CULTURALQA 07-2023-21 Q1 How can salt be removed from sea waterchemically?
A1 Rebecca Williams, MS in Accounting andFinance, New York University Jul 7 Salt can be removedfrom seawater chemically by a process called reverse osmosis. Reverse osmosis is a processthat uses pressure to force water molecules through a semi-permeable membrane.The membrane allows water molecules to pass through, but it blocks salt molecules. 1.The process of reverse osmosis begins withseawater being pumped into a high-pressure chamber. The pressure forces thewater molecules through the semi-permeable membrane, leaving the salt moleculesbehind. The water thatpasses through the membrane is called permeate, and the salt that is leftbehind is called retentate. The permeateis then collected and can be used for drinking water or other purposes.The retentate is either discarded or recycled back into the seawater. Reverse osmosis is a very effective way to remove salt from seawater.It is also a very energy-intensive process. Here are some other chemicalmethods that can be used to remove salt from seawater: Electrodialysis is a process that uses an electric currentto separate ions in water. The ions that are responsible forthe salinity of seawater, such as sodium and chloride, can be removed byelectrodialysis. Membranedistillation is a process that uses a semi-permeable membrane to separate waterfrom salt. The membrane allows water molecules to pass through, but it blockssalt molecules. The waterthat passes through the membrane is then boiled, and the steam is condensed toproduce pure water. Ion exchange is a process that uses a resin toremove ions from water. The resin is loaded with ions that are opposite incharge to the ions that are in the seawater. The ions in the seawater are thenexchanged with the ions in the resin. The choice of which chemical method to use depends on anumber of factors, including the cost of the process, the energy requirements,and the quality of the water that is required. My note-The Arabian countries get drinking water by any of the process. Especially insoudi Arabia where there are no rivers. Q2 Humor: What are some of the greatestexamples of presence of mind? A2 Sandeep Maheshwari, Updated 2y Teacher addresses astudent and asks: “How many kidneys do we have?" “Four!", The student responds. “Four? Haha,” The teacher was one of those whotook pleasure in picking on his students' mistakes and demoralizing them. “Bring a bundle of grass,because we have an ass in the room," the teacher orders a front bencher. “And for me a coffee!”, thestudent added. The teacher wasfurious and expelled the student from the room. The studentwas, by the way, the humorist Aparicio Torelly Aporelly (1895-1971), betterknown as the "Baron de Itararé". On his way out ofthe classroom, the student still had the audacity to correct the furiousteacher: "You asked mehow many kidneys ‘we have’. We have four: two of mine and two of yours. ‘Wehave’ is an expression used for the plural. Enjoy the grass.” Life demands muchmore understanding than knowledge. Sometimes people, because they have a littlemore knowledge or ‘believe’ that they have it, feel they have the right tounderestimate others. Q3 Do you know this about India? A3 Kaushal,Updated Jun 14 Don't be surprisedto see the picture. It is true that once upon a time you couldgo from Delhi to London by bus because then the world's longest road route usedto be from Calcutta to London and buses also used to ply on this route. This service was started by Sydney's Albert Tour andTravels Company, not by any Indian or British. Started in the early 1950s, itran for about 25 years, but later it had to be discontinued due to variousreasons. The fare ranged from just £85 to £145. Starting fromCalcutta, via Banaras, Allahabad, Agra, Delhi via Lahore, Rawalpindi, Kabul,Kandahar, Tehran, Istanbul to Bulgaria, Yugoslavia, Vienna to West Germany andBelgium, this bus used to reach London. During this, itused to run about 20300 KM and cross 11 countries. This bus used totake almost 70 days to reach. Q4 How do I quickly lower blood sugar?

Those who drink alcohol more are at a higher risk of developingvarious types of cancer. My note- Why the government totally enforceprohibition of alcohols, including army services? At one time I recollect in my boyhood, buseswere stopped, checked for alcohols andthen permitted in Kerala. Even one with smell of alcohol was not permitted totravel Obesity: Being overweightincreases the risk of chronic diseases and various cancers, including thecolon, rectum, breast, pancreas, kidneys, and liver.

A5 Yuvraj Kumar, Intrested in Animals andtheir characteristics.7h Male Hyenas, Handsdown. These guys have got it bad. First of all, female Hyenas have apseudo-penis from which they give birth (By rupturing it), and yes, it hurts.The mortality rate of Hyena Cubs is 60%, not because they are huntedmercilessly by Lions and other opportunistic predators, which they actuallyare, but because theysuffocate on their way out of that narrow organ. Even aftersurviving through this, Male hyena cubs are discriminated against. Until theyreach adulthood, i.e. at the age of 2–3 years, they are kept in the Cackle.They are treated as inferior to females cubs, and face bullying, mutilation andgets their food stolen by them. After reachingadulthood they leave the Cackle and try to join another Cackle. Now, thehierarchical structure of Hyena society is Matriarchal, that means it's lead bya female Hyena. Thefemales are bigger than male, so they dominate them brutally. They have to climbthe ranks by hunting for the cackle, or if one of the prominent male membersdies. And sadly, the most prominent male Hyena of the cackle is still beneaththe newly-born female cubs. Male Hyenas rarely lives a long life,they are bullied, mutilated and remain hungry for long. Their life is prettysad and depressing. There life is sodepressing that theyhave a laughing sound to signal distress, it's not some evil Hyena laughas you see it. It's simply a signal for distress.
