β¦ Synopsis
In this paper we prove some existence theorems of multiple periodic orbits of Hamiltonian systems on a class of hypersurfaces in R 2n that are more general than star-shaped ones. Our results extend some earlier works on this subject.

In this paper we study the existence of positive almost periodic solutions for a class of almost periodic LotkaαVolterra type systems with delays. Applying Schauder's fixed point theorem we obtain a general criterion of the existence of positive almost periodic solutions. This criterion can be used
The constants of thermolysis rate of C,H,~(CH,),~O~(CH,),-C6HS ethers were measured in conditions close to those of coal liquefaction (hydrogen pressure of 8.5 MPa; temperature up to 410Β°C) but minimizing secondary conversions (i.e. in ten-fold excess of tetralin). The ethers form the following reac
