The Boundary Element Method has been applied to calculate stress distribution and stability of underground mines for disposal of chemical waste. A case similar to the Stripa mine in Sweden has been considered. The rock mass was granite, with major fracture zones represented by three families of planes mutually orthogonal and 100 meters distant from each other. The pre and post processor GiD [3]...

Model completeness results for expansions of the ordered eld of real numbers by restricted Pfaaan functions and the exponential function. for discussions and comments, anonymous referees for suggesting numerous improvements, and Mihalis Yannakakis for his suggestions that helped improve the presentation.

sustained is by omitting any reference to the sensation novels thronged with palpably nervous middle-class bodies which gave rise during the 1860s to a fury of indignation. "The reader's nerves are affected like the hero's", Margaret Oliphant stridently complained in a review of the most famous of them all, Wilkie Collins's The woman in white (1860). Such omissions make Nerves and narratives, a...

A new type of cosmic-ray experiment is under construction in the Pyhäsalmi mine in the underground laboratory of the University of Oulu, Finland. It aims to study the composition of cosmic rays at and above the knee region. The experiment, called EMMA, will cover approximately 150 m of detector area. The array is capable of measuring the multiplicity and the lateral distribution of underground ...

abandoned surface mine excavations can be a major environmental, social and/or human healthproblem for the mining industry as well as for the community living nearby. this problem is exacerbated by therapidly growing population encroaching on areas of historic mined lands. the aim of this studywas to assess thesafety status of the historic nyala mine excavation with the purpose of coming up wit...

This paper incorporates labor search frictions into a model with lumpy investment to explain a set of …rm-size-related facts about the United States labor market dynamics over business cycles. Contrary to the predictions of standard models, we observe that job destruction is procyclical in small …rms but countercyclical in large ones. Calibrated to U.S. data, the model generates this asymmetric...

The activities of mining exploitation in Campo de Jales were performed in an uncontrolled way and gave rise to serious environmental contamination: rubbish depositories have been accumulated with no treatment or maintenance. An investigation developed around Jales Mine showed the existence of some chemical impact originated from the waste produced during mining activities. Some "black spots" fo...
