On Mahalaya, people throng to the holy river Ganges in order to pay homage to their ancestors and forefathers; which is called ‘Torpon’
Mahalaya remains incomplete without the magical chanting of the scriptural verses from the ‘Chandi Kavya’ that is broadcasted in All India Radio
The magic is induced by the popular Birendra Krishna Bhadra whose voice makes the recitation of the “Chandi Kavya” even more magnificent
Sept 19, 2017: Autumn is the season of the year that sees the Hindus, all geared up to celebrate some of the biggest festivals of India. The festive spirit in the Bengalis all enthused to prepare for the greatest of the festivals, the ‘Durga Puja’.
Mahalaya is the auspicious occasion that marks the beginning of “Devipaksha” and the ending of “Pitripaksha,” and this year it is celebrated on September 19.
Observed exactly a week before the ‘Durga Puja’, Mahalaya is the harbinger of the arrival of Goddess Durga. It is celebrated to invoke the goddess possessing supreme power! The goddess is invited to descend on earth and she is welcomed with devotional songs and holy chants of mantras. On this day, the eye is drawn in the idols of the Goddess by the artisans marking the initiation of “Devipaksha”. Mahalaya arrives and the countdown to the Durga Puja begins!
NewsGram brings to you latest new stories in India.
The day of Mahalaya bears supreme significance to the Bengalis. The day is immensely important because on this day people throng to the holy river Ganges in order to pay homage to their ancestors and forefathers. Clad in white dhotis, people offer prayers and take dips in the river while praying for their demised dear ones. The ritual is popular as “Torpon”.
As per Hindu myth, on “Devipaksha”, the Gods and the Goddesses began their preparations to celebrate “Mahamaya” or Goddess Durga, who was brought upon by the trinity- Brahma, Vishnu, and Maheshwara; to annihilate the fierce demon king named Mahishasura. The captivating story of the Goddess defeating the demon got popularized with the goddess being revered as “Durgatinashini” or the one who banishes all the evils and miseries of the world. The victory of the Goddess is celebrated as ‘Durga Puja’.

Mahalaya remains incomplete without the magical chanting of the scriptural verses from the ‘Chandi Kavya’ that is broadcasted at dawn in All India Radio in the form of a marvelous audio montage enthralling the souls of the Bengalis. Presented with wonderful devotional music, acoustic drama, and classical songs- the program is also translated to Hindi and played for the whole pan-Indian listeners.
The program is inseparable from Mahalaya and has been going on for over six decades till date. The magic is induced by the popular Birendra Krishna Bhadra whose voice makes the recitation of the “Chandi Kavya” even more magnificent! He has been a legend and the dawn of Mahalaya turns insipid without the reverberating and enchanting voice of the legendary man.
Mahalaya will keep spreading the magic and setting the vigor of the greatest festival of the Bengalis- the Durga Puja, to worship the supreme Goddess, eternally.
The availability of cheap natural gas and greater energy efficiency has reduced demand for nuclear energy in recent years
Nuclear power is clean, safe and better for the environment than some alternative energy sources
Industry experts say that women who work in nuclear power can be powerful advocates for nuclear
San Francisco, August 26, 2017: Kristin Zaitz is confident that her nuclear power plant is safe.
Zaitz, an engineering manager, was at Diablo Canyon Power Plant during both her pregnancies and has scuba dived to inspect the plant, which hugs the California coast. Zaitz wears a pendant with a tiny bit of uranium inside, an item that tends to invite questions.
“We all have our perceptions of nuclear,” Zaitz said.
In a few years, Diablo Canyon will close, part of a trend nationwide. The availability of cheap natural gas and greater energy efficiency has reduced demand for nuclear energy in recent years. Add to that ongoing concerns about public safety, such as those raised by memories of disasters at nuclear power plants in Fukushima, Japan, Chernobyl in Ukraine (then part of the Soviet Union) and Three Mile Island in the United States.
Nuclear is ‘cleaner’ than fossil fuels
Supporters of nuclear energy say that when a reactor-based generating station closes, not enough wind and solar power is available to make up the difference. They lament that energy companies tend to turn instead to fossil fuels — coal and natural gas — which produce environmentally harmful emissions.
Zaitz and her co-worker Heather Matteson, a reactor operator, started Mothers for Nuclear, their effort to get the word out that nuclear power is clean, safe and better for the environment than some alternative energy sources.
“I went into the plant very skeptical of nuclear and being scared of it,” said Matteson. “It took me six to seven years to really feel like this is something good for the environment. I don’t want people to take six to seven years to make that decision. We don’t have that long.”
Matteson, too, wears the uranium necklace as a conversation starter. “Nuclear is fun,” she said. Is there any radiation emitted by the pendant? “There’s slightly more than from a banana,” she conceded.
Industry experts say that women who work in nuclear power can be powerful advocates for nuclear. They can help change attitudes of other women who tend to be more skeptical than men about nuclear energy’s benefits.
At the recent U.S. Women in Nuclear conference in San Francisco, women working in the industry talked about how more should be done to make nuclear power’s case to the public, and how they may be the best suited to do it.
“As mothers, I think we also have an important role to play in letting the public know that we support nuclear for the future, for our children,” said Matteson. “And we don’t know other mothers supporting nuclear power in a vocal way. We thought there was a gap to fill.”
Young women say they look at careers in this industry because they are socially minded.
‘Do something good for the world’
“I went into this wanting to do something good for the world,” Lenka Kollar, business strategy director at NuScale, a firm in Oregon that designs and markets small modular reactors. “Wanting to bring power to people. There are still more than a billion people in the world who don’t have electricity.”
Critics of nuclear energy say it doesn’t matter who is promoting it.
“Using mothers’ voices to argue for a technology that is fundamentally dangerous and that has been demonstrated by disasters like Fukushima to be not safe for the communities that surround the power plants or even cities that are hundreds of miles away is disingenuous,” said Kendra Klein, a staff scientist with Friends of the Earth, an environmental group.
While the future of nuclear power in the United States may be uncertain, the women here say they have a positive story to tell. (VOA)
The new self-powered version promises to be inexpensive and easy to apply to existing windows
The smart window controls the transmission of visible light and infrared heat into the building
The researchers chose the material because its chemical structure could be modified to absorb a narrow range of wavelengths
New York, July 2, 2017: By applying a new solar cell technology, researchers have developed a self-powered version of smart windows that could help save energy costs. Smart windows equipped with controllable glazing can augment lighting, cooling and heating systems by varying their tint, saving up to 40 percent in an average building’s energy costs. But these conventional smart windows require power for operation, so they are relatively complicated to install in existing buildings.
The new self-powered version promises to be inexpensive and easy to apply to existing windows, the researchers said.
This system features solar cells that selectively absorb near-ultraviolet (near-UV) light, so the new windows are completely self-powered.
“Sunlight is a mixture of electromagnetic radiation made up of near-UV rays, visible light, and infrared energy, or heat,” said Yueh-Lin (Lynn) Loo, Professor at Princeton University, New Jersey, US.
“We wanted the smart window to dynamically control the amount of natural light and heat that can come inside, saving on energy cost and making the space more comfortable,” she added.
The smart window controls the transmission of visible light and infrared heat into the building, while the new type of solar cell uses near-UV light to power the system.
“This new technology is actually smart management of the entire spectrum of sunlight,” Loo said.
In the paper published in Nature Energy, the researchers described how they used organic semiconductors — contorted hexabenzocoronene (cHBC) derivatives — for constructing the solar cells.
The researchers chose the material because its chemical structure could be modified to absorb a narrow range of wavelengths — in this case, near-UV light.
“Using near-UV light to power these windows means that the solar cells can be transparent and occupy the same footprint of the window without competing for the same spectral range or imposing aesthetic and design constraints,” Loo added.
The researchers explained that the near-UV solar cell technology can also power internet-of-things sensors and other low-power consumer products.
“It does not generate enough power for a car, but it can provide auxiliary power for smaller devices, for example, a fan to cool the car while it’s parked in the hot sun,” Loo said. (IANS)
