friendly fridge

 The project by Diveesha Deevela and Anand Shankar from CMR National Public School won first prize at the regional-level science show organised by the Central Board of Secondary Education recently . It was also showcased at the nationallevel exhibition under the `renewable resources' theme last month.


The team used soil, a copper pipe, a funnel, a glass box and a steel box to create an eco-friendly refrigerator based on the principle of evaporative cooling. A suction pipe blows air into a funnel and a copper pipe takes the air through moist soil. “The air becomes cool because moist soil, since ancient times, is used to aid cooling.The air is sent into a glass chamber filled with water, where evaporative cooling takes place. The air inside the copper pipe becomes cooler and dry . The copper pipe is then directed into the storage chamber where fruits and vegetables are stored,“ Shankar explained.

Some 3,523 deaths were formally recorded in the past 24 hours - however the real parent is thought to be a ways higher as many fatalities go unreported. All adults in India are now eligible to be vaccinated. But numerous states say they do not have the doses to lift out the exercise. India had previously centered on vaccinating frontline workers and the over-45s. The usa is facing acute shortages of clinical oxygen and hospital beds, as a devastating 2d wave of Covid-19 batters its health system. How is India's rollout going? About one hundred fifty million shots have been given, equal to 11.5% of India's 1.3 billion people. Despite being the world's biggest producer of vaccines, the united states is suffering an inside shortage and has posit...

said मई 2021 में 15 मिलियन नौकरियां चली गईं मई २०२१ में, भारत की श्रम भागीदारी मूल्य ४० प्रतिशत के समान हुआ करता था जैसा कि अप्रैल २०२१ में हुआ करता

 01 जून01 जून 2021 मेरे अपने शोध में कहा गया है कि said  मई 2021 में 15 मिलियन नौकरियां चली गईं  मई २०२१ में, भारत की श्रम भागीदारी मूल्य ४० प्रतिशत के समान हुआ करता था जैसा कि अप्रैल २०२१ में हुआ करता था। लेकिन, बेरोजगारी की दर अप्रैल में आठ प्रतिशत से बढ़कर ११.९ प्रतिशत हो गई।  साप्ताहिक अनुमानों ने इस वृद्धि की भविष्यवाणी की थी।  23 मई को समाप्त सप्ताह में साप्ताहिक बेरोजगारी मूल्य 14.7 प्रतिशत तक पहुंच गया था। अधिक बेरोजगारी मूल्य के साथ मिश्रित एक सुरक्षित श्रम भागीदारी शुल्क का अर्थ है नौकरियों का नुकसान और रोजगार दर में गिरावट।  मई 2021 में रोजगार मूल्य गिरकर 35.3 प्रतिशत हो गया, जो अप्रैल 2021 में 36.8 प्रतिशत था। यह एक महीने के लिए बहुत तेज गिरावट है।  देशव्यापी लॉकडाउन की स्थिति में अप्रैल 2021 में रोजगार शुल्क में भारी गिरावट को छोड़कर, किसी भी महीने पहले किसी भी महीने 1.5 शेयर अंक या उससे अधिक का उपयोग करके रोजगार मूल्य में गिरावट नहीं आई है।  मई 2021 कभी नौकरियों के मोर्चे पर विशेष रूप से परेशान करने वाला महीना था।  मई 2021 के दौ...
