Gluten-Free Beer via Hydrodynamic Cavitation Assisted Brewing ofBarley Malts

We provide evidence that novel brewing technology based on controlled hydrodynamic cavitation greatly reduces gluten concentration in wort and finished beer. We advance the hypothesis that the degradation of proline, the most recalcitrant among gluten constituents, leads to gluten concentration reduction in the unfermented as well as in the fermenting wort and later during maturation. These fin...

Properly Coloured Hamiltonian Paths in Edge-coloured Complete Graphs

We consider edge-coloured complete graphs. A path or cycle Q is called properly coloured (PC) if any two adjacent edges of Q differ in colour. Our note is inspired by the following conjecture by B. Bollobás and P. Erdős (1976) : if G is an edge-coloured complete graph on n vertices in which the maximum monochromatic degree of every vertex is less than bn/2c, then G contains a PC Hamiltonian cyc...

Large 2-Coloured Matchings in 3-Coloured Complete Hypergraphs

We prove the generalized Ramsey-type result on large 2-coloured matchings in a 3-coloured complete 3-uniform hypergraph, supporting a conjecture by A. Gyárfás.

Multi-Coloured Hamilton Cycles In Random Edge-Coloured Graphs

We de ne a space of random edge-coloured graphs Gn;m; which correspond naturally to edge -colourings of Gn;m. We show that there exist constants K0; K1 21 such that provided m K0n logn and K1n then a random edge coloured graph contains a multi-coloured Hamilton cycle with probability tending to 1, as the number of vertices n tends to in nity.
