Scientific Research in the Saw-Mill Industry

A comparative study of lung functions in rice mill and saw mill workers.

A lung function study was carried out to determine the relative effect of rice husk and saw dust on mill workers. The study consisted of 195 subjects of which 56 rice mill workers, 71 saw mill workers and 68 controls of similar age, sex and socio-economic condition. FVC was significantly reduced in saw-mill workers compared to both the controls and rice mill workers. Both FEV1 and PEFR/min were...

Pulmonary function tests in saw mill factory workers.

The prevalence of pneumoconiosis varies from 15–30% in various parts of India (1). Occupational asthma may account for about 10% of adult asthma (2). Asthma associated with work is being recognized with increased f requency in carpenters , saw mi l l workers and furn i tu re makers . The cause for occupa t iona l as thma i s wood/saw dus t .

SAW dispersion

Nondestructive evaluation of the prevailing compressive residual stress in the shallow subsurface layer of surface-treated metals is greatly complicated by the accompanying surface roughness and cold work. A high-precision laser-ultrasonic technique has been developed to study the feasibility of SAW dispersion spectroscopy for residual stress assessment on surface-treated metals in a wide frequ...
