In the present study the ergonomic conditions of manual spray painting in the woodworking industry have been studied. Manual spray painting is, despite rationalisations, quite common in the Swedish woodworking industry. Interviews with spray painters showed that they had higher prevalence of musculoskeletal symptoms in their right shoulder compared with other workers with manual work. A majorit...

The Coastal Aerosol Transport (CAT) model was developed to study the evolution of aerosol particle size distributions and composition in the coastal environment. The model simulates such processes as particle production at the sea surface, mixing of particles through the boundary layer by turbulent diffusion, gravitational settling, and dry deposition. The model is initialized at the shoreline ...

1) Hydraulic Analysis of the Emergency Core Spray System in a BWR The emergency spray system of a BWR delivers cold water to the core after a large-break loss of coolant accident has emptied the reactor vessel. The system comprises a large water pool, a pump, a spray nozzle and connecting pipes (Figure 1). All pipes are smooth round tubes made of stainless steel with 10 cm internal diameter. Th...

Encapsulation technique via spray drying can be employed to enhance the natural pigment’s properties. In this study, spray-dried microparticles containing red pigment (prodigiosin) extracted from Serratia marcescens was produced using κcarrageenan and maltodextrin as encapsulation agents. The effect of spray-drying parameters on the encapsulation yield (EY), particle size and color intensity of...

in order to study the effect of ca, k, and mn foliar spray on vegetative traits of safflower (padideh cultivar) under salt stress, a factorial experiment was conducted based on randomized complete blocks design with three replications in vali-asr university greenhouse. factors included salinity with four levels representing 0, 500, 1000, and 1500 mg nacl kg -1, and foliar spray with four level ...

to study the effects of urea foliar spray at different plant growth stages on grain yield and protein percentage of two dryland wheat varieties of sardari and azar 2, an experiment was conducted in east mangor agricultural station of mahabad in 2007– 2008. the experiment design was split plot based on randomized complete block design with three replications. treatments were 50 gr×10 m-2 n as ur...

Azelastine nasal spray (Allergodil((R)), Lastin((R)), Afluon((R)); Meda AB, Stockholm, Sweden) is a fast-acting, efficacious and well-tolerated H1-receptor antagonist for the treatment of rhinitis. In addition it also has mast-cell stabilizing and anti-inflammatory properties, reducing the concentration of leukotrienes, kinins and platelet activating factor in vitro and in vivo, as well as infl...

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 ...

Considering prolongation of a Lie algebroid equipped with a spray, defining some classical tensors, we show that a Lie symmetry of a spray is a curvature collineation for these tensors.
