In the physical feature of peat, a range of 100% to 1300% of field water content in peat could result in high buoyancy and high pore volume which in turn leads to low bearing capacity and bulk density. The above Table 2.2 also shows that fibrous peat water tends to be in the range of 489% to 1590%. According to Huat (2004), fibrous peat likely to have higher water content than humified peat and a decrease of mineral content tends to increase the water content in peat. East Malaysia peat recorded a range of 200% to 2207% of natural water content (Huat, 2004). The typical bulk density for peat is noted within the range of 0.84 to 1.23 Mg/m3 in Table 2.2. However, Hobbs (1986) stated that the bulk density of peat is typically similar to or less than that of water due to the presence of entrapped gases in peat. The values of bulk density in peat usually remain relatively constant at the range of 1.03Mg/m3 and do not vary with the properties of peat (Hobbs, 1986). Meanwhile, peat have a tendency to be acidic depending to the rock types in the area draining into the peat land (Huat, 2004). The recorded pH in Table 2.2 displays the peat range from acidity of 3.3 to slight neutral alkaline condition of 7.3 in common. According to Davies et al. (2010), peat in Malaysia has pH levels as low as …show more content…
The results showed that approaching failure was not seen even the shear stress was beyond 140kPa for both remoulded peat and remoulded peat fibre and the tests had to be stopped due to over axial compression on the peat samples. The samples however showed gradual transition from a linear elastic to a linear strain-hardening stress–strain response up to 5% for both remoulded peat and remoulded peat fibre specimens (Hendry, 2011). Michalowski & Cermak (2002) had observed this behaviour which similar in the fibre-reinforced sand triaxial tests and believed that the increasing reinforcement perpendicular to the major principal stress direction could be the
Holly Weiss SC-131 Unit 7 Acidosis and Alkalosis Assignment The normal pH value for the body fluids is between pH 7.35 and 7.45. When the pH value of body fluids is below 7.35, the condition is called acidosis, and when the pH is above 7.45, it is called alkalosis. Respiratory acidosis is a condition that occurs when the lungs cannot remove all of the carbon dioxide the body produces.
Something I learned about in Herbology 301 is healing. Healing is an important part of our life, which is why i wanted to write about it. Healing spells are needed in everyday life, and if we were to ask someone how many healing spells they 've used in their lifetime, the number would probably be too high to remember. I also learned that mental illnesses are not one-spell-cure-all diseases, which is very helpful to know.
phosphates and nitrates ) - which is when fertilizers < such as those on farms > can seep through the soil or even run down the soil - called runoff - into the creek causing the water to have more nutrients than it should. ) Depending on how much pollution there is depends on how much algae there is ( the more eutrophication -there is the more nutrients in the water- results in how much algae there will be.) We were also testing on the pH scale ( which measures the acidity or alkalinity of water ) goes from 0 - 14 where 6 - 0 is higher acidity and 8 - 14 is higher alkalinity ( alkalinity is what neutralizes/destroys acid. ) 7 on the pH scale is neutral and that is the ideal water for the ecosystem. The pollution that we were testing for is where the acid came from to begin with.
There are factories located relatively close to the wetland, which release gases and smoke affecting the biophysical processes in the

During the 18th century there was many technology advances some that changed society in a positive manner and some that influenced negatively. In 1800 Eli Whitney invented the cotton gin, this invention helped the industry in a positive way. The cotton gin was able to remove the seeds from cotton in a more timely manner. In the United States the removal of the seeds from cotton was done by slaves,with the ability to remove the seeds faster it helped to put an end to slavery.

4. Habitat alteration: Removal and reduction of natural habitat by flooding, soil erosion and water
I organized four different tests; pH paper, alkalinity tests, the number of rocks neutralizing acid, and the number of rocks that don’t neutralize acid. The average for pH paper was seven. The pH is the numeric scale used to specify the acidity or alkalinity of an aqueous solution. The pH scale measures acidity and alkalinity. the pH scale goes from zero, which is an acid reading, to fourteen, which is an alkaline reading.
The vegetation at Mount William were originally covered by dry sclerophyll forest, however the quarry area have the long history of European disturbance including the clearance for grazing and
The findings of this project must however been subjected to some scrutiny as the plots were situated in disturbed areas of savannah. This could have a direct effect on the number of species in the area and therefore greatly change the conclusion of this research. However, the biome the plot was situated was still savannah and thus adequate conclusions can still be drawn from the
Alkalosis & Acidosis Shalita Johnson SC131 Respiratory Acidosis: This is a condition that occurs when the lungs cannot remove enough carbon dioxide that is produce by the body. When the body have excess carbon dioxide (CO2) this causes the pH of the blood and other body fluids to decrease, this make them acidic. This can be known as ventilatory and respiratory failure. Normal range: PaCO2 35-45 mmHg. pH levels are 7.35 to 7.45.
I could not forget the excitement I had waking up in the morning and running straight to the Lego structures deciding how to build a certain structure and a daydream I had of imagining of actual being built in real life. / deciding how to build a certain structure. The snapping and fitting of bricks, rods and gears captivated me for countless hours. Every Lego brick I laid down furthered my interest in designing and engineering.
Research Questions: What effect does acid rain have on the growth rate of plants in the wetland ecosystem? What results are expected? What is your conclusion? Hypothesis: Acid rain will have a negative impact on the plant growth in the wetland environment, this will result in plants dying and
