# 3.2 Population growth and change: the impact of hiv/aids  (Page 3/4)

 Page 3 / 4

And the solution?

People must change their behaviour. This means everyone! Someone who did not have the virus has said, “The solution of the problem begins with me.” What would he have meant by this?

Learners must use the information provided in the first five to six pages to be able to do the assignments that follow.

Enjoy reading and working on this research and thinking assignment! It will not always be easy! Consider the headings carefully when you are looking for information.

## [lo 1.2]

 Use the statistics on page 37 and the predictions in figures 4 and 5 to supply the necessary numbers: In South Africa at present, about__________________ people between 15 and 59 are HIV positive. There are about ____________________AIDS orphans in our country.

## [lo 1.2]

 If the life expectancy of a country’s inhabitants increases, it will be an indication of progress. The life expectancy of the people of the Southern African Development Community (SADC) has increased, as we can see in Figure 3. Complete the horizontal column graph for the five SADC member countries according to the information in Figure 5. Draw one column only, colouring it red for the expected age with AIDS, and blue for the age that could have been reached without the AIDS catastrophe.

## [lo 1.2]

• The information in Figure 2 indicates a healthy reduction in the growth of the South African population. Death from AIDS may unfortunately reduce the growth to such an extent that it will have a negative effect on the country.
• Researchers have predicted that the reduction between 2000 and 2010 without AIDS could be 1,7%, but that it could decrease to 1,5%, with AIDS. Complete the graph according to this information. Use blue to indicate the growth without AIDS and red to indicate growth with AIDS.

## [lo 1.5]

• Collect newspaper articles dealing with this subject and display them on your notice board. Articles indicating a solution for any problem relating to AIDS should be indicated in a particular way. You can decide how.

## [lo 1.5]

• Read the newspaper articles dealing with the AIDS catastrophe that is staring our country in the face once again, think about it and discuss it with your friends. It ought to be clear that unless some plan to combat AIDS is devised soon, South Africa faces a major catastrophe.
• Write a paragraph or two about the possible problems on a separate sheet of paper. Use the following words and phrases:

## [lo 1.5]

• Near the end of the newspaper article someone is quoted as having said, “The solution of the problem begins with me.” Explain what you think this person meant in one sentence.

## [lo 3.1]

 The same truth is repeated four times in the frame alongside. In the light of the dangers for South Africa that are presented through AIDS, it is obvious that much adjustment is necessary for survival. Discuss the adjustments in the following areas that are required to meet the challenge and report your ideas to the class: the care of orphans; the skilled workers in a factory become ill and fewer; costs in the Department of Health double each year; education.

where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
learn
da
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

what is variations in raman spectra for nanomaterials
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.
Alexandre

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
