Bifurcations and aggregation in large scale systems
(IFAC Proceedings Volumes, 1987-08)
This paper deals with the following problem: assume that a qualitative analysis (behaviour modes, bifurcation points, type of atractors .•• ) of a nonlinear dynamical system has been carried out and that afterwards this ...

Isolation of ntrA-like mutants of Azobacter vinelandii
(American Society for Microbiology, 1986)
A number of of chlorate-resistant mutants of Azotobacter vinelandii affected in a general control of nitrogen metabolism were isolated. These mutants could not utilize dinitrogen, nitrate, or nitrite as a nitrogen source. ...

Direct versus sequential four-particle transfer in heavy ion collisions with superfluid nuclei: Sn+Sn reaction
(American Physical Society, 1988)
The direct transfer of four nucleons in reactions with superfluid systems is compared with the feeding of the same final channel by a successive transfer of correlated nucleon pairs. A quantitative analysis is carried out ...

Adaptation of yeast cell membranes to ethanol
(American Society for Microbiology, 1987)
A highly ethanol-tolerant Saccharomyces wine strain is able, after growth in the presence of ethanol, to efficiently improve the ethanol tolerance of its membrane. A less-tolerant Saccharomyces laboratory strain, however, ...

Test of the proton-neutron interacting boson-fermion model in the region around A=190
(American Physical Society, 1986)
We present systematic calculations on nuclei in the region around A=190 within the framework of the proton-neutron interacting boson-fermion model. Energy levels and electromagnetic properties of both positive and negative ...

An analysis of the Iberian lynx predation upon fallow deer in the Coto Doñana, SW Spain
(Ministery of Agriculture, Agricultural Research Administration, for the Organising Committe of the XVIIth JUGB Congress, 1985)
Analysed are 1537 scats of lynxes and 24 carcasses of deer killed by lynxes from 1973 to 1984 at the Doñana Biological Reserve. Lynx predation upon deer is low (0%-8% of the prey). and concentrates in Autumn-Winter, when ...
