Published: August 2021

The paper considers the application of SDN technology in 5G / IMT-2020 networks, namely, answers to the questions: What is SDN technology used for in 5G / IMT-2020 networks? How is SDN technology used in 5G / IMT-2020 networks? , What is the role of SDN technology in 5G / IMT-2020 networks ?, What are the functions of SDN technology in 5G / IMT-2020 networks? and the like. But before that, it describes what SDN is and what 5G / IMT-2020 is. The paper describes and analyzes the methods of using SDN technology in fifth generation networks in terms of the function and role that SDN plays in these networks. Usually in the literature, this information exists in a scattered form, and sometimes some methods of application are either very superficially described, or not described at all, or they are tied to other methods. The aim of the work is to identify and analyze well-established methods of using SDN in 5G / IMT-2020 networks. To identify SDN applications in 5G / IMT-2020 networks, SDN architecture, SDN benefits, overall 5G / IMT-2020 network architecture, 5G / IMT-2020 standards and requirements, network protocols were studied and analyzed 5G / IMT-2020, some existing and future likely 5G / IMT-2020 network services, general concepts of some future networks such as tactile internet, internet skills, model networks, etc. The paper provides a radial diagram of the ways (options) of using SDN in 5G / IMT-2020 and describes each option.

Schwarzschild black hole can also produce super-radiation phenomena and the cosmic censorship conjecture may be violated
Authors: Chen Wen-Xiang
Published: August 2021

This article points out that when the boundary conditions$\frac{T}{T_{c}}=z$ (when z is plural) are preset, bosons can produce Bose condensation without an energy layer. Under Bose condensation, the incident wave may condense in the Schwarzschild black hole. At that time, the Schwarzschild black hole event horizon Potential barriers can be generated nearby, and we think that Schwarzschild black holes can also generate superradiation phenomena(This article uses the natural unit system).This implies that the cosmic censorship conjecture may be violated.

Background: Breast cancer is the most common cancer in women which affects them emotionally and psychologically. The aim of this research was to examine emotional functioning and self-perception in post mastectomy women. Subjects and methods: This cross-sectional single-center study included 101 women with breast cancer one month and one year after mastectomy. It was conducted using anonymous questionnaires developed by the European Organization for Research and Treatment of Cancer (EORTC): EORTC Quality of Life questionnaire (QLO) - C 30 (version 3), questionnaire with breast cancer module EORTC QLQ BR-23 and a sociodemographic questionnaire.Results: Compared to results one month after mastectomy, in women one year after mastectomy there was significantly less tension (Mann-Whitney U test, p=0.011) and emotional irritability (Mann- Whitney U test, p=0.013), also the memory problems declined (Mann-Whitney U test, p=0.008). Discomfort with hair loss affected all parameters except concentration problems. The participants felt less physical attractive (p=0.647), were worried (p=0.645) and less feminine due to illness (p=0.638). A year after surgery there was no connection between anxiety and observed parameters. Conclusion: Breast cancer affects emotional functioning and self-perception of women especially in early postoperative period and during cancer treatment. A year after surgery there was no more connection between anxiety and hair loss discomfort. Patients need medical, social and psychological support during and after breast cancer treatment.
Vibration-based Multi-class Damage Detection and Localization Using Long Short-Term Memory (LSTM) Networks
Authors: Sony Sandeep , gamage Sunanda , sadhu Ayan , Samarabandu Jagath
Published: August 2021

In this paper, a novel method is proposed for detecting and localizing structural damage by classifying acceleration responses of a structure using a long short-term memory (LSTM) network. Windows of samples are extracted from acceleration responses in a novel data pre-processing pipeline, and an LSTM network is developed to classify the signals into multiple classes. A predicted classification of a signal by the LSTM network into one of the damage levels indicates a damage detection. Furthermore, multiple signals obtained from the vibration sensors placed on a structure are provided as input to the LSTM model, and the resulting predicted class probabilities are used to identify the locations with high probability of damage. The proposed method is validated on the experimental setup of the Qatar University Grandstand Simulator (QUGS) for binary classification, as well as, full-scale study of the Z24 bridge benchmark data for multi-class damage classification. Experiments show that the proposed LSTM-based method performs on par with 1D convolutional neural networks (1D CNN) on the QUGS dataset, and outperforms the 1D CNN on the Z24 dataset. The novelty of this study lies in the use of recurrent neural network based LSTM for vibration data for multi-class damage identification and localization.
Negative performance evaluation in the imposter phenomenon
Authors: Gadsby Stephen , Hohwy Jakob
Published: August 2021

The imposter phenomenon (IP) is associated with a bias towards negative evaluation of one’s own performances. This study employs an online problem-solving task to investigate this bias. Participants (graduate students from the UK, US, and Europe; n = 163) solved reasoning problems and subsequently evaluated their performance. Participants high in IP evaluated their performance more negatively than participants low in IP. This pattern was observed both during the task and after completion. It was also observed in objective assessments (estimates of accuracy) and comparative assessments (estimates of rank amongst participants). Performance evaluation bias was not associated with a bias in the selection of feedback about performance nor was it mediated by depression or self-esteem.
The relationship between habits and motor skills in humans
Authors: Du Yue , Krakauer John W. , Haith Adrian
Published: August 2021

How do habit and skill relate to one another? Among many traditions of habit research, we suggest that “slips-of-action” habits are the kind most likely to relate to motor skill. Habits are traditionally thought of as a property of behavior as a whole. We suggest, however, that habits are better understood at the level of underlying component computations and, at this level, habits can be considered equivalent to the phenomenon of automaticity in skill learning – improving speed of performance at the cost of flexibility. Lastly, we consider the importance of habits in learning complex tasks given limited cognitive resources and suggest that deliberate practice can be viewed as an iterative process of breaking and restructuring habits to improve performance.
Promoting allyship among South Asian and Arab Muslims toward Black and Latino/a Muslims in American Islamic centers
Authors: Pasha-Zaidi Nausheen , Warren Meg Aum , Ashmawi Yvonne Pilar El , Kowai-Bell Neneh
Published: August 2021

Increased social justice awareness in the United States and shifting demographics are giving birth to a more diverse and egalitarian generation. Improving relations across social categories has been a key topic in di-versity, equity, and inclusion work, but less emphasis has been placed on cross-racial allyship within mi-nority populations. While allyship in racial contexts is often perceived as a White versus non-White issue, this binary position erases the diversity that exists within communities of color. A dichotomous approach to allyship that positions White heterosexual males as the primary holders of privilege does not address the disparities that exist within and across minoritized communities. While Arabs and South Asians are minori-ties in the US on a macrolevel, they often hold privileged positions in Islamic centers and other Muslim spaces—even though Black Americans make up a larger percentage of the Muslim population. Additional-ly, there is an increasing number of Latino/a Muslims in the US, but they are often invisible in larger con-versations about Islam in America as well as in discourse among Muslim Americans. In this chapter, we explore the concept of allyship and how South Asian and Arab Muslims can support and advocate for Black and Latino/a Muslims in American Islamic centers. We also discuss Islamophobia in the US as well as the anti-Blackness and racism that exists within Muslim communities and provide suggestions on how Islamic centers can serve as spaces of allyship and cross-racial dialogue.
"I Believe AI Can Learn from the Error! Or Can It Not?": The Effects of Implicit Theories of Artificial Intelligence on Trust Repair of the Intelligent Agent
Authors: Kim Taenyun , Song Hayeon
Published: August 2021

After an intelligent agent makes an error, regaining lost trust is an important issue. In the process of trust repair, individuals' underlying perception of the potential for improvement in an intelligent agent and the way an agent apologizes may influence the agent's trust repair process. In this study, we investigated the influence of implicit theories of artificial intelligence and their apology style on trust repair after the trust violation. A 2 (implicit theory: Incremental vs. Entity) X 2 (apology attribution: Internal vs. External) between-subject design experiment was conducted (N = 150). Participants were asked to make 40 different decisions in a stock market investment game created for this study. Each time participants made an investment decision, an intelligent agent gave them a recommendation. The results show that trust was damaged less severely in the incremental rather than the entity theory condition and in the external rather than internal attribution apology condition after the trust violation. Trust was restored more strongly in the Entity-External condition than in the others. We discuss both theoretical and practical implications.

Published: August 2021

Introduction: Dental age estimation using orthopantomogram is very useful in pediatric dentistry, orthodontics in clinical diagnosis and treatment planning and also has forensic application. Demirjian method is widely used for age estimation and Willems method has been suggested to be accurate than Demirjian in various populations. To estimate the dental age of children in a specific population of Nepal by Demirjian and Willems method, compare them with the chronological age and assess their applicability.
Materials and Method: Digital orthopantomograms of 5 to 14 years of children were used to estimate the dental age by Demirjian’s 7- teeth method and Willems method. Descriptive statistics was used and mean with standard deviation was calculated for gender and age of the samples. Paired t-test was used for comparison of chronological age with dental age. P < 0.05 was considered as statistically significant.Pearson correlation was used to assess the correlation between chronological and dental age in both the genders.
Result: By Demirjian method, there was an underestimation of 0.276 years in males and 0.194 in females and by Willems method, 0.652 in males and 0.847 in females which were statistically significant. There was an underestimation of dental age in all the age groups except in the age group of 5,7 and 14 for Demirjian age which was statistically nonsignificant. Pearson correlation demonstrated strong positive correlation between chronological age and dental age.
Conclusion: The underestimation of dental age was more by Willems method as compared to Demirjian method. There was a strong positive relationship between chronological age and dental age in both the genders. Demirjian’s 7- teeth method was more applicable as compared to Willems method when tested in selected Nepalese children population

Optimization of construction site layout using dynamic hybrid bacterial and ant colony algorithm
Authors: Son Pham Vu Hong
Published: August 2021

The efficient plan of site arrangement during the construction phase has been considered a vital duty to successful project performance due to the productivity enhancement as well as safety in executions. The optimization of the Construction Site Layout Problem (CSLP) is a combinatorial complexity that regards numerous objectives and considerable growth of scale as increasing of constraints and facilities. The rearrangement on site may thus need to be had dynamic plannings at several interval schedules as construction evolves to accommodate site needs. To resolve the complexity of this problem, many studies based on the Meta-heuristic approach have been done, there are however always drawbacks and should be improved to be more optimal. This research proposes a new Hybrid Meta-heuristic model which is a combination of Ant Colony Optimization algorithm (ACO), Bacterial foraging algorithm (BFA), and Pair-Wise Exchange Heuristic algorithm (PWEH). The proposed algorithm is named Dynamic Hybrid Ant Colony Algorithm (DHACA) model that can enhance local and global searches simultaneously. In addition, parameter values are optimized to create a better solution. This research also demonstrates the effectiveness of DHACA compared with the previous studies such as Multi-objectives Genetic Algorithm (MOGA), Simulated Annealing Algorithm based Multi-objectives Genetic Algorithm (SA-based MOGA) on the CSLP. DHACA supports the construction site dynamic planning with constraints on facilities to improve work efficiency.

ESG-banking in Russia and the European Union: concept and problems of legal regulation
Authors: Ermakova Elena P.
Published: August 2021

The article presents the author's view of the current situation with the regulation of ESG-banking in Russia and the European Union. According to the author, the ESG-banking business model is the conduct of banking business in accordance with the sustainable development standards enshrined in the UN. At the national level, ESG-banking must comply with taxonomy parameters. Taxonomy provides for the identification and classification of phenomena and processes to assess the results of ESG-banking. The author came to the following conclusions: 1) there is currently no established international practice in regulating ESG issues: the problem is not a lack of existing standards or frameworks, but the absence of a universal standard; 2) in 2020, documents regulating ESG-banking were published in Russia and the European Union: in the Russian Federation - Recommendations for the implementation of the principles of responsible investment dated 15.07.2020 and Regulation on securities issue standards No. 706-P of the Bank of Russia; as well as Methodological recommendations on "green financing" from 13.07.2020 "VEB.RF"; in the European Union - the EU Taxonomy Regulation dated 18.06.2020, as well as the ECB's Climate and Environmental Risk Guidelines dated 27.11.2020; 3) the adoption of the Federal Law “On Environmental Audit and Environmental Auditing”, developed by the Ministry of Natural Resources and Environment of the Russian Federation, would contribute to the improvement of the implementation of “green” projects in Russia.

ABSTRACT: The aim of this research is to develop warm-up games for junior high school students. The method used in this research is Reaserch and Development (RnD), with the development stage of problem analysis, heating design, heating testing, design revision, retrying, and final product. The instrument in this study used a pulse measurement test and a questionnaire. The data analysis used the eligibility formula for judges assessment, ANOVA analysis calculation, T Test and DN max calculation, namely 220 - age for student and student data. Subjects in the study, students as a small-scale trial amounted to 10 out of 9 boys and 1 girl with an average age of 20 years, the two junior high school students as a large-scale trial totaling 31 of 14 boys and 17 girls. From the three judges, the three games are 98% eligibility, which means that the assessment of the heating design is “Very Worthy” to try out. The results of the development of Game game modifications have three levels, namely the easy level of fun games, moderate levels of small games and difficult levels of big games and each level has a different intensity. The results of the first trial study students scored 60% to 75% in increasing their pulse rate to enter the Training Zone. The second trial of students scored a 60% to 75% increase in pulse rate to enter the Training Zone. That way, warming up with games can be used as an alternative to warming up before doing sports activities.
Prospects for accelerated fertility decline in Africa
Authors: Cleland John
Published: August 2021

The future size of world population depends critically on what happens in sub-Saharan Africa, the one remaining region with high fertility and rapid population growth. The United Nations envisages a continuing slow pace of fertility change, from five births per woman today to three by mid-century, in which case the population of the region will increase by over one billion. However, an accelerated decline is feasible, particularly in east Africa. The main grounds for optimism include rising international concern and funding for family planning (after fifteen years of neglect), and favourable shifts in the attitudes of political leaders in Africa. The examples of Ethiopia and Rwanda show political will and efficient programmes can stimulate rapid reproductive change.
Bioproportionality: a necessary norm for conservation?
Authors: Mathews Freya
Published: August 2021

In the early stages of the environment movement, one of the principal objects of conservation was wilderness. In the 1980s, the category of wilderness gave way to that of biodiversity: conservation was reconceived as biodiversity conservation. With this change of categories, the focus of conservation shifted from the saving of vast and abundant terrains of life to the saving of types of living thing, particularly species. A little-noted consequence of this reframing was a reduction in scale: minimum viable populations of species, which set targets under the new biodiversity-based conception of conservation, were often orders of magnitude lower than the populations that might have occurred in wilderness areas. Exclusive focus on the value of diversity thus tended to lead conservationists to lose sight of the value of abundance. To correct this disastrous miscarriage of environmental intentions, a new complementary category is here proposed: bioproportionality. It is not enough to conserve minimum viable populations of all species. The aim should be to optimize such populations. Optimized targets will be estimated by reference to the principle of bioproportionality: the population of each species should be as abundant as is consistent with an ecologically proportionate abundance of adjoining populations of other species. Applied to the human population, this principle will require a dramatic reduction.
Denmark: experience of market turnover of agricultural land
Authors: Yurchenko Ihor
Published: August 2021

The purpose of the article is to reveal the experience of the functioning of the market circulation of agricultural land in Denmark, in order to further implement in Ukrainian practice, the positive and avoid negative aspects of this experience. Research methods. The study used an empirical method (comprehensive assessment of the modern model of market turnover of agricultural land in Denmark); generalization and systematization (construction of the concept and logical-structural model of economic turnover of lands); abstract-logical method (theoretical generalizations and formulation of conclusions). Research results. It was found that the tightly regulated market turnover of agricultural land in Denmark was changed to a more liberal one, with permission to buy land for foreigners, but this not only did not attract investment as expected, but on the contrary, led to even more negative and crisis phenomena in country. The main tools, mechanisms and conditions of land turnover in agriculture of this country are determined. Scientific novelty. The main purpose of regulating the market turnover of land in Danish agriculture has been established. The legal framework of Denmark for regulating the market circulation of agricultural land has been studied. The structural and logical scheme of market circulation of agricultural lands is formed. The provisions on the Ukrainian model of regulating the market turnover of agricultural lands were further developed, taking into account the experience of the studied country. Practical significance. The results of the study of the experience of the Kingdom of Denmark on the market turnover of land, in terms of granting non-residents access to the right to purchase agricultural land, is a clear practical answer and a caveat that should undoubtedly be taken into account in Ukraine. The application of the Danish experience should help to build an effective model of market turnover of agricultural land in our country. Tabl.: 1. Figs.: 1. Refs.: 18.

Published: August 2021

Background: The aim of the present study was to examine the diagnostic capacity of this new parameter towards early signs of renal disease in patients suffering from prolonged RA requiring potential nephrotoxic therapy.

Methods: The present study was a cross sectional observational type of study conducted in the department of medicine Mathura Das Mathur Hospital,    Dr. S.N. Medical College, Jodhpur. A total of 50 subjects that fulfilled the inclusion and exclusion criteria were enrolled in the study after informed and written consent. As per methodology complete blood count, ESR, liver function test, kidney function test, cystatin-c, urine complete, 24 hours urine creatinine, USG abdomen for kidney size were performed.

Results: cystatin–C level below 0.95 mg/dl was considered normal. 19 patients have normal and 31 patients have abnormal more than 0.95 mg/dl.

Conclusion: In conclusion, as compared to serum creatinine, the determination of serum cystatin C is comparably simple, but by far more sensitive for the diagnosis of incipient renal damage in RA, and therefore valuable for clinical screening particularly in cases with prolonged antirheumatic treatment.

Origen, significado y práctica de la “gobernanza global” en la época de la globalización: una mirada histórica desde la perspectiva de los cambios climáticos
Authors: Petrone Francesco
Published: August 2021

En este paper nos proponemos de contextualizar de manera crítica el origen y el sentido de la “gobernanza global” en la época de la globalización, y luego analizamos su aplicación en la gestión de los cambios climáticos. Antes de todo describimos el concepto de globalización, interpretado bajo su enfoque pluridisciplinar, subrajando su complejidad y sobre todo el efecto que ha habido sobre el policy making y la así llamada “crisis del Estado”. Analizamos después el significato de la gobernanza global y sus implicaciones en una época en que ya no existe una centralidad en la gestión de problemas globales, si no que hay siempre más intereses diversos y plurales en juego. Finalmente aplicamos este concepto, bajo una perspectiva histórica, al ámbito de los cambios climáticos. Es éste un campo amplio, por eso nos limitamos a hablar, tomandolos como exemplos, de las cumbres originarias (Estocolmo y Río de Janeiro) y de la COP21 (Paris), para evaluar, finalmente, si y como es posible  superar los límites de la gobernanza delante a semejantes desafíos.

Considerando la importancia de la evaluación dentro del proceso de enseñanza aprendizaje, las posibilidades formativas que otorga la tecnología a través de las plataformas educativas virtuales y la baja utilización de la plataforma virtual que dispone la Universidad Central de Chile, se implementó un proyecto de innovación educativa destinado a identificar fortalezas y debilidades en la aplicación de evaluaciones en línea de una asignatura disciplinar correspondiente al primer semestre de la carrera de Trabajo Social, considerando un total de 25 estudiantes, ajustando dicha evaluación a los objetivos de aprendizaje establecidos para tal asignatura, a través de una metodología mixta que recogió datos cuantitativos mediante una encuesta, mientras que, desde lo cualitativo, se realizó un grupo focal. Los resultados arrojaron como fortalezas la posibilidad de contar con retroalimentación inmediata acerca del avance de los aprendizajes obtenidos, lo que incide favorablemente en la motivación de los y las estudiantes, así como la fácil aplicabilidad de ciertos instrumentos evaluativos, y la posibilidad de entrenar el uso de las TICs en el escenario docente actual.Entre las debilidades, se identificó el mayor tiempo que implica el diseño instruccional y validación de los instrumentos evaluativos para el equipo docente, la escasa preparación de los docentes respecto al uso de todas las aplicaciones del aula virtual.Los hallazgos de la implementación del proyecto de innovación educativa se constituyen en un aporte al trabajo del comité curricular de la carrera, ya que deja en evidencia las posibilidades de réplica en los distintos niveles  por su incidencia positiva en la motivación del estudiante y al mismo tiempo dan cuenta de la necesidad de generar instancias formativas que tributen al desarrollo de competencias digitales tanto en profesores y especialmente en estudiantes con la finalidad de desarrollar una actitud positiva, crítica y realista respecto de las fortalezas y debilidades del uso de la tecnología en el proceso de enseñanza aprendizaje en el actual contexto de aprendizaje en la sociedad del conocimiento y la era digital en dónde el acceso a los diversos beneficios de la  política social a los cuales se accedía de manera presencial se ha trasladado a plataformas virtuales.Así mismo, este artículo aporta a la reflexión de la evaluación en línea implementada en la educación superior, desde la perspectiva de profesores y estudiantes, que puede facilitar su ajuste y desarrollo en otros contextos similares.

The mixtures containing polypropylene are used in the industrial sector as material for bags, chairs, household items, and can even be used in cell phone batteries. The interest in creating this material is due to its low density compared to more common materials such as iron and ceramic, in addition to its good corrosion resistance and reasonable mechanical properties in environments without high temperature and pressure. In order to diversify the mechanical and viscous properties, different types of polymers were used, such as lactic polyacid, which has beneficial properties for recycling such as degradation. It is a challenge to control the right proportion and use additives and plasticizers to control the desired properties. The methods used to measure the properties of polypropylene and polylactic acid mixtures with different types of additives, compatibilizers and plasticizers were DMA, TGA, tensile, DSC and rheology tests following ASTM standards. The results were promising, observing different mechanical and viscosity properties for the PP/PLA/PP-g-MA/D mixture in different proportions. Thus concluding that the different products have varied application in the industry.

Sexuality began to be seen as a positive scope of human action, in this context, it began to value sexual education, raising discussions about its importance. The aim of this article was to analyze knowledge about forms of contagion and prevention of STIs. This study was conducted in 03 state schools of elementary and secondary level. The sample consisted of 287 students regularly enrolled in these schools covering the 8th grade/ 7th grade of elementary school until the 3rd year of high school. Data on gender, age, marital status, education and others were collected in this study. Most participants have already had contact with the term STI; however, it still has beliefs about its forms of transmission. There is a need to approach sexuality with a more natural and positive aspect of human life, providing the free discussion of norms and patterns of behavior and the debate of attitudes.
Recent Approaches, Catalysts and Formulations for Enhanced Recovery of Heavy Crude Oils
Authors: Gaya Umar
Published: August 2021

Crude oil deposits as light/heavy form all over the world. With the continued depletion of the conventional crude and reserves trending heavier, the interest to maximise heavy oil recovery continues to emerge in importance. Ordinarily, the traditional oil recovery stages leave behind a large amount of heavy oil trapped in porous reservoir structure, making the imperative of additional or enhanced oil recovery (EOR) technologies. Besides, the integration of downhole in-situ upgrading along with oil recovery techniques not only improves the efficiency of production but also the quality of the produced oil, avoiding several surface handling costs and processing challenges. In this review, we present an outline of chemical agents underpinning these enabling technologies with a focus on the current approaches, new formulations and future directions.

Due to increase in demand for energy as a result of human population explosion, industrialization and environmental hazards posed by fossil fuels, there is a need to source for alternative energy sources that are cheaper and environmental friendly. Three different lignocellulosic biomasses were studied for their suitability for bioethanol production. Fungi and yeasts were isolated using serial dilution and spread plate methods. Identification of both fungi and yeasts was done using their cultural and microscopy characteristics. Saccharification of the pre-treated biomass was done with both crude cellulase and mycelia inoculant. Bioethanol was produced using batch culture fermentation. Ethanol produced was detected using spectrometric method and quantified using High Performance Liquid Chromatography (HPLC). The effects of substrate concentration, pH and temperature on ethanol yield were optimized. Fifty fungal isolates were obtained from soil collected. Six yeasts, all Kluyveromyces species fermented three sugars to ethanol with isolate Kluyveromyces sp.Y2 having the shortest time. It was selected for fermentation. Aspergillus niger S48 had highest cellulase activity measured in a zone of hydrolysis of 26.0 mm. It had the highest glucanase activity, endoglucanase (0.462 U/mL) and exoglucanase (0.431 U/mL). The outcome of this study indicated that crude cellulase produced by Aspergillus niger S48 hydrolyzed the pre-treated rice chaff with 1.07 mg/mL of fermentable sugars higher than 0.87 mg/mL when the mycelia of the fungus was inoculated to pretreated rice chaff for hydrolysis. Ethanol was optimally produced at 12 % substrate concentration using rice chaff, at a temperature of 35 °C and pH 5.0.
SCIENTIFIC EPONYM IN EDUCATIONAL UNIVERSE

Strictly speaking, knowledge for every object in educational Universe is limited by ignorance or, in other words, these two components co-exist. However, pedagogy primarily deals with knowledge, its acquisition and retention. It ignores the ignorance, leaving it as a subject for a more generic science of psychology. Similarly, atomic nuclei in real Universe are a subject for a more generic science of physics, being only slightly studied in chemistry. To research on knowledge is by far easier than on ignorance, same as chemical research involving mere electron shells is easier than physical research targeting atomic nuclei.

As part of its role in the World Health Organization’s (WHO) Global Influenza Surveillance and Response System (GISRS), the WHO Collaborating Centre for Reference and Research on Influenza in Melbourne received a record total of 9,266 human influenza positive samples during 2019. Viruses were analysed for their antigenic, genetic and antiviral susceptibility properties. Selected viruses were propagated in qualified cells or embryonated hen’s eggs for potential use in seasonal influenza virus vaccines. In 2019, influenza A(H3N2) viruses predominated over influenza A(H1N1)pdm09 and B viruses, accounting for a total of 51% of all viruses analysed. The majority of A(H1N1)pdm09, A(H3N2) and influenza B viruses analysed at the Centre were found to be antigenically similar to the respective WHO recommended vaccine strains for the Southern Hemisphere in 2019. However, phylogenetic analysis indicated that a significant proportion of circulating A(H3N2) viruses had undergone genetic drift relative to the WHO recommended vaccine strain for 2019. Of 5,301 samples tested for susceptibility to the neuraminidase inhibitors oseltamivir and zanamivir, four A(H1N1)pdm09 viruses showed highly reduced inhibition with oseltamivir, one A(H1N1)pdm09 virus showed highly reduced inhibition with zanamivir and three B/Victoria viruses showed highly reduced inhibition with zanamivir.
