We present the results of a novel Mössbauer experiment in a rotating system, implemented recently at Istanbul University, which yields the coefficient k = 0.69 ± 0.02 within the frame of the expression for the relative energy shift between emission and absorption lines ΔE/E = ku2/c2. This result turned out to be in quantitative agreement with an experiment achieved earlier on the subject matter (Kholmetskii et al. Phys. Scr. 79, 065007 (2009)), and once again strongly pointed to the inequality k > 0.5, revealed originally in (Kholmetskii et al. Phys. Scr. 77, 035302 (2008)) via the re-analysis of Kündig’s experiment (Kündig, Phys. Rev. 129, 2371 (1963)). A possible explanation of the deviation of the coefficient k from the relativistic prediction k = 0.5 is discussed.

We discuss the results of modern Mössbauer experiments in a rotating system, which show the presence of an extra energy shift between the emitted and absorbed resonant radiation in addition to the relativistic energy shift of the resonant lines due to the time dilation effect in the co-rotating source and absorber with different radial coordinates. We analyse the available attempts to explain the origin of the extra energy shift, which include some extensions of special theory of relativity with hypothesis about the existence of limited acceleration in nature, with hypothesis about a so-called «time-dependent Doppler effect», as well as in the framework of the general theory of relativity under re-analysis of the metric effects in the rotating system, which is focused to the problem of correct synchronisation of clocks in a rotating system with a laboratory clock. We show that all such attempts remain unsuccessful until the moment, and we indicate possible ways of solving this problem, which should combine metric effects in rotating systems with quantum mechanical description of resonant nuclei confined in crystal cells.

AbstractAn extra energy shift between emitted and received radiation on a rotating disc – next to the conventionally recognised second-order Doppler shift – has been revealed in a series of recent Mössbauer experiments, where a radioactive source is fixed at the centre and an absorber is attached to the rim of the rotating disc. This disclosure gives indication to a possible violation of the “clock hypothesis” by Einstein: i.e. the independence of the rate of a clock on its acceleration. At the moment, there seem to be two plausible interpretations of this result: (i) the deviation of the geometry of the rotating disc from that predicted by the general theory of relativity (GTR), or (ii) the existence of a specific maximal acceleration in nature, when transformation between two accelerated frames differs from the corresponding transformation of the relativity theory. We take a closer look at both ways leading to the violation of the clock hypothesis; particularly, by analysing the outcomes of recent experiments in rotating systems and by suggesting a new Mössbauer rotor experiment to determine the most feasible mechanism for testing the dependence of the rate of a clock on its acceleration.

THE germ of that which follows came into being many years ago in the days of my youth as a university instructor and assistant professor. It was generated by the then quite outspoken attitude of colleagues in the “exact sciences”; the sciences of which the subject-matter can be exactly weighed and measured and the force of its movements mathematically demonstrated. They assured us that the study of languages and literature had little or nothing scientific about it because: “It had no domain of concrete fact in which to work.” Ergo, the scientific spirit was theirs by a stroke of “efficacious grace” as it were. Ours was at best only a kind of “sufficient grace,” pleasant and even necessary to have, but which could, by no means ensure a reception among the elected.

An outline has been presented in historical fashion of the steps devised to organize the central core of medical information allowing the subject matter, the patient, to define the nature and the progression of the diseases from which he suffers, with and without therapy; and approaches have been made to organize this information in such fashion as to align the definitions in orderly fashion to teach both diagnostic strategy and the content of the diseases by programmed instruction.

This article is aimed to examine the extent of the application of Islamic legal objectives by Sheikh Abdullah bn Fudi in his rejoinder against one of their contemporary scholars who accused them of being over-liberal about the religion. He claimed that there has been a careless intermingling of men and women in the preaching and counselling gathering they used to hold, under the leadership of Sheikh Uthman bn Fudi (the Islamic reformer of the nineteenth century in Nigeria and West Africa). Thus, in this study, the researchers seek to answer the following interrogations: who was Abdullah bn Fudi? who was their critic? what was the subject matter of the criticism? How did the rebutter get equipped with some guidelines of higher objectives of Sharĩʻah in his rejoinder to the critic? To this end, this study had tackled the questions afore-stated by using inductive, descriptive and analytical methods to identify the personalities involved, define and analyze some concepts and matters considered as the hub of the study.

Academic Qualifications

Performance is the performance shown by educators, both in quality and quantity in carrying out their duties in accordance with the responsibilities given to them professionally. Educator performance development is a very decisive factor in the success of the education and learning process. In fact, in Kindergarten Rayon IV, Dumai City, there is still a low level of competency standards possessed by educators. The intended competency standard is from the standard academic qualifications and four competencies that must be possessed by a kindergarten educator, namely pedagogic, professional, social and personality competencies. This is evidenced by educators not yet mastering learning material with the maximum known when the learning process educators are not able to explain well the subject matter, and educators have not shown maximum performance in carrying out their duties and functions. The purpose of this study was to see whether there was an influence on teacher professionalism on teacher performance in Dumai IV Rayon Kindergarten. The results of the study prove that there is a significant relationship between the professionalism of Kindergarten educators and the performance of educators in Kindergarten Rayon IV, Dumai City. This is evidenced by the value of Sig (2-tailed) professionalism on educator's performance of 0,000, so the calculation shows 0,000 <0.05. This means that Ha is accepted, that is, there is a significant relationship between the professionalism of Kindergarten educators and the Performance of Educators in Kindergarten Rayon IV, Dumai City.
