NURSING STANDARD PERINEAL WOUNDS commonly occur in women during labour (Albers et al 2005). A cross-sectional survey of 101 randomly selected NHS trusts in the UK in the mid-1990s revealed that 83% of low risk primigravidae experienced some form of perineal trauma (Williams et al 1998). Many women also experience labial tears, grazes or vulval varicosities which are painful (Steen 2007). Perine...
Desorption electrospray ionization mass spectrometry (DESI-MS) previously has been used to capture and identify transient intermediates in electrochemical redox reactions on a platinum-covered rotating waterwheel. We present here two different setups that use a flat surface with porous carbon tape as the working electrode, where analyte-containing microdroplets from the DESI probe contacted wit...
It has been clarified that deformation and annealing of martensite starting structure can produce ultrafine-grained structure in low carbon steel. This study aims to investigate the texture evolution and mechanical properties of samples with martensite structure deformed by two different forging processes. The martensitic steel samples were forged by plane strain compression and multi-directio...
Pasteurella multocida Heddleston serovar 3 and 4 strains share a common lipopolysaccharide 1 biosynthesis locus but display both interand intra-strain lipopolysaccharide heterogeneity. 2 3 Marina Harper, Frank St. Michael, Marietta John, Evgeny Vinogradov, Jennifer A. Steen, 4 Lieke van Dorsten, Jason A. Steen, Conny Turni, Patrick J Blackall, Ben Adler, Andrew 5 D. Cox and John D. Boyce 6 7 Au...
We report high-throughput growth of highly aligned single-walled carbon nanotube arrays on a-plane and r-plane sapphire substrates. This is achieved using chemical vapor deposition with ferritin as the catalyst. The nanotubes are aligned normal to the [0001] direction for growth on the a-plane sapphire. They are typically tens of micrometers long, with a narrow diameter distribution of 1.34 +/-...
The local response to an external magnetic field normal to the molecular plane of naphthalene and anthracene was investigated via current density and magnetic shielding density maps. The Biot-Savart law shows that the deshielding caused by pi-ring currents in naphthalene is stronger for alpha- than for beta-protons due to geometrical factors. The shielding tensor of the carbon nuclei in both mo...
In the title compound, C(18)H(19)BrN(2)O, the seven-membered azepine ring adopts a twist-boat conformation: the bond angles about the azepine N atom are indicative of sp(2) hybridization. The dihedral angle between the plane of the carbon-carbon double bond of the enone unit and the mean plane of the indole ring is 27.8 (1)°. In the crystal, an N-H⋯O hydrogen bond links the mol-ecules into chai...
