O fogo e os profetas: a presença bíblica em 'A Circle in The Fire', de Flannery O'Connor
Authors: Francisco Thiago
Published: June 2024

O presente artigo analisa a presença de aspectos literários do texto bíblico no conto A Circle in The Fire da escritora estadunidense Flannery O´Connor. O conto narra o confronto entre uma rica proprietária de terras com um grupo de três adolescentes que passam a importunar a mulher com um comportamento insubmisso dentro das propriedades dela. Nesta análise, as considerações de Robert Alter (2007) e Northrop Frye (2004 e 2006) servirão de base teórica para as considerações que serão feitas a respeito do texto bíblico enquanto obra literária. Após apresentarmos um panorama dos estudos literários a respeito da Bíblia, investigaremos como o conto de O'´Connor se apropria de algumas imagens e temas bíblicos — mais especificamente, as figuras dos profetas e o arquétipo do fogo — para o desenvolvimento de seu conto. O nosso objetivo é demonstrar que uma interpretação adequada da obra de O´Connor deve levar em consideração as profundas relações que existem entre a obra da autora e o texto bíblico.

Authors: Ndegerege Moses , Wanyoike Rosemarie
Published: June 2024

The implementation of a Human Resource Information System (HRIS) at the Teacher's Services Commission was anticipated to enhance operational efficiency and therefore decrease the volume of communication and client visits to the commission at any given moment. The main aim of this study was to examine the relationship between human resource information systems and employee performance within the context of TSC. The study holds significance for the administration of TSC, the staff of TSC, public organizations, users of HRIS, and other researchers. The study is based on Ability-Motivation-Opportunity Theory, Social Systems Theory, Technology Acceptance Theory, Wage Fund Theory, and Resource Flow Theory. The research employed a descriptive research design. Target staff for this research constituted 144 staff at TSC secretariat. The study used purposive sampling to determine the specific TSC Secretariat that primarily focuses on use of HR systems for staff management. Consequently, the sample size remains 144 participants. The utilization of both structured and unstructured questionnaires was towards collection of primary data. The study instrument's validity was assessed using content validity, face validity, construct validity, and consultation with the supervisor and expert opinions. The reliability tests utilized Cronbach's Alpha Coefficient, with a threshold of 0.7. Descriptive statistics, such as the standard deviation and mean, was applied. The application of inferential statistics, specifically multiple linear regressions, was facilitated by the use of SPSS software. Analysis was conducted at a significance level of 0.5. The data that was evaluated was presented using tables in order to enhance the clarity of the findings. Presenting qualitative data involved the narrative presentation of narration derived from content analysis. According to the findings, the HRIS payroll interface in e-payroll is capable of calculating salaries and providing a variety of supporting jobs when it is coupled with payroll administration. It was emphasized that online recruiting makes available a number of methods for screening persons. These methods include pre-employment screening, personality evaluations, and testing, and they make it possible to choose suitable applicants who are a reflection of an organization's beliefs. Although e-appraisal systems influence human resource information systems and employee performance at Teacher’s Service Commission performance when combined with other research variables, the management is not making the best possible use of the HRIS data supply in order to make appraisal decisions. These aspects of e-payroll were not investigated in this study. Therefore, in order for TSC to properly administer their e-payrolls, they need to identify the various components of e-payroll and incorporate those components into their information systems for managing human resources.

Published: June 2024

This study addresses the need for lightweight, wear-resistant aluminium alloys in the automotive industry to combat climate change. Here, aluminum composites reinforced with various combinations of silicon carbide (SiC) and aluminum oxide (Al2O3) were fabricated from recycled aluminum cans using stir-casting. Wear resistance, thermal conductivity, and frictional power loss were evaluated. The serial tests of frictional power loss, thermal conductivity, and wear resistance results on PA, CS, 4% SiC-2%AO, 4% SiC-4%AO, 4% SiC-6%AO, 4% SiC-10%AO, and 6% RHA/4% PSA samples are the following: 1000, 1000, 850, 750, 550, 450, and 550 watts; 270, 260, 220, 200, 180, 125, 185, and W/m-K; and 0.24, 0.18, 0.3, 0.23, 0.12, 0.06, and 0.24 mg, respectively. The 4%SiC/10%Al2O3 composite demonstrated superior wear resistance against plastic deformation, minimal frictional power loss, and the highest thermal conductivity among the tested samples. This improvement is attributed to a wear-reacted layer formed during testing. Interestingly, the 4%RHA/6%PSA composite, utilizing alternative reinforcements, offered comparable thermal conductivity to other SiC/Al2O3 combinations, suggesting potential for further exploration. This research promotes the use of recycled materials while achieving the desired properties for sustainable automotive applications

Published: June 2024

The environment is sustainable if it is free of air, water, and soil pollution. This agrees with the United Nations Sustainable Development Goal Three (SDG3). However, urbanization and industrialization have aggravated the rise of air pollution which are hazardous to both human health and society. Ingestion of large quantities of air pollution gases is one of the greatest health risks in the environment which often leads to death, brain damage, and loss of consciousness at high doses. Some common sources of carbon monoxide (CO), the most severe of these gases, can be traced to the incomplete combustion of cars’ fuel, malfunctioning equipment, clogged chimneys and vents, and interior use of portable generators. Traditional ways of monitoring pollution are laborious and involve inefficient processes. To address this challenge, this paper implemented a real-time Air Quality Monitoring System using the Internet of Things (IoT) to measure the concentration of CO. The IoT devices were used to collate data within specific areas. The data collected, by the sensor, were processed using software which is then trained in the system to predict air pollution levels based on historical data. The system also includes a user interface that allows users to view real-time air pollution data and receive alerts when pollution levels exceed the safe threshold. The system was tested in different environments, Air Force Institute of Technology and Kawo; densely populated areas of Kaduna State, Nigeria. This was done to demonstrate the high level of accuracy and reliability of the system. The correct implementation of the developed system has the potential to be used as a tool for researchers, and for the general public to better understand and address the problem of air pollution.

Published: June 2024

This study aimed to investigate the influence of mono ammonium phosphate (MAP) on ash yield from the co-combustion of sugarcane bagasse and banana leaves in a muffle furnace. An I-Optimal design of the Combined Methodology, embedded in Design Expert (version 13.0.5), was employed to optimize ash yield, considering various particle sizes, additive concentrations, and temperatures. The mixed samples were ashed in a muffle furnace to a constant weight, and the ash yield was analyzed using statistical tools to assess the model's quality. The MAP additive was most effective at concentrations between 4% and 7%, beyond which ash yields increased significantly. The optimal composition was determined to be 75% sugarcane bagasse, 20% banana leaves, and 5% ammonium phosphate at 950°C, resulting in the lowest ash yield of 6.46%. The presence of MAP in the biomass mixture significantly reduced ash yield. The model's R² and adjusted R² values were 0.9825 and 0.9099, respectively, indicating accurate determination of the model coefficients. This study demonstrates that ammonium phosphate additive has great potential in mitigating ash-related problems in biomass combustion.

Authors: Adegbola A. A , Abioye A. I. , Yakub Y. O .
Published: June 2024

Unsaturated zone is of great importance in providing water and nutrients that are vital to the biosphere and often the main factor controlling water movement from the land surface to the aquifer. Steam injection for remediation of porous media contaminated by NAPLs has been shown to be a potentially efficient technology. However, the need for its improvement in recovery efficiency using other methods has been a subject of continuous study. The aim of this study was to carry out the experiments to investigate the effect of magnetic field on the removal of NAPLs from unsaturated zone using Steam Injection An unsaturated zone of a sand box of interior dimensions 110 x 74 x 8.5 cm was polluted at different period with 200 mL of Toluene. Steam injection experiment with flow rate of 0.01 m3/s was performed to determine the recovery efficiencies of Toluene only in an unsaturated zone containing sand of porosity 0.42 and permeability of 0.001163779 cm/s with the introduction of varying magnetic field 1-3T in step of 1T. The results for the recovery efficiency of Toluene using steam injection only was 80.30% while that of steam injection and magnetic field at 1-3 T yielded 83.70-86.60 %. The results of recovery efficiency of steam injection with magnetic field were 4.23-7.85 % higher than the result of steam injection only for LNAPL (Toluene). A combined application of steam injection with magnetic field appreciably enhances the removal of Non Aqueous phase liquids from Unsaturated Zone.

Authors: Oyesola L. A , Adejumo A. L, , Jimoh M.O. , Solomon B.O .
Published: June 2024

Snail farming being a low cost farming process that requires minimal professional skill requirements has gained more attention in recent times. Snail meats are rich in protein but are vulnerable to microbial contamination due to their habitat. Smoking and drying are the most common method of preserving snail meat in Africa, especially Nigeria. The quest to retain the nutritional value of snail meat while preserving it fresh has necessitated further investigation. Fresh snail meats were preserved by canning in three packaging media (brine, vinegar, brine-vinegar). The effects of canning time, temperature, nitrite concentration and packaging media on protein content, fat content, moisture content, ash and pH were investigated using Taguchi model. Statistical analysis was carried out. Process parameters were also optimized and validated for effective snail meat canning. Temperature was discovered to be the most controlling parameter for the variation in protein, fat and moisture content. Carbohydrate and ash content were not significantly affected by the process parameters. The optimum canning process parameters, 50 mins, 121℃, brine and 100 ppm sodium nitrite concentration gave 18.98% ±0.11 protein content, 1.51% ±0.09 ash content, 1.40% ±0.04 fat content, 1.88% ±0.13 carbohydrate content, 76.23% ±0.08 moisture content and pH of 5.93 ±0.06. The absence of heterotrophic bacteria, fungi, coliform and Staphylococci in the validation experiment confirmed the efficiency of the optimum conditions and its suitability in the commercial preservation of canned fresh snail meat.
The Corrosion inhibitory performance of hybridized rice-husk extract and biopolymer waste on food-compatible mild steel in acidic media
Authors: Adeoye B. K.
Published: June 2024

Metal corrosion is frequently the outcome of the reactive interaction between food's corrosive components and metal alloy during processing and packaging. This study used gravimetric and depth of attack methodologies to examine performance of hybridized rice husk extract and chitosan, as a corrosion inhibitor for mild steel in 1 M HCl. Rice husk was subjected to phytochemical screening in order to choose the best material combination. Gas chromatography–mass spectrometry was then used to characterize the extract. Fourier transform infrared spectroscopy was used to characterize the corrosion film solution and chitosan synthesized from residual biopolymer fish scale. The rate at which the coupon corroded with and without rice husk extract and chitosan was assessed in relation to temperature, concentration, and time. The formation of a film over the metal surface was facilitated by the presence of polycyclic chemicals, tannins, and cellulose, thus aiding corrosion. Inhibition efficiency increased with increase in temperature and concentration of rice husk extract. Kinetic parameters showed that Langmuir isotherm is the best fit because the R2 value is close to unity. The addition of 5:1 ratio of rice husk to chitosan shows a great difference as the inhibition efficiency increase with increasing temperature to 80% inhibition efficiency

Published: June 2024

Output performances such as induced-voltage and torque of an electric machine are investigated in this study, with particular reference to its pole number effects. The analyses are made using 2D-finite element method. The study revealed that the investigated machine having 6 stator slots and 11 pole number i.e. 6S/11P has the highest amount of magnetic remanence, coercive force and flux linkage amongst the compared machine types. Consequently, these highest values would yield the largest output torque in the machine. Desirably, high output torque is also relatively realized in the 6S/13P machine type. Nevertheless, both the 6S/11P and 6S/13P machine types would be adversely affected by large effect of magnetic force on its rotor. The greatest field-weakening ability, determined as a measure of the machine’s speed ratio is provided by 6S/13P machine topology and this trait is desired in traction and propulsion systems. The most competitive torque is also obtained from 6S/13P machine, considering its yield with respect to the employed magnet volume.

Because human activity is constantly increasing the content of heavy metals, heavy metal removal becomes a major challenge in wastewater treatment. In an attempt to provide an innovative and sustainable option for addressing the said challenge, this study is aimed at the synthesis and characterization of nano-based CaO biosorbent from oyster shell. The sol- gel method was used to synthesize the biosorbent, characterized using FTIR, XRD, SEM and BET respectively. From the analysis conducted, the developed CaO nanoadsorbent has a point of zero charge of 5.6, indicating stable charge balance. The biosorbent was chemically characterized by the presence of a number of functional groups, most notably the –OH and C-H. The CaO nanoadsorbent was found to be crystalline in nature as revealed by XRD analysis. Findings from the BET indicated the material has a surface area of 344.528 m2/g, specific pore volume of 0.170cc/g and pore diameter of 2.118nm, indicating that it is mesoporous structurally. The results of the characterization reveal that the CaO nanoadsorbent present a suitable option for treatment of wastewater based on its associated attributes.
Decreti delegati and student movement in the 1970s
Authors: Rosso Lanfranco
Published: June 2024

The article investigates the effects of the long Sixty-Eight on Italian schools from the perspective of participation and school policies. By interweaving educational-historical research with research on social conflict, it aims to restore the Decreti delegati to the history of the 1970s, inserting them into the tortuous process of democratization of educational institutions that began in 1968-69. Comparing institutional sources with those produced by the movements restores to us the ambivalent relationship between contestation in secondary education and the ’74 measures. The reform seriously challenged the student movement, which was divided over the choice between participation and boycotting the elections. In February ’75, however, the students poured the ideal carryover of Sixty-Eight into the ballot box. Indeed, the issue of school democracy had its roots there. In the late 1970s, the movements, with their anti-institutional charge, seemed to reject the representative mechanism as collegial management entered a crisis and showed all its limitations.
The school in the 70s between history and historiography. From “molecular reforms” to the birth of a “new educational culture”
Authors: Gabusi Daria
Published: June 2024

The contribution traces the school policy of the 1970s, with a particular focus on the measures that made that phase an “irreversible caesura” in the history of Italian school. On the one hand, reference is made to the legislative measures that represent a significant response of the political system to the new needs of school and society posed by the student and youth protests of 1968. On the other, divergent historiographical interpretations are compared: the critical gaze of those who have been able to grasp only the negative elements (“destructive reformism”), and the analysis of those who, without concealing limitations and shadows, valued that decade as a “fruitful period”, not least for the resilience of the democratic framework. The “micro-reforms” innervated a “molecular reformism” that helped renew school and educational culture: less reactionary and classist, more emancipatory and inclusive.
Struggle and health. Sociability and literacy in the “150 hours” courses in Turin
Authors: Bianchini Paolo , Pongiluppi Francesco
Published: June 2024

Throughout the years of the reforms, Turin’s political and trade union organizations succeeded in collecting and combining the requests coming from people’s workplace and everyday’s life to develop new models of social governance of schools and social services. All this was realized by reversing the responses given to social discomfort and suffering through a re-appropriation of spaces and a growing participation of citizens in all the social choices. This contribution aims at reconstructing the initiatives and experience of the courses of the so-called “150 hours school” in the years 1974-1978: in this period, the training on prevention on women’s health was carried out in middle schools and in university seminars, and it was open to male and female workers. These training started a process of awareness, active citizenship and representation that – from the collegial bodies of the schools to the newly born local councils, up to the factory councils – brought into question and “in motion” parents, school staff and new residents and workers.
The catholic society facing the delegated decrees
Authors: Dessardo Andrea
Published: June 2024

The law 477/1973 was approved in a moment in which the Italian catholic society was facing a hard inner crisis, emerged in the post-Council season: the Catholic Action, the Italian catholic laity biggest aggregation, suffered a drastic drop in affiliations and its choice to give up the political side mobilisation was subject of incomprehensions and conflicts, that divided catholic people into tendencies, both expressions of different ways to live their faith witness and of different political positions. The collegial boards elections made evident these cleavages also in school.

Decree 419/74, which regulated school experimentation, is perhaps the least known of the delegated decrees on schools. Yet, for twenty years it was the only measure with which to try to renew high school in the absence of a reform, until the advent of school autonomy. The decree reflected the international debate on the comprehensive school and the regionalization process then underway in Italy, but also the need for the Ministry of public education and its administrative apparatus to govern a “periphery” in disorder. It therefore represents a governance tool with which teachers, local and regional agencies and the ministry itself have attempted to find a new balance in the relationship between school and territory. The protagonists of this sort of ante litteram school autonomy were the “minisperimentazioni” and “maxisperimentazioni” launched through article 3 of the decree. Heirs of the “bienni unitari” of the Seventies, they tried to change the school structure to try to respond to the social transformations of the country first during the Seventies, and then in the Eighties, at a time marked by the progressive loss of the centrality of the school in the within an increasingly broad and crowded formal and informal educational landscape.
School cultural heritage between history and memory: insights into the historical-educational heritage and communication strategies of the Museo de la Educación de la Universidad del País Vasco (Spain)
Authors: Lucchetti Costanza
Published: June 2024

New impulses in the field of history of education, starting with the development of the strand of studies relating to the so-called material culture of schools and the widespread interest in the cultural heritage of schools, as well as the contaminations determined by the blossoming of the new museology, have led to an important development of school and education museums in recent decades. The origins of this particular type of museum can be of the most varied. Some come into being as a result of important university projects and on the basis of accurate historical-educational reconstructions. This is the case of the Museo de la Educación de la Universidad de País Vasco (Meupv), which is presented here. The Spanish museum has its own very specific peculiarity, both in terms of its ability to promote a continuous development of studies in the field, with solid anchorage in the local history of education, and in terms of its ability to address a diversified and therefore also non-specialist public by drawing on multiple channels of communication, according to the recent perspective of the public history of education.

Innovation, homologation, regimentation. The multiple perspectives of the Delegated decrees
Authors: Causarano Pietro , Martinelli Chiara
Published: June 2024

In 1974, the so-called “Decreti Delegati” occurred after years of ministerial documents and experimentations whose success depended on headmasters’ and teachers’ leanings; they put into action parts of suggestions and predictions made during the first years of 1970s. Indeed, they modified the way scholastic organisation runs, they de-verticalized it to some extent and established connections among school, society and territory on an institutional basis. This constitutes a topic that has been highly debated in the domain of educational sciences, as are the frantic and complex social events occurred after 1968.
Analysis of Total Microcystins using LC-MS/MS: Assessment of Pretreatment Technique for MMPB(2-methyl-3-methoxy-4-phenylbutyric acid)
Authors: Kim Min-Jeong , Choi Jae-Won
Published: June 2024

Algal toxin analysis, particularly for microcystin (MC) variants, is commonly performed using LC-MS/MS as the standard method. In 2016, the environmental protection agency (EPA) published method 546 for the determination of total MCs by ELISA. However, the limited availability of commercial algal toxin standards limits the efficacy of the LC-MS/MS method. This study proposes a novel approach using the 2-methyl-3-methoxy-4-phenylbutyric acid (MMPB) structure generated by oxidizing MCs with potassium permanganate and sodium periodate. MMPB is formed through the oxidation of the common (all-S,all-E)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyldeca-4,6-dienoic acid (ADDA) structure, eliminating the need for specific standard materials for each MC variant. This provides a method for measuring the total MCs. This study focused on optimizing sample pretreatment before oxidation, salt removal as a post-oxidation step, and the quantitative method to establish a comprehensive total MC detection approach applicable to surface water samples. The whole process included pretreatment using a freeze-drying method, purification using liquid-liquid extraction (LLE) for salt removal, and a comparison of quantitative methods using internal standards. Additionally, an evaluation of internal standards was conducted to assess availability during the oxidation process. In this study, an MMPB recovery rate of up to 50% was achieved, with an analysis precision of 14%. According to the results of QAQC, the satisfactory linearity of the calibration curve was a precision and the performance of the method for spiked samples was verified. The MMPB analysis method developed in this study showed relatively lower quantification limits and recovery rates than individual MC analysis methods. We believe these results stem from the inherent sensitivity differences between MCs and MMPB, as well as the complexity of the pre-treatment process centered around the oxidation process.

Analisis Yuridis Tentang Tanggung Jawab Pidana Atas Kematian Atlet Tinju dalam Pertandingan
Authors: Lookman Wiraatmaja
Published: June 2024

Penelitian ini bertujuan untuk melihat apakah kematian atlet tinju memiliki akibat hukum bagi atlet lawannya ditinjau dari peraturan-peraturan perundang-undangan yang ada dan siapa sajakah yang dapat bertanggung jawab jika terjadi kematian atlet tinju di dalam pertandingan. Pada tahun 1967, PERTINA resmi masuk sebagai anggota KONI sama halnya dengan induk organisasi lain melalui pengukuhan Keputusan Presiden No. 57 tahun 1967, sehingga tinju sejak saat itu dianggap sebagai cabang olahraga dan pasal 182 sampai dengan pasal 186 KUHP tentang perkelahian tanding tidak dapat diterapkan pada tinju, undang-undang yang berlaku bagi tinju adalah Undang-undang no. 11 tahun 2022 tentang keolahragaan (UU Keolahragaan). Pasal 103 UU Keolahragaan tidak mengenal pidana terhadap atlet sehingga kematian atlet dalam pertandingan tidak memiliki akibat hukum bagi lawannya, namun pasal 103 ayat 1 UU Keolahragaan mengancam pidana bagi penyelenggara yang tidak memenuhi ketentuan pasal 52 UU Keolahragaan. Dunia olahraga mengenal prinsip Lex sportiva yang dapat dijelaskan sebagai hukum khusus yang mengatur tentang olahraga yang dibuat oleh institusi olahraga itu sendiri yang berlaku serta ditegakkan oleh dan untuk lembaga olahraga itu sendiri tanpa intervensi dari hukum positif suatu negara maupun hukum internasional. Pasal 61 dan pasal 102 ayat 5 UU Keolahragaan mengakui secara eksplisit prinsip ini dan konsekuensi dari pengakuan statuta cabang olahraga di dalam UU Keolahragaan menjadikan statuta cabang olahraga tinju (statuta IBA) menjadi lex spesialis bagi UU Keolahragaan. Pelanggaran penyelenggara pada pasal 103 ayat 1 UU Keolahragaan juga diatur dalam pasal 9 juncto pasal 26 juncto pasal 32 kode etik IBA sehingga dalam hal ini pasal 103 ayat 1 juncto pasal 52 UU Keolahragaan tidak dapat diterapkan pada penyelenggara dalam hal terjadi kematian atlet dalam pertandingan.
