This paper describes the development and exploration of a tool designed to assist in investigating ‘cool’ as it applies to the design of interactive products for teenagers. The method involved the derivation of theoretical understandings of cool from literature that resulted in identification of seven core categories for cool, which were mapped to a hierarchy. The hierarchy includes having of c...

To better constrain models of cool core galaxy cluster formation, we have used X-ray observations taken from the Chandra and ROSAT archives to examine the properties of cool core and non-cool core clusters, especially beyond the cluster cores. Using an optimized reduction process, we produced X-ray images, surface brightness profiles, and hardness ratio maps of 30 nearby rich Abell clusters (17...

Background: Short time preservation of semen is common in animals (e.g. horse or pig etc…) which their sperm in known as freezing sensitive sperm. It also may use for short transportation of other species to be cryopreserved or use in AI or IVF programs. The aim of the present study was to evaluate effects of duration of cool storage on goat epididymal sperm. Materials and Methods: Total number...

Our planet has reached extreme weather conditions. Recently , a tornado in the US killed 519 people. Floods in Asia and Australia killed 2,000 and left large swaths of each country under water. Korea had its heaviest snowfall in recorded history. My heart goes out to all the families of the victims of the recent serious disasters. These events have been shaped by global warming. Scientists have...

This paper presents a simple method to measure people’s perceptions of the coolness of other people in localized social networks. Folk concepts of cool suggest that cool is real and yet elusive. Approaches to measuring cool that are indebted to traditional personality theory are shown to be insufficient because cool is a constantly changing construct. Instead, the tension between the real and e...

We present a new model for the creation of cool cores in rich galaxy clusters within a ΛCDM cosmological framework using the results from high spatial dynamic range, adaptive mesh hydro/N-body simulations. It is proposed that cores of cool gas first form in subclusters and these subclusters merge to create rich clusters with cool, central X-Ray excesses. The rich cool clusters do not possess “c...
