Research on dynamic shrinkage of hydraulic flushing borehole based on fractional Maxwell creep model

Meikuang Anquan
Hydraulic flushing and permeability improving technology has been widely used in gas extraction in soft coal seams. However, the strength of soft coal is low, so creep deformation is easy to occur, resulting in serious borehole shrinkage and thus ...

Comparative Performance Analysis of Various Flat Plate Solar Collectors Incorporating Spiral and Square Arrangement of Circular Type Riser Tube

Energy Science &Engineering, EarlyView.
Three flat‐plate collectors with spiral and square coiled riser tubes were tested and it was found that the spiral type provides the best results with a thermal efficiency of 66.98% for a mass flow rate of 0.4 kg/min. Riser tube geometry is a key factor in optimizing flat‐plate collector output.

Knee joint line obliquity alters lateral meniscal root tension, tibiofemoral subluxation and compartment‐specific contact pressures

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The objective was to measure effects of joint line obliquity (JLO) on meniscus posterior root tension, tibiofemoral subluxation and contact pressures. It was hypothesised that a medial JLO would increase medial meniscal (MM) root tension, medial tibiofemoral subluxation and medial compartment contact pressure, and vice versa for ...

Comparative Effectiveness of Different Mulch Types and Application Rates for Reducing Runoff and Sediment Yield on Forest Skid Trails

Land Degradation &Development, EarlyView.
ABSTRACT Rehabilitation of skid trails following timber harvesting is critical for preserving forest soil integrity, particularly within ecologically sensitive ecosystems such as the Hyrcanian forests of northern Iran, a UNESCO World Heritage Site. Although mulching is widely recommended for erosion control, field evidence comparing different locally ...

Native Perennial Vegetation Buffer Strips Improve Structural Indicators of Riparian Protection in Mediterranean Agroecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Riparian zones in Mediterranean agroecosystems are highly vulnerable to degradation because cultivation often reaches stream edges and annual vegetation senesces during the late‐summer dry period, leaving soils exposed when the first erosive autumn rains occur.

New and Emerging Artificial Urinary Sphincters for Male Stress Urinary Incontinence: From Gold Standard to Next Generation

Neurourology and Urodynamics, EarlyView.
ABSTRACT Introduction For more than four decades, the AMS‐800 has remained the clinical benchmark device for the treatment of male stress urinary incontinence (SUI). Although it remains the gold standard for male SUI, the AMS‐800 has continued to have limitations such as suboptimal post‐operative continence rates, fixed hydraulic pressure, need for ...
