O corpo em sofrimento e a Irlanda dos millenials em “At the Clinic”, de Sally Rooney
Authors: Bolfarine Mariana
Published: December 2023

Sally Rooney é um fenômeno recente na literatura irlandesa, sendo considerada por críticos uma “nova Jane Austen” visto que suas narrativas abordam uma parcela da sociedade, correspondente a sua própria geração, a dos millennials, mas sob uma perspetiva irlandesa do período post-crash, momento de reconstrução econômica e social após o fracasso boom econômico, conhecido por Tigre Celta. Sendo assim, tomando como base o contexto histórico da Irlanda post-crash, neste artigo demonstro que no conto “At the Clinic” (2016), de Sally Rooney, o corpo é representado como local de sofrimento e ao mesmo tempo de superação. Pensando na forma como Dillane, McAreavery e Pine (2016), versam sobre o corpo em sofrimento, investiga-se a maneira pela qual Marianne e Connell, os dois protagonistas de “At the Clinic”, lidam com a (in)expressibilidade da dor, física e emocional. Para isso, a discussão também girará em torno daquilo que Chris Weedon (1987) quer dizer por senso comum e normalidade e se (e como) esses conceitos estão indiretamente presentes na maneira pela qual Connell e Marianne se relacionam em “At the Clinic”. Por fim, concluo que as subjetividades desses personagens principais se constroem mutuamente e que, para Marianne, ao mesmo tempo que ela precisa lidar com a dor física durante a extração de um dente inflamado em um consultório de dentista, ela também acaba lidando com as dores emocionais, causadas por sua família disfuncional e por uma sequência de relacionamentos abusivos. No entanto, quando olhamos de perto para as subjetividades que constituem Connell e Marianne, percebemos que o ponto nevrálgico de “At the Clinic” e Normal People é o fato de que o individual se torna político.
Microstructure evolution and its effect on the impact toughness of the Ti-Al-V-Mo-Zr alloy tube
Authors: Chi Guangfang , Liu Huiqun
Published: December 2023

Titanium alloys are widely used in the petrochemical industry owing to their excellent overall performance. In this study, a high-temperature solution treatment in the two-phase region was proposed, with a slow cooling rate resulting in the successful partial globularization of lamellar α microstructure, achieving an extruded Ti-Al-V-Mo-Zr alloy tube elongation increase of 69% and impact toughness increase of 51%. The kinking of lamellar α microstructure promoted its continuous globularization by increasing misorientation. Consequently, the elongation and impact toughness of Ti-Al-V-Mo-Zr alloy tubes could be greatly improved by tuning the microstructure to a mix of coarse equiaxed and lamellar α microstructures, the improved strength being attributed to the secondary α phase (αs) obtained using the proposed method and aging. The results of this study can be expected to provide guidance for the fabrication of highly ductile titanium-alloy oil-drilling tubes.

The Confessional Component of Russian National Self-Consciousness in the Second Half of the 19th – Beginning of the 20th Centuries (on the Materials of the Middle Urals)
Authors: Alexey Telenkov
Published: December 2023

This study is devoted to the national self-consciousness (identity) of Russians in the second half of the 19th - early 20th centuries through the prism of religious beliefs. The work was carried out based on the materials of the Middle Urals (Perm province). The main purpose of the study is to determine the role of confessional identification in the national selfconsciousness and to characterize the mechanisms of its formation by the religious environment. Unpublished personal archives of Ural local historians and collectors of folklore, archives of the authorities of the Perm province, articles from the mass media of the specified period, published materials and collections of texts of historians, philologists, linguists, speeches of priests and townsfolk recorded by contemporaries were used as sources for such an analysis. The analysis makes it possible to fix the confessional component in the manifestations of national self-consciousness. At the same time, the emphasis in the work is made on the Orthodox component of the official Church. The Old Believer ethnics and religious beliefs of the Russian population of the Urals are not considered in the study as having significant differences from the bulk of the Russian people. The work emphasizes that the most important components of the Russian national self-consciousness of the prerevolutionary era was the correlation of the supreme secular power (the tsar) with the spiritual power (the Orthodox Church), which resulted in the image of the sovereign as an archpastor. An important mechanism in the formation of this kind of views is the activity of priests and the intelligentsia and their patronage by the local and supreme authorities. At the same time, the study noted that the formation of such a national-confessional worldview has its roots in the popular Christian and pre-Christian beliefs and ideas.

Authors: Horbacz Agata , Kručanica Ladislav , Kováčiková Zuzana
Published: December 2023

Introduction: A sufficient level of aerobic endurance, strength and balance is an important precondition for performing almost all activities of daily living with advancing age. Multimodal physical interventions seem to be an effective tool to improve overall fitness for of elderly. However, it is not known to what extent such interventions are effective in healthy and physically active elderly people. Therefore, this study aims to assess the effect of an 8-week multimodal training programme focused on aerobic endurance, strength and dynamic balance in physically active elderly females. Methods: A total of 25 physically active women over 60 years of age completed and 8-week multimodal training programme with two 60-minute sessions a week. Their functional performance before and after the intervention was evaluated with the Chair stand test, Arm curl test, 2-minute step test, Chair sit-and-reach test, Back scratch test and Foot up and go test. A program STATISTICA was used for data analyses (TIBCO Software Inc., 2018; version 13). Results: An 8-week multicomponent training programme resulted in a statistically significant performance in 2-minute step test. Moreover, training resulted in a significant reduction of BMI. Surprisingly, training resulted in the significantly prolonged time in the Foot up and go test. No other significant changes have been observed. The training programme resulted in a statistically significant improvement in the 2-minute step test (p=0.007). Moreover, the BMI index significantly decreased after the programme (p=0.037). Surprisingly, training resulted in the significantly prolonged time in the Foot up and go test (p=0.011). No other significant changes have been observed. Conclusion: The 8-week multimodal training programme seems to be an effective tool for increasing aerobic endurance in physically active elderly women. This training does not contribute to more pronounced improvements of other abilities.
The Person Case Constraint, Person Ordering Constraint and Pronominal Clusters in Polish
Authors: Witkoś Jacek , Łęska-Bayraktar Paulina
Published: December 2023

This contribution deals with preverbal clusters of deficient pronouns in Polish and combines an empirical study with a theoretical description inspired by Stegovec (2020). Polish pronouns are ill disciplined in comparison with their Slavic equivalents: they do not have a fixed position, they need not cluster together or with person-number auxiliaries and their cluster-internal ordering does not seem fixed (Franks and King 2000). These properties lead many authors to propose that their deficiency is limited mainly to phonology and morphology, while their syntactic distribution is typical for Slavic DPs. We examine preverbal pronominal clusters in a controlled setting and conclude that they show strong regularities in internal orders compatible with Person Case Constraint (PCC). We conclude that Polish shows effects of this constraint in a limited set of cases; deficient pronouns form a heterogenous group, with 1st and 2nd person SG displaying typical properties of deficient pronouns, and 3rd person masculine showing mixed properties of deficient and strong pronouns. This divide contributes to the idiosyncrasy of the pronominal system in Polish and shows that the three-way classification of pronouns in Cardinaletti and Starke (1994) is too coarse.

Conceptualizing Place Borders as Narrative: Observations From Berlin-Wedding, a Neighbourhood in Transformation
Authors: Barthel Martin , Scott James W.
Published: December 2023

Place is of central significance to urban planning processes that specifically target community involvement and co-ownership of development decisions. Consequently, the intriguing but often daunting task of understanding how a sense of place emerges, develops, and evolves has been a subject of interdisciplinary study that links the social sciences, humanities, and more recently, cognitive sciences. Since Kevin Lynch’s classic study of urban images and mental maps, borders within cities have either directly or indirectly featured as vital meaning-making elements of place identities. However, despite some remarkable precedents, analysis of political and socio-cultural borders has only begun to link place-making and bordering processes in ways that resonate with urban planning studies. In this article, we will suggest that borders emerge in the embodied creation of social space as a means to interpret the environment and stabilise ways of knowing the wider world. Building on our own previous research on participatory place-making initiatives in Berlin, we will indicate how border stories (i.e., the social communication of neighbourhood distinction, relationality, and transformation) represent vital knowledges of place. These knowledges reflect embodied experiences of place as well as contestations and tensions that characterise place development processes. Perhaps most importantly in terms of planning, the salience of urban borders lies in broadening understanding of how and why places function—or fail to function—as communities.
Use of veno-venous extracorporeal membrane oxygenation in a female patient with severe acute respiratory distress syndrome and peri-intubation cardiac arrest. Clinical observation

Published: December 2023

Acute respiratory distress syndrome (ARDS) is a life-threatening form of respiratory failure which can occur in people of any age. It comprises about 10 % of all admissions in intensive care units. The cornerstone of treatment of severe forms of this disorder is protective mechanical ventilation but in patients with initial hypoxia and/or hypotension tracheal intubation is associated with the risk of significant hemodynamic abnormalities. Mortality from severe forms of ARDS remains high. COVID-19 pandemic led to worldwide wider use of such techniques of respiratory support as high-flow nasal oxygen therapy and non-invasive ventilation, the necessity of which is proposed to be used as one of classifying signs of ARDS in addition to the Berlin criteria. If the respiratory therapy is ineffective, veno-venous extracorporeal membrane oxygenation is used for gaseous exchange and decreasing undesirable effects of high pressure in the respiratory pathways. The success of its application strongly depends on the optimal timing of its initialization. The performance of this technique is associated with a number of complications (hemorrhage, thrombosis, sepsis, etc.). Effective treatment of ARDS requires utilization of a large amount of resources and educated staff.

Published: December 2023

BACKGROUND: Solving the problem of efficient use of the Russian-produced energy-saturated 4K4b wheeled tractors of high (235–350 kW) power, which are the basis for the formation of an innovative fleet of mobile energy facilities in the regions of the Siberian Federal District, in zonal tillage technologies with velocity ranges limited by the requirements of agricultural technology and resource saving, is a relevant task.
AIMS: Determination the conditions for the reasonable configuration of the 4K4b wheeled tractors for operational tillage technologies.
METHODS: The basis for solving the problems to achieve the aim is the conditions and methods of a multi-level system of technological adaptation of wheeled tractors.
RESULTS: Based on the results of simulation and experiment, it was determined that the most reasonable method for adapting tractors to tillage technologies in terms of minimum labor costs and the level of capabilities implementation is the formation of the operating mass of the basic configuration at the nominal mode, corresponding to the optimal values of the specific mass atφкр н*=0.40 andVН2=2.90 m/s which aremуд н1*=58.0 kg/kW for single wheels andmуд н2*=62.4 kg/kW for dual wheels, with adjustable axle distribution. The scientific novelty of the study lies in building the model that helps to establish a reasonable traction range of a tractor of various configurations for operational tillage technologies with an interval of nominal operating velocities of 2.5–3.3 m/s, limited by the conditions of resource saving by the modes of maximum traction efficiency and acceptable slipping.
CONCLUSIONS: The practical value of the study lies in the possibility of using the developed recommendations for the reasonable configuration of tractors in tillage operations.

BACKGROUND: Confirmation of the operability of agricultural tractor transmission units is obtained by machinery manufacturers on the basis of bench tests. The development of technical solutions for test rigs for transmissions and load control systems with an approximation to operational modes is a relevant technical task.
AIMS: Development of technical solutions of test rigs for testing transmissions of tracked tractors and load management systems based on the analysis of operational loading of transmissions.
METHODS: An analysis of the operational loading of the transmissions of the DT and VT series tracked agricultural tractors was performed, based on the results of which the technical solutions for loading devices of test rigs were developed that allow reproducing loading modes with parameters statistically equivalent to the operational loading modes on the tested transmissions.
RESULTS: A technical solution is proposed for a test rig with a hydro-closed power circuit, in which a hydraulic loader with a rotating spool, by lifting and relieving the pressure of the working fluid in the pressure lines, forms a load on the parts of the tested transmission in accordance with the operational loading mode obtained as a result of preliminary analysis. A technical solution for a test rig with eccentric loaders is also proposed, in which a constant level of load on the tested transmission is created by hydraulic loaders acting on the track chains, and variable loads are formed by eccentric mechanisms and disturbances from the track chains rewinding.
CONCLUSIONS: The practical value of the study lies in the possibility of using the proposed technical solutions of test rigs to conduct tests of tracked tractor transmissions with an increase in the degree of reliability of their results due to the approximation of the transmission loading conditions on the test rigs to the operational ones.

Published: December 2023

Combined natural and forced convective heat transfer arise in many transport processes in engineering devices and in nature, which is frequently encountered in industrial and technical processes, including electronic devices cooled by fans, heat exchangers placed in a low-ve-locity environment, and solar receivers exposed to winds. In this study, the effects of design parameters have been experimentally investigated for the air-side thermal performance under combined (natural and forced) convection of the rectangular plate heat sinks, and the values of optimum design parameters were sought. Many ideas for improving cooling methods have been proposed, one of which is the heat sink. In this work, the average Nusselt number (Nu) and thermal resistance of a simple base rectangular plate and five vertical rectangular plate heat sinks with different numbers of fins under natural and combined convection were exper-imentally investigated to obtain the maximum average Nu and minimum thermal resistance for various Reynolds numbers (Re) from 2300 to 40000, Rayleigh numbers (Ra) from 1300000 to 13000000, and Richardson numbers (Ri) from 0.4 to 3. Also, in this experiment, fin spacing (P) was varied from 2.8 mm to 14.6 mm and the dimensionless P/H ratio was varied from 0.1 to 0.49. The flow velocity varied in the range of 2 to 8 m/s under combined convection. Based on the effects of Ri and Re, two empirical equations for natural and also for combined con-vection heat transfer were derived to calculate the average Nu. The average deviation for these two equations is about 7%. The outcomes of this research can be beneficial for engineers who work on electronics cooling systems.

Published: December 2023

One of the most effective ways to save energy for cooling and heating applications is thermal insulation. Because of this, determining the ideal insulation thickness is a popular topic for publications. The purpose of this study is to determine the appropriate insulation thickness needed for a submarine’s external construction while it is cruising in various locations. Since seawater makes up a submarine’s external environment, situations involving five distinct sea-water temperatures from around the globe have been studied. There are five of them: the Med-iterranean, Marmara, Aegean, Black Sea, and Sakhalin, which is in the North Pacific Ocean and has the coldest seawater on earth. By using the idea of degree-days, the annual cooling and heating needs of submarines in various regions have been computed. Based on life cycle cost analysis, optimization has been accomplished. In the beginning, the results of a study published in the literature supported the calculation methods utilized. The use of insulation materials such as rock wool, glass wool, polyurethane, expanded polystyrene, fiberglass, and foam glass, as well as fuel oil to run the generator, has been taken into account in a number of calculations, including the best insulation thickness, annual savings value, annual energy cost, and payback period. The findings indicate that depending on seawater temperatures and in-sulation materials, the ideal insulation thicknesses range between 2 and 12 cm, energy savings between 8.5% and 90%, and payback periods between 1.1 and 10 years.

The present study investigates the effects of using a magnetic field on the flow field and heat transfer of ferromagnetic Fe3O4/H2O nanofluid considering two-phase model for nanofluid in heat exchanger equipped with helical ribs. Three methods are employed to enhance the thermal efficiency of heat exchanger, as employing of corrugations, utilizing nanofluid as heat transfer fluid, and employing the magnetic field. The performance evaluation criteria index (PEC) is employed to analyze the thermal-hydraulic characteristics of the heat exchanger. The main aim is to achieve an optimum model with the highest performance evaluation criteria value. Usaging of corrugated heat exchanger or nanofluid can increase the average Nusselt number and friction factor in the tube sharply. Also, it is understood that the presence of a magnetic field has a significant effect on the heat transfer enhancement inside the heat ex-changer. The model with magnetic field of 600 G has the highest Nusselt number ratio among all studied models, which is followed with 400 G, 200 G, and 0 magnetic fields, respectively. Furthermore the effects of different corrugation heights, widths, and pitches have been stud-ied. Finally, usage of the novel corrugated heat exchanger with 14 mm corrugation heights, 9 mm rib width, and 12.5 mm blade pitches filled with nanofluid, and under a magnetic field of 600 G it suggested as the most efficient configuration. Also, at the Reynolds number of 4,000, the highest performance evaluation criteria values are achieved.

The purpose of this study is to present a novel technique for the closed reduction of a divergent Lisfranc fracture-dislocation. Successful closed reduction of this injury limits the morbidity associated with soft tissue compromise that may otherwise delay definitive surgical fixation.

A combination of weighted axial traction/counter-traction with a two-stage manipulation of the medial/middle and middle/lateral columns of the mid- and forefoot was performed. A Kling was affixed to the hallux and second ray within closed loops, then mounted to an intravenous pole. Weight was then applied to the distal tibia. Axial traction-counter traction and manual plantar translation with medial to lateral compression were then combined until successful reduction of the first and second metatarsal was achieved. The third, fourth and fifth metatarsals were hyper-dorsiflexed and abducted with subsequent inline manual traction and lateral to medial compression over the base of the metatarsals. This was followed by plantarflexion and adduction to complete the reduction maneuver.

: A combination of weighted axial traction/counter-traction with two-stage manipulation of the medial/middle and middle/lateral columns of the mid- and forefoot was performed to successfully reduce a divergent Lisfranc fracture-dislocation. Successful closed reduction avoided the need for acute open reduction and mitigated the risk of soft tissue compromise, neurovascular complication, and compartment syndrome.

This novel technique for reduction permitted percutaneous internal fixation due to the satisfactory alignment obtained from the closed reduction maneuver. Early closed reduction obviates the need for acute open reduction and limits soft tissue morbidity. This permits orthopaedic surgeons to non-urgently manage Lisfranc fracture-dislocations with definitive surgical fixation that is amenable to either percutaneous techniques or open reduction and internal fixation.

The aim of the study is to study women at risk of PIH (Primi & Multi) by Colour Doppler velocimetry of uterine arteries. Pregnant women attending the antenatal clinics, screened for possible participation in the present study after explaining the nature of the study. A patient was diagnosed to have PIH if there was a rise in systolic pressure of at least 30 mmHg or a diastolic of at least 15 mmHg over the previously known blood pressure or an absolute rise in the blood pressure of at least 140/90 mmHg was taken to diagnose women as a case of PIH.

Out of the 100 cases, maximum 35 cases (35%) were low risk primigravidae, followed by cases with history of PIH (15%), obesity (14%), Anemia (10%),Essential hypertension (7%), IUGR (7%),Which constitute 53%. Rest of the cases was family history of hypertension (6%), oligohydromnios (5%) and Twin (1%).Maximum cases i.e. 40% were illiterate, 28% cases were educated up to primary school and only 20% were educated up to middle school and above. Total 60% cases were literate. 77.2% babies were alive, Abortion were 5.3% and 16.76% cases were with poor perinatal outcome. Study shows that 22% cases showed abnormal waveform in colour Doppler, out of which 90.90% developed PIH, while 78% cases were with normal waveform out of which only 10.25% developed PIH later. For prediction of IUGR out of 22% of abnormal waveform 86.36 developed IUGR and out of 78% of normal waveform 20.51% developed IUGR.

We conclude that a women with high risk factor (nulliparity and others) having abnormal uterine artery waveforms between 16-28 weeks of gestation (presence of diastolic notch with/without high resistance) are at higher risk of development of PIH (90.90%) and IUGR (95%). An important aspect is the high negative predictive value for PIH (89.74%) and IUGR (78.66%) which helps to detect those patient who will not develop PIH and IUGR early positive prediction enables, one to take preventive measures early thus improving both maternal and perinatal prognosis.
