The global COVID-19 vaccination had an undeniable influence on the pandemic management, despite of having reported rare but life-threatening side-effects of vaccines. Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare autoimmune complication determined by thrombocytopenia and thrombosis propensity in the circulatory system. The activation of antibodies against platelet factor-4 (PF-4) which mimics the heparin-induced thrombocytopenia (HIT) characteristic is the main known pathogenicity of the disease. Herein, we reported a case of VITT in a middle-aged woman with no previous history of thrombophilia or other medical conditions who presented with thrombosis of the left superficial femoral artery 3-days after receiving the second dose of inactivated BBIBP-CorV (Sinopharm) vaccine. The patient underwent bypass vascular surgery and received none-heparin anticoagulation consistent with high-dose intravenous immunoglobin. Eight days after the discharge, she was subsequently referred to our center with the presentation of sub-massive pulmonary thromboembolism in spite of receiving the prophylactic anticoagulants during follow-up period. Details on side-effects of COVID-19 vaccines, specifically the inactivated ones are yet to be fully ascertained. Clinicians should consider the history of COVID-19 vaccines in thromboembolism patients who do not have well-acknowledged risk factors. Further studies about the necessity of prophylactic anticoagulants and clinical judgment for receiving other vaccines in such patients are required.

Drug induced erythema multiforme (EM) is a rare clinical entity which majorly involves the oral cavity. It commonly occurs due to intake of drugs such as NSAID’S, certain antibiotics, and anticonvulsants. It is characterized by rapidly rupturing vesicles leading to ill-defined erosions in the oral cavity and encrusted lip lesions. These lesions are usually difficult to differentiate from other vesiculo bullous and ulcerative lesions which would have a similar presentation and the absence of skin lesions can sometimes lead to misdiagnosis. Drug induced EM has an acute onset and is a self-limiting inflammatory hypersensitivity reaction that causes blistering and ulcerations of the skin and mucous membrane. The lesions heal following the discontinuation of the causative medications. This case report describes a case of drug induced Erythema multiforme of the oral cavity that occurred consequent to the intake of Tab.Diclofenac Sodium and Tab.Cephelexin. The patient developed painful, bleeding, burning ulcerations with severe crustations on the upper, and lower lip, lateral and ventral surface of tongue, hard palate and retro molar regions. The case was managed with corticosteroids.
Planned behaviour, gender, and attitudes towards entrepreneurship among business economics and electrical engineering students
Authors: Ognjenovic Kosovka
Published: December 2022

This paper examines entrepreneurial intentions in the context of life course transitions among undergraduate students enrolled in the economics and electrical engineer?ing faculties of the University of Belgrade. The entrepre?neurial intention model is built upon the theory of planned behaviour, examining the associations between students? willingness to become an entrepreneur, their attitudes and perceptions about the importance of subjective norms, and perceived behavioural control variables. The data comes from a self-administered survey. The results show that attitudes towards entrepreneurship and behavioural control factors form positive and statistically significant associations with students? future entrepreneurial orien?tation, while subjective norms and risk-willingness add a little explanatory power to the initial regression models. In order to better understand the initial stage of life course transitions among the students, single regressions are estimated. All the factors appear as statistically significant with meaningful coefficient values, further showing that entrepreneurial prediction is highly gendered and depends on what faculty the student attends. This paper reveals for policy practitioners the main characteristics of young en?trepreneurs-to-be and their understanding of the process of creating a business venture.

Background

While the deleterious effects of trans fatty acids -TFAs- on cardiovascular health are well established, their impact on type 2 diabetes remains poorly understood. In particular, little is known on the impact of specific TFA types on type 2 diabetes etiology.

Objectives

To explore the associations between different types of TFAs (total, ruminant, industry-produced and corresponding specific isomers) and risk of type 2 diabetes. 

Research Design and Methods

105,551 participants aged ≥18y from the French NutriNet-Santé cohort (2009-2021) were included (mean baseline age=42.7y (SD=14.6y), 79.2% women). Dietary intake data, including usual TFA intake, were collected using repeated 24-hour dietary records (n= 5.7 [SD=3.1]). Associations between sex-specific quartiles of dietary TFAs and diabetes risk were assessed using multivariable Cox models. 

Results

Total TFAs was associated with higher type 2 diabetes risk (HRquartile 4vs.1=1.38; 95% CI=1.11-1.73; Ptrend<0.001, 969 incident cases). This association, specifically observed for industry-produced TFAs (HR=1.45; 95% CI=1.15-1.83; Ptrend<0.001), was mainly driven by elaidic acid (HR=1.37; 95% CI=1.09-1.72; Ptrend<0.001) and linolelaidic acid (HR=1.29; 95% CI=1.04-1.58; Ptrend=0.07). In contrast, ruminant trans fatty acids were not significantly associated with risk of type 2 diabetes.

Conclusions

In this large prospective cohort, higher intakes of total and industry-produced TFAs were associated with increased type 2 diabetes risk. These findings support WHO’s recommendation to eliminate industry-produced TFAs from the food supply worldwide. Consumers should be advised to limit the consumption of food products containing partially hydrogenated oils (main vector of iTFAs). This may contribute to lower the substantial global burden of type 2 diabetes.

Published: December 2022

A vacuum selective laser melting method with a beam profile control was developed to fabricate the high quality 3D object. To investigate the quality of 3D fabrication, the denudation zone (DZ) as a quality indicator was evaluated to make a single bead. The main challenge is to clarify the correlation between the DZ and beam profiles. The beam profiles, such as a Gaussian mode, a doughnut mode, and a flat-top mode, were formed in several modes, by a dioptric system with a beam shaper. A stainless steel 316L (SS316L) powder was irradiated in arbitrary pressure to form a single bead, and then the DZ was measured. As a result, it was found that the flat-top mode recorded the minimum value of the DZ under atmospheric pressure. Thus, the dynamics of the metal vapor while the laser irradiation were observed by the Schlieren imaging technique under atmospheric pressure. The average velocity of metal vapor with flat-top mode was the slowest, i.e., 0.199 m/s. It was found that the DZ becomes small depending on the dynamics of metal vapor. The ambient pressure was reduced to 300 Pa in order to reduce the gas movement, and the DZ with flat-top mode was improved to record a minimum value of 0.048 mm, 1/3 of the DZ at atmospheric pressure.

Clinical Manifestations of Benign Paroxysmal Positional Vertigo of the Horizontal Semicircular Canal: Pathophysiology of Atypical Manifestations
Authors: Amor-Dorado Juan Carlos
Published: December 2022

The presence of a direction changing positional nystagmus (DCPN) in a patient with vertigo is the characteristic sign to diagnose a benign paroxysmal positional vertigo of the horizontal semicircular canal (HSC-BPPV). If a persistent DCPN is observed when positional tests are performed, a light or heavy cupula phenomenon must be suspected. In order to differentiate between these clinical phenomena, a null plane test should be considered for diagnosis. On the other hand, when a paralytic or irritative fixed direction nystagmus is found, then a complete or incomplete jamming within the HSC may be involved. In this particular situation a head shaking nystagmus test may be clarifying. When persitent DCPN or paralytic-irritative nystagmus are found in positional testing, ENT clinicians must keep alert to search for atypical clinical forms of HSC-BPPV.

Published: December 2022

Após uma breve apresentação da posição de Karl Marx sobre o comércio internacional, discutimos a evolução da balança comercial sino-americana, segundo a qual os Estados Unidos aparentemente estão perdendo. A seguir, propomos dois métodos de mensuração do intercâmbio desigual entre esses países, um considerando o conteúdo de trabalho diretamente incorporado nas mercadorias trocadas, e outro centrado no valor internacional delas, utilizando tabelas de entrada e saída, que mostram que os Estados Unidos realmente vencem. Uma análise setorial indica uma erosão da vantagem dos EUA, ou seja, que eles ganham no intercâmbio, mas cada vez menos. Por fim, examinamos o desafio à hegemonia global para apreender o que os Estados Unidos têm a oferecer ao mundo.
Consideraciones sobre la situación financiera de la previsión social argentina
Authors: Carpenter Sergio
Published: December 2022

La situación financiera de los sistemas previsionales es motivo de preocupación en el debate público, tanto en lo referido a sus impactos en el largo plazo, dada la evolución esperada de las variables demográficas, como en los análisis de la evolución macroeconómica en el presente, dada la envergadura que observa el gasto previsional. Así, el presente trabajo examina la trayectoria de recursos y gastos vinculados a la previsión social, así como los elementos contextuales que permiten caracterizar su situación financiera. En ese recorrido, se tiene que el sistema previsional argentino expresa numerosas tensiones e inequidades, aun en una situación en donde se ha alcanzado una cobertura pasiva prácticamente universal. En los últimos 5 años, se ha profundizado la diferencia entre los recursos afectados a su financiamiento y su gasto, en un contexto de estancamiento o reducción de la producción material y deterioro de los salarios reales. Asimismo, se determinan y analizan diversos resultados económico financieros asociados a la frondosa heterogeneidad de prestaciones y programas existentes, lo que ayuda a identificar posibilidades de intervención en función de reducir inequidades.
O conteúdo da crise cíclica de superprodução de capital
Authors: Nogueira Rodrigues dos Santos Thiago José
Published: December 2022

O fenômeno das crises é recorrente no capitalismo. Dentre as escolas da teoria econômica, a teoria marxista influencia o estudo das crises, porque identifica que as crises são internas ao modo de produção capitalista. O objetivo do trabalho é analisar o conteúdo da crise cíclica de superprodução de capital. A abordagem do trabalho é fundamentada na crítica da economia política de Karl Marx. O desenvolvimento do trabalho consiste na análise de um modelo teórico abstrato que permita compreender o germe da crise e o seu desenvolvimento à possibilidade de crise. Trata-se também de analisar a crise cíclica de produção de capital em duas passagens teóricas cumulativas. A primeira aborda o caráter da crise de superprodução, enquanto a segunda evidencia o aspecto cíclico da crise no capitalismo. Conclui-se que a associação da lei geral de acumulação do capital com a trajetória cíclica da economia, nos permite uma interpretação do conteúdo da crise cíclica de superprodução inserida na dinâmica do modo de produção capitalista.
semente do Protestantismo
Authors: Gazolli Junior Geraldo Moyses
Published: December 2022

O presente artigo é uma reflexão e análise bibliográfica sobre as disparidades e motivadores da movimentação migratória protestante na Europa e América. A América Latina possui uma identidade particular pouco conhecida concernente aos motivadores de seus pioneiros, se por um lado a história retrata o desejo por um reavivamento religioso dos recém-chegados à América do Norte, do outro lado a imigração latina buscou liberdade religiosa de toda forma de autoridade por influência dos ideais regionais. Muitos grupos protestantes se isolaram em comunidades rurais formando uma cultura protestante singular que mais tarde, foi um desafio para o alcance da autoridade europeia religiosa. As estruturas de pensamento formadas pela regionalização do protestantismo informam a busca de uma identidade pautada para atender aos anseios de uma realidade não atendida em terras europeias.

The article considers the possibility of reducing the man-made load on surface and ground waters in Lysychansk-Severodonetsk industrial agglomeration caused by numerous sludge collectors and tailings storage facilities of various industries formed many decades ago. The paper provides information on the location and technical condition of the sludge collectors of the liquidated "LYSSODA" manufacture (Luhansk oblast), the amount of waste currently stored in them as well as the impact of these wastes on the quality of groundwater in the area where the sludge collectors are located. The work shows one of several possible options for using such wastes as a valuable secondary mineral raw material for obtaining a marketable product. The averaged data on the chemical composition of the solid phase of sludge and indicators of the liquid phase composition are given. According to the results of the analysis of scientific and technical information, it has been found that such wastes can ultimately be used for the production of anti-icing reagents. The obtained results of research on the dependence of the freezing point of working solutions on the concentration of salts, including the added corrosion inhibitors (triethanolamine, hexamethylenetetramine), indicate the feasibility of using soda ash production waste to obtain effective liquid anti-icing reagents without a mechanical component, while the optimal amount of added corrosion inhibitors is 0.5% wt. Such reagents can be used both undiluted at temperatures up to minus 20oC and strengthened to 15-20% wt. by calcium chloride at temperatures up to minus 40°C with consumption on highways at the level of about 100 g/m2 of the treated surface.

This study narrates environmental quality of residential areas in Lagos Metropolis, Nigeria with a view to evolving policy response for planning and development of livable environment and others with similar characteristics. This narration is in terms of the environmental characteristics of the residential areas, the level of importance that the residents attached to the environmental characteristics and the level of satisfaction that they derived from them. The study made use of data collected from three hundred and twenty-one (321) residents systematically sampled across the three residential density areas (high-density, medium-density and low-density) of Lagos Metropolis. Data analysis was done using cross-tabulations and analysis of variance. Findings revealed that environmental quality in the metropolis was at the low ebb, especially in high and medium density areas. Residents attached high level of importance to environmental characteristics of the study area but derived low level of satisfaction from the environmental characteristics. Based on the study, it was recommended that there is need to put in place a workable legal framework to boost the condition of environment across the residential density areas of the metropolis. Also, through public enlightenments, and awareness, residents should ensure judicious use of the environmental amenities and be environmentally-friendly in their utilization.

Published: December 2022

The article discusses the essence and concept of sustainable development, the results of the agro-ecological assessment of the given territorial community lands, and determines the indicators of the goals of sustainable development that can be used in the local territories. The author has worked on scientific materials in Ukrainian and international professional publications and outlined the prospects for further scientific research in this direction. The general scientific, ecological, sociological, and mathematical research methods are used in the work. A brief analysis of indicator systems for forecasting the state of the environment is provided using the example of the settlement of Velyka Snitynka. It was established that the excess content of heavy metals in the soil is mainly related to the incorrect use of mineral fertilizers. It has been investigated that the assessment of the ecological state of water bodies in rural areas is an important indicator for the development of a strategy for sustainable development: the main contribution to water pollution is made by anthropogenic sources, in particular, the livestock complex and domestic manure storages and dumps. It was determined that the air quality index is a relevant indicator: exceeding the average daily concentration of fine dust indicates the need to develop programs for local monitoring of the atmospheric air.

The waste of foundries of machine-building plants - spent moulding mixtures was studied. The expediency of using spent mixtures of foundry production as a siliceous component of foam concrete mixtures has been proven. The spent mixtures were studied for their foaming ability. The foam properties are determined. The effect of concrete mixture components on the pore-forming ability of foam agents was investigated. Of the six foaming agents studied in the work, saponified tree resin was found to be the most effective. The technological parameters for the preparation of aerated concrete mixture have been developed. The average density of foam concrete in the dry state and its limit of compressive strength were used as criteria for resource evaluation of used moulding mixtures of foundry production. Foam concrete products of non- autoclave hardening with an average density of not less than 900 kg/ m 3 and a compressive strength of not less than 4.5 MPa were obtained.

The state of seed self-regeneration of woody plants of Kyrylivka Park (Dnipro, Ukraine) in areas with a strong, moderate and non-existent level of recreational load was studied. Floristic methods (estimates of species richness, determination of floristic community and homogeneity), methods of ecological analysis of vegetation, physico-chemical methods of soil analysis, statistical methods are applied. It was established for the first time that in Kyrylivka Park, artificial stands are capable of forming a sufficient amount of viable undergrowth of autochthonous (53,5%) and introduced (46,5%) species. The amount of tree growth of adventitious plants in the areas according to the level of recreational load is distributed as follows: with no load – 32,2% of the number of self-regenerating trees, with moderate – 41,3%, with strong – 89,7%. The indices of species richness of Margalef and Menkhinik of self-regenerating tree species for the site with a strong recreational load turned out to be the largest (at the expense of adventitious species) compared to the sites with a moderate recreational load and without it. The calculated Koch index of biotic dispersion (40.0%) indicates a certain process of floristic homogenization of the tree stand in the investigated territory of the park. The correlation coefficients between the number of self-restored allochthonous and autochthonous tree species for the studied areas with strong, moderate and absent recreational loads are significant (0.90, 0.92 and 0.88 respectively). The need to analyze and forecast the possible remote consequences of the introduction of alien species in the composition of the dendroflora is emphasized.

Advances in molecular biology tools have made it possible to make progress in terms of therapeutics by acting specifically on the molecular mechanisms involved in the virulence of pathogens or in the development of the disease. In the case of cancer, new therapeutics have been developed thanks to these advances. This is called targeted therapy. Targeted therapy molecules specifically act as a molecule, or a molecular pathway involved in the development of the tumor. The use of targeted therapy drugs therefore requires molecular characterization of tumors. In developing countries, the reference tool is high-throughput sequencing, but due to the high cost, this strategy remains inaccessible for the majority of African populations. It is remains necessary to implement alternative molecular diagnostic tools in order to reduce the disparities currently observed in access to cancer care. The High-Resolution Melting analysis (HRM) method is based on real-time PCR and is described as a simple, rapid and specific method for the detection of somatic mutations predictive of anti-tumor therapeutic response. We demonstrated in this study that this method could be implemented in a lower middle-income country like Côte d’Ivoire, and we used it to detect KRAS mutations in colorectal cancer patients for the first time in Cote d’Ivoire.
Analytical Procedure for Determination of Lead in Blood and Urine by Atomic Absorption Spectrometry
Authors: Mohammed Abdul Moiz
Published: December 2022

Lead is one of the natural constituents of earth found in soils, plants, and water. Lead predominantly a concern for neurological toxic effect particularly in children due to its irreversible neurological damage. The common spectroscopic methods in trace element analysis in biological fluids are dithizone extraction, polarography, spectral analysis, atomic absorption spectrometry (AAS), inductively coupled plasma atomic emission spectrometry. A graphite furnace atomic absorption spectrophotometer is a valuable, simpler, and cost-effective spectrometric technique for the identification of lead absorbance in the human system. The GF-AAS method can be employed for the measurement of lead percentage in whole blood and urine, and the results acquired are helpful in biological monitoring and clinical diagnostic of work related to surrounding lead exposure. The paper reports the average lead concentration, and calibration graphs for standards as well as absorbance against lead concentration, which will be productive in future for analytical determination of lead in blood and urine.
Global Health Policies and International Cooperation in the Middle East and North Africa (MENA)
Authors: Vlaikidi Elpida
Published: December 2022

The core belief behind global health is that “disease knows no borders” and thus, in order to eliminate health risks, we should focus on the scope of their problems and not their location. However, some countries, such as those located in the Middle East and North Africa, which are dealing with economic and political instability as well as conflict, have to face greater health challenges than others. These states tend to depend more on international cooperation and global health policies to eliminate the growing health challenges in their region. This paper seeks to examine the general health status, health risks as well as some global and regional health initiatives implemented in the MENA region, aiming to respond to the multitude of health issues affecting these countries.
Opinion Leaders versus Interpersonal Forces: Analysis of the Relative Influence on Zimbabwean Farmers Input Purchase Behavior
Authors: Nyamhamba Talent , Odunze Daisy Ifeoma
Published: December 2022

This study had the primary aim of analyzing the relative influence of opinion leaders and interpersonal forces on farmers’ input purchases. The interpersonal factors analyzed in the study include age, education, income, years of farming experience, farm size, and family/friends while the opinion sources investigated include input supplier/distributors, extension agents, other farmers, cooperative leaders, and internet search. The study also had the secondary objective of determining the most influencing interpersonal factor and the most influencing opinion source on farmers’ input purchases decision. The study employed the use of the descriptive research design and quantitative research methods in data collection and analysis. Data was collected through a survey of 100 farmers in Bulawayo Metropolitan province of Zimbabwe using the convenience sampling technique. Findings indicate that interpersonal forces have more influence on farmers’ input purchase decisions than opinion leaders. Findings also indicate that farmers’ farming experience is the most influencing interpersonal factor in this study while other farmers’ opinions are the most influencing opinion source. Other farmers’ opinions are also based on their own experience; therefore, experience is the crucial factor influencing input purchase decisions. The implications of this finding on practice are that farmers are inclined to reject new inputs they and other farmers have no experience with and it is therefore recommended that both extension agents and input suppliers develop strong partnerships with farmers to influence the adoption of new inputs.

Authors: Simons Lori , Schoneman Sara , Blank Nancy
Published: December 2022

A total of 306 students participated in a practicum/internship (P/I) program. Retention and employment outcomes suggest that students are likely to continue at the university after being exposed to career issues in beginning psychology courses and they are likely to obtain employment in ending psychology courses. Students also made improvements in their racial-cultural identity development, racial, cultural, and social justice attitudes, and problem-solving, civic responsibility, and community engagement skills from the beginning to the end of the program. Sixty-eight percent of students evaluated the course as challenging and 54% of them felt prepared to transition to the workforce or graduate school by the end of the program. Field supervisors also made favorable appraisals of student work performances. Implications for infusing career issues in beginning, middle, and ending courses in an undergraduate liberal arts curriculum are discussed.

Authors: Igbong Dodeye I.
Published: December 2022

An energy and exergy-based performance evaluation of combined recompression supercritical carbon dioxide Brayton cycle and organic Rankine cycle (SCO2/ORC) is presented. A parametric investigation has been performed by varying input parameters such as compressor outlet pressure , SCO2 turbine temperature , SCO2 mass flow rate , flow split fraction, LTR effectiveness and HTR effectiveness. R1234ze, R1234yf, and R245fa working fluids were considered in the bottoming cycle of SCO2/ORC. Results obtained revealed that the R1234ze-based SCO2/ORC system demonstrated the highest thermal and exergy efficiency of 55.87% and 73.13% respectively, at  = 30MPa and  = 3900C; 51.47% and 80.39% at  = 3kg/s when the split fraction is between 0.357 and 0.4; 52.19% and 71.44% at  = 0.95; and 52.19% and 71.44% at  = 0.95. However, the R245fa-based SCO2/ORC system is observed to have the lowest thermal and exergy efficiency. The maximum exergy destruction is seen to occur in the gas heater with 36.97% (8.45kW) of input exergy destroyed in this component. It is followed by the recompression compressor at 17.17% (3.93kW) and the SCO2 turbine at 16.03% (3.67%), with the ORC pump at 0.157% (0.036kW) having the least exergy destroyed.

The purpose of this study was to examine the factors affecting land fragmentation and willingness to exchange farmland in Gombe and Bornu states, Nigeria. The statistical population of this study were participating farmers of the Dadin-Kowa Irrigation Scheme in Gombe and Borno state. Using a multi-stage sampling technique and Taro Yamane formula, 284 rice farmers were selected and data were collected through structured questionnaire. The result of the Tobit regression model shows that the value of the F-Statistics was significant at one% level of probability. Furthermore, the value of the Pseudo R square (R2) was 0.34, indicating a relationship of 34% influencing factors and land fragmentation. The analysis indicated that the coefficient of distance of farm to homestead (0.041) and number of farm holdings were positively influencing the level of land fragmentation while the coefficients of farm size (-0.047) and farm income (-0.054) were negatively influencing the level of land fragmentation. The results of logit regression model revealed that LR chi2 value was significant at 1% level of probability. This indicates the goodness of fit of the model and the joint significance of all the variables used in it and concludes that there are factors that greatly influence the willingness of the rice farmers participating in the DKIS irrigation scheme, to exchange their farmlands. Relatively, age (0.03), farm income (0.00), size of farmland (1.44), soil fertility (2.03), price of farmland (0.00), distance of farm to homestead (0.57), distance of farm to the market (0.50) were the variables that positively influence farmers’ willingness to exchange their farmland. On the other hand, gender (-1.84), duration of rent (-0.89) and distance of farm to main road were the variables found to negatively influence farmers’ willingness to exchange land. The study concluded that the farmers were operating on fragmented land and identified the factors influencing land fragmentation in the study area. The study also concluded that the farmers were willing to exchange their farmlands. Hence the study recommends that for effective farm management services, there is need for capacity building training and sensitization programs to educate the farmers of the importance of working in a less fragmented land using every available incentive tools. Governments should provide livelihood security and economic compensation to farmers who are willing to exchange their farmlands under the irrigation scheme.
Revisiting Sinai Covenant Theology, Its Values and Resonances for Today
Authors: Udoekpo Michael Ufok
Published: December 2022

The relevance of Sinai covenant (Exod 19-24, 32-34; Deut, Josh-2kings) in Hebrew and Christian religions cannot be overemphasized. It is a point of departure for understanding Israel’s basic religion and its components: God’s relationship with his people, the kingship of God, revelation and liberation from myth. It also illumines the riches of Israel’s history, its persons, liturgy, rituals, cults and commandments, the role of the prophets, fulfilled in Christ, the Messiah stressed by our honoree in the course of his ministries. Many would see it as a conditional and relational covenant binding both God and his people. Its meaning, nature, and patterns as discussed historically, pastorally and contextually in this essay, went through various roots of nuances and shifts in the ancient Near East, Hebrew, Greek and Roman cultures, including commitment, faithfulness, resilience, and obedience, trust in divine providence and sharing together. Finally, its relevance, NT resonances and theological importance of Sinai Covenant for the church in African and beyond are highlighted.

This work presents a systematic approach to evaluate and study the effect of fibre aspect ratio and fibre volume fraction on the tensile strength, ultimate elongation, modulus of elasticity, strength and impact energy of oil palm empty fruit bunch fibre reinforced polyester composites. Hand-lay-up technique was used in the fabrication of the composite materials. Response surface methodology was used to study the effect of the selected factors on the mechanical properties of oil palm empty fruit bunch fibre reinforced polymer-based composite. The optimum fibre aspect ratio and fibre volume fraction for each mechanical property was determined. From the result of optimization, the maximum value for tensile strength obtained was 12.15N/mm2 at a fibre aspect ratio of 64 and fibre volume fraction of 26%. The maximum value for ultimate elongation was obtained as 1.939% at a fibre aspect ratio of 124 and fibre volume fraction of 50%, the maximum value for modulus of elasticity was obtained as 1509 N/mm2 at a fibre aspect ratio of 124 and 34% volume fraction. The maximum value for toughness was obtained as 0.12 N/mm2 at a fibre aspect ratio of 89 and a volume fraction of 30%. The maximum value of impact energy was obtained as 307.72J/m (5.77ft-lbs/in) at 28% fibre volume fraction and an aspect ratio of 69. The maximum value of impact strength was obtained as 4.57N/mm2 at a 36% volume fraction and an aspect ratio of 64.

Packaging products are being developed by PT. ATMI IGI – Center. The process of making these products uses the Vacuum forming method. The packaging product is made of PP (Polypropylene) and is used to pack strawberries. There are several problems during the production process, one of which is that there are still product defects burning or often called burn marks. These problems are caused by the machining parameters that have not been standardized, and based on trial eror or experience of the operator. The vacuum forming machine used in this production is the Formech 508FS Vacuum Forming machine. The optimized parameters are heat zone, heat time, and stand by temperature. Optimizing these parameters using the Taguchi method, with an orthogonal array with 9 trials, and the selected signal to noise ratio (SNR) is smaller is better. The response of this research is the reduction of burn mark product defects. The results showed that to reduce burn mark product defects, is to set the parameter heat zone 1 by 90%, heating zone 2 is 80%, heating time 45s, and stand by temperature 60%. Based on this arrangement, the product defects obtained only reached 13%. PT. ATMI IGI-Center is expected to be able to use these parameter settings for the strawberry packaging production process.

Indonesia has more than ten thousand islands, making it an archipelago; therefore, the distribution of learning media and facilities over the country is difficult. This condition may affect the learning material delivery and the student's understanding. Thus, the do-it-yourself (DIY) learning media helps to overcome this condition. We investigated the usefulness of applying appropriate technology through the 3D printing technique to fabricate learning media inspired by local wisdom to meet the needs of learning media. The students were guided by a project-based learning (PjBL) method to find the problem, design their learning media, fabricate it using a 3D printer, and expected to be applied to deliver the teaching material in the class. This study aimed to observe the implementation of the designing process based on theory to reality. A qualitative method and questionnaire were used to measure student's responses. We found that PjBL learning based on a 3D printing project increases students' motivation through creativity and effectiveness in delivering the teaching materials. Furthermore, 3D printed-based learning media can easily be fabricated, producing less waste.
