Spach and Their Bacteriostatic Effect on Pathogenic Bacteria of Broiler Origin Processes (IF 3.5) Pub Date : 2024-03-12 Taixia Zhao, Yongshi Hua, Yuanyuan Zhou, Haixia Xu, Wenxin Tian, Zhongbao Luo, Baoqin Huang, Lanming Chen, Li Fan
This study aimed to investigate the antioxidant activity and antibacterial effect of total flavonoids from Persicaria hydropiper (L.) Spach (TFs-Ph) and to provide a theoretical basis for the development of drugs for the treatment of pathogenic Escherichia coli and Salmonella spp. of broiler origin. Firstly, the response surface optimization heating reflux method was used to extract TFs-Ph, and the

Monitoring Yeast Cultures Grown on Corn Stover Hydrolysate for Lipid Production Processes (IF 3.5) Pub Date : 2024-03-12 Afonso Fontes, Ricardo Francisco, Frederico Castelo Ferreira, Nuno Torres Faria, Susana Marques, Alberto Reis, Patrícia Moura, Rafal Lukasik, José Santos, Teresa Lopes da Silva
Microbial oils can be used as an alternative sustainable and renewable feedstock to fossil reserves for producing lubricants and polyurethane materials. Two oleaginous yeasts were grown on non-detoxified corn stover hydrolysate supplemented with corn steep liquor and mineral medium in shake flasks. Trichosporon oleaginosus DSM 11815 displayed the highest lipid production. This strain was further cultivated

Optimizing Short-Term Photovoltaic Power Forecasting: A Novel Approach with Gaussian Process Regression and Bayesian Hyperparameter Tuning Processes (IF 3.5) Pub Date : 2024-03-11 Md. Samin Safayat Islam, Puja Ghosh, Md. Omer Faruque, Md. Rashidul Islam, Md. Alamgir Hossain, Md. Shafiul Alam, Md. Rafiqul Islam Sheikh
The inherent volatility of PV power introduces unpredictability to the power system, necessitating accurate forecasting of power generation. In this study, a machine learning (ML) model based on Gaussian process regression (GPR) for short-term PV power output forecasting is proposed. With its benefits in handling nonlinear relationships, estimating uncertainty, and generating probabilistic forecasts

An Experimental Study on Nodular Iron Machined Surfaces Utilizing a Capable 2D Finite Element Model for Precise Surface Roughness Estimation Processes (IF 3.5) Pub Date : 2024-03-11 Ibrahim T. Teke, Ahmet H. Ertas
Nodular iron plays a crucial role in various industries, especially in large-scale applications such as gearboxes. Ensuring that nodular iron remains free from oil leakage and that contact surfaces are properly aligned is essential, given its operational requirements. Achieving flat contact faces through precise machining is therefore of utmost importance. As surface roughness and flatness are closely
