The Lagos lagoon is a depository of last resort for over 70% of the surface runoffs, drainage channels and important rivers flowing from interior Nigeria to the Atlantic Ocean. The surrounding densely populated and industrialized areas often result in the introduction of potential harmful materials into the Lagoon. This work is aimed at providing reference data for the quality assessment of the...

Background: A plethora of data supports HPV-based screening to be the preferred strategy for cervical cancer prevention. The shift a more sensitive first-line test brings need effective triage up discussion. Currently, most algorithms apply cytology as HPV-DNA positive women. This study compared performance 7-type HPV-mRNA cytology. Methods: From 1 January 2019 until 31 December 2021, samples f...

The availability of Te is constrained by the production rate of its main parent compound (copper) and a debate is going on related to the potential supply of Te for very large scale CdTe PV deployment. However, recent investigations point to the existence of Te-rich ores in several places of the world that are likely to allow economic recovery of Te, independently of the production of copper. C...

This work is focused on the application of Cu-containing zeolites as potential environmental sensors for monitoring carbon monoxide. A number commercial with different structural properties (NaX, NaY, MOR, FER, BEA and ZSM-5) were modified using CuSO4, Cu(NO3)2 Cu(OAc)2 solutions copper sources to prepare Cu+-containing zeolites, since Cu+ forms stable complexes CO at room temperature that can ...

I. Three experiments using sixty individually fed, enzootic pneumonia-free Large White pigs on experiment from 9-1 I weeks of age to zoo lb live weight are described. 2. Information was obtained on the effect of different dietary concentrations of aflatoxin B1 on the performance of the pigs, on various biochemical measurements and on the histology of the livers and kidneys. 3. Reduced growth ra...

Tinplate cans were used to study if electro-activated brine solution (EAS) is more corrosive than conventional one by ICP analysis. The results showed different effects of EAS on cans, alone or filled with product. Acidic EAS (pH 2-3) and Redox +900 to +1200 mV highly reacted with the cans. The concentrations of Zn, Fe, and Cu in the solution were 0.028, 28.81, and 0.022 ppm, respectively. No S...

The flotation circuit in Sungun copper plant consists of two column flotation cells as cleaner, having fixed-spargers system. To achieve the expected aims in flotation step, there are serious operational challenges such as: fast choking of the static mixers, boiling problem, burping phenomena and pulp overflow to concentrate lander, maintenance and control problems. An attempt was exerted by im...

The functionalisation of macrocyclic p-tertbutylcalix[4]arenes at the lower rim with hydroxamic acid and proline hydroxamic acid groups gives the calixarenes chelating properties similar to siderophores. The (1)H NMR spectrum of p-tertbutylcalix[4]arene tetrahydroxamic acid shows a broad band at 10.8 ppm in DMSO-d(6) attributed to NHOH protons. Diffuse reflectance spectral analysis of PVC membr...

The parts-per-billion-level nitric oxide (NO) gas sensing capability of a copper-ion-doped polyaniline/tungsten oxide nanocomposite (Cu(2+)/PANI/WO3) film coated on a Rayleigh surface acoustic wave device was investigated. The sensor developed in this study was sensitive to NO gas at room temperature in dry nitrogen. The surface morphology, dopant distribution, and electric properties were char...
