Spent coffee grounds applied as a top-dressing or incorporated into the soil can improve plant growth while reducing slug herbivory
(2022)Between 8 and 15 million tons of spent coffee grounds (SCG) are produced as global waste each year. To reduce waste to landfill, SCG are proposed as a carbon and nutrient source for degraded soils. SCG contain caffeine and ...

Spinning black holes for generalized scalar tensor theories in three dimensions
(2020)We consider a general class of scalar tensor theories in three dimensions whose action contains up to second-order derivatives of the scalar field with coupling functions that only depend on the standard kinetic term of ...

Stability analysis of a self-cycling fermentation model with state-dependent impulse times
Cordova-Lepe, Fernando
; ; (2014)
A self-cycling fermenter is a batch fermenter subject to recurrent emptyings of liquid volume followed by the refilling withnew fresh substrate. This article construc ts a modified model of self-cycling fermenter, which ...

Stability and bifurcation in the circular restricted (N + 2) -body problem in the sphere S2 with logarithmic potential
(2023)In this paper we study part of the dynamics of a circular restricted -body problem on the sphere and considering the logarithmic potential, where primaries remain in a ring type configuration (identical masses placed at ...

Stability in post-seasonal hematological profiles in response to high-competitive match-play loads within elite top-level European soccer players: Implications from a pilot study
(2018)Introduction: The stability of hematological status indices is a key determinant of optimal sport performance. The capacity to monitor hematological behaviors of elite soccer players may better explain the stresses placed ...

Stand structure, regeneration and seed dispersal patterns of nothofagus glauca (hualo) in central Chile
(2020)Growing interest in functional silviculture is promoting new approaches to the study of seed dispersal and regeneration, two of the key processes that determine the structure and dynamics of plant populations. Nothofagus ...

State-dependent TMS of inferior frontal and parietal cortices highlights integration of grip configuration and functional goals during action recognition
(2020)Understanding the object-directed actions of conspecifics not only implies recognition of the object (e.g., a pen) and processing of the motor components (e.g., grip configuration), but also identification of the functional ...

State-dependent tms over prefrontal cortex disrupts fear-memory reconsolidation and prevents the return of fear
(2020)Erasing maladaptive memories has been a challenge for years. A way to change fear memories is to target the process of reconsolidation, during which a retrieved memory transiently returns to a labile state, amenable to ...

Stealth Ellis wormholes in Horndeski theories
(2023)In this work we are revisiting the well studied Ellis wormhole solution in a Horndeski theory motivated from the Kaluza-Klein compactification procedure of the more fundamental higher dimensional Lovelock gravity. We show ...

Stem borers revisited: Host resistance, tolerance, and vulnerability determine levels of field damage from a complex of Asian rice stemborers
(2021)Yield losses from rice stem borers depend on the nature of the rice variety, the timing of attack, and the composition of the stem borer species assemblage. This study uses a range of phenotyping methods to distinguish ...

Stereoscopy does not improve metric distance estimations in virtual environments
(2020)Stereoscopy is widely used to render depth and perceptual spatial cues information in Virtual Environments (VEs). In literature, the use of stereoscopy in VEs reported advantages but also disadvantages on perceptual skills ...
