That is one of the reasons for the proliferation of ＂literary theories.＂ The notion is here placed between quotation marks because it does not mean the same thing to all the scholars in the field. Some regard it in the same way that theory functions in the sciences, where it focuses on the object it is associated with. For example, the atomic theory of matter is concerned with the internal constitution or the characterizing properties of matter. Others, however, are looking beyond the object towards the reader and the extra-textual environment. The approaches to literary studies which look beyond the individual work to outside phenomena are many and increasing all the time as new issues and concerns arrive on the social scene. Issues of climate change are fairly topical now; and criticism is already responding with such ideas as eco-criticism. The question of the identity of the literary object has to be kept in the front burner, so that it is not swamped by the many different interests which attach to literature from time to time. Bringing attention back to the literary work is the central concern of this paper; and we are doing this by way of the metaphors of perception often used with respect to the literary work as these suggest that the work is something to focus on, rather than to see through to something else. Finally, I elaborate the concept of integrity as an appurtenance of the literary text that attracts and holds the gaze.展开更多

Swirl-induced environmental burners(EV-burners), have notable features aligned with these requirements. In this study, an EV burner is investigated by both an ECT system and an OH-PLIF system. The aim is to detect the structure of a flame and obtain more information about the combustion process in an EV burner. 3D ECT sensitivity maps are generated for the measurement and OH-PLIF images are acquired in the same combustion zone as for the ECT measurements. The experimental images of a flame by ECT are in good agreement with the OH radical distribution pictures captured by OH-PLIF, which provide a mutual verification of the visualization method.展开更多

Comparing the calculated mass and radius related to each model with the data derived by the observations, we propose three possible internal structure models for Europa. All models are assumed to be differentiated into a metallic core, a (Mg,Fe)2SiO4 silicate mantle and an outer water shell. The only difference amongst these models are the composition of the core. The core of Model I is composed of Fe, while Model II composed of FeS, and the two models are based on the inferences provided by Europa's external gravitational field. Model III has a core which consists of Fe-FeS alloy, similar to that of Earth's outer core. Model I has a Fe core with a radius of 431 km, a (Mg,Fe)2SiO4 mantle with 999 km and a water shell with 132 km. Model II has a 777 km FeS core, a 619 km (Mg,Fe)2SiO4 mantle and a 167 km water shell. Model III has a 571 km Fe0.8(FeS)0.2 core, a 832 km (Mg,Fe)2SiO4 mantle and a 166 km water shell. In all three models, the density range and the radius of each layer is consistent with those deduced by Anderson et al.展开更多
