Australia Day honours for community achievers
Seven
outstanding Gold Coasters have been recognised for their contribution
to the community in this year’s Australia Day Awards.
Mayor Ron Clarke said all seven had demonstrated their strong commitment to helping those in need.
“This year’s award recipients have all contributed to making a difference in the lives of others,” said Cr Clarke.
“They have devoted themselves to providing assistance and
opportunities to others, highlighting just how much of a difference
individuals can make.
“We had 50 nominees for this year’s awards and this serves as a
reminder that a strong community spirit is alive and well in our city.
“This is what makes the Gold Coast such a great place to live.
“Being able to present our seven recipients with their awards and
thank them on behalf of Council and our city is one of my favourite
duties as Mayor.”
Awards were given in six different categories, including Citizen of
the Year and Young Citizen of the Year, and presented during a special
presentation breakfast.
2009 Australia Day Awards recipients were:
Dr Thomas Challenger – Gold Coast Citizen of the Year Stephanie Toft – Young Gold Coast Citizen of the Year Albert Small and Bernie Scobie – Gold FM Community Service Award Bill Wakefield – Sports Achievement Award Leighton Upton – Environmental Achievement Award Kate Peters – Cultural Achievement Award

Cotton is a soft, affix fiber that grows around the seeds of
the cotton plant (Gossypium sp.), a plant native to humid and subtropical
regions around the world, including India
and Africa. The fiber most often is spun into yarn or filament
and used to make a soft, breathable textile, which is the most widely used
natural-fiber cloth in clothing today. The English name derives from the Arabic
(al) qutn قُطْن, meaning cotton. In the 1800s and 1900s cotton was called
"King Cotton" because of the great power it had in the market.
Cotton fiber, once it has been processed to remove seeds
(ginning) and traces of honeydew (a secretion from aphids), protein, vegetable
matter, and other impurities, consists of nearly pure roughage, a natural
polymer. Cotton production is very competent, in the sense that only ten
percent or less of the weight is lost in consequent processing to convert the
raw cotton bolls into pure fiber. The cellulose is arranged in a way that gives
cotton fibers a high degree of strength, durability, and absorbency. Each fiber
is made up of twenty to thirty layers of cellulose coiled in a neat series of
natural springs. When the cotton boll is opened, the fibers dry into flat,
twisted, ribbon-like shapes and become kinked together and interlocked. This
interlocked form is idyllic for spinning into a fine fiber.

Fan history stretches back thousands of years. Since ancient
times, fans have possessed a dual function a status symbol and a useful adornment.
In the course of their development, fans have been made of a variety of
materials and have included ornamental artwork. The simplest fans are leaves or
flat objects, waved to produce a cooler feeling. These rigid or folding
hand-held implements have been used for cooling, for air circulation, as a
ceremonial device, and as a sartorial accomplice throughout the world from
ancient times.
The earliest known fans are called 'screen fans' or 'fixed
leaf fans'. These were manipulated by hand to cool the body, to produce a
breeze, and to ward off insects. Such early fans usually took the form of palm
leaves. Some of the earliest known fans have come from Egyptian tombs. Early Assyria
and Egypt
employed slaves and servants to operate the fan. In Egyptian reliefs, fans were
of the stiff type. Tutankhamen's tomb possessed gold fans with ostrich
feathers, matching depictions on sepulcher walls. Long-handled, disk-shaped
fans were carried by attendants in ancient times and were associated with regal
and religious ceremonies. They had handles or sticks attached to a rigid side
or to feathers. Plumage of birds was used in fans, such as those of the
Egyptians and Native American Indians, that had both practical and formal uses.
In the ancient Americas,
the Aztec, Maya, and South American cultures used bird feathers in their fans.
Among the Aztec fans were used to represent merchants in illustrations of
trades. The use of various feather types had a religious suggestion. The
Paracas people of South America (modern Peru)
have left numerous examples of ancient feather fans among their mummies. In India,
the Hindi term for a fan is 'pankha'. Pictorial evidence records that the
Greeks, the Etruscans, and the Romans used fans as cooling and ceremonial
devices. In Greece,
linen was stretched over leaf-shaped frames. In Rome,
gilded and painted wooden fans were used. Roman ladies throughout the empire
used circular fans. Chinese sources link the fan with mythological and
historical characters.

A solar cell or photovoltaic cell is a mechanism that
converts solar energy into energy by the photovoltaic effect. Photovoltaics is
the field of expertise and research related to the application of solar cells
as solar energy. Sometimes the term solar cell is reserved for devices intended
expressly to confine energy from sunlight, while the term photovoltaic cell is
used when the source is undetermined.
Assemblies of cells are used to make solar modules, which
may in turn be linked in photovoltaic arrays. Solar cells have many applications. Individual cells are
used for powering small devices such as electronic calculators. Photovoltaic
arrays create a form of renewable electricity, particularly useful in
situations where electrical power from the framework is unavailable such as in
remote area power systems, Earth-orbiting satellites and space probes, remote
radiotelephones and water pumping applications. Photovoltaic electricity is
also increasingly deployed in grid-tied electrical systems.

Media bias is a term used to describe a real or supposed bias of newspapers and news producers within the mass media, in the selection of which events will be reported and how they are covered. The term "media bias" usually refers to a invasive or widespread bias contravening the standards of newspaper journalism, rather than the perception of an individual journalist or article. The direction and degree of media bias in various countries is extensively disputed, although its causes are both practical and theoretical.
Practical limitations to media objectivity include the inability of journalists to report all available stories and facts, and the requirement that selected facts be linked into a coherent tale (Newton 1989). Since it is impossible to report everything, some bias is inevitable. Government persuade, including overt and covert censorship, biases the media in some countries. Market forces that can result in a biased presentation include the ownership of the news source, the selection of staff, the preferences of an intended audience, or pressure from advertisers. Political affiliations arise from ideological positions of media owners and journalists. The space or air time available for reports, as well as deadlines needed to be met, can lead to incomplete and it sounds as if biased stories.

Electrical
resistance is a compute of the degree to which an object opposes an electric
current through it. The SI unit of electrical resistance is the ohm. Its
reciprocal quantity is electrical conductance calculated in siemens. Electrical
resistance shares some conceptual parallels with the mechanical notion of
friction.
The
resistance of an object determines the amount of current through the object for
a known voltage across the object I=V/R, where R is the resistance of the
object, measured in ohms, equivalent to Js/C2, V is the voltage across the
object, measured in volts, I is the current through the object, measured in
amperes. In metals, the Fermi level lies in the conduction band giving rise to
free transfer electrons. However, in semiconductors the position of the fermi
level is within the band gap, closely half way between the conduction band
minimum and valence band maximum for intrinsic semiconductors.

Shipping
is basic method of transporting goods and cargo. Virtually every product ever
made, bought, or sold has been exaggerated by shipping. Despite the lots of
variables in shipped products and locations, there are only three basic types
of shipments, land, air, and sea.
Land
or ground shipping can be either by train or by automobile. Trucking is easily
the most accepted form of shipping. Even in Air and Sea shipments, ground
transportation is still required to take the product from its origin to the
airport or seaport and then to its purpose. Ground transportation is typically
more affordable than air shipments, but more costly than shipping by sea.
Trucks are also much quicker than ships and rail but slower than planes.
Ground
shipping can be cheaper and less limiting to size, quantity, weight, and type
of freight than by air transport. Air transport is usually held in reserve for
products which must be sent within a shorter time frame. Shipping can more
generally refer to the transport of freight, self-determining of the mode of
transport.

A
cloud is a visible mass of condensed droplets, frozen crystals suspended in the
atmosphere above the surface of the Earth or another earthly body, such as a
moon. The branch of meteorology in which
exhaust are studied is nephology.
On Earth the condensing matter is typically
water vapor, which forms small droplets or ice crystals, typically 0.01 mm in
diameter. When surrounded by billions of other droplets or crystals they become
observable as clouds. Dense deep clouds exhibit a high reflectance throughout
the visible range of wavelengths: they thus appear white, at least from the
top. Cloud droplets tend to scatter light professionally, so that the intensity
of the solar radiation decreases with depth into the cloud, hence the gray or
even sometimes dark exterior of the clouds at their base. Thin clouds may
appear to have acquired the color of their environment or background, and
clouds illuminated by non-white light, such as through sunrise or sunset, may
be colored accordingly. In the near-infrared range, clouds would appear darker
because the water that constitutes the cloud droplets muscularly absorbs solar
radiation at those wavelengths.

Science refers to
any systematic knowledge or practice. In a more restricted sense, science
refers to a system of acquiring knowledge based on the scientific method, as
well as to the organized body of knowledge gained through such research. This
article focuses on the more restricted use of the word.
Fields
of science are commonly classified along two major lines:
Natural sciences, which study natural phenomena
(including biological life), and
Social sciences, which study human behavior and
societies.
These groupings are empirical sciences, which mean the
knowledge must be based on observable phenomena and capable of being
experimented for its validity by other researchers working under the same
conditions.

Inca
Rope bridges were simple suspension bridges over canyons and gorges to present
access for the Inca Empire. Bridges of this type were suitable for use since
the Inca people did not use wheeled transport - traffic was incomplete to
pedestrians and livestock. These bridges were an intrinsic part on the Inca
road scheme and are an excellent example of Inca innovation in engineering.
They were frequently used by Chasqui runners delivering messages throughout the
Inca Empire.
The
construction of these bridges amounted to a pair of stone anchors on each side
of the canyon with immense cables of woven ichu grass linking these two pylons
together. Adding to this construction, two additional cables acted as
guardrails. The cables which supported the foot-path were unbreakable with
plaited branches. This multi-structure system made these bridges strong enough
to even carry the Spaniards while riding horses after they indoors. However,
these massive bridges were so heavy that they tended to sag in the middle, and
this caused them to bend in high winds.
