70 Years of Central Warehousing Corporation (CWC)

• The Central Warehousing Corporation (CWC) celebrated its 70th Foundation Day on March 2, 2026, marking seven decades of contribution to India’s food security and logistics infrastructure.

Central Warehousing Corporation (CWC):

• The Central Warehousing Corporation (CWC) is a Central Public Sector Enterprise (CPSE) under the Ministry of Consumer Affairs, Food & Public Distribution.
• It serves as a premier logistics and warehousing organization supporting India’s food security, agricultural storage, and integrated supply chain management.

Established in:

• 1957 under the Warehousing Corporations Act, 1962 (later governed under Companies Act framework).

Historical Evolution:

• Roots trace back to wartime food administration during World War II, when a separate Food Department was set up in 1942.
• Post-independence restructuring of the Food Ministry (1947–1958) led to the transfer of warehousing functions to the central government.

• To provide scientific storage, handling, and logistics support for foodgrains and essential commodities.
• To strengthen India’s food security framework and reduce post-harvest losses.
• To improve supply chain efficiency and contribute to lowering national logistics costs.

Key Functions:

• Scientific Storage: Construction and management of warehouses and godowns for foodgrains, sugar, fertilizers, and other commodities.
• Logistics & Supply Chain Services: Inland container depots (ICDs), container freight stations (CFSs), and integrated logistics hubs.
• Support to PDS & Food Security: Assists procurement, buffer stocking, and distribution under the Public Distribution System (PDS).
• Custom Bonded Warehousing: Facilitates import-export trade by offering bonded storage and customs clearance support.
• Infrastructure Development: Acquisition and leasing of land for warehousing expansion across states.

Significance:

• Plays a critical role in maintaining buffer stocks and ensuring smooth distribution of essential commodities nationwide.
• Contributes to India’s goal of becoming a top global logistics performer by improving storage efficiency and reducing supply chain bottlenecks.

Oleum Gas

• A major oleum gas leak at Bhageria Industries Ltd in Boisar, Maharashtra, forced the evacuation of over 2,000 residents, including 1,600 students.

About Oleum Gas:

• Oleum, commonly referred to as fuming sulfuric acid, is a highly corrosive chemical consisting of dissolved sulfur trioxide (SO₃) in concentrated sulfuric acid (H₂SO₄). It releases dense white fumes when exposed to moist air.

Chemical Name:

• Oleum (Fuming Sulfuric Acid)
• Chemical representation: H₂SO₄·xSO₃
• When x = 1, the compound is Disulfuric Acid (H₂S₂O₇), also called Pyrosulfuric Acid

Production:

Oleum is produced through the Contact Process, which involves:

• Burning sulfur to produce sulfur dioxide (SO₂).
• Oxidizing SO₂ to sulfur trioxide (SO₃).
• Absorbing SO₃ into concentrated sulfuric acid to form oleum.
• This method avoids directly dissolving SO₃ in water, which would create an uncontrollable acid mist.

Properties of the Gas:

1. Physical Properties:

• Appearance: It appears as dense, white cloudish smoke when leaked into the air.
• Freezing Point: Its freezing point varies strongly with concentration; it can be solid at room temperature or remain liquid as low as zero degree.

2. Chemical Properties:

• Dehydration: It is an extremely strong dehydrating agent, capable of pulling water elements out of sugars to leave pure carbon (the carbon snake reaction).
• Corrosivity: It is highly corrosive but lacks free water to attack surfaces, making it less corrosive to certain metals in its pure form compared to diluted acid.
• Hydration: It has a very high enthalpy of hydration; when SO3 in oleum meets water/moisture, it forms a fine mist of sulfuric acid.

Impact on Health:

• Acute Irritation: Exposure can cause minor to severe eye irritation.
• Respiratory Distress: Hazardous fumes can cause irritation to the respiratory tract; emergency responders use Self-Contained Breathing Apparatus (SCBA) to avoid inhalation.
• Sulfuric Acid Mist: In large releases, it creates a mist of micrometre-sized sulfuric acid particles that are hazardous over wide areas.

Applications:

• Sulfuric Acid Manufacture: Used as an intermediate to produce concentrated sulfuric acid by dissolving SO3 without creating difficult-to-manage mists.
• Explosives: Used in manufacturing explosives like Trinitrotoluene (TNT) to create anhydrous nitration mixtures.
• Organic Chemistry: Acts as a harsh reagent for secondary nitration of nitrobenzene.
• Industrial Transport: Transported in rail tank cars as a safe way to move sulfuric acid compounds between refineries and consumers.

About Geographical Indication (GI) Tag

• A Geographical Indication is a legal recognition for products from a specific territory with qualities, reputation, or characteristics tied to that origin.
• Legal Basis: In India, GIs are regulated by the Geographical Indications of Goods (Registration and Protection) Act, 1999, which came into effect in 2003.
• International Alignment: The law was enacted to comply with the TRIPS Agreement under the World Trade Organisation (WTO).
• Nodal Authority: Geographical Indications Registry in Chennai issues GI tags under the Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry.

Significance:

• GI recognition enhances export value and ensures better price realization for local farmers.
• Supports India’s strategy to diversify agricultural exports under value-added and region-specific branding.

Homemaking Recognised as a Legally Relevant Role with Significant Economic Value

• The Delhi High Court ruled that homemaking is a legally relevant role whose economic value must be considered in maintenance decisions.
• Earning Capacity: Educational qualifications or the ability to work alone cannot justify denying maintenance, as earning capacity differs from actual income.
• Joint Property: Property acquired during marriage qualifies as a joint contribution because a homemaker’s labour builds the savings that fund such purchases.

Status of Homemaking in India

• Notional Income: The Supreme Court ruled that a homemaker’s notional income in motor accident claims must not be lower than the minimum wage for skilled workers.
• Time Poverty: 2nd All-India Time Use Survey found women aged 15-59 spend 305 minutes daily on unpaid domestic work, 3.5 times that of men.

New Study on Bacterial Gene Regulation

• A recent study by the Bose Institute and Rutgers University challenged the “sigma (σ) cycle” model of bacterial gene regulation.

About Sigma Cycle

• Old Model: The sigma cycle was considered the universal mechanism for bacterial gene transcription, based on studies in Escherichia coli.
• Transcription is the process by which a specific DNA segment is copied into a complementary RNA strand by the enzyme RNA polymerase (RNAP).
• Mechanism: A sigma factor (helper protein) binds to RNAP to initiate transcription and detaches during DNA-to-RNA copying.

More About the New Study

• Key Finding: In Bacillus subtilis, the principal sigma factor (σA) remains attached to RNA polymerase throughout the transcription process.
• Model Challenged: This persistence proved that the sigma cycle is not a universal rule for bacterial gene regulation.
• Key Implications: The finding can aid targeted antibiotic design and improve microbial engineering for efficient biofuel, bioplastic, and therapeutic production.
