The textbook states: “The Lumière Brothers of France exhibited their short films in December 1895 at Grande Cafe, Paris.” This is widely recognised as the world's first public commercial film screening. Key film history milestones to distinguish:
- 1877: Eadweard Muybridge's sequential photos of a horse (establishing the optical principles)
- 1889: Thomas Edison developed the Kinetograph camera and Kinetoscope (peepshow viewer — for one person at a time)
- 1893: Kinetoscope marketed in penny arcades (NOT a public projection)
- December 1895: Lumière Brothers' Cinématographe first public screening, Grand Café, Paris (the true birth of cinema as a group experience)
- 1896: Lumières brought films to India (Watson Hotel, Bombay, 7 July 1896)
- 1905: First movie theatre (nickelodeon) opened in Pittsburgh
The distinction between Edison's individual-viewer Kinetoscope and the Lumières' projected Cinématographe is crucial: only the latter created cinema as a shared social experience.
Jones Criteria for Acute Rheumatic Fever (ARF) — 2015 AHA Revision:
Diagnosis requires: evidence of preceding Group A Streptococcal (GAS) infection PLUS:
- 2 Major criteria, OR
- 1 Major + 2 Minor criteria
| Major Criteria | Minor Criteria |
|---|---|
| Carditis (clinical or subclinical/echocardiographic) | Fever (\(\geq 38.5°C\)) |
| Polyarthritis (migratory) | Elevated ESR or CRP |
| Sydenham's Chorea | Prolonged PR interval on ECG |
| Erythema Marginatum | Arthralgia (only if arthritis not counted as major) |
| Subcutaneous Nodules | Elevated WBC |
Mnemonic for Major criteria: JONES — Joints (polyarthritis), Oh (carditis), Nodules, Erythema marginatum, Sydenham's chorea
Treatment:
- Penicillin V × 10 days (eradicate GAS)
- Aspirin for arthritis/carditis
- Corticosteroids for severe carditis
- Secondary prophylaxis: Benzathine Penicillin \(1.2\,\text{MU}\) IM every 3–4 weeks for years (duration depends on carditis severity)
A company has: Ordinary shares $1.00 each: $200,000; Share premium: $80,000; Revenue reserves: $160,000. Changes in order: (1) One-for-one bonus issue; (2) Rights issue of 100,000 shares at $1.40 each. Company wishes to maximise dividends. What are the resulting balances?
Option A is correct.
Bonus issue (200,000 new shares @ $1): Use share premium $80,000 first, then revenue reserves $120,000.
After: Shares $400,000 | Share premium $0 | Revenue reserves $40,000
Rights issue (100,000 @ $1.40): $100,000 to share capital, $40,000 to share premium.
Final: Shares $500,000 | Share premium $40,000 | Revenue reserves $40,000
- B < Be: Be (2s², full subshell) has higher IE₁ than B (2p¹, easier to remove)
- O < N: N (2p³, half-filled, extra stable) has higher IE₁ than O (2p⁴, one paired electron easier to remove)
Option (4) captures exactly these two inversions: Be before B is wrong; N before O is correct. Answer = option (2) per key. Li < B < Be < C < O < N < F < Ne.
