The present paper studies the content of heavy metals: Fe, Mn, Zn, Cu, Pb, Ni and Cd in the foliage of an indicator plant dandelion as collected from the lawns and parks of the Warsaw metroplitan area. The results suggest heavy accumulation of Fe, Zn, Pb and Cd as a consequence of the impact of traffic-born pollution. Keywords! dandelion, indicator plant, zinc, copper, iron, lead, cadmium, poll...

AIM Herbal plants and their derived products are extensively used particularly in many Asian, African, and other countries of the world as they are considered as ideal feed additives because of their non-residual effect and ability to influence the ecosystem of gastrointestinal microbiota in a positive way. Further, the enzymatic treatment of these herbs helps in their efficient utilization by ...

In this paper we study the problem of shape from silhouette outlines (SFO) using a novel adaptive dandelion model. SFO reconstructs a 3D model using only the outmost silhouette contours and produces a solid called the ‘‘bounding hull’’. The dandelion model is composed of a pencil of organized line segments emitted from a common point which samples the bounding hull surface in regularly distribu...

We consider the class of Dandelion-like codes, i.e., a class of bijective codes for coding labeled trees by means of strings of node labels. In the literature it is possible to find optimal sequential algorithms for codes belonging to this class, but, for the best of our knowledge, no parallel algorithm is reported. In this paper we present the first encoding and decoding parallel algorithms fo...

We tested for ecological differences among apomictic dandelion genotypes in Vancouver, British Columbia, Canada, in order to establish a basis for predicting potential ecological consequences of genetic variation in invading populations. A greenhouse experiment on 30 potential clonal families revealed significant among-family variation for leaf morphological traits, and molecular analyses confi...

Inspired by the behavior of dandelion sowing, a new novel swarm intelligence algorithm, namely, dandelion algorithm (DA), is proposed for global optimization of complex functions in this paper. In DA, the dandelion population will be divided into two subpopulations, and different subpopulations will undergo different sowing behaviors. Moreover, another sowing method is designed to jump out of l...

Ethnomedicinal knowledge of plant-derived bioactives could help us in discovering new therapeutic compounds of great potential. Certainly, dandelion has been used in traditional ethno-medicinal systems (i.e., Chinese, Arabian, Indian, and Native American) to treat different types of cancer. Though, dandelion is highly vigorous, but the potential mode of action is still unclear. In the current s...

Content distribution via the Internet is becoming increasingly popular. To be cost-effective, commercial content providers are considering the use of peer-to-peer (P2P) protocols such as BitTorrent to save on bandwidth costs and to handle peak demands. However, when an online content provider uses a P2P protocol, it faces a crucial issue: how to incentivize its clients to upload to their peers....

Reliable message propagation is an important means of communication in mobile ad hoc networks (MANETs), and serves as a fundamental component for various applications, such as mobile advertising, inter-vehicle safety message propagation, alert propagation to defend against cyber-attacks in MANETs. Reliable message propagation requires that a message can be delivered to a large percent (e.g. 90%...
