HUMANKIND VS. MOSQUITOES - Laser ‘PHOTONIC FENCE’ to protect from Mosquitoes


Mankind’s greatest enemy is tiny, brown, and very hard to catch. But now researchers have developed a new weapon which they hope will finally give them the edge they need to defeat the aggressors. It’s a battle which has been raging for centuries – an army of blood – sucking creatures just six millimeters long on the attack against enormous opponents. A single bite from this insect can be lethal, and some 6, 00,000 people die every year as a result. The enemy is the malaria carrying Anopheles female mosquito, and the tropical disease it transmits is often fatal, especially in the developing countries of sub-Saharan Africa. Without treatment, malaria can kill in a matter of days.


The only way to stay safe is to avoid being bitten. But the only means of achieving this are mosquito nets and insecticides. Both of these defenses can only be used indoors, and the aggressors quickly build up resistance to the chemicals. But we have now bright ray of hope from new invention by US research funded by the Bill & Melinda Gates Foundation: a “PHOTONIC FENCE” which kills mosquitoes by zapping them with laser.


How: When a mosquito flies to an area protected by a photonic fence – for example a school, hospital or village – cameras on both fence posts detect the intruder’s shadow in the light between the posts. The system immediately fires a non-lethal laser beam at the insect and uses the reflected light to determine its size and the frequency at which its wings are beating. This information tells the system whether the intruder is an Anopheles mosquito and also identifies the insect’s gender. This is an important distinction to make because only female bite. Once the mosquito is confirmed as a female Anopheles, the system fires a second, lethal laser beam, shredding the insect in mid-flight.

 

All the components used in the fence come from inexpensive consumer electronics, a fact which will hopefully make the fence affordable in malaria-stricken regions.

‘Bloody one Mosquito’ – will be no more powerful…

IMMORTAL MAHABHARAT – Lasers are making us virtually forever...! અમર મહાભારત - લેસર આપણને હંમેશા માટે વાસ્તવિક બનાવે છે..!


Eternal life is a dream that people have long shared. Even Lord Krishna and Arjun – the heroes of Mahabharat and the Kurukshetra war envied the god’s immortality. The reason we know that is because someone took the trouble to transfer those texts and information to the various new media that emerged over the centuries: First papyrus and carving on stone and clay tablets, parchment on leather, then paper. Nowadays, of course, we have digital copies of the Mahabharat on DVD, Pen drive and Hard Drives. But for How Long? “Nothing Lasts Forever” This phrase equally applies to the dilemma facing data and texts storage. If one day the Earth ceases to exist, there will be no memories of the world we used to inhabit, no more than stardust flying through the universe.

શાશ્વત જીવનનું સ્વપ્ન લોકો લાંબા સમયથી જુએ છે. મહાભારત ના મુખ્ય નાયક, ભગવાન શ્રી કૃષ્ણ અને અર્જુન અને કુરુક્ષેત્રનું યુધ્ધ પણ ઈશ્વરની અમરતાની અદેખાઈ કરાવે છે. બધુ આપણે જાણીયે છીએ એનું કારણ એક છે કે કોઈએ સદીઓથી બધા ગ્રંથો અને માહિતીને  સમયાંતરે  અલગ અલગ મીડિયામાં બદલવાની તકલીફ  લીધી છે: સૌ પ્રથમ વનસ્પતિનો રસ, માટીને લિપિને કે પત્થર કોતરીને, ચામડા પર લખીને, અને પછી કાગળ . અત્યારે જો કે આપણી પાસે મહાભારત ડીવીડી, પેન ડ્રાઈવ કે હાર્ડ ડ્રાઈવ માં ડિજિટલ કોપી તરીકે ઉપલબ્ધ છે. પણ આ બધુ કેટલા સમય સુધી? “કંઇ જ હંમેશા માટે ટકતું નથી” આ કહેવત માહિતીનાં સ્ટોરેજ ની મૂંઝવણ માટે સમાન લાગુ પડે છે. જો એક દિવસ પૃથ્વી અંત ના આરે હશે, ત્યાર પછી દુનિયાની માનવ વસવાટ ની કોઈ યાદગીરી હશે નહી, સિવાય કે બ્રહ્માંડ માં ઊડતી રજકણ..!

But, now there is solution of this dilemma. Researchers at Southampton University, UK invented disc using femtosecond laser pulses to inscribe micrometer – scale binary data on nano – structured quartz crystals, named ‘Transparent Crystal Disc’ the size of a two euro coin. Information to be encoded in five dimensions (5D), yielding a storage capacity of 380 TERABYTES, thermal stability up to 1000 Celsius and that the data in crystal can remain intact for 13.8 BILLION YEARS..!!! It seems we will still be able to captivate our ancestors with tales of his victory, for many centuries after the destruction of Earth, assuming we have found a different planet to live on by then..!


 પરંતુ , હવે આ સમસ્યાનું સમાધાન થઇ શકે છે. સાઉથમ્પટન યુનિવર્સિટી, યુકે નાં સંશોધકોએ ફેમટોસેકન્ડ લેસર પલ્સનો ઉપયોગ કરીને કમ્પ્યુટર ડેટાને અતિ સૂક્ષ્મ ડબલ ડિજીટ ઓપ્ટિકલ ડેટામાં રૂપાંતર કરીને નેનો સ્ટ્રક્ચર સિલિકાના પારદર્શક સ્ફટિકમાં ટ્રાન્સફર કરવાની શોધ કરી છે જેને  'પારદર્શક ક્રિસ્ટલ ડિસ્ક' નામ આપ્યું જેની સાઈઝ બે યુરોના સિક્કા જેટલી છે. મુખ્ય ખાસિયતોમાં, માહિતીને પાંચ પરિમાણોથી (5D) કોડ ભાષામાં રૂપાંતરણ, 380 ટીબી (ટેરાબાઈટસ) જેટલી સ્ટોરેજ કેપેસીટી, 1000 સેલ્શ્યિસ સુધી ગરમીમાં સ્થિરતા અને આ ડિસ્કમાં રહેલા ડેટા અધધધ 13.8 બિલિયન વર્ષ સુધી અખંડ રહી શકે છે...!! એવું લાગે છે કે કદાચ આપણે બીજા ગ્રહ પર જીવન શોધી લીધું હશે તો વિશ્વ વિનાશ પછીના હજારો વર્ષો પછી પણ આપણા પૂર્વજોની વિજયગાથા તાજી રાખી શકીશું..!!!

Technology Changed Face of Indian diamond Industry



The picture has changed, and for the better. No more squatting on the floor in dingy, damp units for your average diamond cutter in Surat, India. Instead, modern well-lit and well-ventilated factories, equipped with the latest high-tech machinery are common place nowadays. Certain sections of some of any large manufacturing facilities can put an IT company to shame, what with hundreds of computers interconnected within the premises. Certainly, this scenario is a far cry from the very traditional and rather miniscule cottage industry of yesteryears. Surely, Indian diamond cutting industry has come of age.


In the developing stages of the diamond cutting and polishing industry, say the mid-1970s or so, manual work was the order of the day. Usage of machinery and technology hardly existed in India. Most of the cutting and finishing was done by hand using developed skill and judgment; and of course using the hand-operated instruments that were available at that point of time. Surat was known as a place where most of the cleaving based cutting of diamond roughs was done. In other words breaking down diamond roughs into smaller stones was done here. Diamond is hard to break and so rejected diamond pieces were used to do this handiwork. Naturally, work was slow and only 5 to 6 pieces could be processed per day by each worker.


Around the 1980s, the Surat diamond industry was slowly introduced to new technologies from Germany and Israel, such as the laser based systems. Suddenly, production increased dramatically. Besides this, due to the laser technology, a huge reduction in margins of weight loss was seen while processing diamond roughs, which meant an increase in the number of pieces and therefore the profit margin. Also, the industry saw technology advancements in the process of bruting or girdling, whereby two diamonds are set onto spinning axles turning in opposite directions. They are then set to grind against each other to shape each diamond into a round shape. Both these technologies were the stepping stones for the industry, which started to flourish from then onwards.


Early 2000s, one saw a tremendous growth in the diamond cutting and polishing sector in India, with many players, big, medium and small entering the field. The reason was the potential that the industry offered at a time when the cutting industry in other centres was getting costlier to retain. India, with its cheap labour and the will to adapt and absorb high technology faster found the business a profitable proposition.

From a traditional manual cutting and polishing ways of the past, the industry soon became a tech savvy one by readily and quickly adopting new technologies the world had to offer. By utilizing hi-tech, speedy and effective software, Indian companies were a match or even better than their counterparts in Italy, Hong Kong, Belgium and even China. In addition, the shortage of highly skilled workers was met by using new technologies that were faster, accurate and even lowered the manufacturing costs.

In a short span of time, the Indian diamond industry made phenomenal high investments to adopt world-class technologies, like software that maps inclusions and flaws in the diamonds, and even equipment that generate cutting solutions with estimated yields. Also, green lasers that do not leave pronounced burn marks on the diamonds and hi-tech diamond calculator for gauging the light luster and fire of the stones were imbibed. Fully automatic polishing machines were a major hit too! The stage was set... the diamond cutting sector was rearing to go; and rest is recorded as the best years of the industry’s success story.

 

It goes without saying that the manufacturers of latest equipment and world-class technology too flourished along-side the industry. The big players like Israel-based Sarin Technologies Limited and OGI Systems Limited, India-based Sahajanand Technologies, Lexus Group and a few others grew multi-fold supplying software and high-tech diamond equipments. Lexus group introduced first-of-its-kind equipment known as `helium speed planner' with latest software for value-based planning and detecting impurities and cavities in the stones from the smallest 1 cent to 1 carat. This equipment was well received as detecting impurities and cavities in small-size stones and also enhancing the quality of small-size stones manufactured in India.

 

Today Surat, India’s main cutting centre is undisputedly the world’s biggest diamond manufacturing centre. With the technological implementations and advances that the centre has reached, it would not be wrong to say that it is at par or even better than any cutting centre in the world. Though, threat from China as a potential competitor is doing the rounds some industry members feel the threat is highly exaggerated, as the skill and technique required for cleaving of diamonds is something that no other country has been able to excel till date. However, with cheap labour available in China as in India, China cannot be written off altogether. China is said to be slowly establishing itself in manufacturing of ‘smalls’ too, which has been India’s forte till recent times. The key is skilled labourers who are in short supply; which calls for necessary training of workers in large numbers to sustain the industry. With the introduction of machineries and technologies, even the small and medium businesses in Surat started flourishing.

 

Sarin Technologies of Israel comes to mind when one thinks of Indian diamond sector’s technological advancement. The company first came to India in 1986 with proportions machine. Later, in 1998, it brought in the first diamond planning machines into the country and in 2000, the company came up with marking machines. The company is a worldwide leader in the development and manufacturing of high-tech planning, evaluation as well as measurement systems for diamond grading and gemstone production. The company’s other products are diamond cut grading tools for round and fancy shapes, rough diamond optimization systems, gemmology tools, diamond colour grading, and laser marking machines all of which have, in a big way, been instrumental to what the industry is today. Indian companies like Sahajanand Technologies have contributed too by introducing machineries used for processes such as laser cutting and stone shining. But most of the technologies and machineries are monopolized by the overseas companies, who also get royalty for usage of the machines.

 

IT technologies aside, there are diamond industry specific technologies that have helped the manufacturers in Surat to improve their business. For instance, Sarin has developed equipment for diamond scanning that shows inclusions (impurities) in a fully automated procedure. They have also come with laser sawing machine, machines for manufacturing stages. Sarin also provides services round the clock; have an education centre which trains people in groups of 20 to use latest technology and a service centre for 3D scanning of diamond roughs. For manufacturers to be able to achieve maximum of the planning process there is the software called ‘Advisor’, which processes these 3D scans for planning and for heavily processer intensive, Sarin Technologies has developed a new technology called 'Cloud'. Apart from this, Sarin Technologies provides software and hardware tools to track and control the complete manufacture process so that whatever is planned by the manufacturer is what is produced in the end to the precise accuracy expected. The new demand by the industry is inter-connectivity between the different offices of the manufacturers to monitor the stock in process and finished stock, as well as plan on inventory, etc.


The diamond industry is well aware that the technology, systems and processes need to be upgraded and modernized continuously and that it is an on-going process. And that this would help not only to achieve the next leap in growth but also to compete with rising international competition.
