FCAW welding is an automated welding process that employs a wire roll electrode to melt metal, using flux or powder within the electrode's core for protection. A common issue with FCAW welding is the occurrence of angular distortion and alterations in the length and width dimensions, particularly in thin plate iron materials, due to residual stresses from the welding process. This research aims to assess the impact of static thermal tensioning, preheating, and their combination on angular distortion in SS400 steel corner joints during FCAW welding, considering heat input during welding. True experimental research methodology was employed, with variations in preheating temperatures of 200°C, 250°C, 300°C, static thermal tensioning at 150°C, 200°C, 250°C, transient thermal tensioning at 150°C, 200°C, 250°C, and a reference method with no treatment to determine the welding approach that minimizes angular distortion. The material used was 3mm thick SS400 steel. Data analysis was performed using Minitab 18 software and the One-Way Anova method. The research results indicate a significant influence of static thermal tensioning, preheating, and their combination on angular distortion. The optimal welding methods identified are preheating-static thermal tensioning at 89°55', preheating-transient thermal tensioning at 89°50', static thermal tensioning at 150°C at 89°45', transient thermal tensioning at 150°C at 89°40', and preheating at 200°C at 89°35'.

Solar panels are used to convert solar energy into electrical energy. In this study it was applied to electric vehicles which have a very large potential for being constrained by shadows. In fast varying partial shading conditions, the position of the maximum power point is divided into two, namely GMPP and LMPP. This condition makes the MPPT process stuck in LMPP. Therefore, this research proposes the application of Serval Optimization Algorithm (SOA) in MPPT. This method refers to the natural behavior of the serval in nature. The fundamental inspiration of SOA is the serval hunting strategy in two stages of exploration and exploitation. The SOA is implemented in MPPT to change (duty cycle) so that it gets the best value and produces maximum solar panel output power. This SOA method was chosen to complete the partial shading conditions so that MPPT can optimally reach GMPP without going through LMPP. The solar panels used in this system are 2 units with specifications of 25 Wp with a 24V battery load and a 120W BLDC Motor compact in Electric Vehicle - Two Wheeler Scooter. MPPT SOA was tested in a simulation using PSIM and actual Software in 6 variations of normal and partial shading conditions. In the Simulation Test of Partial Shading Conditions, an average accuracy of 99.958% and an average tracking time of 0.492 seconds were obtained. SOA has a higher accuracy than PSO and GWO, which is 99.95%. And it has a faster tracking time of 0.55 seconds. In the SOC Integration Test, the SOA Method obtained an error value of 6.48% better than the GWO Method. On the Road Test with 6 condition, it can slow down the value of the decrease in battery capacity by 16.24%. The application of Single Source on the PV-MPPT-Converter can be implemented with an efficiency value of 76.86%. In previous research where SOA is a new method in Optimizing Problem Solving which has quite good accuracy performance, and in this research it can be implemented in Solar PV Optimization to track MPPT electric vehicles with varied and fluctuating partial shading conditions.

Fiber-reinforced composites can be classified into two parts, namely short fiber composites and long fiber composites. Long fibers are generally stronger than short fibers. Long fiber (continuous fiber) is more efficient in laying than short fiber but short fiber is easier to lay than long fiber. Fiber length affects the processability of the fiber composite. Judging from the theory, long fibers can transfer the load and stress from the stress point to the other fiber. In this research, we simulated the effects of volume fraction and fiber orientation in glass fiber-reinforced polyester composites on bending strength to examine the effect of each parameter on the mechanical properties of glass fiber composites. The mechanical properties of the composite were tested using the three-point bending and tensile testing methods. The study expects to find variations in mechanical properties with changes in the glass fiber volume fraction and fiber orientation. In this study, it is planned to function in a relevant environment, the components in this study must be able to operate properly and have been well integrated with prototype manufacturing that has been tested as a test tool function. Notably, the pinnacle of the bending test, measuring 170.41 MPa, was achieved at the specific combination of a 0.5 Fiber Volume Fraction and the 0-90o fiber orientation.

Authors:   Universitas Katolik Prahyangan, Adhiyasa Prima
Published: August 2024

The substantial expansion of the global economy and the extensive urbanization witnessed in recent decades have rendered bridge infrastructure as a vital component of transportation systems. Conducting structural damage detection is a vital strategy to prevent structural failures and avert bridge collapse. One popular approach for detecting damage is to use mode shapes as characteristics in structural dynamics analysis. In this study, the identification of the mode shapes in the damaged condition will utilize the Modal Assurance Criterion (MAC), while the location of the damage within the simulation will be identified using the Mode Shape Data Base Indicator (MSDBI). The study was carried out with the help of a finite element model using Midas Civil software with a case study of a steel frame bridge. Referring to the report studied, damage identification focused on damage caused by loose bolts. The results of the analysis show that the MAC analysis has consistent values on mode shapes in each damage simulation with the mode shapes produced by the healthy condition model. Meanwhile, damage location is detected by the MSDBI index value in each damage simulation. It can be seen that the MSDBI index changes according to the location of the damage.

Published: August 2024

COVID and HIV are both common diseases, with COVID affecting an estimated 775 million and HIV affecting 39 million people worldwide. Guillain-Barre is a rare but feared complication of immune stimulation in which the body generates autoantibodies against gangliosides, found in the nodes of Ranvier, in the myelin, and in the ganglia; causing ascending paralysis. A mid-30s man with HIV maintained on Genvoya presented to the Jefferson Health New Jersey Early Intervention Program clinic with fatigue, fever, cough, and congestion and tested positive for SARS-CoV-2 on the following day. Two weeks later, he presented to the emergency department complaining of numbness, paresthesias, weakness, and abnormal gait of the left lower extremity. Imaging demonstrated vertebral artery stenosis and foraminal stenosis, but no acute cause of nerve impingement. Other meningitis and encephalitis testing was negative, but CSF contained red blood cells. Numbness continued to ascend to the torso and ganglioside testing was ordered while a 5-day course of intravenous immunoglobulin was started. His symptoms began improving one week after finishing treatment and EMG was normal 9 weeks later. At his last visit, he endorsed residual altered sensation in the perirectal area and left thigh, but motor function was intact. Close support from his husband and community was vital in early identification of key symptoms and entry to treatment. Guillain-Barre should be considered in patients with fulminant symptoms even in the setting of HIV- and HAART-induced peripheral neuropathy or spinal stenosis.
Pros, Cons, and the Barriers to Implementing a Universal Healthcare System in the United States
Authors: Shah Arpun
Published: August 2024

Background: The United States has the most expensive healthcare system in the world. Despite that, it also has worse health outcomes than that of several other countries. The United States is also the only wealthy/developed country without universal healthcare. Universal healthcare, also known as a single-payer healthcare system, refers to the concept that the government finances and governs healthcare for most, if not all residents of the country. The United States currently has a multi-payer system, which means that healthcare is financed through various sources such as the public and private sectors. Purpose: The purpose of this is to investigate the potential benefits and drawbacks of a universal healthcare system as well as identifying some of the potential barriers towards implementing a universal healthcare system in the United States, based on current, peer-reviewed literature. Methods: Peer-reviewed articles relevant to the topic were collected from databases such as PubMed. PRISMA criteria were used to identify relevant publications after applying inclusion and exclusion criteria. Data regarding health outcomes and healthcare expenses among different countries were compared and analyzed to help determine the effectiveness of universal healthcare. Results: Based on the studies, it can be inferred that the United States would significantly benefit from a universal healthcare system as studies show improved health outcomes as well as reduced healthcare expenditure, partially due to an emphasis on primary and preventative care, thus increasing access to overall care. However, there are also a few major barriers such as political lobbying that have prevented a significant overhaul of the current healthcare system in the United States. Conclusion: Universal healthcare would provide many benefits for the United States; however, political considerations pose a significant barrier that will need to be overcome before universal healthcare is implemented. That being said, there has been an increase in support for universal healthcare among Americans, in which small incremental steps can eventually lead the way there.
Morel Lavallee Lesion: A Shear Fascia-nating Soft Tissue Injury
Authors: Su Isaac F. , Espinosa James A. , Lucerna Alan A.
Published: August 2024

Morel-Lavallée lesions (MLLs), first described by their namesake, French physician Victor-Auguste-François Morel-Lavallée, in 1863, represent a distinct category of soft-tissue degloving injuries. These injuries occur when a shearing force disrupts the connection between subcutaneous tissue and fascia, severing lymphatic vessels and capillaries, and leading to an encapsulated collection of lymph, blood, and necrotic fat. Because this space is deep and enclosed, the fluid accumulation cannot easily drain or resolve spontaneously and often an inflammatory capsule develops, further inhibiting resorption. Undiagnosed, patients go on to develop chronic pain, infection, skin necrosis, progressive neurovascular deficits, and, in severe cases, potential loss of limb and even life. For emergency medicine physicians, the implications are significant: Recognizing MLLs when a trauma patient first presents to the ED is crucial to avoiding long-term disability, morbidity, and mortality. We report a classic presentation of a MLL, highlighting how a thorough history, physical, and bedside POCUS allowed the diagnosis to be made after a delayed presentation to the ER, potentially sparing the patient significant morbidity and chronicity.
Opioid Prescription Rates Before and After ALTO Program and Various Factors Affecting Emergency Department Opioid Prescription Rates
Authors: Patel Neel B. , Baird James F.
Published: August 2024

Opioid prescription rates vary between patient population, diagnosis, location, and emergency department characteristics. High prescription rates offer an avenue for potential opioid addiction and overdoses. Alternatives to opioids (ALTO) is a new program already implemented in certain emergency departments to help change opioid prescription rates by introducing new protocols for first line treatments for pain management. With current trends still showing that South Jersey opioids prescription rates are the highest in the state of New Jersey, ALTO was introduced at Inspira Health Network located in South Jersey. This study retrospectively analyzed opioids prescription rates for abdominal pain, renal colic, migraines, and low back pain preintervention and postintervention of ALTO at Woodbury Inspira Emergency Department in order to see the effects of ALTO. Here we report that although overall prescription rates were not significantly changed pre and post intervention, ALTO was effective in significantly reducing opioid prescriptions for migraines. In addition, female patients were significantly prescribed more opioids than male patients and young adults to adults were significantly prescribed more opioids than children, adolescent and elderly. ALTO has shown glimpses in its effectiveness in helping to reduce opioid prescription rates for specific diagnosis. More research still must be done to better understand opioid prescription rates and effectives of ALTO.

Published: August 2024

It is preferable to cast pipe steel on a slab caster with a vertical section, which allows to produce castings with less metal contamination by non-metallic inclusions. The paper considers casting of pipe steel on a single-strand slab caster of curvilinear type with a base radius of 11 m, a vertical section of 2.7 m, with soft compression of the billet. The productivity of the machine significantly depends on the cross-sectional dimensions of the castings and other factors. The paper studies the influence of slab cross-sectional dimensions and parameters of the temperature-rate mode of pipe steel casting on the productivity of a single-strand CCM. For this purpose the array of production data of pipe steel casting of strength class K60 from 105 melts was investigated. In the majority of cases – 89 melts (85% (relative)) were cast billets with cross-sectional dimensions of 350×2600 mm, the rest of the metal had a cross-section of 250×(2250, 2600) mm. The main difference between slabs was in the thickness of billets: 250 and 350 mm. In the work it is established that the hourly productivity of a single-strand slab caster of curvilinear type with a vertical section when casting tubular steel of strength class K60 into slabs of 350×2600 mm cross-section is on average equal to 291.8 t/h. This is 1.2 times higher than when casting slabs of 250×(2250, 2600) mm – 245.8 t/h. As a result of correlation-regression analysis of the data set of 89 melts when casting slabs with the cross-section of 350×2600 mm, statistically significant dependences of the speed of pulling the billets out of the mold and the hourly productivity of the CCM on the superheating of the metal in the intermediate ladle above the liquidus temperature were established. In order to obtain hourly productivity of CCM not less than 290 t/h it is necessary to have average superheating of metal in the intermediate ladle above the liquidsus temperature not more than 28 °С.
Метрологический дефицит в промышленных «больших данных»

Published: August 2024

Широкое распространение киберфизических систем в промышленности, рост использования машинного обучения, искусственного интеллекта, цифровых двойников и другие технологии цифровизации предъявляют высокие требования к качеству собираемых данных, характеризующих объект исследования. Современные вычислительные мощности позволяют получать измерительную информацию со скоростью, недоступной уровню развития прошлых лет. Дефицит вычислительных мощностей приводил к тому, что анализ собираемых данных проводился на основании только лишь
значений величин, без метрологических метаданных (погрешность, принцип измерений, характеристики средств измерений и др.). Прежние подходы строились на той аксиоме, что если средство измерений имеет статус поверенного и допущенного к использованию, то полученные данные имеют
допустимую точность. В настоящее время нет дефицита в вычислительных мощностях и готовых программных решениях для анализа данных и даже не самые крупные предприятия могут проводить анализ данных одновременно и быстро, и точно. Появилась возможность учитывать метрологические метаданные, которым не уделяется должного внимания. По сути, можно говорить о том, что в промышленных «больших данных» имеет место метрологический дефицит, что создаёт риски,
связанные с ошибочными выводами при анализе этих данных. Авторы показывают, как на основании существующей в России материальной и нормативной базы, можно решить проблемы метрологического дефицита в собираемых промышленных «больших данных».

Published: August 2024

In this article, we will provide interpretations regarding fathers naming their sons by name and we will summarize the main points of their statements that have been brought forward so far. The scripture mentions that Adam called his third son by his name, even though it has already been mentioned that Eve called her son by his name. For example, the Ramban claims that the scripture emphasizes that the calling by name is precisely for those who will continue the chain of generations, the Melbim points to the same principle and says that it was appropriate to mention from whom the kingdom of the house of David will come.

The study also explores the significance of these principles for Ukrainian public administration, especially in the context of reforms and integration into international organizations. The research provides insights into how international standards, based on values like human rights and transparency, can influence and improve public administration in post-Soviet states, which often face challenges like centralized control, corruption, and limited public participation.
MEANS AND METHODS OF WARFARE IN THE LIGHT OF RUSSIAN INVASION OF UKRAINE
Authors: Tomljenović Marija
Published: August 2024

Abstract. For Putin to fulfill his vision of national and personal greatness, primarily through Russian aggression against Ukraine, which has absolutely no basis in the legal regulations of international law, nor in other laws and legal acts, the fact is that Russia, and Putin personally are responsible for tens of thousands of deaths in Ukraine. The aim of this paper is to highlight the means and methods of warfare in the Russian-Ukrainian war aimed at the eastern and southern territories of Ukraine, as well as frequent pressure directed at Western society using sabotage and destruction of infrastructure in the West. Putin's indispensable strategy of waging war also includes constant threats about the use of nuclear weapons. Russia's "escalation to de-escalation" strategy of using conventional weapons on the battlefield and changing the course of conventional warfare that threatens Russia's survival allows for the use of tactical nuclear weapons. Considering the thesis presented by the US Department of Defense in 2018, Russia has non-negligible and certain advantages in tactical nuclear forces. According to such a claim, as well as Putin's fiction of a “special military operation”, all under the pretext of preventing Russian progress, the Russian military doctrine that developed the Russian strategy of “escalation to de-escalation” is more precisely called “escalation to victory”. In this sense, Europe must free itself from Russian energy dependence, and NATO needs a huge injection of funds to strengthen it to free Ukraine from Russian aggression and Putin's intensity of doubling the war, instead of slowing it down. Although the author of this paper does not intend to give an outcome about the Russian-Ukrainian war, the author nevertheless dares to point out that this war is not coming to an end, but rather to the end of its beginning.

Abstract. Administration of local taxes is an important aspect of financial decentralization and strengthening of local self-government in Ukraine. This topic examines legal acts regulating the process of setting, calculating, paying and controlling local taxes, as well as analyzes existing problems and prospects for improving legal regulation in this area. The basis of the legal regulation of the administration of local taxes in Ukraine is the Tax Code of Ukraine, the Law of Ukraine "On Local Self-Government in Ukraine", the Budget Code of Ukraine and a number of by-laws that provide detailed administration procedures and mechanisms. The establishment of local taxes is carried out by local councils, which determine tax rates, payment procedures and benefits within the limits set by national legislation. Analysis of current legislation reveals key aspects and problems of legal regulation of this topic. In particular, there is a need to increase the flexibility of local authorities, improve transparency and accountability of the use of tax revenues, simplify administration procedures and reduce the bureaucratic burden on taxpayers. Thus, the legal regulation of local tax administration is a key factor of financial decentralization, which requires constant improvement to ensure a stable and transparent flow of funds to local budgets and strengthening of local self-government.

The NEP 2020 recommends for vibrant University-Industry linkage with an emphasis on exposing students to real-life situations and making them globally competent. Keeping this in view, the UGC has approved the guidelines entitled “A Sustainable and Vibrant University-Industry Linkage System for Indian Universities”. These guidelines will promote research and development through collaborations between universities and industries. Establishing the linkages between university and industry will help to create training and apprenticeship opportunities in the industries, R&D labs and research organizations. The Higher Educational Institutions (HEIs) have been advised by the UGC to initiate necessary measures to research and development by creating R&D clusters at the State or Regional levels through University-Industry (UI) linkages. These guidelines shall promote research and development through collaborations between Universities and Industries. It will also help students to develop skill sets among learners and make them fit for industrial skills through internships, including fields/industry/ on the job skills/vocational training/ life skills to achieve the learning objectives and attain desired outcomes effectively. Establishing the linkages between the university and the academic world will help to create training and apprenticeship opportunities for students in the industries, R&D labs, as well as in research organizations. Keeping all these aspects in view, the UGC approved guidelines for University-Industry linkages enlightens the practicians with regard to Objectives of the scheme; Mechanisms to boost R&D through University-Industry Linkages; University-Industry (UI) linkages for enhancement of student internship and apprenticeship in academic and industrial systems; and sustainability of the proposed UI linkage system. The present article will enlighten all the academicians to establish sustainable and vibrant linkage between Indian universities and industries.
Belonging as a post-secondary inter/national student
Authors: Abdalla Faisal Mohammad Ali
Published: August 2024

International students worldwide increased from two million in 2000 to more than five million in 2017. International students may experience one or more challenges, such as financial issues, language limitations, academic performance, social and cultural differences, discrimination and racism, and identity reconstruction. Many of these challenges affect international students' sense of belonging. The concept of belonging is multi-faceted. We can belong in different contexts, for example, to families, institutions, cultural or ethnic groups, and religions, and we belong at both concrete and abstract levels. As an international student, I used autoethnography to study my sense of belonging as an individual who is also a graduate student.  Autoethnography allows the researcher to relate personal experiences to wider cultural, political, and social meanings and understandings. This enabled me to focus on interpreting my core personal narrative, linking my life and story to international students' lives and stories.
ОРГАНІЗАЦІЙНО-ПЕДАГОГІЧНІ УМОВИ ФОРМУВАННЯ КЛЮЧОВИХ КОМПЕТЕНТНОСТЕЙ УЧНІВ З ОСОБЛИВИМИ ОСВІТНІМИ ПОТРЕБАМИ ЗАСОБАМИ ІНТЕРАКТИВНИХ ТЕХНОЛОГІЙ

У статті визначено й описано організаційно-педагогічні умови формування ключових компетентностей молодших школярів з особливими освітніми потребами засобами інтерактивних технологій в умовах реалізації концепції «Нова українська школа»: організація соціально-комунікативної взаємодії молодших школярів в інклюзивному середовищі Нової української школи; мотивація щодо підвищення активності учнів молодшого шкільного віку з особливими освітніми потребами під час виконання інтерактивних завдань; поетапне формування соціально-мовної ключових компетентностей молодших школярів в інклюзивному середовищі на спеціально організованих заняттях із застосуванням інтерактивних форм роботи; організація інтерактивного середовища у формуванні визначених ключових компетентностей учнів молодшого шкільного віку. Актуалізовано проблему застосування компетентнісного підходу до організації навчання молодших школярів з особливими освітніми потребами, як стратегічного напряму розвитку України на шляху модернізації освіти відповідно до суспільних запитів і викликів. Обґрунтовано, що організація інтерактивного навчання передбачає моделювання життєвих ситуацій, використання рольових ігор, при цьому молодші школярі з особливими освітніми потребами, висловлюючи свою точку зору стосовно тієї чи іншої проблеми, вчаться доказово міркувати, спільно вирішувати питання на основі аналізу обставин і відповідної ситуації. Доведено, що використання інтерактивних технологій на уроках в Новій українській школі урізноманітнює освітній процес, роблячи його привабливим і цікавим, збагачує педагогічне середовище новими враженнями, залучаючи кожного учня до роботи й активізуючи його можливості.
СУЧАСНІ ПІДХОДИ ДО ОБРОБКИ СТАТИСТИЧНОЇ ІНФОРМАЦІЇ В СОЦІАЛЬНІЙ ПЕДАГОГІЦІ

Соціальна педагогіка, головне завдання якої – вивчення закономірностей соціально-культурної адаптації особи, колективів, суспільства з метою гуманізації і гармонізації їх відносин, відрізняється трьома принциповими рисами, а саме: – широким використанням статистичних даних, оскільки вони є основою для виявлення тих чи інших закономірностей; – необхідністю обробки вибірок великого обсягу з метою забезпечення належної надійності статистичних висновків; – аналіз величезних масивів даних спонукає кожного дослідника в галузі соціальної педагогіки до широкого використання статистичних програмних продуктів із метою автоматизації обчислень. Оскільки соціальна педагогіка в Україні є ще досить молодою дисципліною, то цим її особливостям не приділяється належної уваги. До того ж ці її принципові риси ще не цілком усвідомлені фахівцями в галузі соціальної педагогіки. Метою цього дослідження є не тільки розкриття значення кожної із зазначених особливостей соціальної педагогіки, а й насамперед сучасних підходів до обробки статистичної інформації класичних і некласичних обсягів.
