3.2.2.2 PLASTIC LIMIT
From determination point of view it is that water content at which a 3 mm thread of the soil sample does not crumble.
Fig 3.7: Illustration for determination of Plastic Limit[7] Water was added to the soil and mixed thoroughly. A ball with about 8 g of this plastic soil mass was formed and rolled between the fingers and the glass plate with just sufficient pressure to roll the mass into a thread of uniform diameter throughout its length (with the rate of rolling between 80 and 90 strokes/min counting a stroke as one complete motion of the hand forward and back to the starting position again). The rolling was done till the threads of 3 mm diameter were obtained. The soil

of soil was taken passing through 75 micron sieve was taken. Water was added to it to bring its moisture content to about 8% . The mould with base plate attached was weighed . The extension collar was attached with the mould. Then the moist soil in the mould was compacted in 3 equal layers, with 25 blows from the 2.6 Kg rammer on each layer. The extension was removed and the compacted soil was levelled off carefully to the top of the mould by means of a straight edge. Then the mould and soil was weighed. The soil was removed from the mould and a representative soil sample was obtained for water content determination. The process repeated again after adding suitable amount of water to the soil in an increasing order.
The optimum moisture content was 14%
3.3 Soil Classification
In the Indian Standard Classification System, classification of soil is done on the basis of their gradation characteristics and using Plasticity Index. Coarse grained soils that consist of more than 12% fines are classified as Silty Gravel or Silty sand if the fines are silty in character (i.e. it lies below the A-Line); They are classified as Clayey Gravel or Clayey sand if fines are clayey in character (i.e. the limits plot above the A-line on the Plasticity chart.
Coarse grained soil having 5% to 12% fines are borderline cases and are given dual symbol. The first part of the dual symbol is indicative of the gradation, while the second part indicates the nature of fines. For example, a soil with a dual symbol SW-SC is a well graded sand with clayey fines which plot above the

695 Words | 3 PagesFrom the data obtained in Tables 1-3, we were able to plot multiple graphs using excel. These graphs give a better representation of the data as seen in Figures 1-9. It can be seen that each figure shows a slight increase in CO2 production, which signifies a possible change in metabolic rate. Figures 4 and 7 show a relatively large change between the control and fox urine. The changes in slope between theses two are 0.0267 for Figure 4’s slopes and 0.0192 for Figure 7’s slopes.

155 Words | 1 PagesSuppose you need to find the fractional European call and the fractional European put options. Let the Hurst parameter be $H=0.85$, the $\sigma=0,25$, $r=0.10$, $S_{fbm} = 100$, $K = 95$, we have \begin{eqnarray*} d_1^{fBm} & = & \frac{\ln{\frac{S}{K}} + \frac{1}{2}(r( T - t) + \frac{(1)\sigma^2{( T^{2H} - t^{2H})}}{2})}{\sigma{\sqrt{T^{2H} - t^{2H}}}}\\ & = & \frac{\ln(\frac{105}{100}) + (0.10(0.25 -0) + \frac{(1){0.25^2}{0.25^{2(0.85)} - (1)0.25^{2(0.85)}}}{2}}{(0.25){\sqrt{0.25^{2(0.85)} - 0}})} \end{eqnarray*} we obtain $d^{fBm}_1= 1.0558$. We find in the normal distribution that $N(1.0558)= 0.8544$ and $N(-1.0558) = 0.1456.$
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.
Penny And Dime Lab Report
496 Words | 2 PagesIn this week’s lab we had to determine the density of a quarter, penny, and dime. My question was “How does is each coin?” Density is the amount of mass in an object. To find the density of each coin in this lab, we used a triple beam balance to find each coin’s mass and a graduated cylinder to find their volumes. With all this information, I can now form a hypothesis.
Hydrates Lab
737 Words | 3 PagesThe appearance after this period resulted in another color change back to white. The crucible, lid, and hydrated copper sulfate was weighed again to calculate the mass of water lost by dehydration (described in table 1.3). This was done by subtracting the final mass by the initial mass of the crucible, lid, and compound. The mass of the crucible would remain unchanged while the mass of the compound would be altered. This trial was repeated 3 times and 1 extra set of data was taken from 2 separate groups to include

Lb-Pglo Lab Report
678 Words | 3 Pagesn this lab, there were four objectives needed to be met. The first one was to perform a genetic transformation procedure, the second was to move genes from one organism to another using a plasmid as a vector, and the third was to manipulate tools of biotechnology. The bacteria E. coli was used to manipulate and transform. The E. coli would be tested for ampicillin resistance and a green fluorescent glow. One hypothesis made for this lab was that the bacteria that developed a resistance to ampicillin would reproduce even in the presence of the ampicillin.

An example of a organism who has multicellular cells are plants, animals, and humans. The main reason of why scientists have a hard time finding a good set of existing organisms to compare. Is neither the first set of organisms which is being compared is dying as fast as the second specimen is being examined or they just can’t find the right species.
Radish Plant Experiment
924 Words | 4 PagesAbstract: The purpose of this experiment was to determine whether the amount of topsoil would influence the growth of radish plants. It was hypothesized that if the amount of topsoil increased by 50% would increase because topsoil contains the essential nutrients which are required for proper plant growth. The principle findings indicated that a medium amount of topsoil is ideal for plant growth as the radish plant potted in 50 ml of topsoil experienced the most growth in comparison to the radish plants potted either in 25 ml or 200 ml of topsoil. Introduction: A healthy layer of topsoil comprises of a mixture of clay, sand, silt, and humus that supply the plants with vital nutrients, such as nitrogen, phosphorus, potassium and other necessary

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
Osmosis Experiment Essay
1605 Words | 7 PagesThe overall project goals and central questions that has to do with the project is mostly trying to determine the isotonic concentration of the salt in potato roots and the use of the ideal soil salt conditions for the potato plant growth. In part 2, we had to test the enzyme activity that is in the was involved in the potato, so we can also determine the ideal soil pH conditions for the potato plant growth. In part 3, we were able to test absorb the leaf pigment at various wavelengths that determine the optimum light absorption conditions and was able to make recommendations for the light conditions that would be used un greenhouses. The goal of the first project is to determine the ideal soil salt for potato roots and we can relate this to the project is to find out if Solution A or Solution B has more solute in it. The goal of this project is to determine the meaning of Osmosis.
Water Potential Osmosis Experiment
743 Words | 3 PagesThis experiment is an attempt to investigate the amount of water potential across root storage plant species. The root storage plant species that shall be used are the carrot and the potato and the method that shall be used is known as Chardakov’s method. Water potential is the tendency of water to enter or leave a cell. Water moves from an area or region of low water potential to an area of high water potential. It is important to note that the highest water potential is 0(the water potential of pure water) and the other water potential values are in negative numbers .
