Thermomechanical coupling seepage in fractured shale under stimulation of supercritical carbon dioxide

Frontiers in Earth Science
As a waterless fracturing fluids for gas shale stimulation with low viscosity and strong diffusibility, supercritical CO2 is promising than the water by avoiding the clay hydration expansion and reducing reservoir damage.

Analysis of Concrete Failure on the Descending Branch of the Load-Displacement Curve

Crystals, 2020
In this paper, load-displacement and stress-strain diagrams are considered for the uniaxial compression of concrete and under three-point bending. It is known that the destruction of such materials occurs on the descending branch of the load-displacement

Reservoir Permeability Evolution during the Process of CO₂-Enhanced Coalbed Methane Recovery

Energies, 2018
In this study, we have built a dual porosity/permeability model through accurately expressing the volumetric strain of matrix and fracture from a three-dimensional method which aims to reveal the reservoir permeability evolution during the process of CO2-

Effective anchorage stress of prestressed tendons in PC girders under varying tensioning sequences [PDF]

Archives of Civil Engineering
In current design codes, the standardized anchorage stress of prestressed tendons in concrete girders is uniform, which presents a notable challenge in accurately assessing the effective anchorage stress of girders with varying span lengths.

Lower shakedown limits of layered road structures under moving harmonic loads

Yantu gongcheng xuebao, 2022
The shakedown limits of layered road structures subjected to a moving harmonic load are studied. The inverse Fourier transform and the numerical integration are used to obtain the dynamic responses of a three-dimensional layered road structure in the ...

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

The Effect of Stress on Inflammation

Stress, 2001
Stress can either enhance or suppress aspects of the immune response, depending on the nature, duration, timing and intensity of the stressor. This paper focuses on the effects on inflammation of two behavioural stress paradigms: learned helplessness (La) and the open-field test (OF), and of the immunological stressor lipopolysaccharide (LPS).

Personalized Selumetinib Dosing in Pediatric Neurofibromatosis Type 1: Insights From a Pilot Therapeutic Drug Monitoring Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate selumetinib exposure using therapeutic drug monitoring (TDM) in pediatric patients with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PN), assess interpatient pharmacokinetic variability, and explore the relationship between drug exposure, clinical response, and adverse effects.

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

Theoretical and experimental studies on drilling cutting weight considering effective stress

Yantu gongcheng xuebao, 2018
Considering that the horizontal stress can not be ignored under deep mining, the new formula for drilling cutting weight is derived based on the effective stress.
