The study therefore aims to determine its physicochemical and microbiological characteristics in order to better understand the foundation of these ethnic differences. A survey was conducted with 30 producers selected on the basis of their ethnicity in six districts of the city of Maroua. The processes were followed and the samples collected for a physicochemical and microbiological characterization. A principal component analysis was performed in order to group the furdu indicators in relation to the producing ethnic groups. The obtained results show a similar production process for all ethnic groups with a differentiation in the duration of certain unit operations and the material used. Similarities appeared between the furdu made by Moundang, Lamé, and Mafa tribes, characterized by high protein (5.05-5.94 %), free amino acids (4.45-4.93 %), reducing sugars (10.84-11.84 %), carbohydrates (13.62-14.56 %) content and energy values ??(72.28-82.04 %) and the furdu of Guiziga and Laka ethnics, characterized by high polyphenol (39.48-48.48 %), tannin (7.48-7.68 %), flavonoid (10.26-10.35 %), FRAP (54.08-54.22 %) and DPPH (23.60-24.28 %) contents. The values ??of total mesophilic aerobic flora, fungal flora and total coliforms of the different samples were all higher than the standard. If the construction of the quality of the drink is based on its nutritional potential among the Moundang people, it is driven by the high alcohol content among the Guiziga group, while the consistency came in pole position among the Mousgoum tribe. The consumption of this popular drink, justifies a control of the microbiological, toxicological and sensory quality to meet the regulatory challenges of the market.</p> 2024-12-04T00:00:00+00:00 Copyright (c) 2024 American Scientific Research Journal for Engineering, Technology, and Sciences https://www.asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/11066 Some Solution Methods for Lane-Emden Differential Equation when the Polytropic Index is Three 2024-09-24T09:14:53+00:00 Sashinka Wimaladharma wimaladharma@kln.ac.lk Dinuka de Silva dinuka@kln.ac.lk <p>The Lane-Emden equation is one of the widely used and challenging equations in nonlinear dynamics. It is a central equation in the theory of steller structures. In this paper, Lane-Emden equation when has been solved using few different methods. Pade approximant has also been calculated of the obtained solution. The results obtained using semi-analytical methods are compared with the solutions obtained using well-known numerical methods namely Runge-Kutta’s fourth order method and ODE 45 graphically.</p> 2024-10-16T00:00:00+00:00 Copyright (c) 2024 American Scientific Research Journal for Engineering, Technology, and Sciences https://www.asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/10682 Could Econometric Models Predict Higher Inflation? Time Series Modelling and Inflation Rate Forecasting 2024-07-04T10:21:04+00:00 Mir Md. Moheuddin mirmoheuddin2305@gmail.com Saddam Hossain s.hossain656@gmail.com <p>This research utilizes annual time series data on HICP to identify the most suitable econometric model for forecasting the inflation rate in Poland. In this study, we have compared and applied the Autoregressive Moving Average (ARMA) model and the Vector Autoregressive (VAR) model to predict the annual inflation rate using data from January 2002 to December 2020. Various methods are employed to determine the optimal model specifications, followed by the generation of forecasts within a rolling estimation window. The results consistently indicate that the ARMA (2, 0) model outperforms other specifications in forecasting Polish inflation. These findings suggest that the inflation rate is expected to continue its downward trend in the coming years. Consequently, this study offers valuable insights for guiding future actions and policymaking in response to prospective inflation scenarios.</p> 2024-10-26T00:00:00+00:00 Copyright (c) 2024 American Scientific Research Journal for Engineering, Technology, and Sciences https://www.asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/11174 Stabilization of Laterite Soil with Pozzolan-Calcium hydroxide Binders for Construction of Low Volume Roads in Mbeya Tanzania 2024-10-21T14:24:18+00:00 Duwa Hamisi Chengula chengula@yahoo.com <p>The study stabilized Laterite soils by using Natural pozzolan – Calcium hydroxide binders for the aim of improving its strength. Characterization and stabilization process of Laterite soil under laboratory conditions were conducted. The Laterite soils used for this study were classified as clayey soils with a plasticity index of 33%, a maximum dry density of 1525 kg/m<sup>3</sup> and a California bearing ratio of 6.7%. Natural pozzolan – Calcium hydroxide binders (PoCH) at proportions of 70%:30% (70Po30CH) and 50%:50% (50Po50CH) were used as binders to Laterite soils. The binders were replaced to Laterite soils at dosages of 5%, 10%, 15%, 20%, 25%, and 30% by weight. The stabilized Laterite specimens were cured for 7, 28 and 48 days. The results indicated that the addition of Natural pozzolan – Calcium hydroxide binders to the Laterite soils reduced the plasticity indices from 33% to 13.7% at 30% of 70Po30CH and from 33% to 10.8% at 30% of 50Po50CH binders.The unconfined compressive strength (UCS) values of Laterite soils mixed with 20% of 70Po30CH and 50Po50CH and cured for 28 days were 1.4 MPa and 1.2 MPa respectively. The study revealed that the strength of Laterite soils can be improved through stabilization with 70Po30CH and 50Po50CH binders at dosage of 10% to 25% for the construction of improved subgrade and subbase layers of low-volume roads in Mbeya Tanzania.</p> 2024-11-20T00:00:00+00:00 Copyright (c) 2024 American Scientific Research Journal for Engineering, Technology, and Sciences https://www.asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/10931 Digitalization of BSA Colorimetric Sensor Data with RGB Analysis Integrated into Smartphone 2024-08-24T15:09:50+00:00 Ekin Akman ekinakman02@gmail.com Semih Çalamak semih.calamak@lokmanhekim.edu.tr <p>Today, with the digitalization of data, our project has been carried out to contribute to the developments in data analysis in telemedicine. A method has been developed for the detailed analysis of Bovine serum albumin, which is also used in cancer treatment, at different concentrations, with the use of an RGB data-based software that provides more detailed information and color homogenization compared to the colorimetric sensors used under the heading of point-of-care systems (POC). In this way, diagnostic technologies have become necessary to minimize the margin of error in health technologies and develop systems that do not cause economic difficulties. It is essential for the development of the health sector in our country and in the world to realize technological innovation in bedside systems and to contribute to the formation of this field. Our project, which we developed to make more detailed analyses with digitalization, wanted to draw attention to the importance of bovine serum albumin, an antimicrobial antigen used in many examination methods today, in diagnostic methods and to increase its effectiveness.</p> 2024-10-30T00:00:00+00:00 Copyright (c) 2024 American Scientific Research Journal for Engineering, Technology, and Sciences
