This paper proposes a leakage detection method based on detecting significant discrepancies between pressure measurements and their estimations obtained from the simulation of calibrated water distribution network model. Every sensor in will allow to detect discrepancy due depending its location. Then, set well distributed sensors generate signature that allows localisation. presents methodology used Barcelona for distributing properly good discrimination localisation process. The placement...
To compare the predictive ability for neonatal acidemia of individual components intrapartum cardiotocography (CTG) described by National Institute Child Health and Human Development (NICHD) system deceleration area.Case-control study.Spanish tertiary obstetrical hospital.CTG patterns 102 acidemic fetus (umbilical arterial cord gas pH ≤7.10, base deficit (BD) > 8) nonacidemic controls 7.10).Two reviewers blind to clinical outcome data analyzed last thirty minutes before delivery 204 fetal...
<b>Objective</b> The objective of this study was to determine ability detect neonatal acidemia and interobserver agreement with the FIGO 3-tier 5-tier fetal heart rate (FHR) classification systems. <b>Design</b> This a case–control study. <b>Setting</b> set at University Medical Center. <b>Population</b> A total 202 FHR tracings 102 women who delivered an acidemic fetus (umbilical arterial cord gas pH ≤ 7.10 BE < − 8) 100 nonacidemic > 7.10) were assessed. subanalysis performed for those...
Raman scattering is used to study the phenomenon of spontaneous long-range ordering in ${\mathrm{GaInP}}_{2}$ epilayers. The measurements are performed a series single-variant ordered samples with different order parameter values. have been grown by metalorganic vapor phase epitaxy on GaAs (001) substrates misoriented 6\ifmmode^\circ\else\textdegree\fi{} off towards [111]B direction, and degree has varied changing growth temperature. selection rules derived, using group theory. Polarized...
We report a detailed investigation of the infrared and Raman activity ${\mathrm{AgGaSe}}_{2}$. Performing, first, studies in spectral range 15--500 ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$, both at room liquid-helium temperature, we could identify all ${\mathrm{\ensuremath{\Gamma}}}_{4}$ (E\ensuremath{\parallel}C ) ${\mathrm{\ensuremath{\Gamma}}}_{5}$ (E\ensuremath{\perp}C vibrational modes predicted by group-theory arguments. This includes, low energy, complete series folded-acoustic...
We report a cross investigation of the effect interdiffusion on photoluminescence and Raman spectra single quantum well InGaAs (80 Å wide) sandwiched between two large InGaAsP barriers. First, we investigate blue shift recombination line (2 K) after annealing at 650 750 °C from 15 min to 2 h. assume one diffusivity coefficient for all atomic species (i.e., conservation lattice matching annealing) deduce amount intermixing through model calculation. find average coefficients D=9.5×10−3 Å2 s−1...
We report on Raman scattering measurements Si-capped Ge quantum structures grown by molecular beam epitaxy Si(001) at low temperatures. find a double band structure in the Ge–Ge frequency range for nanoislands substrate temperatures ranging interval 300–500 °C. Complementary information has been obtained from performing experiments annealed samples. The results are interpreted terms of model that considers (hut clusters) composed strained core and more relaxed SiGe shell.
To determine which parameter of the umbilical arterial cord gas analysis, pH, base deficit (BD) or lactate has a bigger predictive ability for neonatal morbidity at term.We conducted four-year retrospective cohort study including all non-anomalous, singleton, vertex, term births with acidemia (umbilical pH ≤ 7.1). The primary outcomes were composite neurological and systemic morbidity. lactate, BD was compared using receiver operator characteristic (ROC) curves. Optimal cutoff values...
Background and Objectives: Fetal growth restriction (FGR) is a severe obstetric disease characterized by low fetal size entailing set of undesired consequences. For instance, previous studies have noticed worrisome association between FGR with an abnormal neurodevelopment. However, the precise link neurodevelopmental alterations are not yet fully understood yet. Brain-derived neurotrophic factor (BDNF) critical neurotrophin strongly implicated in other neurological processes. In addition,...
Currently, there is no validated treatment for fetal cytomegalovirus (CMV). Two studies suggest that high-dose maternal valacyclovir decreases viral load and improves outcomes in moderately-symptomatic fetuses. We offered cases of infection lacking ultrasound abnormalities or with non-severe infection. Maternal tolerability, outcome newborn blood were evaluated pregnancies mothers receiving valacyclovir.We performed a case series including 8 CMV classified as unaffected/mildly-moderately...
A Keating model calculation of phonon dispersion in CdGeAs2 with two bond stretching force constants between nearest neighbours and bending second is presented. The four parameters have been determined from a least mean square fit to our Raman data. In this study one emphasizes the relationship which connects zone centre modes phonons at Γ, X W points Brillouin associated zincblende materials: GaAs InAs, on hand, binary analog Ga0.5In0.5As, other hand. One shows that optical can be...
The division of a network in different sectors is usual practice Water Companies. It improves the management senses. Sectors have more homogenous characteristics and need specific cares treatments that not same all through network. Specifically for leakage detection assessment it interesting to know performance sector before any strategy applied. In this paper characterisation methodology presented. This based on knowledge provided by company but has been analysed using clustering...

Incidence features total number decelerations, slow return loss moderate variability during deceleration were extracted. estimated features, acidemia...
