Definicija: Podajanje, razširjanje informacij, znanja, postopkov.

Definicija: Glej intelligence cycle.

Definicija: Potovanje zvočnih valov po atmosferi s hitrostjo, ki je neodvisna od njihove razsežnosti. Hitrost je odvisna od prenosnega sredstva in je sorazmerna s kvadratnim korenom absolutne temperature v posameznem sredstvu.

Definicija: The travelling of acoustic waves in the atmosphere with a speed independent of their amplitude. The speed only depends on the acoustic medium and is proportional to the square route of the absolute temperature for any given medium.

Definicija: 1.) Širitev puščavskih razmer kot rezultat človekovega delovanja ali podnebni sprememb. 2.) Proces povzročitve škode, ki se odraža v širjenju puščavskih tal v suhih in polsuhih območjih. Izgine rastlinska plast, spremeni se tekstura, zmanjša vsebnost hranil in zniža rodovitnost prsti. Dezertifikacija prizadeva življenje treh četrtin svetovnega prebivalstva, 70 % vseh sušnih predelov in eno četrtino Zemljinega površja. Obstaja več razlogov za dezertifikacijo, vendar so za večino izmed njih krive človekove dejavnosti, čezmerno pašništvo, krčenje gozdov, slabo upravljanje pokrajine in izčrpavanje naravnih virov. V Agendi 21 je zapisano, da je prioriteta v boju z dezertifikacijo oblikovanje preventivnih ukrepov za območja, ki še niso ali pa so malo degradirana.

Definicija: 1) The development of desert conditions as a result of human activity or climatic changes. 2) The process of land damage which allows the soil to spread like a desert in arid and semi-arid regions. There is a loss of vegetative cover and the soil deteriorates in texture, nutrient content and fertility. Desertification affects the lives of three-quarters of the world's population, 70% of all drylands and one quarter of the total land area of the planet. There are many reasons for desertification, but the majority are caused by human activities, overgrazing, deforestation, poor land management and over-exploitation. Agenda 21 states that the priority in combating desertification should be establishing preventive measures for lands that are not yet, or are only slightly, degraded.

Definicija: distribution of information from one source to many recipients

Definicija: Vertikalna ali horizontalna razpršitev onesnaževal v zrak in v okolje.

Definicija: Vertikalna ali horizontalna razpršitev onesnaževal v zrak in v okolje.

Definicija: V okoljskem kontekstu se izraz nanaša na širjenje onesnaževal zraka, ki je odvisno od vrste vira onesnaženja (točkasti, linijski ali razpršeni vir), hitrosti vetra in njegove smeri. Širjenje je lahko aktivno ali pasivno.

Definicija: In an environmental context, the term refers to the dispersion of air pollutants and depends on the type of pollution source (point source, line source, diffuse source), the wind velocity and the wind direction. Distribution can be active or passive.

Definicija: Zvok, ki seširi z vibriranjem trdne strukture.

Definicija: Sound that travels over at least part of its path by means of the vibration of a solid structure.

Definicija: Postopek, s katerim je motnja z ene točke razširjena do druge točke, ki je bolj oddaljena od vira, brez pretoka samega materiala po nosilcu. Primeri so gibanje elektromagnetnih valov, zvočni valovi, hidrodinamični valovi v tekočini in vibracije v trdnih telesih.

Definicija: Process by which a disturbance at one point is propagated to another point more remote from the source with no net transport of the material of the medium itself; examples include the motion of electromagnetic waves, sound waves, hydrodynamic waves in liquids, and vibration waves in solids.

Definicija: diplomatic, intelligence, and military efforts to combat the proliferation of weapons, including both weapons of mass destruction (WMD), long-range missiles, and certain conventional weapons. Counter-proliferation focuses on intelligence, law enforcement, and sometimes military action to prevent their acquisition.

Definicija: Kurativni in preventivni ukrepi, ki so uvedeni proti dezertifikaciji in vključujejo namakanje, saditev dreves in zatravljanje, postavitev ograj, ki preprečujejo širjenje in oblikovanje sipin, ter previdno upravljanje z vodnimi viri.

Definicija: Remedial and preventive actions adopted against desertification include irrigation, planting of trees and grasses, the erection of fences to secure sand dunes, and a careful management of water resources.
