There are two types of lithosphere: - Oceanic lithosphere, which is associated with Oceanic crust - Continental lithosphere, which is associated with Continental crust Oceanic lithosphere is typically about 50-100 km thick (but is no thicker than crust beneath the mid-ocean ridges), while continental lithosphere is about 150 km thick.
Pooling is a feature of SAS clients that increases the efficiency of connections to SAS. Pooling is only available for SAS Workspace Servers. When a SAS client application is configured to access a pooled workspace server, the client application maintains a collection of reusable workspace server processes called a pool. By reusing server processes, pooling avoids the processing that is associated with creating a new process for each connection. If your client application uses frequent, quick connections to SAS, pooling might greatly improve your server performance.
In insurance, the term risk pooling refers to the spreading of financial risks evenly among a large number of contributors to the program. Insurance is the transference of risks from individuals or corporations who cannot bear a possible unplanned financial catastrophe to the capital markets, which can bear them easily -- at least in theory.
