To decrease the alkalinity

Gypsum is calcium sulfate. The most common form of it is the dehydrate which means that each molecule of calcium sulfate has two water molecules associated with it. It is expressed as CaSO42H20. The other form called gypsum anhydrite has no water.

Regular use of gypsum is essential to the sustainability of most irrigated soils. Irrigated land eventually leads to sodicity and salinity unless extreme care is taken. Gypsum is a key ingredient for the maintenance of agriculture on many types of soil and over a wide pH range, including sodicity.

Gypsum, in addition to prevention and correction of sodicity, include: greater stability of soil organic matter, more stable soil aggregates, improved water penetration into soil, and more rapid seed emergence.

Mouth to mouth resuscitation

What should you do?

• Call an ambulance: dial 000 and tell the emergency services that someone has had a cardiac arrest.
• Act fast: get someone to call for skilled help. A person who has had a cardiac arrest won’t survive unless the blood starts pumping and the body gets a supply of oxygen very quickly.
• Start CPR (cardiopulmonary resuscitation). CPR involves mouth-to-mouth breathing and external heart massage through the chest (chest compressions).

Currents and tides

River deltas form when a river carrying sediment reaches either (1) a body of standing water, such as a lake, ocean, or reservoir, (2) another river that cannot remove the sediment quickly enough to stop delta formation, or (3) an inland region where the water spreads out and deposits sediments. The tidal currents also cannot be too strong, as sediment would wash out into the water body faster than the river deposits it.

Mughal painting was essentially a court art; it developed under the patronage of the ruling Mughal emperors and began to decline when the rulers lost interest. The subjects treated were generally secular, consisting of illustrations to historical works and Persian and Indian literature, portraits of the emperor and his court, studies of natural life, and genre scenes.
