BACKGROUND Untreated immunization pain causes undue distress and contributes to underimmunization through physician, and possibly parental, resistance to multiple simultaneous injections. OBJECTIVE To compare the efficacies of two pain management methods in reducing immediate immunization injection pain and distress in school-aged children. DESIGN A randomized, controlled clinical trial of ...
This paper is concerned with aspects of gasoline spray droplet impingement simulation, for which an improved model has been developed for predicting the outcomes of spray droplets impacting on a wall. The model is assessed by simulating experiments on oblique spray impingement in a wind tunnel. This is done with the aid of a specially-devised procedure for deducing the specification of initial ...
INTRODUCTION ABSTRACT Particle depositional studies from nasal sprays are important for efficient drug delivery. The main influences on deposition involve the nasal cavity geometry and the nasal spray device of which its parameters are controlled by the product design. It is known that larger particle sizes (>>10μm) at a flow rate of 333 ml/s impact in the anterior portion of the nose, leaving ...
