The aim of the study is to assess the evolving mine water quality of closed uranium mines (abandoned between 1958 and 1992) in the Czech Republic. This paper focuses on the changes in mine water quality over time and spatial variability. In 2010, systematic monitoring of mine water quality was performed at all available locations of previous uranium exploitation. Gravity flow discharges (mine a...

In this note we show that a closed Riemannian manifold does not admit fill-in with nonnegative scalar curvature if the mean is point-wise large. Similar result also holds for fill-ins negative lower bound.

The cost of this wall of codes is clear for managers: They must fill out endless forms—repeatedly explaining their safety procedures, overtime rules, and so forth. In addition, they must host endless visits from compliance auditors. Less obviously, the wall of codes is costly for consumers and other stakeholders who care about the social performance of businesses. Not only must they pay the (pa...

The theme?that of the cause and course of alcoholism ln a personality of refinement?is handled with insight and knowledge, sympathy and toleration, and built up without either sentimentality or sensationalism. Events move quickly but carry conviction, the style is impersonal and the descriptions succinct. To sticklers, the us...

The focus of this paper is effective health education and promotion in the field of mine awareness, or what has more recently been re-titled 'mine risk education'. According to the United Nations, mine risk education comprises educational activities that aim to reduce the risk of injury from landmine/unexploded ordnance (UXO) through raising awareness and promoting behavioural change and includ...

The majority of existing automatic mine detection algorithms which have been developed are robust at detecting mine-like objects (MLOs) at the expense of detecting many false alarms. These objects must later be classified as mine or not-mine. The authors present a model based technique using Dempster–Shafer information theory to extend the standard mine/not-mine classification procedure to prov...

As asteroid mining projects break through the technical barriers, more countries have plan to become pioneers. However, world currently does not a complete policy ensure that can benefit all of humanity. Therefore, exploring its fairness and normality needs be on agenda. AHP EWM are used construct global fair distribution model is in line with "global interests." It defined as fairness" from pe...

In this paper, a method of mathematical modeling for solving the problem reusing man-made waste from mining and processing ores is proposed. The use intermediate products (man-made waste: tailings plants, rocks sinking operations technical water mine drainage) in cyclic production presupposes their as fill material components placement mined-out voids underground mines. influence factors on com...
