Interacting Three Fluid System and Thermodynamics of the Universe Bounded by the Event Horizon [PDF]

, 2010
The work deals with the thermodynamics of the universe bounded by the event horizon. The matter in the universe has three constituents namely dark energy, dark matter and radiation in nature and interaction between then is assumed.

Dynamic black-hole entropy [PDF]

, 1998
We consider two non-statistical definitions of entropy for dynamic (non-stationary) black holes in spherical symmetry. The first is analogous to the original Clausius definition of thermodynamic entropy: there is a first law containing an energy-supply ...

Economic analysis of the business model for mass seed production of nutrient‐dense small indigenous fish species mola (Amblypharyngodon mola)

Journal of the World Aquaculture Society, Volume 56, Issue 4, August 2025.
Abstract Small indigenous fish species, such as mola carplet (Amblypharyngodon mola), play a crucial role in the diets of fish‐dependent populations in India due to their rich micronutrient content. Recognized as a key species for promoting nutrition‐sensitive aquaculture, mola has recently been successfully bred in hatcheries using standardized ...

Transcriptome response comparison between vector and non-vector aphids after feeding on virus-infected wheat plants

BMC Genomics, 2020
Background Plant viruses maintain intricate interactions with their vector and non-vector insects and can impact the fitness of insects. However, the details of their molecular and cellular mechanisms have not been studied well.

Timing of the Recent Migration and Intensification of the Southern Hemisphere Westerly Winds

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract In recent decades, the Southern Hemisphere westerly winds have strengthened and migrated south, attributed to greenhouse gas emissions and stratospheric ozone depletion. However, the onset and acceleration of these drivers is coincident with the start of the instrumental record, thus, hindering our ability to determine the significance of the ...

Thermodynamics of Lemaitre-Tolman-Bondi Model

, 2010
Here we consider our universe as inhomogeneous spherically symmetric Lemaitre-Tolman-Bondi Model and analyze the thermodynamics of this model of the universe. The trapping horizon is calculated and is found to coincide with the apparent horizon.

Small Non-Coding RNAs in the Regulatory Network of Wheat Dwarf Virus-Infected Wheat

Agriculture
Wheat dwarf virus (WDV) is a major constraint to global wheat production, causing severe yield losses and economic disruption. Understanding the molecular basis of wheat–WDV interactions is essential for developing resistant cultivars.

An Efficient Rice Virus-Induced Gene Silencing System Mediated by Wheat Dwarf Virus

Applied Sciences
The virus-induced gene silencing (VIGS) technique can effectively inhibit systemic viral infection by down-regulating plant endogenous gene expression, and it has become an important tool to study plant gene function.

Flow Resistance and Hydraulic Geometry in Gravel‐And Boulder‐Bed Rivers

Water Resources Research, Volume 61, Issue 3, March 2025.
Abstract The frictional resistance of river beds affects how water discharge is partitioned between depth and velocity, which is important in many aspects of hydrology, geomorphology, and aquatic ecology. Many of the most widely‐used resistance equations predict reach‐average velocity from relative submergence (RS), the ratio of mean flow depth to a ...

Breeding for resistance to insect-transmitted viruses in barley – an emerging challenge due to global warming

Journal für Kulturpflanzen, 2009
Due to global warming longer periods of higher temperature in autumn and winter are expected which may result in an increasing importance of insect-transmitted viruses.
