Abstract
3‐Aminopropanamide (3‐APA) is the direct precursor of acrylamide produced in the Maillard reaction between asparagine and reducing sugars. In this research, we found that 3‐APA could reduce acrylamide by the formation of adducts between acrylamide and 3‐APA via Michael addition. The effects of temperature, heating duration and 3‐APA/acrylamide ratio on the reduction of acrylamide were investigated...
Considerable progress has been made in recent years in the study of the Earth's gravitational field by observing the motion of satellites in low altitude orbits. However, such observations are hampered by the aerodynamic drag caused by the residual atmosphere, which modifies the orbits of these satellites in an unpredictable way. In order to overcome this problem, an on-board propulsion system with...
The cusped field thruster represents a new type of electric propulsion device incorporating cusped magnetic field profiles that keep high energy ions away from channel walls and mitigate erosion. Thus its lifetime will be longer compared with so me other type of electric propulsion devices. Recently, the cusped field thruster has been paid much attentions by many organizations, such as Thales Research...
A cusped field thruster with adjustable magnetic field strength is designed by Harbin Institute of Technology (HIT). The thruster produce thrust by accelerating the xenon ions in the electric field. Two different modes are found during the experiments, one is high anode current and low voltage mode, the other is low anode current and high voltage mode. Phenomena of intermittent large amplitude anode...
Fostering a positive safety culture is fundamental and critical for improving safety performance on a construction site. However, the complexity and evolutionary process of safety culture in a construction project team, which is different with other organizations, have not been well addressed and the basic model for construction project safety culture is still missing. The objectives of this paper...
This paper presents a mixed reality system for combining real robots, humans, and virtual robots. The system tracks and controls physical robots in local physical space, and inserts them into a virtual environment (VE). The system allows a human to locomote in a VE larger than the physically tracked space of the laboratory through a form of redirected walking. An evaluation assessed the conditions...
