For this reason, data concerning the extension of medium-tension (200 110 kV) distribution power lines were recorded as an adequate surrogate of the low-tension wiring network extension in Spain.
Every two months searches of the ground under 100 km of medium-tension power line in and around territories of Spanish imperial eagle were made during 1980 1982 [22], [22].
We compared the number of birds found electrocuted per nesting pair and per km of medium-tension power lines at both regional and local levels, between the two periods using a Mann-Whitney non-parametric test [27].
Interestingly, data show a significant change in the number of birds found electrocuted per nesting pair and per km of medium-tension power lines both in Andalucía (Mann-Whitney, U = 58.50, Z = 2.75, P = 0.006) and in Doñana (Mann-Whitney, U = 43.50, Z = 3.56, P<0.001) (Figure 3).
Mr. Dingman is a composer eager to show that he can satisfy basic requirements: ballads, medium-tempo tension and dense contrapuntal cross-hatching.
The use of rubber bands as a tension medium proved to be a limiting factor since the beginning of the experiments due to the quick degradation of its mechanical properties.
Attempts to establish defined growth conditions by altering medium composition, oxygen tension, inclusion of reducing agents, and various combinations of amino acids, vitamins, growth factors, and detergents have so far failed to support growth of K. radiotolerans.
Besides the fact that P. aeruginosa absolutely needs a functional flagella, a low surface-tension medium and the production of rhamnolipids, very little is known about the regulatory features of swarming motility.
The proposed theory is also applied to a revisit of the classic problem of stress concentration around a cavity in a micromorphic medium subjected to isotropic tension at infinity, for which some conclusions made in early studies are revised.
Three standard test systems for liquid/liquid extraction recommended by the European Federation of Chemical Engineering EFCEE) but without the respective transfer component have been chosen for the investigations: toluene/water, n-butyl acetate/water, and n-butanol/water, representing systems with high, medium, and low interfacial tension.
