Let $G$ be a simple connected graph. In this paper, Szeged dimension and PI$_v$ dimension of graph $G$ are introduced. It is proved that if $G$ is a graph of Szeged dimension $1$ then line graph of $G$ is 2-connected. The dimensions of five composite graphs: sum, corona, composition, disjunction and symmetric difference with strongly regular components is computed. Also explicit formulas of Sze...

In our work we saw that during the last decades the environment that the MNCs operate in has changed becoming more volatile and less pacedly growing. In this environment the MNCs themselves have become more complex and also flexible. We found that MNCs are essentially three dimensional, that is, they organize around product, functional and geographical dimensions and exhibit characteristics tha...

Identifying solutions and responses to global environmental change is one of the key challenges of the 21 st century. Research on ecosystem and species responses to climate changes and human impacts is vital to identify science-based solutions to ecological problems. Large-scale biodiversity data plays a key role in understanding the relationships among species distributions and the environment...
