TSUNAMI the next big wave: the Grandaddy of them all
TSUNAMI the next big wave: the Grandaddy of them all
Copyright 2005 Marketing Defined. All Rights Reserved.
A few days ago on Melbourne’s 60 Minutes, renowned scientist Dr Kerry Sieh predicted that an earthquake and the ensuing next big wave or giant Tsunami will definitely happen, and it will be the Grandaddy of them all
Indonesia gets the full force this time around …
When?… whether it be in a few months, or in a decade is what he cannot accurately predict at this present moment.
Dr Sieh, a Geology professor at the California Institute of Technology, knows Indonesia’s earthquake zone like the back of his hand …
..and he did in fact predict the first earthquake that hit parts of Indonesia on Boxing Day. Now he predicts another Tsunami will hit, and this will be the grandaddy of them all!
From Melbourne MSN Channel 9’s Sixty Minutes Richard Carleton explains why the earthquakes and ensuing Tsunami’s occur:
RICHARD CARLETON: Dr Sieh’s focus is on the faultline, 5000km long, where moving plates of the earth’s crust grind against each other. The plate under the Indian Ocean slides beneath Indonesia, much like the disappearing stairs on an escalator. But some sections get stuck and then later snap upwards, releasing gargantuan force.
DR KERRY SIEH: The plates get hung up and they can’t slip past each other, so the upper plate gets dragged down as this plate sinks and with it, the islands get dragged down, slowly but surely, and when the earthquake happens, they pop back up and out.
RICHARD CARLETON: And that’s what happened last Boxing Day. The quake jolted the mainland so violently that people were thrown to the ground.
What a pointless waste of life! … Dr Sieh warned the governments concerned ahead of time .. he personally went down and alerted inhabitants of the affected villages in Indonesia to protect themselves against the Tsunami he just knew would happen
… but nobody paid any attention to him … now when he walks into these same villages, he is welcomed and treated as a hero !
From his 14 satellite research station, high in the mountain tops of the humid Indonesian jungle, Dr Sieh now predicts the next Tsunami will hit:
.. and the precise location … right opposite the city of Padang in Indonesia … inhabitants: 1 million people!
Repeat: All he cannot pinpoint is when … this disaster could be in months, the next decade or in twenty years!
The city of Padang is base for Australian surfers who go there to surf the waves of the Menwawais … where some of the best surfing breaks in the world may be found .. as an Australian citizen this alarms me greatly.
Geographically, the city of Padang would have difficulty dealing with a high tide, the devastation caused by the grandaddy of Tsunamis is incomprehensible.
Imagine a mere 15 minute warning before the earthquake ..
… and then the waters of the giant Tsunami gushing down the streets of Padang, just like it did in Banda Acheh washing everything away in its stride ..
… a moving torrent of cars, oil, broken trees and precious human life!
My call to all my fellow Marketers, the Search Engine Optimization community, Retail colleagues and anyone who reads this post: do everything in your power to reach your readers in Indonesia, particularly the city of Padang .. they need to take heed and make adequate provision to stop the pointless human slaughter this time around.
Whether this be in the form of lobbying your local Government bodies, or through local press release, we have to help this time before the devastation of this giant wave, the grandaddy of Tsunami’s .. takes away more precious human life ..
.. but above all do this in a responsible manner .. causing wide spread panic amongst unworldly village inhabitants or your worldwide audience will not help.
Melbourne’s Channel 9 has the whole story including a video of the interview available at their site . The video version is half-way down the page. Due to the ever changing nature of News, I cannot guarantee how long this link will be up.
Whilst this news is hardly topical for an internet marketing and search engine optimization Blog, as a parent the irreversible damage to our environment has me greatly concerned … please do whatever you can to stop this alarming trend.

Many of us know that solar energy is good, but few really understand why.
Therefore, I compiled a comprehensive list of solar energy advantages and disadvantages that will enable you to make an educated decision whether on not Solar Power is right for YOU.
Solar Energy Advantages
1. Saves you money
- After the initial investment has been recovered, the energy from the sun is practically FREE.
- The recovery/ payback period for this investment can be very short depending on how much electricity your household uses.
- Financial incentives are available form the government that will reduce your cost.
- If your system produce more energy than you use, your utility company can buy it from you, building up a credit on your account! This is called net metering.
- It will save you money on your electricity bill if you have one at all.
- Solar energy does not require any fuel.
- It’s not affected by the supply and demand of fuel and is therefore not subjected to the ever-increasing price of gasoline.
- The savings are immediate and for many years to come.
- The use of solar energy indirectly reduces health costs.
2. Environmentally friendly
- Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment.
- It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulphur dioxide or mercury into the atmosphere like many traditional forms of electrical generations does.
- Therefore Solar Energy does not contribute to global warming, acid rain or smog.
- It actively contributes to the decrease of harmful green house gas emissions.
- It’s generated where it is needed.
- By not using any fuel, Solar Energy does not contribute to the cost and problems of the recovery and transportation of fuel or the storage of radioactive waste.
3. Independent/ semi-independent
- Solar Energy can be utilized to offset utility-supplied energy consumption. It does not only reduce your electricity bill, but will also continue to supply your home/ business with electricity in the event of a power outage.
- A Solar Energy system can operate entirely independent, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in remote locations (like holiday log cabins), making it more practical and cost-effective than the supply of utility electricity to a new site.
- The use of Solar Energy reduces our dependence on foreign and/or centralized sources of energy, influenced by natural disasters or international events and so contributes to a sustainable future.
- Solar Energy supports local job and wealth creation, fuelling local economies.
4. Low/ no maintenance
- Solar Energy systems are virtually maintenance free and will last for decades.
- Once installed, there are no recurring costs.
- They operate silently, have no moving parts, do not release offensive smells and do not require you to add any fuel.
- More solar panels can easily be added in the future when your family’s needs grow.
Solar Energy Disadvantages
- The initial cost is the main disadvantage of installing a solar energy system, largely because of the high cost of the semi-conducting materials used in building one.
- The cost of solar energy is also high compared to non-renewable utility-supplied electricity. As energy shortages are becoming more common, solar energy is becoming more price-competitive.
- Solar panels require quite a large area for installation to achieve a good level of efficiency.
- The efficiency of the system also relies on the location of the sun, although this problem can be overcome with the installation of certain components.
- The production of solar energy is influenced by the presence of clouds or pollution in the air.
- Similarly, no solar energy will be produced during nighttime although a battery backup system and/or net metering will solve this problem. See www.dsireusa.org for details on how net metering allows you to save electricity and money.
- As far as solar powered cars go - their slower speed might not appeal to everyone caught up in today’s rat race.

Mesothelioma has a few primary symptoms. The primary symptom of pleural mesothelioma is a lack of breath as a consequence of pleural effusion ” the buildup of fluid in the pleura, or membrane, surrounding the lung. Another common symptomis chest pain due to the tumor invading the chest wall. Additional symptoms include night sweats, weight loss and exhaustion.
The main indicatorof patients with peritoneal mesothelioma, which originates in the abdomen, is the swelling of the abdomen because of fluid accumulation (ascites), abdominal pain, and bowel obstruction.
It is important to note that these symptoms could be caused by a myriad of diseases or conditions. But if you have experienced any of these symptoms and have had asbestos exposure, you should see your doctor.
Peritoneal mesothelioma is hard to identify, because less serious conditions also cause similar symptoms. These symptoms include:
- Difficulty breathing
- Chest or lower back pains due to accumulated fluid in the pleura
- Running a temperature
- Vomiting
- Raspy voice
- Difficulty swallowing
- Spitting up blood
Do not attempt self-diagnosis. People suffering from the above symptoms should remain calm and consult a doctor. Performing a biopsy is the standard way to confirm the condition. A pathologist takes a small tissue sample from the suspicious area and examines it to return a highly accurate diagnosis. Biopsies are generally not painful.
Another option is a CT (Computed Tomography) scan. This is an X-ray procedure where a scanner takes many cross-sectional images as it rotates around the body. Once in a while, a dye is ingested by the patient to help define the images. CT scans have the advantage of being non-invasive and easier, and they are recognized as being effective in diagnosis. Opinions vary whether a CT scan or biopsy is cheaper. If there are abnormalities, a biopsy may also be needed to know if the abnormality is a tumor, and if thats the case, if its malignant or benign. Diagnosis of pleural mesothelioma is also possible by looking for cancer cells in a sample of fluid from the pleura.
These methods can also diagnose and screen patients for mesothelioma. Patients who may think they are at risk but do not display any symptoms are typically screened, to make sure they are not in danger or to catch the cancer as early as possible. People who need to be screened include those with a history of asbestos exposure..

Algebra as a Science
Algebra is thought a crucial arm of maths which explains how to deal with all situations involving numbers and variables. By default, there is so much to articulate about teaching and learning of Algebra as a generalized arithmetic which goes through systematic mathematical procedures such as induction, generalization and proof. So, bit by bit, students get various ways to enhance their Algebra level, for example by getting the information from tutors or packages, which provide bit by bit illustrative solutions. Software Packages designed for algebra studying provide all the available methods for solving particular problems with a technological touch. Many students are not even aware of the full potential of algebra! They complain about its impracticality ignoring that Algebra, generally maths, teaches their mind how to think logically and correctly. The typical way to learn Algebra is in school, from being a kid till becoming an adult pupils get their information from the teacher. With the advancement of engineering science, new techniques have been disciplined to learn Algebra, such as using software packages which is a more convenient way to learn Algebra. These software programs deliver information in a forward-moving approach in to student’s brains.
Algebra’s Covered Area
Same as any other branch of science, Algebra handles a lot of domains and includes many theories and concepts. Gcf, or Greatest Common Factor, is one such concepts. Gcf means to rewrite the polynomial as a product of simpler polynomials or of polynomials and monomials. Other attached area is simplifying fractions which enables an individual to get a simplified result. Quadratic function represents any function which is a solution of a quadratic polynomial. Multiplying and Dividing fractions is also an key area of standard Algebra. A person can multiply and divide with radicals only if the index, or root, is the same. Other connected areas are Adding and Subtracting Radicals; an individual can add or subtract radical terms only if both the index and the radicand are the same. Matrix operations include adding, subtracting, multiplying and dividing . Other important areas are finding x-intercept of a line and y-intercept of a line - to get the x-intercept of a line, substitute zero for y in the equation and vice versa for finding y-intercept of a line.
