Análise da estabilidade horizontal de edifícios de aço com múltiplos andares
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Engenharia CivilUTFPR, 2015-12-02)
This paper shows some of the usual techniques for horizontal stabilization of multistory steel structures, with their advantages and disadvantages, and perform linear and nonlinear analysis of the behavior of systems from ...
LMI characterization of structural and robust stability: the discrete-time case
(Elsevier Science IncNew YorkEUA, 1999)
Structural stability of planar quasihomogeneous vector fields
(SpringerBirkhäuser BaselDordrecht, 2014-04)
Let 'H IND.PQM' be the space of all planar (p,q)-quasihomogeneous vector fields of weight degree m endowed with the coefficient topology. In this paper we characterize the set 'Ω IND.PQM' of all vector fields in 'H IND.PQM' ...
Dynamics of aggregate stability influenced by soil management and crop residues
(Taylor & Francis Inc, 2006-01-01)
The type of tillage and crop systems used can either degrade or cause a recovery of the structure of agricultural soils. The objective of this study was to determine the structural stability of the soil using mean weight ...

Insights on the structure and stability of Licanantase: a trimeric acid-stable coiled-coil lipoprotein from Acidithiobacillus thiooxidans
(2014)
Licanantase (Lic) is the major component of the secretome of Acidithiobacillus thiooxidans when grown in elemental sulphur. When used as an additive, Lic improves copper recovery from bioleaching processes. However, this ...
Urbanization, environmental stabilization and temporal persistence of bird species: A view from Latin America
(PeerJ Inc., 2018-12)
Background. A scarcely studied consequence of urbanization is the effect of temporal stabilization of the environment on bird communities. This alteration is thought to dampen environmental variations between day and night, ...
Estabilidade global de edifícios: aplicação do parâmetro de instabilidade α e processo P-Delta
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2016-06-20)
With the increase of the slenderness of the structural elements, made possible by the use of new materials, the study of global stability became indispensable in the design of structural projects. There are many factors ...
