The Amchang Wildlife Sanctuary is a wildlife sanctuary located on the eastern fringe of Guwahati, Assam, India. Amchang’s habitat is dominated by tropical moist deciduous forest with semi- evergreen forest in depressions and river- valleys. It is known for its elephants which have become isolated with no movement with other elephant-populations. The first published information of these elephants was found in 1985 The sanctuary has other mammals such as Chinese pangolin, slow loris, Assamese macaque, rhesus monkey, hoolock gibbon, leopard, leopard cat, jungle cat, sambar, barking deer, red serow, Malayan giant squirrel, crestless Himalayan porcupine FACTS –> The Union Cabinet approved four projects under the India Semiconductor Mission (ISM). Two of the projects will be in Bhubaneswar in Odisha, and one each will be in Punjab and Andhra Pradesh. The firms behind the four new projects are SiCSem (which will make a silicon carbide integrated facility in Info Valley, Bhubaneswar); Continental Device India Private Limited, which will expand its existing “discrete semiconductor manufacturing facility” in Mohali; 3D Glass Solutions Inc., which will set up a “vertically integrated advanced packaging and embedded glass substrate unit” in Bhubaneswar; and Advanced System in Package (ASIP) Technologies, which will set up a semiconductor unit in Andhra Pradesh, with the location yet to be chosen.

 

 

Muon & g-factor Basics Muon: elementary particle, similar to electron but 207 times heavier. Has spin → behaves like a small magnet. Magnetic strength expressed by g- factor. Classical theory: g = 2; quantum effects cause a small deviation (anomalous magnetic moment). In physics, it typically refers to the Landé g- factor, which describes the magnetic properties of particles and nuclei. Measurements of the g-2 of the muon were first made at CERN with a definition of 4,000 ppm. Fermilab started measuring g-2 in 2017 and quickly reached a precision of 0.460 ppm. Fermi National Accelerator Laboratory, located in Batavia, Illinois, near Chicago, is a United States Department of Energy national laboratory specializing in high-energy particle physics
