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:

P rovide your paragraph with an appropriate heading.

[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.

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.
Joe
anyone know any internet site where one can find nanotechnology papers?
research.net
kanaga
sciencedirect big data base
Ernesto
Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
characteristics of micro business
Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general
Ebrahim
in general
s.
Graphene has a hexagonal structure
