The substantial increase in oil prices over the past few years has been reflected in asphalt prices. Moreover, the maximization of fuel production in refineries has reduced asphalt supply. These conditions have prompted the development of alternative sources of asphalt binders, including bio-oils derived from the fractionated fast pyrolysis of biomass that comes from agricultural and forestry r...

Cement-based materials have often been used for infrastructure construction and repair. The production of conventional Portland cement is energy-consuming and environmentally unfriendly. For example, production of one ton of Portland cement generates approximately one ton of carbon dioxide (CO 2 ) from calcining limestone and fuel use. It is estimated that cement production contributes 7% of to...

Abstract Assume that a researcher uncovers major problem with how social media are currently used. What sort of challenges arise when they must subsequently decide whether or not to use create awareness about this problem? This situation routinely occurs as ethicists navigate choices regarding effect change and potentially remedy the problems uncover. In article, related new technologies what i...

Mobile phones are becoming important instruments for assessing diet and energy intake. We developed the Tool for Energy Balance in Children (TECH), which uses a mobile phone to assess energy and food intake in pre-school children. The aims of this study were: (a) to compare energy intake (EI) using TECH with total energy expenditure (TEE) measured via doubly labelled water (DLW); and (b) to com...

While the traditional agency model assumes managerial risk aversion and underinvestment in high tech opportunities, the behavioural agency model allows for risk seeking by managers leading possibly to over-risky investment. Corporate governance mechanisms can correct both underand overrisky investment thereby ensuring value enhancing high tech acquisitions. Our study builds an empirical optimal...

In recent years, China’s high-tech industry has made remarkable technological progress, but it also brought serious environmental pollution, which aroused great concern about its efficiency. Although foreign technology transfer is considered as important ways for progress of the industry, existing research on what role plays in improving efficiency still lacking. Based interprovincial panel dat...
