Articular cartilage is a soft tissue showing inelastic properties. Under cyclic loading, inelastic materials may dissipate mechanical energy into heat. In knee cartilage, due to an intrinsic reduced heat convection related to its avascularity, a local temperature increase could be observed. This phenomenon is referred to as self-heating. As cells are sensitive to temperature variation, the ener...

Do insect larvae ever self-heat significantly from their own metabolic activity and, if so, under what sets of environmental temperatures and across what ranges of body size? We examine these questions using larvae of the Japanese rhinoceros beetle (Trypoxylus dichotomus), chosen for their large size (>20g), simple body plan, and underground lifestyle. Using CO2 respirometry, we measured larval...

background and purpose: diabetes is the most common metabolic disorder which is caused by defects in insulin secretion, insulin action, or both .the most important factor in managing diabetes is self-care. since diabetes self-care behaviors are multifactorial and these factors may directly or indirectly affect self-care, it is possible through the application of path analysis to estimate the di...

In self-emulsification higher-energy micrometre and sub-micrometre oil droplets are spontaneously produced from larger ones and only a few such methods are known. They usually involve a one-time reduction in oil solubility in the continuous medium via changing temperature or solvents or a phase inversion in which the preferred curvature of the interfacial surfactant layer changes its sign. Here...

(CSE) performed an analysis of the self-initiated thermal decomposition phenomenon of paint-loaded filters that has occurred on several occasions as reported by the Iowa Waste Reduction Center. By conducting a series of self-heating tests on samples of filters loaded with paint, CSE has shown that in selected circumstances the exothermic decomposition of the paint-loaded filters could lead to t...

A mathematical model was developed to predict the self-heating and self-ignition processes of relatively dry biomass during storage, considering in detail effects moisture exchange behaviour, low-temperature oxidation reaction associated heat mass transfer. Basket heating tests on fir pellets powder at temperatures 180–200 °C were conducted observe process determine kinetics chemical for valida...

A self-contained derivation of the IPESD models [Majda, A.J., Klein, R., 2003. Systematic multi-scale models for the tropics. J. Atmos. Sci. 60, 393–408] governing synoptic and planetary scale tropical flows is provided. This derivation demonstrates the analytic tractability of the model and the effect of zonally and meridionally tilted synoptic scale heating on the forcing of planetary scale f...

in this research, tested factors were margarine types (contractive effects between types of oils in base of margarine such as palm super olein – partially hydrogenated canola oil – 50:50 mixture of palm super olein and partially hydrogenated canola oil and liquid canola) and different moisture (16-8-4%) as the first factor and heating time is the second factor. every margarines spend 3 times he...
