In the paper, we suggest an approach to evaluate the number and composition of functional regions. Suggested approach is based on basic characteristics of functional regions, that are (1) more intensive intra-regional than the inter-regional interactions and (2) internal social and economic heterogeneity. Those characteristics are measured by factors estimated in spatial interaction model. The ...

background: intra-operative radiation therapy (iort) is the transfer of a single large radiation dose to the tumor bed during surgery with the final goal of improving regional tumor control. this study aimed to investigate the safety, effectiveness and economic evaluation of intra-operative radiation therapy.   methods : the scientific literature was searched in the main biomedical databases (c...

Constitutional arrangements in parts of the UK have been transformed by political devolution. In the English regions the Government has pursued a more cautious approach based upon reinforcing the regional tier through administrative decentralisation. Nonetheless, such reforms represent a significant strengthening of the machinery of regional governance and open up opportunities for the recalibr...

Intra-regional, extra-regional and international health mobility are important phenomena for regional and national healthcare planning. Pediatric data on this topic are scarce. We therefore conducted a systematic literature search on the PubMed database. Because of the insufficiency of published data we also resorted to conference proceedings and publications retrieved by Google Scholar and Goo...

The hypothesis of a complementary relationship in regional evapotranspiration allows for estimation of actual evapotranspiration on a regional scale by simple, physically based models that take into account feedbacks in land surface-atmosphere dynamics. A regional, seasonal Advection-Aridity model is used to create a monthly time-series of actual evapotranspiration for a period of 27 years at a...
