Evaluation of endocrine disruptors in the environment of Eket Metropolis in Nigeria: an insight into public health and risk assessment

Abstract: The adverse effect of some environmental contaminants on the endocrine system was investigated using the Risk Analysis Framework. The aim was to ascertain the level of EDCs in fish species and potable water. The research employed ecological examination approach. The samples from the environmental media with serious threat and links to humans and animals exposed to endocrine disruptors were water and fish. Twelve boreholes water samples were disproportionately and purposefully collected, while another twelve water samples were collected from Qua Iboe River one kilometer stretched forth. Also, six species of fresh fish including - Atlantic croaker ( Micropogonias undulates ), Catfish ( Clarias gariepinus ), African red snapper ( Lutjanus agennes ), Tilapia ( Oreochromis niloticus ), Yellowtail ( Seriola lalandi ), and Great barracuda ( Sphyraena barracuda ) were used. Both the water and fish samples were screened for endocrine disrupting substances with gas chromatography linking mass spectroscopy. The analysis (results) detected 8% phenol dichloro-4-nitro-, 1, 3, 5-Triazine, and 3% Triazine 2-chloro-4-, 6-bis-methylthio, octadecenamide in borehole water. Butyl ethyl, hexyl phthalate, indolizine 6%, 4-methyl phenyl, cyclohexane, 3-dione 27%, 2-allylamine methylene 5, 5-hydroxyphenyl 8%, and menazon 17% were discovered in all the species of fish. Phthalate, butyl undecyl esters, 2-ethyl hexyl was 4%, and 7% of isohexyl propyl in Qua Iboe River. The results call for the attention of the regulatory body to put in place measures that will stem the impending disaster this may create in the reproductive capacity of the exposed population.

First report of Cucumber mosaic virus infecting Ocimum gratissimum (L.) in Calabar, Cross River State, Nigeria

Abstract: Leaf samples of Ocimum gratissimum (L.) exhibiting vein banding, mosaic and chlorotic spots were collected randomly from the field. The symptomatic samples reacted positively to specific CMV antibody in antigen coated plate enzyme linked immunosorbent assay and to confirm the presence of CMV, RT-PCR was performed using CMV-specific primers that amplify a 519 bp region from the viral coat protein gene. The expected amplicon shared homology of 97.06% with a Nigerian isolate MH178110. Phylogenetic tree constructed revealed the isolate in close association with CMV strains belonging to subgroup II. This is the first molecular evidence of CMV in O. gratissimum in Nigeria and adds to the list of natural host for the virus.

Capitalization of Interest Costs

Abstract: Capitalization of interest, from the financial stand-point, refers to the cost associated with the borrowing of funds, or obtaining a loan in order to finance the acquisition of certain fixed assets. The focal point of this paper is an examination of the nature of the costs of fixed assets that can be capitalized Consequently, discussions revolve around the meaning of capitalization of interest or borrowing costs; steps that are involved in the computation of capitalization of interest costs; the arguments in favour and against interest costs capitalization. Technical difficulties or problems that confront an organization‘s policy on capitalization of interest costs such as the identification of the amount of financing costs that should be capitalized are also discussed. The paper concludes that there are finely balanced arguments in favour and against capitalisation. Furthermore, enterprises should be allowed to decide whether or not to capitalize their borrowing costs on fixed assets that take a substantial period of time to bring into service; and the requirements that are applicable to those enterprises that do not capitalize borrowing costs are aimed at ensuring that a consistent capitalization policy is adopted within the enterprise. Again, through disclosure the impact of capitalization on the results and financial position of the enterprise are understood; and that there is comparability between enterprises capitalizing interest costs

INVESTIGATION OF THE ATOMIC CHARGES, ELECTRON DENSITY, ELECTRONEGATIVITY, AND BOND LENGTH OF BeH2 WITH GGA + U FUNCTIONAL

Abstract: In this paper, Bader atomic charge for BeH2 was calculated. Pauling electronegativity for Be, bond length and hydrogen ionic radius for BeH2 were also determined. Electron density difference GGA + U and GGA-PBE was plotted. It was observed that GGA + U does not notably charge the charge state of the ions. As expected, the charge difference between the two hydrogen ions was 0.05e (approximately).
