ВИКОРИСТАННЯ МЕТОДУ КОНФОРМНИХ ВІДОБРАЖЕНЬ ДЛЯ КОНТРОЛЮ КАВІТАЦІЙНИХ ХАРАКТЕРИСТИК СТРУМИННОГО НАСОСА
Authors: Паневник Д. О.
Published: August 2023

Сучасні методи дослідження кавітаційних режимів експлуатації свердловинної ежекційної системи не враховують можливість її обертання в свердловині, внаслідок чого зменшується ефективність прогнозування режиму роботи струминного насоса. В роботі запропонований механізм визначення впливу обертання струминного насоса  на конфігурацію ліній течії змішуваних потоків за допомогою теорії плоских потенціальних потоків. Для побудови конфігурації ліній течії за заданим полем швидкостей застосовано метод конформного відображення, який полягає у відображенні області з відомим комплексним потенціалом на область течії з заданими границями. Границі областей робочого та інжектованого потоку  визначені відповідно до теорії струменів: на твердих поверхнях, які обмежують течію нормальна складова швидкості дорівнює нулю, а на вільних поверхнях модуль швидкості приймає постійні значення. Відповідно до розробленої автором математичної моделі наявність циркуляційної течії може бути врахована шляхом використання коефіцієнта нерівномірності розподілу поздовжніх швидкостей по перерізу робочого струменя. Обертання потоку за рахунок дії сил в’язкісного тертя змінює епюру поздовжніх швидкостей, що може бути враховано введенням у відому методику розрахунку коефіцієнта нерівномірності. Використовуючи відомі процедури визначення вигляду функцій в площинах комплексної змінної та змінної Жуковського отримана система рівнянь координат струменя в параметричній формі. Розвязок отриманої системи рівнянь дозволив отримати прямий зв'язок між координатами струменя. Координати траєкторії робочого струменя визначаються величиною діаметра робочої насадки струминного насоса, відстанню до камери змішування та нерівномірністю розподілу швидкостей в потоці, викликану обертанням ежекційної системи в свердловині. Зростання відстані між робочою насадкою та  камерою змішування струминного насоса викликає зменшення радіуса поширення струменя робочого потоку.

Published: August 2023

Промислове виробництво, військові дії, життєдіяльність населення та тварин спричиняють суттєвий вплив на навколишнє середовище. Відбуваються зміни екосистем, які часто несуть небезпеку для людей, і можуть бути незворотними. Для сталого розвитку необхідне розумне коригування політики в системі екологічної безпеки. Тому екологічні служби мають застосовувати комп’ютерні технології, інформаційне моделювання, інтелектуальні інформаційні системи з елементами штучного інтелекту.

Об’єтивне розуміння ситуації та процесів в екосистемах передбачає великі обсяги інформації, різноманітність інформаційних і математичних моделей, міждержавні договори та законодавство. Сьогодні екологічні служби переважно зайняті обліком викидів в атмосферу. Важливим представляється аналіз, прогнозування та розумні впливи на процеси в екосистемах в контексті антропогенної діяльності. Різне сприйняття цієї проблеми призводять до різних підходів, які призводять до різних результатів.

Наукові дослідження в галузі екологічної безпеки для екологічних служб головно зосереджені на вивченні та документуванні забрудненості навколишнього середовища, викидах промислового та побутового характеру. Менше уваги приділяється змінам, що зазнають екосистеми, а ще менше – інформаційному моделюванню для забезпечення діяльності адміністративних органів з метою впливу на суспільство для покращення стану довкілля. Тому інформаційне та математичне моделювання, прогнозування змін екосистем є актуальним.

Дослідження направлене на розвиток методів діагностування інформаційного забезпечення, розроблення інструментів об’єктивізації служб екологічного контролю у контексті концепції інформаційного моделювання та прогнозування. Запропоновано математичні моделі для покращення інформаційного забезпечення діяльності в розрізі розумних змін існуючих ситуацій екологічних і соціальних систем.

Рекомендується використовувати інформаційні моделі в діяльності екологічних служб з використання обчислювальної техніки як з метою професійної роботи, так і з метою діагностики стану. Як комплексний підхід запропоновано враховувати користь і ризики, що поєднує майбутні здобутки та можливі втрати від прийняття управлінського рішення. Дослідження базується на формалізації нечіткості, неточності, невизначеності стану та процесів екологічних і соціальних системах.

Процес прийняття рішення базується на нормуванні користі та ризиків за заданими альтернативами. Ці альтернативи враховують як загальноприйняті правила, міжнародні угоди та закони із законодавчими актами, так і закони природи. Це дає змогу врахувати багатогранність інформації екологічних служб та покращити ефективність їх діяльності для сталого розвитку і дозволить використовувати обчислювальну техніку для оброблення інформації, об’єктивності.

Математична модель може бути використана для створення інформаційної системи екологічних служб. Для її реалізації вистачить комп’ютера з посередніми обчислювальними можливостями для загального користування.

Multi-vector interstate interaction has led to increased cooperation in the social, economic and ecological sectors. The solution of new challenges facing society should be closely based on the development of innovative potential, which is primarily ensured by the development of education. Currently, the national and international labour markets have a demand for improved quality of education, increased requirements for the level of knowledge, competences and skills, and increased investment in human capital.One of the main tasks of the education system today is its modernisation, which contributes to increasing the accessibility of quality and efficiency of education. It is the development of academic mobility of students that largely contributes to the achievement of these goals. The main goal of mobility is to give students the opportunity to gain a variety of knowledge in their chosen field of study and to provide them with access to recognised knowledge centres.The article analyses the problems of student academic mobility in domestic and foreign research. Using the methods of generalisation and systematisation, the author presents various interpretations of the concept of "academic mobility" in the works of both domestic and foreign scholars and, as a result, establishes that academic mobility abroad is considered only as a transnational process or in the context of international mobility programmes. The social conditions for ensuring academic mobility are determined. The types of academic mobility are identified and characterised. As a result of the study, academic mobility of students is defined as a form of organisation of the educational process and is considered in the context of globalisation and internationalisation, and is also defined as one of the means of internationalisation of higher education, and international cooperation between educational institutions is one of the main criteria for assessing the work of a modern higher education institution

The article elucidates the peculiarities of the formation of the professional identity of future psychologists in the process of professional training of students in higher education institutions. On the basis of the conducted empirical research, the peculiarities of the dynamics of the formation of the most important indicators of the professional identity of future psychologists during their studies at higher education institutions were clarified, in particular, the differences that exist in the statuses of professional identity among junior and senior year students were established.Based on the conducted empirical research, it was established that the professional identity of junior psychology students is characterized by the beginning of understanding the essence of a psychologist's work, familiarization with its main functions. During this period, there is an entry into a new social and professional environment. The external student identity turns into an internally accepted, conscious, emotionally colored characteristic. This is an unstable stage associated with adaptation to the new social role of the student. Its essence lies in the formation of student identification (I am a student) and an unconscious fascination with the future professional identity.Senior years are characterized by the realization of a range of roles during professionalization, as well as the formation of new goals and perspectives. This is a period whose essence consists in rethinking and clarifying various options for professional and creative self-development, employment and building a professional career (I am my profession and career). This period can tentatively be called clarifying.

For this purpose, a total of 12 athletes between the ages of 18-20, who have been actively involved in archery for the last two years, took part in the study voluntarily. The mean age of the participants was 18.92±0.79 years, average height was 171.83±6.99 cm, body weight was 65.67±5.97 kg, BMI was 22.23±1.28. On different days, control application, experimental application foam roller 30 seconds, experimental application 60 seconds method with foam roller were applied to the subjects, immediately after, visual and auditory reaction test, balance and arrow shooting performance applications were made. In the control application, tests were applied to the subjects without any myofascial release protocol. The obtained data were analyzed in SPSS 22.0 program. In order to determine the difference between the applications, one-way analysis of variance and LSD tests were applied in repeated measurements. As a result of the statistical analysis, a significant difference was observed in favor of the experimental applications (30-60 seconds) compared to the control application in the visual and auditory reaction tests, balance and arrow shooting performance tests (p

La Organización Mundial de la Salud, en julio de 2022, declara a la viruela del mono como un problema público de salud por brotes epidémicos en países que no han reportado esta enfermedad previamente. Esta patología infecciosa es causada por uno de la familia orthopoxvirus, endémico de África central y occidental, que ha sido considerado relevante por ser el orthopoxvirus más importante internacionalmente. Actualmente, una detección rápida de la enfermedad es importante para control epidemiológico, y se realiza principalmente por técnicas moleculares de detección como: amplificación mediada por recombinasa (RPA), GeneXpert, PCR en tiempo real y amplificación isotérmica mediada por bucle (LAMP). El objetivo fue describir las técnicas moleculares usadas en el diagnóstico y estudio del virus de la viruela símica. Las pruebas de detección molecular, a pesar de ser distintas en su metodología, presentaron una alta sensibilidad y especificidad en la detección de los genes diana. Sin embargo, los estudios realizados en RPA, a pesar de que fueron rápidas con un tiempo entre 7 – 30 minutos, presentaron mejores límites de detección en relación a las otras pruebas y detectaron a los genes: G2R, G2L y la proteína de unión al factor de necrosis tumoral, sugiriendo una alta confiabilidad.

Abstract

Nugget is a processed meat products which mixed or without other ingredients and permitted food additives. In its manufacture, the nugget is formed and then steamed and fried before being consumed. One of the most widely grown horticultural crops in the Nagari Ladang Panjang area is corn. Corn can be used as nuggets which are rich in fiber and added tofu as its protein. The purpose of this activity is to provide knowledge to the community about making sweet corn-based nuggets. The results of the implementation of this service were successful in processing and the community was very enthusiastic. This corn nuggets product can be used as an alternative in consuming vegetable protein and fiber. If these corn nuggets are developed properly, they can become one of the superior products in the form of frozen food from Nagari Ladang Panjang.

Neostructural Realism’s Explanation on Russia-Ukraine War
Authors: Hakim Amri
Published: August 2023

This article aims to explain why NATO keeps expanse on Ukraine, and why Russia responses it through invasion now. By using qualitative methode, library research, and the neostructural realism theory founded that since the dissolution of Soviet Union, NATO has been no longer appropriate abstracted as an alliance but an unipole security coalition, then the NATO expansion on Ukraine can be seen as the continuity of U.S.’ containment policy to Russia, and adding its coalition partners for unilateral action legitimacy in order to maintain its hegemon position which undermine Russia’s Eurasia great power vision and its crucial national security. Meanwhile the uneven distribution of power elements between U.S. and Russia as the macro international structure constraint Russia invasion but  the bipolar world through Russia-China unlimited strategic partnership, and the shifting of U.S. offset strategy to Russia on hypersonic missile as the micro structure encourage Russia to take invasion now.

Introduction: There have been over 87 million cases of Coronavirus Disease 2019 (COVID-19) in the United States (US).

Objective: The objective of this study was to develop a novel questionnaire to assess risk perception of COVID-19 and xenophobic attitudes among adults in the US at the beginning of the pandemic.

Methods: An anonymous self-report questionnaire was developed for this study in February 2020, and was distributed using convenience sampling from March 10 to March 25, 2020. The questionnaire assessed knowledge and risk perceptions of COVID-19, as well as attitudes toward individuals of various races and ethnicities.

Results: 662 US adults completed the questionnaire. On a scale from 1 (low) to 5 (high), the mean risk perception was 3.44. Those with knowledge of COVID-19 and higher education levels reported higher risk perception and higher feelings of warmth towards Asian people. Forty percent of the sample had recently witnessed or experienced anti-Asian attitudes at the time of the survey. The majority of participants reported having heard about COVID-19 from news media, social media, and family or friends.

Conclusions: Our sample had a moderate level of risk perception, potentially due to the time period of data collection (i.e., early in the pandemic course). The results suggest that knowledge about COVID-19 informed perceived risk and affected willingness to engage in healthy protective behaviors. Our study provides historic context of how people perceived the virus at the beginning of the pandemic, and gives insight into the aftermaths regarding quarantine and attitudes towards Asian Americans.

pancreatic islets in which a process of programmed cell death (apoptosis) is elicited in the β-cells by interaction of activated T-cells and proinflammatory cytokines in the immune infiltrate. Interleukin-6 (IL-6) is a pleiotropic cytokine with a key impact on both immunoregulation and nonimmune events in many cell types .Objective: to assess the level of serum IL-6 as an inflammatory marker in type 1 diabetic children, with correlation to FBG and HbA1c.Subjects and methods: 45 type 1 diabetic child (20 males and 25 females), mean age 10.9± 3.4 years who attended the National Diabetic Center, Al-Mustansiria university were included in this study. 45 apparently healthy controls matched for age and sex were participated in this study .Fasting venous blood samples were collected from all the subjects. The serum was used for analyzing HbA1c, Fasting Blood Glucose (FBG) and IL-6, HbA1c was estimated by high performance liquid chromatography ,Serum glucose level was determined enzymatically and serum IL-6 was measured by enzyme linked immune sorbent assay.Analysis of data was performed using the statistically package for social science (SPSS) version 17.0.Results: Mean serum IL-6 level in type 1 diabetic children were significantly higher compared to the healthy controls (30.9 Pg/ml ±10.85versus 10.57 Pg/ml±1.98 (P ≤0.0001), and positive strong correlation was found between serum IL-6 and FBS, HbA1C ,BMI.Conclusion: There is a low-level of chronic inflammatory state in type 1 diabetic children reflected by the level of serum IL-6, that may play a key role in the early stages of atherogenesis and the development of microvascular complications.
Validity and reliability of CDAI in comparison to DAS28 in Iraqi patients with active rheumatoid arthritis
Authors: Gorial Faiq I.
Published: August 2023

Background: Rheumatoid arthritis (RA) disease activity plays a central role in causing disability both directly and via indirect effects mediated through joint damage. Evaluation of RA disease activity is therefore important to predict the outcome and effectiveness of therapeutic interventions during follow-up. Clinical disease activity index (CDAI) is new simple tool for measurement of disease activity.Objectives: To assess validity and reliability of CDAI in comparison to disease activity score-28 joints (DAS28) in Iraqi patients with active RA.Patients and Methods: Sixty nine Iraqi RA patients were included in this study. All patients were fulfilling the ACR classification criteria and active. Full history was taken and complete clinical examination was done for all patients. Patients’ age, sex, duration of the disease, number of tender joints, number of swollen joints, patient’s and physician’s (evaluator) global assessment by visual analogue scale (VAS) (0–10 cm) were recorded. Laboratory analysis included erythrocyte sedimentation rate (ESR). CDAI and DAS28 were measured to assess disease activity.Results: Of 69 patients included in this study, there were 58 women and 11 men. Mean age of the patients was 45.65±12.26 years and mean duration of disease was 7.75±7.85 years. Mean DAS28 and CDAI were 5.86±1.24 and 30.07±14.07respectively.There was direct significant correlation between CDAI and DAS28 (r= 0.879, P< 0.001). Also we found good agreement between CDAI and DAS28 (Kappa = 0.795, P < 0.001). CDAI had sensitivity 90%, specificity 92%, Likelihood ratio (LR) 45.67, Area under the curve (AUC) 0.983 [95% confidence interval (CI) 0.933-1.000] (P value < 0.001).Conclusions: CDAI is a valid and reliable measure for assessment of Iraqi patients with active RA in comparison to DAS28.
MS@Work in Flanders: The Development of a MS Toolkit for a Stable Employment

Published: August 2023

Persons with MS have the highest unemployment rates compared to other chronic diseases. We want to develop a MS Toolkit with several aids for persons with MS to help them gain a sustainable employment with sufficient and permanent attention and guidance for the daily obstacles in the workplace. Therefore, the opportunities and bottlenecks were mapped through a survey with persons with MS and employers, a diary and expert interviews. There were 3 major problems identified: Persons with MS find it difficult to ask for help in time; they have little or no concrete knowledge about who they can turn to for support and healthcare professionals do not always possess the expertise to guide their patients through problems experienced on the work floor. These problems were used as fundaments in a cocreation session to create the content of the MS Toolkit: a screening tool and dashboard. The screening tool ensures an annual reflection of the work situation. The dashboard links each problem to the most appropriate service.
Accessible Consumer Electronics Are Essential to Closing the Gap in Assistive Technology Provision
Authors: Banes David , Lobnig Sabine
Published: August 2023

According to the Global Report on Assistive Technology (2023) [1] more than 2.5 billion people require one or more assistive products – a number that is expected to grow to over 3.5 billion by 2050 due to the aging of our societies. Over the past decade, the design of products that empower people with a disability has shifted from specialized and dedicated products designed only for those with a disability to features and functions integrated into cost-effective consumer technologies for the benefit of all. The opportunity to expand the availability of such technologies is at risk of being ignored due to models of AT delivery that are founded in medical devices, and which have failed to reflect trends in our understanding of technology and the choices and preferences expressed by persons with a disability. This research suggests that such expansion offers significant benefits to people with a disability and better both economic and social return on investment for authorities.

Since there was no French tool adapted to the reality of people with autism enrolled in a work integration program in Quebec, we have modified the Profile of Rehabilitation and Adaptation in a Work Context for People with Intellectual Disabilities according to the scientific literature on autism. Content validity (n=17) and applicability (n=5) were done with success. Result is an Excel compiler containing 3 informative tabs, 10 tabs on the dimensions of work rehabilitation (59 items) and 4 tabs used to compile the results. Socio-professional practicians are welcomed to use this new tool to pursue construct and internal validity.
