Introduction Cruise port operations are facing increasingly significant challenges in departure reliability amid frequent climate variability, port congestion, supply chain disruptions, and geopolitical risks. Unlike existing studies that mainly explain cruise delays from the perspectives of weather conditions, external shocks, or supply chain risks, this paper focuses on whether port turnaround planning itself may constitute...

Waste heat recovery using Organic Rankine Cycle (ORC) systems shows significant potential for reducing CO2 emissions from ships. This study designs and analyzes ORC systems for recovering multi-grade waste heat from the exhaust gas, jacket water, and scavenging air of a marine two-stroke diesel engine. A thermodynamic model is developed to investigate the effects of working fluid preheating temperature, evaporation pressure, a...

Nitrous oxide (N 2 O) is a long‐lived greenhouse gas that can result in the alteration of atmospheric chemistry and cause accompanying changes in global climate. To date, many techniques have been used to mitigate the emissions of N 2 O from agricultural fields, which represent one of the most important sources of N 2 O. In this study, we designed a greenhouse pot experiment and a microcosmic serum bottle incubation experiment...
