Software maintainability is one important aspect in the evolution of a software product. Several coupling measures have been introduced to identify and measure the design complexity of an object oriented (OO) systems. The coupling metrics proposed in this paper recognizes the complexity between inheritance and interface programming. This paper presents measurements of Coupling between Object (C...

Saure Carhoxypeptidase, welche Phenylalanin von CbO-Leu-Phe-OH bei pH 5,3 abspaltet, ist ein in höheren Angiospermen weit verbreitetes Enzym. Es scheint dagegen in primitiven Angiospermen (Fagus und Magnolia) sowie in Gymnospermen und Kryptogamen (Ausnahme: Equisetum) zu fehlen. Bei Zitrone ist die Aktivität saurer Carboxypeptidase von Natur und Alter der extrahierten Gewebe abhängig (Exocarp u...

exploitation of the full potential of any hybrid requires the possessing of genetically high-purity seeds. commercial soybean hybrids have been developed using a cytoplasmic male sterility (cms) system. in order to avoid reduction in yield caused by using low-purity seeds, development of a simple, rapid, and accurate method for hybrid purity assessment is of great essence and significance. ther...

The federal government buys many goods and services that are expected to increase private-sector productivity—that is, the ability of the private-sector workforce, using the stock of capital, to produce goods and services. Such purchases by the federal government are called investment. In an earlier report, the Congressional Budget Office examined various aspects of federal investment itself, s...

Community based organizations (CBOs) play a frontline role in HIV/AIDS prevention activities. CBOs face formidable challenges to effective delivery of HIV prevention services including client characteristics such as homelessness and CBO characteristics such as limited resources and staff turnover. Despite these obstacles, CBOs are generally well positioned to deliver services to specific high-r...

in this paper, we introduce hybrid of block-pulse functions and bernstein polynomials and derive operational matrices of integration, dual, differentiation, product and delay of these hybrid functions by a general procedure that can be used for other polynomials or orthogonal functions. then, we utilize them to solvedelay differential equations and time-delay system. the method is based upon ex...

dehghan (ksc 400) is an early-medium maturity grain maize hybrid that has been developed from a cross between two inbred lines (ke72012/12×k1263/1). this cross was carried out in 1997, for the first time. the characteristics of dehghan hybrid were studied in different trials (preliminary, semi final, final and on farm trials) in several locations during 1997 to 2005. the mean grain yield of the...
