Heavy metal and dyes are among the major pollutants of the environment and the need to constantly monitor the water body is of paramount importance. In recent times, the uses of nanomaterials have attracted the attention of Researchers globally. In this review, the use of nanomaterials as adsorbent was examined with respect to their removal of heavy metals and dyes from wastewater and industrial effluents. The adsorptive performance of these nano-sized materials in terms of capacities and efficiencies, and factors that determine adsorption such as pH, contact time and adsorbent dosage in various studies were reviewed. The models which explain the interaction between the adsorbent and adsorbate (Adsorption isotherms) and the rate of adsorption (Adsorption Kinetics) were also examined. It was found that, on the average, nanomaterials were found to be over 80% efficient as adsorbent of heavy metals and dyes.
This study aimed to select among plants known as host, the one to be used in the production of inoculum from arbuscular mycorrhizal fungi (AMF) in the field. Sorghum bicolor, Plantago lanceolata and Eleusine coracana were cultivated in the plots to assess the density of AMF spores, the affinity between these plants and the main AMF genera, and the frequency of AMF root colonization 4 months after sowing. Sorghum offered 187 spores in 50 g of soil while control plants (Ageratum sp, Bidens pilosa and Eleusine indica) gave only 63 spores. The roots of all plants are colonized but the frequency is higher on Sorghum (55%) which is also associated with a high number of vesicles. Four genera of AMF were isolated and identified: Gigaspora, Dentiscutata, Glomus and Acaulospora. Gigaspora was the most abundant on all crops although all these AMF genus were ubiquitous. Key words: Host plant, spore density, mycorrhizal fungi genus.

In the performance of warm mix asphalt (WMA) two majors concern which are evaluated during this study which are rutting and moisture damage distresses. By using foam bitumen technology in order to produce mixes of WMA two various processes were used. During first process , preparation of samples was done in order to transform mixes of total bitumen into foam bitumen. While in second process, soft and hard bitumenβs were added in mix in which latter was in foaming state. Which resulted same bitumen penetration in the final cured specimens. It was observed that for both foam mixes of WMA the moisture susceptibility and rutting potential increased by reducing mixing and compaction temperature. More ever, it was also concluded that foam mixes of WMA rutting potential during values of Marshall quotient, and results of wheel tracking were significantly more than control hot mix asphalt (HMA). Foam mixes of WMA rutting and moisture susceptibility was found to be decreased when hydrated lime powder was added and observed to be more effective.

Accountability remains a critical matter in almost every area of our lives today. International bodies, professional associations, governments, committees, identify accountability as a major issue. Owing to the fact that boards of directors are given considerable power, it is obvious that they should be accountable for decisions and direction made in their organizations (McDonnell, 2009). Scholars and practitioners agree that authority and accountability are intertwined in corporate law and corporate governance. County governments in Kenya have been in existence for 4Β½ years and most of them face poor performance due to poor corporate governance. The objective of the study was to determine the influence of accountability on the performance in Kenyaβs county governments in Kenya and especially, Machakos County Government. The research used stratified simple random sampling with a target population of 160 respondents made up of 20 county officials in the eight (8) constituencies. The research instruments used for data collection were questionnaires made up of both open-ended and closed-ended items administered to the respondents directly by the researcher. Data collected was analyzed qualitatively and quantitatively using the Statistical Package for Social Sciences (SPSS) software version 20.0. The descriptive statistics used frequency distribution, percentages, means, standard deviations and tables. The study concluded that accountability has a statistical relationship to the performance of County Governments in Kenya. As a result, Machakos County ought to promote increased levels of access to information and most notably execution of duties using power bestowed on county officials.
This research is directed to the use of green corrosion inhibitor (maize husk polar extract) in controlling corrosion on mild steel. Inhibition and adsorption properties of Maize Husk Polar Extract, corrosion inhibition efficiency of mild steel in 1.5M of HCL solution at various exposure time, MHPE concentration was investigated at atmospheric temperature using weight loss test (gravimetric analysis) method with Vacuum rotary evaporator at 790C The result gotten from the vacuum rotary evaporator is 23.99% concentration (mg/100g) from 600.52grams of Maize Husk. Phytochemical analysis revealed the presence of Alkaloids, Flavonoids, Phenolics, Phenolics, Phytates, Saponins, Terpenoids, Anthocyanins, Steroids, and Tannins in the extract. The behavior of MHPE is spontaneous and the physical adsorptions obeys Fourier Transform Infrared Spectroscopy (FTIR), results shows that Maize Husk Polar Extract contains possible compounds with complex structures which are responsible for corrosion inhibition. The results for 384 hours show that the inhibition efficiency increases significantly up to 93.6% for HCL (gravimetric analysis). MHPE appears to be a good inhibitor for corrosion control in HCL; FTIR analysis revealed the amount of detectable functional organic inhibitor in the corrosion product.
This research examined the negative Influence of Social Networking Sites (SNSs) amongst lecturers in University of Jos, Nigeria. The study was guided by twelve objectives. Survey research design was used for the study. The target population was all the (1,640) lecturers in University of Jos that were on ground in 2017/2018 academic session. The research instrument used was questionnaire. Data collected were analyzed using frequency counts, percentages and means. The findings of the investigation revealed among others that: the lecturers made use of SNSs; they used mobile phones to access the SNSs; their preferred access point for using the sites were in their offices and homes in that order; most of the lecturers admitted to be a member of at least one SNS. Their main purposes for using the SNSs were to maintain social contacts with friends/relatives and for academic purposes; their preferred SNSs were Facebook and WhatSapp in that order; they also admitted that the main benefits of SNSs could be expressed in Social Activities, Academic Exercises, Information Dissemination and Business Activities. Majority of the lecturers agreed that the use of SNSs has negative influence on their academic activities because it took time they need to prepare for their lectures and assessment of students (exams scripts, projects), prepare for meetings, research and publication, and community services. It was therefore, recommended among others that: University of Jos Management should organize seminars, conferences and workshops on the benefits of using SNSs for academic activities. However, the negative aspects or the dangers associated with the use of the SNSs and ways to avoid them should also be highlighted. The research therefore, concludes that the use of SNSs by lecturers in University of Jos has negative influence on their academic activities/performance.
This paper discussed the Roles of ICTs in Strengthening Internal Security and Community Policing in Nigeria using Information and Communication Technologies (ICTs) backbone. The need to embrace ICT-enhanced policing in Nigeria becomes imperative because insecurity, robbery, kidnapping, terrorism and insurgency have taken a new dimension and have gone sophisticated as criminal elements have deployed high-tech approach such as mobile technology, internet technology for exploiting and unleashing criminal activities on the society. To reduce this incessant and unpleasant proliferation of modern crime, calls for the fortification of existing policing approach in Nigeria using Information and Communication Technologies. This study is an attempt at strengthening the existing policing approach to be able to meet the insecurity challenges currently being faced and facing the Nigerian society. The study revealed that the incidences of insecurity, terrorism and insurgency can effectively be rendered impotent in Nigeria through the use of ICT. Notably among the proposal for an ICT-enhanced policing is the concept of virtual community policing which explore the availability of mobile devices for easy and effective crime reporting and crime control in Nigeria
This study titled: Curbing the Challenges of Teacher Shortage in Public Primary Schools has largely been shaped by recent events in the country, specifically βUnemploymentβ in Nigeria. The study covered Agbor Education Zone of Delta State. The sample was three hundred and twenty teachers. The instrument for the study were questionnaire and data collected from the Education Zone. The researcher also visited some schools for first hand information of the situation. The paper identified the causes of the shortage of teachers to include retirement of teachers and non-employment for replacement, irregular payment of salaries and fringe benefits, low status of primary school teachers among others. The study revealed that there was shortage of teachers which had implications for both teaching and learning. Finally it recommended that there should be employment of teachers and equal distribution of teachers to all schools in urban and rural area since every primary school has primary class one to primary class six.
This study is conducted to account and evaluate both the over strength and ductility factors on the dual system reinforced concrete structures with regular and irregular pattern in elevation to show their effect on storey shear as well as storey drift. In this study, three 8-storied frame-wall structures (irregular in elevation) and one 8-storied frame-wall structure (regular in elevation) assumed located in a region of high seismicity all with the plan area of 15 x10 meters are analyzed for their responses to lateral loading by applying biaxial analysis in accordance with the Ethiopian seismic code (ES EN 1998:2015) and Ethiopian code for concrete structures (ES EN 1992:2015). The specified 28 day concrete compressive strength of 30 Mpa and the specified yield stress of the steel 420 Mpa were used. The analysis of structures had been carried out by using finite element soft ware ETABS 2016 Ultimate 16.2.1, which is a structural analysis program for static and dynamic analyses of structures. The weight of the systems had been assumed to consist total dead load, DL plus 20% of live load, LL. The results of this study show the importance of the regularity of building structures regarding over strength in their ability to resist horizontal loads caused by earthquakes.
Transparent, Free, fair, and credible elections are core to electoral democracy and provide vital means of empowering citizens to hold their leaders accountable. However, accountability of public officials in Kenya has been undermined by the fact that elections in the country are perennially fraught with irregularities. The announcement of the disputed 2007 presidential election results in Kenya on December 27th, 2007 led to what could be described as the worst political crisis in Kenyan post-colonial history. This study was guided by the following specific objectives; to establish the effect of Biometric Voter Registration (BVR) on the credibility of the Electoral System in Nairobi County, to determine the effect of Electronic Voter Identification System (EVID) on the credibility of the Electoral System in Nairobi County. The study was anchored on Technology Acceptance Theory and employed a descriptive research design. The target population was 2,251,929 registered voters in Nairobi County and 40 Independent Electoral and Boundaries Commission, technical officials. A sample size of 351 respondents was used determined using Fisherβs (2007) formula. Primary data for this study was collected using structured questionnaires. The analysis involved both descriptive statistics and inferential statistics. The inferential results showed a positive correlation of (r=0.773, p=0.000) between biometric voter registration (BVR) and credibility of electoral systems. Results on electronic voter identification (EVID) and credibility of electoral systems showed a positive correlation of (r=0.784, p=0.000). Furthermore there was a significant effect between biometric voter registration (BVR) and credibility of electoral systems (Ξ²=.356, p=0.000), and on electronic voter identification (EVID) and credibility of electoral systems (Ξ²=.380, p=0.000). The study concluded that biometric voter registration (BVR) and electronic voter identification (EVID) in the electoral process is very efficient in reducing or eliminating multiple registrations and multiple voting. The study recommends that there should be adequate and strict protocols for supervision, management and storage of electoral data.
The unsteady MHD viscous incompressible flow of electrically conducting fluid along an infinite vertical porous plate under a strong transverse magnetic field with a rotational system has been studied with the consideration of both Hall and Ion-slip currents. Similarity transformations have been applied to transform the given governing nonlinear coupled PDE into non-dimensional forms of ODE. The Perturbation technique has been used to find the solution of obtaining non-dimensional equations analytically and their graphical representations are plotted by using MatlabR2010a tools. The effects of the pertinent parameters on the velocity, temperature, and concentration distributions have been discussed in detail.
