Authors: Vijayasingh Neginah , Athiappan Murugan
Published: May 2024

Severe acute respiratory syndrome corona virus 2 (SARS-CoV2) is a highly pathogenic RNA virus. Inhibition of SARS CoV 2 by molecular docking using the microbial metabolites of tannin rich fruit kernels of Punica granatum, Mangifera indica, Phyllanthus emblica and Syzygium cumini produced using a probiotic bacterium Bacillus coagulans. SARS CoV2 uses its spike proteins to inhibit the viral entry and uses main protease and chymotrypsin like protease to inhibit protein transcription, translation, maturation and replication. The accelerated immune response which is cytokine storm, can be managed by inhibiting the activation of nuclear factor kappa B (NF-κB). Excess of tissue deposition on the lung causing fibrosis can be treated by inhibiting the fibrotic pathological pathway targeting the G coupled receptor protein mediator 40 and 84 (GPR40 and GPR84) to prevent fibroblast. “Autodocking of metabolites extracted from kernel Punica granatum and Mangifera indica results in identifying 1H-Purin-6-amine, [(2-fluorophenyl) methyl] and tricarbonyl (N-cyclopent-2-en-1-yl-N-phe nyl-1-4-.eta.-cyclohexa-1,3-dienecarboxamide)iron of which 1H-Purin-6-amine, [(2-fluorophenyl)methyl] or 6-(3-fluorobenzylamino) purine appears to be very effective against SARS CoV-2 inflammation and fibrosis as evidenced by molecular docking. The role of probiotic bacteria in the synthesis of bioactive metabolites is established as very significant.
Quantum Control of Nonlinear Dynamics in Confined Systems

Published: May 2024

Investigating nonlinear fluid dynamics remains a challenge across physics from nanofluidics and biophysics to astrophysics. Here we introduce a quantum/classical theoretical approach that takes into account both quantum correlations and classical behaviour within a 2D fluid that is confined in a 3 μm side square. We employ a modified Gross-Pitaevskii equation, encompassing many-body interactions and confinement. This system reveals complex fluid dynamics characterised by dissipative solitons; a significant outcome is an asymptotic function that describes the soliton behaviour. The solitons exhibit intriguing geometrical and temporal transformations, guided by subtle phase gradients. We trace the soliton evolution from 1 to 83 ns, revealing the emergence of geometric oscillations in amplitude and phase angles. Under these phase gradients, solitons transition to states with reduced amplitude and expanded spatial profiles. These results show that geometric solitons can emerge from a quantum noisy environment, and lead us to propose an interesting possibility: it is feasible to control and manipulate nonlinear dynamics in systems with finite-range interactions and confinement using quantum control. By bridging quantum and classical dynamics, this study links various scientific disciplines, including non-equilibrium phases of condensed matter, unconventional/quantum computing and advanced control of nanofluidics. From a more fundamental perspective, this possibility of quantum control of classical behaviour advances our understanding of physics within multidimensional Hilbert spaces.

Published: May 2024

Efficient drug discovery relies on accessing diverse small molecules expediently and reliably. Improvements to reliability through machine learning predictions are hampered by poor availability of high-quality reaction data. Here, we introduce an on-demand synthesis platform based on a three-component reaction that delivers drug-like molecules overnight. Miniaturization and automation enable the execution and analysis of 50,000 reactions on a 3 microliter scale with distinct substrates, producing the largest public reaction outcome dataset. With machine learning, we accurately predict the result of unknown reactions and analyze the impact of data set size on model training. This study advances the on-demand synthesis of drug-like molecules through concatenating chemoselective reactions and provides a sufficiently large data set to critically evaluate emerging machine learning approaches to predicting chemical reactivity.

Published: May 2024

Accelerated production of recyclable and biodegradable biopolymers is crucial in combating the socio-economic and environmental issues of fossil-based plastics. While renewable diacids have been in the spotlight for the generation of bio-based polyesters with tailored properties by varying the alkyl chain length, capitalizing on diols from biomass for this purpose is underexplored and has mainly focused on linear and branched shorter chain alcohols. Here we explored the potential of two (ꟷ)-α-pinene-derived diols (PDOs) as building blocks to generate polyesters that mimic the properties of aromatic fossil-based polymers when combined with renewable diesters. The semi-crystalline or amorphous nature of the resulting polymers is tunable with the appropriate choice of diester. We demonstrate a concise synthesis of two novel unsymmetrical chiral PDOs on 20-40 g scale, together with eight structurally differing polyesters with excellent thermal stability; as reflected by high melting (270 oC, 277 oC), and glass transition temperatures (90 oC, 121 oC) for two of the polymers. The steric hindrance of the intact bicyclic α-pinene ring structure protruding from the backbone of the polymers can also aid in the degradation process, manifested by facile chemical recycling of these polyesters under mild conditions to recover both monomers. Finally, our results show how the generated rigid polymers are prone to enzymatic degradation by PETase and cutinase without any chemical pre-treatment. Our results illuminate the potential of expanding the currently available chemical space in bio-based monomers to bicyclic diols to generate biomaterials with tailormade properties.

Ribonucleic acid (RNA) molecules can adopt a variety of secondary and tertiary structures in solution, with stem-loops being one of the more common motifs. Here we present a systematic analysis of fifteen RNA stem-loop sequences simulated with molecular dynamics simulations in an implicit solvent environment. Analysis of RNA cluster ensembles showed that the stem-loop structures can generally adopt A-form RNA in the stem region. Loop structures are more sensitive and experimental structures could only be reproduced with modification of CH---O interactions in the force field, combined with an implicit solvent nonpolar correction to better model base stacking interactions. Accurately modeling RNA with current atomistic physics-based models remains challenging but the RNA systems studied herein may provide a useful benchmark set for testing other RNA modeling methods in the future.

This work provides a procedure and database for obtaining the vibrational frequency scale factors that align quantum chemically computed harmonic frequencies with experimental vibrational spectroscopic data. The database comprises 441 molecules of various sizes, from diatomics to the buckminsterfullerene C60. We provide scale factors for 27 dispersion-corrected methods, 24 of which are DF-Dn/B with DF=BLYP, PBE, B3LYP,~PBE0, Dn=D3(BJ), D4, and B=6-31G, def2-SVP, def2-TZVP, and three of them are the 3c-family composite methods (HF-3c, PBEh-3c, and r2SCAN-3c). The two scale factors are derived for each method: the absolute scaling, minimizing the absolute deviation of the scaled harmonic frequency from the experimental value, and the relative scaling, which minimizes an analogous relative deviation. The absolute type of scaling is recommended for frequencies above 2000 cm-1, while the relative scaling is optimal for frequencies below 2000 cm-1.

Published: May 2024

The reaction of unsaturated compounds with ozone (O3) is recognized to lead to the formation of Criegee intermediates (CIs), which play a key role in controlling the atmospheric budget of hydroxyl radicals and secondary organic aerosols. The reaction network of two CIs with different functionality, i.e. acetaldehyde oxide (CH3CHOO) and glyoxal oxide (CHOCHOO) formed in the ozone-assisted oxidation reaction of crotanaldehyde (CA), is investigated over a temperature range between 390 K and 840 K in an atmospheric pressure jet-stirred reactor (JSR) at a residence time of 1.3 s, stoichiometry of 0.5, and 89% Ar dilution. Molecular-beam mass spectrometry in conjunction with single photon tunable synchrotron vacuum-ultraviolet (VUV) radiation is used to identify elusive intermediates by means of experimental photoionization energy scans and ab initio threshold energy calculations for isomer identification. Addition of ozone (1000 ppm) is observed to trigger the oxidation of CA already at 390 K, which is below the temperature where the oxidation reaction of CA was observed in the absence of ozone. The observed CA + O3 product, C4H6O4, is found to be linked to a ketohydroperoxide (2-hydroperoxy-3-oxobutanal) resulting from the isomerization of the primary ozonide. Products corresponding to the CIs uni- and bi-molecular reactions were observed and identified. A network of CI reactions is identified in the temperature region below 600 K, characterized by CIs bimolecular reactions with species like aldehydes, i.e., formaldehyde, acetaldehyde, and crotonaldehyde and alkenes, i.e., ethene and propene. The region below 600 K is also characterized by the formation of important amounts of typical low-temperature oxidation products, such as hydrogen peroxide (H2O2), methyl hydroperoxide (CH3OOH), and ethyl hydroperoxide (C2H5OOH). Detection of additional oxygenated species such as alcohols, ketene, and aldehydes are indicative of multiple active oxidation routes. This study provides important information about the initial step involved in the CIs assisted oligomerization reactions in complex reactive environments where CIs with different functionalities are reacting simultaneously. It provides new mechanistic insights into ozone-assisted oxidation reactions of unsaturated aldehydes, which is critical for the development of improved atmospheric and combustion kinetics models.

Published: May 2024

Grounded theory (GT) has appeared as a popular research approach in many branches of social science that acts for the well-being of the society. It is an inductive methodology, and focuses on the discovery of theory from data. Overtimes original grounded theory of Barney Galland Glaser (1930-2022) and Anselm Leonard Strauss (1916-1996) has evolved, and two grounded theory variants: Glaserian grounded theory and Straussian grounded theory have been emerged as qualitative approaches. When a novice qualitative researcher starts data collection on grounded theory; s/he cannot identify the differences between the two approaches. In this paper some of the key differences and similarities of the two methods are illustrated. So that, a confused researcher can easily selects the desired grounded theory for his/her research version. In this study an attempt has been taken to continue the grounded theory research smoothly when the novice researchers face uncertainty during the research procedure.
The Onset and Impact of Early Sport Specialization Among Hockey Players from Winnipeg
Authors: Poplawski Brent , Field Russell
Published: May 2024

Early career sport specialization has become increasingly popular among today’s youth athletes. Despite its increasing prominence, this athletic trend has not been historicized in the Canadian context. This paper determines when and why youth athletes began to pursue a certain sport, forgoing other athletic opportunities, as a means to achieve elite-level success. It focuses specifically on hockey players from Winnipeg, Manitoba, who played in the National Hockey League. This qualitative research study uses semi-structured interviews and secondary material to explore the factors that resulted in young male hockey players in Winnipeg being encouraged to exclusively participate in hockey year-round. This study historicizes the shift in youth sport in the post-Second World War period in Canada to better understand the reasons for early sport specialization and the forces that shape contemporary youth sport.
Who Watches and Follows Girls’ and Women’s Sport?
Authors: Allison Rachel , Knoester Chris
Published: May 2024

Despite high and rising consumption of women’s sport in the United States (U.S.), limited research has addressed the social factors that lead individuals to become consumers of girls’ and women’s sport. This study uses 2018-19 National Sports and Society Survey (NSASS) data to examine the frequencies and predictors of U.S. adults’ consumption of girls’ and women’s sport. We integrate social structure and life course theories to consider social structural locations, parental and own sports involvement during childhood, adult gender ideologies, and adult sport commitments as predictors of adults’ consumption of girls’ and women’s sport. The results indicate moderate consumption of female sport, with just over half of adults appearing to spend some time watching/following female sport in the last year. Also, we estimate that U.S. adults average watching/following female sport for about one hour per week, but they report that their watching/following of female sport is typically only a small fraction of their overall sport consumption. Regression findings show consistent evidence of sexuality, number of female family members, parents’ sports fandom or athleticism, childhood sports involvement, adult gender ideologies, and adult sport commitments shaping the consumption of female sport. In addition, there is some initial evidence that gender seems to encourage men to watch/follow more female sports, but women appear more prone to watch female sport as opposed to male sport. However, gender and sexuality interact with one another in predicting female sport consumption, such that gay/lesbian identities particularly heighten consumption of female sport among women. Consequently, there is evidence that lesbians are disproportionately among the most avid consumers of girls’ and women’s sport.
Effects of Coaching Behaviors and Differences in Sport Injury Anxiety Among Cheerleaders
Authors: Braun-Trocchio Robyn
Published: May 2024

The athleticism required in cheerleading has increased dramatically, yet the amount of training cheerleading coaches receive varies considerably. With the skill complexity increasing, one can speculate that sport injury anxiety would be present. Sport injury anxiety is a sport-specific anxiety that focuses on athletes’ apprehensions about sustaining an injury while participating in their sport. Specifically, a cheerleader’s perception of their coach’s behavior may influence their sport injury anxiety. The current study examined coaching behavior as a predictor of sport injury anxiety as well as differences in sport injury anxiety between sex, stunt position, and team type in cheerleaders. Participants included all-girl and coed collegiate teams and all-star teams. Participants completed an online survey consisting of the Leadership Scale for Sport and the Sport Injury Anxiety Scale. Results indicated the coach’s level of training and instruction was able to predict anxiety related to experiencing pain. Female cheerleaders had higher levels of anxiety related to being perceived as weak, experiencing pain, and having an impaired self-image compared to males. All-girl collegiate members had higher levels of anxiety related to losing athleticism, being perceived as weak, and experiencing pain. Coaches should be educated to help reduce sport injury anxiety especially in female cheerleaders.

This study focused on the organoleptic characteristics and consumers’ purchasing decision
of milk jellies made with lactose-free cow milk and various plant-based non-dairy milk,
including almond milk, coconut milk, oat milk and soymilk. All milk alternatives were
measured for the CIE color system. The hedonic scale was used to evaluate product liking
on appearance, color, taste, flavor, texture, and overall acceptability–still, the scaling test
assigned for the purchasing intention. The results showed that milk alternatives' lightness,
taste, and flavor preference affected consumers' liking and purchasing decisions for nondairy milk jellies. Preference mapping showed the relevance of the high lightness of milk
alternatives and product acceptability. Coconut milk jelly was the most preferred, as did
lactose-free milk jelly, while soymilk jelly was the least.

В роботі розглянуті особливості отримання та застосування матеріалів класу С/SiC у вигляді вуглець-карбідокремнієвих конструкцій в різних галузях техніки. Робота спрямована на розробку математичної моделі осадження піролітичного карбіду кремнію на пористу поверхню вуглець-вуглецевих композиційних матеріалів із суміші газів на основі метану CH4 та SiCl4. Піролітичний карбід кремнію утворюються в результаті термічної дисоціації кремнійорганічних сполуктетрахлориду кремния (SiCl4) або метилтрихлорсилану (CH3SiH3). При ущільненні піролітичним карбідом кремнію армованих композиційних матеріалів кремнійорганічні сполуки в зону реакції потрапляють спільно з воднем або метаном, які одночасно є газом-відновником і газом носієм. Процес осадження чистого карбіду кремнію конкурує з осадженням вуглецю та суміші карбіду кремнію з вуглецем. Тому одним з завдань роботи є забезпечення таких умов протікання гомогенно-гетерогенних процесів, які б реалізувати осадження чистого SiC. При піролізі метилтрихлорсилану в інтервалі температур 800-1000°С утворюється SiC високої щільності та фіолетового відтінку. З підвищенням температури піролізу метилтрихлорсилану колір покриття переходить у сірий. Розмір кристалів становить близько 22 нм. Вихід SiC знаходиться в межах 25 – 35%. Максимальний вихід кремнію карбіду спостерігається в інтервалі температур 1250 – 1500 °C. Підвищення температури до 1600 °C не істотно впливає на вихід SiC. В процесі дослідження встановлено, що найбільш актуальним є хіміко-термічне осадження з газової суміші метану та тетрахлориду кремнію під час якого досягається стехіометричне осадження SiC без ушкодження вуглецевих волокон у карбонизированних вуглепластиках з карбідизованою матрицею. В роботі визначені теоретичні константи рівноваги уявленнях термохімічних реакцій. Визначено формули для оцінки продуктивності термохімічного реактора в умовах квазірівноважного режиму осадження карбіду кремнію.

Background: The mental health of students plays a crucial role in their learning and performance. The COVID-19 pandemic, the political turmoil and a coup in Sudan has exacerbated stress and anxiety among university students in Sudan due to uncertainty about their academic activities. Aim: To assess post-traumatic stress disorder (PTSD) occurrence and coping strategies adopted by university students in Sudan. Methods: This cross-sectional survey was conducted from March to June 2022. It used the Coping Orientation to Problems Experienced (Brief-COPE) and Impact of Event Scale-Revised (IES-R) questionnaires to assess the occurrence of PTSD and coping strategies among 596 university students in Sudan. Descriptive statistics were used to determine the frequency and percentage, Student's t test was used to compare the means of 2 groups and one-way analysis of variance to compare the means of ≥ 3 groups. Results: There was a high prevalence of PTSD among the students, with a score of 31.2 (SD 16.4). The total score of PTSD was higher among female students. Around 36% of the students had a PTSD score > 37, which is considered high enough to suppress immune function. The most widely adopted coping strategies were religion and acceptance of the situation, while substance use was the least. Students who had COVID-19 infection during the pandemic differed significantly from uninfected students in the application of coping strategies. In contrast, students whose family members or friends had COVID-19 were not significantly different from students with uninfected family members or friends in the application of the coping strategies, such as self-blame, denial, substance use, and behavioural disengagement. Conclusion: We recommend the initiation and implementation of psychological counselling programmes for university students in Sudan onsite or remotely. Further research should be carried out to assess the long-term effects of the pandemic and the political conflicts so as to design and implement appropriate and efficient interventions

Background: Early and accurate diagnosis is crucial for preventing the spread of SARS-CoV-2 infection. The rapid antigen test was developed for testing infection, and it was necessary to assess its performance before widespread use in Tunisia. Aim: To evaluate the effectiveness of a rapid antigen test for the detection of SARS-CoV-2 in nasopharyngeal swabs in Tunisia. Methods: Nasopharyngeal samples were taken from COVID-19 suspected cases between October and December 2020 and tested using the Standard Q COVID-19 Ag test (SD-Biosensor, Republic of Korea) and real-time reverse transcription polymerase chain reaction (RT-PCR). Results: Overall, 4539 patients were tested. Of the total study population (N = 4539), 82.5% of positive samples remained positive with the rapid antigen test, while 20.2% (470/2321) of samples that were negative with rapid antigen test were confirmed positive with RT-PCR, giving a negative predictive value of 79.8% for the rapid antigen test. The sensitivity and negative predictive value of the rapid antigen test were 70.2% and 65.8%, respectively. These results improved to 96.4% and 92.8%, respectively, when considering the cycle threshold value by RT-PCR below 25. Conclusion: Although the rapid antigen test was less sensitive than RT-PCR, its ability to rapidly detect individuals with high viral loads makes it suitable for use during an epidemic.

Food literacy is achieving attention worldwide and gaining traction in Arab countries. Strengthening food and nutrition literacy among Arab teenagers are important promising and empowering tools, which can protect them from malnutrition. This study aims to evaluate the nutrition literacy status of adolescents along with that of their parents in 10 Arab countries. This cross-sectional study involving a convenient sample of 5401 adolescent-parent dyads was launched between 29 April and 6 June 2022 in 10 Arab nations. The Adolescent Nutrition Literacy Scale (ANLS) and the Short Food Literacy Questionnaire (SFLQ) were used to meet the study aims. More than one-quarter (28%) of adolescents had poor nutrition literacy, with 60% of their parents being food illiterate. The top three countries with nutritionally less literate adolescents were Qatar (44%), Lebanon (37.4%), and Saudi Arabia (34.9%). Adolescents’ age, gender, education level, primary caregivers, employment status, and the inclusion of nutrition education in the schools’ curriculum predicted the nutrition literacy levels of Arab adolescents. Besides, parental weight status, health status, parent’s food literacy level, and the number of children per household were significant determinants too. Nutrition literacy inadequacy among Arab adolescents is a prioritized challenge to be tackled to achieve the sustainable developmental goals (SDGs) mainly SDG2 and SDG4.

Published: May 2024

Purpose: The aim of this article is to identify the most common fields of study undertaken by researchers in scientific papers covering simultaneously the gig economy and sustainable development. Design/methodology/approach: The research study used a structured literature review method. The structured bibliometric query Q1 allowed for the exploration of the Scopus database. As a result, 48 scientific studies from the period 2017-2023 were selected for analysis, which simultaneously addressed the issues of the gig economy and sustainable development. Findings: The analyses carried out showed that the issue of sustainable development is addressed in the context of the gig economy. This is a relatively new research area, as shown, for example, by the generated database of studies used for the bibliometric analyses conducted. The issues of sharing economy and decent work are important areas addressed in the context of the gig economy. It was noticed that there was a lack of author keywords covering 'green' issues. Research limitations/implications: Research results based on other databases (e.g. Web of Science) may lead to different results. It should be noted that the different bibliometric databases do not overlap, which is related to the indexing of scientific journals or publications in the databases. Nonetheless, a universal query was used in the study, which can be used in the various bibliometric databases once it has been adapted to their respective query form. In addition, the various databases are constantly being supplemented with new scientific papers, which also depends on the publishing process. Hence, the content of the Q1 query can in future be used for comparison purposes with the results obtained, or to compare different bibliometric databases with each other. Originality/value: In the discussion that followed, attention was drawn to the issues of green jobs and green self-employment. In the authors' opinion, such research directions, although not yet visible in the authors' keywords, will be developed soon in the context of studies covering the issues of the gig economy and sustainable development considering the green transformation of the economy taking place. This article is addressed to all those who are interested in the issues of the gig economy and sustainable development. Keywords: gig economy, green jobs, green labor market, green self-employment, sustainable development. Category of the paper: Literature review.
