Graph 3.1 shows the rate of heat transfer due to ventilation, through the window, door and wall over a period of 7 days. The total rate of heat transfer for all components are also plotted in the graph. The rate of heat loss fluctuated with respect to time for all components and recorded maximum and minimum rates at similar times. The rate of heat transfer through the door is not only the highest in values but also in variation in temperatures. A more detailed representation of the data…

Water pollution is when our water steams, and rivers get polluted by harmful things. Water pollution in Georgia today is a very disastrous issue. The problem with water pollution is contamination from chemical spills, burst pipelines and toxic waste. Water pollution is a major issue to be dealt with. There are many ways water pollution can be avoided. In addition to finding a solution to this problem, The Clean Water Act was made and passed. Even though Water pollution very harmful, People have…

process. The conclusion to objective four states that the farmer’s capacity to adapt is very limited due to the various daily obstacles faced including lack of resources, information, financial capacity and lack of support from the government. Lack of surface water for crop production remains the most serious limitation to adaptive capacity, followed by inability to access farm credit services and improved…

There was much more pollution around this area than I had previously expected. As soon as I came into view of the bridge, I could already see a glass bottle floating down beneath it. I investigated the surface of the water and the concrete areas under and around the bridge, and I discovered that the most common types of pollution were glass/plastic bottles, cigarette butts, plastic bags, and food containers that come from large fast food chains, like KFC…

type as well as the physico-chemical make-up of the soil. Soils generally fail in shear. At failure, shear stress along the failure surface (mobilized shear resistance) reaches the shear strength, Holtz and Kovacs (1981). The soil grains slide over each other along the failure surface. No crushing of individual grains. At failure, shear stress along the failure surface (t) reaches the shear strength (tf). Using the Mohr – Coulomb criterion, Figure 10.1, we have in terms of effective stresses…

where the pesticide was applied will have the highest concentrations. As you move away from those areas the concentration should decrease. Although they can remain high due to runoff, and wind deposits. The soil depth must also be considered. The surface soil will have the highest concentration. As the pesticide leaches through the soil the…

Introduction The urbanization of a catchment is a drastic change in land use, and has major effects on the hydrological cycle during heavy rainfall events because of its impermeable surfaces (G. E. Hollis). By recording the discharge in a catchment the data can be used to create a hydrograph. It is often useful to analyse a hydrograph because it shows how quickly rainwater moves to the stream channel (Holden J. 2012.) The aim of this study is to compare an urban and rural catchment, and to find…

Erik Vargas 11/7/2017 Period 1 Water Erosion Purpose The purpose of this lab is to examine the streamflow and how it removes soil from the banking over time. Background Information “Water erosion comes in several different forms with various causes. No matter the differences, we humans can have a large impact on our water quality and erosion rates. While the causes of erosion by water are generally natural, we can play a large role in reducing water erosion, and preventing water…

The Pacific Northwest was once full of an abundance of untapped resources, it was barely populated and was the definition of a hinterland. As the Pacific Northwest started to become known and resources started to become majorly exploited and shipped, we slowly become what we are now, not a hinterland. After all the overuse and misuse of the land we are not and will never hinterland again. The definition of a hinterland is defined as parts of the country that is less developed and…

Poison Dart frogs A popular poison found in nature is Poison Dart Frogs. These frogs live in rainforest habitats in Central and South America and some in the Hawaiian Islands. The name Poison Dart Frog is a name of a group of frogs in the family dendrobatidae. The frogs are mostly bright colored and are diurnal, which means they come out during the day and sleep at night. As usual, Poison Dart Frogs have a delivery system. The article, Poison Dart Frogs, by Vera L. Figueiredo says “The toxins…
