Published: January 2023

In this study, three different reusable photocatalysts containing different amino acids as a source of non-metals, including L-Arginine, L-Proline, and L-Methionine, have been synthesized for the first time. Using a kinetic study and degradation efficiency test, these visible driven photocatalysts were investigated for their photocatalytic activity in removing antibiotics, including metronidazole (MNZ) and cephalexin (CEX). The morphology, structure and optical properties of the fabricated catalysts were characterized by X-ray Powder Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive Spectrometry (EDS)/mapping, Fourier-Transform Infrared Spectroscopy (FTIR), Photoluminescence Spectroscopy (PL) and UV-Vis Diffuse Reflectance Spectroscopy (DRS) analyses. Based on the results of the PL analysis, it was confirmed that doping TiO2 with amino acids containing C, N, and S inhibited the recombination of induced electrons and holes. Among the three catalysts, L-Arginine-TiO2 demonstrated the highest photocatalytic activity for antibiotic degradation, followed by L-Proline-TiO2. According to the response surface methodology (RSM), the optimum operating conditions were a concentration of 50 mg/L MNZ, pH = 4, and catalyst concentration = 1.5 g/L under 90 min of irradiation time. At this condition, 99.9% of MNZ and 81% of TOC were removed. In addition, 97.2% of CEX and 75% TOC were eliminated at the optimum conditions of 1g/L catalyst concentration, 50 mg/L CEX concentration, at neutral pH, and after 120 min irradiation. L-Arginine (1 wt.%)-TiO2 was tested for stability and reusability, and it showed that after five cycles, 10% of its performance had been lost. The role of reactive species in photocatalysis was identified and •OH had the most significant impacts on MNZ and CEX photodegradation. Antibiotic degradation efficiency was adversely affected by the presence of anions and humic acid, but this reduction was not significant for inorganic anions, as only 13% of degradation was lost.

Published: January 2023

Microalgae play an important role in the formation of biofloc. To demonstrate the feasibility of Chlorella pyrenoidosa in biofloc formation, an experiment was performed with a simple random design consisting of five inoculation levels (in triplicate) of C. pyrenoidosa (0, 1 × 108, 1 × 109, 5 × 109, and 1 × 1010 cells·L−1) in the biofloc system. All treatments kept a C:N ratio of approximately 15:1. This study observed the effects of different initial concentrations of C. pyrenoidosa on biofloc formation, water quality and bacterial community in biofloc systems. The results indicated that C. pyrenoidosa had the ability to enhance biofloc development, especially when the C. pyrenoidosa initial concentration reached 5~10 × 109 cells·L−1. Too high or too low a concentration of C. pyrenoidosa will adversely affect the formation of biofloc. The effect of C. pyrenoidosa addition on water quality (TAN, NO2−-N, and NO3−-N) was not significant in the final stage. The inoculation of C. pyrenoidosa decreased the species richness and diversity of the bacterial community but increased the domination of Proteobacteria and Bacteroidota in the biofloc system, especially the order of Rhizobiales. The addition of C. pyrenoidosa could maintain water quality by increasing the proportion of several denitrifying bacteria, including Flavobacterium, Chryseobacterium, Pseudomonas, Brevundimonas, Xanthobacter, etc. These above dominant denitrifying bacteria in the biofloc system could play a major role in reducing the concentration of NO2−-N and NO3−-N. So, we recommended the reasonable concentration is 5~10 × 109 cells·L−1 if C. pyrenoidosa is used to rapidly produce biofloc.

Authors: Liu Jiaju , Guo Huaicheng
Published: January 2023

In order to investigate the hydrochemical characteristics and their controlling factors, 212 water samples from the Yarlung Tsangpo River and its tributaries were collected over three precipitation periods in 2018 and analyzed using mathematical statistics, the Gibbs and ion ratio methods, and principal component analysis. The results showed the following: (1) The cations in the water were mainly Ca2+, Na+ and Mg2+, and the anions HCO3− and SO42− were predominant, accounting for more than 97% of the total anion concentrations. The concentration of total dissolved solids (TDS) was 204.51 mg/L. The water chemistry type was SO4·(HCO3)−Ca·(Mg) water. (2) The concentrations of major ions in the Yarlung Tsangpo River fluctuate, but in general, the vast majority of the major ions in the water follow the trend of both first increasing and then decreasing in the three precipitation periods. The hydrochemical features of the Yarlung Tsangpo Basin have seasonal differences. (3) The Gibbs model and the PCA analyses showed that the Yarlung Tsangpo River water chemical components are mainly affected by rock weathering. In addition, the influence of the mining industry also plays an important role. The heavy metal concentrations in the three precipitation periods of the Yarlung Tsangpo River could reach the standard of first-class surface water quality.
Seawater Greenhouse Equipped with a Novel Solar Humidification-Dehumidification Desalination Unit in MAKRAN Coast: Fabrication and Experimental Study
Authors: Zamen Mohammad , Kahani Mostafa , Zarei Ghasem
Published: January 2023

The purpose of this study is the fabrication and performance evaluation of a new type of solar humidification–dehumidification (HD) desalination unit to supply sufficient fresh water for a seawater greenhouse in the MAKRAN coast in southeast Iran. In the proposed design, a particular type of air-to-air condenser is used. The cold air coming out of the greenhouse ventilation system (fan and pad) in summer and the cold ambient air in winter is used to supply the required cooling of the system. In this way, when cold air passes over the pipes in air-to-air condensers, condensation of water vapor occurs in the moist air inside the pipes, and fresh water is produced. Greenhouse fans, which have an air flow rate of around 20,000 m3/hr, are used to create this air flow. By fabricating two condensers, each using 42 rows of PVC pipes with a diameter of 75 mm, it is possible to produce 400 L of fresh water per day in a 400 m2 greenhouse. The required heating is provided by the solar farm, which includes 96 square meters of flat plate collectors. The steps of unit fabrication are described in detail in this research. However, the effect of greenhouse air temperature and circulating seawater flow rate on freshwater production, energy consumption, and energy intensity are also investigated. By increasing the flow rate of circulating seawater and decreasing the greenhouse air temperature, the production rate of the system increases. When the hot seawater and greenhouse air temperature are 61.7 °C and 26 °C, respectively, the maximum instantaneous production is estimated to be 80 L/h. The energy intensity of the HD desalination unit is varied between 3192 and 4382 kJ/L, and the gain output ratio of the system is around 0.6. The proposed system can be easily paired with conventional greenhouses employing a fan and pad cooling system and produces around 1.25 (L/m2·day) fresh water.

Authors: Javaid Zeshan , Ghazala  , Ibrahim Muhammad , Mahmood Abid , Bajwa Ali Ahsan
Published: January 2023

The widespread use of pesticides leads to the contamination of groundwater, which harms environment and threatens life. The goal of the current study was to determine the degree of pesticide contamination of groundwater in agricultural regions with varying degrees of pesticide use. In 15 districts of the Punjab province of Pakistan, chemical residues of major pesticide groups including, neonicotinoids, organophosphates, carbamates and pyrethroids were detected in the water samples. Two most commonly used herbicides, isoproturan and diuron, were also tested but not detected in any of the water samples. Five districts in the southern Punjab/core area had highly contaminated groundwater due to the presence of residues from all major insecticide groups. Although less severe than in the core area, a different set of five districts in central Punjab also had significant water contamination issues. The districts located in marginal area had the lowest amount of insecticide residues. The highest levels of imidacloprid residues were identified in the core area throughout the winter season. Thiacloprid, fipronil, and acetamiprid were detected in nearly all water samples, with non-significant differences in concentrations throughout the summer and winter seasons, as well as in non-core and marginal areas. Different water quality parameters including, pH, electrical conductivity and temperature had varying degree of correlations with pesticide residues in water samples. Overall, it is concerning that significant insecticides are widely contaminating groundwater. This issue should be managed through integrated pest management, non-chemical pest control strategies, and judicious chemical use practices.

Published: January 2023

Due to high consumption and non-renewable nature of fossil fuels, rapid development of potential renewable energies such as biofuel derived from microalgae is necessary for achieving the goals of sustainable growth and carbon neutrality. However, the high energy consumption required for microalgal biomass harvesting is regarded as a major obstacle for large-scale microalgal biofuel production. In the present study, the marine green microalgae Tetraselmis sp. was used to investigate a rapid and energy-efficient biomass collection method among different methods such as gravity sedimentation, auto-flocculation (at target pH), flocculation by polymers followed by magnetic separation, and centrifugation. The results showed that sufficient high cell densities of microalgae were obtained under the optimized growth conditions after 21 days of cultivation, and the microalgae could be easily flocculated and collected by magnetic separation using synthesized magnetic nanocomposites. The results also showed that among the different methods, magnetic separation was more efficient for biomass harvesting because of its simple and fast processing steps as well as low energy consumption. However, further investigation on different target microalgal species and their cultivation conditions, such as salinity and medium pH, will be required before application for large-scale biofuel production in the future.
Performance Evaluation of Large-Scale Green Roofs Based on Qualitative and Quantitative Runoff Modeling Using MUSICX
Authors: Nguyen Cuong Ngoc , Tariq Muhammad Atiq Ur Rehman , Browne Dale , Muttil Nitin
Published: January 2023

Green roofs (GR) are known as one of the most effective water-sensitive urban design (WSUD) strategies to deal with numerous environmental and social issues that urbanized cities face today. The overall quality of research on GRs has significantly improved and an increasing trend is observed in the amount of research over the last decade. Among several approaches, the application of modeling tools is observed to be an effective method to simulate and evaluate the performance of GRs. Given that studies on GRs at a catchment scale are limited, this paper aims to provide a simple but effective framework for estimating the catchment-scale impacts of GR on runoff quantity and quality. MUSICX, an Australian-developed software that possesses the advantages of a conceptual model, is chosen as the modeling tool in this study. While MUSICX has built-in meteorological templates for Australian regions, this tool also supports several climate input file formats for application by modelers in other parts of the world. This paper presents two different modeling approaches using the Land Use node and Bioretention node in MUSICX. The steps used for model calibration are also provided in this paper. The modeling results present the annual reductions in runoff volume, total suspended solid (TSS), total phosphate (TP), and total nitrogen (TN) load. The largest reductions of roughly 30% per year were observed in runoff volume and TN load. The annual runoff reduction rate reported in this study is close to that of other published results. Similar research outcomes quantifying the benefits of GRs play a major role in facilitating the widespread implementation of GRs due to the awareness of both positive and negative impacts of GRs. Future studies are recommended to concentrate on modeling the impacts of implementing GRs at a large scale (i.e., scales exceeding the single-building scale) to fill the research gaps and enhance the modeling accuracy.

Published: January 2023

Aiming at the problem of body instability caused by actuator failure in a distributed electric vehicle drive system, a fault-tolerant control strategy of longitudinal and lateral force cooperative reconstruction with active steering control was proposed, and a layered control structure was adopted based on the vehicle model. In the upper controller, the resultant force and torque are calculated according to the vehicle parameter state and MPC algorithm; the lower controller is the cooperative reconfiguration allocation layer, and the minimum tire load rate, longitudinal and lateral force constraints and front wheel angle control are considered. Finally, offline simulation experiments and hardware-in-the-loop experiments are completed to verify the effectiveness and real-time performance of the designed strategy. The results show that the designed strategy can significantly improve the driving stability and safety of the vehicle when the actuator fails.

Authors: Li Yaohua , Yang Zhengyan , Zhai Dengwang , He Jie , Fan Jikang
Published: January 2023

In order to solve the problem where the traditional electric power steering system (EPS) provides too much assist torque under low load and low adhesion coefficient, which damages the driver’s road feeling and affects driving safety, this paper designs a multi-map EPS control strategy. First, based on the change of steering resistance torque under different front axle loads and adhesion coefficients, EPS power characteristics considering the front axle load and adhesion coefficient were designed. In addition, the BP (Back Propagation, BP) neural network is used to determine steering resistance torque under different front axle loads and adhesion coefficients. Furthermore, the EPS control strategy based on multi-map is proposed. The proposed control strategy is evaluated through the co-simulation of Trucksim and Simulink. Simulation results show that the proposed EPS control strategy gives the vehicle good steering portability, with the handling torque meeting the ideal handling torque for a commercial vehicle. Under light load and low adhesion coefficient conditions, the lateral acceleration and yaw rate with traditional EPS are 0.1674 g and 5.641 deg/s, and with multi-map EPS are 0.1399 g and 4.715 deg/s. Therefore, the vehicle’s handliitung stability is improved. The steering wheel torque gradient is also increased, and the driver’s road feeling is improved.
Sensitivity Analysis of Electric Energy Consumption in Battery Electric Vehicles with Different Electric Motors
Authors: Mavlonov Jamshid , Ruzimov Sanjarbek , Tonoli Andrea , Amati Nicola , Mukhitdinov Akmal
Published: January 2023

In the last decade, a number of research works in electrified vehicles have been devoted to the analysis of the electric consumption of battery electric vehicles and the evaluation of the main influencing factors. The literature analysis reveals that the electric motor size, efficiency, and driving condition substantially affect the electric energy stored in the vehicle battery. This paper studies the degree of sensitivity of energy consumption to electric motor size and to its efficiency map characteristics. In order to accomplish this task, three electric motors whose parameters are re-scaled to fit the maximum power torque and speed with different efficiency maps are simulated by installing them on two commercially available battery electric vehicles. This allows for isolating the influence of the efficiency map on electricity consumption. The original characteristics of the motors are then used to evaluate the influence on the electricity consumption of both the size and the efficiency characteristics. The results of the simulation revealed that the influences of the efficiency map and the electric motor size can be around 8–10% and 2–11%, respectively. When both factors are taken into account, the overall difference in electricity consumption can be around 10–21%.

Published: January 2023

This study investigated the impact of ice formation on the performance and aerodynamics of a vertical axis wind turbine (VAWT). This is an area that is becoming more prevalent as VAWTs are installed alongside horizontal axis wind turbines (HAWTs) in high altitude areas with cold and wet climates where ice is likely to form. Computational fluid dynamics (CFD) simulations were performed on a VAWT without icing in Ansys to understand its performance before introducing ice shapes obtained through the LewInt ice accretion software and repeating simulations in Ansys. These simulations were verified by performing a wind tunnel experiment on a scale VAWT model with and without 3D printed ice shapes attached to the blades. The clean blade simulations found that wind speed had little impact on the performance, while reducing the blade scale severely reduced performance. The ice formation simulations found that increasing the icing time or liquid water content (LWC) led to increased ice thickness. Additionally, glaze ice and rime ice conditions were investigated, and it was found that rime ice conditions that occur in lower temperatures caused more ice to form. The simulations with the attached ice shapes found a maximum reduction in performance of 40%, and the experiments found that the ice shapes made the VAWT unable to produce power.

O ambiente escolar como facilitador para o desenvolvimento moral de crianças e adolescentes
Authors: Fernandes Elen Daiane Quartaroli , Ferreira Patrícia Elisabete , Martins Raul Aragão
Published: January 2023

Marcada pela diversidade de estilos culturas e valores, a escola se caracteriza como um espaço de conflitos e relações interpessoais. Saber como lidar com eles, de forma a utilizá-los como ferramenta de reflexão para uma consciência autônoma, se torna um desafio, mas pode favorecer a promoção da convivência dos educandos neste espaço.  Essa pesquisa tem por objetivo refletir sobre a importância do ambiente escolar no desenvolvimento moral de crianças e adolescentes, a partir de uma discussão teórica sobre o tema e da análise de duas experiências, bem-sucedidas, sobre como a escola pode influenciar positivamente na construção da autonomia de seus alunos, sendo uma com crianças e a outra com adolescentes, com o intuito de promover novas ações que atuem diretamente nesse processo. Discutir sobre essa temática em programas de formação docente, se torna fundamental para que os profissionais da educação possam compreender como se estabelecem as relações interpessoais dentro da escola e como o manejo dos conflitos pode influenciar na construção da autonomia dos estudantes, facilitando assim, a convivência entre eles e o desenvolvimento da criticidade. Com base na teoria piagetiana, constatou-se que o desenvolvimento moral é resultado de um processo contínuo que ocorre por meio das relações estabelecidas entre os indivíduos e que a escola, por sua vez, é um espaço privilegiado e coletivo em que as relações são exercitadas em direção a uma construção de valores socialmente desejáveis, com respeito às diversidades e igualdade, possibilitando uma convivência mais humana e democrática entre os alunos.

Nesta pesquisa, objetivou-se a analisar os principais obstáculos relacionados ao ensino e a aprendizagem da matemática no ensino fundamental, anos finais. Para a elaboração da referida pesquisa, foram necessárias uma investigação com análise qualitativa e quantitativa dos resultados da prova do SAEPE realizada em 2021. Foi feito uma vasta leitura em sites, documentos e informações atualizadas dos anos 2020/2021 disponibilizados pela Secretaria Municipal de Educação de Goiana-PE. Artigos, dissertações e teses vinculadas ao estudo da Matemática, serviram como embasamento teórico, e subsídio necessários para alcançar nossos objetivos. Obteve-se como resultados, uma visão geral dos principais problemas relacionados às dificuldades do ensino e da aprendizagem da matemática em período pandêmico. Duas turmas do 9º ano foram testadas em escolas distintas da rede pública municipal de Goiana-PE. Ficou evidenciado que a falta de hábitos de estudos regulares e aulas remotas durante todo ano de 2021, provocaram e contribuíram de forma significativa para o desinteresse dos alunos. Dentre os obstáculos e dificuldades, destaca-se em especial, a falta de interpretação das questões matemáticas. Pois, dos 13 alunos testados, apenas cinco sabiam ler e escrever com fluência. Os demais, liam e escreviam pequenas frases corretas. Provavelmente, por não saberem ler, os alunos envolvidos, apresentaram grandes dificuldades de interiorização de conteúdos e conceitos básicos que deveriam ter sido vivenciados em séries anteriores. Portanto, como possível proposta para solução ou superação desses obstáculos à longo prazo, é essencial que o professor de matemática reformule sua metodológica para a próxima etapa e retorno das aulas presenciais.

Published: January 2023

Ethnomathematics, the study of the cultural and social aspects of mathematics, has a connection to the study of music and can be useful in understanding the composition of music. Mathematics can also be used in the composition and education of music. The relationship between mathematics and music is not universally accepted, with some suggesting a strong connection and others finding minimal support for the idea. Ethnomathematics can help to make mathematics more relevant and meaningful for students, as well as reflecting the cultural diversity of classrooms, by incorporating it into the mathematics curriculum. This study aims to review the literature on the connection between ethnomathematics and music and to suggest ways in which the two fields can be connected in the classroom. (François & Pinxten, 2011; Hall, 2007; Indrawati et al., 2021; Sugianto et al., 2019), and Indrawati et al. (2021) all investigate the relationship between mathematics and various fields, such as traditional Indonesian art, multicultural education, the subfield of etnowiskunde, and Surabaya regional songs. These works emphasize the significance of cultural and aesthetic traditions in mathematics instruction and learning. By embracing such varied viewpoints, students can obtain a deeper grasp of the topic. These examples highlight the importance of integrating mathematics with other disciplines in order to expand and broaden its understanding and application.

Günümüzde küresel ve teknolojik değişimler nedeniyle iş biçimleri ve iş yapma şekilleri değişim göstermektedir. Çalışanların bu değişimlere olan tutumları işverenler açısından önem arz etmektedir. İş yaşamının geldiği noktada; çalışan ebeveynlerin artmasıyla özel yaşam ile iş yaşamı arasındaki dengenin önemi de artmaktadır. Çalışanların iş-yaşam dengelerini kurabilmeleri yaşamlarını kolaylaştırmaktadır. Örgütlerin çalışanların iş yaşam dengesini korumak için kullandıkları uygulamalardan biri esnek çalışma uygulamaları olarak karşımıza çıkmaktadır. Çalışanların algıları, ihtiyaçları ve beklentileri çerçevesinde esnek çalışmaya yönelik tutumları değişiklik göstermektedir. Bu çalışmanın amacı, çalışanların iş yaşam dengesi ve esnek çalışma uygulamalarına yönelik tutumlarının motivasyon düzeylerine etkisini araştırmaktır. Bu kapsamda Ankara Büyükşehir Belediyesi ve bağlı kuruluşu EGO Genel Müdürlüğünün merkez birimlerinde çalışan 543 kişiye anket uygulanmıştır. Araştırmada verilerin analizinde IBM SPSS Statistics 25 programından faydalanılmıştır. Ankette kullanılan verilerin güvenilirlikleri test edilmiş, faktör analizi yapılmıştır. Bağımsız ve bağımlı değişkenler arasındaki ilişkinin varlığını tespit etmek amacıyla korelasyon analizi; etkileşimi ölçmek amacıyla regresyon analizi yapılmıştır. Araştırmada değişkenler ve demografik değişkenler arasındaki farklılığın incelenmesi için Anova ve T testleri uygulanmıştır. Araştırmada esnek çalışma düzenlemelerine karşı tutum değişkeninin iş yaşam dengesi, iş sorumluluğu ve diğer çalışan tutumları alt boyutları ile motivasyon değişkeninin içsel motivasyon ve dışsal motivasyon boyutları arasında anlamlı farklılıklar tespit edilmiştir.

The purpose of this paper is to explore the mediating role of corporate social responsibility (CSR) perception on the relationship between organizational commitment and job performance in Nigeria's banking industry context. Using a self-administrated questionnaire, empirical material of the study was gathered from 208 employees working in commercial banks in the Sokoto state of Nigeria. Mediation analysis was conducted, and multiple regression analysis was used to test developed hypotheses. The findings failed to support the mediating effect of CSR perception on the relationship between organizational commitment and job performance. However, the results revealed that CSR activities toward employees positively affect organizational commitment. In contrast, CSR toward social and non-social, customers and the government has a statistically insignificant effect on organizational commitment.
El estigma de las identidades no binarias y el trastorno de estrés postraumático. Una revisión crítica de la literatura
Authors: Merino-Lorente Susana
Published: January 2023

Las identidades no binarias (NB) no se identifican completamente con construcciones binarias de género (masculino o femenino). El reconocimiento de estas identificaciones debe ser parte de los objetivos de inclusión social de cualquier democracia que respete la autodeterminación de género como elemento esencial del derecho a la libertad individual y social. En general, tienen un mayor riesgo de síntomas de trastorno de estrés postraumático (TEPT), tendencias suicidas, exposición a traumas interpersonales, trastornos por consumo de sustancias y ansiedad. Este artículo analiza y resalta la importancia identificar y eliminar la asociación de la identidad de género no binaria con la discriminación social y los factores de riesgo asociados con el TEPT. Aunque son muy pocos los estudios que incluyen estos modelos, se necesitan más investigaciones y programas familiares, sociales y psicoeducativos para promover la diversidad y la igualdad a través de respuestas adaptativas, modelos de identidad de género, conexión social, apoyo comunitario, normalización y reconocimiento legislativo.

There are many stages in the medical device management lifecycle to consider, and from the planning stage to commissioning, dismantling and decommissioning, replaceing an equipment is a critical decision. This phase includes several information that help replacement decisions intelligent. Technical, monetary and safety principles are taken into account when replacing medical equipment. One of the most frequently criterion is service life. In recent times, the delivery of a sustainable competitive advantage through the optimization of the management of non-essence activities is considered more relevant. A non-essence example is the Lifespan management of capital goods which are required in supporting the processes involved in healthcare operations ranging from acquiring assets to maximizing the operation, sustaining the performance and conclude the right time to get rid of it properly. The objective: is to identify if Total Cost Ownership (TCO) will give recommendations for decision-making even though it is capable of helping us identify the optimal economic life of the medical device. Overall, 40% of our specimens showed that monitoring TCO is essential to the continuous mapping of the cost of these devices on service.
