What are Strategic and Non-strategic Sectors of India?
An industry is considered strategic if it has large innovative spillovers and if it provides a substantial infrastructure for other firms in the same or related industries.
Earlier, the strategic sectors were defined on the basis of industrial policy.
The government classified Central Public Sector Enterprises (CPSEs) as ‘strategic’ and ‘non-strategic’ on the basis of industrial policy that keeps on changing from time-to-time.
According to this, the Strategic sector PSUs are:

Arms & Ammunition of defence equipment
Defence aircraft & warships
Atomic energy
Applications of radiation to agriculture, medicine.
Railways
Banking, insurance, defence, and energy are likely to be part of the strategic sector list. All other PSUs apart from the strategic sectors fall under Non-strategic Sector including Power Discoms.

Madhubani Paintings

Madhubani art (or Mithila painting) is a style of Indian painting, practised in the Mithila region of Bihar.
This painting is done with a variety of tools, including fingers, twigs, brushes, nib-pens, and matchsticks and using natural dyes and pigments.
It is characterized by its eye-catching geometrical patterns.
It was traditionally created by the women of various communities in the Mithila region of the Indian subcontinent.
This painting as a form of wall art was practised widely throughout the region; the more recent development of painting on paper and canvas mainly originated among the villages around Madhubani.
It is these latter developments that led to the term “Madhubani art” being used alongside “Mithila Painting.”
Its features
It uses two-dimensional imagery, and the colours used are derived from plants. Ochre, Lampblack and Red are used for reddish-brown and black, respectively.
It mostly depicts people and their association with nature and scenes and deities from the ancient epics.
Natural objects like the sun, the moon, and religious plants like tulsi are also widely painted, along with scenes from the royal court and social events like weddings.
Generally, no space is left empty; the gaps are filled by paintings of flowers, animals, birds, and even geometric designs.
Madhubani art has five distinctive styles: Bharni, Kachni, Tantrik, Godna and Kohbar.
This painting has also received a GI (Geographical Indication) status.

Explanation:

Haloarchaea’ microbes
Haloarchaea or halophilic archaea is a bacteria culture which produces pink pigment and is found in water saturated with salt.
The increased salinity and pH facilitated the growth of halophilic microbes, mainly Haloarchaea.
Basically, it is the biomass of these microbes and because of that, the surface of the water turned red or pink and as soon as the biomass subsided, the colour disappeared.
The scientist said the colour of the lake is now returning to original as the rainy season has kicked in, allowing dilution of the water.
Initially, it was thought for the red-pigmented Dunaliella algae due to which the water might have turned pink.
Because of that, the salinity and pH/alkalinity levels have also come down and green algae have started growing in the water body.

Explanation:

Reading Article 191(2) and 10th Schedule
Article 191(2) declares that a person shall be disqualified from being a member of the legislative assembly or legislative council of a state if he is so disqualified under the Tenth Schedule.
The Tenth Schedule to the Constitution contains “provisions as to disqualification on ground of defection”.
Tenth Schedule also fixes the relationship between a member and a political party which selected him as a candidate.
It also provides one of the grounds for disqualification: “If he voluntarily gives up his membership of such political party”.
The decision as to disqualification is left to the absolute discretion of the Speaker.
Constitutional morality and 10th Schedule
Tenth Schedule brings to the fore the need to emphasise “constitutional morality”.
Constitutional morality means “strict adherence to the core principles of constitutional democracy”.
So, Constitutional transgressions by MLAs coming through a “party platform” to serve the people for five years (Article 172), cannot be accepted.
In so doing, these MLAs forget the oath, taken under Article 188 of the Constitution to bear true faith and allegiance to the Constitution of India as established by law.
Legislators do not have absolute freedom to behave in any way they like.
