Biomass and carbon stock in a forested areas are now prime important indicators of forest management climate change mitigation measures. But the accurate estimation biomass trees forests is challenging issue. In most cases, pantropical regional models used frequently to estimate trees, but these estimations have some uncertainty compared species-specific allometric model. Acacia nilotica, Casua...

Wood is a magnificent natural resource that can be regarded as the single most important of future. Eucalyptus camaldulensis and Melia azedarach trees were introduced in Iraq planted ornamental at parks streets. A study branch wood was conducted order to identify its basic properties along different level tree highlight potential utilizations Duhok- Kurdistan Region Iraq. Specimens six three le...

background & aim: the plants of the greenhouse have been affected by infestation of the pest trialeurodes vaporariorum, called greenhouse whitefly, which markedly reduced production. synthetic insecticides have been widely developed and, their extensive use has brought about disadvantages, like environmental disturbance, pest resistance, lethal effects on non target organisms and toxicity t...

ABSTRACT. Biosorption is a cost effective tool for removing heavy metals from aqueous solutions. In the present study, M. azedarach biomass has been used biosorption of Ni(II) ion solution. The effect pH, contact time, concentration and temperature were separately studied. optimum pH was found to be 6.0. 92% founded, when 25 mg/L initial concentrations at room temperatures in 60 min. It also ob...
