Column leaching heavy metal from tailings following simulated climate change in the Arctic area of Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
This study aimed to assess how the current climate change perspective, with various air temperature (4°C, 10°C, 14°C and 18°C) affected metal releasing from tailings. Heavy metals pollution from tailings leaching are of increasing concern. Column leaching experiment was conducted for 15 weeks to a series of tailings with 20 mm/week water leaching four temperature situations. Leachate chemical physics ...
Endurance Test on Carbon Film Fixed Resistor under Escalated Voltage Stress
(Journal article; Peer reviewed; Tidsskriftartikkel, 2018)
Film fixed resistor is a basic unit in the electronic devices. As it is less frequently failed than other units such as capacitor, the reliability and robustness of it are less concerned both in the academics and in the industries. This paper investigates the endurance of the carbon film fixed resistor. The resistance shift and life of it under the escalated voltage stress level are the aim. A PCB ...
