CCTV, Initially to Rocket Monitor

First CCTV (Closed-circuit television) system was installed by Siemens AG at Test Stand VII in Peenemunde, Germany in 1942. This CCTV system used to observe the launch of the world's first ballistic missile Vergeltungswaffe-2 (V-2).

German engineer Walter Bruch was responsible for the design and installation of these systems. With CCTV, officers were able to monitor the test from short range without danger, watching the damage and other problems that may have otherwise gone undetected.

In the U.S. the first commercial closed-circuit television system became available in 1949, called Vericon. Very little is known about Vericon except it was advertised as not requiring a government permit.

CCTV recording systems are still often used at modern launch sites to record the flight of the rocket, find possible causes of the failure of the work function. Larger rockets fitted CCTV allowing pictures of stage separation to be transmitted back to earth via radio communication.

In September 1968, Olean, New York was the first city in the United States who use a video camera in the business world, especially in an effort to prevent crime. CCTV connected to the monitor in the Olean PD. Police Department became the frontline in the fight against crime using CCTV technology.

Currently, the use of CCTV cameras in public spaces to minimize the risk of crime. CCTV cameras cover most of the urban areas. CCTV installed at every street corner to make it easy to police monitor the point where are experiencing congestion or crime, so that treatment can be carried out immediately.

The use of CCTV cameras is not limited to the public sphere alone but has been widely used by individual persons or companies for a variety of purposes. *** [WIKIPEDIA | SEPTI | PIKIRAN RAKYAT 27092012]

Fire tornado as high as 30 meters that recorded a video camera Chris Tangey of Alice Springs Television on 16 September 2012 is a rare phenomenon. Incidentally, Tangey, which is conducting the survey location near Curtin Springs in Australia, saw a vortex of fire that rose high into the sky.

"Tornado sounded like a jet fighter aircraft that pass, but there's no wind around Us," said Tangey told the Northern Territory News.

The fire tower was dancing on the landscape for nearly 40 minutes. Tangey and his team from the TV station motionless witness the rare natural events. Although rare, a fire tornado also occurred in several other regions of the world, including in Aracatuba city, Brazil. Drought experienced during the three months the city created the perfect conditions for the fire tornado.

This rare event occurs when the fire stirred by a strong flow of dry air to form a vertical vortex. Tornadoes can form a vortex of hot air around or in the pillar of fire.

The phenomenon is often dubbed as the fire demon can be revoked as high as 15 feet up a tree root. Generally, tornado of flames reaching 30-50 meters tall with a diameter of several meters and lasted a few minutes. But the huge fire tornado can reach hundreds of meters with winds of 160 kilometers per hour. Tornadoes of this magnitude can take more than 20 minutes.

Most tornadoes form when the fire fire fire met with warm air moves upward. Large fires can create a vortex of fire the size, intensity, and duration were varied.

In 1923, the Great Kanto earthquake in Japan triggered a storm of fire and a city-wide fire vortex generating enormous. Within 15 minutes the giant fire tornado that killed 38 thousand people. *** [REUTERS | LIVESCIENCE | KORAN TEMPO 4005]

Know the Seismic Waves

Earthquake is a jolt in the earth's crust as a companion symptom of tectonic, volcanism activity, or debris that occurs in the earth. At the time of the earthquake, we can feel the vibrations or shocks on where we stand. Earth rocked sideways and upwards. Vibration or shock is seismic waves.

Seismic waves are very low frequency waves that spread through the earth. The emergence of the seismic waves caused by a shift in the Earth's crust segments or can be generated from the explosion at the top of the crust.

The rate of amplitude and direction of propagation of seismic waves depends on the type of seismic waves and the material in its path. Seismograph record the amplitude and frequency of seismic waves and generate information about the earth and the subsurface structure of the earth.

Types of seismic wave. (Picture from: http://www.physics.unc.edu/)

Seismic waves generated naturally as a result of shifting crust (plates) of the earth to the attention of seismologists (seismologists) and physicists to determine the center of the earth quake. While the seismic waves generated artificially as a result of an accidental explosion on the upper crust of the earth useful to geologists and physicists to study the state of the earth of the earth and help search for the sources of fossil fuels.

Seismic waves are divided into two types. First, body wave. Body wave consists of primary wave (commonly abbreviated as P waves) and secondary waves (commonly abbreviated as S waves). Body wave propagates through the earth outwards from the epicenter.

P waves typically arrive at the surface of the earth as a jolt. P waves move faster than S waves, so the P wave is the first wave recorded on seismographs (earthquake recording devices) and became the first wave of people in the area felt the quake. Because it is the first, the wave is called the primary wave.

Seismic wave mapping of the interior of the Earth. (Picture from: http://www.physics.unc.edu/)

P waves (also called compressional or longitudinal waves) travels through solids, liquids (liquid). and gas, and thus going through the whole body of the earth. P waves cause the transmission medium is a liquid, solid, or gas moving back and forth in the direction of the path of deployment. When P waves traveling through rock, the waves move / push tiny rock particles back and forth in the direction of wave propagation. The result is a series of strain and pressure back and forth. This incident is similar to what happens when we pull or a slinky stretch horizontally.

In the earth, the P wave propagates at a rate of about 6 kilometers (3.7 miles) per second at the surface of the rock to about 10.4 kilometers (6.5 miles) per second near the earth's core (approximately 2,900 kilometers below the Earth's surface ). Accretion rate of the P wave to the depths of the earth due to increase hydrostatic pressure, which corresponds to changes in the composition of the rocks. In general, the accretion rate resulting P wave propagates with a curved path.

Seismic waves (Earthquakes) probe the interior of the Earth. (Picture from: http://www.physics.unc.edu/)

The appearance of the P wave was accompanied by a wave of S. S waves are also known as shear or transverse waves. The rate of propagation of the S wave and P wave arrival time resulted in two distinct waves separated when detected by seismographs. Separate arrival times can be used to determine the location of the epicenter.

S waves are transverse shear wave like a wave on the pull rope. Material moves up and down or from side to side. Like the P waves, S waves also spread to the curved trajectory.

S waves can only be spread through a solid medium for liquid and gaseous medium can not sustain shear stress. In the earth, the rate of increase of the S wave about 3.4 kilometers (2.1 miles) per second at the earth's surface up to 7.2 kilometers (4.5 miles) per second near the limit of the earth's core. S waves cause the dots on solid medium moves back and forth perpendicular to the direction of the spread of the wave. When the S waves move, these waves move rock particles outward and push the particles perpendicular to the wave trajectory. It results in the first period roling associated with earthquakes.

The second type of seismic waves are surface waves. Surface waves sometimes resemble waves in the water that moves up and down the earth's surface.

Animation of seismic waves. (Picture from: http://earthquake.usgs.gov/)

This animation shows the seismic waves generated by the 2002 Denali Fault earthquake. P-waves are shown in red; S-waves are shown in blue; Surface waves are shown in yellow. Phase arrival times are indicated on the vertical (Z) seismograms displayed at the top of the animation.

SSPA: Standing Stone, Pennsylvania
CTAO: Charter Towers, Australia
DBIC: Dimbokro, Cote d'Ivoire
LBTB: Lobatse, Botswana

This animation is running 100 times faster than the waves actually traveled. Animation of PC program Seismic Waves written by Alan Jones.

Surface wave propagates in the Earth's surface at a rate of approximately 3.5 to 3.9 kilometers per second and slower than body waves. Because the surface wave has a low frequency, long duration of propagation, the width and amplitude of the surface wave is a kind of the most destructive seismic waves. Surface waves move the rock on man-made structures of the building foundation.

Surface wave consists of Rayleigh waves and Love waves. Rayleigh waves are surface waves similar to the rise and deployment of water surface waves. The existence of these waves was predicted long ago by a British physicist Lord Rayleigh in 1885. He was the first to express mathematically the existence of these waves.

Rayleigh waves traveling through the free surface in the form of elastic solids in the earth. The movement of these waves is a combination of longitudinal compression and dilation which then produce an elliptical motion at points on the surface of the earth. In all seismic waves, Rayleigh waves most often (all the time) to spread out and produce a long-duration waves on a seismograph.

Meanwhile, Love waves are surface waves that cause horizontal shifting of the earth surface. The word "Love" is used in the name of the wave is taken from the name of AEH Love. He was a British seismologists who first predicted the existence of these waves and mathematical modeling in 1911.

Love waves are usually spread a little faster than the Rayleigh wave. Love waves spread when a solid medium near the Earth's surface has a vertical elastic properties are diverse. Medium shift entirely by Love waves perpendicular to the direction of the spread of the wave. Energy deployment Love waves produce strong record on seismic stations. *** [GUN GUN GUNAWAN | PIKIRAN RAKYAT 13092012]

Ozone and Life on Earth

Ozone (O3) is a molecule composed and bonded of three oxygen atoms. Bonds between the oxygen atoms in the ozone molecule is rather weak compared to the oxygen molecule consists of two atoms (O2), so one of the three oxygen atoms easily escape and react with other molecules.

Ozone was first discovered by Christian Friedrich Schonbein in 1840. Naming ozone is derived from the Greek, ozein meaning smell. Ozone is known as a gas that has no color.

The use of ozone has been performed for more than a century ago. Ozone is used for various purposes, ranging from clean drinking water, sterilization of raw food materials, to elaborate a variety of toxic organic compounds contained in wastewater. In the field of medicine, ozone is more often used after the discovery of the ozone producing equipment for medical sterilization by J Hansler in the mid-20th century. However, ozone is a toxic substance. This gas is very reactive and corrosive (rapidly cause corrosion on metal) and hazardous to human health if inhaled in large quantities.

Ozone is found naturally in the stratosphere. Approximately ninety percent of Earth's ozone is in the stratosphere. Stratosphere is one of the layers of the earth's atmosphere at an altitude between 20-50 kilometers above the earth's surface. The ozone layer in the stratosphere was first discovered in 1913 by Charles Fabry (1867-1945) and Henri Buisson.

The ozone layer in the stratosphere naturally formed mainly through a process fotodisosiasi where the sun has a very important role in this process. Ultraviolet rays emitted by the sun was able to break an oxygen molecule (O2) to form two single oxygen atom. Then every single oxygen atom is bonded to an oxygen molecule to form a molecule of ozone (O3).

Diagram illustrating the ozone-oxygen cycle. (Picture from: http://commons.wikimedia.org/)

The presence of beneficial ozone in the stratosphere protects the earth from the dangers of ultraviolet emission (UV) excessive sun. This ozone protects life on earth by absorbing harmful ultraviolet radiation from the sun. Because it is protecting the ozone in the stratosphere that is also called good ozone.

Ozone in the stratosphere absorbs ultraviolet radiation emitted by the sun. This radiation has a wavelength below 400 nanometers. The spectrum of this radiation (located at wavelengths between 290 nanometers and 320 nanometers) or better known as UV-B radiation. Increasing doses of UV-B radiation reaching the earth resulting in increased cases of skin cancer, lower yields, and ruin the lives of plankton and fish larvae.

Reaction formation and decomposition of ozone occurs naturally in a state of balance and continuously for centuries. Most of the ozone is formed and decomposes in the equatorial region where there are tropical rainforests were quite extensive. By nature, nature has arranged transport phenomena that will bring the gases contained in the earth's surface to the layer above it and distribute ozone into the higher latitudes, and eventually accumulates in the polar regions.

The process of ozone depletion. (Picture from: http://sopf.org/)

However, the balance of the formation and decomposition of ozone has been disrupted due to the increase of ozone-depleting substances or materials (ozone depleting substances / ODS), so the rate of decomposition of ozone faster than the rate of its formation. Damaging substances / thinning of the ozone layer in the lower stratosphere is produced by human activities on the earth's surface. These substances are capable of spreading to the stratosphere. This causes a decrease in the concentration of ozone in the stratosphere.

Ozone depleting substances contain some combination of chemical elements chlorine, fluorine, bromine, carbon, and hydrogen are called halozarbon. The compound consists of only chlorine, fluorine and carbon called cholorofluorocarbon (CFC). CFCs are widely used because it is stable with low toxicity and non-flammable. Because CFCs have chemical and physical properties suitable for coolant, solvents, and heat insulation, this material is widely used by industrial refrigerator, AC (air conditioner), gas booster (spray), foam plastic, fire extinguisher material, the solvent in the industry, and electronic equipments cleaning. If this material is released into the atmosphere by atmospheric transport phenomena, these materials will be lifted and diffused into the stratosphere. In this layer the material will be dissociated by ultraviolet radiation from the sun and breaks down into chlorine gas was very active damaging the ozone layer.

The climate system is complex, meaning that the ozone hole does indirectly alter the surface temperature and climate of the Earth. (Picture from: http://theconversation.edu.au/)

The monitoring of the ozone layer in the stratosphere has long made the developed countries since 1957. In 1985, researchers from the UK found a reduction in the total amount of ozone in the stratosphere during the Antarctic spring. In 1987, a monitoring station in Antarctica recorded a decrease in the total amount of ozone to be less than half the amount of ozone measured in 1970. This drastic decrease in ozone depletion has caused or is called the ozone hole (ozone hole).

Global emissions of ozone-depleting chemicals (CFCs, halons, HCFCs, and others) and their non-ozone depleting substitutes (HFCs) from 1950 to 2050, expressed as Gigatonnes of CO2-equivalent per year. The blue hatched regions indicate the emissions that would have occurred, in the absence of the Montreal Protocol, with 2–3% annual production increases in all ozone-depleting chemicals. Shown for reference are emissions for the range of CO2 scenarios from the IPCC Special Report on Emission Scenarios. (Picture from: http://theconversation.edu.au/)

The discovery of the ozone hole has prompted the formulation of an international treaty known as the Vienna Convention 1985. The agreement aims to protect the environment and human health due to the depletion of the ozone layer. Then in 1987 established the Montreal Protocol. In the protocol was approved reduction and elimination of the production and consumption of CFCs, halon, and other similar substances that contribute to depleting the ozone layer. *** [THE CONVERSATION | SAVE OUR PLANET FOUNDATION | DEDE NURROSYID | PIKIRAN RAKYAT 13092012]

QR Memories, Barcodes for Headstones

Barcode technology is usually used in supermarkets to determine the type and price of the goods to be purchased. However, the current barcode technology is not only used in the supermarket, at the funeral QR technology also can be applied.

The modern cemetery Chester Pearce, in Poole, Dorset, England applying barcode technology on a headstone. Barcode is located at the corner of the bottom of the headstone.

As quoted from Daily Mail, the application of technology to the headstone was intended to ascertain data on the deceased. Family left behind do not bother to write the date of birth or date of death on the headstone. All the detailed information on the profile of the deceased can be seen simply by scanning using a smartphone.

The barcode technology is called a QR memories. Not only the profiles, the family can also see a collection of photos and video of the deceased, in his lifetime. But of course the family are updating this information.

The Chester Pearce funeral director, Stephen Nimmo says the idea of ​​using these technologies is to provide services that can be used to help those left behind. Families do not need to wonder about who is buried there. By using a QR code they can easily find out all he wanted to know.

Scanning the QR code brings up the biography of the deceased. (Picture from: http://www.kiwilstudio.com/)

Even so, of course, required additional charges are not cheap to get these advanced features. Users are charged 300 pounds (U.S. $ 484 or Rp. 4.6 million) for the installation of QR code and additional cost 95 pounds (U.S. $ 147 or Rp. 1.4 million) to hire a website hosting. *** [GI | DAILY MAIL | PIKIRAN RAKYAT 13092012]

Maternal Genes Found in Mice

Maternal feelings shown holding her son apparently formed by a gene. Researchers from Rockefeller University in New York, USA, have discovered the existence of genes that are responsible for feelings of maternal rats.

Mouse in a laboratory. (Picture from: http://www.telegraph.co.uk/)

They found that mice engineered to suppress the expression "maternal gene" spend a little time to lick, feeding, and cleaning up their child. These conditions contrast with the rats from the control group who care for her child.

"There is a single gene responsible for motivating the parent to protect, feed, and raise their children," said study leader, Ana Ribiero, in findings published in the Proceedings of the National Academy of Sciences on Wednesday September 19, 2012.

Previous research shows that there are regions in the rat brain called the medial preoptic, in charge of controlling aggression, sexual acceptance and care by the parent. However, what about the chemical mechanisms that affect the behavior, it is yet unclear.

Ribiero says, citing previous research, the nerve cells respond to estrogen, a female sex hormone-containing receptor alpha and estrogen in high levels. These chemicals are linked to the behavior of rat maternal care and sexual behavior.

"We lowered the level of the receptor in the medial preoptic female rats to examine the response of those without it," he said, as quoted by the Telegraph. The research team conducted experiments based on this fact.

As a result, mice with low levels of receptors in the brain to spend less time caring for their children. However, it did not affect the aggressiveness.

According Ribiero, manipulation of specific genes in specific nerve cell groups can drastically alter the expression of important biological behavior. *** [TELEGRAPH | MAHARDIKA SATRIA HADI | KORAN TEMPO 4002]
