Compare/Difference between Controlled Rectifier and Uncontrolled Rectifier

 Controlled Rectifier: 

i) When SCR are used to convert AC to DC they have controlled output voltage, so it is called a controlled rectifier output.

ii) Diodes conducting immediately after its voltage has become positive.

Uncontrolled Rectifier:

i) In this rectifier, the circuit using diodes only are called uncontrolled rectifier circuit.

ii) Unlike diodes, SCR does not become conducting immediately after its voltage become positive. Because it requires triggering gate pulse for forward conduction of SCR.

What types of waves are shown on computer?

In our universe there are unlimited waves are exist, but in this waves we only see few of them.

We are capable of see visible light only in electromagnetic spectrum.

The list of visible lights are:

1)  Violet

2)  Indigo

3)  Blue

4)  Green

5)  Yellow

6)  Orange

7)  Red

These are the Visible light which we can see easily.

But your question about which waves are shown on computer ? is that your question right, Than its right answer is, On computer there are basically three colours are used or waves are used to display any pictures or videos is Red, Green and Blue colours or waves.

 

Beacuse of these three basic colour combination we able to see many different colours on our computer screen.

Transverse wave examples

They move up and down about their equilibrium positions. Some examples of transverse waves are:

• The ripples on the surface of the water
• The secondary waves of an earthquake
• Electromagnetic waves
• The waves on a string
• Stadium or human wave
• The ocean waves

Kya Matkke ka paani fridge ke paani se jyaada phaayademand hota hai ?

Garmiyo ke season aate hi hamaare mann mein kuch thanda ho jaya aise sab khayaal aate hai. aisa sochana ye toh hamaare liye bilkul natural hai. Actually garmiyo ke season mein hum jyaada kar ke thande-thande padarth khaana pasand karte hai. Jaise ki ice-cream, kulfi, cold drinks, fruit juice aur sabhi prakar ke beverages. Lekin kya aap ko pataa hai, yeh sabhi padarth ko thanda karne ke liye usse fridge mein rakhaa jaata hai.

Garmiyo ka season chaalu hua nahi ki hum fridge ke thande-thande paani peene lagte hai. Thanda paani peene ke baad hamaara pyaas bujha toh jaata hai. Lekin kya aapko pataa hai fridge ka paani hamaare sehath ke liye bilkul achha nahi hota hai. 

1) Kya aap ko pataa hai fridge ka thanda paani peene se hamaaraa shareer bahut aalsi jaisa mehsus karta hai.

2) Hamaara digestive system bahut hi weak hota jaata hai.

3) Fridge ka thanda paani peene se hamaaraa shareer uss thande paani ko garam karne mein bahut jyaada urjaa kharch kartaa hai, aur kya aapko pataa hai wo urjaa aati kahaa se hai, wo urjaa hamaare blood se aati hai. Iss ka matlab yeh hua ki jo blood baaki sab organs ko supply mein kaam aati thi wo blood aap ke thande paani ko garm karne mein lag gaya. Aur maanlo aisa hi chalta rahaa toh ek din aisa aayega ki aapke jitne bhi organs hai wo sab dheere-dheere jawab dete jaayenge, iss ka matlab ki wo kharab hote jaayenge, kyun ki aap ka blood ka supply ab uss organs ko nahi mil rahaa hai jiss organs ko blood ki supply ki jarurat thi.

3) Thande paani peene se aap ko constipitation ki bimaari toh aani hi hai ye paakaa hai. Iss constipation ko hindi mein hum kabj ke naam se jaante hai.

4) Aur yahaa tak aap jaan lijiye jo log jyaada fridge ka paani peete hain unn logo ko latrin jaldi nahi utarta hai. Issliye wo log bathroom mein ghanto-ghanto news paper lekar baithe rahatein hai.

Isse ye saaph ho jaata hai ki agar hum fridge ka paani peete hai, toh ye maanlo ki hum marne ke kagaar par hai.

Agar aap ko thanda paani peena hi hai toh aap matkke ka paani pee sakte hai. Ye bahut hada tak safe hota hai. Darasal matkke ka paani naturally normal temperature hota hai, jisse hamaaraa shrareer usse aasaani se digest kar letaa hai. Aur waise bhi aap sab jaante hai ki matkka ek eco-friendly natural cooling substance hai, jo paani ko normal taarike se thanda karta hai.

Agar hum baata dein ki Fridge jo hota hai yeh eco-friendly nahi hota hai. Agar aapke ghar mein fridge hai toh jaan lijiye ki wo eco-friendly nahi hai. Kyun ki fridge constantly ek baut khatarnak gas release kartaa hai aur wo hai Chloro-Flouro-Carbon (CFC). Chloro-Flouro-Carbon (CFC) Hamaare environment ke liye bahut hi dangerous hota hai, ye gas global warming ko barakarar rahne mein madat kartaa hai. Aapko hum bataa dein ki global warming usse kehte hai ki jab hamaare environment ka temperature dheere-dheere badhane lagataa hai, hamaare normal temperature se.

Agar hum matkke ka paani peeyenge toh hamaara sehath ke saath-saath hamaara environment bhi fresh and polluted free rahega.

Kya aap sab jaantein hain ek aisa jeev hai hamaare iss dharti pe ki agar usske shareer ke hum jitne bhi tukade karenge toh har ek tukada ek naya shareer banayega

Hamaari iss duniya mein ajibo-garib alag-alg kism ke jeev-jantu paaye jaante hai, lekin bahut se jiv-jantu ke baare mein hum jaante honge lekin bahut se jeev-jantu aise bhi hai jinke baare mein hum kuch nahi jaante. Hamaare hi iss planet earth pe paaya jaanewala ek aisa jeev hai jo ki bahut hi adbhut jeev hai. Iss ki ek hi specialty sabhi jeevo se alag kar deti hai aur wo hai regeneration jee haa regeneration hi ek maatr aisi isski adbhut speciality hai jisse yeh hamaare liye aur baaki sabhi jeev-jantuwo se bilkul khass banaati hai. Toh chaliye jaante hai aisa wo kaun sa jeev hai. Toh chaliye hum aap ko uss jeev ka naam bataate hai, uss jeev ka naam hai planaria.

Aap sab ne isske baare mein sunaa aur padha jarur hoga apne student life mein, Actually iss planaria topic ke baare mein aap ne science ke kitaab mein jarur padha hoga. Yeh planaria ka size lag bhag 0.1 inch se lekar 0.6 inch tak hota hai agar hum baat kare isski height ki tab ye 30 cm se bhi jyaada height badhate hai. Chaliye dekh lijiye ki ye dikhata kaisa hai.

Yahaa par aap sab dekha saktein hai iss planaria ko, jiske baare mein hum baat kar rahe the. dikhane mein yeh hamein bahut chhota dikhayi pada raha hai, lekin iss ke kaarnamo ke baare jab aap jaanoge toh aapke hosh udd jaayenge. Toh chaliye jaante hai iss ke kaarnamo mein ke baare mein.

jaise humne pehele line mein bataya tha, ki jab iss planaria ke hum kitne bhi tukade-tukade kardenge toh har ek tukada ek naya planaria ko janm degaa aur issi prakriyaa ko hum english mein regeneration of planaria kehte hai. Iss regeneration of planaria ki prakriya kaise dikhati hai yeh aap iss image ko dekh kar achhe se samajh jaayenge.

Jaise ki aap sab ye dekh rahein hai ki ek planaria ko jab 3 tukado mein hum jab kaate hain toh har ek tukadaa ek puraa planaria ban jaata hai. planaria ka kataa hua head ka part ek pura planaria banaa chuka hai, waise hi usska trunk, tail ka kataa hua part ek pura planaria ka shareer banaa diya hai. Ye koi jaruri nahi hai ki hum usska sirf head, trunk or tail jaise part kaatenge tohi wo pura planaria ka body banaane mein capable hoga, aisa bilkul bhi nahi hai. Hum chahein toh kahi se bhi usske shareer ka part kaatenge toh wo pura planaria ka body banaane mein capable hoga. 

Aap sab jaise jaante honge ki jab lizard (Chipkali) ka tail wala part cut ho jaata hai toh wo phir se nikal aataa hai. Lekin lizard (Chipkali) ke saath regeneration wala prakriya usske tail wale part ke saath hi hotaa hai, baaki body ke saath nahi hotaa hai. Lekin jab hum baat kar rahein hai iss planaria jaise jeev ki toh isska pura shareer mein regeneration prakriya hone ki capability hoti hai, hum iss planaria ka body kisi bhi angle se kaate aur kahin se bhi kaate toh ye har ek part ko ek pura planaria banaane mein capable hoga.

Aap sab ye jaanne ko bahut utsuk honge ki planaria jeev kahaa rahata hai ? Toh jaan lijiye ye plaaria fresh or salt water dono mein ye paaya jaata hai, jaise ki ponds, river,spring, streams etc. chaliye jaantein hai ki kya ye planaria jaise jeev hum insaano ke liye khatarnak hoga, toh aap jaan lijiye bilkul nahi. Hai na yeh sabhi jeev-jantuwo se adbhut.

Hamein haftein mein ek baar toh baahar ghumane jarur jaanaa chahiye

Bhaag dauda ki iss zindagi mein hum bahut busy rehtein hai. Roj apne-apne kaam ko sambhalne mein lage hua hai, kya kare yeh sab toh hamein sambhaalna hi hoga nahi toh hamaari zindagi kaise chalegi. Hum kabhi-kabhi iss zindagi se bahut hi pareshaan ho jaate hai, yeh sab hamaari roj ke thakaan aur din-bhar ki tension ke wajase hota hai. Kya hum kuch kar nahi sakte iss thakaan aur din-bhar ke tension ko kam karne ke liye. Toh chaliye hum jaante hai ki iss thakaan aur tension ko kaise kam kiya jaaye.

Hamein haftein mein ek baar apne-aap ke liye jarur kuch time dena chahiye. Kuch time dena ka matlab yeh hai ki hamein haftein mein ek baar kisi ek adventurous jagahh par jarur jaana chahiye. Jab hum aisi kisi adventurous jagahh par jaayenge toh hamein bahut achha mehsus hoga. Hamein aisa lagega ki chalo aaj kuch nayaa aur kuch alag sikhane aur dekhane ko milega. Mera kehne ka matlab yeh ki hamein uss jagahh par jaanaa chaahiye jahaa pahaad ho, jahaa nadiyaa ho, jahaa paani ke jharne ho, jahaa khuli jagahh ho, kuch aisa jagahh jahaa par aas-pass koi ghar na ho.

Jab aise jagahho par hum ghumne ke liye jaayenge toh hum apne-aap ko bahut hi halka mehsus karenge. Hamein aisaa lagega ki humaare sar par se bahut hi badaa bojha utar gayaa hai. Uss jagahh ki khuli hawaaye jab hum apne andar lenge toh hamaare shareer ka oxygen level badhega, aur hum apne-aap ko bahut aaraam feel karenge. Aisa jagahh aapko bahut hi jyaadaa gaon ke side mein hi dekhane ko milega. 

Chaliye mein apne baare mein bataataa hun, mein mumbai mein lagbhag 5 saal ho gaye hai, lekin mai aapko sab kya bataau ab tak gaon nahi gayaa. Mujhe bahut mann hota ki iss saal gaon chalaa jaau lekin kya karu padhaai ke wajase gaon nahi ja paata hun. Aap sab soch rahe honge ki aise kaise nahi gaon jaa saktaa hun. Actually mein jab 9th standard pass hua tab meine apne ssc board ke liye tayeyaari shuru kar diya, iss wajase mai uss saal gaon nahi jaa sakaa. Aur jab mai ssc pass hua tab fyjc ka online form bharna padaa phir iss ke liye tayeyaari shuru kar diya, jaise hi fyjc pass hua toh meraa 12th ka tension sar pe aa gayaa. Phir kya 12 pass hone ke baad 3 saal abhi polytechnic course kar rahaa hun aur soch lijiye ab tak mai gaon nahi gayaa.

Yehi experience aap sab se share karnaa chahataa tha, ki aap bhi meri tarahh apne khush bhari zindagi ko yu hi jaane na dein iss din-bhar ki zindagi mein se zara sa time nikaal kar kahi adventurous jagahho par jaakar aayein. Isse aapko junun aur kaam kar ka motivation level boost ho jaayega. Aap sabhi ko mai yehi kehna chahunga, ki aap sab mere jaise galti naa kare kyun mujhe koi idea nahi tha ki adventurous jagahh ghumne se kitna achha mehsus hota hai.

Hamein apne kaam ke saath-saath apne swaasth ka bhi khayal rakhanaa chahiye. Kyun maine bahut laapar waahi ki hai, aur baad mein mujhe pachataanaa pada rahaa hai. Aaj ke iss modern city mein agar hum apne-aapka swaasth ka khayaal nahi rakhenge toh barut hamein problem ko face karna pada sakta hai. Aap sab toh jaise jaante hi honge iss samy mein aaj kal kitne naye-naye bimaariyaa aarahein hai. Iss liye aapne aapko sambhaal kar rakhiye, baaki kaam baad mein sabse pehle apne-aap ke liye samay nikalne se aap ko kabhi-bhi tension, thakaan jaise problem kabhi nahi aayega. Take care youself because your helath is wealth.

Kya aap jaantein hai iss corona lockdown mein hamaare waataawaran ko kitna phaayada hua hai ?

 Iss corona maahamaari ne sabki jaan aafat mein daal di hai. Jidhar bhi dekho traahi-maa traahi-maa ho rahaa hai. Koi bhi log sukun ki zindaki kya hoti hai yehi bhul gaye hai. Aaj jise bhi dekho wo sabhi pareshaan nazar aa rahein hai. Thodi derr ki liye agar raaste par nikalo toh ambulance ki gaadiyon ka aawaaj hi sunne ko miltaa hai. Shudh hawaa kya hotaa hai yeh hum sab bhul hi gayein hai kyun ki sabke cheharo par mask lage huye rehtein hai. Ab na jaane ki yeh corona virus ka janjaal kab khatam hoga. Abhi dekhaa jaaye toh kuch isske baare mein kahaa nahi jaa sakta hai. kyunki ye corona virus itnaa dheere-dheere khatarnak hote jaa rahaa hai ki din-par-din kuch kahaa nahi jaa sakta hai.

Aap sab ko yeh jaise ki maalum hoga ki iss corona lockdown ke wajase hum sab abhi ghar par hi rehtein hai. Din bhar ghar pe rehte-rehte bor hote jaa rahein hai. Agar koi manoranjan ke liye kitna bhi upaay banaale, magar unn sabhi cheejo se wo ubb jaatein hai. Lekin kya kare ab iss corona mahaamaari ke wajase ghar par rehnaa hi pada taa hai, yeh hum sab ki majburi hai. Ab toh roj ke jaise subahh uthkar bazaar jaao aur bazaar se sabjiyaa lekar ghar par aao yehi roj ka kaam ho gaya hai. ghar par hi khao, piyo aur so jao yehi din-bhar ka kaam bana gaya hai.

Aaj sabh ko jaise maalum hoga ki iss corona virus ke lock-down mein kitno ka ghar ujada gaya hai. Kitne hi pati-pani ka divorce ha chuka hai. Ghar baithe bahut se log apne mein maara-maari kar rahein hai. Iss lock-down mein yehi toh sunne aur dekhane ko roj mil rahaa hai. Darasal yeh sab aisaa kyun ho rahaa hai kya aapne kabhi socha hai, toh chaliye hum aapko bataa dein ki ye kyun ho rahaa hai. Ye issliye kyun ki sabhi log ghar par hi baithe-baithe ubb gaye hai toh iss liye bahut se chid-chide se honne ke wajase wo chhote-chhote baato ka bahut jaldi buraa maan letein hai. Aur iss wajase pati-patni aapas mein lad rahein hai. Yesa iss liye ho rahaa hai, kyun ki ghar baithenne ke wajase sabhi logo ka maansik stithi par bahut buraa asar padaa hai.

Ghar mein baithe-baithe pareshaan ho kar zara sa samaya ke liye road par niklo toh puraa road sunaa-sunna sa lagne lagtaa hai. Bahut se log lock-down ka naam sunte hi apne-apne gaaon ka ticket book karne lagte hai. Aur apne-apne gaaon ke liye chal padatein hai. Aap sabhi ko hum yeh bataadein ki pichale lown-down jiss time corona virus first time aaya atha uss time mein sampurn lock-down ka government ne announce kiya tha tab aapko pataa hai sabhi bus,train aur hawaai-jahaaj band hoye the, tab gaaon paidal aur apni-apni gaadiyon se jaate waqt kitne hi log mar gaye the. wo sab aap ne news mein zarur sunaa hoga. wo drishya sach-muchh bahut hi katarnak drishya tha.

Corona lock-down mein bahut se burre din hum sab ko dekne ko milein, magar iss lockdown ke wajase bahut hi jyaada acche parinaam bhi dekhane ko milein hai. chaliye hum aap sab ko bataatein hai. Corona lockdown ke wajase traffic roado par nahi lagtein the, aur iss liye hamaare waatawaran mein waayu pradushan jise english mein hum Air pollution ke naam se jaantein hai. Waayu pradushan ka level hamaare waatawaran mein bahut jyaada maatra mein kam hua hai, aur ye hum sab ke liye bahut hi khushi ki baat hai. Kyun ki hum sab ko jaise ki pataa hi hoga saharo mein Air quality kitne down hoti jaa rahi thi lekin iss lock-down ke kaaran sabhi ghar mein rehte the, roado par gaadiyaa nahi chalti thi, saare industries factories mein taale lag gaye the.

Chaliye jaza isski gehraii mein chal ke jaantein hai. Aap sab ne news mein akhabaaro mein ye jarur padha ya sunna ho ki bangkok mein school aur colleges band kar diye gaye hai, ye sab air pollution ke wajase hi hua tha. Lekin iss corona lock-down ke wajase bangkok desh mein waayu pradusan bahut maatra mein kam hui hai sirf-or-sirf road traffic kam hone se. Waayu pradushan jyaada honne ke wajase Taj mahal ek dhaba-dhabba jaise dikhane laga tha, lekin iss waayu pradushan ke kam ho jaane se Taj mahal phir se chamak ne laga hai. 

Lock-down ke wajase India ke Yamuna aur Ganga jaise nadiya ek dam saaph-suthar ho gaye hai. Kyun ki iss lock-down ke wajase sabhi dhaarmik sthaal band ho gaye the, toh sabhi log apne-apne ghar mein hi puja-paatha karte the, aur yehi kaaran hai ki na koi yamuan nahaane gaya aur na koi ganga nahaane gayaa. Logo ke mandir na jaane ke wajase mandir mein jyaada maatra mein phul maalaayein bhi nahi hotein the. Aap sab ko jaise ki pataa hi hoga bhagwaan par chadhe koi bhi phul ya maalaa usse kidhar bhi nahi phekaa jaataa hai, usse sirf-or-sirf ganga or yamuna jaise shudh nadiyon mein hi bahaayaa jaataa hai. lekin iss lockdown ke wajase sabhi dhaarmik sthal band the toh koi bhi log mandir gaye hi nahi, toh iss liye yamuna or ganga ki nadiyon ka paani sundar or saaph najar aata hai. Hamaare waatawaran mein waayu pradushan itnne maatra mein kam hua hai ki hum agar 100 miles ke range mein himalaya ko bahut aasaani se dekh saktein hai.

Aur yehi nahi balki Italy ke venice canal ka paani itnna saaph hogaya hai ki uss mein hans phir aa gaye hai. Actually mein hua yu tha ki jo venice canal hai usska paani gandaa hone ke kaaran uss mein rehne waale Hans wahaa se chale gaye the lekin iss corona lockdown ke wajase sabhi log ghar par rehne ke kaaran venice canal kaa paani ek dam saaph ho gayaa hai.

Hum ne lock-down mein bahut se problem ko face kiya hai magar kya aap sab jaantein hai hamaare waataawaran mein maano toh iss lock-down ke wajase recovery ho gaya hai. Jo kaam hum khud apne iss advance technolgy ke madat se nahi kar paaye wo kaam iss corona ke lock-down ne kiya hai. Agar hum isske positive prabhaav ko dekhenge toh hamaaraa najariyaa badal jaayegaa.

Kuch anokhi baatein iss corona lockdown mein aapke sang

Jaisein ki aap sab jaantein hi hai, iss corona mahamaari ke wajase saare desh mein lockdown lag gaya hai. Sabhi ko apna job, business or students ko apna school se door hona pada rahaa hai. Ab ghar baithein-baithein paise kahaan se aayenge ye toh tension darasal hum sab ko hai. Iss corona lockdown mein karein toh kya karein. Ab jo log physical job ya business kar rahethe wo sab log ab shayad hi apna job ya business sambhaal paa rahehonge, nahi toh bahut-se-bahut iss lockdown ke wahjase berojgaar ho gaye hai.

Jo log financially acche hai, unnki toh koi baat nahi lekin jo log financially weak hai unnke liye toh yeh bahut badi chunauti hai. Iss lockdown mein karein toh kya karein. jinhein digitally ghar baithein online kamaane ka source aur knowledge hai wo logo ki toh koi baat hi nahi par jo logo digitally online kamaane ka jariyaa nahi maalum toh unn sabko chintaa toh jarur hogi.

Kya aap sab ko yeh pataa hai, mujhe bhi abhi-bhi digitally kamaane ka jariya nahi maalum aur maalum bhi hai toh kaise kis tarahh karnaa hai yeh nahi maalum. Kehne mein toh bahut sharm aataa hai lekin yeh baat bilkul sach hai. Aaj bhi mai roj online yeh dekhtaa rahtaa hun, ki kaise online kamaaya jaata hai. Chaliye sabse pehle mein aap sab ko apna parichaya detaa hun, mein darasal ek student hun aur mein electronics stream se polytechnic kar rahaahun. Kamaane ka itnaa jyaada echha hai, ki jab online se mera kaam nahi banaa toh mai net pe offline kaise kamaanaa hai ye search karne lagaa.

Lekin iss lokdown mein offline kaam milna bahut hi muskil ki baat hai. yesein hi roj online/offline kaise kamaana hai yeh search kartein-kartein ek din maine dekhaa ki kaam karne mein kaisa sharm. Iss word ko suntein hi mai ekdam se conciously sochne laga. Ab kaise bhi kar ke kamaana hi hai. Ek din ki baat hai roj ke jaise mein shaam ko dukaan se dhudh laane ke liye gaya tha.

Dukaan par jaane ke baad maine uss dudhwaale se dudh maanga, dudhwaalene jaise hi mere haath mein dudh diya waise hi mujhse ye kahaa ki kya tum mere dudh ki delivery karoge. Jaise hi yeh shaabd apne kaano se sunaa, mai sochne lagaa ki kya mai yehi kaam karunga? itna chhota kaam. Uss waqt maine uss dudhwaale se kuch kahaa nahi aur chup-chaap ghar pe aagayaa. Aur ghar pe aakar sabse pehle apni maa se puchaa ki kya yeh dudh ki delivery kaa kaam karnaa chahiye ya nahi. 

Aap jaantein hai meri maa ne kya kahaa mujhse, "Haa kyun nahi din-bhar ghar par baithne se toh achha hi hai, ki tum ye kaam karlo aur kaam kaisaa bhi ho kaam-kaam hota hai. Aur kya tumharaa exercise bhi hojaayega aur tumhaara mood bhi din-bhar fresh rahegaa" yeh baat maa ki sunne ke baad maine socha ha maa bilkul thik hi kehh rahi hai. Actually mai chhote kaam karne se bahut sharmaataa hun lekin maa ne jaise hi kahaa ki kaam-kaam hota hai, bhale hi woh chhota ho ya badaa.

Dusare din jab mai shaam ko dudh laane ke liye gayaa tab uss dudhwaale se kahaa thik hai, yeh kaam mai karunga. Aur jaise aap sabhi ko pataa hi hoga lockdown ke waqt ye dudh ka delivery ka kaam chal rahaa tha, kyun ki ye jarurat waali wastu hai sabki. Toh iss tarahh se maine iss lockdown mein dudh ka delivery kaa kaam shuru kar diya. Aur mujhe ₹4000/- mahine mein miltaa tha.

Aap sab ko  mere baare mein bataane ka ek hi kaaran hai, ki aap bhi agar kamaana chahatein hai toh kuch-na-kuch kijiye jarur khali baithene se acchaa hi hai. Dekhiye mujhe aaj abhi sab pataa toh hai ki digitally online paise kaise kamaane hai lekin lack of experience ki wajase mujhe koi raasta najar nahi aane ke wajase yeh dudh ki delivery jaisa kaam karnaa pada raha hai.

Agar aapko bhi abhi koi digitally online kamaane ke liye nahi aarahaa hai. Toh jyaada sochiye mat jut jaayein offline ke kaam mein, ghar baithne se toh bahut behtar hi hai. Aur haa mai aap sab ko bataa du ki koi bhi kaam badaa aur chhota nahi hota hai, kaam kaam hota hai aur kaam mein koi bhed-bhaav nahi hota hai. Toh aap niraash hoyein nahi koi-na-koi kaam apne najdiki mein dekhen aur shuru hojaayein kamaane ke liye.

Hamein jyaada kar ke ped-paudhe lagaane chaahiye, isse hamarein paryawaran mein ek nayi sudhar aane lagegi

Aap sabhi ko yeh pataa toh jarur hoga, 9th may ko hum sab maatr divas ke roop mein manaatein hai. Hum apni ghar ki maa ke saath ye maatr divas manaatein hai, kya aap dusari maa ko kabhi yaad kartein hai. Aap shaayad samjhe nahin honge ki hum kis maa ki baat kar rahein hai. Darasal hum uss maa ki baat kar rahein hai jis par hum sab jeev-jantu usske sahaare zinda hai, aur apna basera kar rahein hai. Hum apni dharti maa ki baat kar rahaahun. Aaj ke iss yug mein hum, gaon ho ya sahar hum jyaada zamin ke liye hum iss dharti maa ko kitna kast de rahein hai, kya aap ko yeh pataa hai.

Aap sab yeh soch rahein honge ki bhala hamaare wajase dharti maa ko kaisa kast ho rahaa hai. Toh hum aap sab ko bataa de ki, hamaari laalach ke wajase. Hum dheere-dheere zamin ke liye dharti maa ke mann-pasand aur sabse pyari wastu ko hum unsse alag kar rahein hai. Kya aap sab ko malum hai vah konsi wastu hai wo hai "ped-paudhe" ha aapne ne thik suno dharti maa ke sabse adbhut aur pyaari wastu hai "ped-paudhe".

Ped-paudhe sabse anmol wastu hai hamaare dharti maa ke liye, kyun ki issi ped-paudhon ke wajase hamaare dharti maa ke jo mitti hai wo ek jagah par rukaa rehtaa hai. Kyun ki ped-paudhon ka jo roots hota hai wo mitti ko pakad kar rakhtaa hai. Aap sab ne chhoti class mein yeh jarur padhaa hoga "soil erosion" ke baare mein. Soil erosion ko hum hindi mein "Bhu-jharan" kehtein hai. Kyaa aap jaantein hai iss shabda ka matlab kya hota hai, isska matlab hota hai ki jab kisi jagahh par ped-paudhe nahi hote hai aur uss jagahh par hawaa ke tez jhoko ke kaaran mitti ke jo chhote-chhote kan hote hai, wo sab hawaa ke tez jhoko ke wajase se udd jaatein hai. Aur issliye wahaa ke mitti kam ho jaati hai.

Sirf hawaa ke tez jhoko ke wajase hi nahi hota hai "Bhu-jharan" balki bahtein tez paani ke wajase bhi hota hai "Bhu-jharan". Actually mein hota kya hai jab paani ka tez bahaawa hota hai tab uss jagahh par jitne bhi mitti hai woh sab mitti paani ke tez bahaawa ke saath behh jaatein hai, aur issi ko hum hindi mein "Bhu-jharan" kehtein hai aur english mein hum "soil-erosion" kehtein hai.

Aur iss soil-erosion ke kaaran uss jagahh ki mitti kam ho jaati hai, aur ye bahut jyaada maatra mein wahaa ke khetoh ke phaslo mein nuksaan daayak hota hai. uss jagahh ki nami kam ho jaati hai. Aur issi kaaran ke wajase hum uss jagahh par koi bhi phasal ho ya koi bhi prakar ka kheti ho wo achhe se nahi hota hai. Aap ye maan lo ki ye bahut khatarnak hotaa hai "Bhu-Jharan".

Hum iss "Bhu-Jharan" ko kaise Rok saktein hai

Aap sab jaantein hai yeh baat hum ne aapko already bataaya hai agar aapne pehlewaale line ko jaraa gaur se padhaa hoga toh. Hum iss "Bhu-Jhran" ko bahut aasaani se rok saktein hai agar hum ped-paudhon ko kaatna bandh kardein toh. Iss Bhu-Jharan ko rok ne kaa maatra ek hi sabse saral upaaya hai woh hai jyaada se jyaada maatra mein pd-paudhon ko lagaane se. Sirf or sirf ek hi phaayada nahi hoga balki hamein shudha oxygen bhi milega, hamaara waatawaran taaza rahega. Aur samay samay par baarish hogi aur kabhi-bhi jaise sukhaar ki aapdaa nahi aayegi. 

Kya aapko maalum hai jis jagahh par jyaada maatra mein ped-paudhe hote hai uss jagahh par jyaada baarish hota hai. Darasal hota yu hai, ped-paudhe baarish ke baadal ko apne wor khinch lete hai. Aur yehi kaaran hai ki jahaa par jyaada maatra mein ped-paudhe hote hai vahaa jyaada maatra mein baarish hota hai. Iss liye aap sab se yehi nivedan hai ki aap sab jyaada-se-jyaada maatra mein ped-paudhe lagaayein aur  hamaari dharti maa ko phir se khush kardein. Toh chaliye iss maatr divas par hum sab apni iss dharti maa ko tauphe mein dherr saara ped-paudhe arpan karein.
