These include ambient air temperature, relative humidity, type of cement used, and concentration of cement used.
Most experimental work has been devoted to identify the variables involved in depassivation: type of cement, water/cement (w/c) ratio, pore humidity, type of steel, etc. Present situation considers a comparative value, in general, of 0.4% by weight of cement.
Several factors influence NH3 emission, such as temperature, relative humidity, food type, moisture content, pH, wind speed, housing type, and substrate [54], [55].
These elements are solar radiation, temperature, humidity, precipitation (type, frequency, and amount), atmospheric pressure, and wind (speed and direction).
The removal rate of gaseous or aqueous contaminants is influenced by numerous parameters; UV light intensity, substrate concentration, O2 partial pressure, humidity, substrate type, and so on.
The tube outer diameters (0.3 3.6 μm), surface morphologies (pore size distribution: 20 200 nm) and tube wall thickness (50 500 nm) are controlled through tuning of the relative humidity, solvent type, and solution concentration (C/C*∼12).
Environmental variables among locations included marked differences in day and night temperatures, light intensity, day length, cloud cover, humidity, soil type, time of planting and coastal versus inland locations.
The finding of a geographic trend for higher endotoxin and data suggesting an effect of poor indoor temperature control, low humidity, and type of heating led us to consider if the local temperature range or amount of precipitation during the study year were related to endotoxin concentration in homes.
In this study we aimed to assess the epigenetic biodiversity, through cytosine methylation, within and between populations of wild emmer wheat using accessions collected from five geographically isolated regions with different climatic conditions such as: rainfall level, humidity, soil type and biotic conditions [ 23].
A resistance type humidity sensor has been fabricated from an assembly of CaCu3Ti4O12 thick film, Ag interdigitated electrodes, and an Al2O3 ceramic substrate.
Capacitive type humidity sensor has been fabricated in planar geometry of Al/TMBHPET/Al and its capacitance has been monitored as a function of relative humidity (RH) level at varied frequencies of ∼1 v AC input bias.
