The features of finite-element modeling of a structural element of flexible woven composites

AbstractThe features of finite-element modeling of both an element itself and its behavior under uniaxial tension have been demonstrated with a structural element of flexible woven composites. The main components of the material, such as reinforcing fabric and material's matrix were examined in modeling. The reinforcing fabric is a plain weave. These yarns were taken as an elastic material. The matrix of the material was considered to be a soft polymer with the possible occurrence of irreversible elastic-plastic deformations. Moreover, the possible occurrence of damages in the structure of the material under high loads was taken into account in modeling. The fields of stresses and strains were built; the zones of the material's internal damages under uniaxial tension were demonstrated. The risk zones of weave were revealed

Аналитическое будущее время в языке русских цыган как калька с восточнославянских языков

This paper discusses the development of the analytic future in Russian Romani. In this Romani dialect, an analytic future tense can be expressed by means of the two auxiliary verbs avéla ‘to come’ and léla ‘to take.’ This article argues that the development of this analytic future was induced by contact with Eastern Slavic languages. In Romani, the verb avéla also functions as the future form of the copula, thus its use as an auxiliary to derive future tense is a calque from the Slavic construction with the verb budu ‘I will.’ In the article it is argued that the use of the verb léla as an auxiliary is a “fossilized” calque from Old Russian, in which the verb jati ‘to take’ was, up to the 16th century, one of the main ways to derive the future tense. It is also shown that there is no clear semantic distinction between the two constructions, and that preference is given to one or the other depending on the areal variety or even idiolect. Finally, Soviet Romani literature offers interesting cases that demonstrate when the verb léla begins to function as a future tense copula.В статье обсуждается развитие аналитического будущего времени в языке русских цыган. В этом диалекте цыганского языка существует особый способ для выражения будущего времени с помощью вспомогательных глаголов авэ́ла ‘приходить’ и лэ́ла ‘брать, взять’. Развитие этих аналитических конструкций связывается с влиянием восточнославянских языков. В цыганском языке глагол авэ́ла также используется как будущее время глагола-связки ‘быть’, поэтому его употребление в качестве вспомогательного глагола для образования будущего можно трактовать как кальку со славянских конструкций с глаголом буду. В статье доказывается, что использование вспомогательного глагола лэ́ла является “окаменевшей” калькой со старорусского, в котором глагол яти вплоть до XVI в. оставался одним из главных способов для образования будущего времени. Также показывается, что нет четкого семантического различия между этими двумя конструкциями, предпочтение отдаётся одной из них в зависимости от говора или идиолекта. Наконец, советская литература на цыганском языке содержит интересные примеры, иллюстрирующие то, как глагол лэ́ла начинает функционировать как будущее время глагола-связки

Our experience with Russian voice prostheses long used in patents after laryngectomy with tracheoesophageal shunting and endoprosthesis replacement

Despite broad current diagnostic capabilities, most (60–70 %) patients with larynx cancer seek medical advice only when they have stages III and IV. Until the present time, laryngectomy has remained the most common treatment option for cancer of the larynx and laryngopharynx. Tracheoesophageal shunting with endoprosthesis replacement is one of the most important surgical vocal rehabilitation techniques after laryngectomy. According to different authors» data, the mean lifetime of voice prostheses is 6–12 months. The long-term use of voice prostheses in patients after laryngectomy with tracheoesophageal shunting with endoprosthesis replacement was the object of our investigation.Patient G., aged 34 years was admitted to the Department of Head and Neck Tumors, Oncology Clinical Dispensary (OCD) One, Moscow Healthcare Department, with a diagnosis of larynx cancer spreading to lymph nodes (LN) (T3N1M0) in the left neck on September 16, 2010. Surgery involving laryngectomy with tracheoesophageal shunting and implantation of a Russian voice prosthesis, as well as radical fascial excision of LN and fat in the neck on the left side were performed on September 21, 2010. During the 4-year use of the voice prosthesis, his voice was sonorous and good. The voice prosthesis was removed in November 2014. Antifungal therapy was used; a new voice prosthesis was implanted. His speech was fluent and his voice was sonorous and good.Patient M., aged 54 years was admitted to the Department of Head and Neck Tumors, OCD One, Moscow Healthcare Department, with a clinical diagnosis of laryngopharynx cancer (T4N1M0) and an aftereffect of gamma-therapy with a summary focal dose of 42 Gy on November 18, 2003. Surgery involving laryngectomy with laryngopharyngeal resection, tracheoesophageal shunting, and endoprosthesis replacement with implantation of a Russian voice prosthesis, as well as radical fascial excision of LN and fat in the neck on the right side were performed on November 25, 2003. The voce prosthesis was removed in December 2014. Antifungal therapy was performed. A new Russian prosthesis was implanted in the tracheoesophageal shunt. His voice was sonorous and good

Micro-Structured Ferromagnetic Tubes for Spin Wave Excitation

Micron scale ferromagnetic tubes placed on the ends of ferromagnetic CoTaZr spin waveguides are explored in order to enhance the excitation of Backward Volume Magnetostatic Spin Waves. The tubes produce a closed magnetic circuit about the signal line of the coplanar waveguide and are, at the same time, magnetically contiguous with the spin waveguide. This results in a 10 fold increase in spin wave amplitude. However, the tube geometry distorts the magnetic field near the spin waveguide and relatively high biasing magnetic fields are required to establish well defined spin waves. Only the lowest (uniform) spin wave mode is excited.Comment: 3 pages, 3 figure

Dispersion and spin wave "tunneling" in nano-structured magnetostatic spin waveguides

Magnetostatic spin wave dispersion and loss are measured in micron scale spin wave-guides in ferromagnetic, metallic CoTaZr. Results are in good agreement with model calculations of spin wave dispersion. The measured attenuation lengths, of the order of 3um, are several of orders of magnitude shorter than that predicted from eddy currents in these thin wires. Spin waves effectively "tunnel" through air gaps, produced by focused ion beam etching, as large as 1.5 um.Comment: 3 pages, 5 figure

CLINICAL VALUE OF MULTISLICE SPIRAL X-RAY COMPUTED TOMOGRAPHY WHEN PLANNING THE TREATMENT OF PATIENTS WITH LARYNGEAL CANCER

Cancers remain a priority for modern society. According to the WHO estimates, global cancer morbidity  and mortality rates will triple in the period 1999 to 2030: from 10 to 30 million new cases and from 6 to 17 million deaths recorded every year, which will exceed deaths from cardiovascular diseases and injuries. The efficiency of treatment in cancer patients and their prediction are determined by timely disease diagnosis, tumor extent estimation, and adequate therapeutic measures. So search for ways to cardinally improve the early recognition of cancer is one of the major tasks in the study of the problems of cancer patients, those with throat cancer in particular
