Cables and wire ropes are known to both elongate and reduce diametrically during their lifetime. The relationship between cable elongation and cable life has been observed for many years and includes three distinct stages. The first, the constructional stretch stage, occurs early in the cable’s use and is mostly the result of the core compressing and the cable elements fitting closely together. The second stage of the cable’s life is referred to as the normal life stretch stage and is a much more gradual occurrence in which wear is the most dominant mechanism. The third stage includes a rapid elongation and indicates impending failure. The current study offers a simplified explanation on the effect of wear in cables. This work utilizes the recently developed theory for wire ropes and cables in which the cable is considered to be a collection of thin helical wires and the equations of equilibrium for bending and twisting of thin rods are applied. A simple cable cross section is considered and the effects of wear on cable stiffness, diameter reduction and individual wire strains are evaluated. It is determined that cable stiffness can actually increase for small amounts of wire wear due to the disparity between the changes in the geometric and elastic stiffness components with wear.

In the experiment carried out on three groups of dry cows 6 goals in each, the influence of introducing of Trutenat to them on the content of Zincum, Cuprum and Mangan in carunculs of the placenta maternal part and the course of calving researched. The drug is not introduced to cows of control groups, the first group with course of physiological calving and the third at detention of the placenta, and the second group was injected three times at intervals of 7 days, were injected subcutaneously Trutenat in a dose of 7 ml/100 kg of body weight. At all cows throughout 30–45 minutes after birth of the calf we exterpited 2 caruncles, in which we determined the mineral content. The level fluctuation of the test substances in carunculs depending on the current third stage of calving set. The concentration of Zincum in carunculs of cows during the detention of the placenta is higher than in cows of the second (experimental) and the first (control) groups, and Cuprum is lower compared to the first and the second control group, Mangan – below relative to both control groups.The physiological calving courses with different concentration of Zn (61.45 ± 1.34 μmol/l), Cu (0.73 ± 0.1 μmol/l) and Mn (213.3 ± 2.7 μmol/l) in carunculs of the placenta maternal part. The second stage of calving of all cows was within the physiological framework without rendering assistance, ranged from 57 to 85 minutes and amounted 67.5 minutes to an average.Depending on the duration of the third stage of calving we determined the relationship of the studied mineral substances between their levels in blood and maternal parts of the placenta. On the pathology of the third stage of calving in cows blood in the first stage the level of Zinc amounted to 134.15 µg%, Cuprum –90.8 µg %, Mangan –to 3.7 µg%. Separation of the placenta lasted longer for 20–22 hours.

Critics have argued that Elizabeth Gaskell's first novel, Mary Barton (1848), is split by a conflict between the modes of realism and romance. But the conflict does not render the novel incoherent, because Gaskell surpasses both modes through a utopian narrative that breaks with the conflict of form and gives coherence to the whole novel. Gaskell not only depicts what Thomas Carlyle called the ‘Condition of England’ in her work but also develops, through three stages, the utopia that will redeem this condition. The first stage is romantic nostalgia, a backward glance at Eden from the countryside surrounding Manchester. The second stage occurs in Manchester, as Gaskell mixes romance with a realistic mode, tracing a utopian drive toward death. The third stage is the utopian break with romantic and realistic accounts of the Condition of England and with the inadequate preceding conceptions of utopia. This third stage transforms narrative modes and figures a new mode of production.

Abstract This practice report describes how Chinese meditators understand the “four foundations of mindfulness” (satipaṭṭhāna, sinianzhu 四念住) as a remedy for both mental and physical suffering. In the tradition of Theravāda Buddhism, satipaṭṭhāna is particularly recognized as the core knowledge for understanding the relationship between mind and body, and the core practice leading to liberation from suffering. Based on interviews with Chinese meditation practitioners, this study develops three main themes concerning how they have alleviated afflictions through the practice of satipaṭṭhāna. The first theme highlights how practitioners learn to overcome meditation difficulties with “right attitude.” The second theme is about practicing awareness with “six sense doors” open in order to facilitate the balance of the “five faculties.” The third theme explores how practitioners cultivate daily life practice through an understanding of the nature of mind and body as impermanent and as not-self. This paper details how these themes and embodied practices of satipaṭṭhāna constitute ways of self-healing for urban educated Buddhists in the contemporary Chinese context.

AbstractThis article investigates an effective method with which to reconstruct the tragus and external auditory meatus for microtia reconstruction. The external ear was reconstructed using a delayed postauricular skin flap in patients with congenital microtia. After the first stage of delaying the postauricular skin flap and the second stage of otoplasty with ear framework fabricated from autogenous rib cartilage draping with the delayed skin flap, the third stage involved tragus and external auditory meatus canaloplasty. After designing the remnant auricle flap, the lower part was trimmed and the tragus was reconstructed. The upper part was trimmed into a thin skin flap, which was rotated and used to cover the hollowed wound posterosuperior to the tragus so as to mimic the external auditory meatus. If remnant wounds were present, skin grafting was conducted. In total, 121 patients with congenital microtia were treated from March 2010 to March 2016. The reconstructed tragus and external auditory meatus were well formed, and all wounds healed well. No severe complications such as flap necrosis occurred. Six months postoperatively, the morphology of the reconstructed tragus and external auditory meatus was good. Overall, the patients and their families were satisfied. The use of remnant auricle to reconstruct the tragus and external auditory meatus is an effective auricular reconstruction technique.

В статье предлагается концепция жизни и творческого роста В.М. Шукшина сквозь призму тезаурусного и кластерного подходов. Объяснительными «персональными моделями» для интерпретации биографического текста писателя являются кластеры Мартина Идена, Гамлета и Степана Разина. Ранее биографы и литературоведы указывали на важность этих персон для Шукшина, но разрозненно. Впервые предпринята попытка свести указанные персональные модели воедино, в целостный сюжет становления писателя в пространстве культуры. На разных этапах эволюции автора доминирует одна из указанных моделей, последовательно сменяя друг друга, но не вытесняя, а «внахлест». Ранний этап творчества, ориентированный на стратегию Мартина Идена, является попыткой «вписаться» в наличный культурный мейнстрим. Выражено это в следовании поэтике соцреализма. Второй этап подспудно начинается с реабилитации отца Шукшина в 1956 года, когда актуализируется «гамлетовский комплекс», проявляющийся в чувстве вины перед отцом, через стратегию утаивания подлинного «я», мотивы чудаковатости. Третий этап связан с личностью реального исторического лица, Степана Разина, и выражается в открытом протесте против власти. Все важные для В.М. Шукшина поведенческие модели объединены мотивом одинокого противостояния враждебному социуму и имеют трагический финал, что обусловило ранний уход писателя и порождение мифов о насильственном характере его смерти. В.М. Шукшин одновременно был фигурой неординарной и типичной, что позволило его биографии стать «персональной моделью» для последующих авторов, выходцев из сельской глубинки. The article proposes the concept of life and creative growth of V.M. Shukshin through the prism of the thesaurus and cluster approach. The explanatory "personal models" for interpreting the biographical text of the writer are clusters of Martin Eden, Hamlet and Stepan Razin. Earlier, biographers and literary critics pointed out the importance of these people for Shukshin, but it was scattered. For the first time, an attempt was made to bring these personal models together into an integral plot of the formation of the writer in the space of culture. At different stages of the writer’s evolution, one of these models dominates, successively replacing each other, but not crowding out, but “overlapping”. The early stage of creativity, focused on Martin Eden’s strategy, is an attempt to “fit in” the current cultural mainstream. This is expressed in following the poetics of socialist realism. The second stage implicitly begins with the rehabilitation of Shukshin’s father in 1956, when the “Hamletian complex” is actualized. It is manifested in a sense of guilt towards his father, the strategy of concealing the true “I”, eccentricities. The third stage is connected with the personality of a real historical person, Stepan Razin, and is expressed in an open protest against the authorities. All important for V.M. Shukshin's behavioral models are united by the motive of a lonely confrontation with a hostile society and have a tragic ending, which led to the early departure of the writer and the generation of myths about the violent nature of his death. V.M. Shukshin was an extraordinary and typical figure at the same time. That allowed his biography to become a “personal model” for subsequent authors who came from the rural outback.

Background: Several risk factors have been identified for postpartum hemorrhage, one of which being the duration of the third stage of labour. This stage refers to the interval between the expulsion of the fetus to the expulsion of the placenta. Some bleeding occurs in this stage due to the separation of the placenta Objective: This study aimed to identify the factors associated with the length of the third stage of labour. Methods: In this cross-sectional study, 300 women hospitalized for vaginal birth were selected via convenience sampling. The study data were collected using a researcher-made questionnaire. Then, the data were analyzed using univariate and multivariate linear regression analyses. Results: The mean (SD) age of the participants was 26.41 (6.26) years. Investigation of the relationship between the study variables and the time of placental separation indicated that a minute increase in the length of membranes rupture caused a 0.003minute decrease in the time of placental separation. However, this time increased by 2.75, 6.68, and 2.86 minutes in the individuals without the history of abortion, those with the history of stillbirth, and those who had not received hyoscine, respectively. The results of multivariate analysis indicated that suffering from preeclampsia or hypertension, history of stillbirth, not receiving hyoscine, and not receiving misoprostol increased the length of the third stage by 4.40, 8.55, 2.38, and 6.04 minutes, respectively. Conclusion: Suffering from preeclampsia and having the history of stillbirth increased and using hyoscine and misoprostol decreased the length of the third stage of labour. However, no significant relationship was found between the length of the third stage of labour and mother’s age, gestational age, parity, mother’s body mass index, mother’s chronic disorders, history of manual placenta removal, length of the first and second stages, membranes rupture, induction, amount of oxytocin after delivery, and infant’s weight and gender.

Most authors considered pleural cavity drainage to be the main method of treatment of acute pleural empyema using minor surgery. Despite the simplicity of drainage of the pleural cavity, the number of complications after this surgical manipulation, according to the reports of some authors, varies from 3 to 8 %. The complications of pleural drainage in the patients with acute nonspecific pleural empyema have been studied and the technique of pleural drainage "blindly" has been introduced, which allows drainage to be located along the chest wall. At the first stage of the four−stage study, the complications of pleural drainage in 38 patients with acute nonspecific pleural empyema were analyzed, at the second stage a device for drainage of the pleural cavity "blindly" was developed to place drainage in parallel to the chest wall, at the third stage patients were tested; on IV −− drainage of the pleural cavity of 34 patients was performed according to the proposed method. The reason for the development of drainage complications in the pleural cavity of patients with acute pleural empyema was the inadequate location of drainage in the pleural cavity, drainage of the pleural cavity was carried out in general hospitals without the use of thoracoscopic equipment. Curved thoracoport with trocar for a blind drainage of the pleural cavity "blindly" was developed and introduced into clinical practice. This technique eliminates the involuntary location of the drainage in the pleural cavity, installing it along the chest wall, and is safe. Complications associated with drainage of the pleural cavity according to the developed method using a curved thoracoport with a trocar, inadequate location of drainage, were not observed in patients. Key words: acute pleural empyema, pleural cavity drainage, curved trocar.
