ANÁLISE COMPARATIVA DOS NÍVEIS DE ATRITO EM BRÁQUETES CONVENCIONAIS E AUTOLIGADOS

O atrito existente entre bráquetes e os fios ortodônticos é um fator importante a ser considerado quanto à eficiência do tratamento ortodôntico nas mecânicas de deslize. Em função disto, sempre se procurou maneiras de se diminuir os níveis de atrito durante a aplicação deste tipo de mecânica. Com o surgimento dos bráquetes autoligados, observou-se que uma das características principais destes dispositivos seria uma redução dos níveis de atrito entre os bráquetes e fios, e com isso poderia se obter um movimento de deslizamento eficiente com a aplicação de forças menores, quando comparado com o uso de bráquetes que tenham sistemas de amarração convencionais. O propósito deste trabalho foi comparar, por meio de ensaios laboratoriais, os níveis de atrito estático de um bráquete autoligado estético, de um bráquete autoligado metálico e dois tipos de bráquetes convencionais metálicos, com a utilização de fios ortodônticos de diferentes ligas, secção e diâmetros, para determinar quais bráquetes apresentam os menores coeficientes de atrito, em situações sem angulação, em angulações de primeira ordem e angulações de segunda ordem entre os diferentes fios e bráquetes. Os resultados demonstraram que os bráquetes autoligados apresentaram um atrito estático significativamente mais baixo nas situações onde não existiu angulação entre o fio e o bráquete e quando se utilizou fios de calibres menores e com material mais flexível, quando comparados com os bráquetes convencionais. O bráquete autoligado metálico apresentou maior atrito, semelhante aos bráquetes convencionais, com o uso dos fios de maior calibre, nas situações sem angulação. O bráquete autoligado metálico apresentou maior atrito estático que os bráquetes convencionais, nas situações de angulação, com o uso dos fios de maior calibre

Avaliação das inclinações dentárias obtidas no tratamento ortodôntico com bráquetes autoligados utilizando tomografia computadorizada

O objetivo deste trabalho foi analisar a expressão dos torques dentários em pacientes tratados com aparelhos ortodônticos fixos com bráquetes autoligados, utilizando tomografias computadorizadas. Para este estudo, foi selecionada uma amostra clínica de 10 pacientes, seguindo como critérios de inclusão, indivíduos que apresentavam dentição permanente e todos os dentes presentes, com apinhamento superior ou igual a 4 mm, tratados sem extração. Todos os pacientes foram tratados na clínica da pós-graduação em Ortodontia da Universidade Metodista de São Paulo, utilizando-se bráquetes autoligados Damon 2 ORMCO na prescrição padrão. Foram realizadas medições das inclinações dos dentes anteriores, de canino a canino, superiores e inferiores, realizadas por meio de imagens tomográficas obtidas em um tomógrafo computadorizado volumétrico NewTom, em seu modelo DVT-9000 (NIM Verona - Itália), obtidas em dois tempos: antes do início do tratamento ortodôntico (denominado de T1) e depois do tratamento ortodôntico, após a inserção do último fio de nivelamento, de calibre 0,019 x 0,025 de aço inoxidável(denominado de T2). Para auxílio destas mensurações, foi utilizado o software QR-DVT 9000 e após análise dos resultados foram aplicados testes estatíscos (testes "t" pareado e Dalberg) e observou-se que as inclinações dos dentes do segmento anterior aumentaram, principalmente, nos caninos e incisivos laterais superiores, incisivos centrais e laterais inferiores. Os dentes apresentaram valores de inclinação diferentes da prescrição, tanto no início quanto no final do tratamento, denotando a incapacidade do fio 0,019 x 0,025 de aço inoxidável em reproduzir os torques indicados na prescrição padrão utilizada neste presente estudo.(AU)

The growing importance of inter-company collaboration

Guest editorial: This special issue has been drawn from papers that were published as part of the Second European Conference on Management of Technology (EuroMOT) which was held at Aston Business School (Birmingham, UK) 10-12 September 2006. This was the official European conference for the International Association for Management of Technology (IAMOT); the overall theme of the conference was “Technology and global integration.” There were many high-calibre papers submitted to the conference and published in the associated proceedings (Bennett et al., 2006). The streams of interest that emerged from these submissions were the importance of: technology strategy, innovation, process technologies, managing change, national policies and systems, research and development, supply chain technology, service and operational technology, education and training, small company incubation, technology transfer, virtual operations, technology in developing countries, partnership and alliance, and financing and investment. This special issue focuses upon the streams of interest that accentuate the importance of collaboration between different organisations. Such organisations vary greatly in character; for instance, they may be large or small, publicly or privately owned, and operate in manufacturing or service sectors. Despite these varying characteristics they all have something in common; they all stress the importance of inter-organisational collaboration as a critical success factor for their organisation. In today's global economy it is essential that organisations decide what their core competencies are what those of complementing organisations are. Core competences should be developed to become a bases of differentiation, leverage and competitive advantage, whilst those that are less mature should be outsourced to other organisations that can claim to have had more recognition and success in that particular core competence (Porter, 2001). This strategic trend can be observed throughout advanced economies and is growing strongly. If a posteriori reasoning is applied here it follows that organisations could continue to become more specialised in fewer areas whilst simultaneously becoming more dependent upon other organisations for critical parts of their operations. Such actions seem to fly in the face of rational business strategy and so the question must be asked: why are organisations developing this way? The answer could lie in the recent changes in endogenous and exogenous factors of the organisation; the former emphasising resource-based issues in the short-term, and strategic positioning in the long-term whilst the later emphasises transaction costs in the short-term and acquisition of new skills and knowledge in the long-term. For a harmonious balance of these forces to prevail requires organisations to firstly declare a shared meta-strategy, then to put some cross-organisational processes into place which have their routine operations automated as far as possible. A rolling business plan would review, assess and reposition each organisation within this meta-strategy according to how well they have contributed (Binder and Clegg, 2006). The important common issue here is that an increasing number of businesses today are gaining direct benefit from increasing their levels of inter-organisational collaboration. Such collaboration has largely been possible due to recent technological advances which can make organisational structures more agile (e.g. the extended or the virtual enterprise), organisational infra-structure more connected, and the sharing of real-time information an operational reality. This special issue consists of research papers that have explored the above phenomenon in some way. For instance, the role of government intervention, the use of internet-based technologies, the role of research and development organisations, the changing relationships between start-ups and established firms, the importance of cross-company communities of practice, the practice of networking, the front-loading of large-scale projects, innovation and the probabilistic uncertainties that organisations experience are explored in these papers. The cases cited in these papers are limited as they have a Eurocentric focus. However, it is hoped that readers of this special issue will gain a valuable insight into the increasing importance of collaborative practices via these studies.

An evaluation of motivations for studying pharmacy, career commitment and future career plans

It has been predicted that there will be a full time pharmacist workforce shortage of over 15,000 by 2013. It is therefore necessary to recruit more students of a suitable calibre to undergraduate pharmacy degree courses. This study was designed to investigate the motivations of pre-university and MPharm students for studying pharmacy. A series of focus groups was conducted with Year 12 students and a national survey of Year 13, 1st year MPharm and 4th year MPharm students was undertaken. The study found that amongst Year 12 students, pharmacy is perceived as a background profession and was also perceived as being of a lower status than medicine and dentistry. It was concluded that there was a need for greater promotion of pharmacy as a career amongst pre-university students, including the provision of structured work experience placements. Analysis of UCAS applicant data for pharmacy shows that the applicant pool is buoyant and that the majority of applicants are female. Female respondents to the surveys were significantly more likely than males to wish to work part time if they had a family. This could lead to further shortages in the full time workforce. The largest ethnic group of applicants to pharmacy degree courses were Asian. Business ownership and self-employment were motivations for entering the procession of pharmacy and career aims for significantly more Asian than White respondents. Ownership of independent pharmacies is declining and this could be a barrier to future recruitment to pharmacy degree courses. A high degree of interest in locum working may present a problem for continuity in commissioned services within community pharmacy practice. Further work is needed to examine the motivations for working as a locum pharmacist.

The clinical assessment of systemic hypertension in optometric practice

This thesis sets out to examine in detail the condition of systemic hypertension (high Blood Pressure) in relation to optometric practice in the United Kingdom. Systemic hypertension, which is asymptomatic in the early stages, is diagnosed from the Blood Pressure (BP) measurement recorded by a sphygmomanometer and/or from the complications that have developed in target organs. Optometric practice based surveys revealed that diagnosed systemic hypertension was the most prevalent cardiovascular medical condition (20.5%). Measurement of BP of patients in this sample revealed that if an optometrist included sphygmomanometry into the sight examination then at least one patient each day would be referred for suspect systemic hypertension. Optometric opinion felt that the measurement of BP in optometric practice would advance the profession, being appreciated by both patients and General Practitioners (GPs), but was felt to be an unnecessary routine procedure. The present sight examination for the systemic hypertensive is similar to that of the normotensive patient, but may involve an altered fundus examination and a visual field test. The GPs were in favour of optometric BP measurement and a future role in the share care management of the systemic hypertensive. The application of a new pictorial grading scale for the grading of vascular changes associated with pre-malignant systemic hypertension was found to be both accurate and reliable. Clinical trial of the grading scale in optometric practice found positive correlations between BP and increasing severity of the retinal vascular features. The subtle pre-malignant vascular changes require reliable accurate detection and analysis to assist in the management of the systemic hypertensive patient. Vessel width was shown to decrease with increasing age. Image analysis of the A/V ratio, arteriolar tortuosity and focal calibre changes revealed a positive correlation to the patient's BP (p<0.001). The retinal vasculature is relatively stable longitudinally with only minor changes in response to early disease states. Age and elevated BP increased a patient's risk of developing systemic medical conditions over a two-year period. The application of the pictorial grading scale to optometric practice and training the optometrist in the use of sphygmomanometry would improve the management of the systemic hypertensive patient in optometric practice. Future advances in image analysis hold substantial benefits for the detection and monitoring of subtle vascular changes associated with systemic hypertension.

Improving the description of the retinal vasculature and patient history taking for monitoring systemic hypertension

Systemic hypertension is an important public health concern. If optometrists are to perform a more active role in the detection and monitoring of high blood pressure (BP), there is a need to improve the consistency of describing the retinal vasculature and to assess patient's ability to correctly report the diagnosis of hypertension, its control and medication. One hundred and one patients aged >40 years were dilated and had fundus photography performed. BP was measured and a self-reported history of general health and current medication was compared with the records of their general practitioner (GP). The status of the retinal vasculature was quantified using a numeric scale by five clinicians and this was compared to the same evaluation performed with the aid of a basic pictorial grading scale. Image analysis was used to objectively measure the artery-to-vein (A/V) ratio and arterial reflex. Arteriolar tortuosity and calibre changes were found to be the most sensitive retinal signs of high BP. Using the grading scale to describe the retinal vasculature significantly improved inter- and intra-observer repeatability. Almost half the patients examined were on medication for high BP or cardiovascular disease. Patients' ability to give their complete medical history was poor, as was their ability to recall what medication they had been prescribed. GPs indicated it was useful to receive details of their patient's BP when it was >140/90 mmHg. The use of improved description of the retinal vasculature and stronger links between optometrists and GPs may enhance future patient care. © 2001 The College of Optometrists.

Comparison of subjective and objective methods to determine the retinal arterio-venous ratio using fundus photography

Purpose: To assess the inter and intra observer variability of subjective grading of the retinal arterio-venous ratio (AVR) using a visual grading and to compare the subjectively derived grades to an objective method using a semi-automated computer program. Methods: Following intraocular pressure and blood pressure measurements all subjects underwent dilated fundus photography. 86 monochromatic retinal images with the optic nerve head centred (52 healthy volunteers) were obtained using a Zeiss FF450+ fundus camera. Arterio-venous ratios (AVR), central retinal artery equivalent (CRAE) and central retinal vein equivalent (CRVE) were calculated on three separate occasions by one single observer semi-automatically using the software VesselMap (ImedosSystems, Jena, Germany). Following the automated grading, three examiners graded the AVR visually on three separate occasions in order to assess their agreement. Results: Reproducibility of the semi-automatic parameters was excellent (ICCs: 0.97 (CRAE); 0.985 (CRVE) and 0.952 (AVR)). However, visual grading of AVR showed inter grader differences as well as discrepancies between subjectively derived and objectively calculated AVR (all p < 0.000001). Conclusion: Grader education and experience leads to inter-grader differences but more importantly, subjective grading is not capable to pick up subtle differences across healthy individuals and does not represent true AVR when compared with an objective assessment method. Technology advancements mean we no longer rely on opthalmoscopic evaluation but can capture and store fundus images with retinal cameras, enabling us to measure vessel calibre more accurately compared to visual estimation; hence it should be integrated in optometric practise for improved accuracy and reliability of clinical assessments of retinal vessel calibres. © 2014 Spanish General Council of Optometry.

Contabilidade do crescimento pelo lado da demanda agregada: uma proposta de cálculo das contribuições ao crescimento pela demanda agregada para o Brasil de, 2000 a 2009, utilizando matrizes insumo-produto

The demand side growth accounting studies the demand aggregate component contributions in the Gross Domestic Product (GDP). Traditionally, international and national organizations that uses the traditional method for calculating such contributions. However, this method does not take into account the effect the induction of imports by the various components of aggregate demand on the calculation of these. As an alternative to this method are presented others studies that consider this effect, as the alternative method proposed by Lara (2013), the attribution method, proposed by Kranendonk and Verbruggen (2005) and Hoekstra and van der Helm (2010), and the method the sraffian supermultiplier, by Freitas and Dweck (2013). Was made a summary of these methods, demonstrating the similarities and differences between them. Also, in the aim to contribute to the study of the subject was developed the “method of distribution of imports” that aims to distribute imports for the various components of aggregate demand, through the information set forth in the input-output matrices and tables of resources and uses. Were accounted the contributions to the growth of macroeconomic aggregates for Brazil from 2001 to 2009 using the method of distribution, and realized comparison with the traditional method, understanding the reasons for the differences in contributions. Later was done comparisons with all the methods presented in this work, between the calculated contributions to the growth of the components of aggregate demand and the domestic and external sectors. Was verified that the methods that exist in the literature was not enough to deal with this question, and given the alternatives for contributions to the growth presented throughout this work, it is believed that the method of distribution provides the best estimates for the account of contributions by aggregate demand sector. In particular, the main advantage of this method to the others is the breakdown of the contribution of imports, separated by aggregate demand component, which allows the analysis of contribution of each component to GDP growth. Thus, this type of analysis helps to study the pattern of growth of the Brazilian economy, not just the theoretical point of view, but also empirical and basis for the decision to economic policies

Desenvolvimento de um painel sanduíche com carga de particulado oriundo de resíduo lignocelulósico para aplicação em produtos na área de equipamentos de proteção

This work aims to study and investigate the use of a hybrid composite polymer formed with blanket aramid (Kevlar 29) fiber blanket flax fiber and particulate dry endocarp of coconut (Cocos nucifera Linn), using as matrix an epoxy resin based thermoset for use in areas of protective equipment. Besides such material is used an aluminum plate, joined to the composite by means of glue based on epoxy and araldite commercial. The manufacturing process adopted was manual lamination (Hand Lay Up) to manufacture the hybrid composite. After the composite is prepared, an aluminum plate is subjected to pressure and glued to cure the adhesive. Layers of veil will also be used to separate the particulate from the linen blanket layer without disturbing the alignment of the fibers of the blankets. To characterize the mechanical and physical behavior was manufactured a plate of 800 x 600 mm of the hybrid composite, which were removed specimens for tests of water absorption to saturation; density; impact test (Charpy) and two test specimens for ballistic testing 220 mm x 200 mm to make a comparative study between the dry state and saturated water absorption and thus see the ballistic performance of these two conditions. The test was applied to make a comparative study of fracture in these two conditions, caused by penetrating ballistic missile (38 and 380). To test the impact (Charpy) will analyze the absorbed energy, fracture appearance and lateral contraction, also in dry condition and saturation of absorbed water, thereby analyzing situations where the impact load is relevant, such as bumps and shocks produced by stone, metal or wooden bars among others. The proposed configuration, along with the tests, has the purpose, application in the fields of equipment against ballistic impact, such as helmets; bullet proof vests; shields; protective packaging and other items to be identified in this research.

Efeito da densidade de sementeira nos componentes de rendimento do tremoço branco (Lupinus albus L.)

O tremoço branco (Lupinus albus L.) é utilizado na alimentação animal e humana. Com este trabalho pretendeu-se avaliar o efeito de duas densidades de sementeira (20 e 40 sementes/m2, respectivamente) na produtividade e nos componentes do rendimento de um ecótipo de tremoço branco. O campo experimental foi instalado na Quinta do Galinheiro (ESAS) Santarém, de acordo com um delineamento experimental em parcelas totalmente aleatórias, com 4 repetições. Foram efetuadas observações bissemanais do desenvolvimento e crescimento através da amostragem aleatória de 8 plantas em cada um dos tratamentos (número de folhas, ramificações e vagens por planta; número médio de grãos por vagem e por planta; peso seco de cada componente e o total da planta; peso de 1000 grãos e teor de proteína do grão). Observaram-se perdas importantes de plantas entre a sementeira e a emergência. O maior crescimento e produtividade individual das plantas na menor densidade, relativamente à maior, justificaram os valores muito aproximados verificados entre os dois tratamentos quando são consideradas as variáveis por unidade de área. Os teores de proteína e calibre do grão foram também idênticos nos dois tratamentos. Confirma-se assim a elevada capacidade da planta em se adaptar a diferentes densidades.

Avaliação da fertilização azotada na produtividade e qualidade da variedade Hermes para indústria

O azoto é determinante na produtividade e na qualidade da batata para indústria. Com este trabalho pretendeu-se avaliar o efeito de diferentes doses de azoto na variedade de batata “Hermes”, em plena condições de cultivo do Vale do Tejo. Os tratamentos consistiram na aplicação de 0 (N0), 80 (N80), 160 (N160), 240 (N240) e 320 (N320) kg de azoto/ha, na forma de ENTECÒ 26. O ensaio foi instalado em parcelas totalmente aleatórias, com 4 repetições. Foi registado semanal a taxa de cobertura de solo pelo método da grelha até à sua cobertura total. Bissemanalmente, foram recolhidas plantas nos tratamentos N0 (0kgN/ha) e N160 (160kgN/ha) para avaliação do seu desenvolvimento e crescimento. No final do ciclo cultural avaliou-se a produção total, comercial, em peso e número de tubérculos. Avaliou-se ainda o peso específico, os teores em matéria seca dos tubérculos e a percentagem do azoto total na matéria seca das folhas e tubérculos. A adubação azotada influenciou a dimensão do aparelho fotossintético, através do estímulo de ramificações. Verificou-se uma maior produtividade de tubérculos nos tratamentos com maior aplicação de azoto, embora os acréscimos tenham sido menores a partir dos 160kg/ha. O azoto influenciou a percentagem de tubérculos de maior calibre.

La protection de la vie privée au temps de la biosécurité

Cette thèse s’intéresse à la protection de la vie privée informationnelle dans le contexte de la biosécurité. La biosécurité se définit comme le processus qui vise à prendre en charge, dans une optique de sécurité nationale, les menaces et dangers que représentent les épidémies de maladies infectieuses pour la santé des populations humaines et la sécurité de l’État. Notre projet remet en question l’idée selon laquelle la conduite des activités de surveillance de la santé publique implique nécessairement une diminution de la protection offerte aux renseignements personnels sur la santé. Nos recherches tendent à démontrer que la conciliation de la surveillance de la santé et la protection de la vie privée est non seulement possible, mais qu’elle est surtout nécessaire. Nous portons plus précisément notre attention sur le cas de la collecte et de l’utilisation de renseignements dépersonnalisés sur la santé par les systèmes de surveillance syndromique. Bien calibrée et soigneusement réglementée, cette forme novatrice et particulière de surveillance offrirait le double avantage de réduire les risques d’atteintes à la vie privée des individus et d’augmenter de manière considérable l’efficacité des capacités étatiques en matière de détection des épidémies.
