Example Of Research Paper Introductions

On the verge of writing a research paper, you should prepare an introduction. These few dozens of sentences will form the imaginary about the whole investigation. You should explain the topic you have chosen and tell about the importance and actuality of your investigation. This could be a strange idea to write the beginning after composing the whole essay, but you should try to follow it.

What Is Introduction Paragraph for Research Paper

If your exploration were a human, the introduction would be the best way of acquaintance. Besides, the intro should be concluded a thesis statement. This part of your work is aimed to help the reader to define if he or she wants to read the paper at all. Intro paragraph or even few paragraphs are usually placed at the beginning of the research paper. Moreover, all that you write in the inception should attract the attention of the reader.

How to Write a Research Paper Introduction

After writing the essay, you will have the broad picture. This will help you spot the main points and include them into an intro. These tips will attract your reader’s attention, provide interest to read the whole essay, define the thesis statement and arrange the background of your theme. There also few simple tricks which can help you make your research paper introduction the best one:

  • Declare Your Research Theme

The first sentences should be common about the broad topic. Then you should tell about your topic. This is called an inverted triangle when you start with the broad theme and then narrow it.

If you write a research paper in humanities, you can start the inception with a quotation, life story or even an anecdote. If your investigation area is science or medicine, you can write an extremely interesting fact or even shocking fact. Such approach will help you make your research paper introduction attractive.

You should explain key terms and concepts in the introduction to avoid reader’s confusion later. Make your investigation clear and understandable.

You should find your own ideal size of the introduction. It should be short enough to be readable and gain the attention of the reader and long enough to explain all of the main features of your exploration.

The key words should be used in the introduction. The aim of this trick is to make your research paper easier to be found. These could be separate words or word combinations, which define your topic.

You should be consistent in writing. Logical links between the sentences will make your text coherent.

Research Paper Introduction Example

The theory is good, but the practice is quite another. Of course, to write an excellent introduction you need to read an example, so here you are.

The bookish marketing nowadays becomes digital because of the demands of the modern online era. Such popular best seller authors like J. K. Rowling or Dan Brown get profit from the internet and use it as a source for advertising to show the audience their creation. On the other hand, a lot of writers find digital Epoque harmful and destructive for their creations because many users can get their books for free, giving no income to the author. However, there are more and more studies which reveal the business side of bookish industry not far from a negative side. This research paper will define whether the culture of digital bookish consumption has to be changed because the creations of writers become worthless due to an act of web pirates and because people have stopped valuing books according to their merit.

Worldwide, many bacteria are showing resistance to antibiotics. This is becoming a major problem for health care professionals; for example, multiple strains of a potentially deadly bacteria, Staphylococcus aureas, are already resistant to all antibiotics except vancomycin. The reports of vancomycin resistant strains of S. aureas, which appeared from three different areas of the globe last year, sent shock waves through the medical community (Levy, 1998).

Escherichia coli (E..coli) is another bacteria that is beginning to show signs of antibiotic resistance. E.coli is a rod shaped bacteria which inhabits the human colon, living off organic material which would otherwise be eliminated with the faeces. E. coli and the other intestinal flora may make up 40% of the mass of faeces and as a result E. coli is used as an indicator species to detect contamination of lakes and streams by untreated sewage. Under normal conditions E. coli is harmless but some strains can cause blood poisoning, urinary tract infections, diarrhoea and kidney failure, illnesses that are more common in people who have weakened immune systems.In most cases these E. coli infections can be successfully treated with antibiotics such as ampicillin and chloramphenicol; however, some of the strains, such as those that cause urinary tract infections, have been shown to be resistant to certain antibiotics (Morrell, 1997, Levy, 1998). This experiment aimed to test the sensitivity of four E. coli strains (EC1, EC2, EC3, EC4), isolated from patients in a local hospital, to the antibiotics, streptomycin and chloramphenicol.It was hypothesised that separately both drugs would deter bacteria growth but that a combination of both drugs would be most effective.

Toads and rats are both vertebrates of similar size. Their physiology, however, is quite different, as toads are ectothermic and rats are endothermic (Campbell et al., 1997, pg. 487). Toads regulate their body temperature through behaviour. Rats have a high metabolic rate. They maintain their body temperature at 37 degrees Celsius.In this study, the anatomy of the toad and rat were investigated.   Background to the experiment.
Technical words are not defined.
How does this information relate to the previous information? The presentation of information in the introduction needs to be building the case for defining the gap in the research this study aims to fill.
Although the aim of the research is outlined here, the reason for making this comparison has not been established. The hypothesis or expected result of the research has also not been stated.

A example of a good introduction to an Engineering scientific report

Advanced ceramic materials such as zirconia have great potential as substitutes for traditional materials in many engineering applications; however, problems such as difficulties in producing products of reliable and consistent quality and high manufacturing costs have thus far restricted their use by engineers.

Difficulties in achieving reliable and consistent quality stem largely from the formation of thermal gradients that often occurs during conventional sintering processes. Slow, controlled heating and cooling rates have been used to solve this problem. While this solution facilitates the manufacture of high quality components, it does so at the expense of production rate, and deterioration of the mechanical properties of the ceramic because of an increase in grain size. This solution, therefore, achieves quality at the expense of an economical production rate.

Recently, interest has been growing in alternative sintering techniques that could overcome the problem of thermal gradients more economically. One of the most promising is the use of microwaves to sinter ceramic compacts. Microwave sintering has many attractive features, including rapid volumetric heating and low cost. It may have other advantages as well, as there is some evidence that the mechanical properties of microwave-sintered ceramics are superior to those of conventionally-sintered eramics. This superiority has been largely attributed to the smaller grain sizes resulting from the short, rapid sintering cycle.

Until now, there has been no report of any systematic study of the microstructures produced by microwave sintering, or their relationship to the properties of the sintered product. The aims of this project were to compare the resultant properties and microstructure with material sintered by conventional constant heating rate rocesses. The relationships between density and grain size were studied. It was predicted that microwave sintering would alter the densification/grain growth relationship. The effects of heating rate and yttria content were also investigated. It was predicted that yttria content of ceramics sintered onventionally or by microwave would not differ.
