Slugs traps

Net the crop before the fruits ripen. This will exclude birds, but squirrels and raccoons may also take the fruit. Slugs love ripening strawberries. Encourage natural predators, and put down slug traps, or use a biological control see p.97) if necessary. 

Metaldehyde (272), the cyclic tetramer of acetaldehyde and common active ingredient in snail and slug traps and in the chemical control of molluscs <82Mi 926-0l>, has been reviewed in terms of toxicity <85MI 926-02). 

Winter wheat chiefly attacked. Often worse after oilseed rape. Use slug traps to check likely risk with a bait such as chicken layers mash (not slug pellets). A catch of 4 slugs/trap suggests a high risk of damage. 

Here, we refer to small amounts of water rather than large slugs that could damage the trays. Often the water will boil overhead and be drawn off in the overhead accumulator bootleg (water drawoff pot). However, if the column top temperature is too low, the water is prevented from coming overhead. This plus too hot a bottom temperature for water to remain a liquid will trap and accumulate water within the column. The water can often make the tower appear to be in flood. 

Traps in the wet glycol power piping send alternate slugs of glycol and gas to the pump. 

Section provides opposite sprue opening of the injection mold, used for trapping cold slug. 

Water hammer (also known as hydraulic shock) occurs in two distinct ways when the flow of liquid in a pipeline is suddenly stopped, for example, by quickly closing a valve [13], and when slugs of liquid in a gas line are set into motion by movement of gas or condensation of vapor. The latter occurs when condensate is allowed to accumulate in a steam main, because the traps are too few or out of order or in the wrong place. High-pressure mains have been ruptured, as in the following incident. 

The gas zone—A gas bubble is trapped between consecutive slugs, riding on top of the liquid film. 

The present study investigates the adsorption and trapping of polymer molecules in flow experiments through unconsolidated oil field sands. Static tests on both oil sand and Ottawa sand indicates that mineralogy plays a major role in the observed behavior. Effect of a surfactant slug on polymer-rock interaction is also reported. Corroborative studies have also been conducted to study the anomalous pressure behavior and high tertiary oil recovery in surfactant dilute-polymer systems(ll,12). 

The only practical method for the measurement of specific hydrocarbons is by gas chromatography (GC), which can be automated, but is expensive and often used as a laboratory analyzer. Certain specially prepared columns can be used to adsorb specific hydrocarbon classes. For atmospheric hydrocarbons, a common method is to pass a sample of air through a small freeze-out trap, sweep out the air with helium, and then warm the trap and introduce the condensables into the GC column in one concentrated slug. 

If there are shiny slime trails on the remain-ing leaves, slugs and snails are at work. Sprinkle wood ashes or diatomaceous earth around plants, or trap the pests in shallow pans filled with stale beer and empty traps daily.
