4.2 Physical Analysis 4.2.1 Density Test
Table 4.1 shows, the samples of undoped calcium phosphate pellets using various sintering temperature. From the experiment, different sintering temperatures are used such as 1000ºC, 1100ºC and 1200ºC. Each sintering temperature have five samples are being used to measure the density of the samples. After analysis, the average density will be collect and recorded. The summary that can get from the table is the mean density for 1000ºC, 1100ºC and 1200ºC sintering temperature is 3.24, 3.26 and 3.25 each respectively.
Based on Table 4.2 shows, the samples of magnesium doped calcium phosphate pellets by using different weight percentage of magnesium pellets without sintering temperature. From the experiment, different weight percentages is used such as 1.0wt.%, 1.5wt.% and 2.0wt.% .Similar with the previous explanation, five samples are being used to measure the density of the samples. The summary that we can get in this table is the mean density for 1.0wt.%, 1.5wt.% and 2.0wt.% weight percentages is 2.75, 2.66 and 2.97 each respectively.
Table 4.3 shows the density test in 1.0wt.%, 1.5wt.% and 2.0wt.% of magnesium doped calcium phosphate pellets at 1000ºC sintering temperature for five samples. The mean density of different concentration are measured based on the average of five samples.

The density of undoped calcium phosphate is 3.24 g/cm3 and highest density for magnesium doped calcium phosphate can be 3.46 g/cm3 for 2.0wt.%. These trends are in increasing pattern where the concentration of magnesium influences the result of density. It means that the sintering temperature can increase the density of the samples. This is because of the pores which are fully filled water will make the density to increase. This result is similar with journal (Matthew J Thompson,

The figures intimate the fault injected FFT,which is checked by the manual error injected via all diferent possibilities by using RTL scripting. Eventhough the soft error is added in the FFT the error detector code 100% detect the errors and corrector correct the errors.

1764 Words | 8 PagesAnderson and Wood (1925) determined a magnification value equal to 2800 but they neglected the deformation of the tungsten wire under different equilibrium situations. Conversely, the deformation of the wire could be sufficient to reduce the magnification factor of 30%, increasing the moment of inertia. For this reason Uhrhammer and Collins (1990) and Uhrhammer et al. (1996) recomputed the instrument static magnification (GS) that was estimated equal to 2080 ± 60. Using 2800 instead of 2080 in the BB WA simulations leads to a magnitude error of +0.129 (e.g. Uhrhammer et al., 2011).

798 Words | 4 PagesResults The lab experiment was done in two parts, one with the NAND, NOR, XOR and Hex Inverters and the other with a 7483 full adder gate, both will verify the truth table when two input bits and a carry are added together. The circuits were built by examining the 1 bits through a K-Map to create a Boolean expression for the sum and carry. The Boolean expression for the sum was A⊕B⊕C and the carry as AB+BC_in+AC_in. From these two expressions, we notice that we must use two exclusive-ORs gates in the sum inputs for A, B, and C. For the sum, we have to use NOR and NAND (the only available gates from the lab manual).

333 Words | 2 PagesUsing the data provided in each one of these tests it can be assumed that one has done the steps to be able to determine the magnitude and orientation of the charges of the tape in each test, thus, allowing them to apply the same principle to any object they so desired. Their results would line up with the following; that if the two pieces of tape are torn from the same 40 centimeter strip then the tops of both pieces of tape would be positive and the bottoms of both pieces of tape would be negative and that if they would double the tape the attraction or repulsion in general would lower due to the increased density. Their data would also show that two pieces of tape ripped from each other would result in one piece being entirely positive and the other being entirely negative, they would also be able to state that the orientation of how the tape is paired up doesn’t matter.

Every point acts like a new source of waves from the light. Huygens’ principle states that every point on any wave front can be regarded as a new point source of light.

Hastings Point Lab Report
1610 Words | 7 PagesIntroduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.

Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has
