"spread distance" is correct and usable in written English.
It can be used to describe the action of keeping a physical or emotional distance from someone or something. For example, "In an attempt to protect the passengers, the airline asked passengers to spread distance between themselves and other passengers in the waiting area."
Compared to rural areas, peri-urban areas appeared to have a higher density of equine premises (4.66 premises km−2 versus 0.80 premises km−2), longer epidemics (95 days versus 87 days), more infected premises (393 versus 339) and a shorter spread distance (1.27 km versus 2.38 km).
The macropores of hollow cores (~91 nm) could store up the electrolyte and close the spread distance between the electrolyte and materials.
No direct relationship was observed between the spread distance and the human population density.
(ii) Spatially represent the maximal AIV spread distance by this species (under the assumption that infected ducks were not subjected to behavioral modifications reducing flight abilities).
We also calculated the correlation between spread distance and the human population density in the infested area, and we calculated the invasion probability as a function of the human population density.
Since 2001, the number of new records of the nematode was multiplied by a factor of 5 and the spread distance by a factor of 2. We combined a diffusion model to describe the short distance spread with a stochastic, individual based model to describe the long distance jumps.
These clusters were analysed individually to parameterise key epidemic measures: cumulative incidence, incidence rate, effective reproduction rate, nearest neighbour spread distances, epidemic length and the number of infected premises.
The analyses revealed that the incipient phase was characterized by high regional synchrony and long defoliation spread distances per year, whereas the epidemic and crash phases were characterized by much lower regional synchrony and a much shorter spread of defoliation.
Factors influencing the warm jet spreading distance of an impinging jet ventilation (IJV) system, which is operated in heating mode, are studied and multiple regression analysis is used to develop multivariate regression models for the estimation of the spreading distance.
The larger the required spreading distance there is, the more restrictions there are on the studied variables.
With the regression models established for the warm air spreading distance, the optimized combination of these variables for satisfying the design requirement is determined.
