A1 Gopala Krishnan,Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004)7mo I am writing thisanswer from Chennai, India. Some sort of sink was used in middle class familiesfor decades. When I was about ten years R C C slab was provided in kitchen andoven using wooden logs was fitted on it. My mother desired some sort of sink for keeping usedvessels and a raised square portion was made with bricks on the slab.It was the first sink known to me. Vessels used were kept in it for next daycleaning, taking it outside the kitchen. Many homes in later period provided tap and waste line fromit. Regular sink wasnot available in many homes even in 1980’s. Sinks in ceramic were available from 1990’s in my officialquarters. Now in my new home stainless steel sinks are provided. Onein kitchen and another in work area. The benefit is used vessels can be kept and keep kitchen somewhat neat. At leisure time they can be cleaned. At nightit can be cleaned. If vessels are transferred to work area, kitchen can be keptclean, delicate vessels if necessary kept in kitchen sink. >From the outlet letinto public system/ soak pit, if not periodically cleaned >and refreshers usedcan give foul smell. Small creatures can get in to sink. Now stainless steelnet cup is available to fit in to sink outlet replacing old cover. Thisprevents all small creatures getting in . However periodicalcleaning of outlet with cleaning items and application of room freshner is amust. Pouring diluted phynoil in the night in sinks will remove anysmell than any other cleaning items. Q2 How hard is it to relocate a kitchensink? A2 Gopala Krishnan, Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004) Just now I am answering fromChennai. In these areas R C C slab is laid for kitchen and work area tables. For sink the R C C is sized insuch a manner that proposed sink will fit in that area. Over itgranite is laid and for sink area, granite is cutaccordingly after placing the sink. For relocating, the sink can be removed without muchdifficulty. But in the new area, granite and RCC has to becut with proper saw and fitted. But areawhere sink is removed is a weak area. If R C C slab ismade and fitted over it perfectly and new granite is added, still externally it may lookperfect, it is a weak point. With R C C andgranite cutting saws become common with contractors, job is not difficult. Howeverexpenses will be more. Q3 What is the most abundant preciousmetal? A3 Erika Fernandez, Knows aboutChemistry17h A preciousmetal is a rare, naturally occurring metallic chemical element that has a higheconomic value. Precious metals are usually less reactive thanmost elements, and they have a high lustre and ductility. Precious metals are often usedas currency, investment, or industrial raw materials. There are many precious metals in the world, such asgold, silver, platinum, palladium, rhodium, iridium, osmium, ruthenium, andmore.However, not all of them are equally abundant or accessible. The abundance of a precious metaldepends on its occurrence in the Earth’s crust, its extraction from oresor minerals, and its supply and demand in the market. Silver has an average concentration of 0.075 ppm in theEarth’s crust, which means that one ton of crust contains about 0.075 grams ofsilver. Silver ismostly produced as a by-product of copper, lead, zinc, or gold mining. Silver has alower demand and a lower price than gold, but it also has more industrial uses. So based on thesenumbers, it seems that silver is the most abundant preciousmetal in the Earth’s crust.However, these numbers may vary depending on the source and method ofmeasurement. Also, the abundance of precious metal in the crust does notnecessarily reflect its availability or accessibility in the market. The supplyand demand of precious metals may also affect their price and value. Q4 Is it bad to use all the water in atank? A4 Aliya,Teacher at Noble Grammar School(2014–present)1h Using all the water in a tank is not necessarily bad, butit depends on the context and purpose of the tank. If the tank is meant for storing water foressential needs such as drinking, cooking, or hygiene, then using up all thewater could lead to inconvenience or even potential health risks if there is noimmediate access to a water source. However, if thetank is used for non-essential purposes such as irrigation, swimming, orindustrial processes, then using up all the water may not have significantconsequences, as long as there is a plan for refilling orreplenishing the tank. In general, it isimportant to consider the purpose of the tank, the availability of watersources, and the potential impact of using up all the water before doing so. My note- Normally in water tanks outlet pipe is fittedabout 3 inches above the bottom. This enables sedimentssettle in bottom is not let out throughthe outlet pipe. However while fully emptying some sediments may come finally. It is advised not to take out water fully from tank. Q5 How does a stethoscope enhance adoctor's ability to diagnose medical conditions? A5 Tiny Nair, Cardiologist at PRSHospital, Trivandrum May 30 As a kid I used tobe fascinated by the doctor-uncle’s stethoscope when my mom would go for acheck-up. My mom wouldsit on the side-stool, he would place the stethoscope over her back for 5seconds and write a prescription; to me it looked like pure magic. 2 decadeslater, as I became a doctor myself, I could understand the futility of such anexercise, the doctor would have heard nothing worthwhile to make a diagnosis. Human ear can hear from 20 – 20,000 Hz. Heart sounds standstart at around 20 Hz. By 50 years age,the lower hearing limit moves up to 50 hz. So, to tunein to the heart sounds, you need to auscultate with full concentration andspend sufficient time to make sense of it. Still useful Because he was inbed 3, it looked rude to go from 2 to 4, and so I said hello to him. He was a young man, came in withchest pain. ECGs, Echo normal. Blood tests includingtroponin ruled out heart attack and a negative D-dimer excluded pulmonaryembolism. He waswaiting to go home on a prescription of pain-killers and antacids. As I auscultatedwith my stethoscope, I could hear a distinct rubbing sound, the pericardialrub, something that indicates inflammation of pericardium, the covering of theheart. It ispericarditis, I announce. He stays back, and diagnosis of ‘viral pericarditis’ isconfirmed. (early pericarditis, all investigations may benormal).

Imaging in, Stethoscope out Advances in thescience of imaging especially echocardiography has taken the thrill out ofdiagnosis. Introduction of Bedside and handheld echo made the heart image lightup at the touch of a button at the bedside. With a clarity and sensitivity far more than a human ear. Wait But even today, the stethoscope has one unchallenged use.It is one ID that would letsmoothly sail past all the hospital security. Notwithstanding,fingerprint and face-ID.
