And utilize the observed data and the calculating results of the water quality concentration field of the lake to achieve the water environmental capacity in the dry season. From the results, it is shown that the velocity of the lake is small and the direction is from the northwest to the southeast as the topographic form is the northwest higher than the southeast. Both the observed and the computed results of the COD concentration show that they are smaller than the standard limit value of COD emission concentration. The results will provide the advice to improve the water environmental quality of the lake in Changshu City, the ecological regime and scientific management of the lake.","PeriodicalId":6399,"journal":{"name":"2008 2nd International Conference on Bioinformatics and Biomedical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83759168","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}

This paper explores the theoretical background of laser Doppler and speckle techniques. Four applications in measurement of tissue blood perfusion are introduced which are: laser Doppler flowmetry (LDF) , laser Doppler perfusion monitor (LDPM) , laser Doppler perfusion imager (LDPI) , laser speckle contrast imaging . In this paper we will describe theses four techniques in brief separately and then we will compare them with each other and with other methods for assessment of microvascular blood perfusion. First, we will explain LDF technique in brief. Then basic principles and components of the LDPM and LDPI instrumentation are discussed. At the end laser speckle contrast imaging technique will be introduced. Some image examples are given to compare the commercialized laser Doppler technique and prototype laser Doppler contrast imager techniques.","PeriodicalId":6399,"journal":{"name":"2008 2nd International Conference on Bioinformatics and Biomedical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79649486","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}

Previous studies on model plant Arabidopsis have identified several transcriptional regulators required for fruit dehiscence.

By using bioinformatics, we have predicted the homologous genes of fruit dehiscence-related genes in oilseed rape.

Femtosecond time-resolved absorption spectroscopy has been used to study the process of excited-state energy transfer(EET) among Cars in LH2 excited by femtosecond laser pulse at different wavelength. The characteristic spectra of singlet (Sn) and triplet (T1) excitation Cars were observed in visible spectral region. The results suggest that the singlet EET processes may occur from Cars with shorter conjugation length(n) to that with longer conjugation length besides excitation energy internal conversion. These complicated excitation energy equilibrium in the HL-LH2 from Rps. palustris fulfills within 6 ps. It might imply that the coexistence of many Cars is helpful for Cars serving as photoprotection.","PeriodicalId":6399,"journal":{"name":"2008 2nd International Conference on Bioinformatics and Biomedical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81047121","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}

Based on the corresponding anatomical point landmarks, we also consider a thin-plate spline deformation as a method to solve non-rigid registration for chest X-ray images.

In this study, the generation of trihalomethane (THMs) in the effluent of hospital wastewater during chlorine disinfection process was evaluated. The results showed the formation of THMs increased gently along the increasing chlorine dosages at beginning of the chlorine disinfection, but increased significantly after the chlorine dosages over 20 mg/L. Chloroform was the most abundant THM species and occupied above 40% of the total concentration. The second-order model interpretation of the long-term formation of THMs showed a good linearity and a second-order rate constant of 0.8857 (mg/L)-1s-1 in this experiments.
