CULTURAL QA 04-2023-24 Q1 Canyou feel the difference after an oil change? Does changing engine oil make adifference?
A1 ErikaFernandez, Car Lover Apr 7 Yes, changing engine oil can make a difference in theperformance of your vehicle. Regular oil changes areimportant to keep your engine healthy and running smoothly, as oil plays acrucial role in reducing friction between moving parts in the engine,preventing metal-to-metal contact that generates heat and causes wear and tear. Neglecting to change your oil regularly can lead to avariety of problems, from lower fuel efficiency to costly engine damage. After an oil change, you may feel a difference in theperformance of your vehicle, such as smoother acceleration, better fuelefficiency, and reduced engine noise. Fresh oil helpsimprove the engine's efficiency, and changing your oil regularly can extend thelife of your vehicle. The length of time you can go between oil changes withsynthetic oil depends on various factors, includingthe type of synthetic oil, the manufacturer's recommendations, and your drivinghabits. In general, synthetic oil can go 10,000 to 15,000 miles, orsix to 12 months, between changes under "normal" driving conditions.However, it is important to follow the manufacturer's recommendations and toconsider your driving habits when determining the oil change interval. Q2 Howdoes the Internet work? A2 Digital Services And Products, BusinessConsultant | Digital Marketing Services | IT Guru Apr 10 The Internet is aworldwide network of computers that communicate with each other using a set ofstandard protocols. It allows users to communicate with each other, accessinformation, and perform various tasks using devices such as computers,smartphones, and tablets. In this article, we will look at how the Internetworks and the different components that make it possible. The Internet is essentially a network of networks, witheach network consisting of various devices such as routers, switches, servers,and computers. Thesedevices are connected to each other using physical links such as cables,fiber-optic lines, and wireless connections. The physical links thatconnect the devices are referred to as the network infrastructure. The Internet uses a set of standard protocols toensure that different devices can communicate with each other in a standardizedway. The most importantof these protocols is the Transmission Control Protocol/Internet Protocol(TCP/IP) protocol suite. This protocol suite is responsible forensuring that data is transmitted reliably between devices on the Internet. When a user wants to access a website, they enter thewebsite's URL into their web browser. The browser then sends a request to thewebsite's server, requesting the web page. The server then sends the web pageback to the user's browser, which displays the page on the user's screen. To facilitate this communication, the user's device and thewebsite's server exchange packets of data. A packetis a unit of data that is transmitted over a network. Each packet contains aheader and a payload. The header contains information about the packet, such asthe source and destination addresses, while the payload contains the actualdata being transmitted. The Internet uses the Domain Name System (DNS) to translatehuman-readable domain names (such as Google) into IP addresses (such as172.217.6.110). This allows users to accesswebsites using easy-to-remember domain names instead of IP addresses. To ensurethat data is transmitted reliably between devices, the TCP protocol breaks datainto smaller packets and sends them individually. Eachpacket is acknowledged by the receiving device, and if a packet is lost ordamaged, the sender retransmits it. This ensures that data is transmittedreliably, even over unreliable networks such as the Internet. Anotherimportant protocol used by the Internet is the HyperText Transfer Protocol(HTTP). This protocol is used to transfer web pagesfrom the server to the user's browser. HTTPS is a more secure version ofHTTP that uses encryption to protect data transmitted between the user's deviceand the website's server. In conclusion, theInternet is a complex network of networks that allows devices to communicatewith each other using a set of standard protocols. The TCP/IP protocol suite isresponsible for ensuring that data is transmitted reliably between devices,while the DNS translates domain names into IP addresses. The Internet hasrevolutionized the way we communicate and access information, and itsimportance in modern society cannot be overstated. My note- Most ofus would have received information frombanks etc,recently to ensure they visita site of bank with HTTPS and not HTTP Q3 Whatare some mind-blowing facts about food?

A4 Bhuvana Rameshwar, Lives in India(1989–present)Mon Dal chaawal.. Lentils and Rice, paruppu saadam, pappu -annam and so on in other Indian languages.. We Indians love it.why? Because it issimple to make.. No Because it is eatenin all Indian houses.. No Because it is easyon our budget.. No Because it is richin proteins (dals).. No Because it is oftenmade by mothers who are lazy.. No Because it is thequickest to make.. No Because it isour comfort food. A simple mashed dhal with littlesalt, rice and if possible a little butter or ghee is given as the first solidfood for a baby. Allbabies associate the dhal rice with their mother, grandmother, their first home.Toddlers, primary school children also prefer this to other spicy Indiangravies and rasam. We have memories ofour first “solid food “ carried on through childhood to adulthood. Our tastebuds have sweet memories of this new tasty meal given after drinking milk ormilk based paste like cereals for many months. Dal chaawal was such a change in taste from milk.This nostalgia makes us love dhal-rice. After falling sick too we are given dal- chaawal, a non spicy, yet tasty food for speedy recover. The most satisfyingmeal in all Indian houses. Potato fry is the best side dish for adults. Even on feast ,festivals marriage, reception and otherhappy days we in southern India, especially TN serve a liitle mashed dhal tohave with rice and ghee as a, starter, on our big platter on the banana leaf. Notice the dhal(cooked yellow gram) on rice, a little ghee makes it heavenly. Everybody begins, with dhal - rice.What gives more satisfaction in a feast more than dhal - rice? Every host knowsthat is the way to connect emotionally with his guests. All other hi end itemsare only add ons. The dhal rice has already satisfied the guests. My note- Many use green dhal and rice.Especially in srardha thoordhal is not used. Q5 Whatfacts about Japan do foreigners not believe until they come to Japan? A5 Visar Krasniqi, Trusted for greatsleep & coffee, expert in snooze & brew Apr 3 One fact is that Japan is one of the safest countries inthe world, and it is not uncommon to see children walkingto school alone or women walking alone at night without fear of being attacked.The low crime rate and the strong emphasis on social order and respect forothers are deeply ingrained in Japanese culture.

Service isan important part of Japanese culture, and the concept of"omotenashi" (hospitality) is deeply ingrained in Japanese society. Everywhere you go in Japan, from hotels and restaurants to shops andtourist attractions, you can expect to be treated with the utmost respect andcare. Q6 Whydoes engine oil become dark brown or even black over time? A6 Erika Fernandez, Works at Freelancer,Novelist, Writer Wed Engine oil becomes dark brown or even black over timedue to a variety of factors. During normal operation, heat cycles naturally darkenmotor oil. When the engine reaches normal operating temperature, the motor oilheats up, and then it cools while the car sits in the parking lot. Some additives in motor oil are more susceptible todarkening in the presence of heat than others. Inaddition, normal oxidation can darken oil. Over time, the oil's viscosity changes, and it becomescontaminated with dust and dirt, which causes it to turn muddy and look verydark or blackish in appearance. Thick, very dark,or black engine oil usually indicates that the oil has been exposed to dirt ordust contaminants that lead to a soot. The color of the oil does not dictate the efficiency ofoil, and judging an oil’s efficiency on color alone is not possible. When regular engineoil changes are neglected, normally free-flowing lubricating oil breaks down,becomes contaminated, ceases to flow, and is transformed into a thick soup ofwaste.

A8 TinyNair, Cardiologist at PRS Hospital, Trivandrum Jan 15 ‘By the way, don’t open the ceramic box (jar)’ announced the husbandbefore he left home. Feminine curiosity was no lessintense in 700 BC as it is today. Ms. Pandora opened the box, and as per Greek mythology, letall the human misery escape – from debility to ageing, from disease topandemic, everything. She panicked and closed the lid quickly. She didn’trealize that the cures like youthfulness, hope, health and happiness was lyingat the bottom of the box. But your wife knows. In 1961, American scientist Leonard Hayflick fromPhiladelphia made an astounding discovery. In the lab, cultured humancells could divide to a maximum of 50 times, and then it perished. Chromosomes, the coiled structure inside our cells thathouses our genetic code, has a protective ‘shoe’ called telomere at its end, toprevent the edges from fraying, during cell division. In 1980, Elizabeth Blackburn from Australia proved that asingle-cell organism ‘tetrahymena’ can be kept immortalin the lab petri-dish by constant supply of an enzyme ‘telomerase’ that keepsthe sole of the telomere ‘shoe’ intact. Biologic immortality atcellular level was now in sight. The discovery fetched her the Nobel Prize in2009. Token 32 came riding on a stainless steel wheel-chair,a frail, elderly lady, her ‘salt-pepper’ unkempt hair, ‘crow-feet’ side trims;an unmatched blouse with a wrinkled silk-saree causally wrapped over her torso.Her heavyweight goldchain, gymnastic-ring earrings and jumbo-size gold bangles indicated that shewas in no financial insolvency. ‘How are you, Amma?’ I try to greet her with asmile, the best that Icould sport at 2-30 in the afternoon. ‘I am unwell son, aches and painall over, unable to move, all effect of old age’ the patient announced. It was only when I looked at her medical records, it struckme; she is my age. My same age! Either her‘telomere’ is bad, or my ‘hair dye’ is good. Self-grooming ismuch more than skin-cream and hair-dye. Watch a rodent, a lab animal, a cat or a dog. It spendssubstantial amount of time in self grooming. Licking,shaking, rubbing scratching, every way it can, it tries to keep itself clean.It is vital for its survival by preventing infections and parasites. A labanimal that stops self-grooming, signals that it is sick and it is going todie. Self-groomingin humans have evolved a lot from bathing and brushing to fairness creams andhair colour. Self-grooming improve self-esteem, but thereis more. It improves self-perception, not just what others think about you, butwhat you think about yourself. A film star, concerned about how people perceive her (showcasedself-image) is not what we are talking about. It is what you think aboutyourself (mirror self-image). A distorted mirror self-image is a problem. The verydefinition of ageing has changed, not everyone above age 65 years is old. Those between 65and 75 years is termed ‘young old’, 75 years till 85 ‘middle old’ and 85 pluslabelled ‘older old’. In countries like Japan, there are many ‘older old’ whoare healthy and fit, proving that ageing does not necessarily make youunhealthy. Bright and active people like biologistRichard Dawkins (82) thinker Daniel Kahneman (88), and linguist Noam Chomsky(91) proves the point. This ledresearchers to come up with the concept of ‘frailty’. Frailty is combination ofdifficulty in moving around (mobility), slow thinking or poor memory (cognition),loss of muscle and bone mass and difficulty in activities of daily living.Elaborate scores are in place to quantify frailty. While only 10% of those between 65 to 75 years arefrail, the frailty percentage increase to 25% above 85 years of age. The US NationalHealth and Aging Trend Study of 4800 patients done at Johns Hopkins Universityat Baltimore in 2021 showed that those who had low self-esteem andself-perception scores at the start of study, had a 41% higher risk ofdeveloping frailty on seven year follow-up. So take careof your image to yourself. As acclaimedtrainer Tom Hopkins puts it ‘You are your greatest asset. Put yourtime, effort and money in grooming yourself.’ Not for others to appreciate, but for yourhealth. The jar your wife digs her finger into now and then, whichyou presume to be face cream, is in reality the pandoras box; she is trying toscoop out the left-over ‘youthfulness’. (From my articlepublished in the HINDU today) My note- What abeautiful writing- Such skill is God given. Perhaps one member in the group may not agree to my note. For himthese are silly ones. Q9 CanI buy only the outside unit of a split AC? A9 Gopala Krishnan, Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004)Just now The outdoor unit isthe prime part of the split AC. The cost of indoor unit is only 10% of the total price. As far as myknowledge goes Newoutdoor unit alone cannot be obtained from shops in India. But ACservice shops may be able to give 2nd hand or repaired unit sometimes. No wise person will try to purchase AC outdoor unitalone.Most will dispose both the units to repair shops for the price they could getand purchase a latest AC unitwith in the budget. Q10 Whatare some mind blowing facts that most people don't know? A10 Krishna Kamat, Sun Here are some mindblowing facts about Nebula that most people don't know A Nebula is a giant cloud of dust and gas in space.Some nebulae (more thanone nebula) come from the gas and dust thrown out by the explosion of a dyingstar. Other nebulae are regions where new stars are beginning to form. The Nebula was made largely of hydrogen with some heliumand small amounts of the remaining naturally occurring chemical elements. Nebula come in manydifferent shapes and sizes. There are four main types of nebula — Planetary nebula, Reflectionnebula, Emission nebula, and Absorption nebula. The closestknown nebula to Earth is called the Helix Nebula. It is the remnant of a dying star. It is approximately 700light-years away from Earth. The word nebulacomes from the Latin word for cloud.
