​​What is an Auxanometer? How does it Work?

Image
An auxanometer is an apparatus for measuring increase or rate of growth in plants.  In case of an arc-auxanometer, there is a wire fixed with the plant apex on one end and a dead-weight on the other. It passes over a pulley which has a pointer attached to it.   When the plant's height increases, the pulley rotates and the pointer moves on a circular scale to directly give the magnitude of growth. The "rate of growth" is a derived measurement obtained by dividing the length of growth measured by the auxanometer, by the time said measurement took. Sensitive auxanometers allow measurement of growth as small as a micrometer, which allows measurement of growth in response to short-term changes in atmospheric composition. Auxanometers are used in the laboratory, the field, and the classroom. Koningsberger invented the auxanometer.

​​Why are local disks in computers labelled with alphabets C, D, E and not with A and B?

Image
Have you seen a floppy? Floppies were a type of disk storage used earlier before the current system of storage came into existence. Floppy disk drives were named with the letters A and B. When hard disk drives became standard in most computers, they were logically labeled 'C' since the first two letters were already used for these floppy drives. Though floppy disk drives are no longer widely used, hard disks are still labeled from 'C' onwards.

Poultry economics:  The global poultry market reached a value of nearly $319.2 billion in 2019, having grown at a compound annual growth rate (CAGR) of 5.5% since 2015, and is expected to grow at a CAGR of 6.1% to nearly $405 billion by 2023. The market is expected to grow at a CAGR of 7.2% to nearly $465.7 billion by 2025, and at a CAGR of 6.8% to $645.7 billion by 2030. Challenges to the poultry industry:  Poultry immunity, health, and production are several factors that challenge the future growth of the poultry industry. Consumer confidence, product quality and safety, types of products, and the emergence and re-emergence of diseases will continue to be major challenges to the current situation and the strategic future of the industry. Foodborne and zoonotic diseases are strictly linked with poultry. Eradication, elimination, and/or control of foodborne and zoonotic pathogens present a major challenge to the poultry industry. In addition, the public health hazards of consu...
