Understanding the effects of increasing temperature is central in explaining the effects of climate change on vegetation. Here, we investigate how warming affects vegetation regeneration and root biomass and if there is an interactive effect of warming with other environmental variables. We also examine if geothermal warming effects on vegetation regeneration and root biomass can be used in cli...

Since its introduction in 1940, the plaster of Paris block method of measuring soil moisture by means of electrical resistance (4) has been widely employed in agricultural fields. Hydrologic research2 (16), war production problems involving guayule culture (11, 12), and many other investigations ranging from field irrigation to greenhouse studies have made use of this technique. Briefly, the me...

rice is usually harvested at a high moisture content therefore it must be subjected to drying till the moisture below 14% and for longer storing till 12%. in this project a fixed laboratory dryer was selected for drying three varieties with three range of temperature 40, 50 and 60 c and two range of final moisture content 12% and 10% as completely randomized design. correlation of crack kernel ...

The drying behavior of green peas is investigated in a pilot scaled Fluidized Bed Dryer (FBD) with inert particles assisted by an Infra Red (IR) heat source. The variation of shrinkage and moisture diffusivity with temperature and moisture content were investigated. The experimental drying curves were adjusted to the diffusion model of Fick’s law for spherical particles. The result was that...

Survival of sclerotia of Sclerotinia minor and S. sclerotiorum was compared in irrigated fields during the summer in two major lettuce production areas in California. More than 50% sclerotia of S. sclerotiorum compared with 4 and 35% of S. minor remained viable after 24 weeks of burial at 15 and 5 cm depths, respectively, in the San Joaquin Valley while >80% of sclerotia survived in the Salinas...

Low temperature calorimetry (LTC) is usually applied to characterize the porosity of cement-based materials with a total water saturated state. By recording the heat flow of the sample at different testing temperatures, the ice content in the freezing and the melting process can be analyzed. In order to investigate the state of the water during the freezing/melting process of unsaturated porous...

in this research work, it was planned to study influences of hydrothermal treatment temperature, holding time and press temperature on wood density, spring back, moisture absorption as well as dimensional stability of combined-hydro-thermo-mechanically modified poplar wood. wood blocks were treated hydrothermally at temperatures 120, 150 and 180°c for holding time of 0, 30 and 90 min. afterward...
