We consider the interpretation of emotions and simil-iar phenomena as support for survival and coping in the world. Grounded in the experience of an emotional agent, certain such emotions, drives or experiences are self-oriented (homeostasis, intake, outtow: hunger, pain, irritation), while others suggest a generalized or speciic recognition of other agents or objects (curiosity , fear; or hatr...

Curcuminoids refer to three main chemical substances, namely curcumin, demethoxycurcumin, and bis-demethoxycurcumin. These are used as natural coloring agents in some food products and have been reported to exhibit several biological activities in animal and human clinical studies. Due to its beneficial effects to human health, several analytical methods have been continuously proposed and deve...

The most traditional object of falsification, taking into account the volume consumption and cost, is wine. A significant proportion adulteration red wines accounts for imitation their color by introducing compounding ingredients to white base wine: synthetic coloring agents, natural food or products with a secondary effect. purpose this research was study physicochemical parameters original fa...

Plant sources, chemical properties, bioactivities, as well as the synthesis of indigo dye and its derivatives, are reviewed in this paper. These compounds were chosen because of their significant benefits and scope of application as both coloring agents in the textile industry and as pharmacologically active natural products. Their use in traditional chinese medicine (TCM) has directed the atte...

A total coloring of a graph G is a coloring of all elements of G, i.e. vertices and edges, such that no two adjacent or incident elements receive the same color. Let L(x) be a set of colors assigned to each element x of G. Then a list total coloring of G is a total coloring such that each element x receives a color contained in L(x). The list total coloring problem asks whether G has a list tot...

We introduce a new nature inspired algorithm to solve the Graph Coloring Problem (GCP): the Gravitational Swarm. The Swarm is composed of agents that act individually, but that can solve complex computational problems when viewed as a whole. We formulate the agent’s behavior to solve the GCP. Agents move as particles in the gravitatory field defined by some target objects corresponding to graph...
