Environmental health policy decisions are characterized by irreversibility and uncertainty of an economic, ecological and biomedical nature. For this reason decision-makers may choose to exercise when possible some discretion over the timing and scope of policy. Problems of this kind fall within the framework of the theory of irreversible investments as applied to the sunk costs and sunk bene t...

Air pollution, especially airborne particulate matter, is becoming a major problem in Chiang Mai. The present study reports findings on total suspended particulate matter (TSP) loading as well as its spatial and daily variation in Chiang Mai ambient air. Limited elemental analysis of airborne particulate matter was also performed. Samples were collected at four different sites, representative o...

Tool health monitoring (THM) is in great focus nowadays from the perspective of predictive maintenance. It prevents increased downtime due to breakdown maintenance, resulting reduced production cost. The paper provides a novel approach tool computer numeric control (CNC) machine for turning process using airborne acoustic emission (AE) and convolutional neural networks (CNN). Three different wo...

Hospitalized patients have a potential risk for nosocomial infections. Airborne fungi are one of the main causes of fungal infections in this group. The objective of this study was to investigate the concentrations and species of airborne fungi in two general hospitals in Shiraz, southern Iran. Air samples were collected from high-risk wards, using settle plate method. Fungal colonies were iden...
