There are a number of scenarios in which structural members experience torsion, including under the direct application torsional loading, when transverse loading is applied at an eccentricity to shear centre and as second order effect arising from lateral instability. To date, rigidity concrete-filled steel tubular (CFST) sections has yet be fully explored; hence study into uniform square CFST ...

It is widely accepted that the occupational therapy profession needs to incorporate research findings into clinical practice so as to improve client outcomes. The purpose of this study was to investigate the knowledge and attitudes toward evidence-based practice (EBP) of occupational therapy students in the Republic of Ireland. A validated questionnaire was used to survey the population of fina...

Several single-scan experiments for the measurement of the longitudinal relaxation time (T1) are proposed. These experiments result in fast and accurate determinations of the relaxation rate, are relatively robust to pulse imperfections, and preserve information about the chemical shift. The method used in these experiments is to first encode the T1 values as a spatial variation of the magnetiz...

Presented is a study of the tripping strength of asymmetrical longitudinal plate stiffeners subjected to a combination of axial and lateral loads. The loaded edges were taken to be simply supported. The method of analysis is based on the principle of minimum total potential, and ten displacement functions were used to describe the deformations of the plate and stiffeners. First yielding was use...

Ossification of the posterior longitudinal ligament (OPLL) is a rare cause of myelopathy in non-Oriental populations and relatively unrecognized by general practitioners. A case of an Afro-Brazilian 54-years-old woman presenting with tetraparesis due to cervical OPLL is presented. Emphasis is made for the inclusion of OPLL in the differential diagnosis of compressive cervical myelopathy.

A method is presented to partially transfer nuclear spin polarization from one isotope S to another isotope I by the way of heteronuclear spin couplings, while minimizing the loss of spin order to other degrees of freedom. The desired I spin polarization to be detected is a design parameter, while the sequence of pulses at the two Larmor frequencies is optimized to store the greatest unused S s...
