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...

in this study, a temperature-dependent of the dispersion coefficients is calculated from equation state.the lennard-jones lj (12-6-3) effective pair potential function and simple thermodynamic argumentwith the input pvt data of liquid metals are used to calculate the dispersion coefficients. the dispersioncoefficients ( , , ) 3 6 12 c c c are found to be a linear function of 1/t1+α , where t is...

Metal-pattern formation using vacuum evaporation is a critical process from basic research to industrial mass-production. Selective metal deposition metal-atom desorption an organic surface promising metal-patterning method by maskless deposition. In this study, we demonstrate metal-pattern for various species vacuum-depositable and printable perfluoropolyether (PFPE) based material. A PFPE-bas...

We developed an evolutionary epidemiological approach to understand the regional and world-wide dispersion of Yam mild mosaic virus (YMMV) by retracing its evolutionary history. Analyses of the distribution and the prevalence of YMMV in the Caribbean islands of Guadeloupe and Martinique, and in French Guyana revealed that YMMV has a wide repartition and different prevalence on Dioscorea alata L...

BACKGROUND Cardiac memory refers to the observation that altered cardiac electrical activation results in repolarization changes that persist after the restoration of a normal activation pattern. Animal studies, however, have yielded disparate conclusions, both regarding the spatial pattern of repolarization changes in cardiac memory and the underlying mechanisms. The present study was undertak...

The disposal of associated gases through flaring has been a major problem for the Nigerian oil and gas industries and most of theses gases are flared due to the lack of commercial out lets. The resultant effects of gas flaring are the damaging effect of the environment due to acid rain formation, green house effect, global warming and ozone depletion. This writes up is aimed at evaluating groun...

This thesis introduces the idea that a simulated interferogram can be used as a reference for an interferometer. This new concept represents a paradigm shift from the conventional thinking, where a reference is the phase of a wavefront that traverses a known path. The simulated interferogram used as a reference is called a virtual reference. This thesis develops the theory of virtual reference ...

ramadan fasting is one of the most important religious duties of muslims, that its effect on the heart has not been determined yet. our objective was to evaluate the effect of ramadan fasting on ventricular repolarization as assessed by qt interval, corrected qt interval, qt dispersion or corrected qt dispersion. sixthy healthy subjects aged 20 to 35 years were dispersion included in this study...

Seed dispersal permits the colonization of favorable habitats and generation of new populations, facilitating escape from habitats that are in decline. There is little experimental evidence of the factors that limit epiphyte dispersion towards their hosts. In a tropical dry forest in central Mexico, we monitored the phenology of dispersion of epiphyte species of the genus Tillandsia; we tested ...

During telencephalic development, a boundary develops that restricts cell movement between the dorsal cortical and basal striatal proliferative zones. In this study, the appearance of this boundary and the mechanism by which cell movement is restricted were examined through a number of approaches. The general pattern of neuronal dispersion was examined both with an early neuronal marker and thr...
