ABSTRACT:
An experimental study examined the effects of participant motivation (required vs. voluntary participation) and experimenter demeanor (participants treated as co-researchers or as data-producers) on compliance and participant attitude. Participants completed a meaningless task and then filled out a questionnaire about their attitudes toward the experimenter and task. Compliance was measured by how long and how accurately participants worked on the task. Results indicate that Participant Motivation type affects attitudes toward the experimenter and task and Experimenter Demeanor affects compliance on a task. Voluntary Co-Researcher participants had more positive attitudes and marked on the most number of pages but did not complete the task correctly compared to other participants. Future research could increase the impossibility of the task to see how much participants will comply, and should look at the effect on compliance that a greater difference in position between experimenters and participants may have.

ABSTRACT:
As the demand for faster and cheaper integrated circuits prevalent in today’s technology continues to rise, there is a challenge to produce even smaller and faster circuits in less time and for less cost. Our work explores the superior conductivity of silver metal for the application as a more conductive metal interconnects in next generation integrated circuits. In this work, ruthenium was chosen as the diffusion barrier platform on which a precise and uniform coating of silver would be deposited electrochemically. However, the adhesion testing revealed poor adhesion between deposited Ag thin film and its Ru substrate. The adhesion problem was corrected by installing a thin Cu priming layer on Ru prior to Ag deposition. A two- steps Ag plating protocol was developed to overcome the unwanted Ag displacement reaction with Cu and achieved the preparation of Ag/Cu/Ru multiplayer, which showed good adhesion after peel test.

ABSTRACT:
Condition monitoring of power substations is a significant issue for the National Electric Power Authority (NEPA) of Nigeria. Current methods for monitoring the condition of high voltage equipment are time consuming and often inaccurate, therefore causing catastrophic damage to the substation equipment. Recent research has demonstrated the efficacy of employing optical fiber sensors in condition monitoring of substation equipment. These sensors enhance the current monitoring method and facilitate faster responses to equipment problems. This paper briefly reviews the state of the arts, but is primarily devoted to a discussion of the new approach and future directions in condition monitoring of NEPA substation equipment.

ABSTRACT:
This article discusses the effectiveness of Prussian Blue (PB) or KxFeAx[Fe BY(CN)6]z thin films as a model to demonstrate the concept of reversibility of electron and ion exchange processes. PB structure is modified via exchanging the FeA (the counter ion) with other metal ions that have electrochemically active or inactive redox behavior. The modeling process includes the investigation of the electrochemical behavior of PB before and after modification. The results can be compared and used to derive conclusions about the validity of PB as a model compound.
