All of Gold Coast City Council’s Tourist Parks have been given the ‘tick of approval’ by the Caravan, RV and Accommodation Industry of Australia, (CRVA).

Chair of Council’s Community and Cultural Development Committee, Cr Bob La Castra, said he was not surprised that Council’s Tourist Parks had received the coveted Tourism Tick.

“We have some of the best Tourist Parks in country and receiving the tick of approval from Australia’s peak body for the caravanning industry confirms this,� said Cr La Castra.

The Tourism Tick is a nationally recognised benchmark of quality tourism performance and is only awarded to Tourism Parks that have completed the CRVA’s National Accreditation program.

“Our Tourist Parks where required to develop quality management systems in the areas such as risk management, environmental management and customer service,� said Cr La Castra.

“By successfully completing the program our Tourist Parks have not only improved their levels of service and management, they have also ensured that these standards continue to improve.�

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

Gold has been recognized and highly-valued since prehistoric times. It might have been the first metal used by humans and was valued for both ornamentation and rituals. Gold is the most malleable and ductile metal; a single gram could be beaten into a sheet of one square meter, or an ounce into 300 square feet. Gold leaf can be flattened thin enough to become translucent. The transmitted light appears greenish blue, as gold strongly reflects yellow and red. It readily forms alloys with many other metals. Gold is an excellent conductor of heat and electricity, and is not affected by air and most reagents. Heat, oxygen, moisture, and most corrosive agents have very little chemical effect on gold, making it very well-suited for use in coins and jewelry. Pure gold is so soft for ordinary use and is hardened by alloying with copper or other base metals. The gold content of gold alloys is measured in carats (k), pure gold being designated as 24k.

Butterflies are adult flying stage of certain insects belonging to an order or group called Lepidoptera. Moths also belong to this group. The word "Lepidoptera" means "scaly wings" in Greek. This name completely suits the insects in this group because their wings are covered with thousands of tiny scales overlapping in rows. The scales, which are arranged in colorful designs unique to every species, are what give the butterfly its beauty. Like all other insects, butterflies also have six legs and three main body parts: head, thorax (chest or mid section) and abdomen (tail end). They also have two antennae and an exoskeleton.

Hurricane Katrina was the one of the five deadliest hurricanes in the history of the United States. It was the sixth-strongest Atlantic hurricane that was ever recorded and the third-strongest hurricane on record that made landfall in the United States. Katrina formed on August 23 during the 2005 Atlantic hurricane season and caused devastation along the north-central Gulf Coast. The most severe loss of life and property damage occurred in New Orleans, Louisiana, which flooded as the levee system catastrophically failed; in many cases hours after the storm had moved inland. In the 2005 Atlantic season, Katrina was the eleventh tropical storm, fifth hurricane, third major hurricane, and second Category 5 hurricane.

An earthquake is caused by sudden, violent shifting of massive rocks called plates lying under the earth's surface. This movement of the plates releases stress that accumulates along geologic faults. A fault is a deep crack that marks the boundary between two of the plates. Earthquake belts occur along faults all around the world. Many run along coastal areas. The San Andreas Fault in central California is well-known for causing most severe earthquakes. The epicenter is the point on the surface where the earthquake is strongest. The Richter scale is used to measure the amount of energy that is released by the earthquake.

An inductor is a passive electrical device working in electrical circuits for its property of inductance. Inductance is an consequence which results from the magnetic field that forms around a current carrying conductor. Electrical current through the conductor creates a magnetic flux relative to the current. A change in this current creates a change in magnetic flux that, in turn, generates an electromotive force that acts to oppose this change in current. Inductance is a calculate of the generated emf for a unit modify in current. An inductor with an inductance of 1 henry produces an emf of 1 V when the current through the inductor changes at the rate of 1 ampere per second. The number of turns, the area of each loop/turn, and what it is wrapped around influence the inductance.

Polyester is the most widely used manufactured fiber in the United States. Natural fiber polyester fabrics are used for attire and home furnishings. These include bed sheets, bedspreads, curtains and draperies. Polyester fiberfill is also used to substance pillows, comforters and cushion stuffing.

Polyester fabrics sometimes have a "less natural" feel when compared to correspondingly woven fabrics made from ordinary fibers, e.g., cotton. However, polyester fabrics may demonstrate other advantages over natural fabrics, e.g., improved wrinkle confrontation. As a result, polyester fibers are often spun mutually with natural fibers, e.g., cotton, to create a cloth with blended properties.

Polyesters are also used to make bottles, films, oilcloth, liquid crystal displays, holograms, filters, dielectric film for capacitors, film insulation for wire and insulating tapes. Liquid crystalline polyesters are among the first scientifically used liquid crystalline polymers. In general they have extremely good perfunctory properties and are exceptionally heat defiant. For that reason, they can be used as an abradable seal in jet engines.

Thermosetting polyester resins are normally copolymers of unsaturated polyesters with styrene. The unsaturation in the polyester is generally governed by maleic acid or fumaric acid. Another important family is the group of vinyl esters. Here the unsaturation is found in the alcohol part of the polyester. The double bond of the unsaturated polyester reacts with styrene resulting in a 3-D crosslinked structure, the thermoset fabric. The cross-linking is initiated through an exothermic reaction involving an organic peroxide, such as methyl ethyl ketone peroxide or benzoyl peroxide. Unsaturated polyesters are commonly used as casting materials, fiberglass laminating resins, and non-metallic auto-body fillers. Fiberglass reinforced unsaturated polyesters find wide application in bodies of yachts and as body parts of cars.

Temperature is a physical assets of a system that underlies the common notions of hot and cold; something that is hotter generally has the greater temperature. Specifically, temperature is a property of substance. Temperature is one of the major parameters of thermodynamics. On the microscopic scale, temperature is defined as the average energy of microscopic motions of a single atom in the system per degree of freedom. On the macroscopic scale, temperature is the exclusive physical property that determines the direction of heat flow between two objects placed in thermal contact. If no heat flow occurs, the two objects have the same temperature; otherwise heat flows from the hotter object to the colder object. These two basic principles are stated in the zeroth law and second law of thermodynamics, respectively. For a solid, these microscopic motions are principally the vibrations of its atoms about their sites in the firm. For an idyllic monatomic gas, the microscopic motions are the translational motions of the component gas particles.

Temperature is measured with thermometers that may be calibrated to a range of temperature scales. In most of the world (except for the United States, Jamaica, and a few other countries), the degree Celsius scale is used for most warmth measuring purposes. The entire scientific world  measures temperature using the Celsius scale and thermodynamic temperature using the kelvin scale, which is just the Celsius scale shifted downwards so that 0 K[1]= −273.15 °C, or absolute zero. Many engineering fields in the U.S., especially high-tech ones, also use the kelvin and degrees Celsius scales. However, the United States is the last major country in which the degree Fahrenheit temperature scale is used by most lay people, industry, popular meteorology, and government. Other engineering fields in the U.S. also rely upon the Rankine scale  when working in thermodynamic-related disciplines such as incineration.
