    The adaptive optics system for the Thirty Meter Telescope (TMT) is the Narrow-Field InfraRed Adaptive Optics System (NFIRAOS). Recently, INO has been involved in the optomechanical design of several subsystems of NFIRAOS, including the Instrument Selection Mirror (ISM), the NFIRAOS Beamsplitters (NBS), and the NFIRAOS Source Simulator system (NSS) comprising the Focal Plane Mask (FPM), the Laser Guide Star (LGS) sources, and the Natural Guide Star (NGS) sources. This paper presents an overview of these subsystems and the optomechanical design approaches used to meet the optical performance requirements under environmental constraints

    Bei dem Life Story Board (LSB) handelt es sich um ein visuelles Tool, das in therapeutischen Kontexten zum Einsatz kommt, um die Lebenswelt zu ko-konsturieren, die die persönlichen, relationalen und zeitlichen Aspekte individueller gelebter Erfahrung umfasst. In unserer Studie zu Drogennutzung und Schadensreduzierung interviewten wir Menschen, die Drogen injizieren unter Einsatz des LSB, um herauszufinden, ob sich hieraus Potenziale für eine verbesserte qualitative Forschung ergeben könnten. In unserem Forschungsteam arbeiteten neben Akademiker*innen auch frühere oder aktuelle Drogenkonsument*innen mit. Interviews wurden von jeweils zwei Personen geführt: eine agierte als Interviewer*in, die andere war für das LSB zuständig.Entlang der Ergebnisse war nachvollziehbar, dass Interviewende und Interviewte in unterschiedlicher Weise mit dem LSB interagierten: Während die Interviewer*innen es nutzten, um sich im Leitfaden zu orientieren, half es den Befragten, die eigene Lebensgeschichte mittels einer Vielzahl an emotionalen und kognitiven Äußerungen zu validieren oder zu unterstreichen. Das LSB erlaubte, sich an spezifische Situationen oder Vorfälle zu erinnern, Perspektiven hinzuzugewinnen und der eigenen Geschichte zusätzlichen Sinn zu verleihen. Insoweit arbeiteten Interviewte und Interviewende unter jeweils unterschiedlichen Vorzeichen mittels des LSB gemeinsam an einer (Re-)Präsentation der jeweiligen Lebensgeschichte.The Life Story Board (LSB) is a visual tool used in therapeutic circumstances to co-construct a lifescape that represents the personal, relational and temporal aspects of a person's lived experiences. We conducted a study of the drug use and harm reduction experiences of people who inject drugs through research interviews using the LSB to determine whether it has the potential to enhance qualitative research. Our team included community researchers who were current or former drug users and academic researchers. Interviews were conducted by two community researchers: an interviewer and a storyboarder who populated the LSB.Results showed that interviewers and participants interacted with the LSB in different ways. The board functioned to situate the interviewers in the interview schedule, whereas participants often used the board as a way to validate or reinforce their life story. Participants expressed a variety of emotional and cognitive responses to the board. Overall, the LSB helped participants focus on their life story to recall specific occasions or incidents and enabled them to gain perspective and make greater sense of their lives. Both participants and interviewers engaged with the LSB in nuanced ways that enabled them to work together to represent the participant's life story

    Prostatic artery embolization for intractable hematuria in patients with unregulated coagulation parameters: three case reports

    Get PDF
    Introduction: Benign prostatic hyperplasia is a prevalent disease that could be responsible of severe intractable hematuria requiring invasive surgical management. Case presentation: We report three high-risk cases presented with intractable hematuria of prostatic origin with high medical co-morbidities treated safely and effectively by prostatic artery embolization with favorable outcomes. Conclusions: In non-surgical, anticoagulated patients, prostatic artery embolization represents a safe and effective intervention for the treatment of intractable hematuria related to benign prostatic hyperplasia

    Enjeux et solutions pour la sylviculture intensive de plantations dans un contexte d'aménagement écosystémique

    Les plantations forestières représentent un outil sylvicole reconnu pour assurer un approvisionnement en matière ligneuse qui répond aux attentes de la société envers l'aménagement durable des forêts. Toutefois, elles font aussi partie du scénario sylvicole qui a le plus grand potentiel d'artificialisation de la forêt naturelle. Les objectifs de la sylviculture intensive de plantations peuvent alors paraître, de prime abord, en contradiction avec ceux de l'aménagement écosystémique. Nous décrivons le processus par lequel nous avons défini et documenté des enjeux associés aux plantations et proposé des pistes de solutions pour que la sylviculture intensive de plantations puisse s'intégrer à l'aménagement écosystémique. Nous avons identifié des enjeux relatifs à l'ampleur, à la localisation et à l'agencement spatial des plantations, aux attributs clés et à la résilience de la forêt naturelle, à l'acceptabilité sociale, ainsi qu’à la productivité et à la rentabilité des plantations. Nous avons également proposé des pistes de solutions qui permettraient de réaliser les plantations dans un contexte d'aménagement écosystémique, telles que la modulation des traitements sylvicoles pour augmenter la naturalité des plantations, la réalisation des traitements de manière à obtenir la production attendue, ainsi qu'un déploiement dans le paysage qui intègre les préoccupations des parties prenantes et qui considère la naturalité de la matrice forestière. Forest plantations are recognized as a silvicultural tool for ensuring a timber supply that meets public expectations regarding sustainable forest management. However, they are also part of the silvicultural scenario that shows the greatest potential for the artificialization of natural forests. From a firsthand perspective, intensive plantation silviculture objectives may appear antagonistic to those of ecosystem management. Here we describe the process through which we defined and documented plantation issues, then propose potential solutions to allow the integration of intensive plantation silviculture into ecosystem management. We identify issues related to the scale, localization and spatial arrangement of plantations, the key attributes and resilience of natural forests, social acceptability, and the productivity and profitability of plantations. We also propose potential solutions likely to help manage plantations within a context of ecosystem management. These include modulating silvicultural treatments to enhance the naturalness of plantations, conducting treatments to obtain expected production rates, and ensuring that plantations are deployed across the landscape in a manner that integrates stakeholder concerns and considers the naturalness of the forest matrix

    CNS targets of adipokines

    Get PDF
    This is the author accepted manuscript. The final version is available from American Physiological Society via the DOI in this record.Our understanding of adipose tissue as an endocrine organ has been transformed over the last twenty years. During this time a number of adipocyte-derived factors or adipokines have been identified. This paper will review evidence for how adipokines acting via the central nervous system (CNS) regulate normal physiology and disease pathology. The reported CNS-mediated effects of adipokines are varied and include the regulation of energy homeostasis, autonomic nervous system activity, the reproductive axis, neurodevelopment, cardiovascular function, and cognition. Due to the wealth of information available and the diversity of their known functions, the archetypal adipokines leptin and adiponectin will be the focused on extensively. Other adipokines with established CNS actions will also be discussed. Due to the difficulties associated with studying CNS function on a molecular level in humans, the majority of our knowledge, and as such the studies described in this paper, comes from work in experimental animal models; however, where possible the relevant data from human studies are also highlighted
