recent technological improvements have extended the application range of dielectric permittivity biomass measurements to on-line monitoring of physiological changes during bacterial fermentations. in an industrial fermentation of bacillus thuringiensis, it is important to verify the intactness of bacterial plasmid content in all steps of culture. changes in certain plasmid resident properties o...

Bio-inspired aggregation is one of the most fundamental behaviours that has been studied in swarm robotic for more than two decades. Biology revealed that the environmental characteristics are very important factors in aggregation of social insects and other animals. In this paper, we study the effects of different environmental factors such as size and texture of aggregation cues using real ro...

Innate social behaviours emerge from neuronal circuits that interpret sensory information on the basis of an individual’s own genotype, sex and experience. The regulated aggregation behaviour of the nematode Caenorhabditis elegans, a simple animal with only 302 neurons, is an attractive system to analyse these circuits. Wild social strains of C. elegans aggregate in the presence of specific sen...

background: planning the educational programs and informing people regarding the prevention of widespread diseases like cancers is necessary. with regard to high mortality rate of gastric cancer, the present study was conducted to define the effect of education based on health belief model on knowledge, attitude and nutritional practice of homemakers. materials and methods: in this intervention...

The different association behaviours of surfactants in water and other solvents have stimulated the interest to elucidate how the solvent properties influence aggregation, and many studies have been performed to gain information on the role of the solvent in the aggregation phenomenon of amphiphiles. These investigations have focused mainly on two essential aspects: namely the nature of the int...

Recent findings suggest that grouping with conspecifics is part of the behavioural defences developed by amphipod crustaceans to face predation risk by fish. Amphipods commonly serve as intermediate hosts for trophically transmitted parasites. These parasites are known for their ability to alter intermediate host phenotype in a way that promotes predation by definitive hosts, where they reprodu...

Unravelling the unique effects of metal coordination on biological behaviours is of importance to design metal based therapeutic and diagnostic agents. In this work, we chose luminescent Znsalen (ZnL1 ) as a case study to demonstrate that metal induced aggregation arising from the intermolecular Zn···O interaction influences its cellular uptake and subcellular localization. Comparative studies ...

Many bacteria exhibit multicellular behaviour, with individuals within a colony coordinating their actions for communal benefit. One example of complex multicellular phenotypes is myxobacterial fruiting body formation, where thousands of cells aggregate into large three-dimensional structures, within which sporulation occurs. Here we describe a novel theoretical model, which uses Monte Carlo dy...
