21. Filtration of Cellulosic material - the impact of ionic strength and electric field
Abstract : It is crucial that dewatering technology is considered if an economically feasible production of cellulosic materials is to be achieved. Cellulosic materials are often produced in dilute streams and therefore require great amounts of water to be removed to allow for reasonable transportation costs and/or further modifications.

25. The impact of railway vibration and noise on sleep
Abstract : Sleep is a vital component of good health, and sleep loss is associated with impaired cognition, decreased psychomotor performance, cardiovascular disease, adverse effects on endocrine and metabolic function, negative mood, impaired memory, and more. A growing burden of freight transportation on global railway networks will likely lead to an increase in nocturnal vibration and noise at nearby dwellings. READ MORE
