Given a mapping $f:Xto X$ we naturally associate to it a monotonic map $gg_f:exp Xto exp X$ from the power set of $X$ into itself, thus inducing a generalized topology on $X$. In this paper we investigate some properties of generalized topologies which are defined by such a procedure.

However these projects continue to have high failure rates thus highlighting the need for improved risk management. A stream of IS research has focused on identifying several causes of managerial risks. The theory base that has been used in t...

Increased demand for better technology and perpetual global expansion continue to provide developers with many project opportunities for success, as well as failure. While no industry is immune from project failure, the Information Technology (IT) industry is shown to be more susceptible to risk and failure than those of other industries. Agile project management, which facilitates adaptation t...

Pulmonary bullae occur as insulated abnormalities in approximate normal lung tissue or in the presence of emphysema. The steady expansion of lung bulla is common; however, its mechanism is still unclear, but can impulse life threatening conditions that requires emergent surgical intervention. Spontaneous complete or partial resolution also known as “autobullectomy” of giant pulmonary bullae is ...
