Abstract Waste plastic gasification for hydrogen production combined with carbon capture and storage is one technology option to address the waste challenge. Here, we conducted a techno-economic analysis life cycle assessment assess this option. The minimum selling price of 2000 oven-dry metric ton/day mixed plant US$2.26–2.94 kg −1 hydrogen, which can compete fossil fuel (US$1.21–2.62 hydrogen...

As the offshore energy landscape transitions to renewable useful decommissioned or abandoned oil and gas infrastructure can be repurposed in context of circular economy. Oil platforms, for example, offer opportunity hydrogen (H2) production by desalination electrolysis sea water using wind power. However, as H2 storage transport may prove challenging this study proposes react with carbon dioxid...

Reducing CO2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. While a variety of technologies and methods have been developed, the separation of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of membrane materials with high separation performance ...

this study presents empirical evidence concerning the effect of different accounting standard on earnings management. prior studies have shown that accounting standards influence earnings management. tighter accounting standards regime restricts management’s descretion to manipulate accruals, and at the same time, induce more costly real earnings management activities. to investigate this iss...

The movement parameters of yellow fin tuna schools were analyzed by means of scanning sonar in tuna purse seine capture situations in the Oman Sea in June 2010. There was significant difference in swimming speed and radial swimming direction between the escaped and captured schools. In escaped cases, the fish schools swam faster with mostly horizontal avoidance behavior to the sound stimuli fro...

While over-dispersion in capture–recapture studies is well known to lead to poor estimation of population size, current diagnostic tools to detect the presence of heterogeneity have not been specifically developed for capture–recapture studies. To address this, a simple and efficient method of testing for over-dispersion in zero-truncated count data is developed and evaluated. The proposed meth...

The main function of the photosynthetic process is to capture solar energy and to store it in the form of chemical 'fuels'. Increasingly, the photosynthetic machinery is being used for the production of biofuels such as bio-ethanol, biodiesel and bio-H2. Fuel production efficiency is directly dependent on the solar photon capture and conversion efficiency of the system. Green algae (e.g. Chlamy...
