Abstract In this work an analysis of the radial stress and velocity fields is performed according to the J 2 flow theory for a rigid/perfectly plastic material. The flow field is used to simulate the forming processes of sheets. The significant achievement of this paper is the generalization of the work by Nadai & Hill for homogenous material in the sense of its yield stress, to a material with general transverse non-homogeneity. In Addition, a special un-coupled form of the system of equations is obtained where the task of solving it reduces to the solution of a single non-linear algebraic differential equation for the shear stress. A semi-analytical solution is attained solving numerically this equation and the rest of the stresses term together with the velocity field is calculated analytically. As a case study a tri-layered symmetrical sheet is chosen for two configurations: soft inner core and hard coating, hard inner core and soft coating. The main practical outcome of this work is the derivation of the validity limit for radial solution by mapping the “state space” that encompasses all possible configurations of the forming process. This configuration mapping defines the “safe” range of configurations parameters in which flawless processes can be achieved. Several aspects are researched: the ratio of material's properties of two adjacent layers, the location of layers interface and friction coefficient with the walls of the dies.

This paper reports on promoting and enhancing effective teacher professional development in Tanzania: Lessons from Chinese teacher professional development. Teacher professional development is an important aspect in any country for educational achievement. In several years Tanzania has been facing ineffective teacher training and professional development. As a result, most of the teachers fail to plan their professional development as it expected to be. The analysis of findings indicated that Chinese teacher professional development has obtained significant achievement due to the presence of a strong policy, heavy investment in the teacher education sector, and other related factors. In this regard, these lessons are worth to Tanzania which still struggling to have effective teacher professional development through teacher practice. Therefore this study recommended that the Tanzanian government should encourage professional training programs for teachers through financial and material support.

Carl Ritter von Ghega was proclaimed 2018 Surveyor of the Year on 21 March 2018. In this paper, we explore how this Austrian of Albanian extraction, born in Venice, played an important role in geodesy and the surveying profession and the honours he got up to the present day. We investigate his background and details of his professional path, education and most important contributions in the areas of surveying and engineering at large. We describe his most significant achievement, that is, the Semmering Railway, which was dismissed at the time as impossible to achieve. In 1998, the Semmering Railway was inscribed in the UNESCO World Heritage List. Apart from this project, which left a great impression on the engineering profession, von Ghega also developed the Borovnica Viaduct built in the mid-19th century in Slovenia.

ABSTRACT This research was carried out to know the effectiveness of implementing KWL strategy to improve students’ reading comprehension of report text and to know whether there is a significant achievement difference between students who were taught with KWL strategy and those who were not. The instrument used was a multiple choice reading comprehension test. Seventy two eleventh graders of SMA Negeri 1 Bae Kudus were selected as the sample. They were divided equally into experimental and control group. The data collection involved pre-test, treatments, and post-test. The result of the implementation of KWL strategy in the experimental group improved the students’ participation, motivation, and interest during teaching and learning process. In addition, the results of pre-test and post-test showed that mean score of the experimental group had a higher increase from 74.58 to 90.97 than the control group (from 72.77 to 87.77). However, the Independent Sample Test showed there was no significant achievement difference between the students who were taught with KWL strategy and those who were not.

The book (Un)forgotten documentalists, edited by Katarzyna Mąka-Malatyńska and Jolanta Lemann-Zajiček (2020) is a significant achievement in research on Polish documentary film. The review of the collective work, consisting of ten texts preceded by an introduction, becomes the starting point for discussions with selected authors and reflection on the problem of the absence of significant documentary filmmakers in the history of the film. Entire currents are also forgotten, such as a film about art, represented by four out of nine documentary filmmakers discussed in the book. The meanders of life and creativity can be instructive for contemporary documentary filmmakers.

On December 1, 1920, General Álvaro Obregón of Sonora became President of Mexico. During the previous May, his supporters had staged a popular coup d'etat which paved the way for his constitutional election. Mexico was then in the throes of revolutionary ferment, and the instability which had accompanied Obregón's ascendancy to Executive Office also threatened to attend his demise. Obregón thus sought to achieve political and social reforms which would strengthen his regime and allow for a peaceful Presidential succession in 1924. As the major institution of coercion during a time of revolutionary violence, the Army had emerged as the most important political institution in Mexico. Although part of a broader political effort which included labor, agrarian and administrative reforms, Obregón's military reconstruction can be viewed as the important keystone in his attempt to consolidate control of Mexico. Obregón’s military reforms sought to insure, first, Army loyalty to the office of President, and, second, military effectiveness when the Army would be called upon to defend the Federal Government. His reforms grew out of the Agua Prieta movement of May 1920, and continued throughout his own administration. As President, Obregón gave intensive attention to military affairs and his military reforms were the most significant achievement of his broadly based effort to consolidate the Mexican Revolution.

Point Of Departure

Mussorgsky's Sunless cycle is aesthetically and stylistically an anomalous member of his oeuvre. Its notably effaced, pared-down, and withdrawn qualities present challenges to critical interpretation. Its uniqueness, however, renders it a crucial work for furnishing the fullest possible picture of Mussorgsky as a creative artist. The author of its texts, Golenishchev-Kutuzov (whose relationship with Mussorgsky at the time of its writing possibly extended beyond the platonic) has been identified by recent scholarship as an essential "eye-witness" for those to whom Stasov's populist characterization of the composer does not ring entirely true. Golenishchev-Kutuzov believed that in Sunless Mussorgsky first revealed his authentic artistic self. According to Golenishchev-Kutuvoz, Mussorgsky regarded his signal achievement in Sunless to have been the eradication of all elements other than "feeling." In other words, he had thrown off the stylistic shackles imposed by the aesthetics of realism and relied entirely on intuitive harmonic invention as the sole conveyor of a purely subjective, "affective" meaning in the cycle. This hypothesis forms the point of departure for an investigation of select numbers of the cycle. Analysis reveals that the affective aspect is not the only significant element operative. Alongside remnants of the realist style, there is evidence, of varying degrees of subtlety, for a knowing use of symmetrical pitch organization. Mussorgsky not only adapted the usual referential attachments of symmetrically based chromaticism--typically found in Russian operas of the second half of the nineteenth century--he also, through extremely simple but effective means, synthesized the "intuitive" harmonic and "rational" symmetrical elements of the cycle's pitch organization so that the latter emerges seamlessly out of the former. This remarkable synthesis ensures the cycle's uniformity of tone while also allowing for a reading that extends beyond the generally affective to the symbolically more specific. This symbolic level of reading offers several interpretative possibilities, one of which may refer even to the relationship of the poet and the composer. Irrespective of such potentials for interpretation, the most significant achievement in the cycle remains the synthesis of the intuitive/affective and rational/symbolic elements of its organization. Songs 1, 2, 3, and 6 of the cycle are considered in detail.

High Level

Like many midwestern cities in the nineteenth century, Cincinnati, Ohio, was home to large numbers of German immigrant musicians, among them the founders of the Cincinnati Grand Orchestra in 1872. Their model of musician-based organization eventually ran counter to the prestige-building potential of Western art music, which made it attractive to local civic leaders determined to earn respect for their city at a national level. The successful Cincinnati May festivals beginning in 1873 under the artistic leadership of conductor Theodore Thomas brought the city the desired renown. But the musical monumentality needed for large festival performances could not be obtained locally, leaving Cincinnati's players with opportunities to perform at a high level but without a way to define their performance as a significant achievement in the world of high art. Although their orchestra was ultimately unsuccessful, however, these musicians demonstrated an agency that transcends their historical obscurity and helps incorporate aesthetic and practical aspects of institution-building into the social arguments common to discussions of Western art music in the United States.

Abstract This paper reports research on approaches for accessing and controlling product data within the Product Introduction Process (PIP) through the specification, prototyping, and integration of a set of product structures, product viewpoints and their relationships. A significant achievement has been the validation of a collection of computer-based models of product structures that enable the capture of work breakdown, product specification, product functionality, and the physical parts that comprise the product. Furthermore, a number of relationships between these product structures and the business processes that use and create them have been identified. The work presented in this paper demonstrates the importance of representing relationships between product introduction processes and products through the adoption of product structures. The potential for exploiting product structures to improve understanding of relationships between products and processes is illustrated. A case study captures flows of related functional and physical product structures within PIPs across a two-tier supply chain, and discusses the issues involved in supporting such related product and process information.

Self Defence

This chapter examines under what circumstances States may use armed force under customary international law and Arts 2(4) and 51 UN Charter. After noting that the use of armed force is generally prohibited and only limited to self-defence, and then only if the target State is under an armed attack, we show that several States have expanded the notion of armed attack. Besides self-defence, the United Nations Security Council may authorize the use of armed force through a process of collective security. Several examples of collective security are offered, as well as the ICJ’s position on what constitutes an armed attack. In recent years, the range of actors capable of undertaking an armed attack has included terrorists. Moreover, the development of the doctrine of the responsibility to protect is a significant achievement.
