The scale removing process with acid, generally called as the pickling process, is accepted by steel producers satisfactorily. However, most of tend to develop without acid due environmental regulations. In related literature, some methods were studied for finding eco-friendly solutions. Although these studies seem be promising, still dominant a descaling before cold rolling applications. this ...
Background & Aim: Corrosion is one of the most complicated and costly problems related to the drinking water supply that can influence the health of consumers, the general acceptance of a water resource, and the costs of water supply. Scaling also causes problems such as clogging and head loss in drinking water networks. The aim of this study was to determine the chemical quality and stability ...
abstract background: corrosion and scaling are of the most important characteristics of drinking water, affecting public health and water industry economy. the aim of the present study was to evaluate the corrosion and scaling potential of potable water supplied by saqqez rural water and wastewater company. materials and methods: this was a descriptive study conducted on 142 samples taken from ...
breeding programs strategies depends on genetical mechanism of selection traits. in the present research, generation mean analysis with joint scaling test was performed to determine the gene action. f1, f2 and f3 generations, derived from roushan and kavir cross along with their parents were sown in a partial lattice design with two replications under stress condition at the research field of s...
statement of the problem subgingival irrigation with an antimicrobial agent after scaling and root planing (srp) is assumed to be able to kill the bacteria left behind after mechanical debridement. 3% h2o2 is used in the treatment of periodontal disease and it has been shown effective in killing anaerobic pathogens. purpose the aim of this study was to evaluate the clinical effects of subgingiv...
Background & purpose: One of the major factors in the quality of drinking water is corrosion and scaling. The aim of the present study was to evaluate corrosion and scaling potential of drinking water supply network in Juybar (A city in Iran). Materials and Methods: 60 samples of drinking water in distribution network were collected randomly in summer and autumn seasons and transferred into ...
Introduction: Corrosion and scaling are important factors affecting drinking water quality, causing health and economic problems. This study aimed to investigate the indicators of corrosion and scaling in Rafsanjan drinking water. Materials and Methods: The present descriptive cross-sectional study was conducted in winter 2018 and spring 2019 in Rafsanjan. The 56 samples were randomly taken fr...
