OVERVIEW Environmental chemistry is a very broad topic (Jardim, 1998; Ventura et al., 2009; Kubicki and Mueller, 2010; Steinbach and Hoffmann, 2010; Subramaniam, 2010; Caumul, 2011; Gao et al., 2011; Humphris, 2011; Wirth et al., 2011). This subject spans aspects of all states of matter and various phenomena including pollution, (Ashmore and Nathanail, 2008; Busca, 2009; Carls and Meador, 2009;...

We demonstrate that a simple solar dynamo model, in the form of a Parker migratory dynamo with random fluctuations of the dynamo governing parameters and algebraic saturation of dynamo action, can at least qualitatively reproduce all the basic features of solar Grand Minima as they are known from direct and indirect data. In particular, the model successfully reproduces such features as an abru...

We give some interpretations to certain integer sequences in terms of parameters on Grand-Dyck paths and coloured noncrossing partitions, and we find some new bijections relating Grand-Dyck paths and signed pattern avoiding permutations. Next we transfer a natural distributive lattice structure on Grand-Dyck paths to coloured noncrossing partitions and signed pattern avoiding permutations, thus...

John Gardner’s Grendel is a celebrated example of the ontological postmodernist fiction. Along with a discovery of self with which Grendel the narrator of the novel is concerned, grand narratives such as philosophy are questioned. Grendel denies the external objective reality and generously allows the legitimacy of fantastic and non-realistic methods by using “life-affirming fabulous art” as it...
