Sažetak – Prepoznavanje lica jedno je o najuspješnijih primjena analize slike i kao takvo si je priskrbilo dosta pažnje i proučavanja zadnjih godina. Razlog tome su razne komercijalne i policijske primjene kao i raspoloživost upotrebljivih tehnologija. Iako su današnji sustavi za prepoznavanje lica dosegli odreñenu zrelost postoji još otvorenih problema. Prepoznavanje u nekontroliranim uvjetima...

This study was carried out to evaluate the antimicrobial and antioxidant activities of different extracts from aerial parts of six Salvia species including Salvia ceratophylla, Salvia chorassanica, Salvia leriifolia, Salvia macrosiphon, Salvia chloroleuca and Salvia virgata. The effect of the extracts against 3 Gram positive and 3 Gram negative bacteria was tested by the micro dilution method. ...

The essential oil composition and genetic variability of common sage ( Salvia officinalis L.) and its three ornamental cultivars ('Purpurascens', 'Tricolor', and 'Kew Gold') as well as Judean sage ( Salvia judaica Boiss.) were analyzed by GC-FID, GC-MS, and random amplified polymorphic DNA (RAPD). Common sage and its cultivars contained the same volatile compounds; only the ratio of compounds d...

Three kinds of polyphenols of Salvia miltiorrhiza Bunge, 3,4-dihydroxyphenyllactic acid, salvianolic acid B and protocatechualdehyde, were separated and purified in one step with solvent system n-hexane-ethyl acetate-methanol-acetic acid-water (1:6:1.5:1.5:8) by high-speed counter-current chromatography. Acetic acid was successfully used to increase the partition of high polar target compounds ...

s:1381:"Background: Studies show that Salvia officinalis administration can influence reproductive functions in animals. The purpose of this study was to determine the effects of Salvia officinalis extract on serum levels of testosterone and testes tissue differentiation in male rats. Materials and Methods: Male Wistar rats were randomly divided into control, normal saline, and Salvia officinal...

The antimicrobial activity of three Salvia species, i.e. S. santolinifolia, S. hydrangea and S. mirzayanii, essential oils were investigated. The essential oils were obtained from the aerial parts of plants and analyzed by GC-MS. The main constituents of aforementioned species were alpha-pinene (72.4%), beta-pinene (6.6%) and limonene (5.3%); beta-caryophyllene (25.1%), 1,8-cineol (15.2%) and c...

In order to define the phytotoxic potential of Salvia species a database was developed for fast and efficient data collection in screening studies of the inhibitory activity of Salvia exudates on the germination of Papaver rhoeas L. and Avena sativa L.. The structure of the database is associated with the use of algorithms for calculating the usual germination indices reported in the literature...
