With composition acoustic environment as starting point, it finds out implicit environment, introduces design, proposes discusses its specific process with case simulation method, taking nodes in Zhongshan Park, Qi...

Sulfated polysaccharides (GSP) were isolated from the cloned Grateloupia filicina which was cultured in Jiaozhou Bay, Qingdao, China. The yield of GSP was 15.75%. The total sugar and sulfate were 40.90 and 19.89%, respectively. And the average molecular weight was 11.7 KDa. The results of neutral sugar analysis showed that GSP was mainly sulfated polysaccharides of galactose. The experiments fo...

In this paper, grey system theory and DEA are combined to establish a grey DEA model. In traditional DEA model, Input and output values of decision-making groups are all real numbers and real variables. They are replaced by grey numbers and grey variables in grey DEA model respectively. Using positioning solution method of grey linear programming, we prove the necessary condition for grey effec...

Introduction Papillomaviruses (PVs) can cause hyperplasia in the skin and mucous membranes of humans, mammals, non-mammalian animals, are a significant risk factor for cervical genital cancers. Methods Using next-generation sequencing (NGS), we identified two novel strains papillomavirus, PV-HMU-1 PV-HMU-2, swabs taken from belugas ( Delphinapterus leucas ) at Polar Ocean Parks Qingdao Dalian. ...
