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(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)
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)
How many different colors are sufficient to color the countries on a map in such a way that no two adjacent countries have the same color? After examining a wide variety of different planar graphs, one discovers the apparent fact that every graph, regardless of size or complexity, can be colored with just four distinct colors. The famous four color theorem,(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)
The P versus NP problem is a major unsolved problem in computer science. Informally, it asks whether a computer can also quickly solve every problem whose solution can be quickly verified by a computer. It was introduced in 1971 by Stephen Cook in his seminal paper "The complexity of theorem proving procedures" and is considered by many to be the most(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)
