A humidification system is described for use in neonatal ventilator treatment with the child placed in an incubator. By means of a temperature-controlled draw-over humidifier and a thermocouple in the inspiratory tube, it is possible to control the content of water vapour in the inspired gases and to calculate the humidity in percentage of the humidity in the lungs during controlled and spontan...

Hydration forces between DNA molecules in the A- and B-Form were studied using a newly developed technique enabling simultaneous in situ control of temperature and relative humidity. X-ray diffraction data were collected from oriented calf-thymus DNA fibers in the relative humidity range of 98%-70%, during which DNA undergoes the B- to A-form transition. Coexistence of both forms was observed o...

Melt crystallization of ibuprofen was studied to understand the effects of humidity and surfaces. The molecular self-assembly during the amorphous-to-crystal transformation was examined in terms of the nucleation and growth of the crystals. The crystallization was on Al, Au, and self-assembled monolayers with -CH(3), -OH, and -COOH functional groups. Effects of the humidity were studied at room...

Infrared radiative processes are implicated in Arctic warming and sea-ice decline. The infrared cloud radiative effect (CRE) at the surface is modulated by cloud properties; however, CRE also depends on humidity because clouds emit at wavelengths that are semi-transparent to greenhouse gases, most notably water vapour. Here we show how temperature and humidity control CRE through competing infl...

Mosquito-borne diseases particularly malaria is becoming most dreaded health problems in the Coastal Blocks of Ramanathapuram District, Tamilnadu, India. In Coastal Blocks of Ramanathapuram District, malaria is seasonal and unstable, causing frequent epidemics. For transmission of malaria parasite, climatic factors are important determinants such as rain fall, temperature relative humidity and ...

A self-consistent remote sensing physical method to retrieve atmospheric humidity high-resolution profiles by synergetic use of a microwave radiometer profiler (MWRP) and wind profiler radar (WPR) is illustrated. The proposed technique is based on the processing of WPR data for estimating the potential refractivity gradient profiles and their optimal combination with MWRP estimates of potential...

An algorithm to compute atmospheric humidity high-resolution profiles by synergetic use of Microwave Radiometer Profiler (MWRP) and Wind Profiler Radar (WPR) is illustrated. The focal point of the proposed technique is based on the processing of WPR data for estimating the potential refractivity gradient profiles and their optimal combination with MWRP estimates of potential temperature profile...

At northern latitudes a rise in atmospheric humidity and precipitation is predicted as a consequence of global climate change. We studied several growth and functional traits of hybrid aspen (Populus tremula L.×P. tremuloides Michx.) in response to elevated atmospheric humidity (on average 7% over the ambient level) in a free air experimental facility during three growing seasons (2008-2010) in...

"Observer based model predictive control of the water Based painting drying using a humidity profile soft sensor and a temperature measurement", This paper deals with the model predictive control of an infrared drying process of a water based epoxy-amine painting. During the drying cycle, the control problem is to optimize the use of the process under constraints. This approach is based on a no...
