the hydrophobic proteins of plant plasma membrane still remain largely unknown.  for example in the arabidopsis genome, receptor-like kinases (rlks) are plasma membrane proteins, functioning as the primary receptors in the signaling of stress conditions, hormones and the presence of pathogens form a diverse family of over 610 genes. a limited number of these proteins have appeard in protein pro...

AIMS To predict 5 year survival in patients with uveal malignant melanomas DNA indices were studied. METHODS Using 45 paraffin embedded uveal malignant melanomas, the DNA index and S phase fraction of each tumour were the predictor variables recorded. RESULTS Using the Cox proportional hazards model, aneuploid tumours and tumours which had an S phase fraction greater than 4% were significan...

nanofluids are colloidal suspension of nanoparticles in a base fluid and have superior thermal properties in comparison to their base fluids. novel properties of nanofluids are yet to be explored to the highest potential. currently extensive investigation has been done on thermal conductivity of metallic and oxide nanofluids. composites offer the advantage of tailor made properties and fluids w...

We consider two–phase metrics of the form φ(x, ξ) := αχBα(x) |ξ|+βχBα(x) |ξ|, where α,β are fixed positive constants, and Bα, Bβ are disjoint Borel sets whose union is R , and we prove that they are dense in the class of symmetric Finsler metrics φ satisfying α|ξ| ≤ φ(x, ξ) ≤ β|ξ| on R × R . Then we study the closure Cl(M θ ) of the class M α,β θ of two–phase periodic metrics with prescribed vo...

Abstract. This work studies the heat equation in a two-phase material with spherical inclusions. Under some appropriate scaling on the size, volume fraction and heat capacity of the inclusions, we derive a coupled system of partial differential equations governing the evolution of the temperature of each phase at a macroscopic level of description. The coupling terms describing the exchange of ...

Sea ice exhibits a marked transition in its fluid transport properties at a critical brine volume fraction pc of about 5 percent, or temperature Tc of about -5 degreesC for salinity of 5 parts per thousand. For temperatures warmer than Tc, brine carrying heat and nutrients can move through the ice, whereas for colder temperatures the ice is impermeable. This transition plays a key role in the g...

We propose a model for statistically inhomogeneous two-phase random media , including functionally graded materials, consisting of inhomogeneous fully penetrable (Poisson distributed) spheres. This model can be constructed for any speciied variation of volume fraction and permits one to represent and evaluate certain n-point correlation functions that statistically characterize the microstructu...

We propose a model for statistically inhomogeneous two-phase random media, including functionally graded materials, consisting of inhomogeneous fully penetrable ~Poisson distributed! spheres. This model can be constructed for any specified variation of volume fraction and permits one to represent and evaluate certain n-point correlation functions that statistically characterize the microstructu...

During the crossing of the place field of a pyramidal cell in the rat hippocampus, the firing phase of the cell decreases with respect to the local theta rhythm. This phase precession is usually studied on the basis of data in which many place field traversals are pooled together. Here we study properties of phase precession in single trials. We found that single-trial and pooled-trial phase pr...

For a two-phase swelling porous medium, two pressures have been previously defined thermodynamically in terms of intensive variables for each phase: one relating the change in energy with respect to specific volume, and the other relating the change in energy with respect to volume fraction. Within the framework of Hybrid Mixture Theory and hence the Coleman and Noll technique of exploiting the...
