In hot weather, humidity content affects adversely the human body. It causes body fatigue and slowness in metabolism by excessive sweating and increased body temperature. If the relative humidity rate is 100% , there won't be sweating and the body temperature will rise. The rise in body temperature can lead people to death. Moreover, high amounts of CO2 in the air accelerate fatigue. Reach of i...

In this paper, we investigated the effect of humidity on paper substrates and propose a simple and low-cost method for their passivation using ZnO nanoparticles. To this end, we built paper-based microdevices based on an interdigitated electrode (IDE) configuration by means of a mask-less laser patterning method on simple commercial printing papers. Initial resistive measurements indicate that ...

This study is an investigation of high-humidity aging effects on the total volatile organic compound (T-VOC) gas-sensing properties of platinum, palladium, and gold-loaded tin oxide (Pt,Pd,Au/SnO(2)) thick films. The sensor responses of the high-humidity aged Pt,Pd,Au/SnO(2), a non-aged Pt,Pd,Au/SnO(2), and a high-humidity aged Pt/SnO(2) to T-VOC test gas have been measured. The high-humidity a...

Online monitoring humidity in the proton exchange membrane (PEM) fuel cell is an important issue in maintaining proper membrane humidity. The cost and size of existing sensors for monitoring humidity are prohibitive for online measurements. Online prediction of humidity using readily available measured data would be beneficial to water management. In this paper, a novel soft sensor method based...

Microclimate variables such as air temperature and relative humidity influence habitat conditions and ecological processes in riparian forests. The increased relative humidity levels within riparian areas are essential for many plant and wildlife species. Information about relative humidity patterns within riparian areas and adjacent uplands are necessary for the prescription of effective buffe...

We tested the effects of high humidity and submergence on egg hatching of spider mites. In both the high humidity and submergence treatments, many Tetranychus and Panonychus eggs did not hatch until after the hatching peak of the lower humidity or unsubmerged controls. However, after humidity decreased or water was drained, many eggs hatched within 1-3 h. This was observed regardless of when hi...

BACKGROUND The role of relative humidity in the aerosol transmission of influenza was examined in a simulated examination room containing coughing and breathing manikins. METHODS Nebulized influenza was coughed into the examination room and Bioaerosol samplers collected size-fractionated aerosols (<1 µM, 1-4 µM, and >4 µM aerodynamic diameters) adjacent to the breathing manikin's mouth and al...
