Study on total residual oxidant decay in long-distance seawater intake pipeline of cooling system.

Electrochlorination is often used for biofouling control along the water intake pipeline of seawater cooling system, but with the increasing of pipeline length, this process needs to be further improved. In this study, the dynamic circulation and field pilot test were used to simulate the long-distance seawater intake pipeline, investigating total residual oxidant (TRO) decay and its influencing factors by comparing the bench test. The results showed that intermediate dosing could increase terminal TRO, but also reduce the CT value, resulting in decline of local inactivation effect.

Application of gene chip technology in the diagnostic and drug resistance detection of Helicobacter pylori in children.

Background And Aims: Helicobacter pylori (HP) culture for diagnosing HP infection is time-consuming and technologically complex. This study evaluated the clinical significance of gastric mucosal gene chip technology in the rapid diagnosis of HP infection and detection of drug resistance in children.

Methods: Patients (between the age of 2.

Antibiotics resistance of Helicobacter pylori in children with upper gastrointestinal symptoms in Hangzhou, China.

Background: The decreasing eradication rate of Helicobacter pylori is mainly because of the progressive increase in its resistance to antibiotics. Studies on antimicrobial susceptibility of H. pylori in children are limited.

Investigation of Helicobacter infection among symptomatic children in Hangzhou from 2007 to 2014: a retrospective study with 12,796 cases.

Background And Aim: The infection of Helicobacter (H. ) is acquired in childhood and the prevalence vary greatly in different countries and regions. The study aimed to investigate the characteristics of H.
