Why Airplane Windows Have Tiny Holes….

My friends laugh at me when I ask for a window seat. You’re an airline pilot, they say. You have the window seat all the time.

True enough. But the cockpit, well, that’s work. As a passenger I’m actually free to enjoy the experience—to listen to music or a long-postponed podcast while gazing out at the world below, to remember that it’s still a wonder to look down, not up, at clouds. The window seat is like the best table in a café on a busy street, except that instead of people-watching, entire cities, oceans, and mountain ranges parade past.

Still, every once in a while something interferes with that view. Maybe it’s the forehead smudges left by your seat’s previous occupant. Or the little hole that appears in the lower portion of a typical airliner window.

Hole in the window? The little one, near the bottom, that you perhaps only notice when a hollowed-out snowflake of frost forms near it. This tiny hole is called a breather hole or a bleed hole, and it serves an important safety function.

If you look closely at a typical passenger cabin window, you’ll see three panes, typically made of acrylic materials. The purpose of the innermost pane—sometimes called the scratch pane, but I like to call it the smudge pane—is merely to protect the next one.

The middle pane (with the breather hole in it) and the outer pane are more important. Generally speaking, as an aircraft climbs, the air pressure drops in both the cabin and the outside air—but it drops much more outside, as the aircraft’s pressurization system keeps the cabin pressure at a comfortable and safe level. This means that the pressure inside the aircraft during flight is typically much greater than the pressure outside.

The outer two cabin windows are designed to contain this difference in pressure between the cabin and the sky. Both the middle and the outer panes are strong enough to withstand the difference on their own, but under normal circumstances it’s the outer pane that bears this pressure—thanks to the breather hole.

As Marlowe Moncur, director of technology 
for GKN Aerospace, a leading passenger cabin window manufacturer, put it to me via email: “[T]he purpose of the small bleed hole in the [middle] pane is to allow pressure to equilibrate between the passenger cabin and the air gap between the panes, so that the cabin pressure during flight is applied to only the outer pane.”

In the extraordinarily unlikely event that the outer pane fails, the middle pane takes over. And yes, in that case, there would be a small leak of air through the breather hole—but nothing the aircraft’s pressurization system couldn’t easily cope with.

Bret Jensen, an aerospace engineering guru at Boeing Commercial Airplanes, told me about a separate but related function of the hole: to release moisture from the air gap and stop (most) fog or frost from forming on the window. So when you’re looking out at the clouds and planetary wonders crossing below you, take a moment to give thanks for the breather hole.

There’s still the matter of that small but lovely pattern of frost that can form near the breather hole on a long flight. At cruising altitude the temperature of the outside air can be minus 70 degrees Fahrenheit. The frost, according to Moncur, “is caused by condensation of water when cabin air contacts the cold window surface.”

But what causes that telltale frost pattern? The physics behind it are an interesting question, he says. “The circular pattern must be a function of window surface temperature, humidity of the cabin air and flow rate through the bleed hole.”

“How IIT Kharagpur Researchers are ‘Leading a Green Revolution’ …”

Indrani Roy/Rediff.com traces how researchers at IIT-Kharagpur have managed to turn barren land of surrounding villages to multi-crop farmland

Prof PBS Bhadoria speaks to farmers

Dr P B S Bhadoria of IIT-Kharagpur speaks to the farmers of Khentia village in Kharagpur.

Jagannath Das, a farmer in his late 40s is surveying a farmland at Khentia village in Kharagpur.

The summer sun is merciless.

With the mercury at cruel 42 degrees, Das is sweating profusely but is smiling a happy smile.

“Five years ago, we could not imagine producing even a handful of paddy in this barren land of Khentia.

“But thanks to IIT Kharagpur professors, we can now grow paddy for our own consumption and can also farm soyabean, sweet corn, sesame, peanut etc,” Das tells  rediff.com.

A group of researchers at the IIT-K, which is about 10 kms from the Khentia village, have ‘adopted’ 14 acres of erstwhile barren land and turned it productive.

The farmers of Khentia who are working in tandem with the IIT team now can not only grow their own food but can also nurture the dream of selling the extra produce directly to retailers bypassing the greedy middlemen.

“We are really happy to be involved in this project. We can now grow our food and can also make money by selling the cash crops like sweet corn, peanut, soyabean that we have started growing in our land,” says 70-year-old Gora Das.

According to the IIT team, Das is one of the most hardworking farmers of Khentia.

“During the initial months of land preparation, we saw him working round the clock de-weeding the fields and tilling it from dawn to dusk,” says Abhishek Singhania, a young member of the IIT team.

Baby steps

Vermicomposting

The IIT team helped the farmer prepare a special low-cost vermicompost.

“Our biggest challenge was to prepare this land, which has been lying unused for years, suitable for cultivation,” says P B S Bhadoria, an IIT faculty member who is leading this initiative along with 29 other teachers.

“The project was conceived a year back when our director Partha P Chakrabarti approached the central government and expressed his intent to do something on food security.

“The central government lauded the idea and agreed to support the move,” Bhadoria says.

The harvesting machine

Farmer Jagannath Das demonstrates the harvesting machine.

Thereafter, 14 acres of land from 14 farmers of Khentia was chosen for the Rs 16-crore (Rs 160-million) project.

The field work for the project started in October 2014.

The project involves three departments of IIT-Kharagpur — agriculture and food technology, biotechnology and industrial engineering.

At present, there are about 30 experts assisting Bhadoria.

The total span of the project is three years.

Convincing the farmers wasn’t easy

“Convincing the farmers was a daunting task. Initially, the farmers were not ready to hand over their land to the IIT people. There was some political tension as well.

“Farmers with differing political views tried to create complications,” Bhadoria tellsrediff.com.

“But these problems were sorted out after long discussions and we got the farmers’ nod to go ahead with our experiments on these barren lands,” he adds.

“Perhaps, the farmers too did not like the fact that the land was lying unproductive for years,” Bhadoria says.

How the land was prepared

“Small adjacent pieces of land belonging to a single farmer were merged,” says Dilip Kumar Swain, associate professor, agricultural and food engineering department.

“Primary and secondary tillage was done by tractor-driven plough followed by levelling in November,” he adds.

“We did soil testing, which helped us determine the amount of fertiliser needed.”

“Earlier, the farmer would randomly use chemical fertiliser which often affected the land’s fertility.

“However, the 14 farmers who have partnered with us, now know the importance of soil testing before applying chemical fertiliser”, Swain says.

‘We gave importance to partnership’

“We wanted to bring the farmers into the project’s fold right from the beginning,” Bhadoria tells rediff.com.

“It had to be a collaborative project,” he adds.

“The understanding is, for one year, we will provide the farmers technical assistance, machines while they will provide free labour,” Swain tells rediff.com.

Peanut

Apart from paddy, the farmers of Khentia are also growing peanuts.

“And after a year, we plan to hand over the entire project to the farmers,” he adds.

“This way, the farmers will attain self sufficiency,” Swain says.

The farmers have been asked to form a cooperative wherein they will distribute the produce of the land according to their percentage of ownership.

“While this creates a bonding among them, it also instills a sense of competitiveness among the tillers of the soil,” Swain says.

Irrigation was the key

The IIT team developed an irrigation facility in December by:

  • installing a deep tube well in the area;
  • constructing a pump house and
  • by providing fencing protection of the cropped land

As part of the irrigation system development, a pond in the area was renovated to store rain water and grow fish. The pond was plastered with bentonite clay to check seepage.

According to Singhania, “The pond now takes care of the irrigation of the farmland to a large extent,” Singhania says.

How production was enhanced

The farmers were given training on the production technology of System of Rice Intensification.

This technology saves 80-90 per cent seed and 40-50 per cent water.

The farmers were introduced to organic rice production technology.

They were taught to supply essential nutrients to their crops by using organic manure.

Trainings were given on effective and proper use of bio-pesticides.

“With the help of these technologies, farmers of Khentia could now produce as much as two tonnes of rice per acre,” Swain tells rediff.com.

“Moreover, they were able to minimise the loss of crops occurring out of unseasonal rains this year,” says Bhadoria.

Agrees farmer Swapan Das.

“Apart from growing rice in abundance, we doubled the production of other crops as well. It’s a miracle,” Das tells rediff.com.

Initially, the farmers of Khentia wanted to grow rice only.

However, after studying the land, its water demand and fertility, the IIT team introduced high value, soil restoring crops like sweet corn, sesame, soybean and peanut.

A low cost vermicompost is of great help

The IIT team helped the farmer prepare a special low-cost vermicompost by rotting cow dung, water hyacinth, farm wastes with 2.5-3 kg of eisenia foetida, a special species of earthworm in each bed of size 1.8mx1.2mx1m.

Each bed is expected to produce 100 kg of vermicompost in a single cycle of 60 days.

“Earlier, the farmers would burn the farm waste, causing pollution,” Singhania tells rediff.com

Soyabean cultivation

An IIT team member shows a soyabean fruit.

“We taught them to convert the farm wastes into an environment-friendly vermicompost which will cause any pollution but will give them a tool to practice organic farming,” he adds.

Singhania has his hands full making a sustainable farming-cum-marketing model so that once the IIT team leaves, the farmers can do everything on their own.

“We want to make them self-sufficient. They should grow their food, sell the extra produce to the retailers sans the middlemen and improve the condition of their land for sustenance,” Singhania says.

Future looks bright

The IIT-Kharagpur initiative has drawn accolades from the Union Human Resource Development Ministry, which has awarded the institute a grant of Rs 26 crore (Rs 260 million) to replicate the experiment in nine other villages.

The project has also been made a part of the Narendra Modi government’s Unnat Bharat Abhiyan.

The IIT has adopted surrounding villages of Polisa, Chakmakarampur, Paparara I and II, Sankua, Lachamapur, Kaliara-1 and 2 and Changual to replicate the experiment there.

IIT-Kharagpur director Partha P Chakrabarti couldn’t have been happier.

“To focus on food security is an absolute must and we just can’t afford to ignore agriculture,” he tells rediff.com.

IIT Kharagpur director

IIT Kharagpur director Partha P Chakrabarti.

“We often see farmers falling preys to advertisements and other marketing gimmicks,” says Chakrabarti.

“They have very little knowledge of technicalities of farming, quality of fertilisers and pesticides and end up paying for only those that are the most advertised.

“But as technical experts, we felt we should impart them the knowledge about farming.

“Since Kharagpur is surrounded by villages, we thought of starting the experiment here. “We are happy that our years’ of research in agriculture laboratories has borne fruit”, the director says.

Other Indian states like Bihar have approached the institute to start similar projects there.

What Our Kids Missing Today ….!!!

Nostalgia: Children Having a Grand Ol’ Time

Remember how children used to enjoy themselves before the invention of the Internet and the Smartphone? Before television had dozens of channels, playing cartoons 24/7? Nowadays, the computer becomes our children’s best friend, and sometimes they spend too much time on it. It’s always nice to reminisce about the time when we were young, and that to have fun, we would leave the house to see and explore the world. These 19 vintage photos from around the world depict a time where staying inside was a punishment.

Message for the Day…” One Must Understand and Realise the Real Purpose of Human Life …”

Students of today are blind to the goal of life. Some students do not even feel the pain of not knowing the purpose of life. Only one in a million or a crore strives to realise the essence of life. This striving is the stepping stone for the realisation of the purpose of life. Many people feel that the acquisition of food, clothing, shelter, wealth, conveniences, and comforts constitute the very purpose of life. Life remains a tragedy as long as one labours under this kind of delusion. The day one realises the purpose of life, one undergoes a total transformation, from vedana (agony) to nirvedana (freedom from pain). When one becomes conscious   of light, acquires wisdom and realises the meaning of existence, one is transported from agony to ecstasy. Every bit of learning should be based on the foundation of ethical, righteous and spiritual principles. Education that is not founded on these will flounder to the ground and become useless.

Sathya Sai Baba

படித்து ரசித்தது …” இது ஒரு சத்திரம்தானே ….” !!!

உத்தமர்களின் வாய்ச்சொல், சத்திய மார்க்கத்தையே உரைக்கும்; அதன் வழி நடந்தால் நல்லதையே அடைவோம்.
அரசர் ஒருவர், தேவேந்திரனை நோக்கி, பல காலம் தவம் இருந்தார். அவருடைய தவத்திற்கு இரங்கிய தேவேந்திரன், கற்பக மரத்தையே அரசருக்குக் கொடுத்து விட்டார்.
கேட்டதை மட்டுமல்ல, நினைத்ததை எல்லாம் கொடுக்கக் கூடிய கற்பக மரம் கிடைத்ததும், தலை கால் புரியாமல் மனம் போனபடி வாழ்ந்தார் அரசர்.
அரசரைப் பற்றி அறிந்த தத்தாத்திரேயர், ‘தவசீலரான இந்த அரசன் கற்பக விருட்சத்தை பெற்றதும், கடைந்தேறும் வழியைப் பற்றி எண்ணாது, உலக இச்சைகளில் உழன்று கொண்டிருக்கிறானே… இவனுக்கு நல்லறிவு புகட்ட வேண்டும்…’ என நினைத்தார்.
ஒரு நாள், அரண்மனைக்குள் நுழைந்த தத்தாத்திரேயர், ‘விடு விடு’ வென்று நடந்து போய், அரசருக்கு மட்டுமே உரித்தான உயர் ரக இருக்கையில் அமர்ந்தார்.
சேவகர்களால் அவரைத் தடுக்க முடியவில்லை.
தகவல் அறிந்த அரசர் வேகமாக வந்து பார்த்தார். ‘யார் நீ… என்ன தைரியம் இருந்தால், என் இருக்கையில் அமர்வாய்… போ வெளியே…’ என்றார்.
‘மன்னா… கோபப்படாதே… இந்தச் சத்திரத்தில், நீ தங்கி இருப்பதைப் போலத் தான், நானும் தங்கியிருக்கிறேன். இதற்குப் போய் கோபப்படுகிறாயே…’ என்றார்.
‘இது ஒண்ணும் சத்திரமல்ல; என் அரண்மனை. போ வெளியே…’ என்று கோபத்துடன் கூறினார்.
‘ஆயிரக்கணக்கான ஆண்டுகளாக, இங்கு வசித்து வருகிறாயோ…’ என்றார் தத்தாத்திரேயர்.
‘இல்லை… நான் பிறந்தது முதல், இங்கு தான் வாழ்ந்து வருகிறேன்…’ என்று மன்னர் சொல்ல, ‘உனக்கு முன் இங்கு இருந்தது யார்?’ எனக் கேட்டார் தத்தாத்திரேயர்.
மன்னர் பொறுமை இழந்து, ‘எனக்கு முன் என் தந்தை; அவருக்கு முன், என் தாத்தா; அதற்கு முன் என் கொள்ளுத் தாத்தா… இப்படிப் பல பேர் இங்கு தான் இருந்திருக்கின்றனர்…’ என்றார்.

ஆக, இங்கு யாருமே நிரந்தரமாகத் தங்கவில்லை. ஒருவர் வர, ஒருவர் போக என்று தான் இருந்துள்ளனர். அப்படி என்றால், இது சத்திரம் தானே? இதைப் போய் அரண்மனை என்கிறாயே… அதுவும் உன் அரண்மனை என்கிறாய். இது எப்படி?” என, அமைதியாக கேட்டார் தத்தாத்ரேயர்.
மன்னருக்கு, ‘சுருக்’கென்றது. தத்தாத்திரேயரின் திருவடிகளில் விழுந்து வணங்கி, உபதேசம் பெற்று உயர்ந்தார் அரசர்.
நல்லதையே கேட்போம்; நமக்கது உதவும்!

” The World’s Most Brazenly Hidden Bird — the Common Potoo”

 

The incredible common potoo isn’t much to look at — so much so that you’ll struggle to see it at all! In a bold display of camouflage and mimicry, this bird pretends to be a broken tree branch. To do so, it poses absolutely still, bravely evading predators in plain view of them. The potoo in this video is particularly fearless — switch the quality up to HD and watch to find out why she’s so determined not to be scared away from her perch.

Although you might not see them, the common potoo is, indeed, common in at least parts of its range. This rage extends from Nicaragua in Central America, south to Argentina. Six other species of potoo are known of, all generally similar in appearance and all performing the same posturing cryptic behaviour. Potoos have large eyes and a huge mouth — features they share with the closely related nightjars.

As mentioned in the video, potoos squint their eyes in order to not expose their bright yellow irises and give the game away while keeping track of potential predators. Fortunately for them, potoos have an amazing, subtle adaptation — slight notches in the eyelids, which are presumed to enable them to see even when their eyes are apparently closed.

Again like the nightjars, the eyes of the potoo are highly reflective to artificial light. Being incredibly cryptic, their eye-shine means that a night time stalk with a torch light is the best way to locate them.

If you’ve watched the video by now, then you’ll know that this potoo has a young chick. Potoos lay just a single egg, and most commonly do so in the slight bowl of a tree branch or broken stump like the one in the video. Potoos form monogamous pairs, sharing responsibility for raising the young. Some evidence suggests that, during the day, egg incubation and chick protection duties are performed by the males of breeding pairs, with the females taking the night shift.

However, over a 36-hour period, there were no ‘shift-changes’ in this potoo family, making for one no-doubt exhausted parent who we have arbitrarily (males and females have similar colouring) designated as the female!

ஆனால் இந்தக் காலத்தில் ஓரிரு குழந்தைகள் மட்டுமே உள்ள நிலையில் பெற்றோர்கள் தங்கள்குழந்தைகளுக்கு மிக நல்ல வாழ்க்கை அமைத்துக் கொடுக்க வேண்டும் என்பதில் குறியாகஇருக்கிறார்கள். அதில் தவறில்லை. ஆனால் தான் பட்ட கஷ்டங்கள் எதையும் தங்கள் குழந்தைகள்படக்கூடாது என்று நினைக்கும் போது பாசமிகுதியால் அவர்கள் அந்தக் கஷ்டங்கள் தந்த பாடங்களின்பயனைத் தங்கள் பிள்ளைகளுக்கு அளிக்கத் தவறி விடுகிறார்கள். அதற்காக “நான் அந்தக் காலம்பள்ளிக்கூடம் செல்ல பல மைல்கள் நடந்தேன். அதனால் நீயும் நட” என்று பெற்றோர்கள் சொல்லவேண்டும் என்று சொல்லவில்லை. வசதிகளும், வாய்ப்புகளும் பெருகி உள்ள இந்தக் காலத்தில்அப்படிச் சொல்வது அபத்தமாகத் தான் இருக்கும்.

இன்றைய நவீன வசதி வாய்ப்புகளின் பலனை பிள்ளைகளுக்கு அளிப்பது அவசியமே. தேவையேஇல்லாத கஷ்டங்களை பிள்ளைகள் படத் தேவையில்லைதான். ஆனால் ‘எந்தக் கஷ்டமும், எந்தக்கசப்பான அனுபவமும் என் பிள்ளை படக்கூடாது’ என்று நினைப்பது அந்தப் பிள்ளையின்உண்மையான வளர்ச்சியைக் குலைக்கும் செயலே ஆகும்.

வாழ்க்கையில் சில கஷ்டங்களும், சில கசப்பான அனுபவங்களும் மனிதனுக்குஅவசியமானவையே. அவற்றில் வாழ்ந்து தேர்ச்சி அடையும் போது தான் அவன் வலிமைஅடைகிறான். அவற்றிலிருந்து பாதுகாப்பளிப்பதாகப் பெற்றோர் நினைப்பது அவனுக்குவாழ்க்கையையே மறுப்பது போலத் தான். சில கஷ்டங்கள் பிள்ளைகள் படும் போதுபெற்றோர்களுக்கு மனம் வருத்தமாக இருக்கலாம். ஆனால் கஷ்டங்களே இல்லாமல் இருப்பதுவாழ்க்கை அல்ல, வாழ்க்கையின் அர்த்தமும் அல்ல, அது சாத்தியமும் அல்ல

Message For the Day…” Your Soul [Divine Self ] is the Real ‘You’ ….”

The human body is a cover, a receptacle for the Atma. Elements like water and wind are intimately bound up with the body. Therefore, theAtma Principle, which is the core, is not cognised. People have lost awareness of this Principle, which is Truth. The Atma is in the body, but not of it. The Atma Principle, though active in the body, does not belong to the body. The ability of the eyes to see and the ears to hear are given by the Atma. The eyes and ears are sustained by the Omni-Consciousness, the Divine Principle. Your Soul (Divine Self) is the real ‘You’, the Will (Sankalpa). The elements (ether, wind, fire, water, and earth) that constitute the cosmos operate only as prompted by the supreme wisdom, which energizes them. The entire world of living beings – both fixed and moving are sustained by supreme wisdom. That supreme wisdom is Atma, the Brahman and the visible, objective world.

Brilliant Video shot From IAF Jaguar Plane…!!!

 

How difficult is it to film a running car sitting in another car? Pretty difficult. But this video mission has crossed all levels of precision and perfection by capturing the launch and the flight of India’s nuclear-capable sub sonic cruise missile called Nirbhay. The missile is being developed by India’s DRDO with features like wing development and a turbofan engine. It carries either conventional or a nuclear payload while flying to the target.

This video uploaded by Anantha Krishnan M. is from the last successful test and is shot from an IAF Jaguar plane. We salute the pilot and the camera person for a brilliant footage!

Result of Team Work and Planning…100 year old Tree Moved and Transplanted in another place…!!!

 

The Ghirardi Compton Oak has been a piece of League City’s history for over 100 years. The tree stands 56 feet tall, has a canopy that is over 100 feet wide, and is 135 inches around. It also weighs an incredible 518,000 pounds. A county road widening project put the future of the Ghirardi Oak in jeopardy. Council voted to use park dedication funds to hire Hess Landscaping Construction to move the majestic oak. A project that took them just under a month to complete. Watch the incredible process from start to finish in this video.
