Identification of major noise donors, a sure way to abating noise

A Study was conducted to ascertain the specific noise emitted by presumed noisy environments. This was achieved by direct measurement of the noise with the use of an integrated sound level meter in which a built-in frequency filter or weighting network is incorporated. Ten (10) environments were selected in Ilorin and Akure towns in Nigeria, in which sixty (60) readings were taken at intervals of 30 seconds for 30minutes separately at each location. This amounted to an overall reading of six hundred (600) readings. The results show that the Lawn Mower emits noise with the highest Equivalent sound level

A new species of Henneguya (Myxosporida, Protozoa) from West African catfish, Clarias lazera Val., with a review of the genus Henneguya Thelohan, 1892

A new species of myxosporida, Henneguya clariae, is described from the gills of Claria’s Iazera caught from various waters in Nigeria. Pathogenic effects in the destruction of the components of the branchial system are about 25% of Clarias lazera. A review of the genera Henneguya myxobilatus, and Neohenneguya is made and these were synonymised, with some reservations in the case of to Henneguya. A checklist of the genus Henneguya is given

Space technology as a centrepiece for addressing Nigeria's domestic challenges and strengthening its foreign relations

Nigeria’s regional hegemony has recently been weakened, mainly due to domestic issues. The state’s over-reliance on crude oil resources and insecurity have impacted its influence in Africa. Over the past two decades, there has been a search for a sustainable means of addressing national issues, especially to augment alternative sources of revenue and tackle security concerns. This would stabilise the domestic environment and, by extension, impact Nigeria’s foreign policy. Essentially, Nigeria needs an enduring source of power to revive and sustain its influence in Africa and enhance its foreign relations. In light of this, this research examines the use of space technology in Nigeria. It considers the existing Nigerian space capabilities—its expertise, satellites, ongoing space infrastructural projects, and space relations—to be central to strengthening the state’s foreign policy. Thus, the thesis does this in three dimensions: it examines the use of space capabilities to stabilise the Nigerian domestic environment; Nigeria’s leverage of its space capabilities for acquiring power in Africa through the control of security, production, knowledge, and finance structures; and Nigeria’s space partnerships and the impact on its space diplomacy. Nigeria’s partnerships are mainly with China Great Wall Industry Corporation (CGWIC) and Surrey Satellite Technology Limited (SSTL) in the UK. China is a space power, while SSTL is a prominent satellite manufacturer. This study examines the impact of these partnerships, particularly the Asian state’s influence on Nigeria’s spacepower. The theoretical framework is informed by the theories of Neoclassical realism, spacepower, and IPE structural power. The research adopts a qualitative method that combines document analysis and semi-structured interviews. On this basis, the research seeks to make at least three fundamental contributions. The first is a theoretical contribution to the further development of the spacepower concept, specifically how Nigeria’s use of space capabilities in its foreign policy contributes to the theory. The second is the thesis’ application of structural power theory to Nigeria’s control of structures and strengthening of its regional power and space diplomacy through space capabilities. Accordingly, the study proposes space as a new power structure. The third is the contribution of space to the domestic environment and its potential role as an enabler of Nigeria’s material power capabilities. Generally taking into account Nigeria’s foreign policy, which is mainly Afrocentric, and its space relations, the study makes suggestions on how to improve the state’s engagement going forward and the importance of having experienced space diplomats who have the interests of the state at heart. This will ensure that Nigeria maintains consistency in its foreign policy and achieves tangible results in its interactions with global space players

Equipment for application of postemergence directed sprays for weed control in narrow-row no-tillage soybeans

A field study was conducted in 1983 at The University of Tennessee Milan Experiment Station to assess the potential for using tractor-mounted postemergence directed spraying equipment for weed control in no-tillage soybeans (Glycine max) planted with 20-inch row spacing in wheat (Triticum aestivum) stubble. Six commercial or experimental directed sprayers either designed exclusively for or adapted to use in 20-inch rows were used to apply a tank mix of linuron and 2,4-DB in 12-inch soybeans. Crop injury due to both mechanical damage and chemical contact were subjectively assessed for each system. Sprayers producing the most injury (up to 40 percent) had some misaligned machine assemblies or had limited capability for adjustment of row protection shielding. Two shielded sprayers resulted in crop injury ratings of 10 percent or less. A single herbicide application with any of the sprayers gave good control (80 to 88 percent) of cocklebur (Xanthium pensylvanicum) with no significant differences among applicators. Control of large crabgrass (Digitaria sanguinalis) was poor (40 per cent) with all sprayers primarily because the grass was severely drought stressed at the time of application. Drought conditions during the growing season resulted in abnormally low yields. No significant differences in yields were shown among the treatments. However, yields in sprayed plots tended to be greater than those from untreated plots

The Influence of University Personnel Upon Students\u27 Spirituality at Selected Adventist Universities in West Africa

Problem and Purpose. The Seventh-day Adventist Church has a deep concern for youth and young adults\u27 spirituality. Hence the church established institutions of higher learning with the aim of restoring in youth and young adults the image of God in which they were created. There are programs and activities in these institutions to accomplish the aim, but there is still concern among church leaders and parents that young people will abandon their faith and exit the church. This study explored the influence of interactions between students and university personnel in selected Adventist universities in West Africa that, apart from programs and activities, might facilitate the development of biblical spirituality. Method. A quantitative research design was used to survey students of the two selected Adventist universities in West Africa, Babcock University (Nigeria) and Valley View University (Ghana). A sample of about 800 students was randomly chosen from the two universities; 787 students gave responses good enough for analysis. The instrument used for the study was adapted from the Christian Spirituality Participation Profile (CSPP) and the Multidimensional Measurement of Religiousness/Spirituality (MMRS). The participants indicated the frequency of their interaction with university personnel and the perceived impact of the interaction on student spirituality. The participants also indicated their level of spirituality. Descriptive analysis was used to determine the frequency of interaction, the perceived impact of interaction on student spirituality, and the level of student spirituality. One-Way ANOVA was used to determine the influence of some demographic factors on frequency of interaction and perceived impact of interaction on student spirituality. Canonical correlation was used to determine the interrelationships between interaction and student spirituality on the one hand, and the perceived impact of interaction and student spirituality on the other. Results. The level of interaction with students was higher with faculty than other university personnel. The perceived impact of interaction on student spirituality was higher with faculty than other university personnel. Student spirituality was high. Students who were older in age, at a higher level of study, and who were Adventist had more interaction with university personnel. Student spirituality correlated with interaction with university personnel and perceived impact of interaction on student spirituality. Students who were older in age, in a higher level of study, and Adventist had higher levels of spirituality. Conclusion. Intentional interaction with students by university personnel from the time of enrollment will help students to develop biblical spirituality. The interaction has to be positive and with authentic concern for students\u27 holistic growth. Universities should be loving communities where students can freely discuss spiritual matters. The religious backgrounds of students should not determine the interaction between university personnel and students

Jesus’ Personal Identity Disclosure: An Exegetical Study of Mark 2:1-12

Many people are concerned about the identity of Jesus. It is easy for many to accept his humanity. When it comes to his authority, there are sceptics with different justification. This controversy over the identity of Jesus was also evident he was on earth. Jesus used different approaches to reveal his personal identity. Jesus used the healing of the paralytic to settle the identity matter as found in Mark 2:1-13. This exegetical study therefore considered the pericope (Mark 2:1-13) bringing out the central theme of the passage which has to do with Jesus and self-identity.

Investigation of the Properties of Locally Available Dolomite for Refractory Applications

A study to investigate the properties of the locally available dolomite for refractory applications has been carried out. Dolomite samples from four dolomite mining locations at Ikpeshi, Ugya, Osara and Kwakuti in Nigeria were used for this investigation. The internationally accepted methods for testing refractories were adopted and their properties compare favourably with most of those of standard dolomite currently in use in Europe, Asia and United Kingdom. These results make the Nigerian dolomite suitable for use as a basic refractory material especially in the machine tools and steel making industry

Effect of Post-Dehulling Treatments on Anti-Nutritional and Functional Properties of Cowpea (Vigna Unguiculata) Flour

Recently, cowpea (Vigna unguiculata) has been cited for imparting specific positive health potentiating responses when properly positioned in the diet. However, inherent anti-nutritional factors in cowpea have long been recognized as concerns and require appropriate processing conditions to ameliorate adverse effects. The study focuses on effect of post-dehulling treatments on anti-nutritional and functional properties of cowpea flour. Three genotypes of cowpea (IT99K-573-2-1, IT96D-610, and IT07K-292-10) were dehulled. Dehulled cowpeas were boiled, roasted or autoclaved and prepared into flour. Raw (dehulled) cowpea genotype served as control. Anti-nutritional and functional properties of the products were determined using standard procedures. Antinutrient concentration of cowpeas differed significantly (p≤0.05) among genotypes. Tannin, phytate and oxalate concentration ranged from 31.15 to 121.80g/kg, 22.31 to 48.04 g/kg and 0.01 to 0.026g/kg respectively. Coloured beans (IT96D-610), had significantly lower anti-nutritional content than those of white beans (IT99K-573-2-1 and IT07K-292-10). All heat treatments significantly reduced the levels of  investigated anti-nutrients compared to their respective control. Water absorption capacity and oil absorption capacity were found in the range of  2.12–3.07 mL/g and 1.37-1.73 mL/g, respectively. Swelling power, starch solubility, loose bulk density and packed bulk density varied between 10.79 to 18.42g/g, 0.16 to 1.52g/g, 0.64 to 0.73g/mL and 0.84 to 0.94 g/mL respectively. Colour parameters (L*, a*, b*, hab, C*) showed significant  variations among the genotypes. The combined varietal and processing variation induced significant modification in the inherent anti-nutrients and functional properties of dehulled cowpea as attested by the highly significant (p≤0.05) correlations observed. Processing of cowpea seeds in these forms presents an opportunity for extending their use beyond the dehulled seeds in food system. Keywords: Cowpea, dehulling, treatment, nutrients, functionalit

Evaluation of Vertical Electrical Sounding Method for Groundwater Development in Basement Complex Terrain of West-Central Nigeria

This research evaluated the Vertical Electrical Sounding (VES) method of groundwater development in the Basement Complex terrain of West Central Nigeria. It was aimed at verifying the reliability of VES in differentiating lithologies, predicting the depth to basement and probably, aquifer in groundwater development. In doing this, the Schlumberger electrode configuration was employed in the surveys while partial curve matching and computer iteration techniques were used to interpret the curves obtained. In all, seventy three VES were carried out and fourteen boreholes constructed. Comparison was made between the predicted depth to basement from VES and the actual depth from the drilling log. A linear relationship between the actual depth and that predicted by VES was established with coefficient of determination of 0.94 confirming the reliability of the VES method. None of the boreholes drilled was abortive.KEYWORDS: Groundwater, aquifer, geoelectric measurement, fractured zon

A longitudinal mixed-method investigation of sexual development amongst a school-aged sample of adolescents in Ibadan, Oyo state, Nigeria.

Background: Around 1.2 billion people, or 1 in 6 of the world’s population, are adolescents aged 10 to 19. Evidence has shown that in most countries of the world children are attaining puberty and biological maturity at an earlier age. This trend may perhaps be due to improved nutrition though other factors may also be at play. In every population, adolescents are amongst the most sexually active of groups and may become involved in regular unhealthy and risky sexual practices that further threaten future reproductive health. STIs (including HIV) and unintended pregnancy among adolescents remain both a risk and public health burden, in spite of long-term efforts at prevention. Aim: This study aims to critically investigate the understanding and experience of sexual development of a school-aged sample of adolescents in Ibadan, Oyo State, Nigeria by means of a longitudinal mixed-methods approach. Methods: An adapted version of the WHO ‘Asking young people about sexual and reproductive behaviours’ survey was administered at baseline and 6 months (n=121). Hierarchical Cluster Analysis of baseline results was used in order to determine a sampling matrix for the qualitative phase of this study. The emergent clusters differed on the basis of whether participants were home or peer oriented in their outlook. Semistructured interviews (n=10) were undertaken with a mixture of peer-oriented and home-oriented young people. Result/findings: Statistically significant differences were determined between baseline and 6 months in terms of whether members of the sample had ‘ever had a boy/girlfriend’ (χ² = 20.407, P ≤ 0.000), ‘ever had sex before’ (χ² = 5.493, P ≤ 0.019), as well as changes in attitudinal orientations towards sex before marriage (U = 2268.00, P≤0.017). Thematic analysis of qualitative data revealed a complex interplay of factors mediating adolescent sexual choices including informational, family, peer, cultural and social structural factors. Conclusion: This study provides some evidence in support of the role of social structures in determining adolescent sexual choices: adolescent development is a reality, but not one that can be understood solely in terms of agency or culture. It can, therefore, be argued that society and government have a role to play in supporting young people in 4 | P a g e making responsible sexual choices. Improving adolescent sexual and reproductive health remains a public health priority both locally, nationally and internationally
