This paper presents findings from the geologic mapping of Enugwu-Agidi and its environs. The Early to Middle Paleogene sedimentary succession in Enugwu-Agidi and its environs of Southeastern Nigeria comprises shales of the Imo Formation at the northern portion and the Nanka Formation at the southern portion of the study area which outcrops within the Niger Delta Basin. The aim of the work was to better understand the distribution of lithofacies, identification of various sedimentation processes from their deposits, characteristics of rock units, transport mechanisms and also to establish the Paleo-depositional environments of outcropping units by carrying out detailed geologic mapping of the study area. Based on the field mapping on 12 outcrops and Laboratory analyses which comprised granulometric and pebble morphometry studies on samples collected from the outcrops, the occurrence of 9 lithofacies, which were interpreted to infer deposits of fluvial through marine environments was observed. Paleo-current analysis was also carried out on cross beds of the rocks. The results from granulometric analyses indicate that the sandstones are fine to coarse grained, with mean size that ranges between 0.48 and 2.54. The estimated values for sorting of the grains ranges between 0.86 and 1.14, indicating that the sandstones are moderately to poorly sorted. The probability-log plots show three-segment curve types corresponding to traction, saltation and suspension which may suggest shallow marine environment and two-segment curve types corresponding to traction and saltation which are dominant, relating to deposition in fluvial environment. Studies based on the bivariate and multivariate sieve parameters show a fluvial to shallow marine environment. The three axes: the long (L), the intermediate (I) and the short (S) were measured for 100 pebbles collected from Agwu-Eke and Independent Pebble form indices such as Maximum Projection Sphericity (MPS), Coefficient of flatness (FR %), Elongation ratio (ER) and Oblate-prolate index (OPI) were calculated from these measurements with values of 0.715, 0.102, 52.29 and 0.552 respectively. Based on results from pebble morphometric analysis, the bivariate plots of MPS against OPI and FI against MPS, indicates that the pebbles have been reworked by mainly fluvial processes. The form indices diagram plot indicates that the pebbles are Bladed, Compact Bladed and platy which is diagnostic of river action. The direction of the paleo-current in the study area is NE-SW and based on palaeocurrent patterns classification, the unimodal local current vector pattern indicates fluvial, braided or meandering depositional environment.

These are considerably long in comparison with their lateral dimensions and hence buckle when the axial load approaches a certain critical value known as critical buckling load. In this paper, we present Elzaki transformation means for discussing the Euler’s theory of very long columns with low critical buckling loads to obtain the Euler’s formula for critical or buckling load. It is a powerful mathematical means which is generally applied in different areas of science, engineering and technology for solving ordinary or partial differential equations without finding their general solutions.

This paper focuses on the use of hymns to convey religious messages aimed at making the consumers take the actions communicated by the composers. Many of the hymn consumers seem to pay more attention to their lyrics and rhythms than to the messages and the actions required of them by the composers. Though the hymns can be analyzed using other theories of language, this paper sets to apply John Searle’s Speech Acts theory as the theoretical and analytical frameworks to the analysis of the selected hymns so as to enable a better understanding of the actions communicated by their wordings. Using deliberate sampling, the researchers chose five hymns that exemplify the use of different speech acts in hymns from five popular Christian hymn books available in this part of the world. It was discovered that assertives, commissives, directives, expressives and declaratives all feature in the selected hymns and that the wordings of the hymns fit their communicative intents. It concludes that hymns not only enliven the spirit and gladden the heart by supplying sweet melodies, they communicate messages that embody the actions the composers require of the consumers in the service of their God.

An investigation of the effect of micro denier polyester yarns on the handle of polyester cotton fabrics is reported. These yarns were used in weft with polyester cotton as warp. It has been found that with the exception of shear properties, all the other mechanical properties have been found to be similar. There is no change in handle of fabrics. Drape remains the same for micro denier fabrics and air permeability values are low in comparison with regular yarn fabrics.

Geotechnical as well as geophysical investigation methods were used to provide information for the assessment of the subsurface soil at BOOSTER STATION proposed site at Wuntin Dada near Abubakar Tatari Ali polytechnic gate. Percussion drilling was used to drilled the boreholes to the depths of 4 m and disturbed soil samples were obtained from the boreholes for different laboratory tests at the site. Natural moisture content, specific gravity, Atterberg Limits, Triaxial tests and Permeability Test were conducted. Borehole numbers 1, 2 and 3 have percentages of fines less than 10 %, this indicates that the influence of fine content is negligible on their engineering properties. The grain size analysis of the samples indicates that the total fine content ranges from 1.5 - 20 %, Sand 52.5 – 86.8 %, and Gravel 2.9 – 46.0 %. These values account for the moderate permeability values (1.76 ×10-6 – 3.50×10-6). The OMC was 5.90 - 13.00 % while MDD range was 1.77 - 2.01 Mg/m3. The soils’ cohesion ranges from 8.0 kN/m2 to 75.0 kN/m2 and the angle of internal friction range between 25o to 35o. with these values, the range of computed bearing capacity was 222 – 1132 kN/m2. The results of particle size distribution analysis indicate that very negligible consolidation settlement should be expected. It finally concluded that the material is of high quality with regard to strength and the integrity of the foundation.
