today as the land-filling of solid wastes without taking into consideration the environmental issues would threaten the land greatly, the selection of an appropriate site for hygiene disposal of the wastes is a necessity. analytic hierarchy process (ahp) is one of the most frequently used methods of multiple criteria choices. in site selection of an optimum place fro landfill in the city of bon...

One of the most important causes of environmental pollution is certainly an inadequate waste management. The three factors that have primarily influenced this problem area are: ever increasing amount of municipal solid waste (which causes increasingly pronounced space occupation), increasing amount and types of hazardous waste, as well as lack of awareness on the importance of acting promptly i...

abstract in current world environmental and mainly urban wastes are originated mostly from massive human habitat areas, and have caused disturbance, uncomfortable landscape, environmental risks and dissatisfaction. saqqez city with a population of 140000 is one of the largest cities in kurdistan province. due to population increase, consumptions and changes in nutritional habits of people, the ...

In the forty-plus years since malls first appeared, these shopping centers have evolved into an integral part of the American culture. However, in recent years the number of malls has increased so dramatically that competition between malls, and even mall closures have become commonplace. Although there is not a large body of work that studies malls from a marketing perspective, the vast majori...

This article critiques existing store-location models and explains the many mathematical and methodological problems inherent in these models. The key issues are that behavioral factors are completely omitted in these models, emphasis on distance in un-warranted and site-specific and retailer-specific characteristics are typically omitted in these model. The author introduces new site-selection...

In this article we explore statistical properties of the maximum-likelihood estimates (MLEs) of the selection and mutation parameters in a Poisson random field population genetics model of directional selection at DNA sites. We derive the asymptotic variances and covariance of the MLEs and explore the power of the likelihood ratio tests (LRT) of neutrality for varying levels of mutation and sel...

Retroviral replication proceeds through an obligate integrated DNA provirus, making retroviral vectors attractive vehicles for human gene-therapy. Though most of the host cell genome is available for integration, the process of integration site selection is not random. Retroviruses differ in their choice of chromatin-associated features and also prefer particular nucleotide sequences at the poi...

Site-selection algorithms are used in reserve design to select networks of sites that maximize biodiversity, given some constraints. These algorithms are based on a snapshot of species occurrence, and they typically aim to minimize the area or cost needed to represent all the species once or a few times. Most of these algorithms ignore the question of how well species are likely to persist in t...
