Answer: Arsine
Explanation: Acute ingestion of toxic amounts of inorganic arsine (simplest compounds of arsenic) typically causes severe gastrointestinal signs and symptoms e.g., vomiting, abdominal pain, and diarrhea. These signs and symptoms might lead rapidly to dehydration and shock. Different clinical manifestations might follow, including dysrhythmias (prolonged QT, T-wave changes), altered mental status, and multisystem organ failure that ultimately might result in death.

Sulfur dioxide affects human health when it is breathed in by irritating the nose, throat, and airways to cause coughing, wheezing, shortness of breath, or a tight feeling around the chest. The effects of sulfur dioxide are felt very quickly and most people would feel the worst symptoms in 10 or 15 minutes after breathing it in. Those most at risk of developing problems if they are exposed to sulfur dioxide are people with asthma or similar conditions (Australian Government,...

ctromagnetic Induction HOOSE 2 QUESTIONS: a) A flow meter can be used to measure the speed of blood in situations when a blood essel is sufficiently exposed.Blood is conductive enough that it can be treated as a moving conductor. When it flows perpendicularly with respect to a magnetic field, electrodes can be used to measure a small voltage across the vessel. Suppose the speed of the blood is 0.30 m/s and the diameter of the vessel is 5.6mm. In a...

Under extreme circumstances, there may be a time when incredibly
high blood pressure may cause swelling in the brain. This type of
swelling may occur when no other trauma exists. It certainly
relates to the rate of capillary exchange in the brain. Do you
remember Dave and his swollen ankle? The swelling was edema. In
looking at that case, we also discussed the two main factors
involved with capillary exchange.

A magnetisation transient can occur when a transformer is energised. The protection scheme must not unecessarily trip the transformer by mistaking the inrush for a fault. For a large transformer the better approaches are: Select one: a. Block the protection scheme for a few seconds when the transformer is energised. b. Use a even harmonic or minimum gap time scheme. c. Time the breaker closing to reduce the inrush transient. d. Set the differential protection levels high enough so that a...
