How to publish in this journal

Scope

PSEP aims to be the principal international journal for publication of high quality, original papers in the branches of engineering concerned with the safety of industrial processes and the protection of the environment. Papers that deal with new developments in safety or environmental aspects, demonstrating how research results can be used in process engineering design and practice, are particularly encouraged. Experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research will also be considered. The journal is especially interested in contributions that extend the boundaries of traditional engineering as well as in multidisciplinary papers. Papers related to environmental protection must take an integrated pollution control approach, demonstrating clearly that any proposed treatment method does not simply transfer pollution from one environmental medium to another, for example, from air to water or from water to solid waste. All such papers must discuss how any treatment effluents, spent adsorbents, etc., can be treated or disposed of safely, avoiding transfer of pollution to another environmental medium.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
