When Cu deficiency is occurred in dairy cows, it’ll be accompanied by many diseases. The main objective of the present study was to explore the correlation between Cu deficiency and oxidative stress of lactating dairy cows and evaluate early-warning index for Cu deficiency. There were divided into two groups based on serum Cu levels: a Cu deficiency group and a control group. Serum levels of ceruloplasmin (CP), superoxide dismutase (SOD), total antioxidant capacity (T-AOC), glutathione peroxidase (GSH-PX), and Cu were analysed. The results showed that CP levels in the Cu deficiency group were significantly lower than in the control group, while T-AOC levels were significantly higher, but there were no significant differences between SOD and GSH-PX levels. Pearson correlation analysis showed that serum CP levels were very significantly positively correlated with Cu deficiency, while serum T-AOC levels were very significantly negatively correlated and SOD and GSH-PX serum levels showed no correlations. Logistic regression analysis showed that CP was a risk factor for Cu deficiency, ROC analysis showed that CP had diagnostic value for Cu deficiency, with a critical value of 13.7 U/l. Hence, CP and T-AOC levels in lactating cows showed strong correlations to Cu deficiency, indicating that serum CP can be used to predict Cu deficiency.","PeriodicalId":17101,"journal":{"name":"Journal of Residuals Science & Technology","volume":"18 1","pages":"85-89"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81600555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental results indicated that the three-step series CRI system led to COD removal of 79.65%, a value 6% greater than that in a system using conventional CRI. Moreover, the effluent water quality of the three-step series CRI system met the first level criteria A as specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2002). Total organic matter and particulate organic matter in the wastewater were removed in the first compartment of the system by 54% and 83%, respectively. The quantity of aerobic ammonifying bacteria decreased from top to bottom along the compartments in the system, and was obviously higher than in the conventional CRI system. The dehydrogenase activity showed an M-shaped variation pattern in which two peak activity values were observed. The COD removal efficiency showed a very significant correlation with the aerobic bacteria quantity (correlation coefficient r = 0.97), and showed a relatively significant correlation with the dehydrogenase activity (r = 0.64). The biofilm mass and the active biofilm mass showed M-shaped variation patterns, and were obviously higher than in the conventional CRI system. The COD removal efficiency showed a relatively significant correlation with the weight of the active biofilm mass (r = 0.73).","PeriodicalId":17101,"journal":{"name":"Journal of Residuals Science & Technology","volume":"80 1","pages":"115-120"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83946243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate that the higher exposed temperatures, the more cracks occurred and the lower ultimate load carrying capacities for the specimens, and the failure mode and load capacity could be increased greatly by external strengthened with CFRP sheets. However, the higher RCA replacement ratio could induced a smaller cracks and higher load capacity, and the specimens with 50% RCA ratio gave the highest load capacity when exposed to high temperature. In addition, the ABAQUS software was employed to conduct finite element analysis (FEA) of STSRC reinforced, and a comparison of results calculated using the proposed model exhibits good agreement with an experimental results.","PeriodicalId":17101,"journal":{"name":"Journal of Residuals Science & Technology","volume":"49 9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91116116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, the significance of water environmental quality evaluation and problems found in available evaluation methods were discussed, with a focus on prior research results. This paper selected ammonia nitrogen (NH3-N), chemical oxygen demand (COD), cyanide, volatile phenol and petroleum as evaluation factors, and established level-evaluating and order-arranging models of water environmental quality on the basis of information entropy and uncertainty measure theory. The uncertainty influence factors based on the real situation were quantitatively and qualitatively analyzed, and the experimental data were used to establish the uncertainty measure function. Also, we adopted information entropy theory to calculate the weight of the index, and determined the level and level order of water environmental quality based on credible degree recognition criterion. The developed model was applied to assess water environmental quality in four sections of Dan River Basin. The results show that uncertainty measure method is reasonable, with the potential significance of assessing water environment quality in the future.","PeriodicalId":17101,"journal":{"name":"Journal of Residuals Science & Technology","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84070025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is found that the creep characteristics conform to Burgers model without considering the change of the creep failure stage. The creep parameters, the principal stress difference and its deviation are analyzed for saturation-dehydration cycles of N = 0, 1, 5, 10, respectively. Results show that the parameters of Burgers model are substantially influenced by the load level. G1 and G2 increase with the increase of axial loading. η1 and η2 decrease with the increase of axial loading. The relationship between the four parameters and the stress difference follows exponential trend. An exponential relation is found between the creep parameters and the principal stress difference for constant saturation-dehydration circles. The creep parameters are approximately exponential functions of the cycle number n for the same principal stress difference. Through curve fitting of the test data, the values of the parameters in Burgers model for the beresitization fractured granite (SγJH) are obtained by considering the water-rock interaction and principal stress difference.","PeriodicalId":17101,"journal":{"name":"Journal of Residuals Science & Technology","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81541304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
