The results show that the highest concentrations of the three kinds of nutrients are located in the northern parts of Zhushan Bay and Meiliang Bay, and tend to spread from north to south and from west to east. The maximum total nitrogen concentration appeared in the north as early as 1-2 months earlier than in the south and showed a tendency to appear 1-2 months earlier than the past in various stations. High levels of total phosphorus remained progressively shorter periods from north to south. The maximum level of chlorophyll a appeared gradually later from north to south. As the southeastern region was affected by temperature, the peak there appeared twice in a year. Changes in levels of total nitrogen, chlorophyll a and biomass appeared to have significant inter-annual cycles. Changes in levels of biomass showed a 4-month lag in comparison to nitrogen.","PeriodicalId":6396,"journal":{"name":"2010 4th International Conference on Bioinformatics and Biomedical Engineering","volume":"6 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2010-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89710253","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}

Conventional elastography computes the strain from the gradient of the displacement estimates between gated pre- and post-compression echo signals. Although elastography has been proven to be a potential diagnosis tool for breast/prostate tumor, vascular stiffening and hepatocirrhosis diseases, the application of frequency compounding in elastography to reduce coherent artifact of elastic imaging has rarely been reported. In this paper, a new method called Transmit-side Frequency Compounding for Elastography (TSEC) is proposed, which involves using weighted compounding of different frequency sub-elastograms. The sub-elastograms are formed from the corresponding probe center frequency echo signal pairs reflected from the tissue ROI. Due to the frequency dependent reflection process, these sub-elastograms should have different speckle pattern. Upon compounding these sub-elastograms, the amount of speckle in the resultant strain image is reduced. The effect of TSFC are investigated through phantom experiments, which confirms the reduction in strain image artifact is accomplished with no sacrifice of real-time ultrasonic imaging as well as a measurable improvement in SNRe and CNRe.","PeriodicalId":6396,"journal":{"name":"2010 4th International Conference on Bioinformatics and Biomedical Engineering","volume":"13 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2010-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84359254","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}

After adding nitrogen fertilizer, the pH value of soil would increase, which consequently led to the water soluble fluoride (Ws-F) increase. The result indicated that the pH value has significantly positive correlation with the content of Ws-F, and high pH value will make the fluorine contamination of soil become worse.","PeriodicalId":6396,"journal":{"name":"2010 4th International Conference on Bioinformatics and Biomedical Engineering","volume":"41 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2010-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73666823","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}
