THE INHIBITIVE EFFECT OF ALANINE ON CORROSION OF ALUMINIUM IN 0.5 M HCL SOLUTION USING THE WEIGHT LOSS TECHNIQUE 

CHAPTER ONE INTRODUCTION

1.1 BACKGROUND OF STUDY

1.1.1 CORROSION

Corrosion is defined as a natural process, which converts refined metal to their more stable oxide. It is the gradual destruction or degradation of materials (usually metals) by chemical reaction with their environment which are most likely inevitable. Corrosion is a natural and costly process of destruction like earthquakes, tornados, floods and vocanic eruptions, with one major difference. Whereas we can be only a silent spectator to the above processes of destruction, corrosion can be prevented or at least be controlled.

Despite different definitions, it can be observed that corrosion is basically the result of interaction between materials and their environment. Up to the 1960’s, the term corrosion was restricted only to the metals and their alloys and it did not incorporate ceramics, polymers, composites and semiconductors in its regime. The term corrosion now encompasses all types of natural and man – made materials including biomaterials and nanomaterials, and it is not confined to metals and alloys alone. The scope of corrosion is consistent with the revolutionary changes in materials development witnessed in recent years.

1.1.1.2 CORROSION AND ITS MECHANISM

In nature, metals are not found in free state due to their reactivity. Metals are generally in high energy state because some energy is added during their manufacturing process from the ores. Low energy – state ores are more stable than the high energy – state metals. As a result of this uphill thermodynamic struggle, the metals have a strong driving force to release energy and go back to their original form. Hence the metals revert to their parent state or ore under a suitable corrosive environment. The electrochemical process involved in corrosion by nature is opposite to the extractive metallurgy involved in manufacturing of the metals.

According to electrochemistry, the corrosion reaction can be considered as taking place by two simultaneous reactions:

The oxidation of a metal at an anode (a corroded end releasing electrons) and the reduction of a substance at a cathode (a protected end receiving electrons). In order for the reaction to occur, the following conditions must exist:

1.      Two areas on the structure must differ in electrical potential.

2.      Those areas called anodes and cathodes must be electrically interconnected.

3.      Those areas must be exposed to a common electrolyte.

1.0     Introduction

Data mining is the process of sorting through large data sets to identify patterns and establish relationships to solve problems through data analysis. Data mining tools allow enterprises to predict future trends. It is an interdisciplinary subfield of computer science and statistics with an overall goal to extract information (with intelligent methods) from a data set and transform the information into a comprehensible structure for further use. Clifton, Christopher (2010); Hastie, Trevor et al., (2009).  Data mining is the analysis step of the “knowledge discovery in databases” process, or KDD.Fayyad, Usama et al., (1996). Aside from the raw analysis step, it also involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating. The difference between data analysis and data mining is that data analysis is to summarize the history such as analyzing the effectiveness of a marketing campaign, in contrast, data mining focuses on using specific machine learning and statistical models to predict the future and discover the patterns among data.Olson, D. L. (2007).  

The term “data mining” is in fact a misnomer, because the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction (mining) of data itself.Han, Jiawei; Kamber, Micheline (2001). It also is a buzzword and is frequently applied to any form of large-scale data or information processing (collection, extraction, warehousing, analysis, and statistics) as well as any application of computer decision support system, including artificial intelligence (e.g., machine learning) and business intelligence. The book Data mining: Practical machine learning tools and techniques with Java (which covers mostly machine learning material) was originally to be named just Practical machine learning, and the term data mining was only added for marketing reasons. Bouckaert, Remco R. et al., (2010). Often the more general terms (large scale) data analysis and analytics – or, when referring to actual methods, artificial intelligence and machine learning – are more appropriate.

CHAPTER ONE

INTRODUCTION

1.1       Background of study

A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). (The Authoritative, 2000). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source. A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static inverters do not use moving parts in the conversion process. (Power Inverter, 2014)

A solar inverter, or PV inverter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS) –component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection. (Solar Inverter, 2014).

The solar inverter is a critical component in a solar energy system. It performs the conversion of the variable DC output of the Photovoltaic (PV) module(s) into a clean sinusoidal 50 or 60 Hz AC current that is then applied directly to the commercial electrical grid or to a local, off-grid electrical network. A solar cell (also called photovoltaiccell) is the smallest solid-state device that converts the energy of sunlight directly into electricity through the photovoltaic effect. A Photovoltaic (PV) module is an assembly of cells in series or parallel to enlarge or increase voltage and/or current. A Panel is an assembly of modules on a structure. An Array is an assembly of panels at a site. Typically, communications capability is included so users can monitor the inverter and report on power and operating conditions, provide firmware updates and control the inverter grid connection.At the heart of the inverter is a real-time microcontroller.

The controller executes the very precise algorithms required to invert the DC voltage generated by the solar module into AC. This controller is programmed to perform the control loops necessary for all the power management functions necessary including DC/DC and DC/AC. The controller also maximizes the power output from the PV through complex algorithms called maximum power point tracking (MPPT). The PV maximum output power is dependent on the operating conditions and varies from moment to moment due to temperature, shading, soilage, cloud cover, and time of day so adjusting for this maximum power point is a continuous process.

Definition of Motivation
The word motivation is derived from the Latin word “movere€ which means to move. Today, the term motivation means move. Motivation ahs been defined by many scholars in various ways, but meaning the same thing. Motivation is a driving force that initiate and direct behaviour.  Motivation is a reason for action that which gives purpose and direction to behaviour.
Olatunle (2003) described motivation as all those inner striving conditions described as wishes, desires, drive etc. it is an inner state that activate or moves and direct behaviour towards goals. “human motives are based on needs whether consciously or unconsciously felt”.
Debra and James (1997), “Motivation is the process of arousing and satisfying goal directed behaviour.
Burton and Tharkar (2005) defined motivation as those course that force people to behave in different ways.
Cole (2002) desire motivation as “ the process in which people choose between alternatives forms of behaviour in order to achieve personal goals.
James and Lindner (1995) defined motivation as an inner force that derives individuals to accomplish personal and organizational goals.
Higgins (1995) say motivation is an internal derives that satisfy and unsatisfied needs. Greenborg (2009), defined motivation as a process of arousing directing and maintaining behaviour towards a goal. Robin and Delengu (1995), says motivation is the willingness that exert high level of effects, ability to satisfy some individual needs.
Halljreid et al (1982), look at motivation as that which causes channels and sustains individuals behaviour. A factor which ginger an individual to apply more of his effort and talent to the services of his employer. Appleby (1990), refers motivation to the way urges, aspirations derives and need of human being direct or control or explain their behaviour. It may be described as the way for a particular pattern of behaviour.
The Oxford Dictionary (4th Edition) defines motivation as “the act or course for action that urges a person to set a certain way”.
Having looked at the definitions of motivation by various scholars, motivation is simply spurning the work force of greater productivity, as it encompasses all those and sustain human  behaviour. Managers, by definition are required to work with and through people, so they must gain at least focus, that will motivate people they are to manage. People are complex and are uniquely different. Managers who want to be successful need to learn, to understand the concept of human motivation and should be able to use that understanding to achieve high standard of subordinate work performance.

DESIGN AND CONSTRUCTION OF A MODERN NAIL GASKET MACHINE. A RESEARCH PROJECT MATERIAL ON MECHANICAL ENGINEERING

ABSTRACT

The design and fabrication of a reciprocating nail gasket is a new innovation in technology. The one in existence is manually operated. In which a punch that is adjacent to a die is mounted to the handle  which  is attached to the shaft. A helical spring that is incorporated to the shaft of the punch, helps the handle return to its initial position, which makes the machines tedious and stressful to operate. When the handle is pulled down from its initial position, the punch passes through the die that is placed  vertically adjacent to the punch thereby blanking out the felt materials. The number of the gasket produced is proportional to the strength of the operator. But in our design, we incorporated  a geared motor which does the cutting in a reciprocating form, while the operator  just drags the felt material to the die where it is cut. The efficiency  of the machine is well above 75%, it can produce 216 felts per minutes . sprockets and chains are used to transfer power  instead of belts in other to effect good phases relationship. The material used for the punch is stainless steel rod. The machine is statically and dynamically balanced to curb noise and vibration. One and half (11/2) inch angle iron was used in fabricating the skeletal frame.
Appropriate materials were subsequently selected and fabricated to required size. The machine was then  to perform efficiently thus satisfying the objective for which it was designed.

ABSTRACT

          Parameters on which clear prints depends were comprehensively investigated.  The study revealed that clear print depends on the impressed pressure, the working temperature and the silver print paper.   Also studied were the manners of dependence of these parameters on prints impressed on sheets of varied thickness.  The result of this investigations were utilized in the design and construction of a operational hot (manual) printing machine.

CHAPTER ONE

INTRODUCTION

    1. IDENTIFICATION OF NEED

In recent years Nigeria lays strong emphasis on mass literacy and indigenous technology.  Printed matters are indispensable material in mass literacy campaign. The trend towards indigenous technology imposes a severe clamp down on imported engineering including printing machinery.  Thus, the situation is such that makes the acquisition of printing machinery from outside our own borders extremely difficult.
To lessen the economic strain on the mass literacy campaign, the production of local printing machinery I s apparently imperative.  It is this fact that rendered initiative to the conception and realization of this low cost but efficient printing machine based entirely on local technology and resources.
This machine is very useful in the printing of many items like paperbacks, cards, leatherbacks etc.  Its design is expected to motivate and advance the design and construction of other machines destined for similar purposes and based on indigenous technology and resources.
1.2       PURPOSE OF THE PROJECT
            Civilization and complexity of modern society has brought a number of social problems to be traced.
The use of textbooks, printed materials such as success cards and posters has now become imperative for the overall dissemination of heart felt  feelings and messages to friends both near and far.
Unfortunately, the prevailing economic pr oblem in the country (Nigeria) have sky rocketed the prices of these items.  Renders for example now rely solely on the libraries for up dating their knowledge.
It becomes clear then, the need to equip the libraries to met up with the challenges of their services.
Apart from refurbishing damaged books libraries are expected to render services such as printing of cards, printing and binding of students write ups like thesis, project etc.
All this needs formed the basis for the construction of this machine because these functions cannot be performed without a printing machine.

CONSTRUCTION OF TWO FACE GAS BURNER. A RESEARCH PROJECT MATERIAL ON MECHANICAL ENGINEERING

CHAPTER ONE

INTRODUCTION

The construction of a two-face gas burner as a project topic that we embark upon become necessary as a way of way of putting into application the engineering and technological knowledge acquired so far. It is a starting point of actualizing a functional technology in the country. Irrespective of the fact that there are several breads of gas burners in the market, especially the ones imported, we deemed it necessary to work further on it as a way of modifying the brand with cast not left out in such modification.

1.2     LITERATURE REVIEW
          The development of simple gas burner started in the eighteen countries when people began to use coal gas for burning. The application was fast put into practice by William Mulock who designed the simple gas cooker to be used in his office, home and workplace
The first experimental gas cooker was made and in use in 1850. The improvement of this has multiplied greatly and is up to date widely used in homes, restaurants and large catering establishments. The different types of gas cookers available in the in the market are based on skills and techniques of the designer or producer.
Based on the nature of energy supply, some gas cookers are made up of combustion devices of an electric heating element. The well-constructed ones are properly adapted and form an integral combustion of which of which they generate and utilize heat. It is often quite different to draw a line where heat generation stops and where heat utilization starts in a fuel forced cooker. That is the fuel fired cooker being on the pack in the market these days.
The releasing of heart starts with mixture of air and fuel gas in the nozzle and combustion of the mixture to release heart takes place at the burner.

INTRODUCTION
Candle molding machine is universally used for molding candlestick, which supplement light during darkness.  Since man is endowed with the gift of sight and to make use of it in darkness a light source is required and the attempt made to aid man in his shortcoming leads to the production of a candle-molding machine had undergone series of modification in order to meet the standard and requirements.  The recorded first candle-molding machine was made of iron bars, welded flat to four by four stands and covered with jute materials.  Due to the integration of certain properties this was replaced with hard wood, but hard wood could not stand the test of time due to wear and lack of other desirable properties.
Eventually, light mild steel iron pipes of different diametre were used with raypia but all this could not get to the major requirement of the machine
To ease production and to save cost.  Most of the technical inventions were concentrated to arrest technological and human constraints as well aesthetic sensibility.  However, the introduction of Aluminum pipe (Duraluminum) ie alloy of aluminum, copper, magnesium and manganese brought a lot of designs and reliability as well as ease of manufacture.  More so, the jute materials was replaced with Tarpautin or twine.  The first candle moulding machine can now be found in museum for technological research in Paris, city of France and Manchester laboratory in England.

          Based on this, we fabricated a portable candle moulding machine which is influenced by a number of factors ranging from cost of finished product, low scale production, ease of manufacture more do the product which must correspond to specifications in the design process of this sort, the mechanical properties of the materials used were taken into consideration such as weld ability, strength, portability and impact resistance according to functional requirement.
