Food frequency questionnaire-derived estimates of relative intakes of vitamins K in one northern European country suggest that for that population, about 90% of total vitamin K intakes are provided by K 1, about 7.5% by MK-5 through MK-9 and about 2.5% by MK-4; [citation needed] the intense smell and strong taste of nattÅ appear to make this ...
Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues.

Food storage in refrigerators may not be safe unless there is close adherence to temperature guidelines. In general the temperature should be maintained at 4 °C (39 °F) or below but never below 1 °C (34 °F). [8] Safe storage times vary from food to food and may depend on how the food has been treated prior to being placed in the refrigerator.
In turn, animals provide much of the meat eaten by the human population, whether farmed or hunted, and until the arrival of mechanised transport, terrestrial mammals provided a large part of the power used for work and transport. A variety of living things serve as models in biological research, such as in genetics, and in drug testing.
Thermal storage medium in power generation systems. Sodium and potassium nitrate salts are stored in a molten state with the solar energy collected by the heliostats at the Gemasolar Thermosolar Plant. Ternary salts, with the addition of calcium nitrate or lithium nitrate, have been found to improve the heat storage capacity in the molten salts ...

The Coolgardie safe is a low-tech food storage unit, using evaporative cooling to prolong the life of whatever edibles are kept in it. It applies the basic principle of heat transfer which occurs during evaporation of water (see latent heat and heat of evaporation).
