खनन और खनिज उद्योगों में पर्यावरणीय स्थिरता विषय पर विशेषज्ञों का मंथन

खनन और खनिज उद्योगों में पर्यावरणीय स्थिरता  विषय पर विशेषज्ञों का मंथन पर्यावरणीय स्थिरता मानव समाज के निरन्तर अस्तित्व, समृद्धि और स्वास्थ्य के लिए मूलभूत शर्त है। हमारी न्यू जनरेशन को स्पीड और टेक्नोलॉजी पर ध्यान केंद्रित करना होगा ताकि भविष्य को सुनहरा बनाया जा सके। उक्त विचार मुख्य अतिथि श्री एमपी सिंह, प्रधान मुख्य अभियंता, केंद्रीय विद्युत प्राधिकरण विद्युत मंत्रालय भारत सरकार, नई दिल्ली ने व्यक्त किए श्री सिंह भूपाल नोबल्स स्नातकोत्तर महाविद्यालय में भूविज्ञान विभाग द्वारा "खनन और खनिज उद्योगों में पर्यावरणीय स्थिरता" विषय पर आयोजित दो दिवसीय राष्ट्रीय कॉन्फ्रेंस के समापन पर बोल रहे थे। दो दिवसीय राष्ट्रीय कान्फ्रेंस का भव्य समापन सम्मानित अतिथि प्रो विनोद अग्रवाल सदस्य, भारत सरकार नई दिल्ली स्थित MOEFCC की विशेषज्ञ मूल्यांकन समिति, (सि एण्ड टीपी) अपने उद्बोधन में कहा कि पर्यावरण स्थिरता सरकार और समाज दोनों की जिम्मेदारी है। वर्तमान में खनन उद्योग विभिन्न प्रावधानों एवं कानूनों के तहत कार्य कर रहा है ताकि पर्यावरण को सुरक्षित रखा जा सके। आयोजन सचिव डॉ. हेमंत सेन न...

Dipole in electric field | Electrostatics


    Electric field

  • The space around a charged particle in which another charge experience a force is known as electric field.

    • Electric field due to a circular loop of charge

  • This is a linear charge distribution in which the charge is distributed along the circumference of the ring or circular loop.
  • If observation point lies on the centre of the loop, then the electric field internsity at this point i.e., at the centre of the loop will be zero.
  • If observation point lies very far from the centre of the loop then the value of electric field will be same as the electric field due to a point charge. It means in this case the circular loop behaves as a point charge for the observation point.

    • Electric field due to an infinitely long straight uniformly charged wire

  • In this article the charge is distibuted along the length of the wire.
  • The electric field at any point due to infinitely long straight wire varies inversely with distance from the wire.

    • NOTE

  • The present lecture is a bilingual lecture, in which every step is explained in Hindi and in English language. Electric field is very important in electrostatics. In the present lecture the electric field due to circular loop of charge, and the electric field due to an infinitely long straight wire is also explained in a well systematic way.

Phase space and density function | Statistical mechanics

Phase space and density function Phase space or 𝚪 space In classical mechanics the position of a point particles is described in terms of three Cartesian coordinates x, y, z. And the state of motion of particle is described in terms of velocity component ẋ, ẏ, ż or momentum coordinates p x , p y , p z . We imagine a 6-d space in which the six coordinates are x, y, z and p x , p y , p z are marked along six mutually perpendicular axes in space. The combined position and momentum space is known as phase space or Γ space . A point in the phase space represents the position and momentum of the particle at some particular instant. Density function Let a classical system has a large number of molecules (N) occupying a large volume V. Generally N = 10 23 molecules and V = 10 23 molecular volumes or N → ∞ and V → ∞ N/V = v ; here v = a specific volume, which is a finite number. The system will be regarded as isolated in the sense that the ener...
