Abstract

A free-piston linear generator (FPLG) is an energy conversion device that can generate electrical energy using different types of fuel. This paper focused on the performance and combustion characteristics of a direct injection spark ignition FPLG fuelled with a mixture of compressed natural gas and carbon dioxide (CNGCO2). An experimental test was conducted under a steady state condition on the engine prototype to study the engine performance at various injection positions (-20, -15, -10, -5, 0 mm) while the ignition velocity and lambda were fixed at 0.6 m/s and 0.6, respectively. Experimental results from the tests reveal that the engine performance and combustion are improved when the injection position is set to -10 mm. Based on this condition, the engine shows a fast combustion reaction when fuelled with the mixture and attains the peak ROHR of 164.83 kJ/s that resulted to the rapid expansion of the gas after combustion. At a high engine speed and operating frequency, the peak power output generated is 1316.1 W as the translator cut the magnetic flux.

Abstract

Accurate future values forecast is the tools Policy makers for tax revenue planning. It’s owed the fact that tax revenue volatility is a valuable measure of uncertainty about the economic environment of a country. This paper applies multivariate time series analysis to the monthly (N Naira) tax revenue data spanning from January 1981 to December 2018 to examine the behavior of tax revenue in Nigeria. To capture the volatility effect in tax revenue data, the paper applies vector autoregression (VAR) and GARCH family models. The study divulges that tax revenue series displays the empirical consistencies such as non-normality non-stationarity, clustering volatility, and serial correlation that validate the application of the GARCH family methods. The study indicates that tax revenue behavior is usually induced by past data about tax revenue. It’s also inferring that previous monthly’s volatility in tax revenue can distress present volatility of tax revenue. In addition, the estimate for asymmetric volatility suggests that positive shocks imply a higher next period conditional variance than negative shocks of the same sign. The main policy implication of these results is that since tax revenue volatility may increase administrative costs and reduce the gains to income revenue, knowledge of tax revenue volatility estimation and forecasting is significant for fiscal policy and tax revenue administrative management.

ABSTRACT

Waste management and sustainability are two fundamental underlying ideas that the construction industry must recognise and execute. Nevertheless, doing so may be difficult and time-consuming. To this end, the aim of this study is to assess sustainable waste management strategies adopted at construction sites in Abuja with the view to enhancing material waste sustainability practises adopted by construction firms on construction sites. The study adopted a quantitative research approach with the use of a structured questionnaire, administered to 155 respondents. Of the 155 questionnaire copies administered, 150 copies were returned and used for data analysis, giving a response rate of 97%. The analysis of the data was carried out with the use of percentage, mean item score (MIS), and factor analysis. The study identified six (6) factors affecting the management of material waste on construction sites, of which financial factors (MIS = 4.08) are the most significant factors. Material costs and energy costs were the most important social sustainability factors (MS = 3.80 and 3.80) respectively. Re-imagine and re-design were identified as the most significant strategies (MS = 4.50). The recycling strategy was identified as the most effective strategy (MS = 4.70). The KMO value is 0.655, and the Bartlett’s test of sphericity is significant (p < 0.05). However, it is, therefore, that the adoption of a sustainable building construction waste management process will minimise, reuse, and recycle construction waste to the greatest extent possible to alleviate the construction waste issue in Abuja and Nigeria at large. The major recommendation from the study was that for waste management to be sustainable in the Nigerian construction sector, an upgrade in either the approach or method of application is required.

ABSTRACT

Introducing modern boiler concepts in the design of thermal power stations is nowadays becoming mandatory, not only from an economic point of view of new investments, but also as a significant and pro-active step towards the reduction of greenhouse gases & dust emissions by the enhancement of efficiency. The increase in the cycle efficiency in modern power station is mainly achieved by increasing the steam parameters.  In addition to elevated steam parameters, other measures such as double reheat design and increased boiler efficiency are the key factors to achieve the desired maximization in heat rates. The aim of this project was to design and fabricate a water-tube boiler using a diesel fired burner (C13H25)9 to generate 80kg of steam per hour. The boiler tank is made of pure mild steel. Mild steel is used to fabricate the water tubes and other parts such as the furnace, smokestack and return chamber that make up the boiler. The heating surface area was increased for sake of efficiency and fast steam generation by reversing the direction of the gas through a second and third parallel tube (three pass). The boiler (which is fired by a diesel burner) generates dry saturated steam at a pressure of 1 bar and temperature of 111.4oC. It can be used for domestic and industrial purposes.

Abstract

People may express themselves on social media sites such as Twitter and Facebook since they are user-friendly and free. Apart from positive aspects of social media, these sites also have disadvantages. Due to laxity to impose limit to express of peoples’ opinions, anyone can make negative and unrealistic comments in abusive or hateful language against anyone with the intent of tarnishing one’s image and social position. As a result, identifying hate content before it spreads to the masses has become a big responsibility for the government and these websites. Due to non-standard differences in spelling and grammar, automatic hate speech identification confronts numerous obstacles. In this paper, we worked with a number of deep learning models such as RNN, CNN, and hybrid of CNN and LSTM with pre-trained Glove word embedding to detect online hate speech and the best performance was found with hybrid CNN-LSTM in all experiments based on accuracy as Twitter 92%, Facebook 90%, and Twitter+Facebook 91%. Our approach can successfully detect hate speech targeted on individuals or group. Therefore, this approach can be implemented to automatically detect and block hate speech across multiple social media platforms. This can also encourage the way towards the development of policies, strategies, and tools to empower and protect vulnerable communities. This may pave the way for the creation of policies, initiatives, and instruments that empower and safeguard vulnerable individuals and groups.

Abstract

The focus of this study is on the effect of public and private sector investments on infrastructural development in Nigeria. The main objective is to empirically examine the links between public and private sector investments and the level of infrastructural development in Nigeria. The study covered the period between 1994 and 2020. The Co-integration test and Error Correction Model  (ECM) were used. The result of the ADF unit root test indicates that all the variables were I(1). The result of the Johansen Co-integration test indicates the existence of a long run equilibrium relationship among the variables. The result of the ECM shows that Private Sector Investments (PINV) and Proceeds from Privatization ( PFP) as proxy for Public Sector Investments, have a positive and significant impact on the Gross Fixed Capital Formation ( GFCF) being proxy for Infrastructural Development. The External Reserves ( ERS) has a positive but insignificant impact on the GFCF. The ECM shows a satisfactory speed of adjustment. The paper recommends amongst others, that the government should provide a conducive environment for establishment and operation of private investments as their contribution to infrastructural development in Nigeria cannot be over emphasized, and also, public and private partnership investments should as well be encouraged.

ABSTRACT

As a security enhancement technique for building, this project was proposed as a way of paving way for integration of one-time password (OTP) technology using microcontroller for security systems. In addition, the proposed project will be a supplement to the challenges of other security authentication methods centered on Bluetooth, radio frequency identification (RFID), biometrics and voice recognition techniques. In other to reduce complexity in design, a microcontroller was introduced to hub the coordination of the system. The two-way verification system which can be coupled with aforementioned security systems, boast of instability to store numeric identity of each user to a building in the electrical erasable programmable read only memory (EEPROM) of the microcontroller. The system prompts a user wanting to gain access to the building through the door to input designated numeric identity (password) stored in its database. Once the inputted designated numeric identity entered matches an identity in the database, then, for the second verification process, a randomly generated OTP which has a programmed validity of three minutes is sent to the user phone via a GSM (global system for mobile communication) module. If either the password or OTP entered doesn’t match, then access is denied and the user will only be relegated to two successful trials with time duration as programmed for retrial, before the system reset for the next user. Electric power to the project was driven from an ac/dc main which was then rectified to power all the dc dependent components used. The low construction cost, user friendliness, flexibility, insured security when compared to other security systems, makes the innovation unique.

ABSTRACT

Because of the enormous changes in climate over time, weather forecasting is quite unreliable these days. As a result, the Meteorological Reporting System is most commonly used to monitor the constantly changing climatic and weather conditions over restricted regions such as homes, industries, agriculture, and so on in real time. Thing Speak is an Internet of Things (IoT) platform that can display weather data and information from anywhere in the world. It also displays on an OLED with two-way microcontroller connection via Wi-Fi hotspots. A weather station can be defined as an instrument or technology that provides us with information on the weather in our immediate surroundings. It can, for example, provide information on the ambient temperature, barometric pressure, humidity, and so on. As a result, this instrument detects temperature, pressure, humidity, light intensity, and rain value. The prototype contains a variety of sensors that can be used to measure all of the aforementioned properties. It can be used to keep track of rooms or location’s temperature and humidity. Other data factors, such as the dew point, can be calculated using temperature and humidity. In addition to the aforementioned features, we can also monitor the location’s light intensity. We’ve also enabled the monitoring of the room’s air pressure. We may also keep track of the amount of rain. The prototype’s brain is the ESP8266-based Wi-Fi module Nodemcu (12E). Temperature and humidity sensor (DHT11), pressure sensor (BMP180), raindrop module, and light dependent resistor are all connected to the NodeMCU (LDR.).

Abstract

Professional ethics are based on a core set of values that enable optimal sustainable development. Despite, professionals in Nigerian construction industry are frequently involved in unethical practices that result in poor project delivery. As a result, studies connected to causes of unethical practices of professionals in Nigerian construction industry were examined. Though, most recent studies have continued to relate unethical practices in the construction industry to Quantity Surveyors. Unfortunately, all-encompassing unethical practices in the construction industry remain an issue for worry among professionals. It is in this light that this study proposed to evaluate the causes of unethical practices of professionals in Nigerian construction industry, with emphasis to determine whether the causes of unethical practices of professionals contributed to the effect on project delivery. Accordingly, a purposive sample of 80 experienced construction professionals involved in selected projects within F.C.T, Abuja was selected, comprising 40 each of Quantity Surveyors, Structural Engineers, Architects and Builders. Data analysis include Mean Item Score (MIS) for ranking the variables and multiple regression to determine whether the causes of unethical practices of professionals contributed to the effect on project delivery. The results of MIS revealed that the top seven causes of unethical practices of construction professionals are professional indiscipline, love for money (greed), favoritism, weak level of supervision, economic downturn, political influence and poor financial control. The results of multiple regression revealed that the causes of unethical practices make a significant contribution (p<0.05) to the prediction of the effects on project delivery. The overall findings revealed that the most significant unethical practices were common among issues of personal behavior, professional indiscipline, profit maximization and economic downturn. It was thus recommended that construction professional/regulatory bodies should ensure effective punishment for unethical activities at different stages of project delivery.

Abstract

In all emerging countries, the originality of Public Private Partnership (PPP) raises new enquiries in governance in allocation of economic, social, and political responsibility among various segments of society in the development of the country; and the adoption of new institutional forms to enhance the efficiency of government action. One of the major factors militating against the successful growth of PPP projects in Nigeria and some part of the world is poor end-user stakeholder management. This paper addresses the challenges by tracing historical and contemporary developments on the need for PPPs; current public protests against PPP initiatives which are perceived as impositions to what the greater public want. There is a paucity of research on end-user stakeholder management in PPP projects within Nigerian context despite significant efforts on research which informs this study. Furthermore, the paper also addresses the challenges facing end-users’ stakeholders by reviewing existing theory and practice positions on project stakeholder management approaches.

Ethics is a comprehensive issue covering all aspects of life. Accounting inludes accounting services and is one of the jobs based on discipline in the world. This profession is associated with one of the issues of people in the society, property and assets of people. Ethical principles or ethics are defined in a set of spiritual values and principles. All of us have such set of values although we don’t know anything about them. If accountants and auditors working in business environment are not dependent upon professional ethics, it has harmful effect for those trusting them. Thus, accounting professional ethics is of great importance for accountants and professional auditors and those involved in auditing and accounting. The present study showed that professional ethics is a necessity for accounting job (accounting and audit). It seems accounting ethics like any accounting product needs accounting and audit. The role and duty of professional accountants to society, capital holders and other people required that they observe all general principles of good morality in all aspects and resort to the professional behaviour regulation to achieve acceptance, credit and social respect as the requirement of activity in each specialized job

ABSTRACT

This study assessed the impact of health and safety deviance normalisation on the labour performance of construction projects in Abuja, Nigeria, with the view of suggesting strategies for eliminating health and safety deviance normalisation. A total of 155 copies of the questionnaire were administered, and 150 copies were returned and used for data analysis, with a response rate of 97%. The analysis of the data was carried out with the use of percentage, mean item score, and Spearman’s rank correlation analysis. The study identified fourteen (14) major causes of health and safety deviance normalization. All fourteen causes had a mean score (MS) ranging between 4.52 and 2.94, with an average mean score of 3.67, which implies the identified causes are important. The result of Spearman’s rank correlation analysis revealed that there exists a positive, fairly strong and significant relationship between the causes of health and safety deviance normalisation and labour performance. At the 5% level of significance (p = 0.01; r = 0.567). The study identified six (6) strategies for eliminating health and safety deviance normalisation by the workers and management (average MIS = 4.09). The study concludes that there is a low level of occupational health and safety policy application and performance in the construction industry. This poor health and safety performance is caused by HS risk normalization promoted by factors such as prioritization of production over safety at construction sites, lack of training of labor, employees’ attitude towards work, inadequate manpower at construction sites, planning issues during the construction process, employee demands, and lack of technical support to labor at the site.

Abstract

Sometimes, raw natural gas from gas reserves is not directly harness able due to high CO2 contents ranging from 25 to 89%. For instance, in Malaysia over 13 Tscf of hydrocarbon gas remains undeveloped in high CO2 fields with the individual field CO2 content ranging from 28% to 87%. Capturing the CO2 is often capital intensive and commercially unviable. This paper underscores part of the outcomes of a study carried out on a facility at Universiti Teknologi PETRONAS, Malaysia. It investigates the effect of high CO2 content-natural gas, as automotive fuel, on exhaust emissions in an internal combustion engine at 180OCA and 300OCA BTDC injection timings. For this experimentation, the natural gas fields were simulated by adding CO2 at 10%, 20%, 30%, and 40% to pure natural gas, and tested in a single-cylinder spark-ignition direct injection (DI) compressed natural gas (CNG) engine. The tests were carried out at a varying engine speed to study the effect of injection timings on emission characteristics of the engine. Experimental results show that generally, the presence of high carbon dioxide content in the natural gas reduces the heating value of the mixture when compared with pure natural gas but however could be enhanced with injection timing of 180OCA BTDC particularly for 20% CO2 proportion in the mixture. There was a reduction in the NOX and CO emissions but an increase in the unburnt hydrocarbons (THC).

Abstract

The aim of this research was to investigate the returns characteristics and the inflation hedging potentials of residential property investment in Abuja between 2012 and 2022. In order to achieve the stated aim, the objectives included: to investigate the average rental and average capital values as well as returns of residential property in the study area from 2012 to 2021; to ascertain the trend of inflation in the study area from 2012 to 2021 and to analyse the inflation-hedging potentials of the investment in the study area. This research work adopted the cross-sectional survey type of design. Primary data used for this study was obtained through questionnaire survey. The data collected was used to calculate the returns. Descriptive statistics was used to analyse the data while the Holding Period Returns formula was employed to determine the returns of the properties. The study revealed that there was a consistent increase in the rate of returns of residential properties in the study area from year to year except a sudden decline in 2019 and 2020. The study also found out that throughout the study period, the actual inflation had been in the double-digit range with the exception of 2013, 2014 and 2015. The study also found out that the returns in the study area indicated a perverse hedge against inflation. This implies that the returns from residential property investment in Phase 2 of the Federal Capital Territory, Abuja, does not have the ability to hedge against inflation. Based on the research findings, it was recommended and concluded that further research be carried out to ascertain the relationship between returns and other components of inflation. The investment information provided in this study has significant implications for both local and foreign investors desiring to invest in the Nigerian property market, with particular reference to residential property market in Abuja.

Abstract

The focus of the study is the examination of the social and economic impact of cooperative societies in Nigeria.  Also to be examined is their impact in our rural communities, especially in the grass root, urban and national development. It has been argued that commercial financial institutions such as banks and insurance companies could play greater roles in the advancement of rural development than the cooperative societies. This is so because of the enormous contribution of these financial houses to the rapid, social and economic development of the people, and urbanization.  Data used in this study covered the period between 2001 and 2020.  Descriptive statistical analytical methods involving frequencies and tables were used to test the hypotheses.  The result shows that as many as these societies may be in form, formation and groups, they have their various challenges, targets, aims and objectives.  The study recommends that government should aid and encourage these organizations to enable them stand and perform effectively since they are all contributive factors in the economic development and growth of Nigeria.

Abstract

This article seeks to broaden the understanding and aggravation of patriarchy as a result of the covid-19 pandemic in sub-Saharan Africa, from a feminist approach. Patriarchy is devastatingly common around the world, and it is more prevalent in Sub-Saharan Africa because of our culture and traditional beliefs, the system of patriarchy encourages the perpetuation of women’s suppression around the world and obsolete practices that suggest that a woman’s role in the society is subordinate to that of a man. This patriarchy grew worse during the pandemic, and it calls for instantaneous interventions to prevent and exterminate patriarchy in sub-Saharan Africa. Patriarchy is a menace to the society because it is a product of gender inequality, and it raises serious public concerns because of its adverse impact on the development of the society and on physical, mental, sexual, and reproductive health. This study employs a feminist theory of black feminism to explain the intricacies of patriarchy, its intensification because of the covid 19 pandemic, and its devastating effect on the society and attainment of sustainable development goals.

Abstract

Sustainable development is an organizing principle for meeting human development goals while also sustaining the ability of natural systems to provide the natural resources and ecosystem services on which the economy and society depend, and that the desired result is a state of society where living conditions and resources are used to continue to meet human needs without undermining the integrity and stability of the natural system. Africa in the past have known to have achieved to some extent the sustainable development until when the global turbulent and covid-19 set in, and continue to pose negative impact on the human, social and economic growth of Africa nation and the world at large. The paper examined the entrepreneurship approaches for combating global turbulent and covid-19 for sustainable development in Africa. Based on the literature review it was discovered that global turbulent and covid-19 have hindered achievement of sustainable development in Africa. The crisis has touched all segments of the population, all sectors of the economy, and all areas of the world. The economic downturn and social disruption caused by the pandemic is Wreaking havoc on lives and devastating livelihoods, sustainable development indices like poverty, economic growth, energy, hunger, health, education, and living slandered  have been negatively affected. 2020 Africa Sustainable Development Report revealed that COVID-19 pushed between 26 and 40 million in Africa (excluding Northern Africa) into extreme poverty and that Africa score 52.9 percent with a gap of  47.1  percent on the achievement of sustainable development goal as at year 2020. The finding further revealed that with entrepreneurship training  problems like poverty, unemployment, economic growth etc will reduce if not eliminated as well as the tragic of any pandemic in future. Based on the findings it is therefore, recommended among that Government of every Nation in Africa should invest in capacity building for entrepreneurial activities to ensure that their knowledge and skills are updated based on industry practice and to have skill to shift from face to face to remote instruction during future crises, Government of Africa nation should provide all the school with the necessary material, tools and machine needed for entrepreneurship education training.

ABSTRACT

An electrically powered egg incubator suitable for hatching fowl (chicken) eggs has been designed and fabricated using the available local materials to achieve efficient performance. The need to embark on this project arose as an effort to contribute in the production of more chicks for poultry farm. The incubator has the hatching capacity of 60 eggs (two crates of eggs). Factors affecting egg incubation include temperature, humidity, ventilation, heat and egg turning rate. These factors are necessary for efficient performance of the incubator. Temperature range of 35.0 – 40.0 oC is suitable, but controlled at 37.5oC by a thermostat. This temperature is close to the bird’s own temperature of 37.0 oC. Humidity was controlled in stages. It was maintained at 60% for the first 18days and raised to 70% for the remaining 3 days. Adequate ventilation is provided when the door of the incubator is opened daily, which also serves as the gateway for the escape of excess carbon (iv) oxide. Filament bulb was used as a source of heat to the incubation chamber.

ABSTRACT

The aim of this study was to empirically evaluate the Effect of Corporate Governance on Financial Performance of Manufacturing Firms in Nigeria (2015 – 2020). The study covered a period of six (6) years. The objectives of this study were to determine the relationship between board independence, board size, board meeting and board gender diversity and financial performance of manufacturing companies in Nigeria. Ten (10) quoted manufacturing companies quoted on the Nigerian Stock Exchange constituted the sample size of this study. The study comprise of a single regression model with a panel of 60 observations in a six-year period, 2015 to 2020. The model has Financial Performance proxied for Return on Asset as the dependent variable and board independence, board size, board meeting and board gender diversity as the independent variables. Panel Least Square (PLS) regression technique was employed in estimating the data and testing the formulated hypotheses. Based on the analysis, the study revealed that there is a significant relationship between board meeting and financial performance of manufacturing companies in Nigeria (proxied for Return on Asset) and that there is no significant relationship between board independence, board size, board gender diversity and financial performance of manufacturing companies in Nigeria (proxied for Return on Asset). In line with the findings, the study recommended that quoted manufacturing companies in Nigeria should consider the increase of the proportion of woman board member (i.e. female representation) in order to improve board behaviour and effectiveness simply because the women on corporate boards tend to be better prepared for the board meetings than men.

Abstract

Nigeria’s external reserves in Millions of US Dollars were modeled using the Box and Jenkins ARIMA approach. ARIMA (1, 1, 1) was fitted, found adequate and was utilized to generate forecasts for January 2020 to December 2023, suggesting an increasing trend. The forecasts are not close to highest reserves recorded in the past. The article observed that for the reserves to attain high levels of the past there must be improved governance, security and infrastructure. The need to extend study to other models was recommended.

Abstract

Water plays a vital role in our day to day life. Most houses, especially in urban areas, uses overhead or underground water tanks for water storage and usage. Overhead and underground water storage tanks are normally opaque, which means the water level in it cannot be observed or monitored visually from the outside, thus the need for water level monitoring systems. This work proposed an RF wireless water level monitoring system that uses RF for communicating the water level data from the transmitter section to the remote receiver section of the system. In the study, two circuits are used, first is the transmitter and second is the receiver. An Ultrasonic sensor is used in the transmitter circuit, which measures the distance of water level from the upper point of the Tank. The distance is measured in centimeters and sent to receiver circuit using RF communication. the result were collected shows that, at a transmission distance of XTR=1m to 10m, and 10 to 20m, (i.e. the distance between the transmitter and the receiver) the readings collected at the receiver is the same with the calibrated readings on the water tank. Which shows that the system performs accurately at a distance of XTR=1m to 20m. When the XTR distance is increased to 30m, there was little or no reception by the receiver, thus, no reading was recorded at XTR=30m. This shows that the system performs at a maximum of XTR=20m, i.e. the range of transmission of the system. Though theoretically, the RF module specification shows that with antenna attached, the transmission range can cover a distance of 100m.
