In this paper we present several proofs on the extension of M. Riesz fractional integration and di¤erentiation to the contexts of spaces of homogeneous type and measure metric spaces with non-doubling measures. 1. Introduction, some de…nitions, and a basic lemma Professor M. Ash asked me to write a survey article on some of the results that Stephen Vági and I obtained in the nineties on fractio...

Polymeric materials have become an integral part of every aspect of today's industry. They have wide applications, inter alia, in areas such as medicine, food industry and agriculture. In agriculture, for example, they are used for the production of pots, irrigation systems and for soil mulching. The aim of this study was the attempt to produce a biodecomposable agricultural mat, by coating cot...

Agricultural research generates highly locale-specific as well as abstract or location-neutral information. Because of this diversity and the need to build prescriptive practices out of such information, agricultural research information management on the web requires semantic enablement. Keyword assignment is an important step towards achieving this. In this paper we describe a taxonomy called...

In the past few years, event detection has drawn a lot of attention. We proposed an efficient method to detect event in this paper. An event is defined as a set of descriptive, collocated keywords in this paper. Intuitively, documents that describe the same event will contain similar sets of keywords. Individual events will form clusters in the graph of keywords for a document collection. We bu...

the objectives of the present study were to evaluate spring wheat recombinant inbred lines (rils) of diverse origin by estimating genetic parameters viz., variability, character association, cluster analysis, and principal component analysis (pca) for spot blotch resistance and yield components at bhu agricultural research farm during 2010-2011. grain yield per plot was significantly and positi...

This article explores the theoretical issues of creating clusters, their tasks and capabilities, impact clusters on regional competitiveness. The internationally standardized experience in creation development agricultural were learned deeply this article. directions Uzbekistan are indicated.

Abstract The article discusses the issues and a number of technical recommendations for effective use existing agricultural reclamation equipment available in clusters republic, as well prospects their development large-scale implementation technological processes those problems that may arise during operation ways to eliminate them production conditions.
