Whales are sea-living mammals
They therefore breathe air but cannot survive on land. Some species are very large indeed and the blue whale, which can exceed 30m in length, is the largest animal to have lived on earth. Superficially, the whale looks rather like a fish, but there are important differences in its external structure: its tail consists of a pair of broad, flat, horizontal paddles (the tail of a fish is vertical) and it has a single nostril on top of its large, broad head. The skin is smooth and shiny and beneath it lies a layer of fat (blubber). This is up to 30 cm in thickness and serves to conserve heat and body fluids.
Genetic research has produced both exciting and frightening possibilities. Scientists are now able to create new forms of life in the laboratory due to the development of gene splicing.
On the one hand, the ability to create life in the laboratory could greatly benefit mankind.
For example, because it is very expensive to obtain insulin from natural sources, scientists have developed a method to manufacture it inexpensively in the laboratory.
Another beneficial application of gene splicing is in a agriculture.
Scientists foresee the day when new plants will be developed using nitrogen from the air instead of from fertilizer. Therefore food production could be increased. In addition, entirely new plants could be developed to feed the world’s hungry people.
Not everyone is excited about gene splicing, however. Some people feel that it could have terrible consequences.
A laboratory accident, for example, might cause an epidemic of an unknown disease that could wipe out humanity.
As a result of this controversy, the government has made rules to control genetic experiments. While some members of the scientific community feel that these rules are too strict, many other people feel that they are still not strict enough.
A brief Summary of Speech Production
Speech production is made possible by the specialised movements of our vocal organs that generate speech sounds waves.
Like all sound production, speech production reguires a source of energy. The source of energy for speech production is the steady stream of air that comes from the lungs as we exhale. When we breathe normally, the air stream is inaudible. To become audible, the air stream must vibrate rapidly. The vocal cords cause the air stream to vibrate.
As we talk, the vocal cords open and close rapidly, chopping up the steady air stream into a series of puffs. These puffs are heard as a buzz. But this buzz is still not speech.
To produce speech sounds, the vocal tract must change shape. During speech we continually alter the shape of the vocal track by moving the tongue and lips,etc. These movements change the acoustic properties of the vocal tract, which in turn produce the different sounds of speech.
In Australia there are three levels of government, the federal government, state governments and local governments. All of these levels of government are necessary. This is so for a number of reasons.
First, the federal government is necessary for the big things.
They keep the economy in order and look after things like defence.
Similarly, the state governments look after the middle sized things.
For example they look after law and order, preventing things like vandalism in schools.
Finally, local governments look after the small things.
They look after things like collecting rubbish, otherwise everyone would have diseases.
Thus, for the reasons above we can conclude that the three levels of government are necessary
In all the discussion over the removal of lead from petrol (and the atmosphere) there doesn’t seem to have been any mention of the difference between driving in the city and the country.
While I realise my leaded petrol car is polluting the air wherever I drive, I feel that when you travel through the country, where you only see another car every five to ten minutes, the problem is not as severe as when traffic is concentrated on city roads.
Those who want to penalise older, leaded petrol vehicles and their owners don’t seem to appreciate that, in the country, there is no public transport to fall back upon and one’s own vehicle is the only way to get about.
I feel that country people, who often have to travel huge distances to the nearest town and who already spend a great deal of money on petrol, should be treated differently to the people who live in the city.
Moscow – A Russian journalist has uncovered evidence of another Soviet nuclear catastrophe, which killed 10 sailors and contaminated an entire town.
Yelena Vazrshavskya is the first journalist to speak to people who witnessed the explosion of a nuclear submarine at the naval base of shkotovo – 22 near Vladivostock.
The accident, which occurred 13 months before the Chernobyl disaster, spread radioactive fall-out over the base and nearby town, but was covered up by officials of the then Soviet Union. Residents were told the explosion in the reactor of the Victor-class submarine during a refit had been a ‘thermal’ and not a nuclear explosion. And those involved in the clean up operation to remove more than 600 tones of contaminated material were sworn to secrecy.
A board of investigators was later to describe it as the worst accident in the history of the Soviet Navy.
Once upon a time there lived a little girl named Snow White. She lived with her Aunt and Uncle because her parents were dead.
One day she heard her Uncle and Aunt talking about leaving Snow White in the castle because they both wanted to go to America and they didn’t have enough money to take Snow White.
Snow White did not want her Uncle and Aunt to do this so she decided it would be best if she ran away. The next morning she ran away from home when her Aunt and Uncle were having breakfast. She ran away into the woods.
She was very tired and hungry.
Then she saw this little cottage. She knocked but no one answered so she went inside and fell asleep.
Meanwhile, the seven dwarfs were coming home from work. They went inside. There they found Snow White sleeping. Then Snow White woke up. She saw the dwarfs. The dwarfs said, what is your name? Snow White said, ‘My name is Snow White’.
Doc said, ‘If you wish, you may live here with us”. Snow White said, ‘Oh could(I) ?.Thankyou’. Then Snow White told the dwarfs the whole story and Snow White and the 7 dwarfs lived happily ever after.
The Hole Game
One marble per person
A hole in ground
A line (distance) to start from
1. First you must dub (click marbles together).
2. Then you must check that the marbles are in good condition and are nearly worth the same value.
3. Next you must dig a hole in the ground and draw a line a fair distance away from the hole.
4. The first player carefully throws his or her marble towards the hole.
5. Then the second player tries to throw his or her marble closer to the hole than his or her opponent.
6. The player whose marble is closest to the hole tries to flick his or her marble into the hole. If successful, this player tries to flick his or her opponent’s marble into the hole.
The person flicking the last marble into the hole wins and gets to keep both marbles.
Natural Bridge National Park
Natural Bridge National Park is a luscious tropical rainforest.
It is located 110 kilometres south of Brisbane and is reached by following the Pacific Highway to Nerang and then by traveling through the Numinbah Valley. This scenic roadway lies in the shadow of the Lamington National Park.
The phenomenon of the rock formed into a natural ‘arch’ and the cave through which a waterfall cascades is a short 1 kilometre walk below a dense rainforest canopy from the main picnic area. Swimming is permitted in the rock pools. Night-time visitors to the cave will discover the unique feature of the glow worms.
Picnic areas offer toilets, barbecues, shelter sheds, water and fireplaces; however, overnight camping is not permitted.
Private Lives Sparkle
Since the first production of ‘Private Lives’ in 1930, with the theatre’s two leading sophisticates Noel Coward and Gertrude Lawrence in the leads, the play has tended to be seen as a vehicle for stars.
QUT Academy of the Arts’ production boasted no ‘stars’, but certainly fielded potential stars in a sparkling performance that brought out just how fine a piece of craftsmanship Coward’s play is.
More than 60 years later, what new could be deduced from so familiar a theme?
Director Rod Wissler’s highly perceptive approach went beyond the glittery surface of Witty banter to the darker implications beneath.
With the shifting of attitudes to social values, it became clear that Victor and Sibyl were potentially the more admirable of the couples, with standards better adjusted than the volatile and self-indulgent Elyot and Amanda.
The wit was there, dexterously ping-ponged to and fro by a vibrant Amanda (Catherine Jones) and a suave Elyot (Daniel Kealy).
Julie Eckersley’s Sibyl was a delightful creation, and Phillip Cameron-Smith’s more serious playing was just right for Victor. Jodie Levesconte was a superb French maid. James Maclean’s set captured the Thirties atmosphere with many subtle touches.
All involved deserve the highest praise.
