Malcolmson, Elaine. "Coming to terms : an investigation of free-choice learning, scientific literacy and health literacy." Thesis, University of Glasgow, 2015. http://theses.gla.ac.uk/6397/.
Full textAbstract:
The term free-choice learning has received relatively recent support, having been favoured by John Falk from around 2001. Free-choice learning can be described most simply as “the type of learning that occurs most frequently outside of school” (Falk, 2001, p.6). Free-choice science learning has connections with the research areas of science communication, the public understanding of science, public engagement with science and, in particular, informal learning. Additionally, Falk introduced the idea of working knowledge of science as, “knowledge generated by the learner’s own interests and needs” (Falk, Storksdieck and Dierking, 2007, p.464). This thesis explored the terms free-choice learning and working knowledge of science in order to gain a better understanding of their meaning and their importance. The work was carried out to address the following research questions: 1. Can the BodyWorks exhibits be used as a tool to provide evidence of free-choice learning and working knowledge? 2. Can the BodyWorks exhibits be used as a tool to gain a better understanding of free-choice learning and working knowledge? 3. What can be gained from revisiting scientific and health literacy concepts from the perspective of free-choice learning and working knowledge? 4. Can best practice with regards to free-choice learning and working knowledge be shared between the fields of scientific and health literacy? Glasgow Science Centre’s BodyWorks exhibits were used as a tool to empirically investigate free-choice learning and working knowledge. Data were gathered using semi-structured interviews and staff diaries. It was found that 93% of participants referred to some type of free-choice learning experience when discussing the BodyWorks exhibits. A better understanding of free-choice learning and working knowledge was achieved. Free-choice learning and working knowledge were used as a lens through which to revisit the concepts and definitions of scientific literacy and health literacy. This theoretical work provided an insight to key themes developing in this literature and directions for future research. The results of both the empirical and theoretical parts of this thesis combined to produce implications for free-choice learning providers, formal education, the health sector and society. Most importantly the results presented ideas on how these groups could utilise free-choice learning and working knowledge to their benefit.

Yucelen, Tansel. "Advances in adaptive control theory: gradient- and derivative-free approaches." Diss., Georgia Institute of Technology, 2011. http://hdl.handle.net/1853/43731.
Full textAbstract:
In this dissertation, we present new approaches to improve standard designs in adaptive control theory, and novel adaptive control architectures.
We first present a novel Kalman filter based approach for approximately enforcing a linear constraint in standard adaptive control design. One application is that this leads to alternative forms for well known modification terms such as e-modification. In addition, it leads to smaller tracking errors without incurring significant oscillations in the system response and without requiring high modification gain. We derive alternative forms of e- and adaptive loop recovery (ALR-) modifications.
Next, we show how to use Kalman filter optimization to derive a novel adaptation law. This results in an optimization-based time-varying adaptation gain that reduces the need for adaptation gain tuning.
A second major contribution of this dissertation is the development of a novel derivative-free, delayed weight update law for adaptive control. The assumption of constant unknown ideal weights is relaxed to the existence of time-varying weights, such that fast and possibly discontinuous variation in weights are allowed. This approach is particularly advantageous for applications to systems that can undergo a sudden change in dynamics, such as might be due to reconfiguration, deployment of a payload, docking, or structural damage, and for rejection of external disturbance processes.
As a third and final contribution, we develop a novel approach for extending all the methods developed in this dissertation to the case of output feedback. The approach is developed only for the case of derivative-free adaptive control, and the extension of the other approaches developed previously for the state feedback case to output feedback is left as a future research topic.
The proposed approaches of this dissertation are illustrated in both simulation and flight test.

Full textAbstract:
I propose a simple approach to trade cooperation in economic shocks. A two-country, two-good trade model provides a stage setting. In a dynamic model, international demand for traded goods is allowed to be subject to sudden shocks. Numerical simulations predict that negative, sustained demand shocks may spark trade wars. Negative demand shocks that are short relative to the period it takes for governments to detect violations render instead incentives in free trade agreements more robust. I find that the multilateral policy response to the 2008 crisis - to temporarily enhance multilateral information mechanisms - may have worked to strengthen this effect.I den här uppsatsen analyseras incitament i handelsavtal under ekonomiska chocker utifrån grundläggande spelteori. Jag finner att långa lågkonjunkturer påverkar incitamenten på ett sätt som kan få parterna att frångå avtalet och starta ett tullkrig. Korta lågkonjunkturer stärker i stället incitamenten i avtalet. Jag argumenterar för att brytpunkten mellan en tullkrigsutlösande lågkonjunktur och en incitamentstärkande lågkonjunktur kan regleras genom att tillfälligt stärka informationsmekanismerna kring avtalet och att de multilaterala åtgärderna i krisens spår kan ha haft den effekten.

Full textAbstract:
Studier visar att leken i förskolan har en stor betydelse för barnens utveckling. Pedagogens ansvar för barnens sociala samspel betonas i förskolans läroplan. Därför valde vi att genomföra vår studie med syftet att ta reda på och belysa pedagogers syn på den fria leken i förskolans verksamhet i relation till pedagogens ansvar. Studien avgränsades till synen på den egna rollen i barnens fria lek samt hur pedagogerna påverkar barnens fria lek och därmed deras utvecklingsmöjligheter ur ett pedagogperspektiv. Vi har också haft som utgångspunkt att undersöka vilka konsekvenser verksamhetens organisation får för den fria leken och barnens utveckling enligt pedagogerna.
Vi har använt oss utav en kvalitativ metod med strukturerade gruppintervjuer samt öppna kvalitativa enkäter för att få fram pedagogers syn på den fria leken i förskolan i relation till pedagogens ansvar. Sammanlagt intervjuades sex pedagoger och sju pedagoger svarade på enkäter. Urvalet är ifrån tre olika kommuner i Västra Götaland. I vår analys fick vi bland annat fram att pedagogerna anser att de har en viktig roll i barnens lek, dock påverkas leken av alla rutiner som existerar samt övriga arbetsuppgifter de har. I diskussionskapitlet reflekterar vi över ekonomins påverkan hos pedagogerna och deras val av utformningen av miljön i förskoleverksamheterna.
During the time for our education there has often been a discussion about children’s playing and the responsibility of the teacher related to it. That’s why we chose to do this study with the purpose of identifying the teacher’s role in children’s development and play time in pre-school. Among other things there has been a starting point in making out what consequences organized play time would get according to the teachers, how it would affect the children and how they relate to this.
We used an empirical research method where we used both structured group interviews and open qualitative surveys to get insight in a few selected teachers’ views around play time. A total of six teachers were interwied and seven teachers responded to questionnaires. The sample is from three different municipalities in Västra Götaland. In our analysis did we come to the conclusion that the teachers believe that they have an important role in children’s playing but that the play is affected by all the routines and other tasks they have. In the final discussion we reflect on what impact the economy has with the teachers and their choices they make regarding the way the environment looks in pre-schools.

Full textAbstract:
Ce travail est consacré au développement de schémas numériques pour approcher les solutions de modèles d'écoulement type “depth averaged”. Dans un premier temps, nous détaillons la construction d'approches Volumes Finis pour le système Shallow Water avec termes sources sur maillages non structurés. En se basant sur une reformulation appropriée des équations, nous mettons en place un schéma équilibré et préservant la positivité de la hauteur d'eau, et suggérons des extensions MUSCL adaptées. La méthode est capable de gérer des topographies irrégulières et exhibe de fortes propriétés de stabilité. L'inclusion des termes de friction fait l'objet d'une analyse poussée, aboutissant à l'établissement d'une propriété type “Asymptotic Preserving” à travers l'amélioration d'un autre récent schéma Volumes Finis. La seconde composante de cette étude concerne les méthodes Elements Finis type Galerkin discontinu. Certaines des idées avancées dans le contexte Volumes Finis sont employées pour aborder le système Shallow Water surmaillages triangulaires. Des résultats numériques sont exposés et la méthode se révèle bien adaptée à la description d'une large variété d'écoulements. Partant de ces observations nous proposons finalement d'exploiter ces caractéristiques pour étendre l'approche à une nouvelle famille d'équations type Green-Nadghi. Des validations numériques sont également proposées pour valider le modèle numériqueThis work is devoted to the development of numerical schemes to approximatesolutions of depth averaged flow models. We first detail the construction of Finite Volume approaches for the Shallow Water system with source terms on unstructured meshes. Based on a suitable reformulation of the equations, we implement a well-balanced and positive preserving approach, and suggest adapted MUSCL extensions. The method is shown to handle irregular topography variations and demonstrates strong stabilities properties. The inclusion of friction terms is subject to a thorough analysis, leading to the establishment of some Asymptotic Preserving property through the enhancement of another recent Finite Volume scheme.The second aspect of this study concerns discontinuous Galerkin Finite Elementmethods. Some of the ideas advanced in the Finite Volume context areemployed to broach the Shallow Water system on triangular meshes. Numericalresults are exposed and the method turns out to be well suited to describe a large variety of flows. On these observations we finally propose to exploit its features to extend the approach to a new family of Green-Nadghi equations. Numerical experiments are also proposed to validate this numerical model

The thesis covers methods for image segmentation. Fuzzy segmentation is based on the thresholding method. This is generalized to accept multiple criteria. The whole process is mathematically based on the free algebra theory. Free distributive lattice is created from poset of elements based on image properties and the lattice members are represented by terms used by the threshoding. Possible segmentation results compose the equivalence classes distribution. The thesis also contains description of resulting algorithms and methods for their optimization. Also the method of area subtracting is introduced.

Full textAbstract:
Geographical indications designate products which have a specific geographical origin, which can either be national, regional or local. The subject is complicated since geographical indications arises a large number of questions There are EC regulations which regulate the protection of geographical indications, but since the field has not yet been exhaustively harmonized, the existence of national rules of protection is therefore still possible, which can lead to trade barriers between the member states. Consequently, one problem consists in whether it may be legitimate to restrict the free movement of goods by article 28 in the EC Treaty by referring to national rules of protection and to what extent such measures may be justified by article 30 or by the Cassis doctrine. An additional question consists in how the line between geographical indications and generic terms is to be established appropriately. Further, geographical indications are exposed to improper use by other dishonest commercial operators and therefore the possibilities of protection against unfair competition and misleading are also discussed in the thesis. Since there are several questions which are unanswered regarding geographical indications, the purpose of this essay is to analyze what kind of intellectual property right geographical indications constitute and how they are protected.

Nesta tese é apresentado um esquema novo de alta resolução upwind (denominado TDPUS-C3) para reconstrução de fluxos numéricos para leis de conservação não lineares e problemas relacionados em DFC. O esquema é baseado nos critérios de estabilidade CBC e TVD e desenvolvido utilizando condições de diferenciabilidade \'C POT. 3\'. Além disso, é realiozada a implementação da associação do esquema TDPLUS-C3 com a modelagem de turbulência RNG \'\\kappa - \\epsilon\'. O propósito é obter soluções numéricas de sistemas hiperbólicos de leis de conservação para dinâmica dos gases e equações de Navier-Stokes para escoamento incompreensível de fluidos newtonianos e não newtonianos (viscoelásticos). Fazendo o uso do esquema TDPUS-C3, a precisão global dos métodos numéricos é verificada acessando o erro em problemas teste (benchmark) 1D e 2D. Um estudo comparativo entre os resultados do esquema TDPUS-C3 e os esquemas upwind convencionais para leis de conservação hiperbólicas complexas é também realizado. A Associação das modelagens numéricas (upwinding mais RNG \'\\kappa - \\epsilon\') é , então, examinada na simulação de escoamentos turbulentos de fluidos newtonianos envolvendo superfícies livres móveis, usando a metodologia URANS. No geral, em termos do comportamento global, concordância satisfatória é observadaIn this thesis, a new high-resolution upwind scheme (named TDPUS-C3) for reconstruction of numerical fluxes for nonlinear conservation laws and related CFD problems in presented. The scheme is based on CBC and TVD stability criteria and developed by employing differentiability condictions (\'C POT. 3\'). In additon, the implementation of an association of the TDPUS-C3 scheme with the RNG \'\\kappa - \\epsilon\' turbulence modelling is also performed. The purpose is to obtain numerical solutions of systems of hyperbolic conservation laws for gas dynamics and Navier-Stokes equations for incompressible flow of Newtonian and non-Newtonian (viscoelstic) fluids. By using the TDPUS-C3 scheme, the global accuracy of the numerical methods is verified by assessing the error on 1D and 2D benchmark test cases. A comparative study between the TDPUS-C3 scheme and convectional upwind schemes to solve standard and complex hyperbolic conservation laws is also accomplished. The association of the numerical modelling (upwinding plus RNG \'\\kappa - epsilon\') is then examined in the simulation of turbulent Newtonian fluid flows involving moving free surfaces, by using URANS methodology. Overall, satisfactory agreement is found in terms of the overall behaviour

O estudo concentra-se na primeira metade do século XIX, momento inicial do processo de construção das bases do Estado-Nação. Buscamos lançar olhares sobre o Termo de Mariana na intenção de compreender em que medida o processo de escolarização dos negros livres e libertos ocorrido naquele contexto, se relacionou com a experiência da cidadania que se construía no contexto brasileiro durante o Império. A instrução pública enquanto um direito civil, e a experiência dos livres e libertos com a instrução nos levou a forjar interpretações sobre a natureza do Estado-Nação que se pretendia formar. A existência da igualdade civil, que surge a partir de 1824 com a Constituição, na medida em que se incorpora em uma sociedade marcada pelo escravismo e por fortes tensões de cunho racial, ao invés de gerar maior igualdade social, acabou se constituindo, de maneira sui generis, em fator de contribuição a uma maior complexidade das hierarquias sociais. Estas eram, em grande medida, provenientes de uma necessidade fundamental dos segmentos sociais atingidos pela questão racial, qual seja, a de se afastar do estigma da escravidão, recorrendo a condição de membros da sociedade civil. Nesse âmbito, o acesso `a instrução na sociedade imperial por negros contribuíram não somente com a legitimação, mas especialmente com a complexificação das hierarquias sociais na sociedade, sempre buscando se afastar do estigma da escravidão.
The study focuses on the first half of the nineteenth century, the initial stage of the process of building the foundations of the nation state. We seek to cast eyes on the Mariana term in an attempt to understand to what extent the process of schooling of free blacks and freed occurred in that context, was related to the experience of citizenship was being built in the Brazilian context during the Empire. Public education as a civil right, and the experience of free and freed through education led us to forge interpretations of the nature of the nation-state that was intended to form. The existence of civil equality, which comes from 1824 with the Constitution, in that it is incorporated in a society marked by slavery and by strong tensions of racial nature, rather than generate greater social equality, eventually constituting, so sui generis, in contributing factor to greater complexity of social hierarchies. These were, largely, from a fundamental need of social groups affected by the racial question, namely, to get away from the stigma of slavery, using capacity as members of civil society. In this context, access `training in imperial society by blacks contributed not only to the legitimacy but especially with the complexity of social hierarchies in society, always looking to get away from the stigma of slavery.

Full textAbstract:
The objectives of this dissertation were to investigate the utility of cf-DNA as a marker of systemic inflammation, fatigue, and training status in a long-term athlete monitoring program (LTAMP). In study one, cf-DNA, other biochemical markers, volume load, and training intensity were measured in weightlifters over 20 weeks. The changes and relationships between these variables were investigated in order to determine which variables may be indicative of an athlete’s training status. In study two, cf-DNA, other biochemical markers, and session rating of perceived exertion (sRPE) were measured over the course of a 15-week soccer season in order investigate the utility of cf-DNA as an indicator of systemic inflammation and fatigue. In study one, CK was statistically greater T2 than T4, T5, and T6 at p = 0.015, 0.025, and 0.030 respectively. cf-DNA %Δ was correlated with CRP percent change and BF% (r = 0.86 and r = 0.91 respectively). The correlation between cf-DNA and CRP suggests that cf-DNA may be a valuable indicator of inflammation. Upon further visual inspection, cf-DNA and CRP also appeared to rise and fall with changes in volume load with displacement (VLwD). In study 2, G1, cf-DNA (P = 0.001), CRP (P = 0.000), CK (P = 0.003), cf-DNA %Δ (P = 0.002), CRP %Δ (P = 0.002), and CK %Δ (P = 0.002) were all significantly higher than T1 at T2 and T3. In G2, CRP (P = 0.057) and CRP %Δ (P = 0.039) were significantly higher at T2 than T1. Despite the lack of statistically significant differences across all 3 testing times, cf-DNA %Δ, CRP %Δ, and CK %Δ increased throughout the season in G1. In G2, cf-DNA %Δ, CRP %Δ, and CK %Δ were all higher at T2 and T3 than T1 but fewer significant differences were present, potentially a result of the lower sRPE values in G2 versus G1.These results suggest that cf-DNA may a useful marker to reflect accumulated training and competitive stressors. The correlation between cf-DNA and CRP in study 1 suggests that cf-DNA may be a valuable indicator of inflammation.

Full textAbstract:
Effects of short-term free-weight and semiblock periodization resistance training on metabolic syndrome. J Strength Cond Res 30(10): 2682–2696, 2016—The effects of short-term resistance training on performance and health variables associated with prolonged sedentary lifestyle and metabolic syndrome (MS) were investigated. Resistance training may alter a number of health-related, physiological, and performance variables. As a result, resistance training can be used as a valuable tool in ameliorating the effects of a sedentary lifestyle including those associated with MS. Nineteen previously sedentary subjects (10 with MS and 9 with nonmetabolic syndrome [NMS]) underwent 8 weeks of supervised resistance training. Maximum strength was measured using an isometric midthigh pull and resulting force-time curve. Vertical jump height (JH) and power were measured using a force plate. The muscle cross-sectional area (CSA) and type were examined using muscle biopsy and standard analysis techniques. Aerobic power was measured on a cycle ergometer using a ParvoMedics 2400 Metabolic system. Endurance was measured as time to exhaustion on a cycle ergometer. After training, maximum isometric strength, JH, jump power, and V[Combining Dot Above]O2peak increased by approximately 10% (or more) in both the metabolic and NMS groups (both male and female subjects). Over 8 weeks of training, body mass did not change statistically, but percent body fat decreased in subjects with the MS and in women, and lean body mass increased in all groups (p ≤ 0.05). Few alterations were noted in the fiber type. Men had larger CSAs compared those of with women, and there was a fiber-specific trend toward hypertrophy over time. In summary, 8 weeks of semiblock free-weight resistance training improved several performance variables and some cardiovascular factors associated with MS.

Full textAbstract:
Cette thèse étudie les principes de mise en oeuvre pour l'exécution sur un même ordinateur, de tâches de niveaux de criticité différents, et dont certaines peuvent avoir des contraintes temps réel dur. Les difficultés pour réaliser ces objectifs forment trois catégories. Il faut d'abord prouver que les tâches disposeront d'assez de ressources pour s'exécuter; il doit être ainsi possible d'avoir des politiques d'allocations et d'ordonnancement sûres, prévisibles et simples. Il faut également apporter des garanties de sécurité pour s'assurer que les tâches critiques s'exécuteront correctement en présence de défaillances ou malveillances. Enfin, le système doit pouvoir être réutilisé dans une variété de situations. Cette thèse propose de s'attaquer au problème par la conception d'un système hautement sécurisé, extensible, et qui soit indépendant des politiques d'allocation de ressources. Cela est notamment accompli par le prêt de ressource, qui permet de décompter les ressources indépendamment des domaines de protection. Cette approche évite d'avoir à partitionner les ressources, ce qui simplifie le problème global de l'allocation et permet de ne pas gâcher de ressources. Les problèmes de type inversion de priorité, famine ou dénis de service sont supprimés à la racine. Nous démontrons la faisabilité de cette approche è l'aide d'un prototype, Anaxagoros. La démarche que nous proposons simplifie drastiquement l'allocation des ressources mais implique des contraintes dans l'écriture de services partagés (comme les pilotes de périphériques). Les principales difficultés consistent en des contraintes de synchronisation supplémentaires. Nous proposons des mécanismes originaux et efficaces pour résoudre les problèmes de concurrence et synchronisation, et une méthodologie générale pour faciliter l'écriture sécurisée de ces services partagés.

As a result, resistance training can be used as a valuable tool in ameliorating the effects of a sedentary lifestyle including those associated with MS. Nineteen previously sedentary subjects (10 with MS and 9 with nonmetabolic syndrome [NMS]) underwent 8 weeks of supervised resistance training. Maximum strength was measured using an isometric midthigh pull and resulting force-time curve. Vertical jump height (JH) and power were measured using a force plate. The muscle cross-sectional area (CSA) and type were examined using muscle biopsy and standard analysis techniques. Aerobic power was measured on a cycle ergometer using a ParvoMedics 2400 Metabolic system. Endurance was measured as time to exhaustion on a cycle ergometer. After training, maximum isometric strength, JH, jump power, and V_ O2peak increased by approximately 10% (or more) in both the metabolic and NMS groups (both male and female subjects). Over 8 weeks of training, body mass did not change statistically, but percent body fat decreased in subjects with the MS and in women, and lean body mass increased in all groups (p # 0.05). Few alterations were noted in the fiber type. Men had larger CSAs compared those of with women, and there was a fiber-specific trend toward hypertrophy over time. In summary, 8 weeks of semiblock free-weight resistance training improved several performance variables and some cardiovascular factors associated with MS

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgicoO interesse de pesquisadores pelo estudo do sistema proprioceptivo vem crescendo nas Ãltimas dÃcadas. Isto à decorrente da importÃncia da integridade deste sistema no tratamento das enfermidades ortopÃdicas. Os mecanorreceptores e as terminaÃÃes nervosas livres sÃo as unidades microscÃpicas fundamentais da propriocepÃÃo e do sistema nervoso aferente. Eles transmitem ao sistema nervoso central informaÃÃes fisiolÃgicas em forma de potencial de aÃÃo, quando as estruturas articulares, cÃpsula, ligamentos e mÃsculos, sÃo submetidas ao estresse do movimento. Foram avaliadas a presenÃa e a densidade dos mecanorreceptores na cÃpsula, ligamento da cabeÃa femoral e labrum acetabular de 45 quadris masculinos. Destes, 30 foram obtidos de pacientes do sexo masculino com artrose secundÃria (grupo I) durante artroplastia e 15 de cadÃveres frescos com articulaÃÃo do quadril normal (grupo II). A idade mÃdia do grupo I foi de 56,5 e do grupo II foi de 35,6 anos. Os fragmentos obtidos foram mensurados em 2mm e corados com cloreto de ouro a 1%. ApÃs fixaÃÃo os fragmentos foram seccionados com criostato, em sÃrie de 6 micrÃmetros de espessura e submetidos à microscopia de luz. Foram identificados trÃs tipos de mecanorreceptores: Ruffini, Pacini e Golgi, alÃm das terminaÃÃes nervosas livres de acordo com a classificaÃÃo de Freeman e Wike (1967). Em cada grupo foi determinado o nÃmero e a densidade de mecanorreceptores e em seguida foram comparados os resultados. Concluiu-se que o predomÃnio das terminaÃÃes tipo Pacini no gurpo controle foi significante quando comparado com os corpÃsculos tipo Rufini (p < 0,01) e Golgi (p < 0,001).Enquanto que no grupo artrose a densidade do tipo Golgi foi menor que o tipo Pacini(p < 0,001) e terminaÃÃes nervosas livres( p < 0,01).Por outro lado, quando comparados a densidade total das terminaÃÃes nervosas nos dois grupos observou-se uma reduÃÃo significante nos quadris artrÃsicos (p = 0.008). Isto sugere fortemente que a integridade do sistema proprioceptivo parece sofrer modificaÃÃes em quadris artrÃsicos, como conseqÃÃncia da reduÃÃo do nÃmero de terminaÃÃes nervosas. Estudos eletrofisiolÃgicos futuros serÃo necessÃrios para definir o papel das terminaÃÃes nervosas e o padrÃo proprioceptivo do quadril normal do quadril artrÃsico.
Proprioceptive studies have reported growing interest in investigators in the last few decades. This is result of relevant integrity of this system in the treatment of orthopedic diseases. Mechanoreceptors and free nerve endings are the microscopy basic units from proprioception and peripheral nervous system. They transmit to the central nervous system physiological information with detection threshold when the joint are submitted to mechanical stress. The presence and density of mechanoreceptors were investigated in the capsule, teres ligament and acetabulum labrum from 45 hips joint. Of these 30 were obtained from male patients (Group I) with secondary arthrosis at open arthoplasty and 15 of fresh cadaver with normal hip joint (Group II). The mean age of group I was 56,6 and the group II was 36,5 years. The fragments obtained were measured up to 2mm and stained with gold chloride 1%. After fixation the fragments were sectioned with cryostat at serial sections of 6Âm thickness and examined using light microscopy. We identified 3 types of mechanoreceptors: Ruffini, Pacini and Golgi corpuscles, as well free nerve endings according of Freeman and Wike classified 1967. Each group was determined the number and density of mechanoreceptors and then it was compared. We conclude that the number of Pacini type was significative when it was compared with Rufini ( p < 0,01 ) and Golgi types (p< 0,001), in the normal group. However, the denstity of the Golgi type was minor compared to the Pacini ( p < 0,001) and free nerve ending ( p < 0,01 ) in the arthrosis group. Therefore, when the density total of nerve endings in normal hips were compared with arthosis hips we founded that the number decreased (p = 0.008). This is suggests strongly that the integrity of proprioceptive system seems to be modified by arthosis in consequence of nerve endings numbers. In the future, electrophysiological studies will be necessary to determine the rule of nerve endings and proprioceptive system in the normal and arthosis hip.

Full textAbstract:
Childlessness, whether voluntary, involuntary or circumstantial, is becoming more common in our society. Statistically, greater numbers of Australian women and their Western counterparts will not bear children, thereby creating a larger quantum of couple families. The unwelcome socio-economic consequences have prompted research into reproductive intentions and behaviour to address barriers to reproduction. Studying those who are childless by ‘choice’ or ‘infertile’ provides important ‘reference points’ but also creates a myopic view of the childless that often overlooks circumstantial factors or ignores the fluctuating nature of fertility intentions. Moreover, the medical discourse on infertility has conditioned our thinking and focused research on the psycho-social effects and impacts of assisted reproduction treatment and its failure. This has blurred and obscured the distinction between infertility and involuntary childlessness. Too often these are viewed through the same prism of grief and bereavement as a temporary but pervasive ‘crisis’ and as impediments to adult development in the long term. The thesis provides new insights that challenge our conventional ways of thinking particularly its findings that although infertility and childlessness are related, they are separate phenomena. This has wide-ranging implications, especially for reformulating related clinical practice and counselling. There are several important considerations. One is the finding that the grief and bereavement model has its limitations beyond the infertility stage. Another is the theoretical reconstruction that the thesis provides of the grief that the involuntary childless experience. Finally, it makes a strong case for a more appropriate alternative which the thesis argues should be based on a growth-oriented model. The time point at which the information for this study was collected has rarely ever been used before. This adds significant weight to the findings and applications that potentially derive from them. The thesis also examines gender issues including the complexities in differential experiences, amongst and across gender categories. It builds on the existing body of knowledge on the gendered experience of involuntary childlessness and offers additional explanations for the variations found, around which clinical interventions should be framed. Overall, this study makes an important contribution to our knowledge and understanding by documenting the transitional process to involuntary childlessness in broader terms than has hitherto been the case. Contrary to conventional thinking related to adult development, the findings underscore the importance of viewing involuntary childlessness as an alternative developmental pathway.

Full textAbstract:
Corrosion of steel reinforcements is the leading causes of malfunction or even failures of reinforced concrete (RC) structures nationwide and worldwide for many decades. This arises up to substantial economic burden on repairs and rehabilitations to maintain and extend their service life of those RC public projects. The inherent natures of glass fiber-reinforced polymers (GFRP) bars, from their superior corrosion resistance to high strength-to-weight ratio, have promoted their acceptance as a viable alternative for steel reinforcement in civil infrastructures. Comprehensive understanding of the bond between GFRP bars and concrete, in particular under in-service conditions or extremely severe events, enables scientists and engineers to provide their proper design, assessment and long-term predictions, and ultimately to implement them toward the corrosion-free concrete products. This research aims to develop a holistic framework through an experimental, analytical and numerical study to gain deep understanding of the bond mechanism, behavior, and its long-term durability under harsh environments. The bond behavior and failure modes of GFRP bar to concrete are investigated through the accelerated aging tests with various environmental conditions, including alkaline and/or saline solutions, freezing-thawing cycles. The damage evolution of the bond is formulated from Damage Mechanics, while detailed procedures using the Arrhenius law and time shift factor approach are developed to predict the long-term bond degradation over time. Besides, the machine learning techniques of the artificial neural network integrated with the genetic algorithm are used for bond strength prediction and anchorage reliability assessment. Clearly, test data allow further calibration and verification of the analytical models and the finite element simulation. Bond damage evolution using the secant modulus of the bond-slip curves could effectively evaluate the interface degradation against slip and further identify critical factors that affect the bond design and assessment under the limit states. Long-term prediction reveals that the moisture content and elevated temperature could impact the material degradation of GFRP bars, thereby affecting their service life. In addition, the new attempt of the Data-to-Information concept using the machine learning techniques could yield valuable insight into the bond strength prediction and anchorage reliability analysis for their applications in RC structures.ND NASA EPCoR (FAR0023941)

Full textAbstract:
Individual differences on complex memory spans predict a variety of higher-order cognitive tasks (e.g. reading comprehension, reasoning, following direction) as well as low-level attention tasks (e.g. Stroop, dichotic listening, antisaccade). The current study attempted to better determine the role of individual differences in complex memory span and episodic retrieval. Specifically, two experiments explored the possibility that individual differences in complex memory span reflect differences in the ability to successfully retrieve items from secondary memory via a cue-dependent search process. High and low complex span participants were tested in delayed (Experiment 1) and continuous distractor (Experiment 2) free recall with varying list-lengths. Across both experiments low spans recalled fewer items than high spans, recalled more previous list intrusions than high spans, and recalled at a slower rate than high spans. It is argued that low spans search through a larger set of items than high spans and, thus low spans episodic retrieval deficits are associated with an inability to use cues to guide a search and retrieval process of secondary memory. Implications for dual-component models of memory are discussed.

Full textAbstract:
BACKGROUND: Obstetric fistula (OF) is described as a health and human rights tragedy due to its devastating consequences and debilitating sequelae. In sub-Saharan Africa, the lifetime prevalence of OF symptoms is estimated at 3.0 cases (95% CI 1.3-5.5) per 1000 women of reproductive age. In Guinea, this prevalence is 6·0 (95% CI 3·9–7·4) per 1000 women of reproductive age, a double that of sub-Saharan Africa. As maternal mortality reduction is accelerating in many countries due to better access to cesarean section and more women are benefiting treatment for OF worldwide, women who have a successful fistula repair need more attention to prevent fistula recurrence and adverse maternal and neonatal outcomes.AIM: To analyze the long-term reproductive health outcomes in women who undergo fistula surgery in Guinea and contribute to closing the knowledge gap on the reproductive health of women after fistula surgery.METHODS: The situational analysis of fistula management programs in Guinea included three retrospective cohort studies. Study I analyzed the clinical outcomes of fistula care programs in Guinea. Study II analyzed the trends and factors associated with loss to follow-up after surgical repair of obstetric fistula in Guinea. Study III estimated the overall proportions of surgical failure of fistula closure and incontinence among women undergoing repair for obstetric fistula in Guinea and identified factors associated with these outcomes. To analyze the health and reproductive outcomes in women after female genital fistula surgery in Guinea, two studies (IV and V) were conducted. Study IV critically reviewed the existing literature on pregnancy and childbirth post repair of obstetric fistula and Study V analyzed the incidence of fistula recurrence and pregnancy post repair along with the associated maternal and neonatal outcomes. RESULTS: Routine programmatic repair of OF was found to achieve satisfactory short-term clinical outcomes with 85% of women having their fistula closed and 79% becoming continent after surgery (Study I). However, additional 18% recurrence and 10% residual urinary incontinence were recorded within 28 months median follow-up post-surgery (Study V). Reimbursement of transportation costs and the reduction of geographical barriers to care for women with OF were highly related to reduced loss to follow-up after hospital discharge (Study II). Women who present for surgery with a damaged urethra and those who delivered vaginally during the delivery leading to the fistula were more likely to experience surgical repair failure and residual urinary incontinence (Study III). Women who become pregnant and deliver after fistula repair in sub-Saharan Africa were identified as carrying high risk of adverse maternal and neonatal health outcomes (Study IV). In Guinea, only few women achieved pregnancy (28%) after surgery. Stillbirths (24%) and recurrence of fistula after delivery (14%) were common among women who delivered after fistula repair (Study V). CONCLUSIONS: Improving the performance of fistula management programs in the context of decentralization of services in Guinea needs therefore to integrate long-term perspectives. This should include establishing a “level of care framework” into fistula surgery along with training for health providers, tracing of women after repair, and increased community awareness-raising that include men and target gender inequalities (Studies I to III). Increasing funding and support for fistula care from both local governments and international donors is needed in the current context of decentralization of fistula care to address service gaps for women suffering from fistula (Studies III to V). Achieving a fistula free generation should include interventions to address women’s vulnerability before fistula formation and after fistula repair (Studies IV and V).Doctorat en Sciences de la santé Publique

Full textAbstract:
On 10 May 1994 the European Union offeredSouth Africa a package of measures to ... send a strong political signal to the incoming govemment and to the South African population, thus proving its firm determination to support the transition towards democracy and its willingness to contribute to the reconstruction and economic development of South Africa after the elections. This package consisted of two parts: 1. A series of short term implementations to take place with immediate effect to help South Africa's development and transition, and 2. An offer to negotiate a comprehensive long-term relationship with South Africa should the new government so request. South Africa accepted the European Union's offer to negotiate a long-term relationship, and in response requested membership of the structure governing the Union's relations with the rest of the countries in Sub-Saharan Africa and some countries in the Caribbean and Pacific, namely the Lomé Convention. Due to various incompatibilities South Africa was not allowed to join this organisation. In its place the European Union offered to negotiate an agreement with South Africa that would lead to a Free Trade Area. This agreement was in keeping with the rules as laid down by the World Trade Organisation. It envisaged the lowering of tariffs and trade barriers between the Union and South Africa over a period not exceeding 12 years, allowing for asymmetry in terms of time constraints in implementation only. South Africa saw this type of agreement as inconsistent with the desire expressed by the European Union to support the countries development and the integration of the Southern African region. In its place South Africa proposed a new concept in trade agreement, this concept, known as the Trade and Development Agreement, embodied both trade liberalisation and support for development. This agreement would introduce a new paradigm of thought to govern trade between developed countries and developing countries within the World Trade Organisation's rules. This paper explores the events that unfolded in these negotiations. It attempts to discover whether, in the current global environment, it is possible, or beneficial, for the developed world to act in an altruistic manner towards another state in order to assist its development.

Fundamental concepts related to the topic are recalled and he construction of second and higher order schemes for steady problems is presented. The generalization to time dependent problems by means of multi-step implicit time integration, space-time, and genuinely explicit techniques is thoroughly discussed. Finally, the issues of C-property, super consistency, and wetting/drying are analyzed in this framework showing the power of the residual based approach.

Full textAbstract:
In this thesis we use Markov chain Monte Carlo (MCMC) simulation to calibrate a two-factor arbitrage-free model for the term structure of interest rates which is proposed by Cairns (2004a) based on the positive-interest framework (Flesaker and Hughston, 1996). The model is a time-homogeneous model driven by latent state variables which follow a two-dimensional Ornstein-Uhlenbeck process. A number of MCMC algorithms are developed and employed for estimating both model parameters and latent variables where simulated data are used in the first place in order to validate the algorithms and ensure that they can result in reasonable and reliable estimates before using UK market data. Once the posterior estimates are obtained, we next investigate goodness of fit of the model and eventually assess the impact of parameter uncertainty on the forecasting of yield curves in which the achieved MCMC output can be used directly. Additionally, the developed algorithm is also applied for estimating the two-factor Vasicek term structure model for comparison. We conclude that our algorithms work reasonably well for estimating the Cairns term structure model. The model is then fitted to UK Strips data, and it found to produce reasonable fits for medium- and long-term yields, but we also conclude that some improvement may be required for the short-end of the yield curves.

It has been suggested that psychosocial stress influences situational fluctuations of tic frequency. However, evidence from experimental studies is lacking. The current study investigated the effects of the Trier Social Stress Test (TSST-C) on tic frequency in 31 children and adolescents with tic disorders. A relaxation and a concentration situation served as control conditions. Patients were asked either to suppress their tics or to “tic freely.” Physiological measures of stress were measured throughout the experiment. The TSST-C elicited a clear stress response with elevated levels of saliva cortisol, increased heart rate, and a larger number of skin conductance responses. During relaxation and concentration, the instruction to suppress tics reduced the number of tics, whereas during stress, the number of tics was low, regardless of the given instruction. Our study suggests that the stress might result in a situational decrease of tic frequency.

The uncertainty attached to future movements of interest rates is an essential part of the Financial Decision Theory and requires an awareness of the stochastic movement of these rates. Several approaches have been proposed for modeling the one-factor short rate models where some lead to arbitrage-free term structures. However, no definite consensus has been reached with regard to the best approach for interest rate modeling. In this work, we briefly examine the existing one-factor interest rate models and calibrate Vasicek and Hull-White (Extended Vasicek) Models by using Turkey's term structure. Moreover, a trinomial interest rate tree is constructed to represent the evolution of Turkey&rsquo

Full textAbstract:
The Heath-Jarrow-Morton (HJM) model represents the latest in powerful arbitrage-free technology for modeling the term structure and managing interest rate risk. Yet risk management strategies in the form of immunization portfolios using duration, convexity, and M-square are still widely used in bond portfolio management today. This study addresses the question of how traditional risk measures and immunization strategies perform when the term structure evolves in the HJM manner. Using Monte Carlo simulation, I analyze four HJM volatility structures, four initial term structure shapes, three holding periods, and two traditional immunization approaches (duration-matching and duration-and-convexity-matching). I also examine duration and convexity measures derived specifically for the HJM framework. In addition I look at whether portfolios should be constructed randomly, by minimizing their M-squares or using barbell or bullet structures. I assess immunization performance according to three criteria. One of these criteria corresponds to active portfolio management, and the other two correspond to passive portfolio management. Under active portfolio management, an asset portfolio is successfully immunized if its holding period return is greater than or equal to the holding period return of the liability portfolio. Under passive portfolio management, the closer the returns of the asset portfolio to the returns of the liability portfolio, the better the immunization performance.
The results of the study suggest that, under the active portfolio management criterion, and with the duration matching strategy, HJM and traditional duration measures have similar immunization performance when forward rate volatilities are low. There is a substantial deterioration in the immunization performance of traditional risk measures when there is high volatility. This deterioration is not observed with HJM duration measures. These results could be due to two factors. Traditional risk measures could be poor risk measures, or the duration matching strategy is not the most appropriate immunization approach when there is high volatility because yield curve shifts would often be large.
Under the active portfolio management criterion and with the duration and convexity matching strategy, the immunization performance of traditional risk measures improves considerably at the high volatility segments of the yield curve. The improvement in the performance of the HJM risk measures is not as dramatic. The immunization performance of traditional duration and convexity measures, however, deteriorates at the low volatility segments of the yield curve. This deterioration is not observed when HJM risk measures are used. Overall, with the duration and convexity matching strategy, the immunization performance of portfolios matched with traditional risk measures is very close to that of portfolios matched with the HJM risk measures. This result suggests that the duration and convexity matching approach should be preferred to duration matching alone. Also the result shows that the underperformance of traditional risk measures under high volatility is not due to their being poor risk measures, but rather due to the reason that the duration matching strategy is not an appropriate immunization approach when there is high volatility in the market.
Under the passive portfolio management criteria, the performances of traditional and HJM measures are similar with the duration matching strategy. Less than 29% of the duration matched portfolios have returns within one basis point of the target yield, whereas almost all are within 100 basis points of the target yield. These results suggest that the duration matching strategy might not be sufficient to generate cash flows close to those of the target bond. The duration measure assumes a linear relation between the bond price and the yield change, and the nonlinearities that are not captured by the duration measure might be important.
When the duration and convexity matching strategy is used, more than 36% of the portfolios are within one basis point of the target with HJM risk measures. This dramatic improvement in the immunization performance of HJM measures is not guaranteed for traditional risk measures. In fact, there are certain cases in which the performance of traditional risk measures deteriorates with the duration and convexity matching strategy. In this respect, choosing the correct risk measure is more important than the immunization strategy when passive portfolio management is pursued.
Under active portfolio management criterion, there is no significant difference among bullet, barbell, minimum M-square, and random portfolios with both duration matching and duration and convexity matching strategies. Under the passive portfolio management criterion, bullet portfolios produce closer returns to the target for short holding periods when the duration matching strategy is used. With the duration and convexity matching strategy, bullet, barbell and minimum M-square portfolios produce closer returns to the target for short holding periods. Random portfolios perform as well as bullet, barbell and minimum M-square portfolios for medium to long holding periods. These results suggest that when the duration matching strategy is used, bullet portfolios are preferable to other portfolio formation strategies for short holding periods. When the duration and convexity matching strategy is used, no portfolio formation strategy is better than the other.
Under the active portfolio management criterion, minimum M-square portfolios are successfully immunized under each yield curve shape and volatility structure considered. Under the passive portfolio management criterion, minimum M-square portfolios perform better for short holding periods, and their performance deteriorates as the holding period increases, irrespective of the volatility level. This suggests that the performance of minimum M-square portfolios is more sensitive to the holding period rather than the volatility. Therefore, minimum M-square portfolios would be preferred in the markets when there are large changes in volatility.
Overall, the results of the study suggest that, under the active portfolio management criterion and with the duration matching strategy, traditional duration measures underperform their HJM counterparts when forward rate volatilities are high. With the duration and convexity matching strategy, this underperformance is not as dramatic. Also no particular portfolio formation strategy is better than the other under the active portfolio management criterion. Under the passive portfolio management criterion, the duration matching strategy is not sufficient to generate cash flows closer to those of the target bond. The duration and convexity matching strategy, however, leads to substantial improvement in the immunization performance of the HJM risk measures. This improvement is not guaranteed for the traditional risk measures. Under the passive portfolio management criterion, bullet portfolios are preferred to other portfolio formation strategies for short holding periods. For medium to long holding periods, however, the portfolio formation strategy does not significantly affect immunization performance. Also, the immunization performance of minimum M-square portfolios is more sensitive to the holding period rather than the volatility.Ph. D.

Full textAbstract:
La dichotomie « libre-échange versus protection » structure l'analyse de la politique commerciale dans les manuels de la théorie du commerce international. En analysant les impacts respectifs de la politique libre-échangiste et de la politique protectionniste sur l'allocation des ressources et le bien-être, les modèles standard, au premier rang desquels figure le modèle HOS, concluent à l'optimalité parétienne du libre-échange. La prescription normative est alors que tous les pays devraient appliquer une politique de libre-échange qui préserve les prix justes. Cependant, les analyses empiriques mettent en lumière le décalage de cette prescription normative : les politiques commerciales pratiquées incluent, dans des proportions variées entre pays, entre industries et entre biens, des mesures qui visent, de façon simultanée et sélective, la promotion des exportations, la substitution aux importations et la création d'un accès facilité aux importations. Les politiques pratiquées ne sont donc ni strictement libre-échangistes ni strictement protectionnistes, mais mixtes a priori. Ce constat a conduit au développement de modèles analysant les conséquences sur l'équilibre général de l'application de divers instruments de politique commerciale et spécifiant les différentes formes potentielles de cette politique. Notamment, il est expliqué que la politique commerciale mixte constitue une politique alternative. Les interventions sélectives qui la composent sont alors justifiées par la présence d'avantages comparatifs dynamiques qui conditionnent et orientent ces interventions vers des industries singulières dont la production est destinée au marché national et/ou au marché international. Mais l'assise théorique dont bénéficie ainsi la politique commerciale mixte n'aide pas à comprendre le processus politique au travers duquel cette politique est choisie. Elle ne permet pas d'ouvrir la boîte noire et de pénétrer le nucleus des choix politiques. L'économie politique le permet. L'explication théorique de l'objet « politique commerciale mixte » se situe à la croisée des deux approches constitutives du champ de recherche de l'économie politique de la protection : l'approche centrée sur la société et l'approche centrée sur l'Etat. Alors que la première approche explique que la politique est façonnée par les intérêts et les préférences des acteurs privés (ou groupes de) les plus puissants présents sur le territoire national, la seconde considère que la politique est fonction des institutions politiques et des acteurs politiques qui cherchent à satisfaire leur intérêt et leur préférence compte tenu des contraintes nationales et internationales auxquelles ils sont confrontés. La « politique commerciale mixte » peut donc s'analyser dans différentes perspectives selon les déterminants endogènes qu'on entend privilégier. Au final, la mixité de la politique commerciale résulte d'un compromis politique et institutionnel entre acteurs aux préférences hétérogènes, ce qui est partiellement remis en cause par les contraintes politiques et les influences idéationnelles internationales. Le compromis politique et institutionnel résulte de la division du gouvernement induite par un partage inégal du pouvoir de décision (fonction des institutions politiques) entre veto players (acteur composite possédant un droit de véto dans le processus de prise de décision politique), et de l'hétérogénéité de leurs préférences. La politique choisie, et les institutions associées, doivent satisfaire l'intérêt de chaque veto player, ce qui implique des mesures compensatrices et la prise en compte de l'héritage institutionnel. Non sans résistances, la flexibilité avec laquelle la politique commerciale mixte peut être utilisée est alors réduite par les contraintes politiques internationales et/ou, en amont, l'équilibre politique interne à la structure des préférences nationales modifié par celles-ci et par les influences idéationnelles internationalesThe dichotomy “free trade versus protection” structures the analysis of trade policy in the textbooks of international trade. By analyzing the respective impacts of free trade and protection policies on resources allocation and well-being, the standard models, first and foremost the HOS model, conclude on the Pareto optimality of free trade. The normative requirement is then that all countries should pursue a policy of free exchange to get the prices right. However, empirical studies highlight the shift of the normative prescription: trade policies practiced include, in varying proportions between countries, between industries and between goods, measures aimed, simultaneously and selectively, export promotion, import substitution and the creation of easier access to imports. Therefore, policies followed are neither free trade nor strictly protectionist, but mixed a priori. This observation led to the development of models analyzing the effects on the general equilibrium of the application of various instruments of trade policy, and specifying the various potential forms of this policy. In particular, it is explained that the mixed trade policy is a true policy alternative. Selective interventions are then justified by the presence of dynamic comparative advantages that determine and guide interventions towards specific industries oriented towards the domestic market and / or the international one. But the theoretical basis enjoyed by mixed trade policy does not help to understand the political process through which this policy is chosen. It does not open the black box to penetrate the nucleus of political choices. This is what political economy can achieve. The theoretical explanation of the object "mixed trade policy" is at the crossroads of two approaches constituting the political economy of protection: society-centered approach and State-centered approach. While the first approach explains that politics is shaped by the interests and preferences of the most powerful private actors (or groups of) present on the national territory, the latter considers that the policy is a function of political institutions and political actors who seek to satisfy their interest and preference given national and international constraints they face. The mixed trade policy can be analyzed from different perspectives as endogenous determinants that intends to promote. Ultimately, the mixed trade policy is a political and institutional compromise between actors with heterogeneous preferences, which is partially undermined by international political constraints and ideational influences. The institutional and political compromise result from the division of the government induced by an unequal distribution of power of decision (based on political institutions) between veto players (composite actor having a veto in the process of political decision-making), and the heterogeneity of their preferences. The policy chosen, and associated institutions, must satisfy the interest of each veto player, implying compensatory measures and taking into account the institutional legacy. Not without resistance, the flexibility with which mixed trade policy can be used is reduced by the international political constraints and / or, upstream, the internal political balance in the structure of domestic preferences changed by them and by the international ideational influences

Full textAbstract:
It has been suggested that psychosocial stress influences situational fluctuations of tic frequency. However, evidence from experimental studies is lacking. The current study investigated the effects of the Trier Social Stress Test (TSST-C) on tic frequency in 31 children and adolescents with tic disorders. A relaxation and a concentration situation served as control conditions. Patients were asked either to suppress their tics or to “tic freely.” Physiological measures of stress were measured throughout the experiment. The TSST-C elicited a clear stress response with elevated levels of saliva cortisol, increased heart rate, and a larger number of skin conductance responses. During relaxation and concentration, the instruction to suppress tics reduced the number of tics, whereas during stress, the number of tics was low, regardless of the given instruction. Our study suggests that the stress might result in a situational decrease of tic frequency.

An elaboration on how to construct a spillway for closure for a large tailings pond completely enclosed by embankments, leading to a situation where construction in bedrock is not possible is presented with the following conclusion. A stepped spillway arrangement constructed with granite blocks will require of large blocks for being stable, and will require of filters that are not always considered functional in long-term perspective. It is presented an analysis of the overall stability of the structure proposed and of the stability of its individual blocks. In addition, it will be impossible to design a vegetated channel that remains stable, without silting and without erosion, over thousand years without maintenance.

Full textAbstract:
Whole grains are an increasingly popular health food in America. However, shelf life of whole grains is compromised due to the presence of lipoxygenases in the bran and germ, which lead to rancidity and generation of oxidative byproducts. These byproducts reduce sensory quality and may have a degradative effect on vitamins in whole grain products. The purpose of this study was to determine the degree of lipid and vitamin degradation during long-term storage of three whole grains: whole wheat flour, brown rice, and rolled oats. We also examined vitamin loss after cooking to determine if oxidative byproducts had an effect on vitamins during typical household cooking. Whole wheat flour, brown rice, and rolled oats were stored for 12 months and periodically analyzed for conjugated dienes, free fatty acids, tocopherols, thiamin, and riboflavin. Whole wheat bread, steamed brown rice, and oat porridge were made from samples stored for 0 months and 12 months and were analyzed for thiamin and riboflavin. Conjugated dienes increased significantly only in rolled oats, while tocopherols decreased significantly in whole wheat flour and rolled oats and insignificantly in brown rice. Free fatty acids increased significantly in whole wheat flour and brown rice. Thiamin and riboflavin were stable in raw stored grains and cooked products made from stored grains with the exception of brown rice, in which we observed a significant decrease in thiamin after 12-month storage and cooking. These results suggest whole wheat flour, brown rice, and rolled oats experience significant lipid and tocopherol degradation, but it does not appear to affect thiamin and riboflavin in raw stored products. Cooking appears to cause degradation of thiamin after storage of brown rice, but thiamin and riboflavin were otherwise stable in these whole grains.

Full textAbstract:
Thesis (M. Tech. (Biomedical Technology)) -- Central University of technology, Free State, 2013Electromagnetic fields are present wherever electricity is created. The frequency range of these electromagnetic fields is from extremely low to extremely high. The fields present in domestic areas fall within the extremely low frequency range. These fields are created by domestic electrical appliances and telecommunication. There has been much debate on the effect of exposure to these fields on human health. Research has not yet been able to prove adverse effect of these fields on human health. In fact, the benefits of magneto therapy has been recognized and used for several decades. Recently a specific electromagnetic signal has been under investigation for its ability to stimulate the immune response. This signal is produced by a patented generator, called Immunent Activator. Studies performed with the Immunent Activator signal on farm animals revealed increased feed conversion and decreased intestinal lesions of animals with intestinal infections. Most of the research was performed on fish and fowls and evidence of similar findings in mammals is lacking. In the current study, mice were exposed to the Immunent BV signal for seven days, after which immune cell counts were performed and compared to the immune cell counts of a control group of mice which received no electromagnetic exposure. It was found that the T-lymphocyte population of immune cells in the exposed group of mice was statistically significantly higher than that of the control group. The neutrophil count was statistically significantly lower in the exposed group compared to the control group. These findings revealed evidence of immune stimulation in the mice which were exposed to the Immunent Activator signal. Suggestions for further research could be made with regard to specific mechanisms of immune stimulation. The findings of this and other related studies hold benefits for the farming and health industry.
