we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...

Abstract Purpose - The aim of this paper is to describe the population ecology theory through fractal thinking, an emergent human operating system that is creative, adaptive, healthy, and evolutionary; furthermore, a parallel is drawn between the population ecology model and the fractal structure. Top-down hierarchies are typically characterized by command and control systems of the authority t...

This contribution is based on the assumption that solutions to most environmental problems will require the application of knowledge based on an understanding of how ecosystems and landscapes function and how they are linked in time and space. I also assume that almost all plans to solve environmental problems will be made with the knowledge that they are based on a limited and imperfect scient...

In this paper I describe some of the ways in which landscape ecology principles have been incorporated into land use planning and change. In Scotland we have tried developing landscape-scale or regional plans for land use change to resolve issues of habitat fragmentation – the ‘big plans’ of the title. We have also developed ‘little plans’ – much smaller proposals based on individual designated...

the present study attempts to discover ideological differences between alcott’s novel (1868) named “little women” and its two persian translations. the first has been translated by morvarid and the second has been translated by obeidi. to this end, farahzad’s cda approach (2012) was used to analyze the ideology reflected in both translations by the two different translators. according to farahz...

Evaluating ecological patterns and processes is crucial for the conservation of ecosystems [1]. In this view, remote sensing is a powerful tool for monitoring their status and change. This involves several tasks like biodiversity estimate, landscape ecology, and species distribution modeling, to name a few [2]. Due to the difficulties associated with field-based data collection [3], the use of ...

UK forests and woodlands are often of considerable value to biodiversity. There is now a growing need to evaluate the impacts of forest management on biodiversity, in order to maintain and enhance the wildlife value at the landscape scale. The development of biodiversity evaluation tools will enable forest and land managers to make informed choices at this scale in order to provide sustainable ...

We analytically put the concept of public administration into perspective in this paper. In the process, we traced its genealogy and, its theoretical provisions as well as the implications and challenges of these provisonal at each stage of its development. We specifically zeroed-in on the practical applications of these provisons in a country like Nigeria. Prominence was given to the features ...
