This study utilized Swietenia mahagoni bark–a wood processing industry waste, for the preparation of activated carbon, and then investigated for the removal of methyl orange (MO) dye by the Swietenia mahagoni bark activated carbon (SMBAC). The effect of pH (3–10), adsorbent dose (1–30 g/L), initial MO dye concentration (10–100 mg/L), and contact time (1–240 min) were evaluated...

We study the triangular equilibrium points in framework of Yukawa correction to Newtonian potential circular restricted three-body problem. The effects α and id="M2"> λ on mean-motion primaries existence stability are analyzed, where id="M3"> ∈ − 1 <...

1. The ability of organic and inorganic sulphur to influence the copper and molybdenum metabolism of sheep was compared in a series of three 2 X 2 factorial design experiments. In each experiment, four groups of five to seven hypocupraemic ewes were repleted with a basal diet supplemented with 6 mg Cu/kg and containing S and Mo at one of two concentrations, 1 or 4 g S and 0-5 or 4-5 mg Mo/kg re...

In this paper, we study the solution of difference equation Ω m + 1 = − 7 q 6 / ∏</...

In this study the ability of Acidithiobacillus ferrooxidans, with regard to the biorecovery of heavy metals inshake flask has been investigated. Adaptation experiments with the single metal ions Ni, Co, V, Mo, W anda mixture of the first four metal ions in the medium was developed through serial sub-culturing. Adaptationshowed that A. ferrooxidans could tolerate up to 2.3 g/l ...

ABSTRACT Background and Objective: Parkinson's disease (PD) is an age-related neurodegenerative disorder with massive loss of dopaminergic neurons in the substantia nigra pars compacta. L-Dihydroxyphenylalanine (L-DOPA) substitution is still the gold standard therapy for PD. However, there has been little information available on neuroprotective and regenerative therapies for PD. Due to the neu...
