Published: May 2022

High-capacity Ni-rich layered metal oxide cathodes are highly desirable to increase the energy density of lithium-ion batteries. However, these materials suffer from poor cycling performance, which is exacerbated by increased cell voltage. We demonstrate here the detrimental effect of ethylene carbonate (EC), a core component in conventional electrolytes, when NMC811 (LiNi0.8Mn0.1Co0.1O2) is charged above 4.4 V vs. Li/Li+ – the onset potential for lattice oxygen release. Oxygen loss is enhanced by EC-containing electrolytes – compared to EC-free – and correlates with more electrolyte oxidation/breakdown and cathode surface degradation, which increase concurrently above 4.4 V. In contrast, NMC111 (LiNi0.33Mn0.33Co0.33O2), which does not release oxygen up to 4.6 V, shows similar extents of degradation irrespective of the electrolyte. This work highlights the incompatibility between conventional EC-based electrolytes and Ni-rich cathodes (more generally, cathodes that release lattice oxygen such as Li-/Mn-rich and disordered rocksalt cathodes), and motivates further work on wider classes of electrolytes and additives.
Infant Simulators in the Undergraduate Curriculum: A Technological Tool for Teaching about Parenthood
Authors: Harpel Tammy S. , Egan Erin
Published: May 2022

The purpose of this paper is twofold. It describes the use of infant simulators to teach undergraduates about the experience of parenting. It also examines empirical evidence of the use of the infant simulator among undergraduates enrolled in parenting courses at two universities. In particular, the evaluative evidence explores lessons learned about parenting from the caregiving experience, along with the role of duration of the simulation on caregiving performance, reported caregiving difficulty, and lessons learned about parenting. Data from 261 students enrolled in undergraduate parenting classes at two universities were used for the evaluation. Qualitative findings indicated that students learned these lessons about parenthood: (1) It is demanding, (2) It requires patience, (3) A parent must be selfless, (4) Parents lose sleep, and (5) Single parenthood is difficult. Duration of the simulation was significantly associated with specific lessons. The evaluation data indicate that the simulator experience is a valuable learning tool for undergraduate students.
College Students Educating Children and Families on Healthy Eating and Physical Activity Using an Edible Garden
Authors: Williams-Wheeler Meeshay , Faulkner Paula E. , Huchette Odile
Published: May 2022

Although there are institutional barriers to interdisciplinary teaching in higher education, students report higher levels of cognitive though and greater knowledge of subject matter when they learn in interdisciplinary ways. This paper highlights interdepartmental collaboration for developing an undergraduate course integrating three concepts: child development, gardening, and nutrition. The course design is meant to prepare undergraduates for developmentally appropriate strategies to educate preschoolers on well-being through use of garden with edible crops. Forty-five students from various majors enrolled in the course over a 2.5-year period. Experiential learning activities included gardening activities at the University Child Development Laboratory along with tours of local farmers’ markets, the University Farm, and the Children’s Museum Edible Schoolyard. In reflective journaling, students reported on knowledge they gained in the three areas as a result of experiential gardening activities with preschoolers. The paper concludes with discussion implications of interdisciplinary course development among family science researchers and the role of gardening education in teaching health and well-being to preschoolers.
Are We Doing What is Best for the Children? Parenting Arrangements on Children's Outcome
Authors: Yaure Robin G. , Bartolic Silvia K.
Published: May 2022

In light of the growing research on family diversity, the field of family science has yet another critical topic to explore: the implications of family structures on children’s outcomes. With family policy and laws in many countries providing the option for shared parenting, this research on how children cope in different parenting arrangements comes at a necessary and opportune time. For this special issue, shared parenting is broadly defined as a collaborative arrangement regarding child custody where parental responsibilities for caregiving are shared by parents after divorce or separation occurs. Our first paper examines the co-parenting relationship following divorce with an emphasis on co-parenting support, overt, as well as covert conflict on child outcomes. Parental alienation is discussed in the following two papers – the first examining parental alienation in terms of contact time while the second extends this to an examination of parental alienation as a form of child abuse. The final paper in this set examines how parents make decisions about custody arrangements following divorce through an exchange theory framework.

Цель работы. В статье показана история развития традиционного домашнего ремесла и торговли у гуцул–даргинцев, в которой отразились природные условия края, хозяйственная деятельность, межэтнические связи, многовековые культурные традиции народов, которые в ряде случаев резко повышали экономическое значение промысловой деятельности. В ней дается развернутая характеристика художественных промыслов и торговли этого известного центра, и прежде всего камнерезному искусству. В конце ХIХ века изделия гуцул-даргинских мастеров имели хороший сбыт, так как через Чираг проходили караванные пути, соединяющие через горы Северный Кавказ, Южный Дагестан, Азербайджан, Армению с русскими казаками, жившими на Северном Кавказе. Перевал «Какма-даг» соединял федеральную дорогу государственного значения Мамраш – Ташкапур. Методы исследования. В результате использовался метод сравнительно-исторического анализа и установлена кризисная ситуация, складывающаяся в ремесле и торговле в Гуцул-Дарго. В качестве информационной базы исследования были использованы данные археологии и историко-этнографические материалы, собранные в Гуцул-Дарго, позволяющие выработать концептуальные подходы к проблемам возрождения традиционных ремесел и торговли. Результаты. Сформированы основные проблемы действующего механизма по возрождению ремесел и определены направления их возрождения. Область применения результатов. Для адекватного решения этого вопроса необходимо развивать ремесло и торговлю на базе надомного труда, а также путем организации таких школ-мастерских, как в Кубачах и Унцукуле. Выводы. Возрождение промыслов даст толчок развитию в Гуцул-Дарго целой цепочки сопряженных с ними видов деятельности: развитие туризма, сувенирных магазинов, дома отдыха, строительство кафе с национальной кухней и др. Все это, несомненно, будет способствовать сохранению народных промыслов и развитию горных сел.

Authors: Mussynov K. M. , Arinov B. K. , Abysheva G. T.
Published: May 2022

The results of a field experiment on the effect of microbiological and chemical plant protection agents on the productivity of camelina seeds are presented. The preparations (seed treatment before sowing was made with Extrasol, during vegetation - with insecticide Proteus and fungicide Pictor) were studied against the background of different sowing dates (15-20 May; 25-30 May). As a control, the version without the use of drugs was investigated. The field experiment was laid in quadruple repetition, the plot area was 63 m2. The seeding method is row seeding with a seeding rate of 6.0 million germinating seeds/ha. The forecrop is the 1st wheat after fallow. The work was carried out in 2018-2020 in the conditions of Northern Kazakhstan. The object of the study are the seeds and plantings of camelina Isilkulets variety. The soil of the site is chernozem, humus content - 2.50-3.89 %, nitrogen - 30.80-81.20 mg/kg, phosphorus - 11-30 mg/kg, potassium 620-770 mg/kg. The seeds were treated with Extrasol solution at the rate of 2 l (10 l of working solution)/t of seeds on the day of seeding. The optimal seeding date for camelina (May 25-30) and the optimal combination of preparations with seed treatment and spraying of crops with fungicide are recommended. The duration of the growing season of camelina in the conditions of Northern Kazakhstan was revealed, which averaged 72-81 days. High productivity was noted with the microbiological preparation Extrasol (seed treatment) and spraying of crops with fungicide Pictor (11.5-16.0 c/ha). A significant (LSD05 = 0.52) increase in seed yield was 0.77 t/ha. It was found that abundant rains during the growing season contribute to increased development and spread of diseases (fusariosis: R = 14.3-21.5 % and P = 27.5-86.4 %; alternariosis: R = 14.3-20.6 % and P = 25.2-84.3 %).

Authors: Nefedova E. V. , Shkil N. N.
Published: May 2022

The main etiological factor in endometritis is pathogenic and opportunistic pathogenic microflora entering the uterus during the postpartum period, during estrus, artificial insemination with contaminated sperm. A study was carried out to investigate changes in antibacterial sensitivity of microorganisms during therapy after labor purulent-catarrhal endometritis of cows with a preparation containing silver nanoparticles. To study the role of opportunistic pathogenic microflora in the etiology of postpartum purulent-catarrhal endometritis a clinical study of 150 cows in a farm in the Novosibirsk region during mass calving was carried out. Animals were divided into experimental and control groups according to the analogy principle. The control group received fish oil intramuscularly in a dose of 150 ml with oxytetracycline hydrochloride in a dose of 40 mg/kg of live weight once every 48 hours and uteroton intramuscularly in a dose of 10 ml once every 48 hours. The experimental group received intrauterine injections of argovit 10 % aqueous solution at a dose of 100 ml once every 48 h and uteroton intramuscularly at a dose of 10 ml once every 48 h. It was found that the treatment of postpartum purulent-catarrhal endometritis of cows with argovit decreased the average duration of treatment of the disease by 1.8 times compared to the preparation in the control group. When treating postpartum purulent-catarrhal endometritis of cows with argovit, an increase in antibiotic sensitivity of the isolated microflora to 21 drugs (87.5 %) from 1.2 to 100% was found. In the control group, there was a decrease in antibiotic sensitivity of the isolated microflora to 18 (75 %) preparations from - 1.1 to 28.7 %.

Authors: Thi Hang Nga Phan
Published: May 2022

With the global financial crisis in 2008, climate change, and the COVID-19 pandemic, most countries worldwide have re-thought their organization and operating models in their financial systems, including the banking system. In Vietnam, sustainable economic development has become an essential need in the long term. However, sustainable development requires a balance between economic growth and environmental protection. Therefore, Vietnam has chosen to develop a green economy, in which "green banks" have an essential role. Green banking is a future banking model that balances all stakeholders' economic and environmental benefits and costs in banking activities. Green banking emerges as an ideal model for future banking, a foundation for a green economy and sustainable development. Therefore, the article analyzes the current situation and some challenges to promoting the development of green banking in Vietnam and proposes policy recommendations to promote green banking development in Vietnam in the coming time. The article used methods to test the reliability of Cronbach's alpha scale, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and SEM to test the research hypotheses based on surveying 700 commercial bank managers and collecting data by a convenient sampling method from June 2021 to December 2021. Research novelty explores five factors affecting green bank development with a significance level of 1.0%. Finally, the author had policy implications for developing the green bank in the future. Doi: 10.28991/ESJ-2022-06-04-011 Full Text: PDF

Reusing heat dissipation in thermodynamic cycles is an exciting proposal to increase efficiency. In this paper, a two-stage ORC (Organic Rankine Cycle) is proposed to recover and reuse wasted energy from an SFGC (Single Flash Geothermal Cycle). The working fluids studied for the recovery system include R227ea and R116 and R124 and R125. The effect of the main elements of system performance is investigated using sensitivity analyses. Exergy degradation of various components is also calculated. For working fluids R227ea and R116, the thermal efficiency improved by 7.66%, from 0.2023 to 0.2178. The system's thermal efficiency is improved from 0.2023 to 0.2177 by 7.61% using R124 and R125. The exergy efficiency of the initial working fluid improves by 15.04%, from 0.5044 to 0.5803. Further, the second pair of working fluids from 0.5044 to 0.5852, which indicates a 16.01% system efficiency improvement. 85% of the system exergy is eliminated through the expansion valve, turbine 3, heat exchanger 2, and mixer. Including the recovery phase in the base, SFGC will positively affect the power plant's performance.

Palm Oil Mill Effluent (POME) merupakan salah satu limbah minyak kelapa sawit yang harus diolah karena dapat berakibat buruk terhadap lingkungan. POME memiliki kandungan gas rumah kaca yang cukup tinggi, yang  berkontribusi  terhadap pemanasan global. Saat ini, salah satu jalur pengelolaan POME adalah dengan mengolah POME menjadi biogas. Penelitian ini bertujuan untuk menghilangkan kandungan impurities biogas yaitu gas karbon  dioksida  (CO2) dan hidrogen sulfida (H2S) sehingga dapat menghasilkan gas metana (CH4) dengan kemunian yang tinggi. Penelitian ini dilakukan dengan mensimulasikan pemurniaan biogas menggunakan absorber packed column pada Aspen Hysys V.10 dengan menvariasikan debit air yg masuk pada absorber packed column serta komposisi awal pada biogas. Berdasarkan hasil penelitian diperoleh bahwa pemurnian biogas menggunakan air pada absorber packed column dapat meningkatkan kemurnian gas metana (CH4) pada biogas yang diikuti dengan meningkatkan debit air yang digunakan. Namun air yang digunakan sebagai pemurnian biogas juga dapat mengurangi kandungan gas karbon dioksida (CO2) dan gas hidrogen sulfida (H2S) dalam biogas karena kedua gas tersebut memiliki nilai kelarutan yang lebih tinggi dibandingkan dengan gas metana (CH4). Dimana kelarutan karbondioksida (CO2) dalam air 1,45 g/L dan kelarutan hidrogen sulfida (H2S) dalam air 4 g/L lebih tinggi ketimbang kelarutan metana (CH4) dalam air yaitu 0,035 g/L. Nilai HHV (High Heating Value) biogas meningkat dengan meningkatnya kemurnian dari gas metana pada biogas karena di dalam biogas, gas yang terkandung paling banyak adalah gas metana. Bertambahnya komposisi dari gas metana pada biogas diikuti dengan meningkatnya debit air yang digunakan pada absorber packed column. Sehingga, nilai HHV (High Heating Value) biogas dapat meningkat yang diikuti dengan meningkatnya kemurnian dari gas metana pada biogas.
THE SILTING UP OF VEGETABLE CROP AREA IN GANDIOLAIS (NORTHERN COAST OF SENEGAL)
Authors: F Diome , A. K. Tine , L Biaye
Published: May 2022

The Gandiolais is part of the large "Niayes" ecosystem in the Saint Louis region. It is bordered by active dunes from the recent Quaternary delimiting interdune depressions in which the sub-surface water table has favored the practice of vegetable crops. These vegetable cropping areas are production systems that are now facing silting up.

Our results show that this silting is due to deflation and/or mass movement of dune soils. These two phenomena are generated by the sensitivity of dune soils to deflation by trade winds and drought. The resulting negative consequences include, among others, the abandonment of vegetable cropping activities by farmers.

Solutions to reduce trade wind speeds and improve the cohesion and structuring of dune soils are proposed. In particular, we recommend the creation of windbreaks and the reconstitution of sufficient plant cover.

Anadolu coğrafyası lojistik bakımdan oldukça büyük bir potansiyele sahiptir. Çünkü Anadolu coğrafyası, Afrika'nın kuzeyinde, Avrupa'nın doğusunda ve Asya'nın batısında yer alan konumu ile oldukça stratejik bir noktadadır. Erken Ortaçağ’da
Anadolu çoğunlukla Bizans İmparatorluğu’nun hâkimiyetindedir. Bu sebeple Anadolu’nun lojistik altyapısını ve ticarete konu olan başlıca sanayi ürünlerini Bizans İmparatorluğu’nun penceresinden değerlendirmek gerekir. Başka bir
ifadeyle Erken Ortaçağ Anadolu’su Bizans’tan ayrı düşünülemez. Anadolu’da lojistik faaliyetler ve ticaret oldukça hareketlidir. Ancak Anadolu’daki hiçbir kent ticari bakımdan Konstantinopolis’ten ileri bir seviyede değildir. Dünya’nın
her yerinden insanlar ticaret yapmak için buraya gelmektedir. Ticari ürünler kapsamında Anadolu’da en çok tarımsal ürünler üretilmektedir. Kırsalda tarım sektörü yaygındır ve kentlerin gıda ihtiyacının çoğu kırsal kesimde üretilen
tarım ürünlerinden karşılanmaktadır. Anadolu’da sanayi ürünlerinin çoğu tarım ve hayvancılık sektöründen temin edilen hammadde ile üretilmektedir. Keten ve kenevir gibi endüstriyel bitkiler Anadolu’da mevcuttur. Bununla birlikte
ipek, Anadolu ticaretinde önemli bir yere sahiptir. Bunların dışında metal sanayi, el sanatları ve silah sanayi de Anadolu ticaretine konu olan önemli ürün başlıklarıdır.

This study aims to find: (1) the development of students' scientific reasoning abilities; (2) mental models developed by students in understanding the concept of dissolving weak acids and weak bases; and (3) the relationship between scientific reasoning abilities and mental models. The research approach is a descriptive study. The research subjects were 38 first-year students of the Chemical Education Study Program, Faculty of Teacher Training and Education, The University of Mataram. The research data collected were scientific reasoning ability data and student mental model data on the concept of dissolving weak acids and weak bases. Students' scientific reasoning ability was measured using the revised Classroom Test of Scientific Reasoning (CTSR) instrument in 2000, developed by Lawson and translated into Indonesian. The translation test has a reliability coefficient, calculated by the KR-20 formula, of 0.74. Identification of mental models using written tests and interviews. The content validity of the mental model test instruments is 94.2%. The data obtained were analyzed descriptively. The identification of mental models is made by using a constant comparative technique. The results showed a delay in developing students' scientific reasoning abilities compared to the criteria set by Lawson. Most of the students developed initial mental models in understanding dissolving weak acids and bases. In addition, the higher the student's scientific reasoning ability, the mental model developed tends to approach the scientific mental model.

Published: May 2022

A rubric is used for assessing student work and performance. It is a tool that works in various ways to develop student learning and has great possibilities. The study presented aims to investigate the rubric development of second language learners' argumentative writing. The study's significance is to explore how well the rubric assesses students' achievement of the skills needed to develop argumentative essays. This study will add to the literature more data regarding rubrics' effectiveness in providing constructive feedback to students. This research describes the results of the current study in relation to rubric feedback from undergraduate students and the faculty who teach them from a private university in Saudi Arabia. The use of the rubric would be to support instruction and student performance. The researchers have proposed a methodology to design, develop, and implement a rubric as a scoring guide for argumentative essays based upon the achievement of learning outcomes for this genre. The rubric was developed to evaluate the following criterion: organization, integrating academic sources, thesis statement, finding evidence/lack of evidence, writing refutation paragraph, writing counterclaims, content, academic tone, mechanic, and vocabulary. The researchers statistically found significant interrater reliability and convergent validity coefficients. The results are considered to encourage the evaluation and development of such rubrics to be used across universities and colleges.

Published: May 2022

Grounded in Social-Exchange Theory, the current study examines the association of self-sacrificial leadership with employees' knowledge sharing and knowledge-hiding behavior. Moreover, the mediatory role of employees' trust and intrinsic motivation was also investigated. The current study focused on self-sacrificial leadership outcomes while exploring underlying mechanisms to achieve those outcomes, specifically in SMEs in Indonesia. Using a longitudinal field survey, data were collected from 457 employees working at different levels in small and medium enterprises in Medan city, Indonesia. The results showed that self-sacrificial leadership was positively and significantly associated with the employees' knowledge-sharing behavior, while self-sacrificial leadership was negatively associated with employees' knowledge-hiding behavior. The results also revealed the interplay of employees' trust and intrinsic motivation between the link of self-sacrificial leadership and employees' knowledge sharing and knowledge hiding behaviors. Thus, it shows an exchange process of converting self-scarifying leaders' efforts into building trust among employees and intrinsically motivating them to share knowledge among peers and demotivate them from hiding knowledge.

"Under the Brixton Sun". Riflessioni su un antirazzismo di classe a 40 anni dai "riots" del 1981
Authors: Caroselli Andrea , Schiano Pasquale
Published: May 2022

Circa 40 anni fa, i riots di Brixton infiammarono le strade di Londra. Nonostante sia ricordata come una rivolta esclusivamente “nera”, essa rappresenta l’esito di un dialogo policulturale e “meticcio” tra la gioventù working-class che era andato sviluppandosi lungo gli anni Sessanta e Settanta. Ripercorrendo il cammino che ha condotto agli eventi, l’articolo mostra il modo in cui questo incontro ha preso forma nell’esperienza quotidiana e come possa aiutarci a superare limiti e contraddizioni dell’odierno antirazzismo istituzionale.
The spirit of place dynamics at GPIB Immanuel and the Pancaran Kasih in Depok
Authors: Damayanti Riajeng Sinta , Salura Purnama
Published: May 2022

This study discusses the spirit of place which is also known as the “genius loci” of two GPIB church buildings in Depok, Indonesia. It is important to note that the physical and spatial order of a structure theoretically has an expression usually interpreted according to the character and identity created by the observer or user. This means it is possible for buildings with the same function, liturgy, and space requirements but different physical arrangements to have the same spirit of place. The focus of this study is on the church of GPIB Immanuel and GPIB Pancaran Kasih in Depok and it was conducted qualitatively and descriptively through anatomical and phenomenological methods. The operational stage involves the emic steps which include field observations and structured or unstructured interviews for managers and informants doubling as the users of the buildings as well as ethical steps which are focused on the study of architectural theories. The results showed that the physical architectural order of the two churches creates a dynamic character and identity as well as a spirit of place even though they come from the same synod, order, and have the same liturgy and procession. This was discovered to be due to their similarities and differences.
The effect of building shape and orientation on energy use at sloped sites in tropical climates using sefaira
Authors: Notodipuro Priyanka G. A. S. K. W. , Mandala Ariani
Published: May 2022

One of the biggest contributors to energy usage are built infrastructures (up to 40%). Minimizing energy usage efficiently could reduce cost and give a better impact on the environment in terms of sustainability. As a tropical country that experiences sun exposure throughout the year, designing a building in Indonesia needs to respond to the impact of solar radiation inside the room for comfort and energy-saving effort. In addition, the topography of the site is considered throughout the process of designing a building, in which the site is located on sloped terrain (with a slant of 15 degrees celsius) and may influence the orientation and shape as it affects access to sunlight and view. This paper aims to identify which building orientation and shape of a project have the least energy usage during its preliminary phase on sloped terrains in tropical climate areas. 3 different building orientations (west-east, combination, North-east – South-west) and shapes are analyzed through experimental method by utilizing Sefaira as a plugin to Sketchup software using ASHRAE 90.1 - 2019 (ZONE 2) as material standard for the analysis. This research focuses on how a sloped site, as well as climate, affects building efficiency and how the orientation and shape of the building affect the building’s energy consumption. Difference in characteristics of the land, preferably regarding flat or sloped terrain lands, does not guarantee whether the energy usage will change, but it shows that sloped terrain sites could benefit on reducing the cooling load of a building as well as daylighting.

The increase in the frequency of cesarean section (CS) remains one of the actual problems of modern obstetrics and causes the concern to the world community. Today, it is believed that the abdominal delivery is a safer and more non-traumatic method of delivery for the benefit of the fetus than vaginal delivery. The relative number of cases of abdominal delivery, according to the WHO, should not exceed 10 % of the total number of births, which minimizes the occurrence of complications and prevents the development of bleeding and purulent-inflammatory diseases in the postpartum period. But the latest data demonstrate that this percentage is 18.6 % worldwide, that is one in five births ends in CS. The frequency of CS has been growing rapidly in recent years in most countries of the world, and in this context Ukraine is no exception (14.2 % in 2006, to 25.08 % in 2020). This increases the risk of maternal and perinatal morbidity and mortality. In the presented material for the distance learning about the operative delivery, doctors will find up-to-date information on indications, contraindications, methods of CS, as well as recommendations on counseling of pregnant women before surgery and preventive measures to minimize complications during obstetric surgery. According to the modern approach, the indications for the CS are divided into planned and urgent ones, which are clearly defined in this article. Considerable attention is paid to counseling of the patients before this operation and the obligatory acquaintance of the pregnant woman with the method of performing CS, anesthesia and potential perioperative complications and signing her the informed consent on the possible expansion of surgery. According to the standpoint of evidence-based medicine, the most optimal method of CS is presented, which significantly reduces the likelihood of hemorrhagic, purulent-inflammatory complications during surgery and in the postoperative period. The issues related to modern methods of anesthesia of CS with the use of multimodal analgesia, early mobilization of women in labor and prevention of thromboembolic complications, rehabilitation measures are also identified.
