The aim of the study was to investigate and compare heavy metals (Cu, Pb Zn) concentrations in Festuca rubra three groups grassy ecosystems with different anthropopressive risk (A ecosystem - urban soils, B rural C roadside soils). strongest pollution recorded for grass A ecosystems. They were caused mainly by presence which their significantly exceeded critical values plants confirming unequiv...
Traditional wireless Medium Access Control (MAC) protocols suffer from a number of drawbacks when used in vehicle to roadside networks. This paper proposes an efficient MAC protocol that addresses a number of critical aspects required for MAC protocols for vehicle to roadside networks including elimination of hidden terminals, prioritized and fast handoff, fairness among nodes and optimal choic...
Node authentication in VANETs is one of the most important research topics nowadays. VANETs present unique challenges such as high node mobility, real-time constraints, scalability, gradual deployment and privacy. No existent technique addresses all these requirements. In particular, both inter-vehicle and vehicle-to-roadside wireless communications present different characteristics that should...
The data presented in this article are related to the paper "Prevalence of psychoactive substances, alcohol and illicit drugs, in Spanish drivers: A roadside study in 2015". (https://doi.org/10.1016/j.forsciint.2017.07.005) Domingo-(Salvany et al., 2017) [1]. In that paper it was not possible to directly compare 2015 results with previous editions for various reasons, one of which was the lack ...
The concentration of heavy metals in plants’ leaves can effectively indicate the spatiotemporal differences environmental pollution, providing a scientific basis for monitoring urban air quality. Ni, Cu, Cd, Pb and Zn five different species (Ophiopogon japonicus, Ligustrum vicaryi, Platanus acerifolia, Sophora japonicaand Cedrusdeodara) were measured, which from I, II, III, IV (0.05 m, 0.25 1 4...
In Jeddah governorate, increased industrialization, urbanization and vehicular traffic may raise levels of heavy metals in the air soil, threatening food safety human health. Roadside vegetation barriers might be an effective way to enhance roadside quality reduce exposure pollution. This study was conducted order uncover best-cultivated plant species for purifying polluted terms environmental ...
Road reserves have a rich history of human impacts, and are important social, economic and ecological component of agricultural landscapes in Australia. Road verge, or roadside environments are gaining greater recognition for their role in nature conservation. In Australia, road reserves are areas of public land retained for the development of future roads. Many road reserves were originally su...
Two on-farm commercial vegetable demonstrations were conducted in south-central Kentucky, along with three specialty melon observation plots in 2003. Grower/cooperators were located in Edmonson and Larue counties. The grower/cooperator in Edmonson County grew one acre of cantaloupes, marketed through Green River Produce Marketing Cooperative located in Horse Cave, Kentucky. In Larue County, the...
Particulate matter (PM) is the most dangerous air pollutant that adversely affects health. Increasing PM in urban areas a big problem must be solved. This study analyzed amount of accumulated on plant leaves, as well leaf traits contribute to accumulation, determine plant’s ability accumulate and impact plants. Scanning electron microscopy (SEM) energy dispersive X-ray (EDX) analysis were used ...
