Q1 Does Wolff’s law work in reverse? Doesnot putting stress to bones cause the bone to relapse to its original state? A1 Ken Saladin Textbook author andprofessor emeritus May 5 Wolff’s law works both ways.It says that bone remodels itself in response to use or disuse. If a bone issubjected to increasing stress, osteoblasts deposit more bone, increasing itsdensity and sometimes its outer dimensions in response. If a bone is subjectedto reduced stress, osteoclasts dissolve more bone and its density decreases. Neither one is a “reverse”operation of the law—it’s just a matter of continual remodelling in response tochanging need. Q2 Why is Europe investing heavily intrains? A2 Tomaž Vargazon Practicing atheistApr 20 All means of travelhave their niches. Forshort trips you may take a car or a bus, but for longer trips you needsomething more comfortable. Trains fulfil a useful niche for trips too long to take abus and too short to take a plane. Planes are dirtyand noisy but, crucially, have their own limitations that is not directlylinked to travel: mandatory security checks prolong every plane trip by an houror more, getting your luggage can add another hour and you can expect to lose athird hour going to and from the airport. While planes are significantly faster than trains, theentire trip, from your home to your destination, can be faster on a trainsimply because moving to and from the train is quicker and you arrive somewherecloser than is the case with the planes. In truth, aircraftonly begin to edge out planes for trips longer than about 500 km. This is how500 km looks like in Europe: This is how far atrain could be the superior mode of travel from Vienna, Austria Of course geographycomes into play as well. Rome is on the edge of the circle from Austria, butthe Alps prevent an efficient route for now (two tunnels are under constructionto recertify this), so a plane could be preffered. Not so much for Berlin orWarshaw though. Europe is densly populated enough for trains to makesense, so Europe is investing in trains. What a bunch of oddballs we are. Q3 Why does Bengaluru look richer thanChennai? A3 Deepa Shankar Lives in Bengaluru,Karnataka, India Apr 15 Because the city ofBangalore IS richer than Chennai is. IT has taken the Bangalore’s GDP on agalloping run. With IT, you have a huge influx of migrants. And these migrantsdemand high rise buildings, malls and fancy cars. Ergo, Bangalore has a lot ofthese. To severalpeople, these look ‘rich’. Local Tamils andKannadigas from both the cities are exactly the same. Wherever they are! Theyare content with vadai/vade, idli, dose/dosai, veshti/panche, Indian music,film weekends, mango pickles and cotton sarees. I clicked this picture (below)today while passing one of my favourite landmarks in Chennai. Nalli has swankier buildings todaybut we still end up going to this old building. The snobbish Mylapore womanwill not cross the Mount Road and set foot in this part of town, btw. This is the crowd Iidentify with in either city: I love taking a bus to Seshadripuram, shopping inSivananda Stores and coming back in an auto/Uber. In Chennai, I canspend aeons in Mylapore maada veedhi, shop in Co-Optex, spend evenings in thebeach and come back in a bus or share auto. It it sounds mundane to you, youbelong to the high rise glitz and glamour parts of Bangalore. If my idea of funappeals to you, you belong to all of Chennai or the old parts of Bengaluru.Don’t judge me, I like my Scotch neat while wearing a Cooptex classic. Thehusband man is all about microbreweries and obviously likes that in Bangalore. However hard I try( may be I don’t try hard enough), I look like the quintessential middle classwhether I am buying spinach from the streets or sitting in business classairplane seats. I am the personification of Chennai. I see the same in London,the city I currently live in. People detest anything new. They refuse to razedown old houses, still have fireplaces and wait for it, 4 bedroom houses withONE bathroom. Sounds very familiar to the Chennai-ite? Bangalore has had toextend and make way for its huge influx of people and their demands. The Chennai tenant will notpay a 50k rent for a 3BHK in some remote corner of the city. TheBengaluru tenant will do that. Below is a pic of the community I stayed inuntil I was in Bangalore. This is my Chennaihome: You can see thecontrast, right? Mosaic in a home that’s supposedly ‘well to do’ is found onlyin some places… old Bangalore and Chennai are part of this ‘elite’ list. Q4 I have read and seen wildly conflictingversions from no pain ever to pain at almost every stage. At what point does afetus actually feel pain while being aborted? Does chemical abortion causepain? A4 Claire Jordan Degree in biology andfolklore; programmer, shop owner, secretary on newspaper11h Certainly not much before 20 weeks, and some sources saynot before 26 weeks. Much earlier than 20 weeks and thenervous system is just not plumbed in enough. I’ve been thinkingabout an analogy for this. The zygote, the very early embryo, is definitely nota person - it’s a *recipe* for making a person. It gradually gets moreperson-ish as it grows. Byabout 26 weeks, if not before, it’s *somebody*, it’s conscious and can haveexperiences. You can extend therecipe metaphor and think of it like baking a cake. When you make the cake youpour all your ingredients in and mix them, but at that point it’s not a cake,just a bowl of ingredients. If you take it out of the oven after five minutesit’s still a bowl of ingredients. But there comes a point when it’s still inthe oven but you can say it’s a cake, even if it’s not finished yet and it’s anunderdone cake. Q5 In India 1kg peanuts cost us around80/- and it takes 3 kgs of peanuts to extract 1 liter of ground oil but theysell at 100/- how do they get profit? A5 Siva Kumar Bachoti Former SoftwareQuality Assurance Manager Sun Shelled peanutsi.e. seeds, sell at a retail price of Rs. 129/- per kg as on today. Oil grade peanutwholesale price : around 80/- per kg. You can assume, any oil extracting company gets it muchcheaper, let it be 50/- per kg (farm price). The oil yield isaround 44%.That mean, the net cost after extraction is 112 /- per kg. If youadd overheads, may be it comes to 120 bucks per kg oil. Groundnut cake,leftover from oil extraction. Sold at around 50/- per kg. (used as fertilizerand animal feed). Marked retail price: 235/- a liter Note, it is 910grams ONLY, works out to 259/- per Kg. I wonder who isselling you at 100 bucks. May be you can buy it wholesale, retail it and makehell lot of money. Q6 Why do South Indians regard only thesouthernmost four states as part of South India? A6 Srikanth V Studied at Wharton ExecutiveEducation (Graduated 2010) Sun It is the NorthIndians who consider the four states as South Indian states whereas people ofthese four states consider the four states as any other state of India and donot distinguish between north and south. Since the four states speak fourdifferent languages ( each of the languages centuries old and culturally rich)and most of the people up north do not even know. One of my colleagues from UP,a well educated person, said all four states of South are insignificant as faras Indians (he calls people up north as Indians and people down south as SouthIndians) are concerned. It will surprise us when we see the name plates inrestaurants in North write the delicacies as Chinese, Thai, Indian, SouthIndian, etc. I was never irritated but only pitied their ignorance. Over the last 3 decades, peoplehave come to realise the significance of Southern States. When I went to Northin 80s, the literate as well as the illiterate people used to taunt on ouraccented Hindi. I used to immediately switch over to English becausewe had options of our mother tongue and the global language but they werealways restricted by their wrong notion that Hindi is our national language andI always told them that Hindi is also one of our national languages. So, to sumit up, it is the northeners who defined which are to be called as South Indianstates as they have the right to define it appears Q7 What are the requirements regarding theelectricity department when we are installing an air conditioner for the firsttime? A7 Gopala Krishnan , former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966-2004) Answered justnow The electric supplysingle phase or three phase is provided depend on the WIRED LOAD. So mostbuilders discuss with house owner AC requirements and provide socket provisionfor AC units. If it is single phase and proposed to install AC units. EB willprovide 3 phase supply for the wired load. If cutout provided in the post, therequired type of fuse wire and wires from line are provided. If power cable isprovided to home, required gauge of fuse wires are provided. in the cutoutsafter meter. If it is in flats, wiring may not be there for more AC points,wiring has to be done, suitable circuit breakers has to be provided for theadded load. In big flats , a lot of transformers would have installed alreadyto cater to the heavy loads win in the premises. Q8 If your hands come into contact withliquid mercury, how long do you have to wash them to remove it completely? A8 Mathew P. Vanderburg Updated Sun Mercury is practically insoluble in water, and soaps anddetergents do little to help. Mercury cleaning is done withpowders, which have a large surface area and encourage mercury to stick tothem. If you are in alaboratory or other industry that works with mercury, you should be aware ofstandard procedures for dealing with splashes. If for some reasonyou have enough mercury to get a splash at home, you can wipe it down with arag and then use some flouror icing sugar to clean your hands, rub this powder all over the skin that hascome into contact with the metal . Then you can rinse off the powderand wash with soap. People of mygeneration played with mercury at school. Now I know this is dangerous, but itwas 60 years ago and I'm still here. As I mentioned, Iknow now that it was somewhat irresponsible, but it was before the currentparanoia about the pollutants and toxins that surround us.
