Analytical, numerical and experimental studies on the Semi-Active Friction Tendon
(Elsevier, 2017-09)
For controlling vibrations, a Semi-Active Friction Tendon (SAFT), which consists of a semi-active friction damper and an auxiliary spring that are linked to the structure by a cable, is studied experimentally, numerically ...
On the assumed inherent stability of semi-active control systems
(Elsevier, 2018-03)
Vibration control systems are usually classified into: passive, active and semi-active. Semi-active control systems are based on formerly passive mechanical devices, such as springs and dampers, whose characteristics are ...
Spatial heterogeneity provides organic matter refuges for soil microbial activity in the Patagonian steppe, Argentina
(Pergamon-Elsevier Science Ltd, 2009-06)
In arid and semi-arid ecosystems that are frequently classified as water limited, it is unclear how spatial and temporal variability of vegetation and climate could affect microbially-mediated soil processes. Our objective ...
Debris flows triggered from melt of seasonal snow and ice within the active layer in the semi-arid Andes
(John Wiley & Sons Ltd, 2020-01)
Debris flows triggered from rapid melt of seasonal snow, and/or ice within the active layer have not been studied in periglacial areas of the semi-arid Andes. Therefore, through a representative watershed we investigated ...
Semi-interpenetrated, dendritic, dual-responsive nanogels with cytochrome c corona induce controlled apoptosis in HeLa cells
(Elsevier Science, 2018-09)
The use of thermoresponsive nanogels (NGs) allows the controlled release of therapeutic molecules upon a thermal switch. Usually, this strategy involves the use of temperature increase to activate cargo expulsion from ...
A Semi-Field Approach to Testing Botanical Insecticides. Effects of Natural and Analogues Annonaceous Acetogenins on Spodoptera frugiperda Smith (Lepidoptera: Noctuidae)
(SCIRP, 2021-11)
Annonaceous acetogenins enclose a large number of biological activities, among which the insecticidal stands out. Spodoptera frugiperda is a pest that affects corn crops among others and has a great capacity to develop ...
Corn starch-based coating enriched with natamycin as an active compound to control mold contamination on semi-hard cheese during ripening
(Elsevier, 2019-06-19)
The effectiveness of natamycin supported in corn starch-based films to control environmental molds (mainly Penicillium spp) activity that could colonize the surface of semi-hard cheese during ripening, was evaluated. The ...
Tidal action and macroalgal photosynthetic activity prevent coastal acidification in an eutrophic system within a semi-desert region
(Academic Press Ltd - Elsevier Science Ltd, 2021-08-05)
Nutrient input drive macroalgal blooms and increases in photosynthetic activity in coastal ecosystems. An intense macroalgal photosynthetic activity can increase the surrounding pH and it could prevent the acidification ...
Effects of highly-diluted bioactive compounds (HDBC) on growth, survival and physiological condition of Penaeus vannamei shrimp reared in a commercial farm
(Pontificia Universidad Católica de Valparaíso, 2022)
