-Question of the Month-
 

Dived or dove, which is correct?

From the Guide to Grammar and Style by Jack Lynch. at Rutgers

Dive, Dived, Dove.

The traditional past-tense form of dive is dived.

Although dove is common in speech, it's probably safer to stick with dived in writing.

See also Sneak, Sneaked, Snuck. [Entry added 12 Jan. 2005.]

Also, the British only use "dived", but Canadians and Americans use "dived" and "dove".

And, verb conjugation is :
to dive I dive; you dive; he, she, it dives; we dive; you dive; they dive I dived/dove; you dived/dove; he, she, it dived/dove; we dived/dove; you dived/dove; they dived/dove dived/dove (Ex: They have dived too deep.)


Finally,

The American Heritageฎ Dictionary of the English Language: Fourth Edition. 2000.

ETYMOLOGY: Middle English diven, from Old English dfan, to dip, and from dfan, to sink; see dheub- in Appendix I.

USAGE NOTE: Either dove or dived is acceptable as the past tense of dive. Usage preferences show regional distribution, although both forms are heard throughout the United States. According to the Dictionary of American Regional English, in the North, dove is more prevalent; in the South Midland, dived. Dived is actually the earlier form, and the emergence of dove may appear anomalous in light of the general tendencies of change in English verb forms. Old English had two classes of verbs: strong verbs, whose past tense was indicated by a change in their vowel (a process that survives in such present-day English verbs as drive/drove or fling/flung ); and weak verbs, whose past was formed with a suffix related to ?ed in Modern English (as in present-day English live/lived and move/moved ). Since the Old English period, many verbs have changed from the strong pattern to the weak one; for example, the past tense of step, formerly stop, became stepped. Over the years, in fact, the weak pattern has become so prevalent that we use the term regular to refer to verbs that form their past tense by suffixation of ?ed. However, there have occasionally been changes in the other direction: the past tense of wear, now wore, was once werede, and that of spit, now spat, was once spitede. The development of dove is an additional example of the small group of verbs that have swum against the historical tide.

RECIPE OF THE MONTH
 

Lobster and Corn Chowder

 

Ingredients:

• 3 live hard-shell lobsters (1 1/4 pounds each)
• 3 medium ears yellow or bi-color corn
• 4 ounces slab (unsliced) bacon, rind removed and cut into 1/3-inch dice
• 4 tablespoons unsalted butter
• 1 large onion (10 ounces) cut into 3/4-inch dices
• 2 to 3 sprigs fresh thyme, leaves removed and chopped (1 teaspoon)
• 2 teaspoons Hungarian paprika
• 1 1/2 pounds Yukon Gold, Prince Edward Island, or other all-purpose potatoes, peeled and cut into 3/4-inch dice
• 1 1/2 cups heavy cream (or up to 2 cups if desired)
• Kosher or sea salt and freshly ground black pepper


For garnish:

• 2 tablespoons chopped fresh Italian parsley
• 2 tablespoons minced fresh chives


Directions:

1. Fill an 8 to 10-quart stockpot two-thirds full with ocean water or tap water that is heavily salted. Bring to a rolling boil. One at a time, holding each lobster by the carapace (the protective shell), carefully drop it into the water. Cook for exactly four minutes from the last time the lobster went in. Using a pair of long tongs, remove the lobsters from the pot and let them cool to room temperature.

2. Pick all the meat from the tails, knuckles and claws. Remove the intestinal tract from the tail and the cartilage from the claws. Dice the meat into 3/4-inch cubes. Cover and refrigerate until ready to use. Using the carcasses (bodies), and leftover shells, make a lobster stock (Recipe is below). The stock will take about 1 1/2 hours to cook. Strain the stock; you should have 4 cups.

3. Meanwhile, husk the corn. Carefully remove most of the silk by hand and then rub each ear with a dry towel to finish the job. Cut the kernels from the cobs and reserve. You should get about 2 cups. Break the cobs in half and add them to the simmering stock.

4. Heat a 4 to 6-quart heavy pot over low heat and add the bacon. Once it has rendered a few tablespoons of fat, increase the heat to medium and cook until the bacon is crisp golden brown. Pour off all but 1 tablespoon of the fat, leaving the bacon in the pot.

5. Add the butter, onion and thyme and saut้, stirring occasionally with a wooden spoon, for about 8 minutes, until the onion is softened but not browned. Add the paprika and cook 1 minute longer, stirring frequently.

6. Add the potatoes, corn kernels, and the reserved lobster stock. The stock should just barley cover the potatoes; if it doesn't, add enough water to cover. Turn up the heat and bring to a boil. Cover the pot and cook the potatoes vigorously for about 12 minutes, until they are soft on the outside but still firm in the center. If the broth hasn't thickened lightly, smash a few potatoes against the side of the pot and cook a minute or two longer to release their starch.

7. Remove the pot from the heat; stir in the lobster meat and cream, and season to taste with salt and pepper. If you are not serving the chowder within the hour, let it cool a bit, then refrigerate; cover the chowder after it is chilled completely. Otherwise, let it sit at room temperature for up to an hour, allowing the flavors to meld.

8. When ready to serve, reheat the chowder over low heat; don't let it boil. Use a slotted spoon to mound the lobster, onions, potatoes, and corn in the center of large soup plates or shallow bowls, making sure they are evenly divided, and ladle the creamy broth around. Sprinkle with the chopped parsley and minced chives.

Makes about 10 cups; serves 10 as a first course or five or six as a main course.

Ingredients for Lobster Stock:

• 2 pounds lobster carcasses and shells
• 2 quarts water
• 1 cup dry-white wine
• 1 cup chopped tomatoes with their juice (fresh or canned)
• 2 medium onions, thinly sliced
• 2 stalks celery, thinly sliced
• 2 small carrots, thinly sliced
• 4 cloves garlic, crushed
• 4 sprigs fresh thyme
• 2 dried bay leaves
• 1/4 teaspoon fennel seeds
• 1 teaspoon black peppercorns
• Kosher or sea salt


Directions for Lobster Stock:

1. Split the lobster carcasses lengthwise and remove the head sac from each one. Place the carcasses, shells and tomalley (lobster's liver) in a 6 to 8-quart stockpot, cover with the water, and bring to a boil, skimming the white scum from the surface of the stock. (Using a ladle and a circular motion, push the foam from the center of the outside of the pot, where it is easy to remove.) Reduce the heat so the stock is cooking at a fast, steady simmer.

2. Add the wine, tomatoes, onions, celery, carrots, garlic, thyme, bay leaves, fennel seeds and peppercorns, and let the stock simmer and cook down for about 1 hour. Add a little water if the stock falls below the lobster shells.

3. Season the stock lightly with salt. Taste for a rich flavor. If it seems light, simmer for about 20 minutes longer. Strain the stock with a fine-mesh strainer. If you are not going to be using it within the hour, chill it as quickly as possible. Cover the broth after it has completely cooled and keep refrigerated for up to three days, or freeze for up to two months. Makes about 1 quart.

Dive tip


Oxygen Toxicity

The effects of oxygen are increased at depth so that the maximum PO2 in diving is 1.6 ATA, and this is achieved at 218 fsw breathing air, 132 fsw breathing 32% O2, and 20 fsw breathing 100% O2.

This is due to the effects of Dalton's Law which states that on descent, the partial pressure of all component gases increase in the same ratio as the total pressure. this results in the creation of the elevated pO2 that causes the convulsions of O2 toxicity and is the direct cause of nitrogen narcosis and along with Boyle's law, is the cause of decompression sickness.

All O2 treatments using 100% O2 are given at 60 feet or shallower, except for gas gangrene and CO poisoning. This effect is also the limiting factor in the use of nitrox (increased O2 percentages) in increasing the bottom time of "tech" divers.

The effect on the central nervous system ( the Paul Bert effect), results in:

  • muscle twitching and spasm
  • nausea and vomiting
  • dizziness
  • vision (tunnel vision) and hearing difficulties (tinnitus)
  • twitching of facial muscles
  • irritability, confusion and a sense of impending doom
  • trouble breathing, anxiety
  • unusual fatigue
  • incoordination
  • convulsion.
    Convulsion at depth in water usually results in drowning or arterial gas embolism and is prevented by not using oxygen breathing with SCUBA and by limiting oxygen exposure with hyperbaric oxygen therapy 100% O2 greater than 60 FSW.

    Factors increasing susceptibility to O2 toxicity include:

  • Increasing exposure time
  • Increasing depth
  • Increasing the percentage of inspired O2 (As in nitrox mixtures)
  • The simple act of immersion setting off the diving reflex
  • Exercise increasing the metabolic rate
  • Increased CO2 in the tissues (May be due to cerebral vasodilation)
  • Cold stress (Shivering is a form of exercise)Systemic diseases that increase the metabolic rate (such as thyroid diseases)
    Pulmonary oxygen toxicity ( Lorraine Smith effect) is a direct time /dose relationship on the lungs caused by a direct effect of O2 on the lungs, blockage of airways, increased CO2, pulmonary surfactant changes , enzyme interference and an inert as effect. The best treatment is prevention and removal of pure O2 at the first signs of toxicity.
