The results show that the ultra-cross linking adsorption resin, NDA-99, is an effective adsorbent to treat the coking waste water when its pH is 4.0 and the absorbing flux is 40 mL/h, and the mono-column wastewater treatment capacity is 300 mL per batch. Under the condition of 50degC, 10 mL 8% NaOH + 10 mL 4% NaOH + 20 mL water is selected as the desorption reagent, and the flux is WmL/h. After the treatment process, the concentrations of volatile phenol and COD decrease from about 1 380 mg/L to 12 mg/L, and 15 500 mg/L to less than 650 mg/L respectively. The raw phenol desorption solution can be recovered just as the high concentration desorption solution by isopropyl ether extraction-distillation. Thus, the resource recycle of phenol in coking wastewater is carried out.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"48 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81779495","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}

To overcome the shortcoming of massive memory requirements of the 2DPCA and 2D-FPCA, we introduce K2DPCA plus 2DPCA method, which needs smaller memory space and has higher discernment rate, and computational efficiency is higher than the standard KPCA /K2DPCA/(2D) 2 FPCA method.

After pretreatment, the mixed wastewater of regenerated-paper making is put into the six soil columns. There are 16 kinds of hydraulic loading cycles made of 4 kinds of flooding-drying ratios (1:6, 1:4, 1:2, 1:1) and 4 kinds of flooding time (4 h, 8 h, 12 h, 16 h). As a result, the systems adsorb ions periodically, adsorption is mild while release is rapid, and the periods of adsorption and release are about 40 hours, respectively. The removal of COD mainly depends on aerobic biodegradation in the aerobic-anaerobic alternate zone. The COD removal of unit height is more because of better reoxygenation effect when the soil column is shorter. Blocking mainly exists in the shallow surface of the system.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"19 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82268124","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}

We used a short-term laboratory incubation to simulate effects on the potential CO 2 emission of peatland soil in Mohe, China under soil temperature (5, 10 15 and 20degC) and soil moisture (0, 30, 60, 100%WHC and completely water saturated). The rates of peat carbon mineralized decreased greatly in the earlier phase, but became stabile after 20 days and total carbon mineralization ranged 20.04 to 112.92 mg across sites and experiment treatments. Carbon mineralization rates decreased with soil depth, increased with temperature and reached highest rates at 60%WHC at the same temperature for all treatments. The calculated Q 10 values ranged from 1.878 to 2.181, varying with the soil depths and soil moisture. The sensitivity of C flux to moisture depend on temperature. However the Q 10 was not significantly affected by soil moisture and depth. We developed a two compartment model to predict the measured CO 2 emission as a multiplicative function of temperature and moisture and the model predicted C flux very well (R 2 >0.888, P<0.001). Our results indicate that the Mohe peatlands would lead to a positive feedback effect on climate change. It is necessary to include such responses in models science they might represent a potential C emission source to peatland ecosystem.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"14 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82491128","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}

Four Ti surfaces of dental implants were compared through different systems in vitro. The surface roughness of Ti was measured by TR240 mobile surface roughmeter. hPDLCs were seeded on Ti and their response to smooth and rough surfaces manufactured from Ti was examined by cell morphology, acridine orange fluorescent staining and alkaline phosphatase (ALP) activity. The surface roughness data of the samples for Group A to D was 0.5995plusmn 0.0083, 0.4065 plusmn 0.0046, 0.3588 plusmn 0.0118 and 0.0087 plusmn 0.0022 mum respectively (F = 6190, P < 0.0001). There was significant difference in surface roughness between all the groups (P < 0.001). hPDLCs were fusiform in shape after they were seeded on Ti, simultaneously few hPDLCs were triangle or polygon in shape. hPDLCs exhibit decreased proliferation on rougher surfaces based on reduced cell amount through the fluorescent staining. hPDLCs had decreased ALP mRNA expression when grown on rougher surfaces.
