Purposes for land use

The lay-out of a town or city plan shows that different areas are allocated for differerent purposes. The lay-out of any town or city must be well-planned. It would for instance be disastrous to allow an industry releasing toxic substances in a residential area. For this reason townplanners work years ahead to regulate each area regarding its functions, transport and land usage. It may however happen that the function of certain buildings change.

In Port Elizabeth for instance, many houses are now used for business purposes. The central business district has since been relocated. Close to Greenacres we are already beginning to see the head offices of banks and insurance companies. What once used to be part of the Mill Park residential area, is gradually becoming business premises.

1. Functions of land usage in South African cities

When we consider land use in an urban area, we find that certain basic functions are usually found in all cities. The total urban area usually consists of a number of developed areas, while others are still undeveloped.

The developed area usually consists of two types of areas, on for private and the other for public development.

Areas for private development

The area for private development usually includes three types of land use functions:

a) Residential – e.g. private homes, terraced houses, flats and townhouse complexes.

b) Industries – e.g. storage, light industries and heavy industries.

c) Commerce – e.g. retail, wholesale, financial and professional enterprises.

Areas for public development

The areas for public development serve four types of land functions:

a) streets

b) recreation – such as parks, sports grounds and culture

c) public services – such as hospitals, airports, cemeteries and sewerage

d) education – primary and high school

Undeveloped areas

The undeveloped areas can usually be classified under two headings:

a) unused, open areas

b) agricultural land

Activity 1:

To describe the role and function of land use

[lo 2.2]

Study this illustration of an urban area and answer the questions:

1. Where is the business district of the urban area situated?

2. Would you describe b as a high-income or a lower-income residential area? Give a reason for your answer.

3. What natural obstruction could prevent possible future expansion of the city in a northerly direction (see c )?

4. Are there adequate sporting facilities to provide in the needs of the city-dwellers?

Activity 2:

To discuss the function of land in any given environment

[lo 2.2]

nb: Teachers should note that this activity is a practical assignment that can be executed in groups of two.

2 The function of the land in my environment

Study the table and additional information and follow the teacher’s instructions to determine the use of land in your own environment.

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

Kim Reply
or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
