detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

EIGHT NEW OR LESS KNOWN MITOSPORIC FUNGI FOR IRAN MYCOFLORA FROM GUILAN PROVINCE, N. IRAN

During a study several species of mitosporic fungi which have been collected from Guilan Province were examined and seven species viz.: Hansfordia pulvinata, Myriellina cydoniae, Phloeospora cf. ulmi, Questieriella sp., Sarcinella questieri, Septoria cf. castaneicola and Sirosporium mori were found to be new records for Iran mycoflora. Moreover, Sirosporium celtidis is described and illustrated...

A New Paradigm in Biology – The Effect of Localization of a Protein on its Anti-genicity

Generating New Perfect Fluid Solutions from Known Ones

Stationary perfect uid con gurations of Einstein's theory of gravity are studied. It is assumed that the 4-velocity of the uid is parallel to the stationary Killing eld, and also, that the norm and the twist potential of the stationary Killing eld are functionally independent. It has been pointed out earlier by one of us (I.R.) that for these perfect uid geometries some of the basic eld equatio...

Generating new perfect-fluid solutions from known ones: II

The properties of a transformation previously considered for generating new perfect-fluid solutions from known ones are further investigated. It is assumed that the four-velocity of the fluid is parallel to the stationary Killing field, and also that the norm and the twist potential of the stationary Killing field are functionally related. This case is complementary to the case studied in our p...
