- The satellite was selected through a competition called ‘Cubes in Space’, jointly organised by NASA and ‘I Doodle Learning’
- This will be the first time an Indian student’s experiment – a 64 gm satellite – will be flown by NASA
The satellite, called KalamSat, will be launched by a NASA sounding rocket on June 21 from Wallops Island, a NASA facility. This will be the first time an Indian student’s experiment will be flown by NASA.
What can we say. This is something simply extraordinary. The Prime Minister of India should take notice of this boy’s intellectual ability and provide him all necessary support to continue his appeti…
Speaking to TOI from Pallapatti, Rifath said it will be a sub-orbital flight and post-launch, the mission span will be 240 minutes and the tiny satellite will operate for 12 minutes in a micro-gravity environment of space. “The main role of the satellite will be to demonstrate the performance of 3-D printed carbon fibre,” he explained. He said the satellite was selected through a competition called ‘Cubes in Space’, jointly organised by NASA and a organisation called ‘I Doodle Learning’.
The main challenge was to design an experiment to be flown to space which will fit into a four-metre cube weighing exactly 64 grams. “We did a lot of research on different cube satellites all over the world and found ours was the lightest,” he said. Rifath said the satellite is made mainly of reinforced carbon fibre polymer. “We obtained some of the components from abroad and some are indigenous,” he said.
During these last half-century of my life I have seen many types of Invitation to many occasions . Such as normally for betrothal ceremonies,Marriage invitations,New house entering ceremonies,Name suits,Ear punching etc. That too printed with many tastes: Its vary from palm leaves, small and tiny sizes, very big sizes with so many handy works, tied with knots, with Gods pictures, with bride and bridegrooms pictures, even with political leaders photos which party they belongs, with so much of cost to refer their wealth of families, in papers, in cloths, in metal plates and so on.

Using bio fuel to run an irrigation pump for five acres
At a time when farmers in Tamil Nadu are facing a big problem in cultivation due to frequent load shedding, a farmer, Mr. Mr. C. Rajasekaran, from Vettaikaran Irruppu of Kilvelur taluk in Nagappattinam district does not seem to worry much.
The reason is not far to seek — he is using oil from Punnai (Tamil name) tree seeds (Calophyllum inophyllum) to operate his five hp motor pump for irrigating his five acres.
His garden, which was once considered to be unfit for any cultivation, since the soil became barren after the tsunami struck, is now home to nearly 35 different tree varieties. Mango, Guavas, Lime, Teak, Cashew, amla, tamarind, and jack are all flourishing well today in what was once considered a wasteland.
While the farmer says that he was able to turn the land fertile only through organic practices, he is well known in the region for propagating the usefulness of punnai seeds.
“If a farmer has two punnai trees on his land, he can reduce the diesel cost considerably. I run the motor for about five months using the oil during summer,” he says.
The tree grows well in coastal regions. Cattle or goats do not eat the leaves thus making it easier for a farmer to grow it.
Capable of growing in any type of soil it can withstand heavy winds and produce seeds within five years after planting.
“A farmer can get four to 20 kg of seeds a year from a five year old tree. After 10 years, a tree will yield 10 – 60 kg in a year and the seed yield will be on the increase as the trees grow older. From my experience, a 25 year-old tree yields a minimum of 300 kg and a maximum of 500 kg of seeds,” says Mr. Rajasekaran.
The trees attract lot of honey bees and bats. While the bees help to pollinate the bats eat the fruits and the seeds scatter all over the area through their droppings.
“My daily job in the morning is to collect the seeds and dry them for a week, after which they are broken open to expose the kernel. The kernel is further dried for 10 days before oil extraction,” he adds.
From one kg of seed kernel about 750 to 800 ml of oil can be extracted and the cost of producing a litre of oil works out to Rs.10.
“I operate the pump only during summer, for about five months in a year to be precise and for that my requirement is 600 ml of oil for an hour every day. Previously while using diesel my requirement was 900 ml for the same duration of time.
In a year I am able to get 75 litres. The surplus oil is sold to other farmers at Rs. 42 a litre. After extracting the oil, the cake is used as manure for crops,” he explains.
According to the farmer there is no rust formation in the engine and it emits little noise during operation. For the last four years he has been using this oil to run his motor and till date seems to have not faced any problem with the engine.
“I find there is no remarkable difference between a punnai oil and diesel run five Hp motor engine. Both pump 750ml of water in a minute. In fact the engine running on the oil emits less smoke unlike the diesel operated one,” he says.
Unlike casuarina or teak, punnai trees are not normally planted by farmers. The few trees found in some places have been growing there for years similar to the palm trees one finds on the rural roadside.
“But the benefits from the tree are quite remarkable in terms of bio energy. It is the job of the state Agriculture University and Government to popularise this tree among farmers and encourage them to plant it.
“If done, in two years or at most in another 10 years we might not face the same power problem we are facing now if all our farmers become aware about this tree he says,” with a smile.
Every day his farm draws several visitors who are eager to know more about the oil and its use for their machines.
For more details interested farmers can contact Mr. C. Rajasekaran, Kandaiyankaadu village, Vettaikaaranirruppu Panchayat, Kivalur Taluk, Nagappattinam District, Mobile: 97510 02370.
If liver has the capacity to regenerate then why does one need to have liver transplantation?
Liver regeneration is a misnomer because the removed liver will not grow back, not the same sort of regeneration as we see in echinoderms such as the Sea Star where the cut off arm grows into a new arm and also the regeneration of limbs in amphibian models.
Liver regeneration is a complex, evolutionarily conserved process. In case of humans, the liver actually hypertrophies by increasing the number of liver cells thereby increasing the size of the liver. It is the division of mature functioning cells of the remnant liver through hyperplastic response instead of recruitment of liver stem cells or progenitor cells.
During this process, the proliferation stops once the liver has attained its original size which is highly regulated and determined by the demands of the organism. Our body knows the size of the liver that it needs to carry out the normal metabolism.
Though liver has the capacity to regenerate, in certain cases liver transplantation is the only way to prolong one’s life. Biliary atresia in children and cirrhosis in adults require a liver transplantation for survival. Cirrhosis is the final phase of chronic liver disease with scarring of the liver and poor liver function.
The most common causes of cirrhosis are hepatitis B or C infection and alcohol abuse along with a few less common causes. Biliary atresia is a blockage in the ducts that carry bile from the liver to the gallbladder. Biliary atresia leads to liver damage which is deadly if not treated.
Living donor liver transplant and cadaverous liver transplant are the liver transplant methods. In living donor liver transplantation, a piece of liver is removed from a living donor and transplanted into a recipient whereas in cadaverous liver transplantation, the liver from brain-dead patients are transplanted into the recipients.
Both the donor and the recipient body send signals to the liver to remodel and grow to its normal size. These events occur so quickly within a week or so and continue to do so over six months to a year. For quicker and successful regeneration both have to be supplied with a lot of extra nutrients after the surgery. Regeneration is required even in cadaverous liver transplantation due to the loss of liver cells from ischaemic injury to the graft.
