Whether a mild irritant （a ＂fly in the ointment＂）, a costly pest to gardeners （＂bug of W＂）, or a destructive force of Biblical proportions （a swarm of locusts）, bugs are nature＇s warning of approaching death. This paper investigates the natura morta canvas during the Golden Age of Dutch art, focusing on how these symbols of natural evil work to enliven the visual rhetoric of the still-life as they invite spiritual contemplation. In religious-themed art, we intuitively recognize these morbid creatures as symbols of decay encroaching on domestic scenes filled with food and cut flowers. Emphasizing the short life of these perishables, bugs embody a classic tension and its dichotomous variations： the corporeal vs. the spiritual, earth vs. heaven, and sin vs. redemption. Though ostensibly a peripheral feature of the natura morta, bugs are a decidedly central motif that reflects the viewer＇s struggle with sin： Is it repellent, attractive, or repellently attractive？ This study will concern the visual rhetoric of flies, dragonflies, and bees in the works of Osias Beert, Ambrosius Bosschaert, and Georg Flegel, with an emphasis on the beasts of the devil as icons of Dutch art.展开更多

This study includes a preliminary analysis of chemically treated water in existing concrete structures, and another after the application of the method and using materials for the structures in future. One of the priorities was to examine the existing concrete structures by using nondestructive and destructive methods. After that, based on the results of the analysis, adequate new materials are proposed for the repairs, most commonly new technology polymer carbonated materials, in order to achieve durability of structure elements in using technological processes. Behavior of the repairing structures was tested using the in situ methods, and especially pull-of test, to verify the adhesion force between the old concrete structures and new applied layer. After the repairing, the concrete structures will be monitored to record the behavior under the chemical treated water.展开更多
