    MAO (MAORY Adaptive Optics) is the a developed numerical simulation tool for adaptive optics. It was created especially to simulate the performance of the MAORY MCAO module of the Extremely Large Telescope. It is a full end-to-end Monte-Carlo code able to perform different flavors of adaptive optics simulation. We used it to investigate the performance of a the MAORY and some specific issue related to calibration, acquisition and operation strategies. As, MAORY, MAO will implement Multi-conjugate Adaptive Optics combining Laser Guide Stars (LGS) and Natural Guide Stars (NGS) measurements. The implementation of the reference truth WFS completes the scheme. The simulation tool implements the various aspect of the MAORY in an end to end fashion. The code has been developed using IDL and use libraries in C++ and CUDA for efficiency improvements. Here we recall the code architecture, we describe the modeled instrument components and the control strategies implemented in the code

    MAORY: adaptive optics module for the E-ELT

    Get PDF
    MAORY is one of the four instruments for the E-ELT approved for construction. It is an adaptive optics module offering two compensation modes: multi-conjugate and single-conjugate adaptive optics. The project has recently entered its phase B. A system-level overview of the current status of the project is given in this paper

    FUNDAMENTOS: A hiperidrose é um distúrbio pouco conhecido, caracterizado pela produção excessiva de suor. Manifesta-se sob várias formas, afetando áreas como axilas, mãos, pés e face. Seus sintomas trazem prejuízos para o paciente, desde limitações no trabalho até constrangimento social e transtornos psicológicos. OBJETIVOS: O objetivo deste trabalho é estimar a prevalência de hiperidrose na cidade de Blumenau. MÉTODOS: A pesquisa foi realizada entre 21 de agosto e 1o de setembro de 2006, nos terminais urbanos de Blumenau: SC, entrevistando-se 500 pessoas abordadas de forma aleatória. RESULTADOS: Dentre os entrevistados, 45 deles, que correspondem a 9% do total, preencheram os requisitos mínimos para serem classificados como portadores de hiperidrose. A faixa etária mais acometida foi entre 18 e 30 anos (11,8%). O número de portadores de hiperidrose do sexo masculino foi maior em números tanto absolutos quanto relativos. A característica mais prevalente foi frequência de hiperidrose ao menos uma vez por semana, encontrada em 91,11% dos afetados; a menos prevalente foi cessação de suor durante o sono, presente em 37,77%. CONCLUSÕES: Observa-se que a prevalência de hiperidrose em Blumenau é maior que a encontrada em outras pesquisas semelhantes, não evidenciando raridade na presente amostra.<br>BACKGROUND: Hyperhidrosis is a little known disorder, characterized by excessive production of sweat. Hyperhidrosis may occur under several circumstances and appears in body parts like armpits, hands, feet, and face, consequently causing problems to the patient like job limitation, social embarrassment, and psychological damage. OBJECTIVES: Using these theoretical views as a starting point, the study aimed to evaluate the prevalence of hyperhidrosis in Blumenau. METHODOLOGY: Utilizing interviews, the research was conducted with 500 subjects randomly approached, in the period ranging from August 21 to September 1st, 2006. RESULTS: 45 respondents (9%) matched the pre-requisites, being classified as hyperhidrosis patients. The age group most affected was from 18 to 30 years (11.8%). Hyperhidrosis was more frequent among men both in absolute (24 men against 21 women) and relative numbers (10.62% of men against 7.66% of women). The most prevalent characteristic was "at least one occurrence per week", in 91.11% of patients; the least prevalent occurrence was "cessation of sweat during sleep", in 37.77% of respondents. CONCLUSIONS: The data show that the prevalence of hyperhidrosis in Blumenau is higher when compared with other studies, thus indicating that it is not a rare phenomenon

    Caracterização da qualidade de vida segundo o estado menopausal entre mulheres da Região Sul do Brasil Characterization of the quality of life by menopausal status among women in the South region of Brazil

    OBJETIVOS: caracterizar a qualidade de vida de mulheres climatéricas residentes na Região Sul segundo o estado menopausal delas. MÉTODOS: foram entrevistadas 236 mulheres com idades entre 40 e 65 anos, durante feira de saúde realizada em cidade do Sul do Brasil, em março de 2005. Na avaliação da qualidade de vida, utilizou-se a versão brasileira do instrumento Menopause Rating Scale. RESULTADOS: das entrevistadas, 133 eram pré-menopáusicas e 103 pós-menopáusicas. As primeiras referiram sintomas climatéricos moderados e severos em 37,6% e 24,0%, respectivamente, enquanto as mulheres pós-menopáusicas, relataram sintomas moderados e severos em 36,9% e 39,4% dos casos, respectivamente. Os escores globais de qualidade de vida não mostraram diferenças entre os grupos estudados (p=0,12), ainda que o grupo pré-menopáusico tenha referido mais sintomas psicológicos (p=0,05) e o pós-menopáusico mais sintomas somato-vegetativos (p<0,01) e urogenitais (p=0,01). CONCLUSÕES: a qualidade de vida não foi influenciada pelo estado menopausal neste estudo. A maior severidade dos sintomas somato-vegetativos no grupo pós-menopáusico provavelmente se deva ao maior hipoestrogenismo nessa fase, favorecendo sintomas vasomotores e atrofia urogenital. A maior severidade dos sintomas psicológicos entre as mulheres pré-menopáusicas pode estar relacionada à maior preocupação acerca da menopausa e suas implicações para saúde.<br>OBJECTIVES: to characterize the quality of life of climacteric women residing in the South region by menopausal status. METHODS: two hundred and thirty-six women aged between 40 and 65 were interviewed during a health fair held in March 2005 in a city in the South of Brazil. Their quality of life was assessed using the Brazilian version of the Menopause Rating Scale. RESULTS: of those interviewed, 133 were pre-menopausal and 103 post-menopausal. Moderate and severe climacteric symptoms were reported by 37.6% and 24.0% of the former, respectively, while 36.9% and 39.4% of the post-menopausal women reported moderate and severe symptoms, respectively. There were no differences between the two groups studied in terms of overall scores on the quality of life scale (p=0.12), although the pre-menopausal group reported more psychological symptoms (p=0.05) and the post-menopausal group more somatic-vegetative (p<0.01) and urinogenital (p=0.01) symptoms. CONCLUSIONS: quality of life was not influenced by menopausal status among the women covered by this study. The greater severity of somatic-vegetative symptoms in the post-menopausal group is probably due to the greater likelihood of hypoestrogenism at this stage in life, which may lead to vasomotor symptoms and urinogenital atrophy. The greater severity of psychological symptoms among pre-menopausal women may be related to a higher level of concern regarding menopause and its possible health implications
