We use a novel 3D inter-/intracellular force microscopy technique based on 3D traction force microscopy to measure the cell-cell junctional and intracellular tensions in subconfluent and confluent vascular endothelial cell (EC) monolayers under static and shear flow conditions. We found that z-direction cell-cell junctional tensions are higher in confluent EC monolayers than those in subconflue...

Results from the Tasmanian Successful School Principal Project (SSPP) survey concur with the four major leadership tensions and dilemmas identified in a background literature review. These tensions and dilemmas relate to internal/external control, ethic of care/responsibility, and an emphasis on professional/personal as well as leadership/management. The results also offer new insights. These i...

The concentrations of 02 and CO2 in tissues (i.e., the extracellular tissue spaces) can be an index to the relationship between the blood flow and metabolism of an organ. Since the optimal performance of an organ is expected to occur between definable limits of the tissue 02 and CO2 tensions (1, 2), correct values for these gas tensions delineate the most suitable relationship between flow and ...

My partner gets nervous every time I see my psychotherapist because she doesn't like the idea of me talking about our relationship. For her, it's anxiety-producing because she fears there are things I tell my therapist that I don't tell her. For me, it's anxiety-producing because I feel like my therapy sessions should be a safe and confidential space for me and because I feel like having that s...

This project presents research-based art works that inquire into the tensions in everyday life from an ethical viewpoint of care, which sees people as embedded, "nested" in care-based relationships. Trust is the glue that holds these "nests" together. Care is the air that lifts them up, but tensions exist as well-between dependency and autonomy, vulnerability and strength, for example. The pull...

We show that the singular sources in the energy-momentum tensor for the RandallSundrum brane world, viewed as a solution of type IIB supergravity, are composed of two elements. One of these is a D3-brane source with tension opposite in sign to the RS tension in five dimensions; the other arises from patching two regions of flat ten-dimensional spacetime. This resolves an apparent discrepancy be...

A full scale transmission line section of three continuous spans was established. With the consideration of the equivalent mass of the accreted ice, steel cables are used to simulate the iced conductors. For different types of conductors and ice thickness, broken conductor experiments were carried out. Under different broken cases, time histories of the tensions and displacements at the middle ...

The US has been a major battle-ground amongst legislators coming to grips with the issue of embryonic stem cell research but the issue is reaching new heights in Italy. Nigel Williams reports.
