Non-methane hydrocarbons (NMHCs) are a group of low molecular weight compounds containing only hydrogen and carbon atoms in the C 2 -C 12 range, not only acts as a major precursor for the formation of O 3 through oxidation, but also cause several health problems. Cooking oil fume (COF) is one of...

Algae is a very promising source for renewable energy production since it can fix the greenhouse gas (CO2) by photosynthesis and does not compete with the production of food. Compared to microalgae, researches on biofuel production from macroalgae in both academia and industry are at infancy for...

Purpose: This paper aims to answer the following four research questions: Where do tourists gaze at the destination? What do tourists gaze at the destination? How do tourists gaze differently? Why do tourists gaze differently referring to relevant theory? Design/methodology/approach: With a...

Purpose: This study aims to conduct an empirical investigation of differing perceptions of nine types of urban space and nine visual elements among tourists in destination using a computer vision (CV) approach. Design/methodology/approach: The data for this study was extracted from YFCC 100 M...

Recently spectral perturbations, involving eigenvalue and eigenvector perturbations, which have attracted more attentions than conventional topological perturbations, are used to analyze and promote the robustness of complex networks. However, to the best of our knowledge, the study of...

In this work, an Al2O3-coated SiC foam monolith was used as the support of a Ni-based catalyst, which was applied for coupling partial oxidation and steaming reforming of methane to produce syngas or hydrogen. This monolithic catalyst showed excellent structural stability in a 900h endurance...
