Role of Sonography in the Diagnosis and Treatment of de Quervain Tenosynovitis
Authors: Rodrigues Jean
Published: September 2024

De Quervain tenosynovitis is an inflammatory process involving the synovial coverings of the tendons of the thumb, namely the abductor pollicis longus and extensor pollicis brevis. The disease process is a result of impingement of the tendons due to effective narrowing of the potential space between the radial styloid and the overlying extensor retinaculum through which they run. The aim of this study was to determine the role of sonography and the extent of its use in the prognosis and diagnosis of de Quervain tenosynovitis.

This article is based on a review of journal articles with information and findings specific to both the first extensor compartment and de Quervain tenosynovitis. The rationale was to design a checklist based on a comparison between normal and abnormal findings of the first extensor compartment in order to perform a complete and thorough scan with regard to de Quervain tenosynovitis.

Sonography demonstrates distinct changes in echogenicity, thickness, and perfusion of the tendons and their sheaths in cases of de Quervain tenosynovitis. It also helps in identifying variants such as the presence of an intracompartmental septum and accessory tendons commonly associated with the condition.
Intra-Cardiac Mass: A Case Report
Authors: Dultra Hersha May S. , Zielke Sayeh
Published: September 2024

A 50-year-old female patient presented with shortness of breath. She had pulmonary hypertension and a recurrent history of pulmonary emboli and strokes. A large mass was discovered in the right atrium. It was multi-lobulated and mobile, also causing obstruction to flow across the tricuspid valve. Further investigation into this patient's medical history revealed a rare condition which was key to the identification of this mass as a cardiac thrombus. She was diagnosed with anti-phospholipid antibody syndrome (APS), which is an auto-immune disease. In this condition, antibodies formed against blood proteins lead to thrombus formation, which can affect the heart valves, become a source of intra-cardiac thrombus, and cause systemic embolization, leading to stroke, myocardial infarction and pulmonary embolism. This case demonstrates the importance of thorough medical history and context for making the correct diagnosis based on echocardiographic findings.
Supraspinatus Tendon Thickness Parameters for the General Population
Authors: Dima Robert S.
Published: September 2024

Rotator cuff ultrasonography is frequently performed to diagnose and manage shoulder pathology, and an important portion of the investigation is the measurement of muscle tendons, particularly when tear or tendinosis is suspected. The most common tendon to exhibit pathology is the supraspinatus tendon (SST) of the rotator cuff. Although normal measurements of the SST are available in the literature, they tend to vary and are onerous to access. In the effort to provide a single, compiled source of information for the practitioner performing the shoulder ultrasound exam, this study presents a meta-analysis of academic reports on thickness measurements of the normal supraspinatus tendon. Statistical analysis of the data is performed to arrive at a weighted mean for SST thickness in the general population. The 2 SD estimate of the population mean SST thickness is 3.9 mm-7.0 mm. The point estimate for SST thickness is 5.43 ± 0.77 mm, which indicates a high rate of variation. The hypothesis that males may have greater tendon thickness than females cannot be corroborated based on the results of this research, and the results are not consistent with previous studies suggesting a maximum tendon thickness of 6 mm to indicate the presence of tendinopathy.
Crónica de una mujer transgresora: la moda garçonne en Lima, (1919-1930)
Authors: Terreros Roldan Daniella
Published: September 2024

Durante la década de 1920, los múltiples cambios sociales y económicos que vinculan a la mujer al mundo laboral y la participación de la vida pública conducen a una gran transformación del vestuario. Se daba paso al surgimiento de la moda garçonne, y con ella, una propuesta vestimentaria de carácter sencillo y funcional considerada “masculinizada”. En efecto, será una práctica de vestir personificada en una imagen de mujer transgresora. Esta fémina, criticada en su comportamiento y modas, será vista como una usurpadora de los privilegios masculinos; así como también tildada de independiente, superficial y despreocupada por el ámbito doméstico y familiar. A propósito, a partir de los diarios, revistas y fotografías de la época, se pretende ilustrar un contexto donde estas garçonnes limeñas dejaron entrever una “seguridad aventurera” a partir de su lectura de la moda como una forma de expresión social y un espacio de negociación de libertades culturales y roles sociales.
The software for improvement of image quality after enlargement
Authors: Tuzenko O.A. , Volodin S.I.
Published: September 2024

In the paper digital images of various formats were investigated. The different vector image formats have different color rendering capabilities. The main task was to achieve a result of refinement of the random low resolution color raster image without quality and resolution loss. The biggest advantage of using specific vector or compressed raster formats is the ability of scaling without quality loss and comparatively small file size. This eases vector images transfer through networks. In the article a specific algorithm of raster images refinement was investigated, particularly the method of raster images refinement based on combination of interpolation algorithms with and without square root of the color values. The key point of the method is comparison and combination of vertical, horizontal and diagonal interpolation that allows to achieve better precision on color depth calculation. This exact method was never used in commercial of scientific software though there are different variation of combined interpolation methods similar to current one. In this paper two different approaches to image matrix re-calculation during image refinement were tested, in order to research how root squaring the value of color depth would affect the target color value. The result shows that this approach allows to keep more details in shadows and save contours during interpolation though the images lose somewhat of color depth. The experiment shows that this interpolation method with square rooting color values allows to enlarge and refine color images with complex tone curve structure and keep details of the objects in place, though color depth is worsened especially in deepest shades and blacks. On the opposite the method of combined interpolation without root squaring gives significantly better result with color interpolation but loses details in the dark areas of the initial image. The suggested method can be used in a number of different areas

Authors: Hryhorenko V.U. , Ovsianykov V.V.
Published: September 2024

Since 2020, in Ukraine, LLC NVP «UKRTRUBOIZOL» began to operate a technological line for the production of large-diameter pipes (TVD) for main oil and gas pipelines with a hydromechanical expander. From 2023, interstate GOST 20295-85 and GOST 10706-76 ceased to be valid in Ukraine. Formulation of the problem. Ukrainian standards are needed. It is necessary to determine the rational values of the deformations and the effectiveness of the expansion to reduce the residual stresses in the metal of the pipes. Goal. Development of Ukrainian standards for TVD production and determination of the effect of expansion on residual stresses. Method. The method of cutting rings was used. The results. Developed and implemented with the participation of author: DSTU 9219:2023; DSTU 9218:2023 and TU 24.2–05757883–095:2022. Pipes with a diameter of 630 mm, with a wall of 8 mm, made of S335 steel and hot-rolled rolled sheet were studied. The opening between the longitudinal edges of the pipe blank after bending was 70-80 mm. For the ring after welding, the opening was 180 mm and for the rings expanded by 0.8%, 1.2% and 0.4% -58-53 mm. This indicates that the residual expansion stresses were much smaller than in the pipe after welding the seam, and the amount of expansion change from 0.4% to 1.2% does not affect the residual stresses. Scientific novelty. For the first time, for the JCOE technology of production of TVD from rolled hot-rolled sheet, the influence of expansion on residual stresses was determined experimentally. It was shown that the opening of the rings during expansion is significantly reduced. For the first time, the influence of the amount of expansion on the reduction of residual stresses was determined for the JCOE technology of TVD production. It is shown that deformations of 0.4-1.2% give the same opening of the rings after expansion. Practical significance. The obtained results can be useful for the personnel of steel welded TVD production enterprises and project organizations sn the design of oil and gas pipelines

Authors: Khlopenko M. , Polyvoda V. , Sharko O. , Onyshko D.
Published: September 2024

The object of the research is the processes of slamming automatic avoidance when the vessel is sailing in a storm. During stormy sailing, the vessel is subjected to external influences from wind and waves, which lead to strong dynamic loads on the hull, increase in heel and trim angles, flooding of the deck. The vessel's speed decreases, its controllability deteriorates. Slamming is one of the most dangerous phenomena in storm sailing. The appearance of slamming depends on many factors: the size and shape of the vessel's hull, the draft of the bow, the state of the sea, the vessel's course and speed. Slamming is characterized by impacts of the bow and the bottom of the vessel's hull against the water when moving towards waves, the length of which is approximately equal to the length of the vessel. Impacts are accompanied by body shaking, due to a sharp increase in the load on the bottom, and a slowly fading vibration. Hydrodynamic shocks on the bottom and general vibration are the reasons for the violation of the local and general strength of the hull. Slamming and other dangers of stormy sailing are the cause of strong psycho-emotional stress of boatmen, contribute to the accumulation of fatigue, which is a prerequisite for accidents. In the article, a method of automatic control of the vessel to prevent slamming was developed. The obtained results are explained by the use of an on-board computer, the construction of a dangerous area of slamming in on-board computer, the use of a gradient method of finding the optimal trajectory in time of the phase point output from the dangerous area, and the maintenance of the optimal trajectory by means of an automatic control system. The use of the developed method allows you to automatically avoid slamming, reduce the influence of the human factor on control processes, reduce crew fatigue, reduce the risks of losing the ship and cargo, and increase the safety of navigation. The developed method can be used on vessels, provided it is integrated into the existing automated system of the on-board computer to solve the problem of automatic avoidance of slamming during stormy sailing

Published: September 2024

The study is devoted to the development of a comprehensive approach to vibration diagnostics of the main power plant of water transport vehicles. The method of automatic processing of narrowband spectra is being improved. The method of automatic adaptation of threshold values for timely detection of changes in technical condition against the background of natural monotonous changes in vibration parameters characteristic of ship conditions is being improved. In the course of the study, the peculiarities of the spectra of vibration signals of rotary equipment were formulated and their analysis was carried out from the point of view of evaluating the parameters of diagnostically significant components. Automatic systems of centralized control and management are traditionally used to assess the current performance of SEU on ships. Their main purpose is to assess the quality of the SEU performance of the specified operating modes. But these systems do not allow solving the task of early prediction of the loss of performance of the most loaded and failure-prone SEU elements - rotary machines, because the controlled parameters of technological processes are either inertial and do not change synchronously with the development of faults, or do not react to the development of a number of dangerous defects until the onset irreversible consequences. The method of automatic diagnostics was further developed based on the results of monitoring vibration parameters of various nature and the assessment of the diagnostic significance of their changes against the background of natural monotonous fluctuations

The Death in their Eyes
Authors: Sánchez-Biosca Vicente
Published: September 2024

Images that embody the point of view of the perpetrators of violent crimes, or their accomplices, force us to look at the pain of victims through the eyes of those who caused it. Accompanied by over sixty visuals of historically infamous violence, The Death in their Eyes goes beyond the visible aspects of images to reveal what has been left outside of the frame. Covering human abuse and humiliation at Abu Ghraib, the Auschwitz Album, religious desecration during the Spanish Civil War, an unfinished Nazi propaganda film made at the Warsaw Ghetto in the spring of 1942, and detainees at the S-21 torture center in Cambodia under the Khmer Rouge, this volume proposes a rigorous new methodology for analyzing perpetrator images, in photography and film, that continue to be used and re-appropriated in today’s media.
Effects of Cold on the Adrenoreactivity of the Rat Superior Mesenteric Artery
Authors: Yartsev V. N.
Published: September 2024

In experiments on segments of the rat superior mesenteric artery (SMA) under isometric conditions, the effect of cold on the reactivity of this artery, estimated by the magnitude of the contractile reaction of its segments to noradrenaline (NA) at a concentration of 0.01–10.0 µM, as well as to electrical field stimulation (EFS) of perivascular nerves with a frequency of 3, 10 and 40 Hz in the absence and presence of NA in the medium and at a temperature of 37 oC or 25 oC was studied. Cooling was found not to change the tone of the SMA caused by NA at all the concentrations used. In the absence and presence of NA at a low concentration (0.01–0.10 µM), cooling leads to a significant decrease in the neurogenic response of the SMA at all frequencies of EFS, while in the presence of NA at a high concentration (1–10 µM), cooling has no statistically significant effect on this response. In the presence of NA at a low concentration, cooling at low EFS frequencies insignificantly, and at high frequency significantly reduces the potentiating effect of NA on neurogenic contraction of SMA. NA at a high concentration under normal temperature conditions, reduces the neurogenic contraction at all EFS frequencies, while under cooling conditions at low frequencies it has a potentiating effect, and at high EFS frequency it has a depressing effect. The results obtained show that the depressing effect of cold on the neurogenic constriction of the rat SMA, observed at low and disappearing at high concentrations of NA, as well as on the NA-evoked potentiation of the neurogenic vasoconstriction, is not associated with a decrease in the contractile effect of NA, which is the main neurotransmitter in this artery. These effects can contribute to the redistribution of blood from the surface deep into the body, thus reducing heat loss and improve thermoregulation.

Published: September 2024

Disturbances in the neurotransmitter systems during the development of temporal lobe epilepsy have been most detailed studied in forebrain structures – in the temporal cortex, amygdala, and hippocampus [1, 2]. It is known that during the formation of temporal lobe epilepsy in the model of audiogenic kindling there is a spread of epileptiform activity from brainstem to forebrain structures. However, the molecular mechanisms of neurotransmission dysregulation in the inferior colliculi in rodents with genetic prone to audiogenic seizures during epileptogenesis remain unknown. Changes in neurotransmitter systems of inferior colliculi may contribute significantly to the recruitment of forebrain structures during the initial stages of epileptogenesis.
The current work provides a comprehensive analysis of activity markers of glutamate- and GABA-ergic neurons in inferior colliculi of Krushinsky – Molodkina (KM) rats genetically prone to audiogenic seizures. A modified audiogenic kindling protocol was used to model the early stages of temporal lobe epilepsy development. In this protocol rats were subjected to daily audiogenic seizures for seven days. Naive KM rats were used as controls.
Although the rodent’s predisposition to audiogenic seizures is often associated with disruptions in GABAergic transmission, no significant changes were found in the expression of GABA synthesis enzymes or the α1 subunit of the GABAA receptor in the brains of KM rats, either 24 hours or a week after their last convulsive seizure. However, 24 hours after the last audiogenic seizure, an increase in glutamatergic transmission in the inferior colliculi was observed: the activity of ERK 1/2 kinases and the exocytosis protein synapsin 1 increased, as well as the expression of VGLUT1 and VGLUT2 and the synaptic protein SV2B. One week after the last seizure, only an increase in VGLUT1 content in the inferior colliculi was observed, suggesting that persistent changes occur in the neurons of forebrain structures, in particular, the temporal cortex.

BACKGROUND: The Test of Memory Malingering (TOMM) is a widely used performance validity measure that is available in both English and Spanish. The Spanish version, however, has historically lacked normative data from samples that are representative of the U.S. Hispanic/Spanish speaking population. OBJECTIVE: The aim of the current study was to collect normative data on the update TOMM 2 for Hispanic individuals residing in the U.S. METHODS: Normative data on the TOMM 2 was collected across 9 sites from different regions of the U.S. The total sample consisted of n = 188 cognitively healthy adults aged 18 and over with no current or prior history of neurological or psychiatric disorder. Descriptive analyses were performed on total raw scores. RESULTS: Participants obtained a mean score of 48.15 (SD = 2.81) on trial 1 of the TOMM 2, 49.86 (SD = 0.487) on trial 2, and 49.84 (SD = 0.509) on the recognition trial. Scores are provided for traditional cutoff scores as well as some popular cutoffs reported in the literature. Item level analyses were conducted as well as evaluation of performance based on a variety of demographics. CONCLUSION: When compared to the English-speaking normative sample used for the original TOMM, this sample demonstrated better performance on the TOMM 2 indicating better cultural appropriateness of the items. This is the first study conducted that provides culturally appropriate descriptive norms for use with Spanish speakers living in the U.S.

Abstract. Poultry meat is the most common type of raw meat, in demand among consumers, but at the same time a perishable product. The quality and safety of poultry meat during storage can be ensured by using bioactive film coatings. The scientific novelty of the work lies in the receipt of new scientific data on the effect of a bioactive alginate coating with protein hydrolysate on the performance of broiler chicken breast fillet during storage. The purpose of the research is to establish the effectiveness of a bioactive coating based on sodium alginate with protein hydrolysate as an active component during the storage of poultry meat. Research methods. For samples of broiler chicken breast fillet coated with bioactive alginate films and for a control sample without coating, color characteristics, pH, mass fraction of moisture and weight loss during storage, as well as microbiological indicators (total microbial count, and coliforms) were determined. The studies were carried out using standard generally accepted methods. Results. It has been established that coated meat better retains its appearance and color, the moisture content remains at a fairly high level compared to the initial value, and shrinkage is reduced. It was also found that the alginate coating provides microbiological stability of breast fillet for a longer time compared to the control sample: after 7 days of storage, the total microbial number in the control sample was 1.4 106 CFU/g, which is higher than the permissible level according to the requirements of EAEU TR 051/ 2021, while in alginate coating samples this indicator remained within acceptable values. Thus, film coatings based on sodium alginate with the addition of protein hydrolysate as an active component have the potential to ensure the safety and biosafety of poultry meat during storage.

The content of organic matter (humus) increases up to 4.2–5.5 % for the period of counting (4.0–4.7 % on the reference). Increase of moisture-holding capacity of soils in variants of experiment with tobacco dust and destructors was established (soil moisture for the period of research amounted to 18.4–25.5 %, in control – 17.1–18.7 %). The best results for surface composting of tobacco dust were obtained under wet conditions in 2021 (Hydrothermal coefficient (HTC) = 1.38), in 2020 HTC = 0.87. Mycological analysis revealed a decrease in soil infestation with pathogenic micro-mycetes in the variants of the experiment with tobacco waste. The increase in yield of bitter pepper (variety Baraniy rog) on the background of a mixture of tobacco dust and biodegraders amounted to 12–32 % (2020), seed cucumber (variety Dal’nevostochnyy 27) – 20–33 %.

ПАРАФРАЗ Ф. ЛІСТА «СПОГАД ПРО “ЖИДІВКУ”»: ДОСВІД ДРАМАТУРГІЧНОГО ПОРІВНЯННЯ
Authors: ШУМАКОВА Єлізавета
Published: September 2024

Метою статті є визначення музично-драматургічних особливостей парафразу Ф. Ліста. Методологічну основу дослідження склали історичний підхід, порівняльний метод, комплекс методів музикознавчого аналізу (композиційно-структурний, жанрово-стилістичний, драматургічний, інтерпретаційний). Наукова новизна статті полягає в розкритті драматургічних особливостей парафразу «Спогади про “Жидівку”» і введенні його до наукового обігу. В статті відзначено основні драматургічні положення опери Ф. Галеві «Жидівка» та драматургічні функції основних персонажів, окреслено їх індивідуальні характеристики. Комплексно проаналізовано парафраз Ф. Ліста за оперою Ф. Галеві. Охарактеризовано драматургію літературної поеми і виявлено її риси у творі Ф. Ліста. Проведено композиційний аналіз парафразу, визначено його загальну структуру (вступ, три розділи, фінал), структуру кожного розділу. Визначено запозичений з опери тематичний матеріал (тема прокляття Броньї з финалу ІІІ акту, вступ до V акту, тема святкового хору християн з V акту, «Болеро» Євдоксії з ІІІ акту), підкреслено інтонаційну спорідненість між темами охарактеризовано методи їх розвитку; відзначено, що наявність тематичних арок між розділами сприяє об’єднанню загальної композиції в єдине ціле (мотив смертного вироку і тема прокляття; тема всенародного свята). Звертається увага на переосмислення Лістом оперних персонажів і розстановку нових акцентів у драматургії парафразу; на цій підставі значно посилена драматургічна роль Евдоксії, яка стає центральною фігурою. Проаналізовано створення художніх образів парафразу, підкреслено використання віртуозності як засобу виразності. Методом комплексного аналізу встановлено, що Ліст в основу парафразу поклав одну з драматургічних ліній «Жидівки», яка пов’язана з жіночими образами. Кардинал Броньї виступає в парафразі як уособлення християнського закону. Автор статті пропонує різні інтерпретації розв’язання драматургічного конфлікту в парафразі Ліста які пов’язані з двома варіантами лібрето Е. Скріба і постановок опери у ХІХ столітті.
МИСТЕЦТВОЗНАВЧА ЕКСПЕРТИЗА ЯК ІНСТРУМЕНТ АТРИБУЦІЇ КУЛЬТУРНИХ ЦІННОСТЕЙ
Authors: ЗАБОЦЬКИЙ Володимир
Published: September 2024

Метою статті є окреслення сучасних проблем мистецтвознавчої експертизи, які обумовлені розвитком нових художніх практик у ХХ–ХХІ ст., нових технологій, зростанням арт-ринку та перетворенням колекціонування предметів мистецтва на важливу репутаційну та фінансову інвестицію. В обігу з’являються нові оригінальні твори, з якими експерти досі не мали справи, а також і вдосконалені підробки. У зв’язку з цим мистецтвознавча експертиза та одне з її основних завдань – атрибуція культурних цінностей, набули надзвичайної важливості: від результатів експертизи залежить визначення цінності і вартості досліджуваних об’єктів, дотримання прав їхніх авторів, репутація і вигода нових власників, продавців-посередників, а також авторитет музейних інституцій, які виступають не лише зберігачами культурної спадщини, а й еталонними експертними інституціями. Методологія дослідження ґрунтується на структурно-функціональному методі, який розглядає мистецтвознавчу експертизу та художнє, інституційне і ринкове середовище як тісно пов’язані явища. Наукова новизна роботи полягає в окресленні актуальних проблем та прогалин в українському мистецтвознавчому полі, у якому доволі мало приділяється уваги питанням експертизи творів сучасного мистецтва та актуальним проблемам українських художників, чиї роботи часом стають предметом суперечок з приводу атрибуції, порушення авторських і майнових прав. Висновки. Через появу нових мистецьких технік, розвиток нових технологій та зростання арт-ринку атрибуція культурних цінностей і предметів сучасного мистецтва зіштовхується з новими проблемами: майстерним фальсифікатом, новими матеріалами, з якими фахівці мають невеликий досвід роботи, а також значним тиском сторін, зацікавлених у однозначних результатах експертного дослідження. Розв’язанню цих питань сприятимуть постійний обмін досвідом з іноземними колегами, розширення навчальних програм, вироблення єдиних чітких стандартів експертної діяльності, які б враховували усе розмаїття художніх технік та практик, а також усі нюанси, пов’язані із захистом авторських та майнових прав.
La proposta di regolamento sul riconoscimento della filiazione tra Stati membri dell'Unione europea: l'ambito di applicazione e le regole sulla competenza giurisdizionale
Authors: Queirolo Ilaria
Published: September 2024

La proposta di regolamento dell'Unione europea sul riconoscimento della genitorialità tra gli Stati membri intende promuovere la certezza del diritto e la prevedibilità delle norme in materia di competenza giurisdizionale, legge applicabile e circolazione delle decisioni anche nel settore della filiazione. Tali obiettivi inseriscono in una materia (quella della circolazione degli status familiari) che presenta dei profili delicati e sulla quale risulta senz'altro difficile intervenire in modo "neutro". Lo scopo del presente contributo è di soffermarsi sull'analisi della proposta di regolamento, con particolare riguardo al suo campo di applicazione ed alla disciplina della competenza giurisdizionale. Quest'ultima, contenuta nel Capitolo II della proposta di regolamento, risulta variamente ispirata alle soluzioni già adottate negli altri regolamenti europei in materia di famiglia e successioni. Allo stesso tempo, la presenza di numerosi fori potenzialmente competenti presenta alcuni rischi di ridondanza e potrebbe compromettere alcuni dei sopracitati obiettivi del legislatore europeo.
