The performance evaluation of Mixed-Mode Passive Solar Dryer for drying codfish (Gadusmorhua) was conducted. dryer is comprised among other things, materials sensible heat storage to discharge during the off-sunshine period. chamber integrated with a suction device aid convective airflow avoid reversible reaction accumulated moisture. solar evaluated fresh samples at initial moisture content 79...

During the interplanetary flights the crewmembers will be exposed to cosmic ray radiation with great risk for their health. The absorbed dose due to CR depends on the galactic (GCR) or solar (SCR) origin. GCRs are isotropic and relatively high in energy and deliver a dose nearly constant with time that can be reduced only by means of "heavy" passive protection. The outer walls of the spacecraft...

Worldwide, buildings have been presented as one of the main energy consumers and, for that matter, there is an increased tendency to invest in policies and measures promote more efficient buildings. Among chosen strategies, need use passive solutions retrofit existing building stock often pointed out. Portuguese has proven be obsolete terms thermal comfort, which can directly affect demand clim...

Integration of phase-change materials (PCMs) into building fabrics is considered to be one of the potential and effective ways of minimising energy-consumption and CO2-emissions in the building sector. In order to assess the thermal effectiveness of this concept, composite PCM drywall samples (i.e., randomly mixed and laminated PCM drywalls) have been evaluated in a model passive-solar building...
