CULTURAL QA 03-2022-29 BEING A COMPILATIONTHERE MAY BE ERRORS
Q1 How does the pancreas know when torelease insulin or glucagon? What sends the signal for it to do that? A1 Ken Saladin Former professor ofhistology (microscopic anatomy)Updated 15h It doesn’t get the signals from an external source. Theinsulin-secreting beta cells take up glucose from the blood and metabolize it.One of the enzymes in this pathway is called glucokinase. It controls an earlyrate-limiting step in glucose catabolism (breakdown) and appears to be thecell’s glucose sensor. Through its metabolic products, it signals mitochondriato initiate events that trigger insulin release from the cell.[1][2] When bloodglucose level falls, glucokinase activity falls, there’s less signaling of themitochondria, and therefore less insulin release. The glucagon-secreting alpha cells are less wellunderstood. They’re much fewer in number than the betacells in experimental animals (rats, mice), therefore harder to obtain, andthere are more technical difficulties in studying them. At low levels of bloodglucose, sodium- and potassium-driven electrical changes occur in the plasmamembrane of alpha cells. Those electrical changes trigger a calcium releaseand—as in so many other cells from neurons to human eggs—calcium triggersexocytosis, in this case releasing glucagon by. Glucagon stimulates the liverto release glucose into the blood. As glucose level rises, it inhibits the calcium signalingmechanism in the alpha cells. The exact mechanism of glucose-driveninhibition was still not well known as of my source, but that was quite a whileago (2009).[3] The gist of allthis, for most purposes, is that alpha and beta cells don’t rely onsignals from any external source. Their release of glucagon or insulin, respectively, isregulated by their own rate of glucose uptake, via signaling pathways insidethose cells that endocrine cell physiologists are still painstakingly workingout. Science marches on. Q2 Why is it better to use the chip in acredit or debit card rather than swiping it? A2 Steven Haddock Lives in Toronto, ON(1959–present) 23h The chip isessentially hardware in your card that can’t be changed. All your financial information that makes the chip work is hard wired into it. Thechip can’t be removed without destroying the card. You can’tduplicate a chip in another card for this reason, so even if a fraudster managed to getall the information out of it it can’t be used in another card. It’s entirelysecure. The swipe stripis just a piece of magnetic tape. It’s a piece of cake to copy that informationto another piece of magnetic tape on anothercard. Q3 What are the side effects of fluoridebeing added to the public water system? A3 Steven Haddock Studied at YorkUniversity (Canada) Mar 16 Children get farfewer cavities.That means dentists make less money and starve to death, leavingthe entire community without dentists.Fluoride can also cause minor pitting onteeth. That’s it. There’sfar less fluoride in drinking water than in toothpaste. Q4 Why did, in ancient times, civilizationdevelop around Mediterranean? What were people who were living in other places(modern France, Germany, Russia, etc.) doing? A4 Matt Riggsby MA Archaeology, BostonUniversity Mar 7 The Mediterranean had a few things going for it. Theseinclude: Nice climate. The Mediterranean is a very pleasantplace to live, with comfortable temperatures and rainfall adequate foragriculture, so it’s relatively friendly to the growth of populations andurbanism. Easy transportation. Moving stuff by river isconsistently something like a fifth of the cost of moving stuff over land, andmoving stuff by sea is consistently something like a fifth of the cost ofmoving stuff by river. The Mediterranean is a relatively gentle sea with a lotof coastline and rivers penetrating deeply inland, making regional integrationrelatively easy. The neighbors. This is one of the big ones, I think.One of the world’s earliest civilizations arose in Mesopotamia, just on theother side of the Levant from the Med. One of the others popped up along theNile valley, itself a major feeder into the Med. Egypt and Mesopotamia providedkey ideas for the development of civilization which were adopted in the MiddleEast and into Europe. What people weredoing elsewhere was living largely Neolithic lifestyles with a smattering ofimported technologies. People in non-Mediterranean Europe and more northerlyparts of western Asia lived in relatively small farming villages or, in some ofwestern Asia, as nomadic horse-riding tribes. Eventually they adopted urban living as well, but thoseideas hadn’t yet penetrated and been adapted for use by local cultures. Q5 We (Bachelors) are planning to buy a commonwashing machine for two houses. If we install in one house the electricity willbe drawn from that house only. So the electricity bill will high for thathouse. How to split among us? A5 Venkateswara Swamy Swarna , formerScientist, Metallurgist, Quality / NDT Manager at Department of Atomic Energy,India (1967-2008)Answered Fri You can install a sub-meter and draw the power for thewashing machine from that only. That way, you will knowthe units consumed in each bill and divide that amongst both the houses Q6 Electric wire is generally round incross section. What difference in conduction would it make if it were square ortriangular? A6 Angus Mccamant BS in ElectricalEngineering & Physics, Colorado State University (Graduated 1982)Mar 16 This is actuallynot a simple question. Thefirst answer appears to be just the difference between a rectangular ortriangular cross section and a circular cross section. The conductance is proportional to the cross sectional area. There are morefactors involved in the shape of wire. One big one is cost. Some of the otherare how compact you can wind a bunch of turns of the wire and how the wires areused. Another factor is the voltage on the wire. The last factor is thefrequency. At lowfrequencies and moderate voltage (less than 1KV) where you want tominimize the resistance and you have limited area you use squareor rectangular wire. This is done in many transformers and high currentcommercial motors. At highfrequencies and high voltages you always use round wires as this results inmore uniform electricfields and less chance of breakdown as well as lower loss at the MHzfrequencies. Q7 Why are human beings not suitable forgenetic experiments? A7 Claire Jordan Degree in biology andfolklore; programmer, shop owner, secretary on newspaper 20h Ethical considerations, as Rachel says, but also we havea small number of offspring who grow very slowly. The NHS hasrecently agreed to fund genetic editing treatments for two childhood geneticdisorders, one of which costs nearly a million pounds per patient, and theother nearly two million (although they’ll get a discount by buying in bulk). The NHS thinks this is worth it, notjust on humanitarian grounds but also financially, because we *think* these treatmentswill be a one-off complete cure, so these children will not go on toneed years or decades of expensive support. But it will be fifteen years beforewe can be absolutely certain these children are cured, and not just inremission - whereas with a rat you can be sure in about four months. My note- I assume these can be diseases like autism andtype 1 diabetics. Q8 How much does drain cleaning cost? A8 Cleaning Services Melbourne AnsweredJan 12, 2021 For common orsimple blockages, like a blocked toilet or kitchen drain, the cost can rangefrom $ 80 to $ 200. For something more serious, like a short run of blockeddrain pipes, the average fee would be $ 200 to $ 500. 2ND ANSWER- Rajkumari Maderna , works atStudents Answered Apr 15, 2016 It depends on thenature of work and time it consumes. Kitchen drains and shower drains cleaningis cheaper while sewer drain cleaning will costly. It will be better if youdiscuss and settle a price for the work so there will not be a price increaseonce work start. 3RD ANSWER- Gopala Krishnan, former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966-2004) Answered justnow Recently there wasblockage in septic tank line in my home in Chennai, India. Septic tank clearingusing suction method to lorry tank was above 1500–00, but by opening andremoving two inspection points to removeblocks I was charged Rs 2000–00. But the persons coming with lorry andequipment for septic tank cleaning are experts to analyse and open the approximate blockagepoints. They come prepared with all blockage clearing equipment Q9 Does washing clothes in cold water killgerms? A9 Steven Haddock, lives in Toronto, ON(1959-present)Answered 55m ago Yes. Its a littleless efficient at doing it than using hot water, but using cold water and laundry detergent is still fatalto the little buggers. Adding a little chlorine or oxygen bleachwill also help kill them. 2nd answer Effie May Answered 58m ago No, most of the time washing clothes in cold waterdoes not kill germs. There are some washers that have sanitizing cycles andthat works. A10 What's special about the VishnumayaTemple? Vignesh Pn Fri Devotees getimmediate Solutions for their problems.
