F Ring

ABSTRACTSaturn's broad E ring, the narrow G ring and the structured and apparently time variable F ring(s), contain many micron and sub-micron sized particles, which make up the “visible” component. These rings (or ring systems) are in direct contact with magnetospheric plasma. Fluctuations in the plasma density and/or mean energy, due to magnetospheric and solar wind processes, may induce stochastic charge variations on the dust particles, which in turn lead to an orbit perturbation and spatial diffusion. It is suggested that the extent of the E ring and the braided, kinky structure of certain portions of the F rings as well as possible time variations are a result of plasma induced electromagnetic perturbations and drag forces. The G ring, in this scenario, requires some form of shepherding and should be akin to the F ring in structure. Sputtering of micron-sized dust particles in the E ring by magnetospheric ions yields lifetimes of 102to 104years. This effect as well as the plasma induced transport processes require an active source for the E ring, probably Enceladus.

Structured Population Dynamics

We present results of the numerical investigation of the homogenous Dirichlet and Neumann problems to an age-sex-structured population dynamics deterministic model taking into account random mating, female’s pregnancy, and spatial diffusion. We prove the existence of separable solutions to the non-dispersing population model and, by using the numerical experiment, corroborate their local stability.

The Ideal

Introduction. The work of many employees in the service sector is associated with a constant stay in a forced working position sitting at the computer for up to 60-80% of the time of the entire work shift, which leads to fatigue. The rate of fatigue depends on the specifics of work: it is much more likely to occur when working with monotony, muscle tension. An important role in the appearance of fatigue is also played by the attitude of a person to the work performed. The aim of study is to study the motor activity of knowledge workers in social service centers for the development of preventive measures aimed at reducing hypokinesia and hypodynamia during the work shift. Materials and methods. The following methods were used in the study: questionnaire and working day timing, calculation methods to determine whether the actual body weight corresponds to the ideal one using the Broka’s index and the Ketle’s index. The study involved employees of the integrated social service center "Raduga" in Bugulma. Results. An assessment of the motor activity of employees of the social service center of the population was made, and it was concluded that the problem of hypokinesia and hypodynamia is relevant and significant for employees of social service centers of the population both in their daily activities and during the work shift. Most of the employees showed an increase in actual body weight compared to the ideal one, which is to some extent due to hypokinesia and hypodynamia both during the working day and at home. Conclusions. Preventive measures aimed at compliance with the principles of rational nutrition and a healthy lifestyle, work and rest regimes, high-quality preliminary and periodic medical examinations are proposed.

Muslim Scholars

The levels of knowledge hierarchy (i.e., data, information, knowledge, and wisdom), are described in the Qur’an, the ahadith, and the literature produced during Islamic civilization’s Golden Age. They also have been discussed by western and non-Muslim scholars. However, while implementing and using information and communication technology (ICT), only the first three levels are currently being explored and utilized. Wisdom has not been discussed to any great extent. ICT has designed systems to assist us and has improved our life and work. However, such tools as decision-support systems and executive information systems comprise only data, information, and knowledge. Comprehensiveness does not guarantee the possession of wisdom. Taking things apart is knowledge; putting things together is wisdom. Muslim scholars of the Golden Age analyzed data, drew relationships and interpreted data to create information, identified and determined the pattern to represent knowledge, and understood the foundational principles for the patterns to implement wisdom. Wisdom must be included if ICT is to be complete. People, organizations, and the nation must strive for wisdom as the ultimate goal: from an information society to a knowledge society to a wisdom society, and from information workers to knowledge workers to wisdom workers.
