In this paper we express the disentangling, or the formation of a function of several noncommuting operators using Cauchy’s Integral Formula in several complex variables. It is seen that the disentangling of a given function f can be expressed as a contour integral around the boundary of a polydisk where the standard Cauchy kernel is replaced by the disentangling of the Cauchy kernel expressed ...

ing earnings for shareholders. Return on equity measures net income less preferred dividends against total stockholder’s equity. The three primary drivers of ROE are better sales (or turnover), greater margins and higher debt levels, each of which can lead to a higher ROE. Although return on equity is a useful tool, it does not tell you what factors are helping or hurting the company’s performa...

In this paper, an approximation for n! (given by Stirling’s formula) is calculated. The accuracy of this formula is also presented. Some improvisations on the accuracy are explored.

Both the quality of the results of TEX s formula layout algorithm and the complexity of its description in the TEXbook are hard to beat The algorithm is verbally described as an imperative program with very complex control ow and complicated manipulations of the data structures representing formulae In a forthcoming textbook we describe TEX s formula layout algorithm as a functional program tra...

shampoos are products which remove surface grease and dirt from the hair shaft and scalp. the cleansing or detergent action of a shampoo is a primary function. however, the foaming characteristic of a shampoo has an important role in its acceptability. often alkanolamides are used for the formation of a stable foam; but because of producing nitrosamines, they are potentially carcinogenic compou...

in this paper, by using the survival models, survival functions for the time from birth to the event of using formula (i.e. the time that baby in fed by breast milk) in urban and rural areas of takestan (iran, winter 1998) are reported. later the relation between the mentioned time and some factors are also discussed. the kaplan-meire method and cox regression are used in this paper as well. 48...

purpose: to report the results of different methods for true corneal power and intraocular lens (iol) power calculation in 10 eyes with previous radial keratotomy (rk) with or without astigmatic keratotomy. methods: in this case series including 10 eyes of 7 patients who had undergone rk with or without astigmatic keratotomy, we firstly determined corneal power using two methods: contact lens m...

Determination of drug residues in food is of great importance due to their toxicity. Long-term exposure with low level of drug residues could be important, especially in children. Based on document study, oxytetracycline (OTC) is a prophylaxis and treatment agent for great number of diseases and possesses a broad spectrum activity against many pathogenic organisms and can be toxic or cause alle...
