Tanzania has recently experienced a significant rise in the burden of diabetes, and it is estimated that more than 400,000 people are living with diabetes. A major concern management diabetes occurrence diabetic complications occur as result poor glycemic control. Identification factors associated control important order to institute appropriate interventions for purpose improving prevention chronic complications.The aim this study was determine level explore among patients type 2 mellitus...

The feasibility of training an artificial neural network (ANN) for accurately predicting transient water levels in a complex multilayered ground-water system under variable state, pumping, and climate conditions is demonstrated. Using real-world data, ANN was developed public supply wellfield monitoring located near Tampa Bay, Florida. trained to predict at 12 well locations screened different aquifers response changing pumping conditions. then validated with ten sequential seven-day...

Infiltration of storm water through detention and retention basins may increase the risk groundwater contamination, especially in areas where soil is sandy table shallow, contaminants not have a chance to degrade or sorb onto particles before reaching saturated zone. Groundwater from 16 monitoring wells installed southern New Jersey was compared quality shallow 30 new-urban land use. Basin contained much lower levels dissolved oxygen, which affected concentrations major ions. Patterns...

A comprehensive hydro-ecological investigation was conducted to determine the ecological response of increased groundwater withdrawals from Kirkwood-Cohansey aquifer system, an important source water supply in southern New Jersey, USA. Collocated observations were made aquatic-macroinvertebrate assemblages and stream hydrologic attributes develop flow–ecology relations. sub-regional transient flow model (MODFLOW) used simulate three plausible high-stress groundwater-withdrawal scenarios...

Atmospheric methyl tert‐butyl ether (MTBE) concentrations in southern New Jersey generally exceeded samples taken from the unsaturated zone. A simple zone transport model indicates that MTBE degradation can explain attenuation with half‐lives a few months to couple of years. Tert‐butyl alcohol (TBA), possible product MTBE, was detected unsaturated‐zone at exceeding atmospheric levels some sites, suggesting conversion TBA. At sites where shallow groundwater, concentration typically higher...

The Kirkwood-Cohansey aquifer system is an important source of present and future water supply in southern New Jersey. Because this unconfined also supports sensitive wetland aquatic habitats within the Jersey Pinelands (Pinelands), managers policy makers need up-to-date information, data, projections that show effects potential increases groundwater withdrawals on these habitats. Finite-difference flow models (MODFLOW) were constructed for three drainage basins (McDonalds Branch Basin, 14.3...
