Ally 02 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 T he Leo club of Kalubowila together with the Leo club of Piliyandala organized a programme for Middle aged men and women living in the coastal area of Dehiwala for a better life. The programme was held at Sip Sewana. The programme was graced by our very own Lion Kamal Seneviratne and Lion Lady Delrusha Seneviratne who addressed the gathering together with the Chief Guest Noel Palliyaguru and Rev. Daya Perera, was very influen- tial to many who gathered that day. Meanwhile, us the Leos were having a special programme for the children of the parents who attended the drug prevention pro- gramme. We divided ourselves among the different grades and taught them Sinhalese, Mathematics as well as English. An art competition was followed afterwards for all the kids. The kids and the parents were treated with a nice cup of tea and a piece of cake. It was a day filled with lots of joy and laughter. A BETTER LIFE Creating Together Sip Sewana was a place that brought a lot of memories from the past for the Leos of Kalu- bowila, since it was a place that so many good programmes were held in the past from the club and it was nice to go back for another worthy cause. Ally 03 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 Y outh Against Cancer is an International Twining Pro- ject by Leos of Leo Club of Mattegoda, together with 25+ countries and 248 Leo Clubs around the world. We planned to initiate this project around Mattegoda Area. We got some Leaflets and booklets to distribute from the Cancer Hospital. Leos got into the buses, went into the shops and distributed the leaflets among people while an- nouncing some important chapters copied from the books. We received handmade Cancer Awareness Symbol pins to hand over to the crowd we were speaking to. We gave those pins to them to wear it and support for cancer awareness. We discussed around the people at the Mattegoda Bus Stand and asked their suggestions to improve these kinds of programs. An email campaign was launched to all the Leos in Sri Lanka mentioning about what are the types of cancers and how we can get rid of it and what are the im- mediate prevention methods we can practice for cancer. cancer Youth against Ally 04 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 N idahas Sarisara 2019 was the Annual Club Trip of Leo Club of Mattegoda. It was held on the 04 th February 2019 around Galle. As it was the Independence Day we wanted to celebrate and serve freely. Leo Pasindu Alwis who was the Project Chairman, planned this very well to have a great ex- perience. We explored the Kanneliya Forest Reserve and Galle. In exploring Kanneliya Forest reserve we got into the Falls which was a valuable experience and had a lecture about the Forest Reserve as well. Exploring Galle also quite interesting as we spent time at the beach, had lunch, enjoyed the breeze, played a match of tap rugby, a good swim at the sea. We all had a first time experience in surfing the waters as well. We all joined hands together to clean the coastal area near the lodging place. We were proud of how the neighbors around almost kept the surrounding clean. With that, we got time to speak with people around and foreigners as well. Hence, it was in- deed a memorable day for all Leos. a Ally 05 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 urodk 2 F RT දේ ශී ය දෙන්ෙ වි දේශීය සංචාරකයන් වි ශාල පි රි සක් දකාළඹ දකාටුව සහ ෙරදාන අතර දු ම්ර රි ය ොර්ගදයහි දදනිකව ගෙන් කරනු ලබයි. දම්ර දහේතුව නි සාෙ එෙ පරිශ්‍ර ය තතා වි ශාල දලස දපාලිතීන් සහ ප් ලාසේික් වැනි අපද්‍ර වයයන් දගන් අපවි්‍ර ී තත. දෙෙ තත්තත්තවය පාරිසරික වශදයන් හානිදායක වන අතරෙ සංචාරක කර්ොන්තය දකදරහි, දදනික ජී වන රටාවන් දකදරහි ද සෘජුවෙ බලපාන කරුණක් ී ති දේ. ශ්‍රී ලංකාදප රධාානතෙ නගරයක් වන දකාළඹ නගරය දෙදලස කැළිකසළවලින් අපවි්‍ර ී ෙ සංචාරක කර්ොන්තය ර වර්ධානයට වි ශාල බාධාාවි.. එබැවින්, දෙෙ පරිශ්‍ර ය පි රි ිද දු ි. ීම ෙ අරුණු කර ගනිිනන් පරිසර හි තකාමී වි දශේෂ වයා පෘතියක් පි ළි යන්දල ලි දය සො ය “ FORT 2 MARADANA” වයාපෘතිය ිද දු කරන ල. . දෙෙන්න් දකාළඹ දකාටුව ිද ට ෙරදාන දක්වා වූ දු ම්ර රි ය ොර්ගයට බැහැර කර තති ප් ලාසේික් දබ තල් සහ දපාලිතීන් වැනි අපද්‍ර වය තවත්ත ි. ීම ෙට කටයුතු කළ අතර එය දකාළඹ දකාටුව දු ම්ර රි ය සේථානදයන් ආරම්රභ කර ෙරදාන දු ම්ර රි ය සේථානදයන් අවසන් වි ය.

This project was aimed at eradicating hunger from Sri Lanka and it was a great experience for the Leos of both clubs to foster fellowship. About 50 lunch packets were distributed among helpless people. And it was indeed a good op- portunity to show the society how we could take small steps in order to make this world a better place. Ally 08 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 T he Leo Club of Rahula College along with the Eng- lish Unit of Rahula College organized a one day Eng- lish Camp; “Rahal English Camp” for the grade 7 stu- dents of the school. On the 15th of February, the Camp was successfully held with the help of English teachers of the school, from 2.00 p.m. onwards. A campfire and a dinner was followed afterwards. Par- ents of grade 7 students and the old boys handled the financial aspects. The Leos contributed in organizing this event, in order to uplift the English teaching- learning system and polish up the skills of students. Entertainment programs and games were held to pro- vide some relaxation to the stressed lives of students as well as teachers. 316 students took part in the pro- gram. The support of the principal Mr. F. Welege and the staff advisor Mrs. Chandani Siriwardena led to the huge success of the program. Ally 09 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 L eo Padura, one of the main annual events organized by the Leo Club of University of Moratuwa was held on the 20 th of January, gathering many Leos and Lions from the Leo Multiple District 306A2 together. It was indeed a wonderful evening showcasing all the singing and dancing talents of our fellow Leos from the district. Not only with singing and dancing acts, but also the crowd was entertained with a drama performed by the Leos of the Leo Club of University of Moratuwa. One new notable difference added to this time was inviting some of the great figures in Sri Lankan Field of Art, and appreciating them over the contribution they have done on behalf of the improvement of the field. Mr. Jayathissa Alahakoon, Mr. Karunarathna Amarasinghe and Mr. Athula Ransirilal were some artists among them. Leo Padura once again gave an excellent platform for many Leos to showcase their aesthetic talents . Ally 10 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 I n a society where women need to be more aware of self-defense, Leo Club of University of Moratuwa orga- nized yet another women empowerment program to en- sure the safety of female students of the university. UoM Leos joined hands with Mora Karate; the Karate Team of University of Moratuwa and conducted this event in the evening of last 25 th of February to give some basic knowledge and experience on self-defense. The guidance to the program was given by Mr. Pradeep Satharasinghe, the Representative of ISKF Sri Lanka branch and IKMA Sri Lanka branch, together with the support of members from Mora karate. This event was highly appreciated by the participants as it was an un- imaginable experience for them, and that it has devel- oped self-confidence and discipline in themselves. uper ero xperience Ally 11 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 ksoyia osk ieureu 71 wNsudkj;a jk - චන්. දේ ෙරත්තන දොරටුව වි ශේවවිදයා ලීය ය ලි දය සො ය Ally 12 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 Interview with Leo Sadev Kalubowila Leo Club of Sri Lanka Technological Campus How do you introduce i-cap? It can be simply explained as a security system for threaded fasteners. (Nuts and Bolts) Why such security system is required? We all know that threaded fasteners are use to assemble parts in every field all over the world since the industrial revolution. But failure (loosening or breaking) of bolts lead to damages of valua- ble property endangering many lives in every year. As you can remember, on 19.03.2012 Sri Lanka lost a valuable life of a youth due to failure of a bolt of a train foot board at Veyangoda sta- tion. Searching the Internet, we can have a summary of bolt fail- ure accidents all over the world. So, inventing a security system to avoid this preventable nut and bolt failure is a must. Does your invention “i - cap” helps to stop bolt failures? No. “i - cap” helps to detect possible bolt failures which are happening silently. At a glance we cannot identify a loosened bolt. But if you apply an “i - cap” to a bolt, it will warn you by showing a red color even at the initial stage of loosening of that bolt. Additionally, it will start a warning alert electronically. So, the user can take appropriate actions to prevent this possible bolt failure. Is “i - cap” expensive? It is inexpensive and can be easily applied to new or even for existing bolts. Ally 13 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 What is the application process? This product is available as a cap. After tightening the bolt user must push the “i - cap” around the bolt and paste it. To apply the electronic alert sys- tem, two terminals of the “i - cap” should be con- nected to the circuit. Who are the beneficiaries? ? Every field all over the world will have benefits. From simple machine to air crafts, ships, huge cranes have visible or invisible fasteners which play a vital role in holding their parts together. Although they carry numerous lives and properties, checking every single bolt before a jour- ney is impossible. “i - cap” is the emerging solution for this problem. It will warn failing fasten- ers at initial stage so, users can take appropriate actions to save the whole lot of trouble which will come later. What are your future implements? My aim is to develop this product using Android and IoT. So, in near future you will receive alerts to smart phone about your valuable machines and vehicles located far away from you. Further, this can be used for important valves, lids and caps. How it works? “i – cap” has a special mechanism to change its own color according to the condition of the bolt. In a well tightened bolt “i – cap” only shows green color indicating that it is not loosened and it is in its original position. When the bolt is getting loose, green color will gradually decrease and red color will appear. Whole area becomes red after complete loosening of 1 st round. Luminous colors are used in “i – cap”. So even in night, a flashlight will clearly show loosened or broken, nut and bolts. With the help of the electronic monitoring system, we can monitor bolts even from a distance Cont..

Black holes are extraordinary cosmic objects with enormous masses, but extremely compact sizes. Therefore, the gravity of a black hole is higher than nowhere else, so that it is a region of space from which nothing, not even light can escape. Despite the name, they are not empty but instead consist of a huge amount of matter packed densely into a small area, giving it an immense gravitational pull. According to the theories presented regarding black holes, there is a region of space beyond the back hole called the “ event horizon ” which is a “point of no return”, beyond which it is impossible to escape the gravitational effects of the black hole. A s you all know, recently the cyber space was con- quered by this first ever image of a black hole. This im- age was the front page news all over the world and even laypersons in the fields of astronomy and physics started probing about black holes, dark matter and ex- traterrestrial space. The questions which aroused curi- osity in many of us were “what is a black hole?” , “why isn’t the black hole black?” , “how can some- one photograph a black hole?” and “what happens if a black hole comes to us?” . Let’s find out. Why isn’t the black hole black? The image shows a bright ring of light around a dark region similar to a shad- ow. This shadow is caused by gravita- tional bending and capture of light (originated by various gases) by the event horizon. Simply, the “ bright ring of fire ” around a black hole is formed as light bends in the intense gravity of a black hole which is approximately 6.5 billion times more massive than our sun, around which the whole solar system orbits. As described by scientists, the bright ring around the black hole which seems to be yellow-orange-red in col- or is caused by superheated gas falling into the hole. This light is said to be brighter than all the billions of other stars in the galaxy combined; which is why it can be seen even from earth at a distance of 500,000,000 trillion kilo- meters The recently photographed black hole is larger than the size of our entire solar system and it measures 40 billion kilometers across; three million times the size of the earth. This led the astronomers and physicists call this black hole in galaxy M87 as “a monster”. Ally 17 THE OFFICIAL NEWSLETTER LEO DISTRICT 306 A2 ISSUE 04 BLACK HOLE THE “NOT Black” Cont... How to capture an image of a black hole? As I’ve said earlier, the black hole in galaxy M87 was photographed recently, using a ra- dio telescope system called the Event Hori- zon Telescope (EHT). The EHT is not a single telescope at all, but a network of radio tele- scopes all over the world making precisely timed recordings of radio waves all together, and these recordings can be combined such that the different telescopes act as one. This high-tech worldwide network of radio tele- scopes consists of 8 telescopes deployed at high altitudes in far-distant locations such as volcanoes in Hawaii and Mexico, moun- tains in Arizona and Spanish Sierra Nevada and glazier mountains in Antarctica. When Einstein’s theories about black holes came into debate in the 20 th century, no one thought it was possible to capture an image of a black hole. But in 1993, Prof. Heino Falcke, of Radboud University in the Nether- lands, realized that a certain type of radio emission would be generated close to and all around a black hole, which would be power- ful enough to be detected by telescopes on earth. He himself was the founder of the pro- ject “ The Event Horizon Telescope Array ” and eventually succeeded in capturing the very first image of a black hole. Now the EHT is imaging a supermassive black hole at the center of our own galaxy, the Milky Way. Odd though it may sound, that is being harder than getting an image from a distant galaxy 55 million light years away. This is because for some unknown reason, the “ring of fire” around this black hole is smaller and dimmer. What if a black hole comes closer? Most of the physicists believe that the “ end of the world ” will occur due to the effect of a black hole coming closer to the earth. Though there have been no evidences of such a black hole which can devastate our solar system, scientists estimate that there are as many as ten million to a billion black holes in our galaxy; the Milky Way alone. One of the best-known effects of a nearby black hole has the imaginative title of “ Spaghettification ”. In brief, if you stay too close to a black hole, then you will stretch out, just like spaghetti. This effect is caused due to a gravitation gradient across your body. Imagine that you are headed feet first towards a black hole. Since your feet are physically closer to the black hole, they will feel a stronger gravita- tion pull towards it than your head will. Worse than that, your arms, by virtue of the fact that they’re not at the center of your body, will be attracted in a slightly different (vector) direction than your head is. This will cause parts of the body toward the edges to be brought inwards. This imaginative theory figures out how matter is deformed due to the gravitational effect of a black hole. But the scientists know that nothing will remain to be “spaghettified” due to the super -high radia- tion near a black hole which makes its “ring of fire” glow brighter than billions of stars combined.
