On March 14, 1931 – exactly eighty years ago – the police had to be summoned to the Majestic cinema hall in Mumbai (then Bombay). The reason for the feared stampede was the uncontrollable response of movie-goers to the first Indian talkie, Alam Ara.
Celebrated by a Google Doodle on the homepage of the search engine in India to commemorate the arrival of sound to Indian cinema, Alam Ara also included the first song in Hindi films – setting off an endearing and enduring tradition. The song, De de khuda ke naam par, was performed on screen by actor Wazir Mohammed Khan – this, of course, was before the days of lip-syncing to playback tracks. The film, in fact, had seven songs, scored by Ferozshah M. Mistru and B. Irani.
The tragedy, however, is that the film may be lost forever. In 2008, an Information and Broadcasting ministry official revealed that no prints are now available with the National Archives of India. The last existing prints were destroyed in a fire at Pune’s National Film Archives in 2003. A search was conducted across the country but no print of Alam Ara could be found.
Here’s the Google Doodle giving a tribute to Alam Ara.
World Kidney Day is celebrated on 10th March this year.
Kidney diseases are increasing very rapidly to epidemic proportions worldwide. In order to increase public awareness about kidney diseases, World Kidney Day (WKD) is observed on the second Thursday of March every year. This year, it falls on 10th March
Children suffering from kidney diseases have been finding it difficult to get donors unlike adult kidney patients who require transplants. Unwillingness on the part of the parents to accept the child’s condition and their failure to report it early enough are among the main reasons, say nephrologists.
On the occasion of World Kidney Day, consultant nephrologist at Deenanath Mangeshkar Hospital, Dr Tushar Dighe, said that of the approximate 100 cases of kidney diseases that are reported in a month, almost 10% constitute paediatric kidney diseases.
This trend has seen a rise in the last five years, although there is no adequate data on the prevalence of kidney diseases among children. It is estimated that in Pune alone, around 4,000 patients with kidney damage requiring transplants are detected every year.
Vitamin D deficiency has been shown to alter lung structure and function in a new study in young mice.
The new study, conducted by researchers in Australia, offers the first concrete evidence linking vitamin D deficiency with deficits in lung function and altered lung structure.
“The results of this study clearly demonstrate that vitamin D deficiency alters lung growth, resulting in lower lung volume and decrements in lung function,” said Graeme Zosky, a research fellow at the Telethon Institute for Child Health Research in Subiaco, Australia.
“This is the first direct mechanistic evidence showing that vitamin D deficiency alters lung development, which may explain the association between obstructive lung disease and levels of vitamin D.”
To conduct their study, the researchers used a mouse model of vitamin D deficiency and evaluated lung responses of two-week-old mice, comparing them to control mice without vitamin D deficiency to determine what, if any, effects the deficiency may have caused in the growth, structure or function of the lungs.
A microcontroller (sometimes abbreviated µC, uC or MCU) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications.
Pins 1-8: Port 1 Each of these pins can be configured as an input or an output.
Pin 9: RST A logic one on this pin disables the microcontroller and clears the contents of most registers. In other words, the positive voltage on this pin resets the microcontroller. By applying logic zero to this pin, the program starts execution from the beginning.
Pins10-17: Port 3 Similar to port 1, each of these pins can serve as general input or output. Besides, all of them have alternative functions:
Pin 10: RXD Serial asynchronous communication input or Serial synchronous communication output.
Pin 11: TXD Serial asynchronous communication output or Serial synchronous communication clock output.
Pin 12: INT0 Interrupt 0 input.
Pin 13: INT1 Interrupt 1 input.
Pin 14: T0 Counter 0 clock input.
Pin 15: T1 Counter 1 clock input.
Pin 16: WR Write to external (additional) RAM.
Pin 17: RD Read from external RAM.
Pin 18, 19: X2, X1 Internal oscillator input and output. A quartz crystal which specifies operating frequency is usually connected to these pins. Instead of it, miniature ceramics resonators can also be used for frequency stability. Later versions of microcontrollers operate at a frequency of 0 Hz up to over 50 Hz.
Pin 20: GND Ground.
Pin 21-28: Port 2 If there is no intention to use external memory then these port pins are configured as general inputs/outputs. In case external memory is used, the higher address byte, i.e. addresses A8-A15 will appear on this port. Even though memory with capacity of 64Kb is not used, which means that not all eight port bits are used for its addressing, the rest of them are not available as inputs/outputs.
Pin 29: PSEN If external ROM is used for storing program then a logic zero (0) appears on it every time the microcontroller reads a byte from memory.
Pin 30: ALE Prior to reading from external memory, the microcontroller puts the lower address byte (A0-A7) on P0 and activates the ALE output. After receiving signal from the ALE pin, the external register (usually 74HCT373 or 74HCT375 add-on chip) memorizes the state of P0 and uses it as a memory chip address. Immediately after that, the ALU pin is returned its previous logic state and P0 is now used as a Data Bus. As seen, port data multiplexing is performed by means of only one additional (and cheap) integrated circuit. In other words, this port is used for both data and address transmission.
Pin 31: EA By applying logic zero to this pin, P2 and P3 are used for data and address transmission with no regard to whether there is internal memory or not. It means that even there is a program written to the microcontroller, it will not be executed. Instead, the program written to external ROM will be executed. By applying logic one to the EA pin, the microcontroller will use both memories, first internal then external (if exists).
Pin 32-39: Port 0 Similar to P2, if external memory is not used, these pins can be used as general inputs/outputs. Otherwise, P0 is configured as address output (A0-A7) when the ALE pin is driven high (1) or as data output (Data Bus) when the ALE pin is driven low (0).
Parents should be understanding and have a friendly relationship with their kids. Pressurizing never helps afterall.
I remember throughout my school days I used to be equally worried about my scores or grades…& the better I used to get sometimes though my paren’t expectations kept on rising….
One thing I learnt is that it’s the journey which matters not just that that last moment when you reached the top. And Reaching the Top is easier but staying there for long is difficult and there are always others waiting to pull you down from there.
“The female brain has shrunk by about the same proportion.”
McAuliffe reported the comments made by John Hawks, anthropologist from the University of Wisconsin , who argues that the fact the size of the human brain is decreasing doesn’t necessarily mean our intelligence is in decline as well.
Some paleontologists agree with this diagnosis that our brains may have become smaller in size, but increasingly efficient.
1. Avoid becoming overweight. Obesity raises the risk of breast cancer after menopause, the time of life when breast cancer most often occurs. Avoid gaining weight over time, and try to maintain a body-mass index under 25 (calculators can be found online).
2. Eat healthy to avoid tipping the scale. Embrace a diet high in vegetables and fruit and low in sugared drinks, refined carbohydrates and fatty foods. Eat lean protein such as fish or chicken breast and eat red meat in moderation, if at all. Eat whole grains. Choose vegetable oils over animal fats.
3. Keep physically active. Research suggests that increased physical activity, even when begun later in life, reduces overall breast-cancer risk by about 10 percent to 30 percent. All it takes is moderate exercise like a 30-minute walk five days a week to get this protective effect.
4. Drink little or no alcohol. Alcohol use is associated with an increased risk of breast cancer. Women should limit intake to no more than one drink per day, regardless of the type of alcohol.
5. Avoid hormone replacement therapy. Menopausal hormone therapy increases risk for breast cancer. If you must take hormones to manage menopausal symptoms, avoid those that contain progesterone and limit their use to less than three years. “Bioidentical hormones” and hormonal creams and gels are no safer than prescription hormones and should also be avoided.
6. Consider taking an estrogen-blocking drug. Women with a family history of breast cancer or who are over age 60 should talk to their doctor about the pros and cons of estrogen-blocking drugs such as tamoxifen and raloxifene.
7. Don’t smoke. Research suggests that long-term smoking is associated with increased risk of breast cancer in some women. Need help quitting? Consider participating in WebQuit, the Hutchinson Center’s online smoking-cessation study.
8. Breast-feed your babies for as long as possible. Women who breast-feed their babies for at least a year in total have a reduced risk of developing breast cancer later.
9. Participate in a research study. The Hutchinson Center is home to several studies that are looking at ways to reduce the risk for breast cancer. Check our website periodically for studies that might be appropriate for you. Just go here and click on “How You Can Help.”
10. Get fit and support breast cancer research at the same time. Regular physical activity is associated with a reduced risk of breast cancer. Ascend some of the world’s most breathtaking peaks while raising vital funds for and awareness of breast cancer research by participating in the Hutchinson Center’s annual Climb to Fight Breast Cancer.
Pomegranate to protect breast cancer
The pomegranate is a fruit of fine and very versatile in the kitchen that has proven a precious ally against breast cancer. In practice, the pomegranate significantly reduces the incidence of breast cancer based on hormonal research that led to these results was published in the journal Cancer Prevention Research of scientific piece of information. The pomegranate is scrumptious by itself, but also used to build desserts or major courses like the prominent risotto with pomegranate.
Breast Cancer Prevention trough Healthy Food Habits
Statistics showing that women in the US have higher risks of developing breast cancer than women in China or Japan and that breast cancer risks for Asian women that migrate in the US increases over generations, becoming similar to that of US white women, thus suggesting that lifestyle or environmental factors rather than genetics being responsible for this differences, led to a study in order to identify these factors.
Breast cancer is the most common malignancy in women and the second leading cause of cancer death (exceeded by lung cancer in 1985). Breast cancer is three times more common than all gynecologic malignancies put together. The incidence of breast cancer has been increasing steadily from an incidence of 1:20 in 1960 to 1:7 women today.
The National Breast Cancer Foundation estimates that each year over 200,000 new cases of breast cancer will be diagnosed and over 40,000 patients will die from the disease. Breast cancer is truly an epidemic among women and we don’t know why.
“Mammograms are among the best early detection methods, yet 13 million U.S. women 40 years of age or older have never had a mammogram.”
