CULTURAL QA 08-2023-11 Q1 Whatis important in a water purifier before buying them?
A1 Gopala Krishnan, Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004)Just now Nowadays we getclosed type R O System more and withadded features. These added features like adding minerals, passing UV, stagesof filtering are looked in to. Most companies now provide a large paper filter unitexternally through which the inlet of water is given. Warranty for power supply unit, free A M C period arelooked in to. Irrespectiveof the type of R O S purchased, make sure the inlet water is as best aspossible by cleaning over head tank regularly. This makes the pH value by about 150 and output pH below50. In my R O systeminstalled at home, normally the output water to the storing tank has a pH valuearound 20 only. Q2 Howmuch money does turning off the central air save compared to using a windowunit and a ceiling fan together? A2 Gopala Krishnan, Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004)Just now In India window AC is almost phased out.In large buildings like telephone exchanges centralized AC systems areprovided. Normally two systemsare provided, alternately switched. If at all one system fail, otherwill be switched ON. I have seen inmany banking institutions, the engine alternator is provided, which will takethe load of all AC Units also. These alternators can be ofdifferent types. If at all AC systems fail, fans are switched ON forlimited time till AC system is brought back. AC isimportant with modern computerized operations anywhere. UPS battery is provided of sufficient capacity whereinverter AC is provided. My note- Homesequipped with central AC are very few. But there are. Q3 Whathappens if the prostate is removed? A3 HealthyMen, Men’s Health specialistJul 26 If the prostate issurgically removed, a procedure called a prostatectomy, it can have severaleffects on the body. Here are some key points: 1. Infertility: The removal of the prostate gland leads to the absence ofseminal fluid during ejaculation, resulting in dry orgasms.This means that natural fertility is no longer possible. However, prior to surgery, some menmay choose to bank their sperm (cryopreservation) for future use in assistedreproductive techniques, such as in vitro fertilization (IVF), if they desire to father children. 2. Sexual Function: The nerves andblood vessels that are essential for erectile function are in close proximityto the prostate. During a prostatectomy, especially ifit’s a radical prostatectomy (removal of the entire prostate), these nerves maybe unavoidably affected.However, surgeons canattempt nerve-sparing techniques to preserve erectile function. Despitenerve-sparing efforts, many men still experience a temporary or permanentdecline in erectile function after surgery. It can take several months orlonger for erectile function to return, if at all, and some men may requiretreatments like medications, penile injections, or devices to achieveerections. 3. Urinary Changes: After prostateremoval, the urethra might undergo some changes due to the surgery. Theprostate surrounds the urethra like a donut, and its removal may result inchanges to the urethral structure or scarring. This can lead to temporary or permanent urinaryincontinence, which means the ability to control urine flow might becompromised. Post-surgery, some men may experience urinary leakagewhen they cough, sneeze, or engage in physical activities,known as stress incontinence. Others may face a frequent and sudden urge tourinate, known as urge incontinence. 4. PSA Levels: Prostate-specificantigen (PSA) is a protein produced by both normal and cancerous prostatecells. After prostateremoval, PSA levels in the blood should drop significantly, as there is noprostate tissue left to produce PSA. Elevated PSAlevels after a prostatectomy can indicate the presence of residual prostatetissue or recurrence of prostate cancer. Regular PSA tests are importantfor monitoring any potential recurrence. It’s important to note that while prostatectomy can be aneffective treatment for prostate cancer, it’s not without potential sideeffects. Each individual’s response to the surgery canvary, and it’s essential for patients to have a thorough discussion with theirhealthcare team to understand the potential risks, benefits, and long-termimplications of the procedure based on their specific medical history andcancer stage. My note- I read long back in “kids health” the topic on removal ofenlarged prostrate is done as last resort when other methodsfail. An expert surgeon has to do the operation since near byglands of urethra is not touched even accidentally. Q4 Onthe kitchen platform in the SE corner, if there is a sink and gas stove side byside, can there be a strained relationship in the family? A4 Gopala Krishnan,Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004)Just now Kitchen locationbased on Vasthu principle is south East/ North East in southern India. WhileKerala it is mostly North East, in Tamilnadu it is South East. In flats these principlescannot be looked in to. It is abasic scientific requirement the stove position and sink must be away as far as possible.If they are near, while cleaning or water tap switched ON,sprinkles of water can fall on burner and ignited flame may go OFF. Other way, ifwater fallen on burner and the stove is ignited, burner many not burn.Cleaning water is with chemicals added and may make stains in the stove. Stove is hot andsink is cool. In certain areas, it is a belief, they should not be very close.Strained relations in the family because the stove and sink near, is a thinking with somefamilies. We follow many suchbeliefs. An example- number13 is not considered good in many countries. They may number 12 Ainstead of 13. Q5 Whatis the hole on the back of passenger airplanes? A5 Jagrata Banerjee, Studied Aviation UpdatedJun 25 Thanks for givingme the opportunity to answer the question… You may be probablytalking about The hole at the tail end of the aircraft?? Yeah, this is the exhaust port of theHidden Powerhouse of the aircraft. This is alsoknown as the Auxiliary Power Unit (APU). Auxiliary power unit is a small turbine engine located atthe tail of the aircraft. It too uses the usual Aviation Fuel from theaircraft's fuel tanks. The APU is started, when the engines are not running orthe plane is not connected with an external power source. The APU is switched off after the enginesare started, as it is no longer needed. Sometimes, theAPU is kept on for air-conditioning purposes during take off, as engines’ bleedair is not used for AC during take off (specially at hot and high operations). The APU is again started after the plane exits the runwayafter landing. This is because, immediately upon reaching thegate the external power source may or may not be available and using theengines for running the A/C and electrical system is not at all economical andis totally impractical. Therefore, the APU is kept on in such cases. On a smalljetliner, such as an Airbus A320 or a Boeing 737, the APU uses fuel at the rateof 160–200 kg/h. On the other hand, a big Jumbo Jet, such as a Boeing 747 or anAirbus A380, uses fuel at 400–500 kg/h. Functions of APU— Supply highpressure bleed air to air conditioning packs while on the ground. Provides electrical power to the aircraft, while the mainengines are switched off. Provide hydraulic and pneumatic power to start the mainengines of the aircraft. Can be used tostart engines while the aircraft is in flight. All the above QA are from Quora website on 11-08- 2023. Quora answers need not be 100% correct answers . Compiled and posted by R.
