The subject of the research is the operation process of the rotor of a tilling and separating machine which changes the structure and solidity of the cultivated soil layer according to the agricultural requirements. The author considers the design of the blade of the rotor of a tilling and separating machine. The research object is the blade of the rotor whose form allows it to rotate with a minimum expenditure of energy. The topicality of the research is determined by the fact that the theoretically justified design of the blade of the rotor of a tilling and separating machine will help improve the methods of secondary tillage aimed at the improvement of its agrotechnical characteristics with a minimum expenditure of energy. To define the value of a relative speed of a soil element movement along the blade, the author derives an equation using the method described in P.M. Vasilenko’s theory of soil particles movement along rough surfaces, but the author considers soil particles movement along the blade. The article is based on theoretical research using mechanical and mathematical modeling of working tools interaction with soil. The initial data was collected via the analysis of literary sources. The author substantiates the design of the blade of the rotor of a tilling and separating machine which guarantees its rotation with a minimum expenditure of energy owing to the lesser dispersion of soil particles and the prevention of their building-up on the separating grill. The research results can be used by constructors and specialists developing tillage tools.

The Subject

The anthology “Tazkirat-ush-shuara” of Mutribi Samarkandi is one of the most important literary sources of the 16th century, which was written in Moweraunnahr. In general, this work contains information about poets who were either contemporaries of Samarkandi or related to poetry. The value of this anthology as a literary source, although it has not been been entirely studied by researchers,is in that it represents information about the lives, personalities and works of the poets, which is relevant to the study of poetry and the overall literary situation of that period, and which is the subject of separate and in-depth studies.

The Subject

The review considers A. Rudalyov’s book 4 Shots [ 4 vystrela ], devoted to the ‘new realism’, a trend in 2000s Russian literature, and more specifically, works of four ‘new realists’: Z. Prilepin, R. Senchin, S. Shargunov, and G. Sadulaev. The reviewer criticizes the author for an incomplete and biased presentation of ‘new realism’, which had been a focus of intense discussions among literary critics and scholars for over a decade. The same flaw blights the descriptions of the four chapters’ respective protagonists: Prilepin, Senchin, Shargunov, and Sadulaev. Rudalyov ended up writing a panegyric, albeit with very sparse language, mainly by repetition of flattering epithets from the press. He failed, however, to address the discussion of the ‘new realism’ by critics or supply a review of literary theoretical research on the subject. Therefore, the reviewer finds the book lacking in any historical-literary and philological value.

Abstract The problem of audientia episcopalis in late antiquity has been the subject of extensive research in the past. Previous studies have usually focussed on the legal doctrine, as well as the picture of bishop courts in the light of the literary sources. In contrast, the question of how audientia episcopalis functioned in the legal practice as shown by papyri has caused scholars much difficulty, due to the limited material available as well as the obscure nature of the institution. One could therefore ask: how is it possible that such allegedly common practice of dispute resolution by the bishops—as literary sources make us believe—is so elusive in the papyri? How to explain the simultaneous increase for that period of the papyrological attestations regarding arbitration/mediation carried out by the clergy of lower rank? Could we be dealing with some sort of audientia sacerdotalis functioning in the legal practice? How widespread was in fact the audientia episcopalis, and was this institution homogeneous or rather heterogeneous in nature? The paper presents the attempt to answer these questions by confronting the imperial law with the evidence of legal practice.

Abstract This paper presents the results of a review on variability of key pavement design input variables (asphalt modulus and thickness, subgrade modulus) and assesses effects on pavement performance (fatigue and deformation life). Variability is described by statistical terms such as mean and standard deviation and by its probability density distribution. The subject of reliability in pavement design has pushed many highway organisations around the world to review their design methodologies, mainly empirical, to move towards mechanistic-empirical analysis and design which provide the tools for the designer to evaluate the effect of variations in materials on pavement performance. This research has reinforced this need for understanding how the variability of design parameters affects the pavement performance. This study has only considered flexible pavements. The sites considered for the analysis, all in the UK (including Northern Ireland), were mainly motorways or major trunk roads. Pavement survey data analysed were for Lane 1, the most heavily trafficked lane. Sections 1km long were considered wherever possible. Statistical characterisation of the variation of layer thickness, asphalt stiffness and subgrade stiffness is addressed. A sensitivity analysis is then carried out to assess which parameter(s) have the greater influence on the pavement life. The research shows that, combining the effect of all the parameters considered, the maximum range of 15th and 85th percentiles (as percentages of the mean) was found to be 64% to 558% for the fatigue life and 94% to 808% for the deformation life.

Considerable Discussion

The problem of the duration of the first Roman occupation of Scotland is an interesting and important one, and it has been the subject of considerable discussion since the excavation of Newstead added the evidence of archaeology to that of the scanty literary sources. There can be no doubt that, by the time that Hadrian's Wall was planned, Agricola's conquests north of Cheviot had been relinquished by the Romans, but it is not definitely known at what date after his recall, late in the year A.D. 84, the withdrawal took place. There are four emperors under whom the change of frontier policy thus effected may have occurred—Domitian, Nerva, Trajan and Hadrian. The latter's evacuation of most of Trajan's Eastern acquisitions seemed, at one time, to qualify him as the author of a similar limitation of the Empire's extent in Britain.

Purpose : to provide theoretical analysis of the notion of „assertiveness” and rationale of approaches to the development of future doctors’ assertiveness by means of combat sports (Sambo and Judo). Material : analysis of regulatory documents, literary sources. Results : the author has analysed the essence of the notion of assertiveness, and ideas about the relevance of the quality in doctors’ professional activity. The notion of assertiveness has been defined as the subject quality of an individual integrating initiative and willingness to take risks in difficult situations, self-confidence and positive attitude towards others, the ability to freely make decisions and be responsible for their consequences, persistence in protecting one’s own rights and achieve life goals. It has been shown that the key component of assertiveness manifestations are technologies of subject-subject interaction, that provide mutual correctness and effectiveness of acceptable relations. Means of the combat sports have been viewed as instruments of the development of future doctors’ personal qualities. The potentialities of assertiveness formation by means of the combat sports have been defined. Conclusions : the introduction of the combat sports elements in the professionally applied training of medical university students is an important issue of nowadays, which needs theoretical substantiation and methodical support.

Grazing Intensities

The distribution of soil particle sizes is closely related to soil health condition. In this study, grasslands under different grazing intensities and different cultivation ages grasslands were selected to evaluate the dynamics of soil particle size redistribution in different soil layers. When the grazing intensity increased, the percentage of 2000~150-μm soil particles in the 0–10-cm soil layer decreased; 150~53-μm soil particles remained relatively stable among the grazing intensities—approximately 28.52%~35.39%. However, the percentage of less than 53-μm soil particles increased. In cultivated grasslands, the larger sizes (>53 μm) of soil particles increased and the smaller sizes (<53 μm) decreased significantly (p < 0.05) in the 0–10 cm-soil layer with increasing cultivation ages. The increase in small soil particles (<53 μm) in topsoil associated with grazing intensity increased the potential risk of further degradation by wind erosion. The increase in big soil particles (>53 μm) in topsoil associated with cultivation ages decreased the soil capacity of holding water and nutrient. Therefore, to maintain the sustainability of grassland uses, grazing grasslands need to avoid heavy grazing, and cultivated grasslands need to change current cultivation practices.

Crucial Part

By praising rulers, whose magnificence formed a crucial part of the world order, Pierre de Ronsard and his French colleagues in the second half of the sixteenth century often depicted the world not as it was but as it ought to be. This idea informs Margaret McGowan's book on ideal forms in the age of Ronsard, in which she explores the ways poets and painters extolled the virtues and the theatrical magnificence of perfect princes following the Horatian dictum ut pictura poesis: as is painting so is poetry. McGowan demonstrates the virtuosity of the painters and poets of the sixteenth century in shaping their hymns of praise from the subject matter and ideals of ancient Greece and Rome by following Horace's advice to regard paintings as mute poems and poems as speaking pictures. McGowan shows how artists and intellectuals pursued their goals by creating four kinds of ideal form: iconic forms, sacred images derived from classical literary sources offering princes some guarantee of immortality; triumphal forms that evoke the heroic imperial past; ideal forms of beauty to be found in contemplating the beloved; and dancing forms that mirror rituals of celebration. McGowan claims that such ideal forms were intended to enlighten the ruler himself as much as they celebrated his grandeur in the eyes of others.
