Food labelling on food packaging has the potential to have both positive and negative effects on diets. Monitoring different aspects of food labelling would help to identify priority policy options to help people make healthier food choices. A taxonomy of the elements of health-related food labelling is proposed. A systematic review of studies that assessed the nature and extent of health-relat...
The L(p, q)-Edge-Labelling problem is the edge variant of well-known q)-Labelling problem. It equivalent to itself if we restrict input latter line graphs. So far, complexity was only partially classified in literature. We complete this study for all $$p,q\ge 0$$ by showing that whenever $$(p,q)\ne (0,0)$$ , NP-complete. do proving except $$p=q=0$$ there an integer k so L (p q)-Edge-k -Labelling
Bandwidth labelling is a well known research area in graph theory. We provide a new proof that the bandwidth of Mobius ladder is 4, if it is not a $K_{4}$, and investigate the bandwidth of a wider class of Mobius graphs of even strips.
The biosynthesis of pyrrocidines, fungal PK-NRP compounds featuring a strained [9]paracyclophane, was investigated in Acremonium zeae. We used a synthetic L-tyrosine probe, labelled with oxygen 18 as a reporter of phenol reactivity and carbon 13 as a tracer of incorporation of this exogenous precursor. The ((18)O)phenolic oxygen was incorporated, suggesting that phenol behaves as a nucleophile ...
BACKGROUND AND PURPOSE The P2X(7) receptor exhibits complex pharmacological properties. In this study, binding of a [(3)H]-labelled P2X(7) receptor antagonist to human P2X(7) receptors has been examined to further understand ligand interactions with this receptor. EXPERIMENTAL APPROACH The P2X(7) receptor antagonist, N-[2-({2-[(2-hydroxyethyl)amino]ethyl}amino)-5-quinolinyl]-2-tricyclo[3.3.1....
A gracious labelling g of a tree is a graceful labelling in which, treating the tree as a bipartite graph, the label of any edge (d,u) (d a ‘down’ and u an ‘up’ vertex) is g(u) – g(d). A gracious k-labelling is one such that each residue class modulo k has the ‘correct’ numbers of vertex and edge labels that is, the numbers that arise by interpreting the labels of a gracious labelling modulo k....
We model the edit distance as a function in a labelling space. A labelling space is an Euclidean space where coordinates are the edit costs. Through this model, we define a class of cost. A class of cost is a region in the labelling space that all the edit costs have the same optimal labelling. Moreover, we characterise the distance value through the labelling space. This new point of view of t...
