Visible reflectance spectroscopy technique combined with three chemometrics methods were applied to predict the age of bloodstains for forensic purposes. The performance of models established by principal component regression (PCR), partial least-squares regression (PLSR), and least-squares-support vector machines (LS-SVM) methods were compared. Three(More)
OBJECTIVE We used the SD rat's bone marrow stromal cells (BMSCs) cultured in vitro to observe the effects of Bugu Mixture on the apoptosis and to explore the molecular biologic mechanism of the treatment of osteoporosis with Bugu Mixture. METHODS BMSCs were separated from the bones of the extremities of SD rats in vitro. The morphologic changes, the(More)
The purposes of this study are to investigate the prevalence of nonresponsive feeding practice (NRFP) and child’s eating behavior (CEB) and to explore the hypothetical association between child’s weight status, NRFP and CEB for 1- to 6-year-old children. In this study, 2423 caregivers of 1- to 6-year-old children are from the Nanjing Maternal and Child(More)
An avionic illumination power supply unit and its modified type are selected as the case study in this paper to discuss the data sufficiency of the result given by Physics of Failure method. Comparing the using information obtained from field operation with the failure data, which is predicted under the help of physics of failure method, the sufficient(More)
To face new challenges appearing in reliability and availability of equipment, Prognostics and Health Management (PHM) is proposed and shows great power in guiding maintenance plan and cutting related costs. Nevertheless, the industrial application of PHM is still immature. This paper will discuss some important points on process system PHM. Firstly,(More)
The present study aimed to investigate the effects of Wenyangbushen formula on the mRNA and protein expression levels of vascular endothelial growth factor (VEGF), osteoprotegerin (OPG), receptor activator of nuclear factor (NF)‑κβ ligand (RANK), and RANK ligand (RANKL) in a rabbit model of steroid‑induced avascular necrosis of the femoral head (SANFH). The(More)
OBJECTIVE To explore the protection on apoptosis and the mechanism of promoting the cytoactive of osteoblast by Morinda Root Polysaccharide through the observations of the cultured osteoblast in vitro. METHODS Prepared blood serum with Morinda Root Polysaccharide and Morinda Root aqueous extract and cultured Osteoblast in vitro with it. The second(More)
Domestic sewage treatment is a hot research topic in recent years. The testing methods for the quality of treated water are usually based on chemical techniques, which are more accurate, but are time-consuming, complex operation, and may lead to secondary pollution. In this paper, we propose an electrical method to detect domestic sewage on different stages(More)
