I argue that the science of aesthetics is deterministically visual. Drawing from theories of landscape aesthetics put forth by Carlson and Berleant, I outline four primary obstacles to an embodied aesthetics： plants as objects of sight, plants as objects of art, plants as objects of disinterestedness and plants as objects of scientific discourse. A multi-sensorial aesthetics of flora requires auto-centric proximity and degrees of intersubjectivity between the appreciator and the appreciated plant that raise important philosophical questions about aesthetic experience of the natural world.展开更多

This behavior is related to the volumetric instability when the water content is changed. Natural collapsible soils in Brazil are generally found in alluvial, colluvial and residual soils. There are known occurrences of natural collapsible soils in many states of Brasil. In the last two decades, many public projects have been developed in areas where the occurrence of collapsible soils has been associated to geotechnical problems. The present paper devoted to study the collapsible soils in the state of Pernambuco which has been associated with large engineering projects such as housing and irrigation canals. The geotechnical investigation program included test with a field apparatus, called Expanso-colapsometer, which allows the measurement of the field settlements of a small 0.10 m of diameter plate inserted at any depth inside an auger boring hole. Reconnaissance borings with SPT （standard penetration test）, investigation pits with undisturbed block sampling and disturbed samples for laboratory tests were also made in order to assess the type and characteristics of the soil. Field tests used the Expanso-colapsometer to measure the settlement of the soil in selected depths under controlled flooding. Laboratory work included double and standard oedometer tests with a controlled rate of water inflow of 1.0 mL/s. It was found that the volume change of the soils when flooded depends on their natural stress state （vertical stress, suction head and structure of soil）.展开更多
In this paper, we consider Cauchy problem for a class of quasilinear hyperbolic equations with forced terms, extend and improve the existence in paper[2].
