A machine learning-based QSAR model for predicting phenols cytotoxicity
Authors: Douali Latifa
Published: April 2022

Cytotoxicity is a very important aspect that gains big research interest in toxicology and pharmacology as it is related to whether a compound may cause cell damage, necrosis or apoptosis and this contributes effectively to determine the toxicity potential of a compound and to cancer treatment studies as well. The complexity and the sensitivity of cytotoxicity assays and the involvement of animal tests in many instances increase the need for rapid and reliable alternative methods. Quantitative structure-activity relationships (QSAR) are relevant techniques that provide mathematical models and help in chemicals screening and in predicting biological activities and eventually cytotoxicity. Because of their capacity to handle complex problems, machine learning contributed substantially to the QSAR field's evolvement. In this study, we established a predictive QSAR model based on machine learning, namely deep neural network to predict the cytotoxicity of phenols. The model exhibited high performances in predicting new compounds. It was proved that hydrophobic, steric and electronic effects are relevant in determining the cytotoxicity variability of phenols against Tetrahymena pyriformis.

Authors: P. Ocampo Myda Rose , P. Del Rosario Anna Liza
Published: April 2022

Problem-solving skill refers to the ability to solve difficulties efficiently and without hindrances. It entails identifying and defining the problem, developing a strategy, creating different solutions, evaluating and selecting the best alternative, implementing the chosen solution, and re-checking the solution by reviewing the process. Learning how to translate situations, tables, graphs, and formulas (symbolic) is a big help in creating differentiated activities that will help students improve their problem-solving skills. To back up this claim, this study included the use of translation action in a prepared instructional material and evaluated its impact on increasing students' problem-solving abilities. During the academic year 2020-2021, thirty (30) Grade five students participated in the study, which used a one group pre-test and post-test research design to achieve the study's aims. The results revealed a substantial difference between the student-respondents' pre-test and post-test performance, implying that the translation activity aided students in improving their problem-solving abilities. This means that they were able to reach suitable mastery to mastery level of performance from the beginning to the end of the problem-solving process. In addition, in this time of pandemic, the usage of the designed instructional material encourages students to participate in more activities. Teachers should utilize the translation-based instructional material as an additional worksheet, according to the study, because it can assist students improve their mathematics skills and talents in answering word problems.

Published: April 2022

The construct of resilience is usually entered into statistical models as an independent variable even though scholars assert it should be conceptualised similarly to other post-trauma mental health outcomes (Kalisch et al., 2017). To the best of our knowledge, there are no other published papers using a dependent variable from a standardised resilience assessment and individual trauma exposure item-level responses as predictor variables. 93 Emergency Medical Service (EMS) professionals completed the Life Events Checklist (LEC) and the Brief Resilience Scale (BRS). Each response to all LEC questions was entered into a backwards stepwise regression predicting resilience. The backwards stepwise regression was significant F(7, 85) = 9.14, p < .001 and accounted for 38.3% of the variability in resilience. Gender and LEC items 3, 10, 12, and 13 negatively predicted resilience, whereas prior military service and LEC item 14 (sudden violent death) increased resilience. Even 20 months into the COVID-19 pandemic, EMS professionals continued to serve their communities. Surprisingly, sudden violent death significantly increased resilience (β = .43, p < .001). We concur with scholarship on EMS professionals (before and during the pandemic) that resilience should be thought of as applied when needed (Carbajal et al., 2021; Ponder et al., 2022).
Measuring affect dynamics: An empirical framework
Authors: Pirla Sergio , Taquet Maxime , Quoidbach Jordi
Published: April 2022

A fast-growing body of evidence from experience sampling studies suggests that affect dynamics are associated with well-being and health. But heterogeneity in experience sampling approaches impedes reproducibility and scientific progress. Leveraging a large dataset of 7016 individuals, each providing over 50 affect reports, we introduce an empirically derived framework to help researchers design well-powered and efficient experience sampling studies. Our research reveals three general principles. First, a sample of 200 participants and 20 observations per person yields sufficient power to detect medium-sized associations for most affect dynamic measures. Second, for trait- and time-independent variability measures of affect (e.g., SD), distant sampling study designs (i.e., a few daily measurements spread out over several weeks) lead to more accurate estimates than close sampling study designs (i.e., many daily measurements concentrated over a few days), although differences in accuracy across sampling methods were inconsistent and of little practical significance for temporally dependent affect dynamic measures (i.e., RMSSD, autocorrelation coefficient, TKEO, and PAC). Third, across all affect dynamics measures, sampling exclusively on specific days or time windows leads to little to no improvement over sampling at random times. Because the ideal sampling approach varies for each affect dynamics measure, we provide a companion R package, an online calculator (https://sergiopirla.shinyapps.io/powerADapp), and a series of benchmark effect sizes to help researchers address three fundamental hows of experience sampling: How many participants to recruit? How often to solicit them? And for how long?

Published: April 2022

The optical and biological properties of the tunable functionalized gold nanoparticles (GNPs) tuned have been widely used in the sensing applications. GNPs have a strong binding ability to sulfhydryl groups of thiols. Furthermore, thiols is used as mediators to modify functional molecules to adjust their performance, which can be used to detect metal ions in solution. Herein, we demonstrated the 13 nm GNPs were functionalized by glutathione (GSH) and conjugated by rhodamine 6G derivatives (Rh6G2) which can be used to detect of Hg(II) in cells. The detection of Hg2+ is based on the ion-catalyzed hydrolysis reactions of the spiroamide ring of Rh6G2, leading to a significant change in the fluorescence of GNPs-GSH-Rh6G2 from “OFF” to “ON” due to the triggered release. The designed strategy is an effective tool to detect Hg2+. In cytotoxicity experiments, GNPs-GSH-Rh6G2 can penetrate living cells and recognize mercury ions through the fluorescent "ON" form.

EFFECT OF COMPACTION TIME WITH VIBRATING HAMMER ON STRENGTH PROPERTIES IN ROLLER COMPACTED CONCRETE
Authors: KILIÇ İsmail
Published: April 2022

Roller compacted concrete (RCC) production in the laboratory using a vibrating hammer is one of the methods used in research studies. In this method, it is thought that the compaction time will change the strength properties of the RCC samples. For this reason, it is aimed to determine the ideal compaction time in terms of strength by producing RCC samples with different compaction times. In the experimental study, RCC samples with the same mixture design were compacted with a vibrating hammer for 5, 10, 15 and 20 seconds at different times. Compactibility percentage, unit weight, water absorption, ultrasonic pulse velocity and 28-day concrete compressive strength tests were carried out on the produced roller compacted concrete samples. In the study, it was determined that the void ratio in the roller compacted concrete samples decreased with the increase of the compaction time. The highest strength value was obtained from the RCC sample, which was compressed for 15 seconds. It has been emphasized that the design of the roller compacted concrete mix and especially its consistency will affect the ideal compaction time in terms of strength.

Authors: KAYIN Sercan , İŞSEVEN Turgay
Published: April 2022

As a result of the convergence between the Arabian plate and the Anatolian block, a continentcontinent collision occurred in the region along the Bitlis Zargos sutur zone. Following the collision, volcanic activity began in the Late Miocene and produced volcanic material throughout the region and reach to the Caucasus. Collision-related volcanism in eastern Anatolia covered almost two-thirds of the area and formed volcanic products up to 1 km thick. In order to determine the tectonic evolution of Mount Nemrut and its around, paleomagnetic core samples were collected from a total of 11 sites from Pleistocene - Holocene time interval aged volcanic rocks. Paleomagnetic laboratory studies were carried out in KANTEK Paleomagnetism Laboratory, and also rock magnetism studies were carried out in Istanbul University-Cerrahpaşa, Yılmaz İspir Paleomagnetism Laboratory. When the mean magnetization directions obtained from Mount Nemrut and its surrounding Holocene and Upper Pleistocene aged locations are examined, it is seen that there is an average of 7.3° clockwise rotation. It is also observed that the angle of inclination is 60°. These results obtained, considering the α95 circle (7.7°), it is observed that there is no tectonic rotation within the sensitivity limits of paleomagnetism in the region. At the same time, it can be interpreted that Mount Nemrut has not been exposed to a latitudinal movement since the Quaternary, but volcanics is still at the latitude where it was formed.
INVESTIGATION THE EFFECT OF pH VALUE IN GRAPHENE OXIDE PRODUCTION
Authors: KANBUR Kürşat , BİRLİK Işıl , SARGIN Fatih , AK AZEM N. Funda , TÜRK Ahmet
Published: April 2022

In recent years, the use of graphene oxide (GO) in advanced application areas has attracted great interest. GO consists of a carbon basal plane containing various functional groups. Thanks to its properties, GO can improve the properties of the materials to which it is added. Therefore, GO is used in various photocatalytic, sensor and battery applications. Moreover, large-scale production of graphene, which has outstanding propertiessuch as high electrical conductivity, thermal conductivity, and high surface area, is possible by reduction of GO. Therefore, quality and controllable GO production is required. GO is generally produced with the Hummer's Method, which is a suitable chemical method for industrial production. In Hummer's Method, graphite oxide is obtained by oxidizing of graphite with the help of oxidizing agents. Afterwards, GO is obtained by exfoliating of the graphite oxide. However, the original Hummer Method has many disadvantages due to the emission of harmful, dangerous gases and its low efficiency. Many Hummer's methods have been derived by researchers from past to present. As a result of various modifications, the Modified Hummer's Method, which includes efficient, non-toxic and harmless production method steps, was preferred in GO production. Each stage of production process affects the properties and structures of the obtained GO. Understanding the effect of GO production parameters on GO structure, is important for its use in electronics, optics, biological, and graphene production applications. In Hummer's Method, after the oxidation of graphite, washing with HCl followed by distilled water is applied to remove impurities. The final step, which is the washing process, is an important step for the final structure properties of GO. In this study, the effect of pH value on the obtained GO structure was investigated by using the Modified Hummer's Method that we developed. Structural characterization studies of GO samples from solutions at different pH levels were performed using X-Ray Diffractometry (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Ultraviolet - Visible Spectrophotometer (UV-Vis). According to the obtained results, it was determined that the difference in pH level of solution changed the structure of GO and affected the degree of exfoliation. Keywords: Graphene oxide, pH, Purification, Modified Hummer’s, XRD, FTIR.

A Theological Appraisal of the Recapitulation and Ransom Theories of Atonement
Authors: Boaheng Isaac
Published: April 2022

The patristic era represents the formative period of Christian theology. As such, this period witnessed remarkable theological immaturity and complexity. One theological issue that attracted much attention in this period was atonement. Patristic scholars, in an attempt to build on the apostolic tradition, expressed varied interpretations of Christ’s death on the cross. Among the different patristic interpretations, Iranaeus’ recapitulation and Origen’s ransom theories of atonement became the most outstanding. The recapitulation theory emphasizes the restoration of the human race to their divine-given status. The ransom theory, on the other hand, stresses the transactional dimension of the atonement which resulted in the defeat of Satan. This paper critically examines these two theories using data gathered from books, journal articles, and dissertations, among other sources. The paper concluded that, though the recapitulation and ransom interpretations of the atonement are ancient theories, they are still relevant to the overall contemporary understanding of Christian soteriology. The findings from the paper will not only contribute to modern soteriological discourses but will also help readers to avoid some pitfalls that characterize the two interpretations discussed.

Uncertainty in Grain Size Estimations of Volatiles on Trans-Neptunian Objects and Kuiper Belt Objects
Authors: Emran A. , Chevrier V. F.
Published: April 2022

We analyze the uncertainty in grain size estimation of pure methane (CH4) and nitrogen saturated with methane (N2:CH4) ices, the most abundant volatile materials on trans-Neptunian objects (TNOs) and Kuiper Belt objects (KBOs). We compare the single scattering albedo, which determines the grain size estimation of outer solar system regolith, of these ices using the Mie scattering model and two other Hapke approximations (Hapke 1993) in radiative transfer scattering models (RTMs) at near-infrared (NIR) wavelengths (1–5 μm). The equivalent slab (Hapke slab) approximation model predicts results much closer to Mie scattering over the NIR wavelengths at a wide range of grain sizes. In contrast, even though the internal scattering model predicts an approximate particle diameter close to the Mie model for particles with a 10 μm radii, it exhibits higher discrepancies in the predicted estimation for larger grain sizes (e.g., 100 and 1000 μm radii). Owing to the Rayleigh effect on single-scattering properties, neither Hapke approximate models could predict an accurate grain size estimation for the small particles (radii ≤5 μm). We recommend that future studies should favor the Hapke slab approximation when employing RTMs for estimating grain sizes of the vast number of TNOs and KBOs in the outer solar system.

Authors: Ridha Nadirah Rasyid , Daud Dasril
Published: April 2022

Introduction The prevalence of cancer in children is increasing. The morphological diagnosis of acute leukemia is divided into ALL and AML and is sometimes incompatible with the diagnosis of flow cytometry, which shows the characteristics of malignant cells. This study aims to compare the results of the interpretation of bone marrow aspiration with immunophenotyping in diagnosing childhood leukemia. 
Methods Data from medical records was used in a retrospective cohort study of children with leukemia (ages 1–18 years) admitted to Dr. Wahidin Sudirohusodo Hospital Makassar from 2013 to 2017. All patients with a working diagnosis of leukemia were examined for bone marrow aspiration, followed by immunophenotyping, and each group was analyzed.
Results Of a total of 90 study subjects, the final diagnosis based on immunophenotyping was 60 ALL and 30 AML patients with a mean age of 8 years and 3 months. The male to female ratio was 1.7:1 (p = 0.353). The mean age of the ALL group was 7 years and 10 months, and AML, 9 years (p = 0.409). The suitability of morphology and flow cytometry to ALL and AML was 92.3% and 50%, respectively. Most markers were in the ALL CD 10 and CD 20 groups with a sensitivity of 100% each, and AML CD 117 with a sensitivity of 92%.
Conclusion The correspondence between the results of the interpretation of bone marrow aspiration with immunophenotyping in diagnosing ALL 92.3% and AML 50%.

Authors: Loukanov Alexandre , Kuribara Ayano , Filipov Chavdar , Nikolova Svetla
Published: April 2022

Multifunctional programmed nanomachines with theranostic functions demonstrated great potential in the clinical practice of oncology, as well as the personalized nanomedicine. The reason is because such nanoagents with combined diagnostic and therapeutic functions were found to be highly effective for cancer treatment. The appropriate design of nanomachines allows them to overcome the biological barriers of proliferative tumors and to distinguish the cancer cells from their normal counterparts. Moreover, the use of biocompatible and biodegradable precursors for construction of nanomachines minimize significantly the caused adverse effects to the normal tissue cells, which is a main problem of the chemotherapy. In addition, the utilization of theranostic nanomachines also enables an improved selectivity to the cancer in respect to its intrinsic complexity, heterogeneity, and dynamic evolution. Here we present the programmable functions and performance of the microenvironment-responsive nanomachines at a molecular level for cancer imaging and therapy.
An Experimental Investigation of ‘Drill-and-Practice’ Mobile Apps and Young Children
Authors: Herodotou Christothea , Mangafa Chrysoula , Srisontisuk Pinsuda
Published: April 2022

The choice of mobile applications (apps) for learning has been heavily relied on customer and teacher reviews, designers’ descriptions, and alignment with existing learning and human-computer interaction theories. There is limited empirical evidence to advise on the educational value of mobile apps as these are used by children. Understanding the impact of mobile apps on young children’s learning is timely given the lack of evidence-based recommendations that could guide parents and teachers in selecting apps for their children. In this paper, we present the results of a series of randomised control trial (RCTs) with 376 children aged 5 to 6 years old who interacted with two maths apps in three schools in the UK. Pre/post-test comparisons revealed learning gains in both the control and intervention groups, suggesting that the selected applications are equally good to standard maths practice. Implications for the selection and use of mobile apps are discussed.

Published: April 2022

The stroke is an important health burden around the world that occurs due to the block of blood supply to the brain. The interruption of blood supply depends on either the sudden blood supply interruption to the brain or a blood vessel leak in tissues. It is tricky to treat stroke-affected patients because the accurate time of stroke is unknown. Internet of things (IoT) is an active field and plays a major role in stroke prediction. Many machines learning (ML) techniques have been used to automate the process and enable many machines to detect the prediction rate of stroke and analyze the risk factor. The ML-based wearable device plays a significant role in making real-time decisions that benefit stroke patients. The parameters such as risk factors associated with stroke and wearable sensors and machine learning techniques for stroke prediction are discussed.

In the United States, in higher education, gaps in retention and graduation rates for students from historically marginalized communities remain at the forefront of college and university diversity, equity, and inclusion (DEI) efforts. This chapter proposes that DEI efforts must go beyond the implementation of a new initiative, program, or service to address the racial and social inequities that manifest as lagging academic outcomes. The author suggests that educators have the power to create environments that result in more equitable outcomes and the potential to advance social and racial justice with each interaction they have with students. By engaging empathy, educators can listen more closely to students' stories, understand those stories more keenly, challenge their explicit and implicit bias, and choose to incorporate new insight into their daily practice. Moreover, when educators consider the whole student experience with greater awareness and care, they help shape policies and procedures that serve students more equitably.

Social justice issues continue to impact higher education institutions with students reporting a decline in experiences that cultivate empathy. We must examine social justice work as we prepare students to navigate major academic milestones while emphasizing the promotion of cross-cultural communication. One way to foster equity is through intercultural listening, which can provide a unique opportunity to increase intercultural awareness by engaging in the practice of empathy. Educators must interrogate how to deepen our commitment to supporting historically minoritized students and evaluate how we show up to deeply value their diverse perspectives. The authors (1) introduce the concepts of intercultural listening as a practice for educators to reconsider how to build relationships with diverse students across sociocultural boundaries, (2) discuss traditional conceptualizations of empathy as the cornerstone of the field of intercultural learning, (3) present a conceptual framework for developing critical empathy, and (4) discuss application to the field of higher education.
Treatment of Water Hyacinth Fibers to Improve Mechanical and Microstructural Properties of Green Composite Materials

In this study, the water hyacinth was used as a reinforcement of green composites. The chemicals for treatment of water hyacinth were solutions of alkaline, soap and water to determine water absorption. The chemical treated process of the water hyacinth fibers had important influences to the chemical structures and mechanical properties of the green composites. Micrographs analyses of scanning electron microscope (SEM) showed obviously roughness of fiber surface after the chemical treatment as well as arrangement of structures among the water hyacinth fibers. Similarly, the results of analysis by Fourier transform infrared spectroscopy (FT-IR) showed that most of the intensity of the absorbed peaks was decreased markedly at the wavenumbers of 1375 cm-1 and 1542 cm-1. These are related to lignin extraction with alkaline solution, effectively. In particular, the compressive strength of the water hyacinth/roving composite has high value approximately to that of fiberglass composites (unfriendly composites). The water hyacinth/roving composites have significantly improvements in flexural and compressive strengths and this proves that the environmentally friendly composite responded to high requirements for various applications.
An investigation of demographic and component Allee effects in the Madagascar hissing cockroach

Population density affects the behaviour and population dynamics of insects, but the nature of that effect may depend on the degree of sociality. We experimentally manipulated initial population density of a subsocial insect, the Madagascar hissing cockroach,Gromphadorhina portentosaSchaum, 1853 (Blattodea: Blaberidae), to determine its effect on vital rates and population dynamics. In accordance with the predicted Allee effect, we hypothesised that intermediate cockroach population density will increase per capita birth rates and cause a higher population growth rate relative to smaller and larger population densities. After tracking 12 experimental populations (three replicates of four initial population densities) for 15 months, we found evidence of Allee effects in this insect. Per capita birth rates showed a quadratic response, with rates highest at intermediate population densities, suggesting a component Allee effect. Contrary to expectations for a demographic Allee effect, population growth rates showed negative density dependence. The proportion of adult females in the population increased with population density, but the mechanism for this increase is not known. Our findings provide evidence for at least one form of Allee effect inG. portentosaand shows a possible connection between subsocial behaviour and population-level responses.
Oxygen therapy using Bain’s Circuit as an alternate option for moderate COVID-19 patients in resource-limited set-ups

Dear Editor,

Coronavirus disease of 2019 (COVID- 19) has been slowly engulfing society since December 2019. Many parts of the world are facing the second and third waves of the pandemic. The virus is rapidly getting mutated, posing a significant challenge. Oxygen therapy is required in most symptomatic patients, and most mild-to-moderate cases are managed by supportive therapy using a face mask. Non-Rebreathing Facemask (NRBM) is frequently used as it can provide a higher fraction of inspired Oxygen (FiO2). However, it cannot deliver a Positive End- Expiratory Pressure (PEEP). Even the positive pressure generated inside the mask is nearly zero.

Bioetica clinica. Intervento cardiochirurgico in tossicodipendente con endocardite
Authors: Manna Raffaele , Cascio Marietta , Spagnolo Antonio G.
Published: April 2022

Gli autori presentano il caso clinico di un uomo di 37 anni con una storia di tossicodipendenza intravenosa che viene ricoverato in un ospedale con diagnosi di endocardite batterica, e per il quale si profila la necessità di un intervento cardiochirurgico di sostituzione valvolare. L'équipe cardiochirurgica chiamata per la consulenza si mostra perplessa ad intervenire in quanto l'intervento si presenta effettivamente rischioso, le possibilità di recidiva sono elevate, ma soprattutto il paziente è indigente e non ha possibilità di sostenere le spese elevate che l'intervento e le cure postoperatorie comportano. L'esame dci dati clinici e dei valori etici in gioco fanno concludere agli autori che esiste qui una ben precisa indicazione terapeutica all'intervento cardiochirurgico, unica possibilità di salvezza per il paziente, e che il processo decisionale medico non può essere influenzato dalle condizioni economiche del paziente. Gli autori esaminano, infine, le differenti posizioni che emergono nella letteratura sul tema dell'etica ed economia sanitaria.
Secondary School Athletic Coaches' Perceptions and Knowledge of the Athletic Training Profession

Published: April 2022

Context

Coaches play a role in streamlining care, especially by directing student-athletes in need of further medical attention to the athletic trainer (AT). The AT-coach relationship holds great potential for incorporating collaborative care, and yet, little is known about coaches' perceptions and knowledge of ATs.

Objective

To investigate coaches' perceptions of athletic training and their knowledge regarding the roles and responsibilities of ATs in secondary schools.

Design

Concurrent mixed-methods study.

Setting

Cross-sectional online questionnaire.

Patients or Other Participants

Secondary school athletic coaches from 10 sports with the highest participation rates during the 2017–2018 season (n = 1097). Most respondents were male (n = 795, 72.4%), and their average age was 44.7 ± 11.4 years.

Main Outcome Measure(s)

Participants completed a web-based questionnaire containing demographics and quantitative measures assessing their perceived value and knowledge of ATs, as well as open-ended questions. Descriptive statistics summarized the demographic data. Counts and percentage responses for quantitative measures were reported. Open-ended responses were analyzed using the general inductive approach.

Results

Approximately 93% of respondents considered an AT a trusted source of medical information and a key member of the sports medicine team. Most respondents selected injury prevention (98.9%), first aid and wound care (97%), therapeutic interventions (89.9%), and emergency care (85.8%) as skills ATs are qualified to perform. Forty-six percent of respondents were willing to coach without an AT employed. Coaches trusted ATs as part of the “athletic team” and as gatekeepers, referring student-athletes for advanced care when warranted. Regarding the AT role, coaches emphasized the treatment of minor injuries and the idea of “coverage versus care.”

Conclusions

Secondary school coaches valued the athletic training profession and were knowledgeable regarding various roles and responsibilities ATs frequently perform. However, they may view ATs as luxuries instead of necessities, as evidenced by the fact that just under half of responding coaches were willing to coach without an AT employed at the school.
