Hydrothermal Conditions

Pinus radiata wood was treated under hydrothermal conditions(steam) in an autoclave. The effect of temperature and time were studied. Bending strength, equilibrium moisture content, swelling and pH value of residual water were determined. Following effects were determined: a) a reduction of pH value, b) a considerable reduction of wooden mass, c) a reduction of equilibrium moisture up to 75% air humidity was registered. With higher air humidity no differences between treatments were detected, and d) with higher temperatures and longer treatment time, a reduction of bending strength was ascertained.

Image Position

The loss of moisture per pound of free moisture in a cheese is shown to depend on the moisture movement in the cheese and hence on a function of the group (diffusion rate × time/(height)2). The results of a series of experiments were correlated by means of the above expression. The variables correlated were time of storage, moisture content, fat content, air humidity, air temperature, size and shape of the cheese. Total moisture affects the free moisture value, and air humidity affects the free moisture via the equilibrium moisture. The main effect of temperature is on the rate of moisture diffusion, and the fat content also affects the rate of moisture diffusion. All experimental results for close-bodied cylindrical cheeses were approximately correlated by the expression.

The Impact

Asymmetric changes of day and night temperature have already been observed because of Climate Change. However, knowledge on environmental conditions either during day or night serving as trigger for growth processes is scarce. In this study, one rice (Oryza sativa) variety (IR64) was examined to assess the impact of varying temperatures and relative air humidities during day and night periods on biomass, leaf area, and dry matter partitioning between organs. Three different day and night temperature (30/20 °C, 25/25 °C, 20/30 °C) and relative air humidity (40/90%, 65/65%, 90/40%) regimes were established. The effect of relative air humidity on both plant dry matter and leaf area was larger than the effect of temperature, in particular low humidity had a strong negative impact during the night. With high day temperature, the shoot mass fraction increased, whereas the root mass fraction decreased. Specific leaf area increased at high night temperatures and led, along with the high leaf mass fraction at high night humidities, to higher growth rates. The results emphasize the importance of considering relative air humidity when focusing on plant responses to temperature, and strongly suggest that under asymmetric day and night temperature increases in the future, biomass partitioning rather than biomass itself will be affected.
