Our understanding of how the environment can impact human health has evolved and expanded over the centuries, with concern and interest dating back to ancient times. For example, over 4000 years ago, a civilisation in northern India tried to protect the health of its citizens by constructing and positioning buildings according to strict building laws, by having bathrooms and drains, and by having paved streets with a sewerage system (Rosen 1993). In more recent times, the ‘industrial revolution’ played a dominant role in shaping the modern world, and with it the modern public health system. This era was signified by rapid progress in technology, the growth of transportation and the expansion of the market economy, which lead to the organisation of industry into a factory system. This meant that labour had to be brought to the factories and by the 1820s, poverty and social distress (including overcrowding and infrequent sewage and garbage disposal) was more widespread than ever. These circumstances, therefore, lead to the rise of the ‘sanitary revolution’ and the birth of modern public health (Rosen 1993). The sanitary revolution has also been described as constituting the beginning of the first wave of environmental concern, which continued until after World War 2 when major advances in engineering and chemistry substantially changed the face of industry, particularly the chemical sector. The second wave of environmental concern came in the mid to late 20th century and was dominated by the environmental or ecology movement. A landmark in this era was the 1962 publication of the book Silent Spring by Rachel Carson. This identified for the first time the dramatic effects on the ecosystem of the widespread use of the organochlorine pesticide, DDT. The third wave of environmental concern commenced in the 1980s and continues today. The accelerated rate of economic development, the substantial increase in the world population and the globalisation of trade have dramatically changed the production methods and demand for goods in both developed and developing countries. This has lead to the rise of ‘sustainable development’ as a key driver in environmental planning and economic development (Yassi et al 2001). The protection of health has, therefore, been a hallmark of human history and is the cornerstone of public health practice. This chapter introduces environmental health and how it is managed in Australia, including a discussion of the key generic management tools. A number of significant environmental health issues and how they are specifically managed are then discussed, and the chapter concludes by discussing sustainable development and its links with environmental health.

The Design Minds Refresh Toolkit was one of six K7-12 secondary school design toolkits commissioned by the State Library of Queensland (SLQ) Asia Pacific Design Library (APDL), to facilitate the delivery of the Stage 1 launch of its Design Minds online platform (www.designminds.org.au) partnership initiative with Queensland Government Arts Queensland and the Smithsonian Cooper-Hewitt National Design Museum, on June 29, 2012. Design Minds toolkits are practical guides, underpinned by a combination of one to three of the Design Minds model phases of ‘Inquire’, ‘Ideate’ and ‘Implement’ (supported by at each stage with structured reflection), to enhance existing school curriculum and empower students with real life design exercises, within the classroom environment. Toolkits directly identify links to Naplan, National Curriculum, C2C and Professional Standards benchmarks, as well as the student capabilities of successful and creative 21st century citizens they seek to engender through design thinking. Inspired by ideas from a design project for second year Interior Design students at QUT School of Design, this toolkit explores, through five distinct exercises, different design tools and ways to approach the future design of environments (bathrooms) to facilitate the daily washing ritual, while addressing diverse and changing social, cultural, technological and environmental challenges. The Design Minds Refresh Toolkit particularly aims to promote ‘Lateral Thinking’ attitudes and empathy as an approach to create unusual and sustainable solutions to future problems that may affect our daily behavioural routines, and the spaces that facilitate them. More generally, it aims to facilitate awareness in young people, of the role of design in society and the value of design thinking skills in generating strategies to solve basic to complex systemic challenges, as well as to inspire post-secondary pathways and idea generation for education. The toolkit encourages students and teachers to develop sketching, making, communication, presentation and collaboration skills to improve their design process, as well as explore further inquiry (background research) to enhance the ideation exercises. Exercise 1 focuses on the ‘Inquire’ and ‘Ideate’ phases, Exercise 2 and 3 build on ideation skills, and Exercise 4 and 5 concentrate on the ‘Implement’ phase. Depending on the intensity of the focus, the unit of work could be developed over a 4-5 week program (approximately 10-12 x 60 minute lessons/workshops) or as smaller workshops treated as discrete learning experiences. The toolkit is available for public download from http://designminds.org.au/refresh/ on the Design Minds website. Exercise 2 (Other People’s Shoes) and Exercise 3 (The Future Bathroom) of the toolkit were used as content for the inaugural Design Minds Professional Development Workshop on June 28, 2012 to pre-launch the website to Queensland teachers.

Photocatalytic TiO2 thin films can be highly useful in many environments and applications. They can be used as self-cleaning coatings on top of glass, tiles and steel to reduce the amount of fouling on these surfaces. Photocatalytic TiO2 surfaces have antimicrobial properties making them potentially useful in hospitals, bathrooms and many other places where microbes may cause problems. TiO2 photocatalysts can also be used to clean contaminated water and air. Photocatalytic oxidation and reduction reactions proceed on TiO2 surfaces under irradiation of UV light meaning that sunlight and even normal indoor lighting can be utilized. In order to improve the photocatalytic properties of TiO2 materials even further, various modification methods have been explored. Doping with elements such as nitrogen, sulfur and fluorine, and preparation of different kinds of composites are typical approaches that have been employed. Photocatalytic TiO2 nanotubes and other nanostructures are gaining interest as well. Atomic Layer Deposition (ALD) is a chemical gas phase thin film deposition method with strong roots in Finland. This unique modification of the common Chemical Vapor Deposition (CVD) method is based on alternate supply of precursor vapors to the substrate which forces the film growth reactions to proceed only on the surface in a highly controlled manner. ALD gives easy and accurate film thickness control, excellent large area uniformity and unparalleled conformality on complex shaped substrates. These characteristics have recently led to several breakthroughs in microelectronics, nanotechnology and many other areas. In this work, the utilization of ALD to prepare photocatalytic TiO2 thin films was studied in detail. Undoped as well as nitrogen, sulfur and fluorine doped TiO2 thin films were prepared and thoroughly characterized. ALD prepared undoped TiO2 films were shown to exhibit good photocatalytic activities. Of the studied dopants, sulfur and fluorine were identified as much better choices than nitrogen. Nanostructured TiO2 photocatalysts were prepared through template directed deposition on various complex shaped substrates by exploiting the good qualities of ALD. A clear enhancement in the photocatalytic activity was achieved with these nanostructures. Several new ALD processes were also developed in this work. TiO2 processes based on two new titanium precursors, Ti(OMe)4 and TiF4, were shown to exhibit saturative ALD-type of growth when water was used as the other precursor. In addition, TiS2 thin films were prepared for the first time by ALD using TiCl4 and H2S as precursors. Ti1-xNbxOy and Ti1-xTaxOy transparent conducting oxide films were prepared successfully by ALD and post-deposition annealing. Highly unusual, explosive crystallization behaviour occurred in these mixed oxides which resulted in anatase crystals with lateral dimensions over 1000 times the film thickness.

Somente poderiam advir novas formas de existência, outros modos de ser e estar no mundo, se diferentes sensibilidades também acompanhassem o desdobrar de um determinado acontecimento. Esta pesquisa tem como objeto privilegiado os acontecimentos de criação da escola na sua relação com as visibilidades de mundo, fazendo-se ela mesma em preparação e ressurgência de um acontecimento de criação. Inicialmente seria fundamental à pesquisa envolver-se nos cotidianos do colégio estudado para melhor pensar a via de preparação do acontecimento. Tal feita somente poderia adquirir sentido se o dispositivo investigativo mantivesse seus investimentos ao nível do contato com estudantes, esforçando-se por garantir a maior participação deles em diferentes aspectos da preparação, acentuando a partir de nossos encontros à potência de criação evenemencial. Ceder aos indícios durante a preparação significaria aprofundar os vínculos que mantive com a comunidade escolar. E, tendo como principal convite a fotografia, os estudantes realizaram um número significativo de imagens do colégio que, ao final de um extenso período, nos conduziu à ocupação imagética do espaço escolar. Num segundo momento a pesquisa se voltou para o modo de apreensão do acontecimento por parte de toda a comunidade em meio à ocupação do espaço escolar a partir de suas imagens. Composta por oitenta e uma fotografias do espaço escolar, a ocupação concentrou parte destas imagens em uma instalação confeccionada por fios vermelhos no centro do primeiro pavimento, distribuindo o restante delas por entre paredes, banheiros e corredores. Esta apreensão se fez compreendida pelo dispositivo sob os termos de um profundo engajamento com o campo problemático do acontecimento, tendo como índice o destino investido pelas imagens, prolongando senão os efeitos evenemenciais em franca atualização dos gestos, superfícies e visibilidades. Procurei pensar a multiplicidade de relações estabelecidas entre a comunidade escolar e as imagens fotográficas em meio à ocupação imagética realizada no colégio, tomando a sua aparição momentânea como acontecimento de criação, assim como a ressurgência de outras visibilidades presididas em seus contextos. Para tanto, pesquisa precisou se tornar esta íntima criação de uma obra de aprendizagem.

Värmedrivna vitvaror eller HWC-maskiner som de kallas av tillverkaren värms med varmt vatten från en cirkulerande krets via en värmeväxlare inbyggd i maskinen, till skillnad från konventionella maskiner som värms med el. Denna teknik skall inte förväxlas med maskiner som är anslutna till varmvattenledningen och fylls på med varmt vatten och som därmed begränsas till disk- och tvätt. Syftet med fjärrvärmedrivna vitvaror är alltså att använda fjärrvärme, som har lägre kvalitet och pris än elenergi för uppvärmning och torkning och på så sätt spara el och utöka fjärrvärmeunderlaget. En jämförelse av koldioxidutsläpp och primärenergianvändning mellan konventionella vitvaror och fjärrvärmedrivna vitvaror visar att både koldioxidutsläpp och primärenergianvändning blir lägre för fjärrvärmedrivna vitvaror om biobränsle anses koldioxidneutralt och den el som ersätts är producerad i kolkraftverk eller gaskombikraftverk. Denna rapport beskriver utveckling och kommersialisering av värmedrivna vitvaror (disk- och tvättmaskiner samt torktumlare och torkskåp) och hur de kan anslutas mot fjärrvärmesystem i olika systemlösningar. Dessutom har de energimässiga och ekonomiska förutsättningarna för tekniken undersökts. Erfarenheterna från fältprovning är dock mycket begränsade, eftersom de byggen där fälttesterna skulle ske försenades. Under 2013 färdigställs ett flerbostadshus med värmedrivna vitvaror i 160 lägenheter i Västerås. De utvecklade maskinernas värmeanvändning som andel av total energianvändning vid 60 graders framledningstemperatur har uppmätts till ca 50 % för diskmaskinen, 67 % för tvättmaskinen, 80 % för torktumlaren och 93 % för torkskåpet. I det studerade flerbostadshuset av passivhusstandard uppgår lasten från värmedrivna vitvaror komfortgolvvärme och handdukstorkar till upp mot 30 % av husets totala värmeanvändning. För småhus är motsvarande siffra upp mot 20 %. Att använda fjärrvärme istället för elvärme till dessa installationer som normalt är elvärmda kan allts minska elbehovet betydligt i lågenergibebyggelse vilket också minskar både koldioxidutsläppen och primärenergianvändningen. Ekonomiska analyser har genomförts för två olika systemkoncept (separat vitvarukrets och Västeråsmodellen) för nybyggda småhusområden och flerfamiljshus där fjärrvärme inte bara används till vitvaror utan också till handdukstorkar och komfortgolvvärme. De ekonomiska analyserna visar att Västeråsmodellen är den mest ekonomiskt intressanta systemlösningen med värmedrivna vitvaror, handdukstork och komfortgolvvärme. I flerfamiljshus kan den vara konkurrenskraftig mot de elvärmda alternativen (konventionellt system med eldrivna vitvaror, komfortgolvvärme och handdukstorkar) om prisskillnaden mellan el och fjärrvärme är större än 0,7 kr/kWh. En parameterstudie visar att kapitalkostnaden blir ganska hög jämfört med energikostnaden, vilket betyder att lång livslängd och många cykler är viktigt för att förbättra de ekonomiska förutsättningarna för värmedrivna vitvaror. För passiva småhus blir kostnaden för Västeråsmodellen med värmedrivna vitvaror, handdukstork och komfortgolvvärme likvärdig med de elvärmda alternativen vid energiprisskillnader på 0,7 kr/kWh inklusive moms, medan det krävs prisskillnader på 0,9 kr/kWh inklusive moms för normalisolerade småhusområden. Sammanfattningsvis kan sägas att i kommuner med ett konkurrenskraftigt fjärrvärmepris finns det viss lönsamhet för hela konceptet enligt Västeråsmodellen med värmedrivna vitvaror, komfortgolvvärme, och handdukstorkar. Om man däremot ser på konkurrensen för enskilda vitvaror är det främst torktumlaren som är konkurrenskraftig i bostäder. Målpriset på 1000 kr extra för värmedrift har inte kunnat uppnås inom projektet för diskmaskiner och tvättmaskiner. Det krävs lägre priser och låga anslutningskostnader för att räkna hem diskmaskinen och tvättmaskinen som enskilda komponenter. Värmedrivna tvättmaskiner och torktumlare är konkurrenskraftiga i flerfamiljstvättstugor. Speciellt i de fall där beläggningen är god och flera maskiner delar på anslutningskostnaden till fjärrvärmecentralen kan värmedrift bli riktigt lönsam. Torkskåpens konkurrenskraft har inte kunnat utvärderas, då priset ännu inte fastställts. Att använda VVC-systemet för värmedistribution till värmedrivna vitvaror kan vara mycket intressant, men det kräver att legionellaproblematiken kan lösas. I nuläget finns ingen lösning som uppfyller formuleringarna i boverkets byggregler. Ett annat distributionssätt som kan vara intressant, men som inte undersökts i studien är att använda VVC för varmvattendistribution och en gemensam radiator- och vitvarukrets med konstant framledningstemperatur. Den aktör som förväntas ha störst ekonomiskt intresse av att tekniken implementeras är sannolikt fjärrvärmebolagen som får sälja mer värme och det ligger därmed främst på deras ansvar att marknadsföra tekniken i mötet med sina kunder.

This dissertation tries to describe the interactions called pegações in the homosexual milieu that exist in the public bathrooms in UFRN. They used for sexual practices by some of their users. The participating observation made it possible a discription concerning how the interactions occur among the bathrooms users. We researched the flert process that happens around the place, the poses they strike, the approach, until they get to the sexual practice. We also traced their route through the most used bathrooms. We associated the research the messages written on the doors and cabins that are means of contact among the users. So we tried to interpret the meanings of the interactions that exist in the public bathrooms in UFRN

Only 32% of the population of Natal is attended by sewage, while the remaining population use pits and septic tanks. The characterization of the contents of septic tanks and pits contributes to the performance of such system and may guide the decision on treatment of these contents. The main of this research is to characterize the contents of interior residential pits and septic tanks in the greater Natal, with the following specific goals: to develop and manufacture a sampler capable of collecting a representative sample of the entire column (the surface scum, the clarified liquid and sludge bottom); to compare the contents of the tanks with the pits; to compare the contents of the septage from vacuum trucks; to relate the composition content with socioeconomic characteristics of households; to compare the content in both chambers of the septic tanks in series; to assess the situation of the content before and six months after the cleanness; and ultimately propose a pilot scale plant for treatment of septage. Once the sampler was developed, samples were collected within 14 septic tanks and 10 pits in many districts of Natal. Medians of the 24 systems were obtained: temperature, pH, conductivity, oil and grease, total solids, total suspended solids and sediments of 28.0 °C, 6.95; 882 mS/cm, 75.2 mg/L; 10,169 mg/L, 6,509 mg/L and 175 mL/L respectively; 111.0 mgN/L for ammonia, 130.5 mgN/ L for organic nitrogen, 0.2 mgN/L for nitrite, 0.4 mg/L for nitrate; 8935 mgO2/L for COD, 29.2 mgP/L for total phosphorus, thermotolerant coliforms from 9.95 E +06 CFU/100mL helminth eggs and 9.2 eggs/L with a maximum concentration of 688 eggs/L and minimum of 0 eggs/L. Medians of organic nitrogen and TKN were significantly different between groups of tanks and pits. The systems with cleanness gap from 11 and 20 years presented the higher concentrations for most variables. The effluent from the toilets and bathrooms participate more effectively in contributing fractions of solids, alkalinity, nitrogen, COD, total phosphorus, thermotolerant coliforms and helminth eggs. The systems used by socioeconomics class with income from R$ 3,700.00 to R$ 7,600.00, presented higher concentrations for COD, nitrogen, solids and helminth eggs. The first of the two chambers had always presented higher concentrations over the second compartment. The analysis of variance for most variables, showed that the values of septic tanks, pits and septage from vacuum trucks belong to the same group. In the samples taken after cleanness, the median of pH and temperature increased, while alkalinity, COD, organic nitrogen, total phosphorus, ammonia and helminth eggs decreased. The oils and greases and thermotolerant coliforms had slightly varied due to the continuous release of sewage into the systems that maintained their steady state concentrations.

Esta pesquisa apresenta o estudo comparativo de reatores anaeróbio de fluxo ascendente e manta de lodo (UASB) e tanque séptico (TS), a fim de investigar a utilização destes reatores em escala unifamiliar no tratamento de esgotos domiciliares. A pesquisa foi realizada em comunidade quilombola próxima a cidade de Belém- PA. Para isto, foram utilizados oito reatores UASB (em forma de “Y”.) e um tanque séptico prismático de câmara única. Os reatores UASB possuíam volume de 0,42 m3, enquanto que o tanque séptico volume de 4,20 m3. Cada reator foi instalado em um domicilio, sendo alimentados exclusivamente por esgoto negro (água, fezes e urina) oriundo dos vasos sanitários dos banheiros. Foi analisada a viabilidade técnica da utilização do primeiro em substituição ao segundo, tendo em vista que o TS é amplamente utilizado em locais do Brasil desprovidos de redes coletoras de esgoto. As operações foram realizadas simultaneamente durante aproximadamente 90 semanas, sendo monitorados parâmetros que possibilitaram a análise da estabilidade operacional e do desempenho de cada reator. Ao final da pesquisa foi observado que os reatores UASB apresentaram desempenho tão satisfatório ou melhor que o do TS no tratamento da matéria orgânica e de sólidos em suspensão. Com isso, ficou evidenciada a viabilidade da aplicação do reator UASB utilizado no tratamento unifamiliar de esgotos de pequenas comunidades rurais.

As an undergraduate sociology major, the only thing I learned about Oklahoman Laud Humphreys's classic, Tearoom Trade (1970) was how it violated standards of informed consent in social science research. As Galliher, Brekhus, and Keys recount in their biography, Laud Humphreys: Prophet of Homosexuality and Sociology, sociology graduate student Laud Humphreys needed to supplement his (quite likely, participant) observational research of men who had sex in public bathrooms (i.e., tearooms) in St. Louis in the mid-1960s with a formal questionnaire. Knowing that these men would never agree if they knew they were selected because of their participation in highly stigmatized and criminal behavior, Humphreys recorded their license plates, got their home addresses, and interviewed them as part of a "community health survey." Herein lies the deception and the major source of the controversy. What I didn't fully appreciate when I was a student, however, and what the authors so deftly illuminate is the importance of this work not only for debates around ethical issues of social science research, but more importantly, perhaps, for the study of sexuality, deviance, and urban life.

The transfer coefficient of radon from water to air was investigated in schools. Kitchens, bathrooms and locker rooms were studied for seven schools in Maine. Simulations were done in water-use rooms where radon in air detectors were in place. Quantities measured were radon in water (270-24500 F) and air (0-80 q), volume of water used, emissivities (0.01-0.99) and ventilation rates (0.012-0.066A). Variation throughout the room of the radon concentration was found. Values calculated for the transfer coefficient for kitchens and baths were ranged from 9.6 x to 2.0 x The transfer coefficient was calculated using these parameters and was also measured using concentrations of radon in water and air. This provides a means by which radon in air can be estimated using the transfer coefficient and the concentration in the water in other schools and it can be used to estimate the dose caused by radon released from water use. This project was partially funded by the United States Environmental Protection Agency (grant #X828l2 101-0) and by the State of Maine (grant #10A500178). These are the first measurements of this type to be done in schools in the United States.

A maioria das demandas envolvendo pedidos de danos morais no judiciário trabalhista brasileiro é originada a partir de abusos patronais cometidos no exercício do poder diretivo, em especial de sua dimensão fiscalizatória. Embora inexista, no Brasil, disciplina normativa específica quanto aos limites à maior parte das manifestações do poder de fiscalização, seu exercício é restringido pela dignidade da pessoa humana, que deve ser compreendida de acordo com a noção de trabalho decente propugnada pela OIT. A dignidade humana constitui cláusula geral de proteção aos direitos da personalidade, dentre eles, os direitos à intimidade e à vida privada, os mais ofendidos por meio da fiscalização patronal abusiva nas fases précontratual, contratual e pós-contratual. Práticas como a revista pessoal nos trabalhadores e em seus pertences, a limitação à utilização de banheiros, a instalação de câmeras e microfones no local de trabalho e o monitoramento dos computadores utilizados na empresa revelam, por vezes, violações a esses direitos. A revista não encontra fundamento no poder de fiscalização e no direito de propriedade do empregador, salvo quando tiver por objetivo a garantia da saúde ou segurança no ambiente laboral. A instalação de equipamentos audiovisuais, quando visar a proteção patrimonial do empregador ou for essencial ao procedimento de gestão, somente pode se dar nos espaços em que o trabalho for efetivamente desenvolvido e por tempo determinado, fundada em situação específica, sendo imprescindível a ciência dos monitorados quanto à instalação e à localização dos equipamentos. A escuta telefônica e o monitoramento de computadores e e-mails somente será possível quando o empregador determinar a utilização dos meios exclusivamente para os fins da prestação laboral, com ciência inequívoca dos trabalhadores, além de disponibilizar ou autorizar a utilização de meios alternativos para a comunicação pessoal. Não devem ser admitidas quaisquer limitações à utilização de banheiros, bem como o estabelecimento de escala de gravidez no âmbito empresarial. Sendo o tomador de serviços legitimado a exercer o poder fiscalizatório sobre a atividade produtiva empreendida no estabelecimento e havendo a indiscutível imperatividade da proteção aos direitos da personalidade obreiros, é necessária a fixação normativa de limites ao poder patronal, em prol do estabelecimento da segurança jurídica. O direito de resistência é contraface do poder diretivo, no sentido de que o uso irregular deste faz nascer aquele e, consequentemente, os limites do poder diretivo condicionam os do ius resistentiae. Os trabalhadores devem exercê-lo com fulcro nos direitos à vida privada, à intimidade, à honra e à dignidade humana. A doutrina deve valer-se da técnica da ponderação para estabelecer os limites ao poder fiscalizatório patronal, com fulcro no princípio da proporcionalidade. A divergência jurisprudencial deve ser minimizada pela atividade criativa dos juízes quanto aos limites ao poder fiscalizatório, consoante o princípio da proporcionalidade, e por meio da utilização de mecanismos específicos voltados à redução da insegurança jurídica no Judiciário Trabalhista, tais como recursos de revista, embargos de divergência, incidentes de uniformização de jurisprudência, súmulas, precedentes normativos e orientações jurisprudenciais. Nada impede, ainda, que limites ao poder fiscalizatório patronal sejam estabelecidos por meio de negociação coletiva.

El objetivo de este trabajo es el análisis de los espacios públicos donde la oligarquía alicantina interactúa en su tiempo libre. A este respecto, encontramos referencias donde se describen los paseos por las alamedas de la ciudad, las tertulias en los cafés y la asistencia tanto a los teatros como a los toros; junto a la concurrencia a los baños públicos y a las celebraciones religiosas y profanas. Por último, destaca una actividad: los desplazamientos fuera del domicilio habitual. Estos tienen una motivación extraeconómica que obedece a la búsqueda de unas condiciones climáticas favorables y de relación social en las diferentes villas de la huerta alicantina. Ello sugiere que la vida social de la capital se traslada a la mencionada huerta donde se organizarían tertulias, recepciones, fiestas así como algún espectáculo musical y teatral.
