कौनोतोरी (सफ़ेद सारस) प्रयोग क्या है
जापान ने शुक्रवार को कौनोतोरी नाम का स्पेस कैप्सूल अंतरिक्ष में भेजा जिसका काम अंतरिक्ष कचरे को साफ करना है जो पृथ्वी के चक्कर लगा रहें है |
अंतरिक्ष कचरा या स्पेस जंक छोटे बड़े अंतरिक्ष यान उपग्रह या किसी अंतरिक्ष मिशन के अवसिस्ट है जो अब कार्य नहीं कर रहे और अंतरिक्ष में तेजी से घूम रहे है | ये वर्त्तमान अंतरिक्ष यानो के लिए भारी खतरा बने हुए है ,इसलिए इस कचरे को साफ करना बेहद जरुरी हो गया है इसी दिशा में जापान ने एक कदम उठाया है ,इस लिए उसने कौनोतोरी नाम का कप्सुल अंतरिक्ष में भेजा है ताकि इस दिशा में प्रयोग किया जा सके |
इसके लिए कैप्सूल सात सौ मीटर मेटैलिक लाइन का प्रयोग करेगा जो की एक विद्युतिये तार का काम करेगा यह अल्मुनियम और स्टेनलेस स्टील से बना हुआ जाल है | इसकी मदद से कचरे की गति को कम करने का प्रयास किया जायेगा ताकि वह अंततः पृथ्वी के वायुमंडल में घुसकर नष्ट हो जाये |

फिक्र न कर
कहते है की असफलता ही सफलता की कुंजी है ,ये बात तो बहुत छोटी सी है लेकिन सफलता का राज इसमें छिपा है | कोई भी सब कुछ सीख कर पैदा नहीं होता ,सब यही सीखते है इसी दुनिया में , यहाँ आदमी सिखने के लिए ही पैदा होता है | हाँ ये बात अलग है की कोई बड़ा जल्दी सीख लेता है और कोई थोड़े समय में ,और हम सिखने के क्रम में कितनी बार हारते है ,असफल होते है और अंततः सीख लेते है समझिए सफल होते है | शायद यही बात प्रतियोगिता , परीक्षा के लिए भी लागु होता है हम हमेशा सीखते है हारकर भी ,
इसलिए कर्म किये जा ,फल की तू फिक्र न कर ||
सिने में तूफान छुपा है ,
आँखों में आसमान है |
दुनिया हो मेरी मुठी में
ऐसे ही अरमान है ||
कस्ती लगेगी किनारे
ऐ मन तू फिक्र न कर |
आगे देख चलता रह ,
रुकने की तू जिक्र न कर ||
जिन्दा है तू तो संघर्ष कर ,
मंजिल ही तेरा सुकून है |
तू जिन्दा है ,इस धरती पर ,
जब तक तुझमे जूनून है ||

जिद
एक सूनापन सा है आँखों में ,
दिल में एक तन्हाई सी है |
कुछ कचोटता है सिने में ,
दिल की खुद से बेवफाई सी है |
जीवन की राहें रूकती नहीं ,
और जीनें की जज्बा है की झुकती नहीं |
लौ सुलगती रही है उठने को ऊपर,
पर झुकाने को निचे ,बारिश है की रूकती नहीं ||
चोट भले ही थोड़ी खानी पड़े ,
पर राह - ए मंजिल बनानी पड़ेगी ||

over more than several big industries . online market is also evolving as big finance
activities
what is the reason behind so fast growth of online
marketing ?
1.I think the increasing user of smart phones and
purchasing capacity is main cause but it is fact online stores is like a market
in your hand and as like you are always in market and you shop more than
before.
2. Online stores gives so many discounts and thus
the stuff you buying is cheaper than that in the conventional market.
3. Home delivery, people have not to go anywhere and
product came at your door step
It is clear that the coming time online market is
going to increase further and it will benefit people a lot.
Now a day some
online super market is also in the market . online market is very good idea but
we have to be alert also because some time the stuff came at your doorstep is
different from what you buy so be alert and enjoy shopping
