Motivated by the controversy over surface metallicity of Sun, we present a re-analysis solar photospheric oxygen (O) abundance. New atomic models O and Ni are used to perform Non-Local Thermodynamic Equilibrium (NLTE) calculations with 1D hydrostatic (MARCS) 3D hydrodynamical (Stagger Bifrost) models. The Bifrost MHD simulations quantify influence chromosphere. We compare NLTE line profiles new...

a field survey was conducted in wukari, taraba state to assess the diversity and abundance of insect species in selected habitats (residential, open field made up of grassland and an agroecosystem). sampling were done biweekly using light, pitfall and yellow pan traps set in 3 replicates, 30 m apart. insects recovered were wet preserved in 70% ethanol except butterflies and moths. representativ...

non-commercial fish species of shrimp trawls were studied monthly from october 2005 to september 2006 in mahshahr creeks (darvish, doragh, bihad, ghazaleh, ghanam, zangi and patil). the trawl nets had a cod-end mesh size of 24mm. total catch was 6431 individuals weighing 55.5kg, and included 14 species of non-commercial fish species belonging to 14 families. the caught shrimp species were from ...
