XMT enabled prediction of structure and permeability of flocculated structures and sediments

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2005年第12期6卷 1367-1373页

3D visualisations of the microstructure of flocculated particulates and sediments using optical confocal laser mi- croscopy and high resolution X-ray microtomography (XMT) methods are described. Data obtained from in-situ measurements should enable direct computation of the properties of solids assembly (shape, size, contact area) and their permeability to fluids. A specific application relating to the formation of silica aggregates is described from which the behaviour of sediments containing these materials can be predicted on the basis of a bench-top test and the use of a Lattice Boltzman simulation. It is proposed that the method can potentially be used to predict trends such as the filtration behaviour of porous structures under different states of compression. This offers a significant benefit in assisting the formulation design of flocculated materials pertinent to a number of industrial sectors wishing to design optimal filtration or relevant operations.

Objective:To assess the seasonality of the bacterial meningitis and the antibiotic resistance of incriminated bacteria over the last three years in the northern ***:From January 2007 to January 2010,533 cerebrospinal fluids(CSF) samples were collected from patients suspected of meningitis in the Regional Hospital of Dapaong(northern Togo).After microscopic examination,samples were cultured for bacterial identification and antibiotic susceptibility. Results:The study included 533 patients(306 male and 227 female) aged from 1 day to 55 years [average age(13.00±2.07) years].Bacterial isolation and identification were attempted for 254/533 (47.65%) *** bacteria]species identified were:Neisseria meningitidis A(*** A)(58.27%),Neisseria meningitidis W135(N,meningitidis W135)(7.09%),Streptococcus pneumoniae(***)(26.77%),Haemophilus influenza B(*** B)(6.30%) and Enterobacteriaceae(1.57%).The results indicated that bacterial meningitis occur from November to May with a peak in February for *** and *** and March for Neisseriaceae. The distribution of positive CSF with regards to the age showed that subjects between 6 and 12 years followed by subjects of 0 to 5 years were most affected with respective frequencies of 67.82%and 56.52%(P20%for both bacterial strains),macrolides(resistance rate>30%for ***) quinolones(resistance rate>15% for *** and *** W135).Over three years,the prevalence of *** significantly increased from 8.48%to 73.33%(P<0.001),while the changes in the prevalence of *** B were not statistically significant:4.24%,vs.8.89%,(P= 0.233).Conclusions: Our results indicate that data in African countries differ depending on geographical location in relation to the African meningitis *** underlines the impo
