INDIAN STANDARD TIME AND ATOMIC CLOCKS

India is planning to legalise Indian Standard Time

Microsoft software or iPhone users get the

time sourced from US-based Network Time Protocol. Once IST becomes legal, users will not be allowed to

use any other time other than the one generated by National Physical Laboratory

 

 

 

 

ü Other elements used to make atomic clocks are:

o Rubidium (Lower cost but less stable),

o Hydrogen masers (short-term stability and low long-term accuracy),

o Mercury ions,

o Isotope of Ytterbium and Strontium

Who maintains Indian Standard Time?

ü National Physical Laboratory in Delhi, also known as National Measurement Institute

ü The Time and Frequency Standards Laboratory at the institute in New Delhi generate official time signals for both commercial and official use.

ü The signals, based on atomic clocks, synchronize with the worldwide system of clocks that support the Coordinated Universal Time.

 

Atomic Clocks

üa kind of clock that uses an atomic resonance frequency standard

übased on the properties of atoms transitioning between different energy states.

ü The oscillation frequencies within the atom depend on the mass of the nucleus and the gravity and

electrostatic “spring” between the positive charge on the nucleus and the electron cloud around it.

ü The most accurate atomic clocks available today use the cesium atom and normal magnetic fields and detectors.

ü Cesium 133

ü Inside a cesium atomic clock, cesium atoms are funneled down a tube where they pass through radio waves. When these atoms at resonate frequency, they change their energy state.

.Indian Standard Time

ücalculates on the basis of 82.5° E longitude, just west of the town of Mirzapur, near Allahabad in the state of Uttar Pradesh.

 longitude difference between Mirzapur and the United Kingdom’s Royal Observatory at Greenwich:exact time difference of 5 hours 30 minutes.

ü earliest descriptions of standard time in India , fourth century C.E.

astronomical treatise Surya Siddhanta. Postulating a spherical earth, the book defined the primemeridian, or zero longitude, as passing through Avanti (Ujjain) and Rohtak.

ü India standard Meridian passes through Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Odisha and Andhra Pradesh.

CALL FOR TWO TIME ZONES IN INDIA Council of Scientific & Industrial Research’s National Physical Laboratory (CSIR-NPL), which maintains Indian Standard Time (IST), has published a research article describing the necessity of two time zones • In 2006, the Planning Commission recommended the introduction of two time zones in the country, saying it would save “a lot of energy”.
POLIO VIRUS
BOMBALI VIRUS STRAIN AND EBOLA Researchers discovered a new strain of Ebola Virus In bats in northern Bombali region of Sierra Leone.

ü The newly discovered strain has been named as Bombali virus strain, after district where it was found.

ü The Bombali virus is overall sixth known virus strain Ebola virus. Others are:

1. Zaire,

2. Sudan,

3. Tai Forest,

4. Bundibugyo and

5. Reston.

What is Ebola?

ü Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness

in humans.

ü The virus is transmitted to people from wild animals and spreads in the human population through

human-to-human transmission.

ü The average EVD case fatality rate is around 50%. Case fatality rates have varied from 25% to 90% in

past outbreaks.

ü It was first described in the 1940s by Viennese pediatrician Hans Asperger, who observed autism like

behaviors and difficulties with social and communication skills in boys who had normal

 

developmental disorder characterized by significant difficulties in social

interaction and nonverbal communication, along with restricted and repetitive patterns of behavior

and interests.

intelligence and language development.

ü Children with Asperger’s Disorder may be only mildly affected, and they frequently have good language

and cognitive skills. limited or inappropriate social interactions

o “robotic” or repetitive speech

o challenges with nonverbal communication (gestures, facial expression, etc.) coupled with

average to above average verbal skills

o tendency to discuss self rather than others

o inability to understand social/emotional issues or nonliteral phrases

o lack of eye contact or reciprocal conversation

o obsession with specific, often unusual, topics

o one-sided conversations

o awkward movements and/or mannerisms

NOROVIRUS

no vaccine is available against the Virus

ü symptoms of norovirus :o Nauseao Vomiting

o Abdominal pain or crampso Watery or loose diarrhoeao Low-grade fever

very contagious virus that can infect anyone.

ü one of the most common stomach bugs in the UK.

ü called the winter vomiting bug because it’s more common in winter, although one can catch it at any time of the year.

ü spread by the faecal–oral route.

ü may be by contaminated food or water or person-to-person contact.

ü may also spread via contaminated surfaces or through the air.

ü Risk factors include unsanitary food preparation.

ü Disinfecting the surfaces are the ways to prevent it.

It is associated with intellectual and learning disabilities.

ü Persons with Down Syndrome have 47 chromosomes

slows down learning process impacts neurological functioning causing impairment of intellectual functions e.g. analytical thinking,

complex abstractions and judgement etc.

Huntington Disease

ü Huntington’s disease (HD) is a fatal genetic disorder that causes the progressive breakdown of nerve cells in the brain

ü HD is known as the quintessential family disease because every child of a parent with HD has a 50/50 chance of carrying the faulty gene.

ü It deteriorates a person’s physical and mental abilities during their prime working years and has no cure.

ü Symptoms usually appear between the ages of 30 to 50, and worsen over a 10 to 25 year period.

ü Ultimately, the weakened individual succumbs to pneumonia, heart failure or other complications.

ü Everyone has the gene that causes HD, but only those that inherit the expansion of the gene will develop

HD and perhaps pass it on to each of their children.

ü Every person who inherits the expanded HD gene will eventually develop the disease.

ü Over time, HD affects the individual’s ability to reason, walk and speak

GENETIC DISORDERS genetic disorder is a disease caused by abnormalities or mutations in the DNA sequence

 

by damage to chromosomes- Down Syndrome

by a single error in a single gene in the human DNA. (such as Sickle cell disease and cystic fibrosis )

QUADRIVALENT INFLUENZA VACCINE he quadrivalent vaccine will contain four influenza virus strains (two A subtypes and two B subtypes — H1N1 and H3N2, and Victoria and Yamagata respectively).

Influenza, or flu, is a respiratory illness caused by a virus

Types of influenza viruses

ü There are four types of influenza viruses: types A, B, C and D:

o Influenza A viruses: infect humans and many different animals. It can cause an influenza

pandemic.

o Influenza B viruses: circulates among humans and cause seasonal epidemics. Recent data

showed seals also can be infected.

o Influenza C viruses: can infect both humans and pigs but infections are generally mild and

are rarely reported.

o Influenza D viruses: primarily affect cattle and are not known to infect or cause illness in

people.

What is H and N that we Influenza type A viruses are classified into subtypes according to the combinations of different virus

surface proteins hemagglutinin (HA) and neuraminidase (NA). So far there are 18 different hemagglutinin

subtypes and 11 different neuraminidase subtypes.

ü Depending on the origin host, influenza A viruses can be classified as avian influenza, swine influenza,

or other types of animal influenza viruses.

ü Examples include avian influenza “bird flu” virus subtypes A(H5N1) and A(H9N2) or swine influenza”swine flu” virus subtypes A(H1N1) and A(H3N2).

Earth and Mars used to be similar – warm, wet and shrouded in thick atmospheres.

• But this was before they took different paths 3.4 billion years ago.

• After the event, Mars stopped changing, while Earth continued to evolve.

• They turned out so different – Mars cold and dry, Venus and Mercury burning hot, and Earth hospitable to life.

• With InSight, Earth would thus be compared to Mars, to better understand how a planet’s starting materials make it more or less likely to support life.

• It is thus expected to study how Mars and other rocky worlds formed at the dawn of the solar system 4.6bn years ago.

• But notably, sending a probe to Mars, whether to land, orbit or fly past, is risky; only 40% of missions have succeeded so far. Landing site – The landing site is Elysium Planitia, where InSight can stay still and quiet all through.

EU Ruling on Gene Editing

guidelines on genetically modified organisms (GMOs) will apply to plants bred using gene editing

technology (mutagenesis

gene editing?

·  Genetic modification involves the introduction of foreign DNA into an organism.

·  On the other hand, gene editing involves editing of the organism‟s native genome.

·  CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a gene editing technology.

·  CRISPR was talked about recently for its successful use in human embryos.

·  This is done by introducing a protein (Cas9) containing the code of a defective gene.

·  The protein then seeks out parts of the defective DNA that match this code.

·  It then attaches itself to it, cuts it out, and then the DNA is allowed to repair itself by getting rid of the defect

Oumuamua Comet Discovery

”, was first spotted on October, 2017.

 

Oumuamua – Hawaiian for “a messenger from afar arriving first”

·  When it was discovered, the oddly-shaped, about 800-m

·  It was dark and faint, with no visible „coma‟ (atmosphere of dust and gas around a comet‟score) or „tail‟ (elongated cloud that points away from the Sun) signature identifiers of comets as they approach the inner Solar System

 

Oumuamua differs from other comets?

·  The dust grains have to be larger than typical for other Comets, which could be a reason for the absence of the characteristic cometary tail.

·  The tail we see in comets is typically made of fine dust lifted off the nucleus and dragged away by the emitted gas.

·  In the case of „Oumuamua, the dust is not visible because it‟s made of larger grains, that are too heavy to be lifted off by the gas.

·  The gas itself is actually very difficult to detect, because the specific molecules composing it (water, CO and CO2) are difficult to see in optical images

OPTICALLY STIMULATED LUMINESCENCE Two forms of luminescence dating:

Thermally stimulated luminescence (TSL) and optically stimulated luminescence (OSL)

ü TSL measures energy emitted after an object has been exposed to temperatures between 400 and 500°C;

ü OSL measures energy emitted after an object has been exposed to daylight

 

Luminescence dating is based on the principle that certain naturally occurring minerals (e.g. quartz, feldspar), which are previously exposed to ionizing radiation, will emit light (luminescence) when they radio

are thermally or optically stimulated

RADIO WAVE TECHNOLOGY

The National Physical Laboratory has signed an agreement with IFR Information Dissemination Services

(IFR) Ltd. to set up the towers and employ long wave radio (LWR) technology for disseminating Indian

Standard Time

ü According to NASA, wavelength: 1 mm to 100 km.

Frequencies range :3,000 cycles per second

ü communications signals travel through the air in a straight line, reflect off of clouds

or layers of the ionosphere, or are relayed by satellites in space.

ü used in standard broadcast radio and television, shortwave radio, navigation and airtraffic

control, cellular telephony, and even remote-controlled toys.

Advantage of Long Wave Radio Wave in time dissemination

ü travel close to the ground and so can reach out to far-flung locations, even to submarines

SONAR TECHNOLOGY ü basic remote sensing technology.

ü Sonar stands for Sound Navigation and ranging and it developed for submarine warfare in World War I.

ü transmits sound waves that are then returned in form of echoes which are used to analyze various qualities or attributes of the target or object.

ü works excellently in water, where sound travels far better than light or radio waves

ü Sonar sensors are in active use on cars today, primarily in the form of parking sensors. These shortrange(~5m) sensors enable a cheap way to know just how far that wall is behind your car.

ü Sonar hasn’t been proven to work at the kinds of ranges a self-driving car demands (60m+).

Developments in autonomous technologies

RADAR technology is not affected by adverse weather conditions such as clouds, rainfall or fogs.

LiDAR pulses are adversely affected by atmospheric weather conditions such as dense fogs, smoke and even rain.

 

The most widespread RADAR usage is for military purposes. Airplanes, weather

forecasting, etc.

Ground-penetrating RADAR is used in geology to determine the composition of Earth’s crust

It is mainly used in mapping archeological sites, for urban planning, crop management, etc.

It is also used in atmospheric sciences (to measure atmospheric densities of various components such as aerosols and other atmospheric gases).

 

Two of the most talked about self-driving advancements come from Google and Tesla(Waymo and Autopilot).

 

Waymo: Google’s autonomous car development company. It stands for a new ‘way forward in mobility’.

Autopilot: It is Tesla’s semi-autonomous driving technology

 

Tesla uses Camera and Radar technology while

Google’s WAymo uses LIDAR-based system.

 

Tesla is presently focusing on driver assisted cars while

Waymo’s focus is to develop completely autonomous cars.

Some of the other technologies used:

Radar LIDAR

Radio Detection And Ranging Light Detection and Ranging

RAMA (RECONSTITUTING ASTEROIDS INTO MECHANICAL AUTOMATA)- NASA has recently announced it would give funds to a California-based 3D printing company for finding

ways to turn asteroids into giant, autonomous spacecrafts, which could fly to outposts in space

 

ü The objective of this study is for Made In Space (MIS) to establish the concept feasibility of using the age-old technique of analog computers and mechanisms to convert entire asteroids into enormous autonomous mechanical spacecraft.

ü The company plans to use 3D printing to turn the asteroids into self-flying vehicles by 2030

ü The concept received funding through NASA’s Innovative Advanced Concepts programme, which will provide $100,000 for feasibility studies

 

Mechanism

ü The company is considering sending an advanced robotic “Seed Craft” out to rendezvous with a succession of near-Earth asteroids in space, as part of its long-term project.

ü The Seed Craft would harvest material from the space rocks, then use this feedstock to construct propulsion, navigation, energy-storage and other key systems onsite with the aid of 3D printing

ü Thus transformed into autonomous spacecraft, the asteroids could be programmed to fly to a mining

station in Earth-moon space, or anywhere else they’re needed.

ü This approach would be much more efficient than launching a new capture probe (or probes) to

every single space rock targeted for resource exploitation

BIO PLASTIC- plastics derived from renewable biomass sources, such as vegetable fats and oils, corn

starch, or microbiota

ü The disease mainly affects the skin, the peripheral nerves, mucosal surfaces of the upper respiratory

tract and the eyes.

 

ü Leprosy is known to occur at all ages ranging from early infancy to very old age.

ü It is curable and early treatment averts most disabilities.

ü The exact mechanism of transmission of leprosy is not known.

ü Contrary to popular belief, it is not highly contagious

ü Signs of leprosy are painless ulcers, skin lesions of hypopigmented macules (flat, pale areas of skin), and eye damage (dryness, reduced blinking).

ü Later, large ulcerations, loss of digits, skin nodules, and facial disfigurement may develop

IMMUNOTHERAPY also called biologic therapy, is a

type of cancer treatment that boosts the body’s natural defenses to fight cancer

ü uses substances made by the body or in a laboratory to improve or restore immune system function.

 

ü Immunotherapy may work by:

o Stopping or slowing the growth of cancer cells

o Stopping cancer from spreading to other parts of the body

o Helping the immune system work better at destroying cancer cells

ü body’s natural defences — immune cells, also known as T-cells — to detect and kill cancer cells, which otherwise can adapt and hide.

 

 

 

Main types of immunotherapy

ü Monoclonal antibodies: man-made versions of immune system proteins. Antibodies can be very useful in treating cancer because they can be designed to attack a very specific part of a cancer cell.

ü Immune checkpoint inhibitors: drugs basically take the ‘brakes’ off the immune system,  helps it recognize and attack cancer cells.

ü Cancer vaccines: Vaccines are substances put into the body to start an immune response against certain diseases

PROGERIA

extremely rare autosomal dominant genetic disorder

symptoms resembling aspects of aging are manifested at a very early age

Most children with progeria have a mutation on the gene that encodes for lamin A, a protein that holds the nucleus of the cell together. This protein is also known as progerin

ü Children with progeria appear healthy, but by the age of 2 years, they look as if they have become old too fast.

ü  extremely rare, affecting 1 in every 4 million children.

ü  lead to fatal heart complications and a heightened risk of stroke.

ü Progeria is incurable, but symptoms can be managed.

ü Recent findings show that administering a small molecule, named remodelin, reversed these abnormalities in cells isolated from progeria patients

was given a boost, when the 64-dish MeerKAT radio telescope was inaugurated in the remote South

African town of Carnarvon.

ü MeerKAT is a follow up to the KAT 7 (Karoo Array Telescope), built in the vast semi-desert Karoo

region north of Cape Town to demonstrate South Africa’s ability to host the SKA. (“meer” means “more”)

ü Organizations from ten countries are members of the SKA Organisation – Australia, Canada, China, India, Italy, New Zealand, South Africa, Sweden, The Netherlands and the United Kingdom

originally the Karoo Array Telescope, is a radio telescope consisting of 64 mirrors now being

tested and verified in the Northern Cape of South Africa.

ü Built at a cost of 4.4 billion rand, MeerKAT will be incorporated into the complex Square Kilometre Array (SKA) instrument, which when fully operational in the late 2020s would be the world’s biggest

and most powerful radio telescope.

ü The SKA will eventually use thousands of dishes and up to a million low-frequency antennas enable astronomers to monitor the sky in unprecedented detail and survey the entire sky much faster than any system currently in existence.

ü Its unique configuration will give the SKA unrivalled scope in observations, largely exceeding the image resolution quality of the Hubble Space Telescope.

 

CNG AND HYDROGEN-CNG

ü CNG is compressed natural gas.

ü With natural gas mainly composed of methane, CNG emits less air pollutants — carbon dioxide, carbon

monoxide, nitrogen oxides and particulate matter — than petrol or diesel

What is H-CNG?

ü H-CNG is a blend of hydrogen and CNG, the ideal hydrogen concentration being 18%.

ü Compared to conventional CNG, use of H-CNG can reduce emission of carbon monoxide up to 70%,

ü Some minor engine optimisation is needed to make existing CNG buses H-CNG-ready as it will involve “high temperature combustion

GRAVITATIONAL RED SHIFT

to tell the distance of any object that is very far away in the Universe.

ü The red shift is one example of the Doppler Effect.

ü An object, like a star or a galaxy that is far away and moving toward us, will look more blue than it

normally does. This is called blue shift.

ü A star or galaxy moving away from us will look redder than it would if the source were not moving in our

frame of reference. This is where red shift got its name, since the colors are shifted towards the red end

of the spectrum.

 

What is Gravitational Lensing?

ü Gravitational lensing is the process by which light

travelling from a distant source seems to “bend” or

curve around extremely dense objects that lie

between the light source and the observer.

ü It can create the appearance of two or more objects

where there is really only one.

ü This effect is usually observed around large objects, such

as a galaxy or black hole, which creates a very strong

gravitational field in space.

ü The existence of gravitational lenses was predicted by Alfred Einstein in his general theory of relativity

RFID?

ü  technology to record the presence of an object using radio signals.

ü  small transponders (combined radio receiver and transmitter) that will transmit identity information over a short distance, when asked.

ü  an RFID tag reader.

ü An RFID tag can be applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves.

ü Most RFID tags contain at least two parts:

o One is an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions.

o The second is an antenna for receiving and transmitting the signal.

ü There are generally two types of RFID tags:

o active RFID tags, which contain a battery, and

o passive RFID tags, which have no batteries

SUPERCONDUCTIVITY AND MEISNER EFFECT

material is said to exhibit superconductivity when it is able to conduct electric current with

practically zero resistance

ü Meissner effect is where the magnetic fields are completely expelled by the superconducting state

ü crucial evidence for superconductivity

ü  discovered by Dutch physicist Heike Kamerlingh Onnes.

ü A superconductor can carry a current indefinitely without losing any energy.

ü They need to be cooled to very low temperatures, which restrict their use in our everyday life.

ü The ability to achieve superconductivity at ambient temperature and pressure therefore becomes very significant.

Observations

ü The team observed superconductivity in nano-sized films and pellets made of silver nanoparticles embedded in a gold matrix.

ü Superconductivity was observed at minus 37 degree Celsius

CRISPR-CAS9 stands for Clustered Regularly Interspaced Short Palindromic Repeat.

ü The name refers to the way short, repeated DNA sequences in the genomes of bacteria and other

microorganisms are organised.

ü CRISPRs are specialized stretches of DNA

potential applications include:

o Correcting genetic defects,

o Treating and preventing the

spread of diseases and

o Improving crops

TOTAL LUNAR ECLIPSE totality duration of 1 hour 43 minutes. The duration

makes it the longest total lunar eclipse of this century (2001 AD to 2100 AD)

 

 

 

ü Earth’s shadow can be divided into three parts:

o Umbra – the darker, central part.

o Penumbra – the outer part.

o Antumbra – the partly shaded area beyond the umbra

Total Lunar Eclipse

ü A total lunar eclipse takes place when the Earth comes between the Sun and the Moon and covers the Moon with its shadow.

ü When this happens, the Moon can turn redBlood Moon.

ü Total eclipses of the Moon happen at Full Moon when the Sun, Earth, and Moon are aligned to form line- alignment is syzygy

ü When the Sun, Earth, and Moon come together in a straight line, a total lunar eclipse takes place.

ü When the three bodies are aligned in a way that the Moon is partly covered by the Earth’s umbra, a partial lunar eclipse is the result.

ü On the other hand, if only the outer part of Earth’s shadow covers the Moon, a penumbral lunar eclipse takes place.

ü Earth’s umbra extends into space far beyond the orbit of the moon. This means that Earth’s Antumbra plays no role in lunar eclipses

 

Moon Looks Red?

ü Even though Earth blocks sunlight from directly reaching the surface of the Moon during a total lunar eclipse, the Moon is still visible to the naked eye.

because Earth’s atmosphere bends sunlight and indirectly lights up the Moon’s surface.

ü When sunlight passes through the Earth’s atmosphere, it gets refracted towards the Earth’s surface, and part of it—the colors with shorter wavelengths—gets scattered and filtered out, while

the rest, colors with longer wavelengths like orange and red, passes through the atmosphere.

ü This light is once again refracted towards the surface of the fully eclipsed Moon, thus illuminating it in a reddish-orange glow.

ü Because of this, a total lunar eclipse is sometimes colloquially called a Blood Moon

SCIENTIFIC RESEARCH INFRASTRUCTURE MANAGEMENT AND NETWORKS (SRIMAN)

proposed new policy which will be launched by Government to lease out time on scientific

instruments to researchers across the country

 

reduce the amount of time such expensive instruments remain idle.

NOT APPLICABLE initially to strategic sectors.

 

ü It plans to hire out to researchers all lab equipment that cost more than 10 lakh.

ü The policy if launched

ü The new system, according to the policy, envisages institutions declaring on a website how often

their instruments would be available for use by those outside the department or university.

ü Those who would like to use, for example, a DNA-sequencing machine, would have to pay a fee and specify the purpose and time they would want it for.

ü Currently, the practice of researchers bidding for time-slots to use lab instruments is typically seen more

with very expensive equipment, such as radio telescopes and particle-accelerators

BABIES FROM SAME-SEX MICE PAIR AND IMPRINTED GENES

 

A team of researchers has produced viable offspring from same-sex pairs of mice, using a novel technology that involves stem cells altered to remove certain genes.

 

ü Imprinted genes

o During the reproduction process, mammals mostly inherit two sets of each gene, one from their mother and one from their father.

o Imprinted Genes are a small subset of genes, which are inherited from only one parent.

o For these genes, the set produced by the other parent is effectively inactive, having been “shut off” when it is transmitted.

o If this “shutting off” process does not function correctly, the offspring could suffer from abnormalities or even die.

ü Example of Normal inheritance

o If a child inherits the gene for blood group A from either parent and the gene for group B from the other parent, the child’s blood group will be AB.

BLUE ROSES

a genetic engineering method to produce ‘blue rose’.

 

The study claims it to be the world’s first engineered blue rose

ü Blue roses do not exist in nature. However, florists can produce blue-hued flowers by placing cut roses in dye.

ü  a combination of genetic engineering and selective

breeding. However, the rose is more mauve-coloured than blue.

How was the feat achieved?

ü  two bacterial enzymes that together can convert L-glutamine, a common constituent of rose petals, into the blue pigment indigoidine.

ü When the researchers injected the engineered bacteria into a white rose petal, the bacteria transferred the pigment-producing genes to the rose genome, and a blue colour spread from the injection site

SKIN GEL AGAINST PESTICIDES

 

 

Chitosan is a substance found in the hard outer shells of crab and shrimp

ü  gel for topical application to prevent organophosphate-based pesticides getting absorbed through the skin.

ü The active ingredients of the gel are attached to chitosan so the gel does not penetrate the skin.

ü The gel does not act like a physical barrier but chemically deactivates the pesticides

About the harmful effects of organophosphate-based pesticides

ü  they bind and inhibit an enzyme critical for nerve and muscle function.

ü This causes neurological disorders, suffocation, paralysis, and even death.

ü The majority of organophosphate-based pesticides are absorbed through the skin while the nasal/inhalation route constitutes about 10-15%.

About Toluene

üone of the petrochemical wastes that get released without treatment from industries such as refineries, paint, textile, paper and rubber.

ü Toluene finds application in the production of Explosives and Foam.

ü It is a common solvent and can be used as an octane booster in gasoline fuels.

ü an intoxicating inhalant.

ü Toluene has been reported to cause serious health problems to aquatic life.

ü Studies also point that it has genotoxic and carcinogenic effects on human beings.

 

BEPICOLOMBO AND MERCURY ü BepiColombo is a joint mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) to the planet Mercury

ü ESA developed Bepi will operate in Mercury’s inner orbit while JAXA’s Mio will be in the outer orbit.

ü This is the second recent cooperation between the Europeans and the Japan Aerospace Exploration Agency after JAXA’s Hayabusa2 probe dropped a German-French rover on the asteroid Ryugu earlier.

IMMERSIVE E-COMMERCE ECOSYSTEM, AUGMENTED AND VIRTUAL REALITIES AND

HOLOGRAM

 

3D audio effects are a group of sound effects that manipulate the sound produced by stereo speakers, surround-sound speakers, speaker-arrays, or headphones
3-D audio processing

ü It uses head-related transfer function filters and cross talk cancellation techniques to transform sound waves to mimic natural sounds waves

ü It is thus able to trick the brain, to place different sounds in different 3-D locations upon hearing the sounds, even though the sounds may just be produced from just 2 speakers

 

 

Mixed reality (MR) experience combines elements of both AR and VR, real-world and digital objects interact.

 

What is immersive e-commerce ecosystem?

ü  platform built on technologies such as 3D audio, augmented reality (AR), virtual reality (VR),

digital scent, holograms and touch.

ü The viewers will be able to touch, feel, smell and experience products, with a seamless transaction(e-commerce) ecosystem.

About Augmented Reality (AR)

ü layers computergenerated enhancements

ü developed into apps and used on mobile devices

ü Augmented reality is related to two largely synonymous terms:

mixed reality and computer-mediated reality, which

merges real and virtual worlds to produce new environments.

ü AR applications for smartphones typically include global

positioning system (GPS) to pinpoint the user’s location and

its compass to detect device orientation.

ü Leaders of the tech industry are also using AR to do amazing

and revolutionary things with holograms and motion

activated commands.

Virtual Reality (VR)

ü artificial, computer-generated simulation or recreation of a real life environment or situation.

ü It is used prominently in two different ways:

o To create and enhance an imaginary reality for gaming, entertainment, and play (Such as video and computer games, or 3D movies, head mounted display).

o To enhance training for real life environments by creating a simulation of reality where people can practice beforehand (Such as flight simulators for pilots).

 

 

 

 

About Hologram technology

ü a photographic recording of a light field

ü used to display a fully three-dimensional image of the

holographed subject, which is seen without the aid of special

glasses or other intermediate optics.

ü The hologram itself is not an image and is usually unintelligible

when viewed under diffuse ambient light.

ü When a hologram is suitable lit, the interference pattern diffracts

the light into a reproduction of the original light field

FERMI GAMMA-RAY SPACE TELESCOPE, GREAT OBSERVATORY PROGRAM AND INTEGRAL

 

NASA has used characters from modern myths such as the “Hulk” and “Godzilla” to name its new set of 21 gamma-ray constellations constructed in celebration of its Fermi Gamma-ray Space Telescope’s 10th year of operations

 

INTEGRAL

ü International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is a currently operational space

telescope for observing gamma rays.

ü It was launched by the European Space Agency into Earth orbit in 2002.

ü It helps in detecting the mysterious ‘iron quasar’.

ü It was the most sensitive gamma ray observatory in space before NASA’s Fermi was launched in

2008.

ü INTEGRAL is an ESA mission in cooperation with the Russian Space Agency and NASA.

About FGST

ü The Fermi Gamma-ray Space Telescope (FGST) is a space observatory being used to perform gammaray astronomy observations from low Earth orbit.
