Gadget gurus preach words of wisdom
Are
you terrified by technology or baffled by anything with batteries? If
so then you are invited to take advantage of Council’s Broadbeach
Branch Library’s ‘Techno Expo’.
The ever popular program is back again with free workshops on offer all day, Thursday 12 February 2009, between 9am – 7pm.
Community and Cultural Development Chair Cr Bob La Castra, said this
year’s program included a whole host of new and exciting sessions.
“Our gadget gurus will teach you all about mobile phones, MP3 players, digital still and video cameras,” he said.
“You will get 15 minutes of one-on-one time with one of our resident
gadget gurus who will answer your questions, show you the basics and
direct you to troubleshooting resources on your gadget of choice.”
Cr La Castra reminded those attending to bring along their gadget,
instruction booklet and any cables that connected their gadgets to a
computer to the sessions.
“It’s frustrating enough that you own something you can’t use properly – so don’t forget to bring these important items.”
“One of the other popular sessions will no doubt be the ‘digitising
your family photos’ session where you can learn how to create and store
digital copies of those important family photos,” he said.
“Our ‘online video editing and sharing’ session will also show you
how to share photos and videos online which means that you can keep
your family and friends up to date with your latest family movies and
happy snaps.”
Cr La Castra said seats were filling fast for Broadbeach Branch Library’s Techno Expo and that bookings were essential.

Acid rain is rain or any other
form of precipitation which is unusually acidic. It has dangerous effects on
the environment and on structures. It is mostly caused by emissions due to
human activity of sulfur and nitrogen compounds which respond in the atmosphere
to produce acids. In recent years, many governments have introduced laws to lessen
these emissions. Both lower pH and higher aluminum concentration in the surface
water that occur as a result of acid rain can cause damage to fish and other
aquatic animals. At pHs lower than 5 most of the fish eggs would not hatch and
lower pHs can kill adult fish. As lakes become more acidic biodiversity is also
reduced. Soil biology can be critically damaged by acid rain. Some tropical
microbes can quickly consume acids but other microbes are incapable to tolerate
low pHs and are killed. The enzymes of these microbes are denatured by the
acid. The hydronium ions of acid rain also mobilize toxins and filter away
essential nutrients and minerals

The
coconut palm is grown throughout the tropical world, for decoration as well as
for its many cooking and non-culinary uses, virtually every part of the coconut
palm has some human use.The flowers of the coconut palm are polygamomonoecious,
with both male and female flowers in the similar inflorescence. Flowering
occurs continuously, with female plants producing seeds. Coconut palms are
believed to be largely cross-pollinated, although some dwarf varieties are
self-pollinating. Coconut water can be used as an intravenous fluid.
Nearly all parts of the coconut palm are useful,
and the palms have a comparatively high yield, it therefore has important
economic value. The name for the coconut palm in Sanskrit is kalpa vriksha,
which translates as the tree which provides all the requirements of life. In
Malay, the coconut is known as pokok seribu guna, the tree of a thousand uses.
In the Philippines,
the coconut is generally given the title Tree of Life. The white, fleshy part
of the seed is safe to eat and used fresh or dried in cooking

A ghost is said to be the phantom of a deceased person, normally similar in emergence to that person, and usually encountered in places he or she frequented, or in association with the person's former belongings. The word "ghost" may also refer to the character or soul of a deceased person, or to any spirit or evil spirit. Ghosts are often associated with hauntings, which is, according to the Parapsychological Association, "the more or less regular incidence of mystic phenomena associated with a particular locality (especially a building) and usually attributed to the activities of a discarnate entity; the phenomena may include apparitions, poltergeist disturbances, cold drafts, sounds of footsteps and voices, and various odours." Ghosts are a notorious inconsistent phenomenon. According to a poll conducted in 2005 by the Gallup Organization, about 32% of Americans believe in the subsistence of ghosts. The term ghost has been replaced by phantom in parapsychology, because the word ghost is deemed unsatisfactorily precise.

A bottle is a small pot with a neck that is narrower than
the body and a "mouth." Bottles are often made of glass, plastic or
aluminum, and typically used to store liquids. e.g. water, milk, soft drinks,
beer, wine, cooking oil (for both cooking and as fuel), medicine, liquid soap,
shampoo, ink, etc.
For some bottles a place is paid, which is returned after
returning the bottle to the retailer. For other glass bottles there is often
separate rubbish collection for recycling. A device used to close the mouth of
a bottle is called a bottle cap (external), or stopper (internal). A bottle can
also be sealed using initiation sealing.
The glass bottle was an important development in the history
of wine, because, when combined with a high-quality stopper such as a cork, it
allowed long-term aging of wine. Glass has all qualities required for long-term
storage. It also ultimately gave rise to "chteau bottling," the
practice where an estate's wine is put in bottle at the source, rather than by
a merchant. Prior to this, wine would be sold by the drum and put into bottles only at the merchant's
shop, if at all. This left a massive and often abused opportunity for fraud and
corruption, as the final consumer had to trust the merchant as to the contents
of his or her glass. It is thought that most wine consumed outside of
wine-producing regions had been tampered with in some way. Also, not all
merchants were especially careful to avoid oxidation or pollution while
bottling, leading to large bottle distinction. Particularly in the case of
port, certain conscientious merchants' bottling of old ports fetch higher
prices even today.

Computers take plentiful physical forms. The first devices
that be similar to modern computers date to the mid-20th century (around 1940 -
1945), although the computer concept and various machines similar to computers
existed earlier. Early electronic computers were the size of a large room, strong
as much power as several hundred modern personal computers. Modern computers
are based on relatively tiny integrated circuits and are millions to billions
of times more capable while occupying a fraction of the space.
Today, simple computers may be made small enough to fit into
a wristwatch and be powered from a watch battery. Personal computers in various
forms are icons of the Information Age and are what most people think of as
"a computer"; however, the most common form of computer in use today
is the surrounded computer. Embedded computers are small, simple devices that
are used to control other devices, for example, they may be found in machines
ranging from fighter aircraft to industrial robots, digital cameras, and
children's toys.
The ability to store and execute lists of instructions
called programs makes computers extremely versatile and distinguishes them from
calculators. The Church–Turing thesis is a arithmetical statement of this
versatility: any computer with a certain minimum capability is, in principle,
capable of performing the same tasks that any other computer can perform.
Therefore, computers with potential and complexity ranging from that of a
personal digital assistant to a supercomputer are all able to perform the same
computational tasks given enough time and storage capacity.

A
tsunami is a series of waves shaped when a body of water, such as an ocean, is
rapidly displaced. Earthquakes, group movements above or below water, volcanic
eruptions and other underwater explosions, landslides, large meteorite impacts
and testing with nuclear weapons at sea all have the potential to produce a
tsunami. The effects of a tsunami can range from imperceptible to devastating.
The word tsunami comes from the Japanese words meaning harbor and wave. For the
plural, one can either follow usual English practice and add an s, or use an
invariable plural as in Japanese. The term was created by fishermen who
returned to port to find the area neighboring their harbor devastated, although
they had not been conscious of any wave in the open water. Tsunamis are general
throughout Japanese history; approximately 195 events in Japan have been recorded.
A tsunami has a much smaller amplitude (wave
height) offshore, and a very long wavelength, which is why they generally pass
unobserved at sea, forming only a passing bulge in the ocean. Tsunami have been
historically referred to as tidal waves because as they approach land, they
take on the characteristics of a vicious onrushing tide rather than the sort of
cresting waves that are formed by wind action upon the ocean. Since they are
not really related to tides the term is considered misleading and its treatment
is discouraged by oceanographers.

Mental health is a concept that refers to a human
individual's emotional and psychological well-being. Merriam-Webster defines
mental health as "A state of emotional and psychological well-being in
which an individual is able to use his or her cognitive and emotional
capabilities, function in society, and meet the ordinary demands of everyday
life.
According to the World Health Organization, there is
no one "official" definition of mental health. Cultural differences,
subjective assessments, and competing professional theories all affect how
"mental health" is defined. In general, most experts agree that
"mental health" and "mental illness" are not opposites. In
other words, the absence of a recognized mental disorder is not necessarily an
indicator of mental health.
One way to think about mental
health is by looking at how effectively and successfully a person functions.
Feeling capable and competent; being able to handle normal levels of stress,
maintain satisfying relationships, and lead an independent life; and being able
to "bounce back, or recover from difficult situations, are all signs of
mental health.

Reactance
is the invented part of electrical impedance, a measure of opposition to a
sinusoidal alternating current. Reactance arises from the occurrence of inductance
and capacitance within a circuit, and the SI unit is the ohm. The value of the
reactance is a lower maximum value on the amount of the impedance. A positive
reactance implies that the phase of the voltage leads the phase of the current,
while a harmful reactance implies that the phase of the voltage lags the phase
of the current. A reactance of zero implies the current and voltage are in
phase and equally if the reactance is non-zero then there is a phase
distinction between the voltage and current

The first form of life to develop on the Earth was microbes,
and they remained the only form of life on the planet until about a billion
years ago when multi-cellular organisms began to appear. Microorganisms are
single-celled organisms that are generally smaller than the human eye can see.
They include Bacteria, Fungi, Archaea and Protista.
These
life forms are found in almost every location on the Earth where there is
liquid water, including the interior of rocks within the planet. Their
reproduction is both rapid and profuse. The combination of a high mutation rate
and horizontal gene transfer ability makes them highly adaptable, and able to
survive in new environments, including outer space. They form an essential part
of the planetary ecosystem. However some microorganisms are pathogenic and can
post health risk to other organisms.
