Abstract
Purpose
The purpose of this paper is to study the dynamical properties of a rotating rigid body (RB) containing a viscous incompressible fluid.
Design/methodology/approach
The Reynolds number is assumed to be small so that the governing equations can be easily obtained, and the asymptotic technique is used to solve the problem.
Findings
The effects of the various body parameter values on the motion’s behavior are theoretically elucidated, which can be used for optimization of the charged RB.
Originality/value
This paper finds the missing piece of the puzzle when it comes to the rotating RB containing a viscous fluid; it clearly elucidates graphically how the body parameters affect its dynamical properties.

Abstract
Metal Industries Ltd. Changes in the Metal Industries Ltd. board of directors have taken place owing to the decision of R. W. McCrone to retire, after 33 years as managing director and more recently as chairman, in order to devote himself more freely to other interests. The directors will recommend his appointment as one of the honorary presidents of the company. He will be succeeded as chairman by J. S. Hutchison.

Abstract
Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract
This paper gives a bibliographical review of the finite element methods (FEMs) applied to the analysis of ceramics and glass materials. The bibliography at the end of the paper contains references to papers, conference proceedings and theses/dissertations on the subject that were published between 1977‐1998. The following topics are included: ceramics – material and mechanical properties in general, ceramic coatings and joining problems, ceramic composites, ferrites, piezoceramics, ceramic tools and machining, material processing simulations, fracture mechanics and damage, applications of ceramic/composites in engineering; glass – material and mechanical properties in general, glass fiber composites, material processing simulations, fracture mechanics and damage, and applications of glasses in engineering.

Abstract
The very headline of this presentation hints at least two things. First, what is meant is the history of American sociology, though it is some what awkward to say so outright. Second, the history of American sociology is accomplished, in an impor tant sense, but one should not say that so out‐right, either. In philosophy, as Wittgenstein advised, whereof we can not speak, thereof we must be silent. A different rule reigns in sociology: whereof we can hint at, thereof we must prove. My first task, there fore, is to prove that no matter how embarrassing it may seem one canspeak of a his tory of American sociology after all. My second task is to prove that it has already been on a course of development specifically characteristic of it. And, finally, my last point will be that this specific course is brought to its desired end. Every thing in its own time. Talking about the history of American sociology is extremely risky. But it is the risk that it makes it worth trying. Part of the risk stems from the issue if there is a history of sociology at all, as well as from the issue if there is American sociology in the proper sense of the word. Apart from this, there is the consideration that it may be the American nature proper of that sociology that makes it the least likely to have its own history. First things first.

Abstract
This article’s indented contribution is to provide novel theoretical insights and empirical observations on “who gets what” in the way of incomes, including wages. The article challenges the conventional wisdom about stratification, especially power and status, as an outcome or function of economic distribution. It posits that income distribution is conditional on pre‐existing social stratification expressed in antecedent differences in class, power, status and related factors.

Abstract
Five leading abstracts services in the field of documentation were inspected. A measure of their coverage was obtained by matching the items of a bibliography against each service. All abstracts published by these services in 1964 were counted and ranked to estimate the scope of each service, to identify key journals and to assess the language problem. Leading journals were also identified by counts of citations following articles in nine leading documentation journals, mostly over a five‐year period. These citations were ranked in the same way as the abstracts in order to further identify key journals and to provide another view of the language barrier.
