In this paper, we review the peer-to-peer blockchain transaction protocol, Dandelion, and develop an oracle-based model for its network security. We formalize a series of security functional criteria, such as unforgeability, non-repudiation, immutability, into experiments. our model, consider quantum-capable adversary who seeks to undermine any criteria while using oracles simulate interact wit...

to examine metal content of dandelion plants in relation to environmental metal levels,concentrations of cd, hg and pb were analyzed in plant parts (leaves and roots) and soil samples from fivesites in the city of brno (czech republic), differentially impacted by pollution. soils and plants werecollected mid-april 2011. atomic absorption spectrometry was used to determine concentrations of thes...

The objective of the study was to evaluate the effect of inulin or dandelion, chicory and Jerusalem artichoke powder on lipid indices and fatty acid profile in fattener tissues. The experiment involved 120 crossbred pigs (PL x PLW) x Duroc with an initial body weight of 25.0 +/- 0.5 kg. Animals were assigned into 6 groups. A diet for group I (control) did not comprise an inulin additive, group ...

Flower visits are complex encounters, in which animals are attracted by floral signals, guided toward the site of the first physical contact with a flower, land, and finally take up floral rewards. At close range, signals of stamens and pollen play an important role to facilitate flower handling in bees, yet the pollen stimuli eliciting behavioral responses are poorly known. In this study, we t...

Dandelion (Taraxacum officinale L. Weber ex F.H. Wigg.) roots were traditionally used in folk medicine worldwide due to its antidiabetic, choleretic, antirheumatic and diuretic properties. The aim of the current study was to determinate the biologically active substances in 95% ethanol and subsequent water extracts from dandelion roots and to evaluate their antioxidant activities. The carbohydr...

To address the role of insect herbivores in adaptation of plant populations and the persistence of selection through succession, we manipulated herbivory in a long-term field experiment. We suppressed insects in half of 16 plots over nine years and examined the genotypic structure and chemical defense of common dandelion (Taraxacum officinale), a naturally colonizing perennial apomictic plant. ...

Dandelion (Taraxacum officinale), a member of the Asteraceae (Compositae) family, is well known as traditional medical plant. polysaccharides, natural active ingredient extracted from dandelion, possess immune regulation, anti-inflammatory, antioxidant, and anti-aggregation properties. These properties suggest that dandelion polysaccharides might alleviate atherosclerosis. Using an ApoE−/− athe...

Major chloroplast pigments in five leafy vegetables (chicory-Cichorium intybus, cv. 'Anivip' and cv. 'Monivip', dandelion-Taraxacum officinale, garden rocket-Eruca sativa and wild rocket-Diplotaxis tenuifolia), commonly consumed in Mediterranean countries, have been separated by high-performance liquid chromatography (HPLC) on a reversed-phase column. Three classes of pigments were identified a...
