Introduction: To identify the strongest peak load resistance among four mallet finger fracture fixation methods (Kirschner wire, pull-out wire, tension-band wiring and the JuggerKnot™ (Biomet) soft anchor fixation).
Methods: Fixation techniques were assigned among 24 specimens from six cadaveric human hands in a randomized block fashion. Peak load resistance was tested at 30°, 45° and 60° of flexion of the distal interphalangeal joint.
Results: The mean peak load of tension-band wiring was 67.8 N at 60° of flexion which was most superior. The JuggerKnot™ fixation had mean peak loads of 13.35 N (30°), 22.51 N (45°) and 32.96 N (60°). No complications of implant failure or fragmentation of the dorsal fragment was noted.
Conclusions: Tension-band wiring was the strongest fixation method but was most prominent on the skin surface as seen in three specimens. The JuggerKnot™ soft anchor fixation had similar peak load resistance as k-wire fixation and pull-out wiring.

Background: Both listening to music during warm-up and consuming caffeine before exercise have been independently shown to enhance athletic performance. However, the potential synergistic effects of combining these strategies remain largely unexplored. To date, only two studies have reported additional benefits to combining music during warm-up with a caffeine dose of 3 mg/kg on taekwondo-specific performance tasks.

Despite decades of extensive studies, the mechanism of concrete creep remains a subject of debate, mainly due to the complex nature of cement microstructure. This complexity is further amplified by the interplay between water and the cement microstructure. The present study aimed to better understand the creep mechanism through creep tests on microprisms of cement paste at hygral equilibrium.

The amphibian chytrid fungus, (), has been implicated as an agent of acute declines in amphibian populations worldwide. East Asian amphibians have been coexisting with for long periods and thus are considered resistant; among the many is the Japanese tree frog, . Our study focused infection effects on reproductive behaviors and physiological parameters in as a function of better understanding the chronic effect of the disease on long-term population viability.

To investigate the statistical laws of acoustic emission energy (AEE) avalanche dynamics of sandstone under varying fracture lengths and dip angles, as well as to determine the relationship between acoustic emission (AE) parameters and damage variables, we studied the mechanical properties and AE characteristics of sandstone with a single fracture subjected to uniaxial compression with the aid of the Shimadzu AG-IS test system and the PCI-2 AE system. The AEE characteristics of fractured sandstone under load were analyzed based on the statistical method of avalanche dynamics, with emphasis on AEE distribution, aftershock sequence, and waiting time distribution. The Weibull distribution function that incorporates a correction coefficient β was employed to optimize the Weibull parameters based on the strain equivalent hypothesis theory, which led to the establishment of a statistical damage constitutive model for fractured rock.

In order to achieve the carbon peak and carbon neutrality goals, more and more industries were carrying out carbon emission reduction. Of course, carbon emission reduction in the wastewater treatment was also crucial. This study developed a pre-coagulation process to prevent some pollutants (28-33% of total nitrogen and other pollutants such as organic matter) from entering the biochemical treatment stage, thereby reducing carbon emissions in the wastewater treatment.
