Retraction notice to “Critical radius for radial heat conduction: A necessary criterion but not always sufficient” [Appl. Therm. Eng. 24(7) (2003) 967–979] (S1359431103003508) (10.1016/j.applthermaleng.2003.08.017))

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the Editor-in-Chief. The author has re-used an unacceptable amount of text and figures from an earlier paper that had already appeared in the Journal of Thermal Envelope and Building Science (now Journal of Building Physics): M.R. Kulkarni, Introduction of a New Crossover Radius for Radial Heat Conduction, Part I: Cylindrical Systems, Journal of Thermal Envelope and Building Science, Vol. 22, pp. 72–88, 1998. http://journals.sagepub.com/doi/abs/10.1177/109719639802200106. One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to the authors of the original paper and readers of the journal that this was not detected during the submission or review process. The author would like to apologise to all parties affected.
