Research Progress on Carnation Etched Ring Virus

detection of carnation etched ring virus in greenhouses of khorasan razavi and northern khorasan provinces by elisa and pcr

in order to investigate the presence of carnation etched ring virus (cerv), samples of carnation (dianthus caryophyllus), sweet william (dianthus barbatus) and weed plants showing symptoms from greenhouses of khorasan razavi and northern khorasan provinces were collected in autumn 2009. polyclonal antiserum was used in order to detection of cerv by double- antibody sandwich-enzyme linked immuno...

first report of carnation vein mottle virus(cvmv)) infecting carnation in iran*

carnation (dianthus caryophyllus) can be infected by several viruses that some are specific to carnation flowers. vegetative propagation of carnation, can easily disperse viruses by infectied cuttings. during the year 2007, viral-like symptoms were observed on carnation in mahallat greenhouses. 142 suspected samples from glass houses, with symptoms of reddish- purple flecks and spots on leaves,...

InGaAsP/InP based Flattened Ring Resonators with Etched Beam Splitters

A novel flattened ring resonator design utilizing Etched Beam Splitters (EBS) in InGaAsP/InP is proposed and demonstrated. A multiple-thickness hard mask that compensates for RIE-lag realizes waveguides and EBS gaps in a single etch step. ©2009 Optical Society of America OCIS codes: 230.5750 Resonators, 250.5300 Photonic integrated circuits

Research Progress on Aging Mechanisms

Aging refers to a gradual process of functional and organic recession with the age increased after the organism maturing. Many researchers have tried to elucidate aging mechanism which includes the free radical theory: free radicals can become lipofuscin and cause the mutations of mitochondrial DNA (mtDNA), and the damage of the nuclear DNA. From the view of heredity, aging is the results of th...
