In recent, the placement of backfill in underground mines has emerged as a new paradigm in research as it not only improves safety but also allows disposal of byproducts including coal ash. In this regards, this paper addresses the backfilling challenges in limestone mine to prevent sinkhole and subsidence. Limestone mines, generally regarded as being safer than coal and metal mines, have been ...

ABStrAct Background: An estimated 1.7 bil­ lion people worldwide are affected by obesity­related comorbidities such as cardiovascular disease and diabetes. Bariatric surgery is recog­ nized as an effective treatment for morbid obesity. A study of patients at a Bc clinic was undertaken to deter­ mine if combining bariatric surgery with comprehensive care provided by a multidisciplinary team impr...

The explicit management of project experience (lessons learned on project planning and execution) has become of strategic importance to many organizations. This paper describes how to set-up and run a repository, implemented with case-based reasoning technology, for sharing project experience using an industrial-strength case study. The case study shows that it is both effective and efficient f...

Avoidance and discovery of security vulnerabilities in information systems and managing enterprises requires awareness of typical risks and a good understanding of vulnerabilities and threats and their exploitations. Various methods for characterizing, identifying and managing threats have been presented. Bruce Schneier has invented the Attack Trees, Microsoft call their method Threat Modeling ...

The soils affected by the spill of a pyrite mine were analysed in 100 sampling points at three depths (0-10, 10-30, and 30-50 cm) in 1998 (after the tailings were removed), 1999 (after the cleaning of the highly contaminated areas), and 2004 (after the tilling of the upper 20-25 cm). The comparative study reveals that the removal of the tailings left a heterogeneous distribution pattern of the ...

OBJECTIVE To evaluate the pathway of leaded dust from a lead-zinc-copper mine to houses of employees, and the impact on blood lead concentrations (PbB) of children. METHODS High precision lead isotope and lead concentration data were obtained on venous blood and environmental samples (vacuum cleaner dust, interior dustfall accumulation, water, paint) for eight children of six employees (and t...

This study characterises the total As concentrations and As bioaccessibility in 109 soils from Devon Great Consols Mine, an abandoned Cu-As mine in Devon, SW England, UK and discusses the soil and mineralogical factors that influence the bioaccessibility of this element. These data provide the basis for developing more accurate exposure estimates for use in human health risk assessments. The me...

Interactions between the MinD and MinE proteins are required for proper placement of the Escherichia coli division septum. The site within MinE that is required for interaction with MinD was mapped by studying the effects of site-directed minE mutations on MinD-MinE interactions in yeast two-hybrid and three-hybrid experiments. This confirmed that the MinE N-terminal domain is responsible for t...
