To distinguish the papers embedded of security thread with which to have the formation method based so that the papers commonly used for counterfeit banknotes were to classify through analysis of the thread’s morphological characteristics, with purpose to provide a new technical means for counterfeit banknotes to have them concatenated and traced into source. The papers of embedding security thread were observed and analyzed with VSC6000 comparator, electronic microscope and energy dispersive spectrometer (EDS), successfully having their embedding security threads delved and known int

At present, with the advance of satellite image processing technology, remote sensing images are becoming more widely used in real scenes. However, due to the limitations of current remote sensing imaging technology and the influence of the external environment, the resolution of remote sensing images often struggles to meet application requirements. In order to obtain high-resolution remote sensing images, image super-resolution methods are gradually being applied to the recovery and reconstruction of remote sensing images. The use of image super-resolution methods can overcome the current

To probe into the distribution and metabolic pathway of flualprazolam plus its main metabolite (α - hydroxylflualprazolam) in rat. 40 SD rats were randomly divided into 4 groups and fasted for 12 hours, with the first group being fed of flualprazolam by gavage as per 0.45 mg/kg and having their respective blood collected from tail vein at different time and each one's urine received every day after administration. The second group was taken as the blank control to the first one. The third group was executed at 0.25h after drug administration, having their respective blood, heart,

Two cases were here reported about abnormal elevation of cadmium concentration in postmortem heart blood of victims who died from non-cadmium poisoning. One dead showed her heart blood was 200-fold higher of cadmium concentration than the upper limit of healthy living people, with the other one demonstrating his 40-fold higher. The autopsy also revealed that different body parts were of discrepant blood cadmium concentration, with tissues being within normal range. Observations were further made about cadmium concentration in venous blood from 100 living people and heart blood from 50 non-c

Vaccines are one of the most effective measures to prevent and control disease. At present, the types of vaccines include traditional inactivated vaccines, attenuated vaccines, protein vaccines and nucleic acid vaccines. However, the antigenic components of these vaccines are mostly bioactive substances, which are easily affected by the environment, such as being easily metabolized in the body and having poor immunogenicity, so they need to be used with adjuvants. Now, the traditional adjuvant has some problems such as complicated preparation, low biological safety, poor stability, and low
