TL;DR: In this article, an upper bound solution is constructed for determining the die pressures developed during the cold forging of iron powder under axisymmetric and plane-strain condition. But the results so obtained are discussed critically to illustrate the interaction of the various parameters involved.

TL;DR: A parallel algorithm for polynomial interpolation implemented on a mesh of trees based on the Lagrange's interpolation formula that requires O(logn) time using n 2 processors where n is the number of input data points at which the values of the function will be specified.
Abstract: This paper presents a parallel algorithm for polynomial interpolation implemented on a mesh of trees. The algorithm is based on the Lagrange's interpolation formula. It requires O(logn) time using n 2 processors where n is the number of input data points at which the values of the function will be specified. We have also shown how the algorithm can be extended to the case when only p2 processors (p < n) will be available. The algorithm mapped on p2 processors has a time complexity of O((n2/p 2) log n).

TL;DR: After analyzing the Lauha Bhasma samples qualitatively and quantitatively, in-vivo studies on healthy adult male rabbits found increase in the haemoglobin content to be significant in case of the ayurvedic formulations as compared to the ferrous sulphate sample.
Abstract: After analyzing the Lauha Bhasma samples qualitatively and quantitatively, in-vivo studies on healthy adult male rabbits were carried out. Randomly selected anaemic rabbits were divided into different groups and three variants of Lauha Bhasma and ferrous sulphate sample were administered to each group. The effect of each formulation was monitored by measuring the haemoglobin (Hb) content spectrophotometrically (cyanomethaemoglobin method). Increase in the haemoglobin content was found to be significant in case of the ayurvedic formulations as compared to the ferrous sulphate sample.

TL;DR: Qualitative analysis indicates the presence of iron both in the ferric and the ferrous forms of Lauha Bhasma and a simple spectrophotometric method has been used for simultaneous determination of ferric ferrous and the total iron content in a single aliquot.
Abstract: Lauha Bhasma, an ayurvedic drug, is widely used in iron deficiency anaemia, this ancient drug is claimed to be better absorbed gastrointestinally, and is also claimed to be devoid of the usual side effects associated with administration of the allopathic iron preparations, Physical and chemical methods of standardization required for any quality preparation, is not found in the ayurvedic and the modern literatures for Lauha Bhasma. Thus an approach has been made to standardize Lauha Bhasma. For the purpose of analysis, samples of all the three commonly available variants of Lauha Bhasma were considered. Qualitative analysis indicates the presence of iron both in the ferric and the ferrous forms, A simple spectrophotometric method has been used for simultaneous determination of ferric ferrous and the total iron content in a single aliquot.
