PURPOSE to evaluate the correlation between the estimated fetal weight (EFW) by ultrasonography and the neonatal weight (NW), as well as the EFW's capacity to predict changes in NW among pregnant women in João Pessoa, Paraíba, Brazil. METHODS a diagnostic validation study, including 122 pregnant women who have had the EFW calculated by ultrasonography up to seven days before delivery and the ...

Detection of respiratory viruses by real-time multiplexed PCR (M-PCR) and of respiratory syncytial virus (RSV) by M-PCR and immunofluorescence (IF) was evaluated using specimens collected by nasopharyngeal flocked swabbing (NFS) and nasal washes (NW). In children with mild respiratory illness, NFS collection was superior to NW collection for detection of viruses by M-PCR (sensitivity, 89.6% ver...

Nesting of relations is very much essential for many database representations in reality. Nesting of relations tends to reduce the data redundancy in the relations. It helps in dropping certain constraints in normalization which tend to omit certain sensitive data when tried to be normalized. Query processing or conversion of data repositories, as required, can be easily being tackled by the ai...

Large strain-energy arising from lattice mismatch allows one-dimensional heteroepitaxial growth of InxGa1−xAs on silicon substrates without any catalyst or pattern assistance. In this paper, we show that in contrast to nanowires (NWs) grown by metal-catalyzed vapor−liquid− solid mechanism, strain-induced InxGa1−xAs NWs have several unique morphological features including no tapering, slight ben...

Fast and accurate relative positioning for baselines less than 20 km in length is possible using dual-frequency Global Positioning System (GPS) receivers. By measuring orthometric heights of a few GPS stations by di€erential levelling techniques, the geoid undulation can be modelled, which enables GPS to be used for orthometric height determination in a much faster and more economical way than ...

Nanowire field effect transistors (NW-FETs) can serve as ultrasensitive detectors for label-free reagents. The NW-FET sensing mechanism assumes a controlled modification in the local channel electric field created by the binding of charged molecules to the nanowire surface. Careful control of the solution Debye length is critical for unambiguous selective detection of macromolecules. Here we sh...

Gujarat in the Northwestern Deccan Volcanic Province of India is among most seismically earthquake-prone. The region may be susceptible to remote dynamic triggering, especially Kachchh region, which recently hosted M w 7.7 Bhuj earthquake 2001. Its aftershocks continue because it critically stressed and contains nucleation points more frequently close failure. From waveforms catalog data, we ex...

Following the end-Permian mass extinction, ammonoids were among the fastest clades to recover (Brayard et al., 2006), with at least two diversification phases during the Early Triassic. Diversification first peaked during the Smithian and was followed by a marked extinction phase at the end of this (sub-)stage. It was then followed by a second and massive evolutionary radiation during the Spath...

Branched nanostructures represent unique, 3D building blocks for the "bottom-up" paradigm of nanoscale science and technology. Here, we report a rational, multistep approach toward the general synthesis of 3D branched nanowire (NW) heterostructures. Single-crystalline semiconductor, including groups IV, III-V, and II-VI, and metal branches have been selectively grown on core or core/shell NW ba...

There has been tremendous interest and progress with synthesis of inorganic nanowires (NWs). However, much of the progress only resulted in NWs with diameters much greater than their respective quantum confinement scales, i.e. 10–100 nm. Even at this scale, NW-based materials offer enhanced charge transport and smaller diffusion length scales for improved performance with various electrochemica...
