What is UV-C technology?

In News:

Ultraviolet-C or UV-C Disinfection Technology will soon be installed in Parliament for the “mitigation of airborne transmission of SARS-COV-2’’.

About the UV-C air duct disinfection system:

Developed by CSIR-CSIO (Central Scientific Instruments Organisation).

The system is designed to fit into any existing air-ducts and the virucidal dosages using UV-C intensity and residence time can be optimised according to the existing space.

The virus is deactivated in any aerosol particles by the calibrated levels of UV-C light.

It can be used in auditoriums, malls, educational Institutions, AC buses, and in railways.

What is UV radiation?

UV radiation is the portion of the Electromagnetic spectrum between X-rays and visible light.

The most common form of UV radiation is sunlight, which produces three main types of UV rays:

Key facts:

UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths.

While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earth’s ozone layer. So, most of the UV rays you come in contact with are UVA with a small amount of UVB.

How is it being used?

UV radiations are normally used to kill microorganisms.

Particularly, UV-C, also known as Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet light to kill or inactivate microorganisms by destroying their nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions and stops their replication.

UVGI is used in a variety of applications, such as food, air, and water disinfection.

Is it safe for humans?

Researchers noted that the device was specifically developed to disinfect non-living things. Therefore, UV-C radiation used in this device could be harmful to the skin and eyes of the living beings.

‘Scene of crime officers’ in Karnataka police

In News:

Karnataka Government is planning to recruit 206 ‘scene of crime officers’ (SoC officers) across the state.

Who are they?

Scene of Crime officers will have a rank equivalent to police sub-inspector and will be part of the Directorate of Forensic Science Laboratories.

The SoC officers will specialise in forensic science as well in identification, collection and preservation of evidence at the scene of the crime.

These officers will be trained investigators, who will undergo training at National Forensic Sciences University in Gandhinagar, Gujarat, and Central Forensic Science Laboratory in Hyderabad.

According to the initial plans by the police department, all districts will have one SoC unit with four to five SoC officials.

Significance:

According to the Karnataka police, this is the first time in the country that dedicated officials will be deployed for evidence collection, a system that exists in advanced countries.

In 1961 in London, the first crime scene officer post was created.

What the Constitution says on Dismissal of govt employees?

In News:

Commission to examine the issue of Sub-categorization

In News:

Cabinet approves Extension of term of the commission constituted under Article 340 of the constitution to examine the issue of Sub-categorization within other Backward Classes in the Central List.

Background:

National Commission for Backward Classes (NCBC) proposed the sub-categorisation of Other Backward Classes (OBCs) back in 2015.

In October 2017, President Ram Nath Kovind, in exercise of the powers conferred by Article 340 of the Constitution, appointed a commission to examine the issue of sub-categorisation of OBCs, chaired by retired Justice G. Rohini, to ensure social justice in an efficient manner by prioritising the Extremely Backward Classes (EBCs).

What is Article 340?

It lays down conditions for the appointment of a Commission to investigate the conditions of the backward classes.

The President may by order appoint a Commission consisting of such persons as he thinks fit to investigate the conditions of socially and educationally backward classes within the territory of India.

Constitutional basis:

Article 14 of the Constitution guarantees equality before the law. That means un-equals cannot be treated equally. Measures are required to be taken for the upliftment of un-equals to bring them on par with the advanced classes.

Article 16 (4) provides that the State can make any provision for the reservation of appointments or posts in favour of any backward class of citizens who, in the opinion of the state, are not adequately represented in the services under the State.

Need for sub- categorization:

Sub categorization of the OBCs will ensure that the more backward among the OBC communities can also access the benefits of reservation for educational institutions and government jobs.

At present, there is no sub-categorisation and 27% reservation is a monolithic entity.
