Biochar addition to soil can lead potential environmental risks due its content of polycyclic aromatic hydrocarbons (PAHs). Until now, previous research focused on assessing the influence pyrolysis peak temperature and feedstock formation evolution PAHs. Nevertheless, effects other important process parameters —such as pressure, gas residence time, type carrier gas— have not been comprehensivel...

This work highlights the ability of various cyanobacterial extracts from Anabaena spp., Tolypothrix Nostoc or Trichormus, among others genera, to control incidence damping-off caused by Pythium ultimum in cucumber seedlings. Protocols applied aimed at preliminary characterization collection were very useful for predicting their phytotoxic, phytostimulating and biopesticidal capacity. First, phy...

INTRODUCTION Fasciola hepatica, an endemic parasite common in Iraq and its neighboring countries, is a very rare cause of cholestasis worldwide. Humans can become definitive hosts of this parasite through their ingestion of a contaminated water plant, for example, contaminated watercress. Symptoms of cholestasis may appear suddenly and, in some cases, are preceded by long periods of fever, eosi...

Mediterranean rivers in intensive agricultural watersheds usually display outgrowths of macrophytes - notably alien species - due to a combination of high concentrations of nutrients in the water runoff and low flows resulting from water abstraction for irrigation. Standard mechanical and chemical control is used to mitigate the problems associated with excessive growth of plant biomass: mainly...
