Kangaroo Paw Flowers


The size, flower-stalk height and color of kangaroo paws flowers vary between the species. Many new forms have also arisen as the result of deliberate hybridization. The overall color of the flowers is influenced by fine colored hairs which cover the flowers and, sometimes, part of the stalk. The flowers appear over spring and summer.

The flowers are pollinated by birds. The long flower-stalks usually rise above the undergrowth and 'advertise' the presence of nectar in the flowers. The stalks also provide a perch for visiting birds.
The shape of the flowers and the position of the pollen-bearing anthers is a feature which allows pollen to be deposited on the head of feeding birds. This pollen is transferred from flower to flower as the birds feed. Different species usually deposit pollen on different areas of the birds' head. This means that pollen from one species is unlikely to be deposited in the flowers of another species.

Petronas Twin Towers

The 88-storey Petronas Twin Towers (KLCC) is the world's tallest twin structures. Located in the heart of the capital city, the crown of the Kuala Lumpur contains a complex of office buildings, conference halls, a sprawling park and an up market shopping complex.

Inspired by the geometric shape found in Islamic architecture, this gleaming mega-structure was designed by Argentinean-American architect Cesar Pelli.

Stretching out to one side of this architectural masterwork is the airy and wonderfully landscaped KLCC Park. Other attractions at KLCC are Suria Shopping Complex, Petronas Philharmonic Hall, Petrosains Science Centre, Petronas Art Gallery and Kuala Lumpur Convention Centre, where The Aquaria Oceanarium is situated.

Visiting the sky bridge is a great experience; it is open to visitors between 8.30am - 5.00pm from Tuesday to Sunday.

“shooting star” is not a star

A "shooting star" has nothing to do with a star. These wonderful stripes of light that you can infrequently witness in the night sky are caused by small bits of filth and rock called meteoroids falling into the Earth's atmosphere and blazing up. The short-lived trace of light which is produced by burning meteoroid is called a meteor. Meteors are generally called falling stars or shooting stars. If any fraction of the meteoroid survives and actually strikes the Earth, that left behind bit is then called a meteorite.

At definite times of year, you are probable to see a large number of meteors in the night sky. These actions are called meteor showers and they happen when the Earth passes through the trail of debris left by a comet as it orbits the Sun. These showers are given names based on the constellation present in the sky from which they appear to originate. For example, the Leonid Meteor Shower, or Leonids, appear to originate in the constellation Leo. It is important to understand that the meteoroids (and therefore the meteors) do not really originate from the constellations or any of the stars in the constellations, however. They just appear to come from that part of the sky because of the way the Earth encounters the particles moving in the path of the comet's orbit. Associating the shower name with the region of the sky they appear to come from just helps astronomers know where to look!

NEPTUNE


Neptune was initially experiential by Galle and d'Arrest on 1846 Sept 23 very near to the locations independently predicted by Adams and Le Verrier from calculations based on the observed positions of Jupiter, Saturn and Uranus.

Neptune's composition is almost certainly similar to Uranus': various "ices" and rock with 15% hydrogen and a little helium. It has no distinct internal layering but rather to be more or less uniform in composition. But there is most likely a small core like the mass of the Earth of rocky material. Its atmosphere is mostly hydrogen and helium with a small amount of methane.

Neptune is in blue color because of absorption of red light by methane in the atmosphere but there is some additional as-yet-unidentified chromophore which gives the clouds their rich blue tint.

Neptune has been tripped by only one spacecraft, Voyager 2 on Aug 25 1989. But fortunately, recent ground-based and HST observations have added information.

Jupiter

Jupiter (pronounced /'d?u?p?t?/) is the fifth planet from the Sun and the largest planet within the solar system. It is two and a half times as enormous as all of the other planets in our solar system combined. Jupiter, next to Saturn, Uranus and Neptune, is classified as a gas giant. Together, these four planets are sometimes referred to as the Jovian planets; somewhere Jovian is the adjectival form of Jupiter.

The planet was known by astronomers of ancient times and was connected with the mythology and religious beliefs of many cultures. The Romans named the planet subsequent to the Roman god Jupiter. When view from Earth, Jupiter can arrive at an apparent magnitude of -2.8, creation it the third brightest object in the night sky after the Moon and Venus.

Strawberry

The strawberry (Fragaria) (plural strawberries) is a type of plants in the family Rosaceae and the fruit of these plants. There are more than 20 named types and a lot of hybrids and cultivars. The most frequent strawberries grown commercially are cultivars of the Garden strawberry. Strawberries have a taste that varies by cultivar, and range from quite sweet to slightly tartlet.

Business cluster

A business cluster is a geographic combination of interconnected businesses, suppliers, and associated institutions in a particular field. Clusters are considered to increase the output with which companies can compete, nationally and globally.

This idea, also known as a spirited cluster, industry cluster or Porter's cluster, was first urbanized by Michael Porter in 1990. Cluster development has since developed into a focus for many government programs. The next development of the concept of interorganizational networks in Germany and practical growth of Clusters in the UK.
