurements and for very low power bioimpedance applications.
SIDA y otras afecciones de transmisión sexual en presidiarias de la región central de Venezuela

Abstract: Objetivo: Investigar la presencia del síndrome de inmunodeficiencia adquirida y otras afecciones de transmisión sexual en presidiarias de la región central de Venezuela. Método: Estudio analítico, prospectivo, en 265 internas a las cuales se les realizó Papanicolaou, prueba de Schiller y biopsia cervical cuando fue necesaria; así como también, pesquisa de enfermedades de transmisión sexual y encuesta sobre sus hábitos sexuales, en el período marzo a junio de 2000. Ambiente: Cárceles de Tocorón, Tocuyito y el Instituto Nacional de Orientación Femenina. Resultados: La edad de las primeras relaciones sexuales ocurrió a un promedio de 16,75 a os. Se observó una ligera tendencia a la promiscuidad sexual en 33,96 % de los casos. El patrón sexual de las internas resultó netamente heterosexual (89 %). La presencia de sífilis fue muy elevada (117/1000 habitantes) al compararla con la morbilidad nacional que es de 3,51/1 000 habitantes; igualmente, la morbilidad por síndrome de inmunodeficiencia adquirida, resultó en 377/1 000 la cual fue elevada si se compara con la nacional de 2,5/1 000. Conclusiones: Este es el primer estudio prospectivo nacional donde se evaluó la presencia de síndrome de inmunodeficiencia adquirida y otras afecciones de transmisión sexual en presidiarias de la región central del país. Además de los ligeros índices de promiscuidad encontrados, también se evidenció una alta morbilidad en sífilis y en el síndrome de inmunodeficiencia adquirida. El Ministerio del Interior y Justicia a través de sus dependencias de salud debe vigilar y corregir esta problemática.

O ESTADO ENTRE O LIBERALISMO E O NEOLIBERALISMO
ROCHA, Manoel Ilson Cordeiro
Nucleus , 2008,
Abstract: is not only the rescue of the principles of the minimum State and of the marketfreedom, it differentiates for its actors and the contemporaries conditions of the power. She is necessary tocontextualize these actors and these conditions defin it and compares it with classic liberalism. This definitionimplies in identifying the orientation of the international capital the State, restricting its intervention in economyand reducing the national barriers to the transit of merchandises and capitals. Under the globalization heading,it congregates the phenomena of internationalization of economy and under the heading of neoliberalism, thereforms of the State in its legal systems, to deal the global economy.O neoliberalismo n o é apenas o resgate dos princípios do Estado mínimo e da liberdade de mercado;diferencia-se pelos seus atores e pelas condi es contemporaneas do poder. é preciso contextualizar estes atorese estas condi es para defini-lo e compará-lo com o liberalismo clássico. Esta defini o implica em identificara orienta o do capital internacional para o Estado, restringindo a sua interven o na economia e reduzindo asbarreiras nacionais ao transito de mercadorias e capitais. Sob o título de globaliza o, se reúnem os fen menos deinternacionaliza o da economia e, sob o título de neoliberalismo, as reformas do Estado em seus ordenamentosjurídicos, para atender à economia globalizada.
PóS-MODERNIDADE E CRISE DO ESTADO MODERNO: O OCASO DO CONSTITUCIONALISMO LIBERAL
ROCHA, Manoel Ilson Cordeiro
Nucleus , 2009,
Abstract: The sunset of the constitucionalismo is resulting from the transition for to powders-modernitythat, between other phenomena, it is realized by a new society that reduces his political universe because ofadopting a speech of efficiency and individualism. In this environment the immediate hypothesis is of crisis forthe practice of citizenship, in his sense classic and definite in the democratic liberal constitutions. But the formatof the Modern, cohesive and uniform State around the concept of sovereignity, also is today questioned and theconstitution, like document and instrument that symbolizes this power, it is hypothetically discredited. But themodern constitution, with his symbols of ceremony, rationality and it forces, it is a tangible and importantinstrument of resistance. When the constitution allied to the idea of which there is inherent in the society a set ofbeginnings that governs it, it will survive under a new perspective. A perspective that has to consider theglobalized world and the bases of the powders-modernity.O ocaso do constitucionalismo é decorrente da transi o para a pós-modernidade que, entreoutros fen menos, é percebido por uma nova sociedade que reduz o seu universo político por adotar umdiscurso de eficiência e individualismo. Neste ambiente a hipótese imediata é de crise para o exercício dacidadania, no seu sentido clássico e expresso nas constitui es democráticas liberais. Mas o formato do EstadoModerno, coeso e uniforme em torno do conceito de soberania, também é hoje questionado e a constitui o,como documento e instrumento que simboliza este poder, é hipoteticamente desacreditada. Mas a constitui omoderna, com os seus símbolos de solenidade, racionalidade e for a, é um instrumento palpável e importante deresistência. Aliada à idéia de que é inerente à sociedade um conjunto de princípios que a rege, a constitui osobreviverá sob uma nova perspectiva. Uma perspectiva que tem que considerar o mundo globalizado e osfundamentos da pós-modernidade.
Espectacularidad y comportamientos de masa: El problema de la autoría (externa)
Gutiérrez Brito, Jesús;
Revista mexicana de sociología , 2012,
Abstract: this article discusses the problem of the political and social authorship in the collective spontaneous behaviors, and the facul-ty that the crowds and/or multitudes have to perform on own initiative responsibly and without influence or external manipulation. the current analysis approaches the formal problems than entails to the fact to assume this type of collective behaviors, but also some difficulties related with the explanation of theimitation and his auto-reflexive potential. the end purpose of this analysis leads to present espectacularidad"s concept like instrument to redefine and to advance new solutions to the problem of the disavowal in these social formations once historically were regarded as irrationalists and/or instinctive.
