In order to investigate the effect of manganese (Mn) deficiency on bone metabolism in chicks, ninety 1-day-old male Arbor Acre chicks were randomly divided into 3 groups and each group were given a diet having a different concentration of Mn (60 mg kg−1, control group; 40 mg kg−1, Mn-deficient group I; 8.7 mg kg−1, Mn-deficient group II). The serum was(More)
In this paper, a new chemiluminescent plant tissue-based biosensor for diamine detection was presented by employing sequential injection analysis (SIA), which facilitates precise fluidic handling and lower consumption of sample and reagents. Pea-seedling tissue acted as the molecular recognition element and was packed in a mini-PTFE column and further(More)
This paper uses Bumblebee stereo vision system to reconstruct the 3D terrain for patrol robot. Firstly, with the selected points in the disparity image, the ground plane equation of the current frame is calculated by the RANSAC (Random Sample Consensus) algorithm, and then estimated and predicted by the Kalman filter. Secondly, the elevation image is(More)
A web service security analysis model based on program slicing is proposed, which can be used to find existence of critical information disclosure vulnerabilities and proliferation of such vulnerabilities in a web service net, and eventually improve protection of critical information. Web service protocol is analyzed to obtain external service interfaces;(More)
A novel flow-injection chemiluminescence (CL) method for the determination of guanine was developed. The procedure is based on the CL reaction of guanine with hydrogen peroxide in borax buffer (pH 8.5) with Co2+ as a catalyst. The calibration graph is linear within the range of 3 x 10(-7)-9 x 10(-5) g/mL. A detection limit of 1 x 10(-7) g/mL, along with a(More)
