Effects of Bolted-Joint Parameters on Axial Tension after Hydraulic Tightening
Authors: Tanno Yohei
Published: August 2023

The axial tension remaining in a bolt after the hydraulic tightening is less than the initial tension from the hydraulic load, and the ratio of the residual tension to the initial tension, an effective tensile coefficient, is the most critical factor to securely tighten a pressure vessel. In this study, an analysis model simulating the hydraulic joint processes by using a finite element model was developed to clarify the effects of various joint parameters on the effective tensile coefficient. The analysis model could estimate the effective tensile coefficient within a 5% error compared to the hydraulic tightening experimental results. The simulated results of the analysis model showed that the effective tensile coefficient changed largely depending on the thickness and the surface pressure of the flange, and that the coefficient hardly changed by the height of the nut and the friction coefficient at the bearing surface.

Published: August 2023

The paper deals with research on a hybrid technique of coating by Electrical Discharge Deposition (EDD) which has the advantage of lower costs than the other similar methods. This is due to the possibility of using a usual electrical discharge machine, with common tooling, aided by electromagnetic coils that increase the precision and the quality of deposed layers. Some metallic materials like W, Al, Ni, and Ti of high purity are used for EDD, which could be taken from available wires providers. Numerical simulation of the EDD process, using the metals mentioned above was achieved in Comsol Multiphysics. Two connected modules (physics) were used: Magnetic Fields that produced the magnetic force that actuated each of these four categories of ions and Charged Particle Tracing that highlighted the distribution of particles on different cut planes – Poincare maps. Based on these results provided by numerical simulation, it was possible to evaluate the ions behavior, in comparison to electrons, during EDD that is influenced by their atomic mass and the charge number.

The relationship between substance characteristic temperatures: autoignition, melting, flash, boiling is demonstrated and analyzed. Based on the oscillatory and step changes presence, a conclusion was made about the supramolecular structures presence and periodicity in the n-alkanes homologous series. A method for modeling equivalent lengths of peroxide supramolecular structures for predicting the explosion and fire hazard parameters of n-alkanes is proposed. An approximation dependence was developed for predicting autoignition temperatures tai of n-alkanes. It is shown that stoichiometric concentrations of the various supramolecular peroxide structures formation accord to different flammability and explosion limits. A correlation between tai and Anti-Knock Index (AKI) was established. An approximation dependence was developed for predicting n-alkanes AKI. The detonation propensity index КD was introduced based on cluster supramolecular structures modeling and melting temperatures. It is shown that КD indicator correlates with the n-alkanes AKI and with the explosives detonation velocity. The possibility of taking into account during calculations the supramolecular structures presence at the combustion stage confirms their existence.

Authors: Ghori Abdullah , Narendar Saggam , Dubey Yogita
Published: August 2023

One of the most complex issues that govern the design of a hypersonic vehicle is aerodynamic heating which is much more severe for an air-breathing vehicle as it operates within the atmosphere for longer durations. Due to the detrimental impact of aerodynamic heating on the vehicle structure, it is imperative to develop a robust thermal protection system that can protect the vehicle from high temperatures. However, the development of sophisticated TPS for slender components is impractical and, therefore, requires a hot structure system that can operate at substantial aerothermal loads. The aim of this study is to predict the impact of aero-heating on a UHTCC-based hot structure system of a hypersonic cruise vehicle through uncoupled thermo-structural analysis of the control surface. Validation of numerical methods implemented is done through literature comparison and grid independency tests.

Published: August 2023

Composite materials are widely used in various industries. Both ordinary household items and specialized equipment used, in particular, in emergency and rescue formations, are made from them. Each equipment has a different level of reliability. One of the types of such equipment with the lowest level of reliability is fire hoses. Fire hoses work under different internal working pressures, and depending on this indicator, during their manufacture, such materials are chosen that are able to withstand it. High-pressure fire hoses are a separate type of fire hoses. In order to ensure the necessary strength of the material, it includes an internal reinforcing layer, which is a weaving of textile threads or metal wire. The composite structure of the material greatly complicates the process of checking the technical condition of high-pressure fire hoses, which may have hidden defects. These defects can cause their destruction during operation and lead to non-fulfillment of the tasks assigned by units of emergency and rescue formations. Therefore, the study of changes in the properties of the composite material from which high-pressure fire hoses are made due to the influence of various factors on it is relevant.

Published: August 2023

Alginate impression material is a material that is commonly used to print dentures. This material is made from alginate. The properties of this material are rubbery, elastic, and not easily deformed so it can be applied as a bolus. This study aims to determine the tissue equivalence of this material by looking at aspects of the effective atomic number and radiation mass attenuation coefficient. To determine the effective atomic number, we used the EDX results from the SEM machine and input the concentration data of each element from alginate gel with 20% water content into the Autozeff software. The radiation mass attenuation coefficient is simulated by calculations involving each element’s concentration, then confirmed by CT-Number obtained from CT-Scan images. We obtained an effective atomic number and mass attenuation coefficient from the calculation results, which are described as a function of photon energy. Based on the results obtained, it can be concluded that the bolus made from alginate impression material is equivalent to soft tissue and breast tissue.

Published: August 2023

Overproduction of jackfruit (Artocarpus heterophyllus) in harvesting seasons and its short post-harvest shelf life make it an underutilized fruit species. The present study was conducted to analyze the feasibility of preparing processed jackfruit products to enhance utilization and reduce wastage. Jackfruit bulbs were cut into 4.5 cm ± 0.5 cm in length and 0.5 cm ± 0.3 cm in width pieces. The two-factor factorial technique was used as the experimental design when developing the products. As factors, the freezing operation and dipping treatment were considered. Hot water extracts of A. heterophyllus leaves and Trachyspermum ammi leaves were used as two dipping treatments and sensory evaluation tests were carried out to determine which dipping treatment is better. T. ammi dipping treatment had better sensory acceptance, and hence continued as the selected dipping method. The effect of freezing (-18 °C for 12 h), pre-cooking time, and rehydration on cooking time was also investigated. Frozen and non-dipped jackfruit bulb pieces had the highest sensory acceptance, hence its proximate composition, DPPH, total phenolic acid, and colourimetric values were determined. Moisture, ash, fat, crude protein and carbohydrate content of the frozen non-dipped jackfruit bulbs were 8.08 ± 0.28 %, 0.88 ± 0.01 %, 0.31 ± 0.03 %, 3.93 ± 0.06 %, 81.09 ± 0.54 % respectively. The colourimetric values (L*, a*, and b*) of the frozen non-dipped jackfruit bulbs were 79.40 ± 0.61, 1.87 ± 0.35, 25.43 ± 1.33, 25.50 ± 1.35 respectively. The results revealed that the freezing operation significantly (P<0.05) reduce the cooking time of jackfruit bulbs. Based on the sensory evaluation results, jackfruit bulbs that were frozen without dipping the T. ammi leaf extract were identified as having the best sensory acceptability. The final processed product possesses a good nutritional profile concerning the ash, fat, crude protein, carbohydrate, mineral content, DPPH and total phenolic acid content.

Authors: Kim Yoonjoo , Hyon YunKyong , Woo Seong-Dae , Lee Sunju , Lee Song-I , Ha Taeyoung , Chung Chaeuk
Published: August 2023

The stethoscope has long been used for the examination of patients, but the importance of auscultation has declined due to its several limitations and the development of other diagnostic tools. However, auscultation is still recognized as a primary diagnostic device because it is non-invasive and provides valuable information in real-time. To supplement the limitations of existing stethoscopes, digital stethoscopes with machine learning (ML) algorithms have been developed. Thus, now we can record and share respiratory sounds and artificial intelligence (AI)-assisted auscultation using ML algorithms distinguishes the type of sounds. Recently, the demands for remote care and non-face-to-face treatment diseases requiring isolation such as coronavirus disease 2019 (COVID-19) infection increased. To address these problems, wireless and wearable stethoscopes are being developed with the advances in battery technology and integrated sensors. This review provides the history of the stethoscope and classification of respiratory sounds, describes ML algorithms, and introduces new auscultation methods based on AI-assisted analysis and wireless or wearable stethoscopes.

The notions of mentoring and motherhood from a practical theological approach: Biblical examples and viewpoints
Authors: Freeks Prof Fazel Ebrihiam
Published: August 2023

This paper investigates the importance of gleaning suitable information from the Old and the New Testaments to explore the concepts of ‘mentoring’ and ‘motherhood/or womanhood’. The paper also aims to determine the possibility to employ narratives about women as mentor figures in the Bible. An important issue to consider in the context of this paper is how women/mothers lived as role models for others during biblical times in patriarchal societies. Significantly, God established "right and loving" relationships with women throughout history. God has a special relationship with mothers, and He desires that all women develop caring relationships in order to guide and disciple other women. God assigns both parents the duty of teaching their children about His Word and commandments in Deuteronomy 6:7. Parents have a duty to instil in their children the knowledge of God's rules through instruction and discipline, as stated in Exodus 10:2. The teaching role of parents and grandparents is also confirmed in Joel 1:3. Children in this teaching function are guided or led to comprehend who they are in God. In addition, Luke 8:20-23 makes it clear that women accompanied Jesus. This Scripture comments on the essence of complimenting mothers for listening to God's Word and emphasising the family bond and the value of family. Also, in Psalms 127:3, and 139:13, motherhood is ordained and a blessing from God to families and society. Throughout the Bible, the notion of motherhood is described as a unique and important calling. In essence and summary, while both parents share an equal responsibility for teaching and disciplining their children, mothers have a greater task because of the many responsibilities they carry in life.

Most of large and successful companies are derived from family businesses that grow successfully. This business success will only happen if the family-owned business is able to create appropriate company structure and apply good management principles so that the company will develop and survive from one generation to another. A common problem found in family businesses is internal conflict in which the family member has his own interest that could interrupt the business. The differences in opinion and self-interested factors are common things in family business. Another problem that a family business should deal with is external factors. Competitive companies, politics, government regulation are some issues which are difficult to face. Those problems could give impact to the family-owned business. This study was aimed at finding out the problem solutions of family business by analyzing the relationship between family-owned business and its success in SMEs. The research method used was quantitative by using causal design. The primary data was taken from 30 respondents who are the owners of family businesses in SMEs. The technique of data analysis used was simple linear regression in SPSS software version 26. The result of this study confirmed that there was a relationship between family-owned business and its success in SMEs. The roles of family members and good management are the success keys in family businesses and SMEs. This study is beneficial to develop family small business in forms of applied theory that the business ownership has relationship and is able to give impacts towards the business successes.

Authors:   Universitas Islam Negeri Sunan Gunung Djati Bandung, Indonesia, Gojali Dudang
Published: August 2023

Ownership is an important microeconomic theory position in Islamic and capitalist economic systems. The discussion of ownership is not only related to financial aspects but also social and political aspects. Islam is a way of life and a universal religion because it includes all aspects of life related to economic, social, political, and cultural factors. This article aims to analysis the concept of ownership in Islam, the classification of ownership in Islam, and the fiqh rules that form the basis of ownership in Islam. This research uses a descriptive qualitative approach. The primary and secondary data used are books and journals. The concept of ownership in Islamic economics helps eliminate injustice in controlling one's property by individuals, the general public, and the state so that each group can utilize and own wealth fairly and evenly so that Islamic economics can solve the current economic crisis. Classification of ownership in Islam includes three forms, namely: 1) Private ownership (al-milkiyyat al-fardiyyah), 2) Public ownership (al-milkiyyat al-ammah), 3) State ownership (al-milkiyyat al-daulah). Each holding has a foundation.

Wayang Beber is one of Indonesia's cultural legacies. Wayang Beber, once a performance used for rituals, village cleansing, healing the sick, and special occasions in Java, has faced various setbacks in terms of presentation and has garnered less interest from certain segments of society. Data collection involved visiting contemporary Wayang Beber artists, conducting in-depth interviews, and observing contemporary Wayang Beber performances. The process involved summarizing and selecting key points, documenting, and focusing on important aspects of contemporary Wayang Beber performances in the modern era. Contemporary Wayang Beber revitalizes the traditional art form by reintroducing it through performing arts, incorporating dance, and collaborating with artists from Japan. The performances are simplified, shorter, and more entertaining, use modern lighting, feature new characters, and adapt stories that address current popular issues while retaining classic narratives. This research is significant as Wayang Beber is a cultural heritage that deserves to be reintroduced to the wider public. By doing so, the decline of Wayang Beber's performance can be prevented, ensuring its longevity and growth.

Published: August 2023

The scope of the current study is to determine the challenges of employees in between work-life and personal life balance. Organizations should prioritize and maintain employees’ work-life balance. Work-life balance refers to the equilibrium between an employee's work responsibilities and their personal life, including family, hobbies, and personal well-being. When employees have a healthy work-life balance, they experience less stress and improve their working skills to achieve the targets, and this well-being leads to improved mental and physical health as well as work productivity. This descriptive research approach surveyed by 67 responses as simple random technique, provides a significant result toward organizations that they should maintain employee’s work-life balance. The research finds that organizations that prioritize work-life balance are more likely to attract and retain top talent. By the managing time, regular assessment and adjustment in work-life balance initiatives, organizations can enhance their employer brand and improve employee retention rates. Work-life balance allows employees to have time for personal pursuits and interests outside of work which can contribute to their creativity and innovation. When employees have a healthy work-life balance, they are more likely to have positive relationships with their colleagues and supervisors. Improved relationships can lead to better teamwork, collaboration, and a more positive work environment.

Khilafat Movement was started in British India immediately after the end of the First World War (1914-18). Maulana Muhammad Ali Jauhar and Maulana Shaukat Ali, the graduates of Sir Syed Muslim Anglo-Oriental (MAO) College, were its founding leaders. It got mass recognition when the Indian National Congress, under the leadership of Mohandas Karamchand Gandhi, joined the Movement. It also provided a solid platform for propagating his famous political philosophy of non-violence. Unfortunately, when the Movement was at its peak, Gandhi separated himself from it based on his non-violence approach. This study is focused on the impacts of the Khilafat Movement on Indian politics during the period 1920-40. The descriptive and exploratory method was adopted to analyze the results of the Movement. Religious movements like Shuddhi, Sanghatan and Tablighi Movement, and the religious political party, Jamiat Ulama-e-Hind, were founded during and after the Movement. The Jamia Millia Islamia was founded against the Muslim University Ali Garh. The Rashtriya Swayamsevak Sangh (RSS), initially a Hindu reformist movement, which later became a violent extremist group, was founded in 1925. Hindu-Muslim riots started after this Movement at regular intervals, which never ended till the partition of India in 1947.

Greenhouse Gases (GHGs) and climate-altering air pollutants are damaging the ecosystem of Earth. Hence, reducing gaseous emissions and air pollutants would help mitigate global warming and improve the low-carbon economy. Therefore, in this study, remote sensing datasets from the Goddard Earth Observing System, Atmospheric Infrared Sounder and Modern-Era Retrospective analysis for Research and Applications Version 2 are carried out to examine the seasonal trends of Carbon dioxide (CO2), Methane (CH4), Ozone (O3) and Aerosol Optical Depth (AOD) from 2016 to 2021 over brick kiln zones in Punjab, Pakistan. In this research, 2016 has been taken as the base year to compare the trends of GHGs and AOD in Punjab. Results of the study revealed that the highest concentration of AOD was exhibited in the winter seasons over Purple, Red and Orange Zones of brick kilns. Moreover, the highest extent of CO2, CH4 and AOD was observed in 2017. At the same time, O3 magnitude was evaluated as high during summer seasons which may be attributed to high temperature that leads to elevated formation of O3. Therefore, there is a dire need to undertake Nature Based Solutions (NBS) in the policymaking for the environmental development of Pakistan.
Análise da integração da modelagem algorítmico-paramétrica com a Modelagem da Informação da Construção (BIM)
Authors:   , Iasbik Marina Pires
Published: August 2023

Esta pesquisa investiga a adaptabilidade do processo de projeto em BIM (Building Information Modeling) às novas perspectivas do design computacional, com ênfase na integração das lógicas de Modelagem da Informação da Construção (BIM) com a modelagem algorítmico-paramétrica, aqui representada pela modelagem desenvolvida através do Grasshopper. Sabe-se que, somadas, essas estratégias de projeto representam a possibilidade de uma grande liberdade e variabilidade na descrição das representações formais, em um modelo coordenado de todos os aspectos de um edifício. No entanto, constatou-se uma incapacidade de importar ou integrar facilmente em BIM elementos geométricos ou conjuntos gerados no Grasshopper. Visando buscar alternativas que facilitassem na interoperabilidade BIMxGrasshopper, foram realizados testes a partir de diferentes software, plataformas e plugins atuais relacionados à transmissão de dados em BIM. Foram escolhidos dois plugins visando a conexão do Grasshopper ao Archicad e ao Revit: o Archicad Live Connection e o Rhino Inside Revit, respectivamente. Comparando-se os fluxos de trabalho relacionados a cada combinação de ferramentas, levantaram-se os pontos positivos e negativos de cada um e foram delimitadas as situações em que cada fluxo é mais adequado. Os testes demonstraram que ainda existem barreiras na integração do BIM com aplicativos de modelagem algorítmico-paramétrica, sobretudo devido às diferenças em suas lógicas de funcionamento, por serem ferramentas de empresas proprietárias distintas. No entanto, algumas soluções foram encontradas para facilitar o processo de projeto, alcançando-se maior interoperabilidade entre software diferentes, e não deixando que as limitações impostas por algumas barreiras, que naturalmente surgiram com os novos processos de projeto a partir do uso do BIM, limitassem o uso de software específicos para cada necessidade de projeto.

Postpartum hemorrhage (PPH) is the primary cause of maternal mortality and morbidity worldwide: in fact, about a quarter of deaths that occur during pregnancy, childbirth or the puerperium are caused by postpartum hemorrhage. There are many causes of postpartum hemorrhage, the most important are: uterine atony, lacerations of the cervix and/or perineum, retention of placental material, coagulation problems, uterine inversion, uterine rupture. This causes of PPH are represented by the ‘4Ts’ formula: tone, tissue, trauma, thrombin. An important role is played by prevention: identification of risk factors, prophylaxis with oxytocin at the time of delivery, early treatment. The first important thing is the quantification of blood loss because the clinical signs are often blurred and due to frank anemia resulting in tachycardia, small and frequent pulse, hypotension, sweating, paleness. As previously mentioned, it is important to act early in the case of PPH through maintenance of velamina and targeted therapies that differ according to the cause of PPH (the 4T algorithm is useful). Early intervention reduces the need for blood transfusions and reduces the incidence of serious complications such as DIC. However, the management of postpartum hemorrhage is not limited to the postpartum phase, but the patient must be monitored in the puerperium, a phase in which the thromboembolic risk is increased. The couple must also be informed of the risk of PPH in future pregnancies. PPH represents a serious risk for the patient and requires multidisciplinary input and proper preparation of the team working in the delivery room.
Child marriages

Child marriages are major public health issues in the developing world. It is defined as marriage before the age of 18 years. According to UNFPA (United Nations Fund for Population), in developing world, 36 percent of girls are married before reaching the age of 18 years, and 10 percent of girls in these countries are married before the age of 15 years.1 Globally, it is estimated that 10 million pregnancies occur in adolescent girls, and 90% of these occur in developing countries.2 The burden is mainly borne by the Sub Saharan Africa and South Asian countries.3 Except in Nepal, where legal age of marriage is 20 years, the legal age in India, Bangladesh and Srilanka is 18 years. In Pakistan, except for the Sindh province where legal age of marriage is 18 years, the rest of the provinces have legal age of 16 years for contracting marriage. Hence there is increased prevalence of child marriage in Baluchistan and Khyber Pakhtunkhwa provinces.4 It is observed that this legal cover is mainly seen on papers, and reality is far different in the actual world. Child marriages not only take away the joys of childhood, it also brings with it the burden of social, psychological and reproductive harms. It not only affects the female child, but also has its effects on the male child. The burden of raising and supporting a family at a younger age exerts extra mental and psychological trauma, among boys. This in turn increases the incidence of domestic violence among the couples. It is a well-known fact that child marriages are more common in low- income household, rural areas, and at times are contracted in order to settle family disputes. In rural areas these child marriages are seen as a stop gap arrangement for premarital sex, unwanted pregnancies and sexual assault. These adolescent girls are married to elderly men, invoking mental disparity and psychological trauma. There is also increased prevalence of domestic violence and wife beating in this age group. Vertical transmission of this attitude has also been observed in studies. This basic violation of human rights is transferred from mothers to daughters as normal behaviours.5

From Newtonian concepts to a quantum understanding: The evolution of endocrinology and metabolism
Authors: Sanjay Kalra  , Saurabh Arora  , Nitin Kapoor
Published: August 2023

Conventional endocrinology is based upon linear or Newtonian feedback mechanisms. This framework helps in learning and sharing science in a lucid and simple manner, just as Newton’s Laws clarified our understanding of physics. Modern endocrinology and metabolism are more confusing, as exemplified by the multifarious etiopathogenic factors that continue to be unearthed for various diseases, such as obesity and diabetes. These diseases tend to follow a model similar to that of quantum physics. We propose a Quantum theory of baro-mechanics to help understand the complexity that surrounds metabolic disease, especially obesity. Hopefully, this insight will help mitigate the frustration that one encounters while managing these conditions.

Published: August 2023

Spinal subependymoma (SSE) is a rare intramedullary, benign tumour. Surgical excision is the preferred approach. However, the interwoven pattern of neural tissue within the tumour dictates the extent of resection. Where gross total resection is linked with possible neurological deficits, subtotal resection or close observation may support better functional outcomes. The evidence for the management of SSE is based mostly on case reports. Herein, we review the existing literature regarding treatment options and clinical outcomes of spinal subependymoma.

Hepatic Haemangioma is the most common benign liver tumour. There are two types of haemangiomas: capillary haemangioma and cavernous haemangiomas. The term “giant haemangioma” is reserved for lesions larger than 5 cm. Given the abundance of vascular structures around the liver, SPECT/CT hybrid imaging with 99mTc labelled Red Blood Cells (RBCs) constitutes an excellent modality for localization and characterization of hepatic haemangiomas.
