Background: Car wash wastewater contains several contaminants such as organic matter, oil, grease, detergents and phosphates, all of which are harmful for the environment. In this study, the application of electrocoagulation (EC) to treat car wash wastewater has been studied, and the operating parameters optimized. The electro-Fenton (EF) for further contaminant removal was also investigated. ...
Eating frequently during the day, or "grazing," has been proposed to assist with managing food intake and weight. This systematic review assessed the effect of greater eating frequency (EF) on intake and anthropometrics in human and animal experimental studies. Studies were identified through the PubMed electronic database. To be included, studies needed to be conducted in controlled settings o...
Ethyl formate (EF) in combination with CO2 was tested for control of arthropods commonly infesting California table grapes. In addition, table grape tolerance to EF exposure was evaluated. LC99 estimates were developed for target pests by using a range of EF concentrations (0.04-4.7% EF). Response to treatments varied greatly between species, as well as life stages within species. Western flowe...
PURPOSE To compare multidetector computed tomography (MDCT) and two-dimensional transthoracic echocardiography (2DE) for left ventricular ejection fraction (EF); and to make comparison between reconstructions of 1-mm and 2-mm slice thickness at MDCT in left ventricular analysis by using a semiautomated segmentation algorithm. MATERIALS AND METHODS In 43 patients global left ventricular systol...
