We investigate the dynamics of fracture in drying films of colloidal silica. Water loss quenches the nanoparticle dispersions to form a liquid-saturated elastic network of particles that relieves drying-induced strain by cracking. These cracks display intriguing intermittent motion originating from the deformation of arrested crack tips and aging of the elastic network. The dynamics of a single...

ABSTRACT Grain drying is a common process, due to its need for the maintenance of quality, but it activity with highest energy demand among postharvest stages. Thus, this study aimed evaluate effect different tempering times on efficiency process and cell membrane integrity maize grains harvested moisture content at 0.34 ± 0.01 d.b. The were dried in an experimental fixed-bed dryer control temp...

the prevalent method of irrigation in paddy fields in iran is continuous ponding, which changes to intermittent method at the time of water shortage. soil cracks are the main problem in intermittent irrigation. in this study, effects of adding rice straw on some soil physical characteristics and cracks were studied in paddy soils of the guilan province of iran. the experiment was performed as s...

To improve bacterial removal, a traditional stormwater biofilter can be augmented with biochar, but it is unknown whether bacterial removal remains consistent as the biochar weathers during intermittent exposure to stormwater under dry-wet and freeze-thaw cycles. To examine the effect of weathering on bacterial removal capacity of biochar, we subjected biochar-augmented sand filters (or simplif...

The novelty of this paper was to evaluation the effect intermittent microwave drying (IMD) on nutritional quality and characteristics persimmon slices. Persimmon slices were treated with IMD at power levels 280, 350, 420, 490, 560 W, characteristics, components, sensory properties determined analyzed. results showed that process could be divided into three stages; increasing speed, constant dec...

Intermittent microwave drying improves the quality of dehydrated product, because reduces effect hot spots. Mathematical modelling is essential to understand physics this process and optimize operation conditions. However, there are few studies about intermittent drying. This work proposed a mathematical model based on mass balances liquid vapor water in which non-equilibrium formulation descri...

More freshwater ecosystems are drying in response to global change thereby posing serious threat to freshwater biota and functions. The production of desiccation-resistant forms is an important adaptation that helps maintain biodiversity in temporary freshwaters by buffering communities from drying, but its potential to mitigate the negative effects of drying in freshwater ecosystems could vary...

In this study, response surface methodology was used for optimization of intermittent microwave-convective air drying (IMWC) parameters with employing desirability function. Optimization factors were air temperature (40-80°C), air velocity (1-2 m/sec), pulse ratio) PR ((2-6), and microwave power (200-600 W) while responses were rehydration ratio, bulk density, total phenol content (TPC), color ...
