The Effect of Work Function of Back Contact Metals on the Performance of CdTe Solar Cells
Authors: Aliyu Mohammed M
Published: October 2024

The CdTe thin film solar cells suffer power losses at the back contact due to charge losses due
to poor mismatch of the work function of interfacing back contact materials. Thus, there is a
need to find appropriate back contact materials that do not reduce cell performance by creating
large Schottky barriers. One of the established strategies employed to reduce the barrier height
is depositing metal(s) with high work function to the CdTe back surface. In this study, we used
the average of the commonly reported values of the work function of metals, to investigate the
effects of various metals, when used as back contacts, on the performance of CdTe solar cells.
Without any other strategy employed to overcome the Schottky contacts, the solar cells'
efficiency is gravely diminished when metals with work functions lower than 5.0 eV are used.
While metals like Pt, Pd, and Au with very high work functions produce cells with efficiencies
of up to 18.6%, lower work functions metals like Al almost completely diminished the
efficiency to less than 0.5%. our findings indicate that the Schottky barrier affects mainly Voc
and FF, as Jsc showed only a slight reduction. When subjected to extreme operating
temperatures, the efficiencies largely decreased with temperature. Temperature coefficients of
-0.3 to -0.45/oC have been obtained, for the highest-performing metals.

Published: October 2024

The introduction of noble metal nanoparticles in solar cells has been proven to enhance the
performance of perovskite solar cells. In this study, silver-modified photoanodes were utilized
to improve the performance of perovskite solar cells through successive ionic layer adsorption
and reaction (SILAR) procedures. Due to the surface plasmon resonance effect, the light
trapping capacity of the device was enhanced with superior photovoltaic properties. The
plasmonic effects of the introduced silver nanoparticles (AgNPs) were explored using SEM,
XRD, UV-visible absorption spectrophotometer and solar simulator. The SEM results show
compact morphologies and shinning surfaces indicating the presence of AgNPs. The XRD
result shows a good crystal phase. The UV-vis results show enhanced optical absorption with
AgNPs incorporation. The photovoltaic characteristics of the fabricated PSCs are: (i) pristine
device; Jsc of 6.440 mA/cm2, Voc. of 0.948 V, FF of 0.642 and PCE of 3.917%, (ii) device
with 1 SILAR of AgNPs; Jsc of 014.426 mA/cm2, Voc. of 0.949 V, FF of 0.642 and PCE of
8.795%, and (iii) device with 2 SILAR of AgNPs; Jsc of 10.815 mA/cm2, Voc of 0.917 V, FF
of 0.558 and PCE of 5.536%. The device with the best performance is made of 1 SILAR cycle
of AgNPs which shows an enhancement of ~2.245 times in PCE, ~2.240 times in Jsc and
~1.001 times in Voc over the reference device. The results in this study have unlocked the
beneficial role of AgNPs and further contribute to understanding surface plasmon effect due to
AgNPs introduction.

Authors: Shaharuddin Hanis Najwa , Raup Fudzla Suraiyya Abdul , Shafri Muhammad Hatta , Sanusi Siti Saleha
Published: October 2024

This study examines the motivations driving undergraduates at Universiti Teknologi Mara (UiTM) in Malaysia to learn foreign languages, addressing the challenges and issues associated with language learning in the country. Although foreign languages are introduced early in Malaysian primary schools, student motivation often declines as they advance to university, and achieving satisfactory language proficiency remains a challenge. Building on previous research, this study highlights the importance of both intrinsic and extrinsic motivation in language learning. Integrative motivation, which involves a desire to connect with and understand foreign cultures, and instrumental motivation, which focuses on practical benefits such as career advancement, are identified as key factors. Additionally, the study underscores the significance of attitudinal motivation, which includes students’ attitudes towards their learning environment, such as teacher effectiveness, course content, and peer interactions. These motivational factors are interconnected and collectively influence students’ engagement and success in acquiring foreign languages, reflecting the complexity of language learning motivation. Using a quantitative approach, the study surveyed 254 students from a population of 2,590 enrolled in Arabic, German, French, and Japanese courses at UiTM, employing a questionnaire based on the Foreign Language Learning Motivation Questionnaire (FLLMQ-6). The findings reveal that the strongest motivators are the desire to become global citizens and to understand foreign cultures, with career and economic benefits also playing a significant role. However, students show less motivation to fully integrate into foreign cultures and feel uncomfortable speaking foreign languages in formal settings. In contrast, they are strongly motivated to learn foreign languages for the purpose of communicating with foreigners, indicating greater comfort interacting in informal settings. The study recommends creating supportive, low-pressure learning environments, incorporating culturally immersive activities, and providing real-world communication scenarios to better align with students’ motivations. These insights are essential for refining language education policies and practices to better address the needs of diverse learners in a globalized context.
AfCFTA and Economic Integration in Africa: Issues in Implementation and Development
Authors: Tochukwu Okeke , Abraham Ameh
Published: October 2024

The African Continental Free Trade Area Agreement (AfCFTA) is renowned as Africa’s most current and comprehensive approach to economic integration since the sidetracking of the Abuja Treaty of 1994 which established the African Economic Community. Although touted as having the potential of transforming African economies in the 21st century, the free trade agreement faces a number of challenges in Africa’s ecosystem, with which it must contend. These include but not limited to digital infrastructure deficits, poor government policies, limited trade/market access in Africa, security challenges, poor border governance, diseases spread, etc. To varying degrees, those challenges impact the implementation of the AfCFTA and regional economic integration/development. Examining how and why AfCFTA is impacted represent the main thrust of this paper. The study employs a conceptual/thematic approach and integrates qualitative data from primary and secondary sources in interrogating the subject of regional economic integration in Africa. The research found that the challenges confronting AfCFTA are not just crippling, they are existential. These crises first affect African entrepreneurs directly and, by extension, undermine the implementation of the AfCFTA since its ratification. Thus, more robust and broad ranging strategies are required to review, recalibrate and advance the AfCFTA.

Published: October 2024

This study aim to explore challenges that face the effective use of pedagogical strategies used by teachers in enhancing mathematics performance of standard four pupils with Moderate Intellectual Disability (MID) in Inclusive Settings. The study involved 80 respondents whereby 40 were mathematics teachers, 8 heads of schools and 38 pupils with moderate intellectual disabilities selected from eight inclusive primary schools. The study employed a case study research design (qualitative research approach) in which data were collected using interviews, focus group discussion, observation and documentary review. The data from focus group discussion, interviews and observation were coded by using qualitative data analysis software called NVivo. Findings of this study established that there were various challenges which hindered effective utilization of the pedagogical strategies identified in this research. Among those challenges were: inadequate number of qualified teachers coupled with poor resources allocation (both material and human resources). It was further discovered that, the nature of classrooms which seemingly appeared overcrowded together with high teacher-pupil ratios were among the challenges. For example, on average a class was observed to accommodate 113 pupils inclusive. Based on these findings, the study recommends that the school management should organize indoor seminars and workshops to empower teachers with the current teaching and learning strategies and this could better be facilitated by the respective Council.

Published: October 2024

Teacher talk is a prominent aspect that fosters active learning and student engagement in the ESL classroom. (Starr, 2017). Therefore, this study intends to examine the sociolinguistic dimensions of the language; employed by English as a Second Language (ESL) teachers. The research also analyses teacher language (teacher talk) and behavior specifically in relation to bilingualism, code-switching and gender differences. Following a qualitative approach this study used classroom observation to gather data which were then analyzed using thematic analysis with an emic perspective. The findings of the study highlighted the usage of bilingualism and code-switching in between English (L2) and teacher’s native language (L1) Sinhala. Further, gendered language behaviors and the presence of speech act theories in teacher talk inside the ESL classroom is also analysed. Furthermore, this research examines how linguistic choices influence the dynamics of teacher-student communication and cooperation in the classroom. By contributing to an in-depth understanding of the symbiotic relationship between language use and sociolinguistics theories prominent in ESL teaching context, this study recommends further research in the fields involving instructional language in ESL classrooms and ESL teacher training.
The Portrayal of Education as a Double-Edged Sword in “Weep Not, Child“.
Authors: Ladzekpo Gershon Kofi
Published: October 2024

The study aims to explore the dualistic portrayal of education in Ngũgĩ wa Thiong’o’s novel “Weep Not, Child”, where education is depicted both as a tool for liberation and a mechanism for systemic control. Employing a qualitative literary analysis methodology, the research delves into the narrative, character development, and thematic elements to unpack the complex relationship between education and the sociopolitical context of colonial Kenya. Findings reveal that education in “Weep Not, Child” is presented as a transformative force that enables characters like Njoroge to envision personal and societal progress. However, it simultaneously serves as a double-edged sword, perpetuating colonial ideologies and deepening existing social divides. The study highlights instances where education acts as a beacon of hope and instances where it reinforces subjugation and despair. Overall, the portrayal of education in the novel underscores its inherent contradictions, reflecting the conflicted realities of colonial Kenya. The implication of this research is significant for postcolonial studies, emphasizing the need to critically evaluate educational systems within historically oppressive contexts and to acknowledge their potential to both empower and control. This dual perspective advocates for an educational framework that not only promotes personal growth and societal advancement but also conscientiously addresses and dismantles structures of inequality and colonial imposition. Further, the study suggests a reevaluation of educational content and systems in post-colonial nations to ensure they serve as true instruments of freedom and development rather than perpetuating historical injustices.

Authors: Aydinlik Soner , Kiris Ahmet
Published: October 2024

We proposed a novel technique to obtain highly accurate solution to the problem of an irreversible exothermic chemical reaction occurring in an adiabatic tubular chemical reactor. The study also delves into the convergence behavior and error analysis of this technique. Furthermore, we investigate the approximation of the steady-state temperature of the reaction under various scenarios involving the Peclet and Damkohler numbers, and the dimensionless adiabatic temperature rise. To validate our findings, we compare our results with those obtained using several other established methods, including the Taylor and B-Spline Wavelet Methods, Adomian Method, Shooting Method, Contraction Mapping Principle, Sinc-Galerkin Method, and Chebyshev Finite Difference Method. These comparisons affirm that our proposed technique yields solutions that are not only accurate but also stable and efficient when applied to the specified model.

Wounds that become infected can lead to serious illness or even death if left untreated. Unfortunately, current wound healing treatments don’t always work well. Achieving optimal wound healing involves the coordination of diverse cellular events facilitated by numerous growth factors, cytokines, and chemokines. One potential solution for addressing the wound healing process is using lyophilized-secretome gel from human Wharton’s Jelly Mesenchymal Stem Cells (hWJMSCs-Sec). This gel, called lyophilized-hWJMSCs-Sec gel (LSG) is created by mixing carbomer gel with hWJMSCs-Sec, then freeze-dry it into a powder to maintain its quality and stability. The quality testing of the topical gel formulation is conducted by measuring. The gel is tested for pH, viscosity, consistency, and its appearance. It’s also tested for antioxidant activity using 2,2-Diphenyl-1-picrylhydrazyl (DPPH), and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays were employed to identify the antioxidant activities of the lyophilized-gel. Proteins level of Tissue Inhibitor of Metalloproteinases-2 (TIMP-2), Epidermal Growth Factor (EGF), basic Fibroblast Growth Factor (bFGF), Interleukin-6 (IL-6), and IL-4 were also measured with the ELISA method. The LSG has a soft and non-sticky texture with clarity, a pandan-like aroma, and excellent adhesion and spreadability. It contains proteins and antioxidants that help wound healing. The lyophilized-Sec gel contained TIMP-2, EGF, bFGF, IL-6, and IL-4 as well as stronger antioxidant properties compared to un-lyophilized-hWJMSCs-Sec gel, and showed promise as an effective remedy for wound healing.
HIGHLIGHTS

Assessment of the mechanism of action underlying the wound healing effects of the gel, such as its influence on cellular processes, growth factor release, and antioxidant activity.
Investigation of the secretome combination with carbomer gel in providing a convenient application for wound treatment.
Preservation of active ingredients in the secretome through lyophilization, ensuring stability and enabling extended storage duration.

Authors: Dr. Kunjan Singh Songara  , Dr. Dolly Barhaiya  , Dr. Rani Barhaiya
Published: October 2024

It is deal with a research paper, there has been a growing interest in using polymers with antibacterial and antifungal properties; therefore, the present review is focused on the effect of natural compounds on the antibacterial and antifungal properties of polyurethane (PUR). This is very important because materials and objects made with this polymer can be used as antibacterial and antifungal ones in places where hygiene and sterile conditions are particularly required and thus can become another possibility in comparison to commonly used disinfectants, which mostly show high toxicity to the environment and the human health. This topic also presents the possibilities of using natural extracts as antibacterial, antifungal, and antiviral additives, which, in contrast to the currently used antibiotics, have a much wider effect. The different kinds of fungi, but they cannot fight viruses; therefore, compounds of natural origin can find wide use as biocidal substances. Fungi grow in almost any environment, and they reproduce easily in dirt and wet spaces; thus, the development of antifungal polyurethane foams is focused on avoiding fungal infections and inhibiting growth. The ability of micro-organisms to grow on polyurethanes can cause human health problems during the use and storage of polymers, making it necessary to use additives that eliminate bacteria, viruses, and fungi.
El daño social como nueva tipología de daño resarcible
Authors: De Cicco Maria Cristina
Published: October 2024

Este trabajo parte del supuesto de la correspondencia entre la exigibilidad de los derechos y los deberes de solidaridad y, por lo tanto, de la responsabilidad y plena realización de la persona como fundamento del ordenamiento jurídico italiano. Sobre esta base, se propone que los daños derivados de actos de corrupción y del incumplimiento de las normas impuestas para contener la propagación del virus SARS-CoV-2 puedan configurarse en el sistema italiano de responsabilidad civil como daños sociales, en la medida en que ambos supuestos conducen a una pérdida de valor que se refleja en la degradación del bien común. El fundamento de esta propuesta se encuentra en la cuestión de la ética del comportamiento, ya que el incumplimiento de los deberes provoca un daño irreparable en relación con las necesidades de solidaridad social, con grave violación de los artículos 2º y 3º de la Constitución, causando así un perjuicio a la sociedad.

Enhancing the Textbook’s Cultural Content within the University Museum: Students’ Perceptions of Two Activities
Authors: Marcos Miguel Nausica , Hancock Megan
Published: October 2024

The authors, a language instructor and a museum educator, collaborated to enhance a textbook’s cultural content in a Spanish L2-third semester class. We integrated the university museum’s artifacts and one exhibition within regular classroom instruction and co-designed two activities. The activities were connected to the textbook’s cultural content. Each activity included a visit to the museum, a worksheet to work in the museum, and a written and oral task after the visit. Thirty-five students completed a questionnaire at the end of the semester to rate the integration of these museum visits with the rest of the Spanish curriculum. Most students were positive about the effects of the experience on their learning and did not see the activities as something extraneous to the language curriculum. This article offers food for thought to other language practitioners and museum educators regarding textbooks’ cultural content and university museums.
Saquetti, doble instancia y régimen casacional contencioso-administrativo: el gran oxímoron procesal
Authors: Cancio Fernández Raúl C.
Published: October 2024

La sentencia del Tribunal Europeo de Derechos Humanos (TEDH) de 30 de junio de 2020 (caso Saquetti Iglesias c. España) ha venido a comprometer severamente la racional aplicación por la Sala Tercera del Tribunal Supremo del vigente régimen casacional en el orden contencioso-administrativo, tensionándolo dramáticamente al exigirle cohonestar las garantías contempladas por el artículo 2 del Convenio para la Protección de los Derechos Humanos y de las Libertades Fundamentales (CEDH) de 22 de noviembre de 1984 (Instrumento de ratificación del protocolo n.º 7) en caso de impugnación de sanciones administrativas de naturaleza penal impuestas en única instancia, con las pautas rituales contempladas por la ley de la jurisdicción, configurando ex novo y contra legem una suerte de presunción de interés casacional a los efectos de la admisión del recurso, y obligando a la Sección de Admisión a optar, a la hora de resolver sobre la viabilidad de un recurso de casación, entre abrazar incondicionalmente la doctrina Saquetti o aplicar con rigor las exigencias procesales del régimen casacional, incompatibles con el mandato de Estrasburgo, que demanda de la Sección de Enjuiciamiento pronunciarse sobre elementos probatorios, factuales y valorativos ontológica y teleológicamente ajenos al espíritu del sistema casacional introducido por la Ley orgánica 7/2015, cuyo elemento basal, el interés casacional objetivo, queda necesariamente debilitado.

La tuberculosis sigue siendo una epidemia mundial y en Chile no ha mostrado una tendencia descendente en los últimos años, con un aumento en los casos infantiles. En los niños, el diagnóstico es un reto debido a la baja carga bacilar y las características de las lesiones, que suelen ser cerradas. Métodos tradicionales como los cultivos, considerados anteriormente como el gold standard, con frecuencia arrojan resultados negativos. Sin embargo, los avances en pruebas moleculares han permitido un progreso significativo en la confirmación bacteriológica. Otras herramientas diagnósticas, como la prueba de tuberculina (PPD) y los ensayos de liberación de interferón gamma (IGRAs), tienen sensibilidades y especificidades variables, siendo útiles como pruebas complementarias. Las imágenes juegan un papel clave en la evaluación diagnóstica de tuberculosis pulmonar y extrapulmonar en pacientes pediátricos. Esta revisión aborda la epidemiología y el proceso diagnóstico de la tuberculosis infantil.

Background and Aim. The аrticlе deаls with the problem of the use of residual veterinary drugs in animal husbandry and poultry farming. In thе mоdern wоrld, thе use of antibiotics in animal husbandry is a common problem. However, their use is often uncontrolled and can lead to contamination of fооd prоducts of animal оrigin with medicines. Within the framework of this work, the contamination of rаw mаterials of animal origin and food products sоld on the territory of Kazakhstan has been studied.Materials and Methods. The studies were conducted by enzyme-linked immunoassay (hereinafter referred to as ELISA) to determine the permissible levels of residual content of veterinary drugs. The studies took into account the content of residual amounts of pollutants such as chloramphenicol, sulfamethazine, nitrofuran 3-amino 5morpholinomethyl-2oxazolidinone (AMOZ), bacitracin in rаw materials of аnimаl origin: horse meat, pork, poultry, beef, lamb. The use of the ELISA method for the anаlysis оf thе contеnt of antibiotics in meat allows for accuracy and reliability in determining the residues of veterinary drugs. This is necessary to comply with regulatory requirements and ensure the safety of meat products consumption.Results. Our results show that the residual levels of antibiotics in animal raw materials are within the permissible limits. This is аn impоrtant conclusiоn fоr foоd safеty.
Conclusion. Based on the studies conducted in this work, monitoring of antibiotic residue in animal raw materials, it can be concluded that, their use in livestock and food production should be monitored continuously.

One of the most effective technical solutions for improving the quality and quantity of seed production as well as other yield-related parameters in the brassica variety is the heterosis breeding strategy. Ten different genotypes of Indian mustard were used in the current study to examine heterosis in the crop. These genotypes included NRCHB 101, DRMR-IJ-31, Kanti, Urvashi, Pusa mustard-25 (NPJ-112), Pusa mustard-26 (NPJ-113), Pusa mustard-27 (EJ-17), CS 54, RH 406, and RH 749. The pure lines were maintained through selfing over a number of generations. This produced 45 F1s and 45 F2s that were evaluated in a Randomized Block Design with three replications during the Rabi season of 2017–20 at the Agriculture Research Farm of School of Agricultural Sciences and Engineering, IFTM University, Moradabad (U.P.), India. These lines were crossed in a half-diallel fashion at Agriculture Research Farm of R. B. (PG) College, Agra, (U.P.), India. Quantitative character data was documented, and hybrid per se performance, heterosis, and inbreeding depression were identified. The crosses with the greatest levels of conventional heterosis and considerable negative heterobeltiosis were PM 27×RH 406, RGN-48 x Kranti, and Kanti×Urvashi. These crosses were also the first to mature. Based on the hybrid’s performance, it can be inferred that either parent’s dominant effect in expressing the trait during the F1 generation or high heterosis for the number of siliquae per plant contributed to the hybrid’s significant positive heterobeltiosis and standard heterosis for seed yield per plant, RH 406×RH 749. The lack of inbreeding depression for oil content in the hybrids resulting from the crossings NRCHB 101×DRMRIJ 31, NRCHB 101×PM-27, DRMRIJ 31×PM-27, and DRMRIJ 31×RH-749 may be caused by low heterosis and additive variance caused by the parents’ weak combining ability. These F1s may be exploited for obtaining transgressive segregants for the development of hybrid varieties in Indian mustard.

The study appraised quality assurance practices as determinants of lecturers’ role performance in Colleges of Education in Cross River State, Nigeria. Four research questions were posed and converted to null hypotheses that guided the study. The research design adopted for the study was a correlational research design. The population comprise 485 lecturers from which a representative sample of 242 was proportionately drawn from college of education (COE) Akamkpa and federal college of education (FCE), Obudu. Researcher developed questionnaires titled “Quality Assurance Practices Questionnaire (QAPQ)” and Lecturers’ Role Performance Questionnaire (LRPQ)’ were used for data collection. Data collected were pilot tested using Cronbach’s reliability and the coefficients obtained range from .75, 82, .85, and .89. The hypotheses were tested with simple and multiple regression analysis and the findings showed thus: staff training, adherence to students’ admission policy and provision of teaching-learning facilities significantly predict lecturers’ role performance individually and there is a significant collective prediction of lecturers’ role performance on staff training, students’ admission policy and provision of teaching-learning facilities. The study recommends that regular training such as workshop, seminar and conferences should be organized for lecturers. Also, that provision should be made for availability of teaching-learning facilities and lastly, colleges should adhere to students’ admission policy.
