The electron density applications available within QUANTA96 represent novel and effective tools for speeding up the processes of Cα tracing experimental maps and manual rebuilding during refinement. The various modules (XAUTOFIT, X-BUILD, X-SOLVATE and XLIGAND), have been developed over the past year in close collaboration with the large number of crystallographers working on projects in the Pr...

an agroecological zones (aez) map is an essential tool for agricultural planning. by integrating the key components of the agricultural environments, it offers a bird's-eye view of internal diversity, agricultural potential and constraints that decision-makers find easier to understand than a pile of single-theme maps. in this study, aez map of the karkheh river basin has been prepared usi...

Mapping agencies world-wide produce a range of different types of maps, in efforts to meet different user requirements. These maps are usually designed in a digital environment and some of them are distributed through the World Wide Web. One important issue for those agents is the appropriate modelling and handling of map objects from which the digital maps are composed. , This paper focuses on...

An archimedean vector lattice A might have the following properties: (1) the sigma property (σ): For each {an}n∈N ⊆ A there are {λn}n∈N ⊆ (0,∞) and a ∈ A with λnan ≤ a for each n; (2) order convergence and relative uniform convergence are equivalent, denoted (OC⇒ RUC): if an ↓ 0 then an → 0 r.u. The conjunction of these two is called strongly Egoroff. We consider vector lattices of the formD(X)...

We introduce several new kinds of inferior and superior limits and corresponding kinds of semicontinuity of a set-valued map. Together with the known concepts of semicontinuity, they can be used to have a clearer insight of local behaviors of maps. Then we investigate all major semicontinuity properties of solution maps to a general quasivariational inclusion. Consequences are derived for sever...
