This note discusses the Timoshenko–Ehrenfest beam theory and the Griffith fracture theory. Both were annunciated in the West in 1921, exactly a century ago. Much progress has been made in these fields. Discussing the deficiencies of the theories might pave way ahead.

The seismoacoustical investigations was made in the western part of the Kerch strait (Azov sea) near Kamysh-Burun spit. The fracture zone with dislocated sedimentary rocks layers and buried erosional surface was revealed to the west of spit. Three seismofacial units was revealed to the east of spit. The first unit was modern sedimentary cover. The second ones has cross-bedding features and was, probably, the part of early generation of Kamysh-Burun spit, which lied to the east of its modern position. The lower border of the second unit is the erosional surface supposed of phanagorian age. The third unit is screened by acoustic shedows in large part.

The relationships between Islam and the West are complex. Even theperceptions of those relations have an important impact on the nature ofthe interactions. If the basic images that are used in discussing “Islam andthe West” are themselves ill-defiied or viewed in inconsistent ways, therelationships themselves are affected in sometimes dangerous ways.Inconsistent and contradictory terms of analysis can lead to misunderstandingand conflict.One of the most frequent conceptual mistakes made in discussingIslam and the West in the modem era is the identification of “the West”with “modemity.” This mistake has a significant impact on the way peeple view the processes of modernization in the Islamic world as well as onthe way people interpret the relationships between Islam and the West inthe contemporary era.The basic generalizations resulting from the following analysis can bestated simply: 1) “modernity“ is not uniquely “western”; 2) “the West” isnot simply “modernity”; and 3) the identifixation of “the West” with“modemity” has important negative consequences for understanding therelationships between Islam and the West. Modernity and the West aretwo different concepts and historic entities. To use the terms interchangeablyis to invite unnecessary confusion and create possible conflict’andinconsistency. This article will address the problem of definition and theapplication of the defined terms to interpreting actual experiences andrelationships.Understanding the difficulties raised by the identification of theWest with modernity involves a broader analysis within the frameworkof world history and global historical perspectives. In such an analysis, ...

AbstractNot everything that is logically possible and technically feasible is also natural, for example, placing China in the exact center of a world map. Such a map would not correspond to the laws of perception.Matteo Ricci, who was the first to create Chinese world maps on which the Americas were depicted, had to choose between two ideals, between a world map that obeys the gestalt principles of perception and a world map with the “Central State” China in its center. The first ideal mattered more to him than the second, although he took the latter into account as well. The result was a Pacific-centered map.Since we live on a sphere, what we perceive to be in the East and in the West depends on our location. It is therefore natural that in East Asia, world maps show America in the East and not – as in Europe – in the West. This was the argument underlying Ricci’s creation of Pacific-centered maps, and not the intention of depicting China as close to the center of the map as possible.It is only in East Asia that Ricci was the first to create Pacific-centered maps. World maps with the Pacific in the midfield were made in Europe before Ricci, motivated by the traditional unidirectional numbering of the meridians (0°–360°) from West to East starting with the Atlantic Insulae Fortunatae (Canary Islands).

Introduction.—The systematic exploration of Ptolemais (modern Tolmeita), in Cyrenaica, began in 1935 under the auspices of the Italian Government, and under the direction of the first-named writer. The general programme of excavation took into consideration not only the important Hellenistic period, which gave the city its name and saw its first development as an autonomous trading-centre, but also the late-Roman age when, upon Diocletian's reforms, Ptolemais became capital of the new province of Libya Pentapolis and a Metropolitan See, later occupied by Bishop Synesius.As one of several starting-points for the study of this later period, there was selected the area first noted by the Beecheys as containing ‘heaps of columns’, which later yielded the monumental inscriptions of Valentinian, Arcadius, and Honorius, published by Oliverio. Here excavation soon brought to light a decumanus, running from the major cardo on the west towards the great Byzantine fortress on the east. Architectural and other discoveries made in 1935–36 justified the provisional title ‘Monumental Street’ assigned to this ancient thoroughfare. In terms of the general town-plan, which is extremely regular, this street may be called ‘Decumanus II North’, since two rows of long rectangular insulae separate it from the Decumanus Maximus leading to the West Gate, still erect. The clearing of the Monumental Street and its frontages revealed the well-known Maenad reliefs, attributed to the sculptor Callimachus, a late-Roman triple Triumphal Arch, and fragments of monumental inscriptions similar in character to those previously published from the same area.

This study is mainly based on my work in psychiatry in the Clinic of Nervous Disorders, Khartoum North, and with my private practice patients. I have seen altogether 2,160 patients. The distribution of psychiatric illness in these is shown in the table below. The two populations of patients attending the Government clinic and private practice are comparable, and the same patients interchange. A comparison is made in this paper between psychiatry in the West, mainly British psychiatry, and Sudanese psychiatry.

Incidence and prevalence of infected Covid-19 are still rampant in the West and the most countries throughout world from 2020 to 2021. Although the incidence of infected Covid-19 in the developed countries has decreased down by the popular vaccination, it is still anxiety and worry to make more serious widespread from the variated coronavirus. It is a rigorous fact that there still are higher on the mortality to the seniors, special seniors who are resided at nursing homes. For seniors, the infected Coronavirus may product them a disastrous attack according to their pre-existing diseases, complication accompanied with Covid-19, and post-syndromes caused by Covid-19. Their Covid-19 may be more complex, more serious, harder to find a fast and effective therapies and easier to become to the post-syndromes which will make a bad influence to the quality of life in the rest of their life. TCM focuses to individual case, and pay attention more for their pre-existing diseases, complication with Covid-19, and possibility of post-syndrome’s production while some anti-coronavirus herbs are prescribed, so a more fixed prescription is made. In this clinical trial, the author classified 60 cases into two groups: over 45 years old as the observing group and under of 44 years old as the contrasted group, incidences on pre-existing diseases, complication and post-syndromes are observed separately; their results after treated by Chinese medical herbs are also observed. We recognize from these observation and analysis TCM treatment can significantly stabilized pre-existing diseases, treat complication together and prevent the post-syndromes’ occurrence while is treating to Coronavirus. TCM is a suitable treating choice to Senior with Covid-19.

Made in Yugoslavia: Studies in Popular Music (edited by Danijela Špirić Beard and Ljerka Rasmussen) is a fascinating study of how popular music developed in post-World War II Yugoslavia, eventually reaching both unsurpassable popularity in the Balkans and Eastern Europe, and critical acclaim in the West. Through the comprehensive discussion of all popular music trends in Yugoslavia − commercial pop (zabavna-pop), rock, punk, new wave, disco, folk (narodna), and neofolk (novokomponovana) − across all six socialist Yugoslav republics, the reader is given the engrossing socio-cultural and political history of the country, providing the audience with a much-needed and riveting context for understanding the formation and the eventual demise of Tito’s Yugoslavia.
