This paper describes a prototype desiccant evaporative cooling system (DEC) and presents its performance in term of indoor humidity control and energy efficiency. Experimental and simulation results show that the desiccant evaporative cooling system can achieve better humidity control and acceptable comfort conditions. The simulation results show that the desiccant cooling system is especially well suited for areas of the country with a high latent load. However the study identified a series of improvement measures to undertake in order to improve the energy efficiency of the unit., 12th Canadian Conference on Building Science and Technology: 06 May 2009, Montréal, Québec

One technology that can help reduce the electricity consumption of conventional air-conditioning technology is the coupling of active dehumidification with evaporative cooling. In this case sensible cooling and moisture removal from indoor and outside ventilation air are decoupled. In this study simulation models are developed for a conventional vapor compression based cooling system and a desiccant evaporative cooling system installed in an R-2000 house. Electricity consumption and comfort indices are then predicted for the two systems for three regions of the country with varying sensible heat ratios. It is found that, compared to a conventional system, the desiccant evaporative cooling system can lead to significant electricity consumption reductions and also reduce the number of hours when conditions inside the space are uncomfortable., 3rd Canadian Solar Buildings Conference, August 20, 2008, Fredericton, N.B., Canada

Item does not contain fulltext Jumping translocations (JTs) and segmental jumping translocations (SJTs) are unbalanced translocations involving a donor chromosome arm or chromosome segment that has fused to multiple recipient chromosomes. In leukemia, where JTs have been predominantly observed, the donor segment (usually 1q) preferentially fuses to the telomere regions of recipient chromosomes. In this study, spectral karyotyping (SKY) and FISH analysis revealed 188 JTs and SJTs in 10 cell lines derived from carcinomas of the bladder, prostate, breast, cervix, and pancreas. Multiple JTs and SJTs were detected in each cell line and contributed to recurrent unbalanced whole-arm translocations involving chromosome arms 5p, 14q, 15q, 20q, and 21q. Sixty percent (113/188) of JT breakpoints occurred within centromere or pericentromeric regions of the recipient chromosomes, whereas only 12% of the breakpoints were located in the telomere regions. JT breakpoints of both donor and recipient chromosomes coincided with numerous fragile sites as well as viral integration sites for human DNA viruses. The JTs within each tumor cell line promoted clonal progression, leading to the acquisition of extra copies of the donated chromosome segments that often contained oncogenes (MYC, ABL, HER2/NEU, etc.), consequently resulting in tumor-specific genomic imbalances.

A laboratory test procedure and a guarded hot box facility used to determine the thermal transmission coefficient of skylights are described. Skylights can be tested at an angle of inclination that can be varied from 20 degrees to 90 degrees off the horizontal. The experimental procedure, to determine the skylight R-value, is based on a correlation for the convective heat transfer on the warm side and the weather side of the test specimen. This correlation is obtained from calibration measurements using a calibrated transfer standard (CTS) in the inclined position. The results show that the convective heat transfer along an inclined CTS is substantially different from that along a vertical CTS. Three-dimensional simulations of the conductive heat transfer within the CTS assembly are found to be in good agreement with the experimental results. A complete uncertainty analysis for the calibration experiments and for skylight testing is presented. It is found that the experimental relative uncertainty associated with the thermal transmission coefficient of the test specimen without the frame is of the order of 6%., ASHRAE Transactions: 01 January 2000, Dallas, TX., U.S.A.

http://www.bibliotheque.refer.org/biblio/chapitres.php?numpubli=39; Dresser un état des lieux de la Francophonie au Liban, tel était l'objectif assigné à l'enquête préalable, dont cet ouvrage présente les résultats les plus saillants. En outre, cette étude minutieuses pourra - c'est en tout cas le souhait exprimé par les auteurs - servir de modèle à des recherches analogues dans les différentes régions de la Francophonie, au Maghreb notamment, en l'adaptant à chaque situation nationale, afin de contribuer à constituer un état des lieux du français dans le monde. Ce recueil a le mérite de mettre fin aux appréciations approximatives dont fait l'objet la situation du français au Liban. Ces travaux permettront de mener des actions plus pertinentes en faveur de la Francophonie et de mieux cibler la coopération linguistique avec ce pays.

Les États généraux de la Francophonie scientifique ont réuni les spécialistes des sujets définis comme autant de priorités pour l'avenir du français comme langue de communication internationale.

EXECUTIVE SUMMARY: The Coastal Change Analysis Programl (C-CAP) is developinga nationally standardized database on landcover and habitat change in the coastal regions of the United States. C-CAP is part of the Estuarine Habitat Program (EHP) of NOAA's Coastal Ocean Program (COP). C-CAP inventories coastal submersed habitats, wetland habitats, and adjacent uplands and monitors changes in these habitats on a one- to five-year cycle. This type of information and frequency of detection are required to improve scientific understanding of the linkages of coastal and submersed wetland habitats with adjacent uplands and with the distribution, abundance,and health of living marine resources. The monitoringcycle will vary according to the rate and magnitude ofchange in each geographic region. Satellite imagery(primarily Landsat Thematic Mapper), aerial photography,and field data are interpreted, classified, analyzed,and integrated with other digital data in a geographicinformation system (GIS). The resulting landcoverchange databases are disseminated in digital formfor use by anyone wishing to conduct geographic analysisin the completed regions. C-CAP spatial information on coastal change will be input to EHP conceptual and predictive models to support coastal resource policy planning and analysis. CCAP products will include 1) spatially registered digital databases and images, 2) tabular summaries by state, county, and hydrologic unit, and 3) documentation. Aggregations to larger areas (representing habitats, wildlife refuges, or management districts) will be provided on a case-by-case basis. Ongoing C-CAP research will continue to explore techniques for remote determination of biomass, productivity, and functional status of wetlands and will evaluate new technologies (e.g. remote sensor systems, global positioning systems, image processing algorithms) as they become available. Selected hardcopy land-cover change maps will be produced at local (1:24,000) to regional scales (1:500,000) for distribution. Digital land-cover change data will be provided to users for the cost of reproduction.Much of the guidance contained in this document was developed through a series of professional workshopsand interagency meetings that focused on a) coastal wetlands and uplands; b) coastal submersed habitat including aquatic beds; c) user needs; d) regionalissues; e) classification schemes; f) change detectiontechniques; and g) data quality. Invited participantsincluded technical and regional experts and representativesof key State and Federal organizations. Coastal habitat managers and researchers were given an opportunity for review and comment. This document summarizes C-CAP protocols and procedures that are to be used by scientists throughout the United States to develop consistent and reliable coastal change information for input to the C-CAP nationwide database. It also provides useful guidelines for contributors working on related projects. It is considered a working document subject to periodic review and revision.(PDF file contains 104 pages.)
