Gravitational stability of torsion and inflaton field in a four-dimensional spacetime de Sitter solution in scalar-tensor cosmology where Cartan torsion propagates is investigated in detail. Inflaton and torsion evolution equations are derived by making use of a Lagrangean method. Stable and unstable modes for torsion and inflatons are found to be dependent of the background torsion and inflato...

objectives: low back pain is one of the main health problems which affect many people worldwide. the daily course of life is highly disrupted due to the chronic back pain problem. this study aims to explore the occupational performance of individuals with chronic low back pain. methods: fifteen people with chronic low back pain were included in this study using purposeful sampling. the particip...

The origin of quantum interference characteristic of bound nonlinear systems is investigated within the Bohmian formulation of time-dependent quantum mechanics. By contrast to time-dependent semiclassical theory, whereby interference is a consequence of phase mismatch between distinct classical trajectories, the Bohmian, fully quantum mechanical expression for expectation values has a quasiclas...

The distribution of immunoreactive catecholamine neurons and fibers was investigated in brindled mottled mouse, a murine model of Kinky hair syndrome (KHS), using antisera against tyrosine hydroxylase (TH) and dopamine-beta-hydroxylase (DBH). In all mice, including normal littermate controls, a transient increase of TH-immunoreactive neurons (TH-IN) was observed in the cerebral cortex during th...

Prior research has documented a ‘‘kink’’ in the earnings distribution: too few firms report small losses, too many firms report small profits. We investigate whether boosting of discretionary accruals to report a small profit is a reasonable explanation for this ‘‘kink.’’ Overall, we are unable to confirm that boosting of discretionary accruals is the key driver of the kink. We caution the use ...

background: chronic non-specific low back pain is a common disorder that often has no clear mechanism. exercise therapy is an effective and safe method for treatment of chronic musculoskeletal disorders such as back pain. pilate’s and williams’ exercises are two types of distinct exercises used for the treatment of back pain, but there is no evidence for the advantage of these two exercises in ...

INTRODUCTION Many risk factors have been identified for chronic low back pain (cLBP), but only one study evaluated their interrelations. We aimed to investigate the frequency of cLBP risk factors and their interrelations in patients consulting their general practitioners (GPs) for cLBP. METHODS A cross-sectional, descriptive, national survey was performed. 3000 GPs randomly selected were aske...

STUDY DESIGN A prospective cohort study within care as usual. OBJECTIVE (1) To explore the psychometric properties of a baseline disability questionnaire designed to collect patients' expectation. (2) To analyze relations between satisfaction with care and treatment success in patients with chronic low back pain (CLBP). (3) To determine the chances of being satisfied with the received care in...
