      La pirater√≠a, el contrabando y la producci√≥n de marihuana en Paraguay, marcaron su actividad dentro de lo il√≠cito. Uno de los casos m√°s extremos sucede en la ciudad de Pedro Juan Caballero, fronteriza con Ponta Por√£, Brasil. Aquella localidad se impuso como un claro ejemplo de coexistencia de la racionalidad legal, las reglas neo-patrimonialistas y la rivalidad entre grupos internacionales del narcotr√°fico. Lejos de tratarse de un problema de ausencia de Estado, la expansi√≥n del tr√°fico de drogas estuvo enmarcada en un tipo de orden clandestino, propiciado desde la legalidad ‚Äďpol√≠ticos, policias, funcionarios p√ļblicos‚Äď, que produjo roles y normas de convivencia social. A trav√©s de entrevistas cualitativas con cuatro informantes clave ‚Äďun politico nacional, una autoridad local y dos exagentes antidrogas‚Äď se investig√≥ la l√≥gica de dicho orden, realizando un an√°lisis del surgimiento y la consolidaci√≥n del narcotr√°fico en Pedro Juan Caballero.  Paraguay is a country historically linked to smuggling, piracy and drug trafficking. Pedro Juan Caballero is an example of coexistence of legal rationality, neo-patrimonialist rules and rivalry for the control of illegal markets. Far from being a problem of absence or weakness of the State, the expansion of drug trafficking in this area is framed in a kind of clandestine order that produces alternative roles and rules, propitiated funda-mentally from the legality ‚Äďpoliticians, policemen and public officials‚Äď. Through in-depth interviews with four informants -a national politician, a local authority and two anti-drug agents-, this paper investigated the logic of this order, conducting an analysis of the various actors, functions and benefices of the drug universe in Pedro Juan Caballero

The time-dependent Schrodinger equation is solved by using the split-operator technique to determine the photocurrent generated by the electron movement through the biased MQW system. An analysis of the energy shifts in the photocurrent spectra reveals interesting features coming from the contributions of localized and extended states on the MQW system. The photocurrent signal is found to increase for certain values of electric field, leading to the analog of the negative conductance in resonant tunneling diodes. The origin of this enhancement is traced to the mixing of localized states in the QWs with those in the continuum. This mixing appears as anticrossings between the localized and extended states and the enhanced photocurrent can be related to the dynamically induced Landau-Zener-Stuckelberg-Majorana transition between two levels at the anticrossing.In this paper the photon-assisted electron motion in a multiquantum well (MQW) semiconductor heterostructure in the presence of an electric field is investigated.

    The devaluation of medicinal plants from the early twentieth century made him lose a lot of existing knowledge about the herbs that can be of some benefit to health. This knowledge is returning from scientific knowledge, making the ethnobotanical knowledge to be tapped only for exploratory studies. The rescue of this knowledge among family, through the student of elementary school, is one way to save this knowledge. Thus, this study aims to rescue the cultural knowledge of medicinal plants and their importance to health. To carry out this research we worked with the methodology of action research, in which it was possible to draw a work plan with students of the sixth grade of elementary school. The action plan was effective from lectures with use of data projectors, practical classes, activities with family, and presentation of the work. It was understood that the collective work strengthens the community‚Äôs relationship with the school, approaching social subjects and developing a sense of responsibility and cooperation in schools, always highlighting the relationship of medicinal plants to the health of the population.A desvaloriza√ß√£o das plantas medicinais desde o in√≠cio do s√©culo XX fez com que se perdesse muito do conhecimento j√° existente sobre as ervas que podem trazer algum benef√≠cio √† sa√ļde. Este conhecimento est√° retornando a partir do conhecimento cient√≠fico, fazendo com que o conhecimento etnobot√Ęnico seja aproveitado apenas para estudos explorat√≥rios. O resgate deste conhecimento no meio familiar, atrav√©s do aluno do ensino fundamental, √© uma das formas de recuperar esse conhecimento. Desta forma, este trabalho tem como objetivo resgatar os conhecimentos culturais sobre as plantas medicinais e sua import√Ęncia para a sa√ļde. Para efetivar esta pesquisa trabalhou-se com a metodologia da pesquisa-a√ß√£o, pela qual foi poss√≠vel tra√ßar um plano de trabalho com alunos do sexto ano do ensino fundamental. O plano de a√ß√£o se efetivou a partir de aulas expositivas com uso de datashow, aula pr√°tica, atividades com as fam√≠lias e apresenta√ß√£o dos trabalhos. Entendeu-se que o trabalho coletivo fortalece a rela√ß√£o da comunidade com a escola, aproximando os sujeitos sociais e desenvolvendo o senso de responsabilidade e de coopera√ß√£o nas escolas, sempre destacando a rela√ß√£o das plantas medicinais com a sa√ļde da popula√ß√£o

    Overactive bladder-18 years - Part II

    Traditionally, the treatment of overactive bladder syndrome has been based on the use of oral medications with the purpose of reestablishing the detrusor stability. The recent better understanding of the urothelial physiology fostered conceptual changes, and the oral anticholinergics - pillars of the overactive bladder pharmacotherapy - started to be not only recognized for their properties of inhibiting the detrusor contractile activity, but also their action on the bladder afference, and therefore, on the reduction of the symptoms that constitute the syndrome. Beta-adrenergic agonists, which were recently added to the list of drugs for the treatment of overactive bladder, still wait for a definitive positioning - as either a second-line therapy or an adjuvant to oral anticholinergics. Conservative treatment failure, whether due to unsatisfactory results or the presence of adverse side effects, define it as refractory overactive bladder. In this context, the intravesical injection of botulinum toxin type A emerged as an effective option for the existing gap between the primary measures and more complex procedures such as bladder augmentation. Sacral neuromodulation, described three decades ago, had its indication reinforced in this overactive bladder era. Likewise, the electric stimulation of the tibial nerve is now a minimally invasive alternative to treat those with refractory overactive bladder. The results of the systematic literature review on the oral pharmacological treatment and the treatment of refractory overactive bladder gave rise to this second part of the review article Overactive Bladder - 18 years, prepared during the 1st Latin-American Consultation on Overactive Bladder.Univ Fed Sao Paulo, EPM, Sao Paulo, SP, BrazilUniv Sao Paulo, Dept Urol, BR-05508 Sao Paulo, SP, BrazilFac Med ABC, Dept Urol, Sao Paulo, SP, BrazilUniv Los Andes, Dept Urol, Bogota, ColombiaEscuela Med Mil, Dept Urol, Mexico City, DF, MexicoHosp Clin Jose San Martin, Catedra Urol, Buenos Aires, DF, ArgentinaMae de Deus Ctr Hosp, Dept Urol, Porto Alegre, RS, BrazilUniv Fed Ciencias Saude Porto Alegre, Porto Alegre, RS, BrazilAC Camargo Hosp, Dept Urol, Sao Paulo, SP, BrazilHosp Clinico Fuerza Area Chile, Santiago, ChileInst Mexicano Seguro Social, Mexico City, DF, MexicoHosp Souza Aguiar, Dept Urol, Rio De Janeiro, RJ, BrazilComplejo Med Policial Churruca Visca, Serv Urol, Buenos Aires, DF, ArgentinaCtr Policlin Valencia Vina, Valencia, VenezuelaHosp Pablo Tobon Uribe, Medellin, ColombiaClin Indisa, Serv Urol, Providencia, ChileCtr Reabilitacao & Readaptacao Dr Henriqe Santill, Goiania, Go, BrazilHosp Univ Caracas, Serv Urol, Caracas, VenezuelaUniv Fed Ceara, Div Urol, Fortaleza, Ceara, BrazilUniv Fed Sao Paulo, EPM, Sao Paulo, SP, BrazilWeb of Scienc

    Overactive bladder syndrome is one of the lower urinary tract dysfunctions with the highest number of scientific publications over the past two decades. This shows the growing interest in better understanding this syndrome, which gathers symptoms of urinary urgency and increased daytime and nighttime voiding frequency, with or without urinary incontinence and results in a negative impact on the quality of life of approximately one out of six individuals - including both genders and almost all age groups. The possibility of establishing the diagnosis just from clinical data made patients' access to specialized care easier. Physiotherapy resources have been incorporated into the urological daily practice. A number of more selective antimuscarinic drugs with consequent lower adverse event rates were released. Recently, a new class of oral drugs, beta-adrenergic agonists has become part of the armamentarium for Overactive Bladder. Botulinum toxin injections in the bladder and sacral neuromodulation are routine modalities of treatment for refractory cases. During the 1st Latin-American Consultation on Overactive Bladder, a comprehensive review of the literature related to the evolution of the concept, epidemiology, diagnosis, and management was conducted. This text corresponds to the first part of the review Overactive Bladder 18-years.Univ Fed Sao Paulo, EPM, Rua Dr Oscar Monteiro Barros 617-141, BR-05641010 Sao Paulo, SP, BrazilUniv Sao Paulo, Dept Urol, BR-05508 Sao Paulo, SP, BrazilFac Med ABC, Dept Urol, Sao Paulo, SP, BrazilUniv Los Andes, Dept Urol, Bogota, ColombiaEscuela Med, Dept Urol, Mexico City, DF, MexicoHosp Clin Jose San Martin, Catedra Urol, Buenos Aires, DF, ArgentinaMae de Deus Ctr Hosp, Dept Urol, Porto Alegre, RS, BrazilUniv Fed Ciencias Saude Porto Alegre, Porto Alegre, RS, BrazilAC Camargo Hosp, Dept Urol, Sao Paulo, BrazilHosp Clin Fuerza Area Chile, Santiago, ChileInst Mexicano Seguro Social, Mexico City, DF, MexicoHosp Souza Aguiar, Dept Urol, Rio De Janeiro, RJ, BrazilComplejo Med Policial Churruca Visca, Serv Urol, Buenos Aires, DF, ArgentinaCtr Policlin Valencia Vina, Valencia, VenezuelaHosp Pablo Tobon Uribe, Medellin, ColombiaClin Indisa, Serv Urol, Providencia, ChileCtr Reabilitacao & Readaptacao Dr Henriqe Santill, Goiania, Go, BrazilHosp Univ Caracas, Serv Urol, Caracas, VenezuelaUniv Fed Ceara, Div Urol, Fortaleza, Ceara, BrazilUniv Fed Sao Paulo, EPM, Rua Dr Oscar Monteiro Barros 617-141, BR-05641010 Sao Paulo, SP, BrazilWeb of Scienc
