Le but de la présente étude est de comprendre la situation écobiologique et la dynamique des populations piscicoles dans ce réservoir, notamment chez l'espèce Oreochromis mossambicus qui y domine. Nous avons divisé cette présentation de la façon suivante : Une première partie évoque le réservoir Bening où nous avons travaillé puis, quelques réservoirs indonésiens qui ont été bien étudiés, et dit comment on les a aménagés. Nous avons essayé de comparer entre eux ces différents réservoirs. La communauté piscicole est présentée ensuite. La troisième partie concerne l'écobiologie chez quelques espèces. On y trouvera la description de la reproduction et du régime alimentaire. Enfin, nous abordons la dynamique des populations, particulièrement la croissance et la mortalité chez certaines espèces. Dans une conclusion générale, nous proposons un aménagement piscicole adapté au réservoir Bening.

Resumo: A psoríase é uma doença cutânea crônica, cuja condição bucal mais freqüentemente associada é a língua geográfica. Fatores genéticos e ambientais estão relacionados com as mesmas. A descrição destes fatores mostra a importância do estudo da herdabilidade para determinação quantitativa da influência do genótipo e do ambiente. Este trabalho foi realizado com o objetivo de estudar a herdabilidade da psoríase cutânea e língua geográfica, através do estudo de genealogias de famílias com portadores destas condições. Foram estudados 356 heredogramas de pacientes com estas doenças, a partir de prontuários de um ambulatório dermatológico, independente da idade, gênero e grupo étnico. A amostra foi constituída por 128 propósitos com psoríase cutânea, do tipo vulgar e 257 língua geográfica. Os propósitos com psoríase cutânea apresentavam ou não simultaneidade de língua geográfica e os propósitos com língua geográfica apresentavam ou não simultaneidade de psoríase cutânea. Para a determinação da herdabilidade, utilizou-se o método de Falconer. Este método foi desenvolvido em genética quantitativa, para avaliar o comportamento de características de limiar, aplicado para dados da incidência das doenças, a fim de responder a questão relativa à importância da herança e do ambiente no desenvolvimento das mesmas. A partir dos resultados obtidos destas análises, constatamos que: a) a herdabilidade dos pais em famílias de portadores de psoríase foi de 89,2%, sendo esta considerada alta; b) o mesmo foi observado com relação aos filhos (86,8%) e filhas (84,4%) do propósito; c) verificou-se herdabilidade maior nos grupos de irmãos e irmãs que nos grupos dos pais do propósito, sendo todas as herdabilidades consideradas altas; d) as herdabilidades das irmãs (97%) e irmãos (98%) foram as maiores obtidas, sendo muito semelhantes entre si e maiores do que a dos pais do propósito (89,2%); e) verificou-se a correlação entre filhos/propósito (86,8%) e filhas/propósito (84,4%), ambas com herdabilidade alta e muito semelhante; f) com relação à língua geográfica, observou-se que o valor da herdabilidade filhos/propósito (80,2%) foi maior que a dos pais/propósito (41,6%), sendo o mesmo verificado para a herdabilidade filhas/propósito (68,6%) que na herdabilidade pais/propósito (41,6%); g) a herdabilidade irmãos/propósito (56,8%) foi maior que o valor para pais/propósito (41,6%) e irmãs/propósito (41,6%); h) na comparação entre as herdabilidades filhos/propósito (80,2%) e filhas/propósito (68,6%), observamos que esta foi maior na primeira que na segunda; i) observou-se herdabilidade maior na relação irmãos/propósito (56,8%) que na irmãs/propósito (41,6%); j) o cálculo da herdabilidade total para o grupo com psoríase indicou uma herdabilidade alta (92,1%); k) com relação ao grupo com língua geográfica, também se observou uma herdabilidade alta (51,5%). A partir destes dados, conclui-se que tanto na psoríase, quanto na língua geográfica existe um fator genético determinante
Abstract: Psoriasis is a chronic cutaneous disease whose oral condition is more frequently associated to benign migratory glossitis. Aspects as epidemiological association, basic lesions and microscopic characteristics similarly support the idea that benign migratory glossitis is the true form of oral psoriasis. This study was done having the objective of study the heritability to cutaneous psoriasis and benign migratory glossitis through the genealogy of family with holder these diseases. Were studied 356 heredograms of patients from the records of the dermatological ambulatory, independently of age, gender or ethnic group. The sample was made up of 128 propositi with cutaneous psoriasis and 257 with benign migratory glossitis. The patients suffering from cutaneous psoriasis presented benign migratory glossitis simultaneous or not and the patients of benign migratory glossitis group presented or not psoriasis simultaneously. To determination of heritability were applied Falconer¿s methods. This method was developed in quantitative genetics to analyze the behavior of threshold characteristics. It was applied to date of the incidence of the diseases, so as to answer the question about the role of the inheritance and environmental factors in development the psoriasis and benign migratory glossitis. The following constations were taking from the observed results: a) the heritability of parents in families with patients suffering from cutaneous psoriasis was 89,2%, being considered high; b) high heritability was observed to sons (86,8%) and daughters (84,4%) from propositi; c) it was verified heritability higher in groups of brothers and sisters than groups of parents from propositi, that showed high heritabilities; d) the heritabities of sisters (97%) and brothers (98%) were the higher obtained, and very similar among these and higher than parents from propositi (89,2%); e) it was verified the correlation among sons/propositi (86,8%) and daughters/propositi (84,4%), both having high heritability and very similar; f) beside to benign migratory glossitis, observed that value to heritability sons/propositi (80,2%) was high than parents/propositi (41,6%), being the same verified beside to heritability daughters/propositi (68,6%) that to heritability parents/propositi (41,6%); g) the heritability brothers/propositi (56,8%) was higher than the value to parents/propositi (41,6%) and sisters/propositi (41,6%); h) beside the heritabilities sons/propositi (80,2%) and daughters/propositi (68,6%), it was observed that the heritability was higher in first than second; i) it was observed heritability higher beside brothers/propositi (56,8%) than sisters/propositi (41,6%); j) the total heritability to group with cutaneous psoriasis indicated high heritability (92,6%); k) comparing to group with benign migratory glossitis was also observed a high heritability (54,8%). These data allow the conclusion that, both psoriasis and benign migratory glossitis have a determinant genetic factor

Pełny tekst źródłaStreszczenie:
Horseshoes are manufactured metal plates developed in an extensive assortment of materials and shapes and their main function is to protect the horse’s hooves and legs against abrasion and rupture. After a certain period of time the horseshoes are lost, worn out, or the hoof needs to be treated. Horseshoeing is a repetitive time consuming process for the farrier who has to heat the horseshoe inside a forge until it reaches the required temperature and shape it with a hammer until it fits perfectly to the horses’ hoof. The main goal of this project is to develop a horseshoe bending machine able to shape the horseshoe so its shape fits perfectly the horse’s hoof. The calculation of the bending force needed to be applied to the horseshoe in order to provoke a plastic deformation will be done with Euler-Bernoulli beam theory. The bending force is then used to design and dimension each element of the bending mechanism so that it may be able to resist the stresses and prevent the parts from collapsing during its working life span. A study of the springback effect will be done followed by the analysis of the hertzian contact stresses between the rollers and the horseshoe. In addition, a clamping system is selected to constrain the movements of the horseshoe during the bending process. This machine will reduce the final user’s horse maintenance costs at the same time that makes the fitting process easier and less demanding, which will improve the farrier’s working life span and quality.

Benign prostatahyperplasi (BPH) är ett tillstånd som drabbar nästintill samtliga män över 80 år och vilket medför urologiska besvär som kan ha inverkan på livs¬kvaliteten och det dagliga livet. Syftet med denna litteraturstudie var att redogöra för hur män med benign prostatahyperplasi upplever sitt dagliga liv samt hur deras livskvalitet påverkas. En litteraturstudie gjordes utifrån ett systematiskt tillväga¬gångssätt. Litteratursökningen utfördes i databaserna Cinahl, PsycInfo, PubMed samt The Cochrane Library. Både kvantitativa och kvalitativa studier inkluderades vilka kvalitetsgranskades av båda författarna oberoende av varandra med hjälp av ett modifierat granskningsprotokoll. Resultatet visar på att män med BPH har en störd sömn på grund av nykturi, begränsar sitt sociala liv och upplever genans över de urologiska symtomen och en negativ påverkan på det sexuella samlivet. Män med BPH tycks också utveckla copingstrategier för att bemästra sin vardag som att t ex reducera vätskeintaget, prata om besvären och acceptera tillståndet. Det verkar också vara vanligt förekommande att livskvaliteten hos män med BPH är sämre än hos män utan BPH. Fler studier med både kvalitativ och kvantitativ metodansats behövs för att finna en djupare förståelse för män med BPH och för att stärka evidensen avseende livskvalitet och dagligt liv.Benign prostatic hyperplasia (BPH) is a condition which causes urology bother that might have an impact on quality of life and daily living in almost all men over the age 80. The aim of this study was to report on how men with benign prostatic hyperplasia experiencing their daily lives and how their quality of life is affected. A systematic review was made in accordance to a systematic procedure. The literature searching was made in the databases CINAHL, PsycInfo, PubMed and The Cochrane Library. Both quantitative and qualitative studies were included and the quality was assessed by both authors independently of each other using a modified audit protocol. The results show that men with BPH have disturbed sleep due to nocturia, limiting their social lives and experiencing embarrassment over the urological symptoms and a negative impact on the sexual life. Men with BPH also seems to develop coping strategies to overcome their daily lives such as reducing fluid intake, talk about the complaint and accept the condition. It also seems that it is more common for men with BPH to rank their quality of life lower than men without BPH. More studies using both qualitative and quantitative approach are needed to find a deeper understanding of men with BPH and to strengthen evidences about quality of life and daily life.

Problem Investigated: A multitude of benign disorders affect the anorectal complex often resulting in significant morbidity. For many of these conditions the pathophysiology and clinical management continue to be debated. This is particularly so for anal fissures, anal incontinence and pelvic floor dysfunction. Procedures Followed: A series of clinical trials was performed. Anal Fissure: Two current management regimes for chronic anal fissure, Glyceryl Trinitrate and Botulinum Toxin, were prospectively assessed for manometric and clinical outcome. A new treatment regime, inducible nitric oxide, was prospectively assessed in an animal model and a new manometric observation in anal fissure patients, the Fast Wave, was validated. Anal Incontinence: The magnitude of the problem and the relative role of several previously identified risk factors was assessed from a manometric data-base. The impact of a standard treatment for Crohn???s disease, the seton, on anal continence was assessed via a retrospective cohort study. The long-term outcome of dynamic graciloplasty and re-do anal sphincter repair, two previously accepted treatments for anal incontinence, were also assessed retrospectively. A new intervention for treating anal incontinence, the magnetic ???Chair???, was prospectively trialed in incontinent patients. Pelvic Floor Dysfunction: A new treatment option for rectocoele, the laparoscopic repair, was compared with an accepted treatment option, the transanal repair via a matched cohort study. A further group of patients with multiple symptoms of pelvic floor dysfunction undergoing the same laparoscopic technique were then prospectively assessed for functional outcome across the pelvic floor compartments. General Results: Anal Fissure; The manometric effects of both glyceryl trinitrate and botulinum toxin, demonstrated in this thesis would imply that their mode of impact on the anal sphincter is other than that of anal pressure reduction. Fissure healing is dependent upon the pre-treatment anal resting pressure and fissure grade, not anal pressures following treatment. Inducible nitric oxide does not increase nitrate levels in the rat internal anal sphincter. A new manometric wave form in the hypertonic internal anal sphincter, the Fast Wave, has been validated. Faecal Incontinence; Faecal incontinence is multi-factorial. However, obstetric birth injuries are the most significant factor predisposing to faecal incontinence following age. Furthermore current government policies are failing to address the problem. The dynamic graciloplasty provides symptomatic long-term relief in only 16 percent of patients and results in significant co-morbidity in most patients. Re-do anal sphincter repair provides relief in 60 percent of patients without further side effects. The use of a seton in Crohn???s perianal disease prevents deterioration of patient continence. Extracorporeal magnetic stimulation, the Chair, may provide significant relief for patients with faecal incontinence. Pelvic Floor Dysfunction: The laparoscopic posterior compartment repair provides relief of bowel symptoms in 31 percent of patients. This does not compare favourably with the transanal long-term symptomatic improvement of 67 percent. The results of the laparoscopic pelvic floor repair in patients with multiple symptoms of pelvic floor dysfunction is disappointing, particularly for bowel and bladder symptom improvement. Major Conclusions: This thesis questions the accepted pathophysiology of anal fissure, highlights the long-term implications of obstetric childbirth injuries on faecal continence and raises concerns about current management strategies for faecal incontinence and pelvic floor dysfunction.

Virtual reality (VR), an emergent technology, affords experiential content delivery in education by evoking emotive responses in users, which can be prohibitive via traditional media. This thesis explores VR for the development of grit – passion and perseverance, which are essential characteristics in education and long-term success. The research proposes design strategies to stimulate senses for emotional engagement and a physiological response. In the project, two interactive environments position the user in emotional states to build passion and perseverance. To develop passion, the virtual world is designed to engage in creativity using 3D-spatial audio and visual effects. In contrast, to build perseverance users are exposed to a challenging environment that requires them to overcome and positively associate frustration with growth. This thesis demonstrates the potential of design for higher sense-stimulation applied through VR in education.

Aquesta Tesi Doctoral es va centrar en l’estudi de les alteracions lligades a canvis en el contingut intraluminal i en l’expressió i localització de citoquines i quimoquines a la pròstata de rates sanes i afectades per hiperplàsia prostàtica benigna associada amb l’edat (HPB). Els resultats van mostrar que l’aparició de la HPB era paral·lela a un increment en un contingut intraductal PAS+. Aquest contingut estava format majoritàriament per polisacàrids poc ramificats, amb presència majoritària d’enllaços α-1,4 glucosídics. D’altra banda, també es va observar un increment en l’expressió intracel·lular de l’enzima glicogen sintasa en algunes cèl·lules ductals, el que suggereix una alteració global en el metabolisme del glicogen ductal. L’estudi d’expressió de citoquines i quimoquines mitjançant mini-arrays va mostrar que la instauració de la pubertat està cronològicament relacionada amb una disminució generalitzada de l’expressió prostàtica d’un gran nombre d’aquests factors, malgrat que alguns d’ells tornen a incrementar els seus nivells a partir dels 6 mesos de vida. A més a més, l’aparició de HPB fou paral·lela a un increment de l’expressió prostàtica d’un grup reduït de citoquines y quimoquines, entre las que destaquen el PDGF, el TIMP-1 i el VEGF. Quan es van comparar el panell de expressió prostàtic i sèric de citoquines i quimioquines en rates de diferents grups d’edat pràcticament no es van observar proteïnes que patissin variacions equivalents, essent-ne l’única excepció el VEGF. Finalment, centránt-se en el VEGF, es va poder determinar que l’incremento observat en la seva expressió tant mitjançant miniarrays como per Western blotting es relacionava amb l’aparició de nivells significatius citoplàsmics de VEGF en les cèl·lules prostàtiques, apareixent també un increment en el processament post-traduccional de la proteïna a través del seu pas per l’aparell de Golgi. Aquestes alteracions van ser simultànies amb un increment significatiu en l’expressió del receptor de VEGF. Per tant,, como a conclusió d’aquests resultats es podria inferir que l’inici de la HPB està més relacionat amb canvis en els processos de angiogènesi prostàtica que en mecanismes inmunitaris ‘per se’. Endemés, els resultats també van suggerir la possibilitat d’estudiar el patró d’expressió sèrica de VEGF com un possible marcador de HPB en rata.Esta Tesis Doctoral se centró en el estudio de alteraciones ligadas a cambios en el contenido intraluminal y en la expresión y localización de citoquinas y quimoquinas en la próstata de ratas sanas y afectadas por hiperplasia prostática benigna asociada con la edad (HPB). Los resultados mostraron que la aparición de la HPB era paralela a un incremento en un contenido intraductal PAS+. Este contenido estaba formado mayoritariamente por polisacáridos poco ramificados, con presencia mayoritaria de enlaces α-1,4 glucosídicos. Por otra parte, también se observó un incremento en la expresión intracelular del enzima glucógeno sintasa en algunas células ductales, lo que sugiere una alteración global en el metabolismo del glucógeno ductal. El estudio de expresión de citoquinas y quimoquinas mediante mini-arrays mostró que la instauración de la pubertad está cronológicamente relacionada con una disminución generalizada en la expresión prostática de un gran número de estos factores, si bien algunas de estas proteínas vuelven a incrementar sus niveles a partir de los 6 meses de vida. Por otra parte, la aparición de HPB fue paralela a un incremento en la expresión prostática de un grupo reducido de citoquinas y quimoquinas, entre las que destacan el PDGF, el TIMP-1 y el VEGF. Al comparar el panel de expresión prostático y sérico de citoquinas y quimioquinas en ratas de diferentes grupos de edad apenas se observaron proteínas que sufrieran variaciones equivalentes, siendo la única excepción el VEGF. Finalmente, centrándonos en el VEGF, se pudo determinar que el incremento observado en su expresión tanto mediante miniarrays como por Western blotting se relacionaba con la aparición de niveles significativos citoplásmicos de VEGF en las células prostáticas, apareciendo asimismo un incremento en el procesamiento post-traduccional de la proteína a través de su paso por el aparato de Golgi. Estas alteraciones fueron concomitantes con un incremento significativo en la expresión del receptor de VEGF. Así pues, como conclusión de estos resultados se podría inferir que el inicio de la HPB está más relacionado con cambios en los procesos de angiogénesis prostática que en mecanismos inmunitarios ‘per se’. Además, los resultados también sugirieron la posibilidad de estudiar el patrón de expresión sérica de VEGF como un posible marcador de HPB en rata.
This PhD dissertation was centred on the study of the alterations in both the intra-luminal content and the cytokines and chemokines expression in prostates from healthy rats and also from individuals affected by age-related benign prostastic hyperplasia (BPH). Ours results showed that the onset of BPH was concomitant with an increase in the PAS+ intraductal prostatic content. This content was mainly composed by low branched polysaccharides, which showed high levels of α-1,4 glycosydic bonds. Otherwise an increase in the intracellular glycogen synthase expression was also observed in some ductal cells. This would suggest a putative alteration of the whole glycogen metabolism in prostate ducts associated with the appearance of the BPH. The analysis of the expression of prostate cytokines and chemokines through a miniarray system showed that the onset of puberty was parallel to an overall decrease in the expresión of the analyzed factors, although there was a partial recovery from age 6-months old onwards. The appearance of BPH was also parallel to an increase of a low number cytokines/chemokines, namely PDGF, TIMP-1 and VEGF. When comparing the expression panel the analyzed cytokines and chemokines of prostate extracts against those from blood serum only the VEGF underwent parallel changes in both samples. Finally, the observed BPH-concomitant increase of prostate VEGF expression, which was confirmed through both miniarrays and Western blotting, was parallel with the appearance of significant intracytoplasmic levels of VEGF that were accompanied with an increase in the post-translational processing of this protein through the Golgi apparatus. These changes were concomitant with a significant increase in the expression of the ductal VEGF receptor. In this manner, as a conclusion, the obtained results would suggest that the BPH onset in rats would be more related with alterations in the regulation of prostate angiogenesis than in the launching of intrinsic immunitary reactions. Furthermore, results also suggest the possibility to utilize VEGF serum levels as an useful putative marker for BPH in rat.

Steady-state and transient surface photovoltages in undoped GaN are studied in various environments (air, nitrogen, oxygen, vacuum) at room temperature and 400 K with a Kelvin probe attached to an optical cryostat. The results are explained within a phenomenological model accounting for the accumulation of photo-generated holes at the surface, capture of free electrons from the bulk over the near-surface potential barrier, and emission of electrons from surface states into the bulk. Mechanisms of surface photovoltage are discussed in detail. Photoadsorption and photodesorption of negatively charged species will either increase or decrease the surface potential and thus band bending. Oxygen is the assumed species responsible for the SPV changes in air ambient during continuous UV illumination. This variation in SPV will be confirmed with photoluminescence measurements.

Bakgrund: Benigna gynekologiska åkommor är något som påverkar kvinnors hälsa och livskvalitet. Hysterektomi är den andra vanligaste operationen inom gynekologin och kvinnor som är drabbade av benigna gynekologiska åkommor kan genomgå en hysterektomi som behandling. Livskvaliteten påverkas även av att genomgå en hysterektomi. Syfte: Att beskriva livskvaliteten efter genomgången hysterektomi för kvinnor som drabbats av benigna gynekologiska åkommor. Metod: En litteraturöversikt baserad på 14 artiklar har utförts. Artiklarna är publicerade mellan 2000-2016 och är från olika länder. Sökningar har gjorts i databaserna PubMed, Cinahl, Web of Science och psykINFO. Resultat: Resultatet presenteras i sju kategorier där undertexten handlar om kvinnors livskvalitet efter hysterektomi. Kategorierna presenterar livskvalitetens olika aspekter och om förbättring eller försämring i symtom kan ses. Kategorierna är: smärta och blödning kan kvarstå, för tidig menopaus inträder, det sexuella samlivet, förlust av fertilitet, faktorer som kan påverka livskvaliteten relaterat till total hysterektomi, psykiska upplevelser av att ha genomgått en hysterektomi och informationsbehov. Slutsats: Livskvaliteten förbättras för de allra flesta kvinnor efter genomgången hysterektomi. Vissa symtom kan kvarstå, även om de blir förbättrade.Background: Benign gynecologic condition are something that affects women's health and quality of life. Hysterectomy is the second most common surgery in gynecology and women who suffer from benign condition may undergo a hysterectomy as treatment. The quality of life is also affected by undergoing a hysterectomy. Aim: To describe the quality of life after a hysterectomy for women who suffers from benign gynecologic condition. Method: A literature review based on 14 articles have been performed. The articles are published between 2000-2016 and are from different countries. Searches have been made in the databases PubMed, CINAHL, Web of Science and psykINFO. Results: The result are presented in seven categories and the sub-texts describes women's quality of life after hysterectomy. The results present quality of life in different aspects, and if the symptoms gets worse or improves. The categories are: early menopaus, the sexual life, loss of infertility, factors that affects the quality of life related to total hysterectomy, psychological experience of undergoing hysterectomy and information needs. Conclusion: Quality of life were improved for most women after the hysterectomy. Some symptoms may persist, although the most were improved.

Câncer é um conjunto de alterações celulares, que leva a uma divisão celular sem controle, podendo invadir tecidos adjacentes através da circulação sanguínea e do sistema linfático. O Câncer de Próstata (CP) é o segundo tumor mais comum entre a população masculina, e é considerado o câncer da terceira idade. A carcinogênese é um mecanismo complexo no qual ocorre mudanças na expressão de proteínas e glicoconjugados. Glicosilação é mediada por glicosiltransferases, enzimas que tem função de inserir resíduos de carboidratos específicos, e é um dos mais importantes processos biológicos pós-tradução de modificações na estrutura final e função de lipídios e proteínas. As fucosiltransferases (FUT) participam da transferência de resíduos de L-fucose, um sacarídeo associado ao câncer e a processos inflamatórios, da GDP-L-fucose. Neste estudo objetivou-se avaliar a expressão dos genes FUT3 e FUT6 através da Imunohistoquímica em Adenocarcinoma Prostático e Hiperplasia Prostática Benigna correlacionando com o padrão de expressão de L-fucose empregando a histoquímica com as lectinas UEA-I (Ulex europaeus) e LTA (Lotus tetragonolobus). As enzimas FUT3 e FUT6 apresentaram-se com uma alta expressão tanto no Adenocarcinoma Prostático como na Hiperplasia Benigna Prostática, principalmente a FUT 6. Os resultados da histoquímica com lectinas mostraram uma baixa distribuição/accessibilidade de L-fucose. Sugere-se que, as enzimas FUT3 e FUT6 possam representar potenciais biomarcadores para avaliar alterações benignas e malignas prostáticas refletindo uma variação no perfil de L-fucose nestes tumores que podem estar associados às suas características biológicas.
Cancer is a set of cellular changes, leading to uncontrolled cell division that may invade surrounding tissues via bloodstream and lymphatic system. Prostate Cancer (PC) is the second most common tumor in men and is considered the cancer of the elderly. Carcinogenesis is a complex mechanism in which changes occur in the expression of proteins and glycoconjugates where glycosylation plays key roles since modulates the carbohydrate moieties in glycoconjugates being one of the most important biological processes of posttranslational modifications in the final structure and function of lipids and proteins. Fucosyltransferases (FUTs) are enzymes that catalyze the transfer of the L-fucose residues, a saccharide which has been linked to cancer and inflammation features, from GDP-Fuc. This study the objective to evaluate the expression of genes FUT 3 and FUT 6 by immunohistochemistry in Prostatic Adenocarcinoma and Benign Prostatic Hyperplasia and to correlates with the expression pattern of L-fucose using lectin histochemistry with UEA-I (Ulex europaeus) and LTA (Lotus tetragonolobus). FUT3 and FUT6 showed a high expression in both prostatic tissues, especially FUT6. The results of lectin histochemistry showed a low distribution/accessibility of L-fucose residues. It is suggested that FUT3 and FUT6 may represent potential biomarkers to evaluate benign and malignant alterations in prostate reflecting a variation in the profile of L-fucose residues in these tumors which can be associated to their biological features.

Benign prostatic hypertrophy (BPH) is a very common disease among men aged 50 and its economic burden on health services continues to grow. The advocation for adopting new screening procedure for BPH begins to emerge. However, a new proposal for screening should be under careful scrutiny and ineffective and inappropriate screening must be avoided. A prospective cohort study has been launched to study the frequency, distribution, and natural history of BPH in two well-defined small communities in Central Scotland. Using the data from the cohort study, the hypothesis that a BPH screening programme justifies the stringent criteria set by Wilson and Jungner (1968) to evaluate any proposed programme, could be tested. The hypothesis has to be rejected after taking all the criteria into account. BPH was a major health problem among apparently well middle-age and elderly men in the community. It imposed significant interference in men's daily routine as well as influenced on their psychological general well-being. Although there was a detectable asymptomatic stage, the natural history of BPH from asymptomatic to a clinical stage was not clear. Because of the obscurity of the natural history, the optimum interval between repeated screens of a continuous screening process was unknown. The facilities for diagnosis and treatment could not be met by the present health services. The economic implications of a screening programme could be enormous, though a systemic analysis to evaluate the worthwhileness of the screening programme in economic terms was not conducted.

A Reabilitação Vestibular (RV) é um programa de tratamento realizado por exercícios, associado a um conjunto de medidas relacionadas à mudança de hábitos e esclarecimentos sobre os sintomas associados à alteração do equilíbrio. É um método de terapia fisiológico, inócuo e coerente, que pretende trabalhar o paciente vertiginoso aliviando os sintomas e aumentando seu limiar de sensibilidade para a vertigem. A Vertigem Postural Paroxística Benigna (VPPB) é a mais comum das vestibulopatias periféricas em adultos, principalmente em idosos do sexo feminino, apresentando como etiologia mais comum a degeneração da mácula utricular. Nos idosos, caracteriza-se por tontura rotatória e nistagmo posicional à mudança de posição da cabeça ou por determinada posição do corpo e, como conseqüência, pode ocorrer quedas e limitações na qualidade de vida dos mesmos, tornando-os limitados físico e emocionalmente. O presente estudo teve como objetivo avaliar prospetivamente a Reabilitação Vestibular como tratamento da VPPB com acometimento de canal semicircular posterior e seu efeito na qualidade de vida em indivíduos idosos. Participaram do estudo 23 voluntários com hipótese diagnóstica otorrinolaringológica de VPPB de canal semicircular posterior por ductolitíase, com faixa etária entre 60 e 91 anos, com média de 70,69 anos e desvio padrão de 9,24. Quanto ao gênero 17 (73,9%) eram do sexo feminino e 6 (26,1%) do masculino. No tratamento da VPPB por meio da reabilitação vestibular em 17 (73,9%) dos voluntários, utilizou-se a manobra de Epley; 6 (26,08%) com manobra de Epley associada ao exercício de Brandt e Daroff . O tempo de tratamento variou de 2 a 6 semanas. Aplicou-se um questionário (Dizziness Handicap Inventory - DHI brasileiro) pré e pós RV para quantificar a tontura quanto aos aspectos: físico, emocional, funcional e geral. Quanto ao aspecto físico, emocional, funcional e geral observou-se diferença estatisticamente significativa (p<0,0001) entre os escores pré e pós RV. Concluímos que os escores dos aspectos avaliados no DHI brasileiro melhoraram após intervenção fonoaudiológica pela RV nos pacientes com VPPB de canal semicircular posterior, havendo um incremento na qualidade de vida dos voluntários estudados.Vestibular rehabilitation is a treatment?s program based on exercises, associated with a factor?s collection related to changing habits and guidance about symptoms associates to unbalance. It is harmless, coherent and physiologic therapy method that intends to work the dizzy patient, relieving the symptoms and increasing his vertigo?s threshold. The Benign Paroxysmal Positional Vertigo is the one most frequent adult?s pathologies of the peripheral vestibular?s system. It is caused by the utricle?s degeneration. In aged people, is characterize by vertigo and positional nystagmus provoked by certain cephalic movements or body movements and, as sequelae, can take to falls and life quality restriction, physical and emotional. This study?s purpose was evaluate the Vestibular Rehabilitation in posterior canal?s BPPV?s treatment and its effect in the elderly life?s quality. Twenty three volunteers with BPPV ?s posterior canal?s canalith diagnoses pointed out by otorhinolaryngologist, aged between sixty to ninety one years old, average of 70,69 years and deviation of 9,24. Seventeen volunteers (73,9%) were female and six (26,1%) were male. In BPPV?s treatment by vestibular rehabilitation, thirteen (56,52%) were submitted to Epley maneuver, six (26,08%) used the Epley maneuver associated to Brandt- Daroff exercises and four patients (17,39%) were submitted only to the Brandt- Daroff exercises. The treatment?s time lasted from 2 to 6 weeks. A questionnaire (Dizziness Handicap Inventory Portuguese- DHI Portuguese) was used in order to dizziness quantity in the physical, emotional, functional and general aspects, which was observed a significant statistical difference (p<0,001) between the scores previous and after Vestibular Rehabilitation. Concluding that the aspects? scores evaluated improved after Vestibular Rehabilitation therapy in the posterior canal?s BPPV?s patients, occurring an improvement in volunteers? life quality.

Plastic deformation of tubes can be achieved in numerous ways. One of the most useful type is CNC tube bending machines which is used in many industries such as aerospace, automotive, HVAC systems and so on. It is important that all components of system should mate properly after producing and because of this bend shaping requires sensitive operation on each components to ensure regularity of production processes with high quality end-product. Thus, the CNC tube bending industry to become widespread. However it brings some troubleshooting like wrinkling, springback, breakage and ovalisation. This failures depends on geometry of the material such as bending radius, tube thickness and also friction factor between dies and the tube. Effects of all parameters should be examined before generating the theory for a best solution. Therefore, prediction of the required moment for the proper bending process with low cost and shortened production time is needed. All of these requirements can be achieved through a C++ form application program.

Pełny tekst źródłaStreszczenie:
Les structures de type gridshell élastique permettent de réaliser des enveloppes courbes par la déformation réversible d’une grille structurelle régulière initialement plane. Cette capacité à “former la forme” de façon efficiente prend tout son sens dans le contexte actuel où, d’une part la forme s’impose comme une composante prédominante de l’architecture moderne, et d’autre partl’enveloppe s’affirme comme le lieu névralgique de la performance des bâtiments. Fruit des recherches de l’architecte et ingénieur allemand Frei Otto dans les années 1960, elles ont été rendues populaires par la construction de la Multihalle de Mannheim en 1975. Cependant, en dépit de leur potentiel, très peu de projets de ce type ont vu le jour suite à cette réalisation emblématique qui en a pourtant démontré la faisabilité à grande échelle. Et pour cause, les moyens engagés à l’époque ne sauraient assurer la reproductibilité de cette expérience dans un contexte plus classique de projet, notamment sur le plan économique. Par ailleurs, les techniques et les méthodes développées alors sont pour la plus part tombées en désuétude ou reposent sur des disciplines scientifiques qui ont considérablement évoluées. Des matériaux nouveaux, composites, ont vu le jour. Ils repoussent les limitations intrinsèques des matériaux usuels tel que le bois et offrent des performances techniques bien plus intéressantes pour ce type d’application. Enfin, notons que le cadre réglementaire a lui aussi profondément muté, apportant une certaine rigidité vis-à-vis de la pénétration des innovations. Ainsi la conception des gridshells se pose-t-elle en des termes nouveaux aux architectes et ingénieurs actuels et se heurte à l’inadéquation des outils et méthodes existant. Dans cette thèse, qui marque une étape importante dans une aventure de recherche personnelle initiée en 2010, nous tentons d’embrasser la question de la conception des gridshells élastiques dans toute sa complexité, en abordant aussi bien les aspects théoriques que techniques et constructifs. Dans une première partie, nous livrons une revue approfondie de cette thématique et nous présentons de façon détaillée l’une de nos principales réalisation, la cathédrale éphémère de Créteil, construite en 2013 et toujours en service. Dans une seconde partie, nous développons un élément de poutre discret original avec un nombre minimal de degrés de liberté adapté à la modélisation de la flexion et de la torsion dans les gridshells constitués de poutres de section anisotrope. Enrichi d’un noeud fantôme, il permet de modéliser plus finement les phénomènes physiques au niveau des connexions et des appuis. Son implémentation numérique est présentée et validée sur quelques cas tests. Bien que cet élément ait été développé spécifiquement pour l’étude des gridshells élastiques, il pourra avantageusement être utilisé dans tout type de problème où la nécessité d’un calcul interactif avec des tiges élastiques prenant en compte les couplages flexion-torsion s’avère nécessaireAn elastic gridshell is a freeform structure, generally doubly curved, but formed out through the reversible deformation of a regular an initially flat structural grid. Building curved shapes that way seems to offer the best of both worlds : shell structures are amongst the most performant mechanically speaking while planar and orthogonal constructions are much more efficient and economic to produce than curved ones. This ability to “form a form” efficiently is of peculiar importance in the current context where morphology is a predominant component of modern architecture, and envelopes appear to be the neuralgic point for building performances. The concept was invented by Frei Otto, a German architect and structural engineer who devoted many years of research to gridshells. In 1975 he designed the Multihalle of Mannheim, a 7500 m2 wooden shell which demonstrated the feasibility of this technology and made it famous to a wide audience. However, despite their potential, very few projects of this kind were built after this major realization. And for good reason, the ressources committed at that time cannot guarantee the replicability of this experiment for more standard projects, especially on the economic level. Moreover, the technics and methods developed by Otto’s team in the 1960s have mostly fall into disuse or are based on disciplines that have considerably evolved. New materials, such as composite materials, have recently emerged. They go beyond the limitations of conventional materials such as timber and offer at all levels much better technical performances for this kind of application. Finally, it should be noted that the regulatory framework has also deeply changed, bringing a certain rigidity to the penetration of innovations in the building industry. Therefore, the design of gridshells arises in new terms for current architects and engineers and comes up against the inadequacy of existing tools and methods. In this thesis, which marks an important step in a personal research adventure initiated in 2010, we try to embrace the issue of the design of elastic gridshells in all its complexity, addressing both theoretical, technical and constructive aspects. In a first part, we deliver a thorough review of this topic and we present in detail one of our main achievements, the ephemeral cathedral of Créteil, built in 2013 and still in service. In a second part, we develop an original discrete beam element with a minimal number of degrees of freedom adapted to the modeling of bending and torsion inside gridshell members with anisotropic cross-section. Enriched with a ghost node, it allows to model more accurately physical phenomena that occur at connections or at supports. Its numerical implementation is presented and validated through several test cases. Although this element has been developed specifically for the study of elastic gridshells, it can advantageously be used in any type of problem where the need for an interactive computation with elastic rods taking into account flexion-torsion couplings is required

Pełny tekst źródłaStreszczenie:
Upper airway stenosis has a significant impact on the quality of life and sometimes on life itself. The incidence of this condition is likely to be increasing as survival rates following periods of ventilation on Intensive Care Units (ICUs) improve (1, 2). Paediatric laryngotracheal stenosis is a well researched discipline and treatment includes airway augmentation with rib grafts and tracheal or cricotracheal resection with end-to-end anastomosis. At the start of my research, in 2005, adult laryngotracheal stenosis was poorly researched and the treatment options were tracheostomy, tracheal resection or cricotracheal resection, each with associated morbidity and mortality. This thesis investigates the aetiology, incidence, screening and alternative treatment options, which include endoscopic techniques, for the management of acquired adult benign laryngotracheal stenosis. The commonest causes for this condition are ventilation on intensive care units and inflammatory disorders such as Wegener's granulomatosis, idiopathic subglottic stenosis and sarcoidosis. In January 2004 a prospective database was set up in the busiest airway reconstruction unit in the United Kingdom. Data was collected on all new adult patients with upper airways stenosis. At the completion of this research in January 2010, 400 patients had been entered on this database. Due to the rarity of this condition, it was not possible to design randomised trials to compare different treatment options. This thesis is an integrated series of prospective cohort studies, with the aim of developing a greater understanding of adult airway stenosis, with a particular emphasis on minimally invasive endoscopic techniques. This research has shown that 72% of patients with post-intubation airway stenosis can be treated with these minimally invasive endoscopic techniques. Effective new treatments have been devised for the management of inflammatory stenoses when the results of previous treatments had not been effective. New tools for assessing the airway and outcome measures have also been proposed.

Bakgrund: Benign prostatahyperplasi påverkar åldrande män över hela världen och en fjärdedel av alla män beräknas ha symptom till följd av sjukdomen. Vid uppkomst av symptom drabbas mannens nedre urinvägar vilket kan leda till bland annat nedre urinvägssymptom, sexuell dysfunktion och psykiska besvär vilket kan antas påverka livskvalitén. Som referensram valdes livskvalité med utgångspunkt i Världshälsoorganisationens definition och Sprangers och Schwartz modell om response shift. Syfte: Att belysa livskvalitén hos män med symptomgivande benign prostatahyperplasi. Metod: Litteraturstudie med induktiv ansats. Resultat: Resultatet visade att livskvalitén påverkas negativt av symptomen vid benign prostatahyperplasi. Graden av påverkan berodde på vilket symptom samt symptomets allvarlighetsgrad. De mest framträdande och återkommande symptomen var nocturi, akut blåstömning, smärta samt sexuell dysfunktion. Slutsats: I resultatet framkom att benign prostatahyperplasi påverkade livskvalitén negativt. Dock saknades kvalitativ forskning för att beskriva hur livskvalitén påverkades. För att få en tydlig bild av att se hur livskvalitén förändras över tid kan modellen om response shift användas och därmed kan vården på ett bra sätt främja livskvalitén hos personer drabbade av benign prostatahyperplasi.

This thesis presents two studies on elastic plates. In the first study, we discuss the choice of elastic energies for thin plates and shells, an unsettled issue with consequences for much recent modeling of soft matter. Through consideration of simple deformations of a thin body in the plane, we demonstrate that four bulk isotropic quadratic elastic theories have fundamentally different predictions with regard to bending behavior. At finite thickness, these qualitative effects persist near the limit of mid-surface isometry, and not all theories predict an isometric ground state. We discuss how certain kinematic measures that arose in early studies of rod mechanics lead to coherent definitions of stretching and bending, and promote the adoption of these quantities in the development of a covariant theory based on stretches rather than metrics.
In the second work, the effects of in-plane swelling gradients on thin, anisotropic plates are investigated. We study systems with a separation of scales between bending energy terms. Warped equilibrium shapes are described by two parameters controlling the spatial "rolling up'' and twisting of the surface. Shapes within this two-parameter space are explored, and it is shown that shapes will either be axisymmetric or twisted depending on swelling function parameters and material anisotropy. In some axisymmetric shapes, pitchfork bifurcations to twisted solutions are observed by varying these parameters. We also show that a familiar soft mode of the catenoid to helicoid transformation of an isotropic material no longer exists with material anisotropy.Master of Science
This thesis presents two studies on the subject of thin, elastic bodies, otherwise known as plates. Plate theory has important applications in many areas of life, ranging from the design and construction of civil structures to the mechanics of wrinkling sheets. In the first work, we discuss how different elastic plate theories have qualitatively different predictions on how a plate will behave when bent. We discuss the different physical implications of each model, and relate our findings to previous studies. Additionally, we promote the use of certain technical measures in the study of plates corresponding to the most coherent definitions of bending and stretching. In the second work, we study the effects of in-plane swelling gradients on elastic plates whose material stiffnesses vary with direction. Inspired by wood panels that warp when exposed to moisture, we model elastic plates exposed to various swelling patterns and determine the resulting warped shapes. We find that some shapes are axisymmetric, while others prefer to twist when exposed to moisture-induced swelling. By varying certain parameters of the swelling functions, or by increasing the material fiber stiffness, we also find a qualitative change in shape from an axisymmetric to a twisted surface.

Le role des entreprises publiques au sein de l'economie beninoise s'est intensifie considerablement depuis le milieu des annees 1970. En effet, les orientations politiques prises a cette epoque firent de l'entreprise publique un instrument capital de la politique economique. L'objectif poursuivi etait d'assurer un controle public elargi des activites de production dans les secteurs cle de l'economie nationale. Les raisons du developpement accelere du secteur public sont multiples et se retrouvent notamment dans : -la faiblesse des structures economiques issues de l'heritage colonial, -l'instabilite politique et l'echec economique des premieres annees d'independance, -l'incapacite du secteur prive a effectuer des investissements de grande envergure, -la volonte politique des autorites publiques a intervenir directement dans la vie economique. Mais les nombreuses entreprises creees et celles nationalisees, se heurtaient a des obstacles redoutables parmi lesquels : -les erreurs de conception et de programmation des projets d'investissement, -la lourdeur administrative et le manque d'autonomie de gestion, -la penurie de dirigeants experimentes, -l'insuffisance des ressources financieres. Tous ces problemes paralysent la bonne gestion des entreprises dont les performances sont nettement insuffisantes. Les resultats financiers sont faibles et l'endettement est preoccupant. Pour parer a cette tendance flechissante des performances des entreprises, les pouvoirs publics s'efforcent maintenant de mettre en oeuvre des reformes d'assainissementThe public enterprises' role in beninese economy was considerably intensified in the middle of 1970's. Indeed, the political orientations at that time maked public enterprises as a main economical weapon. The aim was to affirm a wide state control on the out put of the main national sectors. The reasons why the public sectors' deployment was accelarated are multiple, among which : -economical structures failing due to the colonial heritage, -political instability and the first independance years economic failure, -private sector's inability to a large scale investment, -state authority's will to intervene directly into the economy, but the verious new and nationalised firms were clashing to terrible obstacles among which : -investment's shemes and conception errors, -oppressive administration and the lack of management autonomy, -deficiency of experienced managers, -insufficiency of financial resources. All these problems paralysed the favourable firms management of which the performances are clearly inadequate. Financial results are deficient and the running into debts is disquieling. To resolve the performance's inclination of public enterprises, the gouvernment is strying now to adapt purifying reforms

Benign prostatahyperplasi (BPH) är en av de vanligaste sjukdomarna hos män och kan vara en orsak till lidande. Hur omfattande lidandet är hos dem som drabbas är individuellt. Studiens syfte var att belysa patienters lidande vid BPH. En systematisk litteraturstudie valdes som metod. Sökning i relevanta databaser; Cinahl, PubMed, PsycINFO och ELIN@Kalmar, utfördes och därefter följde kritisk granskning, dataanalys och sammanställning av vetenskapligt material inom problemområdet. I dataanalysen framkom tre teman: fysiskt, emotionellt samt sexuellt lidande. Det fanns rädsla för prostatacancer och för att vara beroende av andra. En annan typ av rädsla gällde urinläckage som syntes utåt. Förändrade miktionsvanor upplevde patienter som pinsamma. Vanliga symtom vid BPH var svag urinstråle, urinläckage samt frekventa toalettbesök. Genom en gruppkonstellation av patienter, urologer och anhöriga där erfarenheter kunde utbytas, underlättades det fortsatta livet med sjukdomen. Trots allt fanns en acceptans och uppfattning om att sjukdomen är en naturlig del av åldrandet. För att kunna agera stödjande till patienter med BPH bör sjuksköterskan initiera till samtal med patienten utan att negligera de sexuella funderingar patienten eventuellt kan ha. Att anordna gruppmöten så att patienter kan utbyta erfarenheter med varandra kan vara värdefullt.

This thesis presents a model of fabric bending hysteresis. The hysteresis model is designed to reproduce the fabric bending measurements taken by the Kawabata Evaluation System (KES) and the model parameters can be derived directly from these property measurements. The advantage to using this technique is that it provides the ability to simulate a continuum of property curves. Results of the model and its components are compared and constrasted with experimental results for fabrics composed of different weaves and yarn types. An attempt to incorporate the bending model as part of a fabric drape simulation is also made.

A study has been made of glass fibre reinforced plastic beams in three-point bending. In recent years, the importance of flexural loading in composites has manifested itself in the form of composite leaf springs, helicopter rotors, and other applications. This study is directed at the initiation, growth, characterization and measurement of damage in unidirectional and cross-ply composite beams.
Beams were tested in three-point static and cyclic bending. Following damage initiation, either by a machined notch or by repeated cycling, damage growth has been characterized by two damage parameters: a damage depth encompassing a number of broken fibres on the tensile surface at the central load point, and a damage length or delamination parallel to the beam longitudinal axis.
A model was developed to predict the compliance, or deflection under applied load, as a function of beam properties and damage dimensions. The model is able to predict the compliance of damaged beams with reasonable accuracy. From fracture mechanics concepts it is shown that the two damage dimensions, depth and length, are related. It is concluded that the increase in compliance, a result of the growing damage dimensions, is related to the growth of the damage depth; the damage length follows from the relation between damage parameters and the compliance follows from the compliance model.
The damage state can thus be determined by compliance measurements if the relevant material properties and loading conditions are known. However, in service, compliance measurements may not be practical. Therefore a section of this study is devoted to an alternative damage measurement technique, namely acoustic emission monitoring. Damage initiation, compliance, damage length and damage depth were measured with AE monitoring techniques.Applied Science, Faculty of

The springback phenomenon was studied by a series of draw-bend tests. These tests were done by varying the blankholding pressure with different lubrication conditions, and with different transverse anisotropy directions. The purpose is to find the forming loads, the thickness changes and the springback angles. It has been found that the springback angle after unloading depends on the amount of blankholding pressure, the material properties, and the tool geometry. Increasing the blankholding pressure almost eliminates the springback if the tensile stress caused by the blankholding pressure reaches the yield in the material. To compliment the experiments, a theoretical model has been developed by calculating the tensile strain developed from applying the blankholding pressure. This strain then was considered in finding the total bending moment.

Benign familial haematuria (BFH) is an inherited renal disorder characterised by the presence of haematuria and the absence of progressive renal dysfiinction. Analysis of renal biopsies from affected individuals has shown that typically the only abnormality is widespread thinning of the glomerular basement membrane (GEM) visible on electron microscopy (EM). Thinning of the GBM has also been observed as the sole abnormality in patients with nonfamilial (isolated) haematuria, resulting in the diagnostic term thin basement membrane disease (TBMD). It is possible that some patients with benign familial haematuria have normal basement membranes, while others have thin basement membranes. The predominance of TBMD in patients with BFH has led some authors to use the terms interchangeably, but there are also some patients with thin basement membrane who do not have a benign prognosis. Thus the precise relationship between an abnormally thin GBM, isolated haematuria and BFH remains unclear.
