3.7 PILOT STUDY Pilot testing is a meaningful practice in survey instrumentation‚ as there are essential improvements that could be made through all the stages of the process (Andrews et. al.‚ 2003). Conducting a pilot study provides a researcher the opportunity to assess how effectively the research instrument was designed. Because the survey instrument is the means of collecting the information that the study intended to receive. This procedure could help in determining the changes with respect

The lecture is about traffic congestions‚ which is one of the major problems in the UK’s transport system. The lecture consists of 2 main points which are‚ firstly‚ the effects of the congestions and secondly‚ how the British government have tried to address the problem by creating the Integrated Transport Policy. The first point made by the lecturer is that overcrowded roads have its effects. First of all‚ they affect directly in the country’s economy‚ as all the lost time have its repercussion

The Central Dogma. This hypothesis was described by Crick in 1958. In 1953‚ Watson and Crick were the first to determine the true crystalline structure of DNA‚ using model building and then X-ray crystallography. Once the DNA structure was determined‚ the mechanisms behind inheritance‚ information flow‚ and gene function fell into place. Overall the flow of information is depicted as: DNA --> RNA --> protein. Both DNA and RNA can be replicated (i.e. DNA is synthesized from DNA‚ and RNA from RNA)

Direct energy conversion system Direct energy conversion systems that could operate in the 100-700°C temperature range with high efficiencies (>30%) provide an attractive compact alternative to internal combustion engines for many military applications. They will also expand the possibilities for waste heat recovery applications. The core of the solution we are proposing is a metal/semiconductor nanocomposite that will allow us to modify four intrinsic material properties in order to fabricate
