Difficulties Faced for writing in University Classes

In this entry, I will state some of the difficulties that I have faced for writing in university classes. Writing comes in many forms, such as formal, informal, essay and many others. Thus, for each category, there is a different approach to present our writing. I will further discuss on the difficulties I had faced for formal and essay writing.

Firstly, I will touch on formal writing, in the form writing a proposal. During the last semester break, I have been busy writing proposals for the annual industrial visit for the course. I have faced the difficulty of trying to make the proposal looks professional, yet interesting and convincing. Though the proposal may not be very long, it took me days to complete it. Firstly, I have to read through the history and some other pertaining information of the company. In addition, I have to keep amending my drafts before coming up with the final copy. In short, writing a proposal may not seem as easy as it is. It requires a lot of amendment and reading up of the company's detail.

As for essay writing, it is rather different from those that we have done in high school. Essay writing in university requires research regarding the topic. On top on that, we have to quote some of the facts and include them in our essay. Citation is a totally new thing to me. Hence, for the start, I have faced difficulty in the format for citing from the different sources. In addition, there are many minor details which we have to be precise. As such, it has taken me quite some time before i got use to the format for citation.

In conclusion, writing in university is much different for that of high school. Nevertheless, if one puts in the effort to learn and to find out, these difficulties will not hinder us in our writing.

Identifying three common grammar mistakes

In this entry, we are required to state three common grammar mistakes that we make frequently. In the following paragraphs, I will be covering on 'independent and dependent clauses', ' subject/verb agreement' and 'preposition'.

An independent clause is a group of words that contains a subject and verb, expressing a complete thought. An independent clause is a sentence. Whereas, a dependent clause is a group of words that contains a subject and verb, but does not express a complete thought. A dependent clause cannot be a sentence. There are two types of words which we can use as connectors at the beginning of an independent clause: coordinating conjunctions and independent marker words. There are seven coordinating conjunctions which we can use, namely; and ,but,for,or,nor,so,and yet. An independent marker word is a connecting word used at the beginning of an inde pendent clause. Below are some of the examples using coordinating conjunctions and independent marker words as connectors.

1)Coordinating conjunctions: Peter went to McDonald to study,but he could not concentrate because of the noise.
2)Independent marker word: Peter went to McDonald to study; however,he could not concentrate because of the noise.

The second mistake to be discussed is the subject/verb agreement. The subject and verb should match in number, meaning that if the subject is plural, the verb should be a plural as well, and vice verse. Below are some of the examples in subject/verb agreement mistakes.

Mistakes:
1)Students is required to buy that textbook.
2)Below is some of the examples.
3) One of the boxes are open.
Corrections:
1)Students are required to buy that textbook.
2)Below are some of the examples.
3)One of the boxes is open.

Some of the common prepositions used are: on,at,in...etc. In this paragraph I will only be covering on the common mistakes made when using the following three prepositions; 'on','at' and 'in'. The word 'on' is used with days, 'at' is used with the time of the day, and 'in' is used with other parts of the day, months, years or seasons. Some examples of the common mistakes are further elaborated below.
Mistakes:
1) I will see you at Monday.
2) The movie starts on 6pm.
3) The book was published at 2008.
Corrections:
1) I will see you on Monday.
2) The movie starts at 6pm.
3) The book was published in 2008.

These are the few common grammar mistakes that I have encountered. Throughout my course of EG1471, I have a better understanding and awareness of such mistakes.

Summary for roundtable discussion

This week, we had our roundtable discussion. The topics were given to us before the recess week so that we can research for more information regarding the topics during the one week break. The topics covered in the roundtable discussion are as followed; biofuels, green chemistry, micro-chip implantation, and carbon dioxide capture and storage. This discussion enabled me to have a better understanding on the various technologies.

The purpose of green chemistry is to improve on the technology such that it helps to reduce and prevent pollution. The proposition states that the world is currently facing global warming as a result of the rapid industrialisation. In order to increase the gross profit of the country, many organisations have neglected the environment. This results in the increase of carbon dioxide capacity in the atmosphere, causing the melting of ice caps which leads to flooding in many low lying areas. Hence, countries should work on the green chemistry such as using renewable resources, energy efficient technology, and the introduction of safer chemicals and products. However, the opposition argued that green chemistry should not be implemented in all countries. Instead, it should only be implemented in the developing countries only. As for the developed countries, most of their technologies have already been fully established. As such, it will be very costly for them to switch totally to a new technology. Whereas for the developing countries, they can easily adapt to this new technology, and at the same time, educate their workforce on the fundamentals of green chemistry. I think that the opposition does not have strong evidences to oppose green chemistry. The opposition only argued that the green chemistry should only be introduced to developing countries. In addition, he did not illustrate on how the developing countries will be able to support this technology, given their financial status.

The next group presented on the implantation of micro-chips into every human. These micro-chips will be useful in a sense that they speed up the process of retrieving one's medical history and other personal data. This is extremely helpful in times of emergency where every second counts. With any delay, the patient's life is at stake. Therefore, with these micro-chips, the medical history of the patients is just a scan away. However, the opposition argued that the micro-chips may not seem as useful as they are. These micro-chips implanted into our body may travel to other parts of our body or organs, which may be a disaster. In addition, in this world where hackers are not uncommon, one's security and privacy will be very vulnerable. As such, this technology is not feasible as there are too many loop-holes. I think that this discussion is rather clear and the opposition has provided sufficient arguments as to why this technology is not advisable.

The last topic that was discussed was about carbon capture and storage. The idea of carbon capture is to reduce the amount of carbon dioxide in the atmosphere, will contributed to global warming. The process of how this technology works was discussed. Furthermore, the proposition discussed that there is an increasing concern regarding the environmental issues, and many countries are emphasising on being environmental friendly. Hence, the adoption of this technology can also help the organisation to gain world wide recognition. On the other hand, the opposition argued that this technology is both risky and costly. Leakage may occur should there be any miscalculation, which will introduce more harm. In addition, he argued that in order to gain recognition, there are many others ways, and there is no such need to spend a huge sum just to gain recognition. Although the jokes in the discussion may capture the attention of the audiences, I think that it is inappropriate in a formal discussion. In addition, the opposition does not have a clear argument as to why he opposed the technology. Instead, he countered the proposition by saying that he is not convincing ith their explanations.

This roundtable discussion enables me to better understand the various technologies. Unfortunately, due to the time limit, only a few of us manage to have our doubts clarified. In addition, we are also unable to wrap up and conclude discussion. I think that we should go through the discussion as a whole, so that we can learn from the mistakes made in each discussion.

Summary of 2 articles.

In my preparation for roundtable discussion and the writing assignment 2, I have done various researches on the topic regarding biofuels. Having done so, I have come across various interesting articles. In this entry, I will summarise two of my favourite articles about the technology of biofuels.

The first article, titled "Food vs fuel?" discusses about the anti-biofuels controversy. This article states about the various reasons as to why certain group of people or organisation oppose to the idea of biofuel. In the later part, the author analyse to what extent is the use of biofuel harmful. Firstly, the poor term biofuel as "crime against humanity". The production of biofuels drives millions of the poor population into starvation. As the demand for biofuel crops increases, the prices of this food crops skyrocket. As a result the prices of food become less affordable for the poor. Secondly, tropical rainforests are being destroyed to make way for biofuels crop plantations. Statistic has shown that "farming is responsible for 14 per cent of greenhouse gas emissions". The use of chemical fertilisers has introduced a huge amount of nitrogen into the soil, and nitrous oxide into the air. However, in the later part, the author argues that biofuel is an advantage when it is being utilise in a controlled manner. Biofuels are clean, green, renewable and sustainable. It should be produced in small-scale projects focusing on local production for local use.

The second article titled "Making biofuel from Pond Scum" was my favourite article. The idea of producing biofuel from algae was totally new to me. The fact that algae can produce 100 times more biodiesel per hectare than either canola or soy was an amazing fact to me. The author added that the production of oil from soy or canola generally requires a three to five-month growing season. However, algae are so prolific that they can double or triple overnight, and over half a batch can be harvested for oil production every day. In addition, the growth of algae does not require fertile soil. It only requires flat land, carbon dioxide and sunlight. Moreover, the growing troughs in which the algae grow under are sealed with clear plastic lids that allow in plenty of sunlight, but keep the water the plants are floating in from evaporating. As such, it is even possible to grow algae in the desert. Last but not least, the cost of biofuel is only about $70 a barrel, which is highly affordable and competitive to oil that are produced from fossil fuels.

After looking up for all these information, I have a better understanding for biofuel. These articles also provide me with more facts for the discussion in the roundtable and also in my writing assignment.

Summary Of Lecture Held On 30th January

During this short two hours, there were three presentations made by three different professors. The three presentations were all related to climate changes. The following paragraphs will summarise what each presenter had covered on, and also some of the pointers that interest me.

The first presentation was by Professor Andrew Palmer. His presentation was about the various ways in which we can adopt to reduce the emission of carbon dioxide. There is a huge increase in carbon dioxide emission after the 'Industrial Revolution'. From then on, researchers have been sourcing for ways to reduce emission. There are several ways to reduce emission, such as using alternative energy source, fuel efficiency and also the capturing and storage of carbon dioxide to reduce dumping to the atmosphere. Solar energy can serve as an alternative for the usage of coal. People are also encouraged to utilise public transports so as to reduce the use of cars. In addition, carbon dioxide can also be captured and stored in the oceans, as liquid carbon dioxide is denser than the sea water. Lastly, Professor Palmer concluded that the reduction of carbon dioxide is global, but not a local problem. This explains why it requires the cooperation of all the countries in this world in order to tackle the problem.

The next presentation was by Assistant Professor Benjamin. Technology is a double edged sword. It provides us with greater convenience and comfort. However, it may also be harmful if we misuse it, such as the effect of terrorism. There are several reasons as to why the use of renewable power was not successful. Firstly, it was due to market barriers, where consumers have to pay for the license to install solar panels. Secondly, there was no incentive to encourage the use of renewable energy. He also added that the use of electric vehicles was a failure due to economic and technical challenges. The batteries are much heavier and expensive as compared to gasoline. He ended his presentation by stating that no technology is self sustaining, and technology is part of social system.

Lastly, Professor Bala presented on global warming. There is a sharp increase in global temperature in the recent years as a result of the growing population which leads to the increase in consumption. The increase in greenhouse gases traps the heat within the atmosphere. The Arctic temperature is increasing 2 times faster as compared to 20 years back. In addition, the sea level is increasing due to the melting of glaciers. These are evidences of global warming. He ended his presentation with the consequences of global warming, which greatly contributed to the increase in floods, droughts, and also the extinction of various flora and fauna.

The lecture has imparted some interesting facts to me. I was startled by the rate at which carbon dioxide is dumped (200 tonnes C/sec and increasing). The concept of storing liquid carbon dioxide in a membrane so as to prevent it from diffusing into the ocean and hence causing it to be acidic was totally new to me. Lastly, I was also glad that they explained the reasons as to why the various steps to reduce emission were not successful.

An Inconvenient Truth- Global Warming

Former United States Vice President Al Gore, had came up with this video so as to increase the public's awareness of global warming. Many may have known about the existence of global warming. However, only a handful of them are aware about the seriousness and harmful effect of the global warming. As such, many do not see the need to deal with this arising problem or to reduce the emission of greenhouse gases into the atmosphere.

The main factor that is contributing to the increasing problem of global warming is globalisation. Globalisation has resulted in a vast increase in the number of factories, cars and also apartments for its growing population. In order to accommodate to the increase in number of such infrastructures, rapid deforestation has resulted. As such, not only does it increase the amount of carbon dioxide contributed to the atmosphere, but there are also fewer trees to replenish the air. Hence, more heat trapping gases such as the carbon dioxide are being trapped in the atmosphere. The effect of globalisation on global warming has been shown statistically that the 10 hottest years have occurred in the last 14 years.

In fact the main contributors to the greenhouse gases are the developed countries, but not those developing countries that are less educated. In order for the developed countries to remain competitive in the market, the government of these countries urge their people to increase productivity. As such, deforestation in such countries is not uncommon, to provide spaces for its growing infrastructures, and more carbon dioxide are also emitted from the increase in machinery used to increase production. Hence, the government plays a large role in the country's contribution to global warming.

On the other hand, the government is also able to reduce the country's emission of greenhouse gases. For example in Singapore, our government has introduced several campaigns to increase public awareness about the effect of global warming. In order to fight against global warming, it requires the entire nation's effort. Hence, the Singapore government has also made the effort to educate its population on ways to reduce global warming. In addition, many benefits have also been introduced to encourage its population to go 'green'. Together with the benefits introduced and also knowing about the harmful effect of global warming, the population will then see the need to reduce the emission of greenhouse gases.

In short, the government can both contribute and help to reduce the problem of global warming. It depends on the message that the government brings across to its population. If the government only emphasise on the importance to remain competitive in the market and neglect on environmental friendly measures, the country will then be actively contributing to the global warming.

The World Of The Engineers Is Expanding

What is an engineer? An engineer is usually related to someone who operates those sophisticated machinery. There are several factors which affect how the engineers work and think.

These were how the majority associated the engineers in the past. However, throughout the years, with rapid industrialisation, the job scope of an engineer has expanded way beyond the above definition. In the modern society, other than knowing how to operate the sophisticated machinery, engineers also need to be responsive when problems arise. An employer will be looking more into how fast an engineer can come up with a solution should any difficulty arise rather than the proficiency of an engineer to operate those sophisticated machinery. As such, engineers of today's society are trained to be fast thinking and creative, through both tertiary education and also experience.

Globalisation has increased the demand for engineers. As a result of globalisation, there is an increasing demand for the improvement of technology and also the rate of productions so as to meet the increasing needs of the growing population. As such, engineers have to undergo frequent courses or training to upgrade their skills to keep up with the technology and remain competitive and to secure their jobs.

The demand for engineers around the world is increasing rapidly. There are also more career opportunities available for the engineers. Hence, more women are also willing to take up engineering as their course of study during tertiary education, given the increase in career opportunities.

The rising needs of the world also affect how the engineers set their priority and allocate their work. Not only do the engineers help to improve our lifestyle, they have also been working out on ways to prolong the lifespan of the Earth. Globalisation has resulted in the increasing pollution contributed to the environment and hence destroying the Earth, which is a home to every living thing. Hence, the increasing needs for environmental friendly technology urge the engineers to pay more attention and time in that sector.

In conclusion, in today's society, there is no boundary as to whether engineering is a career of the men or women. In addition, there is an increasing demand for engineers. The population has set greater expectations from an engineer today as the standard of living has increased. New technologies are expected every now and then, to provide greater luxury and convenience.
