Abstract: A novel three-point method using a grating eddy current absolute position sensor (GECS) for bridge deflection estimation is proposed in this paper. Real spatial positions of the measuring points along the span axis are directly used as relative reference points of each other rather than using any other auxiliary static reference points for measuring devices in a conventional method. Every three adjacent measuring points are defined as a measuring unit and a straight connecting bar with

Neutralization experiment AIM:- To investigate how heat is given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl)‚ Sulphuric acid (H2SO4) etc. An alkali is a

Determining the Solute Concentration of a Potato Aim: In this investigation I am going to work out the sugar concentration of a potato. I aim to find this out by putting potato cores into various concentrations‚ measuring the mass before and after. Due to osmosis the potato cores will change in mass to make the concentrations at an isotonic level‚ helping us to work out the mass of the potato. I predict that potato in the weaker solutions will gain mass‚ because some water will be absorbed by the

amylase which catalyses the breakdown of starch to produce sugars such as maltose (Sherwood‚ 2013). When testing the effect of the salivary amylase concentration‚ we observed that the solution containing the most saliva (3ml)‚ become colourless faster than the solution which contained the least saliva (1ml). This proves that an increase in enzyme concentration (increase in saliva)‚ will cause an increase in the reaction rate (Bennett and Frieden‚ 1969).

My proposed concentration in the Creative Arts Diploma would be musical theatre. I have been doing theatre for most of my life‚ and i feel it has really impacted me as a person. Studying musical theatre is very important to me because I feel as I can grow as a learner and as a performer by taking CAP. The CAP program s very intriguing to me and I hope to get better at musical theatre wise‚ and I also feel by being in CAP‚ there are some skills that will help me in school life. For example‚ project

According to the cointegration analysis established in the mid-80s‚ the non-stationarity of the underlying time series does not always imply the non-stationarity of the linear combinations of these series. Hence‚ it is a prerequisite to ensure that all variables are integrated of order one in levels before employing the panel cointegration tests. Table 3 presents the results performed by Im‚ Pesaran and Shin unit root test of all variables for the four panels of economies tested in both levels

In the experiment‚ as the size of the cube decreased‚ the absorption rate increased‚ showing that the smaller cells absorbed more sodium hydroxide than bigger cells. The smaller cells were able to absorb more sodium hydroxide as they have a bigger surface area to volume ratio causing them to act more efficiently than the bigger cells. The smallest cell had a ratio of 1:12 while the biggest cell had a ratio of 1:2‚ leaving a gap of 5:12 causing the bigger cell to act less efficient in absorbing the

Title: To Investigate the Effect of Concentration on the Rates of Diffusion. What is the relationship between concentration of hydrochloric acid and the rate of diffusion? Abstract The research question that this report is going to discuss is “What is the relationship between concentration of hydrochloric acid (HCl) and the rate of diffusion?” My hypothesis for this research question is that change in rate of diffusion will be observed when the agar
