ENGINEERS IN SOCIETY: ROLES‚ PROFESSIONALISM AND BEYOND Outline of a talk delivered to engineering students of Universiti Putra Malaysia on Friday‚ 20 February 2004 at Bilik Seminar‚ Faculty of Engineering‚ Universiti Putra Malaysia. BY Ir. Oon Chee Kheng BE(Civil)‚ LLB(Hons)‚ MBA‚ CLP‚ MIEM‚ PEng(M) Advocate and Solicitor 1.0 INTRODUCTION Contrary to the popular perception of life as an engineer‚ this talk will focus on different roles of‚ and played by‚ engineers. Not exactly life

Aldol In this preparative lab‚ an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its

For these reasons‚ Karen should be classified as an independent contractor for the local utility. 2.What factors do you feel help contribute to Karen being an employee? The IRS generally makes this determination. The IRS uses three characteristics to determine the relationship between businesses and workers‚ including the concept of behavioral control that covers facts that show whether the business has a right to direct or control how the work

results in a racemic mixture of benzoin. If both carbonyl groups are reduced‚ the product results in a meso-hydrobenzion or a racemic mixture of hydrobenzion. The goal of the experiment is for the student to reduce benzil and use melting point‚ TLC‚ and IR to determine the stereochemistry of the resulting product. Figure 2: Benzil reduction mechanism: Key experimental details‚ observations and results: The initial reaction solution including the 1.011g of benzil and 10ml of 95% ethanol appeared

growth and retention‚ as well increasing the profit margin for the branch. If I were to dream a little more‚ I would see myself as a branch manager. However‚ prior to that‚ I would have liked to gain some experience in the IR and HR fields‚ maybe training and working as an IR and HR consultant for a short period‚ to gain a better understanding of the different aspects of LabourNet. This would be vital in my path to becoming a Branch manager‚ due to the fact that if I were to lead‚ I would need to

case of theft‚ the exact location of the vehicle can be found by simply sending a message to the GSM modem in the vehicle. The GSM modem then replies us with the location of the vehicle using the data get from the GPS receiver. And also an IR transmitter and an IR receiver is placed in the vehicle door entrance. So‚ whenever an unauthorized person enters the vehicle a message is sent to the owner of the vehicle. In accident identification system a microcontroller is placed to identify the amount

It’s always fascinating to get income tax refund faster but it all depends on the method you prefer to get your IRS refund. Suppose the tax you owe is something less than the sum of the total amount of refundable tax credits claimed and the total amount of withholding paid‚ then you are more likely to avail the benefits of getting federal income tax refund.Some taxpayers prefer to obtain federal tax refund through Earned Income credit which is a real refund of overpayment of tax or through previous

What constitute Tax crimes? A taxpayer committing an act “willfully.” In proving tax fraud the IRS looks for behaviors that determined the taxpayer’s willful intent‚ and conducts that may determine illegal tax evasion such as the existence of a tax deficiency and an affirmation of an attempted evasion. To be prosecuted for tax crime requires a “men rea”‚ which refers to the intent of the individual. IRS needs to prove the evidence surrounding someone’s intent to tax evasion or in evading the legal

cyclohexene product from the cyclohexanol starting component‚ previously learned lab techniques such as extractions and simple distillation were used. The formation of the product was verified by performing a Bromine test as well as an analysis using IR Spectroscopy. A percent yield of 8.33% was obtained. Introduction: In an elimination reaction‚ two substituents are removed from a molecule in either a one or two-step mechanism. There is a removal of a leaving group and a proton to form alkenes

in the experiment. The potassium permanganate test was positive for the presence of a double bond in the product as brown precipitate formed along with the discoloration of the solution. An IR spectroscopy of the product was also performed. Results of the IR absorptions of this experiment were compared to the IR absorptions of standard functional groups as identified by the University of Puget Sound. Three main absorption bands were formed at 3373.46 cmˉˡ‚ 1635.71 cmˉˡ‚ and 1101.39 cmˉˡ. The absorption
