Here, we show that alpine lake ecosystems are responsive to interannual variation in climate, based on long-term limnological and meteorological data from the Canadian Rockies. In the 2000s, in years with colder winter temperatures, higher winter snowfall, later snowmelt, shorter ice-free seasons, and dryer summers, relative to the 1990s, alpine lakes became clearer, warmer, and mixed to deeper...

Hebel brick is used in making the walls of house. One materials hebel bricks sand. The water content sand will affect quality bricks. less sand, better In order to get with a little content, it necessary do drying process. To overcome this problem, rotary dryer for using renewable energy, particular biomass energy sources was designed. It can be placed quarry near river or beach. designed have ...

This article deals with the integration of a rotary indirect dryer, heated by low pressure extraction steam, into Rankine cycle. The evaluates power generation efficiency steam plant, an integrated which combusts waste biomass high moisture content and is further compared to same plant without dryer. benefits dryer’s are analysed in respect various contents before after drying. evaluation based...

Application of tray dryer is widely used in agricultural drying because of its simple design and capability to dry products at high volume. However, the greatest drawback of the tray dryer is uneven drying because of poor airflow distribution in the drying chamber. Implementing the proper design of a tray dryer system may eliminate or reduce non-uniformity of drying and increases dryer efficien...

Performance of a tractor mounted solar-biomass hybrid dryer which utilise combined energy solar and biomass was investigated. Drying behaviour maize grains in the also investigated using 10 thin-layer mathematical models. The models were compared based on coefficient determination (R2) root mean square error (RMSE) values between experimental predicted moisture ratios. Moisture content (MC) red...

The purpose of this study was to determine the performance a hybrid dryer by combining utilization solar energy (solar dryer) and biomass power sources. Utilization thermal sources maximizing heat radiation which are absorbed directly into drying chamber in form transparent house with ventilation holes for fresh air enter moist exit. This process will produce hot circulation (convection) contin...

The unpredictable rise and frequent scarcity of fossil fuel accelerated the continuous search for an alternative power source. Solar is one of the renewable and sustainable sources of power that attracted a large community of researchers from all over the world. This is largely due to its abundant in both direct and indirect form. As such the development of efficient and inexpensive equipment f...

An experimental methodology was developed to improve the energy design of paddle dryers for sewage sludges. A laboratory batch dryer with a vertical agitator has been especially designed and instrumented to determine the heat flux densities. To determine the drying kinetic and the evaporating flow rates, the specific heat and the total heat of desorption of the sludge were measured using calori...
