Study on Internal Pressure Calculation Methods for α-decay Radioisotope Heater Unit

Yuanzineng kexue jishu
The accumulation of excessive internal pressure within the hermetic containment of α-decay radioisotope heater units (RHU) may cause cladding rupture and risk of radioactive material release.

Wind-Induced Internal Pressures in Buildings

Wind Engineers, JAWE, 1993
Wind-induced internal pressures in buildings were analytically evaluated by using external pressure coefficients of six typical building models. The overall building porosity and the specific wall openings were taken into consideration in the evaluation. The analytical approach was based on the balance of flow through the openings.

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Coupled Burst and Fracture Failure Characteristics of Unbonded Flexible Riser Under Internal Pressure and Axial Tension

Journal of Marine Science and Engineering
Unbonded flexible risers, which can experience large bending deformation, are key equipment in advancing deep-sea exploration for marine resources. However, the riser experiences coupled loading effects from ocean environment.

Influence of acidic solutions on the strain distribution in glasspolyester composite pipes subjected to internal pressure

Zaštita Materijala, 2016
The basic subject of this paper was the determination of the strain distribution in glass-polyester composite pipes subjected to internal pressure. Firstly, the test was performed on virgin pipe segments (without the influence of acidic solution) to ...

Modeling of stress-strain state of piping systems with erosion and corrosion wear

Фізика і хімія твердого тіла, 2020
The problems of modeling the stress-deformed state of erosion or corrosion-worn rectilinear sections and the ball-shaped bends of pipeline systems are proposed to solve in a cylindrical coordinate system.

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

FEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly

Evaluation of the Efficiency and Strength Analysis of Profiled Heating Surfaces with Controlled Flow Separation in Marine Waste Heat Recovery Boilers

Polish Maritime Research
The utilisation of exhaust gas heat from diesel engines is one of the most effective ways to improve the performance of marine power plants. Achieving the same boiler performance, given the reduction in the exhaust gas temperature resulting from ...

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA

FEBS Open Bio, EarlyView.
Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.
