The surface chemical properties and the electronic of vapor grown carbon nanofibers (VGCNFs) have been modified by treatment oxidized CNFs with NH(3). effect temperature on types nitrogen functionalities introduced was evaluated synchrotron based X-ray photoelectron spectroscopy (XPS), while impact preparation methods acid-base investigated potentiometric titration, microcalorimetry, zeta potential measurements. N-functionalization measured THz-Time Domain spectroscopy. samples...
In the applications one is given matrix A and it required to construct P(t) study properties of corresponding stochastic process. The existence, uniqueness, analytic have been discussed in detail [I]. objective this paper use results [1] establish equivalences between process sequences { Xn }, n,u } evaluate, terms these sequences, some interesting probabilistic quantities associated with
~ (λt + [h)t o(t) if j = i where Xt > 0 for 0, μt 1 and μ0 0. We further assume that Pu(ί) satisfies the foward backward equation in usual form. In this paper we restrict attention to case — so when particle enters state zero it remains there a random length of time according an exponential distribution with parameter λ0 then moves into one etc. order avoid inessential difficulties henceforth infinitesimal birth death rates μi uniquely determine process. This is equivalent condition Σ~-o (πn...
<h3>Abstract</h3> <b>Objectives</b>: To investigate the possible spread of HIV infection and its route transmission among prison inmates. <b>Design</b>: In response to an outbreak acute clinical hepatitis B two seroconversions infection, counselling testing for were offered all inmates over a week period in July 1993. Information was sought about drug injecting, sexual behaviour, previous testing. <b>Setting</b>: HM Prison Glenochil Scotland. <b>Subjects</b>: Adult male prisoners. <b>Main...
OBJECTIVE: To study how frequency, recentness, and reason for douching impact bacterial vaginosis-related vaginal microflora the occurrence of cervical pathogens. Douching has been linked to vaginosis as well chlamydial cervicitis in some, but not all, studies. METHODS: A total 1200 women at high risk sexually transmitted infections were enrolled from five clinical sites around United States. Cross-sectional, structured interviews conducted swabs self-obtained Gram stain, culture, DNA...
In the Ehrenfest model with continuous time one considers two urns and N balls distributed in urns. The system is said to be state i if there are urn I, − II. Events occur at random times intervals T between successive events independent variables all same negative exponential distribution When an event occurs a ball chosen (each of has probability 1/ chosen), removed from its urn, then placed I p , II q = 1 (0 < 1).

The liquid state structure of the ionic liquid, 1-ethyl-3-methylimidazolium acetate ([C(2)mim][OAc]), an excellent nonderivitizing solvent for cellulosic biomass, has been investigated at 323 K by molecular dynamics (MD) simulation and neutron diffraction using SANDALS diffractometer ISIS to provide experimental differential scattering cross sections from H/D isotopically substituted materials. Ion-ion radial distribution functions both calculated MD derived empirical potential refinement...
Terahertz and PFG-NMR techniques are used to explore transitions in the structuring of binary alcohol/water mixtures. Three critical alcohol mole fractions (x1, x2, x3) identified: methanol (10, 30, 70 mol %), ethanol (7, 15, 60 1-propanol (2, 10, 50 2-propanol %). Above compositions x1 no isolated molecules exist, below formation large hydration shells around hydrophobic moieties is favored. The maximum number water molecules, N0, shell surrounding a single molecule increases with length...
