We investigate the influence of fractal structure on material properties. We calculate the statistical correlation functions of fractal media defined by level-cut Gaussian random fields. This allows the modeling of both surface fractal and mass fractal materials. Variational bounds on the conductivity, diffusivity and elastic moduli of the materials are evaluated. We find that a fractally rough...

The subject of this research is linguistic (or: language) audit. The term is new and not being widely used so far. Linguistic audit, in particular, is offered as a service of linguistic-consulting agencies’ activities. Modern linguistic consulting, according to the author, is a form of stimulating theoretical and practical development of linguistic ecology, a new branch of applied linguistics, ...

The notion of fitness landscapes, a map between genotype and fitness, was proposed more than 80 years ago. For most of this time data was only available for a few alleles, and thus we had only a restricted view of the whole fitness landscape. Recently, advances in genetics and molecular biology allow a more detailed view of them. Here we review experimental and theoretical studies of fitness la...

iran with 2500 years ancient culture has been the witness of many changes during the history.the natural context of these habitats has been the victim of some changes during the years, which have roots in people beliefs in each period. but the point which we understand by studding the context of different cultures in iran is, despite the changes in dominions and religions along the history iran...

introduction this study is dealt with the environmental planning from a bio-cybernetic and hierarchical systems viewpoint within the context of landscape ecology. this viewpoint requires not only knowledge of the science of ecology but also ecological wisdom in order to recognize the place of humankind in nature. the conceptual and practical approach which is provided will help landscape planne...

Geographers have been reticent on the role of the African diaspora in the contouring of Brazil’s biological and cultural landscapes. Whereas paradigm shifts have occurred in regards to environmental stability in the tropical realm and the pristine nature of pre-Columbian landscapes, these have not translated to a rigorous reassessment of the geographical position of Africans and their descendan...

We specify a system of equations that fully reflects the supply and demand sides of the market for agricultural open space at equilibrium. Although simple, the system is exceedingly flexible and allows for household and parcel heterogeneity. We derive an empirical model directly from the structural equations and contrast this using a simulated landscape with the econometric specification most o...
