The history of mathematics can be viewed as a counterpoint between the finite and the infinite, between the discrete and the continuous. Although rooted in geometry, Greek mathematics was primarily finite, concrete, and specific. Modern mathematics, in contrast , is infinite, abstract, and general. Aristotle in-veighed against the actual infinite, reflecting the Greek cultural distaste for the ...

Bangladesh is one of the smaller states in Asia. But it has a long and rich history of nuclear medicine for over sixty years. The progress in science and technology is always challenging in a developing country. In 1958, work for the first Nuclear Medicine facility was commenced in Dhaka in a tin-shed known as ‘Radioisotope Centre’ and was officially inaugurated in 1962. Since the late 50s of t...

In 1955, the first nuclear medicine division was established in Thailand by Professor Romsai Suwannik in the Department of Radiology, Siriraj Hospil, Mahidol University in Bangkok. In 1959 four years later, the second nuclear medicine division was established in the Department of Radiology, Chulalongkorn Hospital in Bangkok. The third nuclear medicine division was started in Rajvithi Hospital i...

Nowadays, Alcohol is widely used in medicine and industry. On the other hand, it is well-known for its intoxicant and addictive effects and they were common in the past. Discovery of it was imputed to Mohamad ibn Zakaria Razi (Rhazes, 925 AD) or Jaber ibn Hayan (Geber, 815 AD). The Islamic researchers’ viewpoint about alcohol and their knowledge about this substance are aimed to be explored in ...

this paper gives a short survey of some of the known results generalizing the theorem, credited to i. schur, that if the central factor group is finite then the derived subgroup is also finite.

in this paper, seismic behavior of the existing buildings equipped by friction dampers is studied. seismic performance of6-story, 9-story and 12-story steel buildings with damper and without damper were studied. the finite element modeling technique (sap2000 software) is used for analysis. time history analyzing was done to achieve this purpose. for nonlinear dynamic analysis, the responses of ...

in this study, mass, stiffness and damping matrices of the nosrat jacket; located in persian gulf; equipped with semi active tuned mass damper (satmd) system have been derived after modeling the structure in sacs software. owing to huge number of the degrees of freedom in the model, computation of on-line control of satmd was time consuming. for this purpose, the size of the model was reduced i...

This paper tries to examine literature as history, with an emphasis on the crucial role of fiction in narrating the marginalized events of history. Some fictions are actual accounts of events in history, and some are reflection of events. Actually, literature and history are integrated to each other, in a way that, pure history which shows us the reality and truth is just a myth. The pens writi...

In this paper, we recount the history of artificial viscosity, beginning with its origin in previously unpublished and unavailable documents, continuing on to current research ending recent work describing physical basis that suggests new directions for improvement. This review is mainly about finite volume methods scale theory, We focus underlying ideas recognize finiteness measurement.
