Detailed analyses were undertaken of the natural constituents red yeast rice, a traditional Chinese medicine and food known for centuries to improve blood circulation. Preparation rice following ancient methods by fermenting fungal strain Monascus purpureus Went on moist sterile indicated presence group metabolites belonging monacolin family polyketides, together with fatty acids, trace elements. The these compounds may explain in part cholesterol-lowering ability associated this food.
Bioassay-directed fractionation of the cytotoxic antileukemic extracts Prunella vulgaris, Psychotria serpens, and Hyptis capitata has led to isolation ursolic acid as one active principles. Ursolic showed significant cytotoxicity in lymphocytic leukemia cells P-388 L-1210 well human lung carcinoma cell A-549. It also demonstrated marginal KB colon (HCT-8) mammary (MCF-7) tumor cells. Esterification hydroxyl group at C-3 carboxyl C-17 compounds with decreased lines, but equivalent or slightly...
As a fast-developing technique for in situ multi-element analysis method, laser induced breakdown spectroscopy - LIBS is, however, developing slowly on liquid due to some technical difficulties. We propose new namely capillary mode, quantify the concentrations of elements solution using LIBS. A Nd:YAG with repetition 10 Hz were used analyze Na2CrO4 and no any sample preparation measurements. The experimental results show that splashing by pulses is decreased significantly pollution mirrors...
The influence of water on the mechanical properties rocks has been observed by many researchers in rock engineering and laboratory tests, especially for sedimentary rocks. In order to investigate effect saturation low-permeability rocks, uniaxial compression tests were conducted siltstone with different contents. effects strength, elastic moduli, crack initiation damage thresholds levels. It was found that 10% level caused more than half reductions properties. A new approach is proposed...
Fractures are widely present in subsurface formations, and fracture extension under ultralow temperature conditions is important for tasks such as liquid nitrogen fracturing underground storage of natural gas or air. Therefore, the toughness sandstone ultralow-temperature was investigated using three-point bending tests NSCB specimens. The specimen damage processes were monitored DIC technique, changes pore microscopic characteristics after treatment observed CT SEM. results show that dry...
Abstract This research proposed a vibration monitoring device based on piezoresistive flexible sensor with microstructured surfaces to achieve simple acquisition of information in the driver’s cabin automobiles. The shape, size and arrangement mode microstructures performance were investigated by finite element simulation. polydimethylsiloxane/hydroxylated multi walled carbon nanotubes (PDMS/MWCNTs-COOH) composite membranes prepared combination high-pressure spraying spinning coating method....
Abstract Moiré superlattices are formed when overlaying two materials with a slight mismatch in twist angle or lattice constant. They provide novel platform for the study of strong electronic correlations and non-trivial band topology, where emergent phenomena such as correlated insulating states, unconventional superconductivity, quantum anomalous Hall effect discovered. In this review, we focus on semiconducting transition metal dichalcogenides (TMDs) based moiré systems that host...
In the 21st century, rapid technological advancements have presented various challenges in product quality management for enterprises. A comprehensive system supports entire lifecycle, while effective production decision-making enhances competitiveness. Each step decision process impacts profitability. Markov chains can be utilized to identify and define states behaviors of products throughout their journey from sale. This approach aids determining optimal regression strategies different...
