Generalized DUS-Bilal Distribution: Properties and Applications

2025-07-26T10:25:09+07:00

In this article, we proposed a flexible version of the Bilal distribution using the generalized DUS transformation. Its properties are studied. Three methods of parameter estimation, including the maximum likelihood, Anderson-Daring, and Cramer-Von Mises techniques, are used to estimate unknown parameters. Real datasets are used to demonstrate the applicability of the proposed distribution using the three methods of parameter estimation.

Preparation and Characterization of PVDF/NCs/TiO2 Photocatalytic Membrane for Rhodamine b Dye Degradation

2025-06-20T11:35:18+07:00

This study focuses on the synthesis and characterization of polyvinylidene fluoride (PVDF) membranes enhanced with nanocellulose (NCs) and TiO₂ for the removal of rhodamine b (RhB) dye. PVDF/NCs/TiO₂ membranes were fabricated with varying TiO₂-P25 contents (0.18, 0.36 and 0.72wt%). Initially, PVDF and NCs were separately dissolved in dimethylacetamide (DMAc), followed by the addition of TiO₂-P25 nanoparticles. The resulting solutions were cast into membranes using the doctor blade technique and dried at room temperature. Fourier transform infrared spectroscopy (FTIR) confirmed the successful incorporation of both NCs and TiO₂ into the PVDF matrix. Water flow rate measurements were conducted to assess membrane permeability. Photocatalytic activity was evaluated using RhB dye solutions at pH 4, 7, and 10. The results indicated that membranes containing NCs and TiO₂ exhibited superior water permeability and dye removal efficiency compared to pure PVDF membranes. These findings suggest that PVDF/NCs/TiO₂ membranes are promising candidates for the treatment of dye-contaminated wastewater.

Development of Sweetened Condensed Creamer made of Thai Pathumthani Rice (Hom-Pathum) Milk

2025-04-21T11:01:44+07:00

Thai Pathumthani Rice (Hom-Pathum) is a Geographic Indication (GI) product cultivated in Thailand. Plant-based milk production has gained popularity due to its lower greenhouse gas emissions, water use, and land utilization than dairy milk. Sweetened condensed cream is a concentrated dairy product made by eliminating a lot of water from cream and adding sugar for stability, texture, and shelf life. Its creamy texture, high fat content, and sweetness make it popular in confectionery, bakery, and desserts. This study was aimed to utilize the whole Hom-Pathum rice for Hom-Pathum rice milk (HPRM) production and formulate a sweetened condensed creamer (SCC) product. The acquired SCC was assessed for its physical, physico-chemical, biological activity, chemical composition, and microbiological properties. The results showed that the ratio of rice to water 1:10 (%w/v) was suitable for HPRM production and processes to SCC product. The color of obtained SCC made of HPRM (HP-SCC) was significantly different in L^* value (76.31±2.43) when compared to commercial sweetened condensed cream (CSCC), 72.83±3.01, (p<0.05). No difference was observed in pH, water activity (A_w)and total acidity value of final product compared with CSCC (p>0.05). The viscosity of HP-SCC showed the consistency (7,642.63±29.78cP) with commercial product. The HP-SCC enhanced antioxidant activity and eliminated hazards from pathogenic bacteria, resulting in a safe product. These findings may serve as preliminary results for the creation of HPRM and HP-SCC products that fulfill consumer quality standards.
