Dark fermentative hydrogen production from lignocellulosic hydrolyzates – A review

Abstract: The demand for renewable energy is increasing due to increasing energy consumption and global warming associated with increasing use of fossil fuels. Hydrogen gas is considered as a good energy carrier due to its high energy content. Biomass (e.g. agricultural and forestry residues, food industry wastes, and energy crops) is amenable to dark fermentative hydrogen production. However, lignocellulosic materials require pretreatment and/or hydrolysis prior to dark fermentation. This paper reviews potential biomass sources for hydrogen fermentation as well as the effects of different pretreatment and hydrolysis methods on sugar yields as well as hydrogen yields from hydrolyzates. The effects of process parameters on dark fermentative hydrogen production from lignocellulosic hydrolyzates are also discussed.

A Diary Study on Combining Multiple Information Devices in Everyday Activities and Tasks

Abstract: As people possess increasing numbers of information devices, situations where several devices are combined and used together have become more common. We present a user study on people's current practices in combining multiple information devices in their everyday lives, ranging from pragmatic tasks to leisure activities. Based on diaries and interviews of 14 participants, we characterize the usage practices of the most common devices, including smartphones, computers, tablets, and home media centers. We analyze 123 real-life multi-device use cases and identify the main usage patterns, including Sequential Use, Resource Lending, Related Parallel Use, and Unrelated Parallel Use. We discuss the practical challenges of using several information devices together. Finally, we identify three levels of decisions that determine which devices are used in a particular situation, including acquiring, making available, and selecting the devices for use.
