This research assessed the adsorption of a pharmaceutical compound, ibuprofen, using rose geranium (Pelargonium graveolens L.) leaves to prepare low-cost activated carbon through orthophosphoric acid (H3PO4) activation. The from (AC-RGL) was characterized by TGA, SEM and FTIR. results were compared with those natural (Raw-RGL). influence chemical parameters for uptake ibuprofen on both adsorben...

Peat is the most common substrate used in nurseries despite being a very expensive and a non-renewable material. Peat replacement with biochar could be a sound environmental practice, as it is produced from waste biomass, but evaluation of biochar as a potting substrate is needed. Ratios of peat:biochar of 100:0, 70:30, 30:70 (BC0, BC30, and BC70, respectively), two fertilizer rates (FERT1, FER...

This paper presents a new application of the normal mode decomposition to measure the reflection and absorption coefficients of a low growing living plant in a large 300 300 mm impedance tube. In this way the higher frequency limit can be extended by a factor of 3 in comparison to that suggested by the standard ISO 10534-2 method for this type of an impedance tube. The adopted method (Prisutova...

UNLABELLED Pelargonium L. genra (Fam. Geraniaceae) includes over 250 species, most of it native to southern Africa. Nowadays, four perennial species are cultivated in Romania as ornamental plants. Our aim was to establish the main characteristics and differences that occur between Pelargonium zonale, P. hispidum, P. grandiflorum, P. peltatum and P. radens. All in all, the quantitative differenc...

Commercial vegetative propagation of oricultural crops requires the segregation of plant cuttings into categories based on size. The cuttings however must be graded when they are planted ("stuck"), at which time the grade of a cutting is not easy to determine. This paper reports on a system that learns to classify cuttings from being shown examples of images of cuttings that have been graded by...

We evaluated the efficacy of commercial antimosquito products in field trials in Illinois in June 1998 by comparing mosquito landing rates. Products tested were a sonic mosquito repeller, an insect killing grid using ultraviolet light and 1-octen-3-ol as lures, mosquito smoke coils containing a pyrethroid, citronella candles, the mosquito plant Pelargonium citrosum, and a N,N-diethyl-3-methylbe...

Pelargonium graveolens (Geranium) is a source of the finest quality fragrance and its essential oils are used as antibacterial, antifungal agents. The aim current research to determine chemical constituents in oil P. by GC-MS evaluate antidiabetic activity via α-glucosidase inhibition assay. composition was determined GC/MS assessed through enzyme in-vitro models. analysis determines 36 compone...

Geraniaceae plastid genomes are highly rearranged, and each of the four genera already sequenced in the family has a distinct genome organization. This study reports plastid genome sequences of six additional species, Francoa sonchifolia, Melianthus villosus, and Viviania marifolia from Geraniales, and Pelargonium alternans, California macrophylla, and Hypseocharis bilobata from Geraniaceae. Th...

A plant recently introduced into North America as the citrosa, Pelargonium citrosum ('Van Leenii'), has been marketed as a biological repellent against mosquitoes. Citrosa is claimed to repel mosquitoes within a 10 ft.2 (0.93 m2) area due to a continuous fragrant release of citronella oil. The total essential oil yield was 0.2 +/- 0.1% from fresh plant material. Chemical analysis by the authors...
