Whenever, there will be onset of lignite extraction, there will be always a threat of sea water intrusion into the mining lease area due to its close proximity to seashore.

متن کاملAlluvion – A Language for Computer Arithmetic Algorithms
Computer arithmetic algorithms usually are represented by circuit diagrams which do not seem to be the first choice for algorithms. Rather, this is a consequence of the fact that these algorithms are implemented as circuits in almost all cases. However, it is possible to represent these algorithms in a procedural way, as is shown in this work. A specialized programming language is developed to ...
