Energy efficiency in a building complex through seasonal storage of thermal energy in a confined aquifer
Confined aquifers are formations surrounded by impermeable layers called cap rocks and bed rocks. These aquifers are suitable for the seasonal storage of thermal energy. A confined aquifer was designed to meet the cooling and heating energy needs of a residential building complex located in Tehran, Iran. The annual cooling and heating energy needs of the buildings were estimated to be 8.7...
متن کاملAn Assessment of Factors Affecting Reactive Transport of Biodegradable BTEX in an Unconfined Aquifer System, Tehran Oil Refinery, Iran
Risk-based assessment methods are commonly used at the contaminated sites by hydrocarbon pollutants. This paper presents the results of a two-dimensional finite volume model of reactive transport of biodegradable BTEX which have been developed for the saturated zone of an unconfined aquifer in the Pump station area of Tehran oil refinery, Iran. The model governing equations were numerically sol...
متن کاملEvaluation of Efflux pump activity among Uropathogenic Escherichia coli and Klebsiella pneumonia multiple- Drug Resistance isolates
Antibiotic resistance is a phenomenon in which antibiotic used to treat bacteria becomes useless due to resistance mechanism. Increased drug resistance and occurrence of Multiple Drug Resistance in bacteria specificity nosocomial and Urinary Tract Infection bacteria has reduced the possibilities of treating these infectious diseases. Efflux pumps are one of the major mechanism of MDR in bacteri...
متن کاملSimulation-based Vibration Sensor Placement for Centrifugal Pump Impeller Fault Detection
In this paper, a simulation-based method is proposed for optimal placement of vibration sensors for the purpose of fault detection in a centrifugal pump. The centrifugal pump is modeled to investigate the effect of vane tip fault on fluid flow patterns numerically. Pressure pulsations are investigated at different locations at the inner surface of the pump before and after the presence of the f...
متن کاملProviding DRASTIC maps to assess potential vulnerability in Kohnak aquifer using GIS
Nowadays the study of regional groundwater resources, because of draught ,their optimal exploitation,and reducing their pollution is a vital matter. A proper way to prevent the pollution of undergroundwaters is to locate vulnerable spots and to conduct an efficient exploitation of the ground. Using thepresent models is very essential to locate and study about vulnerable spots. For this study, G...
