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...

Abstract This perspective paper summarizes the authors’ view on how process diagnostics and control can help to gain a deeper insight into thermal spray processes better understand underlying mechanisms. The current situation in terms of available strategies suitable sensors is described. In perspective, it assumed that with models, machine learning tools, will be possible perform smaller numbe...

Marcotted 'Persian' (Tahiti*) lime trees with severe magnesium deficiency were sprayed with magnesium nitrate at 3 concentrations (1.75, 3.50, and 5.25 pounds of MgO/100 gallons of water). Three applications were made between March and September, 1967. Most of the magne sium deficiency symptoms disappeared after 2 sprays. The trees were completely green after the third spray, regardless of the ...

In this paper, we develop an economically optimizing Nonlinear Model Predictive Controller (E-NMPC) for a complete spray drying plant with multiple stages. In the E-NMPC the initial state is estimated by an extended Kalman Filter (EKF) with noise covariances estimated by an autocovariance least squares method (ALS). We present a model for the spray drying plant and use this model for simulation...

biological control of root-knot nematode meloidogyne javanica by application of pseudomonas fluorescens cha0 was evaluated under greenhouse condition. results showed that p. fluorescens (109 cfuml-1) as shoot spray significantly reduced in no. of eggmass and egg per individual eggmass as comparison to control. application p. fluorescens as shoot spray induced systemic activation of peroxidase (...

The Bioko Island Malaria Control Project (BIMCP) has carried out intensive interventions since early 2004 to reduce malaria transmission through indoor residual spraying (IRS) and case management. Annual parasite prevalence surveys have been carried out to monitor the effectiveness of the program. Significant overall reductions in prevalence of infection have been observed, with 42% fewer infec...

We have compared four methods of topical anaesthesia of the nostril for fibreoptic airway endoscopy in a randomized study with 31 unpremedicated volunteers, each serving as his or her own control. Lignocaine spray, EMLA cream, three cotton swabs soaked in 4% lignocaine solution, or 2% lignocaine gel was applied in a nostril for 3 min. Application of lignocaine spray was rated as the most unplea...

The purpose of the study was to evaluate the influence of Fluori-Methane spray as a method of affecting passive range of motion measured at the right hip joint. Subjects were 30 normal volunteers randomly divided into an experimental group and a control group. A special table was constructed to position and stabilize each subject for monitoring the right lower extremity's resistance to side-lyi...

Two field trials in leek were set up to determine and, if possible, improve the effect of spray applications of Steinernema feltiae (Filipjev) Wouts, Mracek, Gerdin et Bedding against Thrips tabaci Lindeman. The first trial focused on selecting a suitable application technique and on testing the effect of an attractant on thrips control in leek. The second trial focused on incorporating entomop...
