Two ages are attributed to each circular lunar sea, the age of formation of the circular basin, probably by impact, and the age of the filling of the basin by lava-like effusions.Each lunar-sea surface displays a range of geomorphic indices. This is interpreted as being due to the presence of effusions of different ages on the surface of each sea. The landing sites of Apollo 11 and 12 have geom...

Introduction: The geology of Terby Crater (28S, 287W), located on the northern rim of Hellas impact basin on Mars, is documented through geomorphic and stratigraphic analyses using all currently released visible and thermal infrared image data and topographic information. This large (D=164km), Noachian-aged [1] crater has a suite of geomorphic units [2] and landforms including massive troughs a...

The Kangerlussuaq area of southwest Greenland encompasses diverse ecological, geomorphic, and climate gradients that function over a range of spatial and temporal scales. Ecosystems range from the microbial communities on the ice sheet and moisture-stressed terrestrial vegetation (and their associated herbivores) to freshwater and oligosaline lakes. These ecosystems are linked by a dynamic glac...

The hydrology of a river basin interacts with its geomorphic form. Despite significant advances in hydrological modeling, the dynamic interactions between geomorphic, hydrologic and ecological processes are not adequately captured at the basin scale. There is a need for advanced modeling tools that address both runoff and erosion prediction in sufficient spatial and temporal detail for explorin...

Environment both endowed and built are essential for tourism. However tourism and environment maintains a complex relationship, where in most cases environment is at the receiving end. Many tourism development activities have adverse environmental effects, mainly emanating from construction of general infrastructure and tourism facilities. These negative impacts of tourism can lead to the destr...

Tourism is an important part of national economy. On the other hand it can also be a source of some negative externalities. These are mainly environmental externalities, resulting in increased pollution, aesthetic or architectural damages. High concentration of visitors may also lead to increased crime, or aggressiveness. These may have negative effects on quality of life of residents and negat...

We were interested to read Priya Shetty’s World Report examining the booming medical tourism industry in India (Aug 28, p 671). The Lancet is to be commended for bringing attention to this issue. It is of the utmost importance that trends in medical tourism be watched closely given the implications for patients’ health and safety and for health systems more broadly. Shetty places significant fo...

This article is a commentary of an overview on "medical tourism" submitted by Lunt and Marrion, which describes a framework for the study of the issues related to medical tourism. The commentary attempts to differentiate between the current interest in medical tourism and the time-honored and well-established treatment abroad from countries with underdeveloped health systems. The commentary als...
