The work is devoted to the study of an oil-drop method for the production of spherical alumina used as a carrier for reforming catalysts with continuous regeneration. The mechanism of transformations occurring during spherical alumina forming by the oil-drop method from mixture of aluminum oxychloride and urotropin used as a gelling agent is proposed. The semi-quantitative composition of spheres after the neutralization stage is calculated on the basis of physicochemical methods of analysis. The possibility of obtaining spherical alumina with different physicochemical properties by varying temperature of the forming and neutralization stage is shown. Increasing the temperature of the neutralization stage leads to a narrower pore size distribution - the formation of more uniform pores with a smallercontribution of pores with a diameter greater than 170 angstroms. The strength of the obtained alumina is significantly affected: the strength increases several times with increasing the temperature of the neutralization stage.
The Role of Colloidal Particles in the Effect Of Electromagnetic Fields and Shear Stresses on the Viscosity and Filtration of Oil and Water
Authors:   Oil and Gas Research Institute of RAS, Lesin V. I.
Published: April 2024

The similarity of the results of exposure to an electromagnetic field, shear stresses, pressure fluctuations, for example, on the viscosity of oil, the rate of growth of paraffin deposits, the rate of growth of Ca/Mg carbonates deposits suggests that such results are the result of the same primary changes in the colloidal components of these systems.Based on the analysis of experimental data, it is shown that the results of such impacts can be explained by the destruction of colloidal aggregates of fractal structure consisting of colloidal particles of different material composition.Due to presence of magnetic and/or electrically charged metal oxides particles in fractal aggregates it make to be possible to split aggregates into separate fragments by applying electromagnetic fields. The particles in suchstructures are interconnected by such weak forces of electric and magnetic origin that the destruction of aggregates occurs even at small values of the fluid velocity gradients corresponding to small values of shear stresses.

The paper presents a numerical study of the original design of the rotary pulsating apparatus (RPA). In comparison with the traditional geometry, the simulation of a combined channel consisting of a narrowing section of the rotor and a diverging stator was performed for the first time. The results of numerical simulation of the RPA operation without additional inlet pressure in a wide range of rotor speeds are presented. Distributions of static pstat and total ptot pressure are obtained. The points of extremes and patterns of their changes are revealed. The length of the cavitation cavity in the RPA channel is determined, the equations of dependence. The cavitation characteristics of the RPA were evaluated. The distribution of the volume fraction of the vapor phase and the mathematical dependenceof the maximum value of the vapor phase on the frequency with equal pressures at the inlet and outlet are obtained.

Authors: Goe Xian Jeff  , Sharifah Najwa Syed Mohamad  , Siti Noorfaezah Abdul Kadir  , Syed Hussein Barakbah
Published: April 2024

Idiopathic intracranial hypertension (IIH), also known as pseudotumour cerebri, has an estimated incidence of 1 to 2 in 100,000 people per year. IIH commonly affects obese young women, where its pathogenesis, however, is not clearly understood. Patients present to the emergency department with a wide array of presentations. In light of this, we present a case of isolated sixth cranial nerve palsy in a non-obese young woman due to IIH in which brain imaging studies showed no abnormality; however, lumbar puncture reveals an opening pressure of more than 50  cmH2O. This case would help to alert physicians to consider IIH as one of the differential diagnoses when encountering such cases, as an uncommon presentation in the non-obese patient, and prompt referral is important to avoid unnecessary delay in the treatment of IIH.
The State of Health Supplements Consumption in Malaysia
Authors: Awang Rozaimie  , Vivien Yi Mian Jong
Published: April 2024

The demand for health supplements (HS) has skyrocketed in Malaysia and around the world in recent years. The demand for supplements keeps rising as more people show an interest in maintaining their health. Vitamins, minerals, nutritional supplements, and herbal supplements (botanicals) are popular health items. These medications are available over the counter and often come in pills, powder, or liquid form. The endemic effect of COVID-19 anticipates that people will look outside of vaccines for HSs to support their body’s immune system. The study investigates the Malaysian public’s awareness, consumption, and perception or belief about HSs, especially the antecedents to the reason for consuming HS. Purposive sampling and snowball methods were used to solicit data from the Malaysian public by employing a self-administered questionnaire in this cross-sectional online survey. Note that 478 responses were received, but 418 were usable (yielding an 87.45% response rate). The key findings demonstrated a statistically significant chi-square where there are positive associations between the antecedents of Malaysians consuming HS, including country of origin, the Internet, liquid form of HS, and loss of body fat, with a strong magnitude of association. The findings in this study provide a valuable indicator for scientists, researchers, producers, sellers, and marketers to identify the marketability of their invented HS products.

Published: April 2024

The purpose of this paper is to review the new management policy in medical imaging of the Covid-19 post-pandemic transition. This paper discussed the Standard Operating Procedure (SOP) introduced by the Ministry of Health (MoH) Malaysia to prevent and control intrahospital transmissions of Covid-19. A conceptual framework is proposed to highlight the key areas in the national SOP for preventing Covid-19 intrahospital transmissions in the radiology department. The key areas were classified into four categories: planned requests (patient appointments), (ii) open-access management (walk-in patient workflow and the triage system), (iii) direct contact (during radiology procedures), and (iv) exit policy and disinfection (post imaging conduct). The paper ends with a summary of diagnostic imaging classifications based on chest radiographs (CXR) and Computed Tomography (CT) images of suspected and confirmed Covid-19 patients. The Covid-19 SOP for the radiology department by the MoH was found to retain most of the patient quarantine and isolation guidelines by the Centre for Disease Control and Prevention (CDC) and incorporated several international policies on patient triage and disinfection of radiological equipment. The majority of the SOP is also sustained, like the SOP during the pandemic, except for the SOP that has been proven to be insignificant by recent research. The Covid-19 SOP for the radiology department plays an important role in reducing the intrahospital spread of Covid-19, with some areas needing improvement. Health workers in the radiology department should continue implementing the Covid-19 SOP and increase their knowledge in identifying Covid-19 signs on radiographic images to help safeguard themselves and the patients from intrahospital transmissions.

С использованием инструментально-аппаратных средств фиксации амплитуд виброускорений разработана методика экспериментального исследования вынужденных изгибных колебаний консольно закрепленного стержня-полосы, соединенного на одной из лицевых поверхностей с опорным элементом на участке закрепления конечных размеров, при действии осевой гармонической силы, приложенной на торце закрепленного участка. Построена уточненная модель деформирования закрепленного участка на основе уточненной сдвиговой модели С.П. Тимошенко с учетом деформаций поперечного обжатия и заданных перемещений опорного элемента. Процесс деформирования незакрепленной (консольной) части стержня описывается классической моделью Кирхгофа-Лява. Сформулированы кинематические условия сопряжения закрепленной и незакрепленной частей стержня. С учетом данных условий на основе вариационного уравнения Гамильтона-Остроградского получены уравнения движения незакрепленной и закрепленной частей стержня-полосы, соответствующие им граничные условия, а также силовые условия сопряжения закрепленного и незакрепленного участков стержня. Найдено точное аналитическое решение задачи о вынужденных колебаниях стержня при нагружении его гармонической осевой силой, приложенной к торцевому сечению закрепленного участка, а также гармонической поперечной силой на конце незакрепленного участка. Проведены вычислительные эксперименты для стержня-полосы, выполненного из алюминиевого сплава Д16АТ с учетом заданных перемещений опорного элемента в виде стального швеллера. Установлено, что при действии осевой силы, приложенной на торце закрепленного участка, колебания незакрепленной части стержня практически полностью определяются заданными перемещениями опорного элемента, а при действии внешней поперечной силы на конце незакрепленной части - практически не зависят от них.

Для определения упругих и прочностных характеристик полимерных композитных материалов при сдвиге как в плоскости армирования, так и в трансверсальном направлении используются различные экспериментальные методики, основанные, в частности, на растяжении образца-полоски под углом 45o к направлению армирования, трехточечном изгибе балочного образца с разным отношением пролета к толщине, изгибе короткой балки или сдвиге образца с V-образными надрезами. В этих методиках достаточно сложно оценить влияние на результаты испытаний таких факторов, как разворот волокон, сложное напряженное состояние в рабочей части образцов, степень анизотропии и локальные контактные деформации. В связи с этим в данной работе было проведено комплексное исследование по оценке упругих и прочностных сдвиговых характеристик тканевого углепластика по отмеченным выше методикам. Анализ результатов показал, что испытания образцов Иосипеску на сдвиг в плоскости армирования и испытания образцов-полосок на растяжение под углом 45o к направлению армирования дают практически одинаковые значения сдвиговых характеристик, но лишь в диапазоне деформаций, ограниченном величиной 5-6%. Деформации разрушения при сдвиге в этих экспериментах существенно различаются: растяжение образцов-полосок даёт на 30% меньшие значения. Также было установлено, что, несмотря на различия в способах деформирования при испытаниях образцов Иосипеску на сдвиг в трансверсальном направлении и испытаниях на изгиб балочных образцов, значения упругих и прочностных сдвиговых характеристик тканевых углепластиков отличаются незначительно.

Исследован изгиб трехслойной пластины при прямом и повторном знакопеременном нагружении круговой погонной нагрузкой. Физические уравнения состояния для материалов тонких внешних несущих слоев, учитывают возникающие малые упругопластические деформации. Материал более толстого жесткого заполнителя нелинейно упругий. Предполагается, что деформирование несимметричной по толщине пластины подчиняется гипотезам Кирхгофа в несущих слоях и гипотезе Тимошенко в заполнителе. Это приводит к линейному распределению радиальных перемещений по толщине слоев. Пластина подвержена воздействию теплового потока, падающего перпендикулярно ее верхнему слою. Торец пластины и наружная поверхность нижнего несущего слоя теплоизолированы. Для расчета температурного поля используется формула, полученная методом усреднения теплофизических характеристик по толщине пакета. Учтено влияние температуры на модули упругости и функции пластичности и физической нелинейности материалов. Постановка краевой задачи проведена вариационными методами. Получена соответствующая система уравнений равновесия и силовые граничные условия для рассматриваемой трехслойной пластины. В заполнителе принята во внимание работа тангенциальных напряжений. Сформулированы кинематические граничные условия и использована ограниченность решения в центре пластины. При построении решения задачи об изгибе соответствующей упругой пластины погонной нагрузкой использовано известное решение в случае равномерно распределенной кольцевой нагрузки. Применен предельный переход при толщине кольца нагрузки, стремящегося к нулю. Решение краевой задачи о нагружении упругопластической пластины из естественного состояния проведено методом упругих решений Ильюшина. Аналитическое итерационное решение выписано в функциях Бесселя. При повторном знакопеременном нагружении использована теория переменного нагружения Москвитина. В несущих слоях учтено циклическое упрочнение материала. Проведен численный анализ полученных аналитических решений, исследована зависимость перемещений от физически нелинейных свойств материалов слоев, температуры, граничных условий.
El Ecuador y el neoliberalismo: una aproximación a los desafíos político-culturales desde el progresismo
Authors: Vivanco Ordoñez Pablo
Published: April 2024

El Ecuador ha tenido sucesivos gobiernos de orden neoliberal, que han garantizado electoralemente su presencia en el manejo del Estado, aun cuando sufrieron un desgaste político e ideológico. El artículo indaga en las formas y dimensiones que adquiere el neoliberalismo en todas las esferas de la vida cotidiana, y cómo eso ayuda a explicar el triunfo de Daniel Noboa luego del fracaso de Guillermo Lasso, ambos al interior de una misma tendencia. Posterior a ello, se hace una revisión de lo sucedido en los últimos procesos electorales de Ecuador, problematizando la necesidad de movimientos sociales que robustezcan al progresismo. Además, plantea algunas aproximaciones para una discusión desde lo político-cultural como campo de disputa de los sentidos, y como espacio generador de significados y representaciones del mundo.
Gobierno de Gabriel Boric y el progresismo en Chile: reflexiones sobre su tendencia socialista democrática y desafíos ideológicos
Authors: Bustamante Olguín Fabian
Published: April 2024

El gobierno presidido por Gabriel Boric se adscribe a una tendencia socialista democrática que se caracteriza por combinar una economía de mercado regulada con políticas sociales sólidas, manteniendo la continuidad de políticas de centroizquierda desde la Concertación en 1990. A pesar del persistente neoliberalismo desde la dictadura, la élite económica chilena conserva su influencia sin fracturas aparentes. Boric, a pesar de su inclinación progresista, ha designado a figuras con conexiones empresariales, indicando la continuidad del enfoque neoliberal. El gobierno ha implementado diversas medidas sociales, como la reducción de la jornada laboral, la creación del Fondo Universal de Salud, la reducción de listas de espera y reformas en pensiones. Además, se ha propuesto una estrategia nacional para el litio, con la renegociación de contratos y la creación de un instituto de investigación. En cuanto a las izquierdas chilenas, se observa una falta de un proyecto alternativo sólido para superar el capitalismo, incluso en países autodenominados socialistas. En el caso de Boric, su gobierno se orienta hacia reformas y ajustes para mitigar desigualdades, en lugar de una superación total del sistema. Se destaca la prevalencia de políticas de identidad, enfocándose en demandas específicas en lugar de una perspectiva universal, generando debates sobre la cohesión del progresismo. En este contexto, la administración Boric se presenta como un liderazgo pragmático, consciente de la necesidad de revitalizar la izquierda política, aunque aún no logra consolidar una alternativa al sistema capitalista.

However, the question arises about the maneuvering room of these governments. While they share a critical stance against neoliberalism and seek to implement public policies that transform the socio-economic structures of the region, they face a series of challenges that we can summarize into three major ones: Adverse international context. The global economic crisis, the war in Ukraine, and the rise of the right in some countries around the world create a complex scenario for the implementation of progressive agendas. Existing power structures. Traditional economic and political elites still wield great power in the region, which can hinder the implementation of deep reforms. Institutional weaknesses. Corruption, lack of transparency, and the weakness of the rule of law are obstacles that limit the governments' ability to act. The debate on the future of the left in Latin America is complex and still open. While the current outlook is hopeful, it is important to consider the challenges faced by progressive governments. Their success will depend on their ability to build social consensus, strengthen institutions, and navigate in an adverse international context.

Published: April 2024

Maataloudella on keskeinen rooli ilmastonmuutoksen hillinnässä ja siihen sopeutumisessa Etelä-Pohjanmaalla, koska merkittävä osa suomalaisesta ruoasta tuotetaan maakunnassa. Maatalouden suhteellisen suurista alueellisista päästöistä huolimatta toimialalla voidaan tehdä myös hiilinieluja tukevia toimia, joiden avulla merkittävä määrä hiilidioksidia sitoutuu takaisin maaperään. Hiilinieluja voidaan lisätä hyödyntämällä muun muassa oikeanlaisia viljelymenetelmiä ja -tekniikoita. Ilmastotoimiin kohdistuvilla tukitoimilla ja kannattavuuskysymyksillä on suuri vaikutus ilmastotavoitteiden saavuttamisessa, mutta kokonaiskuvaan vaikuttavat myös maatalousyrittäjien toimintakulttuuri, asenteet ja arvot. Tämä on tärkeä huomioida, sillä ilmastotoimilla saattaa olla sekä myönteisiä että kielteisiä vaikutuksia esimerkiksi maatilojen kannattavuuteen ja tiloihin kohdistuviin asenteisiin. Kirjallisuudessa näitä sosioekonomisia vaikutuksia alueellisessa kontekstissa on tutkittu vasta hyvin vähän. Tämän esityksen tarkoituksena on taustoittaa eteläpohjalaisten viljelijöiden kokemuksia ilmastotoimista. Kartoitusta varten kerättiin aineisto hankkeissa tuotetusta aineistosta sekä viljelijöiltä, jotka ovat toimineet Tulevaisuuden ilmastoviisas maataloustuotanto Etelä-Pohjanmaalla (TIME) ja Ilmastosoturit -hankkeiden pilottitiloina. Aineiston pohjalta analysoitiin ilmastonmuutoksen hillintään liittyvien maatalouden toimien sosioekonomisia vaikutuksia alueella. Tulosten perusteella on laadittu suositukset jatkotutkimukseen sekä ilmastotoimien kielteisten sosioekonomisten vaikutusten vähentämiseen.
Path planning in advance to help with agricultural emissions and time management
Authors: Sarvela Konsta , Kalmari Janne , Haapala Hannu
Published: April 2024

Regardless of the job, the saying 'well planned is half done' holds true. It is well known that in Finland, the agricultural season in spring and autumn is short and there is no extra time to spare. Therefore, it is good to prepare and plan the work in advance. Autopilot has been available for work machines for about ten years, but route planning programs are just making their entrance. Autopilot in itself does not save time unless it is more precise than a human or follows a faster route. With RTK correction, centimeter-accurate steering is achieved, which eliminates overlapping driving, but the routes can still be suboptimal. In the Smart Agriculture project in Tarvaala, we compared how much time is saved by pre-optimized driving routes compared to manually driven ones. The routes were created in the spring, outside the season, and on the conventional side, the same paths as always were driven, meaning the longest possible swath. The work phase was sowing and fertilization, and the plot was a rectangular 8-hectare block belonging to the project. The work phases were recorded in a task file, and from both halves, all breaks over 30 seconds, which we assumed were due to human reasons such as breaks and machine checks, were removed. The experiment revealed that the time saved by pre-created routes was 17% compared to the traditional way of driving. The field was familiar to the driver in advance. Even if one considers the time spent creating the routes, about 10 minutes, the savings are regained the following year when the routes do not change, as long as the field remains the same shape. Different routes can, of course, be created for different work phases, such as sowing routes at a 45-degree angle to the sowing tillage. Temporal savings also bring other benefits such as lower emissions through reduced total consumption and improved driver well-being through reduced working hours.
Reciprocal extrachromosomal inheritance in barley: the transmission of an infective element through male and female gametes
Authors: Ahokas Hannu
Published: April 2024

My backcross pollinations of 53 spontaneum barleys recurrently with cv. ‘Adorra’ resulted in a maternally inherited, partial spike fertility case assigned “58”. Abnormal kernels, embryos and pollen, triploidy, miniature and streaked plants were among other symptoms. The 58-element greatly enhanced expression of the P-43 multi-ovary mutant in cv. ‘Paavo’. Cv. ‘Sudan’ was a dominant 58-sterility enhancer. Pollinating of lymegrass with 58-barley resulted in lymegrass monoploids, in which 58-specific DNA was not detected. The 58-Adorra usually showed increased RNA levels and RdRp activities. Germinating in ribavirin and in etoricoxib reduced the 58-sterility. Transfections of the shoot apexes of embryos with deproteinized 58-nucleic acids did not result in infection. Any plasmid or virus explaining the 58-symptoms could not be detected. Electrophoresed germ proteins showed a glycosylated protein in 58-Adorra (Mr approximately 78.000) not observed in Adorra. The 58-element has features of a prion. The fallout from the Soviet Chernobyl brought hot particle radioactivity to Finland before the 1986 spring sowing, and impaired this study intensively going on between 1982 and 1989.

Speaking skills are generally perceived as the measurement of the success of English Language Teaching (ELT), yet these skills are considered very hard to achieve. In fact, there have been different levels of speaking proficiencies among students. Therefore, the purpose of this study was to investigate the oral production learning strategies used by high and low proficiency English Education students. The design of this study was descriptive qualitative. Ten third semester English Education students of Universitas PGRI Kanjuruhan Malang were included. In collecting the data, the researchers used three instruments, especially a speaking test, documentation, questionnaires, and interview. The results show that the students with high speaking proficiency have higher motivation and use all kinds of strategies in the same frequency. Meanwhile, the students with low speaking proficiency use metacognitive, cognitive, and memory strategies. However, they did not use these strategies with the same frequency, where the lowest percentage of strategies used were affective and compensatory. The results suggest that students should choose learning strategies based on their needs. Students should use all learning strategies to improve their speaking skills. The implications and suggestions of the research are also discussed.

Published: April 2024

With the new Integrated National Dental Board Examination on the horizon, we are actively working to prepare our second-year students to incorporate and translate medical knowledge into clinical dental contexts. This way of teaching is a new adaptation for our dental school curriculum, and through the creation of the novel D2 Body and Disease Course, we are working to achieve this goal. We will share our experiences with the course and discuss how the global pandemic has affected our content delivery in both positive and challenging ways.
Recreating the Clinical Competency in the Zoom World of the COVID-19 Pandemic
Authors: Fleisher Laurie
Published: April 2024

This virtual Clinic Competency allowed students to demonstrate their ability to meet the objectives outlined in the established rubric. The students exhibited their ability to recognize, diagnose, and discuss appropriate clinical interventions to most adequately address the proper diagnosis of the patient presented in their clinical scenario. The faculty-student interaction in this virtual assessment was successful in mirroring the interaction that would have occurred in a live patient competency setting. Of the 73 virtual assessments administered, four students had a critical error and needed to repeat the assessment. They were all successful in attaining competency in performing a second clinical scenario. Different learning styles may have had an impact on the students' performance on a virtual exam. Further study and modifications of our initial endeavor may prove this type of assessment plays a positive role within the teaching framework by expanding our ability to establish an additional methodology for case presentation and student evaluation. The pandemic highlighted the need for a more diverse range of assessment techniques.

Curriculum in the Time of COVID: The Old Woman and the 'C'
Authors: Schreiber Andrea
Published: April 2024

The Old Woman and the C was the title of a presentation to the NYU Dentistry faculty that introduced a plan for curriculum revision with the dual goals of integrating the foundational, clinical, and behavioral sciences and improving clinical efficiency while delivering on our mission to provide patient-centered care. It was a radical plan to improve patient care and the student's educational experiences, and redefine how competency at the College would be assessed. The pre-pandemic plan for ensuring an integrated curriculum and preparation of our students for the INBDE was, and continues to be, effectuated as planned despite all the course resequencing necessitated by the pandemic.
Student and Faculty Perceptions of Dental Education During the COVID-19 Pandemic
Authors: Lopez Elizabeth N
Published: April 2024

In fall 2020, the Academy of Distinguished Educators convened a working group to examine how the curriculum changes in response to COVID had affected the students and faculty at NYU Dentistry. The changes made to the dental and dental hygiene curricula to comply with University and local and federal guidelines were provided: 1) remote instruction 2) small group discussions 3) faculty office hours via Zoom 4) performing preclinical lab work remotely with equipment delivered to students at home 5) discussing clinical cases with faculty via Zoom prior to the student seeing patients face-to-face 6)taking exams remotely via ExamSoft. The working group sent out two similar surveys: one to instructors and one to students to gather the opinions of community members. Responses were collected in December 2020 and January 2021. A total of 248 people responded to the survey (74 faculty and 174 students). Students liked taking exams and attending lectures remotely via Zoom, but very much disliked doing preclinical work remotely. Faculty liked to discuss clinical cases remotely and to give lectures via Zoom and disliked remote exams. Students felt more positive than faculty about remote exams, while the reverse was true for Zoom breakout rooms and preclinical work done remotely. Both students and faculty members were anxious about how remote learning would affect the students' future clinical abilities. Finally, we asked students what they would like faculty to know about the student experiences in the pandemic. The most common student responses were that faculty members need to be proficient in the technology used (Zoom), and that they need the appropriate equipment (good microphones and cameras). Students also reported that they needed more engagement and interaction with faculty members and classmates, that communication among administration, faculty, and students should be improved, especially regarding schedule changes. Students don't feel that their voices are heard; they do feel that student mental health is declining as a result.
