Flux enhancement in TFC RO membranes

ENVIRONMENTAL PROGRESS & SUSTAINABLE ENERGY, Issue 1 2001
Mark A. Kuehne
The effects of varying processing conditions during fabrication of TFC RO membranes were systematically investigated. It was found that the membrane flux is greatly dependent on the processing steps that follow the synthesis of the thin film coating, such as washing, treatment with glycerol, and drying of the membrane. Glycerol is not simply a passive flux - p reserving agent, preventing loss of porosity during oven drying. In combination with a second oven drying step, glycerol actively enhances flux. Membrane flux can be similarly enhanced by treatment with solutions of organic salts, followed by oven drying. The effect of these treatments is quite large, increasing the flux by 30,70%, with no loss of salt rejection. Flux-enhancing additives were also used in the aqueous polyamine solution used to prepare the thin film coating. [source]

Perceptions of older people on disaster response and preparedness

Duggan S., Deeny P., Spelman R. & Vitale C.T. (2010) Perceptions of older people on disaster response and preparedness. International Journal of Older People Nursing5, 71,76 doi: 10.1111/j.1748-3743.2009.00203.x Most disasters occur in developing countries but in the last decade due to the increasing threat of floods, air disasters and terrorist threat, disaster response and preparedness is a growing global concern. Due to an ageing population across the world, older people now constitute a significant proportion of those at risk from disasters. This paper reports on a qualitative study carried out in Sri Lanka and in the United States where a group of older people were asked about aspects of disaster response and preparedness. The group from Sri Lanka (n = 9) who had direct experience of the 2004 Indian Ocean Tsunami were asked how they perceived international aid relief and a group of white Caucasians from East Coast USA (n = 8) were asked about disaster preparedness. Findings indicate that both groups had similar issues albeit that they were looking at different phases of the disaster cycle and from different cultural perspectives. Both groups identified issues related to, protecting the rights of the older person and preventing loss of independence in responding and preparing for a disaster, mistrust of government and access to resources and all expressed strong feelings of self-responsibility.

A Three-Dimensional Simulation of Age-Related Remodeling in Trabecular Bone,

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 4 2001
J. C. Van Der Linden
Abstract After peak bone mass has been reached, the bone remodeling process results in a decrease in bone mass and strength. The formation deficit, the deficit of bone formation compared with previous resorption, results in bone loss. Moreover, trabeculae disconnected by resorption cavities probably are not repaired. The contributions of these mechanisms to the total bone loss are unclear. To investigate these contributions and the concomitant changes in trabecular architecture and mechanical properties, we made a computer simulation model of bone remodeling using microcomputed tomography (micro-CT) scans of human vertebral trabecular bone specimens. Up to 50 years of physiological remodeling were simulated. Resorption cavities were created and refilled 3 months later. These cavities were not refilled completely, to simulate the formation deficit. Disconnected trabeculae were not repaired; loose fragments generated during the simulation were removed. Resorption depth, formation deficit, and remodeling space were based on biological data. The rate of bone loss varied between 0.3% and 1.1% per year. Stiffness anisotropy increased, and morphological anisotropy (mean intercept length [MIL]) was almost unaffected. Connectivity density increased or decreased, depending on the remodeling parameters. The formation deficit accounted for 69,95%, disconnected trabeculae for 1,21%, and loose fragments for 1,17% of the bone loss. Increasing formation deficit from 1.8% to 5.4% tripled bone loss but only doubled the decrease in stiffness. Increasing resorption depth from 28 to 56 ,m slightly increased bone loss but drastically decreased stiffness. Decreasing the formation deficit helps to prevent bone loss, but reducing resorption depth is more effective in preventing loss of mechanical stiffness. [source]

A major QTL for resistance of rice to the parasitic plant Striga hermonthica is not dependent on genetic background

PEST MANAGEMENT SCIENCE (FORMERLY: PESTICIDE SCIENCE), Issue 5 2009
Philip J Swarbrick
Abstract BACKGROUND: The use of Striga -resistant germplasm is likely to be a cost-effective control strategy for preventing loss of yield owing to Striga. Previously, the authors identified quantitative trait loci (QTL) for resistance in rice to Striga hermonthica (Del.) Benth. in backcross inbred lines (BILs) derived from a cross between two cultivars Nipponbare and Kasalath. It is essential to validate QTL in different environments and/or genetic backgrounds to develop molecular markers linked to resistance QTL for use in marker-assisted selection (MAS) programmes. This study aimed to establish whether a large-effect Kasalath-derived resistance QTL allele on chromosome 4 of rice also conferred resistance in a different mapping population derived from a cross between Koshihikari and Kasalath, and to identify any further Striga resistance QTL. RESULTS: Three Striga resistance QTL were detected in Koshihikari,Kasalath BILs, two of which were derived from the Kasalath allele and one from the Koshihkari allele. The largest QTL (Kasalath allele) explained 16% of the variation in the mapping population and was located on chromosome 4. Comparison between these data and those of the authors' previous analysis revealed that the confidence intervals of the chromosome-4 QTL in the Nipponbare,Kasalath cross and the Kasalath,Koshihikari cross overlapped between 6.5 Mbp and 8 Mbp on the physical rice genome assembly. CONCLUSION: This study has both verified and narrowed down the position of a Striga resistance QTL of major effect, and demonstrated that it may be a tractable target for MAS.
