Review of the Regulatory Requirements for the Maintenance of Aerobic Treatment Units and Greywater Treatment Systems in Western Australia  [PDF]
Tessa McGrath, Natalia Shishkina, Richard Theobald, Clemencia Rodriguez
Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.717124
Abstract: Aerobic Treatment Units (ATU) and Greywater Treatment Systems (GTS) are onsite wastewater treatment systems (OWTS) designed to treat wastewater to secondary effluent quality standards. Consequently, the electrical, mechanical and chemical components of these OWTS need to be regularly maintained to ensure their consistent and reliable operation to the required standards. In Western Australia (WA), the Department of Health set out the regulatory requirements for the maintenance of OWTS as well as when and how it is to occur. This paper reviews the maintenance requirements for ATU and GTS in WA and provides recommendations for the proposed changes in guidelines and regulations. State and national guidelines were reviewed and information from industry and regulators was obtained through surveys. The review found that although the guidelines are generally satisfactory there are a number of areas which could be improved and specific recommendations are discussed.
Dioxins, Furans and PCBs in Recycled Water for Indirect Potable Reuse
Clemencia Rodriguez,Angus Cook,Brian Devine,Paul Van Buynder,Richard Lugg,Kathryn Linge,Philip Weinstein
International Journal of Environmental Research and Public Health , 2008, DOI: 10.3390/ijerph5050356
Abstract: An assessment of potential health impacts of dioxin and dioxin-like compounds in recycled water for indirect potable reuse was conducted. Toxic equivalency factors (TEFs) for 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDFs) and dioxin-like polychlorinated biphenyls (PCBs) congeners have been developed by the World Health Organization to simplify the risk assessment of complex mixtures. Samples of secondary treated wastewater in Perth, Australia were examined pre-and post-tertiary treatment in one full-scale and one pilot water reclamation plant. Risk quotients (RQs) were estimated by expressing the middle-bound toxic equivalent (TEQ) and the upper-bound TEQ concentration in each sampling point as a function of the estimated health target value. The results indicate that reverse osmosis (RO) is able to reduce the concentration of PCDD, PCDF and dioxin-like PCBs and produce water of high quality (RQ after RO=0.15). No increased human health risk from dioxin and dioxin-like compounds is anticipated if highly treated recycled water is used to augment drinking water supplies in Perth. Recommendations for a verification monitoring program are offered.
Indirect Potable Reuse: A Sustainable Water Supply Alternative
Clemencia Rodriguez,Paul Van Buynder,Richard Lugg,Palenque Blair,Brian Devine,Angus Cook,Philip Weinstein
International Journal of Environmental Research and Public Health , 2009, DOI: 10.3390/ijerph6031174
Abstract: The growing scarcity of potable water supplies is among the most important issues facing many cities, in particular those using single sources of water that are climate dependent. Consequently, urban centers are looking to alternative sources of water supply that can supplement variable rainfall and meet the demands of population growth. A diversified portfolio of water sources is required to ensure public health, as well as social, economical and environmental sustainability. One of the options considered is the augmentation of drinking water supplies with advanced treated recycled water. This paper aims to provide a state of the art review of water recycling for drinking purposes with emphasis on membrane treatment processes. An overview of significant indirect potable reuse projects is presented followed by a description of the epidemiological and toxicological studies evaluating any potential human health impacts. Finally, a summary of key operational measures to protect human health and the areas that require further research are discussed.
Regulatory Schemes and Investment Behavior in Transmission of Electricity: The Case of Argentina Regulatory Schemes and Investment Behavior in Transmission of Electricity: The Case of Argentina
Clemencia Torres
Revista de Análisis Económico (RAE) , 1995,
Abstract: The objective of this paper is to analyze the impact of the Argentinian regulation of the expantion of the network for high voltage electricity. Argentina reorganized its electricity industry in 1992, including the transmission network and adopted a new regulatory framework. The result for investment in transmission have been mixed so far. The new regulation apparently have not triggered the investment necessary to eliminate local bottlenecks in the transmission system. The persistence of this problems hinders the capability of the industry to ensure reliable and economical electricity in the long run. This paper attemps to explain the reasons for these mixed results.

Aspectos humanos en el manejo del paciente terminal
Uribe Clemencia
Avances en Enfermería , 1990,
Abstract: Durante 10 a os consecutivos, he tenido la oportunidad de acompa ar a muchas personas en el penoso trámite, de la última y definitiva enfermedad, que los ha llevado hasta el cese de la vida. He observado y compartido las emociones, afectos y sentimientos, que el paciente ha tratado de transmitir, al presentir la muerte inminente. Puedo asegurar que el sentimiento más asiduo del moribundo, es el miedo, muchas veces enmascarado en un riguroso silencio, que lo confina a la exclusión. Otras veces, se aleja de la realidad, envuelto en agresivas actitudes, que lo disipan de su arraigada desesperanza.
Del mundo del texto al mundo del lector (Ricoeur y Cortázar)
Ardila J,Clemencia;
Co-herencia , 2010,
Abstract: an interpretation of two authors, namely paul ricoeur and julio cortázar, is presented in this essay with respect to a couple of pieces of his respective works, namely, tiempo y narración and babas del diablo. the purpose is to show how, in one hand, the presentation of hermeneutic concepts is reflected in the text of cortazar and, in other hand, how the fragments of the story allow the intellection of the concepts of ricoeur.
CRIOCONSERVACIóN: EFECTOS SOBRE LA MOVILIDAD ESPERMáTICA Y LA FERTILIZACIóN EN PECES
Pardo Carrasco Sandra Clemencia
Acta Biológica Colombiana , 2010,
Abstract: La crioconservación de semen en peces, como en muchas especies, presenta aún efectos que disminuyen la calidad espermática y comprometen directamente la capacidad de la célula para participar exitosamente en los procesos de fertilización y desarrollo embrionario. Características como movilidad y capacidad de fertilización del espermatozoide son consideradas como criterios de calidad que permiten medir el éxito o fracaso del proceso, pues se consideran variables integradoras, siendo indicadores que dependen no de un solo factor sino de la estabilidad y bienestar del conjunto de estructuras, enzimas y compuestos funcionales subcelulares que dan lugar a estas características espermáticas. Da os en la membrana (adenilato ciclasa, canales iónicos, agrupamiento de otras proteínas, entre otras) y su implicación en la ruta de se alización que da lugar a la activación espermática, degradación del ATP, fragmentación del ADN nuclear y mitocondrial (genoma), degradación de enzimas Kinasas y otras proteínas citosólicas (proteoma) son considerados hoy día como algunos de los factores moleculares que más se afectan durante la crioconservación y que disminuyen ostensiblemente la capacidad fertilizante y la movilidad del espermatozoide en los peces. Propuestas sobre los mecanismos moleculares por los cuales se interrelacionan y actúan estos factores subcelulares como consecuencia de la crioconservación, son algunos de los temas tratados en la presente revisión. Comprender los principios y factores que están involucrados en el origen de dichos da os, permitirá mejorar los procesos de crioconservación, haciéndolos menos nocivos y más eficientes.

El fin de la guerra.
María Clemencia Castro.
Affectio Societatis , 1999,
Abstract: En la guerra, lucha armada y sangrienta entre agrupaciones organizadas, está expuesto el sujeto en una escena sin tiempo donde la principal invitada es la muerte. Se concreta allí la conjunción del ideal y del imperativo superyoico, encontrándose más allá del deseo, el goce. Cuando flaquea el ideal, se esclarece lo ominoso del nexo con la destrucción y la muerte.
