A survey to evaluate the association between blood lead level and blood pressure among workers employed in factory manufacturing lead acid-storage batteries
Background: There are many controversies reported about the association between blood lead levels and blood pressure among lead exposed workers. Studies have suggested incorporating lifestyle factors along with blood lead levels. The present study aimed to evaluate the effect of lead exposure on blood pressure changes among lead exposed workers in contemplation of lifestyle factors. Mater...
متن کاملEvaluation of total and differential white blood cell counts in workers exposed to lead
Introduction: Lead is a toxic heavy metal that has adverse health effects on blood parameters. About 80% of lead produced is used in batteries, especially vehicle batteries. Therefore, the present study aimed to assess the hematological changes, including total and differential white blood cell (WBC) counts in battery workers exposed to lead, and compare with the non-exposed group. Materials a...
متن کاملDevelopment of Lifetime Prediction Model of Lithium-Ion Battery Based on Minimizing Prediction Errors of Cycling and Operational Time Degradation Using Genetic Algorithm
Accurate lifetime prediction of lithium-ion batteries is a great challenge for the researchers and engineers involved in battery applications in electric vehicles and satellites. In this study, a semi-empirical model is introduced to predict the capacity loss of lithium-ion batteries as a function of charge and discharge cycles, operational time, and temperature. The model parameters are obtai...
متن کاملAn Investigation on the Behavior of Retaining Structure of Excavation Wall Using Obtained Result from Numerical Modeling and Monitoring Approach. (A Case Study of International "Narges Razavi 2 Hotel", Mashhad)
With the growing population and density in metropolitan areas, higher tendency to live in high-rise buildings, and increasing demand for parking lots, it seems necessary to excavate soil to construct underground spaces. During excavation work, as the height of the wall increases, special care should be taken to the wall stabilization to avoid any consequent damage including extensive property d...
متن کاملInitial Discharge Capacity of Manganese Cobaltite as Anode Material for Lithium Ion Batteries
Nanostructured manganese cobalt oxide spinel (MnCo2O4) are prepared by co-precipitation method and calcined at 650 and 750°C. Morphological studies show that by increasing the calcination temperature from 650 to 750°C, morphology of the particles changes from quasi-plate to polyhedral. The MnCo2O4 calcined at 650°C could deliver an initial discharge capacity of 1438 mAh g-1 under current densit...
