摘要： One issue for community groups, local and regional planners, and politicians, is that they require relevant information to develop programs and initiatives for incorporating sustainability principles into their physical infrastructure, operations, and decision-making processes. This research project addressed the issue through two research questions. The that this project was designed to address, which was greatly influenced by the vast number of references in the sustainability literature, was an ontological one, " ". The that this project answered was, " ". The Multi-Sector Sustainability Browser ( is a decision support tool () designed to synthesize and summarize research in four sustainability decision domains, Land Use, Buildings and Infrastructure, Transportation, and Materials Management in a manner that provides easy and rapid access to information for use in planning and decision making. Weblinks are provided to reference documents and resources from the four sustainability decision domains, allowing users to download relevant documents and extract information in support of sustainability decisions and related program initiatives.

关键词： Eclipta prostrata   Ulcerative Colitis   Intestinal Epithelial Cell   Nuclear Factor-kappa B  

摘要： Eclipta prostrata (EP) and its compounds are known to have several pharmacological effects including anti-inflammatory effects. In the present study, we demonstrated that EP improves the dextran sulfate sodium (DSS)-induced colitis symptoms such as body weight loss, colon length shortening and disease activity index. In DSS-induced colitis tissue, EP controls the protein expressions of cyclooxygenase-2 (COX-2) and hypoxia inducible factor-1 alpha (HIF-1 alpha). In addition, the release of prostaglandin E-2 and vascular endothelial growth factor-A were significantly reduced by EP administration. EP also inhibited COX-2 and HIF-1 alpha expressions in the tumor necrosis factor-alpha stimulated HT-29 cells. These inhibitory effects of EP occurred by reducing the phosphorylation of I kappa B and the translocation of the nuclear factor-kappa B (NF-kappa B). Additionally, we found through HPLC analysis that wedelolactone, which is an inhibitor of NF-kappa B transcription, was contained in water extract of EP. These results indicate that EP can improve colitis symptoms through the modulation of immune function in intestinal epithelial cells and suggests that EP has the potential therapeutic effect to intestinal inflammation.

关键词： E-maintenance   Centrifugal compressor   Condition monitoring data   Imputation techniques   Missing data  

摘要： Purpose - Centrifugal compressors are integral components in oil industry, thus effective maintenance is required. Condition-based maintenance and prognostics and health management (CBM/PHM) have been gaining popularity. CBM/PHM can also be performed remotely leading to e-maintenance. Its success depends on the quality of the data used for analysis and decision making. A major issue associated with it is the missing data. Their presence may compromise the information within a set, causing bias or misleading results. Addressing this matter is crucial. The purpose of this paper is to review and compare the most widely used imputation techniques in a case study using condition monitoring measurements from an operational industrial centrifugal compressor. Design/methodology/approach - Brief overview and comparison of most widely used imputation techniques using a complete set with artificial missing values. They were tested regarding the effects of the amount, the location within the set and the variable containing the missing values. Findings - Univariate and multivariate imputation techniques were compared, with the latter offering the smallest error levels. They seemed unaffected by the amount or location of the missing data although they were affected by the variable containing them. Research limitations/implications - During the analysis, it was assumed that at any time only one variable contained missing data. Further research is still required to address this point. Originality/value - This study can serve as a guide for selecting the appropriate imputation method for missing values in centrifugal compressor condition monitoring data.

关键词： parasites   rSj16   inflammatory bowel disease   protective effects   PPAR-alpha  

摘要： Background: Epidemiologic studies and animal model experiments have shown that parasites have significant modulatory effects on autoimmune disorders, including inflammatory bowel disease (IBD). Recombinant Sj16 (rSj16), a 16-kDa secreted protein of Schistosoma japonicum (***) produced by Escherichia coli (E. coli), has been shown to have immunoregulatory effects in vivo and in vitro. In this study, we aimed to determine the effects of rSj16 on dextran sulfate sodium (DSS)-induced colitis. Methods: DSS-induced colitis mice were treated with rSj16. Body weight loss, disease activity index (DAI), myeloperoxidase (MPO) activity levels, colon lengths, macroscopic scores, histopathology findings, inflammatory cytokine levels and regulatory T cell (Treg) subset levels were examined. Moreover, the differential genes expression after treated with rSj16 were sequenced, analyzed and identified. Results: rSj16 attenuated clinical activity of DSS-induced colitis mice, diminished pro-inflammatory cytokine production, up-regulated immunoregulatory cytokine production and increased Treg percentages in DSS-induced colitis mice. Moreover, DSS-induced colitis mice treated with rSj16 displayed changes in the expression levels of specific genes in the colon and show the crucial role of peroxisome proliferator activated receptor a (PPAR-alpha) signaling pathway. PPAR-alpha activation diminished the therapeutic effects of rSj16 in DSS-induced colitis mice, indicating that the PPAR-alpha signaling pathway plays a crucial role in DSS-induced colitis development. Conclusions: rSj16 has protective effects on DSS-induced colitis, effects mediated mainly by PPAR-alpha signaling pathway inhibition. The findings of this study suggest that rSj16 may be useful as a therapeutic agent and that PPAR-alpha may be a new therapeutic target in the treatment of IBD.
