Scale model to measure stress under circular footings resting on sand
(Taylor and Francis Ltd., 2018-10)
This paper presents the results of a series of load tests carried out with a foundation model supported by sand. The aim of this study is to measure the stresses in the soil that occur when applying loads with a circular ...
How does early maternal separation and chronic stress in adult rats affect the immunoreactivity of serotonergic neurons within the dorsal raphe nucleus?
(Taylor & Francis Ltd, 2018-01)
Vulnerability to emotional disorders like depression derives from interactions between early and late environments, including stressful conditions. The serotonin (5HT) system is strongly affected by stress and chronic ...
Determination of Residual Stresses in High Speed Milled Aluminium Alloys Using a Method of Indent Pairs
(Springer, 2009-09)
An improved method of indent pairs is utilised to determine residual stresses in high speed milling specimens of AA 6082-T6 and AA 7075-T6 aluminium alloys. To carry out the measurement procedure, this approach does not ...
Links between fear of humans, stress and survival support a non-random distribution of birds among urban and rural habitats
(Nature Publishing Group, 2015-09-08)
Urban endocrine ecology aims to understand how organisms cope with new sources of stress and maintain allostatic load to thrive in an increasingly urbanized world. Recent research efforts have yielded controversial results ...
Do species' strategies and type of stress predict net positive effects in an arid ecosystem?
(Ecological Society of America, 2017-03)
A proposed refinement to the stress-gradient hypothesis requires consideration of the strategies of the interacting species and the characteristics of the stress factors. While the strength and direction of these interactions ...
Niche dynamics in amphitropical desert disjunct plants: Seeking for ecological and species‐specific influences
(Wiley, 2020-11)
Numerous studies have assessed whether species niches are conserved in geographically separated regions. However, most of them were performed on invasive species, with the limitation that such species have likely not yet ...
Numerical experiments on the determination of stress concentration factors in orthotropic perforated plates subjected to in plane loading
(Techno-Press, 2009-07)
As it is known, laminated composite materials are increasingly used in many technological applications, and in some instance, cutouts must be made into laminated panels for practical reasons, changing the stress distribution. ...
Proteome changes and physiological adaptations of the phytopathogen Xanthomonas citri subsp. citri under salt stress and their implications for virulence
(Wiley Blackwell Publishing, Inc, 2019-06)
The bacterium Xanthomonas citri subsp. citri (Xcc) is responsible for the widely distributed disease citrus canker. In the last years, Xcc has become a model for the study of plant pathogens, and here we used this bacterium ...
Root phospholipids in Azospirillum-inoculated wheat seedlings exposed to water stress
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2006-11)
Azospirillum–plant association is accompanied by biochemical changes in roots which, in turn, promote plant-growth and tolerance to water stress. To shed light on the possible factors underlying these effects, roots from ...
Reductions in Maize Root-tip Elongation by Salt and Osmotic Stress do not Correlate with Apoplastic O2•− Levels
(Oxford Academic Press, 2008-10)
Background and Aims: Experimental evidence in the literature suggests that O2•− produced in the elongation zone of roots and leaves by plasma membrane NADPH oxidase activity is required for growth. This study explores ...
