The high rate of cost overruns of construction projects in Nigeria had led to research into developing strategies and ways to reduce cost overruns in construction project. Based on the material management system implemented in the construction project, this work developed regress...
This study was conducted to ascertain the causes of cement trucks accidents on the three major routes (Routes 1, 2 & 3) connecting Obajana Cement Plant and Rivers State in Nigeria. Data were obtained from questionnaire administered to all truck drivers plying the three design...
The study has been carried out to investigate the influence of manganese concentration and solution pH on the structural and optical properties of electrodeposited Mn-doped ZnSe thin films. The study adopted an experimental research type using lab apparatus to grow and ZnSe/Mn th...
The transition to circular economy has become a sustainable technique to plastic waste management. This makes recycling a key driving machinery for achieving sustainable plastic waste management. However, most of the models that predict the volume of plastic products and its wast...
An investigation has been made to electrodeposit PbO2 anodically by galvanostatic deposition method on Ni substrate from highly alkaline lead acetate bath (0.2 M CH3(COO)2 and 5 M NaOH) containing an anionic surfactant sodium dodecyl sulfate (SDS) for the application of lead-acid...
Solar energy is the most abundant renewable energy source on the earth surface. For many years, research has been done on making use of this source of energy. The current CdTe solar cell technology has good efficiency. However, large scale manufacture of CdTe PV modules are const...

Aim: The aim of this study was to develop a mature biofilm of Enterococcus faecalis in roots using two methods: a Modified Drip Flow Reactor (MDFR) and with Static Method. After this, we eliminated the formed biofilm with a gold nanorods solution and a gold nanorods hydrogel appl...
The corrosion behaviors of SUS 310S in model seawater with different metal cations have been investigated by gravimetric tests and surface analysis. Different corrosion rates were observed in different solutions by the kinds of metal cations, and Zn2+ containing solution showed t...
The potential for indigenous plant fibers to be used as composites in prospective materials and energy applications is growing all the time. SEM, FTIR, XRD, and XRF were used to investigate the potential of new Schizachyrium exiles leaf (SEL) and Raffia Africana otendor (RAOL) sp...
The inhibitive effects of plant leaf, Carica papaya leaves extract (yellow), CPLE (yellow) was studied on mild steel in 1.0 M HCl solution at 30oC using the gravimetric, electrochemical methods and Fourier transform infrared spectroscopy, FT-IR technique. The analysis of spectra...
