Passive Ranging Using Infra-Red Atmospheric Attenuation

Methods of estimating range to an emissive target based on the depth of an atmospheric absorption band are demonstrated. The present work uses measurements of the CO2 absorption band centered at 2.0 µm where signal-to-background ratios are maximum for many applications. Model results, based on high-resolution transmission molecular absorption (HITRAN) database cross sections, are used to predict range accuracy at ranges of up to 50 km and are compared with short range (\u3c5km) experimental results. The spectra of 23 high explosive events were used to validate the model. Using the assumption of a blackbody spectrum, extracted ranges consistently underestimated the true range by approximately 13%. By incorporating the stoichiometry of the fireball from previous research and using particulate contribution as a parameter, the error for the range estimates could be reduced to 3%

Gebser\u27s Integral Consciousness and Living in the Real World: Facilitating its Emergence Using A Course In Miracles

This paper discusses certain parallels between the work of Jean Gebser, the European philosopher and student of consciousness, and A Course in Miracles (ACIM), a contemporary spiritual system. More specifically, it 1) establishes parallels between Gebser’s conception of the ego, especially its basis in anger, and the ego according to ACIM, and 2) shows how a forgiveness exercise may lead to a time-free present, called in ACIM, “The Holy Instant.

Quantification of mutant huntingtin protein in cerebrospinal fluid from Huntington's disease patients.

Quantification of disease-associated proteins in the cerebrospinal fluid (CSF) has been critical for the study and treatment of several neurodegenerative disorders; however, mutant huntingtin protein (mHTT), the cause of Huntington's disease (HD), is at very low levels in CSF and, to our knowledge, has never been measured previously

Knowledge Translation of Interprofessional Collaborative Patient-Centred Practice: The Working Together Project Experience

The Working Together (WT) project involved the design and delivery of an online learning resource for healthcare teams in long-term care (LTC) so that knowledge regarding interprofessional collaborative patient-centred practice (ICPCP) could be readily accessed and then transferred to the workplace. The purpose of this paper is to better understand the process of knowledge translation in continuing education for healthcare professionals by documenting our experiences using Lavis et al.’s (2003) organizing framework for knowledge transfer, and highlighting the impact this approach had on the design, development, delivery, and evaluation of the WT program. Fifty-nine pharmacists, physicians, nurses, and nurse practitioners from 17 LTC homes across Ontario, Canada participated in this project. The effectiveness of the knowledge translation of ICPCP through the WT project was evaluated using the Demand-Driven Learning Model (DDLM) evaluation tool (MacDonald, Breithaupt, Stodel, Farres, & Gabriel, 2002) to assess learners’ reactions to the learning resource. Data from quantitative pre-post surveys and qualitative interviews revealed that learners found using the WT online resource to be a satisfactory learning experience, obtained new knowledge and skills regarding ICPCP, transferred knowledge to the workplace, and reported that learning had a positive effect on the residents they cared for.Le projet Working Together (WT) comprend la conception et la production d’une ressource d’apprentissage en ligne pour les équipes de professionnels prodiguant des soins de santé de longue durée (SLD) afin que les connaissances relatives à la pratique interprofessionnelle en collaboration axée sur le patient (PICAP) puissent être facilement accessibles, puis transférées dans le milieu de travail. L’objectif de cet article est de mieux comprendre le processus d’application des connaissances dans la formation continue des professionnels de la santé en documentant notre expérience à l’aide de Lavis et coll. (2003), en établissant un cadre théorique pour le transfert des connaissances et en mettant en évidence l’incidence de cette approche sur la conception, le développement, la réalisation et l’évaluation du programme WT. Cinquante-neuf pharmaciens, médecins, infirmiers et infirmières, infirmiers et infirmières praticiens de 17 centres de SLD en Ontario, au Canada, ont participé à ce projet. L’efficacité de l’application des connaissances de la PICAP à l’échelle du projet WT a été évaluée à l’aide du modèle d’apprentissage axé sur la demande (DDLM) (MacDonald, Breithaupt, Stodel, Farres et Gabriel, 2002) afin de déterminer les réactions des apprenants à la ressource d’apprentissage. Des données tirées de prétest et de postest quantitatifs ainsi que d’entrevues qualitatives ont révélé que les apprenants étaient satisfaisants de l’expérience d’apprentissage que procure la ressource en ligne WT, qu’ils ont acquis de nouvelles connaissances et aptitudes concernant la PICAP et mis en application ces connaissances dans leur milieu de travail, et que l’apprentissage a eu un effet positif sur les pensionnaires dont ils prennent soin

Relationship of Fungal Vaginitis Therapy to Prior Antibiotic Exposure

Objective: To address the putative association of antibiotic use and subsequent yeast vaginitis in a population of non-pregnant women. Methods: Three hundred and sixteen women who received medical care in rural family medicine clinics enrolled in this study. Participants were pre-menopausal and non-pregnant and were followed until they used a course of antifungal therapy for vaginitis, became pregnant or moved from the catchment area. At entry subjects were free of vaginitis symptoms and had taken no antibiotics for 30 days. Patients were followed by repeated review of clinic records, hospital records and telephone or personal interviews. Data collection included documentation of episodes of antifungal treatment for vulvovaginal candidiasis and confirmed antibiotic treatment or credible history of antibiotic use prior to the use of antifungal therapy. Physician-reported uses of antibiotic and antifungal as well as patient-reported uses of these were recorded. Results: There were four reported cases of antifungal therapy following within a month of antibiotic use, in contrast to 484 antibiotic uses not followed by antifungal use. If time of observation was extended to 6 months from antibiotic use, there were 13 uses of antifungal therapy after antibiotics and 475 uses of antibiotics not followed by antifungal therapy. Conclusion: Our results cast doubt on the association of antibiotics as a putative cause of yeast vulvovaginitis

Direct measurements of ice-shelf flexure caused by surface meltwater ponding and drainage.

Global sea-level rise is caused, in part, by more rapid ice discharge from Antarctica, following the removal of the restraining forces of floating ice-shelves after their break-up. A trigger of ice-shelf break-up is thought to be stress variations associated with surface meltwater ponding and drainage, causing flexure and fracture. But until now, there have been no direct measurements of these processes. Here, we present field data from the McMurdo Ice Shelf, Antarctica, showing that the filling, to ~2 m depth, and subsequent draining, by overflow and channel incision, of four surface lakes causes pronounced and immediate ice-shelf flexure over multiple-week timescales. The magnitude of the vertical ice-shelf deflection reaches maxima of ~1 m at the lake centres, declining to zero at distances of <500 m. Our results should be used to guide development of continent-wide ice-sheet models, which currently do not simulate ice-shelf break-up due to meltwater loading and unloading.This work was supported by the U.S. National Science Foundation under award PLR-1443126 to the University of Chicago, a Leverhulme Early Career Fellowship (ECF-2014-412) and a CIRES Postdoctoral Visiting Fellowship, both awarded to A.F.B., and a NASA Earth and Space Science Fellowship (NNX15AN44H) awarded to G.J.M

Comments on Half S-Branes

Following hep-th/0305177, we write the boundary state of half S-brane in bosonic string theory as a grand canonical partition function of a unitary matrix model. From this representation, it follows that the annulus amplitude can be written as a grand canonical partition function of a unitary two-matrix model. We also show that the contribution of the exponentially growing couplings to the timelike oscillators can be resummed in a certain annulus amplitude.Comment: 27 pages, lanlmac; v2: reference adde
