    Daily Prelims 22nd November 2023

    1) Nitrogen-9: Scientists have recently discovered nitrogen-9 nuclei which contains 7 protons and 2 neutrons.  

    • It is an unusually high proton-to-neutron ratio.  
    • This disparity has a critical effect on the isotope’s stability, influencing its decay processes as well as overall behaviour.  
    • It only exists for one billionth of a nanosecond.  
    • Nitrogen -9 is an isotope of nitrogen.  
    • Atoms with the same number of protons but different numbers of neutrons are called isotopes.  
    • Scientists are hopeful of expanding our current understanding of nuclear theory and quantum mechanics by this study 

     

    2) E Prime layer: As per new study, a new layer called “E prime layer” at the outermost part of Earth’s core is a result of surface water penetrating deep into the planet  

    • This alters the composition of the metallic liquid core’s outermost region proposes.  
    • This latest research suggests that tectonic plates carrying surface water have transported it deep into the Earth over billions of years.  
    • This led to the formation of a hydrogen-rich, silicon-depleted layer at the outer core.  
    • Discovery enhances our comprehension of Earth’s internal mechanisms. 

     

    3) Eklavya Model Residential Schools (EMRSs): President of India inaugurated EMRS in Odisha.  

    • EMRS started in 1997-98 to impart quality education to ST children in remote areas to enable them to avail opportunities in high and professional educational courses and get employment in various sectors.  
    • Each school has a capacity of 480 students, catering to students from Class VI to XII.  
    • EMRSs are set up in States/UTs with grants under Article 275(1) of Constitution.  
    • Its nodal ministry is Ministry of Tribal Affairs.  
    • Minimum of 15 acres of Land is required for establishing EMRSs 

     

    4) Cyclone Midhili: According to recent IMD update, the cyclone storm Midhili, after crossing Bangladesh coast, weakened into a deep depression and later into a depression.  

    • Cyclonic storm is cyclonic disturbance in which the maximum average surface wind speed is in range of 34 to 47 knots (62 to 88 kmph).  
    • In deep depression, maximum sustained wind speed lies in the range 28 to 33 knots (50 to 61 kmph).  
    • Depression is a cyclonic disturbance in which maximum sustained surface wind speed is between 17 and 33 knots (31 and 61 kmph) 

     

    Places in News: 

    1) Argentina (Capital: Buenos Aires): 

    • Javier Milei won the Argentina’s Presidential elections.  
    • Political Boundaries  
    • Country of South America, covering most of southern portion of continent.  
    • Bounded by Chile (south and west), Bolivia and Paraguay (north), and Brazil, Uruguay, and Atlantic Ocean (east).  
    • Geographical features  
    • Terrain: Rich plains of Pampas in northern half, flat to rolling plateau of Patagonia in south, rugged Andes along western border.  
    • Highest Point: Cerro Aconcagua  
    • Major rivers: Parana, Paraguay, Uruguay etc.
