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.
A gene pool is a collection of all the genes in a population. This can be any population-frogs in a pond, trees in a forest, or people in a town. A gene pool isn't a real place; it's an abstract idea or an imaginary collection. Let's look at an example to get a better understanding.
