We have got good feedback from all of you. Thanks for your co-operation and support. Whatever you are deep inside yourself reflects itself loudly and clearly through your behaviour. Our thoughts and emotions behind our behaviour leave their imprints on our face as a record of our past history. You are on the outside as you think inside. You sculpture yourself by your dominant thoughts. The expression of your face, the impression of your behaviour are the result of how you have conceived yourself to be. Thus what you are today is the result of your yesterdays. What you will be tomorrow depends on how you chisel yourself from now on. No one is the finished product. We are in the continuous process of sculpturing ourselves into newer and newer form. Only the quality of form depends upon the way we recreate ourselves, the way we chisel ourselves. You should rather concentrate upon becoming rather than on possessing; not on how you can have more, but how you can be more- more loving, more courageous, more joyous, more friendly, more forgiving, more humble, more patient, more helpful. You become a greater human being by striving to identify yourself with the best in you, by giving courageous expression to your ideals and values, to your gifts and talents. AGNOSCO Page 3 of 36 Scientists just made the world's smallest diode out of DNA. Researchers have shrunk down one of the fundamental components of modern electronics, creating the world's smallest diode out of a single molecule of DNA. In fact, it's so tiny, you can't even see it using a conventional microscope. Diodes are electronic devices that make it easy for current to flow in one direction, but not another. In other words, they're responsible for moving current around a lot of common electronics, and are printed by the millions onto modern-day silicon chips. But to increase the processing power of these chips, we need to make diodes a lot smaller, which is where DNA comes into it. When thinking about designing smaller diodes and electronics, researchers have long been focussing on using single molecules, since they're the smallest stable structure imaginable. But what they weren't sure of was whether it could control the flow of electric current, like a diode needs to. To be clear, no diode is perfectly efficient - in a perfect world, a diode would block 100 percent of current in one direction, and would allow infinite current flow in the other. But in reality, today's diodes still let a tiny current pass back and forth each direction. Overall, what defines diode is that there's an imbalance in how they transmit current, and the bigger that imbalance, the better. To get DNA to do this, the team took a single strand that was just 11 base pairs AGNOSCO long (pretty tiny when you consider inside every cell of our bodies we have DNA strands with approximately 3 billion base pairs all curled up). They then added a molecule called coralyne into the helix structure, and connected the whole thing to a tiny electronic circuit only a few nanometeres long. Surprisingly, the DNA turned out to be a pretty good diode, with the current flowing through the molecule 15 times greater for negative voltages than for positive ones. "This finding is quite counterintuitive because the molecular structure is still seemingly symmetrical after coralyne intercalation". Although the DNA diode was impressive, it wasn't quite as efficient as other single. But this one is a whole lot smaller than anything else out there, which means that you can pack more of them onto a chip and potentially create smaller and more powerful devices. The team is now looking into how they can further improve the efficiency of the DNA diodes to get them to one day compete with silicon diodes. And the possibilities are pretty exciting - just imagine finally being able to have functional electronics built on the molecular scale. The future is looking bright. The research has been published in Nature Chemistry. Page 4 of 36 The sound of your skull could soon replace your password more secure than "123456". Biometric security is taking over from the humble password, from the fingerprint sensor you might use to unlock your phone, to advanced iris scanning - and now there's a new method in the pipeline: the sound of your skull. Eventually, the required tech could be incorporated into smartphones, so holding one to your head to take a call would be enough to identify you. The name for the new system is Skull Conduct, and it joins various other weird and wonderful biometric security solutions in development, including ones using vein and brain waves. The idea is that these biological markers are much harder to fake, whereas if someone steals your password, you're pretty much out of luck. Scientists in Germany are working on a system that can identify the way your skull vibrates in reaction to an ultrasonic signal, because it could be just as unique as your fingerprint. It could eventually be used to prove you are who you say you are when logging into your email, or trying to gain access to the Pentagon. Of course, to measure skull vibrations you're going to need some kind of headset or accessory, and the researchers are currently working with a Google Glass-style device to log you in. AGNOSCO Page 5 of 36 WiTricity the future of electricity There is no argument in that we humans love electricity. We love that stuff so much that you can get an idea about it just by walking out on the street. There is about trillions of money spent in setting up power stations and wires carrying electricity from where it is generated to our homes and offices. Not only this. We love batteries too! An object that gives us power for a while before ending up in the garbage. But then there is a negative aspect to all this. Wires and batteries are awful. Just think about it, overhead wires gets damaged in rough weathers and can lead to calamities that can claim a human life. Plus imagine getting tangled in one of those wires under your computer desk. I know it’s pathetic. MIT Professor Marin Soljačić stood in his pyjamas looking at his phone. This was the 6th time in that month that he was woken up by the beeping of his phone warning him that the battery was low. In those moments a thought occurred to him. “There is electricity wired all through my house, my office and everywhere. The phone should take care of its own charging!” But to make this dream into a reality, one has to find a way to transfer power from these wired infrastructures to the phone wirelessly. Soljačić started working on a physical phenomenon that would make this possible. Imagine what if there was a technology through which we could built something that will never require us to plug our computers and phones into plug points ever again. That’s where wireless electricity (WiTricity) comes into picture. In this experiment, one of the coils was connected to an AC power supply having a resonant source. The other coil having a resonant capture device was connected to a 60W light bulb. They were suspended in mid-air by a nylon thread at a distance ranging from a few centimetres to 2.5 meters. The power supply was able to light the bulb wirelessly. As for the batteries, 40 billion of them are manufactured every year and when their work is done, they fall apart disintegrate and end up in a junkyard slowly decaying and releasing harmful stuff into the environment. The earliest vision of wireless electricity was thought by Nikola tesla. As great as an engineer and inventor he was, he dedicated his whole life to work with electricity. But his vision of a world running on wireless electricity was made possible for the first time by a MIT professor on his third sleepless night. AGNOSCO Soljačić with a group of MIT physicists was able to power a light bulb of about 60 watt from a distance of two meters wirelessly. It was around 50% efficient which is still a thousand times more efficient than what a battery would be to perform the same task. The concept behind it was called the resonant energy transfer. So what is resonance? When two objects vibrate at a same frequency they are said to be in resonance. And the frequency at which they are vibrating is called resonating frequency. The energy can be Page 6 of 36 transferred between two resonating objects at some distances. Try to understand it like this, inside a transformer there are two coils of wires. They are very close to each other and transfer energy from one coil to another magnetically and wirelessly. But this phenomenon occurs over a very short distance. What dr. Soljačić did was separate the coils in the transformer to a greater distance than the size of those transformers and make it work somehow. How WiTricity technology works? Imagine a coil with a capacitor attached to it. If we can make this coil to resonate, what happens is that it will pulse at a resonating current frequency which is fairly high. And if a “power capture coil” is brought close near to the source such that it will only work at the same frequency, what happens is the magnetic field will induce a current in the capture coil and a magnetic field around it. The magnetic fields of these two coils couple tightly and they transfer power efficiently. In simple words what’s actually happening is you convert electricity into magnetic field and take that magnetic field and turn it back into electricity to use it but over some distance. power transfer. Whatever the job may be difficult dirty or dangerous, wireless power delivers reliable and sustainable power. What is the future of WiTricity? We can look forward for a world in which wireless power is integrated in all parts of everyday life. Wireless electricity is still a very new concept and in its development phase but it holds a wide range of applications where it can be used. The applications where it has been tested efficiently ranges from household appliances to industrial applications. We have been able to charge cell phones wirelessly and have been able to turn on our television sets wirelessly. Wireless power holds potential for its uses in hospitals as it can provide a cleaner and more hygiene environment. It can be used in implanted medical devices which will reduce the infection. Imagine walking into your room and your desktop turning on automatically. Or imagine a wireless home where you place your lamp anywhere and it lights up or your phone charging while it’s still in your pocket. Imagine a world without wires. The idea is revolutionary! What are its benefits? This non-radioactive power transfer works on magnetic fields and is 100% safe in nature. It’s almost the same as the earth’s magnetic field. It reduces the cost when compared to wired connectors. Plus imagine how convenient it would actually be in day to day life for charging everyday electronics. It is also a very safe way of AGNOSCO Page 7 of 36 WATLY These huge solar-powered machines can provide an entire village's water supply. For many people living in developing nations, easy access to clean water is an ever-present struggle. It's estimated that 1.2 billion people in the world are living in areas where uncontaminated water is scarce, and the equipment needed for purifying it isn't always available. So a team led by Italian entrepreneur Marco Attisani has come up with a pretty ingenious solution - a new type of generator that's capable of using solar power to bring clean water, electricity, and even internet access to remote communities anywhere in the world. It's called Watly, and a prototype is already being tested on a village in Ghana. Its makers have opened up an Indiegogo campaign to fund an even bigger machine - one which would be able to help a community of up to 3,000 people. system also uses heat from the solar panels to distill the water, before it's put through a special mineraliser and acid reducer to regulate the water's pH level. Three 5,000-litre tanks store water inside Watly. That would be valuable enough on its own, but Watly can also recharge phones, lamps, and laptops, bringing electricity to remote communities that can be used for all kinds of purposes. Watly's makers say it uses a combination of radio links, existing 3G/4G networks, and satellite connections to get online - and separate Watlys can communicate with each other, too. The lifespan of one machine is expected to be around 15 years. India’s long pending problem can be solved if such devices are installed ……Clean Water….Less Disease!!! Here's how it works: the modular system inside Watly harvests energy through photovoltaic solar panels on its surface, and then stores it as electricity in its 140 kWh battery. Some of this power is used to purify and desalinate water from oceans and rivers. It requires lowmaintenance to run, and works without a connection to the grid. For water purification, Watly uses graphene-based technology to separate out soaps, solvents, and hydrocarbons, while a patented AGNOSCO Page 8 of 36 Nanogenerators: Pocket Powerhouses The development of an existing technology is measured is terms of increase in efficiency, selfsustainability and/or portability. Since the invention of the light bulb, we have always strived to find a better way to power it. First there was direct current, then alternating current; then the more portable sources like batteries, rechargeable batteries, fuel cells and technologies invoalving the use of alternative resources of energy (wind, solar, hydroelectric, etc.) to power electrical and electronic devices. But in the field of electronics, size is an important parameter as devices grow smaller and smaller every day whilst providing a greater amount of power and using lower input energy. There is energy everywhere around us in our living environment. It is up to us to figure out a way to transform this energy to do some useful work. If we just look at our body for example, it consists of neurons constantly firing electric signals throughout the body to process response and generate stimuli (electrical energy), it also consists of many links and mechanisms which do work like when we walk our footsteps generate about 67 Watts of power or our finger movement produces 0.1 Watts (mechanical energy), chemical reactions take place to release energy from our food to maintain our body temperature and metabolism (chemical and thermal energy). Even though these sort of outputs cannot power big electrical devices, if transformed accurately it can be used to power small electronic circuits. Nanogenerators aim to do just that. AGNOSCO In this article we will look into the Nanogenerators from conception to how they work to what they hold in store for our future. Figure 1 Nanogenerator circuit What Are Nano Generators? A Nanogenerator is a term used by scientists to describe a small electronic chip which transforms mechanical or thermal energy (produced by minute physical reaction) into electricity. They have an IC (integrated circuit) etched onto an elastic surface, called the substrate, which is basically the type of circuits that we would find in the electronic devices but at a minute scale as the term “Nano” () implies. Viewed from the naked eye, it looks like lines and boxes but, underneath all that (when viewed through a microscope) lies a complex system. The goal to be achieved by a Nanogenerator is provide selfsustainability to the Micro/Nano Systems by harvesting energy from its environment. It was first proposed by Dr. Zhong Lin Wang and his colleagues at Georgia Institute of Technology in 2006 Page 9 of 36 and they had developed the first Nanogenerator for a self-powered system. Mechanical is energy although small, is available in plenty in various forms in the environment. It can be light wind, body motion, muscle stretching, sound waves, noises, vibrations, blood flow etc. To convert the mechanical energy into electricity nanogenerators use arrays of “Nanowires” which are made of piezoelectric zinc oxide (ceramic) material. Piezoelectric materials produce a potential difference when they are strained. The strain is provided by the environment which these piezoelectric nanowire arrays convert to electric potential. The straining force results in a transient flow of electrons in the external load because of the “Piezopotential”. The advantage of using these nanowires is that they can be triggered by a tiny external force at wide range of excitation frequencies (One Hz to thousands of Hz). By combining the effects of thousands of such piezoelectric nanowires, a gentle strain can produce about 1.2V of electricity which can power an LED and a small LCD unit. Nano Materials for Nanogenerators Among the materials used in nanotechnology, ZnO (Zinc Oxide), a semiconducting ceramic material, is one of the most common choice as it has abundant configurations required from a nanomaterial. It has a wide range of applications in Optics, optoelectronics, biomedical science, sensors, actuators, energy and spintronics. Under normal conditions, it has a Wurtzite structure which is a type of hexagonal crystal system. Its structure is the main reason why it is a AGNOSCO widely used semiconductor. Although the whole unit cell is neutral, the lack of symmetry in the cell (a tetragonal structure within the HCP (Hexagonal Closely Packed) configuration, some of the surfaces of the material are terminated with a larger concentration of free charges. These polar charge surfaces give rise to some unique growth phenomena. The nanowires are mostly grown in hexagonal rod like or belt like shapes. Some of the common methods to produce nanowires are 1) Vapor-Solid-Solid (VSS) process; 2) Vapor-Liquid-Solid (VLS) process; 3) Pulsed Laser Deposition (PLD); 4) Chemical Approach. These processes produce nanowires in shapes of rods and belts depending on the various specifications needed. Each nanowire measures around 100 to 300 nm in thickness (0.0000001 to 0.0000003 meters!) and lengths of about 100 microns which is equal to 100,000nm (which is roughly equal to the width of two human hairs). Besides ZnO nanowires, other wurtzite structures like CdS, GaN and InN are being used for electricity generation. Out of these, GaN and InN are quite encouraging as they can produce an output voltage of about 1V per nanowire.

Films Get Cited in Do the robots of “Star Wars” or the genetically-engineered dinosaurs of “Jurassic Park” have any influence on real-world scientific research? Many scientists and engineers can probably list their favorite science fiction films that inspired their careers and work. But data science could help dig deeper into science fiction’s influence within the thousands of research papers found in online databases. Here is the list of popular sci-fi films that turned up at least two relevant search results. Not all the relevant search results represent physical science research; they also include film studies or social science results. (The film list also includes the dystopian film “Soylent Green” that isn’t necessarily among the most popular films, but was thrown in as a wild card.) 1. Star Wars (18 relevant papers) Type of research: The relevant papers on Star Wars focus on robots (R2-D2 and C-3PO as examples of (non-) humanoid robots), the psychology of Anakin Skywalker (can we diagnose him with Borderline disorder?), Star Wars fandom and the psychology behind The Force. 2.

Page 11 of 36 There are many facilities provided by our college, among which the most important and crucial service is the bus transportation facility which will get us to our destination with least amount of trouble. Though all people take driving as casually, but driving can be considered as an important task which require lots of patience, skilful handling of the situation and the most important is the presence of mind. Not only that, the college has noticed their sincere work and has awarded some of the members in order to encourage them. Our college has awarded “Best Performance Award”, to Lakshman. H. Jamdale. Let us take this opportunity to recognise their sincere work and express our gratitude towards their efforts, as they are the one who come to work in the early hours and lead us to the college at the right time in the morning and take us safely to our respective destinations in the evening. Our college transportation team is headed by Mr.Venkatesh Havanur, Professor (Dept. of mechanical engineering) SDMCET, and the team consists in total of 12 members, 5 buses in additional to the 6 other vehicles which are used in emergency situations like hospitalisation etc. The bus service covers almost half of the Dharwad, with an estimation that at least one bus per day traverse 80km i.e. 4 trips. AGNOSCO Page 12 of 36 PERCEPTION Firasat Mulla IV sem This is a college of honey bees and Biharis. Mechanical department was not ready to share the main building so This is a college of trains and trainings. God Bless You. This is a college of CATs not DOGs. For my CET verification I had to document come to SDMCET. I got down at Gandhi Nagar & reached SDM by walk. I entered with confusion whether it’s a college or Railway station? Moved on, walking in admin block, Oh! There is something on the other end! Arrrrr! It’s a bridge with ‘DUG’ ‘DUG’ ‘DUG’ ‘DUG’ sound when somebody walks on (fortunately now it’s being repaired). Looking at the buildings, again confused that I’m in a college or in the fort. Somewhat resembling with Golkonda Fort, Hyderabad. Gigantic buildings with full of stone walls, but princee is not hard like stones, very soft like Dharwad Pedha. Electrical department is in cave, once I feared to go, but feared to miss now. AGNOSCO rebelled and made a new independent ‘state’, very near to the temple. May Civil department, less explored but very important & dream branch of many in terms of Mar** and Atten***** Chemical department… I still ask my friends whether chemical department & department chemistry is one & the same?? of They say no. I ask why? Didn’t get answer yet. CS department, very innovative, everything is smart, from tiles of floor to the styles of students. Our sister branch department of E&C is very much accommodative, compromises smartest students to naughtiest students of the college. IS department is on the clouds, nobody goes and interrupt, except mosquitoes.

Welcome to SDM college Engineering and Technology of Page 14 of 36 DO IT YOURSELF LOW COST RADIO STATION We all wanted to make or create our own radio station where we can be a radio Jackie and entertain all friends by our thoughts, ideas well it is here, you can also create your own radio station and do all stuff that RJ do. Here I’m sharing the image of the circuit that I have created and done some wonderful experiment on it. You all know what components are used by observing it. AGNOSCO Vinay Navale ,VIII SEM I initially used to transmit songs of different movies on air and I used to tune the frequency that I made to operate and it was just fine. I nearly attain a range of about 200m which in my case sufficient. Later I used it to transmit the voice signal over air and found to use it to my school where it was huge success. So friends you can also try it and let me know how and in which way you will use it. Page 15 of 36 ONLINE TRANSFORMER MONITORING Madhu Ningareddy IvSEM INTRODUCTION: To safeguard and continuously improve the operational quality of electrical distribution networks, power customers are increasing their efforts to monitor every device on the distribution network. As a critical component of any smartgrid deployment, substation monitoring is key to these efforts. In order to observe the Power consumption status of distribution end-use sectors, power utilities hope to obtain real-time monitoring data from substations. This data is vital for analyzing the operational status of end-users and to detect potential problems, which may shorten outage duration, thus improving the power supply quality. Grid Router Monitoring for Transformer InHand Networks has over ten years of experiences in building wireless communication networks. For widely scattered distribution automation systems, InHand creates fast and easy to use 4G LTE and 3G network routers designed for real-time monitoring of substation performance, including GOOSE, DNP3, SMS and Modbus. AGNOSCO The InRouter900 series are the next evolution of InHand Networks’ trusted InRouter series. By integrating an embedded 4G LTE or 3G communication module and data acquisition solutions, the IR900 help customers avoid incurring additional cost for telemetry software and hardware. With InHand’s device cloud, the Device Network Platform, the InRouter900 will transmit operational data from the substation to the cloud monitoring center to achieve instant substation monitoring for thousands of devices spread over the grid. The InRouter900 also supports email and SMS alarms, so that when a malfunction occurs in a substation, the IR900 will quickly generate an alarm message and transmit it to Page 16 of 36 operations staff by email or SMS. Real-time online awareness allows technicians to shorten outage durations, prevent events such as rolling blackouts, and minimize impacts to the quality of consumer power distribution WHY InHand The 4G LTE or 3G InRouter900 delivers real benefits to power customers: Upgraded power supply efficiency and shortened outage durations, Less operations support costs with a central cloud platform, Rapidly repair malfunction with functionality, AGNOSCO any alarm Quick responses unexpected problems. to The InHand solution for substation monitoring is designed for scalable, quick deployments with no downtime, ensuring positive budgetary performance. Substations become intelligent, allowing customers to detect and solve potential problems in the distribution network quickly and efficiently. With the embedded data acquisition and local alarm functions in the InRouter900, customers can enjoy real-time monitoring of the substations with upgraded fault response efficiency and reduced on-site support. Page 17 of 36 The Missile Woman of India Dr.Tessy Thoma's moniker " Agni putri " or " The Missile Woman of India ", hails from her works in the field of Agni 3, Agni 4, and Agni 5. She likes her title even more because her role model and mentor Dr Kalam is called the missile man of India. Tessy Thomas was associate project director for the three thousand kilometer range Agni 3 project. Agni-III is an intermediaterange ballistic missile developed by India as the successor to Agni-II and is capable of engaging targets deep inside neighbouring countries. The missile's Circular error probable (CEP) is within 40 meters range, which makes it the most sophisticated and accurate ballistic missile of its range class in the world. She was project director for the Agni 4 project that was successfully tested in 2011. Agni-IV is the fourth in the Agni series of missiles which was earlier known as Agni II prime. When photographs of jubilant Defence Research and Development Organisation(DRDO) scientists appeared after the may 7 launch of Agni III, Tessy was the subject of many a question. But the 53 year old associate project director of Agni missiles takes the curiosity in her stride. What matters is that her gender is not called into question at her workplace. ’Here, I AGNOSCO Dharani. P IV SEM am considered as a scientist and not a woman. But it has to be taken into account that the job with DRDO comes with a responsibility; it is for one who can understand the criticality of the work,’ the woman from Alleppey in Kerala said. ’It was the determination of my mother that kept me going. My M.Tech degree in guided Missiles gave me an upper hand. Also I joined under Dr. A.P.J .Kalam and have worked under seniors who always encouraged me’. Former Prime Minister Manmohan Singh told to the Indian Science Congress that Mrs Thomas is an example of a "woman making her mark in a traditionally male bastion and decisively breaking the glass ceiling". Tessy Thomas was conferred the Y. Nayudamma Memorial Award in the year 2014 and She was awarded Lal Bahadur Shastri National Award by President Pranab Mukherjee in the year 2012 for her outstanding contribution for making India selfreliant in the field of missile technology. She is also an example for a woman who is doing her best in a male dominated society of ours.

But could lightning ever be harnessed as a useable power source in the future? At first sight it appears promising because a lightning bolt, which has over five billion Joules of energy, which could provide one household with all their energy needs for a month. However, Doc Brown had an unbeatable advantage over us – he knew when and where the lightning was going to strike. In the UK we experience relatively few thunderstorms each year: in England thunder occurs on average 11 days per year, with even fewer in Scotland and Wales. Even during a thunderstorm it’s incredibly difficult to predict when and where lightning will strike. Sushma.Pattanshetti IV SEM conductor, there would be major difficulties in storing the energy and then converting it to alternating current so it can run your appliances. In addition, any solution to these problems would need to be able to withstand the enormous surges in energy generated by each strike. Finally, much of the lightning bolt’s energy goes into heating the surrounding air to temperatures greater than the surface of the Sun. So even if you managed to overcome the problems of collecting, storing and converting the energy from the lightning to make it useful, you would still only be harnessing a small proportion of the lightning bolt’s power. Assuming that you are lucky and get a lightning bolt to hit your AGNOSCO Page 19 of 36 DOES GOD EXIST? Pushpa chawhan,VI SEM and love for you. Free my mind from impurities please make my heart your permanent abode”. Make up your mind, make a whole hearted sacrifice, to accomplish the greater task in life, God never considers the magnitude and type of the work you do but observes our love, devotion with which it is done. Our spiritual progress does not depend on the change of place or work. The nature of God is a circle of which Centre is everywhere and circumference is nowhere. God is in history. God is in science, God is in our conscience and all these are one. Whenever you pour sugar in water after some time may see that the sugar is dissolved, you cannot see that, but you can feel the presence of sugar only when you taste it, similarly you may feel the presence of God after undergoing certain duties and circumstances. A devotee prays to God to get rid of mental impurities, lust, anger, greed, passion, pride and jealousy. A Sadhaka never aspires for empheral world, his inner single objective is to see the light and peace. ‘A prayer of Tulsidas has the message “oh! The lord of all souls! I tell you this truth, I have no other desire.” Give me the true devotion AGNOSCO The best way to stay where we are and do all our duties for the love of God. For years together man may go on arguing and reasoning in vain. But God reveals subtle spiritual truth and his glory to the simple and humble devotees. Now there is no question of believing. I see God every moment and longer I believe, for I can see and experience God knocking at the door, keep on knocking and some or the other day God feels your devotion and will open the door of his grace. Swami Vivekananda said “God favors those who sincerely struggle to realize him, if you are too idle to do anything for God, you can take granted for that he will never come to you. Grace is given to those who are constantly struggling for it and never to lazy people”. Sri Ramakrishna said, “His Grace is blowing day and night unfurl the sails of your boat and make of crooked thoughts.” etc….. Page 20 of 36 We can offer prayers by standing or sitting before the image or picture of our favourite deity. It is true that those who can visualize the picture of God in their heart need no external image to pray. The essential requisites of a prayer are devotion, faith and earnestness. Those who would like to pray should constantly repeat the name of the Lord, regularly worship and meditate on their chosen deity, read sacred books, recite hymns like Ramarakshastrotra and Lalitasahasranama, observing fasting, devotional prostrations to God (Sahtangaparnams) and yeam for God’s grace with all humility. These spiritual disciplines gradually purify the inner self and help him to get his vision, of course, God is all powerful, merciful. He who has taken shelter at the feet of God, does not need to fear anything. Your present difficulties of today will not throughout the life. Like the water flowing under the bridge, difficulties will disappear, don’t lose your patience. Be not anxious, be patience. All the difficulties that arise in life have a meaning, they have cause. But don’t regret what is past .God watches everything. He hears every word of your prayer. Don’t blame God for not getting what you prayed for. God. No pain goes in vain. Electricity flowing through the electric wire is invisible, but the glowing bulb confirms its presence. Similar to the grace of God flows through the wire of faith and devotion. Repeating the holy name AGNOSCO one can experience it. Hence repeat the name of God. When gold is melted in fire, it becomes pure, we realize that the world is full of sorrows when afflicted by difficulties. There is no real shelter for us, other than the feet of God. There is no way left for us than to surrender to God. Pray to God, whenever you face difficulties. God will certainly show you the way out. Just as the electricity generated in a main power station, is supplied to various places, the great souls who have touched the feet of God spreads spiritual awareness everywhere. This is not s figament of imagination but a fact of experience which nobody can deny thanks to modern science and technology of ours. Similarly we also get an insight into the microscopic existence of matter more commonly as microcosm. Modern science gives us an insight into the subtler aspects of matter. Without going into details aspects of matter. Without going into details one statement about the ultimate nature of matter would suffice; the atoms are particles of the size of about one tenth million of a millimeter in diameter. Every atom is composed of sub-atoms called electrons , protons and neutrons and this wonderful universe is built by these bricks of basic subtle material particles. A perfect order and telling harmony are seen in movements of huge stars in the sky and in movements in Page 21 of 36 minute electrons of the physical bodies of men, animals and plants. Modern scientific researches in the west have demonstrated through physical means the solidarity of the unity of the whole universe. Going one step further it indicates the idea of the unity of the whole show – the highest spiritual reality in which we live, more and have our being. The contemplation of cosmic harmony reveal the existence of a supreme being everywhere. The great scientist Einstein, describes this unity and harmony, thus” My religion consists in a humble admiration of the inimitable superior spirit who reveals himself in the slight details we are able to perceive with our frail and feeble minds. That deeply emotional conviction of the presence of a superior power forms, my idea of God. This is not an easy task. It cannot be achieved in a day or two. With an unrelenting longing to realize God, we have to proceed on this path. The day has stuck in ma head…… The day has stuck in ma head. I am still in deep sleep in ma bed. We together were climbing high and high. Suddenly she told me lie. Was that her mistake? No no no it was just a havoc. I was just out of ma mind. B'coz simply she didn't reply. Even a single minute I didn't cry. But still i am waiting for her reply. Hoping someday she'll give me reason of ma why. That why did she not reply. Well everything will be gonna all right. Again we will together fly like a kite. The day has stuck in ma head. I am still in deep sleep on ma bed... - Prabhakar Narayan,VI SEM AGNOSCO Page 22 of 36 Fresher’s day Ganesh Wadikar IV SE In every student life there is one day, which he remembers throughout his life other than his birthday is his fresher’s day in degree life. Yadein mithai ki dibbe ki tarah hote hain…ek baar khula toh sirf tukda nahi kha paoge…!!! Jabhibhi tum kisi insaan ki yaadon ki nagari mein jhaank kar dekhoge toh bahut saari kahaaniya dikhengi. Kuch ankahi hongi toh…kuch ansuni hongi..aur kuch adhuri kahaaniya bhi milengi…! Unhi yaadon ki baraat mein kuch aise lamhe baste hai,,jinhe voh aakhri saas tak nahi bhool payega… Aur unhi sunhere lamhome lamha hota hai ,,, ek Vidyarthi jeevan.. Student life…! Ji haaan… Mein unhi lamho ke barein mein baat kar raha hu jise hum abb bahut enjoy kar rahe hai..aur bahut jaldi, bahuuut… miss bhi karne lagenge. AGNOSCO Immediately after the start of academic year fresher’s start dreaming about fresher’s day. The very purpose of fresher’s day is to welcome new comers in a friendly atmosphere and to encourage their confidence, It is a day where seniors and juniors finally bond and unite to celebrate being part of college, The stage is set for fresher’s to show case their talent and compete for Mister & Miss fresher crown. Yup... One such saccharine moment which was the mixture of little bit of excitement, little bit of perplexion, and with huge amount of hope to come forth with surpass in the field of technology, took place in our lives. The rationale for excitement was, the events which were organized by our wonderful seniors to encourage and to get us the crown of miss & mister fresher which was the supremacy of the event and it was grabbed by my pals Yashasvini and Arun. And motive ragging..! for perplexity was Page 23 of 36 After going through this word every junior’s heart stops for a while. But I was in hurry to get ragged, with this kind of mindset also fear was residing in some corner of me. Many things were running in mind like what will I do if it become 3 idiots type of ragging “Jahapanah tussi great ho..Taufa kabool karo”. But it was joyful just because of our soft hearted seniors, who made it healthier, fun filled act for us. Different kind of dares were given to us, someone was asked to offer a flower to unknowns present there and to ask their names, Another one was asked to introduce himself and to sing a song for them. Like others I was also asked to perform some dare, which was bit different than others, ಕನ ತo ೕ ರ ಮನ ದ ೕ ವ ಗ ಗ ದ ನo ಅ ಈಬ ನ- ನ ಸತನ ಪ ಕ ನ ಗಳ ಮ ಘ ಗಳ ಅ ಭ ನ- ನ ಸ ಗಳ o ಕನ ಗಳ ವ ನ ಎ ಈ ಕನಸಗಳ ನನ ಈ ಮನ ಸ ನವನ ಕ ಸಗ - ೕವನ ಸ Arpita Yamanur IV SEM I was asked to describe a gorgeous girl present over there, I just did it with these words, “ ಅ ದ ಂದರ ರ ಂ ಕ ಂದ ಗದ ರ ” ಅಂದವ ಲಯದವ” Like this a marvelous event came to an end with lots of inerasable memories.
