Studies on the effect of heavy oil spilled from the wrecked Russian Tanker "Nakhodka" on the growth of plants

Many interesting graphs are obtained from combining pairs (or more) of graphs or operating on a single graph in some way. We now discuss a number of operations which are used

2 Combining the lemma 5.4 with the main theorem of [SW1], we immediately obtain the following corollary.. Corollary 5.5 Let l > 3 be

This paper is devoted to the investigation of the global asymptotic stability properties of switched systems subject to internal constant point delays, while the matrices defining

In this paper, we focus on the existence and some properties of disease-free and endemic equilibrium points of a SVEIRS model subject to an eventual constant regular vaccination

Classical definitions of locally complete intersection (l.c.i.) homomor- phisms of commutative rings are limited to maps that are essentially of finite type, or flat.. The

We study the classical invariant theory of the B´ ezoutiant R(A, B) of a pair of binary forms A, B.. We also describe a ‘generic reduc- tion formula’ which recovers B from R(A, B)

After performing a computer search we find that the density of happy numbers in the interval [10 403 , 10 404 − 1] is at least .185773; thus, there exists a 404-strict
