This paper describes a new video-based observation method aimed to assess musculoskeletal load in kitchen work, aspects of its repeatability and validity, and problems confronted by the observers. Two pairs of researchers observed individually 117 video clips recorded in kitchens. Interobserver repeatability was assessed by computing the proportion of agreement and weighted kappa values (kappa(...

Abstract In the present paper, we study invariant submanifolds of almost Kenmotsu structures whose Riemannian curvature tensor has $$(\kappa ,\mu ,\nu )$$ ( ? , ? ? ) -nullity distribution. Since geomet...

We derive the current-voltage relationship in the auroral region taking into account magnetospheric electrons for the bi-Maxwellian and kappa source plasma distribution functions. The current-voltage formulas have in principle been well known for a long time, but the kappa energy ̄ux formulas have not appeared in the literature before. We give a uni®ed treatment of the bi-Maxwellian and kappa d...

The development of methods for engineering proteins with novel properties opens the way to manipulating intracellular processes in a therapeutically useful way. Glucocorticoids, acting via glucocorticoid receptors (GR), are potent anti-inflammatory agents, acting to oppose nuclear factor kappa B (NF kappa B) function. The herpes viral protein, VP22, has been reported to confer intercellular tra...

The imported Harmonia axyridis ladybug infests homes in northern West Virginia from fall through spring, causing allergic disease. Retrospective single-practice chart reviews were performed: (1) all skin prick tests (1400 included ladybug) in a community allergy practice over 4 years and (2) clinical analysis of 400 randomly chosen patients. The usual adult aeroallergen skin test panel included...

OBJECTIVE To measure agreement between nine structured approaches for diagnosing childhood tuberculosis; to quantify differences in the number of tuberculosis cases diagnosed with the different approaches, and to determine the distribution of cases in different categories of diagnostic certainty. METHODS We investigated 1445 children aged < 2 years during a vaccine trial (2001-2006) in a rura...

BACKGROUND Patient evaluations are widely used in quality assessment of health services. It is widely recognized that patients and professionals provide a different perspective on quality. However, the extent to which they differ and the conceptual areas in which they differ is not well understood. OBJECTIVES We sought to examine how well professional and patient assessments of hospital healt...
