The synapses related to the granule cells of the olfactory bulb of rat brain have been studied in aldehyde-fixed material. The synapses can be divided into three classes: (1) those which have asymmetrical synaptic membrane thickenings and spheroidal synaptic vesicles; (2) those with symmetrical synaptic thickenings and flattened vesicles; and (3) the reciprocal synapses, one half of which (from...

The course of asymmetrical or symmetrical go, no-go differentiation reversal was compared in 16 control and 16 septally lesioned dogs using two pairs of auditory stimuli (similar or dissimilar). The magnitude of impairment observed during the course of reversal in septal dogs was affected by the quality of discriminated stimuli, asymmetrical or symmetrical differentiation procedure and the exte...

This paper offers a typology that distinguishes between three types of customersupplier relationships, namely asymmetrical customer-dominated and supplierdominated relationships and more symmetrical relationships. A conceptual framework that identifies strategic relationship alternatives for small and medium-sized firms in asymmetrical relationships is presented, and the type of knowledge, lear...

By studying treatment contrasts and ANOVA models, we propose a generalized minimum aberration criterion for comparing asymmetrical fractional factorial designs. The criterion is independent of the choice of treatment contrasts and thus model-free. It works for symmetrical and asymmetrical designs, regular and nonregular designs. In particular, it reduces to the minimum aberration criterion for ...

Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) results in poor survival. The objective of the present study was to elucidate the impact of asymmetrical ground-glass opacity (GGO) and/or consolidation on outcomes in patients with AE-IPF. The cases of 59 consecutive patients with AE-IPF were retrospectively reviewed. High-resolution computed tomography (HRCT) at diagnosis of an AE...

BACKGROUND AND PURPOSE Associations between the site of brain injury and poststroke gait impairment are poorly understood. Temporal gait asymmetry after stroke is a salient index of gait dysfunction that has important functional consequences. The current study investigated whether subtraction lesion analysis could distinguish brain regions associated with persisting temporal gait asymmetry in c...

Flow fields around an oscillating circular cylinder are studied by solving the incompressible Navier-Stokes equations in primitive variable formulation. A finite volume method with a pressure predictor-corrector scheme is used and the solution procedure is accelerated by a local time stepping technique. Numerical tests are carried out at the Keulegan-Carpenter number KC < 20 and Reynolds number...

The concept of asymmetrical and symmetrical relationships is not one that has been well-defined in industrial marketing literature. Although various authors have pinned this title on relationships where there is an imbalance in one or a few characteristics, such as commitment, power or dependence (e.g. Gundlach, Achrol and Mentzer, 1995; Söllner, 1998), knowledge or initiation of change (Holmlu...

OBJECTIVE To assess the interaction of foot placement, trunk frontal position, weight-bearing and knee moment asymmetry at seat-off when rising from a chair. DESIGN Cross-sectional study. SUBJECTS Seventeen subjects with hemiparesis and 15 healthy controls. METHODS Trunk position, weight-bearing and knee moment asymmetry were quantified by kinetic and kinematic analysis when the subjects ...

BACKGROUND The use of three-dimensional (3D) surface imaging is becoming more popular and accepted in the fields of Medicine and Dentistry. The present study aims to develop a technique to automatically localise and quantify soft-tissue asymmetry in adults using 3D facial scans. This may be applied as a diagnostic tool to monitor growth and dynamic changes and to evaluate treatment outcomes. ...
