Published: June 2022

Background: Amongst all other educational institutions, medical schools suffered the consequences of the COVID-19 pandemic. Medical education requires a great deal of interaction between instructors and students, and in the final years, patients as well. In response to the pandemic, the College of Medicine and Medical Sciences at the Arabian Gulf University has applied virtual teaching/ learning since March 2020 as an alternative to face-to face teaching. The college used Moodle and Zoom as online methods for education. The aim of the present study was to evaluate the effectiveness of virtual medical education by comparing students’ performance in final exams in face-to-face and virtual settings. Methods: Following the college’s ethical approval, this longitudinal study was performed on 183 medical students. Those students experienced 2 different successive methods of teaching/learning; Unit V as face-to-face followed by Unit VI as virtual settings. Students’ performance in theoretical component of the final exams for both units was analyzed and compared. Results: There was no significant difference in student performance between Units V and VI. Students’ performance in the physiology part was equally effective in both units, while the difficulty index of both exams was insignificantly different. Conclusion: Our results demonstrate that students’ performance in final exams could serve as an objective parameter when comparing different educational settings. Our results also support the idea that, in certain aspects, virtual is equal to face-to-face medical education strategies.

Published: June 2022

The wastewater pH neutralization process from a wastewater treatment plant is one of the most important processes from a plant chemical step, having a strong nonlinearity and also a dynamic behavior. The multiple emergency situations that can occur in the pH neutralization process operating affects the biological processes with undesirable consequences on the plant emissary. So, the real-time information of a plant human operator regarding the problems that occur in the pH neutralization process is absolutely necessary for the optimal treatment process operating and problems prevention. The paper presents an Android application for real-time information of the wastewater pH human operator, application that uses React Native v.0.64 technology, PHP and MySQL languages. The developed application has a number of component modules (the authentication module, the process monitoring module and the module for real-time information (warning) of the process human operator), modules that works both on Android and iOS devices. The main advantage of the application is that it provides in real-time a detailed warning report for the process human operator, report that can be access by the operator on his Android device and used later in similar situations in order to take the best decisions. A set of simulation results related to the developed application is also presented, for different process disturbances.

A Single Parameter Hygroscopicity Model for Functionalized and Insoluble Aerosol Surfaces
Authors: Mao Chun-Ning , Gohil Kanishk , Asa-Awuku Akua
Published: June 2022

Abstract. The impact of molecular level surface chemistry for aerosol water-uptake and droplet growth is not well understood. In this work, spherical, non-porous, monodisperse Polystyrene Latex particles treated with different surface functional groups are exploited to isolate the effects of aerosol surface chemistry for droplet activation. PSL is effectively water-insoluble and changes in the particle surface may be considered a critical factor in the initial water-uptake of water insoluble material. The droplet growth of two surface modified types of PSL (PSL-NH2 and PSL-COOH) along with plain PSL was measured in a supersaturated environment with a Cloud Condensation Nuclei Counter (CCNC). Three droplet growth models - traditional Köhler (TK), Flory-Huggins Köhler (FHK) and the Frenkel-Halsey-Hill adsorption theory (FHH-AT) were compared to experimental data. The experimentally determined single hygroscopicity parameter, κ, was found in the range from 0.002 to 0.04. The traditional Köhler prediction assumes Raoult’s law solute dissolution and underestimates the water-uptake ability of the PSL particles. FHK can be applied to polymeric aerosol; however, FHK assumes the polymer is soluble and hydrophilic. Thus, the FHK model generates a negative result for hydrophobic PSL and predicts non-activation behavior that disagrees with the experimental observation. The FHH-AT model assumes that a particle is water-insoluble and can be fit with 2 empirical parameters (AFHH and BFHH). The FHH-AT prediction agrees with the experimental data and can differentiate the water uptake behavior of the particles due to surface modification of PSL surface. PSL-NH2 exhibits slightly higher hygroscopicity than the PSL-COOH, while plain PSL is the least hygroscopic among the three. This result is consistent with the polarity of surface functional groups and their affinity to water molecules. Thus, changes in AFHH and BFHH can be quantified when surface modification is isolated for the study of water-uptake. The fitted AFHH for PSL-NH2, PSL-COOH and plain PSL is 0.23, 0.21 and 0.18 when BFHH is unity. To simplify the use of FHH-AT for use in cloud activation models, we also present and test a new single parameter framework for insoluble compounds, κFHH. κFHH is within 5 % agreement of the experimental data and can be applied to describe a single-parameter hygroscopicity for water-insoluble aerosol with surface modified properties.
Spatio-temporal variation of radionuclide dispersion from nuclear power plant accidents using FLEXPART ensemble modeling

Published: June 2022

Abstract. We estimate the seasonal and diurnal changes in the transport and intensity of radionuclides including Iodine-131 (131I) and Cesium-137 (137Cs), transported to Qatar from a fictitious accident at the Barakah nuclear power plant (B-NPP) in UAE. For dispersion modeling, we have used the Lagrangian particle/air parcel dispersion model FLEXible PARTicle (FLEXPART) driven by forecast and (re)analysis products, and coupled with the Weather Research and Forecasting model (FLEXPART-WRF). A four-member ensemble of meteorological inputs, including one forecast dataset (CFSv2) and three (re)analysis datasets (native resolution and downscaled FNL and downscaled ERA5), is used to force FLEXPART/FLEXPART-WRF. According to the age spectrum of Lagrangian particles, radionuclides entered southern Qatar about 10 to 20 hours after emission, and almost all emitted particles are transported to and/or deposited in the study area within the 80 hours after the release. A higher number of long-lived particles was found in FNL simulations and when particles are released in the afternoon and spring. The highest levels of simulated 131I concentrations and 137Cs deposition were found in FNL simulations in the south/southeast of Qatar. The frequent coincidence of high radionuclide concentrations and deposition with particles released between 5 a.m. and 2 p.m. and in the cold period of the year was attributed to diurnal and seasonal changes in the planetary boundary layer height (PBLH) and synoptic circulations. The difference in input PBLH explains well the inter-member variations of simulated radionuclide concentrations. Simulated concentrations were found with the same level of consistency as reported for real case studies.
A machine learning approach to quantify meteorological drivers of ozone pollution in China from 2015 to 2019
Authors: Weng Xiang , Forster Grant L. , Nowack Peer
Published: June 2022

Abstract. Surface ozone concentrations increased in many regions of
China from 2015 to 2019. While the central role of meteorology in modulating
ozone pollution is widely acknowledged, its quantitative contribution
remains highly uncertain. Here, we use a data-driven machine learning
approach to assess the impacts of meteorology on surface ozone variations in
China for the period 2015–2019, considering the months of highest ozone pollution
from April to October. To quantify the importance of various meteorological
driver variables, we apply nonlinear random forest regression (RFR) and
linear ridge regression (RR) to learn about the relationship between
meteorological variability and surface ozone in China, and contrast the
results to those obtained with the widely used multiple linear regression
(MLR) and stepwise MLR. We show that RFR outperforms the three linear
methods when predicting ozone using local meteorological predictor
variables, as evident from its higher coefficients of determination
(R2) with observations (0.5–0.6 across China) when compared to the
linear methods (typically R2 = 0.4–0.5). This refers to the importance of
nonlinear relationships between local meteorological factors and ozone,
which are not captured by linear regression algorithms. In addition, we find
that including nonlocal meteorological predictors can further improve the
modelling skill of RR, particularly for southern China where the averaged
R2 increases from 0.47 to 0.6. Moreover, this improved RR shows a
higher averaged meteorological contribution to the increased trend of ozone
pollution in that region, pointing towards an elevated importance of
large-scale meteorological phenomena for ozone pollution in southern China.
Overall, RFR and RR are in close agreement concerning the leading
meteorological drivers behind regional ozone pollution. In line with
expectations, our analysis underlines that hot and dry weather conditions
with high sunlight intensity are strongly related to high ozone pollution
across China, thus further validating our novel approach. In contrast to
previous studies, we also highlight surface solar radiation as a key
meteorological variable to be considered in future analyses. By comparing
our meteorology based predictions with observed ozone values between 2015
and 2019, we estimate that almost half of the 2015–2019 ozone trends across
China might have been caused by meteorological variability. These insights
are of particular importance given possible increases in the frequency and
intensity of weather extremes such as heatwaves under climate change.
Soil Cycles of Elements simulator for Predicting TERrestrial regulation of greenhouse gases: SCEPTER v0.9
Authors: Kanzaki Yoshiki , Zhang Shuang , Planavsky Noah J. , Reinhard Christopher T.
Published: June 2022

Abstract. The regulation of anthropogenic carbon dioxide (CO2) is an urgent issue – continuously increasing atmospheric CO2 from burning
fossil fuels is leading to significant warming and acidification of the
surface ocean. Timely and effective measures to curb CO2 increases are
thus needed in order to mitigate the potential degradation of natural
ecosystems, food security, and livelihood caused by anthropogenic release of
CO2. Enhanced rock weathering (ERW) on croplands and hinterlands may be
one of the most economically and ecologically effective ways to sequester
CO2 from the atmosphere, given that these soil environments generally
favor mineral dissolution and because amending soils with crushed rock can
result in a number of co-benefits to plant growth and crop yield. However, robust quantitative evaluation of CO2 capture by ERW in terrestrial soil systems that can lead to coherent policy implementation will require an ensemble of traceable mechanistic models that are optimized for simulating ERW in managed systems. Here, we present a new 1D reactive transport model – SCEPTER. The model is designed to (1) mechanistically simulate natural weathering, including dissolution/precipitation of minerals along with
uplift/erosion of solid phases, advection plus diffusion of aqueous phases
and diffusion of gas phases, (2) allow targeted addition of solid phases at the soil–atmosphere interface, including multiple forms of organic matter
(OM) and crushed mineral/rock feedstocks, (3) implement a range of soil mixing regimes as catalyzed by soil surface fauna (e.g., bioturbation) or
humans (e.g., various forms of tilling), and (4) enable calculation of solid mineral surface area based on controlled initial particle size distributions
coupled to a shrinking core framework. Here we describe the model structure
and intrinsic thermodynamic/kinetic data, provide a series of idealized
simulations to demonstrate the basic behavior of the code, and evaluate the
computational and mechanistic performance of the model against observational
data. We also provide selected example applications to highlight model
features particularly useful for future prediction of CO2 sequestration
by ERW in soil systems.
The Mission Support System (MSS v7.0.0) and its use in planning for the SouthTRAC aircraft campaign

Published: June 2022

Abstract. The Mission Support System (MSS) is an open source software package that has been used for planning flight tracks of scientific aircraft in multiple measurements campaigns during the last decade. It consists of three major components: a web map server located close to the model data storage site that is capable of producing a variety of 2-D figures from 4-D meteorological data; a client application capable of displaying the figures in combination with the planned flight track and an assortment of additional information; a new collaboration server component that enables real-time collaboration of multiple remote parties. During the last decade, these components were constantly improved towards being simple to setup and use and standard compliant. Here, we describe the use of MSS during the SouthTRAC measurement campaign in 2019. This campaign, based in Rio Grande, Argentinia, used the German research aircraft HALO to investigate several scientific objectives related to the Southern Hemisphere chemistry and dynamics. We present the diverse data products offered by the MSS web map server dedicated to the campaign, which were derived from European Centre for Medium-Range Weather Forecasts (ECMWF) forecast data, Chemical Lagrangian Model of the Stratosphere (CLaMS) simulations, and Atmospheric Infrared Sounder (AIRS) near-realtime brightness temperature measurements. As example for how the MSS software is used in conjunction with the different data sets, we describe the planning of a single flight, which eventually took place on the 12th of September 2019, probing orographic gravity waves propagating up into the lower mesosphere.
How much can be taught about stochastic processes and to whom?
Authors: Wang Ann-Lee
Published: June 2022

Researchers quite often need to model and analyse real-world random phenomena using stochastic processes. Learning stochastic processes requires a good knowledge of the probability theory, calculus, matrix algebra and a general level of mathematical maturity. However, not all researchers have a good foundation in probability and mathematics. In this paper, we discuss the different approaches to the teaching of a first course in stochastic processes to researchers. Difficulties in the understanding of stochastic processes and the various mathematical techniques used in stochastic processes are discussed. Proposal for the core topics of such a course and ways of teaching them are put forward.
Practical and educational problems in sharing official micro data with researchers
Authors: McDonald Sandra
Published: June 2022

Many commentators have noted the need for reform in statistical education. They tend to focus on the analytical techniques that are critical to understanding and producing good quality statistical outputs. This paper adds to these discussions and looks at some of the main analytical issues that transpire from researchers accessing the particular form of statistical data sets in a national statistical office. However the conclusions are much more widely applicable to other data sets. It also considers the more practical, but very important skills and knowledge, applicable to all types of data, that a researcher needs, such as fashioning the data set into a format that is most useful to them, and ensuring they obtain access to data that will allow them to fulfil their research objectives.
What do students gain from simulation exercises? An evaluation of activities designed to develop an understanding of the sampling distribution of a proportion
Authors:   Swinburne University of Technology, Lipson Kay
Published: June 2022

The trend in statistics education over the past few years has been to replace extensive studies in probability, which lead to the theoretical development of the probability distribution, with computer-based simulation exercises that develop these ideas based on empirical results. This trend has been supported strongly by the statistics education community in general (e.g., Biehler, 1985; Gordon & Gordon, 1992; Hogg, 1992; Moore, 1992b) . In some cases, entire courses have been developed based on computer-based simulation (e.g., Martin, Roberts, & Pierce, (1994). Although this movement away from formal studies in probability could be well-founded, little formal research has been undertaken to determine the sort of understanding that develops as a result of such computer-based simulation exercises.
Examining the educational potential of computer-based technology in statistics
Authors:   Swinburne University of Technology, Jones Peter
Published: June 2022

By its very nature, statistics is a computationally intensive endeavor. The hand calculation of a correlation coefficient, such as the Pearson product moment correlation coefficient, is tedious, extremely time consuming, and has great potential for computational error. To assist with the task and reduce the potential for error, methods have been developed that reduce the computation to the completion of a carefully constructed table (e.g., Moore & McCabe, 1993). With the advent of statistical packages and, more recently, scientific calculators with statistical functions, students with routine access to such technology have no need to master such computational procedures. Yet textbooks are now being written that promote the use of spreadsheets to replicate such computations (Daly, Cody, & Watson, 1994), despite the fact that the same spreadsheet, once the data has been entered, will calculate the value of the required statistic on demand!

Flavanol compounds are chalcone derivatives, generally found in hydroxy substituted forms that can act as ligands. Hydroxy-substituted flavonols are found in many plants but in very small amounts. In order to enrich and expand the use of this compound as a ligand, the synthetic methods were carried out through structural variations, one of which was by substitution using chloride and then the compound (2-(4-chlorophenyl)-3-hydroxy-4H-chromene-4-one) was obtained. In this research, the study was conducted using the compound (2-(4-chlorophenyl)-3-hydroxy-4H-chromene-4-one) as a ligand for complex formation with copper (II). From the results of the study, the mole ratio of the ligand with copper (II) metal was 2:1, pH 7.01 with a complex stability time of 15-25 minutes. The complex formed is bright yellow in color and soluble in chloroform. From the characterization of the resulted complex, it was appeared that Cu-flavonol chloride with UV-Vis spectrophotometer showed maximum absorption at wavelengths 273 and 429 indicating the presence of benzoyl and cinnamoyl peaks, with FT-IR showing the wave number 1545cm-1 indicating the presence of Cu=O-Cu bonds and absorption at 682 cm-1 indicating the presence of Cu-O bonds.
Experimental study on the interaction of insulin with apatitic calcium phosphates analogous to bone mineral: adsorption and release
Authors: Rhilassi Abdelhadi El , Bennani-Ziatni Mounia
Published: June 2022

The present work investigated the interaction of human insulin with synthesized poorly crystalline apatitic calcium phosphates containing simultaneously HPO42- and CO32- ions in various amount. The adsorption kinetics is very fast, while the release kinetics is generally slow. The chemical composition of apatite has an influence on both the adsorption and release processes. The experimental results show that the percentage of insulin adsorption and release decreased with the increase of the content of carbonate. The equilibrium adsorption data are fitted into Langmuir, Freundlich, Elovich, Temkin, and Dubinin–Radushkevich isotherms. The Langmuir model is best suited with a maximum monolayer adsorption capacity of 33.20 and 25.08 mg/g at 310 K corresponding to the carbonated and octocalcium phosphate apatite respectively. Isotherms parameters have revealed that the adsorption of insulin on these apatites is a feasible, spontaneous, and exothermic process. Fourier-transforms infrared confirm the fixation of insulin on non-carbonated and carbonated apatite. The adsorption and release of insulin molecules can be well described as an ions exchange-reaction between species in the hydrated layer of apatite and other species in solution. All of these results suggested that apatitic calcium phosphates can be used as systems for insulin delivery.

Authors: Flötteröd Yun-Pang , Behrisch Michael
Published: June 2022

Currently, the city of Huainan, China, is constructing its intelligent transportation system, and traffic and environmental monitoring system for efficiently and effectively monitoring and managing city traffic. DLR’s traffic information platform KeepMoving is adopted in the aforementioned system, where the existing online calibration module with SUMO has been extended in order to provide current and predicted traffic states and the resultant emission information in real-time. Accordingly, a comprehensive city-wide traffic situation can be captured and shown at the KeepMoving portal, as a decision support tool for traffic management personnel. The comparison between the real and simulated data shows a promising calibration result.
A Study of Applying Eco-Driving Speed Advisory System on Transit Signal Priority
Authors: Wang Hsuan-Chih
Published: June 2022

Transit Signal Priority (TSP) has long been seen as a cost-effective way to reduce bus delays at intersections. With Connected Vehicle (CV) technology, a speed advisory system guides buses to pass intersections in an energy-saving way. The integration of TSP and speed advisory may reduce bus delays and enhance energy consumption performances. This study proposed a system of integrating eco-driving speed advisory on TSP under CV environment. A TSP strategy based on intersections passing probability is designed. In addition to signal priority, this study designed and implemented an eco-driving speed advisory algorithm. A real electric bus route in Tainan City, Taiwan is used for the case study. Intersection layout and traffic related parameters are established in microscopic traffic simulation software SUMO (Simulation of Urban Mobility) to verify the effectiveness of the proposed model. The results provide an insight into how cooperation between signals and vehicles can enhance performances of energy consumption and signal-incurred traffic delays.

Bu çalışmada, çilekte hasat öncesi ve hasat sonrası ürün kayıplarına neden olan Botrytis cinerea’ya karşı Iğdır ilinde tuzlu topraklardan ve Phragmites australis bitkisinden izole edilen bakteri strainlerinin antagonistik özellikleri araştırılmıştır. Yapılan izolasyonlar neticesinde 89 bakteri straini elde edilmiş ve bu bakterilerin tanıları yağ asit metil ester analizi ile yapılmıştır. Elde edilen bakteriler arasında 38 strain in vitro testlerde etkili bulunmuş ve bu strainlerin B. cinerea’nın misel gelişimini farklı oranlarda engelledikleri tespit edilmiştir. Başarılı olan strainler cins düzeyinde değerlendirildiğinde Bacillus ve Paenibacillus cinslerinin daha etkili oldukları belirlenmiştir. Çalışmada kullanılan aday antagonistlerin inhibisyon oranlarına bakıldığında en etkili strainin %71.68 oranı ile Bacillus subtilis MFD2-21 olduğu, bu straini %68.89 oranı ile Paenibacillus polymyxa MFD-15 ve %61.93 oranı ile Paenibacillus apiarus MFD20 straininin takip ettiği belirlenmiştir. B. cinerea’nın misel gelişimini en düşük oranda engelleyen aday antagonist strain ise %17.36 oranı ile Bacillus sphaericus GC subgroup E MFD3-15 olarak saptanmıştır.

Memory for Gaze Cues Can Attenuate Change Blindness in the Flicker Paradigm
Authors: Miller Alexis , Tolliver Joshua , Varakin Alex
Published: June 2022

Introduction: Observers often pay attention to objects that are the target of another’s gaze.  The current experiments investigate if memory for gaze cues has similar effects on attention.
Methods:  We used the flicker paradigm, in which participants searched for changes in pictures of real-world scenes. In experiment 1, half of the scenes depicted a person looking at the changing object, and the other half depicted no people. In experiment 2, none of the scenes in the flicker sequence contained people, but participants previewed pictures prior to the flicker sequence, and half of the previews depicted a person looking at the changing object.
Results: In both experiments, participants were faster to find changes when the changes were cued (Exp 1, t(20) = 2.55, p = .02; Exp 2, t(49) = 7.18, p < .001). Analysis of accuracy suggests it was not due to a speed-accuracy tradeoff. 
Conclusions: These results suggest that memory for gaze cues may help guide attention. However, the results do not suggest one way or the other whether this effect is reflexive or unique to social cues.
USO DE METODOLOGIAS ATIVAS NA CONSTRUÇÃO DE DIAGNÓSTICOS DE ENFERMAGEM POR ACADÊMICOS
Authors: Gomes Adenilson da Silva , Santos Gabrielle Morgana Rodrigues dos
Published: June 2022

Introdução: As Metodologias Ativas no campo da saúde contribuem para a motivação e despertam a curiosidade nos alunos ao passo que esses se inserem na teorização e despertam para novos elementos em sua formação em saúde. Objetivo: relatar a experiência do uso de metodologias ativas por acadêmicos de enfermagem na elaboração de diagnósticos de enfermagem. Métodos: Trata-se de um relato de experiência, com abordagem quantitativa, descritiva e exploratória, realizado entre os meses de outubro a dezembro de 2020. Sob ensino remoto, utilizou-se um estudo de caso como atividade avaliativa e, a partir dele, solicitou-se a elaboração de diagnósticos de enfermagem. Estes, uma vez submetidos, serviram como base de avaliação discente e tornaram material de análise para execução desse relato analisando-os via Microsoft Excel® 2016 sob abordagem descritiva básica dos títulos, da estrutura dos Padrões Funcionais mediante Taxonomia da NANDA-I e dos fatores relacionados e características definidoras. Resultados e Discussão: foram construídos diagnósticos de enfermagem com foco no problema elencados a partir de prioridades com base em evidências clínicas e não meramente por suposições. Esses diagnósticos pertenciam com mais frequência aos domínios de ‘atividade/repouso’ (54,1%), ‘percepção/cognição’ (17,6%) e ‘segurança/proteção’ (12,2%). Em relação aos fatores relacionados e as características definidoras de cada diagnóstico pôde-se perceber que houve associação de informações clínicas no processo de interpretação diagnóstica pautado na dialética ação-reflexão. Conclusão: Evidenciou-se que a criação de diagnósticos de enfermagem com base em metodologias ativas aprimora saberes e práticas nos discentes que os permitem capacitá-los em torno de sua formação para o desenvolvimento de uma atuação condizente com as exigências do mercado de trabalho.
