We exhibit a graceful labelling for each generalised Petersen graph P8t,3 with t ≥ 1. As an easy consequence, we obtain that for any fixed t the corresponding graph is the unique starter graph for a cyclic edgedecomposition of the complete graph K2t+1. Due to its extreme versatility, the technique employed looks promising for finding new graceful labellings, not necessarily involving generalise...

There is a complicated relation between cold flat rolling parameters such as effective input parameters of cold rolling, output cold rolling force and exit thickness of strips. In many mathematical models, the effect of some cold rolling parameters has been ignored and the outputs have not a desirable accuracy. In the other hand, there is a special relation among input thickness of strips, the ...

The aim of this paper is to retrieve the temperature-dependent refractive index distribution in parallel-plane semi-transparent media with combined conduction-radiation heat transfer, by measurement exit intensities over boundaries. finite volume method combination discrete ordinates used solve energy equation. results direct solution for both linear-spatially and linear-temperature-dependent d...

As far as we know, no dimensionless solutions for infiltrated flow under dams in anisotropic media exist since those that can be found manuals refer to isotropic soils. The novelty of this work is the presentation universal form abaci water flow, average exit gradient, uplift force, and its application point type soil. These are obtained by discriminated nondimensionalization technique governin...

Sodium-Galactose Transporter (SGLT) is a secondary active symporter which accumulates sugars into cells by using the electrochemical gradient of Na+ across the membrane. Previous computational studies provided insights into the release process of the two ligands (galactose and sodium ion) into the cytoplasm from the inward-facing conformation of Vibrio parahaemolyticus sodium/galactose transpor...

Like many voltage-sensitive ion pumps, cytochrome c oxidase is inhibited by zinc. Binding of zinc to the outside surface of Rhodobacter sphaeroides cytochrome c oxidase inhibits the enzyme with a K(I) of < or = 5 microm when the enzyme is reconstituted into phospholipid vesicles in the presence of a membrane potential. In the absence of a membrane potential and a pH gradient, millimolar concent...

A facilitative transport system exists on the blood-brain barrier (BBB) that has been tacitly assumed to be a path for glutamate entry to the brain. However, glutamate is a non-essential amino acid whose brain content is much greater than plasma, and studies in vivo show that glutamate does not enter the brain in appreciable quantities except in those small regions with fenestrated capillaries ...

ABSTRACT Background: In vivo measurements of applied dose during radiotherapy treatment, is important to ensure accurate dose delivery to patients. Uncertainty in dose delivery should fall within ±5% of the prescribed dose as recommended by ICRU. Assessment of dose for radiotherapy applications performed with various types of detectors. In this study, semiconductor diodes were used which have s...
