A major barrier to the clinical application of psychophysical testing of central auditory processes is the time required to obtain precise estimates of different listening abilities. In this study, we validate a novel adaptive scan (AS) method of threshold estimation that is designed to adapt on a range of values around threshold rather than on a single threshold value. This method has the advantage of providing the listener with greater familiarity with the stimulus characteristics near threshold while maintaining precise measurement and increasing time-efficiency. Additionally, we explore the time-efficiency of AS through comparison with two more conventional adaptive algorithms and the method of constant stimuli in two common psychophysical tasks: the detection of a gap in noise and the detection of a tone in noise. Seventy undergraduates without hearing complaints were tested using all four methods. The AS method provided similar threshold estimates with similar precision to those from the other adaptive methods and, thus, it is a valid adaptive method of psychophysical testing. We also provide an analysis of the AS method based on precision metrics to propose a shortened version of the algorithm that maximizes the time/precision tradeoff and can achieve similar thresholds to the adaptive methods tested in the validation. This work lays the foundation for using AS across a wide variety of psychophysical assessments and experimental situations where different levels of precision and/or time-efficiency may be required.
The Speech as a Crime: Writers under Attack by the People's Court. About the Second Wave of Terror after September 9, 1944
Authors: Doynov Plamen
Published: June 2023

The article examines the grounds, mechanisms and effects of the People's Court, through which the literary and media publicity in Bulgaria was transformed immediately after September 9, 1944, which led to a complete remodeling of the literary field. The general framework of prosecution through the institution of the People's Court is outlined, emphasizing how the written or spoken word becomes a criminal act and turns the writer and/or journalist into a criminal, and in the context of „people's justice“ turns its author in „public enemy“. Various cases of writers and journalists who were killed „without trial and sentence“, examples of writers who were convicted as ministers, as well as intellectuals who were brought before the Sixth Chamber of the People's Court were cited. The total number of convicted writers and journalists in Bulgaria in the winter and spring of 1945 is estimated at 150-170 people. Entire groups of authors disappear from the literary and media fields, and several ideological-thematic tendencies and genre-stylistic characteristics of literature fall into the zone of prohibition.
Language of Hate – Strategies for Manipulation: Discussion on Dunav Most / Serial Movie (1999) in Bulgarian Newspapers
Authors: Papuchiev Nikolay
Published: June 2023

The focus of the article is on the language of derogation and hate in Bulgarian news-papers published between 1990 and 2000. The study centers around one of the most famous and most discussed serial movies, “Dunav most” (The Danube Bridge). The 7-series visual project is based on Georgi Mishev’s novel and was sponsored by the Bul-garian National Television. Soon after the projection of the first episode started dis-cussion provoked by the most popular newspapers in the country, in which many jour-nalists, experts, political leaders, and citizens took part. The language of publications is a language of derogation and hate directed towards the movie and the “pornogra-phy” shown on it. So-called pornography is expressed in a few scenes with naked ac-tors and one – very popular and most argued - two men in a bed. One of them – a reli-gious man living in a monastery. Bulgarian newspapers manipulated the discussion pointing at that fact and hiding or diminishing the fact that this person had been an officer of former Secret services of the fallen totalitarian regime. The language of hate is paralleled with “the traditional Bulgarian values,” and in that way mass media present the distortion of a post-totalitarian society. Homosexuality is considered as a huge problem of the modern nation, and that is why it must be pointed at and rejected. This language, in fact, provokes readers’ emotions and turns aside attention from economic and social issues controlled by people of former totalitarian police.
Writer Fighting against Discrimination and Eastern Reality
Authors: Davitadze Tamila , Mazmishvili Nana
Published: June 2023

Discrimination against women and girls – including gender-based violence, harmful traditional practices – is the most common form of inequality. Giving preference, privileges to sons and underestimating girls, which is the main cause of the harmful practice of sex selection based on gender, is still a widespread practice in some countries. Against this background, the role and contribution of those politicians, writers and people interested in this issue, who, at the risk of their lives, fight to improve the situation, is invaluable. Among the people with their priceless input in promotion of the above mentioned issue, we would distinguish Jean Sasson, the modern American writ-er and researcher who considered the request of an Arab woman and turned her notes about real stories into an artistic reality. In the novel “The Princess’ Diaries,” the victim of discrimination asks for help, as there is no other way for her to change any-thing; however, she hopes the situation in her country will change for the benefit of women and as it is believed, fighting always makes sense. The objective of the given paper is to bring to light the form of expressing the protest against unfair reality by the victim herself. Moreover, we aim to draw a parallel between two women and the ways they communicate the harsh reality to the rest of the world.
Gender Marked Phraseologisms in Bulgarian – Aspects of their Semantics and Stylistic Marking
Authors: Stalyanova Nadezhda
Published: June 2023

The paper explores the language-society relationship in the context of gender-neutral language, a part of inclusive communication that aims to avoid referring to a person's gender while inappropriately highlighting or attributing positive or negative characteristics exclusively associated with one gender. The analysis is situated in the linguistic aspect of so-called gender-sensitive language or gender-neutral language. The text studies the semantics of two phraseologisms in Bulgarian perceived as discriminatory, negatively marked and suggesting gender stereotypes. In order to investigate and analyze the reception and use of the phraseologies мъжка дума (man’s word) and мъжко момиче (man like girl) by school-age youth, we conducted a survey among respondents between 15 and 17 years old. The aim of the study was to analyze to what extent young people perceive the connotative meaning of the phraseologisms, whether they realize their semantics as evaluative and characterizing a certain type of behavior. The questions in the survey are devoted to the stylistic and connotative meaning of the studied expressions. The findings of the study show that phraseologisms with a component indicating a person's biological sex and expressing a certain attitude towards its stereotypical perception in society are not part of the active vocabulary of the Bulgarian students. Young people experience difficulties in defining their semantics. The text predicts that their reduced use in the near future will not be the result of policies enforcing the principles of inclusive communication. These phraseologies will naturally pass into the passive part of the lexical system due to ignorance of their semantics.

The Administrative Burden of Public Sector Death Management
Authors: Zavattaro Staci M.
Published: June 2023

Administrative burdens emerge in citizen-state interactions, and one area with burdens for both providers and users is deathcare. Death managers deal with dirty work daily, so often suffer stigmatization. They also are often low resourced and face incredible burnout and stress. Families and loved ones face the burden of death-related paperwork and burial. This research draws on U.S. deathcare professionals’ knowledge to introduce dirty work costs to the existing administrative burden framework, while also offering a research agenda to uncover and ideally reduce administrative burdens for both citizens and death managers.

Authors: Sonita Helen , Zaini Erizal , Umar Salman
Published: June 2023

Ketoprofen is a non-steroidal anti-inflammatory compound (NSAID) which has low solubility in water. This study aimed to increase the dissolution rate of ketoprofen by forming multicomponent ketoprofen-glutamine in ratios of 1:1, 1:2, and 2:1 using the solid-state grinding method. The samples were characterized using Powder X-Ray Diffractometry (PXRD), Differential Scanning Calorimetry (DSC), Fourier Transform Infrared (FTIR) Spectroscopy, Scanning Electron Microscope (SEM), solubility, dissolution rate, and stability tests. These results indicated the formation of a eutectic mixture of ketoprofen-glutamine. From the study of the ketoprofen–glutamine eutectic mixture, the eutectic point at a ratio of 1:1 was obtained at 95.51°C. The PXRD spectra did not show new crystal habits; the solubility test of the eutectic mixture of ketoprofen-glutamine showed increases of 2.450, 2.518, and 2.374 times, respectively. The eutectic mixture of ketoprofen–glutamine had rod-like crystal particles that formed and aggregated. The samples showed an increased dissolution rate of ketoprofen. The stability test showed that ketoprofen-glutamine was stable during storage at 75% relative humidity (RH) and 40 °C for 6 months; there was only a decrease in intensity, as seen from the PXRD spectrum.
Keywords: eutectic mixture, ketoprofen, glutamine, solubility, dissolution rate, stability

Analysis of interrelation of productivity indicators and meat quality of pig hybrids (DxLxLW) (n=203) taking into account genotype of animals, stress factor and feeding complex of adaptogens was carried out on the basis of data array. The highest correlation were with ADG-CY (P<0.001), ADG-pH24 (P<0.01), BF1-BF2 (P<0.001), BF1-pH24 (P<0.001), pH45-pH24 (P<0.001), WHC-pH45 (P<0.01). The study of stressful environmental conditions showed their significant effect on all the parameters taken into account in the analysis: the ADG decreased by 7.53% (1005.80 g vs 1087.65 g in animals without stress; P<0.001), CY decreased by 3.12% (73.82% vs 76.94%; P<0.001), BF1 decreased by 12.83% (27.40 mm vs 31.43 mm; P=0.003), BF2 decreased by 16.39% (17.44 mm vs 20.86 mm; P<0.001), pH45 decreased by 3.87% (5.87 vs 6.11; P<0.001), pH24 decreased by 1.24% (5.51 vs 5.58; P=0.003). At the same time, WHC on stress increased by 3.73% (74.80% vs 71.07%; P=0.01). There was a significant (P<0.05) effect of SCD on CY and BF1, IGF2 on pH45 and MC4R on pH24. Factor group (K) with adaptogen had a positive effect (P<0.05) on growth rates, slaughter yield and production quality. By two-factor analysis, the effect of the studied adaptogen factor (dihydroquercetin complex with vitamins E and C) on pH45 value in animals with IGF2 genotype (P=0.005) was established. Thus, consideration of the genetic status of the animal and a set of measures involving the feeding of special substances-adaptogens for the prevention of the effects of stressors can improve the lifetime productivity and meat quality of hybrid pigs.

Authors: ELEMANA Nagehan
Published: June 2023

Osmanlı Devleti’nin; askeri, siyasi, idari, ekonomik ve sosyal tarih alanlarına dair çok sayıda araştırma yapılmıştır. Fakat ilmi hayat, âlimler ve eserleri genellikle arka planda kalmıştır. Bunun nedeni ise, İslam’da ilmi hayatın Abbasi Devleti’nden sonra gerilediği veya durağanlaştığı şeklindeki genel kanaattir. Taşköprülüzâde Ahmed Efendi tarafından kaleme alınmış olan eş-Şakâ’iku’n-Numâniyye fî Ulemâi’d-Devleti’l-Osmâniyye, Osmanlı âlimleri (1299-1566 yılları arasında) hakkında kısa bilgilerin verildiği biyografik bir eserdir. Bu çalışmada, Şakâ’iku’n-Numâniyye özelinde, Osmanlı âlimlerinin kaleme aldıkları eserler nitelik ve nicelik bakımından incelenecektir. Şakâ’ik’den elde edilen veriler, konuyu somutlaştırmak ve daha kolay anlaşılır kılmak üzere kantitatif bir yaklaşımla değerlendirilerek, mümkün olduğunca tablo ve grafikler vasıtasıyla sunulacaktır. Bu çalışmada, Osmanlı âlimlerinin kaleme aldıkları eserler tür ve konu bakımından neler ifade ediyor? Tür olarak telif eser mi ortaya koymayı tercih etmişlerdir yoksa şerh türü eserler mi kaleme almışlardır? Tercihlerinde neler etkili olmuştur? gibi soruların cevapları aranacaktır. Sonuç olarak bu veriler ışığında Osmanlı ilim hayatı ile ilgili bir kesit sunulmaya çalışılacaktır.
Osmanlı Devleti’nde Ehl-i Örf ile Ehl-i Şer’in Te’dib ve Ta’ziri
Authors: YILMAZ Savaş
Published: June 2023

Osmanlılar, fethettikleri coğrafyalarda değişik medeniyetlerin siyasi, kültürel özelliklerinin yanı sıra Oğuz Kağan geleneği ile Türk–İslam devletlerinin siyasi, idari, askeri ve mali yapılarından da etkilenmişlerdi. Gelenekten yeniliğe evrilen yönetim sistemlerini, doğmalara ve tekdüzeliğe teslim etmemişlerdi. Yeniliklere açık olmalarının yanı sıra örfî değerlere bağlılıkları da özgün bir medeniyet oluşturmalarını sağlamıştı. Böyle bir idari sistemin işlerliğinde ehl-i örf ile ehl-i şer’in yadsınamaz rolleri olmuştu. Bunların davranışları ise yazılı ve yazısız kurallarla belirlenmişti. Şer’î ve örfî hükümlere azami ölçüde uyulması, disiplin ve hiyerarşinin ön planda tutulması, devasa bir kadronun sevk ve idaresine işlerlik kazandırmıştı. XVI. yüzyılın ikinci yarısında; hiyerarşi ve disiplinin bozulması, örfî ve şer’î değerlere göre hareket edilmemesi, tebaada genel bir rahatsızlık oluşturmuştu. Merkezi yönetim, düzenin sağlanması için teftiş mekanizmasına işlerlik kazandırarak sorunları gidermeye çalışmıştı. Ancak arzların yoğunlaşması, te’dib ve ta’ziri gerektiren hallerin önlenemediğini göstermekteydi. Bu durum merkezi yönetimin taşra idaresinde kanun-ı kadîmin bozulmasıyla gücünü ve etkisini kaybetmeye başladığını; bu durumdan yararlanan, ehl-i örf ile ehl-i şer’in ise görev ve yetkilerini suiistimal ederek ek gelir sağladıklarını ortaya koymaktaydı. Bu bağlamda ehl-i örf ile ehl-i şer’in te’dibinden, ta’zirine kadar ki süreçte; hukuk kurallarına bağlı kalınması ile kalınmamasının, yönetim sistemindeki olumlu ya da olumsuz yansımalarının anlaşılması bakımından bu konunun anlaşılması gerekmiştir. Kanunî’den, III. Mehmet’e kadar ehl-i örf ile ehl-i şer’in kanuna ve töreye uymayan halleri ile bunlara uygulanan cezalar, divana sunulan arzlar bağlamında araştırıldığı için mühimme defterleri asıl kaynak olarak kullanılmıştır.

Objective: To describe the prevalence of depression among medical students during the fourth wave of COVID-19 in Vietnam and its association with participation in working frontline. Methods: A cross-sectional study using an online questionnaire with a convenience sample of Hanoi Medical University students who were mobilized to support the frontline of the fight against COVID-19 was conducted. The study collected information regarding participation in the frontline and the mental health disorders using the Depression, Anxiety, and Stress Scale (DASS-21). Descriptive analysis, univariate linear and multivariate regressions were performed. Results: Over 16% of our sample reported mild to extremely severe depression. Almost two- third of participants of this group reported comorbidity for anxiety and stress. Findings indicated that depressive symptoms were negatively correlated with field tracing and testing work in the frontline. Conclusion: Our findings highlighted the relatively high prevalence of depression and the potentially high mental health problem comorbidity among frontline medical students in Vietnam. Consequently, we recommend further research on frontline medical students, developing better workplace environment, appropriate interventions that address the link between depression and participation in the frontline, and trainings for junior healthcare workers.

Due to the substantial development of information and communications technology, the use of E-learning in higher education has become essential to boost teaching methods and enhance students' learning skills and competencies. E-learning in Software Engineering turns out to be increasingly interesting for scholars. In fact, researchers have worked to enhance modern Software Engineering education techniques to meet the required educational objectives. The aim of this article is to analyse the scientific production on E-learning Software Engineering education by conducting a bibliometric analysis of 10,603 publications, dating from 1954 to 2020 and available in the Scopus database. The results reveal some scientific production information, such as the temporal evolution of the publications, the most prolific authors, institutions and countries, as well as the languages used. Besides, the paper evaluates additional bibliometric parameters, including the authors' production, journal productivity, and scientific cooperation, among other bibliometric parameters. The subject of the current study has not been treated by any previous bibliometric studies. Our research is deeper and more specific; it covers a long period of 66 years and a large number of publications, thanks to the chosen search string containing the different spellings of the used terms. In addition, the literature is analysed using several tools such as Microsoft Excel, VOSviewer, and Python. The research findings can be used to identify the current state of E-learning Software Engineering Education, as well as to identify various research trends and the general direction of E-learning research.

Published: June 2023

Background:

This study aims to examine the rare entity of unilateral macular lesions in the pediatric population and describe the distinct diagnoses and characterizations related to these findings.

Methods:

A retrospective cohort design. The database of the ophthalmology clinic in a tertiary medical center was reviewed to identify all children with incidental unilateral macular findings, examined during 2016 through 2021.

Results:

Twenty children were included. Mean age was 7.8 ± 3.4 years, 50% were girls. The most common macular lesion was torpedo maculopathy (50%), followed by pigmentary changes (25%), discoid maculopathy (15%), macular scar and combined hamartoma of the retina and retinal pigment epithelium (RPE) (5% each). None of the lesions changed after a mean follow-up duration of 2.3 ± 1.5 years. Visual acuity in the involved eye was equal to that in the contralateral eye in 90% of patients and did not change from initial to final visit.

Conclusion:

Incidental unilateral macular lesions in the pediatric population are usually benign, stable, and do not affect vision. Long-term follow-up is advised, as vision-threatening alterations may appear.

PSO-MCKD-MFFResnet based fault diagnosis algorithm for hydropower units
Authors: Li Xu , Xu Zhuofei , Wang Yimin
Published: June 2023

Due to the coupling effect of external environmental noise and vibration noise, the feature rate of the original hydroelectric unit fault signal is not prominent, which will affect the performance of fault diagnosis algorithms. To solve the above problems, this paper proposes a PSO-MCKD-MFFResnet algorithm for fault diagnosis of hydropower units (Particle swarm optimization, PSO; Maximum correlation kurtosis deconvolution, MCKD; Multi-scale feature fusion residual network, MFFResnet). In practical applications, the selection of key parameters in the traditional MCKD method is heavily dependent on prior knowledge. First, this paper proposes a PSO-MCKD enhancement algorithm for fault features, which uses the PSO algorithm to search for the influencing parameters of MCKD to enhance the features from the original fault signal. Second, a fault feature diagnosis algorithm based on MFFResnet is proposed to improve the utilization of local features. The multi-scale residual module is used to extract features at different scales and then put the enhanced signal into MFFResnet for training and classification. The experimental results show that our approach can accurately and effectively classify the fault types of hydropower units, with an accuracy rate of 98.85$ % $. It is superior to other representative algorithms in different indicators and has a good stability.
Didactic Strategies for Meaningful Learning

Published: June 2023

This work aims to analyze and explain the didactic strategies used to achieve meaningful learning. It begins under the assumption that meaningful learning is created if students are given freedom and confidence; they can find their answers and develop their knowledge, both in the classroom and in practical life. The method used is the analytical-descriptive one of the reviews of the literature of the main authors who have given rise to this approach, its elements, and the didactic strategies used. It is concluded that the design and implementation of didactic strategies focused on meaningful learning with the application of active didactic methodologies and strategies in meaningful learning processes depending on the context in which it takes place, obtains better results in the training of professionals.
The Triumph of Bi-Racial Identity
Authors: Kwabena Moss Andrew
Published: June 2023

This chapter utilises an autobiographical and creative approach that links cultural history to the education children receive in the classroom. I present a narrative account of my personal story as a child of mixed racial identity as well as mixed cultural identity to explicate the range of emotions, the expanse of experiences evoked by racial hostility and the child's response as he navigates this landscape and journey towards making sense of these experiences in the shaping of his identity. This chapter is grounded in funds of knowledge theory, identity theory and culturally relevant theory. The process of the building and resulting production of my own funds of knowledge challenge the validity of the traditional Eurocentric Western epistemologies that shaped the education I received in the British classrooms of my youth. From this investigation, I have come to the conclusion that bi-racial children have the benefit of a rich, three-dimensional, dual heritage which provides a much-needed emotional foundation that allows them to thrive even within hostile settings. Teachers face the challenge of recognising, acknowledging and tapping into this gourd of cultural capital and effectively using it to heighten students' performance and guide them on the path to academic achievement.
MobiKwik

Published: June 2023

Bipin Preet Singh and Upasana Taku, the power couple of the FinTech world, had sought to differentiate their wallet company by turning it into a microloan disbursement platform. Simultaneously, they had been extending the number of physical stores that accept MobiKwik payments. Mobikwik's image suffered a big blow in February 2021 when it was reported to have compromised the KYC details of over 3.5 million users, in addition to making personal details of 100 million phone users public, which landed the startup on the radar of the regulator Reserve Bank of India following an RTI (Right to Information Act 2005) petition. This also had an impact on its future IPO. The markets had not been receptive to FinTechs accessing capital markets, and its competitor company Paytm's IPO was a disaster.

The Fall of Yes Bank
Authors: Sarangal Ruhi , Kaur Maninder , Kumar Ashok
Published: June 2023

This case study focuses on a major challenge faced by Yes Bank as a result of increasing NPAs, a 30-day moratorium imposed by the RBI on its operations, and withdrawal limits of Rs. 50,000 from their accounts. This situation downgraded the value of the bank and built a bad image among its customers. Yes Bank was the UPI companion for almost 20 apps, according to the National Payments Corporation of India (NPCI). However, as a result of its failure, Yes Bank has suspended most of its UPI accounts. Now the government is trying to fix the problem and looking into what went wrong at Yes Bank. Altman's Z-Score, developed by American professor Edward Altman in 1968, is a numerical measurement that can be used to predict the chances of bankruptcy, and after calculating the z-score, it is possible to conclude that Yes Bank is still safe from going bankrupt.

Published: June 2023

Safety stock and safety time are two well-known stock buffering solutions of material requirements planning (MRP) processes to mitigate against supply and demand uncertainty. While the significance of proper inventory in managing change has been extensively researched, supply chain management research on safety period has gotten less attention. Earlier operations quantitative studies, in particular, have often evaluated the utilization of such stock buffers separately, rather than combined. Considering dynamic demands and stochastic timescales, the authors present the decision support system (DSS) that handle the efforts to integrate appropriate safety stock and safety time judgments at the system level in multi-item single-stage multi -supplier industrial supply chains. The DSS concept is formulated as a mixed bi-objective approach that optimizes upstream storage costs and -service levels at the same time, presenting decision-makers with alternative not dominated feasible solutions.
An Assessment Framework for the Maturity of Simulation-Based Verification
Authors:   Lockheed Martin - Sikorsky, Stirgwolt Ben , Keomany Stephanie
Published: June 2023

Simulation-based verification is a term that promises to reduce lengthy and costly ground and flight tests of aircraft, using high-fidelity physics-based simulations instead of testing physical assets. There has been considerable research into building more robust aircraft models that accurately depict the physics of an operational aircraft. The focus has been on the 'simulation-based' portion of the phrase 'simulation-based verification.' However, to achieve the full benefit of simulation-based verification, the focus needs to include how these physics-based simulations can be incorporated into an organization's requirements verification activities, which are traditionally the responsibility of the systems engineering organization. Over the last decade, systems engineering has been transforming into a 'model-based' discipline, where all systems engineering data is contained in a model of the system, including requirements and their properties. With a drive toward simulation-based verification, there is a need to incorporate the results of simulation-based verification into the system architecture model that contains the system's requirements. By integrating physics-based simulation into the system architecture models, organizations can build a robust verification story and to automate the requirements verification process. However, an organization does not simply transform from a traditional, physical test-based organization into a simulation-based organization; it is an evolutionary process. This paper describes a framework for assessing the maturity of an organization's simulation-based verification capabilities, with the highest level of maturity having physics-based simulation integrated into the model-based systems engineering verification process.

Published: June 2023

A Modular Open Systems Approach (MOSA) is an integrated business and technical strategy for assessing and implementing open systems in the Department of Defense (DoD) and beyond. An open system is a system that employs modular design tenets, uses widely supported and consensus-based standards for its keyinterfaces, and is subject to Validation and Verification, including Test and Evaluation, to ensure the openness of its key interfaces. The Army PEO Aviation MOSA Implementation Guide defines MOSA as follows:
SmartHangars and SAE International Aircraft Charging Standards
Authors:   Electro.Aero Pty Ltd, Portlock Joshua , Watson Richard
Published: June 2023

Electro.Aero has been supporting the emerging electric aviation industry for nearly a decade, including the development of chargers, electrical management systems, battery management systems and electric propulsion systems to numerous electric aircraft development projects. During that time, it was identified that the industry needed standardization, especially regarding the charging coupler, so the SAE AE-7D committee was founded by Joshua Portlock in 2018 to help standardize electric aircraft charging and energy management. While the charging coupler standard was proving to be of high priority to the industry, there has also been a noticeable trend that typical airport hangars do not have sufficient electrical power to charge the growing power demands of future electric vertical take-off and landing (eVTOL) aircraft. Therefore, SmartHangar technology was developed, whereby the limited grid connectivity is supplemented by solar and stationary battery energy storage systems to help deliver the peak power demands of electric aviation charging, whilst also helping airports and vertiports transition to more self-sufficient sustainable energy.
Quantitative Risk Assessment of Component Retirement Time Reduction
Authors:   Sikorsky a Lockheed Martin Company, Pham Loan , Hewitt John
Published: June 2023

In order to ensure safety and compliance with airworthiness regulations, demonstration of fatigue service life by testing and analysis is typically required for mechanical components on vertical flight aircraft. The resulting service lives often result in establishment of component retirement times that are approved by the airworthiness certification or military qualification authority. In some cases, reduction of the original component retirement times becomes necessary, even if no failures have occurred in operation. This may result from the application of newer fatigue service life testing and analysis methods to components that were developed many decades ago, or discovery that the components in operation differ from the analyzed designs. Quantitative Risk Assessment is typically used as a means of assessing and managing fleet risk for components that have failed or if signs of potential failure have been observed on components in operation. However, if a reduction in component retirement life becomes necessary, a new method of applying Quantitative Risk Assessment can assess fleet risk and possibly be applied to reduce risk before any field failures have occurred.
Finite Element Analysis and Test of a Sharp Radius on the Shank of a Ring Locked Stud
Authors:   Sikorsky a Lockheed Martin Company, Liu Lin , Binney David
Published: June 2023

This paper is an expansion on a prior paper in which the authors detailed an analytical approach to determining the effect of a sharp radius on the fatigue life of a ring locked stud. Fatigue testing of several studs has since been completed and the test results are compared with analytical predictions. Using the stresses determined by a validated finite element (FE) model, three methods of life calculation, stress life, strain life, and the theory of critical distances (TCD) point method, are evaluated in light of the test results. The stress life method is found to be inapplicable since there is no reliable Kf data for the high Kt levels in question. Strain life results are conservative relative to the test. The TCD may provide more accurate life results without the conservatism of strain life, but current test results do not support its use. The idea that small non-propagating cracks may exist at the sharp radius, below some threshold of alternating stress, is also discussed. In addition, the test program revealed that the installation depth of studs can potentially affect their fatigue strength.

Published: June 2023

With the aim of investigating whether sustainable and environmentally friendly flax fiber reinforced composites can meet the high technical requirements of aeronautical structures, this paper presents the influence of temperature and humidity on their structural-mechanical properties using protective coatings. Four coatings, two of which are partially bio-based, are tested on unidirectional flax fibers reinforced with bio-epoxy and polyfurfuryl alcohol resin. To simulate environmental conditions, coated and uncoated test panels are conditioned for two weeks in a climatic chamber at different temperature and humidity levels before their tensile specimens are tested and evaluated for moisture absorption, tensile strength, Young's modulus and fracture strain. The results show that higher temperatures lead to an increased moisture absorption rate and a lower maximum uptake. Higher relative humidity results in an increased maximum moisture uptake. A fossil-based coating could significantly reduce and retard moisture uptake at 30° C and 95 % relative humidity.

Published: June 2023

Carbon fiber reinforced epoxy composites are being increasingly used for load bearing structural elements in large transport rotorcraft. However, due to the increased stiffness-to-density ratio of composites, problems associated with vibration and interior noise can be exacerbated by the use of composites in airframes. The current investigation explores the potential of optimized composite meta-structures to reduce vibration and interior noise in rotorcraft. The approach involves designing a taper into the thickness of blade stiffeners which, when combined with a limited amount of absorbing material in the thinned region, creates what is known as an 'acoustic black hole' (ABH) in the stiffener. It is hypothesized that optimally designed ABH stiffeners can reduce broadband vibrations in stiffened panels. An optimization routine has been developed to determine the tradeoffs between vibration, mass, and buckling load due to compression parallel to the stiffeners. The tradeoffs are visualized using a 3-D Pareto front that helps the designer decide on the optimal design. Carbon/epoxy panels were made using vacuum-bag-oven processing with out-of-autoclave prepreg and verified to be of good quality. Panel vibration, buckling onset, and post-buckling load-deflection behavior were simulated using finite elements and measured using model testing and compression testing. Based on preliminary results, ABH-tapered stiffened panels have the ability to reduce radiated noise without a significant penalty in the mass and compressive load-bearing capability.

We aimed to compare psychiatric hospital visits during the COVID-19 quarantine period with the same period in 2019, to reveal the predictors of underutilization of mental health services. We then investigated the fluctuation of telemedicine service during the quarantine period. The retrospective study included patients with non-psychotic mental disorders who consecutively visited the Moscow clinic. The number of outpatient visits, inpatient admissions, sociodemographic factors were analyzed. We assessed the sample within two periods - the “quarantine period” (March 30 - June 9, 2020) and “control period” (March 30 - June 9, 2019). Psychiatric visits decreased in older, retired and disabled persons, and increased among the unemployed. In multivariate analysis, the reduction became significant for the number of inpatient admissions. Telemedicine calls gradually increased from the start of the service, but decreased towards the end of the quarantine. In conclusion, referrals to outpatient and inpatient psychiatric services decreased during the quarantine period, with newly established TMS potentially compensating for that decrease. The strongest factor associated with visits during the pandemic is employment status.
