honing is a process for finishing surfaces to obtain smooth surface. this process is used for finalpolish of inner parts such as engines cylinders. optimizing this process has always been a bigchallenge for mass production of cylinder blocks of internal combustion engines. honing processhas some variable parameters, thus to get their optimum rates the automobile cylinders were tested.in this re...

This paper presents the details and relevant findings of an experimental program which was conducted in three phases to investigate the behavior of steel-concrete composite bridge girders strengthened with new high modulus carbon fiber reinforced polymer (HM CFRP) materials. In the first phase, the feasibility of various lIM CFRP strengthening systems was examined. The second phase investigated...

The aim of this article is to analyze nonlinear electro-magneto vibration of a double-piezoelectric composite microplate-system (DPCMPS) pursuant to the nonlocal piezoelasticity theory. The two microplates are assumed to be connected by an enclosing elastic medium, which is simulated by the Pasternak foundation. Both of piezoelectric composite microplates are made of poly-vinylidene fluoride (P...

In seeking a method for the routine observation of copulatory behaviour in rats we compared the use of a standard rectangular Makrolon cage, commonly used in toxicology studies, with a Plexiglas cylinder that provided 2.5 times more floor area. The cylinder resulted in a much higher incidence of copulation, either once or for multiple series, within 30 min. This was not affected by whether oest...
