Se-enriched Lactobacillus bulgaricus (L. bulgaricus) was generated by administration of sodium selenite (0, 1, 4, 8, 16, 32, and 64 mg/L, respectively) in MRS medium and enriched selenium manifestation in L. bulgaricus was investigated using transmission electron microscopy and energy-dispersive X-ray spectrometry and alterations of essential elements and amino acids in the organism were evaluated. We demonstrate that administration of sodium selenite in the dosage of 1-16 mg/L is suitable for selenium enrichment in L. bulgaricus and can enhance nutritive value in the organism by elevating the contents of essential elements including P, Mg, Mn, Zn, Ca, and total amino acids as well as reducing selenite to insoluble elemental selenium, an electron-dense and amorphous Se (0) granule, thereby depositing it both in the cytoplasm and in the extracellular space of L. bulgaricus. Thus, Se-enriched Lactobacillus can provide a potential dietary source of nontoxic selenium and functional regulator used for food and medical industry.

For the request that was proposed in research and design for measurement research and payment system of the highway engineering: flexible business process control and integration management issues of spatial and attribute data and so on. The article proposed a method in which GIS integrated with workflow: using construction supervision for highway measurement and payment workflow as main line, using component software technology as basis ,and with a development platform achieving the integration of workflow with GIS. Based on the fusion technology, the article completed the technical framework and design of the system. The feasibility and effectiveness of this fusion technology was verified in the practical application.

Based on background, taking the engineering construction material information management system to replace the traditional artificial management mode in recent years has caused extensive concerns in the construction enterprises. Then, this paper used .NET technology to implement the construction material information management system.
