The effective dynamic properties of specific periodic structures involving rubber-like materials can be adjusted by pre-strain, thus facilitating the design custom acoustic filters. While nonlinear viscoelastic behaviour is one main features soft solids, it has been rarely incorporated in study such phononic media. Here, we response solids within a 'small-on-large' acoustoelasticity framework, ...

A combined experimental and numerical study is undertaken to examine the effects of pre-machined holes on strain localization and overall ductility in eutectic tin-lead alloy. Thin-sheet specimens with equal-sized holes aligned in the tensile loading direction are used. The tensile tests were performed at room temperature with a nominal strain rate of 0.001 s . The specimen, containing one hole...

Nuclear retention of pre-mRNAs is tightly regulated by several security mechanisms that prevent pre-mRNA export into the cytoplasm. Recently, spliceostatin A, a methylated derivative of a potent antitumor microbial metabolite FR901464, was found to cause pre-mRNA accumulation and translation in mammalian cells. Here we report that spliceostatin A also inhibits splicing and nuclear retention of ...

BACKGROUND In recent years, the caregiving responsibilities of cancer patients' family members have increased dramatically. Reducing caregiver strain and burden supports the mission of professional nursing. OBJECTIVES The aim of this study was to determine and compare the caregiver strain index scores of breast cancer informal caregivers, before and after a patient-caregiver educational and t...

OBJECTIVE The objective of this study was to investigate the relationship between acute decreases in right ventricular volume during Valsalva strain (with resultant changes in autonomic neural tone) and measures of local endocardial repolarization time independent of heart rate and autonomic neural tone. METHODS Patients implanted with a stimulus to T wave (Stim-T) sensing pacemaker specially...

Efficient and stable flexible perovskite solar cells were fabricated with reduced residual strain by pre-applying on the substrate. The showed efficiencies of up to 18.7% operational stability lifetime exceeding 700 h.

OBJECTIVES To analyze the role of the capsular type in pneumococci causing relapse and reinfection episodes of acute exacerbation in COPD patients. METHODS A total of 79 patients with 116 recurrent episodes of acute exacerbations caused by S. pneumoniae were included into this study (1995-2010). A relapse episode was considered when two consecutive episodes were caused by the same strain (ide...

This paper studies the effects of frequency, pre-strain and electrode types on the dielectric property of a commercially available and most widely used acrylic elastomer, VHB 4910. The acrylic VHB film is pre-stretched in biaxial directions with the help of an in-house developed biaxial stretching device. The stretched film has been sandwiched between two card board frames to prepare samples of...

The aim of this study was to investigate the effect of sodium dodecyl sulfate (SDS), citric acid, and hydrogen peroxide (H2O2), alone or in combination, on reducing the population of four foodborne pathogens, including Escherichia coli, Listeria monocytogenes, Salmonella typhimurium, and Staphylococcus aureus on eggshells. In each series of tests, eight fresh eggs were inoculated with each bact...
