Self-reported Psychosexual lifestyles of University Students in South-Western Nigeria: Implication for Professional Counselling

Human sexuality is generally described as the sum total of manner through which people experience and articulate their sexual sensation. It encompasses physiological make-up as well as socio-cultural, psychological and spiritual aspects of life.Considerable researches have been conducted on human sexuality among university students but this paper measures twelve psychosexual constructs among six hundred and eight university students (376 males and 232 females) randomly selected from three universities in South-western, Nigeria. Snell (1997) Multidimensional Sexuality Questionnaire (MSQ), consisting of 12 different psychological constructs related to sexual relationships was used to gather data. One research question and one research hypothesis guided the study. Descriptive statistics of frequency count, mean and t-test statistic were employed to analyze the data. The findings indicated that the participants reported higher mean score of 18.37 for psychosexual constructs of sexual esteem and the lowest mean rating of 10.76 for sexual depression,. Further analysis showed that there were no significant differences on sexual esteem and depression of the participants on gender basis. It is recommended that counsellors should broaden sexual recovery psychotherapeutic intervention programmes that will further enhance psychosexual lifestyles of university student

Potensi Mineral Kasiterit Indonesia sebagai Bahan Baku Pembuatan Senyawa Kimia Timah (Tin Chemical)

Indonesia mempunyai potensi mineral kasiterit yang cukup besar dan sampai saat ini belum dimanfaatkan secara maksimal. Kasiterit adalah mineral utama timah dengan rumus SnO2, berbentuk kristal dengan permukaan mengkilap sehingga tampak seperti batu perhiasan. Kasiterit merupakan mineral utama penghasil logam timah. Kasiterit di temukan dalam 2 jenis lapisan yaitu lapisan atau retakan di batuan granit atau batuan disekitarnya dan lapisan sedimen aluvial bersama-sama dengan mineral berat lainnya dalam bentuk pasir. Sifat fisik dan kimia dari kasiterit pada berbagai Negara akan berbeda tergantung ditemukannya kasiterit tersebut. Indonesia memiliki cadangan kasiterit berlimpah yang banyak ditemukan pada dataran dan sepanjang aliran di kepulauan Bangka, Belitung, Singkep dan Kundur. Kasiterit Indonesia mempunyai karakteristik yang cukup kompleks dibandingkan kasiterit di negara sekitanya seperti China, Brazil, Bolivia, Rusia, Peru, Malaysia, Australia, Thailand. Kasiterit Indonesia banyak berasosiasi dengan mineral lainnya diantaranya ilmenit, pasir kwarsa, zirkon, rutil, pirit, kalsit, lantanum dan monasit. Adanya mineral ikutan lainnya dalam kasiterit menjadi permasalahan apabila akan digunakan untuk bahan baku pembuatan senyawa kimia timah.

Pada makalah ini akan dipaparkan secara detail potensi mineral kasiterit Indonesia sebagai bahan baku pembuatan senyawa kimia timah (tin chemical

MECHANICAL STRENGTH DETERMINATION OF CRUSHED STONE AGGREGATE FRACTION FOR ROAD PAVEMENT CONSTRUCTION (CASE STUDY: SELECTED QUARRIES IN WESTERN NIGERIA)

In this research work, the mechanical strength of crushed stone aggregate fractions for road pavement construction in Western Nigeria was assessed. Samples of crushed stone aggregates were collected from nine (9) representative quarries spread across the states in Western Nigeria.The physical and mechanical properties of the aggregates were evaluated. The results were then compared with the specifications in international standards (BS and ASTM Standards). All the aggregate samples met the required limit for Loose Density, Water Absorption, Aggregate Crushing Value (ACV) and Aggregate Impact Value (AIV) tests. Aggregates samples from Samchase, Kopek, CCECC and SaliwaYetidipe quarries have flakiness indices exceeding the permissible limit (29.5%, 25.7%, 27.9% and 34.5% respectively). Hi-Tech and Western quarries samples have elongation indices of 44.5% and 40.3% respectively which are higher than the permissible limit. The two samples that failed Aggregate Abrasion Value test (AAV) are Hi-Tech and Western quarries, having 30.8% and 30.4% respectively. These two aggregates samples have AAV less than 35% which means they are still good for pavement construction only if the appropriate guidelines are followed (since any aggregate with AAV more than 35% is deemed weak for pavement construction). The study concluded that aggregates from Julius Berger quarry have the highest mechanical strength

ANALYSIS OF PARENT – TEENAGER’S COMMUNICATION ON SEX EDUCATION AMONG SELECTED PARENTS IN ABEOKUTA, OGUN STATE

The study examined the impact of parents – teenagers’ communication on sex education. Three research questions were generated for this study. The study utilized a purposive sampling technique to select 246 parents in Abeokuta Metropolis. Results indicated that 59.8% of parents disagreed to discussing sex education with their children until they are fully matured, 76.8% of the parents wait for the right mood of their teenagers before giving them sex education and 63.7% of the parents reported that their teenage child find them boring whenever they want to give them sex education. It was recommended that parents should endeavour to be a friend to their children even before their teen years so as to enable an effective parent – teenagers’ communication.   &nbsp

Integration of magnetic residuals,derivates and located euler deconvolution for structural and geologic mapping of parts of the precambrian gneisses of Ago-Iwoye, Southwestern Nigeria

Ground based magnetic survey conducted between longitude 06O 55I 51IIN –06O 55I 54IIN and latitude 03O 52I 06IIE –03O 52I 4.8IIE (Olabisi Onabanjo University) remarkably revealed a consistent subsurface NW -SE structural azimuth of localized discontinuities within the shallowly buried heterogeneous basement rocks, which at exposed locations are composed of strongly foliated granite gneiss and migmatite-gneiss with veins and veinlets principally orientated in NNW –SSE direction.Magnetic survey of the area was preceded by site inspection to avoid metallic objects interferences. Field procedure in the area involved Cartesian gridding, base station establishment, data acquisition at gridded points, and repeated bihourly diurnal checksat the base station. At the processing stage, diurnal variation effect was aptly removed before subjection to Kriging (gridding). The gridded data was then prepared as input for Forward Fourier Filter Transform (FFT), which upon definition and implementation enabled Butterworth filtering of isolated ringing effects, reduction to the equator (RTE) for geomagnetic correction, and the use of Gaussian and Upward Continuation filtering for regional magnetic intensity trend determination. Removal of the regional magnetic intensity (RMI) from the total magnetic intensity (TMI) resulted in the derivation of the residual anomaly. Enhancement filters adopted for better resolution of the residual magnetic gradient include analytical signal (AS), tilt-angle derivative (TDR), vertical derivative deconvolution (VDD), and the first vertical derivatives (FVD).TMI and RMI values range between 32925nT –33050nT and 32935nT –333050nT respectively, while the residual gradient ranges between 15nT/m and10nT/m; AS ranges between 0.28nT/m and4.1nT/m; and TDR ranges from-1.4nT/m to 1.4nT/m. Source depth calculation estimated from power spectrum analysis and Euler deconvolution ranges between 1m and15m. Composite overlay of magnetic maps revealed jointed and faulted zones within the area; exhibiting a NW-SE principal azimuth of Liberian orogenic impress, which are in consistence with the foliation direction of the jagged foliated bedrock with an estimated maximum overburden of about 15m.The structural significance of this area as a prospective hydro-geological centre, and as an undesirable spot for high-rise building has been accurately evaluated from research findings. Application of integrated geophysical approach, complemented by detailed geological studies may furnish greater information about the subsurface structural architecture.Keywords:Gneisses; Ground Magnetic Surveying;RTE;Structural discontinuities;TDR.1INTRODUCTIONStructuralmapping is an integral part of geologic surveys. It involves measurements, analyses, interpretation and recognition of geometrical features (structures) generated by rock deformations [1]. These structures often serve as fountains of environmental challenges or unparalleled opportunities depending on their modesof occurrences, which in most cases are imminently controlled by the dynamic interplay of differential stress distributions within the earth interior. In line with the principle of uniformitarianism, a broad understanding about Earth’s paleo processes and internal workingsare deductible from the various deformation types for diverse applications. Deductible inferences from brittle deformationsinclude the kinematics of crustal blocks, orientation of principal axes of regional and local stresses, and geometry. Deeper insights indeep seated stresses, regional movements and block motions are obtainable from ductile deformations

Geophysical assessment of subsurface conditions at proposed building sites: implications for foundation failure and building collapse

Building collapse has been a recurrent environmental hazard in Nigeria in the last two decades. This is a corollary of inadequate foundation investigation prior to construction, poor government policies, and general lack of awareness on the importance of geophysical and geotechnical investigations. In this study, geological mapping and detailed geophysical investigation using Electrical Resistivity Imaging (ERI) and Vertical Electrical Sounding (VES) were carried out to understand the suitability of proposed building sites at the main campus of the Olabisi Onabanjo University (OOU), Ago-Iwoye, Nigeria for construction. Both Wenner array and dipole-dipole were used for profiling and Schlumberger for sounding. Four transverses and VES were used in each of the three areas investigated. Our results show that the subsurface of the study areas is underlain by Precambrian basement rock of Nigeria. Rocks in the study area include banded gneiss, porphyroblastic gneiss, biotite-hornblende granite and quartzite schist. The sounding stations across the three areas and 2D resistivity imaging revealed three principal geoelectric layers, the topsoil, the weathered layer and the fractured/fresh basement with varied resistivity values for each layers. At the VES stations, the three geoelectric layers have resistivity values of 62 to 1182 Ωm, 3.2 to 1360Ωm and 87 to 4680 Ωm. On the 2D resistivity imaging profiles, the resistivity of the three layers varies from 2 to 1182 Ωm, 30to 1360 Ωm, and 40 to 2904 Ωm for the topsoil, the weathered basement, and fractured/fresh bedrock. Our work demonstrates that some of the proposed sites are structurally incompetent for engineering or foundation purposes. Excavation of the topsoil and reinforcement are required to sustain the proposed structures

STOCHASTIC PREDICTION OF MONTHLY INFLATION RATES THROUGH KALMAN FILTERING

Inflation measure is an important indicator of the state of an economy and the desire to determine it ahead of “time” cannot be overemphasised. This paper presents a step-by-step algorithm to predict the would-be monthly inflation rate of the Nigerian economy, using Kalman Filtering Predictor (KFP). The ordinary structural model for a time series (structTS) is highlighted to “fairly” compete against our proposed KFP. The structTS is a powerful “competitor”, it is in recommended R package “stats” and used for fitting basic structural models to “univariate” time series. It is quite reliable and fast, and is used as a benchmark in some comparisons of filtering techniques, it is indeed the “predictor” to “beat”, yet our proposed KFP has more to “offer”. The pertinent statistics and pictorial representation of the results obtained, through both techniques, is highlighted for any “incorruptible” judge’s perusal. All of these are contained in the couple of illustrative examples that exhibit the steps involved in the proposed algorithm, using a hypothetical monthly inflation rate and the monthly inflation rates data (January, 2011 to June, 2014) of the Nigerian economy.     &nbsp
