Prime Minister Narender Modi on 27.12.2020 in his last Man-ki-Baat of the year 2020 remembered brave sons of Guru Govind Singh ji namely Zoravar Singh and Fateh Singh who preferred being martyred on 26.12.1704 within the wall built for the purpose rather than adopting Islam at orders of cruel Mughal Emperor Aurangzeb. Nehru-Gandhi Congress in its long regime after independence made all efforts to wash out memories of such unforgettable ones by glorifying members of Nehru-Gandhi family only. Present BJP government should act boldly to re-write school text-books and history-books to make new generation aware about such brave children and other martyrs like Bhagatsingh, Rajguru, Sukhdev and others who were deliberately ignored by Congress dynastically ruled by Nehru-Gandhi family. Insti...

Postal-tariffs have not been revised for last so many years resulting in undesired loss to public-exchequer due to negligible tariff like of 25 or 50 paise still prevailing even though coins in denominations less than rupee one are no more in circulation. Minimum postal-tariff for registered newspapers and ordinary post-cards should be rupee one with these post-cards fetching additional revenue through advertisements printed on postcards. Outdated Inland Letter Cards having lost utility should be discontinued. Thereafter all postal-tariffs (inland and international) should be in multiples of rupees ten. Printed or rubber-stamped post-cards and ordinary mail should have tariff of rupees ten with weight-slabs for mail-articles fixed in multiples of 50 gms rather than of 20 gms at present....

चक्रवर्ती राजगोपालाचारी, यह नाम भारतीय इतिहास का एक ऐसा स्वर्णिम पृष्ठ है, जिससे एक सशक्त जननायक, स्वप्नदर्शी राजनायक, आदर्श चिन्तक, दार्शनिक के साथ-साथ युग को एक खास रंग देने की महक उठती है। उनके व्यक्तित्व के इतने रूप हैं, इतने आयाम हैं, इतने रंग है, इतने दृष्टिकोण हैं, जिनमें वे व्यक्ति और नायक हैं, दार्शनिक और चिंतक हैं, प्रबुद्ध और प्रधान है, वक्ता और नेता हैं। उनकी उपलब्धियों के वैराट्य को देखते हुए उनको दी गयी ‘राजाजी’ की उपाधि उचित है। उन्हें भारतीय राजनीति के शिखर पुरुष कहा जाता है। प्रसिद्ध वकील, लेखक और दार्शनिक थे। वे पहले भारतीय गर्वनर जनरल थे। महान् स्वतंत्रता सेनानी, समाज सुधारक, गांधीवादी राजनीतिज्ञ चक्रवर्ती राजगोपालाचारी को आधुनिक भारत के इतिहास का ‘चाणक्य’ माना जाता है। बीसवीं शताब्दी के भारत के महान् सपूतों की सूची में कुछ नाम हैं जो अंगुलियों पर गिने जा सकते हैं, उनमे...

New Delhi, Dec 07 (India Science Wire): Indian Institute of Technology Mandi(IIT-Mandi) researchers haveproposed a technique to enhance the power output of piezoelectric materials. Piezoelectric materials can be used in floor tiles to generate electricity from human walking, or on roads, where the weight from the vehicles can power road lights and signals. In their study, the researchers have numerically examined the piezoelectric materials and have proposed a new arrangement to enhance the electrical output of these materials when subjected to stress.“Piezoelectric materials can generate electrical energy when a force is applied on them, and are thus extremely useful”, explains Dr Rajeev Kumar, Associate Professors, School of Engineering, IITMandi. However, currently, the electric...

नई दिल्ली, 07 दिसंबर, (इंडिया साइंस वायर): केले की फसल में उकठा रोग के प्रकोप के कारण हर वर्ष किसानों को भारी नुकसान उठाना पड़ता है। उकठा रोग को पनामा रोग या फ्यूजेरियम विल्ट भी कहा जाता है। यह रोग केले की जड़ों में फ्यूजेरियम ओक्सिपोरम एफ.एसपी. क्यूबेंस (Foc) नामक पादप रोगजनक फफूंद के कारण होता है। भारतीय वैज्ञानिक, इस रोग के दौरान फ्यूजेरियम ओक्सिपोरम और केले के बीच आणविक स्तर पर पड़ने वाले परस्पर प्रभावों के बारे में समझ विकसित करने के लिए शोध कर रहे हैं। उनका कहना है कि केले में उकठा के लिए जिम्मेदार रोगजनक फफूंद के बारे में विस्तृत जानकारी इस रोग की रोकथाम के लिए प्रभावी रणनीति विकसित करने में उपयोगी हो सकती है। उकठा रोग होने से पौधों की पत्तियाँ और मुलायम भाग सूखने लगते हैं और उनमें दृढ़ता नहीं रह जाती। इस रोग के कारण केले का तना मुरझाने लगता है और भूमि से सटे तने के हिस्सों...

The Indian Council of Medical Research (ICMR) has recently approved the dry swab direct RT-PCR method which is faster and more convenient than the existing gold standard Reverse transcription-polymerase chain reaction (RT-PCR) test. The method has been devised by a team of researchers from the Centre for Cellular and Molecular Biology (CCMB). The dry swab method is a modification of the RT-PCR test by cutting down a few steps. For RT-PCR, nasal swabs are collected and transported in a tube containing the viral transport medium (VTM) to ensure the stability of the viruses. However, the dry swab method developed by the CCMB research team does not require a VTM. Instead, the swab is collected and sealed in a tube and transported to the laboratory in a dry state. Thus, this method fa...

New Delhi, December 07 (India Science Wire): In a major boost to efforts to promote research to combat antimicrobial resistance (AMR), Bengaluru-based Centre for Cellular and Molecular Platforms (C-CAMP) has signed a Memorandum of Understanding (MoU) with International Health Management Associates (IHMA), a global organisation that has been involved in supporting anti-infective and diagnostic development studies for over 25 years. Under the pact, C-CAMP and IHMA will jointly facilitate microbiology-related studies for clinical trials, surveillance studies, mentorship programmes and other activities with the view to promote new drug and vaccine discovery in the area of anti-infectives and foster new-age diagnostic device development to address the growing problem of antimicrobial r...

A video is going viral on WhatsApp showing Mexican Ambassador in India having an official three-wheeler rather than diplomatic car for official movements in Delhi. Video may be true or not but the message is very important for central and state government together with their public-sector-understandings (PSUs) where especially ordered air-conditioned three-wheelers may replace official cars for those entitled for official cars. Step will not result in big saving of fuel, but will also reduce purchase-cost on vehicles and ever-increasing congestion on roads apart from checking pollution. Introduction of air-conditioned three-wheelers will be popular amongst middle-income small families to switch over from cars to three-wheelers. Otherwise also all possible steps should be taken to discou...

GUWAHATI, 8 December 2020: It is estimated that global water consumption will increase by ≈3,800 km 3 /yr by 2025, and much of this water will have to be obtained from natural systems. Scientists from across the globe have been trying to tackle this crisis by pulling water out of the air. In one such attempt, researchers at the Indian Institute of Technology (IIT) Guwahati have developed novel materials that can efficiently harvest water from humid air. With increasing water scarcity throughout the world, there have been attempts to collect and conserve water through non-traditional means. “Such water-harvesting techniques use the concept of hydrophobicity or water-repelling nature of some materials”, explains Dr Uttam Manna, Associate Professor, Chemistry department and Centre of ...
