This research aims know determine Estuary using STORET method pollution index (IP). study used survey m...
The continuous and widespread deterioration of lake water quality eutrophication is not only a local problem, but also global phenomenon [...]
We describe a quantum system consisting of a one-dimensional linear chain of n identical harmonic oscillators coupled by a nearest neighbor interaction. Two boundary conditions are taken into account: periodic boundary conditions (where the nth oscillator is coupled back to the first oscillator) and fixed wall boundary conditions (where the first oscillator and the nth oscillator are coupled to...
the zarivar lake a freshwater lake in west of kurdistan province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. the present study aimed at evaluation of the zarivar lake using nsf- wqi as an indicator of water quality. wqi is a suitable tool to examine and classify spatial and temporal varia...
BACKGROUND There are several suspected environmental risk factors for non-Hodgkin lymphoma (NHL). The associations between NHL and environmental chemical exposures have typically been evaluated for individual chemicals (i.e., one-by-one). OBJECTIVES We determined the association between a mixture of 27 correlated chemicals measured in house dust and NHL risk. METHODS We conducted a populati...
