About the Bahmani Kingdom

The Bahmani Kingdom was established in 1347 when Ala-ud-din Hassan Bahman Shan revolted against Muhammad Bin Tughlaq of the Delhi Sultanate.
This marked the creation of the first independent Islamic kingdom in South India.
The kingdom covered areas in present-day Karnataka, Maharashtra, and Andhra Pradesh.
Initially, the capital was set in Ahsanabad (Gulbarga) but was later moved to Bidar.
The Bahmani Kingdom had 14 sultans in total, with prominent rulers like Alauddin Bahman Shah, Muhammad Shah I, and Firoz Shah.

How climate change is bringing back the idea of Airships?

Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

Note4Students

From UPSC perspective, the following things are important:

Prelims level: Airships

How climate change is bringing back the idea of Airships?

Why in the News?

Some companies have been working to solve the buoyancy challenge of Airships, a longstanding issue that has hindered their use for cargo transportation.

What are Airships?

Airships are lighter-than-air aircraft capable of controlled powered flight.
They were the first aircraft to achieve this and were considered the future of travel in the early 20th century.
However, as aeroplane technology advanced, the popularity of airships declined due to their technological limitations.
Today, airships are used mainly for:
- Advertising platforms
- Aerial observation for research and military purposes
- Tourism and scenic flights

Note: Buoyancy is the force that makes things float. It acts in the opposite direction to gravity. When an object is placed in a fluid (like air or water), the fluid pushes up against the object, helping it to stay afloat.

How do Airships work?

Airships achieve lift by using lighter-than-air gases within their structure, much like helium balloons.
Early airships used hydrogen due to its lightweight and low cost.
- However, hydrogen is highly flammable, leading to tragic incidents such as the Hindenburg disaster of 1937, which damaged public trust in airships.
Most airships today use helium, a non-flammable gas that is safer than hydrogen.
However, helium is scarce and expensive, costing about $35 per cubic meter (enough to lift just 1 kg).
Challenge with varying Buoyancy:
- Airships require the ability to vary their buoyancy to adjust for weight changes when picking up or dropping off loads.
- Solutions such as releasing and refilling helium are impractical due to helium’s high cost and scarcity.

How Airships are a Promising Solution?

Airships hold potential as low-emission cargo vehicles due to their unique design:

Airships have a high lift-to-drag ratio, meaning they consume far less fuel than aeroplanes for moving the same load.
Companies are exploring the use of ballast to regulate airship buoyancy, a method common in hot air balloons and submarines.
A French company has created a 200-meter “flying crane” airship called LCA60T, which can pick up water as ballast mid-flight, avoiding the need for specialized ground infrastructure.
With concerns about climate change and the aviation industry’s carbon footprint, airships offer a less polluting alternative. They do not burn fossil fuels to lift, making them an eco-friendly choice.

How Vitamin D deficiency can trigger autoimmune conditions?

Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

Note4Students

From UPSC perspective, the following things are important:

Prelims level: Autoimmune Conditions, Vitamin D

Why in the News?

Recent research conducted by scientists at McGill University has shed light on the critical role of vitamin D in maintaining thymus health and its implications for immune function.

About Autoimmune Conditions:

Autoimmune conditions refer to disorders where the immune system mistakenly attacks the body’s own healthy tissues, viewing them as foreign.
Vitamin D plays a role in regulating immune responses and promoting immune tolerance—the body’s ability to avoid attacking its own cells.
It influences T-cells (a type of immune cell) to recognize and tolerate the body’s own tissues rather than attacking them.
The thymus gland trains T-cells to avoid attacking healthy cells. A deficiency in Vitamin D may cause the thymus to age prematurely, reducing its ability to regulate T-cells properly.
- Vitamin D affects certain genetic pathways related to immune function.
- Variations in the vitamin D receptor (VDR) gene may also predispose some individuals to autoimmune diseases, and these individuals might be more sensitive to Vitamin D levels.

What is Vitamin D?

Vitamin D is a fat-soluble vitamin crucial for the body’s ability to absorb calcium, magnesium, and phosphate, which are essential for bone health.
It supports muscle movement, nerve function, and immune system responses. Due to its synthesis in the skin upon exposure to sunlight, it is often called the ‘sunshine vitamin’.
The body naturally produces Vitamin D when skin is exposed to ultraviolet B (UVB) rays from sunlight.
Sources of Vitamin D:
- Fish: Salmon, mackerel, tuna, and sardines are rich in Vitamin D.
- Cod liver oil: A concentrated source, providing 400–1,000 IU per teaspoon.
- Mushrooms: Varieties like portobello contain Vitamin D if exposed to UV light.
- Fortified Foods: Milk, yogurt, orange juice, and cereals often have added Vitamin D.
- Egg yolks: Contain a small amount of Vitamin D.
- Common forms include Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol), especially useful in autumn and winter when sunlight exposure is limited.

Significance of Vitamin D

Bone Health: Essential for calcium absorption, which strengthens bones and prevents osteoporosis.
Muscle and Nerve Function: Supports muscle contractions and nerve signaling between the brain and body.
Immune System: Enhances immune defenses, helping to fight off infections by viruses and bacteria.
Brain Health: May play a role in maintaining cognitive health, especially with aging.
Inflammation and Pain: Helps regulate the body’s response to inflammation and pain.
Blood Pressure: Linked to regulating blood pressure; deficiency is associated with hypertension.

Impacts of Vitamin D Deficiency

Increases the risk of rickets in children (softening of bones) and osteoporosis in adults.
Low levels of Vitamin D are linked to autoimmune conditions like rheumatoid arthritis, lupus, and multiple sclerosis.
Recent studies indicate that Vitamin D deficiency can accelerate thymus aging, leading to immune dysfunction and a higher risk of autoimmune diseases.
Deficiency has been associated with cancer, cardiovascular disease, diabetes, depression, and chronic pain.
Can include fatigue, muscle weakness, bone pain, and depression.
In severe cases, deficiency may cause impaired bone growth and fracture susceptibility.

PYQ:

[2011] Regular intake of fresh fruits and vegetables is recommended in the diet since they are a good source of antioxidants. How do antioxidants help a person maintain health and promote longevity?

(a) They activate the enzymes necessary for vitamin synthesis in the body and help prevent vitamin deficiency.

(b) They prevent excessive oxidation of carbohydrates, fats and proteins in the body and help avoid unnecessary wastage of energy.

(d) They activate certain genes in the cells of the body and help delay the ageing process.
