Characterization of residual biomasses from the coffee production chain and assessment the potential for energy purposes
(Elsevier, 2018-11-19)
Chemical quantitative characterization of biomass is relevant for waste to energy recovery technologies. In the present work, selected agroindustry solid residues from coffee crops – parchment and coffee shrub, i.e., stem, ...
Steps towards more environmentally sustainable municipal solid waste management – A life cycle assessment study of São Paulo
(Elsevier, 2018)
Landfill disposal has thus far been the predominant treatment method for municipal solid waste (MSW) throughout Brazil, including São Paulo city. Environmentally sustainable development of MSW management in São Paulo ...
Environmental Impacts and Sustainability of Low-Value Roach Fish When Used as Food
(Elsevier, 2018-12-10)
One of the major global environmental challenges is the overuse of nutrients and related eutrophication problems. Specifically in Finland, the roach fish population is rapidly increasing in eutrophic water systems. Currently ...
Effect of heat integration method and torrefaction temperature on the performance of an integrated CHP-torrefaction plant
(Elsevier, 2015-07-01)
An important factor for industrial-scale implementation of torrefaction – a thermal pre-treatment technology that enhances the fuel characteristics of biomass – is the requirement for a low-cost source of heat energy. ...
Balancing of a Rotor with Active Magnetic Bearing System: Comparison of One-and Two-Plane Balancing Procedures
(IEEE, 2018-11-01)
Rotor balancing is a procedure used to reduce the unbalance vibration of rotating machinery. Unbalance vibration creates forces to the bearings and causes harmful effects such as reducing their lifespan. Unbalance is caused ...
Why Smart Appliances May Result in a Stupid Grid: Examining the Layers of the Sociotechnical Systems
(IEEE, 2018-10-17)
This article discusses the unexpected consequences of idealistic conceptions about the modernization of power grids. It focuses on demand?response policies based on automatic decisions made by smart home appliances. Following ...
Frequency analysis of chugging condensation in pressure suppression pool system with pattern recognition
(Elsevier, 2018-12-01)
Direct contact condensation (DCC) phenomena in boiling water reactor (BWR) pressure suppression pool systems need to be understood to properly assess the performance of the pool as a heat sink and as a safety critical ...
Pool stratification and mixing induced by steam injection through spargers: analysis of the PPOOLEX and PANDA experiments
(Elsevier, 2018-07-20)
Spargers are multi-hole injection pipes used in Boiling Water Reactors (BWR) and Advanced Pressurized (AP) reactors to condense steam in large water pools. A steam injection induces heat, momentum and mass sources that ...
Towards large, fossil free mills with integrated biorefineries : trends in modern pulp mills
(ABTCP, 2018-10-23)
Global economics require ever larger pulp mills with increased energy efficiency. Paris agreement means pulp and paper mills need to significantly reduce fossil fuel based carbon dioxide emissions. World markets are turning ...
Assessing the potential for renewable energy powered desalination for the global irrigation sector
(Elsevier, 2019-07-29)
By 2050, it is estimated that the annual cereal production would need to increase by about 140% and total global food production increase by 70%. Meanwhile, total water withdrawals for irrigation are projected to increase ...
