Chairman’s Note
My Dear Students,
Among the 84 lakh species of living beings, human being stands out unique, special and extraordinary, owing to his reasoning, logical thinking, analytical, comprehension skills and more than anything, his capacity to imagine!
Our vision is limited to a narrow bandwidth, our audibility is limited to a small bandwidth and capacities of our senses are greatly limited. Despite all these limitations, human being is able to climb the top of the evolution ladder. All these are possible because of his skills and intelligence.
There is a budding scientist in every student, who is highly inquisitive and curious about various things happening around him. This curiosity should move us to the next stage of experimentation, observation, analysis and comprehension.
I am sure that ‘Vagdevi Vilas Vignan Patrika’ will kindle the scientific spirit in every student and help to transform into a budding scientist.
I congratulate and thank all those who have contributed to this news bulletin becoming a reality.

We are happy to present the September issue of Vignan Patrika. Since efforts have
been made to highlight the important events is the recent part. Schneider Electric India
foundation’s programme on ‘Conserve My Planet’ to sensitize the energy conservation issue among
students was well received by the students. Vagdevi Vilas proudly displayed school’s green
initiatives at Lalbagh during Independence Day celebration at Lalbagh during Independence Day
celebration week.
Tiny tots enjoyed hands on session in science and Maths lab. This issue also highlights about
various scientist personalities briefly their contribution. Students also wrote about eco-friendly
festival celebrations, currencies and interesting mushroom. Now quickly go through this amazing
newsletter for more reading.

Schneider Induction program in Marathahalli.
‘Conserve My Planet’ is a participative, educational training program to
build communities, sensitize students towards energy conservation an
initiative by Schneider Electric India Foundation for students of Grades 6,7 &8.
As a part of this programme, a special assembly was conducted on
31/8/2016 at Vagdevi Vilas School, Marathahalli. On this occasion several
programmes were organised. The chief guest of the programme
Sri. Nagarajan, Chief Executive, Schneider Electric India Foundation, gave
insight about importance of conserving the resources and need of such
educating programmes to support sustainable development. This program was
meant to educate the young minds about energy saving, energy efficiency,
green energy, recyclable sources and renewable sources of energy. A total
number of 100 students from grades 6,7and 8 were inducted as Green
Ambassadors and distributed green kit. Chairman of Vagdevi Vilas Institutions,

Clathrus ruber is a species of fungus in the stinkhorn family, and the type species of the genus
Clathrus.
It is commonly known as the latticed stink horn, the basket stink horn, or the red cage, alluding to
the striking fruit bodies that are shaped somewhat like a round or oval hollow sphere with
interlaced or latticed branches, has a fetid odour, it somewhat like rotting meat, which attracts
flies and other insects to help disperse its spores.
Although the edibility of the fungus is not known with certainty, its odour would deter most from
consuming it. C. Ruber was not regarded highly in tales in southern European folklore, which
suggested that those who handled the mushroom risked contracting various ailments. Though this
may look like a strange creature with tentacles at first to some, it is in-fact a fungus. It is also
known as the Octopus Stinkhorn, and it gets that name because it resembles an octopus .In its
early stages, it resembles an alien emerging from a pod.
It is native to New Zealand and Australia. This alien pod looking fungus actually has eggs that
are edible.

How to make an inclinometer
You can easily make you own inclinometer, for satellite dish elevation adjustment, which will more accurate than most cheap ones you can buy.
Instructions on how to make an inclinometer:
You need to print out the image below and stick it onto a piece of cardboard. Make a pinhole at the apex (centre of the small circle, near top left corner) and insert a length of strong sewing thread. Behind the card use sticky tape to secure the thread. At the front, attach a small weight, such as a 15mm or 1/2 inch metal nut, to the end of the thread, approximately 20 cm or 8 inches long, so the weight dangles down past the lower edge of the card.
How to print the square image: Put your mouse on the image above, and do right mouse click, then select "Print picture". After you have printed, check by measuring each way that the image has printed as an exact square.
Your printer will inset a left white margin. Don't worry, if you put the paper into the printer feeder straight then the picture will still be accurately upright and parallel to the left side of the paper. When attaching to a card make sure the left edge of the paper goes exactly to the left edge of the card so the left margin gap is parallel down the left side.

Your printer will inset a left white margin. Don't worry, if you put the paper into the printer feeder straight then the picture will still be accurately upright and parallel to the left side of the paper. When attaching to a card make sure the left edge of the paper goes exactly to the left edge of the card so the left margin gap is parallel down the left side.
How to use your inclinometer:-
To use it, simply place the left edge of the card against the surface you are trying to
measure. See installing a Prodelin VSAT satellite dish for a picture of the inclinometer in use. Always think about the angle and ask yourself if the meaning of the numbers make sense. Lowering the beam should reduce the elevation angle, down to zero at the horizon. Straight up is 90 degree. If the scale reads backwards in your case, don't worry; just count the degrees from the other end.
In the case of axe-symmetric, circular dishes, with 3 or 4 equal length struts supporting the LNB on the exact centre line, then the beam is at right angles to the central backing structure behind the reflector.
In the case of offset fed antennas, where there is a main feed support arm, normally at the bottom of the dish, and two shorter side support struts there is an offset angle. When the front face of the dish is upright the beam will have an elevation angle of perhaps 22.5 degree, 25 degree etc according to the specific manufacturer. To help in these cases, the manufacturer often makes a part of the metal structure so it is at right angles to the beam direction. This metal part may be the lower part of the spine behind the dish or form the rear part on a sloping boss fixture behind the middle of the dish. If there is scale you don't need this inclinometer
