Dynamic amplification factor for bridges with span length from 10 to 35 meters

Engineering Structures and Technologies, 2015
Heavy traffic on the bridge cause not only static effects, but also dynamic effects. These effects can be indicated by different dynamic parameters like – natural frequency, bridge logarithmical decrement, bridge acceleration and dynamic amplification ...

Exact Dynamic Characteristic Analysis of Steel-Concrete Composite Continuous Beams

Shock and Vibration, 2021
The free vibration characteristics of steel-concrete composite continuous beams (SCCCBs) are analyzed based on the Euler–Bernoulli beam theory. A modified dynamic direct stiffness method has been developed, which can be used to analyze the SCCCBs with ...

Sonographic determination of liver and spleen sizes in patients with sickle cell disease at Gombe, Nigeria

CHRISMED Journal of Health and Research, 2018
Background: Ultrasonography is a safe, reproducible, and accurate diagnostic imaging modality in the evaluation of the effects of sickle cell anemia (SCA) on the sizes of liver and spleen. The study is aimed at determining the size of liver and spleen in

Secretory Phospholipase A2 in Patients With Sickle Cell Disease Hospitalized for Vaso‐Occlusive Pain Episodes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Secretory phospholipase A2 (sPLA2) is an inflammatory mediator linked to acute chest syndrome (ACS) in sickle cell disease (SCD), a serious complication that can develop during an acute vaso‐occlusive pain episode (VOE). Plasma sPLA2 levels have been proposed as a potential biomarker for predicting ACS onset.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
