Filter aids is a salicaceous inert material for separation of liquid and particulate matters. In general filter aids are obtained from mining where diatomaceous earth and perlite are dominantly used as filter aids for industrial applications. The filter aid has important properties of its rigidness, chemically inertness, insoluble, porous, high permeability, and remove finest particles at high rate. Due to its good stability, less impurities, it is on high demand for separation of high purity products of food, beverages and pharmaceutical industries.

This study shows the influence of garnet’s content (Cg) of metamorphic rocks, on the formation of lateritic materials and their geotechnical road parameters according to the standard test methods of the American Society for Testing and Materials (ASTM). Less than Cg (10 percent) involves the formation of fewer nodules, small sizes with a percentage of fines (˂ 80 μm) as high as 61.9 percent. 20 to 25 % of Cg induced the formation of more and larger nodules and low fines (17.0 to 5.9 percent) in lateritic gravel (LG). These values of fines (%fines) are opposed to the optimum dry density values of compaction γdopm (2.000, 2.430 and 2.460) at the modified Proctor optimum and bearing capacity CBR to 95 % (36, 60 and 68 %) of GL. Thus, GL can be used gradually in sub-base for T2, T3, T4 traffic and base for T1, T2 traffic. The Multiple Determination Coefficients (MCD) are 0.966 with R2 = 0.933 for γdopm, 0.743 with R2 = 0.552 for ω (%) and 0.961 with R2 = 0.924 for CBR according to Cg and %fines. Thus, Cg influences the compaction parameters and %fines of lateritic materials derived from garnet metamorphic rocks. The higher Cg of the parent rock, the best of geotechnical properties of GL derived..

A geophysical study of the failed portion of the Ado-Ikere-Ekiti road along Km5 was conducted to investigate the causes of its failure and proffer appropriate solutions to stop the failure. Vertical Electrical Sounding (VES), 2D Electrical Resistivity Tomography (ERT), and Electromagnetic (EM) impact survey using Schlumberger, Dipole-Dipole, and Gradient arrays respectively were employed for the study. VES data were interpreted quantitatively by partial curve matching and computer-assisted forward modeling using the IPI2Win(R) software. The geo-electric parameters obtained from the VES interpretation were used to generate a geo-electric section beneath the traverse. The 2-D subsurface resistivity structures of the failed portion of the road were obtained by processing and interpreting the data obtained from the ERT quantitatively employing the inverse modeling with DIPRO for Windows software. The EM survey electromagnetic fields were transmitted into the ground at varying frequencies to generate an output of frequency effect in percentage which is interpreted as apparent resistivity. The 1D EM geo-section generated by the instrument was used to delineate different formations like clayey/weathered, partly weathered, fractured basement, and fresh basement. The VES soundings produced different geo-electric curve types including the H, K, HA, HK, and KHA types. The geo-electric section revealed four subsurface geo-electric layers including the topsoil, weathered zone, fresh basement, and fractured basement. The topsoil resistivity values ranged from 249-685 ohms-m with a thickness range of 0.6 – 12.8 m. The topsoil is made up of lateritic-sandy soil. The second layer is the weathered zone with resistivity values ranging from 52 – 230 ohms-m and thickness from 0.7- 31.2 m. The third layer is the fresh basement with resistivity values ranging from 532-2866 ohms-m. The fourth layer constitutes the fractured zone of the study area with resistivity values of 269 – 422 ohms-m. The dipole-dipole arrangement revealed a hollow structure that suggested the possibility of a buried stream channel across the study area in an East-West direction. The EM survey confirmed the findings of the electrical resistivity surveys revealing highly weathered zones and the occurrence of deep fractured bedrock even at greater depth. It further confirmed the possibility of the buried river channel in the area. This study showed the possible causes of road failure to be the presence of a thin competent lateritic layer underlain by the thick weathered zone, the presence of fractured zones beneath the weathered zone, and lack of proper drainage at the road embankment. Suggested solutions to this problem include employing stabilization methods (compaction, grouting, or chemical stabilization) for the weathered zones, rock bolting, and grouting for the fractures and putting up drainage systems at the road embankments.

3D laser scanning technology has been applied in mining subsidence monitoring to some extents. Based on the existing observation conditions in the experimental area, the laser point cloud data was collected; Then the methods of point cloud data denoising, registration, filtering and subsidence basin extraction were discussed. Finally, the processing results were analyzed and tested. The results show that: (1) The orientation method has better applicability in mining subsidence monitoring based on TLS, and can avoid the error accumulation caused by the registration method; (2) The error rate of the Irregular Triangulation filtering method with additional constraints on the selection of ground points is 4.22%, which is better than the fitting method; (3) The subsidence basin obtained by TLS has high accuracy, and the mean square error of the difference between TLS and surface subsidence measured by leveling is 3.3 cm.

This study examined the concentration levels of physico-chemical profiles of groundwater quality of communities in Southern Ijaw Local Government Area of Bayelsa State, Nigeria. The seasonal variation of groundwater quality were evaluated. Fifteen (15) communities within the LGA were selected and groundwater from hand-dug well (HDW-15samples) and borehole (BH-15samples) was sourced during the wet season (July) and dry season (March) and analyzed for seasonal variations. The difference in the mean of the parameters investigated during the dry and wet season revealed the difference in concentration level as influenced by the season attributes. The HDW showed a very strong correlation in wet and dry season physicochemical properties as well as no significant difference in the physicochemical properties of groundwater at both seasons. Also, the results of borehole water sample showed a very strong correlation in wet and dry season physic-chemical properties with no significant difference in the physicochemical properties of water at both seasons. There are similarities in various natural and anthropogenic activities influencing the concentrations during both wet and dry seasons. The mean values of parameters such as pH, TDS, TSS, Bicarbonate, Cl, SO34, NO2, Ca, Mg, K and P are within the permissible limit of WHO and NSDWQ during both seasons except TC.

The study conducted evaluated potential of extracts of selected plant species and chemicals on growth of P. hysterophorus. Since the impact of parthenium weed has become to the status of being an extensive economic and social problems of Ethiopian farmers. The experiment identified herbicidal potential of Aregemon mexicana leaf, stem and root extracts and 2, 4-D on seed germination and early seedling growths of parthenium at under field pot condition. Aqueous extracts of 6, 8 and 10 % (w/v), obtained from dry leaves, stem root of Aregemon mexicana plants and 0.3, 0.5 and 0.7 % of 2, 4-D herbicide. The overall germination, shoot and root growth means of A. mexicana extract and 2, 4-D, herbicidal treatments were significant (p<0.0001). Germination hinder by 2, 4-D and A. mexicana stem extracts, which inhibited the germination by (74.4 and 69.3 %) respectively from the control (82.2 %) and the lowest was A. mexicana root extract (54.8 %) in invitro. In the pot experiment the overall growth parameter means of plant extract and herbicidal treatments were significantly lower than the distilled water treated plants. A. mexicana stem resulted 100 % mortality at active growth stage of the parthenium plant, and 2, 4- D also showed best suppressed growth effects. A. mexicana leaf and root gave remarkable seed suppression of (93-94%) at 10 % concentration. Then we conclude that species like A. Mexicana and chemicals like 2, 4-D and are good candidates for future parthenium management. The Small holder farmers adopted mechanical control measures, while, it is most serious is not tackled by these farmers, integrate with other management options such as competitive plants and chemicals may appear to be satisfactory. However further research is required to progress our understanding of the interference mechanisms between parthenium and these species, on how to integrate with other management options and cost effectiveness of the methods.
