The problems of lexicography of new words that appeared in the Russian language in the 21 st century are considered based on the materials of the upcoming thematic Explanatory Dictionary of Unity and Enmity in the Russian Language of 2000–2020. The author of the article is one of the dictionary compilers. It is stated that the difficulties of describing new borrowed lexical units, that are at the stage of usage, are associated with the establishment of their lexical, grammatical and stylistic characteristics. Criteria for their determination are proposed. The principles of choosing the variant of heading word spelling in a dictionary entry are argued. Based on the methods of definitional, linguoculturological and content analysis using textual material extracted from mass media resources, a methodology for compiling a dictionary entry has been developed, which makes it possible to give a detailed description of the lexical, grammatical, stylistic, paradigmatic and pragmatic characteristics of current borrowings. As a result of this technique application, a dictionary entry of Brexit neologism is presented, reflecting the unstable position of this lexeme in the Russian language system, the status of which fluctuates between a proper name and an appellative. The material and methodology for its systematization can be considered when compiling explanatory dictionaries of new words in the Russian language.

The Biblical heritage: The body as a conflict zone In the article we discuss the ambiguous view of the body in Christian tradition, focusing on the biblical texts and St. Augustine’s Confessions. We suggest that there is a tension in the view of humans in these texts, which by time evolves into a two- or three-part division of man into spirit, soul, and body. As a result, the body or ‘flesh’ has often been regarded as a constraint or burden that prevents people from living the life they were meant to live. We argue, however, that the view of the body in the Bible and in Christian tradition is not unequivocal. The body can appear as a place for temptation and suffering, but it is also God’s creation, the place where the earthly and the divine meet. This results in a fragile and unstable position for the body, which also applies to the two other bodies we discuss in the article: the biblical texts and the Christian church. We also suggest that the conflict depicted in the texts is not primarily between the spiritual and the material. The conflict is rather ethical, social, and eschatological. People are thus supposed to respond to God’s acts by forming a new way of living their life in the body.

The current stage of reforming and develop-ing market structures in the domestic econ-omy requires a more detailed study of scien-tific, theoretical and conceptual provisions that would take into account the peculiarities and specifics of individual industries. The unstable position of strategically important industries is mainly due to a number of com-plex economic and social reasons that re-quire detailed study and the development of effective mechanisms for solving the existing problems. The article discusses the most generalized aspects of the formation of the organizational and economic mechanism of sustainable development of fish farms, tak-ing into account the factors of production potential.

Analysis of a pulse voltage regulator from the point of view of transition to an unstable position and possible bifurcation states. Calculation of the stability condition when changing the parameters of the system. Obtaining the pulse voltage regulator stability surface. This voltage stabilizer can have the basic intrinsic parameters of the system, such as, for example, the load resistance, the value of which can change over time according to unknown laws. In the course of the work, the stability limits for static and dynamic bifurcations were obtained with respect to many parameters of the system, including with respect to the value of the load conductivity. To obtain numerical results, a system with the following main parameters was used: U = 4,1 V, d0 = 0,4, C = 600 F, L = 2 mH, f1 = 0,8 Ohm, G = 0,5 V1, RL = 2 Ohm.

ABSTRACT Spectroscopic observations of AH Herculis during a deep quiescent state are put forward. We found the object in a rare long minima, allowing us to derive accurately the semi-amplitudes: $K_1 =121 \pm \, 4$ km s−1 and K2 = 152 ± 2 km s−1 and its mass functions MWsin 3i = 0.30 ± 0.01 M⊙ and MRsin 3i = 0.24 ± 0.02 M⊙, while its binary separation is given by asin i = 1.39 ± 0.02 R⊙. The orbital period Porb =  0.25812 ± 0.00032 d was found from a power spectrum analysis of the radial velocities of the secondary star. These values are consistent with those determined by Horne, Wade & Szkody. Our observations indicate that K5 is the most likely spectral type of the secondary. We discuss why we favour the assumption that the donor in AH Her is a slightly evolved star, in which case we find that the best solution for the inclination yields i = 48° ± 2°. None the less, should the donor be a ZAMS star, we obtain that the inclination is between i = 43° and i = 44°. We also present Doppler tomography of H α and H β, and found that the emission in both lines is concentrated in a large asymmetric region at low velocities, but at an opposite position to the secondary star, outside the tidal radius and therefore at an unstable position. We also analyse the H α and H β line profiles, which show a single broad peak and compare it with the previous quiescent state study that shows a double-peaked profile, providing evidence for its transient nature.

In this paper, a two-link manipulator system stability performance is designed and analyzed using Optimal control technique. The manipulator system is highly nonlinear and unstable. The system is modelled using Lagrangian equation and linearized in upward unstable position. The closed loop system is designed using optimal sliding mode controller. The system is compared with a known PID controller with an impulse applied and disturbance torques and a promising results has been obtained.

The Woven EndoBridge Device (WEB) is efficient and safe in the treatment of wide-neck bifurcation intracranial aneurysms. A crucial step in operative planning is establishing the appropriate dimension of the device, and there are limitations to the therapeutic solutions provided by WEBs. We describe a case of a right middle cerebral artery bifurcation wide-neck aneurysm treated with WEB. After the initial deployment of a WEB proven oversized, we substituted it with a smaller one that presented immediate post-detachment intra-aneurysmal tilt probably resulting from undersizing. The 24-h angiographic control identified a partial displacement of the device in the superior middle cerebral artery branch. We describe rescue techniques with review of the literature and our treatment strategy, including effort to reposition the device followed by stent deployment. The treatment was electively completed by the coil-through technique. The post-detachment WEB tilt should be considered an unstable position and treated either by removal of the device or with adjunctive implants. Each WEB size adapts to a range of aneurysmal height and width. This range is not always the same for each specific WEB dimension, based on the table provided by the manufacturer. This eventually predisposes to a different behavior of different WEB sizes regarding the modification of the device’s height in relation to the modification of the diameter after deployment.


In this concept, analyze two processes model with certain tuning conditions. Design process with nonlinear conditions, disturbance and unstable position along with mutually interaction. Most of the processes are dynamic only w.r.t manipulated variable, disturbances and other unexpected conditions. Two models are resembled as interactive and mutual controlled process through sensors. Compare both processes with and without nonlinearity along with disturbance with tuning condition upto reach set point. Estimate prediction horizon, control horizon, weighted input, weighted rate of input, weighted output and desire trajectory are imposed for both processes by nonlinear predictive control. The main intense to regulate pressure and get desire level with impact of disturbances as temperature, added impurities etc… In this work, can be extended interaction of process with NMPC by adding more complexity and stabilize with certain tuning methods. NMPC is advance method to predictive input as well as output with respected sample time based on prediction horizon and control horizon on receding horizon of axis.

In The Dunciad in Four Books Pope aimed his satire at the literary and intellectual world of eighteenth-century London, and especially its scholars, editors, and publishers. But Pope’s satire is also directed against contemporary developments in religion and theology. This chapter argues that Pope attacks fashionable ideas about the nature of God and the material world in The Dunciad as a way to explore his own ideas about the complex, often-paradoxical nature of imaginative fiction. Through allusions to the religious debates of his day, Pope encourages readers to link theological anxieties about the individual’s relationship to unseen truth with conceptual uncertainties about the power of literary fictions; to see that fiction, like religion, mediated between unknowable human interiority and the visible external world, and thus occupied an ambiguous, unstable position in relation to empirical phenomena.
