A letter to the editor. Meals on Wheels (MOW) is a community-based not-forprofit organisation that delivers nutritious meals to vulnerable clients in the community, to enable them to maintain their health and independence within their own home. MOW meals aim to provide at least one-third of the recommended dietary intake (RDI) for energy, fibre and calcium, and one-half of the RDI for protein, ...

An original multiscale friction analysis is developed to characterize the interfacial phenomena during hot forging contact conditions in manufacture of wheels for railway industry. Hot upsetting sliding tests and roll-on-disc are performed reproduce tribological at meso micro-scale. Crushed embedded oxides found be present on sample's surfaces. Stick-slip occur due accumulation crushed oxides. ...

Let ex(n,C4) denote the maximum size of a C4-free graph of order n. For an even integer or odd prime power q > 6, we prove that ex(q2 + q + 2, C4) < 1 2(q+1)(q 2+q+2), which leads to an improvement of the upper bounds on Ramsey numbers R(C4,Wq2+2), where Wn is a wheel of order n. By using a simple polarity graph Gq for a prime power q, we construct the graphs whose complements do not contain K1...

An edge e of a simple 3-connected graph G is essential if neither the deletion G\e nor the contraction G/e is both simple and 3–connected. Tutte’s Wheels Theorem proves that the only simple 3–connected graphs with no non-essential edges are the wheels. In earlier work, as a corollary of a matroid result, the authors determined all simple 3-connected graphs with at most two non-essential edges. ...
