• Mixture of glass powder and water is atmosphere sensitive. Reaction with CO 2 results in the formation carbonates. Newly formed carbonates are main source expansion gas (CO ). New mechanism foaming proposed. Water a common additive process direct glass, however, currently accepted lacks experimental validation. A mixture waste cathode ray tube panel was investigated for its evolution behavior...

Calcium isotopes of carbonate rocks can trace calcium cycles and record changes in the marine environment. As published isotope profiles at Permian-Triassic boundary are rare, comparative studies on deep-water were lacking for major extinction event that occurred during this time. We present sections different water depths Chibi area southern China we have selected a study. analyzed carbon isot...

We investigated calcite globules and veins in two spinel-garnet peridotite xenoliths from the subSierra Nevada mantle. The studied xenoliths were entrained in a Miocene (11 Ma) volcanic plug. These carbonates are associated spatially with silicate glass inclusions, suggesting that they are primary inclusions—inclusions that formed at high temperature in the mantle and not at or close to the Ear...

Over recent years, the study of games and players has become an established domain with HCI research. However, while a range of methods has been employed within this area, questions remain as to how to develop in-depth understandings of players and the contexts they play within. Drawing upon the social sciences, this paper proposes case studies as an additional methodology for player research. ...

In this introductory chapter, we describe the key lessons from an earlier HCI Educators’ conference, held in Limerick in 2006, the outcomes of which led to the theme of HCIEd 2007 – Creativity: Experiencing to Educate and Design. The paper discusses the lessons leant around four key questions: nature vs. nurture: can creative invention be taught; what tools and methods are there to help student...

Gamification has been widely accepted in the HCI community in the last few years. However, the current debate is focused on its short-term consequences, such as effectiveness and usefulness, while its side-effects, long-term criticalities and systemic impacts are rarely raised. This workshop explores the gamification design space from a critical perspective, by using design fictions to help res...

Papers in HCI play different roles, whether to inspire, solve industrial problems or further the science of HCI. There is a potential conflict between the different views, and a danger that different forms of validity are assumed by author and reader — deliberately or accidentally. This paper reviews some of the issues in this complex area and makes
