Relative to solar water heaters, solar air heaters have received relatively little investigation and have resulted in few commercial products. However, in the context of a humidification-dehumidification (HDH) desalination cycle, air heating accounts for advantages in cycle performance. Solar collectors can be over 40% of an air-heated HDH system’s cost; thus, design optimization is crucial. Be...

This study investigated how a honey bee colony develops and quenches its collective thirst when it experiences hyperthermia of its broodnest. We found that a colony must strongly boost its water intake because evaporative cooling is critical to relieving broodnest hyperthermia, and that it must rapidly boost its water intake because a colony maintains only a small water reserve. We also clarifi...

Electric vehicle battery electrodes are delaminated ultra-fast using high-powered ultrasound, separating active materials from the foil current collectors.

Intensified solvometallurgical process by combining solvoleaching and solvent extraction to recover cobalt from lithium oxide, in presence of current collectors aluminium copper.

This case study applies techniques of formal program development by specification refinement and composition to the problem of concurrent garbage collection. The specification formalism is mainly based on declarative programming paradigms, the imperative aspect is dealt with by using monads. We also sketch the use of temporal logic in connection with monadic specifications.

Garbage-producing and efficient programming languages such as Haskell, Lisp or ML have traditionally not been used for generating individual samples in realtime. The reason is a lack of garbage collector fast and predictably enough to make these languages viable alternatives to C and C++ for high performing audio DSP. This paper shows how conservative garbage collectors can be used efficiently ...

BACKGROUND The risk of transmission of tuberculosis is high in crowded conditions. Addis Ababa has a relatively high burden of tuberculosis and its city buses are often filled with commuters. Tuberculosis is a potential occupational hazard for city bus drivers and cash collectors. OBJECTIVES The objective of this study was to estimate the proportion of tuberculosis among city bus drivers and ...

We demonstrate a controlled growth of nitrogen-doped graphene layers by liquid precursor based chemical vapor deposition (CVD) technique. Nitrogen-doped graphene was grown directly on Cu current collectors and studied for its reversible Li-ion intercalation properties. Reversible discharge capacity of N-doped graphene is almost double compared to pristine graphene due to the large number of sur...
