Full textAbstract:
The study presents a review of in-service models and a search
for an effective in-service model for mathematics education in
the primary school.
The study considers the need to improve the teaching of
mathematics in the primary school; the major reports that have
made recommendations for the improvement of primary mathematics
teaching and the opinions and findings of mathematics
educators. The study examines the state of the art of
in-service models and examines those models previously used.
The study notes the failings of the in-service models past and
present and examines elements within these models which have
proven to be beneficial albeit in part. Throughout the study
particular attention is given to recent studies concerned with
implementing and sustaining change.
The model designed for the in-service of the primary mathematics
teacher, MINC (Mathematics In-service Network Course) is based
on an examination of models past and present. Components and
provisions that have met with success in these models were
included in the design.
The in-service model developed and described in this study
includes four major components input from course leaders and
teachers, reflection, feedback and the opportunity for teachers
to work with others from the same school and neighbouring
schools (networking).
A major section of the study examines the responses of
participants to an evaluation questionnaire given at the
completion of the first in-service course, MINC 1 and the
second, MINC 2.
Data collected from the responses of participants to the
questionnaire were analysed to see if there were differences in
responses from teachers based on such factors as sex, the MINC
network, the level to which participants had studied
mathematics, the year level they taught and expressed confidence
in teaching mathematics.
In conclusion, the study reflects on the evaluation of the
in-service course and addresses considerations for future
in-service courses concerned with mathematics education for
primary teachers.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO<br>COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR<br>O trabalho propõe uma metodologia para elaboração de modelos
geológicos e geomecânicos (3D) e realização de análises de
estabilidade (2D)de taludes rochosos de minas a céu aberto,
com base nos dados da mina de Morro da Mina, fornecidos pela
empresa VALE, a qual esta pertence. A metodologia está
dividida em duas etapas: modelagem e análises de
estabilidade. Para a modelagem, foi utilizado o software
Petrel 2004, que oferece ferramentas geoestatísticas,
possibilitando a extrapolação das informações geotécnicas
pontuais c`, fi, RQD, Q e RMR, obtidas por meio de
testemunhos de sondagem, para o maciço inteiro. Utilizou-se
a técnica de Krigagem Ordinária. O modelo gerado representou
bem a distribuição destas propriedades no espaço.
Na etapa de análise de estabilidade, foram utilizadas seções
resultantes da modelagem geomecânica. Dois tipos de análises
foram realizados: análises cinemáticas, com utilização do
software Dips, da Rocscience, e análises por
equilíbrio limite dos taludes globais e das bancadas,
utilizando-se o software Slide 5.0, também da Rocscience. No
primeiro tipo, realizado com dois conjuntos de mapeamentos
diferentes, foi constatado que as bancadas devem receber
bastante atenção nesta mina, e no segundo tipo, foi
verificada a segurança quanto à ruptura circular das
bancadas e taludes globais, porém recentemente ocorreu uma
ruptura em um dos locais analisados. Os programas RocData
4.0 e RocProp, ambos da Rocscience, foram utilizados para
estimar os parâmetros de resistência de Mohr-Coulomb, e os
softwares AutoCAD 2004 e Microsoft Office Excel auxiliaram
na preparação dos arquivos de entrada no Petrel 2004 e no
Slide 5.0.<br>This work presents a methodology to develop geological and
geomechanic models (3D) and to carry out stability analyses
(2D) of rock slopes of open pit mine, based on data of Morro
da Mina mine, provided by the mining company VALE. The
methodology is divided in two stages: modelling and
stability analyses. For the modelling, the software Petrel
2004, which allows the use of geostatistical tools, was
used, being possible the spatial distribution of
geotechnical information, obtained from borehole cores, for
the whole rock mass. The technique of Ordinary Kriging was
used. The modeled properties were the following: c`, fi,
RQD, Q e RMR. The generated model represented well the
spatial distribution of these properties. The stability
analyses were carried out using 2D sections and the
necessary rock mass parameters were obtained from
the geomechanical model. Two types of analyses were carried
out: kinematic analyses, with use of the software Dips, from
Rocscience, and limit equilibrium analyses of the global
slopes and the benches, where the software Slide 5.0, also
from Rocscience was used. The Kinematic analyses, carried
out considering two sets of joint orientations, suggested
that the benches have to receive enough attention in this
mine, and the limit equilibrium analyses for circular
failure of the benches and global slopes indicated high
factors of safety. However, before this work initiating a
failure already had happened in one of the sections
analyzed. The programs RocData 4.0 and RocProp, both from
Rocscience, were used to estimate the Mohr-Coulomb strength
parameters, and the programs AutoCAD 2004 and Microsoft
Office Excel helped at the development of the input files in
the Petrel 2004 and Slide 5.0.

Full textAbstract:
The present work had as aim a development and calibration of a small evaporation pan comparing its evaporation with class A pan and its capability to estimate the reference evapotranspiration comparing it with the Penman-Monteith equation. This tool has the finality to facilitate the irrigation control, not being necessary to sample or to install equipment in the field, thus decreasing work and material acquisition costs. Also, is intention whit this apparatus to not loose data at rainy days as occurs with the standard one (class A pan), make easier its management and reach closest estimates to reference evapotranspiration calculate by standard equation (Penman-Monteith). The development had consisted in a comparison, with patterns, of different phases in witch had used different hem, drain and water level height. The calibration had done by the adjusting of the values of reference evapotranspiration done through pan coefficient determination (Kpsm) contrasting small pan evaporation with standard evapotranspiration. Obtained results show a no significant correlation between characteristic height and pan performing expressed by c coefficient in relation to evaporation and evapotranspiration. Considering the SM pan capacity in estimate the rain height, is possible to correlate its performing to hem rising. In height lines we can consider, as average, that comparing whit class A pan, to five days average, the performing account as good and to ten days average as very good according to CAMARGO & CENTELHAS (1997) classification. At the comparison between the SM pan and Penman-Monteith methods, also as average, can be consider to five days average a performing account classify as ordinary and for ten days average as good . In case of rainy estimative, the performing rises from ordinary to excellent with the skirt rising. The regression coefficients - a and b statically disagree from its patterns - zero and one as rain as evapotranspiration estimates, pointing the necessity of these values correction. Whether considered the relation between SM and class A pans, these coefficients do not disagree from one and zero to ten days average, however using five days averages, the linear coefficient became disagree from zero. To make this corrections, meanwhile, is necessary a bigger data period to have more confidence values. In short, to obtained data, the small pan was capable to estimate well the evaporation measured at class A pan and the occurred rain and reasonable the reference evapotranspiration in spite of correction necessity. More over can be concluded that characteristic heights do not influence at evaporation and evapotranpirations values, but it does at the rain. It is known, however, this data are partial and to infer definitely on this tool efficiency it is necessary lengthen the experiment for some years and had placed at other sites.<br>O presente trabalho teve por objetivo desenvolver e calibrar um mini-tanque evaporimétrico, comparando sua evaporação com o tanque classe A e sua capacidade de estimar a evapotranspiração de referência com a equação de Penman-Monteith. Este aparelho tem a finalidade de facilitar o controle da irrigação, não necessitando amostragens ou instalação de equipamentos a campo, reduzir custos de mão-de-obra e aquisição de aparelhos sofisticados. Também é intenção com este mini-tanque, não perder leitura em dias de chuva, como ocorre com o evaporímetro padrão (tanque classe A ), facilitar seu manejo e alcançar estimativas mais próximas dos valores de evapotranspiração de referência calculadas através da equação padrão (Penman-Monteith). O desenvolvimento consistiu da comparação, com os padrões, de diferentes etapas em que usou-se diferentes alturas de borda, dreno e lâmina de água. A calibração deu-se pelo ajuste dos valores da evapotranspiração de referência, feita através da determinação dos coeficientes de tanque (Kpsm), confrontando-se os valores de evaporação do mini-tanque com a evapotranspiração de referência padrão. Os resultados obtidos mostram que não houve correlação significativa entre as variações das alturas característica dos mini-tanques e os desempenhos, expressados pelo coeficiente c , no que diz respeito à evaporação ou evapotranspiração. Quanto à capacidade do tanque SM estimar a precipitação ocorrida, pode-se correlacionar a melhora do seu desempenho com o aumento da borda. De modo geral pode-se considerar, em média, que na comparação com o tanque classe A , para médias qüinqüidiais, o conceito de desempenho como bom e para médias decendiais, como muito bom , de acordo com a classificação de CAMARGO & CENTELHAS (1997). Na comparação da evapotranspiração calculada pelo método do tanque SM com Penman-Monteith, também em média, pode-se considerar para médias qüinqüidiais um desempenho classificado como mediano e para decendiais, bom . No caso da estimativa da chuva, o desempenho passou de mediano à ótimo com o aumento da altura da borda. Os coeficientes de regressão - a e b - diferiram estatisticamente de seus parâmetros - zero e um tanto para a estimativa chuva como para a da evapotranspiração, indicando a necessidade de correção destes valores. Se consideradas as relações entre as evaporações do tanque SM e do classe A , estes coeficientes não diferem de zero e um para as médias decendiais, porém usando-se as qüinqüidiais, o coeficiente linear passa a diferir de zero. Para se fazer estas correções, no entanto, necessita-se de um maior número de dados para que se tenham valores mais confiáveis. Como conclusão tem-se que para os dados obtido o mini-tanque foi capaz de estimar bem as evaporações do tanque classe A e a precipitação ocorrida, e de forma razoável a evapotranspiração de referência, apesar da necessidade de correção dos valores. Além disso, pode-se concluir que as alturas características não influem nos valores da evaporação ou evapotranspiração, mas que têm correlação com a chuva. Sabe-se, porém que estes dados são parciais e que para inferir de forma definitiva sobre a eficácia deste aparelho, é necessário que se prolongue o experimento por mais alguns anos e que este seja instalado também em outros locais.

Full textAbstract:
This thesis describes the results of field based research on the Konkola (Bancroft) underground copper mine groundwater flow problem, in Zambia. Konkola is one of the wettest mines in the world, pumping an average of 360,000 m^/d of water. To understand how groundwater flows into and through the mine and subsequently formulate a long-term cost-effective groundwater management solution, an integrated study of historical and current dewatering and mining records, structural geology, surface hydrology, rock chemistry and groundwater chemistry, was carried out. The results enabled the development of a numerical model, to be used to make groundwater discharge and water level drawdown predictions for future groundwater management decisions. The results obtained clearly reveal that; mine water can be divided into that which originates from surface recharge close to the mine and that which originates from regional aquifers at depth. This has enabled the origin of water in the mine to be essentially established. A considerable percentage of the water entering the mine comes via the Hangingwall Aquifer with its connection to the surface sources of recharge. Flow to the mine is dominated by flow through fractures and fissures which form zones of high conductivity. The flow in these zones can be modelled by finite difference networks. Significant reduction of water inflow into the mine can be achieved by implementing a water-exclusion groundwater management solution.

Full textAbstract:
The purpose of this study is to assess the dewatering requirements of planned open pit nickel mining at Ç<br>aldag Site in Western Turkey. Dewatering is required for safe and efficient working conditions and pit wall stability. With this scope, a groundwater model of the study area is developed and used to predict the dewatering rate. The methodology mainly involves data collection, site hydrogeologic characterization and development of conceptual model, followed by construction and use of a groundwater model to predict the dewatering requirements of the mine site. The groundwater flow modeling is carried out using MODFLOW software and the dewatering simulations are carried out using MODFLOW Drain package. The drain cell configuration is determined by pit boundaries and invert elevations of drains corresponded to the bench elevations that will be achieved with respect to the mining schedule. In the transient model runs, monthly time steps were used. Using the outflow from in-pit drain cells, the
v
monthly dewatering rates are calculated. In order to assess the impacts of the hydraulic conductivity of the laterite on the pit inflow rates, simulations were carried out for different values of hydraulic conductivity of laterites. The predicted flow rate using the calibrated model is 107.54 L/s. A tenfold reduction in the hydraulic conductivity of laterite resulted in three fourths of decrease in the flow rate (24.42 L/s). Consequently, a wide range of flow rates for different hydraulic conductivity values of laterite was calculated. In order to confirm the hydraulic conductivity of laterites in the area, and to obtain a realistic dewatering rate, further pumping tests are needed.

Full textAbstract:
Natropalermoite, ideally Na2SrAl4(PO4)(4)(OH)(4), the Na-analogue of palermoite, is a new mineral from the Palermo No. 1 mine, Groton, New Hampshire, USA. Associated minerals are palermoite, eosphorite and quartz. Natropalermoite crystals are prismatic with striations parallel to the direction of elongation (the a axis) up to 200 mu m x 50 mu m x 45 mu m in size. The mineral is colourless, transparent with a white streak and vitreous lustre and is visually indistinguishable from palermoite. It is brittle with subconchoidal fracture and has a Mohs hardness of 5.5. Cleavage is perfect on {001}, fair on {100} and no parting was observed. The calculated density is 3.502 g cm(-3). Natropalermoite is biaxial (-), alpha = 1.624(1), ss = 1.641(1), gamma = 1.643(1) (589 nm), 2V(meas) = 43(4)degrees, 2V(calc) = 38 degrees. An electronmicroprobe analysis yielded an empirical formula (based on 20 O apfu) of (Na1.69Li0.31)(Sigma 2.00) (Sr0.95Mg0.04C a(0.02)Ba(0.01))(Sigma 1.02) (Al3.82Mn0.03Fe0.03)(Sigma 3.88) (P1.01O4)(4)(OH)(4). Natropalermoite is orthorhombic, space group Imcb, a = 11.4849(6), b = 16.2490(7), c = 7.2927(4) angstrom, V = 1360.95(17) A(3), Z = 4. Natropalermoite is isotypic with palermoite, but substitution of the larger Na for Li results in substantial increase of the b cell parameter. Four of the seven Na-O distances are longer than their equivalents in palermoite, resulting in a more regular 7-fold coordination polyhedron about Na. The eight strongest peaks in the calculated X-ray powder diffraction are [d(calc) (angstrom), I-rel%, (hkl)]: [3.128, 100, (321)], [4.907, 68, (121)], [3.327, 48, (022)], [4.689, 45, (220)], [3.078, 45, (202)], [2.453, 38, (242)], [2.636, 35, (411)], [2.174, 35, (422)].

Full textAbstract:
In this study, subsidence analyses were carried out for panels B14, B12, B10, B02, C12, C10, C08 of Ç<br>ayirhan Lignite Mine using in-situ subsidence measurements.
Using the measurements from stations, installed both parallel and perpendicular to panel-advance direction, subsidence profiles were plotted as a function of time and distance from panel center. Horizontal displacement and strain curves were also plotted and compared with subsidence profiles.
There are various methods used for subsidence prediction. In this study however, a subsidence model was developed based on empirical model obtained from nonlinear regression analysis. During the analyses SPSS (V.10.0) software was used and the unknown parameters associated with subsidence function were determined for the stations above B14 panel. Since it was too complicated to take all the affecting factors into consideration, only the parameters which could be estimated by statistical evaluation were taken into account during analyses.
One significant contribution of this study to subsidence subject was the comparison of the subsidence values measured during this investigation with the values predicted by some other empirical methods.
In this study, the structural damages to the pylons installed on ground surface above retreating longwall panels were also investigated by the use of previous studies. Slope as well as horizontal strain changes caused by ground movements
due to underground mining were determined.
Last but not least, it should be stated another significant contribution of this study to engineering was the collection of a significant database obtained from field measurements.

Full textAbstract:
The expenditures resulting from work accidents is increasing every year. Among the other work accidents, mine accidents result important loss of time, money and lives. From the point of view of mine accidents, studies about cost of mine accidents need some contributions. In this thesis, cost of mine accidents to worker, employer, and total economy of country will be analysed in the light of data from Ministry of Labour, Social Security and Social Insurance Institution, and Tü<br>rkiye Coal Enterprises. General Analysis is carried out within all industrial sectors, Mining sector, and Coal Mining sector. Detailed analysis is carried out within Western Lignite Company (GLi).
Occupational accidents have vital importance for the mines from legal, human and economic aspects. The goal of every mine should be to minimize occupational accidents. The top management of every mine should prove their commitments to the occupational health and safety policy to carry out this goal by means of preparing and implementing an accident preventing program.

Full textAbstract:
This thesis defends the idea that the mind is essentially computational, a position that has in recent decades come under attack by theories that focus on bodily action and that view the mind as a product of interaction with the world and not as a set of secluded processes in the brain. The most prominent of these is the contemporary criticism coming from enactivism, a theory that argues that cognition is born not from internal processes but from dynamic interactions between brain, body and world. The radical version of enactivism in particular seeks to reject the idea of representational content, a key part in the computational theory of mind. To this end I propose a Compatibilist Computational Theory of Mind. This compatibilist theory incorporates embodied and embedded elements of cognition and also supports a predictive theory of perception, while maintaining the core beliefs pertaining to brain-centric computationalism: That our cognition takes place in our brain, not in bonds between brain and world, and that cognition involves manipulation of mental representational content. While maintaining the position that a computational theory of mind is the best model we have for understanding how the mind works, this thesis also reviews the various flaws and problems that the position has had since its inception. Seeking to overcome these problems, as well as showing that computationalism is still perfectly compatible with contemporary action and prediction-based research in cognitive science, the thesis argues that by revising the theory in such a way that it can incorporate these new elements of cognition we arrive at a theory that is much stronger and more versatile than contemporary non-computational alternatives.

Full textAbstract:
This thesis compares philosophers Ken Wilber (Integralism) and Leonard Peikoff (Objectivism), who argue that Western philosophy is saturated with a fallacious mind/body dichotomy, which they trace historically and psychologically. Wilber’s and Peikoff’s agendas, worldviews and starting points are contrasted, specifically, Wilber’s holons, Kosmos model, the Big Three Value Spheres and Peikoff’s metaphysical axioms. Their definitions of consciousness are reviewed, along with their mutual epistemological emphasis on knowledge as contextual. Wilber makes mystical validity claims supported by stages of cognitive development. Discussed attributes of the mind/body dualism are: regression and repression; control versus chaos; hedonism, uniformity and authoritarianism; Subjectivism and Intrinsicism; Ego-agency versus Eco-communion. Both philosophers maintain that each partial strategy collapses into the dysfunctions of the opposite strategy. Their respective models of resolution through integration are presented in conclusion, particularly Wilber’s case for nondual Self-realization.

Full textAbstract:
In this thesis, studies associated with the stability analyses of the box-shaped dump-site culvert constructed in Tinaz Surface Mine of Turkish Coal Enterprises (TKi) are presented. In addition, stability conditions of other culvert alternatives are evaluated.
Existence of creeks in a surface mining area is a significant factor to be considered in selection of dump-site location. Since, the dumped overburden material on the valley acts as a barrier and behaves like a dam causing flood problem behind the dump-site. TKi engineers prevented the flood potential that might have occurred behind the dump-site by constructing a 480-meter long reinforced-concrete culvert on the downstream of Gevenez Creek Valley. However, considerable amount of deformations occurred in the first 100 meters of the culvert, as a result of overburden material being replaced on this structure.
In order to determine the failure mechanism associated with the culvert, a series of numerical modeling analyses were carried out utilizing back analysis technique. The validity of the numerical model was justified by convergence measurements and observations carried out inside the culvert as overburden material being replaced on the stable part of this structure. Finally, based on the numerical model developed, the stability of other culvert alternatives that could be used in future projects were evaluated considering different embankment conditions (positive projecting and negative projecting), bedding conditions (impermissible, ordinary, first-class and concrete cradle), culvert shapes (box and circular) and dumping conditions.

Full textAbstract:
Despite great technological advances in coronary artery bypass grafting (CABG) surgery, there is a high incidence of cardiac dysfunction and neurocognitive deficits in the postoperative period. Preventive measures are essential to reducing these adverse situations that are responsible for significant morbidity and impairment on life quality of these patients. Surgery and cardiopulmonary bypass (CPB) produces important changes in the immune system, directly involved in the incidence of these complications and is credible that anesthesia choice can it modified. We hypothezised that dexmedetomidine, an (α)-2-agonist, could the inflammatory response to CABG and CPB modified. In a prospective and randomized study, we intend to demonstrate the influence of dexmedetomidine (TIVA-DEX group), as a component of a conventional total intravenous anesthesia (TIVA-propofol+sufentanil) in patients undergoing CABG, with mini-CPB, on the behavior of this inflammatory response. The TIVA-DEX group received a continuous infusion of dexmedetomidine associated to a conventional venous anesthesia (continuous infusion of propofol+sufentanil). Intraoperative dosage of cytokines, such as interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-10 (IL-10), gamma interferon (INF-γ) and tumor necrosis factor (TNF-α) were performed, and also C-reactive protein (CRP), creatine phosphokinase (CPK), creatine phosphokinase-MB (CPK-MB), I troponin (cTnI), cortisol and glucose. The occurrence of lipid peroxidation, by the study of thiobarbituric acid reactive substances (TBARS) and the activity of delta-aminolevulinate dehydratase (δ-ALA-D) to oxidative stress verify were also avaliated. Dexmedetomidine induce a significative reduction of IL-1, IL-6, TNF-α and INF-γ, as compared to group that not receive dexmedetomidine. The levels of IL-10 were decreased in both groups along the time, at a similar pattern. Differences between groups on δ-ALA-D activity do not occur and TBARS was higher in TIVA-DEX group. We concluded that dexmedetomidine associated to TIVA was able to reduce plasma levels of proinflammatory cytokines IL-1, IL-6, TNF-α and INF-γ in patients submitted to CABG surgery under mini-CPB, as compared to a conventional TIVA. These results reinforce literature data about dexmedetomidine potentiality as an anti inflammatory agent.<br>Apesar dos grandes avanços tecnológicos nas cirurgias de revascularização miocárdica (CRM), ocorre uma grande incidência de disfunção cardíaca e déficit neurocognitivo no período pós-operatório. As medidas preventivas são essenciais para a redução destas situações adversas, responsáveis pelo comprometimento da qualidade de vida dos pacientes. A cirurgia e a circulação extra-corpórea (CEC) produzem alterações importantes no sistema imunológico, diretamente envolvidas na incidência das complicações e acredita-se que a escolha anestésica possa modificá-las. Em estudo prospectivo e randomizado, pretendemos demonstrar a influência da dexmedetomidina (grupo AIVT-DEX), um anestésico (α)-2-agonista, associado à anestesia intravenosa total (AIVT) no comportamento da resposta inflamatória em pacientes submetidos à CRM, sob mini-circulação extracorpórea (mini-CEC). O grupo AIVT-DEX recebeu infusão contínua de dexmedetomidina associado à técnica de AIVT convencional e o outro grupo foi submetido à AIVT convencional (infusão contínua de propofol e sufentanil). Os grupos foram comparados pela dosagem plasmática trans-operatória de citocinas, como a interleucina-1(IL-1), a interleucina-6 (IL-6), a interleucina-10 (IL-10), o interferon gama (INF-γ) e o fator de necrose tumoral alfa (TNF-α), bem como a proteína C reativa (PCR), creatinofosfoquinase (CPK), creatinofosfoquinase miocárdio específica (CPK-MB), troponina I (cTnI), cortisol e glicose. A peroxidação lipídica foi avaliada pelo estudo das substâncias reativas ao ácido tiobarbitúrico (TBARS) e a presença de estresse oxidativo pela atividade da enzima delta-aminolevulinato desidratase (δ-ALA-D). O uso da dexmedetomidina induziu redução significativa de IL-1, IL-6, TNF-α e INF-γ se comparado ao grupo sem dexmedetomidina. Houve redução progressiva dos níveis de IL-10 ao longo do tempo, de forma semelhante entre os grupos. Não houve diferença entre os grupos para a atividade da enzima δ-ALA-D e os níveis de TBARS foram maiores no grupo AIVT-DEX. Concluímos que a dexmedetomidina associada à AIVT convencional foi capaz de reduzir os níveis plasmáticos das citocinas pró-inflamatórias IL-1, IL-6, TNF-α e INF-γ em pacientes submetidos à CRM sob mini-CEC, se comparados aos pacientes que receberam apenas a AIVT convencional. Estes resultados reforçam os dados da literatura quanto à potencialidade da dexmedetomidina como agente modulador da resposta inflamatória no período trans- operatório.

Estas análises são simplificadas, pois fornecem valores de FS sem considerar a variabilidade intrínseca dos solos e rochas.
Desprezar as incertezas dos parâmetros geotécnicos pode levar a resultados pouco confiáveis sobre a segurança de taludes. Análises fundamentadas em conceitos estatísticos, chamadas probabilísticas, passam ser mais frequentes na geotecnia por permitirem considerar efeitos da variabilidade inerente aos materiais. Estas análises incorporam elementos estatísticos que possibilitam tratar FS como uma função e estudar suas propriedades. Como resultados finais, os métodos probabilísticos fornecem o índice de confiabilidade (beta) e a probabilidade de ruptura (Pr) da estrutura averiguada. Este trabalho aplica análises determinísticas e probabilísticas de um talude de 200m de altura da Mina do Cauê, Itabira, MG. A estabilidade do talude foi analisada por cinco métodos determinísticos usuais e três probabilísticos (FOSM, EP e MC). Os resultados indicam que a fixação da superfície crítica de ruptura fornece, em geral, valores de beta e Pr semelhantes aos obtidos quando a superfície pode variar livremente. Com a superfície crítica fixa
observou-se, também, que os resultados de beta e Pr do talude variam significativamente com o método de equilíbrio limite adotado. Após comparação dos resultados, pode-se recomendar o uso de análises probabilísticas FOSM com base no método de Morgenstern-Price em análises semelhantes ao caso estudado.<br>In current geotechnical practice, slope stability assessments are usually carried out only based on deterministic methods, obtaining a value of Safety Factor (FS). These analyses are simplified because the FS values do not consider the natural variability of soils and rocks. Disregarding the uncertainties inherent to geotechnical parameters may lead to unreliable results of slope safety. Probabilistic analyses, based on statistical concepts, have become more frequent in geotechnical practice, as they allow incorporating the materials intrinsic variability. These analyses are based on statistical elements that allow treating the FS as a function and studying its properties. The probabilistic methods indicate the reliability index (beta) and the probability of failure (Pr) of the verified geotechnical structure. This work presents deterministic and probabilistic analyses of a 200m high slope at the Cauê Mine, located in Itabira, Minas Gerais, Brazil, with basis on five usual deterministic methods and three probabilistic techniques (FOSM, Point Estimates and Monte Carlo). The results indicate that fixing the critical deterministic surface generally gives values of beta and Pr similar to those achieved when the surface is free to vary. It was also concluded that, with a fixed
critical surface, beta and Pr results change significantly, when different Limit Equilibrium methods are adopted. It is recommended to use probabilistic FOSM analysis with Morgenstern and Price stability method in analyses similar to the one presented herein.

Full textAbstract:
Almgren-Pitts min-max theory considers the space of integral currents on a manifold with the associated mass functional. Minimal hypersurfaces arise as the critical points of the mass functional, and so can be constructed using min-max techniques applied to certain families of integral currents. A particular set of families is the Gromov-Guth p-sweepouts. The min-max masses associated with these families are the p-widths. This thesis calculates several p-widths for p <= 13 in the case of the round three-sphere by explicit construction of p-sweepouts and Lusternik-Schnirelmann topological arguments. It follows from recent developments in min-max theory that there is a minimal surface with genus > 1, index <= 9 and area equal to the 9-width.

Quantifying the geometries of evaporite deposits at a <1 km scale is critical in our understanding of similar ancient depositional systems, but is challenging given evaporite mineral dissolution at surface conditions. Two high-resolution stratigraphic studies in mines provide insight into the geometries, dimensions, and spatial distributions of sedimentary bodies in 3-D at a <1-km scale in evaporites. A field mapping study was conducted in Brightling (Purbeck Group) and Boulby (Zechstein Group) mines, in southeast and northeast England, respectively. This is integrated with XRD, petrography, and δ13C and δ18O isotope analyses. The evolution and conditions of sedimentation during the Tithonian in the Weald Basin is also evaluated. A newly defined megasequence boundary at the base of the Purbeck Group is suggested to mark the onset of rifting of the Bay of Biscay and to the north of the Charlie-Gibbs Fracture Zone, which implies an earlier rifting phase than previously proposed. Basal Purbeck lateral facies changes are influenced by the position in the Weald Basin, normal fault systems, and relative sea level changes. In Brightling Mine, the basal Purbeck exhibits carbonate-evaporite shoaling upward cycles, likely controlled by localized high-frequency relative sea level changes and/or sabkha hydrology. The dynamic process of evaporite deposition led to subtle stratigraphic heterogeneities and changes in bed thicknesses, but largely continuous lateral bedding. Boulby Mine offers a unique opportunity to study early deformation structures in ancient polyhalite that formed in playa conditions. The controlling mechanism that formed these syndepositional polyhalite tepees is attributed to soft sediment deformation via polyhalite dewatering coupled with penecontemporaneous precipitation of halite during fluid escape. This study offers new insight into the types of heterogeneity observed in ancient evaporites formed in marginal playa and sabkha environments at a < 1 km-scale, which can include a variety of compositions and morphologies at a range of scales.

Orthodontists have been reusing mini-implants that fail after installation or that will be
inserted in a new place due to mechanic needs in order to optimize clinical time. The
aim of this study was to simulate the reuse of mini-implants up to three times and
evaluate their potential weakness. We used 48 screws (Morelli, Sorocaba, Brazil), which
were divided into four groups: C= Control, G1 = one reuse, G2 = two reuse, G3 = three
reuse. In order to simulate inserts in patients mouths, we used pig iliac bone. After we
insert screws on bone specimen, we removed, cleaned, and sterilized them by
autoclaving. The guide at the machine we used allowed us to standardize installations.
After all groups were submitted to their reuse periods, mini-implants were submitted to
fracture, and the strongest force necessary to break them was measured by a digital
axial torquemeter. We used bovine tibia specimens for fracture, because of its greater
bone cortical and bone density. We used One Way ANOVA (Bonferroni post-hoc) to
compare means of each group. Results showed differences statistically significant
between G3 and the other groups. All mini-implants needed strength higher than
recommended by the literature to be inserted into patients, even though we found
differences in fracture resistance between groups.<br>Na busca por não perder tempo clínico, ortodontistas vêm reutilizando mini-implantes

foram utilizados 48 parafusos (Morelli Sorocaba-SP, Brasil), os quais foram divididos
em quatro grupos: C = Controle, G1 = uma reutilização, G2 = duas reutilizações e G3 =
três reutilizações. Para simular, laboratorialmente, as instalações em boca nos
pacientes, foi utilizado osso ilíaco suíno. Após serem inseridos no espécime de osso, os
parafusos foram removidos, limpos e esterilizados em autoclave. Com um guia presente
na máquina utilizada foi possível padronizar as instalações. Após todos os grupos
passarem pelos ciclos de reutilização correspondentes, os mini-implantes foram
submetidos à fratura, e a força máxima necessária para a quebra foi medida através de
um torquímetro digital axial. Para a fratura, foram utilizados espécimes de tíbia bovina,
por possuir maior densidade óssea e espessura de cortical. Os valores médios dos
grupos foram analisados pela ANOVA de 1 fator com post-hoc em Bonferroni. Foram
encontradas diferenças estatisticamente significativas entre o grupo G3 e os demais
grupos. Mesmo com as diferenças na resistência à fratura entre os grupos, todos
necessitaram de forças superiores às recomendadas para instalação em pacientes.

Full textAbstract:
This thesis analyses the method, purpose, and results of Aristotle's treatment of a select number of Presocratic and Platonic theses about the soul within the context of De Anima 1. Contrary to a prevalent interpretation of De Anima 1 which sees Aristotle's treatment of his predecessors' psychological views as dialectical, I argue that Aristotle treats his predecessors as having offered potentially viable hypotheses about the nature of the soul, and that these hypotheses are treated as attempts to explain the soul's basic powers. I further show that, in order to test the explanatory limits of these theories, Aristotle uses a version of the scientific method of inquiry advertised in the Prior and Posterior Analytics, which consists in setting out the basic psychological phenomena which psychology should explain, and then testing the extent to which his predecessors' definitions of the soul are able to accomplish this task. This thesis argues that, by demonstrating where his predecessors' first principles fall short, Aristotle is able to make theoretical progress towards establishing his own 'hylomorphic' first principle of soul, that soul is the 'first fulfilment of a natural instrumental body', and towards the idea that soul operates in the body of living beings as a formal, final, and efficient cause.

This thesis consists of a mathematical model, autopilot and guidance design of a mini ROV (Remotely Operated Underwater Vehicle) and investigates the effects of environmental forces (ocean currents etc.) on the guidance algorithms. First of all, a non-linear 6 degrees-of-freedom (DOF) mathematical model is obtained. This model includes hydrodynamics forces and moments. There is no exact calculation method for hydrodynamic coefficients<br>however strip theory and results of computational fluid dynamics (CFD) analysis are used to calculate their approximate values. Linear mathematical model is obtained by linearization at trim points and it is used when designing surge speed, heading and depth controller. Guidance is examined by two methods such as way point guidance by line-of-sight (LOS) and way point guidance based on optimal control. Moreover, an online obstacle avoidance algorithm is developed. This thesis ends with the subject of navigation of the vehicle under GPS-like measurements and magnetic sensors measurements.

A maioria das fruteiras nativas pertencem a família Myrtaceae, que apresentam como principal potencialidade a comercialização seus frutos. Apesar da grande aceitação dos frutos destas fruteiras, ainda é necessário a criação de pomares comerciais, pois prevalece-se o extrativismo. Para iniciar qualquer pomar, o primeiro ponto está na escolha da planta matriz, devendo esta apresentar características de superioridade quando comparadas aos outros genótipos. A partir disso, deve-se proceder na escolha do método que possibilite produzir quantidade de mudas satisfatória e de preferência sem perder as características da planta mãe. Para isso adota-se técnicas assexuadas, com opção para enxertia, estaquia e alporquia. Estas técnicas quando testadas com fruteiras nativas, mostraram-se limitantes em diversos aspectos, devendo-se testar outra que poderá ser recomendada para uso, principalmente naquelas de maior potencialidade como jabuticabeiras, pitangueiras, sete capoteiro e araçazeiro amarelo. O objetivo deste trabalho foi testar o uso da propagação assexuada por mini-estaquia nestas fruteiras, de acordo com época de coleta, comprimento da mini-estaca e concentração de AIB, bem como, relacionar tais resultados de rizogênese com triptofano extraído em determinados períodos. O trabalho foi realizado na Universidade Tecnológica Federal do Paraná - Câmpus Dois Vizinhos. As coletas foram realizadas bimestralmente. Foram preparadas mini-estacas com 6 ou 8 cm, com par de folhas reduzido a 25% do tamanho original. As mini-estacas tiveram sua base imersa em solução líquida de ácido indol-butírico (AIB), nas concentrações de 0, 3000 e 6000 mg L-1 e em seguida foram colocadas em tubetes contendo substrato comercial. O delineamento experimental foi inteiramente casualizado com fatorial 2 x 3 x 6 (comprimento de estaca x concentração de AIB x época do ano), com quatro repetições, sendo a unidade experimental variou de acordo com a quantidade de brotações obtidas em tais períodos. Aos 120 dias da implantação de cada coleta foram avaliados o enraizamento e calogênese (%), número médio de raízes por mini-estaca e comprimento médio das raízes. Após 60 dias destas análises avaliou-se a sobrevivência das mini-estacas enraizadas pós-plantio. Também avaliou-se a produção de mini-estacas de cada tamanho em cada época do ano. Ao final do experimento avaliou-se o percentual de sobrevivência das mudas matrizes. Para análise de triptofano utilizou-se materiais de ramos, folhas e ramos com folhas, retirados dos materiais utilizados para produção de mini-estacas. Recomenda-se para jabuticabeira híbrida o uso de mini-estacas com oito centímetros, tratadas com 6000 mg L-1 de AIB e coletadas em junho. Para jabuticabeira de cabinho e araçazeiro o período de coleta para propagação por mini-estaquia destas deve ser em agosto, independente da concentração de AIB e comprimento da mini-estaca. Com a jabuticabeira sabará e sete capoteiro é importante para obtenção de resultados mais satisfatórios a coleta sendo realizada tanto em outubro quanto em dezembro, com mesma independência dos outros níveis testados nos outros fatores. Contudo, para sete capoteiro deve-se testar outras técnicas para aumentar a eficiência da propagação. E com pitangueira recomenda-se coletar em junho, porém nas de 6 cm aplicação de 3000 mg L-1 de AIB e de 8 cm com 6000 mg L-1 de AIB.<br>The most native fruit trees are belonging to Myrtaceae family, which it have as main marketing potential their fruit. Despite the wide acceptance of the fruits of these native fruit cultura, the establishment of commercial orchards is still necessary, because if it prevails extraction in the forest. To start the cultivo in the orchard, the first point is on the mother plant choice, which should provide superior characteristics when compared to other genotypes. Then, it is necessary to choose the method to can produce satisfactory amount of seedlings and preferably without it to lose the mother plant characteristics. For this, it adopts the asexual thechniques, with option for grafting, cuttings and air layering. These techniques when tested with native fruits tree, it proved limiting in theses results, with this, it should to test other it to recommend its use, especially, those fruit native of higher potential as jabuticaba tree, pitanga tree, sete capote tree and araça amarelo tree. The aim of this study was to test the use of asexual propagation through mini-cuttings in these native fruit trees, according to the time of collection, the mini-cutting length and concentration of IBA, as well as, it to relate the results of rooting with tryptophan extracted at certain times. The work was carried out at Universidade Tecnológica Federal do Paraná – Câmpus Dois Vizinhos, Brazil. The samples were collected each two months. The mini-cutting were prepared with 6 or 8 cm, with a pair of leaves reduced to 25% of the original size. The mini-cuttings had their base immersed in liquid solution of indole-butyric acid (IBA) in the concentrations of 0, 3000 and 6000 mg L-1 and then were placed in tubes containing commercial substrate. The experimental design was completely randomized with factorial 2 x 3 x 6 (mini-cutting length x IBA concentration x time of collection), with four replications, it being each plot varied according to the amount of shoots obtained by period time. After 120 days, the rooting and callus formation (%), average number of roots per mini-cutting and the average length of the roots were evaluated. After 60 days of these evaluations, the survival of mini-cuttings rooted after transplant was evaluated. It was evaluated also the production of mini-cuttings of each size in each period time. At the end of the experiment it was evaluated the percentage of survival of mother plantlets. For analysis of tryptophan was used materials branches, leaves and twigs with leaves, taken from the materials used for the production of mini-cutting. It was recommended for hybrid jabuticaba tree the use mini-cutting with eight cm, treated with 6000 mg L-1 of IBA and collected in June. For jabuticaba tree of cabinho and araça amarelo tree the period for propagation by mini-cuttings should be in August, regardless of IBA concentration and length of the mini-cutting. In the jabuticaba tree sabara and sete capote tree is important to obtain more satisfactory results realized the collect in October or December, with the same independence of other levels tested in other factors. However, for sete capote tree should test other techniques to increase the efficiency of propagation. And with pitanga tree recommended to the collection in June, but with 6cm the application of 3000 mg L-1 of IBA and 8 cm with 6000 mg L-1 of IBA.

Full textAbstract:
Tomatoes are among the most cultivated and used vegetables in the world. They are very succeptible to post harvest losses due to high perishability, therefore the use of postharvest treatments may contribute to conservation of this fruit, however the treatments might affect significantly physico-chemical, sensory and nutritional characteristics of tomatoes. Given the perishability of tomato and the economic importance of small tomato fruits, the purpose of the present study was to determine the effect of gamma radiation, carnauba coating and 1-MCP treatments on tomato fruit quality during storage. The study may be divided into two parts. In the first, mini tomatoes cv. Sweet Grape were harvested at breaker stage, divided into 4 grous and treated with gamma radiation (0.6 kGy), carnauba coating (1 L 1000 kg-1) and 1-MCP (500 nL L-1) and then stored at 25±2°C for 30 days with a control group of tomatoes. In the seconnd part, tomatoes harvested at light-red stage were submitted to the same treatments and storage period. Every 6 days tomatoes were evaluated for color modifications, fruit firmness, souble and total pectin (only for light-red tomatoes), mass loss, titratable acidity (TA), soluble solids (SS), SS/TA ratio, carotenoids profile, formation of lycopene isomers, total phenolic compounds, ascorbic acid and antioxidant capacity. For tomatoes harvested at breaker stage and submitted to the treatments the results showed mass loss was delaying mainly by carnauba wax, and to a lesser extend by 1-MCP. Fruit firmness were better retained for 1-MCP treated fruits and carnauba treatment showed a transient effect in preserving fruit firmness. SS/TA of tomatoes treated with gamma radiation and carnauba presented no differences from control values, and were lower with the application of 1-MCP. Color was negatively affected by 1-MCP and earlier changed (6th day) when gamma radiation was applied. In relation to bioactive compounds of tomatoes harvest at breaker stage, results indicated gamma radiation and 1-MCP decreased the final content of lycopene and produced more (Z)-isomers of lycopene. Gamma radiation also induced a decreased in ?-carotene and an increased in phenolic compounds by the end of storage period. 1-MCP treatment promoted a slow down increase in ascorbic acid content during storage. Antioxidant capacity of the hydrophilic fraction was not dramatically affected by treatments and the lipophilic fraction was lower, especially for 1-MCP fruits. In addition, contents of ?-carotene, lycopene, (Z)-isomers of lycopene, ascorbic acid and antioxidant capacity increased during the period of storage while contents of lutein and phenolic compounds tended to decrease. Regarding tomatoes harvest at light-red stage, the most effective treatments for delaying fruit firmness and mass loss was carnauba and 1-MCP, while gamma radiation was the treatment with higher mass loss and the less fruit firmness, which could be associated with the higher solubilization of pectins promoted by radiation treatment. Color (L* and Hue) was mainly affected by 1-MCP treatment which delayed color development, however, by the end of storage, the values were not different from the other treatments. SS/TA ratio was lower for fruits treated with 1-MCP and TA was not so dramatically affected by treatments. Furthermore, mini tomatoes harvested at light-red stage, demonstrated irradiation induced changes in the final content of lycopene, increasing it, and formed less (13Z)-lycopene, while 1-MCP and carnauba coating slow down the increase in lycopene and slown down the decrease of ascorbic acid and phenolic compounds. Antioxidant capacity of lipophilic fraction was not affected by treatments and the hydrophilic fraction was lower for irradiated fruits only on day 0 as well as phenolic compounds. In the other days, no differences among treatments were observed for hydrophilic antioxidant capacity. Considering the results, the best combination of SS and TA and fruit preservation for mini tomatoes harvest at breaker stage was promoted by carnauba coating, which seems to be the treatment that causes fewer changes in bioactive compounds of breaker tomatoes. However, when mini tomatoes were harvested at light-red stage, SS/TA ratio and color were better and, to preserve the quality of these fruits, besides carnauba coating, 1-MCP also could be indicated<br>Os tomates estão dentre as hortaliças mais cultivadas e consumidas no mundo, porém os frutos do tomateiro são muito sucetíveis a perdas após a colheita devido a alta perecibilidade, por isso, o uso de tratamentos pós-colheita pode contribuir para a conservação dos frutos. Entretanto, o uso destes tratamentos pode afetar significativamente características físico-químicas, sensorias e nutricionais dos tomates. Dada a perecibilidade e a importância econômica dos mini tomates, o objetivo deste estudo foi determinar o efeito da radiação gama, revestimento à base de cera de carnaúba e 1-metilciclopropeno (1-MCP) na qualidade do tomate durante o armazenamento. O estudo pode ser dividido em duas partes. Na primeira, mini tomates cv. Sweet grape colhidos no estádio de maturação breaker foram divididos em quarto grupos e tratados com radiação gama (0.6 kGy), cera de carnaúba (1 L 1000 kg-1) e 1-MCP (500 nL L-1) e então armazenados a 25±2°C por 30 dias, juntamente com um grupo de frutos controle. Na segunda parte, tomates colhidos no estádio de maturação vermelho-claro foram submetidos aos mesmos tratamentos e período de armazenamento. A cada seis dias os frutos foram avaliados para modificações nas características físico-químicas: coloração, firmeza, pectina solúvel e total (somente para os frutos vermelho-claro), perda de massa, acidez titulável (AT), sólidos solúveis (SS), relação SS/AT; e compostos bioativos: perfil de carotenoides, formação de isômeros de licopeno, compostos fenólicos totais, ácido ascórbico, e capacidade antioxidante. Para os tomates colhidos no estádio breaker, os resultados mostraram que a perda de massa foi retardada, principalmente pelo uso de cera de carnauba e de 1-MCP, este último em menor proporção. A firmeza dos frutos foi melhor retida para os frutos tratados com 1-MCP e, a cobertura com carnauba mostrou um efeito transitório em preservar a firmeza dos frutos. A relação SS/AT dos frutos irradiados e cobertos com carnauba não apresentaram diferenças dos valores do controle, mas foram menores com a aplicação de 1-MCP. A coloração foi negativamente afetada pelo uso do 1-MCP e precocemente modificada (no 6° dia) quando a radiação gama foi aplicada. Em relação aos compostos bioativos destes mesmos frutos, os resultados indicaram que a radiação gama e o 1-MCP diminuiram o conteúdo final de licopeno e produziram mais (Z)-isômeros de licopeno nos frutos. A radiação gama também induziu a diminuição de ?-caroteno e o aumento dos compostos fenólicos no final do período de armazenamento. A aplicação de 1-MCP promoveu desaceleração no aumento do conteúdo de ácido ascórbico durante o armazenamento. A capacidade antioxidante da fração hidrofílica não foi muito afetada pelos tratamentos e, a fração lipofílica foi menor para os frutos tratados com 1-MCP. Além disso, os teores de ?-caroteno, licopeno, (Z)-isômeros de licopeno, ácido ascórbico e capacidade antioxidante aumentaram durante o armazenamento, enquanto que, o teor de luteína e compostos fenólicos tenderam a diminuir. A respeito dos tomatates colhidos no estádio de maturação vermelho claro, os tratamentos mais efetivos para retardas a perda demassa e a firmeza foram a cobertura de carnauba e 1-MCP, enquanto o tratamento com radiação gama apresentou a maior perda de massa e de firmeza de frutos, o que pode ser associado a maior solubilização de pectinas promovida pela radiação gama. A cor (L* e Hue) foi principalmente afetada pelo tratamento com 1-MCP, que retardou o desenvolvimento da mesma, porém no final do período de armazenamento, os valores não diferiram dos outros tratamentos. A relação SS/AT foi menor para os frutos tratados com 1-MCP e a AT não foi muito afetada pelos tratamentos. Além disso, mini tomates colhidos no estádio vermelho-claro demosntraram que a irradiação induziu modificações no teor final de licopeno, aumentando-o e houve menor formação de (13Z)-licopeno, enquanto que 1-MCP e carnauba desaceleraram o aumento no teor de licopeno e desaceleraram a diminuição de ácido ascórbico e compostos fenólicos. A capacidade antioxidante da fração lipofílica não foi afetada pelos tratamentos e a fração hidrofílica foi menor para os tomates irradiados somente no dia 0, assim como para compostos fenólicos. Nos demais dias não houve diferenças entre os tratamentos. Considerando os resultados, a melhor combinação de SS/AT e preservação de mini tomates colhidos no estádio breaker foi promovida pela cobertura de carnaúba, a qual pareceu ser o tratamento que causou menores mudanças nos compostos bioativos dos tomates beaker. Entretanto, quando os mini tomates são colhidos no estádio vermelho-claro, SS/AT e coloração são melhor desenvolvidas e, para preservar a qualidade destes frutos, além da cera de carnaúba, o 1-MCP também pode ser indicado

Full textAbstract:
The award-winning Norwegian novelist Karl Ove Knausgård achieved great success with his latest book, Min kamp. Both commercially and critically, the novel was praised for its seemingly successful attempt to transcend the boundary between fiction and real life. Focusing on the auto-fictional narrator’s struggle to balance his daily life with his ever so demanding aesthetic ambitions, the novel gives high-detail descriptions of the most basic day-to-day chores, intimately mixed with philosophical reflections on topics such as painting, literature and postmodern civilisation. This essay proposes an alternative perspective on the realism of the novel. Instead of relying on a correspondence theoretical view, which highlights the level of correspondence of a particular representation with reality, I seek, inspired by Martin Heidegger’s thoughts on works of art, to trace a poetics which sees the verity in a work of art as the ”unconcealment” of the world, or the coming-to-being of objects. The function of art in relation to reality is to ”open up” the conventionally understood world and offer a perspective situated between an intellect-based outlook on the world and an intuitive and subconscious one. In order to carefully analyse the formal manifestation of the poetics in question, I turn to the notion of heteromediality, which proves fruitful in distinguishing, in the verbal text itself, certain formal traits usually associated with other media. I suggest that when found in the text, these traits function as a way of stressing the becoming of objects, rather than primarily their mere existence.

Le problème de Minmax en variables continues ou en variables entières a toujours suscité un intérêt croissant d'une part, parce que son champs d'application est vaste. Que ce soit dans le domaine des mathématiques, l'allocation de ressource, l'économie, l'aéronautique et même des jeux. D'autres part, parce que les problèmes traités sont classés en théorie de la complexité comme NP-difficile même quand il s'agit d'un problème de Minmax en variables 0-1 sans contrainte et avec seulement deux objectifs. Cette thèse contribue à l'étude des problèmes en variables bivalentes. Elle propose la résolution exacte et approchée des problèmes de Minmax ou Maxmin en variables 0-1 qui consistent à minimiser un objectif exprimé sous la forme d'un minimum ou maximum de plusieurs fonctions linéaires et soumis à un ensemble de contraintes.

Full textAbstract:
Mini unmanned Air Vehicles (UAV) have high significance among other UAV'<br>s, in different categories, due to their ease of production, flexibility of maintenance,
decrease in weight due to the elimination of landing gear system and simplicity of use. They are usually built to meet '<br>hand launching'<br>and '<br>belly landing'<br>criteria in order to have easy flight and easy landing features. Due to the hand take-off and belly landing features there is no need to have a runway and this feature is a very
significant advantage in operational use. In an operation, belly landing mini UAV'<br>s may encounter tough landing areas like gravel, concrete or hard soil. Such landing areas may create landing loads which
are impulsive in character. The effect of the landing loads on the airframe of the mini unmanned air vehicle must be completely understood and the mini UAV be designed accordingly in order not to damage the mini UAV during belly landing. Typical impact speeds during belly landing is relatively low (<<br>10 m/s) and in general belly landing phenomenon can be treated as low velocity impact.
The purpose of this study is to analyze the impact loads on the composite substructures of a mini UAV due to the belly landing. '<br>Gü<br>ventü<br>rk'<br>Mini UAV which is designed and built in METU Aerospace Engineering Department, is used as the
analysis platform. This study is limited to the calculation of stresses and deformation that is caused by the low velocity impact forces encountered during belly landing.
The main purpose of this work is to help the designer in making design decisions for a mini UAV that is tolerable to low velocity impact loads. Initial part of the thesis includes analytical treatment of low velocity impact
phenomenon. In the simplified analytical approach the loading is assumed as quasistatic
and comparisons of such a simplified method of analysis is made with explicit finite element solutions on isotropic and composite plate structures to investigate the
applicability of simplified analytical method of analysis.
Belly landing analyses of the mini UAV are done by MSC.Dytran, which is an explicit finite element solver. Model building and post processing are done via MSC.Patran.
Stress and deformation response of the mini UAV is investigated by performing low velocity impact analysis using sub-structure built-up approach.

Full textAbstract:
Dealing with the problem between user related knowledge and design, the present thesis underlines the guiding role of designer&rsquo<br>s user concept as a concept in problem structuring, by framing his/her understanding about user and influencing knowledge use and solution generation. Considering limitations of prevailing user concept in the architectural design studio, underlying problems are detected with reference to knowledge and design contexts, which have critical influence on the formation of user concept, particularly on its capacity to cover qualities of user and its relation with design. Defined narrow content of knowledge context and the detachment between design and knowledge contexts constitute the problematic basis of limited user concept and indicate a need for a shift in student&rsquo<br>s user understanding. The thesis aims to provide a conceptual framework to define required change referring underlined contexts. The broadening of knowledge context is defined addressing unifying perspective of Universal Design, with its emphasis on diversity, user experience, and knowing user by experience. With reference to the notion of designerly ways of knowing, required constructive relation between knowledge and design contexts is reconceptualized as designerly way of knowing user and defined as user related knowledge generation as part of problem structuring and design concept generation through this knowledge base. The potentials of proposed framework are exemplified by an architectural design studio experience. The analysis shows that when student&rsquo<br>s user learning is organized within student&rsquo<br>s actual user investigation as part of problem structuring, it is possible for students to acquire needs and expectations of diverse users and translate them to solutions from user perspective generating user related design concepts. Therefore, proposed conceptual base promises to improve user concept of student not only to involve experiences of diverse users, but also to be designerly.

This study has the objective of investigating the performance of adults and seniors in terms of working memory skills and at the Mini-Exam of Mental State, verifying how these skills relate to each other, to the age and to the scholarship level. The sample was composed by 34 people, with ages among 37 and 83 years-old, Brazilians, Portuguese speakers, literate and without any evident and referred neurological and/or
cognitive alterations and it was shared into four groups according to the age group. The adults and seniors performance at the working memory assessments was checked
through the repetition of non-words task to assess specifically the phonological memory and the repetition of a sequence of digits to assess the central executive and
the phonological memory, according to Baddeley and Hitch s proposal (1974 apud GATHERCOLE & BADDELEY, 1993). The Mini-Mental State Examination, Folstein and McHugh s proposal (1975), was used to assess the orientation, immediate memory, attention, calculation, mandate, language, reading and constructive praxis. In order to analyze the co-relation among the evaluations it was used the non parametric test, the Sperarman s Correlation Coefficient, from which it was identified: 1) the younger people had a better performance at the three tasks applied when compared with the older ones; 2) there was a significant correlation between the repetition of non-words and repetition of a sequence of digits tasks; 3) the Mini-Mental State Examination has a small
correlation with the memory working tasks; 4) it was observed significant correlation of age and scholarship with the tasks of repetition of non-word, repetition of a sequence of digit and Mini-Mental State Examination. Comparing the four groups, it was verified that the rightness average at the three assessmests diminished as much as the age group
increased. It was observed that the rightness averages at the working memory and Mini- Mental State Examination tasks increased according to the scholarship level. It concluded that older people with low scholarship level, considered as a group not individually, present smaller performance at the working memory and Mini-Mental State Examination tasks than younger people and with higher scholarship level<br>Este estudo teve por objetivo investigar o desempenho de adultos e idosos em habilidades de memória de trabalho e no Mini-Exame do Estado Mental, verificando como estas habilidades relacionam-se entre si, com a faixa etária e com o nível de escolaridade. A amostra foi formada por 34 sujeitos, com idades entre 37 e 83 anos, brasileiros, falantes do português, alfabetizados e sem alterações neurológicas e/ou
cognitivas evidentes e referidas, e foi dividida em quatro grupos conforme a faixa etária. O desempenho dos adultos e idosos nas avaliações de memória de trabalho foi verificado através da tarefa de repetição de não-palavras para avaliar especificamente a memória fonológica, e da tarefa de repetição de seqüência de dígitos para avaliar o executivo central e a memória fonológica, segundo a proposta de Baddeley & Hitch (1974 apud GATHERCOLE & BADDELEY, 1993). O Mini-Exame do Estado Mental, proposto por Folstein & McHugh (1975), foi utilizado para avaliar orientação, memória imediata, atenção, cálculo, evocação, linguagem, leitura e praxia construtiva. Para analisar a correlação entre as medidas foi utilizado o teste não-paramétrico Coeficiente
de Correlação de Spearman, através dos quais verificou-se que: 1) os sujeitos mais jovens desempenharam melhor as três tarefas aplicadas quando comparados com os sujeitos mais velhos; 2) houve correlação significativa entre as tarefas de repetição de não-palavras e repetição de seqüência de dígitos; 3) o Mini-Exame do Estado Mental apresentou fraca correlação com as tarefas de memória de trabalho; 4) houve
correlação significativa entre idade e escolaridade com as tarefas de repetição de nãopalavras, repetição de seqüência de dígitos e com o Mini-Exame do Estado Mental. Na
comparação entre os quatro grupos, verificou-se que as médias de acertos nas três avaliações aplicadas diminuíram conforme a faixa etária aumentou. Comparando-se as médias de acertos nas tarefas de memória de trabalho e no Mini-Exame do Estado Mental de acordo com o grau de escolaridade, observou-se que as médias nas tarefas
analisadas aumentaram em função do grau de escolaridade. Concluiu-se que sujeitos mais velhos e com baixa escolaridade, quando considerados como um grupo e não
individualmente, apresentam desempenho inferior nas tarefas de memória de trabalho e no Mini-Exame do Estado Mental do que os sujeitos mais jovens e com níveis mais altos de escolaridade

Full textAbstract:
The present thesis belongs to the research area disability research and deal with specific aspects of cognition in individuals with Usher syndrome type 1 and 2. The subject has been investigated and is discussed within an interdisciplinary framework, though the theories applied and described are derived from the area of cognitive psychology. Usher syndrome is a rare genetic condition causing a combination of visual and hearing impairment: deafblindness. There is a congenital hearing loss that is profound in type 1 and moderate to severe in type 2. During mid-childhood symptoms of visual impairment, e.g. light sensitivity, emerge and a progressive loss of visual field follows as a result of the genetically caused eye disease Retinitis Pigmentosa. The syndrome has previously been well described with respect to the genetical and medical aspects, but there has been very little research with a cognitive perspective on the population. Studies 1 and 2 in the present thesis focused on children with Usher syndrome type 1 with cochlear implants and investigated phonological skills, lexical access, working memory and reading skill in the group. Studies 3 & 4 investigated the same cognitive abilities and theory of mind in adults with Usher syndrome type 2. In study 4 the performance on theory of mind in the adults with Usher syndrome type 2 was also compared to that of another group with genetically caused deafblindness: individuals with Alström syndrome. The results were that both the children and adults with Usher syndrome had significantly poorer phonological processing than the control groups with normal hearing. There was a large variation on performance on lexical access, especially in the group of children, however several individuals performed at the same level as the control group. Reading skill was found to be at level with the control groups’. There was also great variation in performance on ToM, however the majority of individuals performed similar to the control group with normal hearing and vision. The present project has resulted in some new knowledge on cognitive performance in individuals with Usher syndrome type 1 and type 2. Performance in the participants with Usher syndrome can to a large extent can be understood by application of the models developed in previous research on populations with hearing impairment or deafness for understanding the impact of hearing with a hearing aid or cochlear implant. However, individuals with Usher syndrome experience additional difficulties in accessing information due to the progressive visual loss and the impact this has on performance is still largely unknown. Hence, the present project would recommend that interventions and support would be designed specifically to each individuals’ needs, with consideration of both the visual impairment and the hearing impairment.<br>Föreliggande avhandling tillhör ämnet handikappvetenskap och beskriver specifika kognitiva förmågor hos personer med Ushers syndrom typ 1 och 2. Avhandlingens ämne har undersökts utifrån ett tvärvetenskapligt perspektiv, även om de teorier som tillämpas och beskrivs huvudsakligen härrör inom området kognitiv psykologi. Ushers syndrom är en ovanlig genetisk åkomma som leder till kombinationen av syn- och hörselnedsättning: dövblindhet. Individer med typ 1 av syndromet har medfödd dövhet medan individer med typ 2 har en medfödd måttlig till grav hörselnedsättning. Någon gång i åldrarna 6-10 år börjar de första symptomen, till exempel nedsatt mörkerseende, på den genetiskt betingade progressiva synnedsättningen Retinitis Pigmentosa att framträda. Syndromet är väl beskrivet i forskningen med avseende på genetiska och medicinska aspekter, men det finns extremt lite tidigare forskning med kognitivt perspektiv om populationen. Studierna 1 och 2 i föreliggande avhandling fokuserade på barn med Ushers syndrom typ 1 och cochleaimplantat. Dessa studier undersökte fonologisk förmåga, lexikal access, arbetsminne och läsning i gruppen. Studie 3 undersökte samma kognitiva förmågor hos vuxna med typ 2 av syndromet. I studie 4 undersöktes även den sammansatta förmågan Theory of Mind hos de vuxna med typ 2 och deras prestation jämfördes både mot en kontroll grupp med normal hörsel och syn och en kontrollgrupp med annan typ av dövblindhet; Alström syndrom. Resultaten visade att både barnen och de vuxna med Ushers syndrom hade signifikant sämre fonologisk förmåga än kontrollgruppen med normal hörsel. Nivån på prestation varierade stort inom grupperna, särskilt mellan barnen med typ 1, och flera av individerna (barn och vuxna) presterade trots hörselnedsättningen på samma nivå som de normalhörande. Läsfärdigheten befanns vara i nivå med kontrollgrupperna. I den vuxna gruppen var det stor variation i prestation även på Theory of Mind, men de flesta av individerna presterade liknande som kontrollgruppen med normal hörsel och syn. Föreliggande projekt har resulterat i lite mer kunskap om kognitiva färdigheter hos individer med Ushers syndrom typ 1 och 2. De resultat som individerna med Ushers syndrome presterade kan till stor del förstås och tolkas genom tillämpning av teorier och modeller utvecklade för att den inverkan på kognitiva förmågor det har att ha nedsatt hörsel och höra med hjälp av hörselapparat eller cochleaimplantat. Dock tyder fynden i detta projekt även på att individer med Ushers syndrom på grund av den allvarliga synnedsättningen har ytterligare svårigheter att få tillgodogöra sig information, men i vilken utsträckning och på vilket sätt är ännu inte beskrivet. Utifrån fynden i föreliggande studie blev rekommendation att interventioner och stöd till personer med Ushers syndrom utformas specifikt till varje individ, med hänsyn taget både till hens grad av synnedsättning och hörselnedsättning.

Da Finanzbildung im Idealfall schon bei Kindern und Jugendlichen ansetzt (vgl. Grohmann/Menkhoff 2015; Whitebread/Bingham 2013), hat eine Sub-Arbeitsgruppe des International Network on Financial Education (INFE), unter Mitarbeit der Österreichischen Nationalbank (OeNB), einen umfangreichen Katalog an Core Competencies für die Finanzkompetenz von Jugendlichen veröffentlicht (vgl. OECD 2015b). Dieser legt fest, welches Wissen und welche Fähigkeiten Kinder und Jugendliche im Alter von 15-18 Jahren in Bezug auf finanzielle Fragen haben sollten.
Angesichts der hohen Relevanz von Finanzbildung stellt sich ausgehend von diesem Rahmenwerk die Frage, inwieweit die Core Competencies bereits durch die Lehrstoffinhalte der Pflichtschulen in Österreich abgedeckt sind. Das Projekt Financial Core Competencies in Austria (FinCCA) knüpft mittels zweistufiger Gap-Analyse an dieser Fragestellung an: In einem ersten Schritt ist das Projekt darauf ausgerichtet zu untersuchen, inwieweit die Core Competencies durch die Lehrplaninhalte abgedeckt sind. Auf Basis der inhaltsanalytischen Auswertung der Lehrpläne werden in einem weiteren Schritt ausgewählte, in Österreich approbierte, Schulbücher analysiert. Auf Grundlage der zweistufigen Gap-Analyse sollen zentrale Unterrichtsinhalte identifiziert werden, für die abschließend Lehrkonzepte zur Lehrer/innen/bildung im Bereich Finanzbildung entwickelt werden. Insgesamt soll damit ein weiterer wissenschaftlicher Grundpfeiler für eine nationale Strategie zur Förderung von Finanzbildung im Sinne der OECD (vgl. OECD 2015a) geschaffen werden. FinCCA wird als gemeinsames Projekt der Wirtschaftsuniversität Wien, der Karl-Franzens-Universität Graz und der Österreichischen Nationalbank (OeNB) durchgeführt.
Dieser Artikel gibt unter Berücksichtigung des Forschungstands einen Einblick in die Zielsetzung, das Projektdesign und ausgewählte Projektergebnisse. Die Ergebnisse geben einen Einblick inwiefern bestimmte inhaltliche Themenbereiche grundlegender Finanzbildung bereits innerhalb des Lehrstoffes österreichischer Pflichtschulen berücksichtigt sind. Der Artikel schließt mit Ansatzpunkten zur Verbesserung grundlegender Finanzbildung und gibt einen Ausblick über die weitere Vorgehensweise.
