Grazing Modulates the Multiscale Spatial Structure of Dryland Vegetation. [PDF]
Glob Chang BiolWe studied how grazing pressure affects plant spatial patterns in drylands by using satellite images, field plant size and abundance data, and a mathematical model. We found that increasing grazing pressure has opposite effects on vegetation spatial structure to those of aridity, which might be explained by the fact that grazing decreases plant size ...

Materials and Corrosion, Volume 74, Issue 6, Page 818-830, June 2023., 2023 Hollow wire corrosion of stainless steel ropes from mooring installations applied in seawater is introduced. Martensite distribution in the austenite and crystallographic texture resulting from the production technology of the cold‐drawn wires are identified as decisive for this kind of corrosion.

Materials and Corrosion, Volume 73, Issue 11, Page 1788-1799, November 2022., 2022 The effect of welding processes on the corrosion behavior of CuAl10Fe5Ni5 and CuMn12Al8Fe4Ni2 was studied. The microstructures of the welded samples were characterized by metallography using two chemical agents and examined by optical and scanning electron microscopy.

Journal of Engineering Education, Volume 111, Issue 4, Page 813-851, October 2022., 2022 Abstract Background Recent advances in technology and computer simulation have expanded the use of virtual manipulatives in engineering education. However, especially in disciplines in which tactile concepts (e.g., force) are included, it has been claimed that learning could be compromised by substituting physical materials with computer simulations ...

Estudios Geologicos, 2010 Los áridos silíceos se caracterizan por reaccionar con el hidróxido cálcico liberado en el proceso de hidratación del cemento, lo que debido a su elevada avidez por el agua genera geles expansivos, que provocan importantes tensiones disruptivas en el ...
