Use of Amplatz Cannula through Cystostomy
Authors: Montisci Erica , Serra Simona , Corona Andrea , De Lisa Antonello 
Published: October 2012

Introduction Bladder tamponade is an uncommon complication of post-TURP bleeding and, for its resolution, it may require a long and complex process when conducted transurethrally. Material and methods From 2001 to 2011, 20 patients were treated endoscopically by transurethral combined use of Amplatz percutaneous suprapubic cannula. Blood clots were detected above the average size of 5 cm. The technique has required a transurethral access with resector, dissection and resection of clots. In cases where the techniquet has proved insufficient, an Amplatz cannula was introduced by suprapubic access. The resector allows controlling the technique and a constant irrigation, and is also necessary for the final evaluation of the clinical picture. The procedure has been completed with the application of a suprapubic catheter left in site for 24 hours, together with a transurethral one for 48 hours. Results In all the cases that we treated, the condition was solved between 15 and 25 minutes, and the evacuation of blood clots was entirely performed. There were no complications. The final control by transurethral way allowed executing hemostasis in all cases. The post-TURP vesical tamponade can represent a dramatic event in terms of pain and alteration of renal function for patients with renal insufficiency. The combined technique, which might appear bloody, represents a valid alternative to the classic transurethral endoscopic technique, which still represents the gold standard in the case of small bleeding and not organized blood clots. Conclusions The use of a suprapubic approach with this technique allows for a rapid, efficient and secure resolution of, otherwise, a long and difficultly treatable disease as it is the case with bladder tamponade due to clots for non-neoplastic diseases.

Published: October 2012

Background The first laser employment for the treatment of the cervico-urethral obstructions (CUO) dates back to the early ‘90s. This study begins with the analysis of laser basics in Medicine and has the purpose to weigh pros and cons (and limits as well) of laser use in CUO due to Benign Prostatic Hyperplasia (BPH). That is an ageing man's typical disease and there is a huge need of minimally invasive treatments, because people affected by this kind of illness suffer very often from comorbidities, and that could make traditional surgery quite risky. Aim of the Study The target of this study is the in vivo experimentation of a brand new laser diode, crated to be specifically used in BPH, and to verify its efficacy and safety. Materials and methods The subject of the study is the whole laser diode supply, with its double-band laser source (980 nm + 1470 nm), which gains a 140 W-power and is equipped with Water-Free optical fibers of different kinds of tip. We have tested a conical tip fiber on a standard 24–26 F-resectoscope instead of a standard diathermic loop. The conic fiber optimizes the energy on the treated tissue. We recruited 14 patients with CUO caused by BPH, 56 to 70 years old, with a prostatic volume between 33 and 53 cc, and we treated them with laser surgery using the power of 100–110 W. We considered the operative time, the intra-surgery complications and the specific side effects such as hematuria, pain, catheter removal time and the presence or not of acute urinary retention, in order to evaluate the efficacy and safety of this new technique. Results The possibility of using the same resectoscope as the one used in transurethral resection of prostate (TURP) made everything more comfortable and easy because of the immediate feeling with the new instrument and the actual time of Light Vaporization between 30 and 40 minutes, which is more or less the same time of a standard TURP procedure. Conclusions The idea of a double-band-emitting laser used with conical tip fibers appears to be a great solution in the BPH treatment: it uses the principle of low power density plasma in order to treat bigger prostatic tissue areas but never going in depth. In our clinical results, the efficacy of the double-band-emitting laser source (1470 nm + 980 nm) appears to be similar, but even potentially greater, to the actual surgical laser options (such as HoLEP with Ho:YAG laser and PVP with KTP laser), and it is also similar to traditional TURP.
The Power and Centrality of the Transportation and Warehousing Sector within the US Economy: A Longitudinal Exploration Using Social Network Analysis
Authors: Iyengar Deepak , Rao Shashank , Goldsby Thomas J. 
Published: October 2012

AbstractThis article uses archival panel data over two decades and social network analysis (SNA) to address the question of whether logistics and transportation have become more central to the US economy over time. Unlike traditional measures, SNA goes beyond measuring dyadic relationships and incorporates measures of power, like centrality, closeness, and betweenness that traditional measures fail to capture. Secondary data from the Benchmark Use Input‐Output Tables compiled every five years by the US Bureau of Economic Analysis are examined in the SNA context. Results demonstrate the value of using SNA over conventional dyadic measures to analyze the extended network, especially with respect to the shift of power and centrality over time. The findings demonstrate that while the overall industrial landscape of the United States has become less centralized over time, transportation and warehousing have become increasingly central to the US economy. Thus, the article demonstrates that over time, logistics and warehousing have not only become more powerful, but have gone from being peripheral activities to being increasingly central and important in the larger economy. The article contrasts our findings from the SNA approach with those obtained from conventional (non‐SNA‐based approaches) and highlights the differences in the two approaches.
A Comprehensive Risk Assessment and Evaluation Model: Proposing a Risk Priority Continuum
Authors: Griffis Stanley E. , Whipple Judith M. 
Published: October 2012

AbstractSupply chain risks continue to affect global operations, with no promise of abating in the foreseeable future. While past studies have examined elements of supply chain risk, many have focused on only the likelihood of a risk occurring and/or the impact of the risk. This research outlines a more rigorous risk assessment and evaluation process, one that builds upon the reliability engineering field and includes an additional risk factor, the probability of risk detection. By using the proposed process, managers can create a risk priority continuum, which can lead to the development of better risk mitigation strategies. Given that not all risks are the same, this article provides a tool for assessing and prioritizing risks to enable managers to achieve desired risk prevention levels as well as to offer faster recovery from risks that actually occur.

http://dx.doi.org/10.5902/198464443636 Este estudo teve por objetivo investigar uma política pública destinada à escolarização dos adolescentes autores de ato infracional privados de liberdade na Unidade de Internação Provisória - UIP da Fundação Centro de Atendimento Sócioeducativo ao Adolescente - Fundação CASA, instalada no Núcleo de Atendimento Integrado de Americana - NAIA. Procurou-se analisar e investigar as contribuições do “Projeto Educação e Cidadania” para a inclusão na escola do aluno autor de ato infracional. Para tanto foram entrevistados todos os adolescentes que participaram do projeto, que se encontravam cumprindo medida socioeducativa de liberdade assistida e que haviam voltado a estudar. Também foram entrevistados seus professores, colegas, funcionários e gestores das escolas. Os resultados indicaram que os alunos, após a participação no projeto, se diziam mais preparados para o exercício da cidadania. Porem, tanto eles como os educadores mostraram ter dúvidas em relação à eficácia do projeto no que se refere a sua contribuição para a inclusão escolar. A avaliação feita sobre o projeto não permitiu apontar claramente se ele de fato contribuiu para a permanência daqueles alunos na escola.

<b>Iluminismo pedagógico e educação natural em Jean-Jacques Rousseau</b>
Authors: Wendt Cristiano Eduardo , Dalbosco Claudio Almir 
Published: October 2012

http://dx.doi.org/10.5902/198464444827 O ensaio discute a importância de Jean-Jacques Rousseau para a pedagogia moderna, tendo por base sua obra filosófico-pedagógica Emílio ou Da Educação. Busca apresentar qual o significado do iluminismo pedagógico, bem como, a concepção de educação natural, e as duas grandes novidades trazidas por Rousseau para o campo educacional, a saber, os conceitos de infância e de educação. Nesta perspectiva, analisa as três principais interpretações a que o iluminismo rousseauniano foi submetido ao longo da história: como otimista da razão, primitivista e dialético da razão. Assumindo o pensamento do genebrino como defensor de uma dialético da razão, o ensaio procura refletir sobre os desdobramentos que esta concepção provoca ao seu projeto de educação natural e como reflete no desenvolvimento cognitivo e moral dos infantes. Por fim trata de apresentar duas inovações que Rousseau traz para o campo da educação, a primeira no que diz respeito ao conceito de infância e, a segunda, ao processo pedagógico como um todo, considerando as fases de amadurecimento biológico, cognitivo e moral, nas quais cada criança se encontra.
<b> O lugar da experiência, da cultura e da aprendizagem multimídia na formação de professores </b>
Authors: Fantin Monica 
Published: October 2012

http://dx.doi.org/10.5902/198464444864 Quais os desafios da formação de crianças, jovens e professores hoje? Falar de saberes e competências necessárias para o professor atuar nos cenários atuais implica perguntar em que medida a universidade, os cursos de licenciatura e os centros de formação docente estão se adequando às novas demandas da educação. Ao situar alguns desafios atuais da formação inicial em relação à cultura digital, o artigo enfatiza a importância da experiência, da formação cultural e da multimídia na formação de professores a partir de uma perspectiva culturalista de mídia-educação. Considerando que a mídia-educação é um campo em construção, a transversalidade e a contribuição multidisciplinar dos saberes das ciências, da educação, da comunicação e das artes constituem um “objeto-fronteira”, uma interface que pode interpretar melhor a transformação atual dos conhecimentos e das ferramentas da cultura digital que não se limitam à educação escolar. O texto discute a possibilidade da formação multimídia e suas competências como integração de saberes e contribuições metodológicas provindas de diferentes áreas do conhecimento e da perspectiva das múltiplas linguagens na escola e na cultura. Disso resulta a necessidade de configurar outros espaços para pensar a práxis educativa e formativa e discutir novas formas de mediação cultural nos cenários contemporâneos da formação de professores.
<b>Cenário da pesquisa em artes visuais e as inter-relações com a inclusão: um olhar na produção científica dos anais da ANPAP de 2004 até 2011 </b>
Authors: Nunes Ana Luiza Ruschel 
Published: October 2012

http://dx.doi.org/10.5902/198464445406 Este artigo é continuidade de pesquisa iniciada em 2009, e ampliada em 2011, e objetiva mapear e analisar o cenário da pesquisa em Artes Visuais e a inter-relação com a inclusão social. A abordagem foi quantiqualitativa, a partir das narrativas e discursos presentes nos trabalhos publicados nos anais dos Encontros Nacionais dos Pesquisadores em Artes Plásticas ( ANPAP). Para identificar e analisar as Artes Visuais e suas inter-relações, fez-se um estudo documental por meio das edições dos anais da Anpap, de 2004 até 2011, totalizando 229 produções. Constatamos que a produção científica na área está a cada ano em crescimento. Entretanto, verificou-se que foi a partir de 2006 que houve maior intensidade da pesquisa das Artes Visuais inter-relacionada com a inclusão, ainda que tênue em relação à inclusão social. A partir dessa análise identificamos concepções, tendências e diversidades de problemas de pesquisa das Artes Visuais e inclusão, e pode-se inferir que, nos últimos oito anos, houve maior aprofundamento em relação a concepções e práticas inclusivas, embora tímido diante da totalidade do cenário da produção científica das pesquisas na área de Artes Visuais.

Conceptualiser les faiblesses de la gouvernance mondiale : au-delà de la crise financière
Authors: Held David , Young Kevin L. , Maertens Jan 
Published: October 2012

Comment devrions-nous conceptualiser les faiblesses de la gouvernance mondiale associée à la récente crise financière mondiale ? Nous soutenons que la gouvernance mondiale financière a pu être caractérisée par l’intrication d’un système de communication et de coordination, responsable de quelques réussites majeures. Ses échecs peuvent être conceptualisés à la fois en termes de manque de capacités institutionnelles d’une part, de représentation et de responsabilité d’autre part. Ces problèmes ne sont cependant pas spécifiques au domaine de la finance, et envahissent d’autres domaines tels que les systèmes de sécurité et la gouvernance environnementale mondiale. Ainsi, les défaillances dans la gouvernance financière mondiale peuvent être englobées dans le défi plus vaste qu’impose une gouvernance mondiale, avec des racines et des causes plus profondes que la plupart des études universitaires s’attachent à démontrer.
L’altermondialisme et la revalorisation de la politique extra-parlementaire
Authors: Gheller Frantz 
Published: October 2012

Cet article a pour but d’éclairer sous un nouveau jour le contexte sociopolitique dans lequel se mènent les luttes altermondialistes en attirant l’attention sur deux hypothèses théoriques de la sociologie historique critique. En particulier, il soutient que la sociologie concernée par l’agence transformatrice de l’altermondialisme gagnerait à théoriser davantage la spécificité du capitalisme — une séparation inédite entre l’« économie » et le « politique » — pour dépasser l’analyse conjoncturelle du néolibéralisme et de la démocratie libérale afin de mieux évaluer les processus par lesquels les altermondialistes tentent de changer le monde sans prendre le pouvoir. L’article souligne finalement les hésitations de l’altermondialisme à repolitiser la question de la nature du travail et des relations sociales de propriété, mais conclut néanmoins que l’altermondialisme a le grand mérite de revaloriser une culture politique cosmopolite et extra-parlementaire dépréciée par la démocratie libérale.
Low prevalence of transmitted K65R and other tenofovir resistance mutations across different HIV‐1 subtypes: implications for pre‐exposure prophylaxis
Authors: Chan Philip A , Huang Austin , Kantor Rami 
Published: October 2012

IntroductionTenofovir‐containing regimens have demonstrated potential efficacy as pre‐exposure prophylaxis (PrEP) in preventing HIV‐1 infection. Transmitted drug resistance mutations associated with tenofovir, specifically the reverse transcriptase (RT) mutation K65R, may impact the effectiveness of PrEP. The worldwide prevalence of transmitted tenofovir resistance in different HIV‐1 subtypes is unknown.MethodsSequences from treatment‐naïve studies and databases were aggregated and analyzed by Stanford Database tools and as per the International AIDS Society (IAS‐USA) resistance criteria. RT sequences were collected from GenBank, the Stanford HIV Sequence Database and the Los Alamos HIV Sequence Database. Sequences underwent rigorous quality control measures. Tenofovir‐associated resistance mutations included K65R, K70E, T69‐insertion and ≥3 thymidine analogue mutations (TAMs), inclusive of M41L or L210W.ResultsA total of 19,823 sequences were evaluated across diverse HIV‐1 subtypes (Subtype A: 1549 sequences, B: 9783, C: 3198, D: 483, F: 372, G: 594, H: 41, J: 69, K: 239, CRF01_AE: 1797 and CRF02_AG: 1698). Overall, tenofovir resistance prevalence was 0.4% (n=77/19,823, 95% confidence interval or CI: 0.3 to 0.5). K65R was found in 20 sequences (0.1%, 95% CI: 0.06 to 0.15). Differences in the prevalence of K65R between HIV‐1 subtypes were not statistically significant. K70E and ≥3 TAMs were found in 0.015% (95% CI: 0.004 to 0.04) and 0.27% (95% CI: 0.2 to 0.4) of sequences, respectively.ConclusionsPrevalence of transmitted K65R and other tenofovir resistance mutations across diverse HIV‐1 subtypes and recombinants is low, suggesting minimal effect on tenofovir‐containing PrEP regimens.
Isothermal Kinetics of Catalyzed Air Oxidation of Diesel Soot
Authors: Prasad Ram , Bella Venkateswara Rao 
Published: October 2012

To comply with the stringent emission regulations on soot, diesel vehicles manufacturers more and more commonly use diesel particulate filters (DPF). These systems need to be regenerated periodically by burning soot that has been accumulated during the loading of the DPF. Design of the DPF requires rate of soot oxidation. This paper describes the kinetics of catalytic oxidation of diesel soot with air under isothermal conditions. Kinetics data were collected in a specially designed mini-semi-batch reactor. Under the high air flow rate assuming pseudo first order reaction the activation energy of soot oxidation was found to be, Ea = 160 kJ/ mol. © 2010 by Authors, Published by BCREC Group.

A Review on Preferential Oxidation of Carbon Monoxide in Hydrogen Rich Gases
Authors: Mishra A. , Prasad Ram 
Published: October 2012

In this review, recent works on the preferential oxidation of carbon monoxide in hydrogen rich gases for fuel cell applications are summarized. H2 is used as a fuel for polymer-electrolyte membrane fuel cell (PEMFC). It is produced by reforming of natural gas or liquid fuels followed by water gas shift reaction. The produced gas consists of H2, CO, and CO2. In which CO content is around 1%, which is highly poisonous for the Pt anode of the PEMFC so that further removal of CO is needed. Catalytic preferential oxidation of CO (CO-PROX) is one of the most suitable methods of purification of H2 because of high CO conversion rate at low temperature range, which is preferable for PEMFC operating conditions. Catalysts used for COPROX are mainly noble metal based; gold based and base metal oxide catalysts among them Copper-Ceria based catalysts are the most appropriate due to its low cost, easy availability and result obtained by these catalysts are comparable with the conventional noble metal catalysts. © 2011 by Authors, Published by BCREC Group.

Authors: Ibrehem Ahmmed Saadi 
Published: October 2012

A modified model for the neutralization process of Stirred Tank Reactors (CSTR) reactor is presented in this study. The model accounts for the effect of strong acid [HCL] flowrate and strong base [NaOH] flowrate with the ionic concentrations of [Cl-] and [Na+] on the Ph of the system. In this work, the effect of important reactor parameters such as ionic concentrations and acid and base flowrates on the dynamic behavior of the CSTR is investigated and the behavior of mathematical model is compared with the reported models for the McAvoy model and Jutila model. Moreover, the results of the model are compared with the experimental data in terms of pH dynamic study. A good agreement is observed between our model prediction and the actual plant data. © 2011 by Authors, Published by BCREC Group.
