A new and significant source of information on earthquake studies has been provided by space geodesy. The data which are gathered by various techniques of space geodesy, can quantify potential of seismic activity in the region of interest. To achieve this goal, the main advantage of extra-terrestrial geodetic data in comparison with the conventional data from geology and seismology is the abili...

We discuss some ambiguities associated with the phrase \direct search method" and propose a formal deenition.

In this paper, the slipping friction is considered in the problem of a progressive wave of real fluids propagating over a permeable bottom.In the interface of soil and fluid, the “no-slip” condition is relaxed and a sliding friction coefficient is introduced. Thus, the slipping effect and the permeability of the bottom on the velocity near the seabed can be studied. The results indicate that th...

Attempts to predict the number of political parties emerging in democracies have usually been based on one of two seemingly incompatible approaches: ( 1 ) the ‘institutional’ approach (e.g.. Duverger’s Law and Hypothesis) focuses o n the nature of the electoral system and also on the number of seats per district: (2) the ‘ideological’ approach stresses the nature and extent of social cleavages....

IT outsourcing has three broad forms: (i) Single-Sourcing, where the client outsources to one primary vendor, (ii) Single-Sourcing with subcontracting , where the primary vendor involves other/secondary vendors in the project, and (iii) Multi-Sourcing, where the client outsources to multiple primary vendors. Using a dataset of large IT outsourcing contracts from the SCD database with 22,031 lar...

Congenital abnormalities of the ribs, including slipping or clicking rib, are well recognised but rarely give rise to symptoms. Slipping rib has previously been described as a unilateral condition. We report an unusual case of symptomatic bilateral slipping ribs treated successfully by surgery.
