Generalized metric for broadband flat lens performance comparison
Authors: Engelberg Jacob , Levy Uriel
Published: July 2022

A plethora of metalenses and diffractive lenses (“flat lenses”) have been demonstrated over the years. Recently, attempts have been made to stretch their performance envelope, particularly in the direction of wide-band achromatic performance. While achromatic behavior has been demonstrated, showing an actual improvement in imaging performance relative to conventional (non-chromatically corrected) flat lenses has remained a major challenge. The reasons for this are use of inappropriate performance metrics, lack of comparison to a baseline conventional design, and lack of a performance metric that combines signal-to-noise ratio and resolution. An additional problem is that different published flat lens designs use different first order parameters, so they cannot be compared. In this work we present an overall performance metric that will allow comparison of different types of flat lenses, even if their first order optical parameters are not the same. We apply this metric to several published achromatic flat lens designs and compare them to the equivalent conventional flat lens, which we consider as the lower bound for achromatic flat lens performance. We found that the performance of the achromatic flat lenses studied does not surpass that of a conventional diffractive lens. Use of this metric paves the way for future developments in the field of achromatic flat lenses, which will display proven progress.
Profitability and financial performance of European Union farms: An analysis at both regional and national levels
Authors: Martinho Vítor João Pereira Domingues
Published: July 2022

Agriculture has always been a sector with several specificities that call for adjusted interventions from public institutions through agricultural policies. This is not an exception for the context in the European Union where the Common Agricultural Policy has had more impact in some contexts than the national agricultural policies of the member-states. In turn, the profit margins are, in general, narrow and this needs specific financial and economic management. However, the financial, economic instruments, and indicators for farming are, often, ignored, or at least, not sufficiently analysed. From this perspective, the main objective of this study is to assess the net working capital framework across European Union countries and regions, including assessments through types of farming and economic size. Another objective is to analyse the impacts from financial indicators (current ratio, current assets-to-total assets ratio, current liabilities-to-total assets ratio, and debt-to-total assets ratio) on profitability (return on assets) and financial performance (return on equity). For this purpose, data from the Farm Accountancy Data Network were considered, for the period 2004–2018. These data were worked through descriptive analysis, spatial autocorrelation approaches, and panel data regressions. As main conclusions, it is worth noting the diversity of financial realities across the European farming sector and the null impacts from the liquidity ratio on the farms’ performance.
Bi2O3–PbO–CdO–B2O3 glasses: competent candidates for radiation shielding
Authors: Aloraini Dalal Abdullah , Sayyed Mohammad.I. , Almuqrin Aljawhara H. , Kumar Ashok , Mahmoud Karem. A.
Published: July 2022

The Bi2O3–PbO–CdO–B2O3 glasses were shaped via the melt-quenching process. The XRD spectra reveal that the glasses are composed of amorphous material. Four distinct bands may be seen in the FTIR spectra at wavelengths between 400 and 600, 600–800, 800–1200, and 1200–1500 cm−1 range. This is due to a variety of bond stretching and vibration modes present in the system. A Monte Carlo simulation was used to verify the radiation shielding capabilities. The µ values grow as the amount of Bi2O3 in the manufactured glasses increases. The rise in µ values was coupled with a drop in the Δ0.5 values when the Bi2O3 concentration was increased. Additionally, the TF and RPE values were influenced by the enhancement in the µ values, with the RPE increasing from 34.61 to 44.42 percent and the TF values decreasing from 65.39 to 55.58 percent at 0.662 MeV when the Bi2O3 concentration was increased. The study showed that raising the Bi2O3 content improves the shielding capabilities. Thus, the produced glass samples, particularly BPCB25, exhibit excellent shielding capabilities, making them suitable for use in radiation shielding fields.
Phase behavior of the sodium lauryl glutamate: effects of the temperature and concentration
Authors: Zhang Qianjie , He Chenghao , Zhang Dongmei , Jiang Wen , Zhang Huiwen , Zhang Wanping
Published: July 2022

The physical and chemical properties of sodium lauryl glutamate were systematically investigated in this work. To determine the critical micelle concentration (CMC) of sodium lauryl glutamate, the surface tension was measured using the Wilhelmy plate method. The Krafft point was determined using the ultraviolet/visible spectrophotometer. The effect of pH on the solute in the solution was studied using potentiometric titration. The critical packing parameter (CPP) and Gibbs free energy (ΔG) of micelle formation were calculated using the corresponding parameters. The temperature-concentration phase diagram of sodium lauryl glutamate was constructed using the dynamic light scattering system (DLS) and polarised optical microscopy (POM). The calculated theoretical data were combined with the actual observed data from the phase diagram. Finally, the phase behaviour of sodium lauryl glutamate was determined.
Covid-19, Ungleichheit und (Erwerbs-)Arbeit – zur Relevanz sozialer Klasse in der Pandemie
Authors: Holst Hajo , Fessler Agnes , Niehoff Steffen
Published: July 2022

Der Beitrag verbindet die Forschung zu den Auswirkungen der Corona-Pandemie mit der Debatte über die Relevanz sozialer Klasse. Mit einem klassenanalytischen Zugang (Oesch-16) und auf der Basis eines Mixed-Methods-Designs mit Erwerbstätigensurvey und qualitativen Interviews aus der Frühphase der Pandemie werden die Auswirkungen von Covid-19 auf die Arbeitswelt in fünf Themenfeldern untersucht: Infektionsrisiken am Arbeitsplatz, wirtschaftliche Lasten, mobiles Arbeiten, Arbeitsbedingungen sowie Vereinbarkeit von Erwerbsarbeit und Kinderbetreuung. Dabei zeigen sich im Bereich der Erwerbsarbeit ausgeprägte vertikale und horizontale Klassenungleichheiten, die punktuell auch auf die Schnittstelle zur unbezahlten Sorgearbeit ausstrahlen und die zudem in den Alltagserfahrungen vieler Erwerbstätiger präsent sind. Die Ergebnisse verdeutlichen die Bedeutung der Klassenlage für das Arbeitserleben in der Pandemie, verweisen jedoch auch auf Grenzen der Erklärungskraft klassenanalytischer Perspektiven.
Private Voting, Public Opinion and Political Uncertainty in the Age of Social Media
Authors: Kusche Isabel
Published: July 2022

Before the advent of social media and big data analytics, the right to vote under conditions of ballot secrecy ensured a complementary relationship between the privacy of the voting act and political self-observation as a second-order observation in democratic political systems. Key to this relationship is the notion of public opinion. This notion and its relevance for professional political actors in dealing with political uncertainty are at stake in the age of social media. The privacy of the voting act becomes a problem once it is believed to be subject to the overriding influence of algorithmic recommendation and targeted advertising.
Coronary Angiography Within 48 Hours Before Cardiac Surgery Increases the Risk of Postoperative Acute Kidney Injury
Authors: Zhou Heping , Xiong Hongyan , Zheng Xinglong , Yang Huan , Xu Suochun
Published: July 2022

Background: Cardiac surgery and coronary examination, such as invasive coronary angiography (CAG), are both possibly associated with acute kidney injury (AKI). Preoperative CAG examination and cardiac surgery within a short interval may increase the incidence of AKI.
Methods: We retrospectively reviewed 1112 patients who underwent CAG examination within 30 days prior to the cardiac operation in this study. Postoperative AKI was defined, according to Kidney Disease Improving Global Outcomes Definition and Staging (KDIGO) criteria.
Results: The total incidence of AKI was 40.8% and cystatin C level was 1.260 (1.028, 1.672) mg/L. For patients who received CAG, age, body mass index, cardiopulmonary time, and the time interval between preoperative CAG examination and cardiac operation within 48h was shown to be independent predictors of postoperative AKI. The incidence of AKI in patients undergoing preoperative CAG within 48h was 11.2% higher than in those more than 48h (P < 0.001). Patients undergoing valve surgery with or without coronary artery bypass grafting (CABG) exhibited a higher AKI risk than those only accepting CABG. The in-hospital stay of patients who developed AKI was 2 days longer than those without AKI. However, undergoing CAG within 48h prior to cardiac operation did not prolong ICU length of stay or hospital length of stay, nor did it increase the risk of death or renal failure after an operation.
Conclusion: Undergoing CAG within 48 hours before cardiac surgery increases the risk of postoperative AKI.
Endoscopic Versus Conventional Vein Harvest Technique: Histological and Immunohistochemical Evaluation of Venous Wall Integrity
Authors: Aboollo Moustafa F , Awadallah Khaled M , Elsharkawy Tarek , Abd Elaziz Montaser Elsawy , Hafez Bassem A
Published: July 2022

Background: The introduction of endoscopic saphenous vein graft harvesting has been known for two decades. It offers benefits related to decreased rate of donner site complications. Debates related to its safety in terms of trauma to the wall of the venous graft and long-term graft patency have been raised, but few studies had investigated this point. Our aim is to compare the endoscopic saphenous vein harvest and conventional harvest techniques, in terms of the integrity of the wall of the vein graft.
Methods: A prospective study in which we examined 80 samples of saphenous vein from 80 patients to whom coronary artery bypass grafting was done. Patients randomly were assigned to either technique. Vein samples were taken from patients having the conventional technique (group 1, 40 patients) and from patients having endoscopic vein harvest (group 2, 40 patients). Vein samples were stained with Hematoxylin & Eosin, Masson’s trichrome, and immunohistochemical stain for CD 31 and then examined by light microscopy. The degree of intimal staining was graded from 0% to 100%, which is directly related to the degree of intimal preservation (the least injury, the more the staining score) and vein media changes were reported.
Results: Patient characteristics were comparable in the groups. Group 1 (conventional group) was better than group 2 (endoscopic group), regarding endothelial integrity and medial changes although it was statistically not significant.
Conclusion: Both the conventional and endoscopic techniques are comparable, regarding the intimal preservation of the venous graft.
A Complex Case of Pregnancy-related Left Main Stem Spontaneous Coronary Artery Dissection
Authors: Mailey Jonathan A , Thompson Patrick , Johnston Paul W , Owens Colum G
Published: July 2022

Spontaneous coronary artery dissection (SCAD) is a less common cause of acute coronary syndrome. Pregnancy-related SCAD is uncommon, but often presents with a more severe phenotype. This report describes a 30-year-old woman with an anterior ST elevation MI, presenting 1 day postpartum. Left main stem (LMS) SCAD with extensive intramural haematoma (IMH) and resultant LMS occlusion was confirmed by angiography and intravascular imaging. Given the extent of disease, the patient underwent emergency cardiac surgery. Coronary flow was initially improved by decompressing the IMH using cutting balloons. The coronary wires were successfully left in situ during transfer in an effort to both maintain flow and allow the surgeon to identify true LMS. Ideally, SCAD can be managed conservatively given the risk of intervention worsening IMH, and hence myocardial ischaemia/MI. However, emergency revascularisation is indicated in cases of persistent ischaemia. This case demonstrates percutaneous therapies to bridge towards and help with subsequent surgical revascularisation.
Entre Romanticismo y Modernismo, entre poesía y prosa: el doble eclecticismo en tres poemas en prosa de Carmen Lyra
Authors: Campos López Ronald
Published: July 2022

En este artículo se estudian tres poemas en prosa de Carmen Lyra: “Balada de noviembre” (1911), “La leyenda de las rosas blancas” (1913) y “Del diario de Juan Silvestre” (1917). En ellos se analiza un doble eclecticismo que (con)funde, por un lado, cualidades genéricas de la poesía y la prosa, y, por otro, cualidades estéticas, temáticas e ideológicas del Romanticismo y el Modernismo. Este doble eclecticismo tiene como objetivo promover la transgresión estética y formal que difumina los límites, de manera productiva, con miras a la originalidad y la belleza artística. Se parte de la hipótesis de que la (con)fusión del Romanticismo y el Modernismo proviene de la Lira costarricense (1890) y que, la de poesía y prosa, de tres fuentes: 1) “La noche oscura” (1893), de Aquileo Echeverría; 2) la misma libertad formal que dichos movimientos literarios y culturales promueven; y 3) el eclecticismo practicado por Lyra en su pedagogía. La tesis se comprueba con base en el análisis del paisajismo, la sensualidad y sensorialidad, la densidad adjetival, la prosopopeya, la proyección subjetiva en la naturaleza, la nostalgia, la contemplación metafísica, la trascendencia, el neoespiritualismo, la duda, el desencanto, el pesimismo, la decadencia, la actitud cívica, el tiempo, el exotismo, la vaguedad, la melancolía, la libertad formal y el aristocratismo. Finalmente, se invita a revisar los modos de leer, analizar y catalogar los textos de Lyra, para recuperar textos suyos, proponer nuevas lecturas y ampliar el canon oficial. Además, se recomienda profundizar en otros poemas en prosa que igualmente manifiestan este doble eclecticismo, a fin de trazar su historia.
El liderazgo pedagógico del docente de Español ante los nuevos programas de Lengua y Literatura: una oportunidad de transformar realidades
Authors: Chinchilla Araya Tatiana
Published: July 2022

Se propone en este documento un perfil ideal del docente de Español, al trasladar, de forma contextualizada, las habilidades de liderazgo pedagógico que todo docente debería desarrollar para su trabajo con la comunidad educativa, en relación específica con esta asignatura y los objetivos de formación perseguidos. Lo anterior, como una manera de revisar las competencias y destrezas necesarias para que estos profesionales sean capaces de llevar a la práctica, de maneras efectivas, los objetivos y contenidos propuestos en un nuevo programa que vino a romper los esquemas tradicionales de la DLL en las instituciones costarricenses. El docente debe estar convencido del papel que tiene como transformador de la realidad de aula, como líder potencial y real de esos cambios en el aprendizaje de la Lengua y la Literatura, para bien de la sociedad. Lo anterior desde las herramientas que el programa de estudios actual le permite, para que sea posible vislumbrar cambios en las habilidades comunicativas de las personas, a corto plazo, las cuales trasciendan la memorización de reglas gramaticales y lecturas acríticas. De esa manera, se establecen algunas visiones críticas sobre la forma en que los educadores han percibido y aplicado los nuevos parámetros expuestos en el programa de Español actual, así como una propuesta reflexiva sobre el perfil del profesor de Español como líder pedagógico, quien tiene en sus manos la posibilidad de que la propuesta ministerial trascienda los documentos, de forma tal que se produzcan cambios concretos en la forma de percibir la materia de Español, por parte de la comunidad educativa.

Transitar la frontera: Fricciones, desencadenantes y oportunidades para la integración de conocimientos en proyectos de Acción Social
Authors: Villalobos Ramírez Susana María
Published: July 2022

La integración de conocimientos se plantea como la capacidad de agrupar diversos cuerpos de saberes para resolver problemas complejos y facilitar la innovación. El objetivo del texto es dilucidar posibles fricciones, desencadenantes y oportunidades para fomentar procesos de integración entre los responsables de los diversos proyectos de Acción Social como una estrategia de innovación social en el contexto académico. La metodología implicó la recolección de información mediante dos fuentes primarias: primeramente, se aplicaron entrevistas a una muestra de dieciséis informantes calificados, a partir del análisis de los datos recolectados se realizó una categorización y se detectaron necesidades que permiten identificar doce oportunidades de “Innovación guiada por resultados” (Ulwick, 2014). En una segunda etapa de investigación, esas doce oportunidades se incorporaron en un cuestionario en el que se solicitó a una muestra de veinticinco informantes la calificación del grado de satisfacción y del grado de importancia mediante una escala de Likert de cinco puntos sobre cada oportunidad. Conjuntamente se revisaron publicaciones relacionadas con la gestión y transferencia de conocimientos. Los resultados de esta identificación exploratoria muestran que algunos desencadenantes para la integración se dan bajo condiciones emergentes, el sentido del deber y el propósito. La colaboración entre pares se da en la medida en que las necesidades básicas de seguridad, beneficio percibido y reciprocidad son satisfechas. La cuantificación de resultados demuestra la necesidad de brindar formación y motivación para implicarse en procesos integradores que resulten en mayor innovación. Por último, se plantean consideraciones para el análisis prospectivo del caso.
Where to put Compulsive Sexual Behavior Disorder (CSBD)? Phenomenology matters •
Authors: Rumpf Hans-Jürgen , Montag Christian
Published: July 2022

In this commentary paper, it is discussed if Compulsive Sexual Behavior Disorder (CSBD) is best categorized as an Impulse Control Disorder, an Obsessive-Compulsive Disorder or in light of the overlap of characteristics with both Gaming and Gambling Disorder as an addictive behavior. The overlapping features are: loss of control over the respective excessive behavior, giving increasing priority to the excessive behavior under investigation and upholding such a behavior despite negative consequences. Besides empirical evidence regarding underlying mechanisms, phenomenology also plays an important role to correctly classify CSBD. The phenomenological aspects of CSBD clearly speak in favor of classifying CSBD under the umbrella of addictive behaviors.
Deconstructing the Dichotomy of Agama and Kepercayaan: A Transformative Strategy in the Politic of Recognition towards Marapu Indigenous Religion
Authors: Deta Krisharyanto Umbu
Published: July 2022

The category of agama is mainly referred to the six recognized world religions in Indonesia while kepercayaan is a general terminology that is used to accommodate the Indonesian indigenous religions. The indigenous religions are excluded from the category because agama has been perceived in a very essentialist way making it being differentiated. Recently, the Constitutional Court Decision in 2017 allowing indigenous religions to put their religious identity in their ID Card has been considered as the most progressive changes in the politics of religion in Indonesia. In that regard, this work will deconstruct the problematic dichotomy as a form of transformative strategy for gaining recognition. This research uses Nancy Fraser and Kristian Stokke’s frameworks of the problem of misrecognition and its affirmative and transformative remedies as the main theoretical frameworks. This research found that what has been done mostly so far in the effort of gaining recognition is arguably a part of affirmative strategy. By examining the specific case of the Marapu community, this work would also have significance to the Indonesian indigenous religions in general whose problem of recognition is also rooted in the dichotomy.
The Contribution of Ibn Qayyim al-Jawziyya to Salafi Sufism
Authors: Satriawan Lalu Agus
Published: July 2022

This article aims to explore the Ibn Qayyim al-Jawziyya’s original views on Sufism. Ibn Qayyim is regarded as an authority in Salafi circles who reject Sufism as a legitimate representation of Islam, especially its philosophical orientation. This article uses a literature research model to reach the finding that Ibn Qayyim understood Sufism as a moral system and part of the science of Islamic morality. Sufism aims to purify the soul to prepare it for its return to God along the path of love. The basis of Sufism as revised by Ibn Qayyim was the Qur’ān, the Sunnah, the traditions of the companions, the ideas of Ibn Taymiyya, and the teachings words of the early Sufi masters. Ibn Qayyim strongly adhered to the orthodox principles of Islamic scholarship later dubbed as Salafism, especially in terms of prioritizing the shari‘a over reason and rejecting esoteric interpretation (ta’wīl). For Ibn Qayyim, the Sufi philosophers were misled in overly relying on ta’wīl and disregarding the role of reason. His approach to Sufism was to perform an objective evaluation of the Sufi teachings circulating at his time. Instead of joining either side, the side of those who condemned it as unlawful innovation (bid‘a) or the side of those who accepted it uncritically, Ibn Qayyim chose to conduct an extensive review of its ideas and practices, rejecting those elements that he found objectionable and accepting others that he found commendable.

High-throughput growth rate measurements on solid media using surface density v1
Authors: DeAngelis Kristen
Published: July 2022

Growth curves are an essential tool in the measurement of microbial traits, but many microbes are unable to grow homogeneously in liquid culture. In some ecosystems, like foods and soils, surface-associated growth is the dominant mode of growth among the diversity of microbes. In order to understand microbial growth rates and to estimate how growth rate changes with biotic and abiotic factors like temperature, substrate quality, or in the presence of biological agents, we developed a high-throughput solid state growth protocol that uses surface density. Bacterial isolates were inoculated onto solid media cast in 6-well plates, and measures of surface density were collected as well scans of optical density at 600 nm in 177 pixels across a single well. Surface density is calculated as the sum of optical densities across the well after subtraction of media blank negative control OD600nm values. We observed substantial improvement in growth curve fits after removal of edge pixels, which contributed to noise in the model fits. Surface density allows for microbial growth to be estimated as a Gompertz model fit because of the third dimension of data collected as cell density, whereas traditional methods of colony area appear to be best fit using a linear function. We present this method along with custom scripts to collect and analyze this data as a way of improving the measurement of solid phase growth among microbes.

Increasing insulin measurement throughput by fluorescence anisotropy imaging immunoassays v1
Authors: Wang Yao
Published: July 2022

Insulin secreted from islets of Langerhans is the main hormone to reduce blood glucose. Examination of insulin secretion patterns at the single islet level reveals functional differences in the timings and patterns of release. This heterogeneous response highlights the importance of developing systems to measure dynamic release from small numbers of islets in parallel. Toward this, we describe fluorescence anisotropy imaging immunoassays as a relatively simple method for increased throughput of islet secretion measurements. In this system, vacuum pressure from a syringe pump pulled perfusate from 12 islet chambers and reagents into 12 parallel mixing channels for a competitive immunoassay. Light from a Xe arc lamp was filtered and polarized prior to focusing on the microfluidic device at the region where the 12 mixing channels converged. Emission was collected and passed through vertical and horizontal emission polarizers housed in an automated filter wheel before being imaged with a sCMOS camera for the determination of anisotropy. This microfluidic system was tested by monitoring insulin release from groups of murine and human islets. Heterogeneity was observed in the islet traces; however, the presence of islets affected the resistance of the islet chambers, hampering insulin quantification. Nonetheless, this microfluidic system is a step towards increasing the throughput of hormone release measurements from islets of Langerhan. Graphical abstract

Reuse of wastewater, treated by phytoremediation, for the irrigation of the Botanical Garden ‘‘le jardin Landon’’ (Biskra, Algeria). Sustainable solution for the preservation of a material heritage site
Authors: Debabèche Mahmoud , Barkat Ayoub , Boukebous Mohamed Ali
Published: July 2022

The green spaces of the city of Biskra (Algeria) resist the arid climate of the summer season and therefore suffer from water scarcity caused mainly by evaporation and transpiration of the plants. To remedy this problem, the study suggests to reuse the sewage for irrigation after being purified, using constructed wetlands with improved capacity by phytoremediation. As an example of a sustainable solution, it is proposed to apply this technique to the botanical garden of the city of Biskra (Algeria), «le jardin Landon». The design of a Constructed Wetland system is proposed. The Landon Garden was created in 1870 by Count Landon of Longueville, decorated with a variety of flora from the tropics and the Equatorial countries. It is currently considered as national material heritage.
Mobilisation des eaux de surface: Commentaires généraux sur les barrages en Algérie dans le passé, le présent et le futur
Authors: Ouamane Ahmed , Sekkour Ilyese , Athmani Bassem
Published: July 2022

L’Algérie est dans une région à climat aride, ceci nécessite une gestion rationnelle de la ressource en eau. Selon l’état des connaissances actuelles, la mobilisation des eaux par le biais des barrages a commencé par des ouvrages de dérivation avant l’époque coloniale. Pendant cette période (1830–1962), on compte l’édification de seize barrages d’une capacité totale d’un milliard de m3. Après l’indépendance, des grands barrages ont été érigés pour atteindre une capacité d’environ neuf milliards de m3 en 2020. La préservation de ces ouvrages est l’une des priorités actuelles et futur. Le phénomène d’envasement risque de compromettre le développement en matière de mobilisation des eaux. Actuellement, la capacité de stockage perdue par envasement est de 11 %. Pour y remédier, des études ont été réalisées à l’université de Biskra (Algérie) avec Hydrocoop-France, qui ont permis de définir de nouvelles techniques d’accroissement de la capacité de stockage.

Government responses, democracy, and COVID-19 containment: a cross-country study
Authors: Huynh Toan Luu Duc , Duong Duy
Published: July 2022

By drawing the monthly data of 33 advanced economies in 2020, this paper explores the effectiveness of government responses and the level of democracy in containing the COVID-19 spread. Our results show that the government responses effectively ‘flatten the curve’ of infected cases and death cases. Concomitantly, the higher level of democracy simultaneously contributes the joint effect with government responses to the lower association with the number of infected cases in these countries. However, it is more noticeable that this effect does not persist or significantly exhibit heterogeneous effects. These two aforementioned points contribute a shred of empirical evidence to the existing literature about the COVID-19 studies. Therefore, our study has some relevant policy implications.

The purpose of this research is to analyze the need for developing HOTS-based mathematics teaching materials that are integrated with religion in MTs. The results of this research will later become the basis for developing religious-integrated HOTS teaching materials. The analysis stage refers to the Analyze stage in the ADDIE development model. The data collection technique was carried out by distributing questionnaires to 16 MTs mathematics teachers. This research shows that the majority of MTs mathematics teachers complain that the teaching materials are monotonous, less varied and not HOTS-based. The majority of mathematics learning that has been applied is with a scientific approach and applies 21st century learning. So far, when teaching mathematics, teachers use books, worksheets, modules, props and learning videos. Not all learning resources have been used by HOTS-based teachers. The majority of learning resources used by teachers have not been integrated with religion. The advantages of existing learning resources are that the material is complete, contextual, structured and uses a scientific approach. However, there are still shortcomings, including not being integrated with religious subjects due to the limitations of teachers regarding the knowledge of integrating mathematics subjects with material on religion, not implementing HOTS much and not being able to make students learn independently actively. From these results, it can be concluded that it is necessary to develop religious integrated HOTS- based mathematics teaching materials for MTs students.

This study examines the socioeconomic and risk behaviour of small–scale oil palm processors in Akwa Ibom State, the southern region of Nigeria. The multi-stage sampling technique was used to collect cross-sectional data from one hundred and twenty-five (125) micro-oil palm processors. The results revealed that the majority of the processors were married and males were the dominant sex. The average years of processing experience, age, membership in social organization and educational attainment stood at 11.43 years, 48.23 years, 2.78 years and 12.15 years respectively. The processors' average household size and annual income were 5 members and N319, 658.33 (at 1$ = N380.26 in 2020) respectively. The risk factors identified among the micro-oil palm processors include insufficient raw materials, poor public electricity, high cost of tools and machines and increased operation hazards. The result showed that oil palm processors in the region are risk-takers. The empirical results revealed that processors’ age, educational attainment, membership in social organization, household size, processing experience and processors’ income were significant factors influencing the risk behaviour of oil palm processors. To enhance the well-being of micro-oil palm processors in the region, emphasis should be devoted to the development of education attainment and social capital formation among others.

Background: The coronavirus disease 2019 (COVID-19) pandemic adversely disrupted university student educational experiences worldwide, with consequences that included increased stress levels and unhealthy sedentary behavior.
Aim: This study aimed to quantify the degree of impact that COVID-19 had on the levels of physical activity and stress of university students by utilizing wearable fitness tracker data and standard stress survey instrument scores before and during the pandemic.
Methods: We collected Fitbit heart rate and physical activity data, and the results of a modified Social Readjustment Rating Scale (SRRS) stress survey from 2,987 university students during the Fall 2019 (residential instruction; before COVID-19) and Fall 2020 (hybrid instruction; during COVID-19) semesters.
Results: We found indicators of increased sedentary behavior during the pandemic. There was a significant decrease in both the levels of physical activity as measured by mean daily step count (↓636 steps/day; p = 1.04 · 10-9) and minutes spent in various heart rate zones (↓58 minutes/week; p = 2.20 · 10-16). We also found an increase in stressors during the pandemic, primarily from an increase in the number of students who experienced the “death of a close family member” (38.8%), with the number even higher for the population of students who opted to stay home and attend classes virtually (41.4%).
Conclusions: This study quantifies the decrease in levels of physical activity and notes an increase in the number of students who experienced the death of a close family member, a known stressor, during the first year of the COVID-19 pandemic. These findings allow for more informed student-health-focused interventions related to the COVID-19 pandemic disruptions experienced by academic communities worldwide.

Published: July 2022

This study aimed to experimentally investigate the effects of dry flue gas on biomass torrefaction. In this work, an oil palm frond (OPF) was torrefied in a laboratory-scale horizontal torrefaction reactor at temperatures of 240, 260, and 280 °C, with a residence time of 20 and 40 min, using dry flue gas with variable compositions (N2/CO2/O2: 76/16/8, 80/14/6, and 74/12/4). In addition, the experiments of conventional torrefaction were conducted for comparison. The effects of operating parameters on mass yield, the proximate and ultimate analysis, and the heating value of the fuel were investigated. The proposed method improved the fuel property of OPF substantially. With dry flue gas, OPF had lower moisture and volatile, and higher fixed carbon. The heating value of the selected biomass increased from 14.6 MJ/kg to 25.8 MJ/kg. Therefore, torrefaction using dry flue gas exhibited a potential for practical use for the biomass fuel pre-treatment method. However, this method resulted in a decreased mass yield and, consequently, the energy yield of the sample compared to conventional torrefaction.
