Nitrosamine Accumulation, Processing Variables, and Indigenous Plant Inhibitors in Nigerian Traditionally Processed Meats
Abstract: N-nitrosamines are classified as probable or possible human carcinogens by the International Agency for Research on Cancer. Carcinogenic N-nitrosamines — principally N-nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA) — are formed in abundance during the preparation of widely consumed Nigerian traditional processed meats including suya, kilishi, and balangu. This original investigation combined a six geopolitical zone of Nigerian market survey with laboratory-controlled model system experiments, effects of processing parameters on N-Nitrosamine formation …

Lower Genital Tract Infections in Pregnant Women: Epidemiology and Risk Factors Associated in Dakar, Senegal
Abstract: Vaginal infections are responsible for many problems in women of childbearing age and significantly influence pregnancy outcomes. This study sought to ascertain the prevalence of lower genital tract infections and the risk factors associated with them in pregnant women under observation at the Nabil Choucair Health Centre in Dakar, Senegal. This nine-month cross-sectional study, which involved women between 34 and 38 weeks gestation (WG), was carried out from July 2020 …

First Insights into Whole Genome Sequencing of the Mycobacterium tuberculosis Complex: Molecular Diversity and Drug Susceptibility Patterns in Senegal
Abstract: Background: We conducted a bibliographic analysis of the Mycobacterium tuberculosis complex (MTBC) in sub-Saharan Africa, which included the analysis of 8,139 genomic sequences from 34 of the 49 sub-Saharan African countries. Notably, only one complete sequence from Senegal was identified, which had been generated in the United States. Our primary objective was to utilize whole genome sequencing (WGS) to detect resistance in anti-tuberculous strains of the MTBC in Senegal. This …

Enhanced Oil Recovery through the Application of Nanoparticles with Irvingia Gabonensis in Flooding Process in the Reservoir
Abstract: This experimental investigation is aimed at establishing the ability of nanofluids formula from a mixture of nanoparticles and oil extracted from Irvingia gabonensis (bush mango) in enhancing recovery from oil reservoir. The laboratory study involved the use of core flooding unit, crude oil, brine, nano-particles and Irvingia gabonensis. In this study, nanofluids formulated from nanoparticles of aluminum oxide (Al 2 O 3 ) and zinc oxide (ZnO) respectively were used …

SYNTHESIS OF LOCAL OIL-BASED MUD FOR NIGER DELTA WELLS USING ELAEIS GUINEENSIS
Abstract: Abstract Edible oil is produced from palm kernel (Elaeis Guineensis), a widespread tropical fruit that has a specific gravity of approximately 0.9°C, a flash point of 242°C, a flash point of 251°C, and a pour point of 22°C. This experiment was conducted by replacing liquid paraffin oil, a known component of conventional oil-based mud, with palm kernel oil (PKO) in the synthesis of a new oil-based mud from local materials. …

A Portable Induction Hardening System with New Dynamic Response based Characterization of Hardened Samples
Abstract: In this paper we have first discussed about the requirement of a portable induction hardening system which can be easily tailored for variable job-work applications. Such a system is first developed in the laboratory and successfully utilised for hardening steel pins made of various alloys. Later, it is shown that the dynamic response of such a system can be used for hardness estimation as these are sensitive towards the change …

Monitoring the Structural Health of RC Beam Lap Splices using Wave Propagation and PZT Sensors
Abstract: This paper describes the use of piezoelectric sensors in a wave propagation-based Structural Health Monitoring (SHM) method to identify lap splices in steel reinforcing bars. Straight and lapped steel bars with lap lengths of 10° and 20° were used for the experiments. Lead Zirconate Titanate (PZT) transducers were employed, one of which served as an actuator to produce stress waves and the other as a sensor to record the signals …

Wireless Intelligent Accurate Bridge Deck Crack Inspection and Mapping
Abstract: One of the important tasks for building maintenance is building deck crack inspection. However, the inspection result in human analysis is less accurate in nature. So, a crack inspection system that uses a camera-equipped mobile robot to collect images on the building deck has been proposed. In this method, the Laplacian of Gaussian (LoG) algorithm is used to detect cracks and a global crack map is obtained through camera calibration …
