The influence of the painting process on a biocompostable waste is studied. Disintegration degree (D %) of a 100% biocompostable plastic made from potato almidon is calculated for both painted and non -painted samples. Solid matrix is also characterized by means of a laboratory scaled composting process following UNE-EN norms [2, 3]. It can be concluded that painting has a negative influence on...

A proper edge t-coloring of a graph is a coloring of its edges with colors 1, 2, ..., t such that all colors are used, and no two adjacent edges receive the same color. For any integer n ≥ 3, all possible values of t are found, for which there exists such a proper edge t-coloring of the simple cycle C(n), which uses for each pair of adjacent edges either consecutive colors or the first and the ...

Proprietary de facto standards are seldom formalized. This paper examines a case, the JavaTM Technology of Sun Microsystems, where this was attempted. Sun approached the ISO/IEC JTC1 standards body and later the ECMA standards consortium to formalize Java. It withdrew both times. In this paper, I examine what motivated Sun's actions. A conceptual framework is applied that distinguishes two leve...

Wikipedia has claimed for over 3 years now that John von Neumann was the 'first quantum Bayesian'. In context, this reads as stating that von Neumann inaugurated QBism, the approach to quantum theory promoted by Fuchs, Mermin and Schack. This essay explores how such a claim is, historically speaking, unsupported.
