Abstract:
In order to mitigate problems associated with environmental pollution, alkali-activated nickel slags (AANSs) may be used as an alternative to cementitious material. However, the understanding of their mechanical properties and microstructure is currently very limited. This paper therefore explores the influence of different types and contents of three solid alkali activators, Na2SiO3, NaOH, and Na2SiO3/Na2CO3, on the compressive strength of one-part AANS. Their microstructure, hydration components, and pore structure are analyzed by means of a scanning electron microscope, an energy-dispersive spectrometer, an X-ray diffractometer, an infrared spectrometer, and a mercury analyzer. The results show that the AANS with an Na2SiO3/Na2CO3 activator has a denser microstructure, lower porosity, and a smaller pore size when compared with the AANS with the Na2SiO3 or NaOH activators. Consequently, the compressive strength of the Na2SiO3/Na2CO3 sample reached a higher compressive strength (96 MPa) than that activated by Na2SiO3 or NaOH. This strength is optimal as well as more economical as Na2O, which increased from 0.107 mol to 0.123 mol, contributes little to compressive strength. The final part of the article discusses an optimal design for the engineering application of one-part AANS.

Abstract:
✓ The AANS was founded in 1931 as an educational and scientific organization whose principal purpose was to foster optimum neurosurgical care. Because socioeconomic and political pressures on medicine generally and neurosurgery specifically have escalated in recent years, the American Association of Neurological Surgeons (AANS) has been required to respond effectively to matters beyond its traditional role. However, the AANS has lacked an effective, focused policymaking process to deal with socioeconomic concerns despite existing expertise within the specialty. The AANS now needs to develop a comprehensive socioeconomic effort that is consistent with its more traditional educational and scientific activities. A Task Force on Governance has been appointed to address how the Association's governance structure can reflect all the needs of our specialty in times of economic uncertainty and health care reform.

Abstract:
OBJECTIVE Closing the knowledge gap that exists between patients and health care providers is essential and is facilitated by easy access to patient education materials. Although such information has the potential to be an effective resource, it must be written in a user-friendly and understandable manner, especially when such material pertains to specialized and highly technical fields such as neurological surgery. The authors evaluated the accessibility, usability, and reliability of current educational resources provided by the American Association of Neurological Surgeons (AANS), Healthwise, and the National Institute for Neurological Disorders and Stroke (NINDS). METHODS Online neurosurgical patient education information provided by AANS, Healthwise, and NINDS was evaluated using the LIDA scale, a website quality assessment tool, by medical professionals and nonmedical professionals. A high achieving score is regarded as 90% or greater using the LIDA scale. RESULTS Accessibility scores were 76.7% (AANS), 83.3% (Healthwise), and 75.0% (NINDS). Average usability scores for the AANS, Healthwise, and NINDS were 73.3%, 82.6%, and 82.9%, respectively, when evaluated by medical professionals and 78.5%, 80.7%, and 75.9%, respectively, for nonmedical professionals, respectively. Average reliability scores were 58.5%, 53.3%, 72.6%, respectively, for medical professionals and 70.4%, 66.7%, and 78.5%, respectively, for nonmedical professionals when evaluating the AANS, Healthwise, and NINDS websites. CONCLUSIONS Although organizations like AANS, Healthwise, and NINDS should be commended for their ongoing commitment to provide health care–oriented materials, modification of this material is suggested to improve the patient education value.

Abstract:
The primary purpose of the relationship between neurosurgery and industry must be to improve patient care and advance medical knowledge. This relationship is desirable and can be mutually beneficial. Strict adherence to established ethical and legal guidelines is necessary to avoid financial conflicts of interest that may occur between neurosurgery and industry. The Code of Ethics established by the American Association of Neurological Surgeons (AANS) in 1986 emphasizes the physician's responsibility to always act in the best interest of his or her patients. The AANS Guidelines for Corporate Relations were developed in 2004 to address the concern of the potential growing influence of industry in the activities of our neurosurgical organization. Recognizing a need to clarify the proper relationships between neurosurgeons and industry, Guidelines on Neurosurgeon-Industry Conflicts of Interest were recently established. The AANS is committed to the highest ethical and legal standards in future relations with our industry partners. Members of the AANS are encouraged to adhere to the voluntary guidelines established by our organization.

Abstract:
Object. The goal of this study was to create a searchable database of research manuscripts authored by members of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons (AANS/CNS) to describe the nature and character of the research currently being undertaken by neurosurgeons. Methods. Manuscripts published by all physician members listed in the 2001 AANS/CNS Membership Directory (6921 physicians) were gathered into a database through individual literature searches of the author name for the calendar year 2001. Duplicate publications were purged and the database was reviewed for accuracy. An internal verification of the database revealed a 4% underreporting rate. Statistics from the database were compiled and displayed with information about AANS/CNS members and their clinical activities. The AANS/CNS members published a total of 2748 research the manuscripts in 479 different journals during 2001. Thirty-eight percent of the manuscripts (1042 of 2748) were authored by US members and 62% (1706 of 2748) by non-US members. The focus of the majority of manuscripts included the areas of brain tumor (26%; 707 of 2748), vascular disease (20%; 558 of 2748), spine (10%; 282 of 2748), and trauma (8%; 233 of 2748). Sixty-nine percent of manuscripts (1897 of 2748) were retrospective and technical clinical studies, and of these 39% (744 of 1897) were case reports. Laboratory investigations made up 15% (414 of 2748) of all manuscripts, whereas prospective randomized clinical trials represented 1% (34 of 2748). Conclusions. The majority of AANS/CNS member manuscripts are authored by non—US members despite their small AANS/CNS representation. Most research is clinical, based on retrospective data, and includes a large number of case reports. A disparity exists between what neurosurgeons do clinically and both the quantity and subject of their research.

Abstract:
OBJECTIVEBoth the American Association of Neurological Surgeons/Congress of Neurological Surgeons Joint Section on Pediatric Neurological Surgery (AANS/CNS Pediatric Section) and the International Society for Pediatric Neurosurgery (ISPN) annual meetings provide a platform for pediatric neurosurgeons to present, discuss, and disseminate current academic research. An ultimate goal of these meetings is to publish presented results in peer-reviewed journals. The purpose of the present study was to investigate the publication rates of oral presentations from the 2009, 2010, and 2011 AANS/CNS Pediatric Section and ISPN annual meetings in peer-reviewed journals.METHODSAll oral presentations from the 2009, 2010, and 2011 AANS/CNS Pediatric Section and ISPN annual meetings were reviewed. Abstracts were obtained from the AANS/CNS Pediatric Section and ISPN conference proceedings, which are available online. Author and title information were used to search PubMed to identify those abstracts that had progressed to publication in peer-reviewed journals. The title of the journal, year of the publication, and authors’ country of origin were also recorded.RESULTSOverall, 60.6% of the presented oral abstracts from the AANS/CNS Pediatric Section meetings progressed to publication in peer-reviewed journals, as compared with 40.6% of the ISPN presented abstracts (p = 0.0001). The journals in which the AANS/CNS Pediatric Section abstract-based publications most commonly appeared were Journal of Neurosurgery: Pediatrics (52%), Child’s Nervous System (11%), and Journal of Neurosurgery (8%). The ISPN abstracts most often appeared in the journals Child’s Nervous System (29%), Journal of Neurosurgery: Pediatrics (14%), and Neurosurgery (9%). Overall, more than 90% of the abstract-based articles were published within 4 years after presentation of the abstracts on which they were based.CONCLUSIONSOral abstract presentations at two annual pediatric neurosurgery meetings have publication rates in peer-reviewed journal comparable to those for oral abstracts at other national and international neurosurgery meetings. The vast majority of abstract-based papers are published within 4 years of the meeting at which the abstract was presented; however, the AANS/CNS Pediatric Section abstracts are published at a significantly higher rate than ISPN abstracts, which could indicate the different meeting sizes, research goals, and resources of US authors compared with those of authors from other countries.

Abstract:
Papain was labelled by attachment of the fluorescent groups 2-(4′-acetamidoanilino)naphthalene-6-sulphonic acid (AANS) or N-(acetylaminoethyl)-8-naphthylamine-1-sulphonic acid (AEDANS) to the active-site cysteine residue, with the aim of using the labelled papains as probes in competitive titrations of unlabelled cysteine proteinases with their inhibitors. The interaction between the labelled papains and cystatins was accompanied by an increase in fluorescence emission of up to 38-fold for AANS-papain and approximately 3.5-fold for AEDANS-papain. Fluorescence titrations gave dissociation equilibrium constants of 3.1 and 0.6 microM for the binding of chicken cystatin and recombinant human cystatin C respectively to AANS-papain and of 11.9 microM for the binding of chicken cystatin to AEDANS-papain. The kinetics of interaction of chicken cystatin with AANS-papain showed an unusual biphasic dependence of the observed pseudo-first-order rate constant on inhibitor concentration, consistent with the reaction occurring via both pathways of a general two-step binding mechanism. AANS-papain was selected as the most suitable probe for competitive titrations of unlabelled active or inactivated cysteine proteinases with inhibitors. This technique, which provides stoichiometries and dissociation constants for the interaction between unlabelled enzyme and inhibitor, allows monitoring of the interactions by a large fluorescent signal in a wavelength region where the interacting proteins do not contribute to the observed fluorescence. Such competitive titrations of active papain or actinidin with chicken cystatin or recombinant human cystatin C all gave inhibitor/enzyme stoichiometries of close to 1.0. A dissociation constant of 1.8 microM for the reaction of chicken cystatin with a papain derivative, S-[N-(3-carboxypropyl)succinimidyl]-papain, was also determined by the same technique. These results show the usefulness of the fluorescent papains for the characterization of interactions between cysteine-proteinase inhibitors and their target enzymes.

Abstract:
There is an abundance of historical and anecdotal material relating to the experiences of the Australian soldier during World War 1. These soldiers were conscious both during and after the war that their contribution was important and that it was recognised as such by Australian society at large. Conversely there is an almost total absence of historical or anecdotal material about the role of the Australian nurse who served during this same conflict. Whether these nurses had the same degree of consciousness, either during or after the war, that their contributions were valued or seen as important by Australian society remains, largely, unknown. This thesis attempts to redress, in part, this absence by telling the story of a nurse, Jessie Tomlins, who served in the Australian Army Nursing Service during this period. At the same time specific aspects of the historical events surrounding World War One will be explored. Jessie Tomlins served, first as a Staff Nurse and later as a Sister, in the 14th Australian General Hospital in Egypt during 1916. At the same time her brother, Fred Tomlins, was already serving in the 1st Australian Light Horse Regiment and spent the entire four years of World War 1 in Palestine and Egypt. At the end of 1916 their younger brother, Will Tomlins, also joined the Army and became a member of the Anzac Mounted Division. The letters, postcards and photographs that Jessie, Fred and Will sent home to their mother and family, as well as Fred's fourteen diaries, form the foundation of this thesis. This thesis provides a meaningful snapshot of one woman from rural Australia who completed her nurse training during the war and then served her country during one of the most brutal periods of humankind. Her own words clearly tell the story of her war time experiences whilst, at the same time, conveying her expectations, prior to, during and after, this event. The development of the Australian Army Nursing Service, as it affected Jessie, over this period is also considered. It will be demonstrated that whilst ordinary men, soldiers, were at the military front line so too were ordinary women, nurses. The thesis will provide support for the contention that the contribution of Australian nurses in World War One, especially that of the ordinary nurse caring for the ordinary soldier, has been poorly recorded and as a result remains under-valued.

This research follows three directions which aim at reviewing the scholarship and debates about work in the services producing industries. The first direction assesses the specificity of work in services. Both the consequences of the service theory (productivity, "servuction") and the effects of the tertiarization upon the social structure (dualism, quality of job created) are examined. The second direction lays down four systems of tertiary employment. The typology rests on a factorial analysis and a examination on monographic works addressing supermarkets, banks and hospitals in the two countries. The third direction deals with the results of an international comparison. In this respect, the dissertation firstly provides statistical tools. Subsequently, it lays stress on similarities and differences in the structuration of tertiary employment in the two countries

Abstract:
Nas últimas décadas houve um grande avanço em pesquisas no desenvolvimento de medicamentos à base de plantas medicinais. Entretanto, constata-se que há pouca preocupação sobre as concentrações de elementos estáveis, bem como as concentrações de atividade de radionuclídeos naturais das séries do 238U e 232Th em plantas com esta finalidade no Brasil. A presença de minerais e radionuclídeos em plantas constitui um meio de migração destes elementos para o organismo humano, através da ingestão de chás ou medicamentos feitos com ervas medicinais. Peperomia pellucida é conhecida popularmente por erva de jabuti e por suas propriedades medicinais, como cicatrizante, analgésica, bactericida e fungicida. As amostras de Peperomia pellucida e de solo analisadas neste trabalho foram coletadas no Jardim Botânico do Rio de Janeiro e em suas proximidades. A concentração elementar de As, Ba, Br, Ce, Cl, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Mg, Mn, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb e Zn foi determinada nas folhas, partes aéreas, compreendendo folhas e caule, e raiz de Peperomia pellucida, nos extratos obtidos por maceração e infusão e no solo pela técnica da Análise por Ativação Neutrônica Instrumental (AANI). O método analítico utilizado para determinar os elementos Cd, Hg e Pb foi a Espectrometria por Absorção Atômica e as atividades de 226Ra, 228Ra e 210Pb foram determinadas pela contagem alfa e beta total após separação radioquímica. A qualidade dos resultados obtidos foi verificada pela análise dos materiais de referência certificados IAEA-336 Lichen, IAEA-Soil-7, IAEA-326 Radionuclides in soil, NIST 1515 Apples Leaves e NIST 1542 Peach Leaves. Os resultados obtidos nas análises apresentaram boa precisão e exatidão. O óleo essencial e os extratos etanólico e hexânico obtidos das partes aéreas de P. pellucida foram testados in vitro, em placas de Petri, para verificar a atividade antifúngica diante ao fungo Aspergillus flavus. A atividade antifúngica baseou-se na zona de inibição e nos valores de CI50 frente ao patógeno. Também foi determinada a composição química do óleo essencial pela Cromatografia Gasosa acoplada ao Espectrômetro de Massa (GC-EM).
In recent decades, there has been a great advancement in research in developing drugs from plants. Nevertheless, little significant care exists in the literature about the stable concentration of elements, as well as the activity concentration of 238U and 232Th decay products in plants used for this purpose in Brazil. The presence of stable elements and radionuclides in plants constitutes the pathway for their migration to humans, via uptake of tea or remedies made with medicinal herbs. Peperomia pellucida, whose popular name is erva de jabuti, is a plant known by its medicinal usages, such as healing and analgesic properties plus antibacterial and antifungal activities against food fungi. In this study, the elemental composition of Peperomia pellucida and surrounding soil samples collected in the Botanical Garden in Rio de Janeiro was determined; the elemental concentration in the alcoholic extract and infusion processes of dry plants was also determined. The elemental concentration of As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn was determined in the leaves, aerial parts, including leaves, stems and roots of Peperomia pellucida, in their extracts obtained by maceration and infusions and in the surrounding soil by the Instrumental Neutron Activation Analysis (INAA). The analytical methodology used to determine the elements Cd, Hg and Pb was the Atomic Absorption Spectrometry (AAS); the activities of 226Ra, 228Ra and 210Pb were carried out by gross alpha and beta counting, after radiochemical separation. The quality of the obtained results was assured by the analyses of the certified reference materials IAEA-336 Lichen, IAEA-Soil-7, IAEA-326 Radionuclides in soil, NIST 1515 Apple Leaves and NIST 1542 Peach Leaves. The relative standard deviations and the relative errors obtained in these analyses indicated good precision and accuracy of the results. The essential oil, ethanolic and hexane extracts of Peperomia pellucida were tested for antifungal activity against Aspergillus flavus in vitro on Petri plates. The antifungal activity was based on the inhibition zone and IC50 values against the pathogen on Petri plates assays. Also, the essential oil chemical composition was determined by GC-MS.

Abstract:
O presente estudo consiste na utilização de ferramentas nucleares com o intuito de fornecer um procedimento alternativo para realização de análises bioquímicas em sangue que possam auxiliar no diagnóstico de patologias diversas. O objetivo é medir a ocorrência de metais e íons em sangue total de humanos, via ativação neutrônica, disponibilizando os limites de normalidade bem como as correlações entre eles. Para realização deste estudo 283 amostras de sangue total foram analisadas (doadas de indivíduos selecionados em bancos de sangue) obtendo-se os limites de normalidade para: Br (0,0067 - 0,0263 gl-1), Cl (2,54 - 3,50 gl-1), K (1,33 - 1,89 gl-1) e Na (1,48 - 2,06 gl-1). Esses dados constituem as primeiras estimativas realistas para valor de referência em sangue total da população brasileira. Esses limites foram avaliados em função do sexo e idade permitindo salientar as diferenças biológicas. Os limites obtidos para Br, Cl, K e Na foram avaliados também entre diferentes populações, isto é, para duas regiões distintas: Sudeste (coleta realizada na cidade de São Paulo) e Nordeste (coleta realizada na cidade de Recife), locais escolhidos em função das similaridades (cidades de grande porte e industrializadas). Adicionalmente, foi realizado um estudo sistemático desses limites, no período de 4 (quatro) anos, na cidade de São Paulo; para esta finalidade a coleta foi realizada em função do tempo, dada a necessidade de atualização desses dados, pois esses elementos atuam como monitores ambientais. Estimativas para Ca e Fe foram também propostas para um conjunto de 22 amostras de sangue total.
The present study consists of using nuclear tools aiming to establish an alternative procedure to perform biochemistry analyses in whole blood to help the diagnosis of diverses pathologies. The aim is to determine the íons and metals concentrations in whole blood of human beings (specifically: Br, Cl, K e Na), using neutron activation analysis, providing the limits of normality, as well as, the matrix of the correlation for these elements. To perform this study, 283 samples of whole blood had been analyzed (of healthy volunteers selected from blood banks), resulting in the limits of normality for Br (0.0067 - 0.0263 gl-1), Cl (2.54 - 3.50 gl-1), K (1.33 - 1.89 gl-1) and Na (1.48 - 2.06 gl-1). These data are the first estimates for reference values in whole blood of the Brazilian population. These limits were evaluated in function of the sex and age for checking the biological differences. The behavior of these limits was also evaluated for different populations, i.e., in two distinct regions: Southeast (blood collection carried out in São Paulo city) and Northeast (blood collection carried out in Recife city). These places were chosen in function of the similarities (cities with high concentration people and industrialized). Futhermorer, a systematic study of these limits was also evaluated, in the period of 4 (four) years, in São Paulo city. This analysis was elaborated in function of time due the necessity to update these data, therefore they act as monitorial ambient. The estimation for Ca and Fe were also proposal for a set of 22 samples of whole blood.

The technological, material and economical transformations that have marked the last decades changed the way that people create, store and share information due to the progress achieved by ICT (Information and Communication Technology). The objective of this dissertation is to test the new paradigm of Cloud Computing, from which new virtual architectures are built as on-­‐demand services, involving creative processes and new communication procedures in digital environments. To do so, the dissertation proposes the principle of AaaS (Art as a Service) as an update to the discussions about art and media, exposing the recent transformations operating in the boundaries of media derivatives. The research presents an interdisciplinary bibliography which transits between studies in communication, art and culture. In conceptual terms, it departs from the understanding of artmedia, proposed by Arlindo Machado (2009), from the concepts of world-­‐culture and hypermodernity pointed by Gilles Lipovetsky and Jean Serroy (2010) and from the studies of the post-­‐media condition, elaborated by art critic Rosalind Krauss (2000). The research corpus is composed by experiments on ambient, materiality and image but without holding on to specific media or genres. These are analysed, not only from a theoretical point of view, but also from a practical methodology which testing the cloud-­‐map configuration in the second chapter. In line with these movements, we sought to collaborate with the network of critics, curators, artists, producers and institutions that have launched a new view on the theme, identifying the confluences and incompatibilities between the diverse fields involved
As transformações tecnológicas, materiais e econômicas que marcaram as últimas décadas, mudaram a forma como as pessoas criam, armazenam e compartilham informação por conta dos avanços encabeçados pela ITC (Tecnologia da Informação e Comunicação). O objetivo desta dissertação é testar o novo paradigma da Cloud Computing, a partir do qual novas arquiteturas virtuais são construídas na forma de serviços sob demanda, envolvendo processos de criação e novos procedimentos para se comunicar em ambientes digitais. Para tanto, a dissertação propõe o princípio AaaS (Art as a Service) como um update para as discussões sobre a relação entre arte e mídia, explicitando transformações recentes que operam nas fronteiras dos derivados da mídia. A pesquisa apresenta uma bibliografia interdisciplinar que transita entre autores da area de comunicação e dos estudos da cultura e da arte. Em termos conceituais, parte do entendimento de artemídia, proposto por Arlindo Machado (2009), dos conceitos de cultura-­‐mundo e hipermodernidade, apontados por Gilles Lipovetsky e Jean Serroy (2010) e dos estudos da condição pós-­‐mídia, elaborados pela crítica de arte Rosalind Krauss (2000). O corpus da pesquisa é composto por experimentos que exploram a relação entre ambiente, materialidade e imagem, sem se ater a suportes ou gêneros específicos. Estes são analisados, não apenas do ponto de vista teórico, mas a partir de uma metodologia prática que testa a configuração de mapas-­‐nuvens no segundo capítulo. Em sintonia com estes movimentos, buscamos colaborar com a rede de críticos, curadores, artistas, produtores e instituições fomentadoras que vem lançando um novo olhar sobre o tema, identificando as confluências e incompatibilidades entre os diversos campos envolvidos

Abstract:
AbstractBoth poultry meat and eggs provide high-quality animal protein [containing sufficient amounts and proper ratios of amino acids (AAs)] for human consumption and, therefore, play an important role in the growth, development, and health of all individuals. Because there are growing concerns about the suboptimal efficiencies of poultry production and its impact on environmental sustainability, much attention has been paid to the formulation of low-protein diets and precision nutrition through the addition of low-cost crystalline AAs or alternative sources of animal-protein feedstuffs. This necessitates a better understanding of AA nutrition and metabolism in chickens. Although historic nutrition research has focused on nutritionally essential amino acids (EAAs) that are not synthesized or are inadequately synthesized in the body, increasing evidence shows that the traditionally classified nutritionally nonessential amino acids (NEAAs), such as glutamine and glutamate, have physiological and regulatory roles other than protein synthesis in chicken growth and egg production. In addition, like other avian species, chickens do not synthesize adequately glycine or proline (the most abundant AAs in the body but present in plant-source feedstuffs at low content) relative to their nutritional and physiological needs. Therefore, these two AAs must be sufficient in poultry diets. Animal proteins (including ruminant meat & bone meal and hydrolyzed feather meal) are abundant sources of both glycine and proline in chicken nutrition. Clearly, chickens (including broilers and laying hens) have dietary requirements for all proteinogenic AAs to achieve their maximum productivity and maintain optimum health particularly under adverse conditions such as heat stress and disease. This is a paradigm shift in poultry nutrition from the 70-year-old “ideal protein” concept that concerned only about EAAs to the focus of functional AAs that include both EAAs and NEAAs.

Abstract:
This study investigates the application of nonlinear Principal Component Analysis (PCA), implemented through the use of Auto-Associative Neural Network (AANN), for early warning of impending gas turbine failure. The study is based on a real operational data set that includes a compressor failure. The analyzed data set consists of measured operational parameters whose identity are unknown, hence this study presents a purely data driven approach to the problem of early warning. In this case study, the use of AANNs for early detection of abnormal engine behavior could have provided the operator with a warning a few days prior to the fully developed failure, which resulted in a forced shut-down and extensive maintenance. Furthermore, a comparison is made between the nonlinear PCA by AANNs and the standard PCA model, which is an inherently linear method. The result shows that the AANN provides a more reliable detection of the failure by a higher residual generation during failure mode as well as fewer false indications prior to the failure. Consequently, this study shows that nonlinear PCA as performed with AANNs can be a valuable data driven tool for early warning of gas turbine failure.

Abstract:
Actualmente, la búsqueda de materiales cementantes eco-eficientes y sostenibles es un reto obligado, con el fin de adaptar el sector de la construcción hacia un tipo de economía circular y sostenible. Estos materiales, además, deben cumplir una serie de requisitos de prestaciones mecánicas, durables y de trabajabilidad que los haga competitivos. Dentro de estos materiales eco-eficientes, destacan los sistemas de cementos activados alcalinamente (Alkali-Activated Materials, AAMs), con muy buenas prestaciones mecánicas y durabilidad, pero cuya reología y trabajabilidad no están suficientemente estudiados. En trabajos previos se ha determinado que el comportamiento reológico de pastas y morteros de escorias y cenizas activadas alcalinamente (AAS y AAFA) depende de la naturaleza y la concentración del activador alcalino. Asimismo se corroboró que la trabajabilidad de los morteros AAS y AAFA es más sensible a los cambios en la relación líquido/sólido que los morteros de OPC. Sin embargo hay parámetros cuya influencia sobre la reología de estos morteros de AAMs están por determinar, como son la granulometría y naturaleza del árido en el sistema. Se han preparado morteros con una relación árido/ligante 2:1 variando el diámetro máximo del árido (0.5, 1 y 2 mm) y la naturaleza del mismo (silíceo, calizo y remplazamiento parcial por árido reciclado). Los morteros de AAS se activaron con una disolución de silicato sódico hidratado (waterglass) (módulo SiO2/Na2O de 1.5 y 4% de Na2O sobre peso de escoria), mientras que los de cenizas volantes se activaron con una disolución de NaOH 10M. Se elaboraron igualmente morteros de OPC con el fin de comparar con un sistema tradicional. La trabajabilidad de los morteros se evaluó a partir de la prueba de fluidez y se han realizado ensayos de Stress Growth Test y determinación de parámetros reológicos por el ensayo del Flow curve test. Los resultados han mostrado, en primer lugar, que la fluidez de los morteros de AAMs presenta mayor variación con el tamaño de árido, frente a los morteros de OPC. De igual manera, la naturaleza del árido afecta a la demanda de líquido y a la fluidez de dichos morteros. Además, la disminución del tamaño máximo de los áridos, produce en todos los casos un aumento en el valor del esfuerzo umbral de cizalla estático y dinámico, así como de la viscosidad plástica. Por último, se ha constatado que los morteros de OPC, AAS y AAFA se ajustan al modelo reológico de Bingham, independientemente de la naturaleza y diámetro máximo de partícula del árido.DOI: http://dx.doi.org/10.4995/HAC2018.2018.6002

Abstract:
Abdominal Aortic Aneurysms (AAAs) are localized enlargements of the aorta. If untreated, AAAs will grow irreversibly until rupture occurs. Ruptured AAAs are usually fatal and are a leading cause of death in the United States, killing 15,000 per year (National Center for Health Statistics, 2001). Surgery to repair AAAs also carries mortality risks, so surgeons desire a reliable tool to evaluate the risk of rupture versus the risk of surgery.
