Depth and Well Type Related to Groundwater Microbiological Contamination
Use of groundwater from private wells in households has increased considerably, owing to a better cost/benefit ratio than that of water provided by local utilities for a fee. However, this water is usually untreated, which makes it a vehicle for diseases. Thus, monitoring this water is necessary to ensure its integrity and quality. We aimed to evaluate the physical, chemical, and microbiologica...
متن کاملPumping Electron-Positron Pairs from a Well Potential.
In the presence of very deep well potential, electrons will spontaneously occupy the empty embedded bound states and electron-positron pairs are created by means of a non-perturbative tunneling process. In this work, by slowly oscillating the width or depth, the population transfer channels are opened and closed periodically. We find and clearly show that by the non-synchronous ejections of par...
متن کاملAnalytical model for computing residence times near a pumping well.
An analytical solution for calculating the residence time of fluid flowing toward a pumping well in an unconfined aquifer has been developed. The analytical solution was derived based on a radial, steady-state, Dupuit-Forchheimer flow model. The resulting integral expression involved computing the imaginary error function, for which a simple series expansion is proposed. The validity of the ana...
متن کاملThe Pumping Lemma for Well-Nested Multiple Context-Free Languages
Seki et al. (1991) proved a rather weak pumping lemma for multiple context-free languages, which says that any infinite m-multiple context-free language contains a string that is pumpable at some 2m substrings. We prove a pumping lemma of the usual universal form for the subclass consisting of well-nested multiple context-free languages. This is the same class of languages generated by non-dupl...
متن کاملHydrologic-Economic Optimization of a Brackish Coastal Pumping Well
Saltwater intrusion and upconing phenomena affect coastal aquifers worldwide. Over-exploitation leads to high salinity levels which threaten sustainable use of these freshwater resources. There is an increasing need to accurately, and practically, model the physics of these coastal pumping systems while also incorporating the relevant economics. We formalize a decision model able to define the ...
