Integrity Analysis of the Sheath Considering Temperature Effect under Deep and Large-Scale Multi-Section Hydraulic Fracturing

Energies, 2021
Different operations make the borehole temperature change and cause periodic stresses, which often cause variations in the stress state of the sheath or damage. In this paper, the effect of temperature on sheath integrity is investigated.

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify

A General Framework to Simulate Soil–Structure Interface Behaviour Using Advanced Constitutive Models

Modelling
The importance of using sophisticated interface models to obtain realistic numerical solutions of soil–structure interaction (SSI) problems has been recognised in recent decades. With this aim, various advanced interface models have been developed, which

Considerations for Discrete Element Modeling of Rock Cutting [PDF]

, 2013
This study attempts to build a framework within the Discrete Element Method (DEM) to produce a reliable predictive tool in rock cutting applications, such that the cutting forces and fragmentation process are reasonably estimated. The study is limited to

Bio‐Based Sodium Alginate Beads Reinforced With Microalgae (Limnospira platensis): Structure–Property Relationships and Controlled Release Potential

Journal of Applied Polymer Science, EarlyView.
Development of sodium alginate beads doped with Limnospira platensis, designed for the gradual release of nutrients and bioactive molecules into soil. The biomaterial combines biodegradability, controlled‐release potential, and microalgal biomass valorization, contributing to reduced nutrient losses through leaching and the development of more ...

THE CONSISTENCY CONDITIONS FOR DENSITY LIMITS OF HYPOPLASTIC CONSTITUTIVE LAW

TASK Quarterly, 2000
The so called phase diagram of grain skeletons illustrates the range of possible void ratios between the pressure dependent bounds ei and et. It can be shown that in the framework of the actual hypoplastic model these bounds can be surpassed by ...

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

The Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

SPH-Based Simulations for Slope Failure Considering Soil-Rock Interaction

, 2015
Both small and large deformations of soil and soil-rock interaction are the key features in the post-failure process of natural slopes. As one of Lagrange meshless particle methods, the Smooth Particle Hydrodynamics (SPH) method has obvious advantage in ...

Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

Archaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...
