Co-Operation in Island Biogeography

2000
In this chapter I discuss another example of co-operation of holistic and reductionistic research programmes in ecology.1 The example concerns some developments in island biogeography, a branch of ecology dealing with the distribution and abundance of species on islands.

Bathurst Island Group and Byam Martin Island, Arctic Canada (operation Bathurst Island)

1972
The Bathurst Island group, and Byam Martin Island, together occupy about 8,000 square miles of land area. They are situated near the geographic center of the Canadian Arctic Archipelago and encompass the north magnetic pole. Most of the area is covered by sedimentary rocks of Ordovician to Late Devonian age, with a composite exposed thickness of ...

Rotated Island Graft Operation for Pterygium

American Journal of Ophthalmology, 1926
This operation isolates the bulk of the pterygium by four incisions. Sutures are introduced in such a way as when tightened to rotate the isolated square 90 degrees. It is fixed in position with the help of additional sutures if needed. The operation is applicable only to exceptionally severe cases, which may have not been corrected by other operations.

Trackless Trolley Operation In Rhode Island

Transactions of the American Institute of Electrical Engineers, 1949
This paper attempts to set forth the knowledge gained in operating a growing trackless trolley system over a period of 17 years. It in no way is intended to prove that the trolley coach is a cure-all for transit ills. Unbiased transit experts recognize the need for all types of vehicles in the industry: ``A place for every vehicle-every vehicle in its ...

Research Operations on Jan Mayen Island

2004
The remoteness of Jan Mayen Island makes it rather inaccessible for scientists and the ruling arctic conditions require logistics that secure conditions for field research. The scope of research interests ranges from Global climate and hemispheric meteorology, seabed tectonics and volcanology, and geophysics of the World Ocean and the proximal Nordic ...

Distributed generation operation: Grid-connected vs. Islanded

2014 IEEE PES T&D Conference and Exposition, 2014
There are reasons when it might be desirable to utilize one or more DG resources to continue to provide power to a facility or group of facilities when the utility is unavailable, such as during major storms. There is an increased demand for formation of microgrids having their own self-contained generation that can continue to operate as an island in ...

Operational Lessons of the Line Islands Experiment

1967
This report reproduces the introspective review meeting about operational lessons learned from the Line Islands experiment that took place during March and April 1967. Observation groups on land, by air, and by sea, collaboratively collected one of the most comprehensive sets of meteorological data ever obtained in the tropics. Because the Line Islands

Research Operations in Remote Arctic Islands

2004
Conducting research in the remote and inaccessible parts of the Globe often demands specific logistical actions. Long-term research programmes are thus usually carried out by permanent research teams working in particular stations. The working conditions under such circumstances frequently fall short of the standards set for the average research ...
