Classic Theories of Nationalism in the Context of Minority Nationalism in Great Britain:regional nationalist movements as a “marginal” subject of modern historiography of nationalism
Authors: Kyrchanoff Maksym Waler'evich
Published: December 2023

The purpose of this study is to analyze the possibility of classical theories of nationalism use in analysis of the minority nationalisms histories in the British historiographical situation. The author analyses the complexities of integration and assimilation of the ideal models of Ruritania and Megalomania as imagining nationalising and modernising societies proposed by Ernest Gellner, as well as Miroslav Hrochs’ periodisation of nationalism as “ideal” interpretive models in the contexts of British historiography. The subject of the article is classical modernist theories of nationalism, the object is the possibility of their application in British historical research. It is assumed that the processes of nationalist modernisation and the development of regional nationalisms, on the one hand, are perceived through the prism of a constructivist approach. On the other hand, the author believes that the British historical material is characterised by a significant degree of resistance and therefore the use of classical theories of nationalism in the context of the conservatism of the historiographical imagination in Great Britain is debatable. The article analyses the difficulties of integrating the history of regional minority nationalisms and English nationalism into the contexts of sociocultural modernism of classical theories of nationalism. The results of the study suggest that the modern British historiographical situation is simultaneously characterised by an interest in the problems of the social history of regional nationalisms and significant conservatism, which expresses itself in ignoring classical theories of nationalism, despite the effectiveness of their interpretive models.

Published: December 2023

This research is a type of quantitative descriptive data survey research that aims to analyze the effect of anxiety levels on handball athletes at Singaperbangsa University in Karawang. The research method used is data collection filling out questionnaires to 10 handball athletes, of which 80% are male athletes and 20% are female athletes. The age of respondents was mostly the adult group (20-27 years) as much as 60% and the youth group (15-19 years) as much as 40%. Data collection is done through Google Form which consists of 26 statements using a Likert scale. The survey research results of the processed questionnaire data show the average value is 80.50 with a significant normality test of 0.996. The results measured in this study have been tested for validity and reliability has been confirmed previously. The conclusion from handball is that sport psychology has a very important role in understanding and managing athletes' anxiety. This anxiety can arise from match pressure, performance anxiety, and psychological factors that can affect athletes. However, by using sport psychology approaches, including mental training, support from teammates, and emotional management, athletes have the ability to overcome such anxiety. Therefore, controlling anxiety in sport is not impossible, and athletes can optimize their performance.

Authors: Cuba Avril Alys , Albina Albert , Jamandron Novie John , Sartin Edielyn , Rivera Jake Patrick
Published: December 2023

This present study aimed to explore the lived experiences of parents and elementary teachers with undernourished children or pupils. These pupils are enrolled in two elementary schools in the 4th District of Santa Catalina under the Division of Negros Oriental, Philippines. Employing the descriptive phenomenological design through the unstructured in-depth interview method on the experiences of teachers and parents with undernourished schoolchildren, twelve participants agreed to participate in this study. Digitally recorded interviews were thematically analyzed to generate the themes and subthemes. We generated four themes: (a) pupils' poor class performance and behavior; (b) teachers' strategic initiative aimed at enhancing performance and behavior; (c) Department of Education’s (DepEd) support for pupils' well-being; and (d) children's poor eating behavior. Teachers were challenged in handling pupils who are undernourished as the latter becomes mentally and physically absent in the classroom. To ensure that these pupils are not left behind, teachers make some interventions, like peer tutoring, to help the pupils cope with every day’s lesson. With the intention of improving the nutritional status of undernourished pupils, schools implemented the school-based feeding program and the giving of nutritious foods that may be brought home for pupils’ breakfast or supper. We conclude that despite the challenges encountered, teachers and parents devise interventions to lessen the negative effects of undernutrition with the help of DepEd.

Métodos: Revisão Integrativa da Literatura. A pesquisa se iniciou baseada na pergunta investigadora “Qual a eficácia do bloqueio anestésico com ropivacaína em plexo braquial interescalênico e a melhor via de administração, no controle da dor pós operatória de ombro em pacientes adultos?”. O levantamento eletrônico foi realizado nas bases de dado eletrônicas LILACS e Pubmed. Resultados: Os pacientes que receberam analgesia com ropivacaína relataram melhora satisfatória no período de pós operatório. Considerações finais: O bloqueio de plexo braquial interescalênico com ropivacaína para o controle da dor pós operatória pode ser considerado eficaz independente do gênero, idade ou de valores antropométricos. Os autores concordam que, a utilização da substância diminui a necessidade do uso de opióides. A adição de dexametasona perineural à ropivacaína parece tornar ainda mais eficaz o bloqueio no sentido de promover melhora álgica (prolongamento do bloqueio) e menos incidência de náuseas e vômitos. A adição de tramadol a ropivacaína parece tornar o bloqueio mais eficaz, diminuir o tempo de início e a duração do bloqueio sensorial.

Bilateral posterior fossa chronic subdural hematoma as a cause of hydrocephalus
Authors: Dlaka Domagoj , Marčinković Petar , Raguž Marina , Romić Dominik , Orešković Darko , Chudy Darko
Published: December 2023

Background:

Infratentorial chronic subdural hematoma (cSDH) is still a rather elusive neurosurgical entity, which, due to its proximity and likely compression of the cerebellum and brainstem, can lead to devastating consequences. To establish standardized treatment, more studies and reports regarding its therapy are needed. We report a case of a simultaneous unilateral supratentorial and bilateral infratentorial cSDH, with the latter causing hydrocephalus and successfully treated with a bilateral burr-hole trepanation of occipital bone and placement of subdural drains.

Case Description:

A 71-year-old man with gait disturbance, Glasgow Coma Scale 12, and a radiologically verified unilateral supratentorial and bilateral cSDH of the posterior fossa causing cerebellum, brainstem, and fourth ventricle compression with obstructive hydrocephalus, underwent surgical evacuation of infratentorial hematoma with a bilateral burr-hole trepanation. The postoperative course was uneventful, with a control head computed tomography scan showing the resolution of the hematoma and hydrocephalus. The patient was discharged with no newly acquired neurological deficits.

Conclusion:

Due to a limited number of reports and studies involving infratentorial cSDHs causing hydrocephalus, decision-making and optimal surgical treatment remain unclear. We recommend a timely surgical evacuation of the hematoma if the patient is symptomatic while avoiding placement of external ventricular drainage.

Janus SEGPHOS: Integrating Persistent Photogenic Radicaloids with Multiple Circularly Polarized Doublet Radiance and Long-persistent Triplet Phosphorescence

Published: December 2023

Organic phosphors integrating circularly polarized persistent luminescence (CPPL) across the visible range are prevalent for applications in optical information encryption, bioimaging, and 3D display, but the pursuit of color-tunable CPPL in a single-component organics remains a formidable task. Herein, via in-suit photo-implanting radical ion-pairs into axial chiral crystals, we present and elucidate an unprecedented double-module decay strategy to achieve a colorful CPPL through a combination of stable triplet emission from neutral diphosphine and doublet radiance from photogenic radicals in an exclusive crystalline framework. Owing to the photoactivation-dependent doublet radiance component and an inherent triplet phosphorescence in the asymmetric environment, the CPL vision can be regulated by altering the photoactivation and observation time window, allowing colorful glow tuning from blue and orange to delayed green emission. Mechanism studies reveal that this asymmetric electron migration environment and hybrid n-π*, π-π* instincts serve an afterglow and radical radiance at ambient conditions. Moreover, we demonstrate the applications of colorful CPPL for displays and encryptions via manipulation of both excitation and observation time.
Is Unsupervised Machine Learning Sufficient to Decode the Complexities of Electrochemical Impedance Spectra?
Authors: Makogon Aleksei , Kanoufi Frédéric , SHKIRSKIY Viacheslav
Published: December 2023

As electrochemical research undergoes rapid technological progression, the acquisition of substantial amounts of electrochemical impedance spectra (EIS) becomes increasingly feasible. Yet, this advancement introduces intricate challenges in data processing, automation, and interpretation. This paper delves into the sufficiency of unsupervised machine learning (ML) in decoding EIS complexities, examining its strengths, limitations, and potential pathways for optimization. As we navigated the intricacies of non-linear dimensionality reduction, spotlighting t-distributed stochastic neighbor embedding (t-SNE) and uniform manifold approximation and projection (UMAP) algorithms, a pattern emerged: these techniques excel at categorizing divergent impedance spectra but show limitations when faced with analogous circuit configurations, especially those substituting a capacitor with a constant phase element. This observation not only underscores a limitation but also accentuates that unsupervised ML approaches, alone, may not fully unravel the nuances of EIS spectra. In the concluding section of our manuscript, we discuss the implications of this finding from a practical standpoint, particularly for electrochemists seeking to apply these methods in their work.
Breakdown of Langmuir Adsorption Isotherm in Small Closed Systems
Authors: Zangi Ronen
Published: December 2023

For more than a century, monolayer adsorptions in which adsorbate molecules and adsorbing sites behave ideally have been successfully described by Langmuir adsorption isotherm. For example, the amount of adsorbed material, as a function of concentration of the material which is not adsorbed, obeys Langmuir's equation. In this paper we argue this relation is valid only for macroscopic (large enough) systems. However, when particle numbers of adsorbate molecules and/or adsorbing sites are small, Langmuir's model fails to describe the chemical equilibrium of the system. This is because the kinetics of forming, or the probability of observing, occupied sites arises from two-body interactions, and as such, ought to include cross-correlations between particle numbers of the adsorbate and adsorbing sites. The effect of these correlations, as reflected by deviations in predicting composition when correlations are ignored, increases with decreasing particle numbers and becomes substantial when only few adsorbate molecules, or adsorbing sites, are present in the system. In addition, any change that augments the fraction of occupied sites at equilibrium (e.g., smaller volume, lower temperature, or stronger adsorption energy) further increases the discrepancy between observed properties of small systems and those predicted by Langmuir's theory. In contrast, for large systems these cross-correlations become negligible, and therefore when expressing properties involving two-body processes, it is possible to consider independently the concentration of each component. By applying statistical mechanics concepts, we derive a general expression of the equilibrium constant for adsorption. It is also demonstrated that in ensembles in which total numbers of particles are fixed, the magnitudes of fluctuations in particle numbers alone, can predict the average chemical composition of the system. Moreover an alternative adsorption equation, predicting the average fraction of occupied sites from the value of the equilibrium constant, is proposed. All derived relations and predictions were tested against results obtained by Monte Carlo simulations.

The impact on the natural characteristics of dairy products during thermal processing warrants the investigation of non-thermal techniques. Ozone has not only arisen as an inactivation treatment for milk and its products with minimal effects on the quality parameters. But has also been proven efficient for reducing biofilms, antibiotics, and aflatoxins, and used for equipment sterilization, air disinfection, sanitization, and de-sludge treatments. This review discusses the updates on the effect of ozone processing on the microbiological, physiochemical, nutri-functional, and sensory quality of milk and milk products. Other applications of ozone in the dairy processing sector (storage rooms disinfection, wastewater treatment, benefits in CIP, toxin reduction), current industrial scenario, and regulatory and safety requirements in the facility dealing with ozone have also been discussed alongside the research gaps and challenges.

Published: December 2023

The photocatalytic efficiency of monolayer materials can be significantly enhanced by constructing two-dimensional van der Waals heterostructures. This study presents first principles calculations based on density functional theory to investigate the electronic properties and photocatalytic mechanism of van der Walls heterostructures of boron arsenide (BAs) with the Janus MXY (M=W; X/Y=Se, Te) monolayers, with and without Se vacancies. Results from binding energies, phonon spectra, and ab initio molecular dynamics simulations indicate that the heterostructures are stable from all respects. Moreover, all the heterostructures exhibit direct bandgaps with valence band maxima and conduction band minima suitable for water splitting. Additionally, these heterostructures possess high optical absorption coefficients in the visible and ultraviolet regions. In particular, our calculations predict BAs/WTeSe, with and without Se vacancies, as promising candidates for photocatalytic water splitting applications.
A Colorimetric Method for Naked-eye Detection of 6PPD in Rubber Products and Wastes
Authors: Li Zhuoyuan , Xie Linna , Nair Pranav , Tao Juan , Hiki Kyoshiro , Hao Chunyan , Peng Hui
Published: December 2023

N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) has received increasing attention due to its ubiquitous environmental occurrence and the extreme aquatic toxicity of its quinone oxidation product. Given 6PPD's application as an antioxidant in a wide array of rubber products and wastes, cost-effective measurement of 6PPD is important for product and waste management. We herein developed a naked-eye colorimetric method for the rapid measurement (<10 min) of 6PPD in rubber products and wastes with low cost (<$1 per sample). The inspiration for this method stems from the observation of the formation of red-colored products when 6PPD is exposed to oxidants, at concentrations as low as 0.65 mg/L. The remarkable selectivity of the method was evaluated by 15 other structurally diverse phenols and anilines. LC-UV and mass spectrometry results corroborated N-1,3-dimethyl butyl-N’-phenyl quinone diamine (6QDI) as the primary oxidation product. Interestingly, we discovered that the protonated form of 6QDI, rather than its neutral counterpart, was the red-colored reaction product with λmax = 490 nm. We further validated the method by applying it to the measurement of 6PPD in a wide array of rubber products and wastes, with 6PPD detected in 22 out of 50 samples. Strong agreement was observed between the colorimetric method and LC-MS measurements, with the highest concentrations detected in car tire rubber. In summary, this study introduces a rapid and cost-effective approach for rapid screening of 6PPD in rubber products and wastes.
Automating the relationships between printing companies and their stakeholders
Authors: Andriushchenko Tetiana
Published: December 2023

The dynamic development of the printed goods market requires ensuring manageability and flexibility of printing business. Nowadays any printing company needs to meet stakeholders’ requirements. Moreover, it should constantly monitor, analyze and assess their satisfaction. But monitoring and analysis without a quick and proper response to stakeholders’ actions do not always bring the required results. Evaluating the competitiveness of a printing company can help it to keep up with the competition. The integration of a decision support system into the automated system of a printing company will allow it to make informed decisions. Maintaining the customer-oriented nature of a printing company requires the usage of modern technologies and the leading place among these technologies belongs to CRM systems. Automated systems based on CRM technologies are present in the market of printing services, but none of them makes it possible to improve the efficiency of the relationship between a printing company and its stakeholders. Therefore, the development of the system that would meet all the requirements of a printing company and support the effective decision-making process is quite relevant.
Non-Operative Rehabilitation Principles for Use in Individuals with Acetabular Dysplasia: A North American Based Delphi Study
Authors: Disantis Ashley E. , Martin RobRoy L. , Enseki Keelan , Spaid Victoria , McClincy Michael
Published: December 2023

Background

Acetabular dysplasia (AD) is defined as a structurally deficient acetabulum and is a well-recognized cause of hip pain in young adults. While treatment of severe AD with a periacetabular osteotomy has demonstrated good long-term outcomes, a trial of non-operative management is often recommended in this population. This may be especially true in patients with milder deformities. Currently, there is a paucity of research pertaining to non-operative management of individuals with AD.

Purpose

To present expert-driven non-operative rehabilitation guidelines for use in individuals with AD.

Study Design

Delphi study

Methods

A panel of 15 physiotherapists from North America who were identified as experts in non-operative rehabilitation of individuals with AD by a high-volume hip preservation surgeon participated in this Delphi study. Panelists were presented with 16 questions regarding evaluation and treatment principles of individuals with AD. A three-step Delphi method was utilized to establish consensus on non-operative rehabilitation principles for individuals presenting with AD.

Results

Total (100%) participation was achieved for all three survey rounds. Consensus, defined a piori as > 75%, was reached for 16/16 questions regarding evaluation principles, activity modifications, appropriate therapeutic exercise progression, return to activity/sport criteria, and indications for physician referral.

Conclusion

This North American based Delphi study presents expert-based consensus on non-operative rehabilitation principles for use in individuals with AD. Establishing guidelines for non-operative management in this population will help reduce practice variation and is the first step in stratifying individuals who would benefit from non-operative management. Future research should focus on patient-reported outcomes and rate of subsequent surgical intervention to determine the success of the guidelines reported in this study.

Published: December 2023

Background

Non-arthritic intra-articular hip pain, caused by various pathologies, leads to impairments in range of motion, strength, balance, and neuromuscular control. Although functional performance tests offer valuable insights in evaluating these patients, no clear consensus exists regarding the optimal tests for this patient population.

Purpose

This study aimed to establish expert consensus on the application and selection of functional performance tests in individuals presenting with non-arthritic intra-articular hip pain.

Study Design

A modified Delphi technique was used with fourteen physical therapy experts, all members of the International Society for Hip Arthroscopy (ISHA). The panelists participated in three rounds of questions and related discussions to reach full consensus on the application and selection of functional performance tests.

Results

The panel agreed that functional performance tests should be utilized at initial evaluation, re-evaluations, and discharge, as well as criterion for assessing readiness for returning to sports. Tests should be as part of a multimodal assessment of neuromuscular control, strength, range of motion, and balance, applied in a graded fashion depending on the patient’s characteristics. Clinicians should select functional performance tests with objective scoring criteria and prioritize the use of tests with supporting psychometric evidence. A list of recommended functional performance tests with varying intensity levels is provided. Low-intensity functional performance tests encompass controlled speed in a single plane with no impact. Medium-intensity functional performance tests involve controlled speed in multiple planes with low impact. High-intensity functional performance tests include higher speeds in multiple planes with higher impact and agility requirements. Sport-specific movement tests should mimic the patient’s particular activity or sport.

Conclusion

This international consensus statement provides recommendations for clinicians regarding selection and utilization of functional performance tests for those with non-arthritic intra-articular hip pain. These recommendations will encourage greater consistency and standardization among clinicians during a physical therapy assessment.
Safety Considerations When Dry Needling the Multifidi in the Thoracolumbar Region: A Cadaveric Study
Authors: Williams Christi L. , Falyar Christian R. , McConnell Ryan C. , Lindsley Stacey
Published: December 2023

Background

Dry needling the lumbar multifidi is a technique used by physical therapists to effectively treat low back pain. While studies have examined the safety considerations in the upper lumbar spine related to the kidneys and lungs, none have investigated the possibility of entering the spinal canal in this region.

Purpose

The purpose of this cadaveric ultrasound-guided dry needling exploration was to determine if a dry needle can penetrate the ligamentum flavum at the T12/L1 interspace and enter the spinal canal using a paramedian approach in a fresh-frozen, lightly fixed cadaver in the prone position.

Study Design

Cadaveric study.

Methods

The procedure was performed on a cadaver in the prone position. The needle was advanced under ultrasound guidance to determine if a 0.30 x 50 mm dry needle inserted 1.0 cm lateral to the spinous process of T12 and directed medially at a 22-degree angle could penetrate the ligamentum flavum and enter the spinal canal.

Results

As determined via ultrasound, a dry needle can penetrate the ligamentum flavum and enter the spinal canal at the thoracolumbar junction using this technique.

Conclusion

This interprofessional collaboration demonstrates that a dry needle can penetrate the ligamentum flavum to enter the spinal canal at T12/L1 using a documented technique for dry needling the multifidus. A thorough understanding of human anatomy along with the incorporation of available technology, such as ultrasound, may decrease the risk of adverse events when dry needling the multifidi at the thoracolumbar junction.

The Implementation of Problem-Based Learning Model to Develop Students' Problem-Solving Abilities in Hybrid Mathematics Learning
Authors: Sianturi Evi Yunita , Dirgantoro Kurnia Putri Sepdikasari
Published: December 2023

Based on the results of observations made and supported by previous research, it can be seen that the problem-solving ability of students still tends to be low. It can be seen that when students are presented with problem-solving problems, students are resistant and in the end unable to do the problem. Even though mathematical problem solving problems can support students' problem-solving abilities. Problem-solving skills are important as basic mathematical competencies and as provisions for everyday life. The purpose of writing this paper is to analyze the application of the PBL model in developing students' problem-solving skills in mathematics learning in a hybrid context. The subject of this study was a grade VII student at a private school in Bogor. The study used descriptive qualitative methods. The instruments used in this study include learning observation sheets, problem-solving tests, student observation sheets, and teaching reflections. The data obtained from the instrument is then processed in a simple descriptive manner, and the results are analyzed qualitatively. The results showed that the application of the PBL model was able to develop the problem-solving ability of grade VII students in mathematics learning. The PBL model is able to equip students to face the challenges of daily life by developing problem-solving skills. Therefore, the suggestion presented to the next researcher is to increase the number of meetings in applying the PBL model to gain a better conceptual understanding for students. Meanwhile, the advice addressed to teachers is to vary the problem solving, one of which is by giving group projects.

At this time the power plant still uses a lot of coal fuel, so it is necessary to look for alternative energy, one of which is wind energy. Wind turbines are devices that can convert kinetic energy in the wind into mechanical energy which is then converted into electrical energy through a generator. The analysis method in this research uses Computational Fluid Dynamics (CFD), Qblade, and experimental validation testing using a wind tunnel. The simulated airfoil types consist of 3 types, namely, NACA 4412, NACA 4415, and FX-60 100 (126). The simulation results show that, the most optimal airfoil is NACA 4412 with an angle of attack of 25° and a wind speed of 8 m/s can produce a torque of 3.55503 Nm, a pressure of 45 Pa, a tangential velocity of 55.495 m/s, and a rotational speed of 529. 94 rpm, while the smallest simulation results are on the FX-60 100 (126) airfoil with an angle of attack of 15° and the same wind speed of 8m/s can produce a torque of 1.60390 Nm, a pressure of 40 Pa, a tangential velocity of 9.06592 m/s, and a rotational speed of 108.2164 rpm. The results of experimental testing of wind turbines where the wind turbine used uses the geometry of NACA 4412 show that an angle of attack of 25 ° and a wind speed of 8m / s produces a large electrical power and rpm with a value of 7.98 Watt and 482.2 rpm respectively

A narração é uma das formas discursivas privilegiadas de significação da experiência, principalmente quando algo inesperado acontece na vida do sujeito e rompe com o seu cotidiano. Partindo do princípio da inevitável articulação entre composição narrativa e transmissão da experiência, defende-se que a narração se torna um dispositivo metodológico e analítico que permite ao sujeito a construção de uma história de si e o desencadeamento de um processo formativo experiencial que se dá em ato. Nessa direção, a fim de demonstrar as premissas, recorreu-se a um estudo com mulheres vítimas de queimaduras de terceiro grau. As narrativas configuradas pelas participantes no enlace com o sujeito pesquisador, tendo a vivência dolorosa como marcador temporal, propiciaram (re)configurações de si em que as marcas corporais decorrentes da queimadura foram incorporadas às suas trajetórias de vida, pois foi possível colocar em palavras o vivido e refletir sobre ele. Dessa forma, conclui-se que a construção de espaços investigativos que propiciem a composição narrativa é essencial para a elaboração de uma vivência traumática a partir do compartilhamento da experiência com o sujeito pesquisador, se tornando assim fonte de aprendizados mútuos.

The pandemic of COVID-19 had a profound impact on the lives of families worldwide, including Muslim families in Indonesia. This study analyzes the resilience of multidimensional Muslim families in Indonesia during the COVID-19 pandemic. It has also been linked to family resilience in preventing divorce, which has reportedly increased during the COVID-19 pandemic. This study uses a qualitative approach. Observation techniques and in-depth interviews are conducted to obtain primary data. There are 25 interviewees. The findings indicate that three dimensions, namely the individual, family, and community dimensions, influence the resilience of multidimensional Muslim families during the COVID-19 pandemic. There is a positive causality relationship between the three interconnected dimensions. The findings suggest that all three can be used to prevent divorce by increasing resilience in these three dimensions. The analysis also reveals a spike in domestic violence, which is the cause of divorce during the COVID-19 pandemic. Domestic violence affects not only wives but also husbands.
