Description of Polymer and Composite Hardening During Tensile Tests

Engineering Transactions, 1992
Tensile stress-strain curves of plastics and polymer composites are prepared and analyzed, the effects of temperature, water diffusion, heat treatment and notches being taken into account.

Integrated genomic and proteomic profiling reveals insights into chemoradiation resistance in cervical cancer

Molecular Oncology, EarlyView.
A comprehensive genomic and proteomic analysis of cervical cancer revealed STK11 and STX3 as a potential biomarkers of chemoradiation resistance. Our study demonstrated EGFR as a therapeutic target, paving the way for precision strategies to overcome treatment failure and the DNA repair pathway as a critical mechanism of resistance.

Calculation of composite elements of slabs in buildings, structures and fragments of spans of bridges

MATEC Web of Conferences, 2018
The calculation consists of two stages. The first one begins with the definition of their class, bearing capacity at temperature of 20 °C, according to EN 1992-1-1.

Assessment of thermal stress risk in mass concrete elements: use of expedited diagrams [PDF]

Revista IBRACON de Estruturas e Materiais
Large structural elements have been commonly observed in increasingly tall buildings, employing mass concrete elements in their foundations. In these elements, the internal heat generated by the cement hydration can be decisive for the occurrence of ...

Fracture–Mechanical Assessment of the Effect of Defects on the Fatigue Lifetime and Limit in Cast and Additively Manufactured Aluminum–Silicon Alloys from HCF to VHCF Regime

Metals, 2020
Aluminum–silicon alloys are commonly used in die-cast and additively manufactured (AM) light-weight components due to their good processability and high strength-to-weight ratio.

Manufacturing of Composites by Pressure Infiltration, Structure and Mechanical Properties [PDF]

, 2008
This paper presents the possibility of composite block production by using pressure infiltration technology. This method uses the pressure of an inert gas (usually argon or nitrogen) to force the melted matrix material to infiltrate the reinforcing ...

Elastic response of the electron fluid in intrinsic graphene: The collisionless regime [PDF]

, 2018
The elastic response of an electron fluid at finite frequencies is defined by the electron viscosity $\eta(\omega)$. We determine $\eta(\omega)$ for graphene at the charge neutrality point in the collisionless regime, including the leading corrections ...

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

Molecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

Cylic Stress-Strain Diagram of Non-Woven Fabrics

Journal of the Textile Machinary Society, 1965
目的不織布および天然皮革の変形性が, 繰り返し伸長曲線における残留伸び率および伸び減少率によって, その差異を表わすことの可能性を検討し, これが不織布を組立てている各種の要素によりどのように影響されるかを調べ, さらに他の解析方法との比較を試みた.結果その結果, 不織布の構成要素の変化が, 残留伸び率および伸び減少率の大きさにそのまま反映されることが認められ, それらが比較的よくその変形性の差異を示すとの結論を得た.また他の解析方法との関連も検討し, それが残留伸び率との相関が成立することを確認した.すなわち, 残留伸び率が繰り返し伸長性能を解析するための簡単な方法であることが認められた.
