objectives to compare an out-of-plane interscalene catheter technique to the in-plane technique in a randomized clinical trial. patients and methods eighty-four patients undergoing open shoulder surgery were randomized to either the in-plane or out-of-plane ultrasound-guided continuous interscalene technique. the primary outcome was vas pain rating at 24 hours. secondary outcomes included pain ...

Comparative studies lasting between 59 - 63 days were carried out using the N-balance method to investigate effect of groundnut cake supplementation on N-metabolism and digestible crude protein (DCP)requirements three breeds steers maintained all-roughage rations hay fresh dry Cynodon rulenfuensis var robustus The results indicated that N intake (/day) Increased ed appreciably with supplementat...

Physical phase plates (PP) for transmission electron microscopy (TEM) are intensively studied since the first carbon film-based and electrostatic PPs have been experimentally realized [1,2]. By inducing a phase shift on a part of the electrons in the back focal plane of the objective lens, contrast enhancement can be achieved. Several groups have already demonstrated proof-of-principle experime...

We report a multi-wavelength Raman spectroscopy study of the structural changes along the thermal annealing pathway of a poly(furfuryl alcohol) (PFA) derived nanoporous carbon (NPC). The Raman spectra were deconvoluted utilizing G, D, D’, A and TPA bands. The appropriateness of these deconvolutions was confirmed via recovery of the correct dispersive behaviours of these bands. It is proposed th...

The Clar number of a (hydro)carbon molecule, introduced by Clar [E. Clar, The aromatic sextet, (1972).], is the maximum number of mutually disjoint resonant hexagons in the molecule. Calculating the Clar number can be formulated as an optimization problem on 2-connected planar graphs. Namely, it is the maximum number of mutually disjoint even faces a perfect matching can simultaneously alternat...

background and aims. orientation of the occlusal plane is one of the most important clinical procedures in prosthodontic rehabilitation of edentulous patients. the aim of this study was to define the best posterior reference point of ala-tragus line for orientation of occlusal plane for complete denture fabrication. materials and methods. fifty-three dental students (27 females and 26 males) wi...

Magnesium (Mg) is the most commonly used acceptor dopant in gallium nitride (GaN) devices. Acting as a deep acceptor with an activation energy of ~ 200 meV, Mg can introduce electrical and optical complications. Carbon has been demonstrated to be a possible alternative acceptor dopant atom with a lower activation energy [1]. Carbon-doped GaN (GaN:C) samples were homoepitaxially grown on <10-11>...

Edged plane pyrolytic graphite electrode (EPPGE) was modified with and without Prussian blue (PB) nanoparticles and polyaminobenzene sulphonated single-walled carbon nanotubes (SWCNTPABS) using the chemical deposition method. The electrodes were characterised using microscopy, spectroscopy and electrochemical techniques. Results showed that edged plane pyrolytic graphite-single-walled carbon na...

The structure of the title compound, C(19)H(17)BrN(2)O(3), consists of two cyclic groups, viz. 4-(meth-oxy-carbon-yl)phenyl and 6-(4-bromo-phen-yl)-3-oxo-2,3,4,5-dihydro-pyridazin-4-yl, which are linked by a methyl-ene spacer. The pyridazine ring is twisted and the dihedral angle between its mean plane and that of the bromo-phenyl mean plane is 17.2 (2)°. The 4-(meth-oxy-carbon-yl)phenyl group ...
