Modelling and Analysis of the Dispersal of a Polymeric Pollutant Injected into a Channel Flow of a Newtonian Liquid
Authors: Chinyoka Tiri , Makinde Oluwole Daniel
Published: April 2023

The transient dynamics of nonlinear dispersion of a polymeric pollutant ejected by an external source into a laminar flow of a Newtonian liquid flowing through a rectangular channel is investigated. The Boussinesq approximation is assumed for the density variation with pollutant concentration. The governing equations of mass and momentum conservation are coupled to the pollutant concentration equation as well as to the viscoelastic constitutive model for the polymer stresses. The Oldroyd-B viscoelastic constitutive model is employed to model the deformation and characteristics of the polymer stresses. The coupled system of nonlinear partial differential equations is solved numerically using robust and efficient semi-implicit finite difference methods (FDM). Solutions are presented in graphical form for various parameter values. The model can be a useful tool in understanding the dynamics of domestic and industrial pollution situations that may arise from improper discharge of long-chain hydrocarbon products into, say, water drainage systems. The novelty of this investigation is in the modelling of the long-chain hydrocarbon-product pollutants via appropriate viscoelastic (polymeric) constitutive equations. In general, it is observed that parameters which increase (decrease) the flow velocity correspondingly increase (respectively decrease) the wall shear stress. Similarly, it is observed that parameters which increase (decrease) the polymer concentration correspondingly increase (respectively decrease) the mass transfer rates. The wall shear stress and mass transfer are measurable quantities. In this respect, our work offers such measurements as predictive tools to detect the scale of contamination.

Transgressive body in Chimamanda Ngozi Adichie’s Americanah
Authors: Adeyelure Omotola T. , Roux Alwyn P.
Published: April 2023

In a society where colour is a major reason for social stratification, the black identity is burdened with the perceived negativities generated by its colour. This reality becomes conspicuous in a space defined by racial superiority and migrant status. In Americanah, unlike her other novels, Adichie migration concerns are more profound to reflect the perception and intense consequences of racial identity for African migrants and black people in the West. Through a close reading of this text from a postcolonial view, this article contends that the migrant status and blackness of African subjects, represented in physical attributes, expose their bearer to racial prejudice. This article further argues that to be integrated and access racial privileges, African migrants must suppress or eliminate the racial burdens attached to blackness by transforming or modifying their identity. Such modification evoked by a transgression is accompanied by a loss of identity.Contribution: The most outstanding feature of this article is the exploration of the interface between transgression, body and space in Chimamanda Ngozi Adichie’s (2013) Americanah. This article contributes to the growing discourse on transgression, racism and African migrants’ realities and examine the concerns of black people regarding colour politics through intercontinental migration. This article further seeks to address significant questions about the way race influences the cultural attitude of minority groups and how black immigrants react to racial Othering.

Purpose The genetic attribution for pancreatic ductal adenocarcinoma (PDAC) has been reported as 5%-10%. However, the incidence of germline pathogenic variants (PVs) in Korean PDAC patients has not been thoroughly investigated. Therefore, we studied to identify the risk factors and prevalence of PV for future treatment strategies in PDAC.Materials and Methods Total of 300 (155 male) patients with a median age of 65 years (range, 33 to 90 years) were enrolled in National Cancer Center in Korea. Cancer predisposition genes, clinicopathologic characteristics, and family history of cancer were analyzed.Results PVs were detected in 20 patients (6.7%, median age 65) in ATM (n=7, 31.8%), BRCA1 (n=3, 13.6%), BRCA2 (n=3), and RAD51D (n=3). Each one patient showed TP53, PALB2, PMS2, RAD50, MSH3, and SPINK1 PV. Among them, two likely PVs were in ATM and RAD51D, respectively. Family history of various types of cancer including pancreatic cancer (n=4) were found in 12 patients. Three patients with ATM PVs and a patient with three germline PVs (BRCA2, MSH3, and RAD51D) had first-degree relatives with pancreatic cancer. Familial pancreatic cancer history and PVs detection had a significant association (4/20, 20% vs. 16/264, 5.7%; p=0.035).Conclusion Our study demonstrated that germline PVs in ATM, BRCA1, BRCA2, and RAD51D are most frequent in Korean PDAC patients and it is comparable to those of different ethnic groups. Although this study did not show guidelines for germline predisposition gene testing in patients with PDAC in Korea, it would be emphasized the need for germline testing for all PDAC patients.

Published: April 2023

This study aimed to identify temporal and spatial patterns in the distribution of hospitalization rates for pneumonia in children under 5 years in Brazil. An ecological study was developed using data from the Unified Health System of hospitalizations for pneumonia in children under 5 years in Brazil from 2000 to 2019. Hospitalization rates per 1,000 children were calculated and Joinpoint Regression analyzed the temporal trends. Different spatial analysis techniques were performed. Annual rates of 25 hospitalizations per 1,000 children were observed in 2000 and of 13.83 per 1,000 children in 2019, with a significant downward trend for the country (annual percentage change = −3.4%; 95% confidence interval: −3.8 to −3.0) and for the regions. There was weak spatial autocorrelation; however, there were regions with high rates of hospitalization in the south region and clusters of low rates in the northeast and southeast. Clusters of areas with high hospitalization rates were observed in areas of favorable socioeconomic conditions and provision of health services in the interior of southern Brazil. There is a decreasing trend in hospitalizations for pneumonia in general; however, there are clusters of high rates in the south of Brazil.

Bacterial resistance in community-acquired urinary tract infections (UTIs) is increasing worldwide. Our study aimed to assess the microbiological epidemiology and antimicrobial susceptibility patterns of community-acquired urine bacterial isolates in French Amazonia. Our study is retrospective. It was conducted from January 2015 to December 2019 in the microbiology laboratory of the Cayenne General Hospital (French Guiana). It includes all positive urine samples from adult (> 18 years) outpatients (N = 2,533). Isolated microorganisms were Gram-negative rods in 83.9%, mainly Enterobacterales (98.4%). The main isolated bacteria were Escherichia coli (58.7%) and Klebsiella pneumoniae (13.3%). Among the isolated E. coli, 37.2% were susceptible to amoxicillin, 77.9% to amoxicillin/clavulanic acid, 94.9% to cefotaxime, 78.9% to ofloxacin, and 98.9% to nitrofurantoin. In 106 cases (5.1%), isolated Enterobacterales were extended-spectrum β-lactamase producers (5% of E. coli and 8.9% of K. pneumoniae). Overall, high levels of cross- and co-resistance were registered. The main isolated Gram-positive bacteria was Staphylococcus saprophyticus (28.9%). It was resistant to oxacillin in 52.5% of cases and susceptible to nitrofurantoin in 99.1% of cases. Patients with S. saprophyticus were young women in almost all cases. In conclusion, the most isolated microorganisms from outpatient urinalyses were E. coli and K. pneumoniae. They showed a high resistance rate to amoxicillin, but they were susceptible to the most remaining antibiotics. S. saprophyticus was isolated mainly in young women and was resistant to oxacillin in half of the cases. Interestingly, nitrofurantoin was active against most isolated organisms and can be considered as empirical treatment in uncomplicated UTIs.

Background

Spinal cord injury (SCI) is associated with an increased risk and prevalence of cardiopulmonary and cerebrovascular disease-related morbidity and mortality. The factors that initiate, promote, and accelerate vascular diseases and events in SCI are poorly understood. Clinical interest in circulating endothelial cell-derived microvesicles (EMVs) and their microRNA (miRNA) cargo has intensified due to their involvement in endothelial dysfunction, atherosclerosis, and cerebrovascular events.

Objectives

The aim of this study was to determine whether a subset of vascular-related miRNAs is differentially expressed in EMVs isolated from adults with SCI.

Methods

We assessed eight adults with tetraplegia (7 male/1 female; age: 46±4 years; time since injury: 26±5 years) and eight uninjured (6 male/2 female; age: 39±3 years). Circulating EMVs were isolated, enumerated, and collected from plasma by flow cytometry. The expression of vascular-related miRNAs in EMVs was assessed by RT-PCR.

Results

Circulating EMV levels were significantly higher (~130%) in adults with SCI compared with uninjured adults. The expression profile of miRNAs in EMVs from adults with SCI were significantly different than uninjured adults and were pathologic in nature. Expression of miR-126, miR-132, and miR-Let-7a were lower (~100–150%; p < .05), whereas miR-30a, miR-145, miR-155, and miR-216 were higher (~125–450%; p < .05) in EMVs from adults with SCI.

Conclusion

This study is the first examination of EMV miRNA cargo in adults with SCI. The cargo signature of vascular-related miRNAs studied reflects a pathogenic EMV phenotype prone to induce inflammation, atherosclerosis, and vascular dysfunction. EMVs and their miRNA cargo represent a novel biomarker of vascular risk and a potential target for intervention to alleviate vascular-related disease after SCI.

A radical reduction in power consumption is becoming an important task in the development of supercomputers. Artificial neural networks (ANNs) based on superconducting elements of spintronics seem to be the most promising solution. A superconducting ANN needs to develop two basic elements - a nonlinear (neuron) and a linear connecting element (synapse). The theoretical and experimental results of this complex and interdisciplinary problem are presented in this paper. The results of our theoretical and experimental study of the proximity effect in a stacked superconductor/ferromagnet (S/F) superlattice with Co-ferromagnetic layers of various thicknesses and coercive fields and Nb-superconducting layers of constant thickness equal to the coherence length of niobium and some studies using computer simulation of the formation of such multilayer nanostructures and their magnetic properties are presented in this article.

Reactions of neutralization occur with significant nonlinearity, which determines the control algorithms in the mode of periodic dosing of a volume of acid or alkali. Such regulation may have little effectiveness due to the fluctuation or impossibility of regulation due to insufficient or excessive concentration. This article precisely regulates the hydrogen index in mini- bioreactors and proposes the use of a digital model of the acidity management system for the selection of concentrations of topped-up solutions, determination of the regulation methodology, and improvement of accuracy pH regulation in an in vitro mini-model of the gastrointestinal tract (GIT) of a static type.

Published: April 2023

Purpose – The pressure on businesses to disclose information that goes beyond the financial aspects and includes non-financial information has grown as social, environmental, and accountability issues are receiving more attention. Integrated reporting (IR) is a technique that can close the information gap by focusing on both financial and non-financial aspects, on the linkages that already exist between the various business processes, and on the capacity of the firm to generate value over the short, medium, and long term. However, studies on the determinants of IR are limited, inconclusive, contradictory and mainly studied in developed economies. This study aimed at examining the effect of CEO ownership power on IR from a developing region perspective (East Africa). Design/methodology/approach – The study adopted explanatory and longitudinal research design with panel data to establish the causal relationship between CEO ownership power and IR. The empirical study was based on a sample of 702 firm-year observations among listed firms in East Africa for the period 2013 to 2021. Findings – The findings indicate a positively significant relationship between CEO ownership power and IR among firms listed in the East African securities exchange. Practical limitation/implications – The study used one dimension of CEO power (ownership), other studies could incorporate other dimensions of CEO power (structural, expert & prestige) and in other different contexts. From a managerial practical perspective, it shows that CEOs owning shares in the company influences the level of IR. The insights also provide useful information to shareholders and regulators in evaluating the CEO ownership power that affects IR in East Africa. This study also implies that policymakers can encourage shareholding by CEO to enhance IR. Originality/value – literature review shows a few studies have investigated the relationship between CEO ownership power and IR in the developing world specifically the East African context. This study provides empirical evidence on the impact of CEO ownership power on IR and how ownership of shares by the CEO in a firm influences the disclosure of financial and non-financial information.

A restauração da vegetação é considerada importante ação estrutural capaz de equilibrar as necessidades humanas e a dinâmica natural de corpos hídricos afetados pelo crescimento urbano desordenado. Tendo em vista que praticamente todos os rios já sofreram algum impacto ambiental, destaca-se não somente a importância de projetos de requalificação em rios urbanos degradados, como a necessidade de monitoramento temporal das soluções implementadas. Portanto, a pesquisa tem o objetivo de explorar o uso dos Sistemas de Informação Geográfica em um projeto de requalificação fluvial brasileiro (Projeto Pró-Tijuco, em São Paulo), de modo a investigar o sucesso da implantação do projeto paisagístico e demonstrar as possibilidades de uso da ferramenta. A metodologia de análise conta com o sensoriamento remoto sobre imagens satélite Planet, no software de geoprocessamento ArcGIS. A densidade vegetativa foi mapeada por método de classificação supervisionada e, em seguida, aplicou-se o índice NDVI. Os resultados permitiram constatar o espraiamento da vegetação associado à requalificação fluvial, bem como uma expressiva evolução da vegetação dentro do recorte temporal avaliado. Por fim, os mapeamentos exploram a importância da vegetação em projetos de requalificação fluvial, visto sua capacidade de impactar positivamente no monitoramento da qualidade do entorno urbano.

Data were obtained using a questionnaires and fasting blood sample collected and examined for lipid profile measurements including levels of total cholesterol TC, triglyceride TG, low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C).The mean levels of TC in groups D (179.5mg/dl) and E (180mg/dl) was higher significantly than control group subjects (156mg/dl). levels of HDL decreased in khat chewers; D and E groups (44.5mg/dl and 41mg/dl) respectively compared to the control group (46.4mg/dl).  On the other hand, the average LDL increased in the D and E subject groups (103.4mg/dl) and (112.4mg/dl) respectively compared with control 93.8mg/dl. The level of TG was increased in all study groups A, B, D and E having statistical significance p < 0.05 compared with control C. There was a higher dyslipidemia among subjects of khat chewing groups than non khat chewers in relation to increase of mean years of khat chewing. There is a significant association between chronic khat chewing and dyslipidemia especially the decrease in HDL-C level was the main lipid variable followed by TG level. The imbalanced lipid profile might be due to genetic factor or social dietary habits, besides wide spread use of pesticides during cultivation of khat plant which have toxicity in area of study.

This study assessed the level of toxic metals and hydroquinone in skin-lightening-creams commonly use in Ogun State, Nigeria. The pH of all the cream samples was determined and metals quantification was carried out using ICP-OES after acid digestion while that of hydroquinone was done using HPLC. The health risk of dermal exposure to heavy metals via the regular application was done by evaluating the carcinogenic and non-carcinogenic risk. The pH of all the samples are acidic and it follows this trend; Sample 3 > Sample 1 > Sample 4 > Sample 2. All the metals considered in this study were detected in all the analyzed samples except Cd, Co and Cr in sample 1, As, Ba and Pb in sample 2, Ag, As and Hg in sample 3 and Ba in sample 4. Highest levels of Al, Co, Pb and Zn were recorded in Sample 3 (Organic cream). Though the concentrations of most of the toxic metals (Al, Zn and Mn) are above the permissible levels, they pose no non-carcinogenic health risk based on the calculated HQ and HI. The carcinogenic risk of metals in the sampled creams were all within the acceptable limit except that of Cd. Hydroquinone was detected in all the four samples analyzed ranging between 2.58 and 4.17 % which exceeded the permissible limit by WHO. This finding show that long-term use of skin-whitening-creams may pose serious health hazards so, public should be continually enlightening on the hazardous health effects of the use.

Electrical Behavior of Lanthanum Aluminate (LAO) and Gadolinium Doped Ceria (GDG) Composite Electrolyte for Electrochemical Devices
Authors: Najim Mohd
Published: April 2023

The LAO-GDC solid composite electrolyte has been proposed for use in Solid Oxide Fuel Cells (SOFC). The material conductivity of Solid Carbonate-Ceria (SCC) composite electrolytes is 0.04Scm-1 between 400 and 700°C. For this purpose, mixtures of LaAlO3 (LAO) and gadolinium doped ceria Ce0.8Gd0.2O2 (GDC) were created in weight ratios of 3:1, 2:2, and 1:3. The composite electrolyte material was studied separately to improve conductivity. The phase structure and microstructure were studied using an X-Ray Diffractometer (XRD) and Scanning Electron Microscopy (SEM), and the electrical behavior was investigated using Impedance Spectroscopy (IS). The SEM and Energy Dispersive X-ray spectroscopy (EDX) demonstrated a compact structure with an acceptable atomic percentage of constituent elements and a uniform grain distribution. Experimental investigation showed that this composite electrolyte had a high density of LaAlO3 (LAO)-Ce0.8Gd0.2O2 (GDC) composites and an approximate 97% density of its theoretical. The electrical behavior of LAO-GDC composites had the highest value of 0.1Scm-1 at 700°C, which is more extreme than the individual conductivities of LAO and GDC, according to Electrochemical Impedance Spectroscopy (EIS) techniques. Among the three composite ratios of the system, only the weight ratio of 3:1 had better conductivity. The LaAlO3 (LAO)-Ce0.8Gd0.2O2 (GDC) composite material has a higher activation energy of 1.5eV.

The choice of a landfill site is a complex process that includes various, social, environmental, and technical, parameters which require the processing of a large amount of spatial data. The Geographic Information System (GIS), integrated with its functionalities, represents a powerful and well-adapted tool to solve this problem. This study uses the Analytic Hierarchy Process (AHP) to solve the problem of quantifying qualitative features. It enables users to make intuitive judgments about the relative eight of different predetermined criteria or options in Batna, northeastern Algeria and its neighboring municipalities. The superposition of data related to several characteristics, such as geology, hydrology, and land use, allowed us to overcome several difficulties in evaluating the location of sites suitable for establishing landfills. Results show that 88.498km2 in total meets the specified exclusion factors, of which 34.098% represent areas of very excellent suitability and 33.741% appropriate areas. Finally, low appropriateness applies to 32.161%.
Optimization of a Perovskite-based Multilayer Microwave Absorber using an Equivalent Circuit Model
Authors: Arya Aayushi
Published: April 2023

In this paper, the optimization of a perovskite-based multi-layer microwave absorber is performed to find an optimized value of the impedance step gradient from the refractive index of the constitutive layers. The optimization presented is unique as it is based on maximizing the dissipation and attenuation ability of the absorber along with a constraint of providing an efficient reflection loss in the absorber. This type of approach ensures the maximum absorption rate of the incident EM waves as the penetrating waves get fully dissipated. Objective and constraint functions are derived from the equivalent circuit model of the multi-layer absorber. The equivalent circuit model is formed using the inductive and capacitive effects across the dielectric and magnetic properties of the constitutive layers. The three layers are composed of perovskite materials with different refractive indexes such that the top layer serves as an impedance-matching layer followed by an alternate dielectric and magnetic layer. It is further shown how the capacitive and inductive losses are dominant over each other in the alternate lossy layers. Empirical relations are used to tabulate the refractive index of a range of perovskite compounds from which suitable combinations can be selected as per the obtained value of the step gradient function. The current work presents a simplistic method to design multi-layer microwave absorbers with different material combinations that are beneficial to the practical applications of microwave absorbers.

Authors: Srivastava Kartik , Kumar Ajay
Published: April 2023

This study reviews the impact of roadside friction on urban arterial roads in the published literature and aims to identify the various side frictional parameters that impact urban arterial roads. The side frictional parameters are non-motorized vehicles, pedestrian crossing or moving along the road, street vendors, on-street parking, animal movement, and land-use activity. The impact of all these parameters on traffic performance leads to a reduction in capacity, speed (instantaneous speed, journey speed, travel speed, time mean speed, and space mean speed), level of service, delay, travel time, and travel cost. This study considered online published studies from 1995 to 2022. The available effective width and the percentage reduction in road capacity are related. Road capacity is reduced by 3.37% when the effective width is reduced by 2.95%, while road capacity is reduced by 26.08% when the effective width is reduced by 21.81%.
