Supercooled water does not behave like a simple liquid, but instead shows a number of anomalous properties. These include the diffusion coefficient [2] or the kinematic viscosity [3] which show anomalous pressure dependencies on compression up to 200MPa, whereas beyond 200 MPa the expected behaviour is observed. To explain these anomalies the second critical point hypothesis has been put forwar...

Under special conditions bacteria excrete an attractant and aggregate. The high density regions initially collapse into cylindrical structures, which subsequently destabilize and break up into spherical aggregates. This paper presents a theoretical description of the process, from the structure of the collapsing cylinder to the spacing of the final aggregates. We show that cylindrical collapse ...

pediatric mandibular fractures have been successfully managed in various ways. the use of a lingual splint is an option. this article presents a 4-year old boy who was treated by an alternative conservative method with a combination of an arch bar plus a lingual splint, circum-mandibular wiring and imf for the reduction, stabilization and fixation of a severely displaced bilateral man dibular b...

When a human grasps a cylindrical object, feedback on the orientation of the cylinder with respect to the axes of the digits is crucial for successful manipulation of the object. We measured the ability of humans to discriminate the orientations of cylinders passively contacting the fingerpad. For a cylinder of curvature of 521 m-1 (radius, 1.92 mm) subjects were able to discriminate, at the 75...

Local convective heat transfer coefficients were measured on a two-diameter long cylinder in axial flows of air at conditions unexplored so far, by using thermochromic liquid crystals (TLC) coated on an electrically heated strip-foil consisting bonded to the external surfaces. The Reynolds numbers (Re) based on the cylinder diameter were between 8.9 · 10 and 6.17 · 10, and the flow in front of ...

The subject area covered by this review is a large and important one and to do it full justice would require a larger format than is available here. However, an attempt is made to outline the history of some of the more important developments and to include most major techniques. Taylor impact, Hopkinson bar testing in its various forms and 1-D plate impact are all considered in some detail. Hi...

Theoretical and experimental investigations indicate that at high loads such as 3/4 throttling or more speeds 3000 rpm more, the exhaust gas temperatures of Internal Combustion engines are about 900-1000 K. The amount heat wasted with is equivalent to power them. By considering this feature engines, a Hybrid engine consisting an (IC) gamma type Stirling was proposed analyzed from thermodynamic ...

drought stress is one of the serious problems that restricted agronomic plant production worldwide. inmolecular level, the harmful effect of drought stress is mostly caused by producing of large amount ofreactive oxygen species (ros). catalase and metallothionein genes have a crucial role to mope the hydrogenperoxide (h2o2) resulting reducing oxidative damage. in this research the gene expressi...

We demonstrate that the temperature-dependent phase behaviors of parallel and perpendicular cylinder-forming block copolymers are governed by domain-domain segregation forces inherently present in block copolymer material itself. With increasing temperature, a parallel cylinder-forming block copolymer experienced a parallel cylinder straightening process before the order-disorder transition (OD...
