Moreover, FTIR analysis indicated that Si participated hydrolytic process of Fe(III). Oil and COD removal efficiency of PFSiS in treating oily wastewater were also evaluated. Under the optimum conditions, oil removal efficiency in the range of 95-97% and more than 60% of COD was removed. Additionally, the PFSiS coagulants exhibited a better coagulation performance than polymer inorganic coagulant, i.e. PFS (Poly Ferric Sulphate).","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"22 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":"81736726","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}

EEG recordings provide valuable information about electrical activity of the neurons in the brain, so it is an important tool in studying and recognizing several neurological disorders like epilepsy. The main goal of this paper was to distinguish different characteristics EEG between pilocarpine-induced and penicillin- induced epileptiform discharges using time-frequency analysis. The results showed that in the course of epilepsy, changes of the frequency and the energy were characteristic. High frequency and high energy distribution period was unsynchronized in pilocarpine-induced epileptiform discharges, especially before onset, EEG appeared the highest frequency, but energy was the lowest. However, frequency was lower in the whole process and energy increased significantly after the attack in penicillin- induced epileptiform discharges. These differences between pilocarpine-induced and penicillin-induced epileptiform discharges may relate to respective excitatory mechanism which needs studying further.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"13 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84208517","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 order to validate our method, superimposed inhalation SPECT, perfusion SPECT and low dose CT image triples were collected obtained by a hybrid SPECT/CT camera at the same time. A known transformation was applied to the low dose CT to simulate a misalignment, followed by an optimal transformation search performing our extended normalized mutual information-based (eNMI) method. For comparison and evaluation, the low dose CT was also registered to both inhalation and perfusion images one-by-one applying a dual-normalized mutual information-based (dNMI) method. Comparative results have shown that our eNMI method worked with minimal registration error and number of iterations, hence it can be successfully applied to stand alone performed low dose CT - SPECT registrations.

The result showed that the decrease of firmness, soluble solids content and titratable acidity was slowed down by chitosan coating during the storage. The activity of SOD, CAT, PPO in the chitosan coating plum were higher than that in the control, but POD activity in the chitosan coating plum was lower than that in the control. Chitosan coating has the potential to maintain postharvest quality during storage at ambient temperature. The chitosan coating has more effective application in our study, which could not only be due to reducing the respiration rate and inhibiting the softing process, but also to increasing the activity of SOD, CAT, PPO in the fruit.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"17 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":"84583662","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}

Here, a random sample of 100 developing fruits from 7-year-old early maturing nectarines (Prunus persica L. Batsch cv. Ruiguang 5) was used as test material. The shape index and growth index of the sampled nectarines was comparatively analyzed to show the relation between fruit un-uniform growth and their split-pit formation. The split-pit fruits were found to have a higher degree of un-uniform growth than that of the normal fruits, which were demonstrated by higher ratio of transverse diameter/lateral diameter and bigger difference between the flesh thickness of the two sides in the middle part of the fruits (along the line of the transverse diameter) about twelve weeks after full anthesis (p < 0.05). Subsequently, a higher degree of unbalanced distribution of IAA and especially ethylene was observed in the split-pit fruits compared to the normal fruits, which may correlate with un-balanced expansion of the nectarines flesh. Higher concentration of IAA and especially ethylene was found in the middle part of the split-pit fruits than those in the sutures, while those in the normal fruits were not significant. Furthermore, the caliosity was specifically observed in the internal surface of the split-pit nectarines endo carp as early as four weeks after full anthesis, but not in the normal nectarines. The occurrence of caliosit in the endo carp may be an early signal of spilt-pit.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"69 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":"85882722","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}
