Mechanism of SPS acceleration in a PEG containing copper plating bath
… effect of bis-(3-sodiumsulfopropyl) disulfide (SPS) which is believed to go through an electrochemical reaction to form sodium 3-mercapto-1-propanesulfonate (MPS), the effective accelerant. The accelerant is believed to operate by forcing the suppressor off the copper surface through competitive …

Biodegradable stents made of pure Mg and AZ91 alloy through SPS sintering
The implantation of stents is an effective procedure to unblock the arteries of patients with serious heart problems. Traditionally, stents are made of inert materials such as stainless steel and titanium alloys. It has been shown that the traditional stents can cause restenosis or thrombosis. In …

Statistical hadronization phenomenology in heavy ion collisions at SPS and RHIC energies
This dissertation examines the phenomenology of statistical hadronization at ultrarelativistic energies. We start with an overview of current experimental and theoretical issues in Relativistic heavy ion physics. We then introduce statistical hadronization, and show how it gives a description of …

A rotating ring-disk study of interactions among SPS, cuprous ions, and oxygen
… a suppressor, and bis-(3-sulfopropyl)-disulfide (SPS), an accelerant. The copper in acid plating baths is provided by a Cu (II) salt. Cu (I) may be present as well and it influenced the effectiveness of SPS. In this investigation, the interactions among SPS, Cu (I) and oxygen were studied by …

Facilitating software reuse by structuring the SPS user interface management system's software library according to programmer mental models
This study evaluates three different ways of structuring a software library for an object-oriented system. The traditional class/subclass tree (CIS) is used as well as two methods from the mental model literature: hierarchical cluster analysis (HCA) of sorting data and modal block clustering (MBC) …

The language game of role-play: an analysis of assessed consultations between third year medical students and Simulated Patients (SPs)
Simulated patients (SPs), are widely used in communication skills teaching and testing worldwide. However, little research has been undertaken regarding the linguistic structure of the simulated consultation between students and SPs. Mixed method analysis (Conversation Analysis, Discourse Analysis …
