In this paper, we explore the interaction between taxation and local public good (LPG) and how it impacts the spatial pattern in the framework of new economic geography (NEG). In the benchmark case of a pure LPG, the system displays a similar location pattern to the existing NEG taxation model, although the tax reduces the market size of manufactured goods. However, when we consider the inheren...

BACKGROUND Mercury vapor poses a known health risk with no clearly established safe level of exposure. Consequently there is debate over whether the level of prolonged exposure to mercury vapor from dental amalgam fillings, combining approximately 50% mercury with other metals, is sufficiently high to represent a risk to health. The objective of our study is to determine if mercury exposure fro...

today as the land-filling of solid wastes without taking into consideration the environmental issues would threaten the land greatly, the selection of an appropriate site for hygiene disposal of the wastes is a necessity. analytic hierarchy process (ahp) is one of the most frequently used methods of multiple criteria choices. in site selection of an optimum place fro landfill in the city of bon...

We prove that many features of Thurston’s Dehn surgery theory for hyperbolic 3manifolds generalize to Einstein metrics in any dimension. In particular, this gives large, infinite families of new Einstein metrics on compact manifolds.

BACKGROUND The ICG filling is supposed to be faster than Fluorescein filling. Interestingly the filling characteristics of these dyes were never correlated directly using precise quantitative methods. Since ICG and Fluorescein are injected as a mixture, the simultaneous 2-channel angiography provides a suitable method to correlate the filling characteristics of the dyes. MATERIAL AND METHODS ...

This paper shows how standardization activities are progressing and contributing to the fact that Land Administration (LA) is considered more and more the cornerstone of the spatial information infrastructure. This is equally valid for regional, national, continental, and global levels, as will be illustrated in this paper. The paper describes the involved organizations and the current status o...

Future directions for spatial information management in Australia, from a land administration perspective, are discussed. Sustainable development, micro-economic reform, globalisation and technology are highlighted as the drivers for change. The changing spatial information environment with emphasis on land administration and cadastral issues is examined by drawing on research being undertaken ...

A graph G = (V, E) is called a pairwise compatibility graph (PCG) if there exists a tree T , a positive edge-weight function w on T , and two non-negative real numbers dmin and dmax, dmin ≤ dmax, such that V coincides with the set of leaves of T , and there is an edge (u, v) ∈ E if and only if dmin ≤ dT,w(u, v) ≤ dmax where dT,w(u, v) is the sum of the weights of the edges on the unique path fr...
