Activity 1:

To do research on the effect that tropical cyclones have

[lo 2.1]

Read the information above on Demoina and make a list of the consequences of tropical cyclones. Look in newspapers and other sources of information for articles on tropical cyclones so as to extend your own list.

Why do tropical cyclones cause extensive flood damage but relatively little storm wind damage to an area?

What is meant by the “eye” of a tropical cyclone?

3. Why some people are at a higher risk to be affected by tropical cyclones than others

Tropical cyclones also cause great damage in the developed parts of the world, but they are usually not as disastrous. Communication systems are well developed and a large percentage of the population is thus aware of the approaching danger. They can take precautionary steps in time or evacuate the area. The construction of their houses and other buildings also makes it more likely that they will be able to withstand the storms.

However, a tropical cyclone can have very serious implications in the developing parts of the world. Firstly , these areas are densely populated and great numbers of lives can be lost, because many of these people also live in less desirable, more dangerous areas. Secondly , their houses are also often poorly constructed, which means they can be severely damaged or even destroyed during such a storm. Thirdly , these areas do not have good infrastructures which could limit or decrease the effects of such a disaster. Thus paramedics and other emergency services personnel cannot reach these people quickly enough. A substantial percentage of the deaths that occur, come about after rather than during the storm.

Activity 2:

To study the effects of cyclones on people’s lives

[lo 2.1, 2.3]

  • How can tropical cyclones cause people’s death?

4. Preventative measures: risk management and risk reduction

Even though a great deal of scientific knowledge exists regarding tropical cyclones, there is actually fairly little that can be done to prevent the damage these storms cause.

Still, there are a few things that can be done to reduce the damage to a certain extent:

Early warning systems involving satellite images, radar and weather station data can be used to predict the approach of a tropical cyclone;

Cloud seeding, a process which spreads out the energy of the cyclone and reduces the wind speed, is quite successful;

Limiting the damage it causes. This is probably the best way to handle a storm. Typical precautionary steps include the following:

  • Shutters, windows and doors are nailed shut.
  • Property is tied down, and all loose objects are packed away or tied to heavy furniture and trees so that they cannot be blown away. Flying objects usually cause great damage and can even cause people to be killed.
  • Sandbags are piled up in places where a flood is expected, to halt most of the impact of the flood.
  • People and property are evacuated from the area.

Activity 3:

To plan to aid people in a disaster area

[lo 2.3]

  1. Imagine that you are the leader of an emergency team that is sent by the Red Cross to a tropical cyclone disaster area. Devise a plan to help the affected people. What would be the first measures to take? How much time would your rescue operation take?
  2. Which precautionary measures can be taken to minimise the effect of tropical cyclones? Study the cyclone-warning pamphlet on p. 23 that is issued by the American Weather Bureau to assist you.

Questions & Answers

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

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

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
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
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
can nanotechnology change the direction of the face of the world

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?
