Therefore, the oil/water co-production duration of Well D1 was long and its oil recovery was relative high.
Finally, its effectiveness is verified through the development of a prototype application for the optimization of the duration of well production tests.
The average duration of well use for wells with a known arsenic concentration accounted for 25% of lifetime for both sexes (Ahsan et al. 2006b).
At the baseline interview for each participant, information on daily water consumption and duration of well use was collected for wells used on a regular basis.
A further risk factor for a poorer outcome might be the diagnosis bipolar II disorder with more and longer duration of episodes and shorter duration of well intervals than in bipolar I patients [ 5].
Well arsenic was not associated with duration of well use, sex, smoking status, age, BMI, educational attainment, treatment duration, treatment assignment, urinary arsenic at follow-up, or changes in urinary arsenic.
Based on well utilization history, we calculated the CAI, which is the sum of the products of the amount of water consumed per day (liters per day) × As concentration in the well(s) (milligrams per liter) × the duration of well use (days) for each well (Ahsan et al. 2006b).
We found no significant differences between the participating and nonparticipating families in the sociodemographic factors sex of the child, mother's age and educational attainment, number of living siblings, land or television ownership, duration of well use, or WAs concentration (data not shown).
This enables additional endocrine agents to be used sequentially, with the aim of extending the effective duration of well-tolerated treatment before cytotoxic chemotherapy becomes necessary (Carlson, 2002).
Although the prevalence of pterygium increased with the duration of artesian well water consumption, participants who had consumed artesian well water for ≥ 30 years had a risk similar to that of those who had consumed the water for 20 29 years.
