An n-tournament Tn is said to be a Kotzig tournament if the n subtournaments of Tn of order n − 1 are isomorphic. And a nonnegative integral vector R is said to be potentially Kotzig if there exists some Kotzig tournament Tn such that its score vector is R. In this paper, a criterion is found for determining whether a non-negative integral vector R is potentially Kotzig.
We ameliorate the original four-point scheme (called modified four-point scheme) and present the convergence discussion and error estimation. Meanwhile, we obtain the expression of derivative on the endpoints for the limit curve. Therefore, the split joint problem is solved.

orientation and formal methods are widely regarded as two fields with significant potential for new software engineering techniques. This paper discusses the relations between these two approaches. We present various specification techniques which incorporate object-oriented paradigms, discuss their place in software development process, and analyse possible benefits Replica Ghds For Sale

6 January 1984 marked the centenary of the death of that most notable Moravian scientist, Gregor Mendel. This article reviews the work of one of the most interesting men in the history of science, and attempts to gauge the nature of his thinking and his real role in the history of genetics and evolutionary science.
