Development of Complex Mathematical Model of Light Naphtha Isomerization and Rectification Processes

The technique of developing a mathematical model of catalytic isomerization of light naphtha is stated Using experimental data from an industrial isomerization unit shows adequacy of the mathematical model to the real process. The paper presents a method for optimizing the operation of the plant together with catalytic isomerization unit and separation columns. Selection of optimal modes of separation columns allows achieving the desired flow separation between units, as well as extension of the life of the catalyst SI-2

Temporary techno-social gatherings? A (hacked) discussion about open practices

This paper is rooted in an experimental inquiry of issue-oriented temporary techno-social gatherings or TTGs, which are typically referred to as hackathons, workshops or pop-ups and employ rapid design and development practices to tackle technical challenges while engaging with social issues. Based on a collaboration between three digital practitioners (a producer, a researcher and a designer), qualitative and creative data was gathered across five different kinds of TTG events in London and in Tartu which were held in partnership with large institutions, including Art:Work at Tate Exchange within Tate Modern, the Mozilla Festival at Ravensbourne College and the 2017 Association of Internet Researchers conference hosted in Tartu. By analysing data using an open and discursive approach manifested in both text and visual formats, we reflect on the dynamic and generative characteristics of TTG gatherings while also arriving at our own conclusions as situated researchers and practitioners who are ourselves engaged in increasingly messy webs where new worlds of theory and practice are built

'New London Facets' mural painting

Photograph of a mural titled "New London Facets" by Lloyd R. Ney. The mural is located in the New London, Ohio post office. It is oil on canvas and measures 5' by 14'. The mural was created in 1940 with funding from the Section of Painting and Sculpture, a depression era public works program administered by the Treasury Department that provided work for unemployed artists. They awarded commissions through competitions and paid artists for their work, for a total of more than 1300 murals and 300 sculptures
