6. CMPDIL Invents New Dust Control Technology

Tags: Environment Science and Technology

In order to minimize and control the fugitive dust in mining areas, Central Mine Planning and Design Institute Limited (CMPDIL), Ranchi has invented a “System and Method for Controlling Generation and Movement of Fugitive Dust ''.

An overview of the news

  • CMPDIL, Ranchi is a consultancy subsidiary of Coal India Limited.

  • It has obtained a patent for the invention in December, 2022 (Patent No. 416055).

  • This system can be used in mines, thermal power plants, railway sidings, ports, construction sites where coal or other mineral/fugitive material is stored under open sky.

About invention

  • The invention relates to the synchronized application of windbreak (WB) and vertical greenery system (VGS) for reducing generation and dispersion of fugitive dust. 

  • WB and VGS are positioned in the upwind and downwind directions with respect to the blown dust source, respectively.

  • WB reduces the speed of the oncoming wind towards the source and hence, reduces the intensity of the ambient air to pick up dust while it blows over the source.

  • The VGS acts as a filter and reduces the amount of residual dust moving towards the receptors in the downward direction along with the air.

  • Therefore, there is a significant reduction in the dust concentration in the ambient air at various receptors located in the down-wind direction.

What is Fugitive Dust?

  • Fugitive dust is a form of particulate matter that contributes to air pollution.

  • It refers to the dust particles which like to run in the air without a directed place.

  • It is produced from various sources that come in contact with the air.

9. World's first vaccine for honeybees approved for use by United States

Tags: Science and Technology International News

The US Department of Agriculture (USDA) has approved the world's first insect vaccine, which has been developed to protect bees from a devastating bacterial disease.

An overview of the news

  • US researchers have developed a vaccine to target a disease called American foulbrood.

  • The disease is caused by Paenibacillus larval bacteria and once it reaches a bee population, it has the potential to completely destroy the colony.

  • Dalil Freitak of the University of Helsinki and his colleagues discovered an important egg yolk protein called vitellogenin.

  • This fundamental discovery laid the groundwork for a new type of insect vaccine, and the team's first target was honey bees.

Effectiveness of vaccine

  • The vaccine works by binding to the vitellogenin protein in inactivated bacterial cells so that when consumed by the queen bee it can be transferred directly to her larvae.

  • This vaccine is given to the queen bees in the form of royal jelly. She swallows it, and fragments of the vaccine get deposited in her ovaries.

  • After exposure to the vaccine, immunity develops in the developing larvae.

  • A successful clinical trial demonstrated that the vaccine is both safe and effective.

  • Progeny from a vaccinated queen bee are much less likely to contract bacterial disease.
