The structures of three xGeO(2)-(1- x)P(2)O(5) glasses, where x = 0.98,0.88, and 0.81, have been studied by neutron and x-ray diffraction experiments that yield well resolved P-O and Ge-O bond distances. The Ge-O coordination number (N(GeO)) increased from 4.0 ± 0.2 to 4.5 ± 0.2 with the decrease in x from 0.98 to 0.81. The increase in N(GeO) is consistent with a structural model that assumes t...

3D geo-database research is a promising field to support challenging applications such as 3D urban planning, environmental monitoring, infrastructure management, and early warning or disaster management and response. In these fields, interdisciplinary research in GIScience and related fields is needed to support the modelling, analysis, management, and integration of large geo-referenced data s...

Unsettled maritime boundaries can hinder economic exploitation of offshore resources and complicate the management borders. They thwart states from getting on path prosperity progress. This article explores factors which when taken together makes most likelihood effective border in WIO. It uses descriptive-analytical method qualitative research to conduct retrospective analysis. The paper highl...

extended abstractintroductionafter the cold war, geostrategic face took on a geo-economic domain. this means that on the world stage, economic competition, replaced military competition. hence the geopolitical divisions, geographic areas classified according to their economic importance and competition has intensified around the area. given that the earth is 4/3 with water and based on the theo...

In the last 30 years, China’s economic power has experienced great changes and has brought about a profound impact on the world economy. This led us to ask a question: do changes in China’s economic power shift the geo-economic relationships between China and its neighboring countries? To answer this question, we researched the evolution of geo-economic relationships between China and the Assoc...
