In the esterification and transesterification reactions involving soyabeansoapstock, sodium hydroxide, methanol and n-hexane were used as catalyst, solvent and co-solvent respectively. The physico-chemical properties of the biodiesel obtained were determinedusing the Association of Analytical Chemist (AOAC) and American Society of Testing Materials (ASTM) methods. The esterification and transesterification reactions were optimised using both response surface methodology (RSM) under design expert 7.0 platform and Particle swarm technique in ANFIS (ANFIS-PSO) using the MATLAB software. The optimized acid value from the esterification reaction using RSM and ANFIS-PSO were 4.956 and 1.488 while the yield obtained were 97.29% and 99.91%respectively with ANFIS-PSO proving to be the better optimization technique in both cases. Comparison plots made for both reactions shows the ANFIS-PSO curve mirroring the experimental and thus signifying a closer trend when compared to the RSM curve. The suitability of the ANFIS-PSO prediction was further highlighted by the error analysis carried out on both techniques. The Residual sum of squares (RSS), Mean absolute error (MAE), Root mean square error (RMSE), Correlation coefficient (R), Coefficient of determination (R²), Adjusted R², Absolute average deviation (AAD) and Mean absolute percent error (MAPE) values for the ANFIS-PSO predictions in both reactions were better than the RSM predictions. It can thus be concluded that soybean soapstock is a viable feedstock for biodiesel production and ANFIS-PSO is a more efficient optimization technique when compared with RSM in esterification and transesterification of soybean soapstock.\u0000","PeriodicalId":502378,"journal":{"name":"Advances","volume":"28 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141836138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Evaluating the Onfarm Performance of True Seed Shallot Varieties in Northwest Ethiopia","authors":"A. Gashu, A. Beyene","doi":"10.11648/j.advances.20240502.12","DOIUrl":"https://doi.org/10.11648/j.advances.20240502.12","url":null,"abstract":"Shallot (Allium cepa L. var. aggregatum) is an important vegetable crop in Ethiopia, but its production has declined in recent years due to a lack of true seed-propagated varieties. This study aimed to demonstrate and evaluate the performance of true seed shallot varieties in three districts of the Amhara region: Fogera, Libokemkem, and Dera. The study involved the participation of host farmers in variety demonstrations and the evaluation of the demonstrated varieties by experienced farmers. Two true seed shallot varieties, DZsht-157-1B and DZsht-91-2B, were compared to the local Bombay red variety. Bulb yield data was collected from one-meter square quadrants, and farmers' preferences were assessed using a direct matrix ranking approach. The results showed that the true seed shallot varieties outperformed the local Bombay red variety in terms of bulb yield. In the Fogera district, DZsht-157-1B and DZsht-91-2B had 40.1% and 0.3% higher bulb yields, respectively, compared to Bombay red. In the Libokemkem district, DZsht-91-2B had a 4.2% yield advantage over the local variety. The farmer evaluation results revealed that the true seed shallot varieties were preferred over the local Bombay red variety in various aspects, such as higher bulb yield, redness, and prolonged food span. The findings of this study suggest that the true seed shallot varieties have the potential to improve shallot production in the study areas and potentially in other parts of Ethiopia. To promote the adoption of these varieties, it is crucial to ensure the availability and accessibility of high-quality seeds to farmers, as well as to educate them on the importance of maintaining the true seed to bulb and bulb to true seed cycle. This will enable the continuous propagation of the true seed shallot varieties and ensure a sustainable supply of high-quality planting material, contributing to the revitalization of shallot production in Ethiopia and enhancing the livelihoods of smallholder farmers.\u0000","PeriodicalId":502378,"journal":{"name":"Advances","volume":" 39","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141681083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the important lessons, contributing to great achievements throughout history is the lesson \"Taking the people as the root\", promoting the role of ownership, creativity and resources of the people in the cause of building and defending the country. This is the cross-cutting ideology that contributes to the revolutionary cause of the Party, overcoming all difficulties and achieving many victories. The civil campaign work of the political system of Dong Nai province in each revolutionary period has different contents and methods, but they all aim at the important goal of strengthening the close relationship between the Party and the People, firmly strengthening the people's trust in the Party; mobilize and attract a wide range of people, arouse the spirit of patriotism, promote the strength of the great national unity bloc for the national development process. In addition to the achieved results, the civil campaign work also has limitations and inadequacies: In some places, the awareness and responsibility for the civil campaign work of the political system is not very deep; not fully aware of the important role and great strength of the People, the great national unity bloc and the idea of \"Taking the people as the root\" in the view that \"Revolution is the cause of the masses\"; the institutionalization and concretization of a number of Party guidelines and resolutions related to civil campaign work have not been timely. The grasping, assessing and forecasting of the situation, especially the People's situation before events and situations arising in complex fields and areas, sometimes and in some places, have not met the requirements.

However, with the current number of completed worker housing of about 2.7 million m², which only accommodates more than 340 workers, the set goal has not been achieved. The reason for not achieving the desired goals is that the mechanisms and policies for developing social housing and housing for workers still have some contents that do not meet practical needs and have not been supplemented or adjusted, timely amendment and completion, such as: participants, beneficiaries, automatic construction investment process, purchase and sale management. The implementation of preferential social housing policies must be done through many steps, so the time to carry out investment procedures is long, the space for innovation and development of social housing is limited as required; The reasonable costs for social housing development have not been calculated correctly or fully. Preferential policies for investors of social housing projects and worker housing are not attractive enough and not realistic enough. On that side, the state budget is still difficult and has not been able to arrange preferential capital for loans for social housing development; There is no mechanism to mobilize reasonable resources to achieve efficiency and system. This article aims to provide a comprehensive and systematic understanding of the current situation of working conditions of female workers in Ho Chi Minh City. The topic of employment conditions of female workers has been studied by many researchers, but certain limitations still exist.

Increasing in the current market mechanism. The more the country develops, in addition to modern technology serving production and business, one of the factors determining the country's development is the labor force, in today's market economy the workforce Workers are students trained in universities, colleges..., the country's young force is very dynamic and capable at work. Therefore, students are a very important human resource that we need to know how to use in the most reasonable and effective way. But the current unemployment situation of students after graduating has greatly affected the economic and social development of the country. So the question for managers and the country is what causes that situation? Is it because the training process at universities still lacks many aspects? or because the State's policies are not reasonable in using labor. Employment after graduation is always a pressing issue not only for students themselves but also for families, schools and society. Having a job that matches the field of training is always the dream of not only students graduating from school but even for those still sitting in university lecture halls. Starting from the importance of employment for students after graduation, the topic \"Improving the ability of students to find jobs in Ho Chi Minh City today\" researches, surveys and evaluates.
