Abstract: The present invention, entitled “Non-explosive and non-flammable nitrogenous fertilizer based on ammonium nitrate”, is a chemical fertilizer intended, mainly, for the contribution in nitrogen input into agricultural soils, essentially in granule form. Said product solves or minimizes many of the main problems found in the chemical fertilizer industry, including the following: the use of fertilizers in the production of explosives for terrorism purposes; the release of noxious gases and greenhouse gases, such as NOx and ammonia; the contamination of water tables by the run-off of chemical substances, especially nitrates, owing to rainfall; and chemical fertilizers having fixed content in terms of nitrogen percentage. The present invention, “Non-explosive nitrogenous fertilizer based on ammonium nitrate”, can contain a variable nitrogen concentration of 30% to 40%.

Abstract: A method and system are disclosed for providing a multi-user encrypted environment to each of a plurality of user groups. Each user group has a plurality of corresponding users. The system comprises a plurality of virtual network interface cards, each for authenticating and communicating according to a corresponding encryption scheme. The system further comprises a user group database associating each of the plurality of virtual network interface cards to a given user. The system also comprises a routing unit connected to the plurality of virtual network interface cards and to the user group database for dynamically associating a given user of a given user group to a corresponding virtual network interface card according to the user group database to thereby provide the corresponding encrypted environment.
