section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
In this paper, we describe an approach to Web Service development and deployment that improves consistency among related Web Services and maps out a suggested pathway for the evolution of Web Service adoption. We suggest an approach that will allow developers to move from statically bound Web Services to Web Services that are dynamically discovered and consumed and ultimately leading to fully a...
geo-statistical distribution of heavy metals in karoon river’s soil by geographic information system
introduction: soil has an important role in nutrient cycle and an important function in storage, refinement, and movement of nutrients for the living and non-living parts. soil pollution of heavy metals and elements is one of the common pollution impacts of human activities, especially industry. realization of distribution pattern of these elements and their anthropogenic sources is a major par...
By interrupting the traditional approach to the distinctiveness of the order of knowledge and the order of nature (which was the procedure of many philosophers like Aristotle, and his scholastic disciples, more especially of Thomas Aquinas and even Descartes and Cartesian), and acquiring a unified science, Spinoza changes the customary order of philosophizing and begins his famous book, Ethics,...
During the last decade, upon formation of the design-led planning approach, the necessity of simultaneous and interactive consideration of urban planning and design was proposed. Since organizing the physical form of the city is one of the main elements of urban design, the recognition of city's physical features and the design of the built form became a focus towards the elevation of the urban...
let $m$ be a module over a commutative ring $r$ and let $n$ be a proper submodule of $m$. the total graph of $m$ over $r$ with respect to $n$, denoted by $t(gamma_{n}(m))$, have been introduced and studied in [2]. in this paper, a generalization of the total graph $t(gamma_{n}(m))$, denoted by $t(gamma_{n,i}(m))$ is presented, where $i$ is an ideal of $r$. it is the graph with all elements of $...
Abstract The article begins with a response to recent contribution by Jensen, in which he has criticized several aspects of the use triads elements, including Döbereiner’s original introduction concept and modern atomic number some authors myself. Such are groups three one approximately average weight other two as well having intermediate chemical reactivity. I also examine Jensen’s attempted r...
An international group of clinicians working in the field of dysmorphology has initiated the standardization of terms used to describe human morphology. The goals are to standardize these terms and reach consensus regarding their definitions. In this way, we will increase the utility of descriptions of the human phenotype and facilitate reliable comparisons of findings among patients. Discussio...
