Background: Fusion of Hepatitis B virus surface antigen (HBsAg) to Polaris P70 a DNA construct might be considered as a strategy to enhance cellular and cytotoxic T-lymphocytes (CTL) responses of a Hepatitis C Virus core protein (HCVcp)-based DNA vaccine comparable to that of adjuvanted protein (subunit) immunization.Materials and Methods: pCHCORE
Optimization of ultrasonic extraction and analyses methodology by HPLC for determination of diuron and its metabolites in soil cultivation of sugar cane
Diuron, N-(3,4-dichlorophenyl)-N, N-dimethylurea can be transformed into the soil through the biodegradation of 3-(3,4-dichlorophenyl)-3-methylurea (DCPMU), 3.4-diclorofenilureia (DCPU) and 3,4-dichloroaniline (DCA).This study aimed to optimize and validate a method of extraction and analysis of these substances in the soil by HPLC/DAD.There was ex
Concrete relative velocity prediction to prevent mortar segregation for safe gravity transportation
Concrete mortar segregation during vertical pipeline gravity transportation will form a weak part in the shaft lining, which poses a challenge for deep mine shaft safety.The specific gravity difference between aggregate and slurry will cause relative motion; the relative velocity is detrimental to the mortar workability, which plays a significant r
