Screening Chemical Composition and Bioactive Properties of Mentha x piperita L. Essential Oil and Extract

In recent years, medicinal and aromatic herbs, which contain variety of antimicrobial compounds and have no risk to human health in terms of antibiotic resistance, are increasingly used as alternatives to antibiotics. In the study, chemical composition, total phenolic content, antioxidant and antimicrobial activity of essential oil and extract of Mentha x piperita L. growing wild in Eskisehir were investigated. Carvone (55.8%), limonene (12.8%), 1.8-cineole (8.7%) and trans-dihydrocarvone (6.4%) were determined as the main constituents of the essential oil, while the major components of the extract were carvone (56.4%), 1.8-cineole (14.1%) and trans-dihydrocarvone (8.4%). The total phenolic contents of essential oil (2204.33 µg GAE/g) were significantly higher than of extract (744 µg GAE/g). The essential oil and the extract were inhibited 84.08% and 42.59% by the DPPH radical, 91.87% and 48.40% by the ABTS radical, respectively. The highest inhibition zone was observed against S. aureus (23 mm). However, minimum inhibition concentration (MIC) values of the essential oil were ranged between 2.5% and 10% (v/v), while MIC values of the extract were determined as 10% and >10% (v/v). The present study demonstrated that M. piperita could be used in pharmaceutical and food applications as a natural antioxidant and antimicrobial substance.
HARNESSING TECHNOLOGY TO RESPOND TO THE GLOBAL DEMAND FOR LEARNING DURING THE COVID-19 PANDEMIC

The COVID-19 pandemic generated an unprecedented global demand for learning about the disease and how to manage it. This paper draws on theWorld Health Organization (WHO)'s experience of COVID-19 knowledge-transfer to a worldwide audience of millions of learners registered on OpenWHO, WHO's massive open online course platform. It aims to illustrate the technological solutions that WHO, in collaboration with the Hasso Plattner Institute (HPI), OpenWHO's platform provider, employed in response to the unique challenges this surge in demand for learning engendered. Data on OpenWHO use, including geographic patterns and certificate attainment, were extracted from OpenWHO's internal and external reporting systems. Descriptive analysis was employed to identify trends and compare OpenWHO use with COVID-19 caseload in each WHO region. Data on the OpenWHO system load were obtained from the OpenWHO load balancer (HAProxy). The OpenWHO team responded to the need for trustworthy, evidence-based knowledge on COVID-19 via three main avenues: increased scale, targeting the needs of affected and underserved communities, and prioritising multilingualism. Each approach brought novel problems, which WHO and HPI leveraged their collaboration to meet by employing technology. This included increasing server bandwidth, expanding support teams, adding new language capabilities, and deploying functions to streamline workflows and boost learner experience. In doing so, the ability to effectively and efficiently harness technology became a critical step towards empowering learning's life-saving potential during the COVID-19 pandemic. © 14th International Conference on ICT, Society, and Human Beings, ICT 2021, 18th International Conference on Web Based Communities and Social Media, WBC 2021 and 13th International Conference on e-Health, EH 2021 - Held at the 15th Multi-Conference on Computer Science and Information Systems, MCCSIS 2021.

Likelihood of Insurance Coverage on Damages Due to Level of Insecurity in Nigeria: Logistic Modeling Approach

Insurance serves as a protection against the unexpected and it is one of the most effective risk management tools that protect individuals from being bankrupt due to various contingencies. The binary logistic regression model approach was used to model the described dataset; the model so obtained was statistically significant. All the levels of education were statistically significant in predicting the odds of having insurance cover except for primary education level. Also, employment status and age were statistically significant in predicting the likelihood for insurance cover in Nigeria. The results showed that individuals who move from no formal education to obtain Higher education level are 21.66 times more likely to obtain insurance cover and individuals who move from no formal education to obtain Secondary education level are 2.63 times more likely to obtain insurance cover. The odd ratio is not significant for moving from no formal education to Primary education and therefore should not be interpreted. Further, individuals who move from being unemployed to being employed are more likely to obtain insurance cover. Education has the highest impact in predicting the likelihood for one to have insurance cover in Nigeria. This paper recommends overhauling of the educational system in order to revamp this sector.
Morphological, Physical and Biochemical Characteristics of the three Main Varieties of Mango (Mangifera indica L.) Cultivated in the Poro Region (North of Côte d'Ivoire)

Mango processing in Côte d'Ivoire is limited by data failure on characteristics of mango varieties. The purpose of this work is to contribute to the valorization of the main varieties of mango (Amelie, Kent and Keitt) cultivated in Côte d'Ivoire through the evaluation of their morphological, physical and biochemical parameters. Between May and June 2020, ten ripe fruits of each variety were randomly selected from ten batches of mangoes from different producers in the Poro region. After sampling, morphological, physical and biochemical parameters were determined at the biochemistry - microbiological laboratory of Peleforo Gon Coulibaly University in the month of June 2020. This study showed that the mangoes Kent and Amelie were bigger than those of Keitt. However, when ripe, the three mango varieties studied had each a specific gravity close to 1 g/cm3; they could therefore float on water. They were elongated in shape and corresponded to the caliber group B of mangoes exportable to the European market. The high values of pulp proportions (82.70 to 83.62%), pulp/stone ratios (12.71 to 13.33) and waste indices (4.69 to 5.20) gave them interesting aptitudes for industrial processing. With high moisture contents (77.80 to 84.80%), low fiber contents (0.53 to 0.84%) and acidity values (0.20 to 0.50%), interesting ascorbic acid contents (45.02 to 46.25 mg/100g ), TSS contents (15.51 to 18.50 °Brix) conforming to standard for fruit juices and nectars, the mango varieties studied would be suitable for making puree, juice or ice cream. However, with a higher sugars/acidity ratio (73.46), mango variety Kent would be more suitable for drying and making frozen or canned mango pieces; while those of Amelie and Keitt would be suitable for the manufacture of purees, concentrates and drinks. The results of this study could guide processors in the choice of varieties according to the types of derived products. They are interesting and should be deepened by including other varieties (improved and local) cultivated in Côte d'Ivoire.
The effects of psilocybin on cognitive and emotional functions in healthy participants: Results from a phase 1, randomised, placebo-controlled trial involving simultaneous psilocybin administration and preparation

Background: Psilocybin, a psychoactive serotonin receptor partial agonist, has been reported to acutely reduce clinical symptoms of depressive disorders. Psilocybin’s effects on cognitive function have not been widely or systematically studied. Aim: The aim of this study was to explore the safety of simultaneous administration of psilocybin to healthy participants in the largest randomised controlled trial of psilocybin to date. Primary and secondary endpoints assessed the short- and longer-term change in cognitive functioning, as assessed by a Cambridge Neuropsychological Test Automated Battery (CANTAB) Panel, and emotional processing scales. Safety was assessed via endpoints which included cognitive function, assessed by CANTAB global composite score, and treatment-emergent adverse event (TEAE) monitoring. Methods: In this phase 1, randomised, double-blind, placebo-controlled study, healthy participants (n = 89; mean age 36.1 years; 41 females, 48 males) were randomised to receive a single oral dose of 10 or 25 mg psilocybin, or placebo, administered simultaneously to up to six participants, with one-to-one psychological support – each participant having an assigned, dedicated therapist available throughout the session. Results: In total, 511 TEAEs were reported, with a median duration of 1.0 day; 67% of all TEAEs started and resolved on the day of administration. There were no serious TEAEs, and none led to study withdrawal. There were no clinically relevant between-group differences in CANTAB global composite score, CANTAB cognitive domain scores, or emotional processing scale scores. Conclusions: These results indicate that 10 mg and 25 mg doses of psilocybin were generally well tolerated when given to up to six participants simultaneously and did not have any detrimental short- or long-term effects on cognitive functioning or emotional processing.

Reinvestigation of High Lift Airfoil under the Influence of Heavy Rain Effects

Global warming has led to extreme weather such as heavy rain happens more frequently. Aircraft taking-off and landing will unavoidably meet with heavy rain, but aerodynamic influences of high lift airfoil due to heavy rain have least information and needs further investigation. In this work, we first review recent research finding of heavy rain effects on the aerodynamic performance degradation. To further investigate the rain physics, CFD method and preprocessing grid generator are used as our main analytical tools, and the simulation of rain is accomplished via two-phase flow approach’s Discrete Phase Model (DPM) combined with the high lift devices’ surface roughness effects. The current discoveries show that we successfully simulate the aerodynamic efficiency degradation of a typical commercial high lift airfoil during landing phase under the heavy rain situation. Through proper modeling of discrete water droplets, shear flow between airfoil elements, detailed analysis of pressure distribution, viscous drag and pressure drag contribution of slat, main wing, vane, and flap, and roughened cratering effects on airfoil surfaces, it is found that similar to the experiment, the high lift airfoil lift-to-drag ratio degradation rate will increase with the heavy rain rate, and the premature stall phenomenon is discovered as well.
Student Parents and HIPs: Missing Out on High-Impact Practices

Abstract High Impact Practices (HIPs) have become a flashpoint of efforts to create transformative higher education experiences that lead not only to greater success while in college but also result in life-long educational and personal benefits. In this article, we identify a growing category of students who are systematically excluded from engaging in many types of HIPs: student parents. Based on a survey of both student parents and non-parents at a regional comprehensive public university in the upper Midwest, we demonstrate, through both qualitative and quantitative data, the consistent barriers that student parents face in accessing HIPs as well as the self-help strategies and campus resources they employ to mitigate these challenges. We conclude by discussing implications and offering recommendations on both the institutional and individual levels designed to change the current status quo. On a theoretical level, the article brings together concerns and insights of two types of scholarship: higher education literature on HIPs and the research on equity and inclusion in higher education, especially advocacy on behalf of student parents. We find that previous studies of HIPs did not discuss this demographic, and it remains underserved in the new educational efforts to provide all students with richer and more impactful learning experiences.
E-VOTING AND NON-RESIDENT CITIZENS' VOTER TURNOUT: A QUASI-EXPERIMENT IN ECUADOR

Over the last decades, e-voting has been used in a large number of countries and its impact on voter turnout has been closely scrutinized. Regardless, scholarly attention has largely focused on turnout in the domestic arena, and the link between e-voting and external voting have been scarcely explored. Based on a quasi-experimental design of the 2021 Ecuadorian elections, we investigate the effect of both on-site electronic voting and Internet voting on non-resident citizens’ voter turnout. This paper shows that, while on-site electronic voting seems to have no significant impact on turnout, turnout of non-resident citizens using Internet voting significantly increased as compared to prior elections and to neighboring electoral districts.
Direct Sliding Mode Control for Dynamic Instabilities in DC-Link Voltage of Standalone Photovoltaic Systems with a Small Capacitor

Large electrolytic capacitors used in grid-connected and stand-alone photovoltaic (PV) applications for power decoupling purposes are unreliable because of their short lifetime. Film capacitors can be used instead of electrolytic capacitors if the energy storage requirement of the power conditioning units (PCUs) is reduced, since they offer better reliability and have a longer lifetime. Film capacitors have a lower capacitance than electrolytic capacitors, causing enormous frequency ripples on the DC-link voltage and affecting the standalone photovoltaic system’s dynamic performance. This research provided novel direct sliding mode controllers (DSMCs) for minimizing DC-link capacitor, regulating various components of the PV/BES system that assists to manage the DC-link voltage with a small capacitor. DSMCs were combined with the perturb and observe (P&O) method for DC boost converters to increase the photovoltaic system’s dynamic performance, and regulate the battery’s bidirectional converter (BDC) to overcome the DC-link voltage instabilities caused via a lower DC-link capacitor. The system is intended to power both AC and DC loads in places without grid connection. The system’s functions are divided into four modes, dependent on energy supply and demand, and the battery’s state of charge. The findings illustrate the controllers’ durability and the system’s outstanding performance. The testing was carried out on the MT real-time control platform NI PXIE-1071 utilizing Hardware-In-The-Loop experiments and MATLAB/Simulink.
Molecular Authentication, Propagation Trials and Field Establishment of Greek Native Genotypes of Sambucus nigra L. (Caprifoliaceae): Setting the Basis for Domestication and Sustainable Utilization

In the context of sustainable utilisation of valuable but neglected plant resources, a multifaceted study is presented herein for Greek native genotypes of elderberry (Sambucus nigra L., Caprifoliaceae), a species with an appreciated pharmaceutical and nutritional value. At the first phase, fresh plant materials (leaves, softwood cuttings) were collected from nine geographically separated genotypes originating from wild-growing Greek native germplasm of S. nigra. The leaf samples were genetically authenticated using DNA barcoding (ITS2). The next phase included the development of an asexual propagation protocol via cuttings which included screening of the collected genotypes in terms of propagation success, and further experimentation over a two-year period on a prioritised genotype. The propagation results highlighted the importance of external application of indole-3-butyric acid (IBA) rooting hormone at levels of 2000–4000 ppm, which consistently presented high rooting rates (100%) of summer softwood, leafy cuttings of apical or sub-apical type. At the same time, rooting quality in terms of root number and length as well as early plant growth after rooting, were improved by external hormone application resulting in high rates of plant survival. This study reports first-time data on multifaceted assessment of Greek native S. nigra genotypes on molecular authentication and asexual propagation, thus ultimately setting the basis for domestication and sustainable utilization of this species.
Coastal Trapped Waves Generated By Hurricane Andrew on the Texas-Louisiana Shelf

Coastal Trapped Waves Generated by Hurricane Andrew on the Texas-Louisiana Shelf. (December 2011) Stuart Michael Pearce, B.S., Auburn University Chair of Advisory Committee: Dr. Steven F. DiMarco The Texas-Louisiana Shelf Circulation and Transport Study featured moorings that covered the shelf during 1992 to 1994, and captured the oceanic response on the shelf to category 4 Hurricane Andrew in August of 1992. Eighty-one current meters distributed over 31 moorings along several contours of isobaths provided excellent spatial and temporal coverage over the shelf. The low-frequency variability (2 days and longer) of current observations and tide gauges to the West of the storm are analyzed after the passage of Andrew, focusing on the region outside of direct hurricane forcing. Wavelet analyses are utilized to investigate the dominant periods excited by the storm over the shelf and their temporal evolution after forcing has subsided. Subsequent to the storm’s passage, the observations and wavelet transforms show a two-to-four day period coastal trapped wave that propagate westward at speeds near 6 m/s and then around the Texas bend along the bathymetry. The signal remains detectable in observations as far south as Port Isabel, Texas. The prominent frequencies determined from wavelet analysis are compared with predicted coastal trapped wave dispersion modes and show good agreement in the predicted group speed and cross-shelf structure of the first mode. The energies calculated from the data indicate a largely barotropic shelf wave response which is corroborated in the observed currents and by theory.
Breaking waves on beaches

A comprehensive experimental study has been carried out to measure the velocity field of waves breaking on two types of beach. The measurement technique of Particle Image Velocimetry (PIV) has been used throughout to measure the fullfield, instantaneous velocity distributions. This technique is described in some detail with particular attention paid to the errors inherent when using PIV in this application. The first type of beach studied has a mild slope, typical of sandy beaches. PIV measurements have been carried out on 1:30 and 1:100 plane sloping beaches with monochromatic waves. The measured internal kinematics are compared to those predicted by the Boussinesqand Serre-type wave models, with some good agreement. However, there are some significant differences in the nearsurface region of the wave crest which tend to increase as the waves propagate up the beach. In addition to these theoretical comparisons, the Integral Properties of the waves on the 1:30 slope are calculated from the PIV measurements. The second type of beach examined is typical of a shingle beach. In addition to being steeper than the previous case, these beaches are also profiled, representing the shape of the beach formed under storm conditions. Two profiles have been modelled and three different monochromatic waves have been measured on each. The wave breaking processes are described and velocity measurements from each wave on both beaches are shown. Furthermore, a near-bed velocity comparison between the three waves at various positions along each beach has also been carried out in order to explain any potential on-shore and off-shore sediment motion.
Ameliorative Effect of Pu-erh Tea on DSS-induced Colitis through Regulation of NF-κB Activation in Mice

Ulcerative colitis (UC), chronic inflammatory bowel disease, is characterized by severe inflammation in the colon. Tea is one of the most popular beverages consumed worldwide. Pu-erh tea, a unique Chinese tea produced by microbial activities, possesses a broad range of health-promoting effects, including anti-aging, anti-Alzheimer's disease, anti-oxidation and anti-obesity. However, the inhibitory effect of Pu-erh tea on intestinal inflammation and the underlying mechanism remain unclear. The present study was designed to evaluate the regulatory effect of Pu-erh tea extract (PTE) on dextran sulfate sodium (DSS)-induced colitis clinical signs by analyzing the weight loss and colon length in mice. The inhibitory effects of PTE on inflammatory mediators, such as interleukin (IL)-6 and tumor necrosis factor (TNF)-α, and the activation of nuclear factor-κB (NF-κB) were also determined in DSS-treated colitis tissue. We observed that PTE treatment significantly inhibited the DSS-induced clinical symptoms of weight loss, decrease,in colon length, and colon tissue damage in mice. Moreover, PTE attenuated the DSS-induced levels of IL-6 and TNF-α in colon tissue. We also demonstrated the anti-inflammatory mechanism of PTE by suppressing the activation of NF-κB in DSS-treated colon tissues. Collectively, the findings provide experimental evidence that PTE may be effective in preventing and treatment of intestinal inflammatory disorders, including UC.
Experimental study of the dispersion of cough-generated droplets from a person going up- or downstairs

The dispersion of cough-generated droplets from a person going up- or downstairs was investigated through a laboratory experiment in a water tunnel. This experiment was carried out with a manikin mounted at inclination angles facing the incoming flow to mimic a person going up or down. Detailed velocity measurements and flow visualization were conducted in the water tunnel experiments. To investigate the influence of the initial position on the motion of particles, a virtual particle approach was adopted to simulate the dispersion of particles using the measured velocity field. Particle clustering, which is caused by the unsteadiness of the flow, was observed in both flow visualization and virtual particle simulation. For the case of going upstairs, particles are concentrated below the person’s shoulder and move downward with a short travel distance. For the case of going downstairs, particles dispersing over the person’s head advect over for a long distance. We also found that the motion of the particles is closely related to the initial position. According to the results in this study, suggestions for the prevention of respiratory infectious disease are made.
