BASIC PROVISIONS IN MODEL DEVELOPMENT IN THE CURRENT OF OPEN WATER STREAMS
Authors: Kochanenko Viktor , Aleksandrova Maria , Kondratenko Anatoly
Published: March 2021

For the design of hydraulic structures, it is necessary to use special methods for calculating the water flow to determine the kinetic energy acting on the structures. A mathematical model of a two-dimensional in terms of stationary open water flow and boundary conditions in the problem of free spreading are formulated. The main solved and to be solved problems of determining the flow parameters are determined, its reduction to a dimensionless form by various transformations of coordinates and flow parameters. The method proposed by I.A. Sherenkov. The solution of the problem is described, which depends on the dimensionless parameter - the Froude criterion at the outlet of the flow from the pipe. With Froude numbers exceeding one or close to it, it is required to build a series of graphs or develop a unified theory, an algorithm for solving the problem. The general conclusions on the work are as follows: - the need for further research has been proven theoretically and experimentally. - tasks are formulated that must be performed, solved in order to obtain a result adequate to the real process of solving the problem of free spreading of a turbulent flow to the entire spectrum of parameters. - substantiated the need to continue research to determine the entire spectrum of parameters of a stationary open two-dimensional potential flow in terms of its outflow from a free-flow pipe into a wide horizontal smooth channel. - the requirements for the model taking into account the conjugation of a uniform flow with a radial flow in the form of a simple wave are determined The work was written with a critical assessment of existing methods for solving the problem and to substantiate the relevance of further scientific research.

Published: March 2021

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has brought about additional challenges beyond the usual transitional stresses faced by a newly qualified doctor. We aimed to evaluate the impact of COVID-19 on interns’ stress, burnout, emotions, and implications on their training, while exploring their coping mechanisms and resilience levels.
Methods: Newly graduated doctors interning in a Paediatric department in Singapore, who experienced escalation of the pandemic from January to April 2020, were invited to participate. Participants completed the Perceived Stress Scale (PSS), Maslach’s Burnout Inventory (MBI), and Connor Davidson Resilience Scale 25-item (CD-RISC 25) pre-pandemic and 4 months into COVID-19. Group interviews were conducted to supplement the quantitative responses to achieve study aims.
Results: Response rate was 100% (n=10) for post-exposure questionnaires and group interviews. Despite working through the pandemic, interns’ stress levels were not increased, burnout remained low, while resilience remained high. Four themes emerged from the group interviews – the impacts of the pandemic on their psychology, duties, training, as well as protective mechanisms. Their responses, particularly the institutional mechanisms and individual coping strategies, enabled us to understand their unexpected low burnout and high resilience despite the pandemic.
Conclusion: This study demonstrated that it is possible to mitigate stress, burnout and preserve resilience of vulnerable healthcare workers such as interns amidst a pandemic. The study also validated a multifaceted approach that targets institutional, faculty as well as individual levels, can ensure the continued wellbeing of healthcare workers even in challenging times.

Authors: Roza Indra , Ananda Yussa , Siregar Lisa Adriana , Cahyadi Catra Indra , Junaidi Junaidi
Published: March 2021

Distribution transformer is a component in distributing electricity from distribution substations to consumers. Damage to distribution transformers causes continuity of customer service to be disrupted (power cut or blackout occurs). The length of the PLN electricity network requires a transformer to distribute electricity to serve consumers and how to maintain the transformer. The daily load curve of a peak load for housing, shops and factories / industries varies. Load served 200 kVA distribution transformer cannot serve the load on housing, shops and factories / industry. The method used is the replacement of a distribution transformer with a capacity of one stage greater or the replacement of a distribution transformer with a capacity of two levels larger. The distribution transformer carried out by the research is a capacity of 200 kVA replaced by 250 kVA. The ability of a distribution transformer cannot accommodate a load which will increase as an area is advanced. Observations made by calculating the age of the transformer by assuming the annual load growth (r) = 3% = 0.3. Annual peak load (P) = 1.8 p, u increase in oil temperature at peak load (θo = 96.21 0C; 84.16 0C). The increase in the hottest temperature above the oil cover, the increase in the temperature of the hottest place above the oil (θg = 20 0C; 20 0C). The ratio of the load loss to the nominal load excitation loss (Q = 3; 30). By assuming the values of these methods it can be estimated that the life of a distribution transformer is 20 kV, a capacity of 200 kVA is 18 years.
JOHN LOCKE: EL COLONIALISMO Y LA ESCLAVITUD. EL PROBLEMA DE LA PROPIEDAD PRIVADA ILIMITADA
Authors: Reyes Camargo Raúl
Published: March 2021

En este trabajo se sostiene que el colonialismo y la esclavitud están presentes en la obra de John Locke como elementos de su reflexión de filosofía política –principalmente en Two Treatises of Government y en The Fundamental Constitutions of Carolina–, y están suturados con el concepto clave de la “propiedad privada ilimitada”, la cual sólo es factible en la América de finales del siglo XVII. La propiedad privada ilimitada unida al derecho natural del hombre, se empata con la apropiación de las tierras americanas mediante el colonialismo, hecho completamente notificado a John Locke. Los nativos americanos y los esclavos traídos de las costas de África no eran considerados como personas, sino “propiedades” de los Señores propietarios. En la obra de Locke para apropiarse la tierra solo es necesario el trabajo. En contraste los esclavos, el núcleo laboral de las colonias, no podían poseer tierras al no ser considerados personas.

La interacción genotipo ambiente en cultivares de frijol común (Phaseolus vulgaris L.) y su reacción frente a Meloidogyne spp., son aspectos abordados a pesar de la influencia que tienen en los resultados productivos. Se determinó el potencial productivo de cinco cultivares de frijol común, en agroecosistemas de Pinar del Río, Cuba, y la incidencia de una población de Meloidogyne spp. en fase vegetativa del cultivo. Para ello se establecieron experimentos en ‘San Juan y Martínez’ y ‘Sandino’, sobre suelos Ferralítico amarillento y Fluvisol, respectivamente. Se emplearon los cultivares comerciales (tratamientos): ‘BAT 304’ (testigo de producción comercial), ‘CUL 156’, ‘Buenaventura’, ‘Delicias 364’ y ‘Chévere’. También se desarrolló un ensayo en condiciones semicontroladas con macetas de 1.5 kg y sustrato a base de suelo ferralítico amarillento + turba (70% + 30%), con y sin inoculación de Meloidogyne spp. (1.5 J2-huevos g-1 de sustrato) en los cultivares referidos. Las diferencias entre cultivares y su interacción con los agroecosistemas evidenciaron una marcada influencia sobre la producción de granos, aunque mejores resultados se obtuvieron con los cultivares ‘CUL 156’ y ‘Buenaventura’, pues superó en 25% el rendimiento del testigo de producción comercial, en el agroecosistema de ‘San Juan y Martínez’ y ‘Sandino’, respectivamente. Se confirmó que los cultivares evaluados son hospedantes de Meloidogyne spp., aunque ‘Buenaventura’ expresó menor índice de agallamiento para el nivel de inóculo empleado, mientras que la relación inversa entre fitomasa y el número de agallas y ootecas en el sistema radical de las plantas, sugirieron un efecto nocivo de estos fitonematodos en la fase vegetativa del cultivo.
Students’ Perceptions of an In-house Developed Multiplayer Online Role-playing Serious Game for Learning of 21st Century Skills – a Cross Sectional Study
Authors: Yap Kevin Yi-Lwern , Heng Tan Shawn Ignatius Boon , Yap Kai Zhen
Published: March 2021

ABSTRACT

Background:

An in-house serious game was developed to train pharmacy students in 21st century skills. Players work collaboratively in a “choose-your-own-adventure” format to find a cure for humankind in a post-apocalyptic fantasy world infested by zombies. Our objectives were to determine if the game would enhance student learning of 21st century skills in an engaging way, and whether the game could replace or supplement traditional teaching methods in the pharmacy professional skills training curriculum.

Methods:

A self-administered questionnaire obtained information about participants’ demographics, gaming interests, frequency, experiences and preferences; the game’s role in learning 21st century skills and its role in the curriculum. A pre- and post-quiz was conducted to test on participants’ pharmacy knowledge. Descriptive statistics, Friedman two-way ANOVA, Wilcoxon signed-rank test, and Mann-Whitney U test were used for analysis.

Results:

Participants preferred the three-dimensional first-person view, modern fantasy setting, authentic hero-adventure storyline, and the collaborative nature of gameplay. Majority felt that the game trained them on performing pharmaceutical calculations (27/30, 90.0%), patient history-taking and recommending appropriate medications (24/30, 80.0% each). Participants indicated that they learnt more about patient counselling (mean rank = 3.95) compared to the other 21st century skills, such as patient history-taking (mean rank = 3.02, p = 0.002), applying drug information from monographs (mean rank = 2.95, p = 0.003), pharmacotherapy of drugs (mean rank = 2.37, p < 0.001), and extemporaneous preparation skills (mean rank = 2.72, p = 0.001). Majority agreed that the game should not replace traditional methods of teaching in the curriculum (≥60.0%), but should supplement face-to-face counselling sessions (90.0%), extemporaneous/compounding labs (73.3%) and lectures (60.0%).

Conclusion:

Pharmacy students perceive that our game is able to train on 21st century skills, such as health communication (patient history taking and counselling) and performing pharmaceutical calculations. With appropriate implementation, this game has the potential to become a useful supplementary teaching tool to help enhance the learning achieved by pharmacy students.

Published: March 2021

Over the past few decades, climate change and the search for renewable energy sources have become hot topics within the research community. About 30% of the world's energy consumption is in the heating and cooling sector of residential buildings. Such materials can reduce the temperature variations, leading to an improvement in human comfort and decreasing at the same time the energy consumption of buildings. This paper assesses the integration of a microencapsulated phase change material (PCMs) with organic composite phase change as the core material and melamine-formaldehyde as the shell in hemp shive intended for building indoor wallboard. Paraffin waxes are cost-effective and have moderate thermal energy storage density but low thermal conductivity and, hence, require large surface area. Commercial manufactured organic PCM-S28 with a 25-29°C melting point received from MikroCaps Ltd. (Slovenia) has been used. The experimental boards were made using cold pressing technology and with 10% Kleiberit Urea Formaldehyde resin (UF) glue as a binding agent. The experimental boards were made 25 mm thick with a density of 310 ± 20 kg/m3 that qualify them as low-density boards. By adding 5% nanocapsules during the board manufacturing process, the heat capacity is increased by 28%.

Published: March 2021

The spatial and temporal capabilities of remote sensing data are very effective for monitoring the value of total suspended solids(TSS) in water using optical sensors. In this study,TSS observations were conductedin the westseason, transition season 1, east season, and transition season 2 in 2018 and 2019. Landsat 8 image data wereused,extracted into TSS values using a semi-analytic model developed in the Mahakam Delta, East Kalimantan, Indonesia. The TSS data obtained were then analysed for distribution patterns in each season. The sample points were randomly scattered throughout the study area. The TSS distribution pattern in the west season showeda high concentration spread over the coastal area to theoff sea, while the pattern in the east season only showeda high concentration inthecoastal areas. Transitional seasons1 and 2 showed different patterns of TSS distribution in 2018 and 2019, with more varied values. The distribution of TSS is strongly influenced by the season. Observation of each cluster resultedin the conclusion thathuman activity and the rainfall rate can affect the concentration of TSS.

Published: March 2021

Durante las últimas décadas la Asociación de las Naciones del Sudeste Asiático se ha consolidado como uno de los procesos de integración regional de mayor trascendencia, basta con solo detenerse a observar algunos datos macroeconómicos que demuestran la solidez que caracteriza a la quinta economía más grande del mundo. Las enormes complejidades que desconciertan al orden internacional condicionan a los países en desarrollo a desplegar un pragmatismo significativo que asegure una mayor interdependencia global. En este sentido, ante los factores geográficos y geopolíticos que limitan a la República Paraguay a un mayor crecimiento y desarrollo económico, resta indefectiblemente considerar los lineamientos de su política exterior, y de este modo, repensar su inserción económica en el Sudeste Asiático, apuntando principalmente a la diversificación de los mercados de exportación e internacionalización de las empresas locales. Las relaciones económicas, comerciales, diplomáticas y culturales con el conglomerado asiático resaltan por su exigüidad. Dentro de esta conjetura, este trabajo pretende abordar elementos endógenos y exógenos acerca de una mayor aproximación entre el Paraguay y los miembros de la ASEAN, para lo cual se profundiza la evolución de la integración regional asiática, las relaciones vigentes entre los socios de dicho bloque y el Paraguay, cuyos patrones estructurales son similares, en comparación a otras potencias asiáticas, y por último puntualizar la apuesta hacia una alianza estratégica que fortalezcan las relaciones internacionales del país guaraní.

Calprotectin is a calcium binding protein expressed at the inflammatory site by neutrophils and monocytes to activate the innate immune system. Thanks to this unique characteristic, it is a good indicator of local inflammation in chronic inflammatory rheumatism. All of the data highlight the key role that calprotectin plays in the inflammatory process in several inflammatory rheumatism. The value of serum and faecal calprotectin assays has been widely studied in recent years, in particular in rheumatoid arthritis, spondyloarthritis, juvenile idiopathic arthritis and vasculitis associated with ANCA but also for chronic inflammatory bowel disease. calprotectin has been identified as a powerful biomarker that allows the evaluation and monitoring of the activity of disease but also to predict structural evolution or response to treatment. Calprotectin is also a predictive biomarker of risk relapse. In this review, we discuss the value of calprotectin in chronic inflammatory affections as a diagnostic, potency or prognostic biomarker.

Abuse of antibiotics is more common in developing countries. This study was undertaken to investigate the presence of ciprofloxacin residue in broiler tissues and effects of antibiotics misuse on hematological parameters in broilers. Day old chicks (DOC) were collected and reared up to 31 days. The treatment was started from 16th day until sacrifice. On day 14th, the chicks were randomly divided into three groups namely control group (group A), discriminate antibiotic group (group B), and indiscriminate antibiotic group (group C). The control group was left untreated whereas, the discriminate group was treated with antibiotic, ciprofloxacin, followed by withdrawal period of one week. On the other hand antibiotic treatment was continued in the indiscriminate antibiotic group until the day of sacrifice, without maintaining withdrawal period. The mean body weight gain in treatment period (14 days) was the highest in discriminate group (1312± 26.1gm) followed by indiscriminate group (1089± 222.8gm) and control group (823.3±90.2gm). The Thin Layer Chromatography revealed that all the samples were positive in indiscriminate group with an exception of fat tissue (66.7%). The 50% liver and 33.3% kidney was ciprofloxacin positive in discriminate group and all others were negative. There was no positive sample in control group. . The hematological parameters such as Hb, PCV and TEC values of treatment groups showed significantly (p<0.05) lower, while PCV did not show any significant difference compared to the control group. Hence this experiment identifies the potential effects of ciprofloxacin misuse in broilers and their subsequent impacts on hemolytic system.

Aim: To determine the prevalence of malnutrition among HIV- infected under-five children and effect of highly active antiretroviral therapy (HAART) on the nutritional status. Method: This cross-sectional and descriptive study was conducted among under-fives presenting at the Paediatric HIV clinic in a tertiary centre in Nigeria. HIV positive children aged less than five years, who were on HAART and whose parents/caregivers gave consent were included. Odds ratios (ORs) and their 95% confidence intervals (CIs) were determined in a multivariate logistic regression analysis and p-values of <0.05 were considered significant. Result: A total of 92 HIV positive children comprising 52 (56.5%) males and 40 (43.5%) females were recruited, giving a ratio of 1.3:1. Children who were more than 48 months of age were (46.7%), while (9.8%) were aged 24 months or less. The mean age of the children was 44.5+12.9 months, while that of the male and female children were 43.9 +13.1 months and 45.2+12.6 months, respectively, and their age difference was statistically insignificant. The prevalence of undernutrition was 40.2% with a significantly higher proportion of them being male children (P= 0.02) while 1.1% of the children was overweight. The prevalence of severe wasting, severe underweight and severe stunting were 2.1, 3.3 and 17.4% respectively. A total of 12 (13.0%) were wasted, 14 (15.2%) were underweight, and 26 (28.3%) were stunted. Children who received HAART for more than 12 months were less likely to be wasted (P=0.02). Multivariate logistic regression also showed that being a male increased the risk of being underweight (OR=2.55, 95%CL=1.06-6.16) and stunted (OR=2.67, 95%CL=1.32-5.40). Conclusion: Malnutrition remains a problem of children living with HIV even while they are on HAART. The longer duration of HAART is significantly associated with better nutritional status.

Coronavirus, are belonging to the family Coronaviridae. Corona viruses have enveloped virions (virus particles) that measure approximately 120 nm (1 nm = 10−9 meter) in diameter. Coronaviridae is generally considered to contain two genera, Coronavirus and Torovirus. It was the first coronavirus to be isolated from domestic fowls in the late `known as SARS corona virus. COVID-19 is a disease caused by a new strain of corona virus. 'CO' stands for corona, 'VI' for virus, and 'D' for disease. Formerly, this disease was referred to as '2019 novel corona virus' or '2019-nCoV. Its origins have been traced to a food market in Wuhan, China, in December 2019.A virus apparently closely related to SARS corona virus. Symptoms begin 2 to 14 days after you come into contact with the virus. Early studies show that many people who have mild infections recover within 2 weeks. More severe cases tend to last 3 to 6 weeks. India is the fourth worst-hit nation by the pandemic after the US, Brazil and Russia. There’s currently no treatment specifically approved for COVID-19, and no cure for an infection, although treatments and vaccines are currently under study. Instead, treatment focuses on managing symptoms as the virus runs its course.

Artikkelissa tarkastellaan omaishoidon sopimuksellisuutta puheessa rakentuvana ilmiönä. Katse kiinnittyy siihen, millaista sopijuutta omaishoidon ohjaajat rakentavat haastattelupuheessa omaishoidontuen sopimusosapuolille. Aineistona on eri kuntien omaishoidon ohjauksessa työskentelevien 10 työntekijän haastattelut. Analyysimenetelmänä on käytetty diskurssianalyysiä. Analyysissa tarkastellaan, millaisilla selonteoilla omaishoidon ohjaajat sopimuksellisuudesta puhuvat ja millaista sopijuutta kielenkäytön avulla sopimusosapuolille rakennetaan. Kielellisen tarkastelun näkökulmasta omaishoitosopimus ei rakennu vain omaishoitajan ja omaishoidon ohjaajan väliseksi välineeksi, jolla sovitaan hoivanjaon ehdoista, vaan sopijuutta rakennetaan myös suhteessa yhteiskunnallisiin ja poliittisiin odotuksiin. Sopijuuden kautta esimerkiksi uusinnetaan kotihoidon ensisijaisuutta ja kuntien säästötavoitteita asiakaslähtöisyyden kustannuksella.

Published: March 2021

Для совершенствования технологии обработки почвы и применения удобрений в севооборотах в Республике Татарстан разработаны и освоены агротехнические приемы формирования обратногетерогенного строения пахотного слоя периодической заделкой органических удобрений, предварительно перемешанных с верхним слоем почвы, в нижнюю часть пахотного слоя. Для устранения подкисления почвы в удобрения добавляют 5 т/га извести, цеолитов и других органических веществ, которые обладают свойствами водных сорбентов. Глубина вспашки для заделки удобрений определяется глубиной пахотного слоя с припашкой 2 – 3 см подпахотного горизонта. Под последующие культуры севооборота проводят отвальную или безотвальную обработку почвы на глубину до нижней органической прослойки. Базисная часть технологии включает в себя создание и сохранение в течение всей ротации севооборота обогащенной органическим веществом прослойки в нижней части пахотного слоя, где разложение органики происходит преимущественно в анаэробных условиях. В надстроечной части технологии после глубокой заделки органики и мелиорантов периодически, 2 – 3 раза за ротацию севооборота, проводят припахивание к нижней унавоженной прослойке свежих органических удобрений, источником которых могут быть пласт многолетних трав, измельченная солома или сидерат.
