Conditional responding during simple Pavlovian conditioning is often characterized as a form of implicit memory. The extent to which this type of associative learning is independent of awareness is an issue of continuing debate. Previous studies have demonstrated conditioning in the absence of awareness. However, their results have been questioned based on methodological concerns with postexper...

With its portable, simple and affordable attributes, the Schmidt hammer (SH) is an ideal index apparatus, which underlies its increasing popularity and expanding range of applications. The SH rebound hardness value (R) is perhaps the most frequently used index in rock mechanics practice for estimating the uniaxial compressive strength (UCS) and the modulus of elasticity (E) of intact rock both ...

Panic disorder is characterized by the paroxysmal occurrence and fear of bodily symptoms. In recent years it has been proposed that patients "learn" to fear cardiorespiratory sensations through interoceptive conditioning. This study sought to model the initial stage of this process in healthy volunteers (N=44) using mild cardiac sensations. An additional aim was to explore whether anxiety sensi...

Abstract The rock uniaxial compressive strength (UCS) is the basic parameter for support designs in underground engineering. In particular, UCS should be obtained rapidly engineering with complex geological conditions, such as soft rock, fracture areas, and high stress, to adjust excavation plan ensure construction safety. To solve problem of obtaining real-time at sites, a forecast idea propos...

Biocemented Martian regolith simulant (MRS) columns were developed using a microalga, Thraustochytrium striatum. Response surface methodology was used to maximize the unconfined compressive strength (UCS) of biocemented MRS towards particle size, cell biomass loading, and nutrient (CaCl2/urea) loading. Overall, UCS increased with increase loading while medium size achieved highest UCS. But didn...

Los métodos para la clasificación de uso y cobertura del suelo (UCS) han mostrado avances importantes en los últimos años, como incorporación las técnicas aprendizaje automático (machine learning-ML) que ganado popularidad aceptación por sus resultados. Sin embargo, falta consensos metodológicos ha provocado una aplicación desordenada ML UCS. Por lo a través revisión bibliográfica practicada se...

Please cite this article in press as: Tinoco J et al. A columns over time. Constr Build Mater (2010), Jet grouting (JG) is a soil treatment technique which is the best solution for several soil improvement problems. However, JG lacks design rules and quality controls. As a result, the main JG works are planned from empirical rules that are too conservative. The development of rational models to...

Fear-conditioning is one of the most widely used paradigms in attempts to unravel the processes and mechanisms underlying learning and plasticity. In most of the Pavlovian conditioning paradigms auditory stimulus is used as a conditioned stimulus (CS), but conditioning can be accomplished also to tactile CS. The whisker-to-barrel tactile system in mice offers convenient way to investigate the b...

An experimental study was performed to investigate the effect of subcritical carbon dioxide (CO2) adsorption on mechanical properties of shales with different coring directions. Uniaxial compressive strength (UCS) tests were conducted on shale samples with different CO2 adsorption time at a pressure of 7 MPa and a temperature of 40 ̋C. The crack propagation and the failure mechanism of shale sa...
