Indian scientists have found a new method to improve the transportation of fluids such as chocolates, lotions, and sauces by tuning their viscosity and elasticity during materials processing in the food and personal care products industry, an official statement said on Monday.
Usually the transport of fluids through pipelines involves displacement of a more viscous fluid by a less viscous one. This creates instabilities at the interface between the fluids, which leads to complex patterns of intrusion of the former into the latter, and results in impurities during the transportation. Hence instabilities need to be removed to ensure smooth transportation of fluids during processing, a Science and Technology Ministry release said.

Scientists from Raman Research Institute, an autonomous institute of the Department of Science & Technology have found that by changing the viscosity of the displacing fluid and the concentration-dependent elasticity of the displaced fluid, the instability can be reduced and the roughness of the interfacial pattern and the efficiency of displacement can be controlled, it said.
In this study, funded jointly by DST, SERB India and Raman Research Institute, the researchers used corn starch aqueous suspensions (a non-Newtonian visco-elastic fluid), and glycerol-water mixtures (a Newtonian fluid) in their experiment. In the first set of experiments, the viscosity ratio between the two fluids (glycerol-water mixtures, the displacing fluid, and corn starch suspension, the displaced fluid) was changed by changing the viscosity of the glycerol water mixture. The viscosity of corn starch suspension was constant in this case while the viscosity of the mixture of glycerol and water was varied by changing the proportion of glycerol in the glycerol-water mixture.

In the second set of experiments, where the effect of elasticity of corn starch suspension is investigated, the viscosity ratio was kept constant. The elasticity of corn starch suspension was changed, thereby changing its concentration, while viscosity ratio between the fluids was kept constant by choosing different concentration of the glycerol-water mixture. The research has been published in the journal 'Colloids and Surfaces'. The suppression of instabilities leads to an efficient displacement of the more viscous/visco-elastic fluid, which is useful in transportation of materials in industries such as food processing, oil recovery and sugar refining, the statement said.
"The study can also help understand instabilities at the interface between two fluids which is essential in the design and enhancement of processes, like filtration and electro-deposition of metals, as also mixing and de-mixing of two phases like that of sugar and chocolate which can affect the texture and taste of the chocolate," it added.(IANS/ MBI)

Malgudi, a small fictional town in South India has been part of the childhood of most Indians. It is an old, shabby, and peaceful town that is unruffled by politics. The stories set in this small town ring the sense of belongingness in the hearts of its readers. The familiar feeling that feels like home resonates with their soul. And teaches important life lessons to the readers through simple tales. Malgudi Days is one of the books that every Indian child should read. The book is a compilation of 32 short stories that paint a beautiful picture of small-town in India around the '60s and '70s
R. K. Narayan, one of the most well-known and popular writers within India and outside India is the creator of this town and the occurrences of this town. The stories follow the characters Swami and his friends through their everyday lives. Be it the story of fake astrologers who scam and loot the people by his cleverness, or the story of a blind beggar and his dog where the money blinded the man with greed; each story has a lesson to learn, morals and values hidden in it. As the stories are simple, easy to understand yet heart-touching it makes it easy for the kids to connect with each character and imagine the story as if the reader themselves were the protagonist of the story. In simple words, we can say that R.K. Narayan simply told stories of ordinary people trying to live their simple lives in a changing world.

As written during the Indian Independence movements and finally published in 1943. The stories in the Malgudi days beautifully encapsulated the transitioning milieu of the British era to post-Independence India. Each of the stories portrays a facet of life in Malgudi and simultaneously a life in an Indian town. R.K. Narayan was one of the first writers who pioneered Indian writings in the English language and the book was later republished outside India in 1982 by Penguin Classics. Thus, the book enjoyed a worldwide audience. The New York Times even described the virtue of the book as "everyone in the book seems to have a capacity for responding to the quality of his particular hour. It's an art we need to study and revive."
The beautiful storytelling of the book was assisted by beautiful illustrations allowing the children to let their imagination teleport them to the world of Malgudi. All the illustrations in the book were illustrated by the world-renowned cartoonist, R.K. Laxman who is also R.K. Narayan's younger brother. The illustrations complimented the scenes from the stories and excited the children, keeping them engaged in reading the book for hours.

The short stories from Malgudi Days were later adapted into a television adaptation in 1986. This show was directed by actor and director Shankar Nag. It was filmed both in Hindi and English, containing 54 episodes and the first 13 episodes respectively. Later the series was revived for additional 15 episodes. The show featured several popular celebrities from the Kannada film industry of those days – Girish Karnad, Vishnuvardhan, Ananth Nag, Arundhati Nag and Vaishali Kasaravalli, to name a few. The series was premiered on the Doordarshan channel and became the window into the town Malgudi for many. The show did not only excel in its storyline the TV adaptation elevated the storytelling as the show was technically very sound and stood out in its fantastic detailing in terms of locations and sets. With the cinematography being creative The Malgudi days- TV series once again warmed the hearts of both young ones and adults.

Malgudi- our childhood home
Malgudi days hold a special place in the hearts of whoever has read the book as a child. With the detailed descriptions of the town and stories one almost gets a feeling that they've visited the place themselves. The characters, Swami and his friends feel like they were all readers' childhood friends. The surreal feeling of being home in the world of Malgudi. The world of Malgudi is intimate, warm, lifelike, and engaging. The setting is modern, and the life portrayed in these stories is contemporary. Still, there is an old-time air about It. R K Narayan once described Malgudi as "Malgudi is where we all belong, and where we wish we lived."

Well, if you'll notice then the moon takes twenty-nine days to complete its lunar cycle, whereas women's menstrual cycle is generally 28 days! Coincidence? I think, not.
It is believed that when a woman goes through her menstrual cycle, she goes through the different lunar energies. In fact, in ancient times it was said that the natural rhythm of women was to menstruate under a new moon and ovulate under a full moon.
At the same time, it is also believed that the cycle and its stages are connected to different seasons, namely, spring, summer, autumn, and winter.
Let us see how the lunar cycle is related to a woman's menstrual cycle!
It must be noted that the menstruation period is during the new moon period and also during the winter season. It is said that this is a reflective phase; a phase of silence, introspection, and solitude. During this phase, a woman's body is more sensitive, and so they're able to connect with it and hear the messages it gives. Interestingly, this is also the time when a woman naturally recycles energy as she menstruates, and hence, it's also the for their rest and recovery.
The Crescent moon represents the pre-ovulation period. This is also the season of spring, and so the time corresponds to an increase in physical energy. During this period, a woman's mental strength is at its peak and their thoughts are much clearer. At the same time, emotions are more stable during this period, and because of which women tend to be more social and outgoing.
This phase of the moon represents ovulation, and the season associated with this phase is summer. It must be noted that this period is full of energy and vitality. At the same time, this period plays a significant role in the lives of women because it's actually a fertile phase in all aspects of their life, be it personal or professional. During this period, the self-confidence and self-esteem in women tend to rise, and along with this, an increase in their sex drive can be seen very well.
This phase of the moon represents pre-menstruation, which is also associated with the autumn season. During this period, a woman's physical energy starts to decline. Metaphorically, just like a tree sheds its leaves, a woman, too, feels the need to let go of anything that is not benefiting her. At the same time, memory and the ability to concentrate decrease in this period.
I hope, now you will not think of the moon just as a celestial body, but as a companion in the lives of women!

The Pakistan Electronic Media Regulatory Authority (PEMRA) has directed Pak TV channels to stop airing what it calls indecency and intimacy in dramas, Samaa TV reported.
A notification issued by the authority states that it has been receiving numerous complaints from viewers who believe that the content being depicted in dramas does not represent the "true picture of Pakistani society".
"PEMRA finally got something right: Intimacy and affection between married couples isn't 'true depiction of Pakistani society and must not be 'glamourized'. Our 'culture' is control, abuse, and violence, which we must jealously guard against the imposition of such alien values," said Reema Omer, Legal Advisor, South Asia, International Commission of Jurists.
"Hugs, caress scenes, extramarital affairs, vulgar and bold dressing, bed scenes and intimacy of married couples are being glamourized in utter disregard to Islamic teachings and culture of Pakistani society," PEMRA stated, as per the report.
The authority added that it has directed channels time and again to review content with "indecent dressing, controversial and objectionable plots, bed scenes and unnecessary detailing of events".
Most complaints received by the PEMRA Call Centre during September concern drama serial "Juda Huay Kuch is Tarah", which created quite a storm on social media for showing an unwitting married couple as foster siblings in a teaser for an upcoming episode. However, it only turned out to be a family scheme after the full episode aired, but by that time criticism had mounted on HUM TV for using the themes of incest to drive the plot, the report said.
