Chemically Catalyzed Phytoextraction for Sustainable Cleanup of Soil Lead Contamination in a Community Garden in Jersey City, New Jersey
Authors: Zhang Zhiming , Sarkar Dibyendu , Levy Frances , Datta Rupali
Published: May 2023

Soil lead (Pb) contamination in Pb paint-contaminated homes is a serious health risk in urban areas. Phytoextraction is a green and sustainable technology for soil Pb remediation, but its efficiency depends on the geochemical partitioning of Pb in soil. Following successful laboratory, greenhouse, and panel experiments, a field study was conducted to demonstrate the effectiveness of a chemically catalyzed phytoextraction model for Pb removal. A biodegradable chelating agent, ethylenediaminedisuccinic acid (EDDS) was applied during Pb phytoextraction by vetiver grass (Chrysopogon zizanioides) in a Pb-contaminated community garden in Jersey City, New Jersey. Results showed that soil Pb concentration was reduced from 1144 to 359 mg/kg in 3 years, despite ongoing Pb input to the field plots from a nearby construction site. EDDS was effective in converting non-plant-available forms of Pb (i.e., carbonate-bound, oxide-bound, and organic-bound forms) to plant-available forms (i.e., water-soluble and exchangeable forms). With EDDS application, vetiver roots accumulated 532, 231, and 401 mg/kg of Pb in Years 1, 2, and 3, respectively, which were higher than the values obtained without EDDS applications (228, 154, and 214 mg/kg). This field study demonstrated the effectiveness of a chemically catalyzed phytoextraction model for Pb removal from urban soils.

Published: May 2023

Mosquitoes are competent vectors for many important arthropod-borne viruses (arboviruses). In addition to arboviruses, insect-specific viruses (ISV) have also been discovered in mosquitoes. ISVs are viruses that replicate in insect hosts but are unable to infect and replicate in vertebrates. They have been shown to interfere with arbovirus replication in some cases. Despite the increase in studies on ISV–arbovirus interactions, ISV interactions with their hosts and how they are maintained in nature are still not well understood. In the present study, we investigated the infection and dissemination of the Agua Salud alphavirus (ASALV) in the important mosquito vector Aedes aegypti through different infection routes (per oral infection, intrathoracic injection) and its transmission. We show here that ASALV infects the female Ae. aegypti and replicates when mosquitoes are infected intrathoracically or orally. ASALV disseminated to different tissues, including the midgut, salivary glands and ovaries. However, we observed a higher virus load in the brain than in the salivary glands and carcasses, suggesting a tropism towards brain tissues. Our results show that ASALV is transmitted horizontally during adult and larval stages, although we did not observe vertical transmission. Understanding ISV infection and dissemination dynamics in Ae. aegypti and their transmission routes could help the use of ISVs as an arbovirus control strategy in the future.

Published: May 2023

Important for irrigation, the transboundary river basin between Kyrgyzstan and Kazakhstan is vulnerable to geochemical and anthropogenic sources of pollution. The use of water use indices, together with measurements of the elemental and radionuclide composition of the water and bottom sediments, provides a means for evaluating the continued use of the water from this region. Recent monitoring shows the highest concentrations of hazardous contaminants include lead and thorium contained in the bottom and banks of the Kichi-Kemin River. These contaminants are likely remnants of an accidental spill at the Aktyuz tailing dump in 1964. The specific activity of the Th-232 of the bottom and banks of the Kichi-Kemin River is 107–189 Bq/kg. There is evidence of anthropogenic sources of additional pollution from uranium in both the bottom sediments and the water in the Oyrandy River. The geochemical origins of uranium and other associated elements in the water of the Shu River are likely the Kamyshanovskoye deposit. Contact between the riverbed and ore bodies in this region likely leads to elevated concentrations of several geogenic contaminants, including lithium, strontium, uranium, and boron (Li, Sr, U, B), increasing by as much as 60–130%. The uranium concentrations in the water of channels that are used for irrigation exceed the maximum allowable contaminant levels by 3.8 times. Future work is needed to evaluate the ecological and human health impacts of these contaminants in irrigation and drinking water.
A Spatiotemporal Deep Learning Approach for Urban Pluvial Flood Forecasting with Multi-Source Data
Authors: Burrichter Benjamin , Hofmann Julian , Koltermann da Silva Juliana , Niemann Andre , Quirmbach Markus
Published: May 2023

This study presents a deep-learning-based forecast model for spatial and temporal prediction of pluvial flooding. The developed model can produce the flooding situation for the upcoming time steps as a sequence of flooding maps. Thus, a dynamic overview of the forthcoming flooding situation is generated to support the decision of crisis management actors. The influence of different input data, data formats, and model setups on the prediction results was investigated. Data from multiple sources were considered as follows: precipitation information, spatial information, and an overflow forecast. In addition, models with different layers and network architectures such as convolutional layers, graph convolutional layers, or generative adversarial networks (GANs) were considered and evaluated. The data required to train and test the models were generated using a coupled hydrodynamic 1D/2D model. The model setup with the inclusion of all available input variables and an architecture with graph convolutional layers presented, in general, the best results in terms of root mean square error (RMSE) and critical success index (CSI). The prediction results of the final model showed a high agreement with the simulation results of the hydrodynamic model, with drastic reductions in computation time, making this model suitable for integration into an early warning system for pluvial flooding.

Authors: García-Mora Victor Mario , Ilbay- Yupa Mercy , Ramos Veintimilla Raúl Armando
Published: May 2023

En este estudio se generó el modelo de regresión múltiple para predecir el rendimiento del cultivo de papa (Solanum tuberosum) en Ecuador, utilizando el registro anual de la producción de las Encuestas de Superficie y Producción Agropecuaria para el periodo 2002-2019. Las variables independientes consideradas, fueron la superficie sembrada con semillas comunes, mejoradas y certificadas, prácticas de cultivo, volumen de venta y superficie sembrada, perdida y cosechada.  Los resultados evidencian que el rendimiento se ve influenciado por cinco variables independientes como son:  semilla mejorada, riego, aplicación de fertilizantes, helada y otros. El modelo de regresión múltiple presenta un buen ajuste con un coeficiente de determinación de 0,86, un RMSE de 1,014 ton/ha y un MAE significativamente bajo (0,024 ton/ha), el cual ayuda a verificar el arreglo del modelo. Por otra parte, la evaluación del incremento del rendimiento (p≤0.01) reveló tasas de crecimiento promedio anual entre 0,87 y 2,07% para las provincias de Tungurahua (0,87%), Pichincha (1,26%), Chimborazo (1,54%), Carchi (1,71%), Cotopaxi (1,91%) y Bolívar (2,07%). La predicción del rendimiento del cultivo de papa en Ecuador se centra principalmente en la influencia de los factores climáticos y tecnologías de cultivo. Es importante que las acciones políticas permitan que los agricultores tengan acceso al crédito y favorezca el uso de tecnologías de manejos del cultivo como el riego, fertilización y controles fitosanitarios.

Consider the identric mean \(\mathcal{I}\), the logarithmic mean \(\mathcal{L,}\) two trigonometric means defined by H. J. Seiffert and denoted by \(\mathcal{P}\) and \(\mathcal{T,}\) and the hyperbolic mean \(\mathcal{M}\) defined by E. Neuman and J. Sándor.

Authors: Diaconu Adrian
Published: May 2023

This paper completes the results that are presented in [14]. Using as a starting point the abstract method of the chord, in the mentioned paper we have presented an iterative method of approximation for the solutions of an equation. This method uses auxiliary sequences, and aims to improve the convergence order. The used method generalizes the method of Aitken-Steffensen. In the paper [14] we have given the statement of the main theorem and the statement and the proof of an auxiliary proposition concerning the convergence of some recurrence sequences of real numbers. In the present paper we give the proof of the main result and at the same time we discuss an interesting special case.

EFFICIENCY AND PROBLEMS OF ONLINE LEARNING FOR SECONDARY SCHOOL STUDENTS
Authors: Исламгереева Я.С.
Published: May 2023

Пандемия COVID-19 вынудила к немедленному внедрению онлайн-обучения. Однако мало что известно о его эффективности и проблемах, с которыми сталкиваются студенты. Таким образом, данное исследование направлено на изучение эффективности онлайн-обучения и проблем, которые оно создает для способностей учащихся к обучению. В этом исследовании использовался дизайн тематического исследования с использованием вопросника опроса, проведенного среди 99 учащихся средней школы в Ясине, Малака. Данные были проанализированы описательно (расчет процента и частоты). Как правило, результаты показали, что у студентов есть компьютеры или смартфоны и подключение к Интернету дома. Кроме того, было обнаружено, что способность и удобство использования компьютеров были высокими (> 93%). Однако их мотивация к онлайн-обучению была низкой (41,5%), а способность работать в группе была на умеренном уровне (66,7%). Они также согласились с тем, что традиционное обучение (очное) важно для их обучения (98%). Эти результаты ценны для правительства, школьной администрации, учителей и родителей, чтобы признать важность хорошо оборудованных помещений и стабильного подключения к Интернету для эффективного обучения. Тем не менее, будущим исследователям рекомендуется использовать больший размер выборки и студентов из разных слоев общества, чтобы лучше понять этот вопрос [1].

The COVID-19 pandemic forced the immediate introduction of online learning. However, little is known about its effectiveness and the problems faced by students. Thus, this study is aimed at studying the effectiveness of online learning and the problems that it creates for students' learning abilities. This study used a case study design using a survey questionnaire conducted among 99 secondary school students in Yasin, Malaka. The data were analyzed descriptively (percentage and frequency calculation). As a rule, the results showed that students have computers or smartphones and an Internet connection at home. In addition, it was found that the ability and usability of computers were high (> 93%). However, their motivation for online learning was low (41.5%), and their ability to work in a group was at a moderate level (66.7%). They also agreed that traditional (full-time) education is important for their education (98%). These results are valuable for the government, school administration, teachers and parents to recognize the importance of well- equipped facilities and a stable Internet connection for effective learning. However, future researchers are encouraged to use a larger sample size and students from different backgrounds to better understand this question.

Este trabajo tiene como objetivo identificar los beneficiarios de los subsidios a la oferta del servicio de transporte colectivo del área metropolitana de Mendoza; a través de una metodología que integra técnicas econométricas con técnicas cartográficas. Los subsidios aplicados a este servicio son instrumentos económicos que buscan expandir el mercado del mismo, lo cual es deseable desde la búsqueda de sistemas de movilidad más sostenibles y que promuevan territorios accesibles. La hipótesis que guía el trabajo es que dichos beneficiarios no pertenecen al grupo de población que más necesita del servicio, particularmente la franja de población de menor poder adquisitivo. Los resultados obtenidos avalan dicha hipótesis, evidenciando la necesidad de una redistribución de las asignaciones con algún criterio espacial.

Active learning in the undergraduate laboratory: giving students a safe space to experience low-stakes failure
Authors: Edmunds Kelly , Leggett Helen Catherine
Published: May 2023

As with COVID-19, and so with national and global economic, political and climate crises, it is our young people who are the most vulnerable. In the UK, young people are experiencing a mental health crisis, and schools and universities are reporting record low levels of engagement amongst their students. What can educators do to support the healthy development of young people in education today? Here we present a case study from a large (179 students) Foundation Year Biological Sciences module where we considered the potential for low-stakes failure teaching events to act as a tool for developing student confidence and resilience, whilst also providing an active learning experience. We offered Foundation Year university students the opportunity to engage in a low-stakes failure laboratory practical session, where the students designed and completed simple microbiology experiments in small groups. This was then followed by the opportunity to repeat the experiment three months later, as well as additional interactive workshops for the students to analyse the data from the practical experiment and reflect on their learning experience. We found that students took a variety of approaches to the practical experiment with the majority describing the experiment as a positive experience. Students reported developing subject-specific skills including aseptic techniques, pipetting, plating bacteria, experimental design, in addition to transferable and “soft” skills such as teamwork, problem solving, and building confidence to try something new (experiment!). Ninety-two percent of student respondents felt that the experience offered a safe space for them to experiment with scientific techniques. We discuss considerations for further research as well as the potential for embedding low-stakes failure within a programme of study at Higher Education.

Crusader Papal - Spanish Policy toward Al-Andalus after fall of Constantinople (1453-1492 A. D.\857-897 A. H.)
Authors: Al-Qobbaj Amer
Published: May 2023

The fall of Constantinople by the Ottomans in 1453 A. D., led to the collapse of Byzantine Empire, which was considered one of the most powerful empires throughout history, after it had ruled vast parts of the Near East and Middle European countries for more than eleven centuries. Its collapse paved the way before Muslims to enter and possess large areas of lands and properties of the Christian Eastern Europe, and enabled the Ottomans to reach the heart of Europe, which made the entire Western Europe under the Islamic threat. The papacy was of the most European parties aware of that imminent danger, so it well prepared to confront the Islamic threat through forming anti-military religious Christian western alliance in parallel with recruiting all the papacy and European forces to support the Christian kingdoms in Spain financially, humanly, religiously and morally, so as to eliminate the Islamic presence in Al-Andalus homeland, subsequently to compensate the losses incurred by the Christians in the East, and this was achieved in 1492 A. D., when the Spaniards, with the help of the papacy, ended the rule of Granada, the last islamic kingdom in Al-Andalus.

أدى سقوط مدينة القسطنطينية بيد العثمانيين سنة 1453م/857هـ إلى انهيار الإمبراطورية البيزنطية التي تُعدّ من أقوى الإمبراطوريات التي نشأت عبر التاريخ؛ بعد أن حكمت أجزاء واسعة من بلاد الشرق الأدنى والشرق الأوروبي لما يزيد عن أحد عشر قرناً، فمهّد سقوطها لدخول مناطق ومساحات كبيرة من أراضي الشرق الأوروبي المسيحي في حوزة المسلمين، وإثر ذلك تمكّن العثمانيون من النفاذ إلى قلب أوروبا، مما جعل الغرب المسيحي برمته في دائرة التهديد والخطر الإسلامي. واستشعرت البابوية في روما خطورة نتائج سقوط القسطنطينية، كما تبددت أحلامها ومساعيها الرامية لمدّ نفوذها وسيطرتها الروحية إلى مختلف أرجاء العالم المسيحي، فبدأت تعدّ العدة لمواجهة الزحف العثماني؛ من خلال إيجاد حلف عسكري ديني مسيحي غربي مضاد، ولمّا فشلت في ذلك، وجدت ضالتها في الممالك المسيحية الإسبانية التي كانت حينذاك تواصل سياسة إعادة الاسترداد الصليبية؛ بهدف القضاء على الوجود الإسلامي في الأندلس، فسخّرت البابوية جلَّ إمكاناتها لدعم الإسبان مادياً وبشرياً ودينياً ومعنوياً؛ من أجل الانتصار على الأندلسيين في الغرب، في محاولة لتعويض الخسارة التي تكبّدها العالم المسيحي على أيدي العثمانيين في الشرق، وهو ما تم إنجازه سنة 897هـ/1492م، عندما أجهز الإسبان المدعومون بابوياً على مملكة غرناطة؛ آخر الممالك الإسلامية في بلاد الأندلس.
Critical Amplitude of Acoustical Attenuation in Mode-Coupling Theory for the Binary Mixture Aniline and Cyclohexane
Authors: Abdelraziq Issam
Published: May 2023

Using Hornowski’s theoretical modification of the critical amplitude, the experimental ??(crit)/?u(?)2A(T) values from mode-coupling theory of a binary liquid mixture aniline – cyclohexane have been compared with the theoretical expressions given by Fixman, Kawasaki, Mistura, and Chaban. The experimental data at low reduced frequencies ?* has been found to agree well with the Hornowski’s model of A(T). However, for the large values of reduced frequency ?* > 10 the mode-coupling theory of Shiwa and Kawasaki still exhibits poor agreement with the observed data, mainly due to the form of scaling function. The correlation length ?0 has been calculated by using ?0 ( the critical amplitude of the characteristic relaxation rate ) which gives the best fitting to the theoretical critical amplitude. The adiabatic coupling constant g and the diffusion coefficient D0 have been obtained using Hornowski’s expression of the critical amplitude.
Concentration and Temperature Dependence of Shear Viscosity of the Critical Mixture of Nitroethane and 3-Methylpentane
Authors: Abdelraziq Issam
Published: May 2023

Shear viscosity coefficients of nitroethane and 3-methylpentane mixture have been measured using digital viscometer. The measured values were over the entire concentration range above the critical temperature (Tc = 299.590 K) in the range 0.040 ? T- Tc ? 18.570 K. The results above the critical temperature Tc were analyzed by the mode coupling theory. The anomaly of shear viscosity was detected as a function of temperature and concentration. A least square fit near the critical temperature yields a value of noncritical part of shear viscosity ?0 = 0.358 cP. The Debye momentum cutoff qD and the constant A in the mode coupling approach were determined. Our values of ?0 and A are in good agreement with the literature values.

INTRODUÇÃO: A avaliação do potencial de jovens atletas é uma importante tarefa dos treinadores. A tentativa de quantificar o “olho do treinador” tem sido um grande desafio para os pesquisadores. OBJETIVO: Comparar indicadores multidimensionais do talento esportivo em jovens handebolistas classificados como alto e baixo potencial esportivo, de acordo com a opinião do treinador. MÉTODOS: Participaram 22 atletas de handebol de 15 a 17 anos de um Instituto Federal de Ensino. O potencial esportivo foi avaliado pelo treinador da equipe, numa escala de um a cinco, classificando os atletas em dois grupos: alto potencial (n=11) e baixo potencial (n=11). Foram avaliados: experiência esportiva, massa corporal, estatura, altura sentado, comprimento de mãos, envergadura, dobras cutâneas, velocidade, agilidade, preensão manual, salto vertical, flexibilidade, resistência aeróbica; habilidades de coping, motivação, competência percebida, nível socioeconômico, maturação biológica, drible e habilidades táticas. RESULTADOS: Os handebolistas de alto potencial quando comparados aos de baixo potencial foram mais velozes (p=0,05), mais ágeis (p=0,02) e mais fortes (p=0,02), eram mais experientes (p=0,05), apresentaram maior competência percebida (p=0,01), competitividade (p=0,02) e melhor desempenho no drible (p=0,05) e nas habilidades táticas (p=0,03). CONCLUSÃO: Os handebolistas avaliados pelo treinador como alto potencial esportivo foram aqueles que tiveram melhor desempenho físico-motor, maior nível de habilidades psicológicas, técnicas e táticas quando comparados aos atletas de baixo potencial.
