Wet atmospheric generation apparatus

The invention described relates to an apparatus for providing a selectively humidified gas to a camera canister containing cameras and film used in space. A source of pressurized gas (leak test gas or motive gas) is selected by a valve, regulated to a desired pressure by a regulator, and routed through an ejector (venturi device). A regulated source of water vapor in the form of steam from a heated reservoir is coupled to a low pressure region of the ejector which mixes with high velocity gas flow through the ejector. This mixture is sampled by a dew point sensor to obtain dew point thereof (ratio of water vapor to gas) and the apparatus adjusted by varying gas pressure or water vapor to provide a mixture at a connector having selected humidity content

North by Northwest : Information literacy at Yukon College and Lakehead University

In Northern communities, isolation is a fact of life and common southern "realities" like high-speed internet, libraries (both public and academic) within driving distance and f2f instruction are not the norm. Due to these factors, online instruction is a core component in northern academic institutions and as such requires a little bit more preparation. As well, another key factor to consider is the diverse student population: First Nations, mature, part-time, first generation university students, and professionals upgrading their credentials. The diverse academic backgrounds of these students makes designing the standard library tutorial a challenge; one size does not fit all in the north. At the same time, this might be the only way that students interact with a librarian so the online environment becomes significant to these students' academic studies (and hopefully success). So how does an academic library with such a variety of students a) reach these students? b) design online tutorials targeting a variety of learning styles? and c) assess whether any of this is working? This session will show you how to take a generic one hour information literacy class and turn it into an online session that will meet the needs of a diverse student population. The presenters will discuss effective pedagogical approaches to online instruction, how to teach specific e-resources and finally how to ensure that the students are actually finding the Library's e-resources and using them effectively and efficiently. This presentation won't focus as much on software, although we will be discussing what we use, it's more about how to use the software to teach InfoLit online effectively. We will conclude with a discussion on how to beta-test your new online approach to Information Literacy Instruction before launching it live for the students. So, come to this session and see how two northern (Ontario and Yukon) librarians are devising new and alternative methods of reaching out to students via a variety of methods and assessing their efforts. How, in fact, we have to examine "every angle" such as mode of delivery, type of student, pedagogical theory, etc. to ensure that we are serving our diverse populations well and contributing to the retention and success of these students

Quantifying and visualising change: strain monitoring of tapestries with digital image correlation

A three-year research project at the University of Southampton (2007–2010) investigated whether monitoring techniques commonly used by engineers to assess the strength and durability of materials could be usefully applied to inform the condition assessment of historic tapestries. To date it has not been possible to obtain an objective picture of the overall condition of a tapestry; the study investigated whether it is possible to identify precursors of structural damage. The two techniques, digital image correlation (DIC) and optical fibre sensors, were used to monitor a representative wool fabric, specially woven tapestry samples, a newly woven tapestry, and historic tapestries, both in the laboratory and in situ in a historic house. This study first sets out to answer the question: can DIC be used to monitor and visualize strain in historic tapestries? It is shown that DIC can be used successfully. Secondly, it discusses the map function, a novel development which allowed the monitoring equipment to be moved, so that it could be used in situ in a historic house. Thirdly, it provides further details of the experimental work using optical fibre sensors to confirm the accuracy of the DIC technique

Abundance of harbor porpoise (Phocoena phocoena) in three Alaskan regions, corrected for observer errors due to perception bias and species misidentification, and corrected for animals submerged from view

Estimating the abundance of cetaceans from aerial survey data requires careful attention to survey design and analysis. Once an aerial observer perceives a marine mammal or group of marine mammals, he or she has only a few seconds to identify and enumerate the individuals sighted, as well as to determine the distance to the sighting and record this information. In line-transect survey analyses, it is assumed that the observer has correctly identified and enumerated the group or individual. We describe methods used to test this assumption and how survey data should be adjusted to account for observer errors. Harbor porpoises (Phocoena phocoena) were censused during aerial surveys in the summer of 1997 in Southeast Alaska (9844 km survey effort), in the summer of 1998 in the Gulf of Alaska (10,127 km), and in the summer of 1999 in the Bering Sea (7849 km). Sightings of harbor porpoise during a beluga whale (Phocoena phocoena) survey in 1998 (1355 km) provided data on harbor porpoise abundance in Cook Inlet for the Gulf of Alaska stock. Sightings by primary observers at side windows were compared to an independent observer at a belly window to estimate the probability of misidentification, underestimation of group size, and the probability that porpoise on the surface at the trackline were missed (perception bias, g(0)). There were 129, 96, and 201 sightings of harbor porpoises in the three stock areas, respectively. Both g(0) and effective strip width (the realized width of the survey track) depended on survey year, and g(0) also depended on the visibility reported by observers. Harbor porpoise abundance in 1997–99 was estimated at 11,146 animals for the Southeast Alaska stock, 31,046 animals for the Gulf of Alaska stock, and 48,515 animals for the Bering Sea stock

Diversity and altitudinal niche width characteristics for 35 taxa of the Papua New Guinea Frullania flora with consideration of sibling pairs

The Frullania taxa on Mount Albert Edward, Papua New Guinea, form many associations that suggest a high degree of niche similarity, but at different altitudes, different associations form. The species diversity of the genus is greatest at the middle altitudes and least in the dry lowlands. This altitudinal separation is apparent in the niche widths of the taxa. The members of the four sibling taxa pairs examined exhibit distinct altitudinal niches, suggesting that the sibling taxa are distinct, with different niche optima

International Partnerships: A Model for Educational Organizations

Opportunities exist for faculty and students within educational leadership preparation programs to participate in international initiatives within developing countries. One way to do this is through collaboration with organizations that already have an established presence in the country. Working within these organizations provides opportunities for learning and research for the educational leadership program. If done well, such work also helps host organizations meet their mission and goals. An understanding of effective behaviors in international partnerships may benefit educational leadership programs that develop these types of service opportunities. The behaviors mirror the scholar-practitioner philosophy, of which some prominent educational leadership programs adhere, through addressing pragmatic needs within a local context

Constrained trajectory optimization for kinematically redundant arms

Two velocity optimization schemes for resolving redundant joint configurations are compared. The Extended Moore-Penrose Technique minimizes the joint velocities and avoids obstacles indirectly by adjoining a cost gradient to the solution. A new method can incorporate inequality constraints directly to avoid obstacles and singularities in the workspace. A four-link arm example is used to illustrate singularity avoidance while tracking desired end-effector paths

Velocity profiles in laminar diffusion flames

Velocity profiles in vertical laminar diffusion flames were measured by using laser Doppler velocimetry (LDV). Four fuels were used: n-heptane, iso-octane, cyclohexane, and ethyl alcohol. The velocity profiles were similar for all the fuels, although there were some differences in the peak velocities. The data compared favorably with the theoretical velocity predictions. The differences could be attributed to errors in experimental positioning and in the prediction of temperature profiles. Error in the predicted temperature profiles are probably due to the difficulty in predicting the radiative heat losses from the flame
