Optimize the measurement of Poly-hydroxy-alkanoates (PHA) in biomass

Poly-hydroxy-alkanoate (PHA) is an intracellular polymer that can be used as an energy and carbon source by microorganisms. Measuring PHA is important for understanding the microbial metabolism of enhanced biological phosphorus removal (EBPR) and aerobic granular sludge (AGS) systems. There is a commonly used method to measure PHA, which is...

Possibilities for treating produced water with ceramic membranes

Constant flux MF/UF filtration is preferred in real-world applications because it <br/>provides more consistent permeate flow rates than fixed transmembrane pressure studies. Particularly, little is understood about the fouling of ceramic membranes in constant flux filtration modes by nano-sized O/W emulsions. In this study, the effects of...

Electric Vehicle Pickup-and-Delivery Problem with Soft Time Windows, Partial Charging, and Uncertain Travel Time

Electric vehicles (EVs) take advantage of reducing fossil-based environmental pollution and developing a more sustainable logistics network. Compared with internal combustion engine vehicles (ICEVs), EVs have new technical characteristics like limited battery capacity and long charging time at charging stations. With the diffusion of EVs,...

Research on Ride-hailing Pricing Strategies

Compared to traditional public transport, ride-hailing makes it possible for people to get a more comfortable and faster riding experience with a higher fare. Ride-sharing fall in between the two, offering a discount at the price level of ride-hailing, yet operates with more detours and less comfortable experience. In this study, with different...

Effects of Novel Rejuvenators on Chemical and Rheological Properties of Aged SBS Modified Bitumen

SBS modified bitumen is popularly utilized in road construction owing to its outstanding performance and competitive pricing. However, like normal bitumen, SBS modified bitumen will also be aged and causing asphalt pavement distress and the need for maintenance, resulting in a significant amount of wasted modified asphalt. Recycling waste...

Wavepool in a Natural Lake Environment: A Design Study for the Edges of an Artificial Surf Reef in the Noorderplas, Roermond

Wave surfing is a water sport in which a surfer uses a board to ride a wave towards the shore. It is done in the coastal areas around the globe. Each surf spot has its own wave quality depending on the wave climate and the type of coast. Some spots have year-round perfect waves and other surf spots only work ’when the stars are aligned.’ The...

Optimising the yard layout of Container Terminals: The port of Thessaloniki case

Over the last decades, containerisation became the major way to transport discrete goods replacing a part of general cargo trade and facing the increasing consumer demand of developed and developing world. As a result, container terminals became an important part of a lot of ports worldwide while new technology was developed to encounter the...

Assessment of Using Low-frequency Ultrasound Device for Domestic Drinking Water Disinfection

Microorganisms may cause problems in drinking water distribution system (DWDS). It is hard to control and always forms the biofilm, which can result in the deterioration of drinking water quality. At household’s tap, due to the favorable conditions, which incurs an easier formation of biofilm. Therefore, the idea of secondary disinfection at...

Redesign Frequency for Fixed-time and Vehicle-actuated Signal Controllers at A Right-turning Channelized Intersection

Fixed-time control and vehicle-actuated control are two main signaling strategies implemented at intersections for urban traffic management. The timing and structure of the controllers are usually designed optimally based on average historical demand patterns at the intersection. Under the premise of performance quality assurance, both fixed...

Improving Organic Micropollutant Removal of Activated Carbon by Pre-treatment with Zeolite Adsorbent

Activated carbon (AC) is commonly used in drinking water treatment plants (DWTPs) to remove organic micro-pollutants (OMPs), and it is effective in adsorbing a wide range of OMPs. However, its adsorption efficiency can be affected by natural organic matter (NOM). NOM is a complex matrix and widely exists in water bodies. During the drinking...

Ultrasound Disinfection in Domestic Drinking Water System

The quality of treated drinking water in the distribution network might deteriorate even though the quality of water leaving the treatment plant has been set to be at the highest level. Regrowth of microorganisms or known as microbiological instability is found to be one of the responsible causes for the change of the water quality. This...

MODIS snow cover data for calibration and evaluation of hydrological models in contrasting environments

This research studies different hydrological models in the catchments with various climates in the USA, and MODIS snow cover maps are introduced to assess and improve the models. In this research, assessment of the value of MODIS snow cover data in the hydrological modeling process is the main objective. Nine MOPEX catchments in the continental...
