A T-type rectangular microchannel with a hydraulic diameter of 408μm was used. Operating parameters, i.e. temperature, pressure and molar ratio of MEA to CO2 were studied. Under 3 MPa pressure, the mole fraction of CO2 in gaslphase could decrease from 32.3% to 300×10-6 at least when gas hourly space velocity ranged from 14400 to 68600 h- and molar ratio of MEA to CO2 was kept at 2.2. In particular, the effects of temperature on CO2 absorption flux, mass transfer driving force, gas-liquid contact time and en- hancement factor were analyzed in detail and found that mass transfer enhancement by chemical reaction was a crucial factor for the orocess of CO9 absorotion.展开更多

Looked from the running situation of Wu Long kou sewage treatment plant, the improved oxidation ditch have certain advantages in city sewage treatment, such as high organic removing efficiency, good removing effect of nitrogen and phosphorus, low investing expenses and operating cost and so on. It is a craft that is worth promoting in urban sewage treatment.展开更多

This character which Heidegger, too, through a paradoxical convergence with Adorno, and in opposition to Lukacs, recognizes as its ontological component, permits the work of art to represent a force of resistance to dominance in general, in the prospect of the salvation of a humanized society. As such, it makes possible the radical rejection of political and, pertinent to it, pedagogical activity, when converted into primarily authoritiarian activity. Such a responsibility does art assume, according to Adorno, when it represents a spirituality, which is embodied in exemplary fashion both in the work of art itself, making the experience of the sublime possible, and in the aesthetic of the sublime, which is concentrated intensively on whatever remains unapproachable through concepts. In this way, we could say that the aesthetic of the sublime is converted into "first philosophy," in the sense that it provides the rule for every theoretical approach. Concurring with this reading of Adorno, we consider how the sublime, as shown in the context of his aesthetic theory, is governed, furthermore, by a paideutic principle of exceptional significance, which we must necessarily activate through aesthetic education, so that western man may understand that he must uproot himself from the nihilistic social context in which he lives, rupturing the delusion of his omnipotence. In a world governed by a permanent crisis of democracy in public and private life, since the weakening of political imagination unites with the retreat from political ethos and an generalization of the unprecedented will for dominance, we consider this aesthetic theory to be exceptionally essential and useful to us both as pedagogical theory and as political theory, since it allows us to understand that the experience of the sublime through art is in opposition to this condition of destruction, and indeed represents the ideal of justice.展开更多

In the course of historical development, ancestors of human beings created incomparable cultural heritage relics and spiritual civilization with their diligent hands and the great wisdom left us countless cultural heritage relics, many of them have become the famous wonder of the world. These civilizations and cultural heritage are located in Asia, Europe and America, Africa, for example, the Egyptian Pyramids, Acropolis in Athens. Mayan Civilization in Mexico, Mogao Grottoes of Dun Huang of China, Qin Terra-Cotta Warriors and Horses Figurines, Angkor Wat-Cambodia, Venice-ltaly, the Buddhas of Bamiyan in Afghanistan. The essay will mainly choose the 4 most famous representative cultural heritages worldwide to discuss their artistic characteristics, current situation and damage level and effective protective measures.展开更多

The Bionic Lizard Flying Wheel Planing Craft was created and invented. This paper describes the evolution, experimental investigation, test results, design features, advantages, applications, and prospect of the innovation, which denotes the craft with excellent speed performance (high speed, extra STOL (short take-off and landing distance) and VTOL(vertical take-off and landing) characteristics, good transverse and longitudinal stability, super shallow water draft, high propulsion efficiency at high speed without cavitations obstacle, low external field noise, small dimension, simple configuration and structure, good economy, nice transportation efficiency, and possibly is first of these kinds in the HPMV (High Performance Marine Vessels) family around the world.展开更多

Among the art-works of Fiumara d'arte, the Pyramid is the last one in order of time. It is a monumental sculpture made of COR-TEN steel, by the artist Mauro Staccioli and it is located on one specific point of the 38th parallel of latitude, on a hill of the northern mountains of Sicily. In this study the architectural and engineering features of land art-works built in this particular plein-air park are examined and discussed. After a general description of Fiumara d'Arte and its significance in the territory, the case of the Pyramid on the 38th parallel is focalized and a discussion of its architectural, artistic and environmental values is reported. Moreover the structural implications in its design and construction are explained, while the worst effects of external actions are underlined by showing the results of the analysis performed on a finite element model of the whole structure.展开更多

What historical and documental value can we attribute to the typological and technical aspects of military buildings? What problems and strategies have to be studied before such buildings can be repurposed for inclusion into a circuit of social and civil uses? Some attempts were made to answer these questions by analysing the military real estate of Palmanova, the fortress city founded by the Serenissima Republic of Venice in 1593, a city designed by engineers, military analysts, and expert military architects all answerable to the Fortifications Office of Venice. There are a number of barracks situated inside the city's fortified walls, within a somewhat confined area: Montezemolo, Isonzo, Ederle, Filzi, Montesanto and others in outlying villages. Barracks built in different periods (some during the Renaissance, others in the eighteenth century and some even after the Second World War) have been gradually phased out of service. Their restoration and functional leverage, in the early years of this century, were discussed in terms of an economic and cultural strategy that would not upset the city. New regeneration strategies are called for if these abandoned military structures are not to undergo further deterioration. These strategies should be based upon a knowledge of these structures' features--their layout, architecture, technologies--and should also embrace local policies, but first and foremost they require real, contextualized and economically sustainable projects.展开更多

Cemetery is one of the sites where people could give way to their subjective comprehension of beauty. Analysis of the cemetery planting revealed certain noticeable features that could be ascribed to the forms of folk art. These are various objects with implied specific content or ornamented compositions. The aim of the research was to ascertain and distinguish graves characterised by specific planting features associated with plants, their layouts on graves. Analysis of the research results shows that two options form the peculiarities of grave planting: depiction of specific objects and ornamentation.We think that majority of the ornaments are made with the single purpose of decoration, and do not associate with symbolic meanings. During this research the graves decorated with planted symbolic objects and ornaments were distinguished. This phenomenon becomes more and more popular in cemeteries of Siauliai city in Lithuania.展开更多
