Responses of the Brans-Dicke field due to gravitational collapses

, 2010
We study responses of the Brans-Dicke field due to gravitational collapses of scalar field pulses using numerical simulations. Double-null formalism is employed to implement the numerical simulations.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, EarlyView.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

A new perspective on gravitational collapse: a comprehensive analysis using $$\Theta $$ Θ parametrization

European Physical Journal C: Particles and Fields
In this article, we have studied some new facets of gravitational collapse, beyond conventional notions of black holes, and naked singularities. The present work is focused on the unresolved problems of theoretical physics concerning the final fate of ...

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

Journal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger

Enhancing Soil Aggregation and Water Retention by Applying Kaolinite Clay to Post‐Tin‐Mined Land on Belitung Island, Indonesia

Land Degradation &Development, EarlyView.
ABSTRACT Post‐mining sandy soils have low water retention, which causes soil particle separation and persistent soil erosion. Although organic matter is commonly used for soil restoration, it is lightweight, washes away during heavy rain, and decomposes under strong sunlight.

Gravitational Collapse of Massless Fields in an Expanding Universe

EPJ Web of Conferences, 2018
Gravitational collapse of a massless scalar field with the periodic boundary condition in a cubic box is reported. This system can be regarded as a lattice universe model.

Estimation of Excess Ice and Thaw Settlement in Frozen Soil Using Industrial Computed Tomography

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost thaw can induce terrain instabilities and hazards as a result of the loss of excess ice from host sediments. The loss of excess ice threatens the integrity of infrastructure and drives ecosystem changes across northern landscapes. This study tests a nondestructive approach to estimate excess ice and potential thaw settlement using ...

Gravitational-wave and Gravitational-wave Memory Signatures of Core-collapse Supernovae

The Astrophysical Journal
In this paper, we calculate the energy, signal-to-noise ratio (SNR), detection range, and angular anisotropy of the matter, matter memory, and neutrino memory gravitational-wave (GW) signatures of 21 three-dimensional initially nonrotating core-collapse ...
