  • Determination and Comparison of CO2 and Air Pollutants Emitted From the
           Exhaust Gas of Selected Electric Generators

    • Authors: Obemeata E. Oriakpono, Uchenna Christian Ohabuike
      Pages: 1 - 18
      Abstract: The study is aimed at providing information on the composition of the exhaust gas and concentration of air pollutants that are generated by different commonly used electricity generators in an average Nigerian household. The generators used for this study were a 0.7 kVA petrol engine, a 2.5 kVA petrol engine and an 8.8 kVA diesel engine. The gases include: CO2, CO, SO2, NO2, NO, O3, Total Volatile Organic Compounds (TVOC), Total Suspended Particles (TSP) and respirable and inhalable particulates (PM2.5 and PM10). The mean concentrations of the air pollutants measured for 0.7, 2.5 and 8.8 kVA generators respectively were as follows: NO had a value of 14.84, 15.8 and 21.84 ppm, NO2 had a value of 6.44, 4.14 and 5.54 ppm, NOx had a value of 21.27, 19.94 and 27.37 ppm, The mean concentration of the air pollutants recorded for 0.7, 2.5 and 8.8 kVA generators includes: 98.0, 60.24 and 0.00 ppm for SO2; 1006.67, 1391.54 and 69.80 ppm for CO; 1000.00, 1266.67 and 1733.34 ppm for CO2; 62.67, 362.34, 80.67 µg/m3 for O3 respectively. The mean value for TSP, PM10 and PM2.5 were 844.57, 1288.57 and 1249.00 µg/m3; 510.80, 763.04 and 760.74 µg/m3; and 333.77, 525.54 and 488.27 µg/m3 for 0.7 kVA, 2.5 kVA and 8.8 kVA generators respectively. Due to the high risk of health hazards and ecological impacts associated with the air pollutants, it is advisable to switch to alternative sources of electricity that are clean and environmentally safe.

  • Development and Validation of an RP-HPLC-FLD Method for the Determination
           of Biogenic Amines after Pre-column Derivatization with a New Pyrazoline
           Based Reagent, 3- Naphthyl-1-(4-trifluoromethyl)-5-(4-carboxy
           phenyl)-2-pyrazoline

    • Authors: Salma Mohamed Al-Kindy, Amal Al Sabahi, Saleh Al-Busafi, Beena Varghese, FakhrEldin Osman Suliman
      First page: 19
      Abstract: Application of 3-Naphthyl-1-(4-trifluoromethyl)-5-(4-carboxy phenyl)-2-pyrazoline (NFCP) as a novel fluorigenic label for the derivatization of biogenic amines (BAs) and separation by liquid chromatography (LC) was investigated. Optimum conditions for the pre-column derivatization and chromatographic separation were investigated. The resulting derivatives are fluorescent at λex/λem: 380/460 nm. For the sake of evaluating the efficacy of the proposed analysis of BAs of different nature, the formation of nine NFCP-BAs derivatives was tested individually. Simultaneous derivatization and separation of four BAs (histamine, tyramine, tryptamine, and phenylethylamine) were achieved under the isocratic elution mode. Furthermore, the derivatives were identified by the characteristic product ion obtained during LC-MS/MS analysis. The viability of the method was established by measuring levels of histamine in fresh and spoiled fish samples. Histamine concentrations were found to be 0.4 µgg-1 and 4.1 µgg-1 in fresh and spoiled tuna fish samples respectively. As a simple, reliable, and sensitive pre-column derivatization method, this work provides for future research to develop a novel HPLC method for the analysis of BAs from food samples such as fish and various other matrices by utilizing the new pyrazoline compound.

  • Archaeo-Geophysical Investigation of Simulated Settlement: Case Study in a
           Part of Basement Complex of Nigeria

    • Authors: Saminu Olatunji, Isaac Onimisi Lawal
      First page: 35
      Abstract: We have used the 2D Vertical Electrical Sounding method and Electrical Resistivity Tomography (ERT) method to map buried artifacts in a simulated settlement, and have shown how the geographical information system could aid future research. Stones, bones, metals, cement bricks, and cement-and-sand mixtures were locally constructed to fit into an African-archaeological setting. Parameters such as the materials’ composition, width, electrical resistivity, height, age, and depth of burial were taken into account before this investigation. The integrated methods employed collected data over the study area along with a pre-calculated dense network of parallel profiles. A total of eight (8) VES points and six (6) ERT profiles were obtained. The analysis and interpretation revealed that the VES yielded poor resolution for small-scale archaeological anomalies and could only be used fractionally for prospection whilst the ERT results were more suitable for delineation due to the high spatial resolution they provided. The field values correlated with other literature values. This research suggests that rapid significant prospection information, of any area under investigation, can easily be obtained from Google Earth time-lapse images and that its results will serve as a thorough reconnaissance in the search of prehistoric activities.

  • Engineering Properties of Umm er Radhuma Limestone, Southeast Ataq, Yemen

    • Authors: Ibrahim A. Al-Akhaly, Abdelmonem M. Habtoor
      First page: 52
      Abstract: Limestone in southeast Ataq, Shabwah governorate in Yemen was studied to assess its engineering properties to ensure their compliance with the minimum construction requirements. This limestone is widely used as building stone in this area. Six different sites were selected for sampling appropriate limestone rock for building stone. 42 representative samples were collected and tested for water content, water absorption, dry density, saturated density, specific gravity, porosity, void ratio, and uniaxial compressive strength to ensure their suitability for use in the production of dimension stone. Tensile strength and elastic modulus were estimated. Their low water absorption, density and porosity values make them suitable for constructing building foundations. Their compressive strength, tensile strength and elastic modulus show their high resistance to crushing and bending effects. Engineering properties data from southeast Ataq limestone were compared with data from various parts of the world. The results showed that southeast Ataq limestone is of good quality and satisfies the ASTM requirements as building stone.

  • Negligence of Geological Investigations Site Leading to Slope Failure
           Incidents: A Case Study From Saih Al Ahmar in Bidbid, Northern Oman

    • Authors: Talal Al-Hosni, Sobhi Nasir
      First page: 63
      Abstract: This paper describes and analyzes a recent slope failure alongside Saih Al Ahmar water storage tank in Bidbid, and identifies the natural and induced causes of the landslide. Our analysis demonstrates that the landslide in Bidbid was the result of several combined factors: slope-forming materials, distribution of geological discontinuities and disturbance by human activities. Moreover, field observations, satellite imagery and geology of the study area indicate that the major factors which caused the landslide are the steep slope excavation along the developed tensional faults, the material in the slide ranging from talus deposits to interlayered peridotite and gabbro, cutting perpendicular to slope talus and removal of the toe of the slope. The slope failure and other stability concerns in the subsurface threatening the structural integrity of water storage infrastructure would not have arisen if the geology of the area had been carefully taken into account before the excavation phase. Landslide hazard assessment in the water tank area and its surrounding is necessary to manage the landslide risk. Proper measures should also be adopted to mitigate the impact and to avoid further failure in the slope already on the verge of movement by rainfall.

  • A Compiled Synoptic table of the Standard Microfacies and Facies Zone
           System of Flügel (2010): A Practical Tool

    • Authors: Frank Mattern
      First page: 74
      Abstract: A synoptic table, compiling the most important information of Flügel’s (2010) [1] complex standard microfacies and facies zone system, is shared with the public. On one page, it contains all standard microfacies (SMF) types, all facies zones (FZ) and which SMFs are associated with which FZs. This table provides the user with a quick and convenient reference/overview, serving students and professionals as an effective teaching/learning and research tool.
