In this paper we prove the existence of solutions for the nonlinear hyperbolic system of conservation laws in several space variables provided that the initial data are very close to each other. We also give an example and discuss the existence of solutions for large initial data.

Co-planar PCBs를 분석한 결과 붕어와 양서류 모두 전 지점에서 검출되었으며, 최대값은 황소개구리에서 1.622 pg-TEQ/g으로서 붕어의 최대값 0.974 pg-TEQ/g 보다 높게 나타났다.

A graph is k-cyclable if given k vertices there is a cycle that contains the k vertices. Sallee showed that every finite 3-connected planar graph is 5-cyclable. In this paper Sallee's result is extended to 3-connected infinite locally finite VAP-free plane graphs containing no unbounded faces.

In this article, we prove that a properly embedded minimal surface in $R^3$ of genus zero must be one of Riemann's minimal examples if outside of a solid cylinder it is the union of planar ends with the same torques at all integer heights.

The effectiveness of field plate and window tapering in reducing the maximum surface electric field of planar pn junctions has been studied by two dimensional computer simulation. The influence of silicon dioxide insulator thickness is also presented.
