Pyrotechnic Universe

One of the central points of the ekpyrotic cosmological scenario based on Hor̆ava-Witten theory is that we live on a negative tension brane. However, the tension of the visible brane in HW theory, as well as in relevant cases of non-standard embedding, is positive. To make this scenario realistic one must solve the problem of the negative cosmological constant on the visible brane and fine-tune ...

Development of Filters for a Thermoelectric Colorimeter

Filters have been designed for use with phoLocells and pho totubes in t ris Limulus colorimeters, but because of the variation in spectral response of t hese detecLors from one Lo t he other, it has not been worthwhile to attempt to achieve the best possible dup li cation or the CIE t ristim ulus func t ions. In t he case of a thermoelectric detector, however, th e response is so nonselective t...

Talking About The Smokes

Design, setting and participants: The Talking About The Smokes project used a quota sampling design to recruit 1392 daily smokers from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait from April 2012 to October 2013. These were compared with 1010 daily smokers from the general Australian population surveyed by the International Toba...
