Protocolo de Treino dos Músculos do Pavimento Pélvico em Mulheres com Incontinência Urinária de Esforço: Revisão Sistemática

Introdução: Os exercícios de fortalecimento dos músculos do pavimento pélvico (EFMPP) são considerados a primeira intervenção no tratamento da incontinência urinária de esforço (IUE), porém os EFMPP são distintos, não existindo evidência sobre os parâmetros de treino. Objetivo: Identificar o protocolo e/ ou os parâmetros de treino dos músculos do pavimento pélvico (MPP) mais eficaz no tratamento da IUE feminina. Método: A pesquisa bibliográfica foi realizada entre janeiro de 1992 a março de 2014 nas bases de dados PubMed, Cochrane Library, PEDro, web of Science e LILACS. Os artigos incluídos eram de língua inglesa, estudos experimentais, no qual comparavam EFMPP com o tratamento placebo, usual ou sem tratamento, com idade compreendida entre os 18 e os 65 anos e diagnóstico de IUE. Os critérios de exclusão abrangeram o diagnóstico de IUE desencadeada por fatores externos ao trato urinário inferior, grávidas, puérperas, prolapso ≥ 2 e outros tipos de IU. A avaliação da qualidade metodológica for realizada através da escala PEDro. Resultados: Sete artigos de elevada qualidade metodológica foram incluídos na presente revisão. A amostra foi constituída por 331 mulheres, com idade média de 44,4 anos, duração média das perdas urinárias de 64 meses e a gravidade da IUE variou entre ligeira a severa. Os programas de EFMPP eram distintos em relação aos parâmetros de treino dos MPP, sendo que alguns estudos incluíram o treino abdominal, supervisão e técnicas adjuvantes. A taxa de curada da quantidade de perda urinária variou entre 28,6 a 80%, enquanto a força dos MPP variou de 15,6% a 161,7%. Conclusão: Na presente revisão sistemática, os EFMPP combinados com palpação digital, biofeedback e cones vaginais parecem ser mais eficazes na redução da quantidade de perda urinária, comparado com os EFMPP isolados ou sem tratamento. Esta revisão permitiu igualmente identificar as 12 semanas de duração da intervenção, 10 repetições por série e diferentes posições, sendo os parâmetros de treino mais consistentes na redução dos sintomas.

Defining Electricity Tariffs Using the Knowledge About the Consumers Profiles in ELECON Project

The increasing importance of the integration of distributed generation and demand response in the power systems operation and planning, namely at lower voltage levels of distribution networks and in the competitive environment of electricity markets, leads us to the concept of smart grids. In both traditional and smart grid operation, non-technical losses are a great economic concern, which can be addressed. In this context, the ELECON project addresses the use of demand response contributions to the identification of non-technical losses. The present paper proposes a methodology to be used by Virtual Power Players (VPPs), which are entities able to aggregate distributed small-size resources, aiming to define the best electricity tariffs for several, clusters of consumers. A case study based on real consumption data demonstrates the application of the proposed methodology.

Hydrogen permeation in parabolic trough receivers

The continued economic and population development puts additional pressure on the already scarce energetic sources. Thus there is a growing urge to adopt a sustainable plan able to meet the present and future energetic demands. Since the last two decades, solar trough technology has been demonstrating to be a reliable alternative to fossil fuels. Currently, the trough industry seeks, by optimizing energy conversion, to drive the cost of electricity down and therefore to place itself as main player in the next energetic age. One of the issues that lately have gained considerable relevance came from the observation of significant heat losses in a large number of receiver modules. These heat losses were attributed to slow permeation of traces of hydrogen gas through the steel tube wall into the vacuum annulus. The presence of hydrogen gas in the absorber tube results from the decomposition of heat transfer fluid due to the long-term exposure to 400°C. The permeated hydrogen acts as heat conduction mean leading to a decrease in the receivers performance and thus its lifetime. In order to prevent hydrogen accumulation, it has been common practice to incorporate hydrogen getters in the vacuum annulus of the receivers. Nevertheless these materials are not only expensive but their gas absorbing capacity can be insufficient to assure the required level of vacuum for the receivers to function. In this work the building of a permeation measurement device, vulnerabilities detected in the construction process and its overcome are described. Furthermore an experimental procedure was optimized and the obtained permeability results, of different samples were evaluated. The data was compared to measurements performed by an external entity. The reliability of the comparative data was also addressed. In the end conclusions on the permeability results for the different samples characteristics, feasibility of the measurement device are drawn and recommendations on future line of work were made.

Res Publica: Citizenship and Political Representation in Portugal, 1820-1926

The term res publica (literally “thing of the people”) was coined by the Romans to translate the Greek word politeia, which, as we know, referred to a political community organised in accordance with certain principles, amongst which the notion of the “good life” (as against exclusively private interests) was paramount. This ideal also came to be known as political virtue. To achieve it, it was necessary to combine the best of each “constitutional” type and avoid their worst aspects (tyranny, oligarchy and ochlocracy). Hence, the term acquired from the Greeks a sense of being a “mixed” and “balanced” system. Anyone that was entitled to citizenship could participate in the governance of the “public thing”. This implied the institutionalization of open debate and confrontation between interested parties as a way of achieving the consensus necessary to ensure that man the political animal, who fought with words and reason, prevailed over his “natural” counterpart. These premises lie at the heart of the project which is now being presented under the title of Res Publica: Citizenship and Political Representation in Portugal, 1820-1926. The fact that it is integrated into the centenary commemorations of the establishment of the Republic in Portugal is significant, as it was the idea of revolution – with its promise of rupture and change – that inspired it. However, it has also sought to explore events that could be considered the precursor of democratization in the history of Portugal, namely the vintista, setembrista and patuleia revolutions. It is true that the republican regime was opposed to the monarchic. However, although the thesis that monarchy would inevitably lead to tyranny had held sway for centuries, it had also been long believed that the monarchic system could be as “politically virtuous” as a republic (in the strict sense of the word) provided that power was not concentrated in the hands of a single individual. Moreover, various historical experiments had shown that republics could also degenerate into Caesarism and different kinds of despotism. Thus, when absolutism began to be overturned in continental Europe in the name of the natural rights of man and the new social pact theories, initiating the difficult process of (written) constitutionalization, the monarchic principle began to be qualified as a “monarchy hedged by republican institutions”, a situation in which not even the king was exempt from isonomy. This context justifies the time frame chosen here, as it captures the various changes and continuities that run through it. Having rejected the imperative mandate and the reinstatement of the model of corporative representation (which did not mean that, in new contexts, this might not be revived, or that the second chamber established by the Constitutional Charter of 1826 might not be given another lease of life), a new power base was convened: national sovereignty, a precept that would be shared by the monarchic constitutions of 1822 and 1838, and by the republican one of 1911. This followed the French example (manifested in the monarchic constitution of 1791 and in the Spanish constitution of 1812), as not even republicans entertained a tradition of republicanism based upon popular sovereignty. This enables us to better understand the rejection of direct democracy and universal suffrage, and also the long incapacitation (concerning voting and standing for office) of the vast body of “passive” citizens, justified by “enlightened”, property- and gender-based criteria. Although the republicans had promised in the propaganda phase to alter this situation, they ultimately failed to do so. Indeed, throughout the whole period under analysis, the realisation of the potential of national sovereignty was mediated above all by the individual citizen through his choice of representatives. However, this representation was indirect and took place at national level, in the hope that action would be motivated not by particular local interests but by the common good, as dictated by reason. This was considered the only way for the law to be virtuous, a requirement that was also manifested in the separation and balance of powers. As sovereignty was postulated as single and indivisible, so would be the nation that gave it soul and the State that embodied it. Although these characteristics were common to foreign paradigms of reference, in Portugal, the constitutionalization process also sought to nationalise the idea of Empire. Indeed, this had been the overriding purpose of the 1822 Constitution, and it persisted, even after the loss of Brazil, until decolonization. Then, the dream of a single nation stretching from the Minho to Timor finally came to an end.

El dret a l'educació i la igualtat d'oportunitats. Perspectiva històrica

La importància del sistema educatiu per a la formació d’una consciència democràtica és un tema ja present en el pensament il•lustrat i recollit en la Constitució de 1812 on es pretenia que, amb els plans d’instrucció, a partir de l’any 1830 sabessin llegir i escriure tots els ciutadans. L’objectiu d’aquesta recerca és analitzar com el dret a l’educació és determinant per al desplegament de la nostra personalitat i per a la igualtat d’oportunitats. Molts dels problemes i de les tensions presents en la configuració d’un model de sistema educatiu per a la nostra societat democràtica són conseqüència de plantejaments no resolts des de fa dos segles. La consolidació, per primer cop en la nostra història, d’un ordenament jurídic democràtic, exigeix un esforç per part de tots els agents implicats en el sistema educatiu per a possibilitar una societat on sigui vigent el principi d’igualtat d’oportunitats.

Compensation for environmental damages under international law

ABSTRACT The purpose of this research is to clarify the contribution of international dispute adjudication mechanisms in regard to environmental protection. Most specifically, the study aims to identify and develop the criterion adopted by the international judge in relation to the compensation for environmental damages. In this perspective, the study identifies some gaps between international responsibility and environmental protection interests. The premise sustained all along the study is that compensation is determinant to conciliate environmental prerogatives with mechanisms of international adjudication, in particular the system of international responsibility. Supported by the analysis of treaties, international decisions and secondary sources, the thesis defends the idea that some elements of international law allow the adjudicator to adapt the compensation to attend certain environmental interests, creating a new approach which was entitled 'fair compensation'. The antithesis of this approach is the idea that compensation in international law is limited exclusively to the strict reparation of the material losses incurred by the victim. As a synthesis, the study defends the specificity of environmental damages in relation to other kind of damages that are subject to compensation under international law. The measure upon which compensation for environmental damages could be classified as a specific type of damage under international law remains to be determined. The main conclusion of the study is that the existing standard of compensation defined by the theory and practice of international law is impossible to be strictly respected in cases involving environmental damages. This limitation is mainly due to the complexity of the notion of environment, which is constantly conflicting with the anthropologic view of legal theory. The study supports the idea that the establishment of a 'fair compensation' which takes into account the political, legal and technical context of the environmental damage, is the best possible approach to conciliate internationally responsibility and environmental interests. This could be implemented by the observance of certain elements by the international judge/arbitrator through a case-by-case analysis.

Análisis del comportamiento de los resultados en 'full' y 'direct costing'

In this paper we perform a mathematical analyse of profits and losses indirect and full costing. They are compared in different situations, mainlythe utilisation of productive capacity and the existence of beginninginventories. Direct costing was conceived as a system of cost accountingwhich would show profits as a function of sales. In full costing profitsdepend on available combinations of sales, production, costs of beginninginventories, etc., and information displayed in financial statements displayappears incongruent. Differences in profits with full and direct costingincrease when full costing allocates fixed costs according to normalproduction, in some cases differences, and financial statements would showmore incongruent performance. It is concluded about the importance thatprofit and loss statement expresses profits in both costing systems.

New methods to quantify NH3 volatilization from fertilized surface soil with urea

Gaseous N losses from soil are considerable, resulting mostly from ammonia volatilization linked to agricultural activities such as pasture fertilization. The use of simple and accessible measurement methods of such losses is fundamental in the evaluation of the N cycle in agricultural systems. The purpose of this study was to evaluate quantification methods of NH3 volatilization from fertilized surface soil with urea, with minimal influence on the volatilization processes. The greenhouse experiment was arranged in a completely randomized design with 13 treatments and five replications, with the following treatments: (1) Polyurethane foam (density 20 kg m-3) with phosphoric acid solution absorber (foam absorber), installed 1, 5, 10 and 20 cm above the soil surface; (2) Paper filter with sulfuric acid solution absorber (paper absorber, 1, 5, 10 and 20 cm above the soil surface); (3) Sulfuric acid solution absorber (1, 5 and 10 cm above the soil surface); (4) Semi-open static collector; (5) 15N balance (control). The foam absorber placed 1 cm above the soil surface estimated the real daily rate of loss and accumulated loss of NH3N and proved efficient in capturing NH3 volatized from urea-treated soil. The estimates based on acid absorbers 1, 5 and 10 cm above the soil surface and paper absorbers 1 and 5 cm above the soil surface were only realistic for accumulated N-NH3 losses. Foam absorbers can be indicated to quantify accumulated and daily rates of NH3 volatilization losses similarly to an open static chamber, making calibration equations or correction factors unnecessary.

Missouri River Floods After Action Report, December 20, 2011

In May 2011, very heavy rains combined with above average snowpack caused reservoirs throughout the Upper Missouri River basin to swell. The river carried more water in May and June than it does in an average year. The six Iowa counties bordering the river—Fremont, Harrison, Mills, Monona, Pottawattamie and Woodbury—suffered from major flooding which persisted throughout the spring and summer. On June 2, Governor Terry Branstad issued a Proclamation of Disaster Emergency for the six impacted counties. The Iowa Homeland Security and Emergency Management Division (HSEMD) activated the State Emergency Operations Center (SEOC) on June 10 to coordinate State, Federal, private sector, and voluntary agency preparedness and response activities in the affected area. The severity and duration of the flooding presented operational challenges for the SEOC and its partner agencies, which were further complicated by severe weather. The flooding forced the SEOC to conduct simultaneous response and recovery operations for an usually long period of time. The Missouri River floods caused major economic losses in Western Iowa. As a result of these economic losses, President Barack Obama issued a Major Disaster Declaration (FEMA-1998-DR) which made six counties eligible for Federal Public Assistance. The disaster declaration was subsequently amended on October 18, making five counties eligible for Federal Individual Assistance.

Portland Cement Concrete Curing Compound Performance Phase I and Phase II, MLR-02-03, 2003

Testing the efficiency of Portland Cement Concrete (PCC) curing compounds is currently done following Test Method Iowa 901-D, May 2002. Concrete test specimens are prepared from mortar materials and are wet cured 5 hours before the curing compound is applied. All brands of curing compound submitted to the Iowa Department of Transportation are laboratory tested for comparative performance under the same test conditions. These conditions are different than field PCC paving conditions. Phase I tests followed Test Method Iowa 901-D, but modified the application amounts of the curing compound. Test results showed that the application of two coats of one-half thickness each increased efficiency compared to one full thickness coat. Phase II tests also used the modified application amounts, used a concrete mix (instead of a mortar mix) and applied curing compound a few minutes after molding. Measurements of losses, during spraying of the curing compound, were noted and were found to be significant. Test results showed that application amounts, testing techniques, concrete specimen mix design and spray losses do influence the curing compound efficiency. The significance of the spray losses indicates that the conventional test method being used (Iowa 901 D) should be revised.

Erosió hídrica en vinya per a producció de vi d'alta qualitat en zona mediterrània (Anoia-Penedès): quantificació de les pèrdues de nutrients per erosió del sòl i implicacions

La vinya, malgrat que no és una planta exigent pel que fa als sòls, es veu afectada per la pèrdua de sed per causa de l'erosió hídrica. En aquest treball es presenten uns primers resultats de mesures de pèrdues de sed en condicions reals de camp. Les parcel les control són de grans dimensions, conreades segons els costums de la zona. Com a referencia es prenen les pèrdues de sòl mitjanes, calculades a partir de l'USLE, per al conreu de vinya. Es determinen, a més de les pèrdues globals de sòlids, les de nutrients que això comporta. Tenint en compte que la metodologia emprada en el camp i en el laboratori condueix a resultats per defecte, les pèrdues mesurades del període de l'any de màximes pluges (tardor) són, de mitjana, de 13 Mg ha-1 en un sistema de cultiu tradicional i fins a 100 Mg ha-1 en un sistema de cultiu emparrat. La importància del problema a curt termini encareix els factors de producció i fa perillar la sostenibilitat de la vinya a llarg termini.

Energiansäästömahdollisuudet energiayhtiön toiminnassa

Työn tarkoituksena oli etsiä energian säästökohteita Etelä-Savon Energia Oy:n voimalaitos-, kaukolämpö- sekä sähkön siirto- ja jakelualalta. Työ liittyi Etelä-Savon Energia Oy:n sopimaan valtakunnalliseen energiansäästösopimukseen, jossa yhtiö sitoutui analysoimaan energian käyttönsä ja tekemään energia-analyysin pohjalta energiansäästösuunnitelman. Tässä työssä analysoitiin nykyinen energian käyttö ja etsittiin säästökohteita. Löydetyille säästökohteille määritettiin säästön sekä tarvittavan investoinnin suuruus ja suora takaisinmaksuaika investoinnille. Voimalaitoksen osalta ei löydetty suuria säästökohteita, mutta muutamia pienempiä lähinnä lämmityksiin liittyviä kohteita havaittiin. Kaukolämmön osalta säästökohteita löytyi lähinnä lämpökeskusten seisonta-aikaisista lämmityksistä, mutta kaukolämpöverkon osalta ei kannattavia säästökohteita löydetty. Sähkön siirron ja jakelun osalta loistehon kompensoinnin lisääminen vähentäisi häviöitä verkossa ja vähentäisi kompensoinnin tarvetta voimalaitoksen generaattorilla. Isoja säästökohteita ei löydetty, koska yhtiö on vuosien varrella tehostanut toimintaansa ja pienentänyt aktiivisesti energiahäviöitä.

Kupariliekkisulatusuunin lampohavioiden maarittaminen

Työn teoriaosassa käydään läpi kuparisulaton prosessi pääpiirteittäin, jonka jälkeen siirrytään lämmönsiirron teoriaan. Lämpö siirtyy kolmella penis mekanismilla: johtumalla, säteilemällä ja konvektiolla. Naiden ilmiöiden vaikutusta kupariliekkisulatusuunin eri osissa tapahtuviin lämpöhäviöihin on käyty läpi. Lisaksi työstä löytyy kupariliekkisulatusuunin lämpö- ja ainetase sekä erilaisten lämpötilanmittauslaitteiden vertailua sekä mitä tulee ottaa huomioon lämpötiloja mitatessa. Työn kokeellisessa osassa esitellään lämpötilanmittausten perusteella lasketut kupariliekkisulatusuunin eri osien lämpöhäviöiden suuruudet mittauskampanjan ajalta. Saatuja tuloksia on vertailtu kirjallisuudesta löydettyihin aikaisempiin arvoihin. Uunin keskimääräiseksi kokonaislämpöhäviöksi saatiin 9,8 MW mittauskampanjan ajalle. Lisäksi on vertailtu uunin erilaisten ajoarvojen, kuten rikaste-, lentopöly-, murska-, ja kuonarikastesyötön suuruuden sekä öljyn syötön ja rikasteseoksen vaihtumisen vaikutusta lämpöhäviöihin sekä mietitty muita mahdollisia syitä lämpöhäviöiden vaihtelulle.
