Trustworthiness: self-assessment of an institutional repository against ISO 16363-2012

Today, almost every document we create and the output from almost every research-related project, is a digital object. Not everything has to be kept forever, but materials with scholarly or historical value should be retained for future generations. Preserving digital objects is more challenging than preserving items on paper. Hardware becomes obsolete, new software replaces old, storage media degrades. In recent years, there has been significant progress made to develop tools and standards to preserve digital media, particularly in the context of institutional repositories. The most widely accepted standard thus far is the Trustworthy Repositories Audit and Certification: Criteria and Checklist (TRAC), which evolved into ISO 16363-2012. Deakin University Library undertook a self-assessment against the ISO 16363 criteria. This experience culminated in the current report, which provides an appraisal of ISO 16363, the assessment process, and advice for others considering embarking on a similar venture.

Análise da ABNT NBR ISO 14005:2012 como instrumento de implementação de sistemas de gestão ambiental em pequenas e médias empresas

The use of environmental management systems - EMS has shown to be a key tool for addressing the environmental aspects and impacts of an organization. The vast majority of EMS based on the requirements of ISO 14001:2004, as it is a globally recognized standard and adopt its recommendations is considered to be a guarantee of fulfilling the basic requirements of an EMS. Despite all the benefits that the system provides, we still find many problems in the implementation of EMS, especially in small and medium enterprises or SME. Most of the difficulties of implementation is related to intrinsic factors that companies of this size have, and issues related to the models and methods used to implement an EMS. Thus, this work aimed to assess whether the guidelines of ISO 14005:2012 meet the needs of SMEs for the effective implementation of an environmental management system. For it has been identified in the relation between SMEs and EMS the majof intrinsic problems of SMEs to implement (PII), such as lack of financial and human resources, and lack of commitment from top management to the SGA. Also was also pointed the main implementation issues related to ISO 14001 (ABNT, 2004) or the models or methods (PIM), highlighting the lack of environmental performance criteria, and the need for a path or sequence of steps for implementation. The study of ISO 14005 (ABNT, 2012) showed that the standard guidelines and implementation examples proposed, include solutions for all problems related to EMS implementation SMEs

Relationship between quality certification and financial and non-financial performance of organizations

At present, many countries have either embraced ISO9001 or used it as the basis of their national quality certification systems. However, few studies have been conducted to examine the benefits companies’ gain from achieving and implementing ISO9001 standards (Chikuku et al. 2012; Psomas et al. 2013; Sampaio et al. 2011a,b). Analysis has brought much more confused and uneven results across the countries. Turning to the experience of Malaysia, this country has witnessed a spectacular growth at an average rate of 9.89% per annum of ISO certificates issued to companies operating within its borders (ISO Survey 2012). While many companies rush to be ISO 9001 certified whether this brings about better benefits (both the financial and the non-financial) is still an open question. In this study, the research problems were first formulated from the literature and then a questionnaire survey was conducted to test the hypotheses. A survey was administered to chief executives officers and managers across manufacturing and service organizations in Malaysia. Multivariate analysis and SPSS macro developed by Preacher and Hayes were used as statistical techniques to the financial and non-financial benefits of ISO9001 certification. The survey instrument was a two-page questionnaire comprising three sections. The first section of the questionnaire covered the company’s profile. The second section consisted of 25 items on internal benefits and third section consisted of 7 items on external benefits measured on 1–5 Likert scale to assess the benefits of ISO9001 certification. Total 201 valid responses were received. Results of the study indicate that there was no significant direct relationship between ISO9001 certification and organizational financial performance, while strong statistical evidence was found to support the direct relationship between ISO9001 certification and non-financial performance. The findings of the study discovered that financial performance is actually directly related to two non-financial measures, namely quality performance and local and international business performance, which are directly and significantly influenced by ISO9001 certification. Therefore non-financial performance measures are involved in the mediational process. The findings will assist practitioners in taking right courses of action that make the implementation of this standard more effective. For example, the study findings study suggests that companies should put emphasize on nonfinancial factors to improve their financial performance.

Immunohistochemistry should undergo robust validation equivalent to that of molecular diagnostics

Immunohistochemistry (IHC) is a widely available and highly utilised tool in diagnostic histopathology and is used to guide treatment options as well as provide prognostic information. IHC is subjected to qualitative and subjective assessment, which has been criticised for a lack of stringency, while PCR-based molecular diagnostic validations by comparison are regarded as very rigorous. It is essential that IHC tests are validated through evidence-based procedures. With the move to ISO15189 (2012), not just of the accuracy, specificity and reproducibility of each test need to be determined and managed, but also the degree of uncertainty and the delivery of such tests. The recent update to ISO 15189 (2012) states that it is appropriate to consider the potential uncertainty of measurement of the value obtained in the laboratory and how that may impact on prognostic or predictive thresholds. In order to highlight the problems surrounding IHC validity, we reviewed the measurement of Ki67and p53 in the literature. Both of these biomarkers have been incorporated into clinical care by pathology laboratories worldwide. The variation seen appears excessive even when measuring centrally stained slides from the same cases. We therefore propose in this paper to establish the basis on which IHC laboratories can bring the same level of robust validation seen in the molecular pathology laboratories and the principles applied to all routine IHC tests.

Definição de um modelo de integração dos sistemas de gestão, da qualidade, do ambiente e da segurança, aplicado ao setor da cerâmica

A integração dos vários SsG que a organização pretenda implementar, contribui para a simplificação ao nível da sua gestão e aumento da eficácia. No entanto, a integração de múltiplos SsG pode acarretar alguma complexidade, quer na fase da implementação propriamente dita, quer ao nível da sua posterior gestão, caso o processo não seja conduzido de forma rigorosa. Considerando a escassez de diretivas orientadoras para a integração de SsG e a dificuldade de integração no momento da sua implementação, a presente dissertação propõe um modelo de integração dos SsGQAS, aplicado ao setor da cerâmica. Os referenciais normativos utilizados para o desenvolvimento do estudo foram: a NP EN ISO 9001: 2008, a NP EN ISO 14001: 2012, a BS OHSAS 18001: 2007/NP 4397:2008 e a UNE 66177:2005, com base nos quais se definiu um modelo de integração para os SsGQAS.Numa primeira fase procedeu-se à análise da perceção dos colaboradores da organização face às vantagens, desvantagens, motivações e dificuldades da implementação do SIGQAS, efetuada através de inquérito por questionário. Desta análise conclui-se que são percetíveis para os colaboradores da Aleluia Cerâmicas S.A., as vantagens / melhorias para a organização decorrentes da integração dos SsG. Por fim, procedeu-se à definição do modelo de integração dos SsGQAS. O modelo baseou-se na metodologia proposta pela UNE 66177, que contempla orientações para o desenvolvimento, implementação e avaliação do processo de integração dos SsGQAS. Esta dissertação tem como objetivo auxiliar as organizações a gerir de forma eficaz as diretrizes dos diferentes referenciais normativos e a obterem benefícios resultantes da sua integração, alcançando maior eficácia na sua gestão e aumento de rentabilidade.

Chemical characterization and bioactivity of epoxy resin and Portland cement-based sealers with niobium and zirconium oxide radiopacifiers

The purpose of this study was to characterize and to evaluate the bioactivity potential of experimental root canal sealers (ES) based on Portland cement, epoxy resin with nano- and micro-particles of niobium or zirconium oxide used as radiopacifiers in comparison to AH Plus and MTA Fillapex. Methods Specimens of the sealers (10 mm in diameter × 1 mm thick) were prepared and the radiopacity was evaluated according to ISO 6876 (2012) specifications. Characterization of the sealers was performed under the scanning electron microscope (SEM) immediately after setting and after immersion for 28 days in Hank's balanced salt solution (HBSS). In addition X-ray energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy were also performed. The pH and calcium ion release were measured after 1, 7, 14, 21 and 28 days after completion of seating using a digital pH meter and an atomic absorption spectrophotometer, respectively. Results The experimental sealers exhibited an average radiopacity of 2.5 mm thickness of aluminum, which was similar to MTA Fillapex (P > 0.05) and inferior to AH Plus (P < 0.05). AH Plus did not show bioactivity. Although the experimental sealers did not exhibit the formation of hydration product, they encouraged the deposition of crystalline spherical structures of calcium deficient phosphate. The highest pH and calcium release values were observed with the experimental sealers (P < 0.01). ES-Nb-micro was the only sealer to present hexagonal shaped crystal deposition. Significance Novel root canal sealers based on a mixture of Portland cement, epoxy resin and radiopacifier exhibited a degree of bioactivity although no evidence of cement hydration was demonstrated on material characterization. The radiopacifier particle size had limited effect on the sealer microstructure and chemical properties.

Sintesi e proprietà di biochar da biomasse residuali

Il termine biochar definisce il prodotto solido derivante dalla pirolisi di un qualsiasi materiale organico, con lo specifico scopo di essere applicato nei suoli sia per fini agronomici che di gestione ambientale. Un suo utilizzo in maniera "responsabile" richiede però una piena comprensione delle sue proprietà e dei meccanismi che controllano la sua attività nel terreno, che dipendono dalla biomassa di partenza e dalle condizioni di sintesi tramite pirolisi. Infatti le condizioni di pirolisi, in particolare la temperatura di processo e il tempo di residenza, determinano biochar con caratteristiche differenti. In questo lavoro di tesi sono stati prodotti biochar da due diverse tipologie di biomassa residuale ampiamente disponibili (stocchi di mais e pollina). Per ciascuna biomassa sono state scelte tre condizioni di pirolisi (400°C x 20 minuti, 500°C x 10 minuti e 600°C x 5 minuti). Sui biochar ottenuti sono state effettuate le seguenti determinazioni: analisi elementare, Pirolisi‐GC‐MS, idrocarburi policiclici aromatici (IPA), acidi grassi volatili (VFA), azoto ammoniacale (N‐NH4 +), pH, conduttività elettrica e ritenzione idrica. Infine i biochar sintetizzati sono stati utilizzati per fare due test di germinazione per valutare l'effetto sulla formazione delle prime strutture di crescita delle plantule, tramite test di tossicità brevi con piastre Petri. Il primo test è stato condotto a concentrazione crescente di miscele acqua/biochar (2, 5, 40 e 100 g/L sulla base delle quantità di biochar utilizzate come ammendante nel suolo), sulla germinazione seguendo la metodologia normata dalla ISO 11269:2012. I semi utilizzati nel primo test sono stati quelli del crescione (Lepidium sativum L.) come specie dicotiledone, e del sorgo (Sorghum saccharatum M.) come monocotiledone. Il secondo saggio di tossicità eseguito è stato quello descritto dalla normativa in materia UNI 11357, valutando l'eventuale effetto di tossicità alla massima concentrazione delle varie tipologie di biochar, utilizzando come specie dicotiledoni il cetriolo (Cucumis sativus L.) ed il crescione (Lepidium sativum L.), come monocotiledone il sorgo (Sorghum saccharatum M.). Per i biochar da stocchi di mais, rappresentativi di biomasse erbacee e con diverso grado di carbonizzazione, non si osservano effetti apprezzabili alle condizioni di uso agricolo. Nel caso dei biochar da pollina si osservano invece inibizioni alla germinazione sin dalle concentrazioni più basse. In particolare, quello pirolizzato a 400°C mostra un potenziale effetto tossico più marcato, probabilmente associato ad un contenuto di IPA e VFA superiore a quello degli altri biochar.

El análisis de la construcción sin pérdidas (Lean Construction) y su relación con el Project & Construction Management : propuesta de regulación en España y su inclusión en la ley de la ordenación de la edificación

El presente trabajo se basa en la filosofía de la Construcción sin Pérdidas (“Lean Construction”), analizando la situación de esta filosofía en el sector de la edificación en el contexto internacional y español, respondiendo las siguientes preguntas: 1. ¿Cómo surge el “Lean Construction”? 2. ¿Cuáles son sus actividades, funciones y cometidos? 3. ¿Existe regulación del ¨Lean Construction” en otros países? 4. ¿Existe demanda del ¨Lean Construction” en España? 5. ¿Existe regulación del ¨Lean Construction” en España? 6. ¿Cómo debería ser la regulación ¨Lean Construction” en España? 7. ¿Cuál es la relación del “Lean Construction” con el “Project & Construction Management”? 8. ¿Cómo debería ser la regulación de “Lean Construction” en España considerando su relación con el “Project & Construction Management”? Las preguntas indicadas las hemos respondido detalladamente en el presente trabajo, a continuación se resume las respuestas a dichas preguntas: 1. El “Lean Construction” surge en agosto de 1992, cuando el investigador finlandés Lauri Koskela publicó en la Universidad de Stanford el reporte TECHNICAL REPORT N° 72 titulado “Application of the New Production Philosophy to Construction”. Un año más tarde el Dr. Koskela invitó a un grupo de especialistas en construcción al primer workshop de esta materia en Finlandia, dando origen al International Group for Lean Construction (IGLC) lo que ha permitido extender la filosofía a EEUU, Europa, América, Asia, Oceanía y África. “Lean Construction” es un sistema basado en el enfoque “Lean Production” desarrollado en Japón por Toyota Motors a partir de los años cincuenta, sistema que permitió a sus fábricas producir unidades con mayor eficiencia que las industrias americanas, con menores recursos, en menor tiempo, y con un número menor de errores de fabricación. 2. El sistema “Lean Construction” busca maximizar el valor y disminuir las pérdidas de los proyectos generando una coordinación eficiente entre los involucrados, manejando un proyecto como un sistema de producción, estrechando la colaboración entre los participantes de los proyectos, capacitándoles y empoderándoles, fomentando una cultura de cambio. Su propósito es desarrollar un proceso de construcción en el que no hayan accidentes, ni daños a equipos, instalaciones, entorno y comunidad, que se realice en conformidad con los requerimientos contractuales, sin defectos, en el plazo requerido, respetando los costes presupuestados y con un claro enfoque en la eliminación o reducción de las pérdidas, es decir, las actividades que no generen beneficios. El “Last Planner System”, o “Sistema del Último Planificador”, es un sistema del “Lean Construction” que por su propia naturaleza protege a la planificación y, por ende, ayuda a maximizar el valor y minimizar las pérdidas, optimizando de manera sustancial los sistemas de seguridad y salud. El “Lean Construction” se inició como un concepto enfocado a la ejecución de las obras, posteriormente se aplicó la filosofía a todas las etapas del proyecto. Actualmente considera el desarrollo total de un proyecto, desde que nace la idea hasta la culminación de la obra y puesta en marcha, considerando el ciclo de vida completo del proyecto. Es una filosofía de gestión, metodologías de trabajo y una cultura empresarial orientada a la eficiencia de los procesos y flujos. La filosofía “Lean Construction” se está expandiendo en todo el mundo, además está creciendo en su alcance, influyendo en la gestión contractual de los proyectos. Su primera evolución consistió en la creación del sistema “Lean Project Delivery System”, que es el concepto global de desarrollo de proyectos. Posteriormente, se proponen el “Target Value Design”, que consiste en diseñar de forma colaborativa para alcanzar los costes y el valor requerido, y el “Integrated Project Delivery”, en relación con sistemas de contratos relacionales (colaborativos) integrados, distintos a los contratos convencionales. 3. Se verificó que no existe regulación específica del ¨Lean Construction” en otros países, en otras palabras, no existe el agente con el nombre específico de “Especialista en Lean Construction” o similar, en consecuencia, es un agente adicional en el proyecto de la edificación, cuyas funciones y cometidos se pueden solapar con los del “Project Manager”, “Construction Manager”, “Contract Manager”, “Safety Manager”, entre otros. Sin embargo, se comprobó la existencia de formatos privados de contratos colaborativos de Integrated Project Delivery, los cuales podrían ser tomados como unas primeras referencias para futuras regulaciones. 4. Se verificó que sí existe demanda del ¨Lean Construction” en el desarrollo del presente trabajo, aunque aún su uso es incipiente, cada día existe más interesados en el tema. 5. No existe regulación del ¨Lean Construction” en España. 6. Uno de los objetivos fundamentales de esta tesis es el de regular esta figura cuando actúe en un proyecto, definir y realizar una estructura de Agente de la Edificación, según la Ley de Ordenación de la Edificación (LOE), y de esta manera poder introducirla dentro de la Legislación Española, protegiéndola de eventuales responsabilidades civiles. En España existe jurisprudencia (sentencias de los tribunales de justicia españoles) con jurisdicción civil basada en la LOE para absolver o condenar a agentes de la edificación que son definidos en los tribunales como “gestores constructivos” o similares. Por este motivo, en un futuro los tribunales podrían dictaminar responsabilidades solidarias entre el especialista “Lean Construction” y otros agentes del proyecto, dependiendo de sus actuaciones, y según se implemente el “Lean Project Delivery System”, el “Target Value Design” y el “Integrated Project Delivery”. Por otro lado, es posible que el nivel de actuación del especialista “Lean Construcción” pueda abarcar la gestión del diseño, la gestión de la ejecución material (construcción), la gestión de contratos, o la gestión integral de todo el proyecto de edificación, esto último, en concordancia con la última Norma ISO 21500:2012 o UNE-ISO 21500:2013 Directrices para la dirección y gestión de proyectos. En consecuencia, se debería incorporar adecuadamente a uno o más agentes de la edificación en la LOE de acuerdo a sus funciones y responsabilidades según los niveles de actuación del “Especialista en Lean Construction”. Se propone la creación de los siguientes agentes: Gestor del Diseño, Gestor Constructivo y Gestor de Contratos, cuyas definiciones están desarrolladas en este trabajo. Estas figuras son definidas de manera general, puesto que cualquier “Project Manager” o “DIPE”, gestor BIM (Building Information Modeling), o similar, puede actuar como uno o varios de ellos. También se propone la creación del agente “Gestor de la Construcción sin Pérdidas”, como aquel agente que asume las actuaciones del “gestor de diseño”, “gestor constructivo” y “gestor de contratos” con un enfoque en los principios del Lean Production. 7. En la tesis se demuestra, por medio del uso de la ISO 21500, que ambos sistemas son complementarios, de manera que los proyectos pueden tener ambos enfoques y ser compatibilizados. Un proyecto que use el “Project & Construction Management” puede perfectamente apoyarse en las herramientas y técnicas del “Lean Construction” para asegurar la eliminación o reducción de las pérdidas, es decir, las actividades que no generen valor, diseñando el sistema de producción, el sistema de diseño o el sistema de contratos. 8. Se debería incorporar adecuadamente al agente de la edificación “Especialista en Lean Construction” o similar y al agente ¨Especialista en Project & Construction Management” o DIPE en la Ley de Ordenación de la Edificación (LOE) de acuerdo a sus funciones y responsabilidades, puesto que la jurisprudencia se ha basado para absolver o condenar en la referida Ley. Uno de los objetivos fundamentales de esta tesis es el de regular la figura del “Especialista en Lean Construction” cuando actúa simultáneamente con el DIPE, y realizar una estructura de Agente de la Edificación según la LOE, y de esta manera protegerlo de eventuales responsabilidades solidarias. Esta investigación comprueba que la propuesta de definición del agente de edificación DIPE, según la LOE, presentada en la tesis doctoral del Doctor Manuel Soler Severino es compatible con las nuevas definiciones propuestas. El agente DIPE puede asumir los roles de los diferentes gestores propuestos en esta tesis si es que se especializa en dichas materias, o, si lo estima pertinente, recomendar sus contrataciones. ABSTRACT This work is based on the Lean Construction philosophy; an analysis is made herein with regard to the situation of this philosophy in the building sector within the international and Spanish context, replying to the following questions: 1. How did the concept of Lean Construction emerge? 2. Which are the activities, functions and objectives of Lean Construction? 3. Are there regulations on Lean Construction in other countries? 4. Is there a demand for Lean Construction in Spain? 5. Are there regulations on Lean Construction in Spain? 6. How should regulations on Lean Construction be developed in Spain? 7. What is the relationship between Lean Construction and the Project & Construction Management? 8. How should regulations on Lean Construction be developed in Spain considering its relationship with the Project & Construction Management? We have answered these questions in detail here and the replies are summarized as follows: 1. The concept of Lean Construction emerged in august of 1992, when Finnish researcher Lauri Koskela published in Stanford University TECHNICAL REPORT N° 72 entitled “Application of the New Production Philosophy to Construction”. A year later, Professor Koskela invited a group of construction specialists to Finland to the first workshop conducted on this matter; thus, the International Group for Lean Construction (IGLC) was established, which has contributed to extending the philosophy to the United States, Europe, the Americas, Asia, Oceania, and Africa. Lean Construction is a system based on the Lean Production approach, which was developed in Japan by Toyota Motors in the 1950s. Thanks to this system, the Toyota plants were able to produce more units, with greater efficiency than the American industry, less resources, in less time, and with fewer manufacturing errors. 2. The Lean Construction system aims at maximizing the value of projects while reducing waste, producing an effective coordination among those involved; it manages projects as a production system, enhancing collaboration between the parties that participate in the projects while building their capacities, empowering them, and promoting a culture of change. Its purpose is to develop a construction process free of accidents, without damages to the equipment, facilities, environment and community, flawless, in accordance with contractual requirements, within the terms established, respecting budgeted costs, and with a clear approach to eliminating or reducing waste, that is, activities that do not generate benefits. The Last Planner System is a Lean Construction system, which by its own nature protects planning and, therefore, helps to maximize the value and minimize waste, optimizing substantially the safety and health systems. Lean Construction started as a concept focused on the execution of works, and subsequently the philosophy was applied to all the stages of the project. At present it considers the project’s total development, since the time ideas are born until the completion and start-up of the work, taking into account the entire life cycle of the project. It is a philosophy of management, work methodologies, and entrepreneurial culture aimed at the effectiveness of processes and flows. The Lean Construction philosophy is extending all over the world and its scope is becoming broader, having greater influence on the contractual management of projects. It evolved initially through the creation of the Lean Project Delivery System, a global project development concept. Later on, the Target Value Design was developed, based on collaborative design to achieve the costs and value required, as well as the Integrated Project Delivery, in connection with integrated relational (collaborative) contract systems, as opposed to conventional contracts. 3. It was verified that no specific regulations on Lean Construction exist in other countries, in other words, there are no agents with the specific name of “Lean Construction Specialist” or other similar names; therefore, it is an additional agent in building projects, which functions and objectives can overlap those of the Project Manager, Construction Manager, Contract Manager, or Safety Manager, among others. However, the existence of private collaborative contracts of Integrated Project Delivery was confirmed, which could be considered as first references for future regulations. 4. There is a demand for Lean Construction in the development of this work; even though it is still emerging, there is a growing interest in this topic. 5. There are no regulations on Lean Construction in Spain. 6. One of the main objectives of this thesis is to regulate this role when acting in a project, and to define and develop a Building Agent structure, according to the Building Standards Law (LOE by its acronym in Spanish), in order to be able to incorporate it into the Spanish law, protecting it from civil liabilities. In Spain there is jurisprudence in civil jurisdiction based on the LOE to acquit or convict building agents, which are defined in the courts as “construction managers” or similar. For this reason, courts could establish in the future joint and several liabilities between the Lean Construction Specialist and other agents of the project, depending on their actions and based on the implementation of the Lean Project Delivery System, the Target Value Design, and the Integrated Project Delivery. On the other hand, it is possible that the level of action of the Lean Construction Specialist may comprise design management, construction management and contract management, or the integral management of the entire building project in accordance with the last ISO 21500:2012 or UNE-ISO 21500:2013, guidelines for the management of projects. Accordingly, one or more building agents should be appropriately incorporated into the LOE according to their functions and responsibilities and based on the levels of action of the Lean Construction Specialist. The creation of the following agents is proposed: Design Manager, Construction Manager, and Contract Manager, which definitions are developed in this work. These agents are defined in general, since any Project Manager or DIPE, Building Information Modeling (BIM) Manager or similar, may act as one or as many of them. The creation of the Lean Construction Manager is also proposed, as the agent that takes on the role of the Design Manager, Construction Manager and Contract Manager with a focus on the Lean Production principles. 7. In the thesis it is demonstrated that through the implementation of the ISO 21500, both systems are supplementary, so projects may have both approaches and be compatible. A project that applies the Project & Construction Management may perfectly have the support of the tools, techniques and practices of Lean Construction to ensure the elimination or reduction of losses, that is, those activities that do not generate value, thus designing the production system, the design system, or the contract system. 8. The Lean Construction Specialist or similar and the Specialist in Project & Construction Management should be incorporated appropriately into the LOE according to their functions and responsibilities, since jurisprudence has been based on such Law to acquit or convict. One of the main objectives of this thesis is the regulate the role of the Lean Construction Specialist when acting simultaneously with the DIPE, and to develop a structure of the building agent, according to the LOE, and in this way protect such agent from joint and several liabilities. This research proves that the proposal to define the DIPE building agent, according to the LOE, and presented in the doctoral dissertation of Manuel Soler Severino, Ph.D. is compatible with the new definitions proposed. The DIPE agent may assume the roles of the different managers proposed in this thesis if he specializes in those topics or, if deemed pertinent, recommends that they be engaged.

Routine histological technique applied to a biological model for environmental studies

Introduction and aim Earthworms are an important test organisms used in several standard ecotoxicological tests (e.g. ISO, 2008, 2012; OECD, 2004, 1094) and they are also model organisms to test soil structure and permeability, as well as for important soil services as the degradation organic matter. Although histopathological changes have been demonstrated to be good biomarkers to assess the exposure of these animals to different physical and chemical stress agents, studies with clear and high quality images describing normal tissue conditions are scarce in the literature, so the aim of this work was to better characterize this biological model. Material and Methods Eight adult earthworms exposed to an artificial standard soil (OECD, 2004) for 28 days, were extracted and placed in a plastic box to depurate their gut content, fixed in 10% neutral-buffered formalin and processed for routine histopathological diagnosis. Results and discussion Satisfactory histological sections were obtained. Some difficulties were faced related with microtome sectioning, resulting in artefacts, namely lines across sections produced by a nick in the cutting edge of the microtome knife cutting tear, motivated by the presence of sand and other solid particles that persisted in the gut of earthworms. Nevertheless, it was possible to obtain representative figures from different earthworm sections. Conclusion Routine histological technique was effective for obtaining satisfactory histological sections and the knowledge of the histology of earthworms could be very useful for future application in environmental studies, using this biological model.
