Water blankets

Because phosphorus is transported and stored under a water blanket, phossy water is a raw waste material at phosphorus-consuming plants. Another source of phossy wastewater results when reactor contents (containing phosphorus) are dumped into a sewer line due to operator error, emergency conditions, or inadvertent leaks and spills. 

The containment of phossy water from phosphorus transfer and storage operations is an important control measure in the phosphorus-consuming sub-category B. Although displaced phossy water is normally shipped back to the phosphorus-producing facility, the usual practice in phosphorus storage tanks is to maintain a water blanket over the phosphorus for safety reasons. 

For the first 1-2 h post-surgery, the rabbit is placed on a heated water blanket (Gaymar Industries, Solid State T pump, Orchard Park, NY) to prevent hypothermia, as anesthetics interfere with normal temperature regulation. 

Place the body of the animal on a water blanket, through which temperature controlled water is circulated to maintain the temperature of the animal. 

Procedure Pre-equilibrate the Substrate Solution, the Sodium Deoxycholate Solution, and about 50 mL of water to 40° in the water bath. Transfer 10 mL of the Substrate Solution to the thermostated titration vessel. Add 5 mL of the Sodium Deoxycholate Solution and 10 mL of deionized water. Blanket the cell with nitrogen and equilibrate for approximately 5 min. Using the Automatic Titrator filled with 0.1 N Sodium Hydroxide Solution, adjust the pH of the solution to 8.0 0.05. Monitor the consumption (if any) of sodium hydroxide for 5 min as a blank. Refill the Automatic Titrator. Add 0.1 mL of Sample Solution containing between 1 and 8 units of activity and start the Automatic Titrator. Record the sodium hydroxide consumption for at least 5 min. 

Fig. 7.4. The proton beam strikes the lead target generating neutrons which are moderated in the surrounding heavy water blanket. Molten salt carrying fissile material for heat generation and electric power production circulates in the heavy water blanket through double-walled pipes. Some of this power drives the accelerator. Nuclear waste including that produced in the molten salt is also circulated through the blanket in a separate loop and transmuted to stable and short-lived nuclides which are extracted and...

Extensive experience has proved that a bundle of smooth tubes continuously flooded by massive quantities of water will not develop encrustations provided the water is properly treated and the surface temperature does not exceed 65 C. A continuous water blanket over the tubular surfaces prevents precipitation of dissolved minerals. Cocurrent flow of water and air provides better operation. 

Humanitarian relief supplies typically comprise multiple products such as food, water, blankets, medicine, and shelter. In their review, Torre et al. (2012) discuss models for the delivery of multiple commodities with differing transportation costs and demands. Balcik et al. (2008) explicitly model the difference between single-use perishable items and multi-use non-perishable items, with demand backlogging for non-perishable items and demand lost for perishable items. 

During cardiac arrest, surgery, and strokes, body temperature is lowered, which reduces the amount of oxygen needed by the body. Some methods used to lower body temperature include cooled saline solution, cool water blankets, or cooling caps worn on the head. How many kilojoules are lost when the body temperature of a surgery patient with a blood volume of 5500 mL is cooled from 38.5 °C to 33.2 °C (Assume that the specific heat and density of blood is the same as for water, 1.0 g/mL.)...
