Liquid nitrogenous fertilizers
The Journal of Agricultural Science, 1959The results show that liquid fertilizers generally gave lower yields of dry matter than conventional solid fertilizers in four experiments on grassland. In seven trials, on autumn wheat, spring wheat, sugar beet and kale, the efficiencies of the two forms of fertilizer were similar.Liquid fertilizers containing ammonia must be injected into the soil ...

Inhalation of liquid nitrogen vapor
Annals of Emergency Medicine, 1982A case of accidental inhalation of liquid nitrogen vapor is reported. The patient, a 29-year-old man, developed acute burns of his lips and oropharynx and presented with signs and symptoms of acute upper airway distress within an hour of the injury. The patient underwent emergency tracheostomy and was placed on intravenous dexamethasone and ampicillin.

ASME 1966 Citrus Engineering Conference, 1966
“The orange juice tastes a little funny this morning.” With these immortal words, the chief purchasing agent of my household was ready for a permanent, if not lethal boycott of one of the major name brands of frozen Florida orange juice concentrate. She had opened the can the same morning, and she was right — it did have a hint of “5-day old” taste ...

Review of Scientific Instruments, 1955
A low-pressure laboratory liquefier having a capacity of 45 to 50 liters per hour is described. A combination of old and new features makes possible continuous operation without an attendant. Impurities such as water, carbon dioxide, and oil are eliminated automatically by reversing exchangers.

Benign skin lesions such as solar and seborrhoeic keratoses, viral warts, and skin tags can be treated successfully by cutaneous cryotherapy. Complications are infrequent if the correct technique is used and local anaesthetic usually is unnecessary. Liquid nitrogen (boiling point -196 degrees C) is the usual freezing agent but carbon dioxide snow (-79 ...

LIQUID NITROGEN FOR DERMATOSES
Journal of the American Medical Association, 1954To the Editor: —Having had experience with liquid nitrogen in the treatment of various dermatoses, I have often been questioned regarding the practical factors in its use. Liquid nitrogen is noninflammable and has a boiling point of -195 C (-319 F). Its therapeutic value is due to its ability to freeze the skin and cause blistering of varying degrees,

SUBSTITUTE FOR LIQUID NITROGEN
Archives of Dermatology, 1953Liquid nitrogen cryotherapy is an almost indispensable modality for those who have learned its virtues. However, it may not be available at any time for some and not always available for others. An effective substitute is carbon dioxide slush. Though slower in producing freezing than liquid nitrogen, it is more rapid, more adaptable to irregular ...
