The Cycle of sixth-century epigrams edited by Agathias Scholasticus is the subject of a recent article by Mr and Mrs A. Cameron (JHS lxxxvi [1966] 6 ff.), who argue cogently that it was published in the early years of Justin II, and not the later years of Justinian, as has hitherto been supposed. Ca. also suggest identifications for many of the poets and imperial officials who figure in the Cycle. They do not, however, exhaust all the identifications that can be made, and some of those suggested by them require amplification or correction. Furthermore, Ca.'s view of the dating of the Cycle leads them, it seems to me, to underestimate its Justinianic character. The following observations are offered without prejudice to the merit of Ca.'s article as a whole.Among the Cyclic poets, only Julian the ex-Prefect of the East stands in close relationship to the political life of the age. His involvement in the Nika insurrection of 532 is attested by historical sources and, as Ca. claim (13), by two epigrams of the Anthology. The latter, however, contain difficulties passed over by Ca. In the first place, of the two epigrams on the cenotaph of Hypatius, only AP vii 591 is certainly from Julian's pen; vii 592 is unattributed in the Palatine MS., a fact which Ca. omit to mention. (It is absent from the Planudean MS.) The state of affairs in P is no accident, vii 591, though eulogising the dead man and alluding openly to the casting of his corpse into the sea, is moderate in tone, and would have caused no more offence to Justinian than Procopius's published account of the affair.

In the presented study, the educational dialogue is understood as a model of subject-oriented interaction, as a kind of idea which specifies the way of thinking about education. By creating the possibilities of self-expression for its participants, this process shapes the orientation towards the subject of all the participants. However, this can take place only if appropriate conditions are provided for the participants and the teachers are aware of their being role models for their learners. The article deals with the basic models of educational cooperation, namely the model of spontaneous actions of students and their adaptation activity – quasi-objective model; the model of teacher planned events and actions – the object model; the model of coordinated activities of teacher and students – the subjective model.The main criteria for defining those models are: the type of student / teacher activity – from natural, due to their own internal reasons, and inspired to the actions that are directed by the teacher only; correlation between the level of activity of students and teacher – there is a close relationship among them, i.e. the more active teacher is, the less space is left for student activities and vice versa; the nature of relationship between teacher and students as between the two partners.It should also be noticed that due to the nature of the subjective educational communication – direct (student-teacher interaction) or indirect (teacher directs student relationship in class) – there is a possibility of effectively influence on the development of the subjective orientation of every student. This is a teacher's personal example given in personal relations that has an impact on the extent to which children develop consciousness.

This paper aims to describe how additive manufacturing can be useful in enhancing a robotic course, allowing students to focus on all aspects of the multidisciplinary components of this subject. A three-year experience of the course of “robotic system design” is presented to support the validity of the use of this technology in teaching. This course is specifically aimed at Master of Science (MSc) Mechanical Engineering students and therefore requires one to view the subject in all its aspects including those which are not conventionally taken into consideration such as mechanical design, prototyping and the final realization.

Courses in mechanical engineering usually introduce the theory of axial-flow turbo-machines in terms of simple velocity triangles representing the bulk flow of ideal compressible fluid through the blade passages. A distinctive practical difference, peculiar to steam turbines (ST), is the presence of liquid-water in the flow field. The steam wetness in such turbines is widely known to be doubly-damaging, leading to both loss of efficiency and to mechanical damage (erosion, etc.) of the machine components. Over recent decades, a whole new field of mechanical engineering science has evolved on the subject of wetness in steam turbines, and general practices have been established within the industry. This article reviews the general effects that are of major importance to the turbine designer/engineer, power plant operator, and especially to researchers in this field.

The spread of the Headwaters Lakes Aspect in a northwesterly direction through Manitoba, has been the subject of previous comment by the senior author. The manifestations of the aspect in this area, have a marked resemblance to the Black Duck Focus, and have been defined as the Manitoba Focus.The factual data upon which this conclusion is based are derived from three controlled excavations in Manitoba. Hecker and Hlady excavated the Lockport site, north of the city of Winnipeg, in August, 1947. Hecker reports the presence of sherds that show a “close relationship” to the Black Duck Focus. During 1947 and 1948 the junior author conducted excavations on the Scott site near Brandon, Manitoba. This site is located on the S.W. Sec. 35, T. 10, R. 20, W. 1, and has yielded a good collection of Manitoba Focus sherds, with an associated artifact complex that closely corresponds to that outlined by Wilford for the Headwaters Lakes Aspect.

The causes of dementia continue to be the subject of huge research efforts, and post-traumatic stress disorder (PTSD) has recently gained attention as a possible contributor. PTSD is considered to be present if the sufferer develops persistent re-experiencing, avoidance and emotional numbing and symptoms of increased arousal not present before the sufferer was exposed to a traumatic incident. PTSD is now classified in DSM-5 as a trauma- and stressor-related disorder, unlike DSM-IV where it was previously categorized as an anxiety disorder, lending it more prominence now as a stress-related condition. However, it remains placed near the anxiety, obsessive compulsive and dissociative disorders in recognition of the close relationship with these other diagnoses. The nosology of PTSD is interesting as the symptoms can vary considerably. Some individuals with PTSD exhibit anxious or fear-based symptoms, while others can experience anhedonic, dysphoric, aggressive or dissociative symptoms (American Psychiatric Association, 2013).

The paper outlines some of the engineering problems which arise in connexion with naval mining, and describes some of the weapons and devices used by Britain and Germany in the war of 1939–45. Although naval mining has a long history, its development is necessarily conducted under conditions of secrecy, and publication of information concerning it is possible only after a major war in which there has been a general disclosure of methods and materials employed by both sides. The popular conception of a mine is a spherical buoyant object which will explode if hit by a ship. The buoyant contact type is, however, only one of many forms now available. A number of these are illustrated here, and the variety may surprise those not familiar with the subject. Methods of laying, general principles of operation, and safety requirements are described, and the mechanical details of design of mineshells, fittings, components for control and firing circuits, and other features are mentioned. Naval mines have reached a state of considerable complexity and many fields of scientific knowledge are now called upon in making them effective weapons.

The purpose of the article is to put forward English monologue production assessment criteria to verify the efficiency of the devised methodology of teaching English for future mechanical engineers. In the course of the research, theoretical, empirical, and statistical methods have been used. Various approaches to identifying the assessment criteria have been thoroughly analyzed. Seven criteria to assess the monologue production skills, five primary and two secondary ones, have been suggested. The allocation of the points by every criterion according to the devised scales have been elucidated. The proposed assessment criteria were used in the methodological experiment that was held at Igor Sikorsky Kyiv National Technical University. The experiment in question aimed to verify the efficiency of the devised methodology of teaching English monologue production to students majoring in mechanical engineering. Three experimental groups, 34 students in total, studying in their final year of Bachelor studies within the Subject Areas of Applied Mechanics and Industrial Engineering, participated in the methodological experiment. The conducted experiment confirmed the efficiency of the methodology proposed.

This research aims to describe the implementation of Movie for Mechanical Engineering students of Politeknik Harapan Bersama Tegal. The method used is class action research using 2 cycles. The subject of this study is class 6C with 26 people. The student's improvement in vocabulary understanding is 60% in the first cycle. However, the results were categorized as failed because only 10 students received a minimum score of 73 or above 73. So the second cycle is implemented. In the second cycle there is an increase in the percentage understanding vocabulary 75% of the average value of 69-86. So it can be concluded that the student's understanding increases using movie.
