Synergistic influences of ground granulated blast-furnace slag and silica fume on the viscosity of extremely low W/B cement pastes
Tập 62 Số 4 - Trang 748-759 - 2024
Particularly with a low water/binder ratio, the synergistic effects of supplemental cementitious materials (SCMs) have drawn a lot of interest in improving the characteristics of cement-based products. The effects of SCMs, such as silica fume (SF) and ground granulated blast furnace slag (GGBS) with varying fineness, on the setting time, saturation point, and viscosity of ultra-high performance ce...... hiện toàn bộ

EVALUATION OF PROBITOIC POTENTIAL OF LACTOBACILLUS STRAINS FROM FERMENTED FOODS AND FEACES OF INFANTS
- 2023
Lactobacillus strains are a major part of the probiotics, microflora of the intestine and of fermented foods. The aim of this study was to evaluate the potential probiotics of six Lactobacillus strains (L. fermentum 39-183; L. plantarum subsp.plantarum P-8; L. casei ATCC 334; L. rhamnosus ATCC 8530, L. brevis KB 290 and L. fermentum JMC 7776). Probiotic properties such as acid tolerance, bile resi...... hiện toàn bộ

Initial establishment of a multiplex real-time PCR assay for simultaneous detection of common colistin and carbapenemase genes
Tập 62 Số 3 - Trang 521-529 - 2024
Carbapenem and colistin are often used as last-resort treatment for Gram-negative multi-drug resistant (MDR) bacteria. Nevertheless, co-resistance of these drugs is threatening the global healthcare system. Rapid and accurate detection of carbapenem and colistin resistant bacteria is critical for adequate antibiotic therapy and infection control, particularly in the context of an outbreak. The pre...... hiện toàn bộ

QSAR modeling and molecular docking studies on benzimidazole derivatives as anticancer agents
- 2022
Abstract. The triple-negative breast cancer cell line MDA-MB-231 has been known as one of the most tenacious cancer cancer cells and paid attention by many researchers. A two-dimension quantitative structure-activity relationship (2D-QSAR) model of 131 benzimidazole derivatives was developed to relate the chemical–biological interactions and predicted the half maximal inhibitory concentration (IC5...... hiện toàn bộ

Modelling carbon dioxide gas emission from Notopterus chitala fish ponds by stella software
Tập 61 Số 6 - Trang 1038-1049 - 2023
The rapid development of the areas of Notopterus chitala fish ponds in Hau Giang province in recent years has raised a question about greenhouse gas emissions, in the form of total carbon dioxide equivalents (CO2e). There are many parameters that affect greenhouse gas emissions in a fish pond, such as amount of feed, dissolved oxygen (DO), chemical oxygen demand (COD) in the water, pH, water tem...... hiện toàn bộ

Preparation of hydrogel based on cellulose from sugarcane bagasse
Tập 62 Số 4 - Trang 737-747 - 2024
In this study, the preparation and characterization of hydrogels from sugarcane bagasse were investigated. The preparation of hydrogels was made with cellulose extracted from sugarcane bagasse, ammonium persulfate as initiator, acrylic acid as monomer and N,N’-Methylenebisacrylamide as crosslinking agent. The characterization of structure and properties of the hydrogels were carried out through Fo...... hiện toàn bộ

Purification and characterization of laccase from the white-rot fungus Pleurotus pulmonarius VAST02.42
- Trang - 2024
Laccase (EC 1.10.3.2) is a multi-copper oxidase that utilizes molecular oxygen to oxidize phenolic rings to phenyloxy radicals. Due to its capability to use a wide variety of phenolic and non-phenolic substrates, this oxidative enzyme has potential applications in the food, pharmaceutical, and environmental industries. In the present study, a laccase (PleuLac) from the white-rot fungus Pleurotus p...... hiện toàn bộ

Effects of graphene content on formation and characteristics of char layer in intumescent coating
Tập 62 Số 5 - Trang 906-914 - 2024
This study provides a better understanding of the role and mechanism of graphene nano-platelets used as a flame-retardant filler in a commercial intumescent acrylic-based formulation. Through thermogravimetric analysis, the morphology and mechanical properties of the char layer as well as the influence of graphene on the expansion ratio and compression force are clarified. The achieved results dem...... hiện toàn bộ
