Journal: :Powder Technology 2021

Thirty-six food powders corresponding to a wide range of physicochemical characteristics (bulk and surface chemical composition, median particle size, span, water activity) manufacturing processes (grinding, freeze-drying, spray-drying, crystallization) were investigated for their reconstitutability. Their reconstitution profiles acquired by conductivity measurements fitted with Hill model. Phy...

BACKGROUND AND AIMS This study explores basic physiological features and time relations of recovery of photosynthetic activity and CO(2) uptake following rehydration of a desiccation-tolerant moss in relation to the full temporal sequence of cytological changes associated with recovery to the normal hydrated state. It seeks reconciliation of the apparently conflicting published physiological an...

Wetting and drying cycles are widely recognised as driving aquatic macroinvertebrate zooplankton production, providing prey recruitment opportunities for fish in floodplain river systems. Conversely, invertebrate consumption of fishes features less frequently food web studies. We used two sources information: a) the finding an intact eel skeleton exceedingly high number diving beetles (Cybister...

Moisture sorption can significantly influence hydrothermal ageing and alter the chemical rheological properties of bituminous mastics. Mineral filler particles are added to binders form mastics with increased stiffness. The addition fillers considerably change moisture physico-chemical by surface interactions physical presence. This study aims investigate effect type on moisture-induced changes...

Natural fibre-reinforced cementitious composites are commonly used as outer construction materials. They usually suffer weather a result of being expose to various types climates. In this study, series experimental tests were carried out investigate the deterioration mechanism and mechanical properties mortars incorporating coconut fibres due repeated wetting drying. The results indicated that ...

Due to high swelling-shrinkage caused by climate change, expansive soil is a significant problem in light construction, road embankments, and slope stability (wet dry). The physical mechanical properties of the are affected repeated drying wetting cycles, particularly changes volume, negative pore water pressure (suction), compressive strength. Fly ash used increase strength reduce plasticity s...

Recent wetting in the Northern Great Plain (NGP) exerted strong influences on lakes and wetlands. However, influence of recent increase precipitation spatiotemporal variation surface water area is poorly understood Red River Basin (RRB, northern United States southern Canada). Here, we used a high-resolution global dataset to understand dynamics annual, total, permanent, seasonal extent RRB. Mo...

Managed aquifer recharge is an efficient approach using surface water for groundwater recharge. However, soil clogging in the infiltration systems represents a critical problem that reduces efficiency of systems. In recent years, much research has been conducted to investigate subsurface and (cake). Cake prevents into table can drastically reduce rate. arid semi-arid areas, alternation humid dr...
