The prices of petroleum products in Nigeria have been a source of contention and controversy over the past few years, against the background of low refining capacity, poor public finances and endemic product smuggling resulting in the domestic scarcity of petroleum products. The Nigerian government depends heavily on the importation of petroleum products at very high cost to meet the domestic demand, and it keeps the petroleum products prices below the international oil prices resulting in the implicit subsidization of petroleum products. The huge petroleum subsidy burden of Nigeria puts pressure on funds available to develop other sectors of the economy. The objective of this book is to investigate the impact of petroleum subsidies on real per capita Gross Domestic Product and to propose a framework for an appropriate path for petroleum subsidies in Nigeria thereby seeking to address its challenges for economic efficiency and income distribution. This book would help oil producing countries learn from the Nigerian experience as well as students/academicians studying petroleum related courses.

Dan Garrett has become exactly what he hates-popular. Until recently, he was just another live-action role-playing nerd on the lowest rung of the social ladder. Cue a massive growth spurt and an uncanny skill at taking three-point shots in basketball and voilà...Mr. Popular. It's definitely weird. And the biggest drawback? Going from high school zero to basketball hero cost Dan the secret girl of his dorky dreams. A band geek with an eclectic fashion sense, Zelda Potts's "coolness" stat is about minus forty-two. Dan turning his back on her and the rest of nerd-dom was brutal enough, but when he humiliates her at school, Zelda decides it's time for a little revenge-dork style. Never mind that she used to have a crush on him. Never mind that her plan could backfire big time. It's time to roll the dice...and hope like freakin' hell she doesn't lose her heart in the process.

This book, Influence of Artificial Intelligence on Academic Performance of Benue State University Students assessed the influence of Artificial Intelligence (AI) tools on the academic performance of students at Benue State University, Makurdi. The specific objectives were to evaluate the extent of AI tool usage, examine its impact on academic performance, identify its benefits, and establish the challenges faced in its usage. The Diffusion of Innovation Theory provided the theoretical framework, explaining the adoption patterns of AI tools among students. A survey research design was employed, with data collected from a sample size of 374 students using a structured questionnaire. The findings revealed that AI tools were widely adopted, with 70% of students using them daily, primarily for research and writing. AI significantly improved assignment completion, writing quality, and research efficiency, though it had a lower impact on examination preparation. The study also highlighted challenges such as poor internet access, high subscription costs, and concerns about academic integrity.

Electrochemical technologies have regained their importance worldwide during the past two decades. There are many companies supplying electrochemical method treatment facilities for metal recoveries, treating drink water and various wastewaters. Now days, Electrochemical technologies are compared with other process by means of cost, efficient and compact. The development, design and application of electrochemical technologies for waste treatment have been investigated and some well known processes. Electrochemical processes are promising and alternative methods for treatment of organic wastes and waste water. Mediated electrochemical oxidation (MEO) is one of the sustainable process for waste treatment and has been employed for organic mineralization reactions. In the MEO, a metal ion capable of exhibiting redox behavior is oxidized from lower oxidation state to higher oxidation state by means of electrochemical cell and subsequently used as an oxidant for mineralizing the toxic organic waste into CO2 and water. Many redox mediators such as cerium, silver, cobalt, manganese etc are used in the various electrolyte mediums for this application.
