Authors: T.O Al-Qahwaji Tahseen , A.A Al-Jobory Yasir
Published: March 2023

An experimental and numerical study of tube curved flaring process was conducted to investigate the effect of strain hardening characteristic of material on the process using two metals that differ in strain hardening characteristic which are pure copper and brass (70-30) by using curved dies which have curvature ratio () of (6) and (12) and base radius of die (rd=24mm) and () is the radius of curvature. The experimental part was included experiments on specimens with an outer diameter of (39 mm) and a wall thickness of (2 mm). The expansion process was carried out for different expansion ratios that it was reached to about (32%). The results were showed that the strain hardening exponent of pure Copper more than Brass (70-30) and its value reached (0.54) for pure Copper and (0.49) for Brass (70-30).  However, this paper concluded a study of the effect of strain hardening characteristics on the curved flaring process. It was found that the increasing of flaring ratio and relative axial displacement of the die through the specimen are caused increase in the relative forming stress, and its value is significant in expanded tubes with high strain hardening characteristic and it is about (0.77) in Brass and (1.42) in Copper. It also found that a little difference in the deformation of specimens' geometry which means that the deformation is not affected by the strain hardening characteristic and there is no significant difference in strain distribution. The study also included a numerical simulation using the finite element ANSYS program. The results obtained are compared with experimental data and showed good agreement.

Authors: Iwatani Yuta , Asada Hiroyuki , Yeh Chi-An , Taira Kunihiko , Kawai Soshi
Published: March 2023

The self-sustaining mechanisms of shock oscillations in transonic airfoil buffet are studied by wall-resolved large-eddy simulation (LES) and resolvent analysis. The LES successfully reproduces the large-scale shock oscillations over a transonic OAT15A airfoil, and the resolvent analysis using the high-fidelity LES data reveals the input–output relations in the self-sustained shock oscillations. Based on the input–output relations revealed by the resolvent analysis, this study identifies two mechanisms of the self-sustained shock oscillations. The first mechanism is closely tied to the periodic variations of the shock-induced separation height, whereas the second mechanism is related to the pressure dynamics around the shock wave. The mechanisms of the self-sustained shock oscillations identified by the input–output relations are examined in detail along with the high-fidelity LES data to aid the understanding of the feedback formulations in transonic airfoil buffet.
Characteristics of Combined-Cycle Inlet During Mode Transition in Off-Design State

Published: March 2023

Mode transition is essential for the combined-cycle engine inlet. During actual inlet operation, mode transition may occur in the off-design state. An experiment was performed with a generic over/under combined-cycle engine inlet mode to investigate the characteristics of the inlet mode transition in the off-design state. The transition Mach number was set to Mach 3.5 by design, while it was 2.9 during the experiment. Oscillatory flow is obtained during both down- and up-rotation processes of the splitter. Results show that the size and location of the separation bubble vary with the splitter position. The dominant frequency of the flowfield oscillation is always below 200 Hz. Combining the analysis of schlieren and dynamic pressure data, it is found that the main factor affecting the flowfield oscillation features is the self-excited oscillation of the shock train, while the acoustic resonance frequency is also reflected near the unstart point. Comparison of the pressure curves of the two processes shows that the hysteresis interval accounts for 17.8% of the entire rotation time of the splitter and that the hysteresis stems from the presence of the separation bubble on the splitter during the up-rotation of the splitter. The analysis of the unstart and restart points shows that they deviate from the isentropic and Kantrowitz limits, respectively. The new unstart and restart boundaries should consider the combined effect of the separation bubble at the duct entrance, the internal wave system, and the throat Mach number.
Autonomous Vehicle for Asphalt Laying
Authors: Gonzalez Gilberto
Published: March 2023

Autonomous vehicles are constantly being developed and are gaining recognition from many industries to improve workplace safety and efficiency. This project intends to weaken the barrier that prevents the usage of autonomous vehicles in the workplace. To move toward this objective, this project focuses on developing a computer vision system for an autonomous utility vehicle that lays asphalt. The goal of this project is to directly address the issue of the high number of potholes in our driving roads, which create a dangerous and hazardous environment for persons that utilize motorized and non-motorized vehicles on roads. The vehicle’s computer vision system will be executed using a stereo depth camera sensor and will be primarily focused on two factors: detecting and driving toward potholes with high accuracy and avoiding common workplace objects, such as persons, equipment, etc. A deep-learning neural network with custom-trained data of more than 4000 images is currently being utilized to detect a test target with up to 85% confidence; we intend to utilize the same deep-learning model to train data for accurately detecting potholes. The vehicle distinguishes nearby objects by utilizing the depth detection features of the camera. This project has the potential of obtaining several implications. Creating better quality roads, improving workplace safety, and increasing production/efficiency are all results that may flourish through successful execution and implementation of this project.

Authors: Wang Danfeng , Min Shuhui , Lin Xiao , Jiang Guan
Published: March 2023

Background

To investigate the clinical features, pathological features and prognostic factors of cutaneous extranodal natural killer/T-cell lymphoma (CENKTL).

Methods

A total of 20 cases with CENKTL from February 2013 to November 2021 were analysed retrospectively.

Results

The patients included 15 men and five women, and their ages ranged from 19 to 92 (median age of 61) years. The most common lesions were on the extremities, followed by the trunk. Histopathological examination showed atypical lymphocyte infiltrate in dermis and subcutaneous fat. The tumour tissue showed vascular proliferation, vascular occlusion, and coagulation necrosis. In situ hybridisation revealed that 20 patients were positive for Epstein–Barr virus-coding ribonucleic acid. Immunohistochemistry showed that the tumour cells were positive for CD3 (18/20 and 90%), CD56 (19/20 and 95%), T-cell intracellular antigen (TIA-1) (13/14 and 92.9%) and CD20 (5/20, 25%). About 20 patients were positive for Ki-67 with values of 30–90%. A total of 11 of the 20 patients died, and two patients were lost to follow-up. The 2-year overall survival was 24%, and the median overall survival was 17 months. Univariate analysis revealed that involvement of lymph nodes (P = 0.042) correlated with worse survival.

Limitation

This is a retrospective study design and has a limited number of patients.

Conclusion

CENKTL is rare and has a poor prognosis. Diagnosis is challenging due to non-specific clinical symptoms and histopathology results. A comprehensive judgement should be made based on related clinical manifestations and histopathological and molecular examination. Lymph node involvement is an independent prognostic factor for CENKTL.

Published: March 2023

Structural diversification of lead molecules is a key component of drug discovery to explore close-in chemical space. Late stage functionalizations (LSFs) are versatile methodologies capable of installing functional handles on richly decorated intermediates to deliver numerous diverse products in a single reaction. Predicting the regioselectivity of LSF is still an open challenge in the field. Numerous efforts from chemoinformatics and machine learning (ML) groups have made significant strides in this area. However, it is arduous to isolate and characterize the multitude of LSF products generated, limiting available data and hindering pure ML approaches. We report the development of an approach that combines message-passing neural network and an 13C NMR-based transfer learning to predict the atom-wise probabilities of functionalization. We validated our model retrospectively and with a series of prospective experiments, showing that it accurately predicts the outcomes of Minisci-type and P450 transformations, outperforming state-of-the-art Fukui-based reactivity indices.

Authors: Jiang Song , Zhang Tianjin
Published: March 2023

This article discussed a novel hydrogel, which was created through Michael addition. Two precursors dextran functionalized maleimide groups and hyaluronic acid functionalized thiol groups were designed, prepared, and characterized by NMR. The formed hydrogels were investigated by gelation time, swelling studies, viscoelastic properties, degradation rate. Based on gelation time observation, we detected that the hydrogel gelation time could be varied with diffident weight percentage of precursors. Based on previous research, we measured that 2% dextran with maleimide groups and 2% hydronic acid with thiol groups is the optimal formular for the biomedical application and this formular was also investigated by other studies. The swelling study indicated hydrogel has good flexibility and the degradation test indicated hydrogel is biodegradable. The viscoelastic test indicated hydrogel is elastic solid. From these studies, this a novel hydrogel could be potential for biomedical applications.
Computational Discovery of Stable Metal-Organic Frameworks for Methane-to-Methanol Catalysis

Published: March 2023

The challenge of direct partial oxidation of methane to methanol has motivated the targeted search of metal-organic frameworks (MOFs) as a promising class of materials for this transformation because of their site-isolated metals with tunable ligand environments. Thousands of MOFs have been synthesized, yet relatively few have been screened for their promise in methane conversion. We developed a high-throughput virtual screening (HTVS) workflow that identifies MOFs from a diverse space of experimental MOFs that have not been studied for catalysis, yet are thermally stable, synthesizable, and have promising unsaturated metal sites for C–H activation via a terminal metal-oxo species. We carried out density functional theory (DFT) calculations on the radical rebound mechanism for methane to methanol conversion on models of the secondary building units (SBUs) from 87 selected MOFs. While we showed that oxo formation favorability decreases with increasing 3d filling, consistent with prior work, previously observed scaling relations between oxo formation and hydrogen atom transfer (HAT) are disrupted by the greater diversity in our MOF set. Accordingly, we focused on Mn MOFs, which favor oxo intermediates without disfavoring HAT or leading to high methanol release energies—a key feature for methane hydroxylation activity. We identified three Mn MOFs comprising unsaturated Mn centers bound to weak-field carboxylate ligands in planar or bent geometries with promising methane to methanol kinetics and thermodynamics. The energetic spans of these MOFs are indicative of promising turnover frequencies for methane to methanol that warrant further experimental catalytic studies.

Study of the Impact of the Visual Environment on a Human Depending on the Indicator of Personality Traits
Authors: Kopylova N. Yu. ,   Irkutsk State University, Cherkasov D. V. ,   Irkutsk State University
Published: March 2023

The rapid change in the environment comes into conflict with the psychophysiological capabilities of vision and the human organism as a whole, which leads not only to myopia, but also to an increase in the number of mental illnesses. In this paper we investigated the effect of an aggressive visual environment on groups of people divided by psycho-types. To divide were used the scores of the introversion-extroversion scale as revealed by Eisenk's 57-question test. Functional indices were taken after exposure to comfortable and aggressive visual environment (CVE and AVE), specially made two video clips, using the following tests: state self-assessment questionnaire (SAQ), in, as well as “Pilots test” – a video game (when the functional capacity of the body decreased faster error was admitted). Analysis of the results of the experiment allows us to conclude: – Mann-Whitney criterion showed the existence of statistically significant differences at the significance level p < 0.05 between the samples of SAQ indicators before and after exposure to ABC, confirming its negative impact on human well-being; – reliable statistical correlation of test indicators between each other testifies to the detectable influence of the aggressive visual environment on people with different psycho-types; – absence of reliable correlation between the degree of extraversion of introversion and test scores, although observations indicate that introverts in general react more pronouncedly to the impact of aggressive visual environment due to their higher sensitivity to external stimuli and their low stress-resistance; – In order to clarify the specifics of the influence of an aggressive visual environment on people with different psychotypes, the use of multiple techniques or techniques with multiple indicators, or the study of other personality characteristics, such as neuroticism or attention deficits, seems promising.

Unpacking the Prison Food Paradox: Formerly Incarcerated Individuals’ Experience of Food within Federal Prisons in Canada
Authors: Wilson Amanda
Published: March 2023

This paper presents findings from a survey conducted with formerly incarcerated individuals on their experiences of food and food systems within federal prisons in Canada. Beyond affirming the many problems with the quality and quantity of food provided to incarcerated individuals, the findings discussed in this article highlight the multi-faceted and paradoxical role of food behind bars. Food was a tool of punishment and a site of conflict, yet it simultaneously provides an important source of community and camaraderie. While there can be no “just” carceral food system because carceral systems are inherently unjust systems, a conversation about food provisioning within prison helps bring into focus opportunities to improve the material conditions of incarcerated individuals in the short-term as well as openings to question the logic and legitimacy of carceral institutions more broadly. As we are all bound-up in carceral food systems, there is a collective responsibility to interrogate and make visible the realities of carceral food systems in order to work towards non-carceral futures.

Zero Tolerance vs Restorative Justice in the United States
Authors: Battjes Kimberly , Zane Kaplan Lilly
Published: March 2023

As schools across the United States begin to move away from the harsh Zero Tolerance policies that characterised the better part of the previous three decades, there is an opportunity to change the focus of school discipline. Frequently, school discipline policies are centred on punitive approaches that separate students from their peers. Rather than meeting the needs of these students, schools alienate them from their peers, teachers, and school communities. The goal of the education system is to provide children and adolescents with a quality education that will allow them to grow into productive and participating members of society. Zero Tolerance and school discipline policies were created to protect students, but, in practice, these policies have proven to be harmful and have unintended consequences. Too often, punitive disciplinary action in the school setting puts students on a pathway that leads into the juvenile or criminal justice system. Although the Zero Tolerance policy is a federal initiative, many states are beginning to realise the harmful impacts this policy has on students, especially marginalised students. As a result, states are beginning to pass legislation that veers away from Zero Tolerance, focusing more on alternatives like restorative practices. This article will explore these issues and share information on policies current states are using and the implications of these policies on students, as well as the school-to-prison pipeline.

Published: March 2023

India has achieved significant improvement since 2000, yet there are still areas of alarm, notably with regard to child nutrition. Adequate nutrition during infancy and early childhood is critical to each child’s development of his or her full human potential. The period from birth to two years of age is widely acknowledged as a “critical window” for promoting optimal growth, health, and behavioral development. The present study was conducted on 500 mothers of infant and young children (0-24 months) visiting OPDs of government and private hospitals of district Mohali. The respondents were interviewed using a questionnaire provided by WHO (WHO, 2021). It was found that only a few mothers (n=20) practiced hand expression of breast milk irrespective of the type of hospital visiting. A majority gave pre-lacteal food among those visiting both the private and government hospitals. 89.4 percent (n=447) had ever breastfed their infants while a majority visiting government (52.1%) as well as private (53.3%) hospitals practiced exclusive breastfeeding. Reasons for stopping breastfeeding included medical advice, family advise, perceived decreased milk production or birth of another child. IYCF practices were found to be similar amongst mothers visiting the government and private hospitals. Therefore, breastfeeding counselling at antenatal clinics and peer support for exclusive breast feeding as per WHO recommendations should be included as part of breast-feeding promotional programs both in private as well as government hospitals, dispensaries and clinics.

The impact of the cultural familiarity of literary texts on learners' attitudes towards reading: A case study on the perceptions of L2 english teachers
Authors: Yıldıray Kurnaz , Erdem Akbaş
Published: March 2023

The authenticity and familiarity of the reading materials used in English as a Foreign Language (EFL) classes have received a great deal of attention for some time. The aim of the present study is to report on the qualitative analyses of secondary school EFL teachers' perceptions about the influence of cultural familiarity on reading skills development. With the qualitative nature of the data collection and analysis, a deeper insight is sought into EFL teachers' ideas about the issue with a special focus on the factors affecting their perceptions. The participants were three EFL teachers working in different secondary schools in Turkey. For data collection, in addition to completing prior semi-structured interview forms, the teachers completed posterior semi-structured interview forms after implementing two forms of the same text in both control and experimental groups of students. This also enabled the researchers to zoom in on any possible differences in the teachers' views before and after the implementation process. The results showed that the participant teachers' general perceptions about authenticity or familiarity were neither positive nor negative. Detailed analysis showed that both sides claimed to have some advantages and disadvantages even though cultural familiarity was observed to be favoured relatively slightly against authenticity. Also, each teacher, including the one favouring authenticity, stated that their students were relatively more enthusiastic about participating in activities related to the text familiar to their culture. The lack of sample diversity could be considered a limitation of the study as the number of participants were small and they were all working in the same province.

Numerous studies have been made by the concrete researchers on replacing fine aggregate with construction and demolition waste, but possibly only few materials have been proved to be successful replacement materials for natural fine aggregate in concrete. The present paper explores the results of replacing river sand with Brick Aggregate (BA) which is available in the form of construction waste. The mechanical and microstructural properties of self-compacting concrete by partially replacing river sand with brick aggregate are examined and is compared with Self Compacting Concrete (SCC). The test results showed that the strength achievement of brick aggregate concrete is comparable to self-compacting concrete and the microstructural properties have shown that the brick aggregate has an advantage of internal curing effect.
Energy efficient quality routing protocol for WSNs
Authors: Charles A.
Published: March 2023

Timely emerging research technology increases the need for real-time applications in Wireless Sensor Networks (WSN), which has made quality-based communication protocols an interesting and hot research topic. More specifically, network protocols must cope with power constraints while providing accurate quality assurance. In many of these applications, network traffic consists of delay-sensitive traffic and delay-tolerant traffic. Therefore, Quality of Service (QoS) routing becomes an important issue. The main purpose of this idea is to develop a way to improve the quality of the network and further improve throughput while at the same time creating an energy-saving method with excellent quality of service. This paper proposes to model an Energy Efficient Qualitative Routing Protocol (EEQRP) method based on an energy-efficient protocol that can be used to develop a fast, miniaturized, more energetic, and efficient way than existing routing protocols. It evaluates and compares the performance of the routing protocol (EEQRP). The Network Simulator-2 (NS2) is used to run and test the proposed system, which provides lower average latency, greater power savings, and a higher packet delivery rate than the current protocol.

Abed Al-Jabiri's Epistemology of Intelligence: A Case Study of Interfaith Marriage in Indonesia
Authors: Sutono Agus , Noorzeha Fuad
Published: March 2023

Interfaith marriage/mixed marriage is currently an unresolved social polemic. It means that the marital status of different religions is still a hot topic of discussion because seeing the impact caused by interfaith marriages is very large. These impacts are child care, inheritance rights, child morals, and up to divorce. Often, interfaith marriages occur based on freedom of reasoning in religion. Thus, for people in an interfaith marriage, the perception of reason provides legal justification to strengthen the legality of interfaith marriages. Therefore, various efforts in interfaith marriages continue to be carried out in Indonesia. This research used the epistemology of Abed al-Jabiri, namely: Bayani, Burhani, and Irfani to emphasize reason as Idraku al-Sabab Wa al-Musabbab and reason as Bila Wasitah. This method is different from the epistemological methods of other figures such as Ibn Rushd and Ibn Khaldun. Thus, the researcher used al-Jabiri's epistemological trilogy as a method of thinking to see the freedom of reasoning in interfaith marriages. This research was qualitative research with heuristic methodical elements and used an epistemological approach. The heuristic method provides criticism of a certain paradigm so that the consequences of criticism become an alternative to a new paradigm. The results of this research were Abed al-Jabiri's criticism through an epistemological trilogy to provide limits on freedom of reasoning in interfaith marriages.

Voleybolla məşğul olmağa başlayan yeniyetmələrlə aparılan işlər məqsədyönlü və prespektiv xarakter daşımalıdır. Yüksək idman ustalığına nail olmaq məsələləri aşağı yaşlı uşaqlardan ibarət bədən tərbiyəsi kollektivlərində həll olunması daha məqsədəuyğundur.

Voleybol məşğələlərinin il boyu sistematik və müntəzəm qaydada keçirilməsi son dərəcə vacibdir. Əks halda yüksək idman nəticələrinə nail olmaq mümkün ola bilməz. Bir qayda olaraq idman məşğələlərində müntəzəm qaydada iştirak etməyən uşaqlar texniki və taktiki cəhətdən yaxşı formalaşa bilmirlər. Belə olan halda onların texniki və taktiki hazırlığı natamam, texnikası isə qeyri-dəqiq olur.

As time goes by, the number of documents or files or archives in a company continues to increase. These files are in the form of data collection, activity reports, accountability reports, work proposals, letters, decrees, regulations, and so on. At first, the company tried to convert paper-based files into digital files, then took advantage of several free platforms to store them. Furthermore, companies find it difficult to control digital files because of the non-centralized storage. Finally, companies are trying to create various information systems that allow them to centrally manage digital files. A large number of digital files in it makes the search process even longer, so it is necessary to optimize the search features. The purpose of this study is to review several algorithms that have been implemented to optimize file searches in previous studies. This research takes Indonesian scientific articles from Google Scholar from 2015 to 2022. The result of this research is the explanation of the use of algorithms in previous studies so that this research can become a reference and suggestion for further research. This study found the fact that every information system or application that functions to manage company files or archives requires a search algorithm to improve system performance

Rapid softening is one of the main problems of soursop (Annona muricata L.) fruits. The physicochemical parameters and gene expression response of cell-wall-related genes in soursop fruits were evaluated. The temperature of 15 ± 2 °C delayed the physicochemical composition of soursop fruits by three days and significant down-regulated the expression of cell-wall related genes. Pectin methylesterase (PME1), pectate lyase (PL22), polygalacturonase (PG), Endoglucanase (EG), and expansins (EXP13 and EXP7) genes showed a down-regulation of their expression during ripening at 28 ± 2 °C and 15 ± 2 °C. The bioinformatic analysis demonstrated two conserved domains associated with degradation of cell wall. Higher gene level of the EXP7 gene was detected on Day 6 of storage at 28 ± 2 °C, showing a 3.5-fold increase in the gene expression compared to Day 0. Furthermore, PME1, PL22, PG, EG, and EXP13 expression was down-regulated by the temperature of 15 ± 2 °C (p < 0.05). Gene expression was highly correlated in the fruits stored at 28 ± 2 °C. On the other hand, a high correlation between the EXP7, PME1, and PL22 genes was recorded on the fruits stored at 15 ± 2 °C. The multivariate analysis demonstrated that acidity is an important variable during ripening and the two EXP genes, and EG are highly correlated with acidity and negatively correlated with firmness. In conclusion, the findings of this research suggest that these genes are down-regulated by the combination of days of storage and temperature.
Development of a test instrument using multiple representations to assess students understanding: A Rasch Model Analysis

Today's test instruments used in schools are still ineffective in assessing students' multi-representational understanding of the "rate of reaction" topic. Hence, teachers need to accurately and comprehensively know the depth of students' understanding. In this study, a test instrument was produced to assess the level of macroscopic, submicroscopic, and symbolic understanding of high school students in the rates of reaction topic. The method used is Research and Development (R&D) based on the Rasch modeling approach, which is modified in ten stages, i.e., (1) defining construct, (2) identifying question indicators, (3) compiling items, scoring rubrics, scoring guidelines, and the guidelines to analyze student's level of understanding, (4) conducting the pilot test, (5) analyzing data with the Rasch model, (6) reviewing the suitability of items, (7) reviewing the Wright map, (8) repeating steps 4-7 until all items fit, (9) claiming the instrument's quality, and (10) documenting the instrument. All items proved valid because they met the fit criteria of MNSQ, ZSTD, and PT Measure scores. Instrument reliability reaches the score of 0.89 (good). The instrument has a four-difficulty index, dominated by moderate difficulty (70.6%). This instrument is relatively easy. The instrument also has four discrimination indexes: very difficult, difficult, medium, and easy. It proves that this assessment instrument is of good quality and suitable for school use.

School exam is one of the benchmarks of student learning outcomes as a test that is expected to provide information on the ability of students that can be used to consider and describe the achievement of students, especially in physics subjects. This study aims to describe the suitability of fixed vs. emergent design, formative vs. summative design, experimental design, and quasi-experimental vs. natural inquiry evaluation of the implementation of school exams in physics subjects in high school. This research uses the Brinkerhoff evaluation model proposed by Robert O. Brinkerhoff. The method used in this research is quantitative, and this type of research is evaluative. The data collection technique used a questionnaire, supported by observation and documentation, and a literature study to give meaning to the research results. The results showed that overall the organization of school exams in physics subjects in high school was very good. In the fixed vs. emergent design component, a total average of 95% is obtained from the teacher's perspective and 87% from the student's perspective, which is very good. Furthermore, for the formative vs. summative design component, a total average of 94% was obtained from the teacher's perspective and 88% from the student's perspective, which was in the excellent category. Then the experimental design and quasi-experimental vs. natural inquiry obtained a total average of 96% in the teacher's perspective and 88% in the student's perspective, which is in the excellent category. Thus, the implementation of school exams in physics subjects in high school is very good, but further research needs to be carried out to analyze, maintain, and at the same time improve what is lacking in terms of organizing school exams, starting from the preparation, implementation, and closing stages.
