Fluctuations in tumor blood flow are common and attributed to factors such as vasomotion or local vascular structure, yet, because vessel structure and physiology are host-derived, animal strain of tumor propagation may further determine blood flow characteristics. In the present report, baseline and stress-altered tumor hemodynamics as a function of murine strain were studied using radiation-i...

Embedded optical fibre sensors are considered for structural health monitoring purposes in numerous applications. In fibre reinforced plastics, embedded fibre Bragg gratings are found to be one of the most popular and reliable solutions for strain monitoring. Despite of their growing popularity, users should keep in mind their shortcomings, many of which are associated with the embedding proces...

Fiber-reinforced polymer (FRP) has been increasingly applied to steel structures for structural strengthening or crack repair, given its high strength-to-weight ratio and high stiffness-to-weight ratio. Cracks in steel structures are the dominant hidden threats to structural safety. However, it is difficult to monitor structural cracks under FRP coverage and there is little related research. In...

Natural phenomena like earthquakes, landslides, avalanches or mud flows can cause severe damages of railway tracks. Today’s monitoring concepts either focus on a permanent monitoring of known problematic sites or an epochwise measurement of the railway track with special measurement cars. In this paper we present a new approach for continuous monitoring of railway tracks over long distances. Th...

The safety of the 610 m Guangzhou New Television Tower, due to become China's tallest structure on completion, is an issue that concerns many parties because of the lack of sufficient experience, official design codes, and construction guidelines for such a skyscraper. This paper investigates the strain/stress development of this super-tall structure through the integration of finite element an...

Effective use of conditional Cre recombinase-loxP gene modification requires Cre-expressing mouse strains with defined patterns of expression. To assess the in vivo functionality of Cre-expressing mice, we have engineered an improved reporter strain for monitoring Cre-mediated excisions. The beta-galactosidase-neomycin phosphotransferase fusion gene (betageo)-trapped ROSA26 locus was modified b...

Splitting of HOLZ lines on CBED patterns is systematically observed at the proximity of interfaces and prevents local strain measurements by monitoring of line shifts. It was previously suggested that such splitting occurs due to interface-strain relaxation in thin TEM lamella. Here we confirm this model by dynamical simulation of CBED patterns using the multislice algorithm.

background: heat stress is a common and usual problem in industries. several indices, including wet bulb globe temperature (wbgt), are used to evaluate heat stress. however, wbgt index has limitations such as high cost and response time. it is not thus suitable as a screening tool. heat strain scoring index (hssi) is also an observational-judgmental technique that has been developed for primary...

As an clean renewable energy source wind energy is highly regarded by various countries in the world. Wind turbine blade is one of the most important components in wind turbine. It is the key component for receiving wind energy. As turbine size steps up and the size of modern turbine blade increases, condition monitoring and maintenance of blades become more important. Strain detection is one o...
