Growing freshwater scarcity in arid and remote areas usually is caused by the growth of population, urbanization and industrialization and the rather limited natural resources of potable water. In coastal belt of southwest region of Bangladesh, groundwater contains high salinity as well as excessive arsenic contamination. Though pond sand filter and rainwater harvesting system are usually used to...
Battery management systems can measure the performance of batteries. Most significantly, they can estimate expected run time under certain discharge conditions. The calculation is defined as the average current coming from the battery multiplied by the time it takes to reach a safe cutoff point of the battery. These two variables, average discharge current and duration, are directly proportional to...
Early detection is key to surviving breast cancer. The earliest indication of potential breast cancer detectable by current screening methods is the presence of microcalcifications. The low efficiency of ultrasound in detecting these microcalcifications is due to several factors, including the low spatial resolution of the ultrasound images and the speckle noise, which masks the tiny microcalcifications...
We used PIC18F452 microcontroller for hardware and software implementation of our home security system design. Based on PIC18F452, our system can monitor doors and windows of a house and can set alarm and warming signal to a nearest police station if anybody tries to break in. This security system also provides the functionality to identify the residents ID card to get access to the house without...
In this survey paper, we explore different medical imaging techniques used in the diagnosis of breast cancer. We compare their effectiveness, advantages, and disadvantages for detecting early-stage breast cancer. We mainly focuse on X-ray mammography, ultrasound, and magnetic resonance imaging (MRI), as they are the primary imaging modalities used in the clinic for the diagnosis of breast cancer.
Oxidation of ferrous ions by iron-oxidizing bacteria facilitates adsorption of arsenic on iron and subsequent co-precipitation. Based on this technique, a novel treatment process has been developed and tested under field conditions for simultaneous iron and arsenic removal from groundwater. In this study, a biological fixed bed reactor containing coconut husk and subsequent layers of iron matrix,...
