Floral nectaries of basil (Ocimum basilicum): Morphology, anatomy and possible mode of secretion
(Elsevier Science Bv, Amsterdam, 2007)
Floral nectaries of Ocimum basilicum L. were studied using light, fluorescence and scanning electron microscopy. Each nectary forms an asymmetrical four-lobed disc at the base of the outer surface of the ovary. The three ...
Extraction of useful metals from lead-silver cake in the process of hydrometallurgical zinc production by leaching in calcium-chloride solution
(Bulletin of Electrochemistry, 2006)
This paper shows the result of examining lead, silver cadmium and copper extraction from lead-silver waste cake in the process of hydrometallurgical zinc production. Besides controlling of pH value, the lead-silver cake ...
Comparison of the swelling kinetics of a partially neutralized poly(acrylic acid) hydrogel in distilled water and physiological solution / Poređenje kinetike bubrenja hidrogela delimično neutralisane poli(akrilne) kiseline u destilovanoj vodi i fiziološkom rastvoru
(Srpsko hemijsko društvo, Beograd, 2007)
The isothermal kinetics curves of the swelling of a poly(acrylic acid) hydrogel in distilled water and physiological solution at temperatures ranging from 20 to 40 ºC were determined. The possibility of applying both the ...
Variability of Essential Oil Composition of Cultivated Feverfew (Tanacetum parthenium (L.) Schultz Bip.) Populations
(Journal of Essential Oil Research, 2009)
The differences in essential oil composition, based upon GC and GC/MS analysis, were studied in four cultivated populations of Feverfew (Tanacetum parthenium (L.) Schulz Bip.). The yield of oil ranged from 0.23% to 0.36%; ...
