This paper is to study the effect of surface coating and silane hydrophobic agents for high performance concrete durability in a marine environment of tidal zone and splash zone by exposure test in JiaoZhou Bay. The results indicated that surface coating had good protection and coating quality after a 5-year period and the adhesive strength with concrete surface was more than 2.5 MPa. Surface c...

[1] Most analytical and numerical models developed to analyze pumping test data focus on saturated flow below the water table. Traditionally the soil above the initial water table prior to pumping has been thought to have little influence on the test results and has usually been ignored. It is hypothesized that, if the unsaturated zone is capped by low-permeability soil, airflow in the unsatura...

Background and Aim:  Streptococcus sanguinis (S. sanguinis) is one of the effective bacteria in the formation of caries and periodontal diseases which are caused by dental plaque. Currently, the use of natural honey (NH) is considered as a method of reducing S. sanguinis and S. mutans in saliva, which results in reducing the dental plaque. The purpose of this study was to evaluate the effects o...

OBJECTIVE We intended to calculate approximate fetal doses in pregnant women who underwent diagnostic radiology procedures and to evaluate the safety of their pregnancies. MATERIALS AND METHODS We contacted hospitals in different cities in Turkey where requests for fetal dose calculation are usually sent. Fetal radiation exposure was calculated for 304 cases in 218 pregnant women with gestati...

BACKGROUND Enteric fever caused by Salmonella enterica serovar Typhi (S. Typhi) is an important public health problem in developing countries like India.1 The emergence of resistance to fluoroquinolones has reduced the therapeutic options available. Currently, the uniform laboratory interpretation of ciprofloxacin and azithromycin susceptibility remains unclear. AIMS To study the antibiogram ...

This study was undertaken to compare and evaluate the antimicrobial efficacy of Biopure MTAD a root canal irrigant used for final rinse and commonly used intracanal medicament Metapex against Enterococcus faecalis and Propionibacterium acne .Agar disc diffusion test was done to compare and evaluate antimicrobial efficacy of Biopure MTAD (Dentsply Tulsa Dental, Tulsa, OK) and Metapex (META BIOME...

AIM The present study was conducted to evaluate the effcacy of commercially available herbal toothpastes against the different periodontopathogens. MATERIALS AND METHODS Six herbal toothpastes that were commonly commercially available were included in the study. Colgate herbal, Babool, Meswak, Neem active, Dabur red toothpastes were tested for the study whereas sterile normal saline was used ...

This paper presents two-dimensional laboratory experiments performed to study how groundwater flow may affect the injected air zone of influence and remedial performance, and how injected air may alter subsurface groundwater flow and contaminant migration during in situ air sparging. Tests were performed by subjecting uniform sand profiles contaminated with dissolved-phase benzene to a hydrauli...
