No full textCrisp and fuzzy advanced hierarchhy process for the design of an industrial building based timber and steel elements.
Get PDFSustainable Development (SD) emerged in the late 90’s, as a response to severe environmental problems worldwide and the public pressure they created. SD introduced the notion of environmental and social consequences of anthropogenic activity, affecting the paradigm of ’business as usual’ and increasing the complexity of design and implementation of new, environmentally and socially responsible, strategies. Decision making under these new coordinates has to tackle with both quantitative and qualitative information, as well as the relationship between the two. A combination of different knowledge domains, and the different methodological options they introduce, is necessary for tackling complex problems. This research focuses on this (new) challenge, specifically for the construction sector. Two methods, crisp and fuzzy Analytical Hierarchical Process (AHP), are used for the evaluation of the design of a (generic) industrial building. A decision making process is developed, where a problem hierarchy is created, expert knowledge is gathered and evaluated and final priorities of alternative solutions are produced, through a crisp and a fuzzy handling of data. The case study offers a first exploration, indicating the applicability and easy of use of the methods, presenting preliminary results and proposing further research trajectories
Cloning and Characterization of a Biotic-Stress-Inducible Glutathione Transferase from Phaseolus vulgaris
Get PDFGlutathione transferases (GSTs, EC 2.5.1.18) are ubiquitous proteins in plants that play important roles in stress tolerance and in the detoxification of toxic chemicals and metabolites. In this study, we systematically examined the catalytic diversification of a GST isoenzyme from Phaseolus vulgaris (PvGST) which is induced under biotic stress treatment (Uromyces appendiculatus infection). The full-length cDNA of this GST isoenzyme (termed PvGSTU3-3) with complete open reading frame, was isolated using RACE-RT and showed that the deduced amino acid sequence shares high homology with the tau class plant GSTs. PvGSTU3-3 catalyzes several different reactions and exhibits wide substrate specificity. Of particular importance is the finding that the enzyme shows high antioxidant catalytic function and acts as hydroperoxidase, thioltransferase, and dehydroascorbate reductase. In addition, its Km for GSH is about five to ten times lower compared to other plant GSTs, suggesting that PvGSTU3-3 is able to perform efficient catalysis under conditions where the concentration of reduced glutathione is low (e.g., oxidative stress). Its ability to conjugate GSH with isothiocyanates may provide an additional role for this enzyme to act as a regulator of the released isothiocyanates from glucosinolates as a response of biotic stress. Molecular modeling showed that PvGSTU3-3 shares the same overall fold and structural organization with other plant cytosolic GSTs, with major differences at their hydrophobic binding sites (H-sites) and some differences at the level of C-terminal domain and the linker between the C- and N-terminal domains. PvGSTU3-3, in general, exhibits restricted ability to bind xenobiotics in a nonsubstrate manner, suggesting that the biological role of PvGSTU3-3, is restricted mainly to the catalytic function. Our findings highlight the functional and catalytic diversity of plant GSTs and demonstrate their pivotal role for addressing biotic stresses in Phaseolus vulgaris
The effect of controlled atmospheres on the composition and quality of dill (Anethum graveolens L. cv. Ducat) cultivated in spring and stored at two temperatures
Get PDFThis study was performed to evaluate four atmospheres varying in CO2 and N2 concentrations on the composition and quality of dill (Anethum graveolens L. cv. Ducat) during storage. Seeds were sown directly in the soil on 16/01/2010 and the plants harvested 93 days after sowing. The leaves (lamina and petiole) were weighed
at harvest and immediately transferred to airtight plastic bags within which the atmospheres were modified by injection of O2, CO2 and N2. The treatments that were applied (O2-CO2-N2) were: (1): 20-0-80, (2): 20-5-75, (3): 20-10-70, (4): 20-15-65. All samples were stored for 14 days at 2 or 5°C and the gas composition within the bags maintained at the desired levels. From the results, it was found that weight loss during storage varied between 7 and 12% at 2oC and 13 and 17% at 5oC irrespective of the gas composition. Vitamin C concentration decreased during storage, but at both storage temperatures the decrease was less at the highest CO2 level. The concentration of total phenolics decreased during storage, irrespective of the composition of the storage atmosphere. There was a loss of chlorophyll during storage, which tended to be greater at 5oC than at 2oC, but was prevented at both
temperatures by the highest CO2 concentration. In consequence, leaves stored under a gas composition of 20-15-65 (O2-CO2-N2) were greener at the end of storage. This, in conjunction with the relatively higher vitamin C concentration in this treatment,
indicates that 15% CO2 was the most suitable storage atmosphere for quality retention in dill, while the preferred temperature was 2oC due to lower weight loss
