The stem xylem of Patagonian shrubs operates far from the point of catastrophic dysfunction and is additionally protected from drought- induced embolism by leaves and roots
(Wiley, 2013-03)
Hydraulic architecture was studied in shrub species differing in rooting depth in a cold desert in Southern Argentina. All species exhibited strong hydraulic segmentation between leaves, stems and roots with leaves being ...
Strong hydraulic segmentation and leaf senescence due to dehydration may trigger die-back in Nothofagus dombeyi under severe droughts: a comparison with the co-occurring Austrocedrus chilensis
(Springer Verlag Berlín, 2014-07-20)
Die-back was observed in South America temperate forests during one of the most severe droughts of the 20th century (1998–1999). During this drought Austrocedrus chilensis trees survived, whereas trees of the co-occurring ...
Hydraulic architecture and photoinhibition influence spatial distribution of the arborescent palm Euterpe edulis in subtropical forests
(Oxford University Press, 2014-06)
Physiological characteristics of saplings can be considered one of the most basic constraints on species distribution. The shade-tolerant arborescent palm Euterpe edulis Mart. is endemic to the Atlantic Forest of Argentina, ...
Direct measurement of hydraulic properties in developing berries of Vitis vinifera L. cv Shiraz and Chardonnay
(Australian Society of Viticulture and Oenology, 2005)
Hydraulic differences along the water transport system of South American Nothofagus species: Do leaves protect the stem functionality?
(Oxford University Press, 2012-07)
Hydraulic traits were studied for six Nothofagus species from South America (Argentina and Chile), and for three of these species two populations were studied. The main goal was to determine if properties of the water ...
Functional relationships between leaf hydraulics and leaf economics in response to nutrient addition in subtropical tree species
(Oxford Univ Press, 2013-11)
Leaves can be both a hydraulic bottleneck and a safety valve against hydraulic catastrophic dysfunctions, and thus changes in traits related to water movement in leaves and associated costs may be critical for the success ...
Análise do crescimento da confiabilidade dos segmentos de uma máquina de lingotamento contínuo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Especialização em Engenharia da ConfiabilidadeUTFPR, 2017-11-10)
In a steelmaking plant, the decision making for maintenane results optimization are almost always based on the experience of professionals and supported by methodologies and tools, such as Pareto, associated with the classic ...
Dynamic three-dimensional finite element analysis of orbital trauma
(2021-10-01)
This study comprises a dynamic finite element (FE) analysis of the mechanisms of orbital trauma, specifically buckling and hydraulic theories. A digital model of the orbital cavity - including the eyeball, fatty tissue, ...
Simulação numérica de trocadores de calor multitubulares equipados com fitas helicoidais externamente aos tubos
(1998-03-01)
Classical shell-and-tube heat exchangers are usually equipped with segmental baffles. These baffles serve two basic functions: (a) they provide tube supports, thereby preventing or reducing mechanical problems, such as ...
