A method is presented for the quick and accurate prediction of the stability of aerodynamically excited turbomachinery using real eigenvalue/eigenvector data obtained from a rotordynamics model. An expression is presented which uses the modal data and the transmitted torque to provide a numerical value of the relative stability of the system. This approach provides a powerful design tool to qui...

Koyun karbonik anhidraz-II (E.C: 4.2.1.1) enzimi koyun karaciğerinden saflaştırıldı ve bazı karakteristik özellikleri araştırıldı. Enzim 4000 EU/mg protein spesifik aktivitesi ve % 38.6 verim ile yaklaşık olarak 43,1 kat saflaştırıldı. Enzim için optimum pH, optimum sıcaklık, optimum iyonik şiddet ve stabil pH sırasıyla 7.5, 40oC, 10 mM ve 8.5 olarak belirlendi. Moleküler ağırlığı sodyum dodesi...

The Component Based Software Development (CBSD) is the new answer in the field of Software Engineering to the challenge of creating large software systems.Systems developed this way are more stabil, they have better quality, they are cheaper and meet better the requirements. This paper discusses the role and importance of Component Based Software Development in the evolution of Software Methodo...

In the title compound, [Cu(C(6)H(5)N(2)O(4))(2)], the copper(II) atom lies on an inversion centre and is in an N(2)O(2) four-coordinate environment with a nearly regular square-planar geometry. An extended network of intra-molecular O-H⋯O and inter-molecular N-H⋯O and C-H⋯O hydrogen bonds stabil-izes the crystal structure.

How do errors of measurement a ect a Delaunay triangulation of the measured points? We are given an `exact' and a `measured' set of points P and P 0, respectively, in the plane. The error of measurement is bounded above by ". Obviously, two Delaunay triangulations T of P and T 0 of P 0 may di er in their topologies. However, for certain edges of T we can guarantee that any `measured' triangulat...
