Published: July 2022

ABSTRACT. The mechanical attachment method was used to modify the glass carbon electrode (GCE) with polyaniline nanoparticles (PANI NPs) to produce a new nanosensor (PAN NPs/GCE). Electrochemical properties was studied by a new nano working electrode using cyclic voltammetric (CV) technique to develop the oxidation – reduction reaction. K4[Fe(CN)6] solution is one of the standard solutions for CV titration by redox peak current of FeII/FeIII in KCl solution as electrolyte, which can be used to study different concentrations, scan rates, pH, diffusion coefficient (Df) and reliability and stability PAN NPs/GCE modified electrode. The CV results of the new PANI NPs/GCE nanosensor have two peaks at 400 and 200 mV for oxidation-reduction FeII/FeIII, respectively. The current ratio value of the new PAN NPs/GCE was found to be Ipa/Ipc ≈ 1 with a separation peak of ∆Epa-pc = 200 mV. From these results, the nanosensor acts as an irreversible and heterogeneous reaction. Other electrochemical properties of the new sensor have a low detection limit of K4[Fe(CN)6]. In addition to the highly enhancement of the redox peak current in acidic pH, it was obtained good stability of nanomaterial on the electrode.

Authors: Legese Wubishet , M. Taddesse Abi , Teju Endale 
Published: July 2022

ABSTRACT. Excess quantities of fluoride and phosphate in water bodies can lead to fluorosis and eutrophication problems, respectively. In search of a promising adsorbent targeting these ions, Fe3O4/Al2O3/ZrO2 ternary oxide was synthesized via co-precipitation method and characterized by X-ray diffraction (XRD), Fourier transform-infrared (FTIR) and Brunauer-Emmer-Teller (BET). Its specific surface area was found to be 205 m2/g. The effects of solution pH, adsorbent dose, contact time, agitation speed and initial fluoride and phosphate concentrations were also investigated and the optimum values were 4, 0.5 g, 12 h, 100 rpm and 20 mg/L, respectively, for fluoride and 5, 0.1 g, 8 h, 100 rpm and 10 mg/L, respectively, for phosphate. Fluoride and phosphate adsorptions fitted well with Freundlich and Langmuir isotherm models, respectively and their kinetic data correlated well with the pseudo-second order model. Desorbability study revealed that maximum desorption was achieved at pH 12. Thermodynamics study on the other hand showed that adsorption of fluoride was nonspontaneous and endothermic whereas that of phosphate was spontaneous and exothermic. Application on real water sample decreased the concentration of fluoride from 4.92 to 1.97 mg/L in ground water and phosphate from 1.7 to 0.35 mg/L lake water showing its potential as a promising adsorbent.

Published: July 2022

ABSTRACT. This work focused on the extraction of “water hyacinth leaf protein concentrate” (WHLPC) and preparation of polypyrrole (PPy), polyaniline (PANI) and polypyrrole-polyaniline copolymer (PPy/PANI) coated WHLPC by in situ polymerization and investigate their application for the removal of Cr(VI) from aqueous solution. After optimizing the experimental conditions like pH, adsorbent dosage, contact time and initial concentration it was found that the kinetics and isotherm data were well fitted to the pseudo-second-order and Langmuir models, respectively. PPy/PANI/WHLPC was found to be an efficient material compared to the other polymer-coated adsorbents with maximum adsorption capacity of 230 mg/g. The presence of counter ions ((NO3-, Cl-, HPO42-, SO42+ and HCO3- ions) slightly decreases the Cr(VI) removal efficiency PPy/PANI/WHLPC. The thermodynamic study reveals that the adsorption of Cr(VI) onto PPY/PANI/WHLPC is endothermic, thermodynamically feasible, and spontaneous. In addition, reusability of the material indicated high removal efficiency for two adsorption cycles.

Authors: Ajayi O. O. , Charles-Davies M. A. , Inetor J. I. , Ademola A. F. 
Published: July 2022

INTRODUCTION: Many studies on female breast cancer patients do not consider the differences between the follicular and luteal phases when collecting blood samples for laboratory investigations. Therefore, this study was designed to investigate the effects of the phases of the menstrual cycle on reproductive and thyroid hormones, endocrine disruptors, blood pressure, and body adiposity.
METHODS: Participants (n=107) aged 28-50 years, comprising 54 newly diagnosed breast cancer patients (cases were menstrual phase and age-matched to 53 seemingly healthy women without breast cancer that served as controls. Anthropometric indices and blood pressure (BP) were obtained. Serum hormones-estradiol, progesterone, luteinizing hormone (LH), free triiodothyronine (FT3), thyroid-stimulating hormone (TSH), stimulating follicle hormone (FSH), and free thyroxine (FT4) were quantified by enzyme immunoassay. Endocrine disruptors (EDs)- arsenic, lead and cadmium were quantified by atomic absorption spectrophotometry (AAS). Data were analyzed using Student’s t-test and Pearson correlation coefficient with p<0.05 considered significant.
RESULTS: Bodyweight, hip circumference, waist-height ratio, and FT3 varied between the luteal and follicular phases, higher in cases than controls. EDs were significantly higher in cases than controls in both phases. Progesterone, estradiol and LH levels were significantly higher in luteal cases and controls when compared with follicular cases and controls.FT3 was significantly lower in luteal controls compared with follicular controls. There were significant direct and inverse correlations among adiposity measures, BP, EDs, and hormones in each phase in both cases and controls.
CONCLUSION: The menstrual cycle appears to influence blood pressure, measures of adiposity, endocrine disruptors, and reproductive hormones in women with normal and cancerous breasts. This requires consideration in the collection of blood samples for investigations of these parameters.

Published: July 2022

Extensive research has been conducted regarding socio-emotional skills training in autism spectrum disorder (ASD). The latest autism research is now beginning to recognize the role of metacognitive deficits in ASD as well as the importance of metacognitive skills training in autism intervention. The purpose of the current review study is to shed light on the role of metacognition in ASD and identify assistive technologies that may compensate for metacognitive deficits in ASD. Specifically, we examine autism through the lens of the models of metacognition developed by (Drigas and Mitsea, 2020;2021). Following these metacognitive models, we identified digital technologies that have the significant potential to train metacognitive skills in people with ASD. These technologies include, among others, robotics, virtual reality, mobile applications, digital serious games, coding digital games and robots. This review provides evidence that people with autism face important difficulties in almost all metacognitive domains. It also highlights that digital technologies are effective tools for training metacognitive skills in ASD. This study is one of the few studies that deal with autism as a disorder of metacognition and gives pointers for future experimental research regarding intervention strategies with the assistance of technologies.

A conceptual-model-based sediment connectivity assessment for patchy agricultural catchments
Authors: Batista Pedro V. G. , Fiener Peter , Scheper Simon , Alewell Christine 
Published: July 2022

Abstract. The accelerated sediment supply from agricultural soils to riverine and lacustrine environments leads to negative off-site consequences. In particular, the sediment connectivity from agricultural land to surface waters is strongly affected by landscape patchiness and the linear structures that separate field parcels (e.g. roads, tracks, hedges, and grass buffer strips). Understanding the interactions between these structures and sediment transfer is therefore crucial for minimising off-site erosion impacts. Although soil erosion models can be used to understand lateral sediment transport patterns, model-based connectivity assessments are hindered by the uncertainty in model structures and input data. Specifically, the representation of linear landscape features in numerical soil redistribution models is often compromised by the spatial resolution of the input data and the quality of the process descriptions. Here we adapted the Water and Tillage Erosion Model and Sediment Delivery Model (WaTEM/SEDEM) using high-resolution spatial data (2 m × 2 m) to analyse the sediment connectivity in a very patchy mesoscale catchment (73 km2) of the Swiss Plateau. We used a global sensitivity analysis to explore model structural assumptions about how linear landscape features (dis)connect the sediment cascade, which allowed us to investigate the uncertainty in the model structure. Furthermore, we compared model simulations of hillslope sediment yields from five subcatchments to tributary sediment loads, which were calculated with long-term water discharge and suspended sediment measurements. The sensitivity analysis revealed that the assumptions about how the road network (dis)connects the sediment transfer from field blocks to water courses had a much higher impact on modelled sediment yields than the uncertainty in model parameters. Moreover, model simulations showed a higher agreement with tributary sediment loads when the road network was assumed to directly connect sediments from hillslopes to water courses. Our results ultimately illustrate how a high-density road network combined with an effective drainage system increases sediment connectivity from hillslopes to surface waters in agricultural landscapes. This further highlights the importance of considering linear landscape features and model structural uncertainty in soil erosion and sediment connectivity research.

Authors: GoÑl-Alsúa Edurne 
Published: July 2022

ABSTRACT
Bernard Shaw has been a well-known writer in the Spanish-speaking world since Julio Broutá introduced his works in Spain at the beginning of the twentieth century. This article assesses two of the six translations of his play Pygmalion into Spanish, those of Julio Broutá (1919) and Floreal Mazía (1952), focusing specifically on the rendering of Cockney. Both target authors maintain the dialectal distinction in their works, by translating Cockney as Cheli and Lunfardo, dialects spoken by the lower classes of Madrid and Buenos Aires, respectively.

El estado de excepción declarado en Ecuador por efecto de la pandemia mundial provocada por el virus SARS-CoV-2, denominado covid-19, puso a los habitantes en una situación de alerta para evitar los contagios, causando un cambio en la decisión del uso de transporte público por el transporte privado. El objetivo de esta investigación fue determinar la relación que existe entre la calidad del servicio de transporte de taxis y la decisión del traslado frente a la emergencia sanitaria en la ciudad de Guayaquil.
La investigación fue aplicada, cuantitativa, no experimental, correlacional. La muestra fue tomada a 385 habitantes de la ciudad de Guayaquil. Se aplicó un cuestionario con 33 interrogantes en escala de Likert y el análisis estadístico se realizó con el software SPSS.21. La fiabilidad del instrumento se respalda por el valor obtenido de 0.955 coeficiente alfa de Cronbach. El coeficiente de Spearman obteniendo (p = 0.315) muestra una correlación positiva débil entre las variables de estudio. Si bien la relación de los factores no es contundente, los resultados o percepciones obtenidos individualmente, incita en reforzar la edificación de una cultura de servicio propicia en los usuarios ante la decisión de trasladarse en taxi en épocas de pandemia, considerando el alto porcentaje de inseguridad existente en la ciudad de Guayaquil, Asimismo, el estudio determina que no existe la seguridad en el servicio recibido por parte de los taxistas informales, generando robos, secuestros express, y creando incredibilidad y desconfianza al pasajero.
Analysis The Participation of Enterprise In Sustainability Under the ESG Criteria From The Perspective of Game Theory
Authors: Su Fanrong 
Published: July 2022

In this paper, I use the evolutionary stable strategy and mixed strategy to construct a game model for both sides from three aspects of ESG and derive the relevant evolutionary stable strategy through a simple replicated dynamic analysis. Then use the Matlab to make a simulation about their evolution of strategy probability. The E-side is a game between the choice of the enterprise’s green innovation and governmental responsibility, the S-side is a game between the enterprise’s responsibility and employee’s loyalty, and the G-side is a game between the enterprise’s sustainable internal management and continued investment by investors. The consideration of these aspects of the game is used to construct a game model. The analysis of the mixed and evolutionary stable strategy can be used for the choice of strategy between the two players in different situations, which can be used as a reference when an enterprise is facing the strategy for its management.
Le fondazioni greche di Magna Grecia e di Sicilia in rapporto con gli insediamenti indigeni preesistenti
Authors: Guzzo Pier Giovanni 
Published: July 2022

Le fondazioni greche di Magna Grecia e di Sicilia in rapporto con gli insediamenti indigeni preesistenti. Si discutono i modelli mentali ellenici, ricavati dalle fonti letterarie, relativi alle forme delle fondazioni in Occidente. Si ritiene che tali fondazioni siano state operazioni condotte dalle poleis e non da privati. Si confrontano le strutture, archeologicamente note, delle fondazioni greche occidentali con quelle degli insediamenti indigeni. La mancanza di condizionamenti territoriali e cultuali, insieme alla impostata regolarità dei lotti agricoli, ha condotto a forme urbanistiche che, dalle poleis occidentali sono state imitate in Grecia propria.

The Greek foundations of Magna Graecia and Sicily are discussed in relation to the pre-existing indigenous settlements: the Hellenic mental models, as drawn from literary sources, in relation to the forms of foundations in the West. Evidence indicates that these foundations were operations conducted by the poleis and not by private individuals. The archaeologically known structures of western Greek foundations are compared with those of the indigenous settlements. The lack of territorial and religious conditions, together with the set regularity of agricultural lots, led to urban planning forms that derived from the western poleis and were imitated on the Greek mainland.
