    Get PDF
    A multi-sensor optical shape measurement system (SMS) based on the fringe projection method and temporal phase unwrapping has recently been commercialised as a result of its easy implementation, computer control using a spatial light modulator, and fast full-field measurement. The main advantage of a multi-sensor SMS is the ability to make measurements for 360° coverage without the requirement for mounting the measured component on translation and/or rotation stages. However, for greater acceptance in industry, issues relating to a user-friendly calibration of the multi-sensor SMS in an industrial environment for presentation of the measured data in a single coordinate system need to be addressed. The calibration of multi-sensor SMSs typically requires a calibration artefact, which consequently leads to significant user input for the processing of calibration data, in order to obtain the respective sensor's optimal imaging geometry parameters. The imaging geometry parameters provide a mapping from the acquired shape data to real world Cartesian coordinates. However, the process of obtaining optimal sensor imaging geometry parameters (which involves a nonlinear numerical optimization process known as bundle adjustment), requires labelling regions within each point cloud as belonging to known features of the calibration artefact. This thesis describes an automated calibration procedure which ensures that calibration data is processed through automated feature detection of the calibration artefact, artefact pose estimation, automated control point selection, and finally bundle adjustment itself.

    High profile corporate collapses and fraud with which accountants are said to have been associated with has given rise to the questioning of the integrity of the professional accountants. This systemic failure has brought into focus issues of long standing debate with respect to how to curb this act and regain the confidence of the public in the professional accountants and the professional accountancy bodies at large. The study examined the impact of code of ethics on the conduct of professional accountants in Nigeria. Regression Analysis, Correlation Technique and Ttest were employed in analyzing the data collected. The results revealed that the fundamental principles of ethics have a significant impact on the positive conduct of professional accountants. It further revealed that there is no difference in the various opinions of stakeholders with respect to the impact of the code of ethics. It is therefore recommended that early stage teaching of ethics in all schools and continuous improvements taking into consideration changes in time, based on the current trend should be encouraged. There should also be a program in place to effectively monitor the adherence level of accountant

    Ameloblastoma: Current Etiopathological Concepts and Management

    Get PDF
    Ameloblastoma is a benign odontogenic tumor of epithelial origin. It is locally aggressive with unlimited growth capacity and has a high potential for malignant transformation as well as metastasis. Ameloblastoma has no established preventive measures although majority of patients are between ages 30 and 60 years. Molecular and genetic factors that promote oncogenic transformation of odontogenic epithelium to ameloblastoma are strongly linked to dysregulation of multiple genes associated with mitogen-activated protein kinase, sonic hedgehog, and WNT/β-catenin signaling pathways. Treatment of ameloblastoma is focused on surgical resection with a wide margin of normal tissue because of its high propensity for locoregional invasion; but this is often associated with significant patient morbidity. The relatively high recurrence rate of ameloblastoma is influenced by the type of molecular etiological factors, the management approach, and how early the patient presents for treatment. It is expected that further elucidation of molecular factors that orchestrate pathogenesis and recurrence of ameloblastoma will lead to new diagnostic markers and targeted drug therapies for ameloblastoma. © 2017 John Wiley & Sons A/S.

    The high cost of plant protein inclusion in human and animal diets and the need to find alternative sources to traditional protein sources is on the increase. Winged bean (Psophocarpus tetragonolobus), a tropical underutilized legume was therefore analysed for its nutritional and anti-nutritional contents using different processing techniques. Two kilograms (2kg) of winged bean seeds were purchased, and samples were divided into different parts and subjected to two different processing techniques; baking at 250oC and boiling at 100oC for 20 minutes. An unprocessed portion was also separated as control. Samples from each processing technique and control were subjected to analysis for nutritional and anti-nutritional factors using standard laboratory methods. The crude protein content of winged beans from baking, boiling and control was 17.93%, 19.59 and 12.55% respectively. Crude fat was 11.25%, 9.25% and 10.40% in that order. The highest anti-nutritional factor of 2788.45 mg/100g and 3254.57 mg/100g was recorded for processed and unprocessed tannin composition also. Oxalate values reduced by 22% and 19.74%, while, phytate content reduced by 20% and 18.12% for the processed boiled and baked after baking and boiling respectively. Nutritive and anti-nutritive compositions of the processed and unprocessed winged beans were significantly different at p>0.05.  Processing is therefore a viable means of increasing the nutritive value and in turn reducing the anti-nutritive values of winged beans

    Get PDF
    The COVID-19 pandemic is anticipated to continue to the year 2022 and could lead to several business failures if entrepreneurs do not respond adequately. Thus, the purpose of this study is to introduce a framework that captures the impacts and potential responses to the ongoing pandemic. To do that, we conducted telephone interviews with ten entrepreneurs who operate enterprises within Nigeria. Data collected for analysis were transcribed, chronologically arranged, coded, and thematically analyzed using NVivo. Our findings revealed that, during the pandemic, businesses experienced limited opening hours, a decline in their clients' patronage, lower turnover, and employee demotivation. In response, business owners should consider re-strategizing their business activities, maintaining connections with clients, and exploiting available support measures. Our findings have profound theoretical and practical implications. For entrepreneurs and policymakers, they offer insights into the form of challenges confronting businesses during a pandemic. It also provides response activities that entrepreneurs could adopt to mitigate the impact of an epidemic on their enterprises’ performance. For the field of entrepreneurship, it advances the need to integrate public health (health-related issues) into entrepreneurship study and consider its multiple levels of influence on the performance of businesses

    Get PDF
    This study examined the view of stakeholders as to whether or not Fair Value Measurement (IFRS 13) increased disclosure will lead to more meaningful investment decisions. The study adopted the Survey research design involving the collection of data from auditors of the “Big 4” and accounting academics in selected private universities in Nigeria. Primary data were obtained through the administration of copies of survey questionnaire to respondents. Two hypotheses were formulated and tested using Peason Product Moment Correlation and Independent Sample T-test at a significant level of 5%. Findings from the study revealed an association between IFRS 13 increased disclosure requirement and investment decisions. The result also revealed differences in the standpoint of accounting academics and auditors regarding the impact IFRS 13 increased disclosure have on investing decisions. The study recommended that the Financial Reporting Council of Nigeria should ensure that all companies in Nigeria fully adopt IFRS 13 in the preparation and presentation of their financial statements

    E-GOVERNANCE AND PUBLIC SECTOR FINANCIAL DISCLOSURES: ANALYSIS OF GOVERNMENT AGENCIES IN NIGERIA

    Get PDF
    One of the core responsibilities of any government to its citizens is financial accountability and transparency. This is to re-assure the stakeholders that the government is people oriented and enables the stakeholders to hold the government in power accountable to its electoral promises. In Nigeria therefore, financial dealings of the government and its parastatals has been shrouded in secrecy. Unlike in the private sector, where financial disclosures are made known to owners of the business (Shareholders) at the Annual General Meetings (AGM), the public sector in Nigeria has not emulated this. Therefore, e-governance platform is imperative for government to reach a wider audience in term of impact and delivery. The question therefore is that, is Nigerian government both at the federal, state and local government engaging this platform to disclose their financial transactions? And rarely when they do, are they making full disclosures of the financial activities? A government that discloses its financial activities would enable stakeholders analyzes its performance and asks questions on the financial prudency of the state and this would prevent corruption and theft of peoples’ collective/common wealth. This study analyzed the contents of various government parastatals website to determine whether these agencies make financial disclosure and the extent to which those disclosures are made. In addition, the study also considered whether stakeholders are allowed to contribute or suggest alternative(s) in form of feedback to the government. It is therefore recommended that the audited financial report/statement which is a stewardship report showing how the common wealth allocated has been utilized. As such, the Financial Reporting Council and other government regulatory bodies should endeavor to mandate Ministries to place on their various websites a copy of the audited account of the Ministries and perhaps a copy of such report sent to appropriate quarters to ensure complianc
