Batch Contacting (Dispersed Phase in Batch)
Both fluids are mixed in a single vessel.
No continuous flow; the reaction occurs over time.
Suitable for small-scale or laboratory operations.
Simple setup, but difficult to scale up.
Co-current Flow
Both fluids flow in the same direction.
Contact time is limited, but mixing can be effective.
Used when reaction time is short or fast kinetics.
Counter-current Flow
Fluids flow in opposite directions.
High mass
Ramjet engine, also known as a Ram engine, is a type of air-breathing jet engine that operates by using the engine’s forward motion to compress incoming air without the need for rotating compressor blades. It has no moving parts and works efficiently at supersonic speeds (above Mach 1).
Working Principle: •Air enters the inlet at high speed due to the aircraft's motion. •The air is compressed and slowed down in the inlet. •Fuel is injected and ignited in the combustion chamber. •The
.🦅 KAISERREICH + PRE-WWI CONTEXT (1890–1918)
Wilhelmine militarism: Kaiser Wilhelm II’s obsession with military prestige alienated socialist and democratic factions. He expanded the navy via the 2nd Naval Law (1900), provoking a costly arms race with Britain.
Authoritarian constitutional monarchy: The Chancellor was unelected, answerable only to the Kaiser, not the Reichstag — creating a democratic façade masking autocracy.
Rapid industrialisation: By 1914, Germany overtook Britain in steel
War Guilt Clause (Article 231)
Germany accepted sole responsibility for WWI, despite the Fischer Thesis (1961) later arguing that German militarism had long-term war aims, the clause ignored broader Allied responsibility.
Psychological humiliation: Germans called the Treaty a “Diktat” — a dictated peace — fueling Dolchstosslegende (stab-in-the-back myth), used by the Nazis to discredit Weimar.
Clause used to justify £6.6 billion reparations, equivalent to 2% of Germany’s GDP annually until
This line is from the short story "The Doll’s House" by Katherine Mansfield, describing the Burnell children’s admiration of the new doll’s house, especially the lamp inside it.
The lamp in the doll’s house becomes a symbol of beauty & perfection to the children. Their admiration is almost spiritual, as it fills them with ecstasy—an intense
oral hypoglycemic agents- Oral hypoglycemic agents (OHAs) are medications taken by mouth that help lower blood sugar levels in people with type 2 diabetes. They work by stimulating the pancreas to produce more insulin, improving the body's sensitivity to insulin, or slowing down the absorption of glucose from the digestive tract.
Types of Oral Hypoglycemic Agents:
Sulfonylureas:
These stimulate the pancreas to release more insulin (e.g., glipizide, glyburide).
Meglitinides:
Beasts of every land and clime,
Hearken to my joyful tiding,
Of the golden future time.”**
These lines are from the song "Beasts of England" in George Orwell’s allegorical novella Animal Farm. The song is introduced by Old Major, a visionary boar, who shares his dream of an animal utopia where all creatures are free from human oppression.:
Old Major begins the song by addressing all animals regardless of their region (“land and clime”). He

George Orwell’s Animal Farm is a brilliant allegorical novella that uses animals on a farm to represent political figures and ideologies. It is rich with symbolism, serving as a powerful critique of totalitarianism, particularly Stalinist Russia. Orwell uses characters, events, and objects symbolically to mirror the events of the Russian Revolution of 1917 and its aftermath.
