Swimming lessons : learning, new materialisms, posthumanism, and post qualitative research emerge through a pool poem

This article shifts from the formal learning spaces of school anduniversity to an Australian public swimming pool to playfullyengage some of the dilemmas that recent theory poses forcurriculum studies. The article enacts multiple diffractions(Barad, 2007) as theory becomes swimming and swimmingbecomes theory, and ideas and movements are themselvesdiffracted or changed by the writing of a poem. What does thepool teach us? What is learnt at the pool? How does learningemerge at the pool? Physics, chemistry, biology, and artistrycombine, as multiple human and non-human bodies intra-act(Barad, 2007), calling each other into being in this exploration ofhow distributed agencies and fractal causalities (Bennett, 2010)change how learning might be thought, represented, andswum. The poem incorporated here serves as provocation andinspiration for other scholars struggling with these educationaldilemmas and interested in arts-based research.

New sale and leasing requirements for owners of swimming pools and their application to strata schemes

This article considers the changes to the Swimming Pools Act 1992 (NSW)(Act) which established a State-wide online register of all private swimming pools in NSW requiring pool owners to register their pools by 19 November 2013. Amendments to the Act introduced changes to the conveyancing and residential tenancy regulations to require vendors and landlords to have a valid Compliance Certificate issued for their swimming pool before offering the property for sale or lease. This article provides a brief overview of the new sale and leasing requirements effective from 29 April 2014, focusing on its application to lot owners within strata and community title schemes and other owners of water front properties with pools on Crown Land Reserves.

The deep end: pedagogy and the public pool

Diving in to New Materialist theory, this paper explores what might be learnt at a public swimming pool. Writing, sitting, thinking and swimming, the learner enters new spaces and atmospheres, where learning emerges as unpredictable and involving a whole range of human and non human bodies. Public spaces, where we can think about causality and design without the strictures of school curriculum, may emerge as key sites for new understandings of learning where abiding humanist preoccupations can slip away. This presentation involves movement, touching, flesh, smelling, silicone, cotton and water. Be prepared to get changed!

Caregiver factors and pool fencing: An exploratory analysis

To explore the relationship between caregiver characteristics and the adequacy of domestic swimming pool fencing.A typical metropolitan area of a large Australian capital city, Brisbane.From a reanalysis of the dataset of the 1989 Brisbane Home Safety Survey of 1050 householders, associations between 10 caregiver factors, pool ownership, and quality of pool fencing, were analysed. Household characteristics relating to toddlers (children < or = 4 years), and socioeconomic measures were also included in the analyses. Pool fencing quality was measured on an ordinal scale derived from Australian Standards Association guidelines, confirmed through home visits by trained inspectors.Caregiver factors did not distinguish households with a swimming pool from those without, nor were they associated with adequacy of pool fencing among pool owners. Pool owners, with or without children, were less likely to perceive having a childproof fence as being important. Strongest correlates of adequacy of pool fencing were socioeconomic indicators of surrounding districts.These results do not support the arguments of opponents of compulsory pool fencing that caregiver factors are adequate to prevent toddler drownings and obviate the need for a pool fence. Pool owners do not appear to perceive their pool as a hazard for young children, and complacency about the adequacy of pool fencing needs to be replaced by increased caregiver health beliefs, skills, and perceptions.

Near-infrared spectroscopic studies of human scalp hair in a forensic context

Human hair is a relatively inert biopolymer and can survive through natural disasters. It is also found as trace evidence at crime scenes. Previous studies by FTIRMicrospectroscopy and – Attenuated Total Reflectance (ATR) successfully showed that hairs can be matched and discriminated on the basis of gender, race and hair treatment, when interpreted by chemometrics. However, these spectroscopic techniques are difficult to operate at- or on-field. On the other hand, some near infrared spectroscopic (NIRS) instruments equipped with an optical probe, are portable and thus, facilitate the on- or at –field measurements for potential application directly at a crime or disaster scene. This thesis is focused on bulk hair samples, which are free of their roots, and thus, independent of potential DNA contribution for identification. It explores the building of a profile of an individual with the use of the NIRS technique on the basis of information on gender, race and treated hair, i.e. variables which can match and discriminate individuals. The complex spectra collected may be compared and interpreted with the use of chemometrics. These methods can then be used as protocol for further investigations. Water is a common substance present at forensic scenes e.g. at home in a bath, in the swimming pool; it is also common outdoors in the sea, river, dam, puddles and especially during DVI incidents at the seashore after a tsunami. For this reason, the matching and discrimination of bulk hair samples after the water immersion treatment was also explored. Through this research, it was found that Near Infrared Spectroscopy, with the use of an optical probe, has successfully matched and discriminated bulk hair samples to build a profile for the possible application to a crime or disaster scene. Through the interpretation of Chemometrics, such characteristics included Gender and Race. A novel approach was to measure the spectra not only in the usual NIR range (4000 – 7500 cm-1) but also in the Visible NIR (7500 – 12800 cm-1). This proved to be particularly useful in exploring the discrimination of differently coloured hair, e.g. naturally coloured, bleached or dyed. The NIR region is sensitive to molecular vibrations of the hair fibre structure as well as that of the dyes and damage from bleaching. But the Visible NIR region preferentially responds to the natural colourants, the melanin, which involves electronic transitions. This approach was shown to provide improved discrimination between dyed and untreated hair. This thesis is an extensive study of the application of NIRS with the aid of chemometrics, for matching and discrimination of bulk human scalp hair. The work not only indicates the strong potential of this technique in this field but also breaks new ground with the exploration of the use of the NIR and Visible NIR ranges for spectral sampling. It also develops methods for measuring spectra from hair which has been immersed in different water media (sea, river and dam)

Esprit Futur : Le Corbusier and José Oubrerie at Saint-Pierre De Firminy, Firminy-Vert, France, 1968–2006

What is the secret mesmerism that death possesses and under the operation of which a modern architect – strident, confident, resolute – becomes rueful, pessimistic, or melancholic?1 Five years before Le Corbusier’s death at sea in 1965, the architect reluctantly agreed to adopt the project for L’Église Saint-Pierre de Firminy in Firminy-Vert (1960–2006), following the death of its original architect, André Sive, from leukemia in 1958.2 Le Corbusier had already developed, in 1956, the plan for an enclave in the new “green” Firminy town, which included his youth and culture center and a stadium and swimming pool; the church and a “boîte à miracles” near the youth center were inserted into the plan in the ’60s. (Le Corbusier was also invited, in 1962, to produce another plan for three Unités d’Habitation outside Firminy-Vert.) The Saint-Pierre church should have been the zenith of the quartet (the largest urban concentration of works by Le Corbusier in Europe, and what the architect Henri Ciriani termed Le Corbusier’s “acropolis”3) but in the early course of the project, Le Corbusier would suffer the diocese’s serial objections to his vision for the church – not unlike the difficulties he experienced with Notre Dame du Haut at Ronchamp (1950–1954) and the resistance to his proposed monastery of Sainte-Marie de la Tourette (1957–1960). In 1964, the bishop of Saint-Étienne requested that Le Corbusier relocate the church to a new site, but Le Corbusier refused and the diocese subsequently withdrew from the project. (With neither the approval, funds, nor the participation of the bishop, by then the cardinal archbishop of Lyon, the first stone of the church was finally laid on the site in 1970.) Le Corbusier’s ambivalence toward the project, even prior to his quarrels with the bishop, reveals...

Mycobacterium abscessus infection and potable water

Mycobacterium abscessus is a rapidly growing mycobacteria responsible for progressive pulmonary disease, soft tissue and wound infections, and can contaminate clinical specimens. Nontuberculous mycobacteria (NTM) are generally considered environmental organisms though M. abscessus has not featured frequently in environmental studies, particularly those examining potable water. In a study of Brisbane potable water, M. abscessus was isolate from ten different locations. The incidence of disease due to M. abscessus has been increasing in Queensland. Aim: To compare genotypically the M. abscessus isolates obtained from water to those obtained from human clinical specimens. Methods: From a study of Brisbane potable water between 2007 and 2009, ten isolates confirmed as M. abscessus were recovered. In addition, one strain was isolated from a rainwater tank of a patient with disease due to M. avium, and another from the swimming pool of a patient with M. intracellulare disease. A random sample of 74 clinical isolates referred to the QLD Mycobacterial reference laboratory during the same time period was available for comparison using repPCR strain typing (Diversilab). Results: The drinking water isolates formed two distinct strain patterns (A and B) that shared >90% similarity. The tankwater isolate (pattern C) shared >85% similarity with the potable water isolates, but the pool isolate (D) was distinctly different. Fifty-three clinical isolates clustered tightly (>95% similarity) with the Group A potable water isolates, 4 patients with Group B. Thirteen patient isolates clustered with the Rainwater tank isolate. One patient matched the pool isolate. There were a further 3 patient isolates that were unrelated to the water isolates. No differences were found between strain types in terms of geographic origin, gender, age, or site/type of infection. Conclusion: The high degree of similarity between strains of M. abscessus from potable water and strains causing infection in humans from the same area, strengthens the possibility that drinking water may be a source of infection in these patients.

Mycobacterium abscessus isolated from municipal water : a potential source of human infection

Background Mycobacterium abscessus is a rapidly growing mycobacterium responsible for progressive pulmonary disease, soft tissue and wound infections. The incidence of disease due to M. abscessus has been increasing in Queensland. In a study of Brisbane drinking water, M. abscessus was isolated from ten different locations. The aim of this study was to compare genotypically the M. abscessus isolates obtained from water to those obtained from human clinical specimens. Methods Between 2007 and 2009, eleven isolates confirmed as M. abscessus were recovered from potable water, one strain was isolated from a rainwater tank and another from a swimming pool and two from domestic taps. Seventy-four clinical isolates referred during the same time period were available for comparison using rep-PCR strain typing (Diversilab). Results The drinking water isolates formed two clusters with ≥97% genetic similarity (Water patterns 1 and 2). The tankwater isolate (WP4), one municipal water isolate (WP3) and the pool isolate (WP5) were distinctly different. Patient isolates formed clusters with all of the water isolates except for WP3. Further patient isolates were unrelated to the water isolates. Conclusion The high degree of similarity between strains of M. abscessus from potable water and strains causing infection in humans from the same geographical area, strengthens the possibility that drinking water may be the source of infection in these patients.

DOŚWIADCZENIE PRZESTRZENI W PAMIĘCI O HOLOCAUŚCIE

This paper analyzes different experiences of space by which memory of Holocaust could be passed on. The Memorial for the murdered Jews of Europe in Berlin gives visitors the feeling of insecurity and overwhelms them with monumentality. For that reason it is criticized as reflecting the other side of German memory: The Third Reich’s megalomania and dream about power. The Hamburger memorial against fascism designed in 1986 by conceptual artists Jochen and Esther Gerz offers quite an opposite experience of space. A twelve-meter-high pillar has been established for visitors to sign on it. Once the area was covered by signature it was lowered into the ground till it completely disappeared. The intention of the artists was to put memory not into the monument but into people. Pozdrowienia z Alej Jerozolimskich (Greetings from the Jerusalem Avenue, 2002) by Joanna Rajkowska – a fifteen-meter tall artificial palm tree installed in the centre of Warsaw – is an attempt to infuse with Israel's scenery a Warsaw's street whose name and history sends the observer to the history of the Jews in Poland. In another work called Dotleniacz (Oxygenator, 2007) Rajkowska created an artificial lake with oxygen concentrators, gold fish, flowers and banks. Again, the installation was placed in a very meaningful place – Grzybowski Square – which is strongly connected with Jewish life in Poland as well as Polish anti-Semitism. The synagogue in Poznan was transformed during the Nazi occupation into a swimming pool which it has remained until the present day. This fact ( just like the building) seems to be invisible for most citizens. In 2003 Rafał Jakubowicz changed the fact by projecting a Hebrew inscription הייחש-תכירב (swimming pool) on the façade of the former synagogue. In Berek (The Game of Tag, 1999) by Artur Żmijewski a group of naked men and women of various age play tag. The artist filmed them in two rooms: in a symbolically neutral space and in a gas chamber of a former Nazi death camp. The film is an attempt at breaking the spell of this horrifying and paralysing space.

Avaliação do desempenho energético e da qualidade do ar de uma piscina coberta

Este trabalho teve como propósito fazer uma avaliação do desempenho energético e da qualidade do ar no interior das instalações de uma Piscina Municipal Coberta, localizada na zona norte de Portugal, sendo estabelecidos os seguintes objetivos: caracterização geral da piscina, no que respeita aos seus diferentes espaços e equipamentos, cálculo dos consumos térmicos e elétricos bem como o registo das concentrações de elementos poluentes para controlo da qualidade do ar no interior da piscina, tendo como base a legislação atualmente em vigor. A caracterização geral da piscina permitiu verificar algumas inconformidades como a temperatura da água nos tanques de natação que tem valores superiores aos recomendados e a sala de primeiros socorros que não possui acesso direto ao exterior. Acrescente-se que o pavimento nos chuveiros da casa de banho feminina e os valores de pH para água do tanque grande e pequeno não estão sempre dentro da gama de recomendação. O caudal da renovação de ar está a ser operado manualmente e quando está a funcionar a 50% da sua capacidade máxima, que acontece numa parte do dia, apenas consegue renovar 77,5% do caudal recomendado pelo RSECE. Para se obter o valor recomendado é necessário ter pelo menos 7 horas com o caudal a 100% da capacidade máxima. A avaria na UTA2 originou que 40% dos registos diários da humidade relativa interior estivessem fora da gama de valores recomendados e que esta é fortemente dependente da humidade no exterior e pode ser agravada quando as portas dos envidraçados da nave são abertas. Analisando ainda a quantidade de água removida na desumidificação do ar com a água evaporada em condições de Outono-Inverno ou Primavera-Verão, este estudo permitiu concluir que todas as combinações demonstraram a necessidade de desumidificação salvo a combinação Outono-Inverno e UTA2 a funcionar a 100% da sua capacidade máxima. Os isolamentos das tubagens na sala das caldeiras foram observados e comparados com as soluções recomendadas pelas empresas especialistas e verificou-se que alguns estão mal colocados com parcial ou total degradação, promovendo perdas térmicas. No caso das perdas calorificas por evaporação, estas representaram cerca de 67,78% das perdas totais. Como tal, estudou-se a aplicação de uma cobertura sobre o plano de água durante o período de inatividade da piscina (8 horas) e verificou-se que o resultado seria uma poupança de 654,8 kWh/dia, na ausência de evaporação da água, mais 88,00 kWh/dia do período da UTA2 a funcionar a 50% da sua capacidade, perfazendo um total de 742,8 kWh/dia. A aplicação da cobertura permite obter um VAL de valor positivo, uma TIR de 22,77% e sendo este valor superior ao WACC (Weight Average Cost of Capital), o projeto torna-se viável com um Pay-Back de 3,17 anos. Caracterizou-se também o consumo total diário em eletricidade, e verificou-se que as unidades de climatização, as bombas de circulação de água, a iluminação, e outros equipamentos representam, respetivamente, cerca de 67,81, 25,26, 2,68 e 3,91% da energia elétrica total consumida. Por fim, a análise à qualidade do ar no interior da nave em Maio e Setembro identificou que as concentrações de ozono apresentavam valores no limite do aceitável em Maio e superiores ao valor de emissão em Setembro. Os compostos orgânicos voláteis também apresentavam valores em Maio 4,98 vezes superior e em Setembro 6,87 vezes superior aos valores máximos exigidos pelo D.L. nº 79/2006. Houve ainda altas concentrações de radão registadas na casa dos filtros, em Maio com um valor 11,49 vezes superior, no entanto esse valor desceu em Setembro para 1,08 vezes, mesmo assim superior ao exigido pelo D.L. nº 79/2006.

Estudo da Viabilidade Técnico-Económica de umm Sistema de Cogeração para um Complexo de Piscinas Interiores

A presente dissertação centrou-se no estudo técnico-económico de dois cenários futuros para a continuação de fornecimento de energia térmica a um complexo de piscinas existente na região do vale do Tâmega. Neste momento a central de cogeração existente excedeu a sua licença de utilização e necessita de ser substituída. Os dois cenários em estudo são a compra de uma nova caldeira, a gás natural, para suprir as necessidades térmicas da caldeira existente a fuelóleo, ou o uso de um sistema de cogeração compacto que poderá estar disponível numa empresa do grupo. No primeiro cenário o investimento envolvido é cerca de 456 640 € sem proveitos de outra ordem para além dos requisitos térmicos, mas no segundo cenário os resultados são bem diferentes, mesmo que tenha de ser realizado o investimento de 1 000 000 € na instalação. Para este cenário foi efetuado um levantamento da legislação nacional no que toca à cogeração, recolheram-se dados do edifício como: horas de funcionamento, número de utentes, consumos de energia elétrica, térmica, água, temperatura da água das piscinas, temperatura do ar da nave, assim como as principais características da instalação de cogeração compacta. Com esta informação realizou-se o balanço de massa e energia e criou-se um modelo da nova instalação em software de modelação processual (Aspen Plus® da AspenTech). Os rendimentos térmico e elétrico obtidos da nova central de cogeração compacta foram, respetivamente, de 38,1% e 39,8%, com uma percentagem de perdas de 12,5% o que determinou um rendimento global de 78%. A avaliação da poupança de energia primária para esta instalação de cogeração compacta foi de 19,6 % o que permitiu concluir que é de elevada eficiência. O modelo criado permitiu compreender as necessidades energéticas, determinar alguns custos associados ao processo e simular o funcionamento da unidade com diferentes temperaturas de ar ambiente (cenários de verão e inverno com temperaturas médias de 20ºC e 5ºC). Os resultados revelaram uma diminuição de 1,14 €/h no custo da electricidade e um aumento do consumo de gás natural de 62,47 €/h durante o período mais frio no inverno devido ao aumento das perdas provocadas pela diminuição da temperatura exterior. Com esta nova unidade de cogeração compacta a poupança total anual pode ser, em média, de 267 780 € admitindo um valor para a manutenção de 97 698 €/ano. Se assim for, o projeto apresenta um retorno do investimento ao fim de 5 anos, com um VAL de 1 030 430 € e uma taxa interna de rentabilidade (TIR) de 14% (positiva, se se considerar a taxa de atualização do investimento de 3% para 15 anos de vida). Apesar do custo inicial ser elevado, os parâmetros económicos mostram que o projeto tem viabilidade económica e dará lucro durante cerca de 9 anos.
