Expressive message

 

A university professor wrote an expressive message to his students at the doctorate  masters and bachelors levels in South Africa.  The message

Collapsing any nation does not require use of atomic bombs or the use of long range missiles. It only requires lowering the quality of education and allowing cheating in the examinations by the students.

The patient dies in the hands of such doctors.  And buildings collapse in the hands of such engineers. And money is lost in the hands of such accountants. And humanity dies in the hands of such religious scholars. And justice is lost in the hands of such judges.

The collapse of education is the collapse of the nation.

 

The freshly brewed aroma of a letter

In a bygone era young women would spray a little perfume on their letters to their beaus. Nowadays of course even getting a handwritten letter in the poet is a rarity.

But India Post is making it possible to send letters that carry the fragrance of something a large part of India loves deeply  on Sunday April 23 the Department of Posts will release a ‘ coffee stamp ‘ at the General Post Office Bengaluru.  The stamps have been printed at the India Security Press   Nashik.

It will last long

The technology involves spraying or embossing the stamps with fine coffee granules that will retain the aroma for a long time  said Charles Lobo,  Chief Post Master General Karnataka Circle.  “ Only on the day of the release will we know the colour  texture and design “

The stamp will be released by Minister of State for Communications Manoj Sinha and Union Minister for Commerce and Industry Nirmala Sitharaman with officials of the Postal Department and Coffee Board.  “ I ‘m very excited about the coffee stamp “ said Ms. Sitharaman.  “ It is not just about philatelic interest but also about the appreciation of coffee.  It’s a collector’s version priced at Rs  100.  Coffee deserves a premium price  we should not underprice it”.

One lakh stamps will be ready for sale to collectors.  The stamp first day cover miniature sheets and information brochures will be available at the Philately Bureau  Bangalore General Post Office and all other head post offices.

Bhutan first introduced the concept of aromatic stamps in 1973.  New Zealand  Thailand and Switzerland among others joined in later.  Brazil has issued coffee and burnt wood scented stamps and China has done fruits and sweet and sour pork.

India introduced its first aromatic stamp in 2006 with a Rs 15 sandlewood scented stamp.  Thirty lakh of these sold out within two weeks.  In 2007 there were rose scented  stamps  in four varieties of the flower Jawahar  Neelam  Delhi princess and Bhim  at Rs 5 each and a jasmine fragrance in 2008

A great leap in science

The world of gadgets is ever evolving and everyday day there emerges  a new concept to improve existing technology. Working on increasing the speed of electronic devices with the help of photonics technology is Dasari Venkatakrishna Rao  who is pursuing PhD in material chemistry from university of Hyderabad.  He has been selected for Lindue Nobel laureates 2017 an annual scientific conference that brings together Nobel laureates and young scientists to discuss important issues in that field. It will be held in Germany in June.  ‘ I ‘m happy that I was selected to present my studies at such a prestigious place. I am excited about meeting people who are working on similar technology there and getting feed back about my work so far.  The technology I am working on is relatively new and hence not many are aware of the advantages of using light instead of electrons in electric devices’ says Dasari.

About his study Dasari says “ the speed of light is much faster that the speed of electrons. In the same case if you want to send a signal from one regime to another regime  you need a medium to pass the signal. Unlike electronics light may not need any medium to send a signal to two separate extremes. We are working on creating micro lasers and modulators which can fit into photonic devices. Scientists are already working on creating photonic chips in western countries but no one is working on this subject in India’

While growing up Dasari wanted to be a doctor but his parents couldn’t afford it.  “ My father worked as a security guard and my mother was a daily wage worker. When I was in class VIII I realized that I was good at chemistry and decided to pursue a career in it. It was while I was graduating that I chose photonics as my subject of research. Soon I ‘ll actually becalled Dr. venkatakrishnarao” says the 27 year old from Ongole with a laugh.

Dasari is a dedicated student and spends most of his time in the lab either studying or experimenting under the guidance of his supervisor Professor Rajadurai Chandrasekar  whom he considers his idol.  “ I am an atheist. I think man has the power of defining his own destiny.  Professor Chandrasekar is very knowledgeable and helpful.  He inspires me to put in more than 100 percent in my work. I idolize Dr A P J Adbul Kalam and Dr B R Ambedkar who also came from small towns and made it big “ he concludes.

Young inventors

top-10-qr-barcode-ah-1

A group of five students from the city invented a watch that scans bar codes to calculate bills easily. A group of students observed that during rush hours the small time retailers near their school often struggled to calculate bills. This set the group of young students from Abhaya School in the city, thinking of a way to help them. It soon paved way for the creation of a wearable device called V watch.  V watch helps retailers scan bar codes and calculate bills easily. It is no surprise competition conducted by Manipal University.

Under the mentorship of teacher Ameer Khan four class X students and a class IX students  joined hands to put their creative and innovative minds together to make the V watch a reality. The Teenovators competition is open to Indian students of class IX to class XII.  “ The group of students from the Abhaya School were selected for their love for innovation and science. After the basic registration process the whole screening process consisted of four rounds before the finale” says Ameer.

“ when we sat together to think what can be done to help the local vendors the idea to create V watch didn’t strike us. It was more of an afterthought, when we wre competing at Teenovators and our mentor over there Raunak helped us rethink our strategy” shares Geethika Arcot a member of the team. She further adds “ we quickly realized the potential of a wearable device and worked towards it.  We made the software for the watch which enables it to scan the bar code and generate bills and also a mobile application through which the retailers can operate the watch.”  For the team it was a great opportunity to learn feels Siddhanth another teammate. “ We were one of the two schools from Hyderabad to compete at the national level. We were selected  after a thorough screening from around 30 schools in the city.  We got to learn a lot from the other teams and mentors at the event “ he says.

Delving into their plans further about their creation being available for common people Shane Stanley a team member elaborates “ Raunak is keen to invest in V watch and plans to float a company soon. We all will be the  share holders until we reach a suitable age to take charges.”

Sitting for long can age women faster

Elderly women who sit for more than 10 hours a day with low physical activity have cells that are biologically older by eight years compard to women who are less sedentary a new study has found.

Researchers from University of California found that women who have a sedentary lifestyle have cells that are biologically older and invite cardiovascular diseases and diabetes as compared to women who are active and exercise regularly.

“ Our study found cells age faster with a sedentary lifestyle.  Chronological age doesn’t always match biological age” said lead researcher Aladdin Shadyab from UC.  Elderly women with less than 40 minutes of moderate-to-vigorous physical activity per day and who remain sedentary for more than 10 hours per day have shorter telomeres   tiny caps found on the ends of DNA strands that protect chromosomes from deterioration and progressively shorten with age. As a cell ages its telomeres naturally shorten and fray and make a body prone to cardiovascular disease diabetes and major cancers.

‘ We found that women who sat longer did not have shorter telomere length if they exercised for at least 30 minutes a day the national recommended guideline’ said Shadyab in a study published in the American Journal of Epidemiology.”

What is a prayer?

images

Prayer does not just happen when we kneel or put hands together and focus and expect things from God.

Instead…………

Thinking positive and wishing good for others

That’s prayer2432548258_073f8689c6

When you hug a friend

That’s prayer

When you cook something to nourish family and friends

That’s prayer

When we send off our near and dear ones and say “ drive safely’  or “ be safe ‘

That’s prayer

When you are helping someone in need by giving your time and energy  You are praying.

Prayer is A vibration  A feeling  A thought.

Prayer is the voice of love  friendship and genuine relationships.
